Description

Technical Field

[0001] This utility model relates to the field of door and window latches, specifically a spring-loaded door and window box latch. Background Technology

[0002] A bolt is a security component that prevents doors and windows from being opened from the outside. It also prevents doors and windows from being blown open by the wind or accidentally opened by children, thus preventing safety hazards. It can be said that bolts are an indispensable component in modern homes.

[0003] In the existing technology, door and window box latches are generally made of helical springs. Helical springs have many disadvantages. Their service life is not as good as that of spring clips, and they are prone to corrosion in high humidity environments, which leads to loss of elasticity. At the same time, their structure is also relatively complex and difficult to install. Therefore, a box latch that uses spring clips to replace helical springs is designed here. Utility Model Content

[0004] The purpose of this utility model is to provide a spring-loaded door and window box latch to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a spring-loaded door and window box latch, comprising a box-type latch body, a latch switch component, and a pin. The box-type latch body is a shell-shaped structure with an open back, and a rectangular opening is provided in the middle of its front side. The latch switch component is disposed in the rectangular opening and is movably connected to the box-type latch body through a rotating shaft. One end of the box-type latch body is provided with a through hole, through which the pin can pass. The cross-sectional shape of the pin is the same as the shape of the through hole. A spring is also provided inside the box-type latch body. The spring is fixedly connected to the pin through a pin connector and movably connected to one end of the latch switch component through a transmission structure.

[0006] As a further description of the above solution, screw holes are provided in the middle section of both ends of the box-type latch body.

[0007] As a further description of the above solution, the pin connector is an iron sheet, the part of which connects to the pin is bent upwards, and a strip-shaped opening is provided in its middle section. The width of the strip-shaped opening is greater than the diameter of the screw hole.

[0008] As a further description of the above solution, a fixing pin is provided at the other end of the box-type pin body opposite to the pin body, and the limiting position is set behind the spring piece to restrict the tail of the spring piece.

[0009] As a further description of the above scheme, the thickness of the tail end of the latch switch is less than that of the other end, and it is wider than the other end.

[0010] As a further description of the above solution, the front of the box-type latch body is provided with two grooves, which are symmetrically distributed at both ends of the rectangular opening in the middle section of the front of the box-type latch body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a spring sheet to replace the helical spring in the prior art, solving the problems of short lifespan of spring-type box pins, easy corrosion leading to decreased elasticity, complex structure, and difficult installation in the prior art. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 This embodiment provides a spring-loaded door and window box latch, including a box-type latch body 1, a latch switch component 4, and a pin 2. The box-type latch body 1 is a shell-shaped structure with an open back and a rectangular opening in the middle of its front. The latch switch component 4 is disposed in the rectangular opening and is movably connected to the box-type latch body 1 through a pivot 7. The latch switch component 4 is equivalent to a switch, which can control the pin 2 to pop out or retract. By manually flipping the latch switch component 4 to the other side, the switch can be turned on or off. One end of the box-type latch body 1 has a through hole through which the pin 2 can pass. The pin 2 is fixed to the door or window through this through hole. The cross-sectional shape of the pin 2 is the same as the shape of the through hole. Its shape is preferably circular, but square, triangular, or polygonal shapes do not affect the realization of its basic function.

[0020] Specifically, the main body 1 of the box-type latch is also provided with a spring piece 8. The spring piece 8 is fixedly connected to the pin body 2 through the pin body connector 9, and is movably connected to one end of the latch switch 4 through the transmission structure 10. When in use, the latch switch 4 is turned, and the latch switch 4 will cause the spring piece 8 to undergo elastic deformation through the transmission structure 10, thereby driving the pin body 2 at the other end to pop out or retract. The transmission structure 10 consists of two iron plates and a short shaft in the middle. The short shaft passes through one end of the latch switch 4, and the iron plates are symmetrically arranged on both sides of the short shaft and fixedly connected to the spring piece 8.

[0021] Specifically, the box-type pin body 1 has screw holes 5 in the middle of both ends, which can be used to fix the box-type pin body to the door or window with screws. The pin body connector 9 is an iron sheet, and the part connected to the pin body 2 is bent upward. The middle section has a strip-shaped opening, the width of which is greater than the diameter of the screw hole 5. The end of the spring piece 8 has a long strip-shaped opening, the width of which is greater than the diameter of the screw hole 5. The purpose of setting the openings on the spring piece 8 and the pin body connector 9 is to avoid interfering with the screw, so that it can pass directly through the spring piece 8 and the pin body connector 9. The purpose of setting it into a strip shape is to ensure that there is no mutual interference when the pin body 2 pops out or retracts.

[0022] Specifically, a fixing pin 6 is provided at the other end of the box-type pin body 1 opposite to the pin body 2. The fixing pin 6 is located behind the spring piece 8 and restricts the tail of the spring piece 8. This limiting structure allows the spring piece 8 to move within a certain range and keep it within a predetermined range.

[0023] Specifically, the thickness of the tail end of the latch switch 4 is less than that of the other end, and it is wider than the other end, which increases the contact area with the fingers and makes it easier to operate the latch switch 4. The front of the box-type latch body 1 is provided with two grooves 3, which are symmetrically distributed at both ends of the rectangular opening in the middle section of the front of the box-type latch body 1. The latch switch 4 can be completely placed in the grooves 3 and the rectangular opening, so that it does not protrude from the box-type latch body 1, thus achieving a more aesthetically pleasing effect.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
