Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically to a pusher rotation structure. Background Technology

[0002] In the field of generator technology, the generator frame, as the core support structure, is crucial for ensuring the stability of the generator during transportation, use, and storage. The push handle, a key component of the frame, primarily functions to provide a point of leverage, allowing operators to easily move the typically heavy generator to meet usage needs in various scenarios. Therefore, the push handle structure needs a reliable locking function to maintain a fixed position while the generator is operating, and its rotation and retraction functions should balance ease of operation with safety.

[0003] Chinese patent document CN217583710U discloses a generator frame, including a frame body and a pusher hinged to the frame body; wherein: the pusher is connected to the frame body through a locking structure, the locking structure includes a support rod and a limiting rod, a movable groove is provided at the end of the pusher away from the frame body, one end of the support rod is hinged to the frame body, and the other end is located in the movable groove; the limiting rod is located on the pusher and can restrict the support rod from sliding in the movable groove.

[0004] The existing technology uses a support rod and a limit rod to support and lock the pusher. However, due to the large clearance between the support rod and the movable groove, the locking structure is prone to loosening, causing the pusher to wobble under force and indicating insufficient structural strength. Furthermore, during the rotation or locking process of the pusher, the support rod and limit rod can easily pinch the operator's fingers or clothing, posing a safety hazard. Additionally, this structure is prone to wear after long-term use, further reducing locking reliability and affecting the overall user experience of the generator. Utility Model Content

[0005] To solve the aforementioned technical problems, this utility model provides a pusher rotation structure, including a pusher, characterized in that it further includes a rotating arm, a mounting base, a rotating shaft, and a returnable pin. The pusher is connected to the rotating arm, and the rotating arm is connected to the mounting base via the rotating shaft. The mounting base is provided with a limiting baffle for limiting the upward position of the rotating arm and at least one limiting hole arranged along the circumferential direction of the center of the rotating shaft. The pin is elastically connected to the rotating arm and is used to connect or separate from the limiting hole.

[0006] Preferably, the mounting base is provided with a limiting hole one and a limiting hole two. The rotating arm has a raised position and a folded position relative to the mounting base. When the rotating arm is in the raised position, the pin is in the limiting hole one under the action of elastic force, and when the rotating arm is in the folded position, the pin is in the limiting hole two under the action of elastic force.

[0007] To facilitate lifting and reduce lifting resistance, the second limiting hole is a blind hole or a shallow pit.

[0008] Preferably, the first limiting hole and the second limiting hole are located in the axial direction of the rotating shaft and are directly opposite the rotating arm.

[0009] To facilitate folding and lifting and improve safety, a guide groove is provided between the first limiting hole and the second limiting hole in the circumferential direction of the center of the rotating shaft. The depth of the guide groove increases from the first limiting hole to the second limiting hole.

[0010] To facilitate quick folding and lifting, the rotating arm is provided with a limiting baffle three. When the rotating arm is in the raised position, the pin is in the limiting hole one under the action of elastic force, and the limiting baffle three is in contact with the limiting baffle one.

[0011] To facilitate limiting the movement of the rotating arm, a second limiting baffle is provided on the mounting base, and the second limiting baffle is arranged in the arc direction of the center of the rotating shaft.

[0012] To facilitate control of the pin, a handle is fixedly connected to the end of the pin away from the mounting base, and a compression spring is fitted between the pin and the rotating arm.

[0013] To create resistance between the swing arm and the mounting base, preventing it from falling off rapidly after the push handle is released and causing an accident, the swing shaft is a stepped bolt, and a nylon washer and an elastic washer are fitted on the stepped bolt; on the swing shaft, the nylon washer is located between the swing arm and the mounting base, separating the two; the elastic washer is located on the side of the swing arm away from the mounting base, and is assembled to the swing arm by the stepped bolt.

[0014] To facilitate shock absorption and improve the stability of the pusher, the limiting baffle three is provided with shock-absorbing rubber, which is compressed when it is in the raised position.

[0015] This utility model has the following beneficial effects: 1. This utility model uses a pin and a limiting hole for positioning, and multiple limiting baffles fit together to limit the force between the maximum stroke. The pin and the limiting hole determine the two positions of the pusher: raised and folded. Specifically, when the pin falls into the second limiting hole, the pusher is in the folded state. When the pusher and the rotating arm rotate clockwise, and the first and third limiting baffles come into contact, the pin falls into the first limiting hole, placing the pusher in the raised position. During the adjustment from the folded to the raised position, the pin pushes past the second limiting hole, making it relatively easy to raise the pusher. When the pusher reaches the raised position, the pin falls into the first limiting hole, automatically locking it. If the pusher needs to be folded, the handle must be pulled out to disengage the pin from the limiting hole. Furthermore, the overall structure of this utility model has no exposed parts, and the integrated structure of the mounting base and rotating arm ensures the safety, stability, and robustness of the pusher during use.

