Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, and in particular to a multi-cylinder locking structure. Background Technology

[0002] In industrial filtration systems, cylinders are widely used in applications requiring linear reciprocating motion or a certain clamping force due to their advantages such as simple structure, rapid action, easy automation control, relatively convenient maintenance, and low cost.

[0003] To improve the stability of filtration operation, the filter cartridge needs to be opened regularly for inspection and maintenance. In order to ensure that the filter is working properly, the filter needs to be opened regularly for cleaning. Due to the unique structure of the cylinder, people usually use the cylinder to drive the opening and closing of the cover, making it convenient for operators to access the inside of the equipment.

[0004] Because the inspection and cleaning of filters require maintenance personnel to open the filter cartridge and even enter the inside of the filter cartridge to perform the work, if the cylinder leaks air during the maintenance process, it is very likely that the cover plate will fall and cause a safety accident. In addition, if the pressure inside the filter is too high and the cylinder is not locked in time, the cover plate can be pushed open, which will seriously affect the normal operation of the filter and even cause a serious safety accident. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-cylinder locking structure that can improve safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-cylinder locking structure, including a filter cylinder, on which cylinders are uniformly fixedly installed, and a cylinder cover is fixedly installed on the output end of the cylinder. The cylinder includes a cylinder body, and a piston plate is vertically slidably installed inside the cylinder body. A connecting rod that is fixedly connected to the cylinder cover is fixedly installed on the top wall of the piston plate, and a locking assembly is provided on the piston plate.

[0007] The locking assembly includes a groove formed on the piston plate, a locking rod slidably installed in the groove, locking grooves that cooperate with the locking rod are evenly formed on the inner wall of the cylinder, a spring is installed between the locking rod and the groove, a solenoid valve is fixedly installed on the bottom wall of the cylinder, and an air pipe is connected to the solenoid valve, and a groove communicating with the groove is formed on the bottom wall of the piston plate.

[0008] Preferably, the piston plate is embedded with a coil electrically connected to the solenoid valve, and the locking rod is embedded with a magnet that cooperates with the coil.

[0009] Preferably, the cylinder block is provided with an exhaust groove.

[0010] Preferably, a pneumatic telescopic rod is fixedly installed on the cylinder body, and a sealing plate is fixedly installed on the output end of the pneumatic telescopic rod, and a connecting pipe communicating with the pneumatic telescopic rod is inserted into the slide groove.

[0011] Preferably, a connecting groove is provided between the two slides, and the two slides are connected through the connecting groove.

[0012] Preferably, an iron core that mates with the coil is fixedly mounted on the piston plate.

[0013] Preferably, the end of the locking rod away from the first spring is an inclined plane.

[0014] Preferably, the surface of the locking groove is a smooth mirror surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application, by setting a locking rod, allows air to be drawn from the slide groove through the groove in the space below the piston plate in the cylinder when the pressure inside the filter cartridge is too high and causes the cartridge cover to move upward. This causes the locking rod to be inserted into the locking groove, thereby fixing the piston plate. When the cylinder leaks air, the pressure inside the cylinder below the piston plate decreases. At this time, the spring extends and causes the locking rod to be inserted into the locking groove, thereby limiting the piston plate in time and fixing the cartridge cover. This effectively prevents the cartridge cover from falling or opening automatically, thus improving safety.

[0017] 2. This application, by setting a sealing plate, compresses the airflow in the slide groove and flows into the pneumatic telescopic rod through the connecting pipe as the two locking rods approach each other. This causes the output end of the pneumatic telescopic rod to gradually contract. During the contraction of the output end of the pneumatic telescopic rod, the sealing plate disengages from the exhaust groove. Then, as the piston plate moves upward, the airflow above the piston plate in the cylinder can flow normally to the outside through the air hole. When the locking rod is inserted into the locking groove, the slide groove draws air from the pneumatic telescopic rod through the connecting pipe. Then, the output end of the pneumatic telescopic rod extends and causes the sealing plate to block the air hole, thereby increasing the resistance to piston plate movement and further improving safety.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution:

[0029] A multi-cylinder locking structure includes a filter cartridge 1, on which cylinders 2 are uniformly fixedly installed. A cylinder cover 12 is fixedly installed on the output end of the cylinder 2. The cylinder 2 includes a cylinder body 201. A piston plate 202 is vertically slidably installed inside the cylinder body 201. A connecting rod 203 fixedly connected to the cylinder cover 12 is fixedly installed on the top wall of the piston plate 202. A locking assembly 3 is provided on the piston plate 202.

[0030] The locking assembly 3 includes a groove formed on the piston plate 202, a locking rod 301 slidably installed in the groove, and locking grooves 302 that cooperate with the locking rod 301 are evenly formed on the inner wall of the cylinder 201. A spring 303 is installed between the locking rod 301 and the groove. A solenoid valve 304 is fixedly installed on the bottom wall of the cylinder 201, and an air pipe 305 is connected to the solenoid valve 304. A groove 306 communicating with the groove is formed on the bottom wall of the piston plate 202.

[0031] The piston plate 202 is fitted with a coil 4 that is electrically connected to the solenoid valve 304, and the locking rod 301 is fitted with a magnet 5 that cooperates with the coil 4.

