With the continuous development of the machine manufacturing industry, the requirements on the tooling process are higher and higher, and particularly, the parts are matched with the parts. At present, the cylindrical positioning pin is widely applied in China, but once the positioning pin is installed, the positioning pin is difficult to disassemble, and other parts are often damaged due to improper disassembly or forced disassembly.

SUMMERY OF THE UTILITY MODEL

The utility model provides a movable positioning pin for solving the defects and the defects of the prior art.

In order to achieve the purpose, the utility model adopts the technical proposal that: the utility model provides a movable positioning pin, includes sleeve, locating pin, the locating pin cup joints on the sleeve telescopically, be provided with the spacing groove on the sleeve, be provided with the locating part by the outside extension of spacing groove on the locating pin, the locating part with spacing groove joint is steerable the flexible of locating pin.

Preferably, the limiting groove is provided with a first limiting hole, and the limiting part is clamped with the first limiting hole to enable the positioning pin to extend out of the sleeve.

Preferably, the limiting groove is provided with a second limiting hole, and the limiting part and the second limiting hole are clamped to enable the positioning pin to be retracted into the sleeve.

Preferably, the limiting groove is in a shape of a Chinese character 'ao'.

Preferably, a through hole is formed in the locating pin, and the limiting member is inserted into the through hole.

Preferably, the stopper is a cylindrical handle.

Preferably, a spring is arranged in the sleeve and connected with the positioning pin.

The utility model has the advantages that:

the utility model provides a movable positioning pin through set up the locating pin that can freely stretch out and draw back in the sleeve, stretches out the sleeve with the locating pin during use, takes in the sleeve with the locating pin when not needing, and this not only has saved the man-hour of dismantling the locating pin, can not destroy other parts because of dismantling the locating pin moreover.

FIG. 2 is a schematic view of a pin extension of a removable pin;

FIG. 3 is a schematic view showing the pin retraction of a removable pin.

Detailed Description

The invention will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the invention, and the direction of the present embodiment is based on the direction of fig. 1.

As shown in fig. 1, a movable positioning pin includes a sleeve 1 and a positioning pin 2, the positioning pin 2 is telescopically sleeved on the sleeve 1, a limiting groove 11 is provided on the sleeve 1, a limiting member 21 extending outward from the limiting groove 11 is provided on the positioning pin 2, and the limiting member 21 is clamped with the limiting groove 11 to control the extension of the positioning pin 2. This design is through setting up locating pin 2 that can freely stretch out and draw back in sleeve 1, stretches out sleeve 1 with locating pin 2 during the use, takes in sleeve 1 with locating pin 2 when not needing, and this has not only saved the man-hour of dismantling locating pin 2, can not destroy other parts because of dismantling locating pin 2 moreover.

As shown in fig. 2, the limiting groove 11 is provided with a first limiting hole 111, and the limiting member 21 is engaged with the first limiting hole 111 to enable the positioning pin 2 to extend out of the sleeve 1. Therefore, when the positioning pin 2 is used, the positioning pin 2 can extend out of the sleeve 1 to be matched with other parts for use. And the design of the limit piece 21 and the first limit hole 111 clamping to extend the positioning pin 2 out of the sleeve 1 can fix the position of the positioning pin 2 to prevent the positioning pin from sliding so as not to be matched with other parts.

As shown in fig. 3, the limiting groove 11 is provided with a second limiting hole 112, and the limiting member 21 is engaged with the second limiting hole 112 to enable the positioning pin 2 to be retracted into the sleeve 1. Thus, the positioning pin 2 can be hidden in the sleeve 1 when not used, so that the whole positioning pin 2 does not need to be disassembled, and the labor is saved.

The limiting groove 11 is in a concave shape. The limiting member 21 slides in the limiting groove 11 to be clamped with the first limiting hole 111 and the second limiting hole 112. In addition, the limiting groove 11 can be in other shapes.

As shown in fig. 1, the positioning pin 2 is provided with a through hole 22, and the limiting member 21 is inserted into the through hole 22. When replacing the positioning pin 2, the limiting member 21 can be pulled out, and then the positioning pin 2 can be pulled out from the sleeve 1. The positioning pin 2 is simple and convenient to disassemble, and working hours are saved. Besides, a screw hole can be formed in the position of the positioning pin 2, a threaded structure is arranged at one end of the limiting member 21, and the limiting member 21 is installed on the positioning pin 2 through the matching of the threaded structure and the screw hole.

The limiting member 21 is a cylindrical handle. This facilitates handling during use. In addition, the stopper 21 may have another shape such as a hexagonal prism.

A spring 3 is arranged in the sleeve 1, and the spring 3 is connected with the positioning pin 2. When the limiting member 21 moves from the second limiting hole 112 to the first limiting hole 111, the spring 3 will give an assisting force to the positioning pin 2 to eject the sleeve 1, so that more manpower is saved when the positioning pin 2 is used. Besides, elastic silica gel can be arranged in the sleeve 1, and the positioning pin 2 is provided with assistance for popping out of the sleeve 1 through resilience of the elastic silica gel.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
