Description

Telescopic pipe convenient to disassemble and assemble for dust collector

Technical Field

The utility model relates to a flexible pipe for dust catcher convenient to dismantle.

Background

The telescopic tube is generally used for being connected between a dust collector and a floor brush, and plays a role of an air flow and dust channel, and the telescopic function of the telescopic tube is more beneficial to the operation of a user. The telescopic pipe generally comprises an outer pipe and an inner pipe, wherein one end of the inner pipe is inserted into the outer pipe, and a limiting structure is required to be arranged between the outer pipe and the inner pipe for preventing the outer pipe from being separated from the inner pipe, but due to the existence of the limiting structure, the disassembly between the outer pipe and the inner pipe is very inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a flexible pipe for dust catcher convenient to dismantle, its is rational in infrastructure to the mutual dismantlement of outer tube and inner tube has been made things convenient for.

In order to achieve the purpose, the technical scheme of the utility model is that the outer tube comprises an outer tube and an inner tube, the outer tube comprises an outer tube first end, two open slots are symmetrically arranged on the outer peripheral surface of the outer tube first end, a through hole penetrating through the tube wall of the outer tube is arranged at the bottom of the open slot, an arc-shaped block is arranged in the open slot, the arc-shaped block is fixed in the open slot through a screw detachable manner, a limiting bulge penetrating through the through hole is extended on the inner wall of the arc-shaped block, the end surface of the limiting bulge, far away from the arc-shaped block, is an arc surface, and; the inner pipe comprises an inner pipe first end, the inner pipe first end is inserted into the outer pipe first end, a radially outward protruding retaining ring is arranged at the inner pipe first end, and the retaining ring is used for blocking the limiting protrusion.

Preferably, the arc-shaped block is provided with two countersunk through holes which are symmetrically arranged by a limiting bulge; the tank bottom of open slot is equipped with two screw holes with countersunk head through-hole one-to-one, and each screw hole and the coaxial center of corresponding countersunk head through-hole, and wear to be equipped with in each screw hole and the corresponding countersunk head through-hole the screw.

Preferably, an annular groove is formed in the peripheral surface of the baffle ring, and a sealing ring is installed in the annular groove.

Preferably, the outer tube further comprises an outer tube second end, and the outer tube second end is connected with an outer tube joint.

Preferably, the inner tube further comprises an inner tube second end, and the inner tube second end is connected with an inner tube joint.

The utility model has the advantages and the beneficial effects that: through setting up the arc piece at outer tube first end to the arc piece extends to have spacing arch, blocks spacing arch by the fender ring that sets up at the inner tube first end, thereby prevents to break away from between outer tube and the inner tube. When the outer pipe or the inner pipe is damaged and needs to be maintained and the sealing ring needs to be replaced, the disassembly operation between the outer pipe and the inner pipe is carried out; when the outer pipe is disassembled, the screw is only required to be unscrewed, the arc-shaped block is taken out from the open slot, and finally the first end of the inner pipe is pulled out from the first end of the outer pipe.

Fig. 1 is a schematic diagram of the present invention.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model discloses the technical scheme who specifically implements is:

as shown in fig. 1, a telescopic tube for a dust collector convenient to detach comprises an outer tube 1 and an inner tube 2, wherein the outer tube 1 comprises a first end of the outer tube, two open slots are symmetrically arranged on the outer peripheral surface of the first end of the outer tube, a through hole penetrating through the tube wall of the outer tube 1 is arranged at the bottom of each open slot, an arc-shaped block 3 is arranged in each open slot, the arc-shaped block 3 is detachably fixed in each open slot through a screw, a limiting protrusion 4 penetrating through each through hole extends from the inner wall of each arc-shaped block 3, the end surface, far away from the arc-shaped block 3, of each limiting protrusion 4 is an arc surface, and the; the inner pipe 2 comprises an inner pipe first end, the inner pipe first end is inserted into the outer pipe first end, a radially outward protruding baffle ring 5 is arranged at the inner pipe first end, and the baffle ring 5 is used for blocking the limiting protrusion 4.

The arc-shaped block 3 is provided with two countersunk through holes 6, and the two countersunk through holes 6 are symmetrically arranged by the limiting bulges 4; two threaded holes 7 which are in one-to-one correspondence with the countersunk head through holes 6 are formed in the bottoms of the open grooves, each threaded hole 7 and the corresponding countersunk head through hole 6 share the same axis, and the screws penetrate through the threaded holes 7 and the corresponding countersunk head through holes 6.

An annular groove is arranged on the peripheral surface of the baffle ring 5, and a sealing ring 8 is arranged in the annular groove.

The outer tube 1 further comprises an outer tube second end, which is connected to an outer tube fitting.

The inner tube 2 further comprises an inner tube second end connected to an inner tube connector.

The utility model has the advantages and the beneficial effects that: through setting up arc piece 3 at outer tube first end to arc piece 3 extends there is spacing arch 4, blocks spacing arch 4 by setting up the fender ring 5 at the inner tube first end, thereby prevents to break away from between outer tube 1 and the inner tube 2. When the outer pipe 1 or the inner pipe 2 is damaged and needs to be repaired and the sealing ring 8 needs to be replaced, the disassembly operation between the outer pipe 1 and the inner pipe 2 is carried out; when the disassembly is carried out, the screw is only required to be unscrewed, the arc-shaped block 3 is taken out from the open slot, and finally, the first end of the inner tube is pulled out from the first end of the outer tube.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
