[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0018] The following will further describe the present utility model with reference to the accompanying drawings of the specification.

[0019] The present utility model provides the following technical solutions:

[0020] As attached Figures 1-3As shown, the utility model discloses a door lock structure, which includes two symmetrically arranged door handles 1 and a handle seat 2. The door handle 1 is connected to the corresponding handle seat 2. An installation groove 3 is arranged on the end face of the handle seat 2 away from the door handle 1. A reinforcing part 4 protrudes from the groove wall of the installation groove 3. The reinforcing part 4 divides the installation groove 3 into an upper groove part 5 and a lower groove part 6. A positioning reinforcing end 7 and a transmission reinforcing end 8 protrude from the groove wall of the lower groove part 6. A positioning hole 9 is opened on the positioning reinforcing end 7, and a transmission hole 10 is opened on the transmission reinforcing end 8. Specifically, in this design, by arranging the positioning reinforcing end 7 and the transmission reinforcing end 8 on the groove wall of the lower groove part 6, it can act as a reinforcing rib, effectively improving the stability and durability of the door lock structure. The positioning hole 9 on the positioning reinforcing end 7 is used to install the handle seat 2 on the door body, and the transmission hole 10 on the transmission reinforcing end 8 is used to connect the square shaft, so that the rotation of the door handle 1 can be smoothly transmitted to the lock core to realize the opening and closing function of the door lock. The setting of the reinforcing part 4 can further improve the strength of the installation groove 3 to ensure that it will not be deformed due to uneven force during long-term use. In addition, the existence of the reinforcing part 4 also helps to disperse the stress concentration when the handle seat 2 is subjected to external force impact, thereby prolonging the service life of the door lock.

[0021] Furthermore, the positioning reinforcing end 7 protrudes from the groove wall of the lower groove part 6 on one side of the reinforcing part 4 and the opposite groove wall. The transmission reinforcing end 8 protrudes in a ring structure at the center position of the lower groove part 6. A square shaft transmission part 11 is arranged on each door handle 1. One end of the square shaft transmission part 11 extends into the corresponding transmission hole 10 to be connected to the corresponding handle seat 2. Specifically, in this embodiment, by arranging the positioning reinforcing end 7 on the two groove walls of the lower groove part 6, it can ensure that the installation of the handle seat 2 on the door body is more stable and avoid loosening caused by long-term use. At the same time, the ring structure design of the transmission reinforcing end 8 makes the force on the transmission hole 10 more uniform, thereby improving the transmission efficiency and reducing wear. The cooperation of the square shaft transmission part 11 and the transmission hole 10 ensures the precise transmission between the rotation of the door handle 1 and the opening and closing action of the lock core.

[0022] Furthermore, the two groove walls of the lower groove part 6 away from the positioning reinforcing end 7 have two arc surfaces 12.

[0023] Further, a transmission assembly is disposed in the lower groove portion 6. The transmission assembly includes a rotation limiting member 13 and a spring 14 sleeved on the transmission strengthening end 8. One end of the square shaft transmission member 11 passes through the transmission strengthening end 8 and extends into the interior of the lower groove portion 6. The rotation limiting member 13 is sleeved on the end of the square shaft transmission member 11 extending into the lower groove portion 6, and the rotation limiting member 13 presses the spring 14. Specifically, in this embodiment, the rotation limiting member 13 in the transmission assembly cooperates with the square shaft transmission member 11, which can ensure that the handle 1 has a clear limit point during rotation and prevent damage caused by excessive rotation. The rotation limiting member 13 is sleeved on the end of the square shaft transmission member 11 extending into the lower groove portion 6. By pressing the spring 14, the rotation limiting member 13 can flexibly cooperate with the square shaft transmission member 11 when the handle 1 rotates, realizing an accurate limiting function.

[0024] Further, the rotation limiting member 13 is arranged in an annular structure. A limiting connection end 15 protrudes from the inner ring side of the rotation limiting member 13. A limiting connection groove 16 corresponding to the limiting connection end 15 is formed on the square shaft transmission member 11. The limiting connection end 15 extends into the limiting connection groove 16 to connect with the square shaft transmission member 11. Specifically, in this embodiment, the annular structure design of the rotation limiting member 13 can not only provide uniform limiting force, but also the protruding limiting connection end 15 on its inner ring side cooperates with the limiting connection groove 16 on the square shaft transmission member 11, ensuring a stable connection between the rotation limiting member 13 and the square shaft transmission member 11. The limiting connection end 15 extends into the limiting connection groove 16, enabling the rotation limiting member 13 to closely cooperate with the square shaft transmission member 11 when the handle 1 rotates, thereby realizing an accurate limiting function.

[0025] Further, the rotation limiting member 13 has two limiting ends 17 arranged on the same side. Rotating the rotation limiting member 13 drives the limiting ends 17 to be in limiting contact with the groove wall of the lower groove portion 6. Specifically, in this embodiment, the protruding part between the limiting end 17 and the arc surface 12 is in limiting contact, thereby realizing accurate control of the rotation angle of the handle 1. By the limiting ends 17 of the rotation limiting member 13 being in contact with the arc surface 12 of the lower groove portion 6, the handle 1 can be effectively prevented from rotating excessively, ensuring that the door lock remains in an appropriate position during the opening and closing process and avoiding damage or noise caused by excessive rotation.

[0026] Furthermore, an inner concave limiting groove 18 is formed at the edge part of the handle seat 2 close to the installation groove 3. Specifically, in order to facilitate the positioning of the handle seat 2 during the installation on the door body, the arrangement of the limiting groove 18 can ensure that the installation position of the handle seat 2 on the door body is more accurate. The inner concave structure of the limiting groove 18 enables the handle seat 2 to closely cooperate with the corresponding convex part on the door body during the installation process, thus avoiding the dislocation phenomenon during installation. In addition, the existence of the limiting groove 18 also helps to improve the connection strength between the handle seat 2 and the door body, ensuring that it will not become loose due to vibration or external force during long-term use.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
