Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment technology, and in particular to a telescopic structure for electromechanical applications. Background Technology

[0002] Electromechanical equipment refers to products that combine mechanical and electronic technologies. With the rapid development and widespread application of computer technology, electromechanical equipment has achieved unprecedented development and has become a type of product that integrates computer and information technology, automatic control technology, sensing and detection technology, servo transmission technology and mechanical technology. Electromechanical equipment often requires the use of telescopic mechanisms for lifting and lowering operations.

[0003] Existing technology, such as Chinese Patent Publication No. CN206922577U, discloses an electromechanical telescopic structure, including a housing. A motor is fixedly connected to the bottom of the housing's inner cavity. A ball screw is fixedly connected to the motor's output shaft. The top end of the ball screw penetrates the top of the housing and extends to the outside of the housing. A displacement plate is sleeved on the surface of the ball screw slide. The bottom of the displacement plate is fixedly connected to the ball screw slider. Limiting devices are fixedly connected to both sides of the displacement plate. Teeth that cooperate with the limiting devices are fixedly connected to both sides of the inner cavity of the housing. Support rods are fixedly connected to both sides of the top of the displacement plate. This electromechanical telescopic structure, through improvements to the limiting devices and the coordinated use of the motor, ball screw, displacement plate, and support rods, avoids changes in effective length due to long-term pressure, thus facilitating user operation. However, this utility model uses a combination of a limiting block and a spring, which engages with the teeth to prevent the telescopic mechanism from failing after long-term use. Since the electromechanical equipment has a certain weight, it is difficult to ensure that the limiting block can be locked with the teeth under a large gravitational force by relying solely on the force applied by the spring.

[0004] To address the issue of electromechanical telescopic structures failing and causing equipment to fall rapidly, resulting in damage or injury, existing structures may malfunction after prolonged use, leading to limit failure. Under gravity, the equipment may fall rapidly, potentially causing damage or injury if appropriate braking measures are not taken. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art where electromechanical telescopic structures fail, resulting in the rapid fall of electromechanical equipment, causing damage to itself or accidental injury to people. Therefore, this utility model proposes an electromechanical telescopic structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an electromechanical telescopic structure, comprising a base, a housing, and a telescopic mechanism. The housing is fixedly connected to the surface of the base. The telescopic mechanism is disposed inside the housing. The telescopic mechanism includes a telescopic component, a protective component, an adjusting component, and an auxiliary component. The telescopic component includes a motor, which is fixedly installed on the inner wall of the housing. The output end of the motor is fixedly connected to a rotating shaft, which is rotatably connected to the inner wall of the housing. A gear is fixedly connected to the surface of the rotating shaft, and a rack plate is meshed with the surface of the gear. The rack plate is slidably connected to the inner wall of the housing. A movable plate is fixedly connected to the surface of the rack plate. The protective component includes a fixed shaft, which is fixedly connected to the inner wall of the housing. A pawl is rotatably connected to the surface of the fixed shaft, and the pawl cooperates with the gear. A spring is fixedly connected to the surface of the pawl, and the end of the spring away from the pawl is fixedly connected to the inner wall of the housing. A brake plate is slidably connected to the inner wall of the housing, and the brake plate cooperates with the pawl.

[0007] Furthermore, a limit rod is fixedly connected to the inner wall of the housing, the brake plate is slidably connected to the surface of the limit rod, and a clicker is fixedly connected to the inner wall of the housing, the clicker cooperating with the pawl.

[0008] Furthermore, the adjustment assembly includes a receiving groove, which is formed on the surface of the brake plate. An adjustment plate is slidably connected to the surface of the receiving groove. A positioning hole is formed on the surface of the brake plate, and a positioning rod is slidably connected to the surface of the positioning hole.

[0009] Furthermore, a pull plate is fixedly connected to the surface of the positioning rod, and a second spring is sleeved and connected to the surface of the positioning rod. One end of the second spring is fixedly connected to the surface of the pull plate, and the other end of the second spring is fixedly connected to the surface of the brake plate.

[0010] Furthermore, the surface of the adjusting plate is provided with adjusting holes, and the positioning rod is inserted and connected to the surface of the adjusting holes. The number of adjusting holes is multiple and they are evenly distributed.

