Description

Technical Field

[0001] This utility model relates to a hinge, specifically a self-locking hinge for connecting support rods, belonging to the field of tent accessories. Background Technology

[0002] Awnings are common outdoor facilities used to shield users from wind, rain, and sunlight. They are mostly made of canvas supported by support poles and can be assembled or disassembled at any time for easy setup and relocation. Existing awning support poles are mostly folding or telescopic. In the case of folding support poles, the folding joints are made by riveting or screwing two support poles together, and the connecting parts have multiple interlocking locking structures. When unfolding or folding, the locking positions on the connecting parts need to be manually adjusted in sequence to change the state of the support poles. This type of structure is relatively complex, cumbersome to operate, and prone to damage. Summary of the Invention

[0003] In view of this, the present invention provides a self-locking hinge for connecting support rods, which aims to securely fix folding support rods while facilitating folding and storage.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A support rod connecting self-locking hinge, wherein the support rod is composed of a fixed section and a movable section hinged at their ends, the fixed section and the movable section are hinged by at least one connecting self-locking hinge, and the connecting self-locking hinge includes a movable part and a positioning part respectively fixedly connected to the fixed section and the movable section;

[0006] The positioning component has a sliding groove, and a fixed rod is located inside the sliding groove. The fixed rod is movably abutted against one end of the sliding groove by a tension spring. The movable component is rotatably connected to one side of the positioning component, and a slot is provided on the movable component to cooperate with the fixed rod.

[0007] Based on the above technical solution, the present invention can be further improved as follows:

[0008] Furthermore, there are at least two tension springs, symmetrically arranged along the length of the fixing rod.

[0009] Furthermore, the fixed section and / or the movable section are composed of two support rods and a connecting rod connected as a whole. The two support rods are arranged parallel to each other at both ends of the connecting rod and are respectively perpendicular to the connecting rod.

[0010] Furthermore, the end of the tension spring furthest from the fixed rod is fixedly connected to the connecting rod or to the positioning component.

[0011] The beneficial effects of this utility model are:

[0012] The self-locking hinge structure of the support rod of this utility model has a simple structure. It replaces the cumbersome structure of traditional buckle or bolt fixing with a snap-fit ​​structure, which greatly increases the installation firmness and convenience of the support rod. Moreover, it is convenient and quick to store and operate, saving production and operating costs. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the overall structure of the self-locking hinge connecting the support rod of this utility model;

[0014] Figure 2 This is a schematic diagram of the folded state of the self-locking hinge connecting the support rod of this utility model.

[0015] The attached diagram lists the components represented by each number as follows:

[0016] 1. Fixed section; 2. Moving section; 3. Moving part; 4. Positioning part; 5. Slide groove; 6. Fixed rod; 7. Tension spring; 8. Slot. Detailed Implementation

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] like Figure 1-2 As shown, the support rod is connected to a self-locking hinge. The support rod is composed of a fixed section 1 and a movable section 2, which are hinged at the ends. The fixed section 1 and the movable section 2 are hinged by at least one self-locking hinge. The self-locking hinge includes a movable part 3 and a positioning part 4, which are fixedly connected to the fixed section 1 and the movable section 2, respectively.

[0019] The positioning component 4 has a sliding groove 5, and a fixing rod 6 is provided in the sliding groove 5. The fixing rod 6 is movably abutted against one end of the sliding groove 5 by a tension spring 7. The movable component 3 is rotatably connected to one side of the positioning component 4, and the movable component 3 has a slot 8 that cooperates with the fixing rod 6.

[0020] In another embodiment of this utility model, the number of tension springs 7 is at least two, which are symmetrically arranged along the length direction of the fixing rod 6.

[0021] In another embodiment of this utility model, the fixed section 1 and / or the movable section 2 are integrally connected by two support rods and a connecting rod. The two support rods are arranged parallel to each other at both ends of the connecting rod and are respectively perpendicular to the connecting rod.

[0022] In another embodiment of this utility model, the end of the tension spring 7 away from the fixed rod 6 is fixedly connected to the connecting rod or to the positioning member 4.

[0023] When the support rod is in the folded state, the fixed section 1 and the movable section 2 abut against each other. At this time, the edge of the movable part 3 abuts against the support rod, and the fixed rod 6 is located in the middle of the slide groove 5 or at the end away from the tension spring 7. When the support rod is unfolded, the movable part 3 rotates along the rivet that is rotatably connected to the positioning part 4. After rotating until the ends of the fixed section 1 and the movable section 2 abut against each other, the support rod is fully unfolded. After the support rod is fully unfolded, the fixed rod 6 is locked into the slot 8 by the tension of the tension spring 7, thus fixing it. If it needs to be folded, the movable section 2 can be rotated by moving the fixed rod 6 to disengage it from the slot 8.

[0024] To ensure the stability of the fixed section 1 and the movable section 2 after they are unfolded, the connecting rods of the two sections are made of square tubes to increase the contact surface and prevent them from bending in the opposite direction due to excessive force.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
