Technical Field
[0001] The utility model relates to the field of latches, in particular to a latch which is convenient for installation and adjustment. Background Art
[0002] A latch is an anti-theft component that prevents doors and windows from being opened from the outside. Modern latch devices such as doors and windows are generally made of metal and are generally divided into two parts, one part with a movable rod, and the other part is a latch hole. When installing the latch, the position of the movable rod needs to correspond to the position of the latch hole, otherwise the movable rod is difficult to insert into the interior of the latch hole. In addition, since the latch is installed with screws, if there is a deviation in the position of the two, it is necessary to disassemble and reinstall and adjust. On the one hand, it causes high damage to the doors and windows and affects the aesthetics. On the other hand, the operation is also more troublesome. Utility Model Content
[0003] The main purpose of the utility model is to provide a latch that is easy to install and adjust, which can effectively solve the problems in the background technology.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a pin that is easy to install and adjust, including a first mounting plate and a second mounting plate with mounting holes on the surface, a pin rod is movably inserted inside the first mounting plate, a penetrating mounting groove is provided in the middle of the second mounting plate, a movable plate is movably installed inside the mounting groove, a pin seat is installed on the front side of the movable plate, the middle part of the pin seat is penetrated and the inner wall diameter is adapted to the pin rod diameter.
[0005] Slide blocks are fixedly mounted on the top and bottom of the movable plate, guide grooves are formed on the top and bottom of the inner wall of the mounting groove, and the slide blocks are movably mounted inside the guide grooves.
[0006] A guide rod is fixedly installed inside the guide groove, and the guide rod movably penetrates the surface of the slider. A spring is sleeved on the surface of the guide rod, one end of the spring is fixed on the surface of the slider, and the other end of the spring is fixed inside the guide groove.
[0007] The top of the pin seat is provided with an inclined arc surface, and the position of the inclined arc surface close to the center of the pin seat is lower than the position far from the center.
[0008] A conical extrusion head is fixedly mounted on the bottom of the pin rod, the end of the extrusion head is rounded, and the extrusion head and the pin rod are an integrally formed structure.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] 1. In the utility model, by setting the guide groove, the slider, the mounting groove and the movable plate, when the mounting positions of the first mounting plate and the second mounting plate deviate, it is only necessary to change the position of the movable plate. At this time, the slider moves inside the guide groove, so that the movement of the movable plate will not be offset until the pin rod can be inserted into the pin seat. Compared with the traditional bolt installation, there is no need to change the mounting position, and the misalignment adjustment is very convenient.
[0011] 2. In the utility model, by providing a pin rod, a pin seat and an inclined arc surface, when the pin rod moves downward, its bottom will first abut against the top of the inclined arc surface. In the process of applying downward force, as the pressure increases, the pin seat will gradually move laterally until the pin rod is inserted into the middle position of the pin seat. In this process, there is no need to operate the movement of the pin seat while inserting the pin rod, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-4As shown, a latch that is easy to install and adjust includes a first mounting plate 1 and a second mounting plate 2 with mounting holes on the surface. The first mounting plate 1 has four mounting holes on the surface, and the second mounting plate 2 has two mounting holes on the surface. A pin rod 3 is movably inserted inside the first mounting plate 1, and the pin rod 3 can move longitudinally on the surface of the first mounting plate 1. A penetrating mounting groove 4 is provided in the middle of the second mounting plate 2, and the mounting groove 4 penetrates front and back. A movable plate 5 is movably installed inside the mounting groove 4, and the movable plate 5 moves laterally. A pin seat 6 is installed on the front side of the movable plate 5, and the middle part of the pin seat 6 penetrates and the inner wall diameter is adapted to the diameter of the pin rod 3.
[0019] When the installation of the first mounting plate 1 and the second mounting plate 2 produces a position deviation, it is difficult for the pin rod 3 to be inserted into the interior of the pin seat 6. At this time, it is only necessary to change the position of the movable plate 5 to insert the pin rod 3 into the interior of the pin seat 6. Compared with the traditional pin installation, there is no need to change the installation position, and the misalignment adjustment is very convenient.
[0020] Slide blocks 7 are fixedly installed on the top and bottom of the movable plate 5 , and the slide blocks 7 and the movable plate 5 are an integrally formed structure. Guide grooves 8 are opened on the top and bottom of the inner wall of the installation groove 4 , and the slide blocks 7 are movably installed inside the guide grooves 8 .
[0021] A guide rod 9 is fixedly installed inside the guide groove 8. The guide rod 9 movably penetrates the surface of the slider 7. A spring 10 is sleeved on the surface of the guide rod 9. There are two springs 10, which are symmetrically arranged on both sides of the slider 7. One end of the spring 10 is fixed to the surface of the slider 7, and the other end of the spring 10 is fixed inside the guide groove 8. When the spring 10 is in a normal state, it can relatively fix the pin seat 6 to ensure that the position of the pin seat 6 is stable. When there is no misalignment during installation, it can be stably inserted into the inside of the pin seat 6.
[0022] The top of the pin seat 6 is provided with an inclined arc surface 11, and the position of the inclined arc surface 11 close to the center of the pin seat 6 is lower than the position far from the center.
[0023] When the pin rod 3 moves downward, its bottom will first contact the top of the inclined arc surface 11. However, due to its inclined surface, in the process of applying downward force, as the pressure increases, the pin seat 6 will gradually move laterally until the pin rod 3 is inserted into the middle position of the pin seat 6. In this process, there is no need to operate the movement of the pin seat 6 while inserting the pin rod 3, which is more convenient to use.
[0024] A conical extrusion head 12 is fixedly mounted at the bottom of the pin rod 3, and can stably move downward and fall on the inclined arc surface 11. The end of the extrusion head 12 is rounded, and the extrusion head 12 and the pin rod 3 are an integrally formed structure to ensure the stability of the connection between the two.
[0025] It should be noted that the utility model is a latch that is easy to install and adjust. During use, when the installation of the first mounting plate 1 and the second mounting plate 2 produces a position deviation, it is difficult for the pin rod 3 to be inserted into the interior of the pin seat 6. At this time, the downward pressure is gradually increased. As the pressure increases, the pin seat 6 will gradually move laterally until the pin rod 3 is inserted into the middle position of the pin seat 6. In this process, there is no need to operate the movement of the pin seat 6 while inserting the pin rod 3. The pin rod 3 can be easily inserted into the interior of the pin seat 6.
[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
