Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter technology, specifically to a device for quick disassembly of a pressure transmitter. Background Technology

[0002] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure sensing element sensor into standard electrical signals to supply secondary instruments such as indicators, alarms, recorders, and regulators for measurement, indication, and process regulation.

[0003] For example, an existing Chinese patent (publication number: CN217738537U) discloses a quick disassembly and assembly device for a pressure transmitter. The sliding unlocking mechanism includes a connecting rod fixed to one side of the locking block. A first hollow groove communicating with the T-shaped placement groove is opened on one side of the mounting block. The connecting rod is slidably disposed in the first hollow groove.

[0004] However, the quick-release device for pressure transmitters designed above still has some drawbacks in actual use: although the quick-release device for pressure transmitters can be used to disassemble and install pressure transmitters by means of snap-fit, the disassembly structure is located on the outside of the mounting block during disassembly, which makes it easy to cause instability due to external touch or other factors.

[0005] To address this issue, we designed a quick disassembly device for pressure transmitters. Utility Model Content

[0006] The purpose of this invention is to provide a quick disassembly device for pressure transmitters to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a quick disassembly device for a pressure transmitter, including a mounting base, a pressure transmitter body disposed at the top center of the mounting base, and a mounting component fixedly installed at the bottom center of the pressure transmitter body. The mounting component is slidably inserted into the top of the mounting base, and further includes...

[0008] The sliding component is arranged vertically and is slidably disposed within the mounting base;

[0009] The locking strip is set perpendicular to the slider, and the other end is slidably inserted into one side of the mounting piece;

[0010] The support spring is fixedly installed at both ends on one side of the slide and the inner wall of the mounting base, respectively.

[0011] The iron block is fixedly installed on the side of the slider away from the locking strip.

[0012] Furthermore, the mounting component has a fixing groove on the side near the locking strip, and the side of the locking strip away from the slider is slidably inserted into the fixing groove.

[0013] Furthermore, there are two iron blocks, which are symmetrically installed on the side of the slider away from the locking strip, and the support spring is located between the two iron blocks.

[0014] Furthermore, the top and interior of the mounting base are respectively provided with a fixing port and a cavity, the fixing port and the cavity are connected, the mounting component is slidably inserted into the fixing port, the sliding component is slidably connected into the cavity, and the end of the support spring away from the sliding component is fixedly installed on the inner side wall of the cavity.

[0015] Furthermore, a telescopic rod is fixedly installed between the sliding member and the inner wall of the cavity, and the support spring is movably sleeved on the telescopic rod.

[0016] Furthermore, a placement groove is provided on one side of the mounting base, and the placement groove is located on one side of the two iron blocks.

[0017] Furthermore, limit strips are fixedly installed at the top and bottom of the slider, and a rotating groove is provided on the limit strip. A ball is rotatably disposed in the rotating groove. Two guide rails are symmetrically provided in the mounting base. The guide rails are connected to the cavity, and the ball is rotatably connected in the guide rails.

[0018] Furthermore, a positioning groove is provided on one side of the top of the mounting base. The positioning groove is triangular in shape. A horizontal bar is fixedly installed on the bottom of one side of the pressure transmitter body. A positioning strip is provided at the bottom of the horizontal bar. The shape of the positioning strip is adapted to the positioning groove and its bottom end is slidably inserted into the positioning groove.

[0019] Furthermore, mounting plates are fixedly installed on the bottom of both sides of the mounting base, and multiple bolts are threaded into the top of the mounting plates.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the permanent magnet on one side of the mounting base, the permanent magnet can attract the iron block and drive the slider and the locking strip to slide to the left and slide out of the fixing groove, which can release the limitation on the mounting part. Finally, by pulling the pressure transmitter body upward, the pressure transmitter body can be driven to slide the mounting part out of the fixing port, which can facilitate the disassembly of the pressure transmitter body. Moreover, since all disassembly and assembly structures are located inside the cavity, the pressure transmitter quick disassembly device is not easily affected by external factors and is not prone to poor stability.

[0021] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the limiting strip, the ball and the guide rail, the sliding part can drive the ball to roll in the guide rail during the sliding process. This not only limits the sliding part, but also changes the sliding friction of the sliding part in the cavity to rolling friction, thereby reducing the friction force when the sliding part slides, making it easier for the external permanent magnet to attract the sliding part to slide to the left.

[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 Figure 1-4 This utility model provides a technical solution: a quick disassembly device for a pressure transmitter, including a mounting base 1, a pressure transmitter body 2 disposed at the top center of the mounting base 1, and a mounting component 3 fixedly installed at the bottom center of the pressure transmitter body 2. The mounting component 3 is slidably inserted into the top of the mounting base 1, and also includes...

[0029] The slider 4 is arranged vertically and is slidably disposed within the mounting base 1;

[0030] The locking strip 5 is set perpendicular to the slider 4, and its other end is slidably inserted into one side of the mounting part 3;

[0031] The support spring 6 is fixedly installed at both ends on one side of the slide 4 and the inner side wall of the mounting base 1;

[0032] Iron block 20 is fixedly installed on the side of slide 4 away from the retaining strip 5;

[0033] The mounting part 3 has a fixing groove 7 on the side near the clip 5. The side of the clip 5 away from the slide 4 is slidably inserted into the fixing groove 7. The top and the inside of the mounting base 1 have fixing openings 8 and cavities 9 respectively. The fixing openings 8 and cavities 9 are connected. The mounting part 3 is slidably inserted into the fixing opening 8. The slide 4 is slidably connected to the cavity 9. The end of the support spring 6 away from the slide 4 is fixedly installed on the inner wall of the cavity 9.

