[0030] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0031] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Persons skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0033] Embodiment 1, referring to Figure 3 , is the first embodiment of the present invention. This embodiment provides a telescopic rod mechanism that can achieve the effect of automatically adjusting the extended distance of the telescopic rod.

[0034] It includes a driving component 100, and the driving component 100 provides power for the movement of the telescopic component 200.

[0035] Specifically, the driving component 100 includes a driving shaft 102. One end of the driving shaft 102 is fixedly connected to a hand crank 101. Rotating the hand crank 101 can drive the driving shaft 102 to rotate. It also includes a driven shaft 104. The driven shaft 104 is arranged as a screw rod. A moving part 105 is arranged on the driven shaft 104. The moving part 105 is arranged as a nut. When the driven shaft 104 rotates, the moving part 105 can reciprocate along the axial direction of the driven shaft 104. A transmission belt 103 is sleeved on the driving shaft 102 and the driven shaft 104, and the transmission belt 103 drives the driven shaft 104 to rotate synchronously with the driving shaft 102.

[0036] The telescopic component 200 includes a first support rod 201 and a second support rod 202. A telescopic rod assembly 204 is movably arranged between the first support rod 201 and the second support rod 202. The second support rod 202 can move in a direction closer to or farther away from the first support rod 201 under the drive of the telescopic rod assembly 204.

[0037] Specifically, the telescopic rod assembly 204 includes a first connecting rod 204a. A second connecting rod 204b is hinged to the first connecting rod 204a through a pin shaft. The first connecting rod 204a and the second connecting rod 204b are arranged in a cross manner. The hinge point is arranged at the middle position between the first connecting rod 204a and the second connecting rod 204b. The first connecting rod 204a and the second connecting rod 204b can rotate relative to the hinge point with respect to each other.

[0038] Further, several pairs of the first connecting rod 204a and the second connecting rod 204b are provided. Each pair of the first connecting rod 204a and the second connecting rod 204b is linearly arranged and hinged at the opposite ends. For example, the rear end of the first connecting rod 204a of the first pair is hinged to the front end of the second connecting rod 204b of the second pair, the rear end of the second connecting rod 204b of the second pair is hinged to the front end of the first connecting rod 204a of the third pair, the rear end of the first connecting rod 204a of the third pair is hinged to the front end of the second connecting rod 204b of the fourth pair...; the rear end of the second connecting rod 204b of the first pair is hinged to the front end of the first connecting rod 204a of the second pair, the rear end of the first connecting rod 204a of the second pair is hinged to the front end of the second connecting rod 204b of the third pair, the rear end of the second connecting rod 204b of the third pair is hinged to the front end of the first connecting rod 204a of the fourth pair...

[0039] When the included angle between the first connecting rod 204a and the second connecting rod 204b near one end of the first support rod 201 increases, the corresponding angles between the other pairs of the first connecting rod 204a and the second connecting rod 204b synchronously become larger. When the included angle between the first connecting rod 204a and the second connecting rod 204b near one end of the first support rod 201 decreases, the corresponding angles between the other pairs of the first connecting rod 204a and the second connecting rod 204b synchronously become smaller.

[0040] That is, the included angle between the first connecting rod 204a and the second connecting rod 204b can be synchronously increased or decreased so that the telescopic rod assembly 204 is shortened or lengthened.

[0041] Wherein, a first sliding groove 205 is provided on the first support rod 201. The first connecting rod 204a near the first support rod 201 is slidably connected to the first sliding groove 205 through a pin shaft, and the second connecting rod 204b near the first support rod 201 is hinged to the first support rod 201 through a pin shaft.

[0042] Preferably, a second sliding groove 206 is provided on the second support rod 202. The second connecting rod 204b near the second support rod 202 is slidably connected to the second sliding groove 206 through a pin shaft, and the first connecting rod 204a near the second support rod 202 is hinged to the second support rod 202.

[0043] It should be noted that the telescopic member 200 further includes a transmission rod 203. One end of the transmission rod 203 is fixedly connected to the moving member 105, and the other end of the transmission rod 203 is hinged to the first connecting rod 204a near the first support rod 201. The connection mode of the transmission rod 203 and the first connecting rod 204a is such that the telescopic direction of the telescopic member 200 is parallel to the axial direction of the driven shaft 104, and the driving force provided by the driving member 100 is transmitted after being rotated by 90 degrees.

[0044] In use, shake the hand crank 101, the drive shaft 102 rotates with the hand crank 101, and the driven shaft 104 rotates synchronously under the drive of the transmission belt 103, so that the moving member 105 moves along the axial direction of the driven shaft 104;

[0045] In this embodiment, when the telescopic member 200 extends, shake the hand crank 101 clockwise, so that the moving member 105 moves away from the hand crank 101. The transmission rod 203 drives the first connecting rod 204a to move downward along the first chute 205. The included angle between the first connecting rod 204a and the second connecting rod 204b at one end of the first support rod 201 decreases, and the ends of the first connecting rod 204a and the second connecting rod 204b away from the first support rod 201 can move from being close to the first support rod 201 to being away from the first support rod 201.

