Description

Technical Field

[0001] The utility model relates to a handle, in particular to a base handle structure. Background Art

[0002] The handle is a device installed on the door and window sashes to have the function of opening and closing. It is mostly made of aluminum alloy, copper, stainless steel, plastic and other materials, with various forms and sizes. In addition to meeting the requirements of comfortable hand feeling and reasonable force, it also has a decorative effect. Therefore, the materials and shapes are selected as finished products or designed separately according to the requirements of architectural design. The traditional handle and base are an integrated structure. After long-term use, it is easy to have a large gap between the base and the door, and it is likely to become loose and unstable. There is a lack of a product with a more stable and reliable structure to meet the needs of long-term use. Utility Model Content

[0005] The connecting part is provided with an open groove which runs through transversely in the center, the positioning piece is provided with an opening in the center, and a convex block which cooperates with the opening groove is provided on the hole wall of the opening.

[0006] The flanges are arranged in pairs and at intervals.

[0007] The positioning column is provided with a groove on the side for fixed installation.

[0008] A plurality of evenly and symmetrically distributed hollow grooves are arranged in the base.

[0009] Beneficial effects of the utility model: the base handle structure provided by the utility model integrates the base body, uses a retaining spring to firmly assemble some parts together, and uses a coil spring to make the handle rotate relative to the base, thereby changing the traditional transmission form and reducing vibration or looseness.

[0013] like Figure 1-Figure 3 As shown, a base 2 handle structure comprises a handle 1 and a base 2, wherein the base 2 is provided with a socket 3 for installing the handle 1, and the base 2 is provided with an open inner cavity 4 for installing parts on the bottom surface, the socket 3 is communicated with the inner cavity 4, the handle 1 has a connecting portion 5, the connecting portion 5 passes through the socket 3 and extends into the inner cavity 4, and the connecting portion 5 is sleeved with a coil spring 6, a positioning piece 7, a gasket 8 and a retaining spring 9 at one end close to the inner cavity 4, the base 2 is provided with a positioning column 10 and a mounting hole 11 on the wall of the inner cavity 4, the positioning piece 7 is provided with a flange 12 at the outer edge, the two ends of the coil spring 6 elastically abut the flange 12 and the positioning column 10 respectively, the connecting portion 5 is provided with an annular groove 13 for installing the retaining spring 9, the gasket 8 is provided between the retaining spring 9 and the positioning piece 7, and the positioning piece 7 and the gasket 8 are locked in the axial direction by the retaining spring 9, and the connecting portion 5 and the positioning piece 7 rotate in conjunction. After the connecting portion 5 of the handle 1 is inserted into the base 2, the coil spring 6, the positioning plate 7, the gasket 8 and the retaining spring 9 are installed in sequence. The retaining spring 9 is used to tighten the handle 1 in the axial direction, and the coil spring 6 is used to reduce the shaking in the radial direction. The design of the positioning column 10 allows the base 2 to be directly fixed on the door body or the door lock, that is, the base 2 no longer rotates with the handle 1. The overall structural design is simple and compact. While ensuring the normal rotation of the handle 1, the handle 1 and the base 2 maintain a tight assembly relationship.

[0014] The connecting portion 5 is provided with a transversely penetrating opening groove 14 in the center, and the positioning piece 7 is provided with an opening hole 15 in the center. The hole wall of the opening hole 15 is provided with a protrusion 16 that cooperates with the opening groove 14. The opening groove 14 and the protrusion 16 can rotate synchronously in the circumferential direction after being embedded. The setting of the gasket 8 reduces the wear of the positioning piece 7 on the retaining spring 9. The flanges 12 are arranged in pairs and at intervals, which can play a certain installation restriction role on the coil spring 6 and avoid failure after dislocation and detachment. The positioning column 10 is provided with a cut groove 17 for fixed installation on the side, which is conducive to the direct plug-in fixation of the base 2 and will not easily disengage and rotate. The base 2 is provided with a number of evenly and symmetrically distributed hollow grooves 18 to ensure structural strength and reduce the weight of the base 2.

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings.
