The present invention relates to a socket structure, more particularly to a socket structure for installing and removing tires, and the socket structure has a better structural strength and is capable of extending the service life effectively.
As the name suggests, a socket dedicated for installing and removing tires is a special tool used for installing and removing tires and the socket may be operated together with a relative power tool such as a pneumatic or electric tool for an expected installation or removal of a screw which is secured to a tire. In short, the socket usually requires a strong structural strength to withstand a high-strength torsional stress for a long period of time.
With reference to
Although such conventional socket has been used for years, most users found that the outermost edge of the sheathing action section 41 may be easily damaged by inadvertent fall or accidental collision. In addition, the sheathing action section 41 has an insufficient strength/load capacity, and thus may be cracked or damaged easily. These products give users bad experience with a short service life. Obviously, such products require further improvements.
An object of the invention is to apply an integral thickening technique to the peripheral surface of a sheathing action section of a socket to improve the structural strength without increasing the manufacturing cost or complicating the manufacturing procedure. The invention not just effectively extends the service life only, but also achieves the effects of preventing a severe crack of the sheathing action section and ensuring the safety of the users.
According to the invention, a socket structure for installing and removing tires includes a socket having a sheathing action section, a neck buffer section and a power plug section. The sheathing action section includes an axial polygonal action hole, and the power plug section has an axial square hole and a radial through hole. The sheathing action section has an edge thickening and reinforcing portion disposed at a front end thereof, and a primary thickening and reinforcing portion disposed at a rear end thereof.
The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
To make it easier for our examiner to understand the objective of the invention, its features, and advantages, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
With to
Wherein, the edge thickening and reinforcing portion 27 is capable of withstanding unexpected collision or hitting and preventing its deformation or damage, and the primary thickening and reinforcing portion 28 is disposed adjacent to the neck buffer section 22, so that after the sheathing action section 21 is cracked by an external stress exceeding to its load capacity, the primary thickening and reinforcing portion 28 can control the cracking range of the material, so that the sheathing action section 21 will not be cracked completely, so as to prevent the cracked pieces from shooting at the users, and ensure the safety of use.
In addition, the neck buffer section 22 has an effect of providing instantaneous response to torsional stresses and high strength and toughness to the material of the socket when a force is exerted to the socket 20, so as to buffer the external force effective and reduce the risk of cracking the material. However, the design of such buffering technique is a well-known art used in various different hand tools and related assemblies, and thus will not be described in details.
