Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a combined bracket that is easy to connect. Background Technology

[0002] Modular supports are support structures that can be flexibly assembled, adjusted, and configured according to needs. They are widely used in various industrial, mechanical, electrical, and construction fields. Modular supports have high adaptability. For example, they can be used for temporary support and scaffolding systems in building construction to meet the needs of different construction stages. In mechanical equipment, modular supports can be used to support equipment parts, components, or systems, providing a stable and fixed foundation.

[0003] The ease of use and safety of the connection method for connecting brackets directly affect construction efficiency and operator safety. Existing connecting brackets mostly use bolt connections, mortise and tenon connections, and spring pin connections. Bolt connections are inconvenient to operate and inefficient, and there is a risk of tools falling when working at heights or in confined spaces. Mortise and tenon connections have the advantage of structural stability, but they require strict precision in the machining of the tenon and mortise. Spring pin connections have the characteristic of quick installation, but the spring force during insertion can easily cause hand pinching accidents.

[0004] To address the aforementioned issues, we propose a modular support structure that facilitates easy connection. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing a combination bracket that is easy to connect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular support that is easy to connect, comprising a first support and a second support. The outer wall of the first support is rotatably connected to a support rod one via a connector, and the outer wall of the second support is rotatably connected to a support rod two via a connector. The end of the support rod one is provided with a slot, and the outer wall of the slot is rotatably connected to a clamping plate via a torsion spring shaft. An electric push rod is provided on the rear side of the clamping plate, and the telescopic end of the electric push rod is fixedly connected to a push plate that pushes the clamping plate to rotate. The end of the support rod two is provided with a tenon, and a limiting component is provided between the clamping plate and the support rod two.

[0007] In the aforementioned easy-to-connect combination bracket, a sliding plate is slidably disposed within the slot, and a pop-out spring is fixedly connected between the sliding plate and the inner wall of the slot.

[0008] In the aforementioned easy-to-connect combination bracket, the limiting component includes a limiting buckle fixed on the outer wall of the clamping plate, and the outer wall of the second support rod has a hole that matches the limiting buckle.

[0009] In the aforementioned easy-to-connect combination bracket, the first bracket is provided with a time delay protection module connected to the electric push rod.

[0010] In the aforementioned easy-to-connect combination bracket, the connector includes a U-shaped seat fixed on support rod one and support rod two, a rotating shaft passing through the U-shaped seat, and limit plates fixedly connected to both ends of the rotating shaft. The ends of support rod one and support rod two are fixedly connected to the outer wall of the rotating shaft. A rotating hole is provided at the connection between the U-shaped seat and the rotating shaft, and the gap between the rotating hole and the outer wall of the rotating shaft is less than 0.1 mm.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] 1. When connecting the first bracket and the second bracket, align the tenon with the slot, and push the first bracket and the second bracket towards the middle at the same time so that the tenon is fully inserted into the slot. Then start the electric push rod. The drive end of the electric push rod drives the push plate to move forward. The push plate contacts the outer wall of the clamp plate and pushes the four clamp plates to rotate inward together until the clamp plates rotate and stick to the outer surface of the second support rod, thus completing the initial connection and fixation of the first bracket and the second bracket.

[0013] 2. After the clamp plate rotates to be close to the surface of the second support rod, the end of the limit buckle is inserted into the hole to realize the secondary connection and fixation between the clamp plate and the second support rod, preventing the clamp plate from detaching from the second support rod and ensuring the stability of the connection between the first bracket and the second bracket.

