Technical Field

[0001] The utility model relates to the technical field of pressure controllers, in particular to a pressure controller convenient for adjustment. Background Technique

[0002] A pressure controller is a device specifically used to monitor and control the pressure of a fluid system, often used on water pumps. The pressure controller detects the pressure value of the system in real time through a pressure sensor, and feeds the detected pressure value back to the controller as the basis for adjusting the control output. The pressure controller allows users to set a target pressure value, and can automatically adjust the control output according to the actual pressure situation to keep the system pressure within the set range. When the system pressure exceeds the preset upper and lower limit values, the pressure controller will send an alarm signal or automatically cut off relevant equipment to prevent system damage.

[0003] In the existing related technologies, there are often the following defects: Staff can adjust the upper and lower limit values of the water pressure by operating the adjustment buttons. When the installation height of the pressure controller is relatively high, it is inconvenient for the staff to directly adjust and control the pressure controller at a high place, thus reducing the use effect of the pressure controller.

[0004] Therefore, the utility model provides a pressure controller convenient for adjustment. Content of the Utility Model

The control structure includes a limit frame fixedly connected to the surface of the housing, a sliding plate is slidably connected inside the limit frame, a pressing block is fixedly installed at the other end of the sliding plate, and a pulling rope is fixedly connected to the surface of the sliding plate.

[0007] The effects achieved by the above components are as follows: By setting the control structure, it is convenient to adjust the adjustment buttons at a high place from a low place, meeting the use requirements of users of different heights.

[0008] Preferably, a plurality of connecting strips in pairs are fixedly connected to the lower side of the limit frame, and a pulley is rotatably connected to one side of the two connecting strips close to each other.

[0009] The effects achieved by the above components are as follows: The pulling rope slides on the surface of the pulley, achieving the effect of changing the acting direction of the pulling force of the pulling rope. At this time, the pulling work of the skateboard inside the limiting frame can be realized.

[0010] Preferably, the other end of the pulling rope is fixedly connected with a winding rod.

[0011] The effects achieved by the above components are as follows: By winding the pulling rope on the surface of the winding rod, the adjustment work of the used length of the pulling rope can be realized.

[0012] Preferably, circular plates are fixedly installed at both ends of the winding rod.

[0013] The effects achieved by the above components are as follows: By arranging two circular plates, the shielding work of the wound pulling rope is facilitated.

[0014] Preferably, a bolt is threadedly inserted into one of the two circular plates.

[0015] The effects achieved by the above components are as follows: After the pulling rope is wound up a certain length, rotate the bolt inside one of the circular plates and squeeze the bolt against the position where it abuts against the surface of the other circular plate, which can prevent the wound pulling rope from spreading after being loosened.

[0016] Preferably, a protective structure is provided on the surface of the outer shell. The protective structure includes a rectangular block fixedly connected to the surface of the outer shell.

The size of the bolt pin is adapted to the size of the insertion holes. A stop block is fixedly installed at the other end of the bolt pin. A spring is fixedly connected between the rectangular block and the stop block.

[0019] The effects achieved by the above components are as follows: When the pressure controller needs to be carried, the slide bar inside the rectangular block can be pulled. When the insertion holes on the slide bar move to the position corresponding to the bolt pin, the bolt pin will be inserted into the inner side of the insertion holes under the elastic force of the spring between the rectangular block and the stop block, so as to realize the fixing work of the position of the moved slide bar.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Refer to Figure 1As shown, the utility model provides a technical solution: a pressure controller that is easy to adjust, including a shell 1, a display 2 is fixedly installed on the surface of the shell 1, a mounting tube 3 is connected to the lower surface of the shell 1, four adjustment buttons 4 are evenly installed on the surface of the shell 1, a control structure 5 is provided on the surface of the shell 1, and a protective structure 6 is provided on the surface of the shell 1.

[0030] The following describes in detail the specific settings and functions of the control structure 5 and the protection structure 6.

[0031] Reference Figures 1-4 As shown, in this embodiment, the control structure 5 includes a limit frame 55 fixedly connected to the surface of the housing 1. A slide plate 56 is slidably connected to the interior of the limit frame 55. A pressure block 57 is fixedly mounted on the other end of the slide plate 56. A pull cord 51 is fixedly connected to the surface of the slide plate 56. The provision of the control structure 5 facilitates the adjustment of the height adjustment button 4 from a low position, meeting the needs of users of different heights.

