Abstract
Description
A handle anti-pinch structure and generator set Technical Field
[0001] This utility model relates to the field of generator set outer frame technology, specifically to a handle anti-pinch structure and a generator set. Background Technology
[0002] Existing generator sets typically have handles on their casings, allowing users to easily move the generator set. To save space and reduce packaging and transportation costs, the handles are usually designed to rotate relative to the casing, making it easy to store them on the panel when not in use.
[0003] Existing handles lack a limiting mechanism to prevent them from returning to their original position. During use, if the handle suddenly falls back onto the control panel, it may trap the user's hand, causing injury. Therefore, an anti-pinch handle structure is proposed. Summary of the Invention
[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a handle anti-pinch structure and generator set to avoid injury to the user's hands and improve safety.
[0005] To achieve the above objectives, this utility model provides a handle anti-pinch structure, including a grip; a first swing arm disposed at one end of the grip, the first swing arm having a first wall surface; a second swing arm disposed at the other end of the grip, the second swing arm facing the first wall surface; a limiting pin telescopically engaged with the first swing arm; and an elastic element for applying elastic force to the limiting pin so that the limiting pin extends beyond the first wall surface.
[0006] Preferably, the first swing arm is provided with a mounting groove, and the limiting pin and the elastic element are both provided in the mounting groove.
[0007] Preferably, the first swing arm is provided with a connecting block, the connecting block covers the outside of the mounting groove, the connecting block is provided with a through hole, and the limiting device extends out of the through hole.
[0008] Preferably, the outer wall of the limiting pin is provided with a limiting flange, which can abut against the side of the connecting block opposite to the second swing arm.
[0009] Preferably, the elastic element is a spring, and its two ends abut against the bottom of the mounting groove and the limiting pin, respectively; the bottom of the mounting groove is provided with a limiting protrusion, and the elastic element is sleeved on the limiting protrusion.
[0010] Preferably, the limiting pin has a recessed relief groove on the side opposite to the second swing arm, and the elastic element extends into the relief groove.
[0011] Preferably, the connecting block is made of metal.
[0012] Preferably, the end of the limiting pin facing the second swing arm has a hemispherical structure.
[0013] This utility model also provides a generator set, including the above-mentioned anti-pinch hand handle structure.
[0014] The beneficial effects of this utility model are:
[0015] This utility model discloses a handle anti-pinch structure and a generator set. By designing a limiting pin on the first swing arm, and utilizing the elastic force applied to the limiting pin by an elastic element, the limiting pin extends beyond the first wall surface after the first swing arm rotates outward. Thus, even if the handle falls back, the limiting pin can still abut against the panel, thereby limiting the return position of the first swing arm and ensuring that the handle, the first swing arm, and the second swing arm do not completely collide with the panel, avoiding injury to the user's hand and improving safety. Simultaneously, when the handle is in the retracted state, the limiting pin, under the action of the elastic element, will continuously press against the second wall surface of the panel, thus preventing outward springing or vibration after the handle is retracted, improving the stability of the handle when retracted.

[0031] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0034] As shown in Figures 1-9, in one embodiment of this utility model, a handle anti-pinch structure is provided, including a grip 10, a first swing arm 20, a second swing arm 30, a limiting pin 40, and an elastic element 50. The first swing arm 20 and the second swing arm 30 are respectively disposed at the left and right ends of the grip 10. The grip 10, the first swing arm 20, and the second swing arm 30 are integrally formed. The first swing arm 20 and the second swing arm 30 are rotatably mounted on the panel 60. The side of the first swing arm 20 facing the second swing arm 30 has a first wall surface 21. The limiting pin 40 is telescopically fitted onto the first swing arm 20. The limiting pin 40 can extend out of the first wall surface 21 or retract into the first wall surface 21. The elastic element 50 is used to apply elastic force to the limiting pin 40 so that the limiting pin 40 extends out of the first wall surface 21.
