Description

Technical Field

[0001] This application relates to the field of refrigerator handle technology, and in particular to an in-mold brushed plastic base structure and a refrigerator handle having the in-mold brushed plastic base structure. Background Technology

[0002] Some existing refrigerator handles have a pair of brackets installed at both ends of the handle tube for easy connection to the door panel. However, these brackets are made of die-cast zinc alloy, which is costly to manufacture. In addition, the brackets are directly fixed to the handle tube and cannot be adjusted, making them very inconvenient to use. Utility Model Content

[0003] The purpose of this application is to provide an in-mold wire drawing plastic seat structure that is simple in structure, easy to assemble and disassemble, flexible in adjustment, and low in manufacturing cost, as well as a refrigerator handle having the in-mold wire drawing plastic seat structure.

[0004] To achieve the above objectives, this utility model provides an in-mold drawing plastic seat structure, including a plastic seat body, an inner plug, a fixing screw, a side hole screw, and a mounting stud;

[0005] The plastic base body has a first cavity with a downward-extending opening and a second cavity with a horizontally extending opening. The first cavity has a boss, and the top of the inner plug is engaged with the boss. The inner plug has a third cavity with a downward-extending opening. The nut of the fixing screw is located in the third cavity, and the threaded part of the fixing screw passes through the top of the inner plug and extends into the second cavity. The nut of the mounting stud is located in the third cavity, and the threaded part of the mounting stud extends to the outside of the third cavity and the first cavity. The side-hole screw is threadedly connected to the outer wall of the inner plug, and the side-hole screw can extend into the third cavity and tighten the nut of the mounting stud.

[0006] To facilitate the assembly and disassembly of the inner plug and the boss, the inner wall of the boss has a snap-fit ​​strip, and the outer wall of the inner plug has a snap-fit ​​groove, and the snap-fit ​​strip can be snapped into the snap-fit ​​groove.

[0007] To guide the inner plug during engagement, the top of the inner plug has an arc-shaped guide portion, which is positioned above the engagement groove.

[0008] To prevent the seat structure from rotating after assembly, the top of the inner plug has an L-shaped limiting platform that extends into the second cavity.

[0009] To facilitate the installation and removal of the side-hole screws, the outer wall of the plastic base body is provided with a waist-shaped through hole that allows the side-hole screws to pass through.

[0010] This utility model also provides a refrigerator handle, including a handle tube, with the above-mentioned in-mold drawn plastic seat structure installed at both ends of the handle tube.

[0011] To facilitate the assembly and disassembly of the handle tube from the aforementioned base structure, threaded holes are provided at both ends of the handle tube to allow for threaded connection with fixing screws.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] (1) The use of a plastic base and metal parts as a connection method solves the problem that the tensile strength of the zinc alloy die-cast base and handle tube does not meet the requirements after assembly;

[0014] (2) Compared with zinc alloy die-cast bases, plastic bases have lower manufacturing costs;

[0015] (3) The plastic base and handle tube are not completely fixed after assembly. There is a gap and they can swing left and right. However, they will automatically straighten after being installed on the customer's door. With this design, the plastic base shell will only serve a decorative purpose, which can better ensure that the flatness of the product meets the customer's requirements. Attached Figure Description

[0018] Figure 3 This is a cross-sectional view of the in-mold drawing plastic seat structure in the embodiments of this application. Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0020] Example 1:

[0021] like Figure 1 The refrigerator handle shown includes a handle tube 1, which is a hollow cylindrical structure. In-mold drawn plastic seat structures 2 are detachably installed at both ends of the handle tube 1.

[0022] Example 2:

[0023] like Figure 2 , Figure 3 The in-mold drawing plastic seat structure shown includes a plastic seat body 201, an inner plug 202, a fixing screw 203, a side hole screw 205, and a mounting stud 204;

[0024] Specifically, the inner body 201 of the plastic seat has a first cavity extending downward and a second cavity extending horizontally. The first cavity has a boss 206, the inner wall of which has a pair of snap-fit ​​strips 2061. The outer wall of the inner plug 202 has a pair of snap-fit ​​grooves 2022, and the snap-fit ​​strips 2061 can snap into the snap-fit ​​grooves 2022. The top of the inner plug 202 has an arc-shaped guide portion 2023, which is positioned above the snap-fit ​​grooves 2022. The inner plug 202 has a third cavity extending downward. The nut portion of the fixing screw 203 is located in the third cavity, and the threaded portion of the fixing screw 203 penetrates the top of the inner plug 202 and extends into the second cavity. The handle tube 1 is provided with a... The inner plug 202 has a threaded hole 101 that is threadedly connected to the fixing screw 203. The top end of the inner plug 202 has a through hole 2025 that allows the threaded part of the fixing screw 203 to pass through. The top end of the inner plug 202 has an L-shaped limiting platform 2021 that extends into the second cavity. The nut part of the mounting stud 204 is located in the third cavity. The threaded part of the mounting stud 204 extends into the third cavity and outside the first cavity. The side hole screw 205 is threadedly connected to the threaded hole 2024 on the outer wall of the inner plug 202. The side hole screw 205 can extend into the third cavity and tighten the nut part of the mounting stud 204. The outer wall of the plastic seat body 201 has a waist-shaped through hole 2011 that allows the side hole screw 205 to pass through, which facilitates the adjustment of the position of the side hole screw 205.

[0025] The in-mold wire drawing plastic seat structure of this utility model is made of plastic, which has a lower manufacturing cost compared to zinc alloy die-cast seats. The boss 206 inside the plastic seat and the snap-fit ​​groove of the inner plug 202 are assembled together with a clearance fit, which facilitates disassembly and assembly. The L-shaped limiting platform 2021 on the inner plug 202 is used to prevent rotation after the seat assembly and handle tube 1 are assembled. The end of the handle tube 1 has a notch into which the L-shaped limiting platform 2021 can be inserted, which serves as a limiting function. The handle tube 1 and the inner plug 202 are assembled together with fixing screws 203. In order to prevent loosening, the fixing screws are... The locking surface of 203 is designed in a tooth shape, and the threaded bottom hole on the inner plug is directly made to avoid subsequent machining. During installation, the mounting stud 204 is fixed to the door panel, and then the handle is locked onto the mounting stud 204 with the side hole screw 205 with anti-loose adhesive. This completes the assembly of the entire handle. The plastic base and handle tube are not completely fixed after assembly, and there is a gap that allows it to swing left and right. However, it will automatically align itself after being installed on the customer's door. With this design, the plastic base shell will only serve a decorative purpose, which can better ensure that the flatness of the product meets the customer's requirements.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
