Description

Technical Field

[0001] This utility model relates to the fields of technical industrial equipment, laboratories and aerospace, specifically a pressure scanning valve pressure tube insertion and removal clamp. Background Technology

[0002] Pressure scanning valves are widely used in pressure measurement and control in industrial equipment, laboratory instruments, and aerospace fields. As a crucial input component of pressure scanning valves, the pressure tubing requires specialized tools for installation and removal to ensure safe and convenient operation. Pressure scanning valves are primarily used for high-precision pressure measurement, such as wind tunnel testing and engine test bench data acquisition. The insertion and removal pliers, as supporting tools, address the limitations of traditional methods and the need for improvements in existing technologies. Pressure scanning valves require multi-channel synchronous pressure measurement with high accuracy requirements and operate in complex environments, such as high temperatures and vibrations. Traditional manual insertion and removal of pressure tubing can be inconvenient, prone to damaging interfaces, and inefficient. Currently, commonly used methods include the following:

[0003] 1. General tool operation: Common general tools such as wrenches and pliers are generally used. This method has problems such as easy damage to pressure pipes and pressure scanning valve input interfaces, inconsistent force at each interface, inability to guarantee airtightness, inconvenient installation or disassembly, and low efficiency.

[0004] 2. Simple special tool operation: Common and universal simple plug-in tools are generally used. These tools are generally simple, not durable, and lack protective design. Using this method has problems such as poor tool compatibility and inability to guarantee the quality of installation and disassembly.

[0005] 3. Manual operation: This involves directly installing or removing pressure pipes by hand. This method has problems such as poor safety, easy damage to equipment, and low efficiency. Utility Model Content

[0006] In view of the deficiencies of the prior art, this utility model provides a pressure scanning valve pressure tube insertion and removal pliers, which can ensure the safe and convenient insertion and removal of pressure tubes, while protecting the pressure tube and the pressure scanning valve input interface from damage. It is also applicable to two different diameter pressure tubes and has a wide range of applications.

[0007] To achieve the above objectives, the present invention provides a pressure scanning valve pressure tube insertion and removal clamp, comprising a first clamp arm and a second clamp arm rotatably connected to the first clamp arm. The first clamp arm and the second clamp arm have an open state and a closed state. One end of the first clamp arm is provided with a first clamping mouth portion, which includes a first receiving groove and a second receiving groove that are parallel to each other. One end of the second clamp arm is provided with a second clamping mouth portion, which includes a third receiving groove and a fourth receiving groove that are parallel to each other. When in the closed state, the first receiving groove and the third receiving groove are connected to form a first anti-disengagement interface, and the second receiving groove and the fourth receiving groove are connected to form a second anti-disengagement interface.

[0008] Furthermore, the diameter of the first anti-detachment interface is 0.098 inches; the diameter of the second anti-detachment interface is 0.063 inches.

[0009] Furthermore, the inner sides of the first, second, third, and fourth receiving grooves are all provided with anti-slip textures.

[0010] Furthermore, a first clamping surface is provided between the first receiving groove and the second receiving groove, and the first clamping surface is provided with anti-slip texture. A second clamping surface is provided between the third receiving groove and the fourth receiving groove, and the second clamping surface is provided with anti-slip texture.

[0011] Furthermore, the first clamp arm and the second clamp arm are rotatably connected by a connecting buckle. A first shearing part is provided between the position where the first clamp arm is connected to the connecting buckle and the first clamp jaw, and a second shearing part is provided between the position where the second clamp arm is connected to the connecting buckle and the second clamp jaw.

[0012] Furthermore, a first arc-shaped recess is provided between the first shearing part and the first jaw part, and the first arc-shaped recess is provided with anti-slip texture; a second arc-shaped recess is provided between the second shearing part and the second jaw part, and the second arc-shaped recess is provided with anti-slip texture.

[0013] Furthermore, a spring is provided between the first clamp arm and the second clamp arm, the spring being used to provide a restoring force when the first clamp arm and the second clamp arm switch from the closed state to the open state.

[0014] Furthermore, the first clamp arm is rotatably connected to a locking hook, and the second clamp arm has a locking groove that cooperates with the locking hook.

[0015] Furthermore, a first handle portion is provided at the end of the first clamp arm away from the first clamp jaw portion, and the first handle portion is at least partially covered with anti-slip rubber; a second handle portion is provided at the end of the second clamp arm away from the second clamp jaw portion, and the second handle portion is at least partially covered with anti-slip rubber.

[0016] The beneficial effects of this utility model are:

[0017] First, this invention ensures sealing and measurement accuracy: the sealing of the pressure tube connection directly affects the accuracy of pressure signal transmission. The insertion and removal pliers of this invention have a uniform force application function, which can avoid loosening of the connection due to uneven force caused by manual operation or other non-special tools, thereby reducing the risk of leakage and maintaining the high-precision measurement performance of the pressure scanning valve.

