Description

Technical Field

[0001] This utility model relates to a latch, and more particularly to a special quick-locking latch. Background Technology

[0002] A latch is a component that can be used on doors, windows, boxes, etc., to close these components.

[0003] There are generally two types of existing pins: one is a regular pin, in which the pin rod does not have a spring-loaded function; the other is a spring pin, in which a spring is installed, and the spring is connected to the pin rod, which has a spring-loaded function. This type of spring pin can be used in special equipment.

[0004] Because spring-loaded pins have a rebound function, they are typically used in scenarios where this function is required. However, since spring-loaded pins generally do not have protective components such as covers or housings, the following problems may occur during their use: 1. Dust or even debris can easily accumulate on the pin and spring, making the pin unable to be pulled; 2. Due to the spring's rebound force, the pin can easily injure the user when using spring-loaded pins. Utility Model Content

[0005] The purpose of this invention is to provide a special quick-locking pin to solve the problems existing in the prior art.

[0006] According to one aspect of the present invention, a special quick-locking pin is provided, including a base, a cover plate, a spring and a pin rod. One end of the pin rod passes laterally through the base. The spring is disposed on the base. When the pin rod is pulled, the spring is compressed and exerts a pushing force on the pin rod. The cover plate is closed on the base so that the cover plate can cover the spring and the pin rod partially located in the base.

[0007] In some embodiments, the base includes a base plate and two side plates, which are vertically disposed on both sides of the base plate. One end of the pin passes laterally through the two side plates. The portion of the pin located in the base is provided with a blocking part that can abut against one of the side plates of the base. One end of the spring abuts against the blocking part, and the other end abuts against the other side plate.

[0008] In some embodiments, a limiting part is provided on the bottom plate of the base. The limiting part is located in the middle of the bottom plate. When the blocking part moves to the middle position of the base, it will be blocked by the limiting part.

[0009] In some embodiments, the limiting part is a limiting post, and there are two limiting posts, which are located on both sides of the pin rod, and the blocking part is cylindrical.

[0010] In some embodiments, the limiting part is a protrusion, there are two protrusions, the two protrusions are located on both sides of the pin rod, and the protrusions are provided with corresponding notches.

[0011] In some implementations, screw holes are provided on the base plate.

[0012] In some implementations, one end of the pin is bent.

[0013] This invention includes a cover plate that covers the middle portion of the spring and the pin, preventing dust from entering them. Furthermore, the cover plate prevents the user's hands from touching the spring and pin, improving user safety. Since this invention is a spring-loaded pin, it can be used in specialized equipment for quick insertion and locking. The base plate of this invention has a limiting part that restricts the movement of the pin, preventing excessive pulling that could damage the spring and shorten the lifespan of the invention.

[0020] 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.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Figure 1 and Figure 2 The diagram schematically illustrates the structure of a special quick-locking pin according to one embodiment of the present invention.

[0023] like Figure 1 and Figure 2 As shown, a special fast-locking pin includes a base 1, a cover plate 2, a spring 3, and a pin rod 4.

[0024] Figure 1 and Figure 2 In this embodiment, the upper end of the pin 4 can pass laterally through the base 1. The spring 3 can be installed on the base 1 and is sleeved on the pin 4. When the pin 4 is pulled, the spring 3 is compressed. When the pin 4 is released, the spring 3 pushes the pin 4 back to its original position under the restoring force. The special quick-lock pin in this embodiment is provided with a cover plate 2, which covers the base 1 so that the cover plate 2 can cover the spring 3 and part of the pin 4 located in the base 1. Therefore, by providing the cover plate 2, dust can be blocked, preventing dust from entering the spring 3 and the pin 4 in the base 1. In addition, it can also protect the user's hands, preventing the user's hands from directly contacting the spring 3 and the pin 4.

