Diameter is identical with external first pipe upper end bore.
Said program has the beneficial effect that：Limited block is circle, has a diameter larger than internal braces upper end bore, more convenient to take
Go out, while the diameter of limited block is identical with external first pipe upper end bore, the limited block may be stuck in outside first and manage when in use
With the joining place of external second pipe, certain supporting role is played, is not easily broken, make the telescoping mechanism more firm, safety
Property higher.
Further, according to actual needs, the first pipe of outside or the hollow structure for lower end closed, bottom thickness
It is bigger than sidewall thickness.
Said program has the beneficial effect that：When in use, external first bottom of the tube is subjected to the dynamics of bigger, increases its bottom
Portion's thickness is more advantageous to bearing weight, and use is safer, and use scope is also wider.
Further, inner hub location setting in outer head cover top is fluted, groove diameter and internal stay tube upper end bore
It is in the same size.
Said program has the beneficial effect that：When in use, internal stay tube upper end be stuck in just it is recessed inside outer head cover top
In slot, make it more firm, will not loosen, use is safer.
In conclusion the utility model has the following advantages：
Mutually nested component can easily be shrunk to an entirety, occupied space in the reinforcement steady type telescoping mechanism
It is small, it is easy to carry, when in use, these components are strutted, by the supporting role of internal braces, making the outside for having stress demand
Component linking is stablized, and will not be loosened, will not be retracted, and using comfortable safety is stablized, is made at low cost, the easy to spread, later stage
With stable quality, service life is long the advantages that.

Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In one embodiment of the utility model, as shown in Figure 1, a kind of reinforcement steady type telescoping mechanism is provided, including：
Nested internal braces 1, internal stay tube 2, external first pipe 3, external second pipe 4, external third pipe 5 and outer head cover 6 successively；It is interior
Portion's strut 1 is the hollow structure of lower end closed, and lower end is male portion, and screw thread is provided with outside male portion；Internal stay tube 2 is both ends
The hollow structure of opening, lower end are internally provided with screw thread, screw thread and the 1 convex-shaped portion of internal braces of internal 2 lower end of stay tube
Screw thread matches, and internal 2 length of stay tube is more than the length of internal braces 1；External first pipe 3 is the hollow structure of both ends open；Outside
The second pipe of portion 4 is the hollow structure of both ends open；External third pipe 5 is the hollow structure of both ends open, is set outside the upper end
There is screw thread；Outer 6 two side of head cover is internally provided with and the external 5 matched screw thread of screw thread of third pipe；Internal braces 1, internal stay tube
2nd, external first pipe 3, external second pipe 4 and external 5 bore of third pipe are to be sequentially reduced from top to bottom, and upper end bore and phase
Mutually nested lower end bore size is identical or slightly larger than lower end bore nested therewith, is to cooperate in a word, not easily to fall off
Nested unit.
Internal braces 1, internal stay tube 2, external first pipe 3, external second pipe 4, external third pipe 5 and outer head cover 6, pipe
Diameter is sequentially increased, and each component can be nested in outside internal part completely, and mutually nested component passes through nozzle bore or spiral shell
Line is used cooperatively, and mutually nested without using component each under state, is screwed by outer head cover 6 and external 5 thread fitting of third pipe,
It is easy to carry with regard to that all components can be contracted in outer head cover 6 with inside external third pipe 5, occupying little space completely, it is specifically shown in
Fig. 2.
Internal braces 1 and internal stay tube 2 can be taken out when using, the two lower end is passed through screw threads for fastening forms one
Whole (forming internal braces), is then inserted into external first pipe 3 by 1 upper end of internal braces again, then to the inside of external first pipe 3
Passage makes the upper end of external first pipe 3 be stuck in the lower end of external second pipe 4, then makes the upper end of external second pipe 4 again forward
Passage is stuck in the lower end of external third pipe 5, and outer head cover 6 is sleeved on to the upper end of internal stay tube 2, is existed by outer 6 internal thread of head cover
It is screwed on external 5 upper external screw thread of third pipe, the global facility that internal braces 1 and internal stay tube 2 are formed then is pushed to advance, into
One step makes the complete clamping of remainder, and this combination makes to have the first pipe of outside 3 of stress demand, external second pipe 4 and outer
The linking of portion's third pipe 5 is stablized, and will not be loosened, will not be retracted, and using comfortable safety is stablized, is specifically shown in Fig. 3.
It is not very convenient when needing to take out internal braces 1, therefore the top of internal braces 1 is provided with limited block 7, limits
Position block 7 is integrally formed with internal braces 1, and the diameter of limited block 7 is more than 1 upper end bore of internal braces, but on the first pipe 3 of outside
Port diameter is identical, is easier to take out internal braces 1 when using in this way；Another effect of limited block 7 is the limit when in use
Position block 7 may be stuck in the joining place of the first pipe of outside 3 and external second pipe 4, plays certain supporting role, is not easily broken, makes
The telescoping mechanism is more firm, safety higher.
According to actual needs, external first pipe 3 can also be the hollow structure of lower end closed, the first pipe 3 of outside during because using
Bottom is subjected to the dynamics of bigger, therefore increases its bottom thickness, is more advantageous to bearing weight, use is safer, use scope
Also wider, outside 3 bottom thickness of the first pipe of the utility model design are bigger than sidewall thickness, can meet the need born more energetically
It asks.
It is fluted in outer 6 top inner hub location setting of head cover in order to further strengthen the stability of the telescoping mechanism,
Groove diameter and 2 upper end bore of internal stay tube are in the same size, when in use, internal 2 upper end of stay tube is stuck in outer 6 top of head cover just
In internal groove, make it more firm, will not loosen, use is safer.
The reinforcement steady type telescoping mechanism can also select each component material according to actual needs, such as alloy material (alloy
Steel, aluminium alloy, magnesium alloy, titanium alloy), carbon fiber, glass fibre etc., at low cost, combined method is simple, occupies little space,
It is easy to carry, it will not loosen, will not retract, it is comfortable safe using stablizing.
Although being described in detail with reference to attached drawing to specific embodiment of the present utility model, should not be construed as pair
The restriction of the protection domain of this patent.In the described range of claims, those skilled in the art are without creative labor
The dynamic various modifications that can be made and deformation still belong to the protection domain of this patent.
