Description

Technical Field

[0001] This utility model belongs to the field of pressure controllers, specifically, it relates to a pressure controller that is easy to install. Background Technology

[0002] A pressure controller is an instrument used to monitor and control fluid pressure. Its core function is to trigger a switch action when the controlled pressure reaches a preset threshold in order to maintain pressure stability or achieve safety protection.

[0003] Chinese Patent CN222680902U discloses an auxiliary device for installing a pressure controller body, including a pressure controller body, a mounting plate fixedly installed on one side of the pressure controller body, a mounting screw fixedly connected to the lower part of the mounting plate, and a toolbox fixedly installed on one side of the pressure controller body. This application installs the pressure controller body and mounting plate together, then uses a connecting plate to connect it to other equipment. However, in this solution, the pressure controller body and mounting plate are installed as a single unit. This means that when replacing the pressure controller, the mounting plate containing the pressure controller body must be removed from other equipment, and then the pressure controller body and mounting plate must be disassembled, which is inconvenient. Although there are detachable installation methods in the prior art, they are usually bolted connections, requiring the use of tools such as wrenches during disassembly and assembly. This not only increases the number of steps required to remove the bolts but may also hinder the pressure controller replacement work due to the use of unsuitable tools. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pressure controller that is easy to install, thus solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install pressure controller includes:

[0007] A connecting plate, with a pressure controller body on one side, and two positioning blocks on one side of the pressure controller body;

[0008] Two connecting mechanisms are slidably fitted inside the connecting plate, with the connecting mechanisms passing through the positioning block. The connecting plate has movable rods inside for moving the connecting mechanisms. The lower part of the connecting plate has a linear drive mechanism slidably fitted to move the two movable rods.

[0009] Two orifice-shaped limit rods are located at the bottom of the connecting plate and are used to limit the movement of the linear drive mechanism. A U-shaped block is installed on the lower side of the connecting plate to limit the rotation of the orifice-shaped limit rods.

[0010] Optionally, the linear drive mechanism includes a connecting block that slides inside the connecting plate, a slide rod is mounted on the lower side of the connecting block, the lower end of the slide rod extends to the outside of the connecting plate, and a bearing block is mounted on the lower end face of the slide rod.

[0011] Optionally, limiting blocks are installed on both sides of the connecting block, and sliding grooves are provided on both sides of the inner wall of the connecting plate, with the limiting blocks slidingly engaged in the sliding grooves.

[0012] Optionally, the connecting mechanism includes concave blocks that slide within the connecting plate, with fixing blocks mounted on the opposite outer sides of the two concave blocks.

[0013] Optionally, a guide groove is provided on one side of the inner wall of the connecting plate, and a guide block is installed on one side of the concave block, with both guide blocks slidingly engaged in the guide groove.

[0014] Optionally, the connecting plate has two positioning slots on one side, and the positioning block is engaged in the positioning slot.

[0015] Optionally, the ends of the two mouth-shaped limiting rods that are close to each other are elastically and rotatably fitted within the bearing block, while the ends of the mouth-shaped limiting rods that are away from the bearing block are engaged within the U-shaped block.

[0016] Optionally, connecting shafts are installed on both inner walls of the bearing block, and the end of the orifice-shaped limiting rod away from the U-shaped block is rotatably fitted onto the connecting shaft.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] By cooperating with the linear drive mechanism, movable rod, connecting mechanism, and orifice-shaped limiting rod, an integrated linkage mechanism is formed. This allows operators to quickly assemble and disassemble the connecting plate and the pressure controller body simply by operating the orifice-shaped limiting rod, simplifying the pressure controller body replacement process, improving replacement efficiency, and reducing tool usage. At the same time, after the orifice-shaped limiting rod is engaged in the U-shaped block, the linear drive mechanism, movable rod, and connecting mechanism can be fixed, making it difficult for the connecting mechanism to detach from the positioning block, thereby improving the stability of the connecting plate and the pressure controller body after installation.

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figure 1-6 As shown, this embodiment provides a pressure controller that is easy to install, including:

[0032] A connecting plate 1 is provided with a pressure controller body 2 on one side of the connecting plate 1, and two positioning blocks 201 are installed on one side of the pressure controller body 2.

[0033] Two connecting mechanisms 5 are slidably fitted inside the connecting plate 1. The connecting mechanisms 5 pass through the positioning block 201. A movable rod 4 for moving the connecting mechanisms 5 is movably fitted inside the connecting plate 1. A linear drive mechanism 3 for moving the two movable rods 4 is slidably fitted at the lower part of the connecting plate 1.

