Description

Technical Field

[0001] This utility model relates to a cap connector, specifically a stress-relieving cap. Background Technology

[0002] In existing technologies, valve caps are generally snap-fitted onto the valve body. For example, patent number CN214367969U, titled "A Check Valve with a Protective Sleeve Structure," typically uses an interference fit to prevent detachment after installation. Therefore, when the valve cap is installed onto the valve body, the pressure during compression can cause either the cap or the valve body to crack, rendering the connector unusable. To address this, a stress-relieving valve cap is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a stress-relieving cap in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stress-relieving cap, comprising a cap, characterized in that the cap has at least one opening groove for preventing damage during installation due to the inability to release stress.

[0005] A further preferred embodiment includes a clamping claw mounted on the clamping cap and an anti-detachment section disposed at the end of the clamping cap to change the position of the clamping claw and thus improve the stability of the pipe installation.

[0006] More preferably, one side of the anti-detachment section is provided with a guide surface that guides the claw to rotate and move onto the anti-detachment section.

[0007] A further preferred embodiment includes a limiting end located at the other end of the anti-detachment section to limit the rotational position of the chuck.

[0008] A further preferred embodiment includes a rotating part disposed on the chuck to facilitate rotation of the chuck and to be adapted to the anti-detachment section.

[0009] A further preferred embodiment includes an arc-shaped positioning protrusion disposed on the anti-detachment section and an arc-shaped positioning groove disposed on the rotating part, which is adapted to the arc-shaped positioning protrusion and serves to limit the position of the rotating part on the anti-detachment section.

[0010] The beneficial effects of this utility model are: by setting several opening slots on the cap, the cap can be expanded to a certain extent when it is installed on the connector by snapping, thus avoiding damage to the connector or cap due to squeezing during installation;

[0011] The arc-shaped positioning protrusions and arc-shaped positioning grooves limit the position of the chuck, preventing leakage caused by rotation of the chuck. Attached Figure Description

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the stress-relieving cap of this utility model.

[0017] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] See Figures 1-3 As shown, a stress-relieving cap includes a cap 2, characterized in that the cap 2 is provided with at least one opening groove 5 for preventing the cap 2 from being damaged during installation due to the inability to release stress;

[0020] By setting several opening slots 5 on the cap 2, when the cap 2 is installed on the connector by snapping, it can expand to a certain extent through the opening slots 5 to release stress, thus avoiding damage to the connector or cap 2 due to squeezing during installation.

[0021] In one embodiment, it also includes a claw 4 mounted on the cap 2 and an anti-detachment section 6 disposed at the end of the cap 2 for changing the position of the claw 4 to change the pipe installation firmness;

[0022] It also includes a rotating part 7 that is provided on the chuck 4 to facilitate the rotation of the chuck 4 and is adapted to the anti-detachment section 6.

[0023] In one embodiment, a guide surface 61 is provided on one side of the anti-detachment section 6 to guide the claw 4 to rotate and move onto the anti-detachment section 6; the guide surface 61 guides the rotating part 7 when it rotates onto the anti-detachment section 6.

[0024] In one embodiment, it further includes a limiting end 62 disposed at the other end of the anti-detachment section 6 to limit the rotational position of the claw 4;

[0025] The setting of the limiting end 62 limits the rotation of the rotating part 7 to the position on the limiting end 62.

[0026] In one embodiment, it also includes an arc-shaped positioning protrusion 63 provided on the anti-detachment section 6 and an arc-shaped positioning groove 71 provided on the rotating part 7 that is adapted to the arc-shaped positioning protrusion 63 and plays a limiting role in the position of the rotating part 7 on the anti-detachment section 6.

[0027] The arc-shaped positioning protrusion 63 and the arc-shaped positioning groove 71 limit the positioning of the rotating part 7 on the anti-detachment section 6, preventing the chuck 4 from rotating and causing leakage. The arc shape makes it easy to move the arc-shaped positioning protrusion 63 into or out of the arc-shaped positioning groove 71.

[0028] When using this utility model: First, insert one end of the tube into the connector along the claw 4. After the tube is inserted into place, rotate the rotating part 7. The rotating part 7 drives the claw 4 to rotate until the arc-shaped positioning groove 71 on the rotating part 7 is locked onto the arc-shaped positioning protrusion 63 of the cap 2, and then the fixing is completed.

[0029] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