[0046] It should be noted that during the extension process of the telescopic member 200, the second connecting rod 204b close to the second support rod 202 slides downward along the second chute 206, and the first connecting rod 204a close to the second support rod 202 rotates along the second support rod 202.

[0047] The other pairs of the first connecting rod 204a and the second connecting rod 204b move synchronously away from the first support rod 201 due to the hinge connection, so that the second support rod 202 moves away from the first support rod 201, and the entire telescopic member 200 extends.

[0048] When the telescopic member 200 shortens, shake the hand crank 101 counterclockwise, so that the moving member 105 moves closer to the hand crank 101. The transmission rod 203 drives the first connecting rod 204a to move upward along the first chute 205, so that the included angle between the first connecting rod 204a and the second connecting rod 204b at one end of the first support rod 201 increases, and the ends of the first connecting rod 204a and the second connecting rod 204b away from the first support rod 201 can move from being away from the first support rod 201 to being close to the first support rod 201.

[0049] It should be noted that during the shortening process of the telescopic member 200, the second connecting rod 204b close to the second support rod 202 slides upward along the second chute 206, and the first connecting rod 204a close to the second support rod 202 rotates along the second support rod 202.

[0050] The other pairs of the first connecting rod 204a and the second connecting rod 204b move synchronously closer to the first support rod 201 due to the hinge connection, so that the second support rod 202 moves closer to the first support rod 201, and the entire telescopic member 200 shortens.

[0051] Embodiment 2, refer to Figure 3, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides another implementation manner of the driven shaft of the telescopic rod mechanism, improving the efficiency of the driving component.

[0052] Specifically, the preset outer diameter of the driven shaft 104 is smaller than the outer diameter of the driving shaft 102. The outer diameter of the driven shaft 104 is set to be 1 / 3 to 1 / 2 of the outer diameter of the driving shaft 102. When the hand crank 101 is shaken, for each rotation of the hand crank 101, the driven shaft 104 rotates approximately two circles, improving the extension or retraction efficiency of the telescopic component 200.

[0053] The remaining structures are the same as those in Embodiment 1.

[0054] Embodiment 3, referring to Figures 1 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an auxiliary disassembly device for the exciter rectifier wheel diode, solving the problem that parts are prone to scattering during the disassembly of the diode, and includes the telescopic rod mechanism in the above embodiment.

[0055] It further includes a protection component 300. The protection component 300 can be installed on the exciter rotor to prevent parts from scattering during the disassembly of the diode.

[0056] The protection component 300 includes a circumferential protection assembly 301. The circumferential protection assembly 301 can be fixed to the exciter rotor along the circumferential direction, so that the entire protection component 300 is fixed to the exciter rotor.

[0057] Specifically, the circumferential protection assembly 301 includes a circumferential protection member 301a. The circumferential protection member 301a is adapted to fit the surface of the exciter rotor, and a protection layer, such as non-woven fabric, etc., is bonded to the side in contact with the exciter rotor to avoid damaging the surface of the exciter rotor.

[0058] Furthermore, the protection component 300 further includes a first protection member 304 and a second protection member 305. The first protection member 304 and the second protection member 305 are perpendicular to the circumferential protection member 301a and are respectively fixedly connected to both sides of the circumferential protection member 301a; the first protection member 304 and the second protection member 305 are symmetrically arranged and are both of a housing structure; the bottom surface shapes of the first protection member 304 and the second protection member 305 are adapted to fit the surface of the exciter rotor, and at the same time, a protection layer is bonded to the side in contact with the surface of the exciter rotor for both the first protection member 304 and the second protection member 305.

[0059] And telescopic sleeves 306. There are two groups of telescopic sleeves 306 arranged symmetrically, which are respectively connected to the first protection member 304 and the second protection member 305 in a through manner.

[0060] The bottom surface radian of the telescopic sleeve 306 is the same as the bottom surface radian of the circumferential protection member 301a to facilitate the telescopic sleeve 306 to fit the surface of the exciter rotor.

[0061] It should be noted that in this embodiment, the telescopic sleeve 306 is set to three sections, namely the first sleeve 306a, the second sleeve 306b and the third sleeve 306c. The outer diameters of the first sleeve 306a, the second sleeve 306b and the third sleeve 306c gradually decrease to adapt to the reciprocating sliding of the third sleeve 306c in the second sleeve 306b and the reciprocating sliding of the second sleeve 306b in the first sleeve 306a.

