Description

Roll wheel assembly

Technical field

The utility model relates to roll wheel assembly, relates in particular to the roll wheel assembly of case and bag.

Background technology

Existing roll wheel assembly comprises holder, support, wheel, wheel is connected with support by a transverse axis, connect by a vertical pivot between support and the holder, the top of vertical pivot is fixedly connected with holder, the vertical pivot bottom rotatably cooperates with the axle installing hole that support is provided with an opening upwards, and the position on the axis direction of vertical pivot limits comparatively complexity of mechanism, and the assembling of roll wheel assembly integral body is comparatively loaded down with trivial details, production efficiency is low, and the vibrations when using along with whole roller make this position limit the loosening inefficacy of mechanism easily.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of roll wheel assembly simple in structure, easy for installation, well-set is provided.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such: a kind of roll wheel assembly comprises holder, support, wheel, wheel is connected with support by a transverse axis, connect by a vertical pivot between described support and the holder, the top of described vertical pivot is fixedly connected with holder, the vertical pivot middle and lower part is provided with annular notch, the vertical pivot bottom rotatably cooperates with the axle installing hole that support is provided with an opening upwards, the annular notch position of the corresponding vertical pivot of bracket side face middle and lower part is provided with bayonet lock installing port and grab, in the described bayonet lock installing port bayonet lock is installed, match with annular notch in the annular notch of the left end insertion vertical pivot of described bayonet lock, the right-hand member of bayonet lock cooperates with the grab clamping, and the upper wall butt of bayonet lock installing port cooperates on the upper end of bayonet lock and the support.

The beneficial effects of the utility model are: because in the above-mentioned technical solution, the annular notch position of the corresponding vertical pivot of bracket side face middle and lower part is provided with bayonet lock installing port and grab, and match with annular notch in the annular notch of the left end of bayonet lock insertion vertical pivot, the right-hand member of bayonet lock cooperates with the grab clamping, the upper wall butt of bayonet lock installing port cooperates on the upper end of bayonet lock and the support, first the related holder of vertical pivot is installed in the axle installing hole of support during assembling, match with annular notch in the annular notch with bayonet lock one end insertion vertical pivot again, at last with the other end of bayonet lock upwards extruding snap in the grab that support is provided with, this moment bayonet lock upper end and support on the upper wall butt of bayonet lock installing port cooperate, the lower end table top of grab and annular notch limits the movement of bayonet lock downward direction, the side face of cylinder of grab and annular notch limits the movement of bayonet lock left and right directions, therefore when bayonet lock is limited very securely, bayonet lock limits also very firm along the position on the axis direction to vertical pivot, so the roll wheel assembly that the utility model provides has simple in structure, easy for installation, well-set characteristics.

The specific embodiment

Below in conjunction with embodiment the utility model is described in further detail.

Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model provides a kind of roll wheel assembly to comprise holder 1, support 2, wheel 3, wheel 3 is connected with support 2 by a transverse axis 4, described support 2 and hold in the palm 1 between connect by vertical pivot 5, the top of described vertical pivot 5 is fixedly connected with holder 1, vertical pivot 5 middle and lower parts are provided with annular notch 7, vertical pivot 5 bottoms rotatably cooperate with the axle installing hole 6 that support 2 is provided with an opening upwards, annular notch 7 positions of corresponding vertical pivot 5 middle and lower parts, support 2 sides are provided with bayonet lock installing port 8 and grab 9, in the described bayonet lock installing port 8 bayonet lock 10 is installed, match with annular notch 7 in the annular notch 7 of the left end insertion vertical pivot 5 of described bayonet lock 10, the right-hand member of bayonet lock 10 cooperates with grab 9 clampings, upper wall 11 butts of bayonet lock installing port 8 cooperate on the upper end of bayonet lock 10 and the support 2, whole installation process is very simple and convenient, to ask first 1 to be connected connection with vertical pivot, again vertical pivot 5 is packed into axle installing hole 6 on the support 2, the bayonet lock installing port 8 of at last bayonet lock 10 being packed into, therefore this roll wheel assembly has simple in structure, easy for installation, well-set characteristics.

Such as Fig. 1, Fig. 2, shown in Figure 3, described bayonet lock 10 is provided with round-corner transition 10-1 with the end that cooperates of grab 9, this structure can make things convenient for bayonet lock 10 extruding to snap in grab 9, in order to further facilitate installation, the round-corner transition 10-1 that matches with grab 9 all can be processed in the two ends, the left and right sides of bayonet lock 10, such structure is more convenient at installation bayonet lock 10, and the material of bayonet lock 10 is also more saved simultaneously.

As shown in Figure 4, the another kind of embodiment that the utility model provides, described bayonet lock 10 is provided with oblique angle transition 10-2 with the end that cooperates of grab 9, this structure can make things convenient for bayonet lock 10 extruding to snap in grab 9, in order to further facilitate installation, the two ends, the left and right sides of bayonet lock 10 all can be processed into the oblique angle transition 10-2 that matches with grab 9, such structure is more convenient at installation bayonet lock 10, and the material of bayonet lock 10 is also more saved simultaneously.

Better for the fastness that makes bayonet lock 10, bayonet lock 10 is preferably metal material.
