DETAILED DESCRIPTION

[0019] To make the technical means, creative features, objectives and effects of the utility model easy to understand

[0020] Understand, the utility model is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a stainless steel seismic-resistant joint for industrial instruments that is easy to install, including an industrial pressure gauge 1, the inner ring of the bottom input end of the industrial pressure gauge 1 is provided with a threaded inner wall, the bottom end of the industrial pressure gauge 1 is provided with a seismic-resistant joint body 2, the bottom end of the seismic-resistant joint body 2 is provided with a stainless steel buffer tube 3, the stainless steel buffer tube 3 is a fitting for connecting the pressure gauge and the equipment or pipeline measured by the pressure gauge, and is used to buffer the instantaneous impact of the measured medium on the spring tube of the pressure gauge, and at the same time can reduce the temperature of the measured medium, and is a device for protecting the pressure gauge, the seismic-resistant joint body 2 includes a joint tube body 21, and the top of the joint tube body 21 is fixedly connected with a quick-install mechanism 22, a pentagonal outer nut 23 is fixedly installed on the outer wall of the joint body 21, and an access ring 24 is fixedly installed on the bottom end of the pentagonal outer nut 23. The quick-install mechanism 22 includes a threaded quick-install joint 222, which is threadedly connected to the inner ring of the bottom input end of the industrial pressure gauge 1, and a limit plate 221 is fixedly installed at the bottom of the outer wall of the threaded quick-install joint 222. The bottom end of the threaded quick-install joint 222 is fixedly connected to the top of the joint body 21, and an annular groove 223 is opened on the top of the threaded quick-install joint 222. An embedded tightening rubber ring 224 is fixedly installed on the outer wall of the annular groove 223, and a conical sealing rubber ring 225 is fixedly installed on the top of the limit plate 221;

[0022] When it is necessary to connect the integral seismic-resistant joint body 2 with the input end of the industrial pressure gauge 1, the joint body 21 is connected to the inner circle of the input end of the industrial pressure gauge 1 by means of the threaded quick-release joint 222, so as to be quickly installed. After the threaded quick-release joint 222 is threadedly installed, the pentagonal outer nut 23 on the outer wall of the joint body 21 can be rotated by a wrench, so that the joint body 21 is further fixed until it stops rotating after it abuts against the input end of the industrial pressure gauge 1 against the limit plate 221. At the same time, the embedded tightening rubber ring 224 on the outer wall of the annular groove 223 at the top of the threaded quick-release joint 222 and the conical sealing rubber ring 225 at the top of the limit plate 221 are used to ensure the sealing between the joint body 21 and the industrial pressure gauge 1 after quick fixation, and at the same time, the elasticity of the conical sealing rubber ring 225 is used to improve the seismic resistance of the joint body 21.

[0023] like Figure 4 As shown, the inner ring of the access ring 24 is provided with a threaded wall 241, and the top output end of the stainless steel buffer tube 3 is threadedly connected to the access ring 24 by means of the threaded wall 241. A plurality of spring grooves 211 are provided in an annular array at the bottom end of the joint body 21, and a compression mechanism 212 is provided inside each of the plurality of spring grooves 211. A compression ring plate 213 is provided at the bottom end of each of the plurality of compression mechanisms 212, and a compression sealing ring 214 is fixedly installed at the bottom of the compression ring plate 213. The side surface of the compression sealing ring 214 overlaps with the upper part of the inner ring of the access ring 24, and a fitting ring 215 is fixedly installed at one side of the bottom of the compression sealing ring 214 near the center of the circle;

[0024] The top output end of the stainless steel buffer tube 3 is rotationally threadedly connected to the threaded wall 241 of the inner ring of the access ring 24 until the output end of the stainless steel buffer tube 3 moves upward and pushes up the compression sealing ring 214. At this time, the fitting ring 215 will be stuck in the inner ring of the output end of the stainless steel buffer tube 3 to improve the sealing performance. At the same time, the compression sealing ring 214 uses the compression ring plate 213 fixed on the top to squeeze the multiple compression mechanisms 212 in the multiple spring grooves 211.

[0025] like Figure 5 As shown, several compression mechanisms 212 include fixed cylinders 2121 and compression springs 2123. Several compression springs 2123 are respectively located on the outside of several fixed cylinders 2121. Several fixed cylinders 2121 are respectively fixedly connected to the center of the top of the inner cavity of several spring grooves 211. The tops of several compression springs 2123 are respectively fixedly connected to the top of the inner cavity of several spring grooves 211. The inner cavities of several fixed cylinders 2121 are slidably installed with telescopic rods 2122 that penetrate to the bottom of the fixed cylinders 2121. The bottom ends of several telescopic rods 2122 and compression springs 2123 are fixedly connected to the top of the compression ring plate 213.

[0026] After the output end of the stainless steel buffer tube 3 is connected to the access ring 24, when the compression ring plate 213 is squeezed, the compression spring 2123 included in the compression mechanism 212 will be compressed, so that the compression spring 2123 moves into the spring groove 211. At the same time, the sliding and extension of the telescopic rod 2122 and the fixed tube 2121 are utilized to maintain stability until the output end of the stainless steel buffer tube 3 pushes the compression ring plate 213 upward to the bottom of the joint body 21. The elasticity of several compression springs 2123 is utilized to improve the sealing performance between the compression sealing ring 214 and the output end of the stainless steel buffer tube 3.

[0027] The following is a detailed description of the working principle of this easy-to-install stainless steel seismic-resistant joint for industrial instruments.

[0028] like Figure 1-5 As shown, when the integral seismic-resistant joint body 2 needs to be connected to the input end of the industrial pressure gauge 1, the joint body 21 is connected to the thread of the inner ring of the input end of the industrial pressure gauge 1 by using the threaded quick-release joint 222, so as to be quickly installed. After the threaded quick-release joint 222 is threadedly installed, the pentagonal outer nut 23 on the outer wall of the joint body 21 can be rotated by a wrench to further fix the joint body 21 until it stops rotating after it abuts against the input end of the industrial pressure gauge 1 against the limit plate 221. At the same time, the embedded tightening rubber ring 224 on the outer wall of the annular groove 223 at the top of the threaded quick-release joint 222 and the conical sealing rubber ring 225 at the top of the limit plate 221 are used to ensure the sealing between the joint body 21 and the industrial pressure gauge 1 after quick fixation. Then, the top output end of the stainless steel buffer tube 3 can be connected to the inner ring of the access ring 24. The threaded wall 241 is rotated and threadedly connected until the output end of the stainless steel buffer tube 3 moves upward and pushes up the compression sealing ring 214. At this time, the fitting ring 215 will be stuck in the inner ring of the output end of the stainless steel buffer tube 3 to improve the sealing performance. At the same time, the compression sealing ring 214 uses the compression ring plate 213 fixed on the top to squeeze the multiple compression mechanisms 212 in the multiple spring grooves 211. During the squeezing, the compression spring 2123 included in the compression mechanism 212 is compressed, so that the compression spring 2123 moves into the spring groove 211. At the same time, the sliding and extension of the telescopic rod 2122 and the fixed cylinder 2121 are used to maintain stability until the output end of the stainless steel buffer tube 3 pushes the compression ring plate 213 upward to the bottom of the joint body 21, and the elasticity of the multiple compression springs 2123 is used to improve the sealing performance of the compression sealing ring 214 and the output end of the stainless steel buffer tube 3.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