[0035] When the user grips the handle 10 to rotate the first swing arm 20 and the second swing arm 30, the limiting pin 40, after being unrestrained by the second wall 61 of the panel 60, will be pushed out of the first wall 21 by the elastic element 50. Thus, even if the handle falls back under gravity, the limiting pin 40 will still abut against the front of the panel 60 (see Figures 1 and 2), preventing the handle 10, first swing arm 20, and second swing arm 30 from fully engaging with the panel 60, leaving a certain gap between the handle 10 and the panel 60. To fully reset the handle, the user needs to press the limiting pin 40 into the first wall 21, allowing continued rotation of the first swing arm 20, etc., until the handle is fully reset (see Figure 9).
[0036] This embodiment discloses a handle anti-pinch structure. A limiting pin 40 is designed on the first swing arm 20. The elastic force applied to the limiting pin 40 by the elastic element 50 allows the limiting pin 40 to extend beyond the first wall surface 21 after the first swing arm 20 rotates outward. Thus, even if the handle falls back, the limiting pin 40 can still abut against the panel 60, thereby limiting the return position of the first swing arm 20 and ensuring that the handle 10, the first swing arm 20, and the second swing arm 30 do not completely abut against the panel 60, avoiding injury to the user's hand and improving safety. Simultaneously, when the handle is in the retracted state, the limiting pin 40, under the action of the elastic element 50, will continuously press against the second wall surface 61 of the panel 60, thus preventing outward springing or vibration after the handle is retracted, improving the stability of the handle when retracted.
[0037] In one embodiment, referring to Figure 5, the first swing arm 20 is provided with a mounting groove 22, and the limiting pin 40 and the elastic element 50 are both provided in the mounting groove 22. By designing the limiting pin 40 and the elastic element 50 in the mounting groove 22 of the first swing arm 20, the internal space of the first swing arm 20 is fully utilized, and the overall structure of the handle is also more aesthetically pleasing.
[0038] In one embodiment, a connecting block 70 is provided inside the first swing arm 20. The connecting block 70 is made of metal and is fixed to the first swing arm 20 by multiple bolts. The connecting block 70 covers the outside of the mounting groove 22 and has a through hole 71, limiting its extension outside the through hole 71. By designing the connecting block 70 on the first swing arm 20, the structural strength of the rotational connection between the first swing arm 20 and the panel 60 can be improved, thereby avoiding the problem of deformation of the first swing arm 20 during use and improving the service life and stability of the handle. Of course, a connecting block 70 is also fixed at the corresponding position on the second swing arm 30.
[0039] In one embodiment, the outer wall of the limiting pin 40 is provided with a limiting flange 41. When the limiting flange 41 abuts against the side of the connecting block 70 away from the second swing arm 30, the limiting pin 40 is in a fully extended state. Under the limiting action of the limiting flange 41, the limiting pin 40 can be prevented from disengaging from the first swing arm 20.
[0040] In one embodiment, the elastic element 50 is a spring, with its two ends abutting against the bottom of the mounting groove 22 and the limiting pin 40, respectively. The bottom of the mounting groove 22 has a limiting protrusion 23, and the elastic element 50 is sleeved over the limiting protrusion 23. Under the limiting action of the limiting protrusion 23, the elastic element 50 will not shift within the mounting groove 22, thus maintaining its connection with the limiting pin 40 and improving the stability of the extension and retraction of the limiting pin 40.
[0041] In one embodiment, a recessed relief groove 42 is formed on the side of the limiting pin 40 opposite to the second swing arm 30, and the elastic member 50 extends into the relief groove 42. The relief groove 42 can increase the effective length of the elastic member 50 within a limited space, thereby increasing the elastic force of the elastic member 50. At the same time, during the retraction of the limiting pin 40, the elastic member 50 will not interfere with the movement of the limiting pin 40, thus allowing the limiting pin 40 sufficient space to retract into the first wall surface 21.
[0042] In one embodiment, the end of the limiting pin 40 facing the second swing arm 30 has a hemispherical structure. The hemispherical design reduces the contact area between the limiting pin 40 and the second wall surface 61, thereby reducing the frictional resistance. It also reduces the risk of scratching the panel 60.
[0043] This embodiment also provides a generator set including the aforementioned anti-pinch handle structure. Because it employs the aforementioned anti-pinch handle structure, it has the same working principle and technical effect as the anti-pinch handle structure in the above embodiments, and will not be described again here.
[0044] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
