Abstract

The utility model relates to a feet adjusting device for furniture, which mainly comprises an adjusting knob, a supporting pad, a screw, etc. The feet adjusting device for furniture is characterized in that the screw is integrally connected with the adjusting knob in the way of coating; a clamping end on the lower end of the adjusting knob is clamped and threaded into a clamping hole on the upper end of the supporting pad. By using an inner hexagonal hole on the upper end of the screw and the adjusting knob, the feet adjusting device for furniture can provide two adjusting modes. In addition, the supporting part can be stock to the ground and does not make synchronous rotation with the adjusting knob. By using nylon materials, the utility model can reduce friction to achieve the purpose of adjustment labor saving and prevent the ground (blanket) from damaging caused by the rotation of the supporting pad.

Description

Means for adjusting feet of furniture

The utility model relates to a kind of footing adjusting device, is meant a kind of two ends, screen bottom that are arranged on especially, can adjust the height and the symmetric design of screen assembling.The utility model rapid operation also can reduce and adjust the destruction of pin to ground.

General common footing adjusting device as illustrated in fig. 1 and 2, the bottom of adjusting pin 1 is a discoid support pads 11, connects solid a screw 13, screw 13 bottoms and support pads 11 solid weldings one nut 12 on this support pads 11.This adjustment pin 1 commonly used places in the nut 15 of solid welding on the lower frame sheet 14 that is screwed together in the screen bottom, when adjusting its nut 12 of adjusting pin 1, the height of screen is conformed to the screen of collocation mutually.

Learn by above-mentioned known product, the fine setting of screen height is that the nut 15 of temporarily transferring solid welding on screw of whole pin 1 13 and the screen lower frame sheet 14 is screwed, and then adjust that support pads 11 upper limb nuts 12 finish, because screw 13, nut 12 and support pads 11 link structure for one, so when adjusting its nut 12, this support pads 11 is also together with the rotation start.Yet well known, the weight of every fan screen is all born by the adjustment pin 1 of bottom two ends, when desire is adjusted one of them end adjustment pin 1, must take suitable strength, could adjust by rotating screw cap 12; And, support pads 11 links for one with nut 12 and screw 13, so also turn synchronously of support pads 11, because the weight pressure-bearing of screen, make support pads 11 quite big with the frictional force on ground, if screen is adjusted pin 1 turn adjustment on carpet, then tend to destroy carpet, use quite inconvenience.

Primary and foremost purpose of the present utility model is to overcome above-mentioned shortcoming, and a kind of improved footing adjusting device is provided, and makes the Height Adjustment of screen laborsaving, makes things convenient for and increase flexibility.

Secondary objective of the present utility model is that to make support pads be asynchronous start with adjusting screw, to keep the complete attractive in appearance of carpet.

The footing adjusting device that the utility model proposes mainly comprises: adjust members such as knob, support pads, screw, described screw upper end is an inner hexagonal hole, this adjustment knob is coated on the screw lower end, and adjust the rack saw shape concave convex texture conduit for being equally spaced on every side of knob, this is adjusted knob lower end and protrudes the fastening end that a circle is buckled shape; In the form of annular discs and the upper end centre of support pads is a connecting hole, this support pads lower surface is the dog of concentric circles, it is characterized in that: borrowing screw and adjusting knob is that one coats binding, and the fastening end buckle of adjusting the knob lower end is placed through in the connecting hole of support pads upper end, this screw places in the screw piece that is screwed together in the screen lower frame, utilize the inner hexagonal hole of screw upper end and adjust knob, two kinds of adjustment modes can be provided, moreover, be the movable structure of turn separately between support pads and adjustment knob, and utilize nylon material to reduce friction, reach laborsaving adjustment and keep the purpose that ground (blanket) is not destroyed.

Details are as follows to the utility model below in conjunction with preferred embodiment and accompanying drawing, among the figure:

Fig. 1 is existing D structure figure with product;

Fig. 2 is the enforcement view of known product;

Fig. 3 is D structure figure of the present utility model;

Fig. 4 is a combination schematic diagram of the present utility model;

Fig. 5 is a composite construction generalized section of the present utility model.

Footing adjusting device such as Fig. 3 that the utility model provides, shown in 4 and 5, this footing adjusting device 2 comprises: adjust knob 21, main members such as support pads 22, screw 23.Known to diagram, screw 33 upper ends in the utility model are an inner hexagonal hole 231, the bottom combines fixing with adjustment knob 21, this adjustment knob 21 is coated on screw 23 lower ends with injection molding, and adjusts the rack saw shape concave convex texture conduit 211 for being equally spaced on every side of knob 21, adjusts knob 21 lower ends and protrudes the fastening end 212 that a circle is buckled shape, in addition, support pads 22 is in the form of annular discs, and the upper end centre is a connecting hole 221, and these support pads 22 lower surfaces are dogs 220 of concentric circles.By shown in Figure 4, the screw 23 on the utility model top and adjustment knob 21 are that one links, and fastening end 212 buckles of temporarily transferring whole knob 21 lower ends are placed through in the connecting hole 221 of support pads upper end.

As shown in Figure 5, screw 23 in the utility model places in the screw piece 25 that is bolted in general screen lower frame 24, during adjustment, the relative start of borrowing an Allen wrench turn screw 23 can reach screw 23 and screw piece 25 by the inner hexagonal hole of screw upper end is with the height of adjustment screen; Another adjustment mode is to temporarily transfer whole knob 21 directly to adjust with hand-screw is moving.From the above, structural feature of the present utility model is that screw 23 is that one links with adjustment knob 21, and the fastening end 212 of temporarily transferring whole knob 21 bottoms is snapped in the connecting hole 221 of support pads 22, when adjusting screw 23 or adjusting knob 21, support pads 22 still can be maintained fixed not turn, adjusts integrality laborsaving and the maintenance carpet.

In sum, the utility model is overcome improvement at the shortcoming of prior art products, and it is simple and practical.

Should be understood that above-mentioned disclosed preferred embodiment only is for structure of the present utility model is described, in not breaking away from claims of the present utility model institute restricted portion, can make various variations.
