Description

Technical Field

[0001] This invention relates to the field of fixture technology, and more specifically to a measurement and control instrument. Background Technology

[0002] Currently, measurement and control instruments are a wide range of measuring instruments that utilize measurement and control theories, combining various metrological testing principles and control systems from mechanics, electronics, and optics with computers. To ensure measurement accuracy, these instruments need to be installed in different locations to obtain more data and improve measurement and control. Existing measurement and control instruments have relatively simple installation functions, typically bolted to flat or vertical surfaces. This does not adequately meet the needs of operators, requiring significant manual labor for installation and disassembly. Furthermore, once fixed, they lack the ability to adjust the measurement angle. When fixed to cylindrical installation spaces such as streetlights and steel pipes, loosening often occurs. Therefore, there is a lack of existing measurement and control instruments with centering and clamping capabilities that can be installed on tubular parts. Summary of the Invention

[0003] This invention relates to the field of fixing fixture technology, and more specifically to a measuring and control instrument. Its advantages are that it has a centering clamping function and can be installed on pipe parts, further ensuring the stable operation of the measuring and control instrument.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A measuring and control instrument includes a hollow tube and three sets of grippers that are uniformly fixed to the hollow tube in the circumferential direction. Each gripper includes two supports I, both of which are fixedly connected to the hollow tube. Support arms I are rotatably connected to each of the two supports I, and supports II are rotatably connected to each of the two support arms I. Arc-shaped grippers are fixedly connected to the two supports II, and the inner and outer sides of the arc-shaped grippers are both arc-shaped.

[0006] Furthermore, a sliding rod is slidably connected inside the hollow tube. The sliding rod has a cavity with an opening at the right end. A nut I is fixedly connected to the sliding rod. A screw I is threadedly connected to the nut I. A fixing ring is fixedly connected to the hollow tube. A U-shaped groove is provided on the fixing ring. A limiting groove I is provided on the screw I. The limiting groove I is rotatably connected in the U-shaped groove. The U-shaped groove and the limiting groove I are used to limit the screw I, so that the screw I cannot slide along the axis of the hollow tube. A knob I is fixedly connected to the screw I.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] The following is in conjunction with the appendix Figure 1-6Detailed description: A measurement and control instrument includes a hollow tube 101 and three sets of grippers. Each gripper includes a bracket I 102, a support arm I 103, a bracket II 104, and an arc-shaped gripper 105. Two brackets I 102 are fixedly connected to the hollow tube 101. Support arms I 103 are rotatably connected to both brackets I 102. Brackets II 104 are rotatably connected to both support arms I 103. Arc-shaped grippers 105 are fixedly connected to both brackets II 104. The inner and outer sides of the arc-shaped grippers 105 are both arc-shaped.

[0024] Furthermore, the hollow tube 101 is a hollow circular tube, providing sliding space for the sliding rod 106. The detection instrument contains three sets of grippers; here, one set of grippers is used as an example. A rotating shaft I is provided on the bracket I 102, and a shaft hole I is provided at the lower end of the support arm I 103. The rotating shaft I is rotatably connected in the shaft hole I, allowing the bracket I 102 to rotate around the hollow tube 101. A rotating shaft II is provided on the bracket II 104, and a shaft hole II is provided at the upper end of the support arm I 103. The rotating shaft II is rotatably connected in the shaft hole II, allowing the support arm I 103 to rotate around the arc-shaped gripper 105. The hollow tube 101, the two support arms I 103, and... The arc-shaped grippers 105 form a parallelogram structure, allowing the arc-shaped grippers 105 in the three sets of grippers to unfold concentrically relative to the hollow tube 101. Both the inner and outer sides of the arc-shaped grippers 105 are arc-shaped and have a fixing function. When it needs to be fixed inside the hole, the bracket I 102 rotates outward, causing the three arc-shaped grippers 105 to unfold away from the center. The outer sides of the three arc-shaped grippers 105 press against the inner wall of the hole to complete the fixation. When it needs to be fixed at one end of the cylinder, the bracket I 102 rotates inward, causing the three arc-shaped grippers 105 to retract towards the center. The inner sides of the three arc-shaped grippers 105 press against the side wall of the cylinder to complete the fixation.

