The universal/directional reversing caster is simple in structure and reliable, flexible and convenient to open and close, integrates directional and universal functions, and is particularly suitable for stretcher front caster.

Description

Universal/directed conversion castor

Technical field

The present invention relates to a kind of stretcher universal caster wheel, be specifically a kind of can be universal/the stretcher castor of directed conversion.

Background technology

The stretcher generally using at present, a part adopts direction-caster, can only straightaway while normally carrying out, turn round very constant.Present stretcher is most, and to adopt front truckle be universal caster wheel, and it turns to very convenient, but direct of travel very easily changes, and therefore keeps straight on very difficult.That is to say the front truckle of existing stretcher or be directed or for universal, simultaneously compatible orientation and gimbal function.Be unfavorable for the single craspedodrome of some specific environment needs or direction movement function.

Utility model content

Technical problem to be solved in the utility model, is to overcome the defect that prior art exists, and has proposed a kind of universal/directed conversion castor, and compatible orientation and gimbal function, be particularly useful for Medical stretcher simultaneously.

A kind of universal/directed conversion castor of this utility model, comprise lower limb bar and the universal portal trestle that is arranged on lower limb bar bottom, it is characterized in that: the top of universal portal trestle is provided with draw-in groove, on the lower limb bar above universal portal trestle, be provided with adapter sleeve, the sidepiece of adapter sleeve is provided with orientation lock;

The lock body of described orientation lock is provided with vertical lockhole, spring and locking bar; Described lock body upper end is offered orientation lock and is opened retaining groove and close retaining groove, and the degree of depth of closing retaining groove is greater than out the degree of depth of retaining groove, opens retaining groove and closes retaining groove Jun Yu lockhole UNICOM; The lower semisection aperture of lockhole is widened, and forms spring cavity; Described locking bar, upper end is provided with switchboard, and bottom is provided with spring baffle ring; Locking bar penetrates lockhole, and spring housing is on locking bar, and the spring baffle ring of locking bar is positioned at the below of spring, and spring is positioned at the spring cavity of lockhole; Locking bar and draw-in groove position are adaptive.

This utility model, simple in structure, switch is reliable and flexible, and compatible orientation and gimbal function are especially applicable to Medical stretcher front truckle.

The specific embodiment

Below in conjunction with drawings and Examples, this utility model is described in further details.

As shown in Figure 1, 2, universal/directed conversion castor, comprises lower limb bar 1 and the universal portal trestle 2 that is arranged on lower limb bar bottom, it is characterized in that: the top of universal portal trestle is provided with draw-in groove 3, on the lower limb bar above universal portal trestle, be provided with adapter sleeve 4, the sidepiece of adapter sleeve is provided with orientation lock 5.

The lock body of described orientation lock 5 is provided with vertical lockhole 6, spring 7 and locking bar 8; Described lock body upper end is offered orientation lock and is opened retaining groove 9 and close retaining groove 10, and the degree of depth of closing retaining groove is greater than out the degree of depth of retaining groove, opens retaining groove and closes retaining groove Jun Yu lockhole UNICOM; The lower semisection aperture of lockhole is widened, and forms spring cavity 11; Described locking bar 8, upper end is provided with switchboard 12, and bottom is provided with spring baffle ring 13; Locking bar penetrates lockhole, and spring housing is on locking bar, and the spring baffle ring of locking bar is positioned at the below of spring, and spring is positioned at the spring cavity of lockhole; Locking bar and draw-in groove position are adaptive.

When needs universal rotational, switchboard 12 is pulled out to retaining groove 9, on locking bar, to carry, wheel can universal rotational.When needs are directly to when motion, switchboard 12 to be pulled and closed retaining groove 10, locking bar falls, and promotes wheel, and in the process swinging at wheel, the bottom of locking bar can be inserted in draw-in groove, and locking wheel keeps keeping straight on.
