Description

Technical Field

[0001] The utility model belongs to the field of metal profiles, and in particular relates to a retractable and fixed profile matching piece. Background Art

[0002] Traditional profile brackets are mostly designed with fixed lengths. Once production is completed, the size cannot be changed, resulting in limited usage scenarios. With the popularization of the concept of Industry 4.0 and technological advancement, the market demand for products with higher flexibility and stronger adaptability is growing. Although there are some profile bracket products with adjustable sizes on the market.

[0003] Existing adjustable-size profile matching brackets mostly use springs to control the limit buckles and limit holes to vertically match the profiles to limit the connection, which can complete the elongation adjustment and connection fixation. However, when the profile bracket needs to be extended, the limit buckles and springs need to be manually pressed continuously and then the extension operation is performed. The extension operation is time-consuming and the adjustment efficiency is low. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the spring controls the limit buckle and the limit hole to cooperate vertically, so that the manual pressing to extend the position is relatively time-consuming.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: the retractable fixed profile fitting proposed by the present invention includes a support rod and a connecting rod, the lower portion of the support rod is fixed with a base, the support rod and the inner side of the connecting rod are slidably engaged and connected, and also includes a limit mechanism, the side of the limit mechanism is provided with an auxiliary fixing mechanism, the limit mechanism is fixed at the bottom of the connecting rod and the sliding connection of the support rod, the limit mechanism includes a connecting block, a buckle and a limit spring, the connecting block is fixed at the bottom of the connecting rod, a connecting groove is fixed on the connecting block, the buckle and the connecting groove are rotatably connected, one end of the limit spring is connected to the connecting block, and the other end of the limit spring is connected to the buckle, a slide groove is provided on the side of the support rod, a limiting hole is provided inside the slide groove, and the buckle and the limiting hole are movably abutted against each other.

[0006] Furthermore, the bottom end of the buckle and the slide groove are slidably connected.

[0007] Furthermore, the buckle is configured as a bent structure and the angle between it and the connecting block is an acute angle, and the upper portion of the limiting hole is configured as an inclined chamfered structure.

[0008] Furthermore, the buckle is made of high-hardness stainless steel.

[0009] Furthermore, the auxiliary fixing mechanism includes a clamping rod, which is threaded through the connecting block and the side of the connecting rod in sequence. A turntable is fixed on the outside of the clamping rod, and a limiting groove is opened on the side of the support rod. The clamping rod and the limiting groove are movably connected to each other.

[0010] The beneficial effects achieved by the utility model using the above structure are as follows:

[0011] 1. The retractable and fixed profile fitting proposed in this scheme is provided with a limit mechanism at the connection between the connecting rod and the support rod. By pulling the connecting rod, the connecting rod and the support rod can be extended. At the same time, the connecting rod and the support rod can be fixed under the rebound of the limit spring and the limit cooperation of the buckle and the limit hole, and the length adjustment is convenient.

[0012] 2. The retractable and fixed profile fitting proposed in this solution can increase the stability of the connection between the connecting rod and the support rod by providing an auxiliary fixing mechanism on the side of the limiting mechanism for auxiliary clamping and limitation.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, the utility model proposes a retractable fixed profile fitting, including a support rod 1 and a connecting rod 2, a base 101 is fixedly provided at the lower part of the support rod 1, the support rod 1 and the inner side of the connecting rod 2 are slidably engaged and connected, and also include a limiting mechanism 3, an auxiliary fixing mechanism 4 is provided on the side of the limiting mechanism 3, the limiting mechanism 3 is fixedly arranged at the bottom of the connecting rod 2 and the sliding connection of the support rod 1, the limiting mechanism 3 includes a connecting block 301, a buckle 303 and a limiting spring 304, the connecting block 301 is fixedly provided at the bottom of the connecting rod 2, a connecting groove 302 is fixedly provided on the connecting block 301, the buckle 303 and the connecting groove 302 are rotatably connected, one end of the limiting spring 304 is connected to the connecting block 301, and the other end of the limiting spring 304 is connected to the buckle 303, a sliding groove 305 is provided on the side of the support rod 1, and a limiting hole 306 is provided inside the sliding groove 305, and the buckle 303 and the limiting hole 306 are movably opposed to each other.

[0022] like Figure 1-4 As shown, the bottom end of the buckle 303 and the slide groove 305 are slidably connected, the buckle 303 is set to a bent structure and the angle with the connecting block 301 is an acute angle, and the upper part of the limiting hole 306 is set to an inclined chamfer structure, which is convenient for pulling the buckle 303 and the limiting hole 306 out of the chimeric connection when the connecting rod 2 is pulled upward, and under the action of gravity, the buckle 303 and the limiting hole 306 can be connected more tightly. The buckle 303 is made of high-hardness stainless steel, which can prevent rust and bear a higher weight than aluminum.

[0023] like Figure 2-5 As shown, the auxiliary fixing mechanism 4 includes a clamping rod 402, which is threaded through the connecting block 301 and the side of the connecting rod 2 in sequence. A turntable 401 is fixed to the outside of the clamping rod 402, and a limiting groove 403 is opened on the side of the support rod 1. The clamping rod 402 and the limiting groove 403 are movably connected to each other, which is used to strengthen the connection between the fixed connecting rod 2 and the support rod 1 and prevent the buckle 303 and the limiting hole 306 from slipping.

[0024] During specific use, according to the need of support height, the support rod 1 and the base 101 are first erected and fixed, and then the connecting rod 2 is pulled upward. At this time, the slide groove 305 squeezes the buckle 303 outward. Due to the rotation limit of the buckle 303 and the connecting block 301, the buckle 303 squeezes the limit spring 304, and the buckle 303 moves upward with the connecting block 301. When it is extended to the required length, under the action of gravity and the rebound action of the limit spring 304 on the upper part of the buckle 303, the buckle 303 and the limit hole 306 complete the counter-connection, and the length is convenient to adjust. Turn the turntable 401 to tighten the clamping rod 402 and the limit slot 403 to complete the fixation of the connecting rod 2 and the support rod 1, increasing the connection stability.

[0025] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
