Description

Technical Field

[0001] This utility model belongs to the field of pressure transmitter technology, and in particular relates to a reinforced fastening structure for a pressure transmitter flange. Background Technology

[0002] According to the published patent CN211423082U, a threaded connection fixing device for a single-flange pressure transmitter consists of two semi-circular groove square blocks and four hexagonal head screws. The two semi-circular groove square blocks are symmetrically structured and are square plate structures with a groove in the middle. The inner sidewall of the groove has a toothed structure, which can more effectively prevent silicone oil leakage caused by loose threads, ensure the vacuum degree in the transmitter cavity, and ensure the long-term stable operation of the pressure transmitter. However, it still has the following shortcomings: While the aforementioned equipment allows for the connection and installation of pressure transmitters and connecting pipes, the installation method is rather cumbersome, requiring external tools for assistance, which is inconvenient and prolongs the installation time. Therefore, we propose an enhanced fastening structure for the pressure transmitter flange. Summary of the Invention

[0003] The purpose of this utility model is to provide a reinforced fastening structure for a pressure transmitter flange. Through the installation mechanism and the reinforcement mechanism, it solves the problem that although the pressure transmitter can be connected and installed to the connecting pipe, the installation method is relatively cumbersome, requires external tools for assistance, which is inconvenient and prolongs the installation time of the device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a reinforced fastening structure for a pressure transmitter flange, including a pressure transmitter, a connecting pipe slidably connected to the bottom outer wall of the pressure transmitter, and an installation mechanism provided on the outer wall of the pressure transmitter. The mounting mechanism includes several fixing blocks. The inner wall of the pressure transmitter near one of the fixing blocks has several slots. Each fixing block has a threaded rod rotatably connected to its inner wall. A connecting rod is threaded to the outer wall of each threaded rod. Several limiting shafts are rotatably connected to the inner wall of each connecting rod. A locking block is rotatably connected to the outer wall of each limiting shaft. Several limiting rods are fixedly connected to the outer wall of the connecting pipe near one of the locking blocks. An arc-shaped groove is formed on the inner wall of each locking block near one of the limiting rods. A sealing gasket is fixedly connected to the inner wall of the connecting pipe. A throttle is fixedly connected to the bottom outer wall of each threaded rod. A reinforcement mechanism is provided on the outer wall of the pressure transmitter.

[0005] Furthermore, the outer walls of several of the fixing blocks are fixedly connected to the inner wall of the connecting pipe, and the inner wall of the arc-shaped groove is slidably connected to the outer wall of the limiting rod.

[0006] Furthermore, the reinforcement mechanism includes several fixing blocks 2, and the outer walls of the several fixing blocks 2 are fixedly connected to the outer wall of the connecting pipe.

[0007] Furthermore, several fixed blocks three are fixedly connected to the outer wall of the pressure transmitter near the fixed block two, and the inner walls of the several fixed blocks three are rotatably connected with insert rods.

[0008] Furthermore, each of the inner walls of several of the fixed blocks 2 is fixedly connected with a plug sleeve, and the inner wall of the plug sleeve is provided with a slot.

[0009] Furthermore, a fixing frame is fixedly connected to the bottom outer wall of each of the several insertion rod sleeves, and a several insertion rods are slidably connected to the inner wall of the fixing frame.

[0010] Furthermore, a limiting block is fixedly connected to the outer wall of each of the several insertion rods 2, and a spring is fixedly connected to the outer wall of each of the limiting blocks near the end of the insertion rod 2, and the outer wall of the spring is fixedly connected to the outer wall of the insertion rod 2.

[0011] Furthermore, the inner wall of the insertion rod sleeve near the second insertion rod has several insertion holes, the inner wall of the insertion holes is inserted into the outer wall of the second insertion rod, and the top outer wall of several insertion rods is fixedly connected with a throttle handle.

[0012] This utility model has the following beneficial effects: 1. This utility model features an arc-shaped groove within the locking block. When the equipment is needed, the second insertion rod is pulled outward to move the limiting block and compress the spring. After the second insertion rod is completely pulled out of the insertion hole, the second throttle is rotated. The rotation of the second throttle causes the insertion rod to rotate within the third fixing block. When the insertion hole rotates to the appropriate angle, the second insertion rod can be released. Since the second insertion rod cannot be aligned with the insertion hole, it will not be locked inside the insertion hole. This facilitates the installation of the pressure transmitter on the connecting pipe, allowing users to quickly install the pressure transmitter on the connecting pipe manually without the need for additional tools such as wrenches or screwdrivers. The entire installation process has fewer steps and is less time-consuming, significantly reducing the operational threshold and installation difficulty.

