Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment maintenance, and specifically relates to a workbench for endoscope maintenance. Background Art

[0002] Endoscopes may be damaged during long-term use, such as blurred mirror shooting angles, superfluous footage, severe wear of steel wires and spiral tubes, and display errors on the display screen. When the endoscope display screen displays errors or goes black, the entire device needs to be disassembled and the circuit lines of the internal integrated board checked to see if there are any disconnections. If there are any disconnections, new solder joints need to be re-soldered on the integrated board to repair the disconnections.

[0003] However, when welding the existing integrated board, the maintenance workers usually directly place the integrated board on the maintenance table for welding. In this way, the welded integrated board is not fixed. When the welding head accidentally touches the integrated board or the integrated board is pressed during welding, the welding of the integrated board may become unstable and displaced.

[0004] In the prior art, the application number is CN202211148962.2, and the name is a maintenance device for a medical endoscope. A maintenance device for a medical endoscope is disclosed, including a workbench, a maintenance table is fixedly installed at the middle of the upper end of the workbench, and an adjustment device is arranged inside the workbench, and the adjustment device includes a bidirectional threaded rod, a rotating shaft, a turntable and a threaded cylinder.

[0005] Although the above patent can clamp and fasten the integrated small board through the clamping device to facilitate maintenance workers to carry out maintenance, the adjustment accuracy of the clamping plate is low, and the clamping plate can only be roughly adjusted, so that the clamping plate may cause damage to the integrated small board. In view of this, the present utility model is specially proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a workbench for endoscope maintenance that can overcome the above problems or at least partially solve the above problems.

[0007] To solve the above technical problems, the basic concept of the technical solution adopted by the present utility model is as follows: A workbench for endoscope maintenance, comprising: a maintenance table, a groove is provided on the maintenance table, and legs are fixedly connected to the four corners at the bottom of the maintenance table; a bidirectional lead screw, rotatably connected in the groove; first T-shaped blocks, symmetrically arranged in the groove and threadedly connected to the bidirectional lead screw; moving blocks, symmetrically slidably connected to the maintenance table, and the two moving blocks are respectively fixedly connected to the first T-shaped blocks on the same side, a rectangular through groove is transversely provided in the moving block; a threaded rod, moving in the rectangular through groove; a rectangular rod, slidably connected in the rectangular through groove and fixedly connected to the threaded rod, the rectangular rod is arranged at one end adjacent to the two threaded rods; a clamping plate, installed at the end of the rectangular rod away from the threaded rod; a toothed ring, rotatably arranged in the moving block and threadedly connected to the threaded rod; a rotating rod, rotatably connected to the moving block; a gear, fixedly connected to the end of the rotating rod and meshed with the toothed ring, and the diameter of the toothed ring is greater than the diameter of the gear.

[0008] In order to facilitate real-time monitoring of the clamping force of the clamping plate on the integrated circuit board, further, a pressure sensor is fixedly connected between the rectangular rod and the clamping plate.

[0009] In order to prevent the clamping plate from tilting, further, guide rods are symmetrically and slidably connected to both sides of the rectangular rod in the moving block, and the end of the guide rod close to the pressure sensor is fixedly connected to the clamping plate.

[0010] In order to facilitate improving the protection effect on the integrated circuit board, further, rubber pads are fixedly connected to the adjacent surfaces of the two clamping plates.

[0011] In order to reduce the friction between the toothed ring and the moving block, further, an installation groove perpendicular to the rectangular groove is provided on the moving block, the toothed ring is located in the installation groove, the width of the installation groove is greater than the thickness of the toothed ring, and two groups of second T-shaped blocks are symmetrically and fixedly connected to the inner wall of the installation groove, and T-shaped grooves for cooperating with the second T-shaped blocks are provided on the toothed ring.

