[0020] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0021] The door lock spring support assembly includes a spring clamping insert 2 and a locking seat 1. The spring clamping insert 2 is used to clamp the spring member 3 and compress the spring member 3. The locking seat 1 is used to place and position the lock body 4. The locking seat 1 includes a horizontal seat plate 11, a vertical seat plate 12, and a locking pin 13. The lower part of the vertical seat plate 12 is fixedly connected to the end of the horizontal seat plate 11. The lower part of the locking pin 13 is assembled with the horizontal seat plate 11. The upper parts of the vertical seat plate 12 and the upper parts of the locking pin 13 are respectively positioned in a direction away from the horizontal seat plate 11. The lock body 4 is arranged in a vertically extending manner. The horizontal seat plate 11 is used to place the lock body 4, and the vertical seat plate 12 is arranged to be horizontally abutting the lock body 4. The fixed lock pin 13 is used to pass through and position the lock body 4. The horizontal seat plate 11 has a horizontal plate groove 14, which is arranged to be recessed downwards. The lock body 4 has a lock protrusion 44, which is arranged to be protruding. The horizontal plate groove 14 is used to provide for the lock protrusion to be embedded, and the horizontal plate groove 14 is used to position the lock protrusion 44. Along the horizontal direction, the fixed lock pin 13 and the horizontal plate groove 14 are arranged in a corresponding manner at intervals.

[0022] In the above-mentioned door lock spring support assembly device, during assembly, the lock body 4 is first placed on the fixed lock seat 1. At this time, the horizontal seat plate 11 and the vertical seat plate 12 simultaneously abut and position the lock body 4. The fixed lock pin 13 passes through the lock body 4, and the fixed lock pin 13 achieves the positioning of the lock body 4. The lock protrusion 44 is embedded in the horizontal plate groove 14, and the vertical seat plate 12 plays a positioning role for the lock body 4, improving the loading accuracy of the lock body 4. In this way, along the length direction of the lock body 4, the fixed lock pin 13 and the horizontal plate groove 14 cooperate to achieve double positioning of the lock body 4 and limit the offset, improving the positioning effect of the lock body 4. Then, the compressed spring 3 is installed onto the lock body 4 through the spring clip 2. The structure is simple, easy to operate, and low in cost.

[0023] The locking seat 1 includes a seat clamping plate 15 and a pressure applying member 16. The seat clamping plate 15 and the longitudinal seat plate 12 are arranged at intervals. The two ends of the pressure applying member 16 are respectively equipped with the seat clamping plate 15 and the transverse seat plate 11. The pressure applying member 16 is used to apply a force to the seat clamping plate 15 in the direction of the longitudinal seat plate 12. The lock body 4 includes a lock plate. The seat clamping plate 15 is used to lay flat against the lock plate, and the longitudinal seat plate 12 and the seat clamping plate 15 are used to clamp and position the lock body 4.

[0024] In this way, the seat clamp 15 applies pressure to the lock plate, and together with the longitudinal seat plate 12, it clamps the lock body 4, thereby enhancing the fixing effect of the lock body 4.

[0025] The fixed locking pin 13 is movably assembled with the horizontal seat plate 11. The fixed locking seat 1 includes a pin cylinder, and the fixed locking pin 13 and the pin cylinder are arranged in an upper and lower docking arrangement. The pin cylinder is used to drive the fixed locking pin 13 to move relative to the horizontal seat plate 11 in the vertical direction.

[0026] In this way, after assembly, the fixed locking pin 13 is driven by the cylinder to move vertically downward relative to the horizontal seat plate 11 until the fixed locking pin 13 is disengaged from the lock body 4, which facilitates the removal of the lock body 4 and avoids deformation and damage to the lock body 4 caused by manual removal, thereby improving the pass rate of the lock body 4.

[0027] The locking seat 1 is installed on the machining table, and the cylinder is installed on the machining table to facilitate the control of the locking cylinder 13 by the cylinder.

[0028] The lock body 4 includes a lock assembly 41, a bottom lock shell 42, and a top lock shell 43. The bottom lock shell 42 and the top lock shell 43 are assembled together to form a lock cavity. The lock assembly 41 is assembled into the lock cavity. The horizontal seat plate 11 is used to place the bottom lock shell 42. The top lock shell 43 includes an outer cover plate 431. The outer cover plate 431 is arranged correspondingly to the vertical seat plate 12. When the outer cover plate 431 abuts against the vertical seat plate 12, the bottom lock shell 42 and the top lock shell 43 are assembled together.

[0029] In this way, when the bottom lock shell 42 and the top lock shell 43 are assembled, the outer cover plate 431 and the longitudinal seat plate 12 cooperate to position and reference the bottom lock shell 42 and the top lock shell 43, avoid excessive pressing pressure, and ensure the assembly of the bottom lock shell 42 and the top lock shell 43.

[0030] The bottom lock housing 42 has a block housing hole and a pillar housing hole, which are arranged in a through manner. The block housing hole and the pillar housing hole are respectively arranged in a corresponding manner with the horizontal plate groove 14. The lock assembly 41 includes a fixed lock plate and a locking pin 45. The locking pin 45 is assembled to the pillar housing hole, and the fixed lock plate is assembled to the block housing hole. The end of the fixed lock plate forms a lock protrusion 44. Under the action of the horizontal plate groove 14, the lock body 4 is arranged horizontally, avoiding collisions caused by the loading of the lock body 4.

[0031] The locking pin 13 is arranged in a rectangular shape and has four cylindrical surfaces, which are simultaneously arranged to lie flat and abut against the lock body 4. This improves the cooperation between the locking pin 13 and the lock body 4 and enhances the positioning effect of the locking pin 13.

[0032] When installing the spring component 3, first place the bottom lock housing 42 on the horizontal seat plate 11, with the end of the bottom lock housing 42 in contact with the vertical seat plate 12. Then assemble the lock assembly 41 onto the bottom lock housing 42. At this time, the bottom lock housing 42 has a reserved spring groove. Then, install the compressed spring component 3 into the spring groove through the spring clip 2. Finally, close the bottom lock housing 42 with the cover lock housing 43.

[0033] Example 1 of pressure-applying component 16: The pressure element 16 includes a pressure spring, the two ends of which are respectively mated to the seat clamp plate 15 and the cross seat plate 11. The pressure spring is used to cause the seat clamp plate 15 to lay flat against the locking plate. When the cross seat plate 11 moves in a direction away from the cross seat plate 11, the pressure spring is gradually tensioned.

[0034] In this way, the pressure spring applies elastic force to the seat clamp 15 to apply pressure to the lock plate, thus satisfying the clamping of the lock body 4.

[0035] Example 2 of pressure-applying component 16: The pressure-applying component 16 includes a cylinder component mounted on the cross seat plate 11, and the cylinder component has a cylinder shaft that is extended or retracted, and the cylinder shaft is mated to the seat clamp plate 15. In this way, the seat clamping plate 15 is driven by the cylinder shaft to move towards the horizontal seat plate 11, so that the seat clamping plate 15 applies pressure to the lock plate and satisfies the clamping of the lock body 4.

[0036] The longitudinal seat plate 12 is provided with a pressure sensor. The pressure sensor has a detection surface. The longitudinal seat plate 12 has a longitudinal seat surface for abutting the lock body 4. The pressure sensor is embedded in the longitudinal seat plate 12, and the detection surface is flush with the longitudinal seat surface. The detection surface is used to abut the lock body 4, and the pressure sensor is used to detect the force applied to the lock body 4 by the pressure member 16.

[0037] This prevents the seat plate 15 from applying excessive pressure to the lock plate, thus protecting the lock body 4.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
