Description

Technical Field

[0001] This utility model relates to the field of communication equipment testing technology, and specifically to a testing fixture for communication equipment. Background Technology

[0002] Communication equipment refers to equipment used to realize communication functions, including wired communication equipment and wireless communication equipment. Wired communication equipment includes transmission equipment, switching equipment, and access equipment, while wireless communication equipment includes mobile terminal equipment, wireless network equipment, and short-range wireless communication equipment. During the production process, switching equipment needs to undergo quality inspection through testing devices. Testing of communication equipment is a key link to ensure the performance and quality of the equipment. It mainly includes functional testing, performance testing, compatibility testing, and security testing. Test fixtures are devices designed to ensure the stable position of communication equipment during the testing process. They can be fixed by clamping, squeezing, or pressing.

[0003] CN219244773U discloses a testing fixture for communication equipment, including a base, a platform, and an electronic scale. The base has a mounting groove on its top, in which a motor is fixedly installed. The platform is rotatably connected to the surface of the base, and the output end of the motor is fixedly connected to the bottom of the platform. The electronic scale is fixedly installed on the surface of the platform, and positioning plates are symmetrically arranged on both sides of the scale, with the positioning plates fixedly connected to the bottom of the platform. This invention allows for the weighing of communication equipment using an electronic scale, the measurement of its dimensions using a vertical and horizontal ruler, and the effective clamping of the communication equipment by the platform. Furthermore, the motor drives the platform to rotate, enabling multi-angle adjustment of the communication equipment and facilitating comprehensive testing by the user. It is highly practical.

[0004] While the existing technology CN219244773U has many advantages in use, it still has the following problems: its clamping of irregularly shaped parts is not perfect. Since most irregularly shaped communication devices have uneven surfaces, the single clamping method has poor fixation of the communication device, which affects the stability of the subsequent testing process of the communication device. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a testing fixture for communication equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is a testing fixture for communication equipment, including a placement platform, a liquid storage box, a piston rod, and a fixing plate. Both sides of the upper outer wall of the placement platform are screwed with baffle plates. The outer walls of the two baffle plates on opposite sides are provided with sliding grooves. A liquid storage box is provided on one side of the outer wall of the baffle plate. Fixing plates arranged in a rectangular array are installed on the upper outer wall of the placement platform. Screws are rotatably installed inside the fixing plates. Piston tubes that are equally spaced and parallel are inserted into the outer wall of the liquid storage box. A piston rod is provided inside the piston tube. A sealing ring is screwed to the outer wall of one end of the piston rod.

[0007] By adopting the above technical solution, the operator places the communication device to be tested on the upper part of the placement platform, between two baffles. The baffles prevent the testing device from moving on the placement platform, serving a positioning and protection function. By rotating the screw, the operator can synchronously drive the liquid storage box to move through the drive plate, causing the two liquid storage boxes to move towards or away from each other, thus adjusting the distance between the two liquid storage boxes until the clamping plate contacts the outer wall of the communication device through the protective pad. Through the multi-point arrangement of the clamping plate, the communication device can be clamped and fixed at multiple points. The position of the clamping plate can be adjusted through the piston rod and sealing ring, allowing the clamping position of the clamping plate at different positions to be adjusted. The multi-point clamping plate can clamp and fix communication devices of different shapes, ensuring the stability of the communication device and guaranteeing the stability of the communication device during subsequent testing, while also improving the versatility and adaptability of the equipment.

[0008] Specifically, sliders are installed on both outer walls of the liquid storage box. The outer wall of the slider and the inner wall of the groove are both rectangular in shape, and the slider is slidably installed inside the groove.

[0009] By adopting the above technical solution, the slider and the groove make the liquid storage box very stable after installation. At the same time, the liquid storage box can slide smoothly in the groove through the slider, which makes it easy to adjust the position of the liquid storage box according to the test requirements and ensure the distance between the liquid storage box and the communication equipment.

