Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage power supplies, and in particular relates to a high-power energy storage power supply pull rod fixing structure. Background Art

[0002] As people's outdoor activities increase, energy storage power supplies that power various electrical equipment in outdoor activities are becoming more and more popular. In order to increase the storage capacity of energy storage power supplies and increase the charging speed, the power of energy storage power supplies is getting bigger and bigger. As the power increases, the volume and weight of energy storage power supplies are also getting bigger and bigger. Therefore, wheels are generally set at the bottom of the energy storage power supply and a pull rod is set on the outer shell of the energy storage power supply to pull the energy storage power supply. In this way, the pull rod is subjected to a large force. The connection between the pull rod and the outer shell of the energy storage power supply is easy to loosen or fall off directly after long-term use, which affects the service life of the product. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a high-power energy storage power supply pull rod fixing structure to solve the technical problem that the existing high-power energy storage power supply pull rod is subjected to a large force, and the connection between the pull rod and the energy storage power supply housing is easy to loosen or fall off directly after long-term use, which affects the service life of the product.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A high-power energy storage power supply pull rod fixing structure, comprising: an energy storage power supply housing, a pull rod telescopically arranged on the energy storage power supply housing and connected to the energy storage power supply housing, a reinforcing member arranged around the outside of the pull rod and having two ends respectively connected to the energy storage power supply housing, capable of pressing the pull rod and fixing it to the power supply housing;

[0008] The present application arranges a reinforcement on the pull rod, and the two ends of the reinforcement are connected to the energy storage power supply casing to press the pull rod and fix it to the power supply casing. In addition, the pull rod itself is connected to the power supply casing, which can form a double insurance fixation and disperse the force at the connection between the pull rod itself and the power supply casing, thereby avoiding the problem of loosening and falling off due to the local large force on the connection.

[0009] In some embodiments, the reinforcement ring is provided at the upper end of the pull rod;

[0010] Since the pull rod is generally connected to the energy storage power supply casing at the lower end, arranging the reinforcement piece at the upper end of the pull rod can form a symmetrical structure at the connection with the lower end, which can bear the force symmetrically and avoid the problem of loosening and falling off due to the local large force on the connection.

[0011] In some embodiments, the reinforcement member includes: an arc-shaped ring-shaped portion arranged on the outside of the pull rod and a connecting portion connected to both ends of the ring-shaped portion and extending horizontally, and mounting seats connected to the connecting portion are respectively provided at both ends of the corresponding reinforcement member on the energy storage power supply housing.

[0012] In some embodiments, the ring-mounted portion is provided with a slot, and the position corresponding to the pull rod and the ring-mounted portion is protruded outward to form a limit block that is engaged in the slot;

[0013] Since the pull rod is generally pulled upward when in use, the force acting on the connection between the lower end of the pull rod and the energy storage power supply casing is relatively large and is easy to loosen. By providing a limit block on the pull rod and opening a slot on the reinforcement, the limit block is embedded in the slot for limiting. In this way, when the pull rod is pulled upward, the force can be transmitted to the reinforcement through the limit block. The reinforcement disperses the force acting on the lower end of the pull rod and the energy storage power supply casing, reduces the force acting on the connection between the pull rod and the energy storage power supply casing, and avoids the problem of falling off. In addition, even if the lower end of the pull rod is loosened, the pull rod will not directly fall out due to the limiting action of the limit block, causing the energy storage power supply to fall off.

[0014] In some embodiments, the reinforcement member is made of metal;

[0015] Since the metal reinforcement has a higher hardness, its service life can be extended.

[0016] In some embodiments, the limit block is in a downwardly inclined inclined structure;

[0017] The surface of the limit block is set to an inclined structure, and the limit block can be quickly inserted into the card slot for limiting.

[0018] In some embodiments, the energy storage power supply housing is symmetrically provided with engaging members on both sides of the corresponding pull rod;

[0019] The pull rod can be further strengthened and fixed by adding a clamping piece.

[0020] In some embodiments, the pull rod includes: a plurality of telescopic tube sections that are mutually sleeved and a handle connected to the uppermost tube section, wherein two sides of the connection between the handle and the telescopic tube section contract inwardly to form an arc-shaped structure;

[0021] The connection between the handle and the pipe section is set to a curved arc structure so that both sides of the connection fit better with the fingers, thereby improving the comfort when pulling. BRIEF DESCRIPTION OF THE DRAWINGS
