Abstract

A quick-connection support tube comprises an upper tube and a lower tube, and is characterized in that the support tube further comprises a connecting device for demounting and connecting the upper tube and the lower tube; a ring-shaped supporting bulge and a draft tube penetrating the upper tube wall are formed on the outer surface of the lower part of the upper tube; a guide groove and a guide positioning groove communicated with the guide groove are formed at the upper end of the lower tube; the connecting device mounted in the upper tube can fixedly connect the upper tube and the lower tube; and the upper end of the lower tube is in fit with the ring-shaped supporting bulge. By adopting the structure, the connecting device is mounted in the draft tube of the upper tube, when the upper tube and the lower tube are required to be connected, a left and a right pressing ends of the connecting device enter the guide positioning groove via the guide groove on the lower tube, then, the upper tube or the lower tube is rotated, so as to fixedly connect the upper tube and the lower tube; and when upper tube and the lower tube are required to be demounted, the upper tube or the lower tube is rotated, then, the left and the right pressing ends are pressed simultaneously, and the left and the right pressing ends enter the guide groove, so as to separate the upper tube and the lower tube. Therefore, the support tube can be fixedly connected effectively and be demounted, connected and mounted conveniently.

Description

The quick stay pipe that connects

Technical field

The utility model relates to the stay pipe that a kind of floor lamp, flooring fan are used, especially a kind of stay pipe of quick connection.

Background technology

Present prior art, Chinese patent ZL03216166.2, invention and created name: the improvement of stay pipe structure, it comprises that stay pipe one, two, two stay pipes of stay pipe connect by the connector of dribbling head, stay pipe one, two rotates relatively.Existing problems are: inconvenience is dismantled, is connected and installed to stay pipe one, two.

Summary of the invention

The purpose of this utility model is: a kind of quick connecting pipe is provided, and it can be fixedly connected effectively, and dismantles, is connected and installed conveniently.

The utility model is achieved in that a kind of stay pipe of quick connection, it comprises pipe, manages down, its special character is: also comprise one with the detachable jockey that connects of upper and lower pipe, the described outer surface of going up the pipe bottom, the annular brace projection is arranged, connect the guide pipe of upper tube wall; Described down pipe upper end have symmetrically arranged gathering sill, with edge that gathering sill communicates under the guide-localization groove of tube wall; Jockey is installed in the pipe, passes guide pipe, the guide-localization groove is fixedly connected upper and lower pipe, and the upper end of following pipe cooperates with the annular brace projection.

The stay pipe of described quick connection, its special character is: described jockey is made of left screens pin, right screens pin, limiting plate and compression spring; Described left screens pin is made of the left guide way of left head, hollow, on the left guide way draw-in groove is arranged, and limiting plate is installed in the draw-in groove; Described right screens pin is made of right head, right guide way and guide post, in draw-in groove, the draw-in groove limiting plate is installed on the right guide way; Compression spring is installed in the left guide way cavity, and guide post inserts in the cavity; Left and right screens pin is installed in the pipe, and left and right guide way inserts in the guide pipe, and left and right head inserts in the guide-localization groove of following pipe.

The utility model quick connecting pipe, owing to adopt such structure, jockey is installed in the guide pipe of pipe, when the upper and lower pipe of needs connects, gathering sill under the left and right head warp of jockey on the pipe, enter the guide-localization groove, and then rotation is managed upward or following pipe, upper and lower pipe can be fixedly connected; When needs are dismantled, pipe or following pipe in the rotation, simultaneously by left and right head, left and right head enters gathering sill then, realizes that upper and lower pipe separates.So it can be fixedly connected effectively, and dismantle, be connected and installed conveniently.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, a kind of stay pipe of quick connection, it comprises pipe 1, manages 2 down, also comprises one with upper and lower pipe 1, the 2 detachable jockeys that connect, and the described outer surface of going up pipe 1 bottom, annular brace projection 11 is arranged, and connects the guide pipe 12 of upper tube wall;

As Fig. 2, Fig. 3, shown in Figure 4, the following guide-localization groove 22 of managing 2 walls in edge that there is symmetrically arranged gathering sill 21 described following pipe 2 upper ends, communicates with gathering sill 21; Jockey is installed in the pipe 1, passes guide pipe 12, guide-localization groove 22 is fixedly connected upper and

lower pipe

1,2, and following 2 upper end and the annular brace projection 12 of managing supports mutually.

Described jockey is made of left screens pin 3, right screens pin 4, limiting plate 5 and compression spring 6;

Left as described in Figure 5 screens pin 3 is made of the left guide way 32 of left head 31, hollow, on the left guide way 32 draw-in groove 7 is arranged, and limiting plate 5 is installed in the draw-in groove 7; As shown in Figure 6, described right screens pin 4 is made of right head 41, right guide way 42 and guide post 43, has on the right guide way 42 in draw-in groove 7, the draw-in groove 7 limiting plate 5 is installed; Compression spring 6 is installed in left guide way 32 cavitys 33, and guide post 43 inserts in the cavity 33 and cooperates with compression spring 6; Left and

right screens pin

3,4 is installed in the pipe 1, and left and

right guide way

32,42 inserts in the guide pipes 12 and is slidingly matched with guide pipe 12, and left and

right head

31,41 inserts in the guide-localization groove 22 of pipe 2 down.Because the effect of limiting plate 5, compression spring 6, limiting plate cooperates with the end of guide pipe 12, and jockey is remained in the pipe 1.

As shown in Figure 1, left and

right head

31,41, be in by gathering sill 21, just entered the state of guide-localization groove 22, the direction of arrow manages 1 in the rotation as shown in Figure 2, and left and