[0025] The structure of base 1 is described in detail below. The structure of base 1 is as follows: Figure 1 and Figure 2 As shown, the base 1 includes a base plate 11 and two side plates 12. The two side plates 12 are integrally formed on both sides of the base plate 11 and are vertically arranged. The upper end of the pin 4 can pass through the two side plates 12 laterally. The portion of the pin 4 located in the base 1 has a blocking part 41, which abuts against the upper side plate 12 of the base 1. The upper end of the spring 3 abuts against the blocking part 41, and the lower end of the spring 3 abuts against the other side plate 12. The spring 3 is always in a compressed state. Therefore, the upper end of the spring 3 always exerts a pushing force on the blocking part 41 of the pin 4. Without the action of external force, the blocking part 41 of the pin 4 is always abutted against. Figure 2 As shown in the upper side plate 12, when the pin 4 is pulled down, the pin 4 will move downward, and the spring 3 will be compressed to a greater degree. When the pin 4 is released, the pin 4 will be pushed upward to reset under the restoring force of the spring 3.

[0026] Therefore, by setting the spring 3, the pin 4 can be reset by itself, which allows the pin 4 to be quickly inserted into the socket and achieves the effect of quick locking.

[0027] like Figure 2 As shown, in this embodiment, a limiting part 13 is provided on the base plate 11 of the base 1, and the limiting part 13 is located in the middle of the base plate 11. When the pin 4 is pulled down and moves a certain distance, the pin 4 will reach the limiting part 13 and be blocked by the limiting part 13. At this time, the limiting part 13 will restrict the pin 4 from continuing to move. Therefore, by setting the limiting part 13, the movement stroke of the pin 4 can be limited, preventing the movement stroke of the pin 4 from being too large and affecting the overall service life.

[0028] In this embodiment, the limiting part 13 is a limiting post, and there are two limiting posts, which are located on both sides of the pin rod 4. The blocking part 41 is cylindrical and is erected in the middle of the base 1. In other embodiments, the shape of the limiting part 13 can be set according to actual needs. For example, the limiting part 13 can be square. No matter how the shape of the limiting part 13 is changed, as long as the limiting part 13 can limit the movement stroke of the pin rod 4, it is acceptable.

[0029] Figures 3-5 The diagram illustrates the structure of a special quick-locking pin according to another embodiment of the present invention.

[0030] like Figures 3-5 As shown, the limiting part 13 is a protrusion, and there are two protrusions, which are located on both sides of the pin 4, and the protrusions are provided with corresponding notches. The protrusions can play the same role as in the above embodiment, that is, when the pin 4 is pulled a certain distance, the pin 4 will be blocked by the protrusion. At this time, the protrusion will restrict the pin 4 from continuing to move. Therefore, the movement stroke of the pin 4 can be limited by the protrusion.

[0031] In addition to the limiting part 13 and the aforementioned notch, Figures 3-5 The other parts of the structure of the special fast-locking pin in the illustrated embodiment are similar to... Figure 1 and Figure 2 The special fast-locking pins in the illustrated embodiments have the same structure, therefore they will not be described in detail.

[0032] like Figures 1-5 As shown, screw holes 111 can be integrally formed on the base plate 11. Screws can pass through the screw holes 111. Therefore, the base plate 11 can be fixed to the door of the special equipment or other positions by means of screws and screw holes 111.

[0033] like Figures 1-5As shown, one end of the pin 4 is bent. Therefore, the bent pin 4 will not completely enter the space formed by the base 1.

[0034] This invention includes a cover plate 2, which covers part of the spring 3 and the pin 4, preventing dust from entering them. Furthermore, the cover plate prevents the user's hands from touching these components, improving user safety. Since this invention uses a spring-loaded pin, it can be used in specialized equipment for quick insertion and locking. The base plate 11 of the base 1 has a limiting part 13, which restricts the movement of the pin 4, preventing excessive pulling that could damage the spring 3 and shorten the lifespan of the invention.

[0035] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
