Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of threaded fastener, especially to a fastener with sealing reinforced surrounding edge. BACKGROUND

[0002] When the hose is connected with other pipes, a special connecting piece is provided with a fastener with internal thread, and the fastener is used for positioning and clamping the hose. For example, a hose connecting device is disclosed in Chinese patent CN214662789U, which comprises a connecting piece and a fastener mounted on the connecting piece. The connecting piece has a first external thread pipe, a second external thread pipe and a conical pipe connected in sequence. The first external thread pipe, the second external thread pipe and the conical pipe are connected in sequence. The diameter of the second external thread pipe is larger than that of the conical pipe. The conical pipe has a first connecting end for the hose to be sleeved and a second connecting end connected with the second external thread pipe. The outer diameter of the conical pipe gradually increases from the first connecting end to the second connecting end. The fastener is provided with an internal thread hole and a pipe insertion hole for the hose to pass through. The pipe insertion hole is in communication with the internal thread hole. The fastener is screwed with the second external thread pipe through the internal thread hole. The hose is sleeved on the conical pipe and clamped between the inner wall of the pipe insertion hole and the outer circumferential side surface of the conical pipe.

[0003] In the above-mentioned prior art solution, when the hose is clamped between the inner wall of the pipe insertion hole of the fastener and the outer circumferential side surface of the conical pipe, the fastener made of metal material is opaque, which makes it difficult to determine the length of the hose clamped inside the fastener, affecting the connection quality of the hose.

[0018] As described above, due to the adoption of the above technical solutions, the present application has the following beneficial effects:

[0019] 1. In the present application, when the hose is connected to other pipes through the special connecting piece, the fastener rotates to extrude the hose, the arc-shaped notch forms a protruding sealing reinforcing surrounding edge on the pipe body, the arc-shaped notch on both sides of the pipe body can show the length of the hose inserted into the pipe body, and the number of the corresponding marking grooves of the hose can be used to accurately determine the length of the hose inserted into the pipe body.

[0020] 2. In the present application, the inner wall of the pipe body is further provided with a plurality of anti-skid protrusions arranged in a circumferential direction, the anti-skid protrusions further extrude the hose when the pipe body rotates to extrude the hose, preventing the hose from being separated from the fastener, and realizing the sealing reinforcement of the hose splicing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-2 This utility model provides a technical solution: a fastener with a sealing and reinforcing edge, comprising:

[0029] The tube body 1 has an internal thread 11 on its inner wall and an arc-shaped notch 12 on one of the opposite side walls of the tube body 1, which extends inward from the end face of the tube body 1.

[0030] Marking groove 2 is provided on the surface of pipe body 1, and several marking grooves 2 are arranged equidistantly along a straight line on the surface of pipe body 1.

[0031] The marking groove 2 is a circular groove, which makes it easy to distinguish between two adjacent marking grooves 2 and accurately determine the length of the hose extending into the tube body 1.

[0032] Working principle: When the hose is connected to other pipes through a special connector, the fastener rotates and squeezes the hose, and the arc-shaped notch 12 forms a protruding sealing reinforcement edge on the pipe body 1. The arc-shaped notches 12 on both sides of the pipe body 1 can show the length of the hose extending into the pipe body 1, and the length of the hose extending into the pipe body 1 can be accurately determined by the number of the corresponding marking grooves 2 of the hose.

[0033] Example 2

[0034] This embodiment further improves upon the above embodiment by providing the following technical solution: Several circumferentially arranged anti-slip ribs 4 are provided on the inner wall of the tube body 1. When the tube body 1 rotates and squeezes the hose, the anti-slip ribs 4 further compress the hose, preventing it from detaching from the fasteners and thus enhancing the sealing of the hose joint.

[0035] In addition, the anti-slip ribs 4 are arranged at an angle. The anti-slip ribs 4 increase the locking effect when the tube body 1 rotates in the forward direction to squeeze the hose, and at the same time increase the resistance of the tube body 1 rotating in the reverse direction to prevent the fasteners from loosening, thereby further enhancing the sealing of the hose splice.

[0036] Example 3

[0037] Based on the above embodiments, this embodiment further improves upon the following technical solution: a plurality of anti-slip grooves 3 are arranged circumferentially on the outer wall of the pipe body 1, and the anti-slip grooves 3 are strip-shaped grooves.

[0038] Anti-slip groove 3 increases the surface roughness of the fastener, making it easier to rotate the fastener to lock the hose.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
