Description

Technical Field

[0001] This invention relates to the field of engineering machinery parts technology, specifically to a handle device that effectively prevents the horn wire from breaking. Background Technology

[0002] During the operation of construction machinery, the horn installed on the control handle is an important safety warning component. By pressing the horn button on the handle, an audible warning signal can be emitted to people in the vicinity, reminding them to pay attention to the operation of the equipment and avoid approaching the danger zone. In collaborative operation scenarios, the horn can also be used to convey specific instructions to assist in completing work tasks.

[0003] To achieve a clean and aesthetically pleasing wiring harness layout, the speaker signal transmission harness is typically integrated with the handle rod, with the handle rod and speaker harness housed together within a folding dust cover. However, during prolonged handle operation, the sharp edges of the nuts on the handle rod inside the dust cover continuously scrape against the speaker harness, causing it to easily wear down and break. This can lead to speaker signal transmission failure, severely impacting the safety of construction machinery operation. Current handle designs do not effectively address this issue, necessitating the design of a new handle device that structurally prevents the speaker wires from being worn by the nuts, ensuring its proper functioning. Utility Model Content

[0004] The present invention aims to provide a handle device to prevent horn wire breakage. By optimizing the handle structure design, it effectively prevents the horn wire from breaking due to friction with the nut on the handle rod, ensuring stable transmission of horn signals and improving the safety of engineering machinery operation.

[0005] Specifically, a handle device for preventing horn wire breakage includes a handle rod, a horn wire harness, and a protective structure. The protective structure includes thick adhesive and heat shrink tubing. The thick adhesive is wrapped around the nut on the handle rod, and the thickness of the adhesive is approximately equal to the radial height of the nut on the handle rod, forming a relatively flat surface in the nut area of ​​the handle rod. The heat shrink tubing tightly wraps the thick adhesive and the nut together. After being shrunk by a heat gun, the heat shrink tubing adheres tightly to the handle rod. Both the horn wire harness and the handle rod are encased in a folding dust cover. The protective structure on the handle prevents the wire harness from directly contacting the nut, thus preventing the protruding nut edges on the handle from scraping against adjacent horn wire harnesses during handle operation.

[0006] Furthermore, the thick adhesive is foam adhesive, and the thick adhesive is wrapped around the handle rod several times according to the thickness of the nut.

[0007] Furthermore, the heat shrink tubing is made of high-temperature resistant and wear-resistant materials, and the protective wrapping layer formed after shrinkage has high stability.

[0008] The present invention has at least the following beneficial effects:

[0009] Significant protective effect: The invention effectively eliminates the height difference between the nut and the handle rod through the buffer filling layer, making the handle rod form a relatively flat surface in the nut area; the protective wrapping layer forms a smooth, strong and protective overall structure, preventing the nut's sharp edges from scratching the horn wire harness, significantly reducing the risk of horn wire breakage and extending its service life.

[0010] Simple and practical structure: This protective structure is an improvement on the existing handle structure. It is easy to install, does not change the original operation mode and function of the handle, and does not require modification of the speaker wiring harness. It has good practicality and operability. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Furthermore, in the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In this invention, "connection" and "fixing" should be interpreted broadly.

[0015] In existing handle devices, to achieve a simple and aesthetically pleasing wiring harness layout, the horn sound signal transmission harness is usually integrated with the handle lever. The handle head 12 is equipped with a horn button, and the horn harness is connected to the internal terminal of the handle head. The horn wire extends to the handle base and is connected to the vehicle's alarm horn. To improve the dustproof performance of the handle device, the handle lever 11 between the handle head and the handle base is wrapped together with the horn wire in a folded dust cover. The handle lever is equipped with a connecting nut. When the driver operates the handle head to rotate the handle lever, the corner of the nut 2 on the handle lever will scrape against the adjacent horn wire, causing it to wear and break, affecting the output of the horn signal.

[0016] The handle device for preventing horn wire breakage of the present invention, as shown in the figure, adds a protective structure to the handle bar. The protective structure includes thick adhesive 34 and heat shrink tubing 35. The thick adhesive 34 is wrapped around the nut 2 on the handle bar. The thickness of the thick adhesive is equivalent to the radial height of the nut on the handle bar. Through the filling of the thick adhesive, a relatively flat surface is formed on the handle bar in the nut area.

[0017] The heat shrink tubing 35 tightly wraps the thick adhesive and nut together. After being evenly shrunk by a heat gun, the heat shrink tubing adheres tightly to the handle. The entire assembly wrapped by the heat shrink tubing forms a smooth and sturdy whole. The protective structure on the handle effectively prevents the horn wire from directly contacting the nut, and prevents the protruding nut edges on the handle from scraping against the adjacent horn wire harness during operation.

[0018] In one embodiment, the thick adhesive is foam adhesive, which has good elasticity. Depending on the radial thickness of the nut on the handle rod, the foam adhesive can be wrapped around the nut twice to make the nut area flatter and buffer the friction between the nut and the horn harness.

[0019] In one embodiment, the heat shrink tubing is made of high-temperature resistant and wear-resistant material. The protective wrapping layer formed after shrinkage has high stability and can firmly hold the thick adhesive to the handle bar for a long time without falling off.

[0020] This invention proposes a method for preventing speaker wire breakage, comprising the following steps:

[0021] S1. Fill with thick glue. Use thick foam tape to wrap around the handle bar nut. The thickness of the foam glue is equivalent to the radial height of the nut on the handle bar.

[0022] S2. Install the heat shrink tubing, then attach the heat shrink tubing to the handle rod, wrapping the nut and the thick rubber together.

[0023] S3. Curing the heat shrink tubing: Use a heat gun to evenly shrink the heat shrink tubing so that it tightly wraps around the handle.

[0024] The handle device for preventing horn wire breakage of the present invention adds a protective structure to the existing handle, making it easy to install without changing the original operation and function of the handle, and without requiring any modification to the horn wiring harness. It has good practicality and operability. The protective structure is stable and reliable, ensuring that the horn wiring harness does not wear and break, effectively protecting the safety of surrounding personnel and ensuring the smooth operation of work, thus improving the safety and reliability of engineering machinery operation.