[0062] Furthermore, a first sleeve guide groove 306d is provided on the inner wall of the first sleeve 306a. The first sleeve guide groove 306d is arranged along the axial direction of the first sleeve 306a, and both ends of the first sleeve guide groove 306d are closed. A second sleeve rib 306e is provided on the side of the second sleeve 306b opposite to the first sleeve guide groove 306d. The second sleeve rib 306e is adapted to slide in the first sleeve guide groove 306d. When the second sleeve rib 306e slides to both ends of the first sleeve guide groove 306d, due to the closed arrangement of both ends of the first sleeve guide groove 306d, the second sleeve rib 306e is prevented from slipping out of the first sleeve guide groove 306d, that is, the second sleeve 306b is prevented from slipping out of the first sleeve 306a.

[0063] Furthermore, a second sleeve guide groove 306f is provided on the inner wall of the second sleeve 306b. The second sleeve guide groove 306f is arranged along the axial direction of the second sleeve 306b, and both ends of the second sleeve guide groove 306f are closed. A third sleeve rib 306g is provided on the side of the third sleeve 306c opposite to the second sleeve guide groove 306f. The third sleeve rib 306g is adapted to slide in the second sleeve guide groove 306f. When the third sleeve rib 306g slides to both ends of the second sleeve guide groove 306f, due to the closed arrangement of both ends of the second sleeve guide groove 306f, the third sleeve rib 306g is prevented from slipping out of the second sleeve guide groove 306f, that is, the third sleeve 306c is prevented from slipping out of the second sleeve 306b.

[0064] Among them, driving components 100 are respectively installed in the first protective member 304 and the second protective member 305.

[0065] Taking the first protective member 304 as an example for illustration, specifically, an installation hole is provided on the side wall at one end of the first protective member 304. A bearing is installed in the installation hole. The driving shaft 102 is installed in the bearing passing through the side wall of the first protective member 304 and extends into the interior of the first protective member 304; bearings are respectively installed on the opposite side walls at the other end of the first protective member 304. Both ends of the driven shaft 104 are respectively rotatably installed in the two bearings at the other end of the first protective member 304, so that the driven shaft 104 can rotate synchronously with the driving shaft 102 under the drive of the transmission belt 103.

[0066] In order to facilitate the telescopic sleeve 306 to extend between the diodes of the exciter commutator wheel during the use of the entire device, so that the entire device forms a complete protective circle around the surface of the exciter rotor, preventing parts from scattering during the disassembly of the exciter commutator wheel diodes, the telescopic sleeve 306 is arranged perpendicular to the first protective member 304, that is, the telescopic member 200 is perpendicularly connected to the protective member 300, and the telescopic direction of the telescopic member 200 is parallel to the axial direction of the driven shaft 104.

[0067] Telescopic members 200 are respectively installed in the symmetrically arranged telescopic sleeves 306. Taking the telescopic sleeve 306 on the side close to the first protective member 304 as an example for illustration. Specifically, the first support rod 201 is fixedly installed in the first protective member 304, and the second support rod 202 is fixedly installed at one end of the third sleeve 306c located inside the second sleeve 306b.

[0068] When the telescopic sleeve 306 needs to be extended, the second support rod 202 pushes the third sleeve 306c to move outward from the second sleeve 306b. After the third sleeve rib 306g contacts the closed end of the second sleeve guide groove 306f away from the first sleeve 306a, through the cooperation of the third sleeve rib 306g and the closed end of the second sleeve guide groove 306f away from the first sleeve 306a, the second sleeve 306b is pushed outward from the first sleeve 306a. When the second sleeve rib 306e contacts the closed end of the first sleeve guide groove 306d away from the first support rod 201, it is the maximum extension distance of the telescopic member 200. At this time, the two telescopic sleeves 306 are in contact with each other.

[0069] When the telescopic sleeve 306 needs to be retracted, the second support rod 202 drives the third sleeve 306c to move inward from the second sleeve 306b. After the third sleeve rib 306g contacts the closed end of the second sleeve guide groove 306f close to the first sleeve 306a, through the cooperation of the third sleeve rib 306g and the closed end of the second sleeve guide groove 306f close to the first sleeve 306a, the second sleeve 306b is pushed inward from the first sleeve 306a. When the second sleeve rib 306e contacts the closed end of the first sleeve guide groove 306d close to one end of the first support rod 201, it is the retracted state of the telescopic member 200.

[0070] Preferably, the protective member 300 further includes clamping jaws 302. The clamping jaws 302 are respectively arranged at both ends of the circumferential protective member 301a. A torsion spring 303 is arranged between the clamping jaws 302 and the circumferential protective member 301a. The arrangement of the torsion spring 303 enables the clamping jaws 302 to maintain a torsional force that rotates towards the center of the circumferential protective member 301a.

