Abstract
The utility model discloses a spring fastening device of the telescopic tube, wherein the telescopic tube comprises an inner sleeve and an outer sleeve that are sheathed together. A spring buckle with a protruding particle is arranged inside one end of the inner sleeve, while a positioning hole is respectively arranged on the inner and outer sleeves at the position of the protruding particle; a resisting part that can resist against the bottom end of the spring buckle to prevent the spring buckle from gliding is arranged at the end part of the inner sleeve. The resisting part can be a choke plug that is inserted into the port of inner sleeve or formed that the end part of inner sleeve is directly flattened. When the protruding particle of the spring buckle or the button arranged on the protruding particle is pressed down, the protruding particle or button is shrunk to the inner wall of the inner sleeve but not into the inner sleeve upon the resistance of the resisting part so as to increase the using effect.
Description
Technical field
The utility model relates to the flexible rod member of leisure goods such as a kind of tent, folding seat, refers to a kind of spring fitting device of telescopic tube especially.
Background technology
Usually, tent or foldable chair, chaise longue etc. are for the benefit of collected, are carried or carry, and its bracing frame all is arranged to folding structure.And be to save the space, have the part rod member to be designed to the structure of telescopic tube, when needed two telescopic tubes are drawn back, when not required then with the inner sleeve sleeve in outer tube, launch and the purpose of folding thereby can reach.And, want between that fastening devices is set usually in order to make the unlikely retraction of two telescopic tubes that draw back.
The most common and simple fastening devices as shown in Figure 1, be provided with a snak link 3 with protruding grain in the end of the inner sleeve 1 of this inside and outside sleeve pipe 1,2, for ease of pushing, a button 4 can be fixed by this protruding grain place, and respectively is provided with a locating hole 11,21 on the inside and outside sleeve pipe 1,2 of button 4 positions.When inside and outside sleeve pipe 1,2 drew back, button 4 stretched out under the resilient force of snak link 3 outside two locating holes 11,21 like this, thereby inside and outside sleeve pipe 1,2 is fixed, and then can prevent two retractions.And when desiring folding, pressing button 4 shrinks in the outer tube 2 it, and inner sleeve 1 can slide in outer tube 2 like this, thereby inner sleeve 1 can be inserted in the outer tube 2, to reach the purpose of folding.
Yet, because the tube wall of sleeve pipe is thinner usually, when pressing button 4, it not only can bounce back in the outer tube 2, even also can contract to inner sleeve 1, in case and in the button 4 retraction inner sleeves 1, want to take out then very difficult, and button 4 related snak links 3 contract to inner sleeve 1, also can deviate from from the end of inner sleeve 1, have brought great inconvenience to use like this.
The utility model content
The purpose of this utility model is to provide a kind of spring fitting device of telescopic tube, and it can prevent that snak link is in pushing process retraction inner sleeve.
For achieving the above object, technical solution of the present utility model is: a kind of spring fitting device of telescopic tube, this telescopic tube comprises inner sleeve and the outer tube that is nested together, in the end of inner sleeve, be provided with a snak link with protruding grain, on the inside and outside sleeve pipe of protruding grain position, respectively be provided with a locating hole, be provided with one in the end of inner sleeve and can replace the snak link bottom and the top that prevents its downslide.
The protruding grain place of described snak link is fixed with a button.
Described top is the plug that inserts in the inner sleeve port.
Described top forms for directly the inner sleeve end being flattened.
After adopting such scheme; owing to being provided with one in the inner sleeve end of telescopic tube, the utility model can replace the top that the snak link bottom prevents its downslide; like this; at the protruding grain of pushing snak link or when being located at button on the protruding grain; even protruding grain or button contract to inner sleeve inwall place; also because of the replacing of top, and in can the retraction inner sleeve, thereby result of use increased.
Description of drawings
Fig. 1 is the structural representation of existing telescopic tube spring fitting device;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation that the utility model is applied to tent bracket;
Fig. 4 is the structural representation of another embodiment of the utility model.
The specific embodiment
As shown in Figure 2, telescopic tube described in the utility model comprises inner sleeve 1 and the outer tube 2 that is nested together.Be provided with a snak link 3 with protruding grain in the end of inner sleeve 1, the protruding grain place of this snak link 3 is fixed with a button 4, and respectively is provided with a locating hole 11,21 on the inside and outside sleeve pipe 1,2 of button 4 positions.
Crucial part of the present utility model is: be provided with one at the port of inner sleeve 1 and can replace snak link 3 bottoms and prevent the plug 5 of its downslide.When mounted, after snak link 3 is packed into from the port of inner sleeve 1, fill in plug 5 again, to withstand snak link 3.Like this, when pressing button 4, even button 4 contracts to inner sleeve 1 inwall place, also because of the replacing of plug 5, and in can retraction inner sleeve 1, thereby increased result of use.
Telescopic tube described in the utility model can be applicable to the position that various tents, foldable chair etc. have scalable rod member, as shown in Figure 3, is the utility model and is applied to structural representation on the tent.
As shown in Figure 4, it is another embodiment of the present utility model.Among this embodiment, above-mentioned plug 5 replaces with a top 6.This top 6 is directly inner sleeve 1 end to be flattened and formed.Can illustrate by present embodiment; described plug 5 and top 6; mainly be for replacing snak link 3; to prevent its downslide; thereby can prevent that button 4 from contracting to inner sleeve 1; therefore the structure and the shape of plug 5 and top 6 can not be confined to form shown in the figure, as long as it can achieve the above object, and promptly should be in protection domain of the present utility model.
