Abstract

A case capable of climbing stairs is characterized in that a handle 1, a pull rod 2, a case body 4 and tripods 5 are included; the case body 4 is cuboid; the pull rod 2 is made of stainless steel and has one end connected with the handle 1 and the other end inserted from the upper surface of the case body 4 to the lower surface of the case body 4; the rod body of the pull rod 2 is arranged under the surface of the bottom; round holes are formed in the tripods 5, and the inside diameter of each round hole is slightly larger than the outside diameter of each bearing 8; three supporting rods have the same length which is equal to the height of a common stair 3; the bearings 8 are cylinder-shaped, and threads are formed at two ends of the bearings 8; the bearings 8 pass through the inner round holes of the tripods 5; screw caps 7 are connected with the bearings 8 through threads; the two tripods 5 are arranged on the bearings 8 on the two sides at the bottom of the case body 4 respectively; and rollers 6 are mounted at the end parts of the three supporting rods respectively. The case can not only be pulled to move on a level road, but also be pulled over the stair 3, and has the advantages of convenience in operation, simple structure and easiness in manufacturing.

Description

Climbing stairs ladder chest

Technical field

The utility model relates to a kind of pull bar chest, especially a kind of climbing stairs ladder chest.

Background technology

Traditional pull bar chest can only drag on more smooth road mostly, and when going upstairs, and can only be screwed in the hand or shoulders piggyback, and is not only hard, and time-consuming, more painstaking when especially chest is heavy especially, even removes motionless.

The utility model content

In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of climbing stairs ladder chest, and this chest can not only drag on level road, goes upstairs but also can drag.

In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of climbing stairs ladder chest, it is characterized in that: it is made of handle 1, pull bar 2, casing 4, three supports 5; Casing 4 is a cuboid, and pull bar 2 is that stainless steel constitutes, and an end connects handle 1, and the other end is inserted into the lower surface of casing 4 from the upper surface of casing 4, and pull bar 2 shafts are located in the epidermis of bottom; Establish circular hole in three supports 5, the circular hole internal diameter is bigger slightly than bearing 8 external diameters, and three pole length equate, and are highly suitable with general stair 3; Bearing 8 is a cylinder, and two ends are provided with screw thread, and bearing 8 passes circular holes in three supports 5, and nut 7 and bearing 8 are by being threaded; Two three supports 5 are separately positioned on the bearing 8 of casing 4 two bottom sides, and roller 6 is all installed in three pole ends.

The beneficial effects of the utility model are: it can not only drag on level road, and can drag and go upstairs 3, and is easy to operate, simple in structure, is easy to make.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Wherein 1-handle, 2 pull bars, 3-stair, 4-casing, 5-three supports, 6-roller, 7-nut, 8-bearing.

The specific embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of climbing stairs ladder chest, it is characterized in that: it is made of handle 1, pull bar 2, casing 4, three supports 5; Casing 4 is a cuboid, and pull bar 2 is that stainless steel constitutes, and an end connects handle 1, and the other end is inserted into the lower surface of casing 4 from the upper surface of casing 4, and pull bar 2 shafts are located in the epidermis of bottom; Establish circular hole in three supports 5, the circular hole internal diameter is bigger slightly than bearing 8 external diameters, and three pole length equate, and are highly suitable with general stair 3; Bearing 8 is a cylinder, and two ends are provided with screw thread, and bearing 8 passes circular holes in three supports 5, and nut 7 and bearing 8 two ends are by being threaded.

In Fig. 2, second embodiment shown in Figure 3, two three supports 5 are separately positioned on the bearing 8 of casing 4 two bottom sides, and roller 6 is all installed in three pole ends.

When using the utility model stair climbing 3, a pole is stuck on the longitudinal surface of stair 3, a coupled support just in time is stuck on the horizontal plane of stair 3, continue the pulling chest, three poles are rotated around bearing 8, another root pole is stuck in again on the longitudinal surface of stair 3, and so circulation has just realized that chest climbs the characteristic in building.
