Title: Integrated folding bed

Description:
TECHNICAL FIELD 
     The present disclosure relates to the technical field of electric beds, and in particular to an integrated folding bed. 
     BACKGROUND 
     An electric bed has a bed frame, in which the height of the head or the foot of a bed board can be electrically controlled and the bending degree of the bed board can be freely adjusted, and can be classified into a slatted bed base type and a bed board type. 
     A bed body is generally folded in a transportation procedure in order to reduce transportation cost. However, the existing electric bed generally only can be folded in a length direction and is hardly folded in a width direction, especially a certain folding electric bed achieves folding and combining functions through detachable connection of a main bed body and expanding bed body such that the whole bed body is a separate type, and multiple expanding bed bodies need to be connected with the main bed body one by one in an assembling procedure and be stacked one by one in a folding procedure after the expanding bed bodies are detached from the main bed body so that the width of the bed body is inconveniently adjusted. 
     SUMMARY 
     An objective of the present disclosure is to provide an integrated folding bed, which solves a technical problem that the width of a bed body is inconveniently adjusted in the prior art. 
     To achieve the above objective, the present disclosure adopts the following technical solution: 
     The integrated folding bed comprises a bed body, bed feet and a bed frame, and the bed body is formed by multiple sequentially connected folding main bed boards, wherein an expanding bed board for widening the bed body is integrally arranged on one side face of the main bed board, the main bed board and the expanding bed board are connected through a hinge, two leaves of the hinge are respectively and fixedly mounted on an upper surface of the main bed board and an upper surface of the expanding bed board, and a pin of the hinge is arranged upwards. 
     Preferably, the bed foot comprises a cylindrical fixing part, a first inserting part, a second inserting part and embedding parts, one end of the fixing part is mounted on a lower surface of the bed frame, and the fixing part and the first inserting part are connected through one embedding part while the first inserting part and the second inserting part are connected through the other embedding part. 
     Preferably, one end of the two embedding parts is respectively mounted on the first inserting part and the second inserting part, and the embedding part located on the first inserting part is inserted into the second inserting part while the embedding part located on the second inserting part is inserted into the fixing part. 
     Preferably, L-shaped limiting grooves are opened in the embedding parts, limiting blocks penetrate horizontal sections of the limiting grooves and can move in the limiting grooves, and one end of one limiting block is fixedly mounted on an inner wall of the fixing part while one end of the other limiting block is fixedly mounted on an inner wall of the second inserting part. 
     Preferably, clamping grooves are opened in surfaces of the limiting blocks and match with the thickness of the embedding parts, and edge portions of the limiting grooves are inserted into the clamping grooves. 
     Preferably, inclined guide surfaces are arranged on two sides of an opening of each limiting groove. 
     Preferably, the fixing part and the first inserting part have the same outer diameter, and an outer diameter difference between the embedding part and the first inserting part is equal to the thickness of the fixing part. 
     Compared with the prior art, beneficial effects of the present disclosure lie in: 
     due to arrangement of a folding connection state between the expanding bed board and the main bed board, the size of the bed body can be reduced to reduce transportation cost, especially the expanding bed board and the main bed board are connected through the hinge so that an integrated structure of the bed body is maintained while a folding function is achieved; compared with the prior art that the expanding bed body is detached and separated from the main bed body, the present disclosure has the advantages: when the bed body is folded, movement trajectories of the expanding bed bodies in a folding procedure and positions of the folded expanding bed bodies are constant and not mutually interfered, so that the folding of the bed body is more convenient, and the folded bed body can be in an orderly state; similarly, in an unfolding procedure, compared with the prior art that the expanding bed body and the main bed body are separated and reassembled, the present disclosure has the advantages: the main bed body and the expanding bed body are always integrated after being folded, so in an unfolding procedure, the expanding bed bodies do not need to be connected with the main bed body one by one, convenience is improved, and a standard bed body structure can be shown after the bed body is unfolded.

