Abstract

The invention relates to a socket head structure, comprising a main body, an engagement member accommodated in the main body, a magnetic body and an elastic member. The main body comprises a first end, a second end, a containing groove, a first abutted edge, a convex ring and a second abutted edge. One end of the engagement member is provided with a receiving slot, a seized part, a plurality of through slots, and a convex collar. Because the largest outer diameter of the seized part is greater than the inner diameter of the convex ring of the main body and the through slots are formed on the seized part, the seized part can be easily compressed through the convex ring of the main body to allow the seized part to be accommodated in the containing groove and capable of shifting a distance between the first and second abutted edges accordingly. The magnetic body is secured in the receiving slot of the engagement member and opposite to the first end of the main body for providing magnetic suction effect. The elastic member is accommodated in the containing groove and elastically resisted between the first abutted edge and the engagement member.

Description

Socket structure

The invention relates to a sleeve joint structure, in particular to a sleeve joint structure which is provided with a body, a sleeve member, a magnetic body and an elastic member, and the magnetic system has the effect of elastic displacement in the body.

As is known in the prior art, a magnetic sleeve joint structure is used, such as U.S. Patent No.: 6925914, which is characterized in that the body 10 is provided with a fitting portion 11 at one end, and the sleeve portion 11 has a hexagonal groove shape. The sleeve portion 11 is provided with a sleeve screwing member. The sleeve portion 11 is provided with a receiving groove 111 and a buckle groove 113. The buckle ring groove 113 is for inserting a C-shaped buckle 40. The structure is provided with a fixing ring 30. The fixing ring 30 is provided with a magnetic body 31. The fixing ring 30, the magnetic body 31 and the elastic member 20 are received in the receiving groove 111. After the body 10 is inserted into the buckle 40, the driving portion 12 at one end of the body 10 is inserted into the pulling end 51 of the sleeve 50, whereby the body is inserted into the buckle 40. The 10 series can attract the screwing member 52 due to the action of the magnetic body 31, and can prevent the screwing member 52 from falling on the body 10 during operation.

But the lack of the patent is based on:

1. The maximum outer diameter of the fixing ring 30 is larger than the inner diameter of the buckle 40. When the assembly is basically set, the buckle 40 is fastened to the buckle groove 113, and the fixing ring 30 is less rigid, so that The retaining ring 30 is inserted into the receiving groove 111 through the retaining ring 40, so that the retaining ring 30 needs to be pressed into the retaining ring 30 to pass through the retaining ring 40. The retaining ring 30 is easily damaged when pressed in, and the operator sets up the operation. The time is inconvenient.

2. The buckle groove 113 of the main body 10 has different sizes according to the size of the body 10. For example, the sleeve portion 11 of the specification 19 mm is a buckle groove 113 of 23 mm inner diameter, and the buckle groove 113 of each size is adopted. It is required to be fastened with each buckle 40 of the same size. In addition to using the lathe processing buckle groove 113 to set different outer diameters when the cutter travels, the buckle 40 also needs to be used in different sizes to different sizes. The buckle groove 113, the conventional sleeve joint structure increases the cost of the lathe buckle groove 113 and the economic benefit of purchasing different buckles 40 to match the different sizes of the buckle groove 113, and increases the buckle 40 Part cost.

3. Please add the explanation of the structure of the patent case as shown in the twelfth figure. The sleeve part 11 of the body 10 is in the form of a hexagonal groove. If the sleeve part 11 is of the specification 19MM, the set is The inner diameter of the joint portion 11 is 19 mm, and the inner diameter of the buckle groove 113 is matched with the distance of 19 MM. The inner diameter of the buckle groove 113 is 23 mm, and the fixing ring 30 is accommodated in the sleeve portion 11. The maximum outer diameter of the fixing ring 30 is also 19MM, and the minimum outer diameter can be set to 18MM, so the outer diameter of the buckle 40 is 23MM, and the inner diameter is 18MM, so the width of the buckle 40 is 2.5MM. The large width of the buckle 40 is relatively difficult to retract and is buckled at the buckle groove 113.

In view of the lack of the structure of the above-mentioned U.S. patent case, the inventor has borrowed years of experience in related industries to finally have a product that is practical and can improve the drawbacks.

The sleeve joint structure of the invention is provided with a body, a sleeve part, a magnetic body and an elastic element, and the sleeve part and the magnetic system have the function of elastic displacement in the body, and can absorb the screw parts and reduce the processing and component cost. .
