[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a circuit breaker connector injection molding accessory that is easy to install and disassemble, including a connector body 1. Connecting arms 2 are provided at both the upper and lower ends of the connector body 1. Several locking blocks 3 are evenly distributed on the outer side of the connecting arms 2 for fitting into corresponding slots on the circuit breaker. Deformable elastic arches 5 are provided on the outer walls of both the upper and lower ends of the locking blocks 3, and retractable elastic abutments 6 are provided on both sides of the locking blocks 3. The elastic arches 5 and elastic abutments 6 together constitute a quick-release mechanism for the circuit breaker. Furthermore, the inner end of each connecting arm 2 is provided with a pull-out member 7 that extends movably into the connector body 1. This structure allows the connecting arms 2 to extend and retract within the connector body 1 via the pull-out member 7, pre-adjusting them to a position suitable for circuit breaker installation. Furthermore, when installing or removing the circuit breaker, the operator only needs to align the locking block 3 on the connecting arm 2 with the corresponding slot on the circuit breaker. The elastic arch 5 deforms under external force, allowing the locking block 3 to smoothly embed into the slot of the circuit breaker. At the same time, the elastic abutments 6 on both sides of the locking block 3 are compressed as the locking block 3 enters and automatically pop out after reaching the designated position, ensuring that the locking block 3 is firmly locked on the circuit breaker. This utilizes the linkage between the elastic arch 5 and the elastic abutments 6, allowing installation to be completed quickly without additional tools, greatly facilitating the user's operation. Therefore, this structure solves the problem of complex assembly requiring tools in traditional connecting seats in the prior art, significantly reducing the time cost of installation and disassembly. Simultaneously, due to the connection... The arm 2 can be adjusted in position via the pull-out piece 7, increasing flexibility and allowing the accessory to adapt to different circuit breaker specifications, thereby improving compatibility. This design also overcomes the difficulty of effective installation and disassembly in narrow spaces, improving maintenance efficiency, enhancing operational convenience and work efficiency, ultimately reducing overall maintenance costs and expanding the application range. The connecting base body 1 has an internal slot that mates with the pull-out piece 7, and both the upper and lower ends of both sides of the connecting base body 1 are connected with threaded bolts. Furthermore, damping strips are adhered to the outer walls of both sides of the pull-out piece 7. This structure allows the pull-out piece 7 to slide smoothly within the internal slot of the connecting base body 1, enabling position adjustment of the connecting arm 2. When it is necessary to fix the position of the connecting arm 2, the operator can... By tightening the bolts at both ends of the connecting body 1, pressure can be applied to the pull-out component 7 to prevent it from sliding further, ensuring that the connecting arm 2 is stably held in the required adjustment position. The outer wall of the front end of the connecting body 1 is evenly provided with several strip-shaped protrusions 8, and these protrusions 8 form an integral structure with the connecting body 1. This structure increases the friction between the connecting body 1 and the circuit breaker when they come into contact, ensuring a more stable and reliable connection. Furthermore, since the protrusions 8 and the connecting body 1 are integrally formed, this not only enhances the overall strength of the structure but also avoids the risk of loosening or detachment caused by additional components. Both ends of the connecting arm 2 are provided with mounting holes, and reinforcing ribs 4 are welded and fixed to the corners of both ends of the connecting arm 2.The mounting holes at both ends of the connecting arm 2 allow for easy and secure installation of the connecting arm 2 onto the circuit breaker or other supporting structure using bolts or other fasteners. Meanwhile, the reinforcing ribs 4 significantly enhance the strength and structural stability of the connecting arm 2, effectively preventing deformation or damage, especially under external forces or vibrations, and maintaining a stable connection even under heavy loads. The locking block 3 has a through hole that matches the structure of the elastic abutment 6, and the through hole inside the locking block 3 is filled with an elastic block 10. One end of the elastic abutment 6 located inside the through hole of the locking block 3 has an annular limiting block 9. The inner wall of the locking block 3 has an annular limiting groove that matches the structure of the annular limiting block 9. When the two elastic abutments 6 are subjected to force, they will drive the annular limiting block 9 to simultaneously press against the elastic block 10, causing the elastic block 10 to... The elastic abutment 6 undergoes compression deformation, ensuring smooth contraction during its insertion into the circuit breaker slot. Upon reaching the designated position, it automatically pops out due to the restoring force of the elastic block 10, firmly locking onto the circuit breaker. Furthermore, the engagement of the annular limiting block 9 and the annular limiting groove on the internal through-hole of the locking block 3 prevents the elastic abutment 6 from falling out of the through-hole. Both ends of the locking block 3 have strip-shaped grooves on their outer walls, and both ends of the elastic arch 5 are fixedly connected to the inner walls of the strip-shaped grooves on both sides of the locking block 3. As the locking block 3 advances, the elastic arch 5 deforms along the strip-shaped grooves under external force, compressing or stretching to adapt to the shape of the circuit breaker slot, ensuring that the locking block 3 can smoothly enter and fit tightly. When the external force is removed, the elastic arch 5 returns to its original shape, and its elasticity firmly locks the locking block 3 onto the circuit breaker.

[0019] Working principle: When using this easy-to-install and disassemble circuit breaker connector injection fitting, the operator first slides the pull-out piece 7 into the slot inside the connector body 1 to pre-adjust the connecting arm 2 to the appropriate position for the circuit breaker installation. Then, the locking block 3 on the connecting arm 2 is aligned with the corresponding slot on the circuit breaker. During the pushing process, the elastic arch 5 on the outer walls of the upper and lower ends of the locking block 3 deforms along the strip groove to adapt to the shape of the circuit breaker slot, allowing the locking block 3 to be smoothly inserted. At the same time, the elastic abutment 6 is compressed as the locking block 3 enters. When the elastic abutment 6 is compressed, it drives the annular limiting block 9 to move together. When the elastic block 10 is pressed, it is compressed and deformed. After reaching the designated position, it automatically pops out, and the elastic abutment 6 is locked in the slot on the circuit breaker. After the initial positioning is completed, the operator tightens the abutment bolts at both ends of the connecting seat body 1 and applies pressure to the pull-out part 7 to fix the position of the connecting arm 2. Then, the connecting arm 2 is firmly installed on the circuit breaker or other support structure through the mounting holes at both ends of the connecting arm 2 using bolts or other fasteners. In the whole process, through the close cooperation of each part, quick installation and disassembly without tools are realized, thereby completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
