Description

Heteromaterial bonded structure

technical field

The utility model provides a tool grip, in particular to a combination structure of different materials.

Background technique

Please refer to Fig. 10, the handle 11 (or body) of various commonly used tools is made of P.O.M. plastic steel, nylon, ABS, PE, or PE plastic, etc. The handle 11 is made of metal material, and the handle 11 is made of the aforementioned material, which is hard in texture, poor in grip and easy to slip.

Please refer to Fig. 11, the more advanced system utilizes soft injection-grade rubber (TPR) to coat the hard handle body 12 to form a soft layer 13, which provides a more comfortable grip and better However, the soft TPR rubber only has a better affinity with nylon plastic, and other materials are not applicable, and metal materials are even more inapplicable. In addition, a number must be set at the appropriate position of the grip body 12 of hard nylon plastic. a through hole 121, so that the soft layer 13 on both sides of the handle body 12 can be connected to each other by means of the connecting rib 14 when the handle body 12 is coated with soft material, so that the soft layer 13 will not be in contact with the hard layer when it is subjected to torsional force The grip body 12 is detached to improve the strength of the combination of different materials.

Although the aforementioned improved structure can improve the bonding strength of different materials, the hard material is limited to nylon plastic, which has limited applicability and high production cost. This is the first disadvantage.

Secondly, the handle body 12 of the hard material must be provided with several through holes 121 to improve the bonding strength of the soft and hard materials. This structure can only be used for screwdrivers, wrenches, etc. , Other types of tool handles or other items are not applicable, such as pneumatic tools, electric tools, air dust guns, etc., must have air passages or structures inside the handles, which is the second shortcoming.

A soft combination body, the soft combination body is formed inside the hard body and protrudes from the through groove to form at least one extension body, and the extension body is integrated with the soft combination body inside the hard body.

Wherein, the extension body has extensions on one, two, three or four sides of the hard body.

Wherein, the extension body has a covering portion on the outer peripheral surface of the hard body.

Wherein, the extension body has extension parts on both sides of the hard body.

Wherein, the hard body is a plastic hard body.

Wherein, the hard body is a metal hard body.

Wherein, the metal hard body is a zinc hard body.

Wherein, the metal hard body is an aluminum hard body.

Wherein, the metal hard body is an aluminum alloy hard body.

Therefore, good torsional and shear strength effects can be provided.

Compared with the effect of the previous technology: the utility model pours the soft combination through the through hole, and the soft combination can be integrally formed with the hard body in a single-sided, double-sided, three-sided, four-sided or fully covered manner, and the The material of the hard body, whether it is a variety of hard plastics or metals, can be integrally formed by pouring, without being limited by the material. The extension body is integrated with the soft combination inside the hard body to provide a good Torsion and shear strength, the extension will not have the defect of detachment.