[0016] 2. The nylon washers and spring washers fitted on the rotating shaft are designed to create resistance between the rotating arm and the mounting base after the stepped bolts are tightened, preventing the push handle from falling off rapidly after release and causing an accident. The friction between the rotating shaft and the rotating arm can be adjusted using the nylon washers and spring washers. When the friction is greater, the rotating arm and push handle will not fall off even after the pin separates from the limit pin hole; when the friction is less, the rotating arm and push handle will fall off slowly, thus further ensuring safety during use.

[0018] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings of the instruction manual include: push handle 1, rotating arm 2, mounting base 3, rotating shaft 4, pin shaft 5, limit baffle one 6, limit hole one 7, limit hole two 8, guide groove 9, limit baffle two 10, limit baffle three 11, handle 12, compression spring 13, nylon gasket 14, elastic gasket 15, shock-absorbing rubber 16, generator frame 17, flat gasket 18, limit baffle four 19.

[0019] Example 1 like Figure 1-7 As shown, a pusher rotation structure includes a pusher 1, a rotating arm 2, a mounting base 3, a rotating shaft 4, and a returnable pin 5. The pusher 1 has rotating arms 2 connected to both ends. The rotating arms 2 are connected to the mounting base 3 via the rotating shaft 4, and the rotating arms 2 enclose the mounting base 3 within it. The mounting base 3 is fixed to a generator frame 17. The mounting base 3 is provided with a limiting baffle 6 for limiting the upward position of the rotating arm 2, and at least one limiting hole arranged along the circumferential direction of the center of the rotating shaft 4. The pin 5 is elastically connected to the rotating arm 2 via a first limiting hole 7 and a second limiting hole 8. The rotating arm 2 has a raised position and a folded position relative to the mounting base 3. When the rotating arm 2 is in the raised position, the pin 5 is in the first limiting hole 7 under the action of elastic force. When the rotating arm 2 is in the folded position, the pin 5 is in the second limiting hole 8 under the action of elastic force. The number of limiting holes is increased according to the actual required gear position.

[0020] The limiting hole 8 is a blind hole or a shallow pit.

[0021] The limiting hole 7 and the limiting hole 8 are located in the axial direction of the rotating shaft 4 and are directly opposite the rotating arm 2.

[0022] A guide groove 9 is arranged circumferentially between the first limiting hole 7 and the second limiting hole 8, with the depth of the guide groove 9 increasing from the first limiting hole 7 to the second limiting hole 8. When it is necessary to lift the push handle 1, the pin 5 can automatically and easily disengage from the second limiting hole 8. When the pin 5 engages with the first limiting hole 7, it locks the push handle 1, ensuring its safety during use.

[0023] The rotating arm 2 is provided with a limiting baffle 3 11. When the rotating arm 2 is in the raised position, the pin 5 is in the limiting hole 7 under the action of elastic force, and at the same time, the limiting baffle 3 11 is in contact with the limiting baffle 6.

[0024] The mounting base 3 is provided with a second limiting baffle 10, which is arranged in the arc direction of the center of the rotating shaft 4. The rotating arm 2 is provided with a fourth limiting baffle 19, which contacts and limits the movement of the first limiting baffle 10 and the fourth limiting baffle 19.

[0025] A handle 12 is fixedly connected to the end of the pin 5 away from the mounting base 3. A compression spring 13 is fitted between the pin 5 and the rotating arm 2. Pulling the handle 12 along the axis of the rotating shaft 4 can drive the pin 5 to overcome the action of the compression spring 13 and move away from the mounting base 3. When the handle 12 is released, the pin 5 is in contact with the mounting base 3 under the action of the compression spring 13.

[0026] The rotating shaft 4 is a stepped bolt with a stepped structure in the middle. A nylon washer 14, an elastic washer 15, and a flat washer 18 are fitted onto the stepped bolt. The nylon washer 14 is positioned between the rotating arm 2 and the mounting base 3, separating them. The elastic washer 15 and the flat washer 18 are located on the side of the rotating arm 2 away from the mounting base 3, and are assembled to the rotating arm 2 by the stepped bolt. This creates resistance between the rotating arm 2 and the mounting base 3, preventing the push handle 1 from falling off rapidly and causing an accident.

[0027] The limiting baffle 11 is provided with shock-absorbing rubber 16, which is compressed when it is in the raised position. After the shock-absorbing rubber 16 is compressed, the pin 5 and the pin hole fit more tightly, and the push handle 1 will not shake during use.

[0028] The limiting baffle 6 and the limiting baffle 11 fit together to limit the force between the maximum stroke. The pin 5, along with the limiting holes 7 and 8, determines the two positions of the pusher 1: raised and folded. When the pin 5 is in the limiting hole 8, the pusher 1 is in the folded state. When the pusher 1 and the rotating arm 2 rotate clockwise, and the limiting baffle 6 and the limiting baffle 11 come into contact, the pin 5 falls into the limiting hole 7, placing the pusher 1 in the raised position. During the adjustment of the pusher 1 from the folded position to the raised position, the pin 5 pushes past the limiting hole 8, making it relatively easy to raise the pusher 1. When the pusher 1 reaches the raised position, the pin 5 automatically locks itself because it is in the limiting hole 7. If the pusher 1 needs to be folded, the handle 12 needs to be pulled out to disengage the pin 5 from the limiting hole.
