Description
Technical field
The utility model relates to a kind of for adjusting leg height to obtain the regulating mechanism of balance support.
Background technique
Leg is arranged at desk, wardrobe, refrigerator, washing machine and a lot of large-scale household electrical appliances bottom, and many times four legs are not steadily difficult to mix up with mat.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and is arranged on leg, novel structure, the convenient regulating mechanism of adjusting leg height.
In order to solve above-mentioned technical problem to be solved, the utility model has adopted following technological scheme:
A leg height adjusting, comprising: be arranged on the support device of leg bottom, and be arranged in leg sidepiece one installation cavity and the hand controlling device being connected with support device; Described support device top is one longitudinally to stretch into the motion bar of leg bottom, and motion bar top arranges an angled end-face; Described hand controlling device comprises rocking arm, screw rod and pushing block; Described pushing block is positioned at installation cavity, and pushing block the inner is provided with the inclined thrust surface corresponding with motion bar top; Described screw flight is connected to the oral area of installation cavity, and the inner is stretched in installation cavity; The inner outer end that connects described pushing block of screw rod; Described rocking arm is hinged on the outer end of screw rod.
As preferably, described hand controlling device also comprises spring, and described spring is between screw rod the inner and pushing block outer end, and screw rod the inner connects the outer end of described pushing block by spring.
As preferably, described leg height adjusting also comprises: the round bump that is located at leg sidepiece; Described round bump periphery wall is provided with a plurality of latches; The middle part of described circular double wedge is communicated with installation cavity; Described rocking arm is provided with and described round bump phase magnetic the fastener that matches with described latch.
Adopted the leg height adjusting of technique scheme, hand controlling device position is in leg side, by hand controlling device, shakes rocking arm, can drive screw axially to movable in installation cavity and push pushing block.Because the inner is provided with inclined thrust surface, and the motion bar top on support device top is also provided with angled end-face, and inclined thrust surface and angled end-face coupling, when therefore axially promotion inclined thrust surface is transverse shifting inclined thrust surface, can be impelled the motion bar of longitudinal spacing to press down, thereby heighten leg; Otherwise, can recall to original height.This hand regulative mode completes the regulating mechanism that leg just regulates, novelty simple in structure not only, and also easy to adjust, using effect is good.
Accompanying drawing explanation
Fig. 1: the part section structural representation of a kind of state of the utility model embodiment.
The side structure schematic diagram of Fig. 2: Fig. 1.
Fig. 3: the part section structural representation of the utility model embodiment's another kind of state.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment:
A kind of leg height adjusting as shown in Figure 1, Figure 2 and Figure 3, this leg height adjusting comprise be arranged on leg 1 bottom support device, be arranged on the hand controlling device of leg 1 sidepiece and be located at the round bump 10 of leg 1 sidepiece.In order to install this leg height adjusting, leg 1 sidepiece is laterally provided with an installation cavity 11, leg 1 along bottom centre be longitudinally provided with can only be up and down movable span 12, movable span 12 upper ends are communicated with installation cavitys 11.Wherein:
Above-mentioned support device bottom is a pressing plate 3 for contacting with ground, and top is one by movable span 12, longitudinally to stretch into the motion bar 3 of leg 1 bottom, and motion bar 3 tops arrange an angled end-face 2a.Above-mentioned round bump 10 is fixed on leg 1 sidepiece, and best and leg sidepiece is connected as a single entity.Above-mentioned hand controlling device comprises rocking arm 7, screw rod 6, spring 5 and pushing block 4, and pushing block 4 is positioned at installation cavity 11, and pushing block 4 the inners are provided with the inclined thrust surface 4a corresponding with motion bar 3 tops, and pushing block 4 outer ends are burnishing surfaces.The inner sealing of installation cavity 11, outer end extends to the middle part of round bump 10, and gets through the external world, and the outer end oral area of installation cavity 11 is provided with internal thread.Above-mentioned screw rod 6 is threaded in the oral area of installation cavity 11, and screw rod 6 outer ends be in outside, the inner is stretched in installation cavity 11.Screw rod 6 the inners are also burnishing surfaces, and above-mentioned spring 5 is just pressed between screw rod 6 the inners and pushing block 4 outer ends by elasticity.Rocking arm 7 is in outside, and rocking arm 7 one end are hinged on the outer end of screw rod 6, and rocking arm 7 the other ends are also provided with a bending mouth matching with round bump 10 shapes.
Above-mentioned round bump 10 periphery walls are provided with a plurality of latches 101, in order to allow rocking arm 7 be locked between above-mentioned a plurality of latch 101, can not arbitrarily be changed, and the bending mouth inside portion of above-mentioned rocking arm 7 is provided with the fastener 71 matching with latch 101.The fastener 71 of above-mentioned rocking arm 7 can be with magnetic ferromagnetic material manufacture, and corresponding round bump 10 to adopt iron or the ferromagnetic material manufacture of phase magnetic, object be when not rotating rocking arm 7, can utilize magnetic to buckle between latch 101, realize spline.
During use, first, find the leg 1 that needs to adjust height, then pull out by rocking arm 7 outer ends of magnetic, make the fastener 71 on rocking arm 7 depart from latch 101; Then, the clockwise A direction of arrow of rocking arm 7 is shaken so that screw rod 6 inwardly advances along installation cavity 11 axial directions, Compress Spring 5 also drives pushing block 4 to promote.Finally, the inclined thrust surface 4a of pushing block 4 and angled end-face 2a, under the effect of promotion pressure, impel by the motion bar 2 of longitudinal spacing and press down, and make pressing plate 3 explore downward to ground, thereby heighten the stable main part of propping up of leg.Otherwise the reverse rocking arm 7 that shakes, recalls to original position.