[0018] Secondly, this invention can improve operational efficiency and safety: the pressure tube of the pressure scanning valve needs to be connected or replaced frequently (especially in multi-point measurement scenarios). The insertion and removal pliers of this invention, through optimized jaw design, enable quick insertion and removal of the pressure tube, reducing manual operation time, while avoiding pipeline deformation or interface damage caused by improper operation, and ensuring the long-term stability of the equipment.

[0019] Furthermore, this invention is adaptable to two different diameter pressure tubes: the first and second jaws on both sides of the pressure scanning valve pressure tube insertion and removal pliers form the jaw section, which is the front part of the tool and functions to clamp, position, guide, and protect the pressure tube during insertion and removal. The jaws on both sides have two standard-diameter, openable anti-disengagement interfaces, namely the first and second anti-disengagement interfaces, making it suitable for two different diameter pressure tubes and thus having a wide range of applications.

[0020] Finally, this invention can extend the service life of pressure scanning valves: through standardized operation using specialized tools, mechanical damage to the pressure scanning valve input interface caused by improper insertion and removal can be effectively reduced, maintenance costs can be lowered, and the service life of the pressure scanning valve and pressure pipe can be extended. At the same time, the insertion and removal pliers of this invention can also be used in various similar scenarios and play a role in protecting related equipment. Attached Figure Description

[0034] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0035] See Figures 1-2The diagram shows a structural schematic of a pressure scanning valve pressure tube insertion and removal pliers according to an embodiment of the present invention. This pliers can be applied in industrial equipment, laboratory instruments, and aerospace fields, specifically for installing and removing pressure tubes from pressure scanning valves. The pressure scanning valve pressure tube insertion and removal pliers include a first clamping arm 100 and a second clamping arm 200 rotatably connected to the first clamping arm 100. The first clamping arm 100 and the second clamping arm 200 have open and closed states. Figure 1 The diagram shown is a structural schematic of the pressure scanning valve when the pressure tube insertion / removal clamp is in the closed state. Figure 2 The diagram shows the structure of the pressure scanning valve pressure tube insertion / removal clamp in the open state.

[0036] See also Figures 4-6 One end of the first clamp arm 100 is provided with a first clamping jaw portion 110, which includes a first receiving groove 111 and a second receiving groove 112 that are parallel to each other; one end of the second clamp arm 200 is provided with a second clamping jaw portion 210, which includes a third receiving groove 211 and a fourth receiving groove 212 that are parallel to each other; when in the closed state, the first receiving groove 111 and the third receiving groove 211 are joined to form a first anti-detachment interface 300, and the second receiving groove 112 and the fourth receiving groove 212 are joined to form a second anti-detachment interface 400.

[0037] The first jaw portion 110 and the second jaw portion 210 on both sides of the aforementioned pressure scanning valve pressure tube insertion and removal pliers form the jaw portion, which is the front part of the tool. Its function is to clamp, position, guide, and protect the pressure tube during insertion and removal. The jaw portions on both sides have two standard diameter, openable anti-disengagement interfaces, a first anti-disengagement interface 300 and a second anti-disengagement interface 400, suitable for pressure tubes of two different diameters. The anti-disengagement interfaces of the jaws are designed as arc-shaped grooves (U-shaped), namely, the first receiving groove 111 and the second receiving groove 112, and the third receiving groove 211 and the fourth receiving groove 212, which are parallel to each other and have a clamping function, firmly clamping the pressure tube to be inserted or removed. This ensures that the pressure tube will not slip during insertion and removal, maintaining stability. When the jaws insert or remove the pressure tube from the pressure scanning valve input interface, the anti-disengagement interfaces help to accurately position and guide it. By precisely controlling the position of the jaw anti-disengagement interfaces, the pressure tube can be effectively aligned with the pressure scanning valve input interface, thus smoothly completing the insertion and removal action. It should be noted that the clamp jaws are suitable for pressure tubes made of PA, PU, ​​latex, and other materials. These materials possess certain elasticity, wear resistance, and pressure resistance, reducing wear and damage to interface components during insertion and removal, thus protecting the input interface of the pressure scanning valve. The aforementioned pressure scanning valve pressure tube insertion and removal pliers can adapt to various complex operating conditions: due to the numerous applications of pressure scanning valves (such as wind tunnel testing and aero-engine test bench testing), the pliers may need to withstand high temperatures, high pressures, or confined spaces. Appropriate dimensions, special materials, and adjustable jaw design enhance the tool's environmental adaptability, ensuring reliable operation even under extreme conditions.

[0038] Furthermore, in one embodiment, the first anti-detachment port 300 has a diameter of 0.098 inches; the second anti-detachment port 400 has a diameter of 0.063 inches, which can be used for pressure tubes of two different diameters.

