Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a bolt with a gasket, as shown in fig. 1 and 3, a head part 1 and a rod part 2, wherein the head part 1 is fixedly connected with the rod part 2, one end of the head part 1, which is far away from the rod part 2, is provided with a first hexagonal groove 11, and part of the rod part 2 is provided with threads. The rod part 2 is sequentially sleeved with an elastic washer 3 and a round washer 4. The rod part 2 is provided with a limiting mechanism 5 which prevents the elastic washer 3 and the round washer 4 from separating from the rod part 2.

As shown in fig. 2 and 3, a movable groove 21 is formed along the axial direction of the rod 2 on the circumferential surface thereof, and an operation groove 22 is formed at the bottom of the movable groove 21. The circumferential surface of the rod part 2 far away from the direction of the movable groove 21 is provided with a fixing groove 23 communicated with the operation groove 22, the fixing groove 23 is in threaded connection with a fixing block 24 for sealing the fixing groove 23, and one end of the fixing block 24 far away from the operation hole is provided with a second hexagonal groove 241.

As shown in fig. 2 and 4, the limiting mechanism 5 includes a limiting block 51 fixedly connected to the inner circumferential surface of the circular washer 4, a spring 52 disposed in the fixing groove 23, and an operating lever 53 disposed in the operating groove 22. Two opposite side surfaces of the stopper 51 are respectively abutted against two opposite side walls of the movable groove 21. One end of the operation lever 53 is fitted into the movable groove 21, and the other end of the operation lever 53 is inserted into the fixed groove 23. One end of the side edge of the operating rod 53 close to the fixed block 24 is fixedly connected with a guide block 531, and the guide block 531 is positioned in the operating slot 22. Both ends of the spring 52 abut against the fixed block 24 and the operating lever 53, respectively. When the guide block 531 abuts on one end of the fixed groove 23 close to the operation groove 22, the operation lever 53 is fitted into the movable groove 21 but does not protrude beyond the outer surface of the lever 2.

As shown in fig. 2 and 3, a limiting protrusion 532 is fixedly connected to one end of the operating rod 53 close to the fixing block 24, and a part of the spring 52 is sleeved outside the limiting protrusion 532. The limiting protrusion 532 has a limiting effect, and has an effect of preventing the spring 52 from being positionally displaced when compressed or extended. The junction between the end of the operating rod 53 away from the operating slot 22 and the end of the operating rod 53 away from the head 1 is provided with a chamfer 533. The chamfer 533 facilitates the round washer 4 to be inserted between the head 1 and the operating rod 53 when the rod 2 and the round washer 4 are mounted.

As shown in fig. 1 and 4, a rubber pad 41 is fixedly connected to the bottom of the circular washer 4. When connecting the object with the bolt, the rubber pad 41 has an effect of preventing the circular washer 4 from contacting with the object, thereby preventing the circular washer 4 from being worn, and in addition, after the object is connected with the bolt, the rubber pad 41 is compressed, thereby increasing the stability of the connection of the object with the bolt.

As shown in fig. 1 and 2, the circumferential surface of the head 1 is fixedly connected with the anti-slip strip 12, which facilitates the manual operation of the bolt by a worker, so that the rod part 2 of the bolt part is firstly installed on an object.

The working principle is as follows: when changing elastic washer 3 and round washer 4, move the operation piece earlier and imbed in the operation groove 22, drive round washer 4 again in proper order, elastic washer 3 separates with pole portion 2, then establish pole portion 2 with 3 covers of new elastic washer, align stopper 51 and activity groove 21 at last, establish pole portion 2 outer and along the reverse one end of the axis of pole portion 2 with the round washer 4 cover, stopper 51 and chamfer 533 butt and drive operation pole 53 imbed in the operation groove 22, spring 52 compression deformation simultaneously. After the circular washer 4 passes through the movable slot 21, the spring 52 returns to drive the operating rod 53 to extend into the movable slot 21 until the guide block 531 abuts against one end of the fixed slot 23 close to the operating slot 22, thereby completing the replacement of the elastic washer 3 and the circular washer 4.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
