[0002] A retractable gate is a gate device that can automatically retract. It typically consists of a roll tube, a mesh, a drive mechanism, and a locking mechanism. Its main function is to wind the gate material, such as telescopic fabric, onto the roll tube and automatically retract and lock it through the drive mechanism, thereby conveniently controlling the opening and closing of the gate.
[0003] When controlling the entrance to a building, retractable gates are needed to block vehicles or people. Traditional retractable gates are usually fixed with hooks when unfolded. The structure is simple, but the hooks are very easy to fall off when shaken by external forces, so they need to be re-fixed. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a retractable gate that has the advantage of being fixed and stable. It solves the problem that traditional retractable gates, when unfolded, usually use a hook structure for hooking and fixing. The structure is simple, but the hook is very easy to fall off when shaken by external force, thus requiring re-fixing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable door frame, comprising a door frame body, a through-hole block fixedly connected to the bottom right position of the door frame body, an L-shaped rod slidably connected to the inner wall of the through-hole block, a cylindrical hole structure opened on the right side of the L-shaped rod, a pressing block slidably connected to the inner wall of the cylindrical hole structure of the L-shaped rod, a locking block provided at the front and rear positions on the left side of the pressing block, the outer side of the locking block extending through to the surface of the L-shaped rod, a V-shaped elastic rod fixedly connected to the inner side of the locking block, and a limiting groove for cooperating with the V-shaped elastic rod opened at the middle position on the left side of the inner wall of the L-shaped rod;
[0006] The pressing block has a V-shaped hole structure on its left side, the card block is L-shaped, the side of the card block facing the pressing block has a chamfer structure that works with the tapered hole structure, and the right side of the card block has a chamfer structure that works with the through hole block.
[0007] As a preferred embodiment of this utility model, the bottom of the L-shaped rod is fixedly connected to a base, and the base is elliptical in shape.
[0008] As a preferred embodiment of this utility model, the inner wall of the L-shaped rod is provided with sliding grooves at the upper and lower positions on the left side, and the left side of the pressing block is fixedly connected with a slider that cooperates with the sliding grooves.
[0009] As a preferred embodiment of this utility model, the slider is J-shaped, and a limiting block that cooperates with the slider is fixedly connected to the inner wall of the groove.
[0010] As a preferred embodiment of this utility model, a pull ring is fixedly connected to the lower right side of the gate body.
[0011] As a preferred embodiment of this utility model, a lifting hole is provided at the lower front side of the gate body.
[0012] As a preferred embodiment of this invention, the V-shaped elastic rod is made of stainless steel.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. In this utility model, the through-hole block is first placed on the L-shaped rod. As the through-hole block continues to move, it is pressed inward by the chamfered structure of the locking block. When the through-hole block moves to the bend of the L-shaped rod and disengages from the locking block, the locking block is reset by using the V-shaped elastic rod. At this time, the locking block can be used to limit the through-hole block and prevent it from disengaging from the L-shaped rod, thereby achieving a fixed and stable effect.
[0015] 2. This utility model provides support for the L-shaped rod by setting a base, which makes it more convenient for users. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4 As shown, the present invention provides a retractable door frame, including a door frame body 1. A through hole block 2 is fixedly connected to the bottom right position of the door frame body 1. An L-shaped rod 3 is slidably connected to the inner wall of the through hole block 2. A cylindrical hole structure is opened on the right side of the L-shaped rod 3. A pressing block 4 is slidably connected to the inner wall of the cylindrical hole structure of the L-shaped rod 3. A locking block 5 is provided at the front and rear positions on the left side of the pressing block 4. The outer side of the locking block 5 extends through to the surface of the L-shaped rod 3. A V-shaped elastic rod 6 is fixedly connected to the inner side of the locking block 5. A limiting groove 7 is opened at the middle position on the left side of the inner wall of the L-shaped rod 3 to cooperate with the V-shaped elastic rod 6.