[0025] The following is in conjunction with the appendix Figure 1-6 In detail, the measuring and control instrument also includes a sliding rod 106, a cavity 107, a nut I 108, a screw I 109, a retaining ring 110, a U-shaped groove 111, a limiting groove I 112, and a knob I 113. A sliding rod 106 is slidably connected inside the hollow tube 101. A cavity 107 with an opening at the right end is formed on the sliding rod 106. A nut I 108 is fixedly connected to the sliding rod 106, and a screw I 109 is threaded onto the nut I 108. 9. A fixing ring 110 is fixedly connected to the hollow tube 101. A U-shaped groove 111 is provided on the fixing ring 110. A limiting groove 112 is provided on the screw I 109. The limiting groove 112 is rotatably connected in the U-shaped groove 111. The U-shaped groove 111 and the limiting groove 112 are used to limit the screw I 109 so that the screw I 109 cannot slide along the axis of the hollow tube 101. A knob 113 is fixedly connected to the screw I 109.

[0026] Furthermore, cavity 107 provides rotation space for screw I 109. Nut I 108 has a threaded hole at its center, and nut I 108 is threadedly connected to screw I 109 through the threaded hole I. Limiting groove I 112 is rotatably connected in U-shaped groove 111. Fixing ring 110 is threadedly fixed to hollow tube 101. The U-shaped groove 111 on fixing ring 110 facilitates replacement of screw I 109 after wear. When knob I 113 is rotated clockwise, knob I 113 drives screw I 109 to rotate, and screw I 109 drives sliding rod 106 to move to the left through nut I 108, completing the extension of sliding rod 106. When knob I 113 is rotated counterclockwise, knob I 113 drives screw I 109 to rotate, and screw I 109 drives sliding rod 106 to move to the right through nut I 108, completing the retraction of sliding rod 106.

[0027] The following is in conjunction with the appendix Figure 1-6 In detail, the measuring and control instrument also includes bracket Ⅲ201, support arm Ⅱ202 and bracket Ⅳ203. Three brackets Ⅲ201 are circumferentially fixedly connected to the sliding rod 106. Each bracket Ⅲ201 is rotatably connected to a support arm Ⅱ202. Each support arm Ⅱ202 is rotatably connected to a bracket Ⅳ203. Each bracket Ⅳ203 is fixedly connected to an arc-shaped gripper 105 located on the same side.

[0028] Furthermore, a rotating shaft III is provided on bracket III 201, and a shaft hole III is provided at the lower end of support arm II 202. The rotating shaft III is rotatably connected in the shaft hole III, allowing support arm II 202 to rotate around sliding rod 106. A rotating shaft IV is provided on bracket IV 203, and a shaft hole IV is provided at the lower end of support arm II 202. The rotating shaft IV is rotatably connected in the shaft hole IV, allowing support arm II 202 to rotate around arc-shaped gripper 105. When the knob I 113 is rotated clockwise, the sliding rod 106 extends, and the sliding rod 106 pushes the arc-shaped gripper 105 to unfold away from the center through bracket III 201, support arm II 202, and bracket IV 203. When the knob I 113 is rotated counterclockwise, the sliding rod 106 extends, and the sliding rod 106 pushes the arc-shaped gripper 105 to retract towards the center through bracket III 201, support arm II 202, and bracket IV 203.

[0029] The following is in conjunction with the appendix Figure 1-6 In detail, the measuring and control instrument also includes a limiting rod 204 and a limiting groove II 205. The limiting rod 204 is fixedly connected to the hollow tube 101, and the limiting groove II 205 is opened on the sliding rod 106. The limiting rod 204 is slidably connected in the limiting groove II 205.

[0030] Furthermore, the limiting rod 204 and the limiting groove II 205 serve as limiting mechanisms. The limiting rod 204 is slidably connected in the limiting groove II 205 to limit the movement, so that the sliding rod 106 can only slide along the axis of the hollow tube 101 and cannot rotate in the hollow tube 101.

[0031] The following is in conjunction with the appendix Figure 7-11 In detail, the measuring and control instrument also includes a rotating base 301, a bracket V 302, a screw II 303, a screw head 304, and a nut II 305. The rotating base 301 is fixedly connected to both the front and rear sides of the hollow tube 101. The bracket V 302 is rotatably connected to the two rotating bases 301. The screw II 303 is rotatably connected to the rotating base 301. The screw head 304 is fixedly connected to the screw II 303. The screw head 304 is used to abut against the outside of the bracket V 302. The nut II 305 is threadedly connected to the screw II 303.

