Detailed Description

In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

Example 1:

a foldable and telescopic tricycle hood is shown in figures 1-3 and comprises a hood frame and a hood cloth covering the hood frame. The covering or awning on a car, boat, etc. frame includes guide rail 1, brace rod 2 and telescopic connecting rod 3, and guide rail 1 is installed on the both sides frame handrail of tricycle frame, and brace rod 2 is parallel to each other to brace rod 2 is installed in proper order on guide rail 1 by preceding to back and is formed the covering or awning on a car, boat, etc. frame, connects through alternately articulated telescopic connecting rod 3 between two adjacent brace rods 2, and the lower part of brace rod 2 can be followed guide rail 1 and removed and drive telescopic connecting rod 3 and stretch out and draw back and then adjust the longitudinal length of whole covering or awning on a car, boat, etc. frame. In this embodiment, all install telescopic link 3 in the left side of brace rod 2, right side and upper end, telescopic link 3's central cross point is articulated with brace rod 2, and at the in-process of indulging push-and-pull brace rod 2 along the frame, telescopic link 3's contained angle will change to distance between two adjacent brace rods 2 will also change, thereby realize the expansion and the folding of whole covering or awning on a car, boat, etc. frame.

Wherein, the support rib 2 is in a reversed U shape, and the tarpaulin covers the outer side of the support rib 2. In this embodiment, the brace rod 2 includes that two son of "L" type side prop 21, and two son prop 21's upper end through the activity of the flexible cover 4 activity of horizontal cup joints (the flexible cover 4 of horizontal position can be located the center of brace rod, perhaps the position of left side or right side partially), and then can adjust the horizontal width of whole covering or awning on a car, boat, etc. frame through adjusting the flexible cover 4 of horizontal like this to be adapted to the use of different width tricycles. The horizontal telescopic sleeve 4 comprises a square sleeve 41 and an inner sleeve tongue 42 which can be sleeved with each other, the end of one of the sub-struts 21 is provided with the square sleeve 41, the end of the other sub-strut 21 is provided with the inner sleeve tongue 42, the inner sleeve tongue 42 can extend into the direction sleeve 41, and the length of the horizontal telescopic sleeve 4 is adjusted by adjusting the length of the inner sleeve tongue 42 extending into the direction sleeve 41, so that the width of the support rib 2 is adjusted. A row of screw holes are correspondingly formed on the square sleeve 41 and the inner sleeve tongue 42 respectively, and after the length is adjusted, the adjusting bolt 43 is screwed into the screw holes, so that the square sleeve 41 and the inner sleeve tongue 42 are fixedly connected.

In order to reduce the friction between the support bar 2 and the guide rail 1, the push-pull resistance is reduced. The lower end of the support rib 2 is provided with a connecting base 5, and the support rib 2 is arranged in the guide groove of the guide rail 1 through the connecting base 5. The connecting base 5 comprises a central shaft 51, a rolling bearing 52 and a friction disc 53, wherein the central shaft is vertically arranged, the rolling bearing 52 is sleeved on the central shaft, the friction disc 53 is installed at the lower end of the central shaft, and the outer wall of the rolling bearing 53 is in rolling contact with the inner wall of the guide groove of the guide rail 1; the lower end of the friction disc 53 is a spherical surface, and the lower end of the friction disc 53 is in sliding contact with the bottom of the guide groove of the guide rail. In the process of pushing and pulling the support rib 2 along the longitudinal direction of the guide rail 1, the rolling bearing 53 rolls along the inner wall of the guide rail 1, and simultaneously, the spherical surface at the lower end of the friction disc 53 slides along the bottom of the guide rail 1, so that the sliding friction between the lower end of the rolling bearing 53 and the guide rail 1 is avoided, and the sliding resistance and the noise are reduced.

In addition, the upper section of the center shaft 51, that is, the portion of the center shaft 51 not fitted into the guide rail 1, is designed as a threaded rod section, a compression nut 54 is fitted over the threaded rod section, a limit washer 55 is provided below the compression nut 54, and a compression spring 56 is fitted over the center shaft between the limit washer 55 and the rolling bearing 53. Before the longitudinal length of the tent frame is adjusted, the compression nut 64 is unscrewed, at the moment, the friction force between the limiting gasket 66 and the upper end face of the guide rail 1 is gradually reduced to disappear, meanwhile, the limiting of the compression spring 56 on the rolling bearing 53 is also disappeared, at the moment, the rolling bearing 53 can roll along the inner wall of the guide rail 1, and the central shaft 51 can move relative to the guide rail 1. After the longitudinal length of the roof frame is adjusted to a proper position, the compression nut 54 is screwed, at this time, the limiting gasket 55 is limited on the upper end surface of the guide rail 1 by the compression nut 54, the rolling bearing 53 is also limited by the compression spring 56, at this time, the central shaft 61 can not move relative to the guide rail 1, namely, the whole roof is fixed on the frame.

But be provided with magic subsides 6 that can bond each other on the outer wall of brace rod 2 and on the inner wall of tarpaulin respectively, paste 6 through the magic between brace rod and the tarpaulin and be connected, the design that the magic was pasted for tie up with the rope among the prior art, dismantles and operates more easily.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent replacement and modification or partial replacement that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the present invention.
