Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a telescopic structure of a telescopic motor. Background Art

[0002] Chinese patent application number: "CN202410490256.9" discloses a reciprocating telescopic and vibrating motor drive mechanism. This invention can drive the outer frame to move along the guide rail by setting a telescopic drive component, and the guide rail drives the drive shaft to move synchronously, so that the drive shaft can telescope on the rotating motor, so that the whole has the function of reciprocating telescopic and vibrating, thereby improving efficiency.

[0003] However, the main body of this structure is supported by the guide rail, which makes its structural strength low and thus poor in stability, resulting in greater resistance to the transmission of the screw, affecting the driving effect;

[0004] To this end, this case will propose a new telescopic structure to improve the stability of components such as the "external frame" in the above case. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art such as low stability, and to propose a telescopic structure of a telescopic motor.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A telescopic structure of a telescopic motor is designed, comprising a rotating shaft base, a support base fixedly mounted on the upper end of the rotating shaft base, a drive shaft rotatably connected to the interior of the support base, a sliding assembly slidably connected to the periphery of the upper end of the support base, and a drive assembly for driving the drive shaft to rotate fixedly mounted on the lower end of the rotating shaft base;

[0008] The sliding assembly includes a sliding ring and a sliding cylinder fixedly connected to each other by multiple groups of fixing parts. A limiting groove is provided on the outer end surface of the upper end of the support base. The inner end surfaces of the sliding ring and the sliding cylinder are respectively provided with a first limiting protrusion and a second limiting protrusion that cooperate with the limiting groove. A mounting hole is provided between the sliding ring and the sliding cylinder, and a diamond-shaped sliding block that cooperates with the drive shaft is rotatably connected inside the mounting hole.

[0009] Preferably, the drive assembly includes a gear box and a motor that are transmission-connected, the input end of the gear box is transmission-connected to the output end of the motor, and the output end of the gear box is transmission-connected to the drive shaft.

[0010] Preferably, a first stabilizing shaft is provided on the upper end surface of the rotating shaft base, the lower end of the driving shaft is rotatably sleeved on the periphery of the first stabilizing shaft, a second stabilizing shaft is integrally formed on the upper end of the driving shaft, and a stabilizing hole that cooperates with the second stabilizing shaft is provided on the upper end of the supporting base.

[0011] Preferably, a plurality of first positioning protrusions are provided on the periphery of the upper end surface of the rotating shaft base, and a plurality of fixing holes matching with the first positioning protrusions are provided on the lower end of the supporting base.

[0012] Preferably, the upper end surface of the sliding ring is provided with second positioning protrusions on both the left and right sides of the mounting hole, which can be movably inserted into the interior of the sliding cylinder.

[0013] Preferably, the longitudinal section of the support base is a "T"-shaped structure.

[0014] Preferably, a groove is longitudinally provided on the inner end surface of the sliding cylinder.

[0015] The telescopic structure of a telescopic motor proposed in the present invention has the following beneficial effects:

[0016] Through the mutual cooperation between the sliding assembly and the support base, the first limiting protrusion and the second limiting protrusion on the sliding assembly can be slidably engaged with the inside of the limiting groove, so that the sliding assembly can only slide up and down along the support base, and the embracing sleeve design of the sliding cylinder and the support base makes the sliding between the two more stable. Compared with the "guide rail" and other structures mentioned in the background technology, it has higher stability and structural strength, thereby making the rotation of the drive shaft smoother;

[0017] The detachable setting between the sliding ring and the sliding cylinder makes it easy to replace the sliding block inside the mounting hole, and at the same time makes it easy to separate the sliding assembly from the support base. It can be separated by simply removing the fixing part and taking out the sliding block. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-5 Here is an example of how the subject can be implemented:

