Description

Technical Field

[0001] This utility model belongs to the field of iron frame reinforcement technology, specifically relating to a foldable iron frame rapid reinforcement device. Background Technology

[0002] Folding metal racks, due to their convenient storage and small footprint, have been widely used in daily life and industrial production, such as household folding clothes racks, folding shelves for warehousing and logistics, temporary support folding racks for construction, and portable folding storage racks for outdoor camping. The core folding structure of existing folding metal racks typically relies on hinges and other articulated components to achieve the rotation and folding of adjacent metal rods to meet storage needs when not in use. However, when unfolded, additional reinforcement structures are needed to position and fix the unfolded metal rods to ensure the rack's load-bearing stability.

[0003] The existing methods for reinforcing folding iron frames mostly use bolt connections. The connection and reinforcement require the use of tools such as screwdrivers to screw the bolts into the corresponding bolt holes one by one, which is relatively troublesome and not convenient. Utility Model Content

[0004] The purpose of this invention is to provide a foldable iron frame quick reinforcement device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable iron frame quick reinforcement device, comprising a first iron rod, a second iron rod, and a reinforcement mechanism, wherein the second iron rod is hinged to one end of the first iron rod, and the reinforcement mechanism comprises reinforcement rods hinged to both sides of the first iron rod and a positioning component fixedly connected to one end of the reinforcement rod; The positioning component includes a sleeve fixedly connected to one end of the reinforcing rod, a spring disposed inside the sleeve, and a positioning post abutting against one end of the spring. A pull rod is fixedly connected to the end of the positioning post near the spring, and positioning grooves adapted to the positioning post are provided on both sides of the second iron rod.

[0006] In a preferred embodiment, a hinge is provided between the first iron rod and the second iron rod, and the first iron rod and the second iron rod are hinged to each other by the hinge.

[0007] In a preferred embodiment, both sides of the first iron rod are fixedly connected to a rotating shaft, and one end of the reinforcing rod is rotatably sleeved on the rotating shaft.

[0008] In a preferred embodiment, a limiting ring is provided on the inner wall of the sleeve, and an annular groove is provided on the outer wall of the positioning post, with the limiting ring sliding within the annular groove.

[0009] In a preferred embodiment, the spring is sleeved on the pull rod, and one end of the pull rod slides through to the end of the sleeve away from the positioning post.

[0010] In a preferred embodiment, both sides of the first iron rod are provided with receiving grooves that are compatible with the positioning post.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This foldable iron frame quick reinforcement device, through the setting of the reinforcement mechanism, when it is necessary to connect and reinforce the first and second iron rods after they are unfolded, can be used by holding the reinforcement rod and rotating it around the pivot while pulling the pull rod, so that the pull rod drives the positioning column to retract into the sleeve. At this time, the spring will be in a compressed state. Then, rotate the reinforcement rod so that the sleeve is aligned with the positioning groove on the second iron rod. Finally, release the pull rod, so that the spring pushes the positioning column into the positioning groove, so that the reinforcement rod is fixed between the first and second iron rods to form a triangular stable structure, thereby quickly reinforcing the iron frame. The operation is very convenient. This foldable iron frame quick reinforcement device, through the setting of the receiving groove, when it is necessary to fold the first iron rod and the second iron rod, simply pull the pull rod to pull the positioning post out of the positioning groove, then rotate the reinforcement rod so that the sleeve is aligned with the receiving groove on the first iron rod, and finally release the pull rod so that the spring pushes the positioning post into the receiving groove, thereby fixing the reinforcement rod on both sides of the first iron rod, so that the iron frame can be folded quickly.

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-3 This utility model provides a foldable iron frame quick reinforcement device, including a first iron rod 1, a second iron rod 2 and a reinforcement mechanism 3. The second iron rod 2 is hinged to one end of the first iron rod 1. A hinge 11 is provided between the first iron rod 1 and the second iron rod 2. The first iron rod 1 and the second iron rod 2 are hinged to each other through the hinge 11. The hinge 11 enables the first iron rod 1 and the second iron rod 2 to rotate and fold.

