Description

Technical Field

[0001] The utility model relates to the technical field of plug-in pin workpieces, in particular to a quick plug-in pin. Background Art

[0002] At present, in the production process, vehicle information is mainly written on blue cards, which are used to guide production. However, blue cards are easily worn or lost during the flow process, and they need to be scanned manually. In the paint shop, they need to be manually converted and the information is checked many times, resulting in a large loss of working hours and limited information entry positions. In the automotive OEM industry, the only way to write vehicle information that can meet the full process of the paint shop is the on-board electronic tag, which is mainly fixed to the vehicle through a fixture. The existing fixtures mainly have the following three structures:

[0003] The first type is the hook type, which uses a hook structure with a certain degree of elasticity to mount the electronic tag on the vehicle body. It has a simple structure and is easy to operate, but there is no structure fixed to the vehicle body. It is easy to shake and fall during the production process, causing quality risks to the vehicle body, and it cannot be used in the vehicle body flipping process during the welding production process.

[0004] The second type is threaded fastening, which uses a bolt structure corresponding to the threaded hole, and uses an electric tightening tool to fix the electronic tag on the car body. Although this structure has good installation stability, installation and removal require the use of special tools, and require the cooperation of both hands, which takes a long time. In addition, if the tag installation holes of different models are inconsistent (the inner diameter of the threaded hole is blocked, or even a non-threaded hole), this type of tooling cannot be used universally, and multiple tooling fixtures need to be configured, resulting in a waste of investment;

[0005] The third type is the R / B quick-pull pin type, which uses a positioning quick-pull pin structure to fix the label base plate on the vehicle body. This type of tooling consists of a positioning pin and a pin, and requires employees to cooperate with both hands to operate. In addition, if the positioning pin considers the versatility of the installation hole, there will be multiple pin holes on the pin. Employees need to pay attention to the correct position of the pin during installation, resulting in a longer installation time. In addition, this structure requires a large space on both the inside and outside of the installation hole, which has greater restrictions on the selection of installation holes.

[0006] In summary, the main defects of the existing vehicle tag fixture technology are: poor fixture versatility; high difficulty in assembly and installation, long installation time (≥1min); and high requirements for installation hole positions. Utility Model Content

[0007] The purpose of the utility model is to provide a quick-pull pin as a fixture for a vehicle tag, so as to solve the defects of the prior art fixture for a vehicle tag, such as poor universality, high difficulty in assembly and installation, long installation time (≥1min), and high requirements for the installation hole position. The preferred technical solution among the many technical solutions provided by the utility model can produce many technical effects as described below.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] The utility model provides a quick-pull plug, comprising a mounting frame, a clamping member, and an elastic member. One end of the mounting frame comprises a protruding rod, and the protruding rod is used to extend into a through hole on a device. The middle part of the clamping member is hinged on the mounting frame, an elastic member is arranged between the first end of the clamping member and the mounting frame, and a first hook is arranged at the second end of the clamping member. When the clamping member rotates in a resetting direction under the elastic force of the elastic member, the first hook rotates in a direction away from the protruding rod, so that the first hook inserted into the through hole and the protruding rod are clamped on the device.

[0010] Preferably, a second hook is further provided on the clamping member, the height of the second hook is smaller than the height of the first hook, and when the second hook abuts against the side of the through hole, the first hook can still clamp the end of the through hole.

[0011] Preferably, a recessed portion is provided on one side of the clamping member where the second hook is provided, so that the top of the second hook is within the range of a line between the top of the first hook and the position of the recessed portion.

[0012] Preferably, a first groove is provided on the extending rod, and the first groove extends from one end of the extending rod to the other end, so that the clamping member can extend out or retract into the first groove.

[0013] Preferably, a first mounting plate is provided on the mounting frame, the extending rod is mounted on the first mounting plate, and the first mounting plate is provided with a second groove for the clamp to pass through.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0029] This specific implementation provides a quick-release plug, which solves the defects of the quick-release plug in the prior art, such as poor universality of the fixture, high difficulty in assembly and installation, long installation time (≥1 min), and high requirements for the installation hole position.

