Title: Pet buckle

Description:
BACKGROUND OF THE INVENTION 
     The present disclosure relates to a fastener, specifically to a pet buckle. 
     With the development of China&#39;s social economy, people&#39;s quality of life has also been improved, raising family pets—such as pet dog, and pet cat, has become a new way of people&#39;s pastime recreation. In raising pets, it is often needed to take pets out for outdoor activities so as to meet the pet&#39;s activity demands, and meanwhile to cultivate feelings between people and pets. During the pet outdoor activities, a pet buckle is needed to connect the rope and the pet collar, so that the motion range of pets can be controlled. The present pet buckle cannot achieve a reliable connection, and is easy to get accidentally opened, then during the usage of pet buckle, it is easy to happen that the pet collar and rope get separated because of pet traction, and thus people cannot control the pet&#39;s motion range, which may possibly cause pet loss or pet disturbances and other unexpected problem. 
     Thus the present technology need to be improved and optimized.

     DETAILED DESCRIPTION OF THE INVENTION 
     A pet buckle is disclosed herein, for the purpose of further understanding the object, technical solution and effect of the present disclosure. The present disclosure will hereinafter be described in detail with reference to an exemplary embodiment. It should be understood that the specific embodiments described herein are merely illustrative example of the invention and are not intended to limit the invention. 
     The pet buckle provided by the disclosure is mainly used by matching with a pet collar, when the pet buckle is open and the collar is released, the pet may move freely, and the pet can only move under the traction of the owner when the pet buckle locks the pet collar. 
     Referring to  FIGS. 1-3 , the present disclosure provides a pet buckle, including a hook-shaped buckle body  1  and a lock rod  2  which can be opened and closed with respect to the hook-shaped buckle body  1 . The hook-shaped buckle body  1  includes an end portion provided with a connection groove (not shown), and a front end away from the end portion, with an opening  10  formed by the end portion and the front end, and the lock rod  2  includes a first end  2   a  located in the connection groove and hinged to the hook-shaped buckle body  1  through a first rotation shaft  3 , and a second end  2   b  away from the first end  2   a.  A middle part of the lock rod  2  is sheathed by a torsional spring (not shown), so that the lock rod  2  can only rotate toward the inside of the hook-shaped buckle body  1 , the second end of the lock rod  2  can be locked to the front end of the hook-shaped buckle body  1 , and the opening  10  of hook-shaped buckle body  1  thus gets enclosed, and therefore the pet collar can be locked. 
     In the present embodiment, the end portion of the hook-shaped buckle body  1  is further provided with a first anti-trip clip  11  and a second anti-trip clip  12 , the first anti-trip clip  11  is fixed to both ends of the first rotation shaft  3  to rotate synchronously along with the first rotation shaft  3 . The end portion of the hook-shaped buckle body  1  is also provided with a second rotation shaft  4 , and the second anti-trip clip  12  is fixed to both ends of the second rotation shaft  4  to rotate synchronously along with the second rotation shaft  4 . Herein the first anti-trip  11  and the second anti-trip  12  are respectively located on two sides of the end portion of the hook-shaped buckle body  1 , and a stepped portion  111  is formed on the inside of the first anti-trip clip  11 , while an anti-trip portion  121  engaged with the stepped portion  111  is accordingly formed on the inside of the second anti-trip clip  12 . The end portion of the second anti-trip clip  12  is spaced apart from the end portion of the hook-shaped buckle body  1  by a predetermined distance, so that the second anti-trip clip  12  may rotate within a preset angle range. 
     In the present disclosure, with the first anti-trip clip  11  and the second anti-trip clip  12  provided at the end portion of the hook-shaped buckle body  1 , when the pet buckle is locked, the stepped portion  111  of the first anti-trip clip  11  engaged and fixed with the anti-trip portion  121  of the second anti-trip clip  12 , so that the lock rod  2  cannot rotate to open the pet buckle, thereby improving the reliability of the pet buckle. During unlocking the buckle, it is only needed to simply press the end portion of the second anti-trip clip  12  to drive the second anti-trip clip  12  to rotate outward, to release the stepped portion  111 , and the lock rod  2  can then be pressed to move towards the inside of the hook-shaped buckle body  1 , thus further to release the pet collar. When the pet buckle is being locked, after the lock rod is reset, the anti-trip portion  121  gets rotated towards the inside of the hook-shaped buckle body  1 , so that the anti-trip portion  121  gets engaged with the step portion  111 , to realize a function of preventing occasionally unlocking. 
     Still referring to  FIGS. 1 and 2 , in the pet buckle of the present disclosure, the second end of the lock rod  2  is provided with a first groove  21  and a first projection  22 , and the front end of the hook-shaped buckle body  1  is provided with a second projection  14  fitted to the first groove  21  and a second recess  13  fitted to the first projection  22 . When the pet buckle is being locking, the first recess  21  engages with the second projection  14 , and the first protrusion  22  engages with the second recess  13 , to prevent the lock rod  2  from rotating toward the outside of the hook-shaped buckle body  1 . 
     Further, the pet buckle of the present disclosure further includes a link ring  5 , the link ring  5  is provided with a through hole  8 , the bottom of the hook-shaped buckle body  1  is provided with a connecting shaft  7 , and a boss  6  is formed on an end of the connecting shaft  7 . The link ring  5  is hung on the connecting shaft  7  through the through hole  8  and is located between the boss  6  and the end of the connecting shaft  7 . In the present embodiment, the diameter of the connecting shaft  7  is smaller than the diameter of the through hole  8 , so that the connecting shaft  7  can freely rotate in the through hole  8 , thereby improving the comfort and avoiding the twisting of the traction rope, when pulling the pet. 
     Furthermore, the link ring  5  is in a “B” shape in such a manner that the traction rope  9  and the belt  9 ′can be locked on the link ring  5 . 
     As described above, according to the present disclosure, with the first anti-trip clip and the second anti-trip clip formed at the end portion of the hook-shaped buckle body, when the pet buckle is locked, the stepped portion of the first anti-trip clip gets engaged and fixed with the anti-trip portion of the second anti-trip clip, so that the lock rod cannot rotate to open the pet buckle, thereby improving the reliability of the pet buckle. During unlocking the buckle, it is only needed to simply press the end portion of the second anti-trip clip to drive the second anti-trip clip to rotate outward, to release the stepped portion, and the lock rod can then be pressed to move towards the inside of the hook-shaped buckle body  1 , thus further to release the pet collar. When the pet buckle is being locked, after the lock rod is reset, the anti-trip portion gets rotated towards the inside of the hook-shaped buckle body, so that the anti-trip portion gets engaged with the step portion, to realize a function of preventing occasionally unlocking. In addition, the present invention involves advantages of a simple structure and convenient operation. 
     It is to be understood by those skilled in the art that many equivalents or variations may be made in accordance with the technical solutions of the invention and the inventive concept thereof, and all such equivalents or variations should be within the scope of the claims appended hereto.
