Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure reducers, in particular to a quick connector device based on gas pressure reducer calibration. Background Art

[0002] A gas pressure reducer is a regulating device that reduces high-pressure gas to low-pressure gas and keeps the pressure and flow of the output gas stable. Figure 1 and Figure 2 As shown, the gas pressure reducer includes a main body and an air inlet end provided on one side of the main body, a threaded sleeve is rotatably provided on the outside of the air inlet end, the gas source is usually mainly stored in a gas cylinder, the top of the gas cylinder is connected to a control valve, the control valve includes a valve body and an air outlet end provided on one side of the valve body, the surface of the air outlet end is provided with an external thread that matches the threaded sleeve, when installing, it is necessary to align one end of the air inlet end with the air outlet end, and align the threaded sleeve with the air outlet end at the same time, then hold the main body with one hand to keep it from shaking, and rotate the threaded sleeve with the other hand, so that the threaded sleeve moves along the air outlet end until the air inlet end is fully in contact with the air outlet end.

[0003] According to the above installation steps, it can be seen that the existing gas pressure reducer has only one air inlet end that needs to be connected to the air outlet end of the control valve, and the gas pressure reducer does not have a structure that can maintain its balance. Therefore, during the installation process, it is necessary to manually keep the main body from rotating and shaking to prevent the installation failure caused by the deviation of the threaded sleeve of the gas pressure reducer and the air outlet end of the control valve from the expected position. Not only is the operation cumbersome, but the gas pressure reducer will also be skewed after installation, making it more inconvenient to connect to the gas-using equipment later. Utility Model Content

[0004] In view of this, the purpose of the present invention is to propose a quick connector device based on gas pressure reducer calibration to solve the technical problems that the existing gas pressure reducer needs to be manually balanced during installation and is prone to tilting after installation.

[0005] Based on the above objectives, the utility model provides a quick connector device based on gas pressure reducer calibration, comprising:

[0006] A support member with one end provided on the gas pressure reducer;

[0007] A limit member connected to the support member at one end, and a limit structure for contacting the control valve at the other end of the limit member, thereby forming at least two fixations for the gas pressure reducer on the movable surface on which the gas pressure reducer rotates around the control valve. When in use, the position of the limit member is adjusted so that its limit structure contacts the control valve to limit the rotation of the gas pressure reducer around the control valve.

[0008] As a preferred technical solution of the present invention, the limiting structure is a limiting groove provided on the surface of the limiting member.

[0009] As a preferred technical solution of the present invention, a sliding groove is provided inside the support member, a sliding rod is slidably provided in the sliding groove, and the limiting member is connected to the sliding rod.

[0010] As a preferred technical solution of the present invention, the total length of the limit member and the slide rod is greater than the distance between the gas pressure reducer and the control valve.

[0011] As a preferred technical solution of the present invention, the joint device further comprises a threaded rod, which is threadedly connected to a thread groove extending through the surface of the support member, and one end of the threaded rod abuts against the surface of the sliding rod.

[0012] As a preferred technical solution of the present invention, the connector device further includes:

[0013] a rotating shaft connected to the support member;

[0014] A bracket is connected to the main body of the gas pressure reducer at one end, and the bracket is provided with a rotation groove, and the rotation groove is rotatably matched with the rotating shaft.

[0015] As a preferred technical solution of the present invention, a fixing plate is provided at one end of the rotating shaft, a washer is provided on the rotating shaft sleeve, and a spring is provided between the fixing plate and the washer.

[0016] As a preferred technical solution of the present invention, the inner wall of the sliding groove is provided with a guide protrusion, and the guide protrusion is slidably matched with the guide groove provided on the surface of the sliding rod.

[0017] As a preferred technical solution of the present invention, a card slot is provided on the main body of the gas pressure reducer, and the shape of the card slot is consistent with the shape of the support member.

[0018] As a preferred technical solution of the present invention, the limiting groove is an arc-shaped groove, and the arc-shaped groove matches the shape of the valve stem on the valve body of the control valve.

[0019] The beneficial effects of the present invention are as follows: a support is provided on the gas pressure reducer, and the support is telescopically connected to the limit member. During installation, the position of the limit member is adjusted so that the limit structure on its surface contacts the control valve. When the threaded sleeve of the gas pressure reducer is aligned with the gas outlet end of the control valve and rotates, the limit structure fixes the gas pressure reducer at two locations on the movable plane where the gas pressure reducer rotates around the control valve, preventing the gas pressure reducer from rotating and shaking, ensuring the uniqueness of the installation position, and facilitating the subsequent gas-using equipment to be connected to the gas pressure reducer.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 and Figure 2 As shown, a quick connector device based on gas pressure reducer calibration includes:

[0030] A support member 11 having one end provided on the gas pressure reducer;

[0031] A stopper 13 is connected to the support member 11 at one end, and the other end of the stopper 13 has a stopper structure for contacting the control valve, thereby forming at least two fixations on the movable surface of the gas pressure reducer rotating around the control valve. When in use, the position of the stopper 13 is adjusted so that the stopper structure contacts the control valve, thereby limiting the rotation of the gas pressure reducer around the control valve.

