Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter installation technology, and in particular to a pressure transmitter device that can be quickly installed and disassembled. Background Technology

[0002] A pressure transmitter is a device that converts pressure into pneumatic or electrical signals for control and remote transmission. It transforms the physical pressure parameters of gases, liquids, etc., sensed by a pressure sensor into standard electrical signals, which are then supplied to secondary instruments such as indicators, alarms, recorders, and controllers for measurement, indication, and process regulation. Pressure transmitters are typically installed by directly connecting to pipelines via threads. However, in practical applications, pressure transmitters are usually fixed to an external rod using brackets and several bolts to ensure operational stability. This bracket and bolt connection method is cumbersome to install and remove, inefficient, requires specific tools, and is not convenient.

[0003] Chinese patent CN219657061U discloses a pressure transmitter assembly that is easy to install. It features a fastening outer ring and a fastening inner ring. The diameters of the outer and inner rings are adjusted by a reset connector clip at different positions within the outer ring. After the mounting flange is connected to an external object, the inner ring is folded into the outer ring. Then, the inner and outer rings are fitted onto the connection point between the mounting flange and the external object. The inner ring is then connected to one end of the outer ring via the reset connector clip, thus securing the mounting flange to the external object and improving the stability of the transmitter body connection. However, it has the following problems:

[0004] 1. The pressure transmitter described above uses a reset component to connect the inner and outer fastening rings at the connection between the mounting flange and the external object, resulting in insufficient connection stability. If the transformer is used in a location requiring high stability, it will not be stable enough.

[0005] 2. The adjustment of the inner and outer fastening rings of the aforementioned pressure transformer is cumbersome. It requires manual labor to accurately locate the appropriate connection position, which is inconvenient, wastes time, is inefficient, and results in high labor costs. Utility Model Content

[0013] In one embodiment of the present invention, the clamping rod assembly further includes a guide rod disposed in the mounting frame; the guide rod extends along the moving direction of the gripper; and two movable plates are slidably connected to the guide rod respectively.

[0014] In one embodiment of this utility model, a detachable baffle is provided on one side of the mounting frame, and a movable groove is provided on the baffle, through which the gripper extends out of the mounting frame.

[0015] In one embodiment of this utility model, the inner wall of the gripper is provided with anti-slip texture.

[0016] In one embodiment of this utility model, the limiting component includes an adjusting frame, a first limiting member, a second limiting member, and a reset member; the adjusting frame is connected to the mounting frame; one end of the first limiting member is slidably connected to the adjusting frame, and the other end extends outside the adjusting frame; the reset member is located in the adjusting frame, the axis of the reset member is consistent with the extending direction of the first limiting member and is connected between the first limiting member and the adjusting frame; the second limiting member is coaxially connected to the screw, and the second limiting member cooperates with the first limiting member to realize the locking and unlocking of the power unit and the mounting frame.

[0017] In one embodiment of this utility model, the first limiting member includes a sliding plate, a limiting block, and a limiting rod; the limiting block and the sliding plate are respectively connected to the two ends of the limiting rod; the sliding plate is slidably connected to the adjustment frame; the limiting block extends out of the adjustment frame and cooperates with the second limiting member.

[0021] The pressure transmitter device of this utility model, which allows for quick installation and disassembly, is driven by a power unit and, under the action of a transmission unit, its two grippers can move synchronously and in opposite directions to open and close, thereby gripping and clamping the external rod. Furthermore, this application only requires the power unit to operate to achieve the installation and disassembly of the transmitter body and the external rod, resulting in high work efficiency, simple operation, and strong practicality. In addition, after the grippers clamp the external rod, the limiting component locks the grippers to the mounting frame (meaning the grippers cannot move in the opposite direction to open when locked), thus ensuring the stability of the connection and fixation between the transmitter body and the external rod. This prevents the grippers from loosening due to screw reversal, even in environments with high stability requirements. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0034] It should be noted that in the following text, "front" refers to the end of the screw connected to the drive disc, and "rear" refers to the end of the screw connected to the connecting plate.

[0035] Reference Figures 1-5 As shown, this utility model embodiment provides a pressure transmitter that can be quickly installed and disassembled, including:

[0036] Transmitter body 1;

[0037] The lever assembly 2 is connected to the transmitter body 1. The lever assembly 2 includes a mounting frame 21, a power unit, a transmission unit, and two grippers 27. The mounting frame 21 is connected to the transmitter body 1. The power unit and the transmission unit are respectively connected in the mounting frame 21. The output end of the power unit is connected to the transmission unit. The transmission unit is respectively connected to the two grippers 27. The grippers 27 are slidably connected to the mounting frame 21 and are located outside the mounting frame 21. The power unit drives the two grippers 27 to move synchronously in opposite directions to realize the opening and closing of the two grippers 27, thereby gripping and clamping the external rod 5.

[0038] The limiting component 3 is connected to the transmitter body 1 and located on one side of the lever assembly 2 (for example, the limiting component 3 is connected to the top of the lever assembly 2) to achieve locking and unlocking of the gripper 27 and the mounting frame 21.

