Description

Technical Field

[0001] The utility model relates to the technical field related to pressure gauges, and in particular to an installation structure of a portable pressure gauge. Background Art

[0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is used to measure and indicate the size of the pressure inside the pressure product. When using the pressure gauge, the user needs to install the pressure gauge. Most of the pressure gauges on the current market are installed by users by twisting the threads. If the tightening force is large, it will be difficult to remove. Different threads require different mounting parts for disassembly and fixing, which is too time-consuming. In addition, corresponding installation tools are required for different pressure gauges, which makes the overall carrying inconvenient. At the same time, the installation process of the pressure gauge will not be fast enough, which is more troublesome. Not only is it not portable, but the installation efficiency is also low.

[0003] Therefore, a portable pressure gauge installation structure is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a portable pressure gauge installation structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A portable pressure gauge installation structure includes a pressure gauge body, a cylindrical detection end is fixedly provided at the lower end of the pressure gauge body, a fixed sleeve is fixedly sleeved on the detection end, an external thread is provided on the fixed sleeve, an upper clamp and a plurality of lower clamps are sleeved on the fixed sleeve, the upper clamp is arranged in a truncated cone shape, the upper clamp is threadedly sleeved on the fixed sleeve through a threaded structure, the lower clamp is arranged in a straight claw structure, a plurality of accommodating grooves matching the lower clamp are arranged around the lower end of the fixed sleeve, the lower clamp is placed in the accommodating groove and the lower end of the lower clamp is rotatably connected to the lower end of the fixed sleeve.

[0007] Preferably, a thick rubber sealing layer is fixedly provided on the lower end surface of the upper clamping member.

[0008] Preferably, a sealing ring is fixedly provided on the upper end of the upper clamp and a sealing sleeve of the sealing ring is provided on the fixed sleeve.

[0009] Preferably, a rubber contact head is fixedly provided on each of the plurality of lower clamping members.

[0010] Preferably, an elastic limiting member is provided between the plurality of lower clamping members and the fixed sleeve.

[0011] Preferably, a section of the outer wall of the fixing sleeve corresponding to the sealing ring is configured to be smooth.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the structure of the device is integral, so that the integral pressure gauge is convenient to carry. During installation, the fixing sleeve and the detection end are simultaneously inserted into the mounting hole. At the same time, a plurality of lower clamps are arranged at the lower end of the fixing sleeve. When the fixing sleeve is inserted into the mounting hole, the plurality of lower clamps pop out to play a limiting role. At the same time, an upper clamp threaded on the fixing sleeve is arranged. By rotating the upper clamp and cooperating with the plurality of lower clamps, the integral pressure gauge can be fixed on the mounting hole. At the same time, the rotation of the upper clamp can further tighten the pressure gauge. A thick rubber sealing layer is arranged on the upper clamp to achieve a sealing effect. The overall device is easy to carry and easy to install, and has high applicability and high sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 A portable pressure gauge installation structure shown includes:

[0020] The pressure gauge body 1 adopts the existing technology, and a cylindrical detection end 2 is fixedly arranged at the lower end of the pressure gauge body 1. In order to facilitate the installation of the overall pressure gauge, a fixed sleeve 3 is fixedly sleeved on the detection end 2, and an external thread is arranged on the fixed sleeve 3. An upper clamp 4 and a plurality of lower clamps 5 are sleeved on the fixed sleeve 3. The upper clamp 4 is arranged in a truncated cone shape, and the upper clamp 4 is threadedly sleeved on the fixed sleeve 3 through a threaded structure. The upper clamp 4 can be realized by rotating the upper clamp 4. At the same time, the lower clamp 5 is arranged in a straight claw structure, and a plurality of accommodating grooves matching the lower clamp 5 are arranged around the lower end of the fixed sleeve 3. The lower clamp 5 is placed in the accommodating groove and the lower end of the lower clamp 5 is rotatably connected to the lower end of the fixed sleeve 3. When the fixed sleeve 3 is inserted into the mounting hole, the plurality of lower clamps 5 rotate, which can play a limiting role. With the movement of the upper clamp 4 and the tightening effect, the installation of the overall pressure gauge can be realized.

[0021] When the installation and fixing is performed, in order to ensure the installation stability and sealing, a thick rubber sealing layer 6 is fixedly provided on the lower end surface of the upper clamp 4 .

[0022] Because the upper clamp 4 and the fixed sleeve 3 move relative to each other, in order to ensure the sealing, a sealing ring 7 is fixedly provided on the upper end of the upper clamp 4 and the sealing ring 7 is sealed on the fixed sleeve 3. In order to ensure the effect of the sealing ring 7, a section of the outer wall of the fixed sleeve 3 corresponding to the sealing ring 7 is set to be smooth, and at the same time, the thread structure of the lower thread of the fixed sleeve 3 and the partial thread between the upper clamp 4 is not affected.

[0023] In some embodiments, in order to ensure the stability of the pressing and avoid damage caused by rigid contact, a rubber contact head 8 is fixedly provided on each of the lower clamps 5 .

[0024] At the same time, in order to facilitate the lower clamping member 2 to be expanded to achieve the limiting effect after being inserted into the fixed sleeve 3, an elastic limiting member 9 is arranged between the plurality of lower clamping members 5 and the fixed sleeve 3. When carrying, the plurality of lower clamping members 5 can be limited by the upper clamping member 4.
