Abstract

The utility model discloses self-adaptive pipe feet. The lower ends of the pipe feet are provided with a telescopic pipe which is connected with screw bolts, and the upper side of the telescopic pipe and the lower sides of the installing holes of the screw bolts are provided with sliding grooves which perforate the installing holes of the screw bolts. The internal part of the telescopic pipe and the lower sides of the screw bolts are provided with springs; the upper ends of the springs can hold the screw bolts; the lower ends can push on the barrier position in the telescopic pipe, and the internal parts on the upper ends of the pipe feet are fixed with screw plugs with screw holes which are easy to install and dismount. Thus, the utility model can be automatically suitable for ground height, and a plurality of pipe feet can totally touch down. The utility model has the advantages of stable and firm support of appliances and uniform stress. The utility model is widely suitable for being used for supporting feet of various appliances.

Description

The self-adapting type pin

The utility model relates to a kind of pin, particularly a kind of self-adapting type pin.

Some apparatus need a plurality of pins to support, for example trampoline, desk etc., pin all is a regular length, when the out-of-flatness of ground, a plurality of pins of same apparatus just can all not land, apparatus supports steadily, firmly like this, not only be inconvenient to use, and when on apparatus, applying very big pressure, because of apparatus supports inhomogeneous stressed irregular, can damage apparatus, even single pin is stressed big, can destroy supporting surface; When supporting surface destroys when irregular, apparatus supports stressed more inhomogeneous, can aggravate to damage apparatus again, forms the circulation of feeling sick; Moreover now pin all is to be fixed on the apparatus, and general pins is all longer, deposits and transportation takes up room greatly, and it is big to take usable area, the cost of transportation height.

Main purpose of the present utility model is to provide a kind of self-adapting type pin that can adapt to ground level automatically;

Another purpose of the present utility model is to provide a kind of easy pin of installing and discharge.

The utility model is to realize above-mentioned purpose like this:

The self-adapting type pin, the useful bolted telescoping tube in the lower end of pin pipe, the slide slot that connects with the installing hole of bolt is arranged on the telescoping tube, below the bolt mounting holes, in the telescoping tube, under the bolt spring is housed, bolt is withstood in the upper end of spring, the lower end of spring withstands on stopping on the position in the telescoping tube, and the internal fixation of pin pipe upper end has the plug screw of band screw.

Because the useful bolted telescoping tube in lower end of pin pipe, the slide slot that connects with the installing hole of bolt is arranged on the telescoping tube, below the bolt mounting holes, in the telescoping tube, under the bolt spring is housed, bolt is withstood in the upper end of spring, and the lower end of spring withstands on stopping on the position in the telescoping tube, like this when the out-of-flatness of ground, the utility model can adapt to ground level automatically, a plurality of pins are all landed, and apparatus supports steady, firm, stressed even like this.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description.

Fig. 1 is the front view of a kind of Application Example of the present utility model;

Fig. 2 is a structural representation of the present utility model.

With reference to Fig. 1, on the pipe 2 of apparatus, a plurality of the utility model self-adapting type pins that useful screw 1 is fixed, Fig. 2 is a structural representation of the present utility model, that is the A-A cutaway view of Fig. 1, with reference to Fig. 1, Fig. 2, the telescoping tube 10 that the useful bolt 7 in the lower end of pin pipe 3 connects, the slide slot 6 that connects with the installing hole of bolt 7 is arranged on the telescoping tube 10, below bolt 7 installing holes, in the telescoping tube 10, bolt is equipped with spring 97 times, bolt 7 is withstood in the upper end of spring 9, and the lower end of spring 9 withstands on telescoping tube 10 interior stopping, and on the position 5, the internal fixation of pin pipe 3 upper ends has the plug screw 4 of band screw; Stop that position 5 is that the lower port of telescoping tube 10 is dwindled the external diameter that closes up less than spring 9, or the lower port of telescoping tube 10 is welded with back-up ring, perhaps block the lower end of spring 9, perhaps directly block the lower end of spring 9 with the end of the fixing glue pin 8 in telescoping tube 10 lower ends with pin; The utility model can adapt to ground level automatically like this, and a plurality of pins are all landed, and it is steady, firm that apparatus supports, stressed even; Moreover the internal fixation of pin pipe 3 upper ends has the plug screw 4 of band screw, is easy to install and discharge the utility model by screw 1 like this.

Claims

1. self-adapting type pin, comprise pin pipe (3), the telescoping tube (10) that it is characterized in that the useful bolt in lower end (7) connection of pin pipe (3), telescoping tube (10) is gone up, bolt (7) has below the installing hole and the slide slot (6) of the installing hole of bolt (7) perforation, in the telescoping tube (10), under the bolt (7) spring (9) is housed, bolt (7) is withstood in the upper end of spring (9), the lower end of spring (9) withstands on stopping on the position (5) in the telescoping tube (10), and the internal fixation of pin pipe (3) upper end has the plug screw (4) of band screw.

2. self-adapting type pin according to claim 1 is characterized in that stopping that position (5) is that the lower port of telescoping tube (10) is dwindled the external diameter that closes up less than spring (9).