[0011] Furthermore, the auxiliary component includes a guide rod, which is fixedly connected to the inner wall of the housing, and the rack plate is slidably connected to the surface of the guide rod.

[0012] Furthermore, a T-shaped groove is provided on the top surface of the adjustment plate, and a soft pad is fixedly connected to the top surface of the adjustment plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a telescopic mechanism is set up. Starting the motor drives the rotating shaft to rotate, causing the gear to rotate and drive the rack plate to move up and down along the guide rod, thus realizing the telescopic operation of the movable plate. When a motor failure causes the braking of the rotating shaft to fail, the electromechanical equipment on the movable plate, under the action of gravity, causes the rack plate to move downwards. After the movable plate descends to a certain height, it contacts the brake plate, causing the brake plate to move downwards along the limit rod. The brake plate squeezes the pawl, causing it to rotate along the fixed shaft and tightening the spring. After rotating a certain angle, one end of the pawl locks the gear, restricting the gear from continuing to rotate, thereby restricting the rack plate from continuing to descend. At the same time, the pawl... One end strikes a clicker to emit an audible warning, preventing damage or injury from the rapid descent of the equipment. The height at which the movable plate descends can be adjusted to engage the brake plate. Simply pull the pull plate to slide the positioning rod along the positioning hole, disengaging it from the adjustment hole and tightening the second spring. Then, reach into the T-slot to grasp the adjustment plate, moving it upwards along the receiving groove a suitable distance. Release the pull plate; the positioning rod will return to its original position under the spring's rebound, locking into the corresponding adjustment hole, thus fixing the adjustment plate in place. The adjustment plate can then be used to adjust the descent height of the movable plate before braking.

[0015] 2. In this utility model, by setting up a telescopic mechanism, the telescopic operation is carried out by using a motor, gears and rack and pinion plates. In the event of motor failure, the gears can be braked by a brake plate and pawls to avoid damage or injury caused by the rapid descent of the electromechanical equipment, thereby effectively improving the safety of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an electromechanical telescopic structure, including a base 1, a housing 2 and a telescopic mechanism 3, wherein the housing 2 is fixedly connected to the surface of the base 1, and the telescopic mechanism 3 is disposed inside the housing 2.

[0024] The specific setup and function of its telescopic mechanism 3 will be explained below.

[0025] In this embodiment: the telescopic mechanism 3 includes a telescopic component 31, a protective component 32, an adjusting component 33, and an auxiliary component 34.

The protective component 32 includes a fixed shaft 321, which is fixedly connected to the inner wall of the outer shell 2. A pawl 322 is rotatably connected to the surface of the fixed shaft 321.

The end of the spring 323 away from the pawl 322 is fixedly connected to the inner wall of the outer shell 2. A brake plate 324 is slidably connected to the inner wall of the outer shell 2. The brake plate 324 cooperates with the pawl 322.

[0026] The effects achieved by the above components are as follows: the starting motor 311 drives the rotating shaft 312 to rotate, causing the gear 313 to rotate and drive the rack plate 314 to move up and down, realizing the extension and retraction operation of the movable plate 315 and the electromechanical equipment on it. When the movable plate 315 falls rapidly, it contacts the brake plate 324 and presses it downward, causing the brake plate 324 to push the pawl 322 to rotate along the fixed shaft 321. After rotating a certain angle, the pawl 322 locks the gear 313, thereby limiting the rapid descent of the rack plate 314.

[0028] The effects achieved by the above components are as follows: the limit rod 325 provides guidance and limit for the movement of the brake plate 324; the clicker 326 is provided so that when one end of the pawl 322 engages the gear 313 after a certain rotation angle, the other end of the pawl 322 strikes the clicker 326 to emit an audible warning.

[0029] Specifically, the adjustment component 33 includes a receiving groove 331, which is formed on the surface of the brake plate 324. An adjustment plate 332 is slidably connected to the surface of the receiving groove 331. A positioning hole 333 is formed on the surface of the brake plate 324. A positioning rod 334 is slidably connected to the surface of the positioning hole 333.

