Abstract
The utility model discloses a universal wheel leg, and belongs to the technical field of an adjustable general caster wheel. The universal wheel leg comprises a leg tube, a universal wheel, and a leg tube seat. A sleeve is fixedly arranged at the lower portion of the leg tube and is movably connected with the leg tube seat through a thread. The leg tube seat is in a hemispherical structure. The radius of the inner wall of the leg tube seat is equal to or greater than the diameter of the universal wheel, and the length of the sleeve is greater than or equal to the height of the leg tube seat which is made of plastic-steel tubing. The universal wheel leg can be applied to table legs of a tea table, a table, a chair, industrial device and the like, and has the advantages of being stable in performance, easy to install, detachable, good in bearing capacity and the like.
Description
Technical field
The utility model provides a kind of castor leg, belongs to adjustable general castor technical field.
Background technology
Supporting leg or the leg pipe of the device such as common tables and chairs, tea table; it mainly is the Convenient table structure; for convenient mobile; conventional way is in the bottom of Convenient table castor leg to be installed; but the product stability after processing like this is relatively poor; some enterprises make improvements this; add cover in the universal wheel outside, supporting leg or leg pipe are supported, and universal wheel is protected; yet in the use procedure; still have unstable properties, install and extremely inconvenience of use, universal wheel is stressed irregular; easy aging breaking, service life is the defective such as short all.
Summary of the invention
The purpose of this utility model provides a kind of stable performance, easy for installation, detachable, castor leg that bearing capacity is good.
For realizing the utility model purpose, the technical scheme of taking is as follows:
A kind of castor leg comprises leg pipe, universal wheel and leg base, and described leg pipe bottom is installed with sleeve, and sleeve and leg base are flexibly connected by screw thread, and the leg base is hemispherical dome structure.
For obtaining better result of use, the utility model further arranges as follows:
The inwall radius of described leg base is equal to or greater than the diameter of universal wheel.
Described length sleeve is more than or equal to the height of leg base.
Described leg base adopts steel to mould tubing and makes.
Operation principle of the present utility model is as follows: when the leg pipe need to move, with the rotation of leg base, the leg base is moved up along sleeve pipe, until above ground level, can use universal wheel; When not needing universal wheel, again the leg base is rotated down along sleeve pipe, until contact with ground, the leg tube stay is risen, universal wheel is not contacted with ground.
Compare with existing castor leg technology, the beneficial effects of the utility model are as follows:
1, sleeve is fixedly mounted on the leg pipe, and leg base and sleeve adopt screw thread to be flexibly connected, and sleeve and leg base are dismountable, is installed on the equipment that needs to use, and easy to use, it is convenient to install.
2, the length of sleeve is equal to or greater than the height of leg base, and the leg base moves up and down in the process, is in all the time and the bush whorl connection status, and in the use procedure, the leg base can be because the external force reasons such as vibrations split away off, and the castor leg performance is more stable.
3, adopt the leg base of hemispherical dome structure, enlarged lifting surface area, the leg base is that steel is moulded tubing and made in addition, and load performance is very good, thereby applied widely.
4, universal wheel is combined with the leg base, have concurrently and support and mobile characteristics, when the leg base contacts with ground, can wrapping up universal wheel integral body, both avoided for a long time and the strain cracking that cause stressed in direction of universal wheel, prolonged the service life of universal wheel, the dust around guaranteeing again can not enter in the universal wheel wheel body, is conducive to universal wheel and safeguards.
Description of drawings
Fig. 1 is the structural representation of a kind of castor leg of the utility model.
Number in the figure: 1, leg pipe; 2, sleeve; 3, leg base; 31, inwall; 4, universal wheel.
The specific embodiment
Fig. 1 is a kind of castor leg of the utility model, comprise leg pipe 1, leg base 3 and universal wheel 4, universal wheel 4 is installed in the bottom of leg pipe 1, the bottom of leg pipe 1 is installed with sleeve 2, sleeve 2 adopts screw thread to be flexibly connected with leg base 3, leg base 3 is hemispherical dome structure, and the radius of the inwall 31 of leg base 3 is equal to or greater than the diameter of universal wheel 4, and the length of sleeve 2 is equal to or greater than the height of leg base 3.When needs moved, rotation leg base 3 made leg base 3 move up along sleeve pipe 2, until leg base 3 bottoms are above ground level, can use universal wheel 4; When not needing to move, rotatable leg base 3 makes leg base 3 move down along sleeve 2; leg pipe 1 is propped up, universal wheel 4 is not contacted with ground, leg base 3 is wrapped in its inside with universal wheel 4; when whole device is played the effect of support, also universal wheel 4 has been played protective effect.
The length of sleeve 2 is equal to or greater than the height of leg base 3, leg base 3 moves up and down in the process along sleeve 2, all the time be in and sleeve 2 screw threads flexible connection state, leg base 3 just can not split away off because of the reason of the external force such as vibrations like this, and the castor leg performance is more stable; Leg base 3 adopts spherical structure, enlarged lifting surface area, the steel that in addition adopts is moulded tubing, load performance is very good, when this castor leg does not need or time spent not, sleeve 2 and leg base 3 can be disassembled, be installed in the position that other need, convenient disassembly, it is convenient to install, applicable to a lot of fields.
Claims (4)
1. a castor leg comprises leg pipe, universal wheel and leg base, it is characterized in that: described leg pipe bottom is installed with sleeve, is flexibly connected by screw thread between sleeve and the leg base, and the leg base is hemispherical dome structure.