[0024] The left side of the pressing block 4 has a V-shaped hole structure, and the shape of the locking block 5 is L-shaped. The side of the locking block 5 facing the pressing block 4 has a chamfer structure that works with the conical hole structure. The right side of the locking block 5 has a chamfer structure that works with the through hole block 2. The retractable door frame can be adjusted in orientation according to usage requirements, and the adjustment will not affect its normal use.
[0025] refer to Figure 2 The bottom of the L-shaped rod 3 is fixedly connected to a base 8, which is elliptical in shape.
[0026] As a technical optimization of this utility model, by setting the base 8, the L-shaped rod 3 can be supported, which makes it more convenient for users to use.
[0027] refer to Figure 3 The inner wall of the L-shaped rod 3 has grooves 9 on the upper and lower left sides, and a slider 10 that works with the grooves 9 is fixedly connected to the left side of the pressing block 4.
[0028] As a technical optimization of this utility model, by setting the sliding groove 9 and the slider 10, the pressing block 4 can be limited to prevent it from shaking during use.
[0029] refer to Figure 3 The slider 10 is J-shaped, and the inner wall of the groove 9 is fixedly connected to a limiting block 11 that works with the slider 10.
[0030] As a technical optimization of this utility model, by setting a limiting block 11, the range of motion of the slider 10 and the pressing block 4 can be limited, preventing the slider 10 and the pressing block 4 from detaching from the L-shaped rod 3.
[0031] refer to Figure 2 A pull ring 12 is fixedly connected to the lower right side of the gate body 1.
[0032] As a technical optimization of this utility model, by setting the pull ring 12, the contact area between the user's hands and the through-hole block 2 can be increased, making it easier for the user to move the through-hole block 2.
[0033] refer to Figure 1 A lifting hole 13 is provided on the lower front side of the gate body 1.
[0034] As a technical optimization of this utility model, by setting the lifting hole 13, the user can hold the bottom of the door frame body 1 with both hands, which facilitates the user's movement of the door frame body 1.
[0035] refer to Figure 4 The V-shaped elastic rod 6 is made of stainless steel.
[0036] As a technical optimization of this utility model, by setting a V-shaped elastic rod 6 made of stainless steel, it is possible to prevent the V-shaped elastic rod 6 from rusting and to prevent the V-shaped elastic rod 6 from being damaged due to rusting.
[0037] The working principle and usage process of this utility model are as follows: In use, firstly, pull the gate body 1 through the lifting hole 13 so that the through hole block 2 is located on the right side of the L-shaped rod 3. Then, move the through hole block 2 to the left so that the through hole block 2 fits onto the L-shaped rod 3. Continue to move the through hole block 2. The through hole block 2 is pressed inward by the chamfered structure of the locking block 5. The locking block 5 is pressed inward by the V-shaped elastic rod 6 to retract it. When the through hole block 2 moves to the bend of the L-shaped rod 3 and disengages from the locking block 5, the V-shaped elastic rod 6 rebounds and generates elastic force to drive the locking block 5 to move outward, so that the locking block 5 is reset. At this time, the locking block 5 can be used to limit the through hole block 2 to prevent the through hole block 2 from disengaging from the L-shaped rod 3, thereby achieving a fixed and stable effect. When separation is required, press the pressing block 4. Use the V-shaped hole structure on the pressing block 4 to press the locking block 5 inward, so that the locking block 5 moves inward and retracts into the L-shaped rod 3. At this time, moving the through hole block 2 to the right will separate it from the L-shaped rod 3.
[0038] In summary, this retractable door frame, by incorporating the door frame body 1, through-hole block 2, L-shaped rod 3, pressing block 4, locking block 5, V-shaped elastic rod 6, and limiting groove 7, solves the problem that traditional retractable door frames, which typically use hook structures for fixing when unfolded, have simple structures but are prone to detaching when subjected to external forces, requiring re-fixing.
