Description

Technical Field

[0001] The present invention relates to the technical field of switch handles, and in particular to a handle. Background Art

[0002] A handle is a device used to open and close doors. It is usually installed on door panels or window sashes for people to grasp or push and pull. It is usually made of metal, plastic or other materials, and has a shape and size suitable for human hand holding. Door handles are generally fixed on one side of the door, and the door is opened and closed by rotating or pushing and pulling. In addition to making it easier for people to enter and exit the door, door handles also serve to beautify, decorate and protect the facade.

[0003] Most existing door handles are fixed with exposed screws, that is, when installing the door handle, the door handle mounting screws are placed on the back of the door panel, so that the screws are not visible on the front side of the door panel, achieving an aesthetic effect. However, once the door is closed, the screws on the handle can still be seen from the back of the door panel. Although it is convenient for secondary tightening, the screws are easy to loosen after long-term use. At the same time, when viewed from the back of the door panel, the exposed screws reduce the aesthetics of the entire door handle. At the same time, the prior art uses a method of rotating the cover plate, which requires one hand to support the cover plate and the other hand to tighten the screws during secondary tightening, which is inconvenient. Summary of the invention

[0004] The present application provides a handle which is not easy to loosen, has good aesthetics, is easy to tighten even if it is loose, and has excellent use effect.

[0005] To this end, the present application provides a handle, including a mounting base plate, a cover plate rotatably connected to the mounting base plate through a position-limiting clamping assembly, and a grip, the grip is rotatably connected to the mounting base plate after passing through the cover plate, and threaded holes are provided at least at two diagonal positions of the mounting base plate, and a double-head fastener is threadedly connected to the threaded holes; Or the installation base plate is fixedly connected to the cover plate, a screw rod is threadedly connected in the threaded hole, and the end of the screw rod is connected to the cover plate via an elastic fixing component.

[0006] By adopting the above technical solutions: in the first of the above technical solutions, the cover plate is rotatably connected to the mounting base plate through a limiting clamping assembly. When the double-headed fastener is loose, the cover plate can be rotated to reveal the double-headed fastener for tightening. Since the limiting clamping assembly is adopted, the position of the cover plate relative to the mounting base plate can be limited and it can be tightened without manual support, making tightening more convenient. When using double-headed fasteners, both ends can be tightened, further reducing the difficulty of tightening.

[0007] The second technical solution in the present application can fix the end of the screw rod by means of an elastic fixing component, and will not loosen during long-term use.

[0009] By adopting the above technical solution: the relative position of the cover plate and the mounting base plate can be limited by the cooperation of the rotating part and the clamping part. When tightening is required, the position of the cover plate relative to the mounting base plate can be determined after rotating the cover plate to a certain extent, eliminating the need for manual support.

[0010] Optionally, the rotating member includes a rotating disk that cooperates with the stepped circular hole, the rotating disk is provided with a plurality of engaging teeth, the cover plate is provided with an internal thread column, the rotating disk is provided with a through hole, and the screw passes through the through hole and is fixedly connected with the internal thread column.

[0011] Optionally, the clamping member includes at least one spring bean fixed in the mounting base plate, and the end of the spring bean is located between two clamping teeth.

[0012] By adopting the above technical solution: the spring bean is between the two engaging teeth to position the rotating disk, and when the cover plate needs to be rotated, the spring bean can retract, and after rotating into place, the spring bean continues to be engaged between the two engaging teeth, thereby forming a position limit for the cover plate.

[0013] Optionally, the double-headed fastener comprises a threaded rod body, one end of the threaded rod body is provided with a first fastening portion, and the other end of the threaded rod body is provided with a second fastening portion.

[0014] By adopting the above technical solution: the provision of the first fastening part and the second fastening part facilitates fastening the threaded rod from both sides.

[0015] Optionally, the elastic fixing assembly includes a drilling portion arranged at the end of the screw rod and an elastic fixing piece arranged in the cover plate.

[0016] Optionally, the drilling portion includes a tip having a truncated table surface arranged at the end of the screw rod, and an annular inner groove arranged above the tip.

[0017] Optionally, the elastic fixing member includes an elastic rod slidably arranged inside the cover plate, and the end of the elastic rod is provided with an inclined portion that matches the vertebral table surface.

[0018] By adopting the above technical solution: when tightening the screw, the tip of the screw approaches the inclined portion and pushes the elastic rod outward. When the tip passes through the inclined portion and is inserted into the annular inner groove, the screw is clamped to prevent it from loosening.

[0019] Optionally, the cover plate is rotatably connected to the mounting base plate via a sliding assembly.

[0020] Optionally, the sliding assembly includes an arc-shaped sliding groove provided on the mounting base plate, and the cover plate is provided with sliding ridges cooperating with the arc-shaped sliding groove.

In the first of the above technical solutions, the cover plate is rotatably connected to the mounting base plate through a limit clamping assembly. When the double-headed fastener is loose, the cover plate can be rotated to reveal the double-headed fastener for tightening. Since the limit clamping assembly is used to limit the position of the cover plate relative to the mounting base plate, it can be tightened without manual support, making tightening more convenient; using double-headed fasteners, both ends can be tightened, further reducing the difficulty of tightening; in the second technical solution of this application, the end of the screw can be fixed by an elastic fixing assembly, and it will not loosen during long-term use.

[0023] 2. The relative position of the cover plate and the mounting base plate can be limited by the cooperation of the rotating part and the clamping part. When tightening is required, the position of the cover plate relative to the mounting base plate can be determined after rotating the cover plate to a certain extent, eliminating the need for manual support.

[0024] 3. When tightening the screw, after the tip of the screw approaches the inclined portion, push the elastic rod outward. When the tip passes through the inclined portion and is inserted into the inner annular groove, the screw is clamped to prevent it from loosening. BRIEF DESCRIPTION OF THE DRAWINGS