[0032] The lower side of the limiting frame 55 is fixedly connected to a number of connecting bars 58, arranged in pairs. The sides of the two connecting bars 58 that are closest to each other are rotatably connected to pulleys 59. The pull rope 51 slides on the surface of the pulley 59, changing the direction of the pulling force on the pull rope 51 and thereby enabling the sliding plate 56 to be pulled inside the limiting frame 55. The other end of the pull rope 51 is fixedly connected to a winding rod 54. By winding the pull rope 51 around the surface of the winding rod 54, the length of the pull rope 51 can be adjusted. A circular plate 52 is fixedly mounted on each end of the winding rod 54. The two circular plates 52 facilitate shielding the wound pull rope 51. A bolt 53 is threadedly inserted into one of the two circular plates 52. After the pull rope 51 is wound to a certain length, the bolt 53 inside one of the circular plates 52 is rotated to press the bolt 53 against the surface of the other circular plate 52, preventing the wound pull rope 51 from unraveling after release.

[0033] Reference Figures 1-2 and Figure 5As shown, specifically, the protection structure 6 includes a rectangular block 63 fixedly connected to the surface of the housing 1. A slide bar 61 is slidably connected inside the rectangular block 63, and a limiting ring 62 is fixedly installed on the lower side of the slide bar 61. The limiting ring 62 protects the port position of the installation pipe 3, avoiding the phenomenon that the port position of the installation pipe 3 is easily deformed after being impacted. A jack 65 is formed on the surface of the slide bar 61, and a plug pin 66 is slidably connected inside the rectangular block 63. The size of the plug pin 66 is adapted to the size of the jack 65. A stopper 64 is fixedly installed at the other end of the plug pin 66, and a spring 67 is fixedly connected between the rectangular block 63 and the stopper 64. When carrying the pressure controller, the slide bar 61 inside the rectangular block 63 can be pulled. When the jack 65 on the slide bar 61 moves to a position corresponding to the plug pin 66, the plug pin 66 is inserted into the inner side of the jack 65 under the elastic force of the spring 67 between the rectangular block 63 and the stopper 64, thereby fixing the position of the moved slide bar 61.

[0034] Working principle: When the installation height of the housing 1 is relatively high and the pressure controller needs to be adjusted, the pull rope 51 is pulled. The pull rope 51 slides on the surface of the pulley 59, achieving the effect of changing the direction of the pulling force of the pull rope 51. At this time, the slide plate 56 can be pulled inside the limiting frame 55. The slide plate 56 drives the pressing block 57 to press the adjustment button 4, facilitating the control of the adjustment button 4. Furthermore, the adjustment of the pressure controller at a high position is realized. By winding the pull rope 51 around the winding rod 54, the use length of the pull rope 51 can be adjusted. By providing two circular plates 52, it is convenient to block the wound pull rope 51. After the pull rope 51 is wound up a certain length, the bolt 53 inside one of the circular plates 52 is rotated, and the bolt 53 is pressed against the position where it abuts against the surface of the other circular plate 52, preventing the wound pull rope 51 from unwinding after being released. By flexibly adjusting the use length of the pull rope 51, it is convenient for users of different heights to operate the adjustment button 4. By providing the control structure 5, it is convenient to adjust the adjustment button 4 at a high position from a low position, meeting the usage requirements of users of different heights.

[0035] When it is necessary to carry the pressure controller, the slide bar 61 inside the rectangular block 63 can be pulled. When the jack 65 on the slide bar 61 moves to a position corresponding to the plug pin 66, the plug pin 66 will be inserted into the inner side of the jack 65 under the elastic force of the spring 67 between the rectangular block 63 and the stop block 64, so as to fix the position of the slide bar 61 after movement. At this time, the limit ring 62 will protect the port position of the installation pipe 3, avoiding the phenomenon that the port position of the installation pipe 3 is easily deformed after being impacted, which will affect the subsequent installation work of the pressure controller. By setting the protection structure 6, it is convenient to protect the pipe orifice position of the installation pipe 3 of the pressure controller, avoiding the direct impact on the pipe orifice position of the installation pipe 3 and improving the safety during the carrying process of the pressure controller.
