Description

An anti-loosening sealing cap for a pressure vessel Technical Field

[0001] This utility model relates to the field of pressure vessel technology, and in particular to an anti-loosening sealing cover for a pressure vessel. Background Technology

[0002] Pressure vessels are sealed devices that hold gases or liquids and withstand a certain pressure. They play an important role in many sectors, including industry, civil use, military, and scientific research. To ensure the sealing of pressure vessels, personnel use sealing covers. In existing technologies, multiple bolts with screw holes or nuts are commonly used to stably connect the sealing cover to the pressure vessel. However, this bolt and screw hole fixing method has low fixing efficiency, and after the pressure vessel is pressurized, the screws or bolts are prone to loosening during the vibration of a vibrating table with variable frequency acceleration, causing the pressure vessel's seal to fail. In addition, after installation, the sealing gasket inside the sealing cover may not effectively fit the pressure vessel, thus reducing its sealing performance. In view of the above, this application proposes an anti-loosening sealing cover for pressure vessels. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-loosening sealing cap for pressure vessels.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pressure vessel anti-loosening sealing cover includes a sealing cover body fitted onto the pressure vessel tank;

[0006] The T-shaped rubber sealing block is movably fitted inside the sealing cover and the pressure vessel tank, and the sealing between the sealing cover and the pressure vessel tank is achieved by the T-shaped rubber sealing block.

[0007] Four clamps are fixedly connected to the outside of the pressure vessel tank in a ring with equal spacing;

[0008] Four locking mechanisms are each movably locked into their corresponding sleeves. The sealing cover is fitted onto the four locking mechanisms. The locking mechanisms and sleeves work together to vertically restrict the sealing cover, thereby fixing it in place.

[0009] Multiple elastic guiding mechanisms are fixedly connected to their respective locking mechanisms. The sealing cover is sleeved on the multiple elastic guiding mechanisms, and the elastic guiding mechanisms provide lateral guidance to their respective locking mechanisms.

[0010] A synchronous drive mechanism is hinged to multiple locking mechanisms. The top of the sealing cover has a groove, and the synchronous drive mechanism is installed in the groove. The top of the synchronous drive mechanism extends to the top of the sealing cover. The synchronous drive mechanism is used to drive the four locking mechanisms to move synchronously.

[0011] The compression adjustment mechanism is in active contact with the top of the T-shaped rubber sealing block, and the synchronous drive mechanism is sleeved on the compression adjustment mechanism. The compression adjustment mechanism is used to compress the T-shaped rubber sealing block.

[0012] Preferably, the locking mechanism includes a locking block that is movably locked in the sleeve. The locking block and the sleeve are horizontally locked to restrict the sealing cover. Two opposite locking blocks are fixedly connected to rectangular rods on opposite sides. The outer side of the sealing cover is provided with four rectangular grooves with open bottoms on the outer side. The rectangular rods are movably fitted into the corresponding rectangular grooves.

[0013] Preferably, the elastic guiding mechanism includes guide rods. Two opposing guide rods are fixedly connected to the sides of two opposing rectangular rods that are close to each other. The guide rods provide lateral guidance to the corresponding rectangular rods. Two guide grooves are formed on the inner walls of the sides of the two opposing rectangular rods that are close to each other. The guide rods are slidably sleeved in the corresponding guide grooves. A first spring in a tensile state is fixedly connected between the end of the guide rod away from the corresponding rectangular rod and the inner wall of the guide groove. The first spring in a tensile state exerts a continuous tension on the guide rod, thereby exerting a continuous tension on the rectangular rods and the locking block, improving the locking stability.

[0014] Preferably, the synchronous drive mechanism includes a pressing box disposed in the groove. Four extrusion rods are annularly hinged to the outer side of the pressing box. The bottom end of the extrusion rod is hinged to the side of the corresponding rectangular rod near the pressing box. The extrusion rod is used to extrude and drive the corresponding rectangular rod. Four positioning rods are fixedly connected to the bottom inner wall of the groove. The pressing box is slidably sleeved on the four positioning rods. The positioning rods provide vertical guidance for the pressing box. Four second springs are fixedly connected between the bottom of the pressing box and the bottom inner wall of the groove. The second springs are movably sleeved on the corresponding positioning rods. When the second spring is in a compressed state and the extrusion force is released, it is used to drive the pressing box to move and reset.