[0071] Preferably, a purge pipe 301b is provided on one side of the circumferential protection member 301a. A number of nozzles are provided on the purge pipe 301b. The purge pipe 301b can be externally connected to an intake pipe. When needed, the intake valve is opened, and the number of nozzles simultaneously blow air onto the surface of the exciter rotor to blow off dust and the like.

[0072] Preferably, a lighting lamp 301c is provided on the other side of the circumferential protection member 301a, and a lighting switch 301d is provided on the top of the circumferential protection member 301a. The lighting lamp 301c increases the lumen value on the surface of the exciter rotor.

[0073] All other structures are the same as those in Embodiment 2.

[0074] During use, the telescopic sleeve 306 is in a retracted state. The jaws 302 are pulled to both sides respectively, and the whole device is placed on the corresponding exciter rotor surface of the exciter rectifier wheel diode to be disassembled. The first protection member 304 and the second protection member 305 are simultaneously inserted under the diode. The jaws 302 are released, and the jaws 302 are clamped on the exciter rectifier wheel by the elastic force of the torsion spring;

[0075] The hand crank 101 is shaken to drive the telescopic sleeve 306 to extend, completing the enclosure of the diode at the disassembly part by the device, and forming a rectangular guardrail on the exciter rotor surface by the whole device. The accessories falling off during the disassembly process fall into the guardrail, which is convenient for the operator to collect the falling accessories and avoid the accessories falling into the small gaps inside the rectifier wheel, resulting in production accidents.

[0076] During the actual use process, during the disassembly process, the exciter is turned to the position of the diode to be disassembled. A cushion with a certain thickness is laid on the transition surface between the rectifier wheel and the exciter rotor. The hand cranks 101 on both sides are shaken to adjust the telescopic sleeve 306 to the retracted position. The whole device is placed on the contact surface of the exciter rotor. The lighting switch 301d is pressed to turn on the lighting lamp 301c to facilitate the disassembly and assembly work. The hand cranks 101 on both sides are rotated to extend the telescopic sleeve 306 and make them abut against each other. Use a special open-end wrench M to loosen the lock nut of the exciter rotating rectifier fuse, remove the screw stop washer on the rectifier wheel for fixing the fuse, loosen the screw on the rectifier wheel for fixing the fuse, and remove the rectifier fuse. Each fuse should be marked. The rotor is turned to make the rectifier wheel rotate to a position convenient for removing the fuse, and each group of fuses is successively removed. The DC resistance of the fuse is measured. If it is unqualified, the fuse is replaced. The weight balance should be checked before replacing the fuse. The burrs on the steel surface of the rectifier wheel are polished with metallographic sandpaper, and the silver-plated surface is wiped with a fine cloth. Vaseline should be applied to all conductive surfaces after disassembly and cleaning. When reinstalling, the fuse and the rectifier wheel bolt are tightened with a torque wrench. The gap between the L-shaped bottom plate of the fuse and the rectifier wheel is controlled at the minimum value of the feeler gauge, which is 0.03 mm. The lock screw should be replaced after removal.

[0077] The purge pipe 301b is externally connected to the intake pipe. When needed, open the intake valve, and the nozzle blows air to the outside of the rectifying wheel simultaneously to blow off dust, etc. Clean it with a white fine cloth dipped in a special cleaning agent, and check that there should be no oil stains.

[0078] According to the electrical test situation, determine whether the rectifying wheel diode is qualified. If it is unqualified, disassemble and assemble it with a special open-end wrench M. Loosen the lead self-locking nut of the rectifying wheel diode assembly and the arm bridge, use a special flat-head socket to loosen the red epoxy resin bolt that fixes the diode assembly on the rectifying wheel, and remove the diode assembly. Loosen the clamping bolt of the diode assembly, remove the two diodes in each group, clean them and then test them separately. If they are unqualified, weigh them, select a diode with a similar weight from the spare parts (already tested and qualified), clamp the radiator with a bench vice (pad rubber pads or paper pads on both sides of the bench vice), install the gasket and the qualified diode, drop two drops of LOCTITE 243 glue into the fixing screw holes of the radiator, install the upper fixing clip of the diode, and clamp it with a special clamping tool, and tighten it with a 23NM torque wrench. Check the distance between the diode and the lower gasket, which should be between 0.1 - 0.3 (±0.05) mm. After assembly, send the assembly to the test laboratory for inspection and qualification before preparing for reinstallation. Reinstall the diode assembly in place, fix it on the rectifying wheel with two special countersunk socket head cap screws. After tightening, first loosen and remove one socket head cap screw, replace it with a red epoxy resin bolt and screw it on. When it is almost screwed to the bolt head, drop two drops of LOCTITE 454 glue into the gap between the red epoxy resin bolt and the rectifying wheel surface, and tighten it with a 5NM torque wrench.
