Abstract

An adjustable support leg utilizing the spring extension effect is characterized in that a support plate is fixed at the upper end of the main body of the adjustable support leg, a support leg is arranged in a sliding chute; two screws and screw caps are arranged on the sliding chute; one screw is fixed in the middle of the support plate and the other screw is in sleeve joint with a shaft sleeve at the outer edge of the support plate; the two screws are connected through a spring; 2 to 5 bayonets are arranged at the outer edge of the lower end of the support plate; and the inside diameter of each bayonet is equal to the outside diameter of the shaft sleeve. Owing to the adoption of the adjustable support leg provided by the utility model, the expansion and contraction of support legs of a small-sized tool car can be achieved, and the support legs can be adjusted according to the required support angle.

Description

A kind of adjustable feet of utilizing the spring stretching action

[technical field]

The utility model relates to a kind of leg, is specifically related to be applied to a kind of adjustable feet of utilizing the spring stretching action that small instruments and tools car such as wagon for spraying salt is parked support.

[background technology]

Small instruments and tools car such as wagon for spraying salts etc. are when loading is parked, and leg and ground constitute to be supported, and can play and park effect temporarily, when it is advanced, leg need be packed up so that small instruments and tools garage advances.

And the leg of existing small instruments and tools car generally adopts steel pipe directly to be welded on the small instruments and tools car, when parking and ground constitute to support, this device is provided with simply, so but, advance in the process easily because the uneven small instruments and tools car that influences in ground obstacle or ground uses in small instruments and tools garage when in use because directly be welded on the car body and can't pack up.

[utility model content]

In order to overcome the deficiency of existing technology, the utility model provides a kind of adjustable feet of utilizing the spring stretching action, this device is connected on the small instruments and tools car both can play supporting role when parking, and also can select simultaneously to support height, can pack up in not use.This apparatus structure is provided with new reasonable, has very strong practicality.

Technical scheme that the utility model provides is: a kind of adjustable feet of spring stretching action of utilizing is characterized in that its body upper end is fixed with a support plate, during the chute groove is interior a leg is arranged; Have on the chute two screws and nut wherein an end be fixed on support plate middle part, an other screw socket axle sleeve is in the support plate outer rim, two screws connect by spring.

Described a kind of adjustable feet of spring stretching action of utilizing is characterized in that described support plate lower end outer rim has 2-5 bayonet socket, and its bayonet socket internal diameter equals the axle sleeve external diameter.

In the use leg is pulled down, leg drives axle sleeve along the rotation of support plate lower end outer rim, and sticks into bayonet socket under action of the spring, and can arrive the bayonet socket that is fit to according to the angular adjustment leg that small instruments and tools car needs support, and resetting obsolete the time gets final product.

The utility model beneficial effect: adopt this device can realize the folding and unfolding of small instruments and tools car leg, and can be according to required support angle adjustment.

Further understand feature of the present utility model and technology contents for making, see the utility model drawings and embodiments for details, yet appended graphic only for reference and explanation usefulness is limited the utility model.
