Abstract

A composite wrench comprises a main body, a ring body and a reinforcement piece. The main body has a through hole formed at one end. The ring body is fixed into the through hole of the main body and has an inner toothed hole. The reinforcement piece is accommodated inside of the main body and has a fixation joint section tightly fixing the ring body and a reinforcement section extending from the fixation joint section towards the other end of the main body. Therefore, when a torsion force is applied onto the main body, the reinforcement piece can enhance structural strength of the main body to increase service life and practicality.

Description

200815160 IX. Invention Description · Technical Field of the Invention

The invention relates to a wrench, in particular to a compound wrench. [Prior Art] Referring to Figure 1, the case of the announcement No. M295558 is taken as an example, the wrench i main

It consists of a body U made of plastic and a ratchet made of metal material. The body 11 has a head portion lu and a handle portion (1) opposite thereto, and a polygonal hole 113 extending through the head portion (1) along the - Korean line. The spine η is embedded in the polygonal hole 113' and has a shape formed at: ^ Π 3 122. Therefore, since the body Π is made of plastic, the overall reset of the yoke wrench 1 can be greatly and salty, and the ratchet ring 12 is the polygonal hole 113 of the polygonal body 11 The fitting can avoid stress concentration, so that the head portion 111 of the crucible body 11 has sufficient structural strength to overcome the torsion force during the rotation to prevent the ratchet ring 12 from coming off.咅Juntian gives the body 11 a torsion, except in the body! In the case where there is stress concentration between the head U1 and the 5th ratchet ring 12, between the body ij force 隹卩U1 and the shank 112, even the shank 112 may also have a negative: medium Therefore, the structural strength of the plastic body u is often not, and the torque is not described, but there is a lack of deformation and fracture, which is less practical. [Invention content] 200815160 Therefore, the object of the present invention is to provide A compound wrench that increases structural strength. Therefore, the composite wrench of the present invention comprises a body and a reinforcing member. The body and the right newspaper are reported to the village. The consistent hole of 卩. The ring body is fixed in the through hole of the body and has an inner hole. The body is disposed in the body, and has a tight junction, a consolidated portion that fastens the core body, and a reinforcing portion that extends from the other end of the body. . 2 The force effect is to strengthen the structural strength of the body by the reinforcing member, thereby improving the service life and practicability. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be described in detail in a detailed description of a preferred embodiment of the McCaw chart.

Clear presentation. TJ includes -: m Figure 3, the composite wrench of the present invention - a preferred embodiment package _, - core 3, a reinforcing member 4 and a limit group 5 〇 " two body 2 has formed at one end - a head 21 formed in a further - and a force 'handle 22, and a consistent bore 23 through the head 21 along an axis. In the embodiment '', the body 2 is made of plastic. < Figure 4, the body 3 is a through hole 23 fixed to the body 2 = has an internal perforation 31 extending along the axis, and a non-zero portion 32 formed on the one side of the circumference ^ The circular portion 3..."3, and defined in the non-circular portion 32 and the two sides 34" on both sides. The non-circular portion 32 has a relatively constitutive material. Everything is 321. In the present embodiment, the ring body 3 is made of gold 200815160. The reinforcing member 4 is received in the body 2 and has a consolidating portion 41 for fastening the ring body 3, and the consolidating portion 41 is along the The body 2 has a shank portion extending in the longitudinal direction of the reinforcing portion 42' and a first notch 43 formed at the end of the reinforcing portion 42 and opposite to the solid θ junction portion 41. Referring to Figures 5 and 6, the consolidating portion 41 abuts against the ring body 3 and the shoulder portion 34, and has a ring piece 412 surrounding the non-circular portion μ and defining a non-circular hole 411. The non-circular hole 4 is in contact with the flat surface 321 of the ring body 3 to obtain a limit. The reinforcing portion a has a groove 42ι formed on the - surface and extending in the longitudinal direction, and a reinforcing rib 422 formed on the other surface with respect to the groove 421. The reinforcing rib 422 is configured to raise the structural strength of the reinforcing portion 42. In this embodiment, the reinforcing member* is stamped from an iron plate. Referring to FIG. 3 and FIG. 4 , the limit group 5 has a first limiting member 51 盥 - a second limiting member 52 . The first stopper 51 is fixed in the shank 22 of the body 2 and has a second notch that engages with the first notch 43 and supports the reinforcing portion 42 of the reinforcing member 4. The second limiting member 52 is sleeved between the through hole 23 of the body 2 and the non-circular portion 32 of the ring body 3, and is firmly fixed to the ring body 3 by the reinforcing portion 41 of the reinforcing member 4 Shoulder 34. In the present embodiment, the limit group 5 is made of plastic. When manufacturing, as shown in FIG. 3, the ring body 3, the reinforcing member ^ and the limit group 5 can be pre-assembled, and then, as shown in FIG. 4, preset into a mold cavity 61 of a mold 6' The first component and the third limiting member 51, 52 of the limiting group 5 respectively lose the consolidating portion 41 of the reinforcing member 4 and the reinforcing portion. 42 m, although the extension member 4 has an appropriate length extension, it can still be placed in the injection operation or in the 200815160::, the plastic is adhered to the cavity 61 to cover the ring body 3 and the limit group 5, forming The body 2, after the mold is released, when the body 2 is subjected to a torsion force, the body 2 and the handle 22 can have sufficient degree of knot by the body 2%, strong: 4'. The phenomenon of load stress concentration avoids the deformation of the body 2. ,

According to the above, the composite wrench of the present invention has the following advantages and advantages. 1. Since the reinforcing member 4 and the limiting member 5 of the present invention are completely hidden in the body 2, the overall aesthetics are not affected. , and can effectively improve the structural strength of the body 2, so that the present invention is more practical, and can improve the use of the brother's life " 〇 2 · based on the description, the reinforcing member 4 is completely hidden in the body 2

P so. The reinforced member 4 does not require surface treatment such as grinding, rust prevention, plating, etc., and the manufacturing cost is also low. The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the scope of the patent application and the month of the invention. The simple equivalent changes and modifications made by the children of the Valley are still within the scope of the patents of the present invention.
