Description

Technical Field

[0001] The utility model relates to the technical field of two-stage transmission push rod motors, in particular to a two-stage transmission push rod motor. Background Art

[0002] A two-stage transmission push rod motor is a device that converts the rotational motion of an electric motor into the linear reciprocating motion of a push rod. It is usually composed of a drive motor, reduction gears, screws, nuts, push rods, springs, micro-control switches, etc. The two-stage transmission means that in addition to the deceleration of the motor itself, the entire transmission system also includes an additional deceleration stage, which is usually achieved through a screw-nut mechanism.

[0003] The output end of the existing two-stage transmission push rod motor is connected to the transmission shaft by a bolt assembly, which makes it inconvenient to disassemble and assemble the output end of the two-stage transmission push rod motor and the transmission shaft.

[0004] Therefore, we propose a two-stage transmission push rod motor that can quickly disassemble and assemble the output end of the two-stage transmission push rod motor and the transmission shaft, making the push rod motor more convenient to use. Utility Model Content

[0005] The purpose of the present utility model is to provide a two-stage transmission push rod motor to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a two-stage transmission push rod motor, comprising a body, a transmission rod being clamped on the outside of the body, and a processing component arranged on the outside of the body, the processing component comprising a clamping component arranged on the outside of the body, and an auxiliary component being arranged inside the clamping component.

[0007] Preferably, the clamping assembly includes an output end sleeve fixedly mounted on the outer wall of the body, a clamping block is slidingly arranged inside the output end sleeve, a sliding column is fixedly mounted on the outer wall of the clamping block, a slip ring is slidingly arranged on the outer wall of the output end sleeve, a sliding groove is provided on the outer wall of the slip ring, an inclined groove is provided on the inner wall of the sliding groove, a sliding rod is slidingly arranged inside the slip ring, a spring is sleeved on the outer wall of the sliding rod, and a clamping groove is provided on the outer wall of the transmission rod.

[0008] Preferably, the auxiliary component includes a first magnetic block fixedly mounted on the inner bottom surface of the output end sleeve, a second magnetic block is arranged above the first magnetic block, a push plate is fixedly mounted on one end of the second magnetic block away from the first magnetic block, and a rubber pad is fixedly mounted on the side of the push plate away from the second magnetic block.

[0009] Preferably, the inclined groove is opened at an angle, and the outer wall of the sliding column and the inner wall of the inclined groove are slidingly arranged. Under the restriction, when the inclined groove squeezes the sliding column, the sliding column can drive the block to slide inside the output end sleeve.

[0010] Preferably, the slide rod is fixedly mounted on the outer wall of the body, and the slip ring is slidably arranged on the outer wall of the slide rod. Under the restriction of the slide rod, the spring can stably apply pressure to the top surface of the slip ring.

[0011] Preferably, the first magnetic block and the second magnetic block magnetically repel each other, and the first magnetic block and the second magnetic block are aligned. Under the restriction of the magnetic repulsion between the first magnetic block and the second magnetic block, the transmission rod can be pushed, so that the transmission rod is more stably installed inside the output end sleeve.

[0012] Preferably, the rubber pad is made of rubber material, and the outer wall of the rubber pad is slidably arranged with the inner wall of the output end sleeve. Under the restriction of the rubber pad, the friction coefficient between the rubber pad and the end of the transmission rod can be increased.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The spring set on the outer wall of the slide rod is not compressed at this time, and under the elastic action of the spring, the slip ring is pushed downward, causing the inclined groove and the slide column to slide and squeeze, so that the slide column drives the block to slide toward the outside of the output end sleeve. The output end sleeve slides inside to engage the card block with the card slot. This structure can quickly disassemble and assemble the transmission rod and the body. The first-level transmission is driven by a worm gear, which converts the transmission torque to ninety degrees. The second-level transmission is driven by a bevel gear, which converts the transmission torque to one hundred and eighty degrees, so that the motor and the push rod are parallel, reducing the installation space. The use of a hexagonal transmission rod increases the torsional force compared to a round shaft, making it less likely to slip when the shaft rotates. An oil seal is pressed on the bearing end of the shaft, which can not only seal and prevent dust, but also support the bearing and offset the axial clearance of the bearing. A pair of bevel gears are selected for transmission, which can redirect the torque almost without loss, and the number of teeth of the two bevel gears can be adjusted to achieve the purpose of increasing the torque. The bearing stop adopts a threaded structure, which can better press the bearing and prevent dust, forming a closed space with the oil seal of the front section. Two notches are added to the front end of the stop for easy installation.

[0015] 2. The two-stage transmission push rod motor is composed of an auxiliary component as one of its components. When the transmission rod is plugged into the output end sleeve, the end of the transmission rod contacts and squeezes the rubber pad, causing the rubber pad, push plate, and second magnetic block to slide into the inside of the output end sleeve. Due to the magnetic repulsion between the first magnetic block and the second magnetic block, when the slot opened on the outer wall of the transmission rod is engaged with the card block, the rubber pad and the end of the transmission rod are pushed tightly together under the restriction of the magnetic repulsion between the first magnetic block and the second magnetic block, and transmission rods of different sizes can be installed. This structure can be used to install a shorter transmission rod and the output end sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] The preferred embodiment of the two-stage transmission push rod motor provided by the present utility model is as follows: Figures 1 to 6 Shown: a two-stage transmission push rod motor, including a body 1;

[0026] A transmission rod 2 is clamped on the outside of the body 1;

[0027] And a processing component 3 is arranged outside the body 1, the processing component 3 includes a clamping component 31 arranged outside the body 1, the clamping component 31 includes an output end sleeve 311 fixedly installed on the outer wall of the body 1, a clamping block 312 is slidably provided inside the output end sleeve 311, a sliding column 313 is fixedly installed on the outer wall of the clamping block 312, a slip ring 314 is slidably provided on the outer wall of the output end sleeve 311, a sliding groove 315 is provided on the outer wall of the sliding ring 314, an inclined groove 316 is provided on the inner wall of the sliding groove 315, a sliding rod 317 is slidably provided inside the slip ring 314, a spring 318 is sleeved on the outer wall of the sliding rod 317, and a clamping groove 319 is provided on the outer wall of the transmission rod 2.

