Abstract

The utility model relates to a length-adjustable telescopic besom which comprises a besom handle and a cleaning block. The difference is that the besom handle comprises an upper pipe and a lower pipe. The female screw of the upper pipe is engaged with the male screw of the upper part of the lower pipe. The male screw of the lower part of the upper pipe is engaged with female screw of the clamping cover. The lower part of the clamping cover is a wedge mechanism which is allocated with an access slit cuneiform of the lower part of the upper pipe. The access slit cuneiform has four access slits. The surfaces of the upper pipe and the lower pipe are provided with reflecting coats. The utility model has the advantages of simple structure, convenient use and continuous adjustment of the besom length.

Description

Telescopic besom

Technical field

But the utility model relates to a kind of telescopic besom of free adjustment length.

Background technology

At present, the besom of Shi Yonging is fixing length generally in daily life, and can not change the length of besom, or the mode that adopts pin to connect, two bars at besom are opened a round, come the length of besom is regulated by the cooperation that changes pin hole, but this regulative mode just is spaced a distance and regulates, can not realize successional adjusting length.Therefore, for the people of different heights, it is very difficult need finding the besom that is fit to own height fully.

Summary of the invention

Problem to be solved in the utility model is to propose a kind of telescopic besom at above-mentioned prior art, and its length that can realize besom is regulated continuously.

The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: a kind of telescopic besom, include besom bar and cleaning piece, its difference is that the besom bar is made up of top tube and down tube two parts, and the internal thread that last pipe is provided with cooperates with external screw thread on the pipe down.

Press such scheme, the screw-internal thread fit that is provided with on the external screw thread that described upward pipe lower end is provided with and the gripping sleeve in the last pipe outside.

Press such scheme, described gripping sleeve bottom is the wedge structure, the gap wedge phase configuration of itself and last pipe lower end, and described gap wedge contains four gap.

Press such scheme, described top tube and down tube surface is provided with reflecting coating.

Free-revving engine of the present invention is, consider the demand of the people of different heights to the different length besom, the besom bar of besom is made upper and lower two parts, adopt the connecting mode of extension type, bond them together, thereby reach the purpose of free adjustment besom length, to be applicable to different height crowds.

Advantage of the present utility model:

1, simple in structure, easy to use.

2, can regulate the length of besom continuously.

Description of drawings

Fig. 1 is the structural representation of telescopic besom of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is further described in detail.

As shown in Figure 1, telescopic besom, include besom bar 8 and cleaning piece 3, the besom bar is made up of last pipe 7 and following pipe 4 two parts, the internal thread 1 that last pipe is provided with cooperates with the external screw thread 2 of pipe upper end down, on manage the internal thread 5 that is provided with on the gripping sleeve outside external screw thread 6 that the lower end is provided with and the last pipe and cooperate.Described gripping sleeve bottom is the wedge structure, the gap wedge phase configuration of itself and last pipe lower end, and described gap wedge contains four gap.When needs are regulated besom length, can earlier gripping sleeve be unscrewed, turn down pipe again, when reaching required length, stop to twist, again gripping sleeve is tightened.At this moment, the connection of two pipes is tight up and down, is difficult for loosening.By above method, can satisfy the length requirement of different height personages to besom.Can be coated with the last layer reflecting coating at two tube-surfaces up and down in addition, when light was radiated at its surface, reflecting coating played reflection ray caution and reminds other people effect.

Claims

1, telescopic besom includes besom bar (8) and cleaning piece (3), it is characterized in that the besom bar by last pipe (7) and down pipe (4) two parts forms, the external screw thread (2) on internal thread (1) that last pipe is provided with and following the pipe cooperates.

2,, it is characterized in that the internal thread (5) that is provided with on the described gripping sleeve of going up outside external screw thread (6) that the pipe lower end is provided with and the last pipe cooperates by the described telescopic besom of claim 1.

3, by the described telescopic besom of claim 2, it is characterized in that described gripping sleeve bottom is the wedge structure, the gap wedge phase configuration of itself and last pipe lower end, described gap wedge contains four gap.

4, by claim 1 or 2 or 3 described telescopic besoms, it is characterized in that described top tube and down tube surface is provided with reflecting coating.