[0012] In order to facilitate improving the stability of the workbench, further, an open cavity is provided at the lower end of the leg, and the open cavities on multiple legs communicate with each other through a connecting air pipe. An air extraction pipe is installed on one of the legs, and the air extraction pipe is connected to the adjacent open cavity, and a rubber ring is fixedly connected to the lower end of the leg.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art: By the combined use of components such as a bidirectional lead screw, a first T-shaped block, a moving block, a threaded rod, a rectangular rod, a toothed ring, a gear, and a rotating rod, when controlling the two clamping plates to approach each other to clamp and fix the integrated circuit board, the distance between the two clamping plates can be roughly adjusted first. When the clamping plate is about to contact the integrated circuit board, the distance between the clamping plates is then finely adjusted. Compared with the prior art method of directly adjusting the distance between the two clamping plates, it can not only ensure the clamping and fixing effect on the integrated circuit board, but also make the clamping plate approach and contact the integrated circuit board slowly, avoiding the clamping plate from scratching the integrated circuit board, and effectively ensuring the protection effect on the integrated circuit board.

DETAILED DESCRIPTION OF THE INVENTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0023] Embodiment 1:

[0024] Referring to Figures 1 - 5 , a workbench for endoscope maintenance, comprising: a maintenance table 1, a groove 101 is provided on the maintenance table 1, and legs 102 are fixedly connected to the four corners at the bottom of the maintenance table 1; a bidirectional lead screw 2, rotatably connected in the groove 101; first T-shaped blocks 201, symmetrically arranged in the groove 101 and threadedly connected to the bidirectional lead screw 2; moving blocks 3, symmetrically and slidably connected to the maintenance table 1, and the two moving blocks 3 are respectively fixedly connected to the first T-shaped blocks 201 on the same side. A rectangular through groove is transversely provided in the moving block 3; a threaded rod 301, moving in the rectangular through groove; a rectangular rod 302, slidably connected in the rectangular through groove and fixedly connected to the threaded rod 301, and the rectangular rod 302 is arranged at one end adjacent to the two threaded rods 301; a clamping plate 304, installed at the end of the rectangular rod 302 away from the threaded rod 301; a toothed ring 306, rotatably arranged in the moving block 3 and threadedly connected to the threaded rod 301; a rotating rod 308, rotatably connected to the moving block 3; a gear 307, fixedly connected to the end of the rotating rod 308 and meshing with the toothed ring 306, and the diameter of the toothed ring 306 is greater than the diameter of the gear 307.

[0025] When the integrated circuit board in the endoscope needs to be repaired, the maintenance personnel first place the repair table 1 on the desktop through the legs 102, and then place the integrated circuit board to be repaired at the position between the two clamping plates 304 on the repair table 1. Then, the bidirectional lead screw 2 can be rotated by controlling the rotating wheel at one end of the bidirectional lead screw 2. Then, the bidirectional lead screw 2 can control the two moving blocks 3 to approach each other through the first T-shaped block 201. When the two moving blocks 3 drive the two clamping plates 304 to be about to contact the two sides of the integrated circuit board, the rotation of the bidirectional lead screw 2 can be stopped at this time. Then, the rotating rod 308 can be rotated by rotating the handwheel at one end of the rotating rod 308, and the rotating rod 308 will drive the gear 307 to rotate. Since the diameter of the gear 307 is smaller than the diameter of the gear ring 306, the diameter of the gear ring 306 can be set to be greater than four times the diameter of the gear 307. Therefore, when the gear 307 drives the gear ring 306 to rotate, the maintenance personnel need to rotate the gear 307 four times to drive the gear ring 306 to rotate one circle. Thus, the position of the threaded rod 301 can be finely adjusted through the gear ring 306, and the threaded rod 301 will drive the clamping plate 304 to adjust the position through the rectangular rod 302. When the clamping plate 304 is closely attached to the side of the integrated circuit board, the clamping and fixing of the integrated circuit board can be completed at this time. Finally, the maintenance personnel can perform repair operations on the integrated circuit board. Through the coordinated use of components such as the bidirectional lead screw 2, the first T-shaped block 201, the moving block 3, the threaded rod 301, the rectangular rod 302, the gear ring 306, the gear 307, and the rotating rod 308, when controlling the two clamping plates 304 to approach each other to clamp and fix the integrated circuit board, the distance between the two clamping plates 304 can be roughly adjusted first. When the clamping plate 304 is about to contact the integrated circuit board, the distance between the clamping plates 304 is finely adjusted at this time. Compared with the existing method of directly adjusting the distance between the two clamping plates 304, it can not only ensure the clamping and fixing effect of the integrated circuit board, but also make the clamping plate 304 slowly approach and contact the integrated circuit board, avoiding the clamping plate 304 from clamping and damaging the integrated circuit board, and effectively ensuring the protection effect on the integrated circuit board.