[0030] The effects achieved by the above components are as follows: the receiving groove 331 is provided to facilitate the receiving of the adjusting plate 332; the adjusting plate 332 is provided to facilitate the selection of how much height the movable plate 315 should descend before braking, as needed; and the positioning hole 333 and the positioning rod 334 are provided to cooperate with the adjusting hole 337 to fix the adjusting plate 332.

[0031] Specifically, a pull plate 335 is fixedly connected to the surface of the positioning rod 334, and a second spring 336 is sleeved and connected to the surface of the positioning rod 334. One end of the second spring 336 is fixedly connected to the surface of the pull plate 335, and the other end of the second spring 336 is fixedly connected to the surface of the brake plate 324.

[0032] The effects achieved by the above components are as follows: the pull plate 335 is provided to facilitate pulling the positioning rod 334, and the spring 336 is provided to both lock the positioning rod 334 into the adjustment hole 337 and to facilitate the reset of the positioning rod 334 by utilizing its rebound effect.

[0033] Specifically, the surface of the adjusting plate 332 is provided with adjusting holes 337, and the positioning rod 334 is inserted and connected to the surface of the adjusting holes 337. The number of adjusting holes 337 is multiple and they are evenly distributed.

[0034] The effects achieved by the above components are as follows: the adjustment hole 337 is provided to fix the adjustment plate 332 in conjunction with the positioning hole 333 and the positioning rod 334; and multiple sets of adjustment holes 337 are provided to allow the adjustment plate 332 to be fixed at multiple heights.

[0035] Specifically, the auxiliary component 34 includes a guide rod 341, which is fixedly connected to the inner wall of the housing 2, and the rack plate 314 is slidably connected to the surface of the guide rod 341.

[0036] The effect achieved by the above components is as follows: the guide rod 341 provides guidance and limit for the movement of the rack plate 314, and increases the stability during the extension and retraction process.

[0037] Specifically, a T-slot 342 is provided on the top surface of the adjusting plate 332, and a soft pad 343 is fixedly connected to the top surface of the adjusting plate 332.

[0038] The effects achieved by the above components are as follows: the T-slot 342 is provided to facilitate gripping of the adjustment plate 332, and the soft pad 343 is provided to prevent the movable plate 315 from making hard contact with the adjustment plate 332 and causing damage.

[0039] Working principle: By setting up the telescopic mechanism 3, the motor 311 drives the rotating shaft 312 to rotate, causing the gear 313 to rotate and drive the rack plate 314 to move up and down along the guide rod 341, realizing the telescopic operation of the movable plate 315. When the motor 311 fails and the braking of the rotating shaft 312 fails, the electromechanical equipment on the movable plate 315 causes the rack plate 314 to move downward under the action of gravity. After the movable plate 315 descends to a certain height, it contacts the brake plate 324, causing the brake plate 324 to move downward along the limit rod 325. The brake plate 324 squeezes the pawl 322, causing it to rotate along the fixed shaft 321 and tighten the spring 323. After rotating a certain angle, one end of the pawl 322 locks the gear 313, restricting the gear 313 from continuing to rotate, thereby restricting the rack plate 314 from continuing to descend. At the same time, the pawl 322... 22 The other end strikes the clicker 326 to emit an audible warning, preventing damage or injury caused by the rapid descent of the electromechanical equipment. The height at which the movable plate 315 descends before contacting the brake plate 324 can be adjusted as needed. Simply pull the pull plate 335 to slide the positioning rod 334 along the positioning hole 333, disengaging the positioning rod 334 from the adjustment hole 337 and tightening the second spring 336. Then, reach into the T-slot 342 to grasp the adjustment plate 332, moving it upwards along the receiving groove 331 a suitable distance. Release the pull plate 335, and the positioning rod 334 will return to its original position under the rebound of the second spring 336, locking into the corresponding adjustment hole 337, thus fixing the adjustment plate 332. The height at which the movable plate 315 descends can then be adjusted using the adjustment plate 332 for braking.

[0040] By setting up the telescopic mechanism 3, the telescopic operation is carried out by the motor 311, gear 313 and rack plate 314. In the event of a failure of the motor 311, the brake plate 324 and the pawl 322 can be used to brake the gear 313 to avoid damage or injury caused by the rapid descent of the electromechanical equipment, thus effectively improving the safety of the equipment.