[0010] Specifically, a handle is screwed to one end of the screw that passes through the fixing plate, and a drive plate is screwed to both sides of the screw. The other end of the drive plate is screwed to the upper outer wall of the liquid storage box, and the threaded openings on the two sides of the screw are in opposite directions.

[0011] By adopting the above technical solution, the operator can manually rotate the screw through the handle. When the screw is rotated, since the thread openings on the outer walls on both sides of the screw are in opposite directions, the two drive plates can move in opposite or opposite directions at the same time. The drive plates can drive the liquid storage box to move synchronously, which can precisely control the translational movement of the liquid storage box, making it convenient to fix or disassemble the communication equipment.

[0012] Specifically, a flange is welded to one side of the outer wall of the piston tube, and the piston tube is connected to the outer wall of the liquid storage box through the flange. The sealing ring is in contact with the inner wall of the piston tube.

[0013] By adopting the above technical solution, the flange ensures the firmness of the connection between the piston tube and the liquid storage box, facilitates installation and disassembly, and ensures the sealing of the connection between the piston tube and the liquid storage box.

[0014] Specifically, a connecting pipe is welded to one side of the outer wall of the liquid storage box, and the connecting pipe is connected to the inside of the liquid storage box.

[0015] By adopting the above technical solution, the liquid storage box can be connected to the oil supply pipeline of the external hydraulic equipment through the connecting pipe. After ensuring that the clamping plates at multiple points are in contact with the outer wall of the communication equipment, the hydraulic equipment inputs hydraulic oil into the liquid storage box through the connecting pipe and maintains the pressure of the hydraulic oil. The hydraulic oil can flow into the piston tube through the through hole of the positioning sleeve, thereby supporting the sealing ring through the pressure of the hydraulic oil, ensuring the clamping force of the clamping plate on the communication equipment, and ensuring the stability of the communication equipment on the upper part of the placement platform.

[0016] Specifically, one end of the piston rod protrudes from the outer wall of the piston tube and is screwed to a clamping plate, and the other end of the clamping plate is glued and fixed with a protective pad.

[0017] By adopting the above technical solution, the clamping plate can be used to clamp communication equipment. The protective pads that are bonded and fixed to the clamping plate can prevent damage to the surface of the communication equipment during the clamping process, while increasing friction to make the clamping more stable.

[0018] Specifically, a positioning sleeve is threaded onto one side of the outer wall of the piston tube, and a through hole is provided inside the positioning sleeve. A support spring is provided inside the piston tube, and the outer walls of both ends of the support spring contact the inner wall of the positioning sleeve and the outer wall of the sealing ring, respectively. The sealing ring is elastically connected to the inner wall of the positioning sleeve through the support spring.

[0019] By adopting the above technical solution, the positioning sleeve can position and fix the support spring, and the elastic force of the support spring can support the position of the sealing ring, ensuring the initial position of the clamping plate is stable and ensuring that the position of the clamping plate can be reset in the future.

[0020] The beneficial effects of this utility model are:

[0021] (1) The testing fixture for communication equipment described in this utility model has adjustable clamping positions of clamping plates at different locations. Through the multi-point clamping plates, communication equipment of different shapes can be clamped and fixed, ensuring the stability of the communication equipment and guaranteeing the stability of the communication equipment during subsequent testing. It also improves the versatility and adaptability of the equipment.

