Abstract
The utility model relates to a clamping structure for a handrail of a massage chair. The clamping structure comprises a handrail mounting base which is fixed on a massage chair skeleton; a mounting slot for mounting a handrail fastener is arranged on the handrail mounting base; an arc concave surface is arranged on the bottom surface of the mounting slot; and a minimal distance between two side walls of the mounting slot is less than a diameter of the arc concave surface. According to the clamping structure provided by the utility model, the mounting slot on the handrail mounting base is designed as a structure with the two side walls being opposite bulges and the minimal distance between the bulges is less than the diameter of the bottom surface of the mounting slot; when the handrail fastener is mounted, a bearing or bolt passes through the mounting slot, is jointed with the bottom surface of the mounting slot and is fastened by using a nut; and the distance between the two side walls of the mounting slot is smaller, so that the bearing or bolt does not sideslip even if the nut is loosened, and the fastening between the handrail and the massage chair skeleton is increased.
Description
Technical field
The utility model relates to physical therapy device component technology field, relates in particular to a kind of massage chair handrail interface arrangment.
Background technique
The massage chair handrail interface arrangment is that armrest skeleton and other auxiliary skeleton together are fastened on the massage chair skeleton by bearing or bolt assembly for the link that connects between armrest skeleton and the massage chair skeleton.The massage chair handrail interface arrangment comprises armrest mounting seat and handrail fastening piece, and the handrail fastening piece is general bearing or bolt assembly, and an end of handrail fastening piece is fastening by the mounting groove on the armrest mounting seat, and the other end is connected with armrest skeleton.In conventional art, mounting groove on the armrest mounting seat is made of the straight wall that circular arc concave bottom surface and two is tangential on circular arc, when using this kind massage chair, if the phenomenons such as lax appear in the handrail fastening piece, very easily cause handrail fastening piece integral body and armrest skeleton to break away from from mounting groove, soundness between armrest skeleton and the armrest mounting seat is reduced, and then reduced the soundness between armrest skeleton and the massage chair skeleton.
Summary of the invention
Technical problem to be solved in the utility model is the problems referred to above that exist for the mounting groove on the existing massage chair handrail fitting seat, and the massage chair handrail interface arrangment that a kind of fastening performance is good, be difficult for lax disengaging is provided.
For addressing the above problem, the technical solution of the utility model is:
A kind of massage chair handrail interface arrangment, comprise the armrest mounting seat that is fixed on the massage chair skeleton, described armrest mounting seat is provided with one for the mounting groove that the handrail fastening piece is installed, the bottom surface of described mounting groove is an arc-shaped concave, and the minimum between described mounting groove two side is opened apart from the diameter less than arc-shaped concave.
Preferably, the two side of described mounting groove is two relatively protruding convex surfaces, and the spacing of convex surface and convex surface is less than the diameter of arc-shaped concave.
Preferably, the joint of the bottom surface of described mounting groove and two side is the smooth transition curved surface.
Be compared to prior art, massage chair handrail interface arrangment of the present utility model is designed to the relatively structure of projection of two side with the mounting groove on the armrest mounting seat, and the minimum separable of projection and projection is less than the diameter of the bottom surface of mounting groove; When the handrail fastening piece is installed, make bearing or bolt pass mounting groove, and the bottom surface of applying mounting groove, rear by fastening nuts, owing to opening apart from less of mounting groove two side, even nut is lax, bearing or bolt can not break away out, have increased the tightness between handrail and the massage chair skeleton.
Description of drawings
Fig. 1 is the decomposition texture schematic representation of the utility model massage chair handrail interface arrangment.
Fig. 2 is the perspective view of the utility model massage chair handrail interface arrangment.
Embodiment
Further describe the utility model below in conjunction with drawings and Examples, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1-2, massage chair handrail interface arrangment of the present utility model comprises armrest mounting seat 1 and the handrail fastening piece that is fixed on the massage chair skeleton.Described armrest mounting seat 1 is " U " font, is extended with mountion plate 102 on " U " font upper-end surface of armrest mounting seat 1, and described mountion plate 102 is provided with some mounting holes 101, and described mounting hole 101 is used for connecting massage chair skeleton and armrest mounting seat 1.Described handrail fastening piece can be bearing or bolt assembly, describes in detail as an example of bolt assembly example in the utility model, and described handrail fastening piece is the assembly of bolt 2 and nut 3, and an end of bolt 2 is connected with nut 3, and the other end links to each other with handrail side panel axle 201.
" U " font bottom surface of described armrest mounting seat 1 is provided with one for the mounting groove 4 that the handrail fastening piece is installed, the bottom surface of described mounting groove 4 is an arc-shaped concave 401, and the minimum that two sidewalls of described mounting groove 4 are 402 is opened apart from the diameter less than arc-shaped concave 401.Two sidewalls 402 of described mounting groove 4 are two relatively protruding convex surfaces, and the minimum separable of convex surface and convex surface is less than the diameter of arc-shaped concave 401, and wherein arc-shaped concave 401 is major arc.The joint of the bottom surface of described mounting groove 4 and two side 402 is the smooth transition curved surface.When the handrail fastening piece is installed, make bolt 2 pass mounting groove 4, and the bottom surface of applying mounting groove 4, rear fastening by nut 3, because the opening apart from the less of two side 402 of mounting groove 4, even nut 3 is lax, bolt 2 can not break away out, has increased the tightness between handrail and the massage chair skeleton.