[0032] The above technical solution can prevent the gas pressure reducer from rotating and shaking during installation. When in use, adjust the position of the limit member 13 so that the limiting structure on the limit member 13 contacts the control valve on the gas cylinder 4, align the threaded sleeve 3 of the gas pressure reducer with the gas outlet end 7 of the control valve, rotate the threaded sleeve 3 so that its internal thread rotates around the external thread on the surface of the gas outlet end 7, so that the gas inlet end 2 moves toward the gas outlet end 7 until the two fit together. In this process, due to the presence of the upper limit structure of the limit member 13, the gas pressure reducer is fixed at two places on the movable plane where the gas pressure reducer rotates around the control valve, thereby cooperating with the threaded sleeve 3 and the gas outlet end 7 to prevent the gas pressure reducer from rotating and shaking.

[0033] like Figure 2 and 3 As shown, in this embodiment, the limiting structure is a limiting groove 14 provided on the surface of the limiting member 13; specifically, the limiting groove 14 is an arc-shaped groove, which matches the shape of the valve stem 6 on the control valve body 5;

[0034] The above technical solution can prevent the gas pressure reducer from rotating during installation. When in use, the limiting groove 14 on the surface of the limiting member 13 is aligned with the valve stem 6 on the valve body 5 and inserted, so that the limiting groove 14 and the valve stem 6 can fit together, ensuring that the gas pressure reducer always remains stable during the rotation of the threaded sleeve 3.

[0035] like Figure 5 As shown, in this embodiment, a slide groove is provided inside the support member 11, a slide rod 12 is slidably provided in the slide groove, and a limit member 13 is connected to the slide rod 12; the total length of the limit member 13 and the slide rod 12 is greater than the distance between the gas pressure reducer and the control valve; a guide protrusion 15 is provided on the inner wall of the slide groove, and the guide protrusion 15 is slidably engaged with a guide groove 16 provided on the surface of the slide rod 12;

[0036] The above technical solution can adjust the length between the limit member 13 and the support member 11 by sliding. By setting a sliding rod 12 connected to the limit member 13, the sliding rod 12 can slide in the sliding groove of the support member 11 to adjust the position of the limit member 13 and ensure that the limiting groove 14 of the limit member 13 can contact the valve stem 6.

[0037] like Figure 3 As shown, in this embodiment, the joint device further includes a threaded rod 17, which is threadedly connected to a threaded groove 18 extending through the surface of the support member 11, and one end of the threaded rod 17 contacts the surface of the slide rod 12;

[0038] The above technical solution can prevent the sliding rod 12 and the sliding groove of the support member 11 from being too loose. When in use, the threaded rod 17 is rotated to make it contact with the surface of the sliding rod 12, ensuring that the sliding rod 12 has a damping effect when sliding in the sliding groove of the support member 11, preventing the sliding rod 12 from retracting into the sliding groove of the support member 11 due to accidental touch when calibrating and installing the gas pressure reducer.

[0039] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the connector device further includes:

[0040] A rotating shaft 10 connected to a support member 11;

[0041] A bracket 8 is connected to the main body 1 of the gas pressure reducer at one end. The bracket 8 is provided with a rotation groove 9, which is rotatably matched with the rotating shaft 10. A card slot 22 is provided on the main body 1 of the gas pressure reducer. The shape of the card slot 22 is consistent with the shape of the support member 11.

[0042] The above technical solution can facilitate the folding of the support member 11. After the installation is completed, the slide rod 12 is retracted into the slide groove of the support member 11 to ensure that the limit member 13 is out of contact with the valve stem 6. The support member 11 is rotated so that its rotating shaft 10 rotates around the rotating groove 9 of the bracket 8 until the support member 11 is embedded in the card slot 22. The folding is completed and the volume of the device is reduced.

[0043] like Figure 4 As shown, in this embodiment, a fixing plate 19 is provided at one end of the rotating shaft 10, a washer 21 is sleeved on the rotating shaft 10, and a spring 20 is provided between the fixing plate 19 and the washer 21;

[0044] The above technical solution can provide a damping effect on the rotation of the support member 11 to prevent the support member 11 from rotating due to accidental touch. By setting the spring 20, the spring 20 can push the washer 21 to contact the bracket 8, so that the support member 11 and the bracket 8 are tightened, and then friction is generated to prevent the support member 11 from loosening.

[0045] The working principle is as follows: by pulling the limit piece 13, the slide rod 12 is driven to slide out of the slide groove of the support piece 11, and the position of the limit piece 13 is adjusted so that the limit groove 14 on the limit piece 13 contacts the valve stem 6 of the control valve, and the threaded rod 17 is rotated to make it contact with the surface of the slide rod 12, ensuring that the slide rod 12 has a damping effect when sliding in the slide groove of the support piece 11, preventing the slide rod 12 from retracting into the slide groove of the support piece 11 due to accidental touch, aligning the threaded sleeve 3 of the gas pressure reducer with the gas outlet end 7 of the control valve, and rotating the threaded sleeve 3 so that its internal thread rotates around the external thread on the surface of the gas outlet end 7, thereby making the gas inlet end 2 move toward the gas outlet end 7 until the two fit together. In this process, the slide rod 12 is gradually retracted into the slide groove of the support piece 11, so that the limit groove 14 of the limit piece 13 is always in contact with the valve stem 6, forming two fixations for the gas pressure reducer on the movable plane where the gas pressure reducer rotates around the control valve, thereby cooperating with the threaded sleeve 3 and the gas outlet end 7 to prevent the gas pressure reducer from rotating and shaking;

[0046] After the installation is completed, retract the slide rod 12 into the slide groove of the support member 11, ensure that the limit member 13 is out of contact with the valve stem 6, rotate the support member 11 so that its rotating shaft 10 rotates around the rotating groove 9 of the bracket 8 until the support member 11 is embedded in the card slot 22, and the folding is completed to reduce the volume of the device.