[0034] In practice, when it is necessary to remove the pressure transmitter body 2 from the top of the mounting base 1, a permanent magnet is first prepared. Then, the permanent magnet is pressed against one side of the mounting base 1. At this time, the permanent magnet will attract the iron block 20 and drive the slider 4 and the locking strip 5 to slide to the left in the cavity 9 and compress the support spring 6. During this process, one end of the locking strip 5 will slide out from the fixing groove 7, which can release the restriction on the mounting part 3. Finally, by pulling the pressure transmitter body 2 upward, the pressure transmitter body 2 can be moved to slide the mounting part 3 out of the fixing port 8, which can facilitate the disassembly of the pressure transmitter body 2. In addition, since the disassembly and assembly structure is located inside the cavity 9, the pressure transmitter quick disassembly device is not easily affected by external factors and will not have poor stability.

[0035] See Figure 1-4 There are two iron blocks 20, which are symmetrically installed on the side of the slider 4 away from the retaining strip 5, and the supporting spring 6 is located between the two iron blocks 20. The arrangement of the two iron blocks 20 can increase the attraction strength of the permanent magnet to the slider 4.

[0036] See Figure 1-4 A telescopic rod 10 is also fixedly installed between the slider 4 and the inner wall of the cavity 9, and the support spring 6 is movably sleeved on the telescopic rod 10. This allows the slider 4 to slide only along the telescopic end of the telescopic rod 10, avoiding the problem of the slider 4 tilting during movement.

[0037] See Figure 1-4 A placement groove 11 is provided on one side of the mounting base 1, and the placement groove 11 is located on one side of the two iron blocks 20.

[0038] In specific implementation, based on the above implementation, the permanent magnet is placed in the placement groove 11. Since the placement groove 11 is located on one side of the two iron blocks 20, it can help improve the attraction effect on the slider 4.

[0039] See Figure 1-4Limiting strips 12 are fixedly installed on the top and bottom of the sliding part 4. A rotating groove is provided on the limiting strip 12, and a ball bearing 13 is rotatably arranged in the rotating groove. Two guide rails 14 are symmetrically arranged in the mounting base 1. The guide rails 14 are connected to the cavity 9, and the ball bearing 13 is rotatably connected in the guide rails 14.

[0040] In specific implementation, based on the above implementation, during the sliding process of the upper slider 4, the slider 4 will drive the ball 13 to roll in the guide rail 14, which can not only limit the slider 4, but also change the sliding friction of the slider 4 in the cavity 9 into rolling friction, thereby reducing the friction force when the slider 4 slides, so that the external permanent magnet can more easily attract the slider 4 to slide to the left.

[0041] See Figure 1-4 A positioning groove 15 is provided on one side of the top of the mounting base 1. The positioning groove 15 is triangular in shape. A horizontal bar 16 is fixedly installed on the bottom of one side of the pressure transmitter body 2. A positioning bar 17 is provided at the bottom of the horizontal bar 16. The shape of the positioning bar 17 is adapted to the positioning groove 15 and its bottom end is slidably inserted into the positioning groove 15.

[0042] In specific implementation, based on the above implementation, by inserting the positioning strip 17 into the positioning groove 15, not only can the pressure transmitter body 2 be simply positioned, making it convenient to install the pressure transmitter body 2, but the shape of the positioning groove 15 can also be used to avoid installing the pressure transmitter body 2 backwards.

[0043] See Figure 1-4 Mounting plates 18 are fixedly installed on the bottom of both sides of the mounting base 1, and multiple bolts 19 are threaded into the top of the mounting plates 18. Rotating the bolts 19 allows the bolts 19 to rotate and move downwards, which facilitates the stable installation of the pressure transmitter.

[0044] Working principle: When using the pressure transmitter body 2, it is necessary to remove it from the top of the mounting base 1. First, a permanent magnet is prepared. Then, the permanent magnet is placed in the placement groove 11. At this time, the permanent magnet will attract the iron block 20 and drive the slider 4 and the locking strip 5 to slide to the left in the cavity 9 and compress the support spring 6. During this process, one end of the locking strip 5 will slide out from the fixing groove 7, which can release the limitation on the mounting part 3. Finally, by pulling the pressure transmitter body 2 upward, the pressure transmitter body 2 can be driven to slide the mounting part 3 out of the fixing port 8, which can facilitate the removal of the pressure transmitter body 2. In addition, since the disassembly and assembly structure is located inside the cavity 9, the pressure transmitter quick disassembly device is not easily affected by external factors and will not have poor stability.

[0045] It should be noted that during the sliding process of the slider 4, the slider 4 will drive the ball 13 to roll in the guide rail 14. This not only limits the slider 4, but also changes the sliding friction of the slider 4 in the cavity 9 to rolling friction, thereby reducing the friction force when the slider 4 slides, making it easier for the external permanent magnet to attract the slider 4 to slide to the left.

[0046] Finally, it should be noted that by inserting the positioning strip 17 into the positioning groove 15, not only can the pressure transmitter body 2 be easily positioned and installed, but the shape of the positioning groove 15 can also be used to prevent the pressure transmitter body 2 from being installed backwards.
