[0002] A pressure gauge adapter is a component used to connect pressure gauges of different types or specifications. It is usually made of metal, such as stainless steel, and comes in a variety of sizes and interface types to suit different application scenarios.

[0003] Among them, common pressure gauge adapters are installed by screwing on threads. This installation method is prone to rust and is inconvenient to open, or may cause problems such as thread slippage, affecting subsequent use. The overall use is inconvenient and needs to be further optimized.

[0004] Therefore, the present application provides a rotation-free installation adapter for a pressure gauge to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a rotation-free installation adapter for a pressure gauge to solve the problem that the existing pressure gauge adapter adopts a threaded installation method that is prone to later rust or thread slippage and is not convenient for normal use.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A non-rotating installation adapter for a pressure gauge, comprising an adapter tube for threadedly fixing the lower end of the pressure gauge, the lower end of the adapter tube being plugged with a butt tube, a vertical plug tube being fixed to the lower end of the adapter tube, a sealing ring being provided around the lower end of the plug tube, and positioning holes being symmetrically provided on both sides of the adapter tube;

[0008] The butt joint tube is plugged into and matched with the plug-in tube, a mounting block is fixed around the middle of the butt joint tube, a button is elastically mounted on the outer side of the mounting block, a movable cavity is opened in the mounting block, a tilting rod is rotatably mounted in the middle of the movable cavity, one end of the tilting rod is movably connected to the button, and the other end of the tilting rod is movably connected to a positioning column, the positioning column horizontally penetrates into the middle of the butt joint tube and is plugged into and matched with the positioning hole.

[0009] Optionally, a threaded portion is configured in the top end socket of the adapter tube.

[0010] Optionally, a pressing cylinder is fixed to the side of the mounting block, the button is placed in the pressing cylinder, and a return spring is connected between the button and the inner wall of the pressing cylinder.

[0011] Optionally, one end of the button is inserted into the movable cavity and movably connected to the end of the tilting rod.

[0012] Optionally, the return spring elastically abuts the button toward the outside of the mounting block, and the button drives the positioning column to extend toward the middle of the butt joint tube through the tilting rod.

[0013] Optionally, the middle portion of the tilting rod is rotatably mounted in the movable cavity.

[0014] Optionally, both ends of the tilting rod are provided with limiting through grooves, and the end of the button and the end of the positioning column are respectively placed in the limiting through grooves at both ends of the tilting rod.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the adapter tube being plugged into and matched with the butt tube through the plug-in tube, the adapter tube can be independently threaded and fixed to the end of the pressure gauge, so that the pressure gauge can be directly plugged and installed on the butt tube during installation, and can be disassembled and assembled without screwing. During subsequent disassembly and assembly operations such as maintenance, it is only necessary to plug and unplug the adapter tube and the butt tube. This can solve the problem that the existing pressure gauge adapter using a threaded installation method is prone to later rust or thread slippage, which makes it inconvenient for normal use.

[0017] At the same time, thanks to the cooperation of the butt joint tube, the mounting block, the button, the tilting rod and the positioning column, the button can be pressed to drive the positioning column to retract into the movable cavity in the mounting block through the tilting rod, thereby releasing the plug-in cooperation between the positioning column and the positioning hole on the plug-in tube, and then facilitating the rapid disassembly and assembly control of the plug-in of the transfer tube and the butt joint tube, which is simple to operate and easy to use.

In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0028] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0029] It is to be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers.

[0030] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings.

[0031] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a rotation-free installation adapter for a pressure gauge, including an adapter tube 2 for threadedly fixing the lower end of the pressure gauge 1, and a threaded portion 201 is constructed in the top end socket of the adapter tube 2, so that the pressure gauge 1 can be fixed to the adapter tube 2 by screwing, forming an integrated structure. In specific implementation, welding and other methods can also be used for fixing, mainly to form the pressure gauge 1 and the adapter tube 2 into a whole, and there is no need to disassemble and assemble at a later time. Therefore, even if rust occurs here, it will not have any effect, and since it will not be disassembled and assembled, it is difficult to have the problem of thread slippage.

[0032] Cooperate Figure 3 and Figure 4 As shown, the lower end of the adapter tube 2 is plugged into and matched with a docking tube 3, and a vertical plug-in tube 202 is fixed at the lower end of the adapter tube 2. A sealing ring 203 is arranged around the lower end of the plug-in tube 202. Positioning holes 204 are symmetrically provided on both sides of the adapter tube 2, and the docking tube 3 is plugged into and matched with the plug-in tube 202. A mounting block 4 is fixed around the middle of the docking tube 3, and a button 5 is elastically installed on the outer side of the mounting block 4. An active cavity 6 is provided in the mounting block 4, and a tilting rod 7 is rotatably installed in the middle of the active cavity 6. One end of the tilting rod 7 is movably connected to the button 5, and the other end of the tilting rod 7 is movably connected to a positioning column 8. The positioning column 8 horizontally penetrates into the middle part of the docking tube 3 and is plugged into and matched with the positioning hole 204. Therefore, when the plug-in tube 202 is inserted into the docking tube 3, the adapter tube 2 and the docking tube 3 can be stably plugged and fixed by plugging the positioning column 8 into the positioning hole 204.

[0033] A pressing cylinder 401 is fixed to the side of the mounting block 4, the button 5 is placed in the pressing cylinder 401, a return spring 501 is connected between the button 5 and the inner wall of the pressing cylinder 401, and one end of the button 5 is inserted into the movable cavity 6 and movably connected to the end of the tilting rod 7. The return spring 501 elastically abuts the button 5 in the direction outside the mounting block 4, and the button 5 drives the positioning column 8 to extend toward the middle of the butt tube 3 through the tilting rod 7.

[0034] In specific implementation, in this embodiment, the middle part of the tilting rod 7 is rotatably installed in the movable cavity 6, both ends of the tilting rod 7 are provided with limiting grooves, and the end of the button 5 and the end of the positioning column 8 are respectively placed in the limiting grooves at both ends of the tilting rod 7.

[0035] The utility model provides a working principle. The rotation-free installation adapter for a pressure gauge can, when in use, fix the lower end of the pressure gauge 1 to the top of the adapter tube 2 by means of threads, so that the pressure gauge 1 can be disassembled and assembled by plugging into the docking tube 3 through the adapter tube 2, and there is no need to separate the pressure gauge 1 and the adapter tube 2 during later disassembly and assembly, which can effectively avoid problems such as thread corrosion and thread slippage.

[0036] At the same time, for the plug-in cooperation between the adapter tube 2 and the docking tube 3, the button 5 can be pressed to drive the positioning column 8 to retract into the movable cavity 6 in the mounting block 4 through the tilting rod 7, thereby releasing the plug-in cooperation between the positioning column 8 and the positioning hole 204 on the plug-in tube 202, and then the plug-in of the adapter tube 2 and the docking tube 3 can be quickly disassembled and controlled, which is simple to operate and easy to use.

[0037] To sum up, the device can be disassembled and assembled without screwing. During subsequent disassembly and assembly operations such as maintenance, it is only necessary to plug and unplug the adapter tube 2 and the docking tube 3. This can solve the problem that the existing pressure gauge adapter uses a threaded screw installation method, which is prone to later rust or thread slippage and is inconvenient for normal use, and has a good use effect.

[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