[0015] Preferably, the compression adjustment mechanism includes a compression plate that is in movable contact with the top of the T-shaped rubber sealing block. A screw is rotatably mounted on the top of the compression plate. An internal threaded sleeve is fixedly connected to the bottom inner wall of the groove. The top of the screw passes through the groove and the pressing box in sequence, extends to the top of the pressing box, and is fixedly connected to a U-shaped rod. The internal threaded sleeve is threaded onto the screw. The threaded connection allows the screw to move vertically while rotating.

[0016] Preferably, the inner walls of the two opposing rectangular grooves that are close to each other are provided with through holes that communicate with the inside of the grooves, and the extrusion rod is located in the corresponding through hole.

[0017] Preferably, a first through hole is provided on the top inner wall of the pressing box, and the screw is located in the first through hole and does not contact the inner wall of the first through hole.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] 1. Through the cooperation of the locking mechanism, the sleeve, the elastic guide mechanism and the synchronous drive mechanism, the sealing cover can be installed by simply pressing, which is convenient for personnel operation and improves installation efficiency. Moreover, the lateral locking and the continuous pulling force of the first spring can effectively reduce the loosening of the sealing cover due to vibration, thus achieving an effective anti-loosening effect.

[0020] 2. By setting up the compression adjustment mechanism, the T-shaped rubber sealing block can be compressed after the sealing cover is installed, so that the outer side of the T-shaped rubber sealing block can effectively fit with the inner wall of the pressure vessel tank, which can effectively reduce the situation of reduced sealing performance due to ineffective fit.

[0021] This utility model, through a series of structural designs, enables the sealing cover to be quickly and stably installed and fixed by simple pressing, improving installation efficiency. At the same time, it can effectively reduce the loosening of the sealing cover due to vibration, achieving an effective anti-loosening effect. Furthermore, after the sealing cover is fixed, the T-shaped rubber sealing block can be squeezed, so that its outer side can effectively fit with the inner wall of the pressure vessel, improving sealing stability.

[0031] The locking mechanism includes a locking block 6 that is movably locked in the sleeve 5. The locking block 6 and the sleeve 5 are horizontally locked to restrict the sealing cover 1. Two opposite locking blocks 6 are fixedly connected to rectangular rods 4 on the side away from each other. The outer side of the sealing cover 1 is provided with four rectangular grooves 103 with open bottoms in a ring shape.

The guide rods 8 are slidably sleeved in the corresponding guide grooves 7. A limit groove is opened at the top of the guide rods 8. A limit block is fixedly connected to the inner wall of the top of the guide groove 7. The limit block is slidably connected to the corresponding limit groove.

A first spring 9 in a tensile state is fixedly connected between the end of the guide rod 8 away from the corresponding rectangular rod 4 and the inner wall of the guide groove 7. The first spring 9 in a tensile state exerts a continuous tension on the guide rod 8, thereby exerting a continuous tension on the rectangular rods 4 and the locking block 6, improving the locking stability.

[0034] The synchronous drive mechanism 2 has a groove 101 on the top of the sealing cover 1, and the synchronous drive mechanism 2 is installed in the groove 101. The top of the synchronous drive mechanism 2 extends to the top of the sealing cover 1.

[0035] The synchronous drive mechanism 2 includes a pressing box 201 disposed within a groove 101. Four pressing rods 204 are annularly hinged to the outer side of the pressing box 201. The bottom end of each pressing rod 204 is hinged to the side of a corresponding rectangular rod 4 near the pressing box 201. Two opposing rectangular grooves 103 each have a through hole 104 on their inner wall on the side closest to each other, communicating with the interior of the groove 101. The pressing rods 204 are located within the corresponding through holes 104, which allow the pressing rods 204 to pass through. The pressing rods 204 are used to press and drive the corresponding rectangular rods 4. The bottom of the groove 101... Four positioning rods 202 are fixedly connected to the inner wall. The pressing box 201 is slidably sleeved on the four positioning rods 202. The top of the pressing box 201 has four positioning holes.

The positioning rods 202 play a vertical guiding role for the pressing box 201. Four second springs 203 are fixedly connected between the bottom of the pressing box 201 and the bottom inner wall of the groove 101. The second springs 203 are movably sleeved on the corresponding positioning rods 202. When the second springs 203 are in the compressed state and the squeezing force is released, they are used to drive the pressing box 201 to move and reset.

[0036] The compression adjustment mechanism 3 is in active contact with the top of the T-shaped rubber sealing block 102. The synchronous drive mechanism 2 is sleeved on the compression adjustment mechanism 3. The compression adjustment mechanism 3 is used to compress the T-shaped rubber sealing block 102.

