[0002] Latches are widely used in doors, windows, storage boxes, cabinets and other equipment. Their function is to prevent the door from being opened, and they have anti-theft or fixing functions. Traditional latches generally include a fixed base and a movable pin. The movable pin is generally L-shaped and is telescopically mounted on the fixed base. The fixed base mostly adopts a sheet structure with a relatively simple design and a relatively thin structure. It is easy to deform and damage after long-term use, and the movable pin is also prone to loosening, slipping or even falling off, posing a major safety hazard. Utility Model Content

[0003] In order to solve the above problems, the present application provides a stainless steel latch.

[0004] The present application provides a stainless steel latch that adopts the following technical solution:

[0005] A stainless steel latch comprises a first fixed seat, a second fixed seat and a movable pin, wherein a slot is provided inside the first fixed seat and the second fixed seat, and the movable pin is telescopically installed in the slot, the first fixed seat, the second fixed seat and the movable pin are all made of stainless steel, and the cross-sections of the movable pin and the slot are both square, the tail of the movable pin is upwardly protruding and provided with a tail plate, the inner side of the tail plate and the upper part of the tail of the movable pin are provided with a groove, a limit fastener is movably provided inside the groove, and a limit buckle groove matching the limit fastener is provided on the top of the first fixed seat.

[0006] Furthermore, the position-limiting fastener includes a buckle portion and a pressing plate. The pressing plate is vertically disposed within the groove, with its center lateral sides rotatably connected to the side walls of the groove via a rotating shaft. The buckle portion is horizontally fixedly connected to the center of the front side of the pressing plate. A return spring is also fixedly connected between the bottom of the pressing plate and the groove.

[0007] Through the above technical solution, by pressing the pressing plate, the front end of the buckle part can be tilted up. When the movable pin is in the inserted state, the pressing plate is released, and the front end of the buckle part can be embedded in the limiting buckle groove to achieve locking and prevent the movable pin from sliding.

[0008] Furthermore, a strip groove is provided on one side surface of the first fixing seat, a sliding rod slides through the strip groove, and an inner end of the sliding rod is detachably fixedly connected to a movable pin.

[0009] The above technical solution can prevent the movable pin from falling out from the rear end of the first fixing seat, and the detachable design facilitates assembly.

[0010] Furthermore, the length of the strip groove is the same as the maximum length that the front end of the movable pin can extend from the first fixing seat. The first fixing seat is fixedly connected to magnet blocks at both ends located outside the strip groove, and the outer end of the slide rod is fixedly connected to a positioning block that can be attracted by the magnet.

[0011] Through the above technical solution, when the movable pin is in the engaged state or the retracted state, the positioning block can be adsorbed by the magnet blocks at both ends, which can improve the structural stability. When the movable pin is in the retracted state, the positioning block is adsorbed by the magnet block at the rear end, so that it will not slide freely in the first fixed seat, which can effectively prevent the movable pin from protruding from the first fixed seat in the unengaged state, and prevent the front end of the movable pin from hitting the second fixed seat in unexpected situations such as wind blowing, causing deformation or structural loosening.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] (1) The application provides a limit buckle at the tail of the movable pin. When in use, the pressing plate is pressed, and the front end of the buckle portion can be tilted up. When the movable pin is in the inserted state, the pressing plate is released, and the front end of the buckle portion can be embedded in the limit buckle groove to achieve locking, prevent the movable pin from sliding, and improve the structural stability;

[0014] (2) The present application sets a magnet block on the side of the first fixed seat and a positioning block on the side of the movable pin. When the movable pin is in the inserted state or the retracted state, the positioning block can be adsorbed with the magnet blocks at both ends, thereby further improving the structural stability and enhancing practicality.

[0023] Example 1:

[0024] The present application is further described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the present application discloses a stainless steel latch, comprising a first fixed seat 1, a second fixed seat 2 and a movable pin 3. A slot is provided inside the first fixed seat 1 and the second fixed seat 2, and the movable pin 3 is telescopically installed in the slot. The first fixed seat 1, the second fixed seat 2 and the movable pin 3 are all made of stainless steel. The cross-sections of the movable pin 3 and the slot are square. The tail of the movable pin 3 is upwardly protruding and provided with a tail plate 4. A groove 5 is provided on the inner side of the tail plate 4 and above the tail of the movable pin 3. A limit fastener 6 is movably provided inside the groove 5. A limit buckle groove 7 matching the limit fastener 6 is provided on the top of the first fixed seat 1.

[0026] See Figure 2 and Figure 3The position-limiting fastener 6 includes a snap portion 61 and a pressing plate 62. The pressing plate 62 is vertically disposed within the groove 5, with its center pivotally connected to the sidewalls of the groove 5 via a rotating shaft. The snap portion 61 is horizontally fixedly connected to the center of the front side of the pressing plate 62. A return spring 8 is also fixedly connected between the bottom of the pressing plate 62 and the groove 5. By pressing the pressing plate 62, the front end of the snap portion 61 can be tilted up. When the pressing plate 62 is released when the movable pin 3 is in the engaged state, the front end of the snap portion 61 can be inserted into the position-limiting buckle groove 7, locking the movable pin 3 and preventing it from sliding.

[0027] See Figure 1 and Figure 2 A strip groove 9 is formed on one side of the first fixing base 1. A slide bar 10 slides through the strip groove 9. The inner end of the slide bar 10 is detachably fixed to the movable pin 3, preventing the movable pin 3 from dislodging from the rear end of the first fixing base 1. The detachable design facilitates assembly. The length of the strip groove 9 is the same as the maximum length that the front end of the movable pin 3 can extend from the first fixing base 1. The first fixing base 1 is fixedly connected to magnet blocks 11 at both ends outside the strip groove 9. The outer end of the slide bar 10 is fixedly connected to a positioning block 12. The positioning block 12 is made of a material that can be attracted by magnets. When the movable pin 3 is in the inserted state or retracted state, the positioning block 12 can be attracted to the magnet blocks 11 at both ends, which can improve the structural stability. When the movable pin 3 is in the retracted state, the positioning block 12 is attracted by the rear end magnet block 11, preventing it from sliding freely in the first fixing base 1. This effectively prevents the movable pin 3 from protruding from the first fixing base 1 when not inserted. It also prevents the front end of the movable pin 3 from hitting the second fixing base 2 in unexpected situations such as wind, causing deformation or structural loosening.

[0028] The embodiment of the present invention is a stainless steel latch according to the following principles: the present invention provides a stopper 6 at the tail of the movable pin 3. When in use, the pressing plate 62 is pressed, and the front end of the latch portion 61 can be tilted. When the movable pin 3 is in the inserted state, the pressing plate 62 is released, and the front end of the latch portion 61 can be inserted into the stopper groove 7, thereby locking the movable pin 3 and preventing it from sliding. The present invention also provides a magnet block 11 on the side of the first fixing seat 1 and a positioning block 12 on the side of the movable pin 3. When the movable pin 3 is in the inserted state or the retracted state, the positioning block 12 can be attracted by the magnet block 11 at both ends, thereby improving the structural stability. When the movable pin 3 is in the retracted state, the positioning block 12 is attracted by the rear magnet block 11, preventing it from sliding freely in the first fixing seat 1. This effectively prevents the movable pin 3 from protruding from the first fixing seat 1 when not inserted, and prevents the front end of the movable pin 3 from hitting the second fixing seat 2 in unexpected situations such as wind, causing deformation or structural loosening, thereby further improving practicality.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
