Description

Technical Field

[0001] This utility model relates to the field of folding brackets, and in particular to a folding bracket for a small hand-cranked generator. Background Technology

[0002] Hand-cranked generators can provide power to small and medium-sized electrical devices, supporting tasks such as lighting, communication, and data recording. They can also be used in areas without power grids, providing essential power support to workers and playing a significant role in field operations and emergency rescue. For portability, hand-cranked generators are designed to be relatively small, requiring a support frame for hand-cranking.

[0003] Therefore, it is essential to develop a hand-cranked generator support frame that is compact and easy to carry when traveling. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model proposes a folding bracket for a small hand-cranked generator. The advantages of this utility model are its small size, foldability, and ease of portability.

[0005] To achieve the above objectives, a folding bracket for a small hand-cranked generator is proposed, comprising a generator mounting plate that folds upwards and in the center, and a support leg. A connecting rod is hinged to each end of the generator mounting plate, and the other end of the connecting rod is hinged to the upper part of the support leg. A gap is left between the hinge point of the connecting rod and the top of the support leg. A generator limiting groove is provided at one end of the generator mounting plate, which engages with a limiting plate at the rear end of the hand-cranked generator for positioning. A locking device is provided at the other end of the generator mounting plate, comprising a fixing seat and a long pin. The fixing seat has a through hole. When installing the hand-cranked generator, the long pin passes sequentially through the fixing seat and the mounting block at the front end of the hand-cranked generator to fix and limit its position.

[0006] Based on the above, the beneficial effects of a folding bracket for a small hand-cranked generator are as follows: it solves the problem of the large size and inconvenience of carrying hand-cranked generators. In this utility model, the generator mounting plate has an upward and centered folding structure. The generator mounting plate and the support legs are connected by the connecting rod. When carried in the field, the generator mounting plate is folded in the center, and the support legs are folded together by the connecting rod, ultimately achieving folding and reducing the space occupied by the hand-cranked generator, making it more convenient to carry. When using the folding bracket, the limiting groove cooperates with the locking device to fix and limit the hand-cranked generator, preventing it from moving during hand-cranking and making the folding bracket more stable during use.

[0007] Furthermore, the generator mounting plate includes a generator mounting plate one and a generator mounting plate two, which are hinged together by a pivot shaft one.

[0008] Based on the above, the generator mounting plate is split into generator mounting plate one and generator mounting plate two, and is hinged together by a pivot shaft one to facilitate the folding of the folding bracket.

[0009] Furthermore, a second pivot and a third pivot are respectively provided at the hinge joints at both ends of the connecting rod.

[0010] Based on the above, the hinges of the second and third pivots make the rotation at the hinge point more stable and smooth.

[0011] Furthermore, two connecting rods are respectively hinged to the two sides of the middle of the support frame via a pivot four, and the other end of the connecting rods is hinged to the pivot one.

[0012] Based on the above, the second connecting rod is hinged to the support leg and the first rotating shaft respectively, so that the generator mounting plate, the support leg and the second connecting rod form a stable triangular force-bearing structure, which improves the stability of the support.

[0013] Furthermore, the upper part of the support frame is also provided with a handle groove, the edges of which are rounded.

[0014] Based on the above, when the bracket is folded, it can be held by the handle slot, making it more convenient to carry.

[0015] Furthermore, the front end of the mounting plate is provided with a clearance groove.

[0016] Based on the above, the clearance groove allows the hand-cranked generator to avoid interference with the generator mounting plate during installation.

[0017] Furthermore, the lower part of the support frame is provided with a hollow area.

[0018] Based on the above, the hollowed-out area can reduce the weight of the bracket and facilitate folding.

[0019] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0026] like Figures 1 to 5 As shown, it includes an upwardly folding generator mounting plate 1 and a support bracket 2. Both ends of the generator mounting plate 1 are hinged to connecting rods 3, and the other end of each connecting rod is hinged to the upper part of the support bracket 2. A gap exists between the hinge point of the connecting rod 3 and the top of the support bracket 2. When the folding bracket is unfolded, the top of the support bracket 2 supports the generator mounting plate 1. One end of the generator mounting plate 1 is provided with a generator limiting groove 4, which engages with a limiting plate 6 at the rear end of the hand-cranked generator 5 for positioning. The other end of the generator mounting plate 1 is provided with a locking device 7, which includes a fixing base 8 and a long pin 9. The fixing base 8 has a through hole 10. When installing the hand-cranked generator 5, the long pin 9 passes sequentially through the fixing base 8 and the mounting block 11 at the front end of the hand-cranked generator 5 to fix and limit its movement. The front end of the generator mounting plate 1 is also provided with a clearance groove 20, which corresponds to the mounting block 11 to avoid interference between the mounting block 11 and the generator mounting plate 1.

[0027] Preferably, the generator mounting plate 1 includes a first generator mounting plate 12 and a second generator mounting plate 13, which are hinged together by a first rotating shaft 14. Meanwhile, the hinge points at both ends of the connecting rod 3 are respectively provided with a second rotating shaft 15 and a third rotating shaft 16.

[0028] Preferably, the two sides of the middle of the support leg 2 are respectively hinged to the connecting rod 18 via the pivot 17, and the other end of the connecting rod 18 is hinged to the pivot 14. The lower part of the support leg 2 is also provided with a hollow area 21, which reduces the overall structure and facilitates the folding of the support.

[0029] like Figure 2 The diagram shows the structure of the support frame after folding. When carried outdoors, the generator mounting plate 12 and generator mounting plate 2 13 can be folded together via pivot 14, and the connecting rod 3 can be rotated around pivot 2 15 towards both sides of the generator mounting plate 1. At this time, the support leg 2 folds inward around pivot 3 16 and moves towards generator mounting plate 12 and generator mounting plate 2 13 respectively, ultimately achieving folding and reducing the space occupied by the hand-cranked generator 5, making it more convenient to carry. The connecting rod 2 18 is hinged to the support leg 2 and pivot 14, forming a stable triangular force-bearing structure with the generator mounting plate 1, the support leg 2, and the connecting rod 2 18, improving the stability of the support frame. Furthermore, the upper part of the support leg 2 is provided with a handle groove 19, the edges of which are rounded. When the support frame is folded, it can be held by the handle groove 19 for easy carrying.

[0030] like Figure 3 and Figure 4 The diagram shown is a simplified diagram of the mechanism of this utility model in two states. Through the simplified diagram, the implementation principle of this utility model can be understood more intuitively.

[0031] The specific implementation of this embodiment is as follows: When using the bracket to support the hand-cranked generator 5, the limiting plate 6 is inserted into the limiting groove, and then the long pin 9 is passed through the fixed base 8 and the mounting block 11 for fixed positioning. The bracket allows the hand-cranked generator 5 to be adjusted to a certain height for convenient use. When carried in the field, the generator mounting plate 12 and the generator mounting plate 13 can be folded together by the pivot 14, and the connecting rod 3 can be rotated around the pivot 15 to both sides of the generator mounting plate 1. At this time, the support leg 2 folds inward around the pivot 16 and moves closer to the generator mounting plate 12 and the generator mounting plate 13, thus achieving folding, reducing the space occupied by the hand-cranked generator 5, and making it more convenient to carry when going out.

[0032] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