[0017] The reinforcement mechanism 3 includes reinforcement rods 31 hinged to both sides of the first iron rod 1 and positioning components 32 fixedly connected to one end of the reinforcement rods 31. A rotating shaft 12 is fixedly connected to both sides of the first iron rod 1. One end of the reinforcement rod 31 is rotatably sleeved on the rotating shaft 12. The positioning component 32 includes a sleeve 321 fixedly connected to one end of the reinforcement rod 31, a spring 322 disposed within the sleeve 321, and a positioning post 323 abutting against one end of the spring 322. A pull rod 324 is fixedly connected to the end of the positioning post 323 near the spring 322. The spring 322 is sleeved on the pull rod 324. One end of the pull rod 324 slides through to the end of the sleeve 321 away from the positioning post 323. The second iron rod 2 has openings on both sides corresponding to the positioning post. The positioning groove 21, which is compatible with the 323, is set by the reinforcement mechanism 3. When it is necessary to connect and reinforce the first iron rod 1 and the second iron rod 2 after they are unfolded, the reinforcement rod 31 can be rotated around the rotating shaft 12 while the pull rod 324 is pulled. The pull rod 324 causes the positioning column 323 to retract into the sleeve 321. At this time, the spring 322 will be in a compressed state. Then, the reinforcement rod 31 is rotated so that the sleeve 321 is aligned with the positioning groove 21 on the second iron rod 2. Finally, the pull rod 324 is released so that the spring 322 pushes the positioning column 323 into the positioning groove 21, so that the reinforcement rod 31 is fixed between the first iron rod 1 and the second iron rod 2 to form a triangular stable structure. This allows for quick reinforcement of the iron frame, and the operation is very convenient.

[0018] The sleeve 321 has a limiting ring 325 on its inner side wall and an annular groove 326 on its outer side wall. The limiting ring 325 slides in the annular groove 326. Through the cooperation of the limiting ring 325 and the annular groove 326, the positioning post 323 can be limited, preventing the positioning post 323 from falling out of the sleeve 321.

[0019] The first iron rod 1 has receiving grooves 13 on both sides that are adapted to the positioning post 323. With the setting of the receiving grooves 13, when it is necessary to fold the first iron rod 1 and the second iron rod 2, simply pull the pull rod 324 to pull the positioning post 323 out of the positioning groove 21, then rotate the reinforcing rod 31 so that the sleeve 321 is aligned with the receiving groove 13 on the first iron rod 1, and finally release the pull rod 324 so that the spring 322 pushes the positioning post 323 into the receiving groove 13, thereby fixing the reinforcing rod 31 on both sides of the first iron rod 1, so that the iron frame can be folded quickly.

[0020] The working principle and usage process of this utility model are as follows: First, when it is necessary to connect and reinforce the unfolded first iron rod 1 and second iron rod 2, the reinforcing rod 31 can be held and rotated around the rotating shaft 12, while simultaneously pulling the pull rod 324, causing the pull rod 324 to drive the positioning pin 323 to retract into the sleeve 321. At this time, the spring 322 will be in a compressed state. Then, rotate the reinforcing rod 31 so that the sleeve 321 is aligned with the positioning groove 21 on the second iron rod 2. Finally, release the pull rod 324, causing the spring 322 to push the positioning pin 323 into the positioning groove 21, thus fixing the reinforcing rod 31. A triangular stable structure is formed between the first iron rod 1 and the second iron rod 2, which can quickly reinforce the iron frame. When it is necessary to fold the first iron rod 1 and the second iron rod 2, simply pull the pull rod 324 to pull the positioning post 323 out of the positioning groove 21, then rotate the reinforcing rod 31 so that the sleeve 321 is aligned with the receiving groove 13 on the first iron rod 1, and finally release the pull rod 324 so that the spring 322 pushes the positioning post 323 into the receiving groove 13, which can fix the reinforcing rod 31 on both sides of the first iron rod 1, so that the iron frame can be folded quickly and the operation is very convenient.
