Description

Technical Field

[0001] This utility model relates to the field of massage mechanism technology, specifically a massage mechanism with an adjustable massage head width. Background Technology

[0002] The massage mechanism mainly consists of a motor and a massage stick. The motor drives the massage stick to rotate. When the rotating massage stick comes into contact with the skin, it can massage the skin and relax the muscles.

[0003] A massage mechanism and a massager using this mechanism, as disclosed in CN202236200U, involves placing a massage pillow over the neck with the massage head facing the neck, turning on the switch, and supplying power to the motor. The motor drives the transmission mechanism, which in turn drives the massage head to perform massage movements on the neck, promoting blood circulation and relaxing the neck muscles. Alternatively, a handheld massager can be used, where the massager is held in the hand with the massage head facing the area to be massaged (limbs, etc.), and the switch is turned on. The motor drives the transmission mechanism, which in turn drives the massage head to perform massage movements on the corresponding area, promoting blood circulation and relaxing the muscles. A back massager can also be used, where the massager is placed on a bed or chair back with the massage head facing the back area to be massaged, and the switch is turned on. The motor drives the transmission mechanism, which in turn drives the massage head to perform massage movements on the corresponding area, promoting blood circulation and relaxing the muscles. However, the following drawbacks still exist:

[0004] In actual use of the above device, although the massage head body can be rotated by a motor to perform massage, each person's physique is different, and because the massage head body is fixed, only one set of massage head bodies can provide an effective and comfortable massage when the two sets of massage head bodies are performing massage, resulting in poor massage effect of both sets of massage head bodies.

[0005] Therefore, we proposed a massage mechanism with an adjustable massage head width that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a massage mechanism with an adjustable massage head width, in order to solve the problem mentioned in the background art that the width of the massage head body in the current market cannot be adjusted.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a massage mechanism with an adjustable massage head width, comprising a mechanism housing and a massage head body, wherein the massage head body is disposed on the front end face of the mechanism housing;

[0008] Also includes:

[0009] The reciprocating lead screw has its left end connected to the inside of the mechanism housing via a bearing, and its right end extends out of the inside of the mechanism housing. Both ends of the reciprocating lead screw are threaded with sliders, which are slidably engaged inside the mechanism housing, and a rotating rod slides through the top of the slider.

[0010] The rotating rod is engaged with a bevel gear set, which is connected to the bevel gear set on the worm. The upper and lower ends of the worm are connected to the inside of the slider via bearings. The outer end of the worm meshes with a worm wheel, and the middle of the worm wheel is engaged with a driven rod. The top of the driven rod extends out of the front end of the slider and the core housing. The rear end of the driven rod is connected to the inside of the slider via a bearing, and the front end of the driven rod is connected to the rear end of the massage head body.

[0011] Preferably, a heat dissipation hole is provided in the middle of the front end face of the mechanism housing, and the interior of the heat dissipation hole is in contact with the surface of the motor inside the mechanism housing.

[0012] The above structural design allows the heat dissipation holes to conduct heat.

[0013] Preferably, the bevel gear set on the rotating rod is fitted into the groove above the slider, and the outer end of the rotating rod is connected to the inside of the slider through a bearing, and the inner end of the rotating rod is connected to the output end of the motor inside the mechanism housing.

[0014] The above structural design allows the slider to move normally.

[0015] Preferably, a pulley is rotatably provided at the rear end of the worm gear, and the pulley at the rear end of the worm gear fits inside the slider. There is a height difference between the bottom end of the driven rod on the worm gear and the groove in the middle of the slider. The height between the bottom end of the driven rod on the worm gear and the groove in the middle of the slider is equal to the height of the groove above the driven rod.

[0016] The above structural design allows the driven rod to move up and down inside the slider.

[0017] Preferably, the rear end of the slotted upper part of the driven rod engages with a limiting rod, and the rear end of the limiting rod is slidably engaged at the rear end of the movement housing groove.

[0018] The above structural design allows the driven rod to be raised and lowered.

[0019] Preferably, the reciprocating lead screw is provided with two sets of threads, and the two sets of threads on the reciprocating lead screw are arranged in opposite directions.

[0020] The above structural design allows the two sets of sliders to move in opposite positions.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the adjustable massage head mechanism allows the massage head body to have a tapping function; the width between the two sets of sliders can be adjusted by rotating the reciprocating screw; and the limiting rod limits the driven rod, allowing the massage head body to have a telescopic function while rotating. The specific details are as follows:

[0022] Equipped with a reciprocating lead screw, rotating the reciprocating lead screw causes two sets of sliders to move in opposite directions, thereby causing the sliders to move the massage head body synchronously. This allows the width between the two sets of massage head bodies to be adjusted to meet the needs of different people.