[0034] Two orifice-shaped limiting rods 6 are located at the bottom of the connecting plate 1 and are used to limit the movement of the linear drive mechanism 3. A U-shaped block 7 is installed on the lower side of the connecting plate 1 to limit the rotation of the orifice-shaped limiting rods 6.

[0035] Optionally, two docking blocks 101 are installed on both the upper and lower sides of the connecting plate 1, and a docking hole 102 is passed through the middle of the docking block 101. Through the docking hole 102 opened on the docking block 101, the connecting plate 1 can be connected to other equipment, thereby realizing the installation of the pressure controller body 2 with other equipment.

[0036] One application of this embodiment is as follows: When disassembling the pressure controller body 2 from the connecting plate 1, by squeezing the two orifice-shaped limiting rods 6 towards the pressure controller body 2, the orifice-shaped limiting rods 6 rotate at the rotation point on the linear drive mechanism 3 and disengage from the U-shaped block 7. Then, by pulling the orifice-shaped limiting rods 6, the linear drive mechanism 3 pulls the two movable rods 4 downward. During the movement of the movable rods 4, the connecting mechanism 5 is pulled away from the positioning block 201, thereby releasing the fixation of the pressure controller body 2. When installing the pressure controller body 2 from the connecting plate 1, the positioning block 201 is snapped into the connecting plate 1. At this time, pushing the orifice-shaped limiting rods 6 upward causes the linear drive mechanism 3, the movable rods 4, and the connecting mechanism 5 to move back to their original positions simultaneously, allowing the connecting mechanism 5 to insert into the positioning block 201. Then, the orifice-shaped limiting rods 6 are released, allowing them to reset and re-snap into the U-shaped block 7 under the action of elasticity. It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0037] The linear drive mechanism 3, movable rod 4, connecting mechanism 5, and orifice-shaped limiting rod 6 work together to form an integrated linkage mechanism. This allows operators to quickly assemble and disassemble the connecting plate 1 and the pressure controller body 2 by operating the orifice-shaped limiting rod 6, simplifying the replacement process of the pressure controller body 2, improving replacement efficiency, and reducing tool usage. At the same time, after the orifice-shaped limiting rod 6 is engaged in the U-shaped block 7, the linear drive mechanism 3, movable rod 4, and connecting mechanism 5 can be fixed, making it difficult for the connecting mechanism 5 to detach from the positioning block 201, thereby improving the stability of the connecting plate 1 and the pressure controller body 2 after installation.

[0038] To achieve simultaneous pulling of both movable levers 4, such as Figure 3-5 As shown, the linear drive mechanism 3 in this embodiment includes a connecting block 303 that slides inside the connecting plate 1. A slide rod 301 is mounted on the lower side of the connecting block 303, and the lower end of the slide rod 301 extends to the outside of the connecting plate 1. A bearing block 302 is mounted on the lower end face of the slide rod 301. Optionally, the connecting block 303 has an I-shaped cross-section, and a first connecting rod 304 is mounted between the inner walls of both ends of the connecting block 303. The end of the movable rod 4 away from the connecting mechanism 5 is rotatably engaged with the first connecting rod 304.

[0039] When the orifice-shaped limiting rod 6 is pulled down, the bearing block 302, the sliding rod 301, the connecting block 303 and the first connecting rod 304 can move downwards simultaneously. At this time, under the action of the first connecting rod 304, the movable rod 4 can be pulled to move, so that the connecting mechanism 5 can move smoothly in the subsequent movement.

[0040] To improve the overall movement stability of the linear drive mechanism 3, such as Figure 3-5 As shown, in this embodiment, limiting blocks 306 are installed on both sides of the connecting block 303, and sliding grooves 104 are provided on both sides of the inner wall of the connecting plate 1. The limiting blocks 306 are slidably fitted in the sliding grooves 104.

[0041] During the movement of the connecting block 303, the limiting block 306 will slide within the slide groove 104. At this time, under the action of the limiting block 306 and the slide groove 104, the movement direction of the linear drive mechanism 3 as a whole can be restricted, reducing the probability of wobbling and improving the stability of the linear drive mechanism 3 during its overall movement.

[0042] To facilitate quick assembly and disassembly between the connecting plate 1 and the pressure controller body 2, such as Figure 3-5As shown, the connecting mechanism 5 in this embodiment includes a concave block 501 that slides inside the connecting plate 1, and a fixing block 502 is installed on the opposite outer sides of the two concave blocks 501. Optionally, a second connecting rod 503 is installed between the two sides of the inner wall of the concave block 501. The end of the movable rod 4 away from the connecting block 303 is rotatably fitted on the second connecting rod 503. The hole-shaft fit tolerance between the movable rod 4 and the first connecting rod 304 and the second connecting rod 503 is H8 / f7, which realizes the smooth rotation of the movable rod 4. A fixing groove 202 passes through the middle of the positioning block 201, and one end of the fixing block 502 is located in the fixing groove 202.