[0039] In one embodiment, the inner sides of the first receiving groove 111, the second receiving groove 112, the third receiving groove 211, and the fourth receiving groove 212 are all provided with anti-slip textures 1111, 1121, 2111, and 2121. Specifically, the anti-slip textures 1111, 1121, 2111, and 2121 can be set as anti-slip fine threads, which can ensure that their surfaces are in close contact with the pressure tube, preventing slippage and damage to the pressure tube and the pressure scanning valve input interface.

[0040] In one embodiment, a first clamping surface 113 is provided between the first receiving groove 111 and the second receiving groove 112, and the first clamping surface 113 is provided with anti-slip texture 1131. A second clamping surface 213 is provided between the third receiving groove 211 and the fourth receiving groove 212, and the second clamping surface 213 is provided with anti-slip texture 2131.

[0041] In one embodiment, the first clamp arm 100 and the second clamp arm 200 are rotatably connected by a connecting buckle 500. A first shearing part 120 is provided between the position where the first clamp arm 100 is connected to the connecting buckle 500 and the first clamping jaw 110, and a second shearing part 220 is provided between the position where the second clamp arm 200 is connected to the connecting buckle 500 and the second clamping jaw 210. In this embodiment, the first shearing part 120 and the second shearing part 220 on both sides form a shearing opening. The shearing opening is one of the auxiliary functions of the pressure scanning valve pressure tube insertion and removal pliers. It can quickly and safely cut pressure tubes made of materials such as PA, PU, ​​and latex, forming a neat and smooth cut, which facilitates the insertion and removal of the pressure tube and improves the airtightness of the connection between the pressure tube and the pressure scanning valve input port.

[0042] In one embodiment, a first arc-shaped recess 130 is provided between the first shearing part 120 and the first jaw part 110, and the first arc-shaped recess 130 is provided with anti-slip texture 131. A second arc-shaped recess 230 is provided between the second shearing part 220 and the second jaw part 210, and the second arc-shaped recess 230 is provided with anti-slip texture 231. In this embodiment, the first arc-shaped recess 130 and the second arc-shaped recess 230 form a pressure tube straightening part, which is one of the auxiliary functions of the pressure scanning valve pressure tube insertion and removal pliers. It can straighten and straighten the head of pressure tubes made of PA, PU, ​​latex and other materials, so that the jaws can easily grip the pressure tube.

[0043] like Figure 3 As shown, in one embodiment, a spring 600 is provided between the first clamp arm 100 and the second clamp arm 200. The spring 600 provides a restoring force when the first clamp arm 100 and the second clamp arm 200 switch from a closed state to an open state. In this embodiment, the spring 600 is located inside the clamp body. When the operator releases the handle, the spring, through its own elastic restoring force, causes the jaws to automatically spring back and release the clamped pressure tube. This restoring force makes operation more convenient and faster, especially in frequent insertion and removal operations, saving a lot of time and effort.

[0044] In one embodiment, a locking hook 140 is rotatably connected to the first clamp arm 100, and a locking groove 240 is provided on the second clamp arm 200 to cooperate with the locking hook 140. The locking hook 140 and the locking groove 240 form a locking mechanism, which is one of the auxiliary functions of the pressure scanning valve pressure tube insertion and removal pliers. It is located inside the clamp body and consists of a rotatable locking hook 140 on one arm and a locking groove 240 on the other arm. When the tool needs to be closed, the locking hook 140 can be rotated into the locking groove 240, and the spring force can be used to lock the tool in a closed state for easy storage.

[0045] In one embodiment, a first handle portion 150 is provided at the end of the first clamp arm 100 away from the first jaw portion 110, and the first handle portion 150 is at least partially covered with anti-slip rubber 151; a second handle portion 250 is provided at the end of the second clamp arm 200 away from the second jaw portion 210, and the second handle portion 250 is at least partially covered with anti-slip rubber 251. The anti-slip rubber covering the surface facilitates gripping and application of force. The materials of the anti-slip rubber 151 and anti-slip rubber 251 provide a comfortable grip experience and reduce operator fatigue; at the same time, the anti-slip texture or particles on their surface ensure stable operation under high pressure.

[0046] The first handle portion 150 and the second handle portion 250 on both sides of the aforementioned pressure scanning valve pressure tube insertion and removal pliers constitute the handles of the pliers. These handles transmit the operator's applied force to the jaws through the lever effect of the pliers body, enabling them to firmly clamp or release the pressure tube. This force transmission mechanism ensures operational effectiveness, especially when greater operational force is required. Furthermore, the handles allow the operator to directly feel the feedback when the jaws contact the pressure tube, such as changes in resistance. This immediate feedback helps the operator adjust the operational force, angle, and method in a timely manner, thereby improving the overall accuracy of the insertion and removal operation. The handles are ergonomically designed to ensure operator comfort and convenience during prolonged use. Figure 1 and Figure 2 As shown, the shape, size, and surface texture of the handle are specially designed to better fit the contours of the hand and reduce fatigue.
