[0016] 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.

[0017] As shown in the attached figure, this utility model discloses a swing door lock installation structure, including two handles 1 and a base 2. The two bases 2 are connected to each other by connecting screws 3. The connection between the two handles 1 by connecting screws 3 is an existing structure. Based on this, each of the two bases 2 includes a transmission block 21, which rotates on the base 2. The end face of the handle 1 has a recess corresponding to the transmission block 21 for accommodating the transmission block 21. The two sides of the transmission blocks 21 that are far apart from each other are provided with screw holes 210. Each of the two handles 1 is provided with a through hole 10 corresponding to the screw hole 210. The through hole 10 is through which a screw connected to the screw hole 210 passes. The two transmission blocks 21 are connected by a square shaft 4. The screw passes through the front of the handle 1 and through the through hole 10, and then connects to the corresponding screw hole 210, so as to realize the fixed connection between the handle 1 and the corresponding transmission block 21. The handle 1 drives the transmission block 21 to rotate, and then the square shaft 4 connected to the transmission block 21 drives the lock cylinder to move.

[0018] This utility model discloses the principle and effect of a swing door lock installation structure. By setting the transmission block 21 and handle 1 as separate structures, with the transmission block 21 set on the base 2, the base 2 and transmission block 21 can be installed onto the door leaf during factory production, and then the handle 1 can be installed on-site. The handle 1 and transmission block 21 are connected by screws passing through the through hole 10 and connecting to the screw hole 210, facilitating installation, improving on-site installation efficiency, and making it convenient to replace the handle 1 later. It should be noted that existing designs have the handle 1 and transmission block 21 as an integrated structure. To protect the handle 1, the swing door lock and door leaf are transported separately during the factory to prevent damage to the handle 1 on the door leaf during transportation. The handle 1 is then installed onto the door leaf on-site. This technical solution, however, allows the base 2 and transmission block 21 to be installed onto the door leaf before leaving the factory, and the handle 1 can be directly installed on-site, facilitating alignment and improving efficiency.

[0019] Specifically, the base 2 has a silicone pad 209 on the side facing each other, which can better protect the door surface and prevent the door surface from directly contacting the door lock. At the same time, the silicone pad 209 is pressed firmly onto the door by the screws, which can more stably install the door lock.

[0020] Specifically, each of the two transmission blocks 21 has a square hole 200 for inserting the square shaft 4 on its facing side. A spring piece 202 is provided inside the square hole 200 to tightly abut against the square shaft 4, preventing gaps and loosening during transmission. It should be understood that existing square shafts 4 are directly inserted into the square hole 200. Due to manufacturing errors or other reasons, a certain gap may exist between the square hole 200 and the square shaft 4, resulting in a certain amount of play when the handle 1 drives the square shaft 4. This play may also cause the handle 1 to fail to maintain a parallel state, potentially leading to... If the handle 1 droops, a spring piece 202 is installed in the square hole 200. The spring piece 202 can be used to press against the square shaft 4 to fill the gap between the square shaft 4 and the square hole 200, thereby reducing the gap when the handle 1 drives the square shaft 4 and ensuring that the handle 1 will not droop. The spring piece 202 is curved in an arc shape. One end of the spring piece 202 is fixedly connected to the transmission block 21, and the middle part of the spring piece 202 is curved and protrudes towards the center of the square hole 200. Alternatively, the spring piece 202 can be placed directly in the square hole 200 and the middle part of the spring piece 202 is bent towards the center of the square hole 200.

[0021] Specifically, the handle 1 has an opening on the front, and a panel 11 is provided in the opening. A brush strip 112 is provided on the outer side of the panel 11, and the brush strip 112 abuts against the opening. The handle 1 has a hollow structure, which facilitates the installation of the handle 1 and the transmission block 21. During installation, the handle 1 is fitted onto the transmission block 21, and a screw is inserted through the opening on the front to connect the through hole 10 and the screw hole 210. Finally, a panel 11 is provided to cover the opening of the handle 1. The panel 11 uses the outer brush strip 112 to hold the inner side wall of the opening of the handle 1, which can eliminate the gap between the panel 11 and the handle 1 and achieve the effect of quiet opening and closing of the door.

[0022] Specifically, the opening is provided with a socket 101 for installing a key. The socket 101 is rotatably connected to the handle 1. The tail end of the socket 101 is provided with a pivot, which is rotatably connected to the handle 1, so that the socket 101 can rotate with the tail end as the pivot point. The head end of the socket 101 is provided with a socket hole for inserting a key. The user can insert the key into the socket 101 and cover the panel 11 to hide the key. The key can be taken out for use in an emergency. The socket 101 is only provided in the handle 1 at the outdoor end for emergency use.

[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
