[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a dustproof guide pin with positioning effect.

[0004] The objective of this utility model can be achieved through the following technical solution: A dustproof guide pin, comprising a guide pin seat, characterized in that the guide pin seat is provided with a positioning rod for positioning, the guide pin seat has an installation space for installing the positioning rod, and the positioning rod can retract in the installation space, one end of the positioning rod extends out of the guide pin seat and is connected to a handle for controlling the positioning rod, both sides of the guide pin seat are provided with sliding parts for fixing the positioning rod, and the sliding parts can slide up and down on both sides of the guide pin seat, the positioning rod is provided with a positioning part relative to the installation space, a connecting spring is provided between the positioning part and the guide pin seat, a ball is slidably provided between the positioning part and the sliding part, the sliding part has a first locking groove that matches the ball and a second locking groove that matches the ball.

[0005] In the aforementioned dustproof guide pin, both sides of the guide pin seat are provided with sliding grooves for the sliding part to slide up and down, and a reset spring is provided in the sliding groove for the sliding part to return to its original position.

[0006] In the aforementioned dustproof guide pin, both sides of the guide pin seat are provided with fixing parts, and the fixing parts are provided with threaded through holes.

[0007] Compared with existing technologies, this dustproof guide pin can be retracted on the guide pin seat by the positioning rod, and can be used for guiding and positioning different workpieces. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] Figure 2This is a cross-sectional structural diagram of the present invention.

[0010] In the diagram, 1. Guide pin seat; 2. Positioning rod; 3. Installation space; 4. Handle; 5. Sliding part; 6. Positioning part; 7. Connecting spring; 8. Ball bearing; 9. Snap-fit ​​groove one; 10. Snap-fit ​​groove two; 11. Return spring; 12. Fixing part. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this dustproof guide pin includes a guide pin seat 1, on which a positioning rod 2 for positioning is provided. The guide pin seat 1 has an installation space 3 for installing the positioning rod 2, and the positioning rod 2 can retract in the installation space 3. One end of the positioning rod 2 extends out of the guide pin seat 1 and is connected to a handle 4 for controlling the positioning rod 2. Both sides of the guide pin seat 1 are provided with sliding parts 5 for fixing the positioning rod 2, and the sliding parts 5 can slide up and down on both sides of the guide pin seat 1. The positioning rod 2 is provided with a positioning part 6 relative to the installation space 3. A connecting spring 7 is provided between the positioning part 6 and the guide pin seat 1. A ball bearing 8 is slidably arranged between the positioning part 6 and the sliding part 5. The sliding part 5 has a first locking groove 9 that matches the ball bearing 8, and a second locking groove 10 that matches the ball bearing 8.

[0013] To elaborate further, when the positioning rod 2 needs to be retracted into the installation space 3, the sliding part 5 is pressed down, the return spring 11 is compressed, the locking groove 9 of the sliding part 5 engages with the ball 8, and one end of the ball 8 can extend into the locking groove 9, releasing the positioning of the positioning rod 2 in the installation space 3. Pulling the handle 4 moves the positioning part 6 upward to a certain position, releasing the sliding part 5, causing the return spring 11 to rebound, and one end of the ball 8 extends out of the rolling groove and abuts against the lower end of the positioning part 6, thereby positioning the positioning part 6, and one end of the positioning rod 2 is retracted into the installation space 3. When the positioning rod 2 needs to be extended, the sliding part 5 is pressed down, the locking groove 9 of the sliding part 5 engages with the ball 8, and one end of the ball 8 can extend into the locking groove 9, the connecting spring 7 rebounds, and the positioning rod 2 extends out of the installation space 3 again for guiding and positioning.

[0014] To elaborate further, both sides of the guide pin seat 1 are provided with sliding grooves for the sliding part 5 to slide up and down, and a return spring 11 is provided in the sliding groove for the sliding part 5 to return to its original position.

[0015] To elaborate further, both sides of the guide pin seat 1 are provided with fixing parts 12, and the fixing parts 12 are provided with threaded through holes.

[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as guide pin 1, positioning rod 2, mounting space 3, handle 4, sliding part 5, positioning part 6, connecting spring 7, ball 8, snap-fit ​​groove 1 9, snap-fit ​​groove 2 10, return spring 11, and fixing part 12, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