[0039] Specifically, in this embodiment, driven by the power unit and under the action of the transmission unit, the two grippers 27 can move synchronously and in opposite directions to open and close, thereby gripping and clamping the external rod 5. Furthermore, this application only requires the power unit to operate to achieve the installation and disassembly of the transmitter body 1 and the external rod 5, resulting in high work efficiency, simple operation, strong practicality, and low labor costs. In addition, after the grippers 27 clamp the external rod 5, the limiting component 3 locks the grippers 27 to the mounting frame 21 (meaning that the grippers 27 cannot move in the opposite direction to open when locked), thus ensuring the stability of the connection and fixation between the transmitter body 1 and the external rod 5. This prevents the grippers 27 from loosening due to the screw 212 reversing, even in environments with high stability requirements.

[0040] Furthermore, the power unit includes a screw 212 and a connecting plate 213; one end of the screw 212 is threadedly connected to the mounting frame 21, and the other end extends into the mounting frame 21 and is rotatably connected to the connecting plate 213; the connecting plate 213 is connected to the transmission unit. Specifically, in this embodiment, rotating the screw 212 causes the end of the screw 212 connected to the transmission unit to move, thereby driving the two grippers 27 to move synchronously in opposite directions under the action of the transmission unit. Specifically, in this embodiment, through a purely mechanical structure, the operator only needs to rotate the screw 212 to realize the opening and closing of the two grippers 27, which is more stable, reliable, and low-cost.

[0041] Furthermore, a drive disc 214 is provided at one end of the screw 212 located outside the mounting frame 21. Specifically, the drive disc 214 facilitates the operator's rotation of the screw 212.

[0042] Furthermore, the drive disk 214 is provided with a protrusion 215. Specifically, the protrusion 215 facilitates the control of the rotation of the drive disk 214.

[0043] Further, the transmission unit includes a rotating shaft 22, a turntable 23, two adjusting rods 24, and two movable plates 25; the turntable 23 is rotatably connected to the mounting frame 21; in some embodiments, the rotating shaft 22 is rotatably connected to the mounting frame 21, and the turntable 23 is connected to the rotating shaft 22. The two adjusting rods 24 are symmetrically and movably connected to the turntable 23; in some embodiments, the adjusting rods 24 are connected to the edge of the upper surface of the turntable 23. The two adjusting rods 24 are symmetrically arranged radially along the turntable 23. The two movable plates 25 are symmetrically arranged on both sides of the turntable 23, and the movable plates 25 correspond one-to-one with the adjusting rods 24, and the movable plates 25 are connected to the ends of the adjusting rods 24; the movable plates 25 are connected to the grippers 27; the screw 212 is connected to one of the two movable plates 25. In some embodiments, the transmission unit also includes two parallel connecting frames 26, the connecting frames 26 correspond one-to-one with the movable plates 25, the movable plates 25 are connected to one end of the connecting frames 26, and the grippers 27 are connected to the other end of the connecting frames 26. This increases the distance between the turntable 23 and the gripper 27, allowing the gripper 27 to extend beyond the mounting frame 21 to grasp and clamp the external rod 5. Specifically, in this embodiment, the rotational power of the screw 212 is converted into the opposite movement of the two grippers 27 through the turntable 23, two adjusting rods 24, and two moving plates 25, resulting in smoother operation.

[0044] Furthermore, the lever assembly 2 also includes a guide rod 28 disposed in the mounting frame 21; the guide rod 28 extends along the moving direction of the gripper 27; two movable plates 25 are respectively slidably connected to the guide rod 28. In some embodiments, one end of the movable plate 25 is provided with a slider 29, and the slider 29 and the guide rod 28 form a sliding pair. Specifically, in this embodiment, the guide rod 28 plays a limiting and guiding role in the sliding of the movable plate 25.

[0045] Furthermore, a detachable baffle 210 is provided on one side of the mounting frame 21, and a moving groove 211 is provided on the baffle 210, through which the gripper 27 extends out of the mounting frame 21. In some embodiments, the baffle 210 is detachably connected to the mounting frame 21 by four bolts. Specifically, the detachable baffle 210 in this embodiment facilitates repair or routine maintenance after damage to internal components.

[0046] Furthermore, the inner wall of the gripper 27 is provided with anti-slip texture 216. The gripper 27 has an arc-shaped structure. Specifically, in this embodiment, the anti-slip texture 216 improves the clamping force of the two grippers 27, thereby improving the stability of the connection between the gripper 27 and the external rod 5.

[0047] When the worker needs to fix the transmitter body 1 to the external rod 5, the protrusion 215 on the rotating drive disc 214 drives the screw 212 to rotate and move forward. Since the connecting plate 213 is rotatably connected to the screw 212, the connecting plate 213 moves, and under the linkage of the turntable 23, the adjusting rod 24 and the moving plate 25, the two moving plates 25 move synchronously in opposite directions. The two moving plates 25 drive the two connecting frames 26 and the grippers 27 to move closer to each other, so that the two grippers 27 clamp and fix them to the outer wall of the external rod 5, thereby fixing the transmitter body 1. This facilitates the installation and disassembly of the pressure transmitter and improves work efficiency.