[0028] In this embodiment, when the body 1 and the transmission rod 2 need to be disassembled, the slip ring 314 is slid upward, the sliding groove 315 provided on the outer wall of the slip ring 314 is slidably arranged with the outer wall of the block 312, and the inclined groove 316 provided inside the sliding groove 315 is slidably arranged with the sliding post 313 fixedly installed on the outer wall of the block 312. Since the inclined groove 316 is inclined, under its restriction, the inclined groove 316 slides and squeezes the sliding post 313, so that the sliding post 313 drives the block 312 to slide toward the outside of the output end sleeve 311. At this time, the block 312 is no longer engaged with the slot 319 provided on the outer wall of the transmission rod 2. The transmission rod 2 can be pulled out from the output end sleeve 311 to quickly disassemble the transmission rod 2 and the body 1. When the transmission rod 2 needs to be installed with the body 1, the transmission rod 2 is inserted into the output end sleeve 311 fixedly installed on the outer wall of the body 1, the slot 319 is aligned with the block 312, and the slip ring 314 is loosened. At this time, the spring 318 provided on the outer wall of the slide rod 317 is not compressed. Under the elastic action of the spring 318, the slip ring 314 is pushed downward. The movement causes the inclined groove 316 and the sliding column 313 to slide and squeeze, so that the sliding column 313 drives the block 312 to slide inside the output end sleeve 311, so that the block 312 is engaged with the slot 319. This structure can quickly disassemble the transmission rod 2 and the body 1. The first-level transmission is driven by the worm gear, so that the transmission torque is converted to 90 degrees; the second-level transmission is driven by the bevel gear, so that the transmission torque is converted to 180 degrees, so that the motor and the push rod are parallel, reducing the installation space. Using a hexagonal transmission rod 2, compared with The round shaft increases the torsional force, making it less likely to slip when the shaft rotates. An oil seal is pressed on the bearing end of the shaft, which not only seals and prevents dust, but also supports the bearing and offsets the axial clearance of the bearing. A pair of bevel gears are used for transmission, which can redirect the torque almost without loss, and the number of teeth of the two bevel gears can be adjusted to increase the torque. The bearing block adopts a threaded structure, which can better press the bearing and prevent dust, forming a closed space with the oil seal at the front; two notches are added to the front end of the block for easy installation.

[0029] Furthermore, the inclined groove 316 is opened at an angle, and the outer wall of the sliding column 313 and the inner wall of the inclined groove 316 are slidingly arranged. Under the restriction, when the inclined groove 316 squeezes the sliding column 313, the sliding column 313 can drive the block 312 to slide inside the output end sleeve 311.

[0030] Furthermore, the slide rod 317 is fixedly installed on the outer wall of the body 1, and the slip ring 314 is slidingly arranged on the outer wall of the slide rod 317. Under the restriction of the slide rod 317, the spring 318 can stably apply pressure to the top surface of the slip ring 314.

[0031] Example 2

[0032] On the basis of Example 1, the preferred embodiment of the two-stage transmission push rod motor provided by the present invention is as follows: Figures 1 to 6 As shown: the auxiliary component 32 includes a first magnetic block 321 fixedly mounted on the inner bottom surface of the output end sleeve 311, a second magnetic block 322 is arranged above the first magnetic block 321, a push plate 323 is fixedly mounted on the end of the second magnetic block 322 away from the first magnetic block 321, and a rubber pad 324 is fixedly mounted on the side of the push plate 323 away from the second magnetic block 322.

[0033] In this embodiment, when the transmission rod 2 is plugged into the output end sleeve 311, the end of the transmission rod 2 contacts and squeezes the rubber pad 324, causing the rubber pad 324, the push plate 323, and the second magnetic block 322 to slide into the inside of the output end sleeve 311. Due to the magnetic repulsion between the first magnetic block 321 and the second magnetic block 322, when the slot 319 opened on the outer wall of the transmission rod 2 is engaged with the block 312, the rubber pad 324 and the end of the transmission rod 2 are pushed tightly together under the restriction of the magnetic repulsion between the first magnetic block 321 and the second magnetic block 322, and transmission rods 2 of different sizes can be installed. This structure can be used to install a shorter transmission rod 2 and the output end sleeve 311.

[0034] Furthermore, the first magnetic block 321 and the second magnetic block 322 magnetically repel each other, and the first magnetic block 321 and the second magnetic block 322 are aligned. Under the restriction of the magnetic repulsion between the first magnetic block 321 and the second magnetic block 322, the transmission rod 2 can be pushed, so that the transmission rod 2 is more stably installed inside the output end sleeve 311.

[0035] In addition, the rubber pad 324 is made of rubber material, and the outer wall of the rubber pad 324 is slidably arranged with the inner wall of the output end sleeve 311. Under the restriction of the rubber pad 324, the friction coefficient between it and the end of the transmission rod 2 can be increased.
