TECHNICAL FIELD
[0001] The utility model relates to a door handle structure, in particular to a door handle structure with detachable handle and handle connecting rod. BACKGROUND
[0002] The handle is widely used in various household appliances or furniture as a device for opening and closing doors, and has various forms and structures. Some door handles only provide a holding function and do not have a door locking function, which are commonly used in many cabinet doors. Another type of door handle not only provides a holding function but also has a rotating function, such as a door locking function through rotation.
[0003] Currently, door handles with rotating function on the market usually include a handle and a handle connecting rod. The handle and the handle connecting rod are an integral whole with different parts. The handle and the handle connecting rod can be integrally formed or welded to form a whole. When installing the door handle, the mounting part between the handle and the door is usually arranged inside the door for decorative effect. The mounting part sometimes contains a riveting structure that cannot be disassembled, which requires the handle and the door to be pre-assembled during production.
[0004] However, the pre-assembled structure of the handle and the door affects the packaging size and increases the product cost due to the large size of the handle protruding from the door surface. When the handle needs to be repaired or replaced, the entire door usually needs to be replaced, causing waste.
[0005] In addition, the handle and the handle connecting rod are fixed together by welding. The welding marks are easily left at the welding position, and the welding gap after welding is not easy to polish, affecting the appearance.
[0006] In some specific occasions, the handle may be an operating part of the equipment, and the door is only a decorative part fixedly installed on the front of the equipment. The handle connecting rod passes through the door and is connected and installed with the internal parts of the equipment. At this time, if the handle and the handle connecting rod are an integral whole that cannot be disassembled, the size of the handle is usually larger than the size of the slot through which the handle connecting rod passes on the door, which makes it impossible to remove the decorative door without removing the handle. In addition, the handle connecting rod is connected and fixed with the internal parts of the equipment, and it is not easy to remove the handle connecting rod from the internal parts of the equipment before the decorative door is removed.

[0046] The specific implementation of the utility model will be further described in detail in combination with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model. Embodiment 1
[0047] As Figures 1-5The utility model provides a handle structure, including handle 1 and handle connecting rod 2 who are connected with each other, handle 1 includes first handle part 11, second handle part 12, connecting rod connecting mouth 13, first handle part 11 and second handle part 12 are all the structure shape of gyration body,
[0048] Second handle part 12 is connected with first handle part 11, one end of handle connecting rod 2 connects external equipment, and the other end passes through connecting rod connecting mouth 13 and connects first handle part 11, and first handle part 11 is connected with second handle part 12.
[0049] The part of handle connecting rod 2 after passing through connecting rod connecting mouth 13, the upper end of which extends upwards and forms connecting rod upper wing 21 fixed distance, and the lower end of which extends downwards and forms connecting rod lower wing 22 fixed distance, the side of connecting rod upper wing 21 forms the angle alpha 1 with the top of handle connecting rod 2, and the angle alpha 1 is obtuse, the side of connecting rod lower wing 22 forms the angle alpha 2 with the bottom of handle connecting rod 2, and the angle of angle alpha 1 is equal to the angle of angle alpha 2, the inner wall of first handle part 11 is connected with connecting rod upper wing 21, the inner wall of second handle part 12 is connected with connecting rod lower wing 22, the height h1 of handle connecting rod 2 is matched with the height h2 of connecting rod connecting mouth 13, when first handle part 11 is connected with second handle part 12, connecting rod connecting mouth 13 fixes handle connecting rod 2 and prevents it from moving in any direction.
[0050] The screw rod 111 is arranged in the central position of first handle part 11, and the screw hole 121 matched with the screw rod 111 is arranged in the central position of second handle part 12, the sunken hole 123 is arranged in first handle part 11, the extending end 122 is arranged in second handle part 12, after the screw rod 111 and the screw hole 121 are matched and screwed, the extending end 122 is matched and connected with the sunken hole 123, and first handle part 11 and second handle part 12 are connected.
[0051] The working principle of the handle structure of the embodiment 1 is as follows:
[0052] By dividing the handle 1 into two parts, a first handle portion 11 and a second handle portion 12, which are screwed together by a screw 111 and a screw hole 121, the distance between the first handle portion 11 and the second handle portion 12 decreases during the screwing process. This tightens the handle connecting rod 2 between the screw 111 and the inner walls of the first handle portion 11 and the second handle portion 12. Furthermore, because the angle ∠α formed by the upper wing 21 and the lower wing 22 of the connecting rod and the middle crossbar is an obtuse angle of 100°, the handle connecting rod 2 becomes increasingly tighter during the screwing process. The inclusion of the insertion end 122 and the countersunk hole 123 prevents gaps from forming between the first handle portion 11 and the second handle portion 12, thus avoiding any aesthetic impact.
[0053] When it is necessary to remove the handle 1, simply rotate the second handle part 12 in the opposite direction to remove the first handle part 11 and the second handle part 12 from the handle connecting rod 2. The structure is simple and easy to assemble and disassemble. Example 2
[0054] like Figures 6-7 As shown, the difference between this embodiment 2 and embodiment 1 is that the connection between the screw 111 and the screw hole 121 is cancelled, and the connection between the first handle part 11 and the second handle part 12 is achieved by setting threads on the extension end 122 and the countersunk hole 123. Example 3
[0055] like Figures 8-9 As shown, in this embodiment 3, most of the second handle part 12 is made solid, a screw 111 is provided at the top center of the solid part, and a screw hole 121 is provided on the inner top wall of the first handle part 11. The rest is basically the same as in embodiment 1. Example 4
[0056] like Figure 10 Compared with Embodiment 1, in Embodiment 4, a first horn 114 and a second horn 124 are respectively provided inside the first handle part 11 and the second handle part 12. The inclination angle of the inner wall of the first horn 114 matches the angle α1 of the upper wing 21 of the connecting rod, and the inclination angle of the inner wall of the second horn 124 matches the angle α2 of the lower wing 22 of the connecting rod. When the first handle part 11 is connected to the second handle part 12, the first horn 114 and the second horn 124 are respectively matched and locked with the upper wing 21 and the lower wing 22 of the connecting rod of the handle connecting rod 2.
