Abstract
Description
Technical Field
[0001] The utility model mainly relates to a pull handle structure for convenient forming.
Background Art
[0002] Pull handles are often used to be installed on framed glass doors, and are made of stainless steel or aluminum alloy. Generally, symmetric pull handles are arranged on both the front and back sides of the glass door. In the existing production process of pull handles, the metal parts are generally integrally processed and formed. This method is usually applicable to the situation where the shape of the pull handle is relatively simple and the size is unified; the advantage of integral processing is that it can reduce the assembly steps, improve production efficiency, and in some cases, better structural strength can be obtained; however, integral processing may not be applicable to pull handles with complex shapes or those that require personalized customization, especially the structure with nuts inside the pull handle and connection holes inside the through cavity of the pull handle; in view of this, we propose a new pull handle structure, which can reduce production complexity, be more convenient for processing and forming, and reduce production costs.
Content of the Utility Model
[0003] To solve at least one of the above problems, the utility model proposes a new structural solution. The following technical solutions are adopted for a pull handle structure for convenient forming:
[0004] A pull handle structure for convenient forming, which includes a cylindrical part, a housing, a first sealing plate, a second sealing plate and an inner core part. The cylindrical part has a through cavity, and the through cavity penetrates the cylindrical part;
[0005] A nut is welded to the outer end face of the cylindrical part, and the cylindrical part is connected to the inner core part so that the nut is clamped between the inner core part and the cylindrical part; the housing has an access cavity, and the front end, the rear end and the bottom end of the housing are all in an open state, and the connected cylindrical part and inner core part are fixedly connected in the access cavity,
[0006] The first sealing plate is fixedly connected to the front end of the housing to partially close the front end of the housing, and the second sealing plate is fixedly connected to the rear end of the housing to completely close the rear end of the housing.
[0007] Preferably, the overall shape of the housing is U-shaped or V-shaped.
[0008] Preferably, the first sealing plate is provided with a semi-circular concave position to cooperate with the through cavity of the cylindrical part to expose at the front end of the housing.
[0009] Preferably, the end of the through cavity of the cylindrical part located inside the housing is located at the rear end position of the housing, and the second sealing plate is connected to the end of the through cavity to close the end of the cylindrical part.

[0012] The beneficial effects of the present utility model compared with the background technology are as follows:
[0013] To simplify the production complexity and make it more convenient for processing and forming, the present utility model proposes a pull foot structure with convenient forming, which includes a cylindrical member, a housing, a first sealing plate, a second sealing plate, and an inner core member. Each component is an independent structure and can be processed separately. The complex structure is split into simple structures, which is more convenient for forming. After each component is formed, they are welded to each other to form an integral body. If the overall processing method is adopted, it is very difficult to process the through-hole connection hole, and at the same time, nuts cannot be made inside the housing. Therefore, after adopting the split structure of this solution, the connection hole can be directly processed on the cylindrical member, and at the same time, the nut can be accurately connected to the connection hole, and then the inner core member can be accurately connected to the nut. In this way, the alignment is extremely convenient and is also conducive to processing; after the cylindrical member is connected to the inner core member through the nut, it is welded inside the housing, and the housing is hermetically sealed front and back with the first sealing plate and the second sealing plate, and then it can be processed and formed, greatly reducing the production difficulty and reducing the production cost. It has the advantages of simple structure, compact cooperation, and reasonable design; therefore, it is a product with excellent technical and economic performance.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.
[0021] A preferred embodiment provided by the present utility model is as Figures 1 to 4 shown, a pull foot structure for convenient forming, which includes a cylindrical member 1, a housing 2, a first sealing plate 3, a second sealing plate 4, and an inner core member 5. The cylindrical member 1 has a through cavity 11, and the through cavity 11 penetrates the cylindrical member 1;
[0022] A nut 6 is welded to the outer end surface of the cylindrical member 1, and the cylindrical member 1 is connected to the inner core member 5 so that the nut 6 is clamped between the inner core member 5 and the cylindrical member 1; the overall shape of the housing 2 is U-shaped or V-shaped, and the V-shaped is the same as the U-shaped, and the V-shaped is omitted in the drawings. In this embodiment, the U-shaped is taken as an example. The housing 2 has an access cavity 21, and the front end, rear end, and bottom end of the housing 2 are all in an open state, and the connected cylindrical member 1 and inner core member 5 are fixedly connected in the access cavity 21,
[0023] The first sealing plate 3 is fixedly connected to the front end of the housing 2 to partially close the front end of the housing 2, and the second sealing plate 4 is fixedly connected to the rear end of the housing 2 to completely close the rear end of the housing 2. The first sealing plate 3 is provided with a semi-circular recess 31 to cooperate with the through cavity 11 of the cylindrical member 1 to expose at the front end of the housing 2; the end of the through cavity 11 of the cylindrical member 1 located inside the housing 2 is located at the rear end position of the housing 2, and the second sealing plate 4 is connected to the end of the through cavity 11 to close the end of the cylindrical member 1.
[0024] The inner core member 5 is provided with a first connection hole 51 and a second connection hole 52, and both the first connection hole 51 and the second connection hole 52 penetrate the inner core member 5. The cylindrical member 1 is provided with a connection hole 12, and the connection hole 12, the screw hole of the nut 6, and the first connection hole 51 are located on the same straight line and are interconnected, facilitating locking members such as screws to penetrate from the inner core member 5 into the through cavity 11.

Each component is an independent structure and can be processed separately. The complex structure is split into simple structures, which is more convenient for forming. After each component is formed, they are welded to each other to form a whole. If the overall processing method is adopted, it is very difficult to process the connection hole 12 of the through cavity 11, and at the same time, it is impossible to make a nut 6 inside the housing 2. Therefore, after adopting the split structure of this solution, the connection hole 12 can be directly processed on the cylindrical part 1, and at the same time, the nut 6 can be accurately connected to the connection hole 12, and then the core part 5 can be accurately connected to the nut 6. In this way, the alignment is extremely convenient and beneficial to processing. After the cylindrical part 1 is connected to the core part 5 through the nut 6, it is welded inside the housing 2, and the housing 2 is hermetically sealed front and back with the cooperation of the first sealing plate 3 and the second sealing plate 4, then it can be processed and formed, greatly reducing the production difficulty and production cost.