[0029] A telescopic structure of a telescopic motor includes a rotating shaft base 1, a support base 2 is fixedly installed on the upper end of the rotating shaft base 1, a drive shaft 3 is rotatably connected to the inner part of the support base 2, a sliding assembly is slidably connected to the outer periphery of the upper end of the support base 2, and a drive assembly for driving the drive shaft 3 to rotate is fixedly installed on the lower end of the rotating shaft base 1; the sliding assembly includes a sliding ring 4 and a sliding cylinder 5 fixedly connected by multiple groups of fixing members 502 at the upper and lower ends, the fixing members 502 can be screws, and a limiting slot 20 is provided on the outer end surface of the upper end of the support base 2 1. The inner end surfaces of the sliding ring 4 and the sliding cylinder 5 are respectively provided with a first limiting protrusion 401 and a second limiting protrusion 501 that cooperate with the limiting notch 201. A mounting hole 402 is provided between the sliding ring 4 and the sliding cylinder 5. A diamond-shaped sliding block that cooperates with the drive shaft 3 is rotatably connected inside the mounting hole 402. The diamond-shaped sliding block and the drive shaft 3 cooperate with each other so that the diamond-shaped sliding block can slide back and forth along the drive shaft 3 when the drive shaft 3 rotates. The upper end of the diamond-shaped sliding block can be integrally formed with a rotating shaft and rotates inside the mounting hole 402.

[0030] Based on the above, the outer end surface of the drive shaft 3 is provided with sliding grooves in the prior art; wherein the sliding cylinder 5 is a movable part, which is completely slidably sleeved on the support base 2, so that the stability is higher. The rotation of the drive shaft 3 in the support base 2 is more stable and reduces contact with the outside. At the same time, the drive shaft 3 does not play a load-bearing role, thereby improving the smoothness of the transmission.

[0031] Furthermore, a first stabilizing shaft 101 is provided on the upper end surface of the rotating shaft base 1, and the lower end of the driving shaft 3 is rotatably sleeved on the outer periphery of the first stabilizing shaft 101. A second stabilizing shaft 301 is integrally formed on the upper end of the driving shaft 3, and a stabilizing hole 203 is provided on the upper end of the supporting base 2 to cooperate with the second stabilizing shaft 301.

[0032] Furthermore, the outer periphery of the upper end surface of the shaft base 1 is provided with multiple sets of first positioning protrusions 102, and the lower end of the support base 2 is provided with multiple sets of fixing holes 202 that match the first positioning protrusions 102 to improve the structural strength;

[0033] Furthermore, the upper end surface of the sliding ring 4 is provided with second positioning protrusions 403 on both sides of the mounting hole 402, which can be movably inserted into the interior of the sliding cylinder 5, so as to improve the direction determination during assembly, make assembly more convenient, and improve the structural strength, so that it does not rely solely on the fixing piece 502;

[0034] Furthermore, the longitudinal section of the support base 2 is a "T"-shaped structure;

[0035] Furthermore, a groove 503 is longitudinally formed on the inner end surface of the sliding cylinder 5 .

[0036] Reference Figure 2 Here is an example of how the drive component may be implemented:

[0037] The driving assembly includes a gear box 7 and a motor 6 that are transmission-connected. The input end of the gear box 7 is transmission-connected to the output end of the motor 6, and the output end of the gear box 7 is transmission-connected to the drive shaft 3, which has the effect of driving and changing speed.

[0038] Last addition:

[0039] The sliding cylinder 5 can be used to install external components to drive the external components to move telescopically and reciprocatingly.

[0040] Based on the above implementation examples, when used:

[0041] Sleeve the lower end of the drive shaft 3 around the periphery of the first stabilizing shaft 101 on the shaft base 1, sleeve the support base 2 around the periphery of the drive shaft 3, and insert the second stabilizing shaft 301 into the stabilizing hole 203. Insert the first positioning protrusion 102 into the fixing hole 202 and secure with external bolts.

[0042] Slide the sliding ring 4 and the sliding cylinder 5 onto the outer periphery of the support base 2 and fit the first limiting protrusion 401 and the second limiting protrusion 501 into the limiting notch 201. Place the diamond-shaped sliding block into the mounting hole 402 and engage it with the drive shaft 3. Then, the sliding ring 4 and the sliding cylinder 5 can be fixed together using the fixing piece 502.

[0043] The main body can be assembled by connecting the motor 6 and the gear box 7 to the rotating shaft base 1 and allowing the output shaft of the gear box 7 to pass through the rotating shaft base 1 and be fixedly connected to the drive shaft 3.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
