[0002] At present, on the security door and lock hardware market, the side locks widely used in various security doors basically adopt an integrated lock bolt stroke sliding plate structure that pushes and pulls the bolts out and retracts the bolts in parallel in the upper and lower directions, that is, the tail push plate and the lock bolt stroke sliding plate that are installed in conjunction with the top and bottom rod sockets are integrally formed on a stamping part. When such a side lock is installed on the door body and installed in conjunction with the top and bottom rods, its tail push plate has no adjustability, and the top and bottom rods are usually very slender round steel bars with a square punched out with a rectangular hole or a round hole in the middle. This manufacturing process and turnover process can easily cause it to bend and deform. When installed on the door leaf, there will be varying degrees of warping, so that the side lock hole and the side lock tail push plate will have a large offset and run out of position when docking and installing. After the side lock is installed, interference, squeezing, scratching, obstruction, or jamming will occur during the push and pull of the side lock bolt stroke, resulting in the side lock bolt not being able to be retracted or locked in place, and finally causing the door leaf to fail to open normally or fail to be safely locked in place.

[0044] Example

[0045] Figure 1 , Figure 2 It is an exploded isometric view and a partially cutaway isometric view of the side lock of the tail push piece capable of adaptively offsetting and adjusting the position in this embodiment. Figure 3 , Figure 41 is an exploded isometric view and an isometric view of the lock bolt travel slide push plate assembly in this embodiment. Combining the four figures, it can be seen that:

[0046] In this embodiment, the side lock with a tail push piece that can adaptively offset and adjust the position is composed of a side lock panel 5, a panel screw 10, a nut 4, a side lock cover 6, a side lock shell 9, a lock tail push piece tension spring, a side lock bolt assembly, a lock bolt travel slide plate assembly, a side lock bolt slide pin sleeve 2 and a lock bolt reset tension spring 11.

[0047] In this embodiment, the side lock panel 5 is installed on the side lock shell 9 by the panel screws 10 and the nuts 4. The side and tail ends of the side lock shell 9 each have a large slot at the end to assist the top and bottom rods in correcting, aligning, and limiting the position, and allowing a tail push piece of the top and bottom rods to offset the deviation within the adjustment range. The side lock cover 6 is installed on the side lock shell 9 by means of the two end buckles and the two end slots of the tail. The two end slots of the tail lock the two end sides of the side lock shell 9.

[0048] The side lock bolt assembly consists of a lock bolt plate 13, a side lock bolt head 3 riveted on the middle surface of the lock bolt plate 13 with an axial hole, and a lock bolt slide pin 12 on the folded edge of the small flange on the bottom side. The side lock bolt head 3 is gap-nested in the lock bolt hole of the side lock panel 5, and the side lock bolt slide pin sleeve 2 is placed together with the lock bolt slide pin 12 in the inclined travel slide groove in the middle of the lock bolt travel slide bottom plate 7 to realize the lock bolt travel slide plate assembly pushing the lock bolt assembly to retract and extend the bolt.

[0049] The lock bolt travel slide plate assembly is composed of a lock bolt travel slide plate assembly that was originally formed integrally on a stamping part on an ordinary side lock, which is divided into two and disassembled into a lock bolt travel slide plate 7, a tail push plate 8 and a tail push plate tension spring that are independent of each other and nested and connected with each other. The lock bolt travel slide plate 7 is installed on the bottom plate of the side lock shell 9 and is limited and slidably guided by the slots close to the bottom of the shell on both ends of the side lock shell 9. The middle part is an inclined travel slide groove, and the upper end has a narrow high folded flange structure lock bolt reset tension spring hanging platform 15 for hanging a lock bolt reset tension spring 11, and a 90° bent edge flange on the side near the middle. This flange has a tail push plate tension spring hanging platform 18 for hanging a tail push plate tension spring near the middle end, and a tail push plate connecting hole 14 on the other end that is gap-nested and connected with the tail push plate dry-shaped boss 16 of the tail push plate 8; the tail push plate 8 is a structure in the shape of an L-shaped main side. The tail push piece 8 in the component and the mechanism can be nested in the tail push piece connecting hole 14 of the lock bolt stroke sliding plate with a gap, and the tail push piece stem-shaped boss 16 on the tail push piece connecting hole 14 of the lock bolt stroke sliding plate is provided with a tail push piece self-limiting convex beak 17 near the root of the tail folding edge, which is used to buckle and block the 90° bent edge line flange on the middle side of the lock bolt stroke sliding bottom plate 7 to limit it in the horizontal direction. The two end circles of the tail push piece tension spring are hung and buckled on the tail push piece tension spring hanging platform 18 of the lock bolt stroke sliding bottom plate 7 and the tail push piece stem-shaped boss 16 of the tail push piece 8. The tail push piece 8 in the component and the mechanism can be gap-nested in the tail push piece stem-shaped boss 16 on the tail push piece connecting hole 14 of the lock bolt stroke sliding plate as a rotating fulcrum to swing at an angle and slide back and forth on this long strip hole in a certain interval size in the length direction; one end of the side lock resetting tension spring is hung on the side hanging platform at the end of the side lock shell 9, and the other end is hung on the lock bolt reset tension spring hanging platform 15 of the lock bolt stroke sliding bottom plate 7.

[0050] The core point of this embodiment to solve the above-mentioned problem is that the tail push piece 8 can be freely deflected upward at a large angle on both sides between the side lock tail shell and the cover, and can be elastically pushed in the up and down directions to adjust a size to achieve a certain size range of the tail push piece 8 in the installation and matching position with the hole of the sky and the earth rod, that is, the sky and the earth rod has a certain degree of deflection, tilting, or the size displacement in the up and down, left and right directions will not affect the normal working condition of the side lock, that is, it overcomes the problems of side lock squeezing, scratching, blocking, or failure to retract in place that may occur in ordinary side locks. At the same time, the side tails of the two ends of the side lock shell 9 each have a large notch to assist the sky and earth rod in correcting, regulating, and limiting, and allow the tail push piece 8 of the sky and earth rod to deviate within the adjustment range. The large or abnormal deflection, tilting, or the size displacement in the up and down, left and right directions of the sky and the earth rod relative to the side lock can be clearly detected, and the sky and the earth rod can be assisted in correcting, regulating, and limiting, so as to overcome the above-mentioned problems to the greatest extent.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
