Description

Fastener convenient to maintain

Technical Field

The utility model belongs to the technical field of fasteners, and particularly relates to a fastener convenient to maintain.

Background

The fastener is a general name of a type of mechanical parts adopted when two or more parts (or components) are fastened and connected into a whole, and is widely applied to various machines, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical engineering, instruments, supplies and the like. At present, the requirement of people on the safety of equipment is higher and higher, and a large amount of public facility property and personal safety loss is caused by the looseness of a mechanical component connection part every year.

The existing fastener is likely to loose due to the external environment in the use process, and installation tools need to be carried during installation, so that the use and maintenance are not very convenient.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides the fastening piece which is convenient to maintain, can effectively prevent loosening and is convenient to use and maintain.

The purpose of the utility model can be realized by the following technical scheme: a fastener convenient to maintain comprises a head part and a rod part, wherein the head part is transversely provided with a slot, the bottom end and the upper part of the slot are respectively provided with a clamping groove, a rotating rod is inserted into the slot, and the bottom end of the rotating rod is provided with an elastic clamping block matched with the clamping groove; the pole portion is opened has a plurality of through-holes, form the standing groove between the through-hole, be equipped with conflict mechanism in the standing groove, conflict mechanism includes well core rod, it has branch to articulate on the well core rod, the end connection of branch has the conflict piece, the conflict piece is located through-hole department, well core rod's top is passed the head and is stretched out the head.

Furthermore, the supporting rods are symmetrically distributed by taking the central rod as a center.

Furthermore, the clamping groove and the elastic clamping block are hemispherical.

Furthermore, the contact part is a circular arc-shaped plate capable of elastically deforming.

Furthermore, when the collision piece is in a working state, the upper end surface of the central rod and the upper end surface of the head are positioned on the same horizontal plane.

The utility model has the beneficial effects that:

1. the head of the utility model is transversely provided with the slot, the rotating rod is inserted into the slot, and the utility model does not need to carry an installation tool during installation and is convenient to use and maintain.

2. The rod part of the utility model is provided with the abutting mechanism, and the abutting part of the abutting mechanism abuts against an object to be fastened after the installation is finished, so that the looseness can be effectively prevented, and the safety and the stability are higher.

Drawings

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of a use state of the present invention.

In the figure: 1. a head portion; 2. a rod portion; 3. a slot; 4. a card slot; 5. rotating the rod; 6. an elastic clamping block; 7. a through hole; 8. a placement groove; 9. a center pole; 10. a strut; 11. a contact part.

Detailed Description

The utility model is further described below with reference to the accompanying drawings: as shown in fig. 1 to 2 of the drawings of the specification, a fastener convenient for maintenance comprises a head portion 1 and a rod portion 2, wherein the head portion 1 is transversely provided with a slot 3, the bottom end and the upper portion of the slot 3 are respectively provided with a clamping slot 4, a rotating rod 5 is inserted into the slot 3, and the bottom end of the rotating rod 5 is provided with an elastic clamping block 6 matched with the clamping slot 4; the utility model discloses a supporting device for the automobile seat, including pole portion 2, through-hole 1, supporting piece 10, supporting piece 11, head 1, pole portion 2 is opened has a plurality of through-holes 7, form standing groove 8 between the through-hole 7, be equipped with conflict mechanism in the standing groove 8, conflict mechanism includes well core rod 9, articulated on well core rod 9 have branch 10, the end connection of branch 10 has conflict piece 11, conflict piece 11 is located through-hole 7 department, the top of well core rod 9 is passed head 1 and is stretched out head 1.

Furthermore, the supporting rods 10 are symmetrically distributed with the central rod 9 as the center.

Furthermore, the clamping groove 4 and the elastic clamping block 6 are both hemispherical.

Further, the contact element 11 is an elastically deformable circular arc-shaped plate.

Further, when the contact element 6 is in an operating state, the upper end surface of the central rod 10 and the upper end surface of the head 1 are located on the same horizontal plane.

The use principle is as follows:

as shown in fig. 1, the rotating rod 5 is located outside the head portion 1, the elastic latch 6 is located in the upper latch slot 4, the interference mechanism is not operated, the end portion of the central rod 10 is located outside the head portion 1, and the interference member 12 is located in the through hole 7, which does not hinder the rotation of the present invention. The utility model can be installed in place by rotating the rotating rod 5 without carrying an installation tool, and is convenient to use and maintain.

As shown in fig. 2, after the rotating rod 5 is installed in place, the rotating rod is pushed into the slot 3, and the elastic latch 6 is located in the slot 4 at the bottom. Pressing center core rod 10, center core rod 10 drives branch 11 motion, and conflict piece 6 is the circular arc shaped plate that can take place elastic deformation. Branch 11 makes contact 7 take place elastic deformation, contradicts with the article that need the fastening, can effectively prevent not hard up, and security and stability are higher. At this time, the upper end surface of the center rod 10 and the upper end surface of the head 1 are located on the same horizontal plane, and the external appearance is not affected.

The foregoing is merely exemplary and illustrative of the present invention, and various modifications, additions and substitutions of the specific embodiments described herein may be made by those skilled in the art without departing from the scope of the utility model as defined in the accompanying claims.
