Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology for small household appliances, and more specifically, to a high-precision, wear-resistant locking structure. Background Technology
[0002] Small appliances refer to household appliances other than high-power appliances. Generally, these small appliances consume relatively little electricity or have a small size, hence the name "small appliances." There are many types of small appliances, such as hair dryers, electric fans, electric heaters, and humidifiers. Handheld vacuum cleaners, for example, are small in size and provide convenient services for families, making them a classic example of small appliances.
[0003] Handheld vacuum cleaners come in various structures and types. Simpler types are operated by gripping the handle, which moves the main unit to perform the vacuuming action. However, some lack protective structures around the handle, making it susceptible to wear and tear from repeated use, friction, and external impacts. Therefore, securing protective parts to the outside of the handle can extend its lifespan. Utility Model Content
[0004] In view of the problems in the related technologies, this utility model proposes a high-precision and wear-resistant locking structure to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows: a high-precision and wear-resistant locking structure, including a main body and a gripping part disposed on the main body, a protective shell symmetrically disposed on the outer wall of the gripping part, an adjustment mechanism disposed between the protective shells and symmetrically disposed therebetween, and a positioning mechanism disposed at the connection of the protective shells.
[0006] As a further optimization, the adjustment mechanism includes a groove, a mounting sleeve, and a return spring. The groove is symmetrically excavated on both sides of the lower protective housing. The mounting sleeve is provided at the bottom of the groove cavity and extends to the top of the lower protective housing. The return spring is provided at the bottom of the mounting sleeve cavity.
[0007] As a further optimization, the top of the reset spring is fixedly connected to the bottom of the protective housing located above it.
[0008] As a further optimization, the positioning mechanism includes a positioning groove and a positioning block. The positioning groove is symmetrically excavated on the top surface of the lower protective shell, and the positioning block is symmetrically arranged on the bottom of the upper protective shell.
[0009] As a further optimization, the inner wall size of the positioning groove matches the size of the positioning block and is designed for a snap-fit connection.
[0010] As a further optimization, a wear-resistant pad is connected to one side of the protective shell; preferably, the wear-resistant pad is a silicone pad.
[0011] As a further optimization, the protective shell has a concave structure, and the parts are spliced together to form a hollow rectangular structure, and the gripping part is disposed inside the hollow rectangular structure.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] This high-precision, wear-resistant locking structure combines multiple mechanisms, including a protective shell, a positioning mechanism, an adjustment mechanism, and a wear-resistant pad, to form a new locking structure on the grip. Components within multiple adjustment ends activate and adjust the structure, allowing multiple protective shells to be spliced together. The protective shells are also connected via engagement components within the positioning ends. The spliced protective shells are stably locked onto the grip and, in conjunction with the wear-resistant pad, are well-positioned on the grip, providing protection. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit its scope.
[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 4 As shown, a high-precision, wear-resistant locking structure includes a main body 1 and a gripping part 2 disposed on the main body 1. Protective shells 3 are symmetrically arranged on the outer wall of the gripping part 2. Adjustment mechanisms 4 are arranged symmetrically between the protective shells 3, and positioning mechanisms 5 are provided at the connection points of the protective shells 3. A wear-resistant pad 6, which is a silicone pad, is connected to one side of the protective shell 3. The protective shells 3 have a concave structure and are spliced together to form a hollow rectangular structure. The gripping part 2 is disposed within the hollow rectangular structure. By activating and adjusting the components within the multiple adjustment mechanisms 4, the multiple protective shells 3 are spliced together, and the splicing of the protective shells 3 is also achieved by engaging the components within the positioning mechanisms 5. The spliced protective shells 3 are fixed on the gripping part and cooperate with the wear-resistant pad 6, effectively protecting the gripping part 2. In addition, while preventing damage to the grip, the protective shell 3 can be stably fitted onto the grip 2 through the adjustment mechanism 4 and the positioning mechanism 5, and the connection can be precisely made to ensure the stable connection of each mechanism, avoid mutual offset and continuous friction, and have excellent wear resistance.
[0024] Specifically, the adjustment mechanism 4 includes a groove 7, a mounting sleeve 8, and a return spring 9. The groove 7 is symmetrically cut on both sides of the lower protective shell 3. The mounting sleeve 8 is provided at the bottom of the inner cavity of the groove 7 and extends to the top of the lower protective shell 3. The return spring 9 is provided at the bottom of the inner cavity of the mounting sleeve 8. The top of the return spring 9 is fixedly connected to the bottom of the upper protective shell 3. The protective shell 3 is located outside the grip 2. When the upper protective shell 3 is pulled, the protective shell 3 transmits the pulling force to the return spring 9, causing the return spring 9 to deform, so that the two protective shells 3 are spliced together and fit against the outer wall of the grip 2.
[0025] The positioning mechanism 5 includes a positioning groove 10 and a positioning block 11. The positioning groove 10 is symmetrically cut into the top surface of the lower protective shell 3, and the positioning block 11 is symmetrically arranged at the bottom of the upper protective shell 3. The inner wall size of the positioning groove 10 matches the size of the positioning block 11 and is engaged. When the protective shells 3 are spliced, the positioning block 11 engages into the positioning groove 10, making the connection between the two spliced protective shells 3 more stable. The spliced protective shell 3 is fixed on the grip and cooperates with the wear-resistant pad 6, which effectively protects the grip 2.
[0026] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the protective shell 3 is first placed on the outside of the grip 2, and then the upper protective shell 3 is pulled. The protective shell 3 transmits the pulling force to the return spring 9, causing the return spring 9 to deform, so that the two protective shells 3 are spliced together and attached to the outer wall of the grip 2. When the protective shells 3 are spliced, the positioning block 11 is engaged in the positioning groove 10, so that the connection between the two spliced protective shells 3 is more stable. The spliced protective shell 3 is fixed on the grip and cooperates with the wear-resistant pad 6, which effectively protects the grip 2.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
