Description

A labor-saving lifting structure of a tent

technical field

The utility model relates to the improvement of the internal structure of a tent, in particular to a lifting structure of a tent.

Background technique

As we all know, in field work or travel, tents or simple movable houses are indispensable facilities. When they are used, the earth is used as a bed, and they are usually required to be light in weight, small in size, and windproof and rainproof. With the rise and development of self-driving tours at home and abroad, there are new requirements for this. The tents in the prior art are simple in design and easy to carry. When supporting the tent, you only need to use simple poles to prop up the shape of the tent and then cover the poles with tent cloth. Therefore, it is suitable for mountaineering, field exploration and other harsh environments. case use. When carrying out leisure travel such as highly entertaining self-driving tours, the comfort of this kind of tent is relatively poor, and even needs to be built by oneself, and it is not convenient to use.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in accompanying drawings 1, 2, and 3, a labor-saving lifting structure of a tent includes a bracket and a transmission mechanism arranged on the bottom plate 1 of the tent. The transmission mechanism includes a main screw 3 fixed on one side of the bottom plate 1. One end of the main screw 3 is provided with a rocker 4, and the transmission between the rocker 4 and the main screw 3 is realized through the intermeshing driving gear 5 and the driven gear 6 respectively placed on the two; Two intersecting oblique rods 2 are formed, one end of the oblique rod 2 is hinged to the screw nut 8 on the main screw rod 3, and the other end is hinged to the tent top cover. The rocker 4 includes a short shaft 41 and a rocker 42 sleeved at the end of the short shaft, the driving gear 5 is assembled on the short shaft 41, and the short shaft 41 is fixed on the base plate 1 through the bearing seat 10; The driven gear 6 is assembled on the end of the main screw mandrel 3 . The driven gear 6 is a reduction gear, and its outer diameter is larger than that of the driving gear 5 .

The rocker 42 is arranged on the outside of the tent, and is set on the short shaft 41 of the bearing seat 10 through the preset grommet 13. The rotation drives the driving gear 5 on the short shaft 41 to rotate in the same direction, and the driving gear 5 rotates through the rotation. It drives the driven gear 6 to rotate in reverse, and the driven gear 6 drives the main screw 3 to rotate, and the main screw 3 drives the screw nut 8 on it to move left and right, so that the bracket 2 rises or falls, thereby driving The top cover is raised or lowered. In the utility model, the large gear is driven by the small gear, and the speed of rising or falling of the top cover is slowed down by using the gear transmission ratio principle, thereby achieving the purpose of labor saving.
