DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme of the utility model carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the figure to the utility model embodiment carries out further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, instead of all the embodiments, only to explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belongs to the scope of the protection of the utility model.

[0023] Embodiment one, please refer to Figures 1-5 The utility model provides a kind of technical scheme: a massage cushion with waist support structure, comprising: installation bottom plate 1 and connecting frame 4.

[0024] Specifically, flexible protective cover 2 is arranged on the front surface of installation bottom plate 1, elastic filler 3 is filled between flexible protective cover 2 and installation bottom plate 1, the surface of flexible protective cover 2 is provided with a plurality of evenly distributed massage convex points 21, massage convex points 21 are TPE massage balls, the surface of flexible protective cover 2 is arc structure, can adapt to the waist of user, when patient leans on the surface of flexible protective cover 2, massage convex points 21 can massage the acupoint of the waist of user, elastic filler 3 is made of flexible silica gel material, elastic filler 3 itself has elasticity, can restore deformation in time after being extruded;

[0025] Secondly, two strip-shaped through slots 12 that are a group are opened on the surface of installation bottom plate 1, two strip-shaped through slots 12 are mutually parallel and vertically arranged, short rack 11 is fixedly arranged on the back surface of installation bottom plate 1, and short rack 11 is located between two strip-shaped through slots 12, and the length dimension of short rack 11 is one third of the vertical dimension of installation bottom plate 1.

[0026] Further, hollow square tube 5 is fixed on the surface of connecting frame 4, both sides of hollow square tube 5 are located at both sides of installation bottom plate 1 respectively, and the side wall of hollow square tube 5 is slidingly installed in the inner cavity of strip-shaped through slot 12, the vertical length dimension of connecting frame 4 and hollow square tube 5 is consistent, and both are two thirds of the vertical dimension of installation bottom plate 1, Figure 2 And Figure 5As shown, the connecting frame 4 and the mounting bottom plate 1 can slide relative to each other in the vertical direction by a certain distance, and the connecting frame 4 can also move towards or away from the mounting bottom plate 1 within a certain distance range. A long rack 51 corresponding to the short rack 11 is arranged on the inner side wall of the hollow square tube 5. The long rack 51 and the short rack 11 are left with a gap. The connecting frame 4 is fixed to the seat. When the mounting bottom plate 1 moves away from the connecting frame 4, the long rack 51 and the short rack 11 are separated from each other. The user can easily adjust the height position of the mounting bottom plate 1. Then the user leans on the surface of the flexible protective cover 2. The elastic filler 3 is compressed and drives the mounting bottom plate 1 to move towards the connecting frame 4. At this time, the long rack 51 and the short rack 11 are engaged with each other, so as to position the vertical relative movement between the mounting bottom plate 1 and the connecting frame 4. That is, the mounting bottom plate 1 can remain stable and will not move downward due to its own gravity or the pressure of the user. The greater the pressure of the user on the mounting bottom plate 1, the tighter the engagement between the long rack 51 and the short rack 11, and the mounting bottom plate 1 is less likely to move downward.

[0027] In order to install the connecting frame 4, the application also has a binding rope 41 arranged at the edge of the connecting frame 4, and a bonding layer 54 arranged on the back of the hollow square tube 5. The binding rope 41 can be used to tightly fix the connecting frame 4 to the seat. The bonding layer 54 is a magic tape. The magic tape on the bonding layer 54 is fixed, and the magic tape on the seat is sewn and fixed. The connecting frame 4 is fixed to the surface of the seat by the magic tape, and the tight binding of the binding rope 41 can effectively prevent the connecting frame 4 from moving downward. In addition, based on solid wood seats or metal frame seats, the connecting frame 4 can also be fixed to the seat by the bolt connection structure known in the prior art. Here, no longer described.

[0028] In order to facilitate the user to easily adjust the height position of the device, the application also has a flange 52 fixed on the front surface of the hollow square tube 5, and the flange 52 is attached to the front surface of the mounting bottom plate 1. The surface of the flange 52 and the front surface of the mounting bottom plate 1 are respectively fixed with a magnet piece 53 and a metal piece 13. When the user does not lean on the device, the attractive force between the magnet piece 53 and the metal piece 13 can drive the mounting bottom plate 1 and the connecting frame 4 to move away from each other, that is, the long rack 51 and the short rack 11 can move away from each other, thereby facilitating the user to easily adjust the height position of the device.

[0029] In order to coat the elastic filler 3, the short rack 11, the strip-shaped through slot 12 and the hollow square tube 5 of the application are provided with two groups of horizontal two-end symmetrical distribution on the mounting base plate 1, the long rack 51 in the two groups of short racks 11 and the two groups of hollow square tubes 5 are one-to-one corresponding, which can improve the stability of the positioning of the mounting base plate 1, the edge of the flexible protective cover 2 is fixedly connected with the edge of the mounting base plate 1, as shown in Figure 2 After the flexible protective cover 2 is fixedly connected with the mounting base plate 1, the flexible protective cover 2 can wrap the elastic filler 3, so that the elastic filler 3 is prevented from falling off.

[0030] In order to avoid the extrusion force of the waist of the user on the hollow square tube 5, the application also has an isolation plate 6 arranged on the front outer side of the mounting base plate 1, a support strip plate 61 is fixedly arranged between the isolation plate 6 and the mounting base plate 1, the surface of the isolation plate 6 is adhesively fixed with the elastic filler 3, the arrangement of the isolation plate 6 can separate the elastic filler 3 from part of the surface of the mounting base plate 1, so that the hollow square tube 5 and the flange 52 are not blocked by the elastic filler 3 when the connecting frame 4 moves close to the mounting base plate 1, thereby avoiding the extrusion force of the waist of the user on the flange 52, so that the connecting frame 4 and the mounting base plate 1 are prevented from moving away.

[0031] Although the embodiments of the application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the application, the scope of the application is defined by the appended claims and their equivalents.