[0022] (2) In the test fixture for communication equipment described in this utility model, after the clamping plates are in contact with the outer wall of the communication equipment, the hydraulic equipment inputs hydraulic oil into the reservoir box through the connecting pipe and maintains the pressure of the hydraulic oil. The hydraulic oil can flow into the piston tube through the through hole of the positioning sleeve, so that the pressure of the hydraulic oil can support the sealing ring, ensure the clamping force of the clamping plate on the communication equipment, and ensure the stability of the communication equipment on the upper part of the placement platform.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the testing fixture for a communication device according to this utility model includes a placement platform 1, a liquid storage box 2, a piston rod 3, and a fixing plate 4. Both sides of the upper outer wall of the placement platform 1 are screwed with baffle plates 11. The outer walls of the two baffle plates 11 on opposite sides are provided with sliding grooves 12. A liquid storage box 2 is provided on one side of the outer wall of the baffle plate 11. A fixing plate 4 with a rectangular array is installed on the upper outer wall of the placement platform 1. A screw 41 is rotatably installed inside the fixing plate 4. A piston tube 23 with equal and parallel distribution is inserted into the outer wall of the liquid storage box 2. A piston rod 3 is provided inside the piston tube 23. A sealing ring 31 is screwed to the outer wall of one end of the piston rod 3.

[0032] During use, the operator places the communication device to be tested on the upper part of the placement platform 1, between the two baffle plates 11. The baffle plates 11 prevent the testing device from moving on the placement platform 1, serving a positioning and protection function. By rotating the screw 41, the operator can synchronously drive the liquid storage box 2 to move through the drive plate 43, causing the two liquid storage boxes 2 to move towards or away from each other, thus adjusting the distance between the two liquid storage boxes 2 until the clamping plate 32 contacts the outer wall of the communication device through the protective pad 33. Through the multi-point arrangement of the clamping plate 32, the communication device can be clamped and fixed at multiple points. The clamping plate 32 can be adjusted in position through the piston rod 3 and the sealing ring 31, allowing the clamping position of the clamping plate 32 at different positions to be adjusted. The multi-point clamping plate 32 can clamp and fix communication devices of different shapes, ensuring the stability of the communication device and guaranteeing the stability of the communication device during subsequent testing, while also improving the versatility and adaptability of the equipment.

[0033] To limit the movement trajectory, for example, such as Figure 2 As shown, sliders 22 are installed on both outer walls of the liquid storage box 2. The outer wall of slider 22 and the inner wall of slide groove 12 are both rectangular in shape. Slider 22 is slidably installed inside slide groove 12.

[0034] During use, the slider 22 and the slide groove 12 make the liquid storage box 2 very stable after installation. At the same time, the liquid storage box 2 can slide smoothly in the slide groove 12 through the slider 22, which makes it easy to adjust the position of the liquid storage box 2 according to the test requirements and ensure the distance between the liquid storage box 2 and the communication equipment.

[0035] To drive movement, for example, such as Figure 5 As shown, the screw 41 passes through the outer wall of the fixing plate 4 and is screwed to a handle 42. Both sides of the outer wall of the screw 41 are screwed to drive plates 43. The other end of the drive plate 43 is screwed to the upper outer wall of the liquid storage box 2. The threaded openings on the outer walls of the two sides of the screw 41 are in opposite directions.

[0036] In use, the operator can manually rotate the screw 41 through the handle 42. When the screw 41 is rotated, since the thread openings on the outer walls of the two sides of the screw 41 are in opposite directions, the two drive plates 43 can move in opposite or opposite directions at the same time. The drive plates 43 can drive the liquid storage box 2 to move synchronously, which can precisely control the translational movement of the liquid storage box 2, making it convenient to fix or disassemble the communication equipment.

[0037] For the purpose of ensuring a tight seal, exemplarily, such as... Figure 3 As shown, a flange 24 is welded to one side of the outer wall of the piston tube 23, and the piston tube 23 is connected to the outer wall of the liquid storage box 2 through the flange 24. The sealing ring 31 is in contact with the inner wall of the piston tube 23.

[0038] During use, flange 24 ensures the firmness of the connection between piston tube 23 and liquid storage box 2, facilitates installation and disassembly, and ensures the sealing of the connection between piston tube 23 and liquid storage box 2.

[0039] To input hydraulic fluid, for example, such as Figure 2 As shown, a connecting pipe 21 is welded to one side of the outer wall of the liquid storage box 2, and the connecting pipe 21 is connected to the inside of the liquid storage box 2.

