In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] The specific structure of the energy storage power supply of the present utility model is described below with reference to the accompanying drawings.
[0035] The utility model discloses an energy storage power supply, referring to Figure 1 , Figure 2 and Figure 3 As shown, the energy storage power supply includes a handle 100, a rotating shaft 200, an elastic sleeve 300 and a housing 500. The housing 500 has an axial hole 510 and a clamping ring 520 arranged around the axial hole 510. The handle 100 is provided with a matching hole, and the rotating shaft 200 is rotatably arranged in the axial hole 510. One end of the rotating shaft 200 extends out of the axial hole 510 and is inserted into the matching hole. Figure 4As shown, the elastic sleeve 300 is sleeved on the rotating shaft 200 and limited in the clamping ring 520. The outer peripheral wall of the elastic sleeve 300 is frictionally matched with the inner side wall of the clamping ring 520, and the inner peripheral wall of the elastic sleeve 300 is frictionally matched with the outer side wall of the rotating shaft 200. It can be understood that in the actual assembly process, the elastic sleeve 300 is sleeved on the rotating shaft 200, and then one end of the rotating shaft 200 is inserted into the matching hole through the shaft hole 510, so that the elastic sleeve 300 is installed inside the clamping ring 520 to complete the installation. The assembly is very convenient, and the structure of the entire energy storage power supply is very simple, and the manufacturing cost is low. At the same time, since the elastic sleeve 300 is sleeved on the rotating shaft 200 and limited in the clamping ring 520, the outer peripheral wall of the elastic sleeve 300 and the inner side wall of the clamping ring 520 are frictionally matched, and the inner peripheral wall of the elastic sleeve 300 and the outer side wall of the rotating shaft 200 are frictionally matched, so that the elastic sleeve 300 is squeezed along its circumferential and radial directions at the same time, so that the elastic sleeve 300 and the rotating shaft 200 and the shell 500 generate an interaction force, and the force is converted into a damping effect on the handle 100, thereby avoiding a violent collision between the handle 100 and the shell 500 and generating a loud impact sound, and the user experience is better. In addition, through the rotating shaft 200 and the elastic sleeve 300, the handle 100 is integrated into the shell 500, reducing the use of parts and reducing the cost of parts control and maintenance.
[0036] refer to Figure 6 As shown, the outer peripheral wall of the elastic sleeve 300 is provided with a plurality of ridges 310 distributed at intervals along the circumference of the elastic sleeve 300. It is understandable that the ridges 310 and the grooves 320 are provided on the outer peripheral wall of the elastic sleeve 300, so that a whole circle of wave-shaped patterns can be formed on the outer peripheral wall of the elastic sleeve 300, thereby increasing the acting force between the elastic sleeve 300 and the clamping ring 520, and in the process of rotating the handle 100 so that the elastic sleeve 300 is squeezed, since the grooves 320 are formed between the two ridges 310, the elastic sleeve 300 can be squeezed into the grooves 320 of the wave-shaped patterns, thereby increasing the damping effect of the clamping ring 520 on the elastic sleeve 300, thereby improving the user satisfaction. At the same time, when installing the elastic sleeve 300, the elastic sleeve 300 can also be squeezed into the grooves 320 of the wave-shaped patterns, thereby increasing the convenience of assembling the handle 100 and improving the assembly yield of the handle 100.
[0037] refer to Figure 6As shown, the inner circumferential wall of the elastic sleeve 300 is provided with a plurality of ridges 310 distributed at intervals along the circumference of the elastic sleeve 300. It is understandable that the ridges 310 and the grooves 320 are provided on the inner circumferential wall of the elastic sleeve 300, so that a whole circle of wave-shaped patterns can be formed on the inner circumferential wall of the elastic sleeve 300, thereby increasing the acting force between the elastic sleeve 300 and the rotating shaft 200, and in the process of rotating the handle 100 so that the elastic sleeve 300 is squeezed, since the grooves 320 are formed between the two ridges 310, the elastic sleeve 300 can be squeezed into the grooves 320 of the wave-shaped patterns, thereby increasing the damping effect of the elastic sleeve 300 on the rotating shaft 200 body, thereby improving the user's satisfaction. At the same time, when installing the elastic sleeve 300, the elastic sleeve 300 can also be squeezed into the grooves 320 of the wave-shaped patterns, thereby increasing the convenience of assembling the handle 100 and improving the assembly yield of the handle 100.
[0038] Further, refer to Figure 6 As shown, along the axial direction of the elastic sleeve 300, both ends of the inner circumferential wall and / or the outer circumferential wall of the elastic sleeve 300 are chamfered. It is understandable that the chamfer does not require an additional fool-proof structure, which reduces manpower input and saves labor costs on the one hand, and facilitates the elastic sleeve 300 to enter the clamping ring 520 on the other hand, making assembly smoother.
[0039] refer to Figure 4 As shown, a stop portion is provided at one end of the rotating shaft 200 located inside the housing 500, and the elastic sleeve 300 is sandwiched between the stop portion and the end surface of the shaft hole 510. It can be understood that the stop portion can press the elastic sleeve 300, thereby facilitating an increase in the damping force generated by the elastic sleeve 300 on the rotating shaft 200.
