Abstract

An end fixing device for a foldable tent, which is used to connect a set of foldable supporting rods and auxiliary rods to form a tent bracket, is substantially composed of a hydraulic rod and an extension member. One end of the hydraulic rod is secured to a connection member which is used to pivot with each auxiliary rods, and the other end is fixed to the extension member which is used to pivot with each foldable supporting rod. The foldable supporting rods and the auxiliary rods are unfolded and supported by virtue of the thrust force from the hydraulic rod. This device has a simple structure, and is easy to manufacture, assemble and operate.

Description

A top fixing device for a folding tent Technical Field The present invention relates to components of travel or camping supplies, and in particular, to a top fixing device for a folding tent. BACKGROUND OF THE INVENTION In the prior art, there is a top fixing device structure for a folding tent, as shown in Figures 1 and 2. It is connected to a set of foldable poles 1 and auxiliary poles 5 to form a tent support, which is mainly composed of support poles 2 , , spring 3, expansion frame 4, and baffle 6, composed of support rod 2, the upper end of which is fixed with each auxiliary support rod 5 pivotally connected, the connecting nest 21, and the other end of each auxiliary support rod 5' is pivotally connected The upper and lower parts of the support rods 1 and 2 are provided with springs 3 in turn, and are pivotally connected to the expansion frames 4 of each foldable support rod 1, and a baffle 6 is fixed through a pin 62; An elastic protruding card 7 is also fixed at the lower part of the support rod 2, and a clamping hole 41 is provided at the lower part of the expansion frame 4'. The elastic protruding card 7 can be inserted into the carding hole 41 due to the elastic effect, so that the expansion frame 4' can be opened. The expansion frame 4' is positioned on the support rod 2'.

When folding the tent with this structure, you only need to lightly press the elastic protruding clip 7 in the expansion frame 4 and the clip hole 41 to release the elastic clip 7 and the clip hole 41. , with the clamping effect, push the expansion frame 4' to slide upward relative to the support rod 2, and each foldable support rod 1 will be folded together due to the disappearance of tension, making the folding operation easy.

In the folded state of the tent, the expansion frame 4 is always moved upward toward the connection nest 21 due to the elastic tension of the spring 3, causing the position of the expansion frame 4 to be higher.

When unfolding the tent, it is necessary to overcome the elastic tension of the spring 3, and pull the expansion frame 4' downward to the elastic protrusion 7, and the clamping hole 41 to form a lock, and then the auxiliary support pole 5 can be driven with the help of the connecting nest 21. And pull out the foldable support pole 1. However, in order to overcome the elastic tension of the spring 3 and pull the expansion frame 4 which is relatively high, this action requires a large force for the user, and the operation is slightly inconvenient. For smaller users, For example, you need to stand on tiptoe to reach the expansion rack 4, or even cannot reach the expansion rack 4, so that the tent cannot be deployed, so the deployment operation is inconvenient.

Moreover, the top fixing device of this structure has many components, has a complicated structure, and is inconvenient to process and assemble. SUMMARY OF THE INVENTION The object of the present invention is to provide a top fixing device for a folding tent, which has fewer components, a simple structure, is easy to process and assemble, and makes the unfolding operation of the tent more convenient and labor-saving. In order to achieve the above objectives, the solution of the present invention is:

The top fixing device of the folding tent is connected to a set of foldable poles and auxiliary poles to form a tent support. It is mainly composed of a hydraulic pole and an expansion frame. One end of the hydraulic pole is fixed to the connection for pivoting each auxiliary pole. On the nest, the other end of the hydraulic rod is fixed on the expansion frame for pivotally connecting the foldable struts. With the support of the hydraulic rod, the fixed auxiliary struts and the foldable struts are expanded.

A groove is formed below the above-mentioned expansion frame to facilitate pushing and pulling force.

After adopting the above structure, the present invention uses hydraulic rods instead of support rods, springs, baffles and other components to be arranged between the expansion frame and the connecting nest. It has fewer components, a simple structure, and is easy to process and assemble.

In the unfolded state of the tent, the expansion frame is always pushed downward by the hydraulic rod, and the auxiliary poles and foldable poles remain in the expanded state; when you want to fold the tent, push the expansion frame upwards , driving the center of each foldable pole to move upward, bringing each auxiliary pole and each foldable pole closer together, and then using ropes to tie up each auxiliary pole and each foldable pole of the tent, thus completing the folding of the tent. When you want to unfold the tent, untie the tied ropes, and the expansion frame will be pushed downward by the support of the hydraulic rod. The center of each foldable pole will also move downward through the expansion frame, even if each foldable pole is folded. The auxiliary support pole and each foldable support pole are unfolded, and the unfolding operation is very convenient and labor-saving.

DETAILED DESCRIPTION OF THE INVENTION The top fixing device of the folding tent disclosed in the present invention is suitable for folding tents like conventional items. It connects a set of foldable poles 1 and auxiliary poles 5 to form a tent support.

As shown in Figure 3, the present invention mainly consists of a hydraulic rod 2 and an expansion frame 3. Among them, the hydraulic rod 2 is an existing product, and its structure will not be described in detail here. It mainly includes an outer tube 21 and an inner rod 22 that are nested with each other. One end of the hydraulic rod 2 (shown in the figure is the outer tube 21) is fixed on the connecting nest 4 for pivoting each auxiliary support rod 5, and the other end of the hydraulic rod 2 (shown in the figure is the inner rod 22) is fixed on It is used to pivot the expansion frame 3 of each foldable strut 1. With the support of the hydraulic rod 2, the expansion frame 3 is always pushed downward, and each auxiliary strut 5 and each foldable strut 1 are kept in place. expanded state. When you want to fold the tent, push the expansion frame 3 upward to drive the center of each foldable pole 1 to move upward, that is, each auxiliary pole 5 and each foldable pole 1 are close to each other, and then use ropes (not shown in the figure) (shown in Figure 5) Bundle the auxiliary poles 5 and the foldable poles 1 of the tent to complete the folding of the tent, as shown in Figure 5.

When the tent is to be unfolded, the tied ropes are untied, and the expansion frame 3 is pushed downward by the support of the hydraulic rod 2. The center of each foldable pole 1 is also moved downward through the expansion frame 3. Even if each auxiliary strut 5 and each foldable strut 1 are unfolded, as shown in Figure 4, the unfolding operation is very convenient and labor-saving.

In short, the key to the present invention is to use the hydraulic rod 2 to replace the support rod 2, spring 3, and baffle 6 in the prior art. The components such as the expansion frame 3 and the connecting nest 4 are arranged between the expansion frame 3 and the connecting nest 4. The overall components are significantly reduced. The structure is simpler, processing and assembly are more convenient, and the tent unfolding operation is very convenient and labor-saving.
