Description

Top frame of folding tent < RTI ID = 0.0 >

The present invention relates to the field of tent technology, and more particularly to the upper frame of a folding tent.

The folding type tent is composed of a foldable frame and a tent cloth, and the tent cloth is hooked to the frame, and the folding type frame is composed of a sub support which is distributed radially with the main support. The sub support is hinged to the main support via a hinge connecting member, and the folding frame is similar to the umbrella frame structure in the unfolded state and is also called an umbrella-type frame. A Chinese utility model patent CN200420044877.2 discloses an upper fixing device for a folding tent, which comprises a foldable support and a sub support to form a tent frame and is mainly composed of a support column, a spring, an extension frame and a stop member . At the upper end of the support column, a connection nest pivotally connected to each sub support is fixed. At the lower part of the support column, a spring and an extension frame pivotally connected to each support capable of pivoting are successively fitted and the stop member is fixed. An elastic protrusion jaw is fixed to the lower part of the column, a locking hole is formed in the lower part of the expansion frame, and the elastic protrusion jaw is elastically caught by the locking hole to fix the expansion frame to the supporting column. In the case of folding and reaping, it can be realized simply by pressing the elastic protruding jaw to release the engagement with the engaging groove. The device keeps the tent in a deployed state stably, and has a large space in the tent, which is convenient to unfold and fold. However, the upper fixing device of the folding type tent is required to press the elastic protruding jaws horizontally when folded and retracted. Such an operation is difficult because the elastic protruding jaws are small, The supporting post is likely to come into contact with the inside of the expansion frame when the elastic protruding jaw is pushed, resulting in wear and deformation of the parts, and the tent can not be folded.

The object of the present invention is to provide an upper frame of a folding tent that is simple in structure and is convenient and difficult to fold and store the tent.

In order to achieve the above object, a solution according to the present invention is as follows:

The upper frame of the folding type tent includes a main support, a supporting column, a spring, a connecting member, and a sub support, a connecting nest is fixed to the upper end of the supporting column, a stop member is fixed to the bottom of the supporting column, Both ends pivotally connected to said connecting nest and corresponding said main support respectively; Wherein the spring and the connecting member are both fitted to the supporting column, the connecting member is located below the spring, and the corresponding end of the main support is pivotally connected to the connecting member, In this case,

The connecting member includes an inner section, an intermediate section and an outer section, the through-holes communicating with the supporting columns along the radial direction, and the through-holes having a diameter gradually increased, wherein the receiving chamber is formed in the middle section of the through- Wherein a small spring is fitted in a section of the insertion pin corresponding to the accommodating chamber, the outer end of the insertion pin is connected to an operation section, and the lower end of the support column The insertion pin hole for inserting the insertion pin head of the insertion pin is formed to correspond to the inner section of the through hole and a flange abutting the end of the small spring is provided on the surface of the inner end of the insertion pin in a ring shape , And a stopper for blocking a corresponding end of the small spring is accommodated in an outer section of the through hole The.

And a contact support block is provided at a position corresponding to the insertion pin hole in the support column.

The operation portion and the insertion pin are integrally structured, and a pulling auxiliary hole is formed on the surface of the operation portion.

Since the upper frame of the folding type tent according to the present invention using the above-described structure is designed to fold the folding type tent by pulling the insertion pin outward, the structure is simple and it is not necessary to be hard when folded. When the tent is to be folded, the tent can be folded upward by releasing the position fixing between the connecting member and the supporting column by holding the operating portion with the hand and pulling it out to disengage the insertion pin head from the insertion pin hole. Since the flange on the insert pin surface abuts the small spring, the small spring is deformed in the process of moving the insert pin outwards, so that the small spring is in a compressed state; When the tent needs to be unfolded again, the connecting member is moved downward along the support column to the insertion pin hole, so that a small spring, which is in a state of compression all the time, tends to restore its natural elastic state, The insertion pin head is inserted into the insertion pinhole so that the fixing of the position between the connecting member and the supporting column is implemented again.

Furthermore, at a position corresponding to the insertion pin hole in the support column, a contact support block is provided so that the insertion pin head abuts against the contact support block. When the compressive strain of the small spring is too large, the flange of the insert pin surface does not easily collide with the inner wall of the receiving chamber because the contact support block can partially buffer the elastic deformation during instantaneous restoration, The ability to fold the tent in order to prevent it can be retained for a long time.

Furthermore, the pull-down auxiliary holes formed in the operating portion can be conveniently folded by providing a point at which the user applies a force when pushing the fingers in and out of the insertion pin.