[0032] When the pressure inside the filter cartridge 1 becomes too high and causes the cartridge cover 12 to move upward, the cartridge cover 12 drives the piston plate 202 to move upward via the connecting rod 203. At this time, the pressure inside the cylinder 201 below the piston plate 202 decreases, and under the action of the pressure, the space inside the cylinder 201 below the piston plate 202 draws air from the slide groove through the groove 306. At this time, the spring 303 extends and drives the locking rod 301 to insert into the locking groove 302, thereby fixing the piston plate 202 and thus fixing the cartridge cover 12, effectively preventing the cartridge cover 12 from opening. When it is necessary to open the cartridge cover 12 for maintenance, the user can open the solenoid valve 304 and vent air into the cylinder 201 through the air pipe 305. Then, under the action of the airflow, the space inside the cylinder 201 below the piston plate 202... The pressure increases, and under the action of the pressure, the airflow flows through the groove 306 to the slide groove, thereby driving the locking rod 301 to compress the spring 303. During the process of the locking rod 301 compressing the spring 303, the locking rod 301 gradually disengages from the locking groove 302. Then, as the airflow flows into the cylinder 201, the piston plate 202 drives the cylinder cover 12 to move upward through the connecting rod 203, thereby opening the cylinder cover 12. When the cylinder 2 leaks air, the pressure in the cylinder 201 below the piston plate 202 decreases. At this time, the spring 303 extends and drives the locking rod 301 to insert into the locking groove 302, thereby limiting the piston plate 202 in time and fixing the cylinder cover 12, effectively preventing the cylinder cover 12 from falling and improving safety.

[0033] When the cylinder cover 12 needs to be closed, the user first controls the electromagnet to be energized. Then the electromagnet generates an electromagnetic field, and under the action of the electromagnetic field, the magnet 5 drives the locking rod 301 to disengage from the locking groove 302. Then the user can slowly discharge the airflow in the cylinder 201 through the air pipe 305 through the solenoid valve 304. At this time, the pressure in the cylinder 201 below the piston plate 202 gradually decreases. Then the piston plate 202 drives the cylinder cover 12 to slowly descend through the connecting rod 203, thereby achieving the purpose of closing the cylinder cover 12.

[0034] Specifically, such as Figure 2 , Figure 3 , Figure 4 As shown, the cylinder body 201 has an exhaust groove 6.

[0035] A pneumatic telescopic rod 7 is fixedly installed on the cylinder body 201, and a sealing plate 8 is fixedly installed on the output end of the pneumatic telescopic rod 7. A connecting pipe 9 connected to the pneumatic telescopic rod 7 is inserted into the slide groove.

[0036] A connecting groove 10 is provided between the two slides, and the two slides are connected through the connecting groove 10.

[0037] By adopting the above technical solution, during the process of the two locking rods 301 approaching each other, the airflow in the slide groove is compressed and flows into the pneumatic telescopic rod 7 through the connecting pipe 9, causing the output end of the pneumatic telescopic rod 7 to gradually contract. During the contraction of the output end of the pneumatic telescopic rod 7, the sealing plate 8 is disengaged from the exhaust groove 6. Then, during the upward movement of the piston plate 202, the airflow above the piston plate 202 in the cylinder 201 can flow normally to the outside through the air hole. When the locking rod 301 is inserted into the locking groove 302, the slide groove draws air from the pneumatic telescopic rod 7 through the connecting pipe 9. Then, the output end of the pneumatic telescopic rod 7 extends and causes the sealing plate 8 to block the air hole, thereby increasing the resistance to the movement of the piston plate 202 and further improving safety.

[0038] Specifically, such as Figure 3 As shown, an iron core 11 that cooperates with the coil 4 is fixedly installed on the piston plate 202.

[0039] The end of the locking rod 301 away from the first spring 303 is an inclined surface.

[0040] The surface of the locking groove 302 is a smooth mirror surface.

[0041] By adopting the above technical solution, during the process of coil 4 being energized and generating a magnetic field, iron core 11 generates an induced magnetic field. Then, the two magnetic fields are superimposed, thereby increasing the magnetic field strength of magnet block 5. This ensures that magnet block 5 can normally drive locking rod 301 to move under the action of magnetic force. Furthermore, by making the end of locking rod 301 away from spring 303 be inclined, it is easier for locking rod 301 to be inserted into locking groove 302. In addition, by making the surface of locking groove 302 a smooth mirror surface, the friction between locking rod 301 and locking groove 302 can be reduced, ensuring that locking rod 301 moves normally along locking groove 302, which plays a role in improving the operational stability of the device.

[0042] Working principle: When the pressure inside the filter cartridge 1 is too high and causes the cartridge cover 12 to move upward, the space below the piston plate 202 in the cylinder body 201 draws air from the slide groove through the groove 306, causing the locking rod 301 to insert into the locking groove 302, thereby fixing the piston plate 202 and thus fixing the cartridge cover 12. When the cylinder 2 leaks air, the pressure below the piston plate 202 in the cylinder body 201 decreases. At this time, the spring 303 extends and causes the locking rod 301 to insert into the locking groove 302, thereby limiting the piston plate 202 and thus fixing the cartridge cover 12.

[0043] Furthermore, as the two locking rods 301 approach each other, the airflow in the groove is compressed and flows into the pneumatic telescopic rod 7 through the connecting pipe 9, causing the output end of the pneumatic telescopic rod 7 to gradually contract. During the contraction of the output end of the pneumatic telescopic rod 7, when the sealing plate 8 is disengaged from the exhaust groove 6, the airflow above the piston plate 202 in the cylinder 201 can flow normally to the outside through the air hole during the upward movement of the piston plate 202. When the locking rod 301 is inserted into the locking groove 302, the groove draws air from the pneumatic telescopic rod 7 through the connecting pipe 9. Then, the output end of the pneumatic telescopic rod 7 extends and causes the sealing plate 8 to block the air hole, thereby increasing the resistance to the movement of the piston plate 202.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