[0043] When the orifice-shaped limiting rod 6 is pulled down, the movable rod 4 will pull the fixing block 502 through the second connecting rod 503, causing it to be pulled out of the fixing groove 202, releasing the fixing of the positioning block 201, thereby releasing the fixing between the connecting plate 1 and the pressure controller body 2, and then the pressure controller body 2 can be removed from the connecting plate 1 for replacement; when installing the connecting plate 1 and the pressure controller body 2, after the pressure controller body 2 is re-clamped onto the connecting plate 1, the orifice-shaped limiting rod 6 is pushed up, so that the fixing block 502 can be re-inserted into the fixing groove 202, thereby fixing the positioning block 201, thus quickly completing the installation between the connecting plate 1 and the pressure controller body 2.

[0044] To improve the movement stability of the concave block 501, such as Figure 3 and Figure 5 As shown, in this embodiment, the inner wall of the connecting plate 1 is provided with a guide groove 105, and the concave block 501 is provided with a guide block 504 on one side. Both guide blocks 504 are slidably fitted in the guide groove 105.

[0045] During the movement of the concave block 501, the guide block 504 will slide within the guide groove 105. At this time, under the action of the guide block 504 and the guide groove 105, the movement direction of the concave block 501 can be restricted, its vertical swaying can be reduced, and the stability of the concave block 501 during the movement can be improved, so that the fixing block 502 can be smoothly inserted into or detached from the fixing groove 202.

[0046] In order to make the fixing block 502 snap into the fixing slot 202, such as Figure 2 and Figure 5 As shown, the connecting plate 1 in this embodiment has two positioning grooves 103 on one side. The positioning block 201 is snapped into the positioning groove 103. The fit tolerance between the width of the positioning block 201 and the width of the positioning groove 103 is H7 / g6, which not only allows the positioning block 201 to be smoothly inserted into the positioning groove 103, but also reduces the shaking caused by excessive size.

[0047] When installing the pressure controller body 2 and the connecting plate 1, by inserting the positioning block 201 into the positioning groove 103, the fixing groove 202 on the positioning block 201 can be horizontally aligned with the fixing block 502, laying the foundation for the subsequent smooth insertion of the fixing block 502 into the fixing groove 202 and further improving the accuracy of the installation operation.

[0048] To achieve the fixation of the linear drive mechanism 3, such as Figure 3-6 As shown, in this embodiment, the ends of the two mouth-shaped limiting rods 6 that are close to each other are elastically and rotatably fitted in the bearing block 302, and the ends of the mouth-shaped limiting rods 6 that are away from the bearing block 302 are engaged in the U-shaped block 7.

[0049] When the orifice-shaped limiting rod 6 is engaged in the U-shaped block 7, it can fix the linear drive mechanism 3, thereby restricting the movement of the linear drive mechanism 3, making it difficult for the connecting mechanism 5 to detach from the fixing groove 202, and improving the stability of the pressure controller body 2 after installation.

[0050] To improve the stability of the orifice-shaped limiting rod 6 within the U-shaped block 7, such as Figure 4 and Figure 6 As shown, in this embodiment, the inner walls of both sides of the bearing block 302 are equipped with connecting shafts 305. The vertical cross-section of the bearing block 302 is an I-shaped structure. The connecting shafts 305 are installed between the upper and lower sides of the inner wall of one end of the bearing block 302. The end of the orifice-shaped limiting rod 6 away from the U-shaped block 7 is rotatably fitted on the connecting shaft 305. The orifice-shaped limiting rod 6 is provided with a torsion spring 601 inside. The torsion spring 601 is sleeved on the periphery of the connecting shaft 305, and one end of the torsion spring 601 is stuck inside the connecting shaft 305, and the other end is stuck on the inner wall side of the orifice-shaped limiting rod 6.

[0051] Because the elastic force of the torsion spring 601 can apply a certain torque to the mouth-shaped limiting rod 6, the mouth-shaped limiting rod 6 can maintain the engagement state with the U-shaped block 7 in its natural state, reducing the probability of the mouth-shaped limiting rod 6 disengaging from the U-shaped block 7 due to slight external vibration or accidental contact, thus enhancing the reliability of fixing the linear drive mechanism 3. At the same time, when the mouth-shaped limiting rod 6 rotates, it will cause the torsion spring 601 to be in a taut state. When the mouth-shaped limiting rod 6 is released, under the action of the torsion spring 601, the mouth-shaped limiting rod 6 can be quickly engaged in the U-shaped block 7, improving the convenience of installation and operation.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
