It is arranged in lower limit set 42, and is connected to the first end of support beam 22.
Shown in Figure 10, in order to sliding beam 31 is implemented positioning function, fixation kit 40 also includes knob 43, knob 43
Including knob cap 431 and the threaded rod 432 that is connected with knob cap 431, the second end of union joint 11 is provided with groove C118, recessed
Being provided with the second nut 46 in groove C118, first cell wall of groove C118 is provided with through hole B119, threaded rod 432 is by logical
Hole B119 and the second nut 46 coordinate.And on second cell wall of groove C118, it being provided with opening B1110, opening B1110 is by recessed
Groove C118 connects with connecting hole 111, and now, the stator 412 of the lower limit set 42 being arranged in connecting hole 111 is overlapped on
On opening B1110, and the shape of opening B1110 adapts, it is ensured that the stator 412 on lower limit set 42 and opening B1110
Alignment, the stator 412 preventing lower limit set 42 is backing out from union joint 11.According to above-mentioned structure, work as threaded rod
432 through the second nut 46 time, be just connected to upper limit set 41 on stator 412 on.Use the telescopic machine of the present embodiment
During structure, if needing to make telescoping mechanism be in extended configuration, as shown in figure 13, it is only necessary to knob 43 is loosened, then make sliding
Dynamic beam 31 docks with support beam 22, then knob 43 is tightened, now threaded rod 432 away from knob cap 431 one end under
The stator 412 of stop collar 42 applies the effect of power, makes the open C 415 of lower limit set 42 diminish, is fixed by sliding beam 31
On union joint 11, otherwise, when needs make telescoping mechanism be in contraction state when, as shown in figure 14, only need to will loosen,
Again sliding beam 31 is slided as support beam 22 integrator along the chute 21 of support beam 22, knob 43 is tightened, behaviour
Make simple, it is not necessary to by other extracting tools, it is simple to user uses.
Further in conjunction with shown in Fig. 1 to Figure 14, the assemble flow of the telescoping mechanism of the present embodiment is as follows:
The assembling of upper limit set 41: first, puts the stator 412 of upper limit set 41 into the spacing hole 414 of upper limit set 41
In, then the first nut 452 is put into the groove B116 of union joint 11, the first nut 452 is alignd with through hole A1112,
Then will assemble upper limit set 41 and stator 412 will load connecting hole 111 first end, make the second end overlap joint of upper limit set 41

Mobile.The projection 411 of upper limit set 41 is fastened in groove A115, prevents upper limit set 41 play in connecting hole 111.
The structure rib 416 of upper limit set 41 coordinates with the first nut 452, prevents the first nut 452 from dropping out in groove B116.
The assembling of lower limit set 42: with upper limit set 41 turn that to join process consistent.First, the stator 412 of lower limit set 42
Put in the spacing hole 414 of lower limit set 42, the second nut 46 is put into groove C118, by the second nut 46 and through hole
B119 aligns, and then the lower limit assembled set 42 and stator 412 is loaded in the second end of connecting hole 111, makes lower limit
Second end of set 42 is connected on first step 112, and the flange 413 of lower limit set 42 is overlapped on the 4th step 1111, anti-
Only lower limit set 42 moves up and down in connecting hole 111.The structure rib 416 of lower limit set 42 coordinates with the second nut 46,
Prevent the second nut 46 from dropping out in groove C118.
The assembling of carrier parts assembly: assembled by the installing hole 311 of the salient point 51 of two slide blocks 50 with sliding beam 31, will assembling
Good sliding beam 31 and slide block 50 assembly are inserted in the chute 21 of support beam 22, make the sliding beam 31 can be real in support beam 22
Existing expanding-contracting action.Again the carrier parts assembly assembled from top to bottom is penetrated in connecting hole 111, make upper bracket 20, i.e. support
Beam 22 is inserted in upper limit set 41, makes the second end of support beam 22 be connected on first step 112, it is ensured that support beam 22 cannot
Continue down to slide.Lower carriage 30, when i.e. sliding beam 31 extends, fit with first step 112 in the lower surface of slide block 50, sliding
Dynamic beam 31 cannot continue to glide, it is ensured that the stroke of sliding beam 31.
Finally, stud 451 is screwed with the first nut 452 by through hole A1112, then by knob 43 by through hole B119 and
Second nut 46 screws, and completes the assembling to whole telescoping mechanism.
According to another embodiment of the present invention, it is provided that a kind of box fan, this box fan includes telescoping mechanism, telescopic machine here
Structure is above-mentioned telescoping mechanism.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Utilize the telescoping mechanism of the present invention, if needing to make telescoping mechanism be in contraction state, only need to be by lower carriage along slide
It is integrated to upper bracket, is fixed by fixation kit, and if needing to make telescoping mechanism be in extended configuration, only need
It is stretched to lower carriage dock with upper bracket, and is fixed on union joint by fixation kit.Visible, telescoping mechanism whole
Individual telescopic process is slided realization by lower carriage in chute, it is not necessary to use extracting tool i.e. to can reach retraction volume, and to stretching
It is when contracting mechanism collects, simple to operate, it is easy to accomplish.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
