Abstract

The utility model relates to a pipe bundle structure which is mainly composed of an inner pipe, an outer pipe and a fixing clamp, wherein the fixing clamping is buckled and connected with the inner pipe and the outer pipe, and one end of the inner pipe is sheathed in the outer pipe. The utility model is characterized in that a ring groove is arranged in the preset position on the inner pipe, the inner pipe is provided with a mark at the point near the ring groove, and a clamping convex point is arranged on the inner side of a buckling sheet of the fixing clamp. The utility model can make use of the mark to provide the para position of the fixing clamp, so that the clamping convex point is exactly buckled into the ring groove. The utility model can make a consumer to directly carry out the actions of buckling assembly when the consumer uses the utility model, so that the defect of the traditional pipe bundle structure can be overcome, and the inner pipe has a blocking effect. Therefore, the efficacy that the inner pipe can not easily slide off or disengage from the outer pipe is produced, and the breakthrough on the design of the utility model of a manufacturer is improved. The utility model can be widely used for connecting various inner pipes and outer pipes.

Description

A kind of Pipe bundle structure

Technical field

The utility model relates to a kind of Pipe bundle structure, particularly the improvement of the Pipe bundle structure that connects about a kind of inner and outer pipe.

Background technique

Press, practise the formula Pipe bundle structure, as shown in Figure 1, the inner and

outer pipe

1,2 of two different calibers, the mounting fixture 3 of arranging in pairs or groups snaps together inner and

outer pipes

1,2 assemblings.But since cramp 33 inboards of mounting fixture 3 only be simple arc convex body 331 ', and interior pipe 2 is for merely adopting the whole smooth surface design, therefore when fastening assembling, the bottom circular aperture 312 of mounting fixture 3 is set in an end of outer tube 1, one end of interior pipe 2 is set in the mounting fixture 3 top circular holes 312, the user according to the height that needs pipe in the Height Adjustment till after, utilize finger to pin spanner 332 places of cramp 33, make that cramp inner edge 333 is approaching and when being fitted in anchor clamps outer rim 314, arc convex body 331 ' can block the interior pipe 2 of whole smooth surface forms the interior pipe 2 of unmarked or mark.This shows that habit formula Pipe bundle structure is unfavorable for directly fastening the action of assembling, and manages 2 no backstop effects and easy landing or disengaging outer tube 1 in making.The existence of above-mentioned shortcoming is the normal use puzzlement that takes place of habit formula Pipe bundle structure, so can be proved conclusively by aforementioned, manufacturer is making the breakthrough of also wishing to seek predicament in the design.

Summary of the invention

The purpose of this utility model provides a kind of Pipe bundle structure, and it mainly is made up of interior pipe, outer tube and mounting fixture, with described mounting fixture be fastened and connected described in pipe and outer tube, described in an end of pipe be set in described outer tube inside; It is characterized in that: pipe is gone up the pre-position and is provided with annular groove in described, and described interior pipe is gone up near described annular groove place and is provided with mark; The cramp inboard of described mounting fixture is provided with the blocking salient point that is snapped in described annular groove.

The width and the corresponding setting of number of the width of described blocking salient point and number and described annular groove.

The weight that the quantity of described cramp is born according to pipe in described and being provided with.

The utility model is owing to take above design, therefore can directly fasten the action of assembling when helping the Consumer and using, be overcome the shortcoming of habit formula Pipe bundle structure, pipe has the backstop effect in making, be difficult for landing or break away from outer tube, and improve the breakthrough of manufacturer in designing for manufacturing.

Embodiment

At first, as Fig. 2, shown in Figure 3, practise the formula Pipe bundle structure and can cause the action that is unfavorable for directly assembling fastening, no any number of altitude on the smooth interior pipe 2, and because no backstop effect, pipe 2 is done easy landing of time spent or is broken away from circular hole 11 inside of outer tube because of external force in causing.Habit formula Pipe bundle structure makes that cramp inner edge 333 is approaching and when being fitted on the anchor clamps outer rim 314, arc convex body 331 ' can block the interior pipe 2 on whole smooth surface, can form the interior pipe 2 of unmarked or mark simultaneously, but because no backstop effect causes interior pipe 2 to do easy landing of time spent or break away from circular hole 11 inside of outer tube 1 because of external force.

Relatively, as shown in Figure 4, the utility model mainly is that the pre-position is provided with several annular groove 21 on the pipe face of interior pipe 2, and be provided with mark 22 near annular groove 21 places on the interior pipe 2, be beneficial to mounting fixture 3 contrapositions, because of mounting fixture 3 is provided with cramp 33, the blocking salient point 331 of cramp 33 inboards is able to directly accurate location card on annular groove 21, finish tube bank of the present utility model and improve structure, be beneficial to the action that directly fastens assembling, pipe 2 produces the backstop effect is arranged in making.

On the other hand, as Fig. 5, shown in Figure 6, the pedestal 31 of mounting fixture 3 of the present utility model is provided with a fixing port 313, is held cramp 33.After cramp 33 is inserted, hold-down bars 32 bolts are gone into jack 311 and fixed jack 334, because during with the past interior button of finger spanner 332, blocking salient point 331 has been finished in location card several annular groove 21 on interior pipe 2 pipe faces, even if pipe 2 in forcing in, interior pipe 2 can landings yet or are broken away from outer tube 1.Again, the blocking salient point 331 of the pipe face annular groove of interior pipe 2 21 and cramp 33 inboards, both take the design that cooperatively interacts, its width, number can be according to need, promptly in the pipe 2 weight sizes of desiring to bear, freely set.The quantity of cramp 33 also can be according to need in addition, and the big freedom in minor affairs of promptly interior pipe 2 weight of desiring to bear is set.

In sum, the utility model is a kind of structure-improved of tube bank, but nationality reaches aforesaid purpose and effect by the collocation design of annular groove and blocking salient point, can directly fasten the action of assembling when being beneficial to the Consumer and using, make interior pipe have the backstop effect to be difficult for landing or break away to produce, and improve the breakthrough of manufacturer in designing for manufacturing in the effect of outer tube.The utility model is improved the shortcoming that the formula of habit structure exists, and makes product have more practical effect in limitation technical development field.
