Technical Field

The utility model belongs to the technical field of water supply and drainage heating ventilation, and particularly relates to a reserved sleeve device for water supply and drainage heating ventilation in a building.

Background

With the progress and development of society, it is a very necessary and important step to warm logical reservation of plumbing in the building process, whether the success of reservation influences the normal operating of follow-up construction process, present sleeve pipe most uses the PVC sleeve pipe, in order to guarantee the quality of reserving the entrance to a cave, reserve the sleeve pipe and all must have certain intensity, all thicken the inner wall of PVC sleeve pipe, just so improved construction cost, and changed original sheathed tube size, be unfavorable for subsequent pipeline butt joint.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a water supply and drainage heating and ventilation reserved sleeve device for a building, which aims to solve the problem that the butt joint of subsequent pipelines is not facilitated due to the thickening of the inner wall of a PVC sleeve in the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a warm logical sleeve pipe device of reserving of plumbing in room, includes the PVC sleeve pipe, PVC sheathed tube is built-in to be equipped with the support cylinder, be equipped with four through-holes on the support cylinder, the support cylinder upper end is equipped with the screw hole, the internal cylinder groove that is equipped with of support column, four the through-hole is linked together with the cylinder groove, the built-in trapezoidal movable block that is equipped with of through-hole, four the backup pad has all been installed near PVC sheathed tube one end to trapezoidal movable block, the support cylinder facial make-up is equipped with reset spring, the reset spring other end is connected with the backup pad, the built-in round platform that is equipped with in cylinder groove, the threaded rod has been installed to the round platform upper end, threaded rod and screw hole threaded connection.

Preferably, the upper end of the threaded rod is provided with a rotating handle.

Preferably, the upper end and the lower end of the movable block are both smooth.

Preferably, one side of the supporting plate close to the PVC sleeve is provided with a rubber strip.

Preferably, two handles are arranged on the supporting column body.

Compared with the prior art, the utility model has the beneficial effects that: through backup pad and the sheathed tube inner wall contact of PVC, improve the sheathed tube intensity of PVC, need not carry out the inner wall thickening again, make things convenient for subsequent pipeline butt joint and saved construction cost, through having installed the rubber strip, damage when reducing backup pad and the contact of PVC pipe box inner wall, reuse can be taken out to this device.