     DESCRIPTION OF THE EMBODIMENTS 
     To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the present disclosure in detail with reference to the accompanying drawings and embodiments. Understandably, the described specific embodiments are merely used to explain the present disclosure, rather than to limit the present disclosure. 
     Referring to  FIG. 1  and  FIG. 2 , an integrated folding bed comprises a bed body  10 , bed feet  20  and a bed frame  40 , and the bed body  10  is formed by multiple sequentially connected folding main bed boards  100 , specifically, two sides between the main bed boards  100  are rotationally connected through rotary shafts to achieve folding and unfolding of two adjacent main bed boards  100 ; an expanding bed board  101  for widening the bed body is integrally arranged on one side face of the main bed board  100 , and the function of the expanding bed board  101  is: in use, the expanding bed board  101  can increase the size of the main bed board  100  so as to increase the size the whole bed body  10 , and the expanding bed board  101  is folded on the main bed board  100  in a transporting procedure to reduce the transportation size of the bed body  10  and then to reduce the transportation cost; referring to  FIG. 1  and  FIG. 2 , the main bed board  100  and the expanding bed board  101  are connected through a hinge  30 , two leaves  301  of the hinge  30  are respectively and fixedly mounted on an upper surface of the main bed board  100  and an upper surface of the expanding bed board  101 , and a pin  302  of the hinge  30  is arranged upwards; due to such arrangement, the main bed board  100  and the expanding bed board  101  can not only be folded and unfolded through the hinge  30 , and in an unfolding state, the pin  302  of the hinge  30  is arranged upwards so that the main bed board  100  and the expanding bed board  101  can be in contact so as to improve stability of the main bed board  100  and the expanding bed board  101 . 
     The embodiment has the following working procedure: 
     the main bed board  100  and the expanding bed board  101  rotate to be unfolded by taking the hinge  30  as an axis, or the main bed board  100  and the expanding bed board  101  rotate to be folded by taking the hinge  30  as the axis so as to achieve the folding and the unfolding of the whole bed body  10 , and then in the transportation procedure, the size of the bed body  10  can be reduced in a folding manner so as to reduce the transportation cost; especially the expanding bed board  101  and the main bed board  100  are connected through the hinge  30  such that the integrated structure of the bed body  10  is still maintained while the folding function is achieved; compared with the prior art that an expanding bed body  10  is directly detached and separated from the main bed board  10 , the present disclosure has the advantages: when the bed body  10  is folded, movement trajectories of the expanding bed bodies  10  in a folding procedure and positions of the folded expanding bed bodies are constant and not mutually interfered, so that the folding of the bed body  10  is more convenient, and the folded bed body can be in an orderly state; similarly, in an unfolding procedure, compared with the prior art that the expanding bed body  10  and the main bed body  10  are separated and reassembled, the present disclosure has the advantages: the main bed body  10  and the expanding bed body  10  are always integrated after being folded, so in the unfolding procedure, the expanding bed bodies  10  do not need to be connected with the main bed body  10  one by one, convenience is improved, and a standard bed body  10  structure can be shown after the bed body  10  is unfolded. 
     Referring to  FIG. 1  to  FIG. 6 , in the embodiment, the bed foot  20  comprises a cylindrical fixing part  201 , a first inserting part  202 , a second inserting part  208  and embedding parts  203 , one end of the fixing part  201  can be connected with the bed frame  40  in a welding manner, the fixing part  201  and the first inserting part  202  are connected through one embedding part  203  while the first inserting part  202  and the second inserting part  208  are connected through the other embedding part  203 , one end of the two embedding parts  203  is respectively mounted on the first inserting part  202  and the second inserting part  208 , and the embedding part  203  located on the first inserting part  202  is inserted into the second inserting part  208  while the embedding part  203  located on the second inserting part  208  is inserted into the fixing part  201 ; by respectively inserting the two embedding parts  203  into the fixing part  201  and the second inserting part  208 , the first inserting part  202  and the second inserting part  208  can be connected while the second inserting part  208  and the fixing part  201  can be connected so as to achieve assembly of the bed foot  20 ; the embedding part  203  is pulled out of the second inserting part  208  by pulling the first inserting part  202 , and the embedding part  203  is pulled out of the fixing part  201  by pulling the second inserting part  208  so that the bed foot  20  can be detached; and due to such arrangement, the bed foot  20  is detachable, after the bed foot  20  is detached in a bed body  10  folding procedure, the size of the bed foot  20  is reduced so as to further reduce the size of the folded bed body  10 , which is more convenient to transport. 