[0048] In practical applications, simply rotating the screw 212 is sufficient to fix the transmitter body 1 onto the external rod 5, making the operation simple and highly practical.

[0049] Furthermore, the limiting assembly 3 includes an adjusting frame 35, a first limiting member, a second limiting member 34, and a reset member 311 (e.g., a spring); the adjusting frame 35 is connected to the mounting frame 21; one end of the first limiting member is slidably connected in the adjusting frame 35, and the other end extends outside the adjusting frame 35; the reset member 311 is located in the adjusting frame 35, and the axis of the reset member 311 is aligned with the extending direction of the first limiting member and connects between the first limiting member and the adjusting frame 35; the second limiting member 34 is coaxially connected to the screw 212, and the second limiting member 34 cooperates with the first limiting member to lock and unlock the power unit from the mounting frame 21. The reset member 311 causes the first limiting member to cooperate with the second limiting member 34.

[0050] Furthermore, the first limiting member includes a sliding plate 36, a limiting block 38, and a limiting rod 37; the limiting block 38 and the sliding plate 36 are respectively connected to both ends of the limiting rod 37; the sliding plate 36 is slidably connected in the adjusting frame 35; the limiting block 38 extends out of the adjusting frame 35 and cooperates with the second limiting member 34. Specifically, the sliding plate 36 cooperates with the inner wall of the adjusting frame 35 for guidance, making the up-and-down movement of the first limiting member more stable and reliable.

[0051] Furthermore, the portion of the first limiting member that mates with the second limiting member 34 (i.e., the limiting block 38) has a vertical locking plane 31 and an arc-shaped guide plane 32 on its front and rear sides, respectively, and the vertical locking plane 31 and the arc-shaped guide plane 32 are connected. The second limiting member 34 has a conical structure, and the diameter of the conical structure gradually increases from front to back. The arc-shaped guide plane 32 mates with the conical structure of the second limiting member 34 to realize the opening and closing of the gripper 27. The vertical locking plane 31 mates with the end face of the second limiting member 34 to realize locking. Specifically, in this embodiment, the opening and closing of the gripper 27 and the locking after clamping are realized by the arc-shaped guide plane 32 or the vertical locking plane 31 mates with the second limiting member 34. The structure is simple and the locking effect is good.

[0052] Furthermore, the limiting component 3 also includes a pull rod 39; one end of the pull rod 39 is located in the adjusting frame 35 and connected to the first limiting member, and the other end of the pull rod 39 extends beyond the adjusting frame 35; a reset member 311 is sleeved on the pull rod 39. Specifically, in this embodiment, pulling the pull rod 39 can pull the first limiting member to disengage it from the second limiting member 34, thereby achieving unlocking. In some embodiments, the end of the pull rod 39 extending beyond the adjusting frame 35 is provided with a protrusion 310 with a diameter larger than that of the pull rod 39. This facilitates the operator's gripping of the protrusion 310 and the step of the pull rod 39 for easier operation.

[0053] Furthermore, a waterproof connector 4 is connected to the transmitter body 1, and the leads of the transmitter body 1 are electrically connected to the external host computer through the waterproof connector 4. Specifically, the waterproof connector 4 can prevent water and other substances from entering the transmitter body 1 and affecting the circuit connection and equipment operation.

[0054] When the screw 212 rotates forward, the second limiting member 34 engages with the arc-shaped guide plane 32 and overcomes the elastic force of the reset member 311 to press the arc-shaped guide plane 32 of the first limiting member, causing the first limiting member to move upward. At this time, as it gradually moves forward, the engagement of the second limiting member 34 and the arc-shaped guide plane 32 ensures the stable forward movement of the screw 212, so that the two grippers 27 gradually close to clamp the external rod 5. When the two grippers 27 just clamp the external rod 5, the arc-shaped guide plane 32 disengages from the conical surface 33 of the second limiting member 34. In this way, the first limiting member loses the pressure on the conical surface 33 of the second limiting member 34 and is reset by the reset member 311, so that the vertical locking plane 31 of the first limiting member abuts against the end face of the second limiting member 34. If the screw 212 rotates in the opposite direction, the engagement of the vertical locking plane 31 with the end face of the second limiting member 34 achieves locking (i.e., the two grippers 27 cannot open). This prevents the jaws 27 from loosening due to the screw 212 moving backwards, even in environments with high stability requirements. When disassembly is required, pulling up the lever 39 disengages the first limiting member from the second limiting member 34, thus unlocking the transmitter.

[0055] In actual use, the transmitter body 1 is first connected to the pipe thread, and then the external rod 5 is placed between the two jaws 27. The jaws 27 are used to clamp the external rod 5. The external rod 5 ensures the stability of the transmitter.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