[0030] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0031] Reference Figure 1-Figure 5The utility model provides a quick-pull pin, including a mounting frame 1, a clamping member 2, and an elastic member 3. The mounting frame 1 can be used to install an electronic tag 11. One end of the mounting frame 1 includes a protruding rod 4, and the length of the protruding rod 4 is 14-17 mm. The protruding rod 4 is used to extend into a through hole on the device; the clamping member 2 is hinged on the mounting frame 1, so that the clamping member 2 forms a lever, and the second end of the clamping member 2 is provided with a first hook portion 21, and an elastic member 3 is provided between the first end of the clamping member 2 and the mounting frame 1. When the clamping member 2 rotates in a reset direction under the action of the elastic member 3, the first hook portion 21 rotates in a direction away from the protruding rod 4, so that the first hook portion 21 inserted into the through hole and the protruding rod 4 are stuck on the device. That is, the elastic member 3 includes two states. When the elastic member 3 is in the first state, that is, the elastic member 3 is in the original state or the slightly stressed state, there is a certain distance between the second end of the clamp 2 and the extension rod 4, that is, the second end of the clamp 2 is away from the extension rod 4. At the same time, when the clamp 2 and the extension rod 4 are arranged in the through hole, the first hook 21 of the clamp 2 can hook the end of the through hole, and the extension rod 4 is stuck on the side wall of the through hole, so that the quick-pull pin can be fixed in the through hole; when the first end of the clamp 2 is close to the mounting frame 1, that is, the elastic member 3 is in the second state, the elastic member 3 is stressed and accumulates elastic force. In principle, when the first end of the card 2 approaches the mounting frame 1, the second end of the card 2 also approaches the extension rod 4 to reduce the space occupied by the extension rod 4 and the card 2, making it convenient for the card 2 and the extension rod 4 to extend into or retract out of the through hole on the device. When the card 2 enters the through hole on the device, the card 2 is released, and under the action of elastic force, the card 2 rotates to make the first end of the card 2 move away from the mounting frame 1, and the second end of the card 2 also moves away from the extension rod 4, and the first hook 21 on the card 2 hooks the end of the through hole on the device, thereby preventing the quick-pull pin from being separated from the device, wherein the device can be an automobile or a processed part.

[0032] With such a configuration, you only need to press the card to make the second end of the card approach and move away from the extension rod, and at the same time the first hook on the card hooks the end of the through hole, so that the quick pull pin is fixed to the equipment, saving fixing time and facilitating disassembly. It has great versatility and can be applied to a certain range of through holes.

[0033] In this embodiment, for devices with relatively thin thickness, after the first hook 21 is stuck in the end of the through hole, the quick-pull pin is prone to shaking. In order to reduce the shaking, a second hook 22 is further provided on the clamp 2, and the second hook 22 is arranged between the hinge position between the clamp 2 and the mounting frame 1 and the first hook 21, thereby shortening the distance at which the extension rod 4 is set in the through hole. For relatively deep through holes, in order to reduce the influence of the second hook 22 on the first hook 21, the height of the second hook 22 is smaller than the height of the first hook 21, and it is ensured that when the second hook 22 is against the side of the through hole, the first hook 21 can still clamp the end of the through hole.

[0034] In this embodiment, in order to further reduce the influence of the second hook 22 on the first hook 21, the clamp 2 is provided with a recessed portion 23 on one side of the second hook 22, so that the top of the second hook 22 is within the range of the line between the top of the first hook 21 and the position of the recessed portion 23, and preferably, when the first hook 21 hooks the end face of the through hole on the device, the second hook 22 is hidden in the first groove 41, thereby greatly reducing the influence of the second hook 22 on the first hook 21.

[0035] In this embodiment, in order to facilitate the extension rod 4 to extend into the through hole on the device, a first groove 41 is provided on the extension rod 4, and the first groove 41 extends from one end of the extension rod 4 to the other end, so that the card 2 can extend or retract into the first groove 41. When people need to insert the quick-pull pin into the through hole on the device, people press the card 2 to make the extension rod 4 close to the second end of the card 2. Specifically, the card 2 needs to be retracted into the inside of the first groove 41, which greatly reduces the space between the card 2 and the extension rod 4, thereby facilitating the extension rod 4 to be inserted into or out of the through hole on the device.

[0036] In this embodiment, in order to facilitate the installation of the extension rod 4, a first mounting plate 5 is provided on the mounting frame 1, and the extension rod 4 is installed on the first mounting plate 5. The first mounting plate 5 is provided with a second groove 51 for the card member 2 to pass through, that is, during installation, the first mounting plate 5 can also provide a reference positioning, so that the two ends of the through hole are restricted between the first mounting plate 5 and the first hook 21, and the shaking of the quick-pull pin can be avoided.

[0037] In this embodiment, in order to prevent the clamping member 2 from being separated from the first mounting plate 5 , a stopper 8 is provided at the opening of the second groove 51 , and the stopper 8 seals the opening of the second groove 51 .

[0038] In this embodiment, in order to facilitate people to paste the label or install the electronic label 11, a second mounting plate 9 is provided on the mounting frame 1, and the second mounting plate 9 is used to fix the electronic label 11, wherein the electronic label 11 can be fixed to the second mounting plate 9 by bolts, so that it is convenient to disassemble after use, so when people need to install the electronic label 11, they only need to install it on the second mounting plate 9.

[0039] In this embodiment, in order to facilitate people to hold it, a handle 6 is provided at one end of the mounting frame 1 away from the extension rod 4 , and the handle 6 is close to or far away from the first end of the clamp 2 .

[0040] In this embodiment, a pressing plate 7 is provided at the first end of the clamping member 2 , and the elastic member 3 is installed between the mounting frame 1 and the pressing plate 7 .

[0041] In this embodiment, in order to prevent the electronic tag from being broken and damaged due to uneven force when the plug pin falls, a baffle 10 is provided at the lower end of the second mounting plate 9. The baffle 10 is provided on one side of the electronic tag 11 to support the electronic tag 11. That is, when used improperly, the electronic tag may fall, which may damage the electronic tag. Providing a baffle on the back of the electronic tag 11 can reduce the damage to the electronic tag and extend the service life of the electronic tag 11.
