Abstract
The utility model discloses a break-camp leg pipe height adjustment bracket with a self-protection structure. The bracket comprises a bracket body, a reset spring, a pin rod and a chock plug; an axial through hole is formed in the bracket body, the inner wall of the through hole is provided with an axial and concentric spacing block, and a concentric groove is formed between the concentric spacing block and the inner wall; the pin rod is radially arranged in the bracket body, and the reset spring for resetting the pin rod is arranged between the pin rod and the bracket body; one end of the pin rod is provided with the chock plug and is inserted into the axial through hole. When the bracket is used for adjusting the height of a leg pipe, the inner pipe and the outer surface of the leg pipe cannot be scratched, and the sliding is smoother.
Description
Technical field
The utility model relates to a kind of height adjustment mechanism, refers in particular to a kind of band from the break camp leg pipe height bracket of safeguard structure.
Background technology
In prior art, break camp leg pipe height regulative mode generally comprises following several: one, the mode that adopts upper and lower two joint leg pipes to peg graft regulates leg pipe height, being about to upper leg pipe is plugged on lower leg-tube, its defect is: because upper and lower two joint leg pipes independently arrange, carry and collect inconvenience, and installing and the upper and lower leg pipe of easy scratch during dismounting, even can hurt hand.Two, the mode that adopts the different leg pipe of bore to be socketed regulates leg pipe height, and the leg pipe that bore is little is flexible in the large leg pipe of bore, and locks by bearing pin, its defect is: during the different leg pipe of bearing pin locking bore, easily by the scratch of leg pipe and form burr, damage leg pipe.
In view of the described defect of prior art break camp leg pipe height regulative mode, the inventor furthers investigate, and develops a kind of break camp leg pipe height that overcomes described defect and regulates de-frame, and this case produces thus.
Utility model content
The purpose of this utility model be to provide a kind of install and easy to use and band that can scratch leg pipe from the break camp leg pipe height bracket of safeguard structure.
For reaching above-mentioned purpose, solution of the present utility model is;
A break camp leg pipe height bracket from safeguard structure, comprises bracket body, back-moving spring, pin rod and chock plug; In bracket body, form axially extending bore, through-hole wall arranges axially spacer with one heart, forms locked groove with one heart between spacer and inwall; Pin rod is radially arranged in bracket body, and the back-moving spring that pin rod is resetted is set between pin rod and bracket body; Chock plug is installed in pin rod one end, and installing stopper head end stretches in axially extending bore.
Further, chock plug is plastic cement chock plug.
Further, the pin rod other end arranges draw ring.
Further, draw ring skin is coated rosette by ultrasonic wave.
Further, between pin rod and bracket body, plug-in unit is set, plug-in unit is arranged on bracket body by holding screw.
Further, pin rod one end forms radially jack, and chock plug inserts in jack and pin rod interference fit.
Adopt after such scheme, the utility model is fixed on to leg pipe outer tube end with holding screw, leg pipe outer tube end inserts between concentric spacer and inwall and forms in locked groove, and leg pipe inner tube is being twitched in spacer inwall with one heart, be leg pipe outer tube with leg pipe inner tube between by concentric spacer, separated, can protect leg pipe inner tube outer surface not by scratch; When inner tube is slided within the outer tube, pin rod is resisted against inner tube outer surface by chock plug under the effect of back-moving spring, avoid metal pin rod directly to contact with inner tube outer surface, when inner tube is retracted to a certain position, in pin rod inserts under the effect of back-moving spring, in the locating hole of tube-surface, realizes and highly regulating and location.Therefore, while using the utility model to regulate leg pipe height, can scratch leg pipe inner tube outer surface, and it is comparatively smooth and easy to slide.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is used state diagram.
Label declaration
Bracket body 1 through hole 11
Chock plug 4 plug-in units 5
Draw ring 6 rosettes 7
Leg pipe outer tube 10 leg pipe inner tubes 20.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Consult shown in Fig. 1, a kind of band that the utility model discloses, from the break camp leg pipe height bracket of safeguard structure, comprises bracket body 1, pin rod 2, back-moving spring 3 and chock plug 4.
In bracket body 1, form axially extending bore 11, through hole 11 inwalls arrange axially spacer 12 with one heart, form locked groove 13 with one heart between spacer 12 and inwall.
For reducing the friction between pin rod 2 and bracket body 1, between pin rod 2 and bracket body 1, plug-in unit 5 is set, plug-in unit 5 is arranged on bracket body 1 by holding screw.
Chock plug 4 is installed in pin rod 2 one end, and chock plug 4 is preferably plastic cement chock plug, and to reduce the friction between chock plug 4 and leg pipe inner tube, chock plug 4 can be other material certainly, as rubber chock plug.Chock plug 4 ends are installed to be stretched in axially extending bore 11.
In the present embodiment, pin rod 2 one end form radially jack, and chock plug 4 inserts in jacks and pin rod 2 interference fit.
Pull for convenience pin rod 2, make its depart to leg pipe inner tube against, make leg pipe inner tube smooth and easy sliding in leg pipe outer tube, pin rod 2 other ends arrange draw ring 6.Can by ultrasonic wave, be coated rosette 7 at draw ring 6 skins.
As shown in Figure 2, when the utility model is used, with holding screw, be fixed on leg pipe outer tube 10 ends, leg pipe outer tube 10 ends insert between concentric spacer 12 and inwall and form in locked groove 13; The draw ring 6 that pulls outward, makes pin rod 2 drive chock plugs 4 to move, depart to leg pipe inner tube 20 against, now, leg pipe inner tube 20, twitching in spacer 12 inwalls with one heart, is adjusted to suitable height; Then, pin rod 2 is resisted against chock plug 4 in the locating hole of leg pipe inner tube 20 external surfaces under the effect of back-moving spring 3, thereby by leg pipe inner tube 20 and leg pipe outer tube 10 location, realizes leg pipe height and regulate.
Between the utility model leg pipe outer tube 10 and leg pipe inner tube 20, by concentric spacer 12, separated, protection leg pipe inner tube 20 external surfaces are not by scratch, and it is comparatively smooth and easy to slide.Simultaneously, also can sheath be set in leg pipe inner tube 20, sheath and concentric spacer 12 common supporting leg pipe inner tube 20 external surfaces, when leg pipe inner tube 20 is slided in leg pipe outer tube 10 in concentric, slide more smooth and easy, and can not cause sharp cutting edge scratch leg pipe outer tube 10 inwalls of leg pipe inner tube 20 upper port, thus, leg pipe outer tube 10 inwall burrs are scratch leg pipe inner tube 20 external surfaces conversely.
The foregoing is only preferred embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
