Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a fastener capable of rapid docking. Background Art

[0002] Fasteners are a general term for a type of mechanical parts used to fasten two or more parts or structures together to form a whole. Fasteners have a wide range of uses, and are commonly used in mechanical equipment, railway bridges, construction tools, etc. For example, on a construction site, we often need to build some iron racks to make auxiliary tools. These iron racks are built by fastening some steel pipes, rods, etc. together through fasteners. However, existing fasteners are troublesome whether they are used to build or dismantle iron racks. On construction sites, racks often need to be built and dismantled, which wastes a lot of time. Therefore, those skilled in the art provide a fastener that can be quickly docked to solve the problems raised in the above background technology. Summary of the invention

[0003] The purpose of the utility model is to provide a fastener that can be quickly connected to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A fastener that can be quickly connected includes a tube, a left locking sleeve and a right locking sleeve, wherein the left locking sleeve and the right locking sleeve are respectively sleeved on the tube, a left connecting end is arranged at the left end of the tube, and a right connecting end is arranged at the right end of the tube, and external threads are respectively provided on the outer circles of the left connecting end and the right connecting end.

[0006] As a further solution of the utility model: a plurality of movable grooves are respectively provided on the left butt joint end and the right butt joint end.

[0007] As a further solution of the utility model: the left end of the left butt joint end is fixedly connected with a left limiting ring, and the right end of the right butt joint end is fixedly connected with a right limiting ring.

[0008] As a further solution of the utility model: the left locking sleeve and the right locking sleeve are both internal thread sleeves, and internal threads are provided on the inner walls of the left locking sleeve and the right locking sleeve. The inner diameters of the left locking sleeve and the right locking sleeve are both larger at one end and smaller at the other end.

[0009] As a further solution of the utility model: a stopper is fixedly connected to an end surface of the left locking sleeve close to the left butt end and an end surface of the right locking sleeve close to the right butt end.

[0010] As a further solution of the utility model: a protective sleeve is sleeved on the outer circumference of the left locking sleeve and the right locking sleeve.

[0011] As a further solution of the utility model: a plurality of anti-slip strips are arranged on the protective cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, two rods are respectively inserted from the left butt end and the right butt end. Since both the left butt end and the right butt end are provided with movable grooves, a rod with a slightly larger diameter can be easily inserted. At this time, the rod and the left butt end and the right butt end are assembled by interference connection. Then, the left locking sleeve and the right locking sleeve are rotated to the left butt end and the right butt end respectively, so that the two rods can be locked, so that the two rods can be butt-jointed simply and quickly.

[0014] 2. The outer covers of the left locking sleeve and the right locking sleeve are provided with protective sleeves, which can protect the fasteners from corrosion. At the same time, the anti-slip strips above also play an anti-slip role, providing us with assistance when turning the left locking sleeve and the right locking sleeve.