[0037] The compression adjustment mechanism 3 includes a compression plate 303 that is in movable contact with the top of the T-shaped rubber sealing block 102. A screw 302 is rotatably mounted on the top of the compression plate 303. A bearing is fixedly connected to the top of the compression plate 303, and the inner side of the inner ring of the bearing is fixedly connected to the outer side of the screw 302. The bearing serves to allow the screw 302 to rotate. A second through hole communicating with the inside of the groove 101 is opened on the top inner wall of the sealing cover 1. The bearing is located in the second through hole and does not contact the inner wall of the second through hole. An internal threaded sleeve 304 is fixedly connected to the bottom inner wall of the groove 101. The top of the screw 302 passes through the groove 101 and the pressing box 201 in sequence, extends to the top of the pressing box 201, and is fixedly connected to a U-shaped rod 301. The internal threaded sleeve 304 is threaded onto the screw 302. The threaded connection allows the screw 302 to rotate and move vertically simultaneously. A first through hole is provided on the top inner wall of the pressing box 201. The screw 302 is located in the first through hole and does not contact the inner wall of the first through hole. Through a series of structural designs, this utility model can quickly and stably install and fix the sealing cover 1 by simple pressing, improving installation efficiency. At the same time, it can effectively reduce the loosening of the sealing cover 1 caused by vibration, achieving an effective anti-loosening effect. Furthermore, after fixing the sealing cover 1, the T-shaped rubber sealing block 102 can be squeezed, so that its outer side can effectively fit against the inner wall of the pressure vessel tank 100, improving sealing stability.

[0038] Working principle: During use, before the sealing cover 1 is installed on the pressure vessel tank 100, the installation process begins by first fitting the T-shaped rubber sealing block 102 into the pressure vessel tank 100. Then, the pressing box 201 is pressed down, causing it to slide downwards on the four positioning rods 202 and compress the second spring 203. Simultaneously, the pressing box 201 compresses the four pressing rods 204, causing them to rotate. The pressing rods 204 compress the corresponding rectangular rods 4, which in turn move the corresponding guide rods 8 within the guide grooves 7, stretching the first spring 9. The four rectangular rods 4 expand outwards simultaneously, moving their corresponding locking blocks 6 into the rectangular grooves 103. Next, the sealing cover 1 is fitted onto the pressure vessel tank 100, causing the T-shaped rubber sealing block 102 to fit inside. When the locking block 6 is laterally aligned with the corresponding locking sleeve 5, the pressing pressure on the pressing box 201 is released. At this point, the second spring 203, which is in a compressed state... The elastic force of spring 203 drives the pressing box 201 to move upward. The pressing box 201 pulls the four squeezing rods 204 upward, causing the four squeezing rods 204 to rotate and reset, releasing the squeezing force on the corresponding rectangular rods 4. At this time, the elastic force of the first spring 9 in the stretched state drives the rectangular rod 4 to move laterally and reset through the corresponding guide rod 8. The rectangular rod 4 drives the corresponding locking block 6 to be locked into the sleeve 5. The locking block 6 and the corresponding sleeve 5 are locked together, thereby realizing the vertical restriction of the sealing cover 1, and thus completing the installation of the sealing cover 1. The sealing cover 1 is installed by simply pressing, which is convenient for personnel operation and improves installation efficiency. Since the sealing cover 1 is fixed by lateral locking, in conjunction with the continuous pulling force of the first spring 9 in the stretched state on the rectangular rod 4, the locking block 6 will not move out of the sleeve 5 under vibration, thus effectively reducing the loosening of the sealing cover 1 caused by vibration and achieving an effective anti-loosening effect.

[0039] After the sealing cover 1 is fixed, the boom 301 is rotated forward. The boom 301 drives the screw 302 to rotate in the inner thread sleeve 304 and move downward. The screw 302 drives the extrusion plate 303 to press the T-shaped rubber sealing block 102 downward. Under the extrusion force, the T-shaped rubber sealing block 102 is squeezed tightly against the end of the pressure vessel tank 100, and the part inserted into its inner side is also sealed, which improves the sealing stability and can effectively reduce the situation of reduced sealing performance due to ineffective fit.

[0040] When it is necessary to release the sealing cover 1, press the pressing box 201 down again to make the multiple locking blocks 6 move laterally and move out of the corresponding locking sleeve 5, thereby releasing the sealing cover 1.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
