Description
Technical field
The utility model relates to field of furniture, specifically a kind of armrests.
Background technology
The handrail of existing office chair is generally fixing, promptly can not regulate height can not adjusting angle, the office chair that has can be regulated height of armrests, but can not adjusting angle, this has just brought some inconvenience to the user, the user sometimes needs handrail sometimes not need handrail again, and so fixing handrail just can not satisfy all demands of user; When in smaller space, handrail can account for certain space, makes user's utilized space fewer.
The utility model content
The armrests that the utility model provides a kind of and regulates, flexibility is good, safe and reliable.
The utility model is achieved through the following technical solutions:
A kind of armrests comprises support, base and fixed block, and described base is provided with rotating shaft, described support is provided with bar and shaft hole, described shaft hole is passed in described rotating shaft, and described fixed block is connected with rotating shaft by screw, is provided with the elastic force positioner between described support and the fixed block.
Described elastic force positioner comprises spring and iron shot, described fixed block is provided with spring eye, the diameter of described spring and the diameter of iron shot are all less than the diameter of spring eye, and described spring diameter is less than the iron shot diameter, described spring one end is positioned in the spring eye, the described spring other end is placed iron shot, at the some iron shot grooves of being provided with in the radial direction of described support.
Described support is " L " type.
Be provided with four iron shot grooves in the radial direction at described support.
Described handrail also comprises trim, and described trim is connected with support by buckle.
The beneficial effect that the utility model brought is:
In the utility model, described handrail comprises support, base and fixed block, described base is provided with rotating shaft, described support is provided with bar and shaft hole, and described shaft hole is passed in described rotating shaft, and described fixed block is connected with rotating shaft by screw, described support can rotate around the axis, and then realized the purpose of handrail adjustable angle being fit to crowd more widely, satisfy user's multiple demand; Be provided with the elastic force positioner between described support and the fixed block, described elastic force positioner can play the purpose of handrail adjusting angle effectively, and the user is more laborsaving when regulating handrail, and can realize handrail multiposition location; Described elastic force positioner comprises spring and iron shot, and described fixed block is provided with spring eye, and described spring one end is positioned in the spring eye, the described spring other end is placed iron shot, described iron shot is at the effect lower compression spring of power, and it is suitable more sliding that handrail is rotated, and the user is more laborsaving; The diameter of described spring and the diameter of iron shot are all less than the diameter of spring eye, and described spring diameter is less than the iron shot diameter, so just spring and iron shot can be put into spring eye, spring and iron shot be carried out the position qualification, but must guarantee that iron shot partly exposes outside the spring eye; At the some iron shot grooves of being provided with in the radial direction of described support, when iron shot slipped in the different iron shot grooves, then handrail was in different positions, and then satisfied user's different demands; Described support is " L " type, makes the user more cosily by putting, and structure firm more, be more prone to realize; Described handrail also comprises trim, and described trim is connected with support by buckle, described trim be used to hide the inside of handrail more ugly structure, play effect attractive in appearance.

Fig. 4 is the structural representation of fixed block described in the utility model.
The label of component names correspondence is as follows among the figure:
1, support; 11, bar; 12, shaft hole; 13, iron shot groove; 2, base; 21, rotating shaft; 22, screw hole; 3, fixed block; 31, spring eye; 32, through hole; 4, screw; 5, spring; 6, iron shot; 7, trim.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Embodiment as armrests described in the utility model, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprise support 1, base 2 and fixed block 3, described base 2 is provided with rotating shaft 21, described support 1 is provided with bar 11 and shaft hole 12, described shaft hole 12 is passed in described rotating shaft 21, and described fixed block 3 is connected with rotating shaft 21 by screw 4, is provided with the elastic force positioner between described support 1 and the fixed block 3.Described support 1 can 21 rotate around the shaft, and then has realized the purpose of handrail adjustable angle being fit to crowd more widely, satisfies user's multiple demand; Described elastic force positioner can play the purpose of handrail adjusting angle effectively, and the user is more laborsaving when regulating handrail, and can realize handrail multiposition location.
In the present embodiment, described fixed block 3 is provided with two through holes 32, is respectively equipped with two screw holes 22 with through hole 32 corresponding sections in the described rotating shaft 21, and described screw 4 passes described through hole 32 and with screw hole 22 fixed block 3 is connected with rotating shaft 21.Described screw 4 is fixed relatively stable, and relatively firmly.
In the present embodiment, described elastic force positioner comprises spring 5 and iron shot 6, described fixed block 3 is provided with spring eye 31, the diameter of the diameter of described spring 5 and iron shot 6 is all less than the diameter of spring eye 31, and the diameter of described spring 5 is less than the diameter of iron shot 6, described spring 5 one ends are positioned in the spring eye 31, and described spring 5 other ends are placed iron shot 6, are provided with four iron shot grooves 13 in the radial direction at described support 1.Described iron shot 6 is at the effect lower compression spring 5 of power, and it is suitable more sliding that handrail is rotated, and the user is more laborsaving; Spring 5 and iron shot 6 are put into spring eye 31, spring 5 and iron shot 6 are carried out the position limit, but must guarantee that iron shot 6 parts expose outside the spring eye 31; Described four iron shot grooves 13 are used for the handrail location, and promptly handrail has four orientable positions.
In the present embodiment, described support 1 is " L " type.Described " L " type makes the user more cosily by putting, and structure firm more, be more prone to realize.
