Description

Technical Field

[0001] The utility model relates to a quick-detachable marble pin shaft. Background Art

[0002] The quick-release pin is a pin with a retractable pin. The pin is stuck by the pin to prevent it from loosening from the shaft hole. The quick-release pins on the market at this stage will be scratched and uneven on the surface of the pin during repeated extraction, which will cause the pin to be stretched and retracted unsmoothly. Sometimes it will even get stuck in the hole and cannot be pulled out. In this case, the pin can basically be scrapped because its safety cannot be guaranteed. However, scrapping a pin for this reason will waste a lot of resources. The price of the pin is not high, but the quick-release pins on the market at this stage cannot be disassembled and replaced by users.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a quick-release marble pin shaft, which is designed as a detachable structure and allows users to replace marbles.

[0005] The utility model proposes a quick-release marble pin, which comprises a pin body, a pin cover and a plurality of marbles. The circular diameter of the pin cover is equal to the circular diameter of the pin body. The pin cover is detachably connected to the lower end of the pin body and forms an installation cavity therewith. The side wall of the pin body is provided with a marble groove connected to the installation cavity. The marble is arranged in the marble groove and at least a part of it can protrude from the marble groove. A spring part and a marble reset part that resists the marble are provided in the installation cavity. The spring part is used to keep the marble reset part resisting the marble. The marble reset part is provided with an operating rod extending out of the installation cavity.

[0006] In one or more embodiments, the marble reset member is a reset disk, the outer edge of the reset disk is arc-shaped, and the outer edge of the reset disk is used to support the marble so that the marble protrudes out of the marble groove.

[0007] In one or more embodiments, the operating rod is disposed at the top end and in the middle of the reset disc, and the pin shaft body is provided with a channel for the operating rod to extend out.

[0008] In one or more embodiments, the number of marbles is three or more, and three marble grooves are circumferentially distributed on the side wall of the pin shaft body, and a marble is placed in each marble groove.

[0009] In one or more embodiments, the marble reset member and the pin cover are both provided with a boss, and the boss is provided for the spring member to be sleeved.

[0010] In one or more embodiments, the pin cover is provided with a guide shaft for inserting a marble reset member, and the marble reset member is provided with a hole for matching with the guide shaft.

[0011] In one or more embodiments, an internal thread structure is provided on the inner side of the pin shaft body, and the pin shaft cover is provided with an external thread structure matching with the internal thread structure.

[0012] The utility model has the beneficial effects that the quick-detachable marble pin is assembled from a pin body and a pin cover; the pin cover can be opened to remove the marbles inside and replace them with new marbles; after the marbles are replaced, the marble pin can be used normally again, thus reducing waste of resources.

[0015] 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.

[0016] Please see attached Figure 1-2 The utility model provides a quick-release marble pin, which includes a pin body 1, a pin cover 2, and a plurality of marbles 3. The circular diameter of the pin cover is equal to the circular diameter of the pin body. Preferably, the circular diameter of the pin cover is equal to the circular diameter of the pin body to improve the surface flatness of the connection between the two after assembly. The pin cover 2 is connected to the lower end of the pin body 1 and forms an installation cavity 4 therewith. The side wall of the pin body 1 is provided with a marble groove 5 connected to the installation cavity 4. The marble is arranged in the marble groove and at least a part of it can protrude from the marble groove. A spring member 6 and a marble reset member 7 that resists the marble are provided in the installation cavity 4. The spring member 6 is used to keep the marble reset member 7 resisting the marble 3. The marble reset member 7 is provided with an operating rod 71 extending out of the installation cavity. Under normal conditions, the spring part elastically resists the marble reset part so that the marble protrudes from the ejection slot. The user applies force to the operating rod to press the marble reset part downward and compress the spring part. The marble loses the resisting effect of the marble reset part and can be easily retracted into the pin shaft body, making it convenient for the user to install and remove the marble pin shaft. When the marble of the marble pin shaft is damaged and affects its extension and retraction, the pin shaft cover can be removed to take out the marble and replace it.

[0017] The marble reset member 7 is a reset disk, and the outer edge of the reset disk is in an arc shape 72. The outer edge of the reset disk is used to support the marble so that the marble protrudes out of the marble groove. The outer edge of the reset disk is designed to be in an arc shape, which can fit the surface of the marble, so that the reset disk can apply force to the marble to pop it out of the marble groove more smoothly.

[0018] The operating rod 71 is arranged at the top and in the middle of the reset disk, and the pin shaft body is provided with a channel 8 for the operating rod to extend, so that the user can directly press the operating rod to apply force to the reset disk. When the user needs to insert or pull out the pin shaft, the user presses the operating rod to make the marble lose its holding force and the marble can be easily retracted.

[0019] The number of the marbles 3 is more than three, and three marble grooves 5 are distributed circumferentially on the side wall of the pin shaft body 1. A marble is placed in each marble groove. The more marbles there are, the lower the possibility of the pin shaft loosening. The number of marbles can be selected according to actual needs.

[0020] The marble reset member 7 and the pin cover 2 are both provided with a boss 9, and the boss is sleeved by the spring member to position the spring member and prevent the spring from being twisted and displaced due to force.

[0021] The pin cover 2 is provided with a guide shaft 10 for inserting the marble reset member 7. The marble reset member has a hole 11 that cooperates with the guide shaft. With the cooperation of the guide shaft and the hole, it can be ensured that the marble reset member maintains coaxiality during reciprocating motion to avoid displacement.

[0022] The inner side of the pin shaft body 1 is provided with an internal thread structure, and the pin shaft cover 2 is provided with an external thread structure matching the internal thread structure. The pin shaft body and the pin shaft cover are assembled using the thread structure, which has the advantages of easy installation and disassembly.

[0023] 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.
