Description

Location device for expansion tabe for vertical fan

The utility model system refers to a kind of simple structure especially relevant for a kind of upright fan telescopic pipe positioning device, and it is convenient to assemble, and the location is firm really and upright fan telescopic pipe positioning device safe in utilization.

The positioning device of known upright fan telescopic pipe, pattern is various too numerous to enumerate, must be equipped with elastic element yet on the whole go up all, for example spring or clockwork spring, just flexible and locating; Therefore, it is numerous and diverse to have a structure, and assembling trouble is time-consuming, and the location is firm really inadequately, and defective such as dangerous in the use.

The main purpose of the utility model is promptly providing a kind of simple structure, and it is convenient to assemble, and is safe in utilization and locate firm upright fan telescopic pipe positioning device, and it can improve the defective of known devices.

About the utility model for reaching above-mentioned purpose and effect, the concrete structure that is adopted, the existing act with next preferable possible embodiments, details are as follows for conjunction with figs..

Shown in Figure 1 is the utility model embodiment's three-dimensional exploded view

Shown in Figure 2 is that enlarged diagram is analysed and observe in the utility model embodiment's combination

As shown in drawings, the structure of the utility model includes seat pipe 1 and telescopic pipe 3; Wherein, the bottom of this pipe 1 is fixed on the base 2, and telescopic pipe 3 is inserted within this pipe 1, and its bottom is bolted with a disk body 31, with limit on stretching as telescopic pipe 3; And seat pipe inside, 1 top is more one-body molded a deck 10 arranged, deck 10 has center hole 11, be inserted in for telescopic pipe 3, then has reinforcement plate 12 around the center hole 11, can separate into some spaces 13, wherein a space 13 just can be inserted one and support sheet 14, manages 1 side for a bolt 15 from seat and stretches into and pass screw to sheet 14, to prop up deck 10, so that telescopic pipe 3 is propped up the location; These structures are roughly identical with known technology, are not the feature place for the utility model, so repeat no more.

End on the center hole that is characterised in that this deck 10 11 of the utility model, have one and be the taper shrinkage pool 16 that slopes inwardly downwards, insert for an identical shaped cone 4, this cone 4 closely cooperates so can form with taper shrinkage pool 16 because available rubber material is made; One upper shield 5 is made for the rubber material, is placed on the mouth of pipe of seat pipe 1, its bottom has equidistantly being referred to as three fins 52, and these fins 52 penetrate in the seat pipe 1, and has a perforation 53, snap in for a clip convex body 17 that is positioned on seat pipe 1 inwall, and upper shield 5 clips can be located; And a fixed cover 6, also be that the rubber material is made, be placed in seat pipe 1 inwall, and be butted on the bottom surface of deck 10; And the heart all has slotted eye 51,41,61 among above-mentioned upper shield 5, cone 4 and the fixed cover 6, forms same aperture with deck center hole 11, and can be inserted in for telescopic pipe 3.

During according to above-mentioned structure Assembly, operate according to following order: (1) is taken a seat fixed cover 6 earlier and is managed 1 inwall by the below cover, and is butted on deck 10 bottom surfaces and fixes; (2) cone 4 is inserted in the taper shrinkage pool 16 of deck; (3) will be in sheet 14 be inserted one of deck space 13, and bolt 15 is managed 1 sidewall from seat screw in and pass screw to sheet 14; (4) upper shield is pressed on a mouth of pipe of pipe 1 for 5 times, makes its fin 52 slip over clip convex body 17, make clip convex body 17 snap in perforation 53, and upper shield 5 clips can be located; (5) telescopic pipe 3 is inserted in from top to bottom, again in the solid disk body 31 of its bottom spiral shell; (6) seat pipe 1 is fixed in above the base 2; To finish whole assembling works.

The utility model is using under the normality, bolt 15 inwardly push against deck 10 make telescopic pipe 3 location can't on stretch or under contract, as shown in Figure 2; Yet when unscrewing bolt 15, the strength that deck 10 is pushed against disappears immediately, and can hold on the telescopic pipe 3 and draw or press down this moment, and then screw bolt 15, telescopic pipe 3 can be located once again to prop up deck 10.

So by above explanation as can be known, the utility model has obviously had following all advantage and effect in structure, assembling and use, and more progressive practical more than known devices:

(1) constructs comparatively Dan Jian, only must be equipped with cone 4, upper shield 5 and fixed cover 6.

(2) assembling is more convenient, and cone 4, upper shield 5 and fixed cover 6 are owing to being to utilize the rubber material to make, so fashionable with seat pipe 1 cover, not only very simply rapidly, and its degree of adaptability is also quite closely good.

(3) because of there not being any elastic element, so when flexible the use, obviously safer.

(4) because of only bolt 15 must being screwed or loosen, promptly scalable or location is so have location firm effect really.

In sum, the concrete structure that the utility model embodiment is disclosed, obviously completely different with known technology, have simple structure, it is convenient assemble, safe in utilization and locate advantages such as certain firm.

Claims (1)

1, upright fan telescopic pipe positioning device comprises:

A pipe is fixed on the base, and its inside, top has a deck integratedly, and this deck has center hole and some spaces; Wherein, in one of this space, can insert one and support sheet, be screwed into and pass from seat pipe sidewall to sheet for a bolt; And

One telescopic pipe is inserted in this pipe, and its bottom is bolted with a disk body, to limit as on flexible;

It is characterized in that this deck center hole upper end has a taper shrinkage pool, for inserting an identical shaped cone, the mouth of pipe of seat pipe then is sheathed with a upper shield, the bottom of this upper shield also has fin, to stretch in the seat pipe and can be by clip convex body clip location, a seat inner tube wall is positioned at the deck bottom surface and also is with a fixed cover in addition; Make telescopic pipe can pass upper shield, cone, deck and fixed cover from top to bottom, relend and help screwing or loosening of bolt, and scalable location.
