Abstract
Description
[Technical field]
[0001] The utility model relates to a latch structure. [Background technology]
[0002] Latches are usually used to connect two or more connectors, and these connectors are provided with pin holes for the latch to pass through. In order to prevent the latch from loosening without reason, the latches on the market at this stage are equipped with one or more retractable steel balls to prevent the latch from loosening easily. However, in actual application, it is found that after the latch is repeatedly plugged in and out, the surface of the steel ball is easily scratched and worn, resulting in greater friction between the steel ball and the hole of the latch. Occasionally, the steel ball gets stuck in the hole and fails to pop out in time, causing the anti-loosening function of the latch to fail.
[0003] Therefore, it is necessary to make further improvements. [Contents of the utility model]
[0004] The purpose of the utility model is to overcome the above problems. We provide a latch structure that can be replaced when the steel ball is damaged.
[0005] To achieve the above-mentioned purpose, the utility model provides a latch structure, which includes a pin body, a front end of the pin body is provided with an arc-shaped head, a rear end of the pin body is provided with a pull ring, the pin body is provided with a through-type installation channel at a position close to the head, the installation channel is perpendicular to the axial direction of the pin body, and a steel ball, a spring member and a mounting seat are sequentially arranged in the installation channel, at least a part of the steel ball protrudes from the surface of the pin body from the installation channel, two ends of the spring member are abutted against the steel ball and the mounting seat, and the mounting seat is threadedly connected and fixed to the installation channel.
[0006] In one or more embodiments, an internal thread structure is provided at another end portion of the installation channel relative to the steel ball, and an external thread structure matching with the internal thread structure is provided on the outer side of the installation seat.
[0007] In one or more embodiments, the other end of the mounting seat relative to the spring member is provided with a straight slot, a cross slot, a triangular slot, or a pentagonal slot.
[0008] In one or more embodiments, the difference between the outer diameter of the spring element and the diameter of the mounting channel is less than 0.3 MM.
[0009] In one or more embodiments, the surface of the mounting seat does not protrude beyond the surface of the pin body.
[0010] In one or more embodiments, the rear end of the pin body has a ring seat, a mounting hole is opened on the ring seat, and the pull ring is passed through the mounting hole.
[0011] In one or more embodiments, the pin body, the steel ball, the spring element and the mounting seat are all made of stainless steel.
[0012] Compared with the background technology, the utility model has the following effects: the bolt improves the installation structure of the steel ball. For the user, the bolt can be disassembled and the steel ball can be replaced according to the degree of wear of the steel ball at a later time, ensuring that the surface of the steel ball is smooth and can be extended and retracted freely; in addition, it can also be determined whether the spring needs to be replaced according to the elastic force of the spring, which is beneficial to reducing the use cost.
Brief Description of the Drawings
[0013] Figure 1 It is a structural schematic diagram of the latch of the utility model. [Specific implementation method]
[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0015] Please see Figure 1 The present application provides a latch structure, which includes a pin body 1, a front end of the pin body is provided with an arc-shaped head 2, the arc-shaped head is easy for the pin body to be inserted into the pin hole, and a pull ring 3 is provided at the rear end of the pin body. The pull ring can be convenient for the user to pull out the pin body, and the pin body 1 is provided with a through-type installation channel 4 at a position close to the head, and the installation channel is perpendicular to the axial direction of the pin body. A steel ball 5, a spring member 6 and a mounting seat 7 are sequentially arranged in the installation channel, and at least a part of the steel ball protrudes from the surface of the pin body from the installation channel, and the protruding steel ball is used to prevent After the pin body is inserted into the connecting piece, it is easy to loosen from the connecting piece, which plays a role in preventing loosening. The two ends of the spring member 6 are against the steel ball 5 and the mounting seat 7, and the mounting seat is fixed with a thread connection to the mounting channel. When the steel ball is worn on the surface due to use, resulting in the steel ball being unable to retract and contract freely, the user can remove the mounting seat, take out the steel ball and the spring member, replace the new steel ball, and then reinstall the spring member and the mounting seat for use; in addition, when the spring member has insufficient elasticity, the spring member can be replaced by removing the mounting seat to save the use cost.
[0016] The installation channel 4 is provided with an internal thread structure at the other end portion relative to the steel ball 5, and the outer side surface of the mounting seat 7 is provided with an external thread structure matching the internal thread structure. The thread structure is used for installation, which has the advantages of easy installation and disassembly.
[0017] The other end of the mounting seat 7 relative to the spring member 6 is provided with a straight slot 8 or a cross slot or a triangular slot or a pentagonal slot, which can be selected according to actual needs. Generally, in order to facilitate finding tools to disassemble the mounting seat, the slot of the mounting seat is selected to be a straight slot or a cross slot.
[0018] The difference between the outer diameter of the spring component and the diameter of the installation channel is less than 0.3MM, which has a limiting effect on the spring component to prevent the spring component from twisting and deforming when it is expanded or compressed, so that the spring component can better support the steel ball.
[0019] The surface of the mounting seat 7 does not protrude from the surface of the pin body 1. Preferably, the surface of the mounting seat is recessed into the pin body, so as to avoid the mounting seat affecting the insertion and removal of the pin body.
[0020] The rear end of the pin body 1 is provided with a ring seat 9, a mounting hole is opened on the ring seat, the pull ring is passed through the mounting hole, and the ring seat and the pin body are an integral structure.
[0021] The pin body 1, the steel ball 5, the spring member 6 and the mounting seat 7 are all made of stainless steel. The stainless steel is rust-proof and can prevent the steel ball or the pin body from rusting and causing the steel ball to be unable to extend and retract freely.
[0022] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
