Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 5, the present utility model provides a tension head, which includes:

the shell 1, two sides of the top of the shell 1 are provided with through holes 2;

a spring mechanism provided inside the housing 1 and composed of a fixed ring 3 and a spring 4;

a locking mechanism provided inside the housing 1;

the locking mechanism comprises a movable block 5, wherein the movable block 5 is movably arranged at the bottom of the inner wall of the shell 1, a side hole 6 is formed in the top of the inner wall of the movable block 5, steel balls 7 are movably arranged on the inner wall of the side hole 6, and the movable block 5 drives the three steel balls 7 to move downwards so that the three steel balls 7 are extruded to the center by the inner wall of the shell 1.

The lamp wire passes through the inner cavity of the movable block 5, the through hole 2 can pass through the bifurcation wire rope, and the movable block 5 is pulled to move downwards due to the action of gravity of the lamp, so that the movable block 5 drives the three steel balls 7 to move downwards, the steel balls 7 are extruded by the inner wall of the shell 1, and the three steel balls 7 gather towards the center of the inner cavity of the movable block 5.

The method comprises the following steps:

the spring mechanism, the surface of solid fixed ring 3 cup joints with the inner wall of casing 1 fixedly, and the one end fixed connection of spring 4 is at the top of solid fixed ring 3 inner wall, and the other end fixed connection of spring 4 is at the top of movable block 5.

By setting the spring 4 in an unstressed state, enough space is reserved between the movable block 5 and the inner wall of the shell 1 for the steel balls 7 to stay, so that the lamp wire can smoothly pass through the inner cavity of the movable block 5.

Wherein, the bottom of casing 1 inner wall is the slope form, and casing 1's inner wall is smooth.

By the smooth design of the inner wall of the shell 1, the movable block 5 can move more smoothly in the shell 1.

Wherein the number of the through holes 2 is two, the diameters of the two through holes 2 are the same, and the two through holes 2 are symmetrical about the center of the fixed ring 3. The housing 1 can be connected with the wire rope by passing the wire rope through the through hole 2 so as to be connected with the lamp subsequently.

Wherein, the inner wall of the side hole 6 is smooth, and the diameter of the inner side of the side hole 6 is smaller than the diameter of the steel ball 7.

By the effect that the diameter of the inner side of the side hole 6 is smaller than that of the steel ball 7, the steel ball 7 can be prevented from falling off from the inner cavity of the movable block 5 accidentally.

The number of the steel balls 7 is three, the sizes of the three steel balls 7 are the same, and the three steel balls 7 are uniformly distributed.

Through the design of three steel balls 7 evenly distributed, the stress is even when the lamp wire is clamped, and therefore the clamping effect is better.

The working principle and the using flow of the utility model are as follows:

when a user installs the lamp, the bifurcated steel wire rope can penetrate through the through hole 2, the lamp wire penetrates through the inner cavity of the movable block 5, the lamp is connected to the lower portion of the movable block 5, and the movable block 5 is pulled to move downwards and stretch the spring 4 due to the action of gravity, so that the movable block 5 drives the three steel balls 7 to move downwards, the steel balls 7 are extruded by the inner wall of the shell 1, the three steel balls 7 gather towards each other towards the center of the inner cavity of the movable block 5, the lamp wire inside the movable block 5 can be extruded and fastened, the lamp and the lamp wire can be fixed, the effect of reducing the lamp assembly is finally achieved, and accordingly the lamp assembly cost of the user is reduced.