[0040] In use, the liquid storage box 2 can be connected to the oil supply line of the external hydraulic equipment through the connecting pipe 21. After ensuring that the clamping plates 32 at multiple points are in contact with the outer wall of the communication equipment, the hydraulic equipment inputs hydraulic oil into the liquid storage box 2 through the connecting pipe 21 and maintains the pressure of the hydraulic oil. The hydraulic oil can flow into the piston tube 23 through the through hole of the positioning sleeve 25, so that the pressure of the hydraulic oil can support the sealing ring 31, ensure the clamping force of the clamping plate 32 on the communication equipment, and ensure the stability of the communication equipment on the upper end of the placement platform 1.

[0041] For clamping communication devices, exemplarily, such as Figure 3 As shown, one end of the piston rod 3 protrudes from the outer wall of the piston tube 23 and is screwed to a clamping plate 32. The other end of the clamping plate 32 is glued and fixed with a protective pad 33.

[0042] In use, the clamping plate 32 can be used to clamp communication equipment. The protective pad 33, which is bonded and fixed on the clamping plate 32, can prevent damage to the surface of the communication equipment during the clamping process, while increasing friction to make the clamping more stable.

[0043] To maintain the usage location, for example, such as Figure 3 As shown, a positioning sleeve 25 is threadedly connected to one side of the outer wall of the piston tube 23. The positioning sleeve 25 has a through hole inside. A support spring 26 is installed inside the piston tube 23. The outer walls of both ends of the support spring 26 are in contact with the inner wall of the positioning sleeve 25 and the outer wall of the sealing ring 31, respectively. The sealing ring 31 is elastically connected to the inner wall of the positioning sleeve 25 through the support spring 26.

[0044] In use, the positioning sleeve 25 can position and fix the support spring 26, and the elastic force of the support spring 26 can support the position of the sealing ring 31, ensuring the initial position of the clamping plate 32 is stable and ensuring that the position of the clamping plate 32 can be reset in the future.

[0045] When using this utility model, the operator places the communication device to be tested on the upper part of the placement platform 1, positioning it between the two baffle plates 11. The baffle plates 11 are used to achieve initial positioning and protection of the communication device. The operator rotates the handle 42 at one end of the screw 41. Since the thread openings on the outer walls of the two sides of the screw 41 are in opposite directions, the two drive plates 43 are driven to move simultaneously in opposite or opposite directions. This drives the liquid storage box 2 to move horizontally on the placement platform 1 with the cooperation of the slider 22 and the slide groove 12, adjusting the distance between the two liquid storage boxes 2 until the clamping plate 32 is close to the communication device.

[0046] During the movement of the liquid storage box 2, the clamping plates 32, which are arranged at multiple points, gradually approach the communication device. The multi-point arrangement can adapt to communication devices of different shapes. When the clamping plates 32 come into contact with the outer wall of the communication device through the protective pads 33, they achieve multi-point compression of the communication device.

[0047] After confirming that all clamping plates 32 are in contact with the outer wall of the communication equipment, the hydraulic equipment inputs hydraulic oil into the reservoir 2 through the connecting pipe 21 and maintains the pressure of the hydraulic oil inside the reservoir 2. The pressure of the hydraulic oil acts on the sealing ring 31 to support it, thereby enhancing the clamping force of the clamping plates 32 on the communication equipment and ensuring the stability of the communication equipment on the upper end of the placement platform 1.

[0048] After the test, the staff flipped the handle 42 to move the liquid storage box 2 away from the communication equipment and removed the communication equipment. The hydraulic equipment was depressurized, and the elastic force of the support spring 26 pushed the sealing ring 31 out of position, so that the clamping plate 32 was reset and ready for the next test.

[0049] It should be noted that this utility model is a testing fixture for communication equipment. All components in this utility model are known to those skilled in the art, and their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