[0032] Furthermore, the rotating seat 301 provides support and rotation space for the bracket V 302. The rotating seat 301 has a rotating shaft V, and the bracket V 302 has a shaft hole V. The rotating shaft V is rotatably connected in the shaft hole V, allowing the bracket V 302 to rotate on the hollow tube 101. The bracket V 302 has a circular hole I, and a screw II 303 is rotatably connected in the circular hole I. The screw head 304 limits the movement of the screw II 303. After the detection instrument is fixed, the nut II 305 is loosened, allowing the bracket V 302 to rotate on the hollow tube 101, enabling angle adjustment of the detection instrument. After angle adjustment, the nut II 305 is tightened, clamping the bracket V 302 onto the rotating seat 301, preventing the bracket V 302 from rotating on the hollow tube 101, thus fixing the angle of the detection instrument.

[0033] The following is in conjunction with the appendix Figure 7-11 In detail, the measuring and control instrument also includes a rotating shaft 401 and a fixed frame 402. The rotating shaft 401 is rotatably connected to the bracket V302, and the fixed frame 402 is fixedly connected to the rotating shaft 401.

[0034] Furthermore, the lower end of the bracket V302 is provided with a shaft hole VI, and the rotating shaft 401 is rotatably connected in the shaft hole VI, so that the fixing frame 402 can rotate on the bracket V302, and the angle of the detection device can be adjusted by rotating the fixing frame 402.

[0035] The following is in conjunction with the appendix Figure 7-11In detail, the measuring and control instrument also includes a rotating seat I 403, a slide rail 404, a rotating seat II 405, and a hemispherical cavity 406. The rotating seat I 403 is fixedly connected to the fixed frame 402, the slide rail 404 is fixedly connected to the fixed frame 402, and the rotating seat II 405 is slidably connected to the slide rail 404. The slide rail 404 is used to ensure that the rotating seat II 405 can only slide along the axis of the slide rail 404. Both the rotating seat I 403 and the slide rail 404 are provided with hemispherical cavities 406.

[0036] Furthermore, the fixed frame 402 provides support and installation space for the slide rail 404. The slide rail 404 consists of two cylindrical slide rails. The rotating seat II 405 has two circular holes II. The slide rail 404 is slidably connected in the circular holes II, so that the rotating seat II 405 can slide along the axis of the slide rail 404.

[0037] The following is in conjunction with the appendix Figure 7-11 In detail, the measuring and control instrument also includes a screw III 407, a knob II 408, and a spring 409. The screw III 407 is rotatably connected to the rotating seat II 405. The screw III 407 is threadedly connected to the fixed frame 402. The knob II 408 is fixedly connected to the screw III 407. The spring 409 is slidably connected to the slide rail 404. The spring 409 is used to make the rotating seat II 405 tend to slide towards the rotating seat I 403.

[0038] Furthermore, the fixed frame 402 is provided with a threaded hole II, and the screw III 407 is threadedly connected to the fixed frame 402 through the threaded hole II. The spring 409 is provided to prevent the screw III 407 from rotating due to vibration, which would cause the fixation of the ball 410 to loosen.

[0039] The following is in conjunction with the appendix Figure 7-11 In detail, the measuring and control instrument also includes a sphere 410 and a support rod 411. The sphere 410 is rolled between the two hemispherical cavities 406, and the support rod 411 is fixedly connected to the lower end of the sphere 410.

[0040] Furthermore, when the detection device needs to work horizontally relative to the bottom surface, rotating the screw III 407 clockwise will move the two hemispherical cavities 406 on the rotating seats I 403 and II 405 away from each other, and allow the sphere 410 to rotate freely on the two hemispherical cavities 406. The measurement and control device 501 will rotate to a working state horizontal with the bottom surface by gravity. When the screw III 407 is rotated counterclockwise, the two hemispherical cavities 406 on the rotating seats I 403 and II 405 will move closer to each other and clamp the sphere 410, thus completing the fixation of the measurement and control device 501.

[0041] The following is in conjunction with the appendix Figure 11In detail, the measuring and control instrument also includes a measuring and control device 501 and a measuring and control probe 502.
