Title: Quick detachable slide rail and drawer mounting structure

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to sliding rail technology and more particularly to a quick detachable slide rail and drawer mounting structure for quick connection between a slide rail assembly and a drawer in a detachable manner, prohibiting relative displacement between the drawer and the slide rail assembly. 
     2. Description of the Related Art 
     For connection between a drawer and a slide rail assembly in a cabinet, a connection structure is necessary. When connected, the drawer can be moved with the slide rail assembly in and out of the cabinet. This connection structure has a connection member fastened to a distal end of the slide rail assembly, and a mating connection device affixed to the bottom panel of the drawer and fastened to the connection member. The installation of this prior art connection structure is complicated and not detachable, complicating the installation. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a quick detachable slide rail and drawer mounting structure, which uses a connection member and a mating connection device set for connection to the slide rail assembly and the drawer respectively, allowing the drawer and the slide rail assembly to be conveniently and detachably fastened together without any tools. 
     To achieve this and other objects of the present invention, a quick detachable slide rail and drawer mounting structure comprises a slide rail assembly, a drawer, a connection member and a mating connection device set. The slide rail assembly comprises an inner slide rail and outer slide rail. The outer slide rail is attached onto the inner slide rail and slidable relative to the inner slide rail. The drawer is fastened to the outer slide rail of the slide rail assembly. The connection member comprises a base, and a first toothed rack disposed at one lateral side of the base. The base is affixed to a distal end of the outer slide rail of the slide rail assembly to hold the first toothed rack at one lateral side of the outer slide rail. The mating connection device set comprises a holder block and an abutment member. The holder block comprises a bottom panel, and a second toothed rack disposed at one side of the bottom panel. The abutment member is mounted at a bottom side of the bottom panel and movable in and out of the bottom panel. The holder block is mounted at a bottom wall of the drawer. 
     Thus, when the drawer and the outer slide rail of the slide rail assembly are connected together, the first toothed rack of the connection member is engaged with the second toothed rack of the mating connection device set to prohibit the drawer from longitudinal and sideway displacement, and the abutment member of the mating connection device set is exposed to the outside of the bottom panel and disposed at a bottom side of the base of the connection member to prohibit relative vertical displacement between the drawer and the outer slide rail.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1-8 , a quick detachable slide rail and drawer mounting structure in accordance with the present invention is shown. The quick detachable slide rail and drawer mounting structure comprises a slide rail assembly  1 , a connection member  2 , a mating connection device set  3  and a drawer  4 . 
     The slide rail assembly  1  comprises an inner slide rail  11  and an outer slide rail  12 . The outer slide rail  12  is attached onto the inner slide rail  11  and slidable relative to the inner slide rail  11 . 
     The connection member  2  comprises a base  21 , a first toothed rack  22  disposed at one lateral side relative to the base  21 , a stop block  23  extended from the base  21 , and an insertion groove  24  defined between the stop block  23  and the first toothed rack  22 . The base  21  is affixed to a free end of the outer slide rail  12  of the slide rail assembly  1  to hold the first toothed rack  22  at one lateral side of the outer slide rail  12 . 
     The mating connection device set  3  comprises a holder block  31 , an abutment member  32 , a spring member  33 , a push member  34 , a shock damper  35 , an adjustment screw bolt  36  and a top cover  37 . 
     As illustrated in  FIGS. 2, 4 and 6 , the holder block  31  of the mating connection device set  3  comprises a bottom panel  311 , a mounting plate  317  extended from one end of the bottom panel  311 , a second toothed rack  312  extended from one lateral side of the bottom panel  311  remote from the mounting plate  317 , a receptacle  313  located a bottom side of the bottom panel  311  and defining therein an accommodation chamber  314  and a front opening  315  in communication between the accommodation chamber  314  and the outside of the receptacle  313 . The abutment member  32  has two opposite ends thereof respectively terminating in an abutment end portion  321  and a mounting end portion  322  with two opposing locating grooves  323 . The abutment member  32  is mounted in the accommodation chamber  314  with the abutment end portion  321  extended out of the front opening  315  of the receptacle  313 . The spring member  33  is stopped between the mounting end portion  322  of the abutment member  32  and an inside wall of the accommodation chamber  314 . The push member  34  attached to the outer surface of the receptacle  313 , comprising a pushing portion  341  and a retaining portion  342  located at a bottom side of the pushing portion  341  and engaged with the locating grooves  323  of the abutment member  32  in the accommodation chamber  314 . Thus, the push member  34  can move the abutment member  32  toward the inside of the accommodation chamber  314  to compress the spring member  33  for storing elastic restoring energy. 
     Referring to  FIGS. 3, 5 and 7 , the bottom panel  311  of the mating connection device set  3  further defines a guide groove  316 . The shock damper  35  comprises a displacement portion  351 , a beveled shock damping portion  352  located at a front end of the displacement portion  351 , and a fixed nut  353  located at one lateral side thereof. The displacement portion  351  of the shock damper  35  is supported on a top surface of the bottom panel  311 . The fixed nut  353  is positioned in the guide groove  316 . The adjustment screw bolt  36  is threaded into the fixed nut  353 . The top cover  37  is covered on the top surface of the bottom panel  311  to hold the shock damper  35  and the adjustment screw bolt  36  therein. Thus, the adjustment screw bolt  36  can be rotated to move the displacement portion  351  of the shock damper  35  along the surface of the bottom panel  311 , thereby moving the shock damping portion  352  in or out of the bottom panel  311 . 
     Referring to  FIGS. 6-10 , in application, the mounting plate  317  of the mating connection device set  3  is affixed to a bottom wall of the drawer  4 , and then the drawer  4  is fastened to the outer slide rail  12 , and then the connection member  2  and the mating connection device set  3  are moved toward each other to force the first toothed rack  22  of the connection member  2  into engagement with the second toothed rack  312  of the mating connection device set  3 , securing the drawer  4  positively in place against longitudinal and sideway displacement. At this time, the abutment member  32  of the mating connection device set  3  is exposed to the outside of the bottom panel  311  and positioned in the insertion groove  24  of the connection member  2  to prohibit relative vertical displacement between the drawer  4  and the outer slide rail  12 . When separating the slide rail assembly  1  and the drawer  4 , operate the push member  34  to move the abutment member  32  into the inside of the accommodation chamber  314 , and then lift the drawer  4  to separate the first toothed rack  22  from the second toothed rack  312 . Further, after connection between the drawer  4  and the outer slide rail  12 , the adjustment screw bolt  36  can be rotated to move the shock damping portion  352  of the shock damper  35  out of the bottom panel  311  into engagement in between the drawer  4  and the base  21  of the connection member  2 , adjusting the elevation of the drawer  4  and eliminating the gap between the drawer  4  and the base  21  to reduce shocks.