[0014] In summary, this utility model, by setting a rotatable clamping plate, allows the clamping plate to rotate and contact the second support rod after the tenon is inserted into the slot. The clamping plate is then pushed to rotate by an electric push rod and pressed against the second support rod. The limiting buckle is then inserted into the hole to complete the connection and clamping of the clamping plate and the second support rod, thus completing the connection of the first bracket and the second bracket. The connection is convenient and quick, and avoids the occurrence of hand pinching accidents. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A modular support bracket for easy connection includes a first bracket 1 and a second bracket 2. The outer wall of the first bracket 1 is rotatably connected to a support rod 3 via a connector. The outer wall of the second bracket 2 is rotatably connected to a support rod 4 via a connector. A slot is provided at the end of the support rod 3. A clamping plate 6 is rotatably connected to the outer wall of the slot via a torsion spring shaft 5. In its original state, the clamping plate 6 is in an outwardly rotatable position. An electric push rod 7 is located on the rear side of the clamping plate 6. A time-delay protection module connected to the electric push rod 7 is provided on the first bracket 1. The time-delay protection module is a protective device used in electrical systems, mainly used to delay the triggering of certain protective actions to prevent unnecessary shutdowns or actions caused by momentary or brief faults. It is commonly used in applications requiring a delay before execution. In protective operations, especially in power systems, automation control, and mechanical equipment, its function is to ensure the stable operation of the system in a short period of time and avoid malfunctions. The telescopic end of the electric push rod 7 is fixedly connected to the push plate 8 that pushes the clamping plate 6 to rotate. The end of the support rod 2 4 is provided with a tenon 9. When connecting the first bracket 1 and the second bracket 2, after aligning the tenon 9 with the slot, push the first bracket 1 and the second bracket 2 towards the middle at the same time so that the tenon 9 is fully inserted into the slot. Then start the electric push rod 7. The drive end of the electric push rod 7 drives the push plate 8 to move forward. The push plate 8 contacts the outer wall of the clamping plate 6 and pushes the four clamping plates 6 to rotate inward together until the clamping plates 6 rotate and stick to the outer surface of the support rod 2 4, completing the initial connection and fixation of the first bracket 1 and the second bracket 2.

[0021] A limiting component is provided between the clamping plate 6 and the second support rod 4. The limiting component includes a limiting buckle 12 fixed on the outer wall of the clamping plate 6. The outer wall of the second support rod 4 has a hole 13 that matches the limiting buckle 12. The limiting buckle 12 is inserted into the hole 13. After the clamping plate 6 is rotated to be close to the surface of the second support rod 4, the end of the limiting buckle 12 is inserted into the hole 13, realizing the secondary connection and fixation between the clamping plate 6 and the second support rod 4, preventing the clamping plate 6 from detaching from the second support rod 4, and ensuring the stability of the connection between the first bracket 1 and the second bracket 2.

[0022] A sliding plate 10 is slidably installed in the slot. A pop-out spring 11 is fixedly connected between the sliding plate 10 and the inner wall of the slot. When the tenon 9 is inserted into the slot, it will push the sliding plate 10 to move into the slot and squeeze the pop-out spring 11 to retract. When the first bracket 1 and the second bracket 2 are disassembled, the drive end of the electric push rod 7 retracts. Under the elastic force of the torsion spring shaft 5, the clamp 6 rotates outward and opens. The limit buckle 12 disengages from the hole 13. Under the elastic force of the pop-out spring 11, the tenon 9 is popped outward, so that the first bracket 1 and the second bracket 2 are separated, thus completing the disassembly of the first bracket 1 and the second bracket 2.

[0023] The connector includes a U-shaped seat 14 fixed on support rod 3 and support rod 4. A rotating shaft 15 passes through the U-shaped seat 14. Limiting plates are fixedly connected to both ends of the rotating shaft 15. The limiting plates restrict the left and right movement of the rotating shaft 15, preventing the rotating shaft 15 from detaching from the U-shaped seat 14. The ends of support rod 3 and support rod 4 are fixedly connected to the outer wall of the rotating shaft 15. A rotating hole is provided at the connection between the U-shaped seat 14 and the rotating shaft 15. The gap between the rotating hole and the outer wall of the rotating shaft 15 is less than 0.1 mm. The small gap prevents the rotating shaft 15 from shaking, making the rotation of the rotating shaft 15 more stable.

[0024] 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.