[0013] 2. This utility model incorporates a limiting block on the second insert rod. During equipment use, the rotation of the threaded rod drives the connecting rod to gradually move upward. As the connecting rod moves upward, it pushes the locking block to gradually rise through the limiting shaft. Because the locking block has an arc-shaped groove that slides on the limiting rod, the locking block moves along the trajectory of the arc-shaped groove. This allows the locking block to rotate around the limiting shaft and gradually retract during the lifting process. This reinforces the connection after the pressure transmitter is installed in the connecting pipe, effectively improving the overall connection stability of the device. It prevents the connection from loosening or falling off due to vibration and pressure fluctuations during long-term use, thereby preventing material leakage from the gaps in the pipe and ensuring operational safety and stable material transport.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 As shown, this utility model is a reinforced fastening structure for a pressure transmitter flange, including a pressure transmitter 1, a connecting pipe 101 slidably connected to the bottom outer wall of the pressure transmitter 1, and an installation mechanism 2 provided on the outer wall of the pressure transmitter 1. The mounting mechanism 2 includes several fixing blocks 201. These fixing blocks 201 limit the position of the threaded rod 202, preventing it from falling off and allowing it to rotate within the fixing blocks 201. The pressure transmitter 1 has several slots 209 on its inner wall near one end of the fixing blocks 201. Each fixing block 201 has a threaded rod 202 rotatably connected to its inner wall. A connecting rod 203 is threadedly connected to the outer wall of the threaded rod 202. Several limiting shafts 204 are rotatably connected to the inner wall of the connecting rod 203. These limiting shafts 204 limit the position of the locking block 205. When the limiting shaft 204 moves, it drives the locking block 205 to move, ensuring that the locking block 205 can only rotate around the limiting shaft 204. Each wall is rotatably connected with a locking block 205. Several limiting rods 207 are fixedly connected to the outer wall of the connecting pipe 101 near the locking block 205. Each inner wall of the locking block 205 near the limiting rod 207 is provided with an arc-shaped groove 206. The movement of the locking block 205 can be limited by the arc-shaped groove 206. Since the arc-shaped groove 206 slides on the limiting rod 207, the movement trajectory of the locking block 205 will change with the arc-shaped groove 206. A sealing gasket 208 is fixedly connected to the inner wall of the connecting pipe 101. A handle 210 is fixedly connected to the bottom outer wall of several threaded rods 202. A reinforcing mechanism 3 is provided on the outer wall of the pressure transmitter 1. The sealing gasket 208 can seal the connection between the pressure transmitter 1 and the connecting pipe 101 to prevent material leakage.

[0020] The outer walls of several fixing blocks 201 are fixedly connected to the inner wall of the connecting pipe 101, and the inner wall of the arc-shaped groove 206 is slidably connected to the outer wall of the limiting rod 207. The reinforcing mechanism 3 includes several fixing blocks 301, the outer walls of which are fixedly connected to the outer wall of the connecting pipe 101. The fixing blocks 301 can fix the position of the insert sleeve 303, preventing the insert sleeve 303 from loosening. Since the fixing blocks 301 are evenly distributed around the connecting pipe 101, they can... The pressure transmitter 1 experiences more uniform pressure. Several fixed blocks 311 are fixedly connected to the outer wall of one end of the pressure transmitter 1 near the fixed block 2 301. Insert rods 302 are rotatably connected to the inner walls of the several fixed blocks 311. Insert rod sleeves 303 are fixedly connected to the inner walls of the several fixed blocks 2 301. The inner wall of the insert rod sleeve 303 has a slot 304. When the user inserts the insert rod 302 into the deepest part of the slot 304 and rotates it to a suitable angle, the insert rod 302 can be locked in the slot 304.

[0021] A fixing frame 305 is fixedly connected to the bottom outer wall of several insertion rod sleeves 303. Several insertion rods 306 are slidably connected to the inner wall of the fixing frame 305. Limiting blocks 309 are fixedly connected to the outer wall of each insertion rod 306. The limiting blocks 309 can fix the position of the spring 307 and prevent the user from pulling the insertion rod 306 completely out of the fixing frame 305. A spring 307 is fixedly connected to the outer wall of each limiting block 309 near the insertion rod 306. The outer wall of the spring 307 is fixed to the outer wall of the insertion rod 306. The connection is as follows: the inner wall of the insertion rod sleeve 303 near the insertion rod 306 has several insertion holes 308. The spring 307 can use its own elastic force to squeeze the limiting block 309 so that the insertion rod 306 is always inserted into the insertion hole 308, preventing the insertion rod 306 from sliding out on its own. The inner wall of the insertion hole 308 is inserted into the outer wall of the insertion rod 306. The top outer wall of several insertion rods 302 is fixedly connected to the handle 310. When the user pulls out the insertion rod 306 and rotates the handle 310 to a suitable angle, the insertion rod 302 can be pulled out from the slot 304.

[0022] One specific application of this embodiment is: When the equipment is needed, the pressure transmitter 1 can be fixed to the connecting pipe 101 by using the locking block 205. The insertion rod 302 and the insertion rod sleeve 303 together reinforce the connection between the pressure transmitter 1 and the connecting pipe 101 to prevent material leakage. If the pressure transmitter 1 needs to be removed from the connecting pipe 101 for maintenance, first pull the insertion rod 306 outward to move the limit block 309 and compress the spring 307. After the insertion rod 306 is completely pulled out of the insertion hole 308, turn the handle 310. The turn of the handle 310 will cause the insertion rod 302 to rotate within the fixing block 311. When the insertion hole 308 is rotated to the appropriate angle, the insertion rod 306 can be released. At this time, because the insertion rod 306 cannot be aligned with the insertion hole 308, the insertion rod 306 will not be locked in the insertion hole 308, thus preventing the insertion rod from being locked in place. After relocking 302, once all the inserts 302 are released, the threaded rod 202 can be rotated. The rotation of the threaded rod 202 drives the connecting rod 203 to gradually move upwards. As the connecting rod 203 moves upwards, it pushes the locking block 205 to gradually rise via the limiting shaft 204. Because the locking block 205 has an arc-shaped groove 206 that slides on the limiting rod 207, the locking block 205 follows the trajectory of the arc-shaped groove 206 during its movement. The movement allows the locking block 205 to rotate around the limiting shaft 204 and gradually retract during the lifting process. When the locking block 205 no longer locks the pressure transmitter 1, the pressure transmitter 1 can be directly removed from the connecting pipe 101. After the pressure transmitter 1 is maintained, it is reinstalled on the connecting pipe 101 and the handles 210 and 310 are rotated in the opposite direction to reset the locking block 205 and the insertion rod 302, thus completing the re-fixing and installation of the pressure transmitter 1.
