Detailed Description

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

The embodiment of the utility model discloses a combined fastener.

Referring to fig. 1 and 2, the combined fastener comprises at least two bodies 1 and washers 2 respectively sleeved on the bodies 1, wherein the washers 2 are made of plastics with certain elastic deformation capability. A polish rod part 10 is formed at one end of the body 1 close to the head of the body, a plurality of slots 11 are formed in the outer side wall of the polish rod part 10, and the slots 11 circumferentially uniformly surround the outer circumferential surface of the polish rod part 10 at intervals.

As shown in fig. 2 and 3, a plurality of inserting pieces 20 for being inserted into corresponding slots 11 are integrally formed on the inner side wall of the gasket 2, the number of the inserting pieces 20 corresponds to the number of the slots 11 one by one, and the inserting pieces 20 are circumferentially uniformly spaced around the inner side wall of the gasket 2. The length direction of the inserting piece 20 extends along the radial direction of the gasket 2, a plurality of inserting holes 21 which are sequentially and uniformly arranged on the gasket 2 at intervals are also penetrated through the gasket 2, the inserting holes 21 are circumferentially distributed around the central axis of the gasket 2, and the central axis of the inserting holes 21 is parallel to the central axis of the gasket 2.

As shown in fig. 2 and 3, the gasket 2 is detachably provided with a connecting strip 3 for connecting adjacent gaskets 2 through a jack 21, and the length of the connecting strip 3 can be selected according to actual use requirements. The connection bar 3 is provided at both ends with the insertion block 30 for passing through the insertion hole 21, and the maximum diameter of the insertion block 30 is larger than the inner diameter of the insertion hole 21. Since the gasket 2 is made of plastic having a certain elastic deformability, it is ensured that the insert 30 can pass smoothly through the insertion hole 21. Once the end of the insert 30 passes through the insertion hole 21 smoothly, the inner diameter of the insertion hole 21 will shrink and recover, and at this time, the connection bar 3 end and the respective opposite washers 2 can be connected and fixed under the limit of the insert 30 because the maximum diameter of the insert 30 is larger than the inner diameter of the insertion hole 21.

By providing a plurality of insertion holes 21, the insertion block 30 can be smoothly inserted into the insertion hole 21 at a proper position, and the connection work of the multi-aspect gasket 2 can be satisfied.

The inserting pieces 20 on the gasket 2 are respectively inserted into the corresponding inserting grooves 11, and the gasket 2 can synchronously rotate along with the body 1 through mutual inserting cooperation of the inserting pieces 20 and the inserting grooves 11. After the body 1 is screwed on the surface of the connecting piece, the two ends of the connecting strip 3 are respectively arranged on the gaskets 2 of the adjacent bodies 1, and at the moment, the gaskets 2 at the two ends can be effectively limited to rotate under the action of the connecting strip 3. Along with the rotation of the gasket 2 limited by the connecting strip 3, the rotation of the body 1 can be further limited at this time, a better anti-loosening effect is achieved on the body 1, and the fastening effect of the body 1 is enhanced. When the body 1 is required to be unscrewed from the connecting piece, the connecting strip 3 is only required to be detached from the gasket 2, and the body 1 can be smoothly rotated at the moment.

As shown in fig. 2 and 3, the inner side wall of the slot 11 is provided with a guiding inclined plane 12, and the guiding inclined plane 12 is located on the rotating path of the insert 20 when the insert 20 rotates relative to the body 1. The guide bevel 12 can be used to guide the removal of the insert piece 20 from the slot 11 when screwing the body 1. When the connecting strip 3 connects two adjacent washers 2, in order to ensure that the body 1 can be more stably and firmly screwed on the connecting piece, the body 1 can be further screwed, and the inserting piece 20 can be guided to be smoothly moved out of the original slot 11 under the action of the guiding inclined plane 12 along with the rotation of the body 1 during screwing, so that the smooth rotation of the body 1 can be ensured under the condition of not dismantling the connecting strip 3. After the body 1 is screwed, the inserting piece 20 is inserted into the inserting groove 11 at the corresponding position again, and at the moment, the anti-falling effect of the body 1 can be ensured under the combined action of the gasket 2 and the connecting strip 3.