[0023] A limit rod is installed. The rotation of the worm gear drives the driven rod to rotate, which in turn drives the massage head body to rotate. As the driven rod rotates, it is limited by the limit rod, which allows the limit rod to reciprocate up and down. This allows the limit rod to reciprocate the massage head body, enabling the massage head body to extend and retract while rotating, thus improving the usability of the massage head body.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a massage mechanism with an adjustable massage head width, including a mechanism housing 1 and a massage head body 4. The massage head body 4 is provided on the front end face of the mechanism housing 1. It also includes: a reciprocating lead screw 3, the left end of which is connected to the inside of the mechanism housing 1 through a bearing. The reciprocating lead screw 3 is provided with two sets of threads, and the two sets of threads on the reciprocating lead screw 3 are arranged in opposite directions. The right end of the reciprocating lead screw 3 extends out of the inside of the mechanism housing 1. Both ends of the reciprocating lead screw 3 are threadedly connected to sliders 6. The sliders 6 are slidably engaged inside the mechanism housing 1. A heat dissipation hole 2 is provided in the middle of the front end face of the mechanism housing 1. The inside of the heat dissipation hole 2 is in contact with the surface of the motor inside the mechanism housing 1. A rotating rod 7 is slidably passed through the top of the slider 6.

[0032] refer to Figures 1 to 3 When it is necessary to adjust the massage head body 4, the reciprocating screw 3 is rotated, which causes the slider 6 to move. Since the two sets of threads on the reciprocating screw 3 are set in opposite directions, the rotation of the reciprocating screw 3 can cause the two sets of sliders 6 to move in opposite positions. The movement of the sliders 6 will cause the bevel gear set 8 on the rotating rod 7 to slide on the rotating rod 7, thereby causing the sliders 6 to move the massage head body 4, and then the width between the two sets of massage head bodies 4 is adjusted. After the two sets of massage head bodies 4 are adjusted to the appropriate position, the motor is started.

[0033] A rotating rod 7 is engaged with a bevel gear set 8. The bevel gear set 8 on the rotating rod 7 is fitted into a groove above the slider 6, and the outer end of the rotating rod 7 is connected to the inside of the slider 6 via a bearing. The inner end of the rotating rod 7 is connected to the output end of the motor inside the mechanism housing 1. The bevel gear set 8 on the rotating rod 7 is connected to the bevel gear set 8 on the worm 9, and the upper and lower ends of the worm 9 are connected to the inside of the slider 6 via bearings. The outer end of the worm 9 meshes with a worm wheel 10, and a driven rod 11 is slidably engaged in the middle of the worm wheel 10. A pulley is rotatably mounted at the rear end of the worm wheel 10. The pulley fits inside the slider 6, and there is a height between the bottom end of the driven rod 11 on the worm gear 10 and the groove in the middle of the slider 6. The height between the bottom end of the driven rod 11 on the worm gear 10 and the groove in the middle of the slider 6 is equal to the height of the slot above the driven rod 11. The rear end of the slot above the driven rod 11 engages with the limiting rod 5, and the rear end of the limiting rod 5 is slidably engaged at the rear end of the groove in the mechanism housing 1. The top of the driven rod 11 extends out of the front end of the slider 6 and the mechanism housing 1. The rear end of the driven rod 11 is connected to the inside of the slider 6 through a bearing, and the front end of the driven rod 11 is connected to the rear end of the massage head body 4.

[0034] refer to Figures 1 to 5 The output of the motor rotates, causing the rotating rod 7 to rotate. The rotating rod 7 then drives the worm gear 9 to rotate via the bevel gear set 8. The worm gear 9 then drives the worm wheel 10 to rotate, which in turn drives the driven rod 11 to rotate. The driven rod 11 then drives the massage head body 4 to rotate. When the driven rod 11 rotates, it is limited by the limit rod 5, allowing the driven rod 11 to reciprocate up and down. This allows the driven rod 11 to drive the massage head body 4 to rotate while also moving up and down, thereby improving the massage effect of the massage head body 4.

[0035] Working principle: When using this massage mechanism with an adjustable massage head width, first, refer to... Figures 1 to 3 When it is necessary to adjust the massage head body 4, the reciprocating screw 3 is rotated, which in turn drives the two sets of sliders 6 to move in opposite positions, thereby causing the sliders 6 to move the massage head body 4, and thus adjusting the width between the two sets of massage head bodies 4.

[0036] refer to Figures 1 to 5 The output of the motor rotates, causing the rotating rod 7 to rotate. Then, the rotating rod 7 drives the worm gear 9 to rotate through the bevel gear set 8. This causes the driven rod 11 to drive the massage head body 4 to rotate. The driven rod 11 is limited by the limit rod 5, so that it can drive the massage head body 4 to rotate and also move up and down, thereby improving the massage effect of the massage head body 4.

[0037] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
