Therefore, this utility model proposes a door latch seat that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A door latch seat that is easy to install includes a latch seat body disposed on one side of a panel. The panel has an installation hole, and two sliders are movably connected inside the installation hole. A fixing plate is fixedly connected to one side of each slider. The fixing plate and the corresponding slider have through threaded holes. Fastening bolts are inserted into both ends of the latch seat body, and the fastening bolts are threadedly connected to the corresponding threaded holes. A connecting plate is fixedly connected to one side of each slider. One end of the connecting plate passes through the installation hole and is movably connected to a rotating pressure plate through a rotating assembly.

[0007] Furthermore, the bottom of the rotating pressure plate is integrally formed with a protrusion, and both ends of the buckle seat body are fixedly connected with reinforcing ribs, and the protrusion can contact the reinforcing ribs at the corresponding positions.

[0008] Furthermore, the rotating assembly includes a rotating shaft, which is fixed to one side of the rotating pressure plate by bolts. One end of the connecting plate is provided with a clearance groove, and the rotating shaft is located in the clearance groove and rotatably connected to the connecting plate.

[0009] Furthermore, an elastic pad is fixedly connected to one side of the rotating pressure plate, and the elastic pad is in contact with the nut on the fastening bolt.

[0010] Furthermore, an anti-slip pad is fixedly connected to one side of the fixed pressure plate, and the anti-slip pad is in contact with the panel.

[0011] Furthermore, the mounting hole is a rectangular hole.

[0012] Furthermore, the cross-section of the rotating shaft is a T-shaped structure.

[0013] Furthermore, the slider is a cube.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model not only facilitates the installation and disassembly of the latch seat body and the panel, but also allows for adjustment of the installation position of the latch seat body through the rectangular mounting holes, making it convenient to use and improving the flexibility of the device.

[0016] 2. This utility model can not only further restrict the position of the fastening bolt by rotating the pressure plate, thus preventing the fastening bolt from easily reversing and coming out of the threaded hole during long-term use, but also reduce the damage to the structure caused by the rigid collision between the fastening bolt and the rotating pressure plate by the elastic pad, thereby improving the effectiveness of the device.

[0017] 3. By using the combination of reinforcing ribs and protrusions, this utility model can position and limit the rotation of the rotating pressure plate, while also supporting the position of the rotating pressure plate. This makes it easy to quickly determine the position of the rotating pressure plate in contact with the fastening bolts, thus improving the convenience of operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A door latch seat that is easy to install includes a latch seat body 12 disposed on one side of a panel 1. The panel 1 has a mounting hole 2, which is rectangular, allowing the latch seat body 12 to move along its length, thus adjusting its installation position. Two cubic sliders 3 are slidably connected inside the mounting hole 2. A fixing plate 4 is bolted to one side of each slider 3. The fixing plate 4 and the corresponding slider 3 have through threaded holes 5. Fastening bolts 13 are inserted into both ends of the latch seat body 12, and these bolts are threaded into the corresponding threaded holes 5. An anti-slip pad 11 is adhered to one side of the fixing plate 4 and contacts the panel 1. The anti-slip pad 11 increases the friction between the fixing plate 4 and the panel 1.

[0026] It should be noted that a connecting plate 6 is fixed to one side of the slider 3 by bolts. One end of the connecting plate 6 passes through the mounting hole 2 and is rotatably connected to a rotating pressure plate 7 via a rotating assembly. The rotating pressure plate 7 can further restrict the position of the fastening bolt 13, preventing the fastening bolt 13 from easily reversing and dislodging from the threaded hole 5 during long-term use. The rotating assembly includes a rotating shaft 8 with a T-shaped cross-section. The rotating shaft 8 is fixed to one side of the rotating pressure plate 7 by bolts. One end of the connecting plate 6 has a relief groove, and the rotating shaft 8 is located in the relief groove and rotatably connected to the connecting plate 6. The latch body 12 is aligned with the threaded hole 5 on the slider 3, and then the fastening bolt 13 is pre-tightened into the corresponding threaded hole 5 to facilitate the alignment of the latch body 12 with the two sliders 3 and determine the required installation position. Then, continue to rotate the fastening bolt 13 so that it passes through the threaded hole 5. At this time, the fixing plate 4 is pressed against the panel 1 through the anti-slip pad 11, thereby fixing the buckle seat body 12 onto the panel 1. The bottom of the rotating pressure plate 7 is integrally formed with a protrusion 10. Both ends of the buckle seat body 12 are fixed with reinforcing ribs 14 by bolts, and the protrusion 10 can contact the corresponding reinforcing ribs 14. Through the cooperation of the reinforcing ribs 14 and the protrusion 10, the rotation position of the rotating pressure plate 7 is restricted. An elastic pad 9 is bonded to one side of the rotating pressure plate 7, and the elastic pad 9 is in contact with the nut on the fastening bolt 13. The elastic pad 9 can absorb impact energy through elastic deformation, reducing the damage to the structure caused by the rigid collision between the fastening bolt 13 and the rotating pressure plate 7.

[0027] The working principle of this embodiment is as follows: During installation, firstly, the position of the slider 3 in the mounting hole 2 is adjusted to the required position by moving the two fixed pressure plates 4. Then, the rotating pressure plate 7 is pulled to keep the position of the slider 3 fixed, and the hook-and-loop seat body 12 is aligned with the threaded hole 5 on the slider 3. Then, the fastening bolt 13 is pre-tightened into the corresponding threaded hole 5 to facilitate the alignment of the hook-and-loop seat body 12 with the two sliders 3 and determine the required installation position. Then, the fastening bolt 13 is rotated to make it pass through the threaded hole 5. At this time, the fixed pressure plate 4 is pressed against the panel 1 through the anti-slip pad 11. Then, the rotating pressure plate 7 is rotated to make the protrusion 10 contact the upper surface of the reinforcing rib plate 14. At the same time, the elastic pad 9 on the rotating pressure plate 7 contacts the nut on the fastening bolt 13, thereby further restricting the position of the fastening bolt 13.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
