Abstract

A four-corner circle self-fixing type wall-embedded concealed-installation bottom box can be fixed in wall circular holes. Four corners of the wall-embedded concealed-installation bottom box are circular. A symmetric reverse-direction self tapping screw is respectively arranged in the four circular corners of the bottom box. Rubber pads opposite to positions of the reverse-direction self tapping screws are mounted on external bottom of the circular corners of the bottom box. By screwing the reverse-direction self tapping screws and ejecting the rubber pads disposed on the external of the circular corners, rubber pads are contacted with and tightly supported on inner walls of the circular holes, and an effect that the bottom box and the inner walls of the circular holes generate reaction force is achieved.

Description

Four jiaos of circular self-hards enter the wall concealed bottom and close

Affiliated technical field

The utility model relates to enter wall concealed installation method, especially its four jiaos of circle of a kind of indoor electric appliance 86 end syzygy row and can oneself consolidate in the circular hole that the wall body is held successfully in advance.

Background technology

At present, it is square or rectangular that known 86 serial concealed bottoms close, such end, be installed close the pit that need to go out at wall square or rectangular with it by the hand excavation, then with cement mortar or in pit again boring beat glue follow closely the end, closed fixing, marquis when cement mortar has been done, make easily the end and close and come off, such installation method the end occurs easily and closes asymmetric not parallelly, easily makes technological problems.In addition, in that to install operating efficiency not high yet, what a, be installed such end close, fix end contract by digging pit to 15 minutes consuming time, so just made very large artificial waves not.

Summary of the invention

Enter the wall concealed bottom and be combined in the deficiency of installing in order to overcome current 86 series, the utility model provides a kind of 86 series to enter the wall concealed bottom and closes, and four angles that close at this end are that circle can be from solid in the circular hole of wall body.

The utility model solves the technical scheme that its installation method adopts: four angles that profile is closed at the end are circular, in four fillets bottoms of closing the end of at, respectively be provided with a symmetrical reverse self-tapping screw that bottom close at the end, becomes miter angle, in outside, four fillet bottoms, position with reverse self tapping sieve silk symmetry, respectively be provided with the rectangle rubber cushion, by tightening four reverse self-tapping screws of bottom, rubber cushion is separately ejected outward, rubber cushion is contacted with the circular hole wall to be held out against, reach and the circular hole wall produces reaction force, thereby play the effect of closing the fixing end.

The beneficial effects of the utility model are: improved the installation rate that 86 concealed bottoms close, improved technique and the quality of closing installation in the end, reduced in a large number artificial installation cost.A end of the present utility model contract is installed 3 minutes consuming time, is reached saving, the easy-to-install effect saves time.

In Fig. 5: the 1st, self-tapping screw, the 2nd, rubber cushion.

Embodiment

Put into pre-drilled circular hole with closing at the bottom of the utility model, adjust the degree of depth and the depth of parallelism, then tighten self-tapping screw (1) among Fig. 5 and rubber cushion (2) is advanced to the circular-hole internal-wall direction hold out against, close and hole wall generation reaction force at the end like this, accomplishes the effect that close at the fixing end.

Claims

1. one kind four jiaos circular self-hards enter the wall concealed bottom and close, and it can close self-retaining the end of with in the pre-drilled circular hole of wall body, and it is characterized in that: four angles that close at the end are circular.

2. four jiaos of circular self-hards according to claim 1 enter the wall concealed bottom and close, and it is characterized in that: four fillets bottoms that close at the end respectively are provided with a symmetrical reverse self-tapping screw { 1} who becomes miter angle bottom close at the end.

3. four jiaos of circular self-hards according to claim 1 enter the wall concealed bottom and close, and it is characterized in that: the outside of closing the fillet bottom, the end is provided with the rubber cushion { 2} with reverse self-tapping screw position symmetry.