[0026] Embodiment 2:

[0027] Referring to Figures 1 - 5 , a workbench for endoscope repair, which is basically the same as Embodiment 1. Further: A pressure sensor 303 is fixedly connected between the rectangular rod 302 and the clamping plate 304. Through the setting of the pressure sensor 303, the clamping force of the clamping plate 304 on the integrated circuit board can be monitored in real time, so as to facilitate ensuring that the clamping force of the clamping plate 304 on the integrated circuit board is within the specified range, and effectively improving the protection effect on the integrated circuit board.

[0028] On both sides of the rectangular rod 302 inside the moving block 3, guide rods 3010 are symmetrically and slidably connected. One end of the guide rod 3010 close to the pressure sensor 303 is fixedly connected to the clamping plate 304. Through the arrangement of the guide rod 3010, not only can the inclination of the clamping plate 304 be avoided, reducing the contact area between the clamping plate 304 and the integrated circuit board, but also the accuracy of the pressure detection by the pressure sensor 303 can be ensured.

[0029] On the adjacent surfaces of the two clamping plates 304, rubber pads 305 are fixedly connected. Through the arrangement of the rubber pads 305, the rigid contact between the clamping plate 304 and the integrated circuit board can be converted into a flexible contact, thereby improving the protection effect on the integrated circuit board and preventing the clamping plate 304 from clamping the integrated circuit board damaged.

[0030] Embodiment 3:

[0031] Refer to Figures 1 - 5 , a workbench for endoscope maintenance, which is basically the same as Embodiment 2. Further: an installation groove perpendicular to the rectangular groove is formed on the moving block 3. The toothed ring 306 is located in the installation groove. The width of the installation groove is greater than the thickness of the toothed ring 306. Two groups of second T-shaped blocks 309 are symmetrically and fixedly connected to the inner wall of the installation groove. T-shaped grooves for cooperating with the second T-shaped blocks 309 are formed on the toothed ring 306. By rotating the toothed ring 306 in the installation groove through the second T-shaped blocks 309, the friction between the toothed ring 306 and the moving block 3 can be reduced, so that the maintenance personnel can more conveniently control the movement of the threaded rod 301.

[0032] An opening cavity 103 is formed at the lower end of the leg 102. The opening cavities 103 on multiple legs 102 are mutually communicated through connecting air pipes. An air extraction pipe is installed on one of the legs 102, and the air extraction pipe is communicated with the adjacent opening cavity 103. A rubber ring 104 is fixedly connected to the lower end of the leg 102. When the maintenance personnel place the maintenance table 1 on the desktop through the legs 102, the air extraction pipe can be connected to an external suction pump at this time, and then the four opening cavities 103 can be evacuated under the cooperation of the four connecting air pipes. Then, under the cooperation of the rubber ring 104, negative pressure can be drawn between the opening cavity 103 and the desktop, and then the leg 102 can be stably adsorbed and fixed on the desktop under the action of the negative pressure, effectively improving the stability of the workbench.

[0033] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
