Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a joint massager motor sleeve. Background Technology

[0002] Joint massagers are widely used home and portable health care devices. They mainly use the rotation or vibration of a built-in motor to drive the massage head to act on human joints (such as knees, elbows, and shoulders) or muscle groups, so as to relieve soreness, promote blood circulation, relax muscles, and assist in rehabilitation.

[0003] With increasing health awareness, the market has placed higher demands on the comfort, quietness, and durability of joint massagers. Currently, joint massagers generally use miniature vibration motors as their core power source, and the high-frequency vibrations generated by the motor during operation are the basis for achieving the massage function.

[0004] The applicant discovered that in most joint massager motor sleeves, the motor and sleeve are a single, integrated mechanism. While this provides sufficient clamping force, it makes non-destructive disassembly difficult during after-sales maintenance and motor replacement, often requiring destructive removal, resulting in high maintenance costs and significant waste. Therefore, we have proposed a new type of joint massager motor sleeve. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber sleeve for a joint massager motor, which can solve the problem of high after-sales maintenance costs caused by the integrated design of the motor and the rubber sleeve mentioned in the background art.

The housing has a bowl-shaped cross-section. A sleeve body is detachably connected to one end of the housing away from the shaft. The housing and the shaft are fixed together by a fixing assembly. The fixing assembly includes a mounting cylinder. One end of the mounting cylinder has an opening for the shaft to be inserted into. One end of the shaft is fixed with a limiting slider. The inner wall of the opening has a limiting groove for the limiting slider to slide in. A strong spring is fixed to the inner wall of the opening. An annular fixing groove for the limiting slider to be limited is formed on the inner wall of the opening.

[0007] By adopting the above technical solution, it is possible to fix the installed shaft.

[0008] Preferably, the cross-section of the annular fixing groove is three-quarters annular, and the opening, the limiting slide groove, and the annular fixing groove are connected.

[0009] By adopting the above technical solution, the limiting slider can be limited.

[0010] Preferably, the bottom wall of the annular fixing groove is fixed with two symmetrically arranged hemispherical blocks, the hemispherical blocks are made of elastic plastic, and the bottom of the limiting slider is provided with a slot for the hemispherical blocks to engage.

[0011] By adopting the above technical solution, the limiting slider can be further fixed.

[0012] Preferably, the inner wall of the rubber sleeve body is fixed with a retaining edge, and the outer wall of the outer shell is provided with a mounting groove for fixing the retaining edge.

[0013] By adopting the above technical solution, the installation of the rubber sleeve body can be achieved.

[0014] Preferably, a buffer pad is installed between the outer shell and the rubber sleeve body, the buffer pad is fixedly connected to the outer side wall of the outer shell, and the outer side wall of the buffer pad is provided with elastic buffer ribs.

[0015] By adopting the above technical solution, the intensity of vibration can be improved.

[0016] Preferably, there are ten elastic buffer ribs, which are distributed in an equidistant ring.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0027] Please see Figures 1-4 The figure shows a joint massager motor sleeve, including a housing 1 and a shaft 101. The housing 1 has a bowl-shaped cross-section. The end of the housing 1 away from the shaft 101 is detachably connected to a sleeve body 102. The inner sidewall of the sleeve body 102 is fixed with a retaining edge 1021, and the outer sidewall of the housing 1 has a mounting groove 1022 for fixing the retaining edge 1021. The housing 1 and the shaft 101 are fixed together by a fixing component 2. The fixing component 2 includes a mounting cylinder 201, which is fixedly installed at the axial position of the inner sidewall of the housing 1. One end of the mounting cylinder 201 has an opening 2011 for the shaft 101 to be inserted into, and one end of the shaft 101 is fixed with a limiting slider 202. The inner sidewall of the opening 2011 has a limiting groove 2021 for the limiting slider 202 to slide. A strong spring 203 is fixedly provided on the inner side wall of the opening 2011. An annular fixing groove 204 is provided on the inner side wall of the opening 2011 for limiting the slider 202. The cross section of the annular fixing groove 204 is three-quarters of a circle. The opening 2011, the limiting groove 2021, and the annular fixing groove 204 are connected. Two symmetrically arranged hemispherical blocks 205 are fixedly provided on the bottom wall of the annular fixing groove 204. The hemispherical blocks 205 are made of elastic plastic. The bottom of the limiting slider 202 is provided with a slot 2051 for the hemispherical blocks 205 to engage. A buffer pad 3 is installed between the outer shell 1 and the rubber sleeve body 102. The buffer pad 3 is fixedly connected to the outer side wall of the outer shell 1. An elastic buffer rib 301 is fixedly provided on the outer side wall of the buffer pad 3. There are ten elastic buffer ribs 301, and the ten elastic buffer ribs 301 are distributed in an equidistant ring. When using the device, first install the outer casing 1. Insert one end of the shaft 101 into the opening 2011 at one end of the mounting cylinder 201, with the limiting slider 202 and the limiting groove 2021 in place. Then, one end of the shaft 101 abuts against one end of the power spring 203. As the shaft 101 gradually compresses the power spring 203, when the limiting slider 202 and the annular fixing groove 204 are on the same horizontal plane, rotate the outer casing 1 or the shaft 1 by 90 degrees. 01. During rotation, the limiting slider 202 abuts against the hemispherical locking block 205. After rotation, the hemispherical locking block 205 engages with the locking groove 2051, and the limiting slider 202 abuts against the inner wall of the hemispherical locking block 205. The elastic potential energy of the strong spring 203 pushes the shaft 101, ensuring the stability of the limiting slider 202 within the annular fixing groove 204. This, in turn, is achieved through the abutment between the limiting slider 202 and the annular fixing groove 204 in the fixing assembly 2. Next, with the engagement of the hemispherical locking block 205 and the locking slot 2051, the installation and fixation of the shaft 101 and the outer shell 1 are effectively realized. Furthermore, the detachable and quick connection between the outer shell 1 and the shaft 101 not only reduces the cost of later maintenance but also improves the practicality of the device during use. Then, the rubber sleeve body 102 is fitted onto the outer surface of the outer shell 1, and the elastic buffer rib 301 on one side of the buffer pad 3 abuts against the inner wall of the rubber sleeve body 102. The rubber sleeve body 102 is fixed by the elastic engagement of the locking edge 1021 at one end of the rubber sleeve body 102 and the mounting groove 1022 at one end of the outer shell 1. Then, the shaft 101 is driven by the vibration motor, which drives the outer shell 1 and the rubber sleeve body 102 to vibrate. The vibration force is buffered by the cooperation of the buffer pad 3 and the elastic buffer rib 301, thereby softening the vibration force generated by the massage chair and improving the user's comfort during use.
