Description

Technical Field

[0001] The utility model relates to the field of massage devices, in particular to a hand massager. Background Art

[0002] With the improvement of people's attention to health, massagers have gradually been widely used in various families. According to different massage parts, the shapes of various massagers are different. Among them, the hand massager is a small massager, mainly for massaging the palmar muscles on the palm, which is beneficial to promoting the relaxation of hand muscles and the flexibility exercise of various parts of the hand, and is beneficial to promoting blood circulation in the hand.

[0003] There are many existing roller massagers on the market, mainly including a central shaft and a roller. The roller is provided with a hollow interior. When installing the massager, the roller is sleeved on the central shaft, and then both ends of the central shaft are installed on other components of the massager through a hook structure, screws or other devices. The installation process is very cumbersome, especially when a massager has multiple central shafts, the installation process becomes even more cumbersome; in addition, in this kind of massager, the central shaft is produced and manufactured separately, which increases the number of parts and the production and manufacturing cost is higher. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a hand massager, which solves the problems of cumbersome installation process and high manufacturing cost of the massager.

[0005] The technical solution adopted by the utility model is: a hand massager, including a frame body and a roller. The roller is densely provided with massage protrusions. The frame body includes a central shaft and a connecting block. The number of the central shafts is at least two, and the number of the connecting blocks is two and integrally formed at both ends of each central shaft; the roller is correspondingly rotatably connected to the central shaft. The roller includes a first half cylinder and a second half cylinder. A first protrusion is arranged on the first half cylinder, and a second clamping groove is arranged on the second half cylinder. The first protrusion and the second clamping groove are detachably connected to each other.

[0006] Through the above technical solution, the user can complete the installation of the roller relative to the central shaft by clamping the first half cylinder and the second half cylinder through the first protrusion and the second clamping groove. During this installation process, there is no need to perform installation operations on the central shaft, and the installation process is more convenient and fast; in this massager, each central shaft and two connecting blocks are integrally formed, effectively reducing the number of parts of the whole massager, and reducing the production cost and production difficulty.

[0007] Furthermore, a first clamping groove is arranged on the first half cylinder, and a second protrusion is arranged on the second half cylinder. The second protrusion and the first clamping groove are detachably connected.

[0008] Through the above technical solution, the first half cylinder is provided with a first protrusion and a first card slot at the same time, and the second half cylinder is provided with a second protrusion and a second card slot at the same time, making the force more uniform in the rotation direction of the drum, avoiding the situation that the first protrusion or the second protrusion breaks during use, and prolonging the service life.

[0010] Through the above technical solution, the first half cylinder and the second half cylinder can share a set of molds during production, further reducing the production cost.

[0011] Furthermore, at least one first protrusion is arranged on each of the two side edges of the first half cylinder, at least one first card slot is arranged on each of the two side edges of the first half cylinder, at least one second protrusion is arranged on each of the two side edges of the second half cylinder, and at least one second card slot is arranged on each of the two side edges of the second half cylinder.

[0012] Through the above technical solution, the first protrusion and the first card slot on the first half cylinder are arranged in a staggered manner, and the second protrusion and the second card slot on the second half cylinder are arranged in a staggered manner, making the connection between the first half shell and the second half shell more stable.

[0013] Furthermore, a first rib and a first strip-shaped depression are respectively arranged on the two side edges of the first half cylinder, and a second rib and a second strip-shaped depression are respectively arranged on the two side edges of the second half cylinder; the first rib and the second strip-shaped depression are fitted, and the second rib and the first strip-shaped depression are fitted.

[0014] Through the above technical solution, the first rib and the second rib can effectively share the lateral force acting on the first protrusion and the second protrusion, avoiding the situation that the first protrusion and the second protrusion are bent or even broken during use, and making the service life longer.

[0015] Furthermore, an annular concave surface is arranged on the surface of the drum, and a plurality of the annular concave surfaces are arranged in the length direction of the drum.

[0016] Through the above technical solution, the annular concave surface can avoid the user's fingers. When the human hand holds the massager, the annular concave surface corresponds to the human fingers, making the shape of the massager more ergonomic and more comfortable to use.

[0017] Furthermore, it further includes balls. An arc-shaped mounting position is provided on the connecting block. A housing is detachably arranged on the connecting block. A circular avoidance hole is provided on the housing. The diameter of the circular avoidance hole is smaller than the diameter of the balls. The balls are rotatably connected to the arc-shaped mounting position and part of the balls are exposed through the circular avoidance hole.

[0018] Through the above technical solution, the user can also use the balls to massage parts other than the human hand, and the massage function is more abundant.

[0019] Furthermore, a clamping block is provided on the connecting block, and a clamping hole is provided on the housing. Both the clamping block and the clamping hole are strip-shaped and are detachably connected to each other. The clamping block is provided with an inclined surface obliquely facing outward.

[0020] Through the above technical solution, the structures of the clamping block and the clamping hole are simple and easy to install. The setting of the inclined surface makes the installation and connection of the clamping block and the clamping hole easier; both the clamping block and the clamping hole are strip-shaped, so that there are more contact positions after the clamping block and the clamping hole are connected, and the connection is more firm.

[0021] Furthermore, the number of the housings is two, and the two housings are respectively connected to two corresponding connecting blocks. The number of the balls correspondingly connected to a single connecting block is at least two.

[0022] Through the above technical solution, both ends of the massager can use the balls for massage, making the use of the massager more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
