Dust catcher transfer tube is related to a kind of for by the sweep-up pipe of dust catcher, dust suction work head etc. as shown in Fig. 1 ~ Fig. 3
Various attachmentes carry out quick, stable, flexible with slotting fitting structure.
The dust catcher transfer tube structure is mainly by structures such as the fastener tube 1 of circular tube shaped, adapter sleeve 2 and fastening gum covers 3
At the present embodiment is using on the left of view shown in FIG. 1 as the front end of transfer tube, rear end of the view right side as transfer tube；Wherein,
2 movable set of adapter sleeve is in 1 front end of fastener tube, and tightened relative pipe makees progressive axial reciprocating movement, and this structure is usually adopted
Connection structure is screwed with screw thread, i.e., 2 screw thread rotation movable set of adapter sleeve is in 1 front end of fastener tube, when 2 tightened relative pipe of adapter sleeve
When 1 rotation, the progressive axial that can be converted rotational motion in fastener tube 1 is moved back and forth, in the excircle of adapter sleeve 2
It is additionally provided with a plurality of anti-skid chequer on face, is had skidded when being rotated to avoid operation adapter sleeve 2.
The front end in adapter sleeve 2 and being located at fastener tube 1 is arranged in the fastening gum cover 3, which uses rubber
The flexible materials such as glue, silica gel are made, and quantity generally selects 1 ~ 3, and is successively set in adapter sleeve 2 along axial direction, actual use
In it is main choose 2 as shown in Figure 1 and be advisable, and as the main secure component in transfer tube for cooperating adapter sleeve 2 to lock.
It is equipped with annular groove 31 as shown in Figure 3 on the outer circumference surface of each fastening gum cover 3, and fastening glue is made by the annular groove
Internal projecting ring 32 is formed on the inner peripheral surface of set 3, arranged side by side 1 ~ 3 can also be used in the annular groove 31 fastened on 3 outer circumference surface of gum cover
A, then each annular groove 31 can make to form corresponding internal projecting ring 32 on the inner peripheral surface for fastening gum cover 3, so that the fastening gum cover 3
The structure similar to bellows is formd, but in actual use, or is advisable with choosing 1 annular groove 31 shown in Fig. 1, and use
After 1 annular groove 31, the shape for fastening gum cover 3 is just closely similar with the pulley in mechanical device.
The both ends of each fastening gum cover 3 further respectively have the small taper hole in the big inner end in outer end as shown in Figure 1, Figure 3, the taper hole
Outer end extends on the outer end face of fastening gum cover 3, and the inner end of taper hole extends on the internal projecting ring of fastening gum cover 3.
Meanwhile when fastening gum cover 3 selects as shown in Figure 12 to be mounted in adapter sleeve 2, then in two neighboring fastening glue
The end face spacer ring 4 for also needing setting hard material to make between set 3, the purpose is to: hold two fastening gum covers 3 can independently
Load fastening work, and stability when fastening can be promoted.
In addition, 2 outer end face of adapter sleeve is equipped with ring shoulder 21, then 3 front end face of fastening gum cover of front end can contact and limit
On the ring shoulder 21, to prevent the fastening gum cover 3 of front end from falling off from 2 front end of adapter sleeve；3 rear end face of fastening gum cover of rearmost end
It being equipped between 1 front end face of fastener tube and keeps circle 5, the front end face of the holding circle is in direct contact on the rear end face of fastening gum cover 3,
Keep the rear end face positioning assembling of circle 5 in the front end face of fastener tube 1, by keeping circle 5 that must guarantee to fasten gum cover 3 come preferable
It works normally.
The utility model can be equipped with detachable in transfer tube front end, i.e. adapter sleeve 2 and match slotting and be locked by fastening gum cover 3
Sweep-up pipe or dust suction work head, usage mode it is as follows: guarantee 2 tightened relative pipe 1 of adapter sleeve be in outermost end, i.e. left end
When, sweep-up pipe or dust suction work head can be inserted in adapter sleeve 2, then 2 tightened relative pipes 1 of rotational fastener set are made gradual
It being moved axially inward, that is, moves right, then two fastening gum covers 3 will be compressed axially simultaneously and generate flexible deformation, into
And it drives two internal projecting rings 32 to be formed simultaneously and embraces fastening in, that is, the sweep-up pipe in adapter sleeve 2 or dust suction will be plugged on
Work head is stablized locking；When reversely rotating adapter sleeve 2, until adapter sleeve tightened relative pipe 1 is in outermost end, i.e. left end
When, two fastening gum covers 3 elastic will restore, and sweep-up pipe or dust suction work head at this time can be unloaded out of adapter sleeve 2.
And transfer tube rear end, i.e. 1 rear end of fastener tube can also be equipped with the sweep-up pipe or dust suction work head of detachable close-fitting grafting
Or middle pipe 6, this is can be such as when pipe 6 in 1 rear end close-fitting grafting of fastener tube using the close-fitting connected structure that different tube diameters carry out
Again by 6 detachable close-fitting grafting another dust catcher transfer tube of middle pipe shown in Fig. 4, Fig. 5, to realize double end transfer tube
Using function, and the flexibility of transfer tube grafting combination is promoted, and bring convenience to using.
The above is only specific embodiment of the utility model, it should be appreciated by those skilled in the art that any and reality
The equivalent structure design of example is applied, should be included within the scope of protection of this utility model.
