Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of handles, in particular to a lightweight shock-absorbing semi-hollow handle. Background Art
[0002] In daily life, especially in woodworking, hammers and axes are often needed to hammer and strike nails. Current handles are generally made of wooden rods or iron rods. However, due to the lack of shock protection, the handles are prone to vibrate the operator's hands during use. This vibration effect can easily cause damage to the operator's palms, or even wear the skin and cause fatigue. Therefore, existing handle materials usually include wood, glass fiber, etc. Glass fiber is a composite material with glass fiber and its products as reinforcing materials and synthetic resin as a matrix material.
[0003] The existing fiberglass handle is a combination handle. When the fiberglass rod is used as the handle material, an integral injection molding method is adopted to extend the fiberglass rod to the end of the hammer handle and to the tail. Compared with plastic materials, the fiberglass rod is more expensive and heavier, and has certain requirements for the fiberglass material.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lightweight shock-absorbing semi-hollow handle is proposed, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of the utility model is to provide a lightweight shock-absorbing semi-hollow handle to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightweight shock-absorbing semi-hollow handle, comprising a nylon handle and a shock-absorbing hollow cavity, an injection-molded end is provided at one external end of the nylon handle, and a shock-absorbing hollow cavity is provided at the other external end of the nylon handle, a glass fiber rod hollow cavity portion extends inwardly from the injection-molded end portion, the shock-absorbing hollow cavity extends to the front end position of the glass fiber rod hollow cavity portion, a glass fiber rod body is embedded in the injection-molded end portion, and the glass fiber rod body is inserted into the glass fiber rod hollow cavity portion until it contacts the innermost side of the shock-absorbing hollow cavity.
[0007] Furthermore, the nylon handle is provided with a hammer head mounting tenon near the outer wall of the injection molding end.
[0008] Furthermore, anti-slip hand lines are provided on both sides of the outer wall of the nylon handle.
[0009] Furthermore, hanging holes are provided on both sides of one end of the shock-absorbing hollow cavity, and the hanging holes penetrate the outside of the nylon handle.
[0010] Furthermore, the shock-absorbing hollow cavity extends inwardly to the front end of the nylon handle.
[0011] The utility model provides a lightweight shock-absorbing semi-hollow handle, which has the following beneficial effects:
[0012] 1. In the utility model, the entire handle is made of nylon material, and a glass fiber rod body is passed through the front end of the middle part of the handle. The hollowing method reduces the injection volume, ensures the connection strength of the entire handle, and ensures the structural stability during assembly;
[0013] The fiberglass rod extends to the front end of the nylon handle. The rear nylon handle adopts a hollow structure, which can reduce production costs. While ensuring the strength of the handle, it can also increase the shock absorption performance of the nylon handle. In addition, the nylon handle can be recycled repeatedly, while the fiberglass rod is difficult to recycle. Compared with reducing the use of fiberglass rods, it can greatly reduce production costs and operational production difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
