Description

A double pole structure for improving the stability of tent support poles

technical field

The utility model belongs to a support mechanism for a tent, in particular to a tent with a reinforced support structure.

Background technique

Tents are important equipment for travel, commercial promotional activities, field camping, open-air leisure and other activities. The main functions of tents are windproof, rainproof, dustproof, sunscreen, dewproof, and moisture-proof, providing a relatively comfortable environment for the outdoors. . According to the purpose of use, the following factors should be considered in the selection of tents: choose the outer tent to strive for high water resistance, you can blow the fabric with your mouth to test its air permeability, generally poor air permeability, good water resistance. Choose the inner tent and strive for good air permeability. Choose struts for high strength and good resilience. The choice of base material should pay attention to water resistance and wear resistance. It is best to choose a double-layer structure for camping and camping tents. It is best to choose the size with a door shed, or consider a slightly larger size. Choosing a tent with front and rear double doors is more conducive to ventilation. Although the use of tents is not complicated, it is also a science. The same tent, if used properly, will have good windproof and rainproof effects, and vice versa.

For the structure of the tent, the main structure of the most commonly used outdoor folding tent is a frame and a top cloth. The frame generally has support legs, side wall pipes, and top cloth supports.

The structure of the tent top cloth support member in the prior art is roughly divided into two types. The top of the first type is arranged diagonally as shown in Figure 4, and the four jacking pipes are inclined upward to the center. It is slippery, which is beneficial for rainwater to slide down and does not accumulate water. The structure is simple and cost-effective, but the overall stability of the product is poor. The second type of jacking pipe is composed of two sets of cross-shaped pipes, as shown in Figure 5, with a central rod in the middle. When the tent is opened, the central rod lifts the top cloth under the lifting of the cross rod and supports the top cloth. role. This support structure has a complex structure, uses more materials, and costs quite high. Therefore, most of them still use the first type of pipe jacking structure. The specific structure of this type of tent is that the four sides are four vertical poles, and the two sides are composed of three sets of upper and lower side wall cross pipes. The upper side wall cross pipe at the end is hinged at the upper corner, the lower side wall cross pipe can be fixed or slid along the vertical pole, and the four corners are respectively hinged with four jacking pipes, which are hinged at the center when they are stretched out. The tent structure is like a square pavilion. After use, it can be folded into a bundle of pipes and rods, and the pipes and rods can be stretched. The overall volume becomes small and easy to carry. However, the disadvantage of poor overall stability of this type of structure after support is that it is urgent to have measures for improvement and improvement.

Contents of the invention

The purpose of the utility model is to provide an improved structure of a tent support pole, so as to achieve the purpose of improving the stability of the tent support pole. The purpose of this utility model is achieved by the following technical solutions.

A double-pole structure that improves the stability of tent support poles. The four corners of the tent are four vertical poles, and there are three sets of upper and lower side wall intersecting tubes that are crossed and rotated between each other, and the upper side wall intersecting tubes at both ends Hinged at the upper top corner, the lower side wall cross pipe can be fixed or slide along the pole, the four upper top corners are respectively hinged with the lower ends of the four jacking pipes, the upper ends of the four jacking pipes are inclined upward, and are hinged at the two opposite corners on the top of the tent The intersection of connecting lines is characterized by:

Hinge the lower ends of a support rod at the oblique joints of two adjacent lower side wall cross pipes at each corner, and the upper ends of the two support rods are both inclined upwards, hinged at the U-shaped joint at the same position of the corner top pipe , form two adjacent symmetrical and identical spatial quadrilaterals.

Further, the length of the support bar is equal to the distance from the upper top corner of 0.8-1.2 to the U-shaped joint, and is also equal to the distance of 0.8-1.2 from the connection point of the cross pipe of the lower side wall to the vertical pole to the oblique joint.

With this technical solution, when the tent is stretched, the four vertical poles are erected, and the three sets of upper and lower side wall intersecting tubes are also crossed and pulled apart, and the lower side wall intersecting tubes slide down along the vertical poles and are locked. , the four top pipes are tilted against the intersection of the four lower top corners and the two diagonal lines on the top of the tent to form a rectangular frame, at the oblique joints of the two adjacent lower side wall crossing pipes at each corner The lower ends of one support rod are respectively hinged, and the upper ends of the two support rods are all inclined upwards, and are hinged at the U-shaped joint at the same position of the angle jacking pipe to form two adjacent symmetrical and identical space quadrilaterals, which is better than the structure of the prior art The rigidity between the vertical pole, the upper side wall cross pipe, the lower side wall cross pipe, the jacking pipe and the support pipe is greatly strengthened, and the overall stability of the tent is improved.

The advantages of the utility model: the structure of the technical scheme is simple, and only two support rods are added at each corner, which has the effect of improving and reinforcing the rigidity of the corner, and can make the structure of the tent simple, high in stability and economical in cost , The structure of the technical solution does not affect the compact volume after being folded, and still maintains the advantage of being easy to carry.

Detailed ways

Below in conjunction with embodiment, the present invention is described in further detail and completely:

A double pole structure that improves the stability of tent support poles. The four corners of the tent are four vertical poles 5, and there are three sets of upper and lower side wall cross pipes 3 and 4 that are crossed and rotated to connect each other. The cross pipe 3 of the upper side wall is hinged on the upper corner 8, the cross pipe 4 of the lower side wall can be fixedly connected or slid along the vertical rod 5, and the four upper corners 8 are respectively hinged to the lower ends of the four jacking pipes 1, and the four jacking pipes 1 The upper end is inclined upwards and is hinged at the intersection of the two diagonal lines on the top of the tent. The lower end of a support rod 2 is respectively hinged at the oblique joint 7 of the two adjacent lower side wall cross pipes 4 at each corner. The upper ends of the rods 2 are all inclined upwards, and are hinged to the U-shaped joint 6 at the same position of the corner top pipe 1, forming two adjacent symmetrical and identical space quadrilaterals. Under the action of the intersecting pipe 3 on the upper side wall, the two symmetrical space quadrilaterals approximate to four triangles, which provide very strong rigidity.

The length of the support rod 2 is equal to 0.8-1.2 the distance from the upper corner 8 to the U-shaped joint 6, and also equal to 0.8-1.2 the distance from the connection point between the lower side wall cross pipe 4 and the vertical rod 5 to the bevel joint 7. In the above-mentioned size range, better-shaped quadrilaterals and triangles can be formed locally, and the stabilizing effect of the triangle can be exerted, so that the whole can achieve better support, rigidity and effect.
