Description

Technical Field

[0001] The utility model relates to the technical field of self-closing valve accessories, in particular to a control switch for a gas switch box. Background Art

[0002] For concealed gas valves, the valve body is typically installed in a switch box embedded in the wall. Due to the inaccurate depth of the switch box or the varying thickness of the exterior finish (cement, ceramic tile), it can be challenging to secure the knob through the switch box cover and securely connect it to the valve body. A common solution is to add a depth-adjustable mounting plate to the valve body, which mounts the valve body to this plate. This undoubtedly increases the complexity of production and processing. Furthermore, the depth of the mounting plate must be adjusted during installation, which is a time-consuming operation.

[0003] Therefore, the prior art currently has a Chinese utility model patent with publication number CN210600408U, entitled "A Gas Switch Box Control Structure." This invention, without changing the existing valve body's structural design, features an adapter rod that can adapt to varying valve body installation depths. Its plug-in, removable fastening reduces the difficulty of removing the knob. The elastic snap-fit ​​between the knob and the upper connector is more stable and secure than a direct interference fit. The adapter rod in this control structure merely extends the knob-to-valve body connection, requiring careful attention to the valve body's installation depth within the switch box. Otherwise, a fixed-length adapter rod would still be inadequate. Furthermore, multiple adapter rods of varying lengths would be necessary to accommodate on-site installation. This increases installation costs and hinders smooth and quick installation. Furthermore, the outer side of the elastic buckle within the knob lacks support. When the knob is in use, when the buckle is subjected to significant force, it can easily exceed its bearing capacity, resulting in permanent deformation. This can cause the knob to wobble or even fall off the adapter rod, making it unstable. Utility Model Content

[0004] The purpose of the utility model is to provide a control switch for a gas switch box, so as to solve the problems of the existing gas switch box control structure having high installation cost, not being smooth and fast, and the knob thereon being unstable in use.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A control switch for a gas switch box includes a switch box for a self-closing valve on a gas pipeline, the switch box being equipped with a control switch for the self-closing valve, the control switch including a knob, an adjusting rod and a valve sleeve arranged in sequence from top to bottom, the knob and the adjusting rod being slidably connected and an elastic member being provided in a sliding gap, the adjusting rod and the valve sleeve being sleeved together and fixed therebetween by a first screw, the flange on the adjusting rod being pressed by a box cover of the switch box, and the valve sleeve being adapted to the valve stem of the self-closing valve.

[0007] A further technical solution is: the elastic member is a U-shaped spring sheet.

[0008] A further technical solution is: the outer end of the elastic member is fixed to the knob by a second screw.

[0009] A further technical solution is: a groove for accommodating the U-shaped spring piece is provided in the knob.

[0010] A further technical solution is that: the regulating rod and the valve sleeve are both provided with a plurality of threaded holes that match each other along their respective axial directions.

[0011] A further technical solution is that the cross sections of the knob and the adjusting rod are both polygonal.

[0012] A further technical solution is that a transverse surface is provided on the outer peripheral surface of the knob.

[0013] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0014] This utility model provides a control switch for a gas switch box. The adjustment rod and valve sleeve, in combination, can be adjusted within a certain length range to accommodate the varying depths of the self-closing valve within the switch box. This ensures that the knob, through the adjustment rod and valve sleeve, can smoothly control the opening and closing of the self-closing valve. Furthermore, an elastic member is installed between the adjustment rod and knob to prevent the knob and adjustment rod from shaking or becoming detached. Furthermore, the back of the elastic member has a support to prevent it from exceeding its elastic deformation range. This switch is stable, reliable, and easy to install.