[0040] Further, refer to Figure 4 and Figure 5 The energy storage power supply further includes a gasket 400, which is sleeved on the rotating shaft 200, and the outer diameter of the gasket 400 is larger than the stop portion. The elastic sleeve 300 is sandwiched between the gasket 400 and the end face of the shaft hole 510. It can be understood that by setting the gasket 400 to stop the elastic sleeve 300, the diameter of the stop portion of the rotating shaft 200 can be reduced, thereby reducing the amount of chip processing during the processing of the rotating shaft 200, which can improve product production capacity and reduce product cost. In the embodiment of the utility model, the specific material of the gasket 400 can be selected according to actual needs, and the specific material and thickness of the gasket 400 are not limited here.
[0041] refer to Figure 5 As shown, the shaft diameter of the rotating shaft 200 decreases in a step-like manner from the stop portion, thereby reducing the manufacturing cost of the product.
[0042] refer to Figure 5As shown, the rotating shaft 200 includes a first shaft section 210, a second shaft section 220 and a third shaft section 230 connected to each other, the first shaft section 210 and the second shaft section 220 constitute a stop portion, the end of the third shaft section 230 away from the second shaft section 220 is inserted into the matching hole, and the elastic sleeve 300 is sleeved on the third shaft section 230 and stops at the second shaft section 220, and the gasket 400 is sleeved on the second shaft section 220 and stops at the first shaft section 210. It can be understood that during the processing, the diameters of the first shaft section 210, the second shaft section 220 and the third shaft section 230 are reduced in sequence, the third shaft section 230 can ensure stable insertion with the matching hole, the second shaft section 220 can prevent the elastic sleeve 300 from moving from the second shaft section 220 to the third shaft section 230 along its axial direction, and the first shaft section 210 can prevent the gasket 400 from moving along its axial direction and thus separating from the rotating shaft 200.
[0043] The rotating shaft 200 is interference fit with the matching hole, and the rotating shaft 200 is clearance fit with the shaft hole 510. It can be understood that the interference fit between the rotating shaft 200 and the matching hole can ensure the connection stability between the rotating shaft 200 and the handle 100, and avoid relative rotation between the rotating shaft 200 and the handle 100, and the clearance fit between the rotating shaft 200 and the shaft hole 510 can ensure that the rotating shaft 200 can smoothly rotate relative to the housing 500, thereby ensuring that the handle 100 can smoothly rotate relative to the housing 500.
[0044] Further, refer to Figure 5 As shown, the rotating shaft 200 is provided with a plurality of convex rings 231, and the plurality of convex rings 231 are distributed at intervals along the axial direction of the rotating shaft 200. It is understandable that, in the actual installation process, the plurality of convex rings 231 can ensure that the rotating shaft 200 is stably maintained in the matching hole after being inserted into the matching hole, and avoid the axial movement of the rotating shaft 200, thereby ensuring the connection stability between the handle 100 and the housing 500.
[0045] Furthermore, refer to Figure 5 As shown, the cross-sectional area of the protruding ring 231 gradually decreases in the direction away from the axis of the rotating shaft 200. It can be understood that the protruding ring 231 is formed as a wedge-shaped ring. When the rotating shaft 200 is inserted into the matching hole, the narrow end of the protruding ring 231 is inserted into the matching hole first, and then the wide end enters the matching hole. This ensures that the rotating shaft 200 can be smoothly inserted into the matching hole on the one hand, and on the other hand, it can ensure that the rotating shaft 200 can be stably maintained in the matching hole after being inserted into the matching hole, avoiding the rotating shaft 200 from moving along the axial direction, thereby ensuring the connection stability between the handle 100 and the housing 500.
[0046] In an alternative embodiment, the rotating shaft 200 is provided with an external thread, and the matching hole is formed as a threaded hole. In the actual working process, the rotating shaft 200 can be rotated to be inserted into the matching hole.
[0047] refer to Figure 1 As shown, the handle 100 is a U-shaped structure, which includes a crossbar 110 and vertical bars 120 connected to both ends of the crossbar 110, and each vertical bar 120 is provided with a matching hole. It can be understood that the handle 100 is a U-shaped structure, which can improve the connection stability between the handle 100 and the housing 500, ensuring that the handle 100 can be stably installed on the housing 500, and the U-shaped structure is convenient for users to hold, thereby facilitating users to carry and transport the energy storage power supply.
[0048] Optional, reference Figure 1 As shown, an anti-skid texture 111 is provided in the middle of the crossbar 110. It can be understood that the added anti-skid texture 111 can increase the friction between the handle 100 and the user, thereby facilitating the user's grip, thereby facilitating the user's handling and transportation of the energy storage power supply.
[0049] In some embodiments, a downwardly recessed installation space is provided on the top of the housing 500, and the handle 100 is installed in the installation space. It is understandable that the handle 100 is installed in the installation space, and when the handle 100 is rotated to the storage position, the upper surface of the handle 100 can overlap with the top wall of the housing 500, making the appearance of the energy storage power supply more beautiful.
[0050] The advantages of the energy storage power supply disclosed in the utility model are as follows:
[0051] First: the rotating shaft 200 is made into a stepped design to reduce the cutting amount when processing the rotating shaft 200, improve product production capacity, and reduce product cost;
[0052] Second: the handle 100 is integrated into the housing to reduce the use of parts and reduce the cost of parts management and maintenance;
[0053] Third: the damping force caused by the torsion of the elastic sleeve 300 can be kept uniform and consistent, so as to avoid the handle 100 and the housing 500 from violently colliding and producing a loud impact sound, and the user experience is better, and by adjusting the compression amount of the elastic sleeve 300, the damping effect of different strengths can be achieved;
[0054] Fourth: The structure of the handle 100 is very simple, which reduces the manpower input for assembly, optimizes the assembly process, and improves assembly efficiency.