     Referring to  FIG. 5 ,  FIG. 6  and  FIG. 7 , L-shaped limiting grooves  204  are opened in the embedding parts  203 , limiting blocks  205  penetrate horizontal sections of the limiting grooves  204  and can move in the limiting grooves  204 , and one end of one limiting block  205  is fixedly mounted on an inner wall of the fixing part  201  while one end of the other limiting block  205  is fixedly mounted on an inner wall of the second inserting part  208 . When the embedding part  203  of the second inserting part  208  is inserted into the fixing part  201 , the opening of the corresponding limiting groove  204  is aligned to the corresponding limiting block  205  and then is inserted; when the embedding part  203  cannot be continuously inserted, the second inserting part  208  is rotated, the embedding part  203  rotates along with the rotating of the second inserting part  208  and drives the limiting groove  204  to rotate, and at this time, the limiting block  205  moves in the limiting groove  204 ; when the second inserting part  208  cannot be continuously rotated, the limiting block  205  moves to a furthest end of the horizontal section of the limiting groove  204 , and at this time, the limiting block  205  and the limiting groove  204  effectively fix the fixing part  201  and the second inserting part  208  in a length direction of the bed foot  20 ; and similarly, the first inserting part  201  and the second inserting part  208  are connected and fixed to be capable of improving stability of the bed foot  20 . 
     Referring to  FIG. 8 , clamping grooves  206  are opened in surfaces of the limiting blocks  205  and match with the thickness of the embedding parts  203 , and edge portions of the limiting grooves  204  are inserted into the clamping grooves  206 ; therefore, when the limiting blocks  205  enter the limiting grooves  204 , portions, located at edges of the limiting grooves  204 , of the embedding parts  203  of the limiting grooves  204  are also inserted into the clamping grooves  206  such that the limiting blocks  205  can further radially fix the fixing part  201  and the second inserting part  208 , and the first inserting part  202  and the second inserting part  208  while matching with the embedding parts  203  so as to improve the stability of the bed foot  20 . 
     Referring to  FIG. 6 , inclined guide surfaces  207  are arranged on two sides of an opening of each limiting groove  204 . Due to such arrangement, when the limiting blocks  205  enters the limiting grooves  204  through the openings of the limiting grooves  204 , the two limiting blocks  205  are respectively located in the fixing part  201  and the second inserting part  208  and cannot be directly seen, so the inclination state of the guide surfaces  207  is more beneficial to help the limiting blocks  205  to enter the guide grooves  204 , thereby improving convenience of folding and unfolding operations of the bed body  10 . 
     In the embodiment, the fixing part  201 , the first inserting part  202  and the second inserting part  208  have the same outer diameter, and an outer diameter difference between the embedding part  203  and the first inserting part  202  is equal to the thickness of the fixing part  201 . Due to such arrangement, after the bed foot  20  is assembled, the appearance of the bed foot  20  is smooth and beautiful; secondly, surfaces of the two embedding parts  203  are respectively in contact with an inner wall of the second inserting part  208  and an inner wall of the fixing part  201  such that the whole stability of the bed foot  20  is better; furthermore, during machining, the second inserting part  208 , the fixing part  201  and the first inserting part  202  have the same outer diameter so as to facilitate production and processing to a certain extent. 
     In conclusion, the integrated folding bed of the present disclosure reduces the transportation cost in a folding manner, and the folding and unfolding of the bed body  10  are convenient such that the integrated folding bed has high practicability and wide market popularizing prospect.
