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, a buckle ring and an elastic member, so that the magnetic system has the effect of elastic displacement in the body, and the sleeve is assembled. Parts, magnetic bodies, buckles and elastic elements can be set up in advance.

A magnetic sleeve joint structure is used, such as U.S. Patent No.: US6925914, which is characterized in that the body 10 is provided with a fitting portion 11 at one end, and the sleeve portion 11 is in the shape of a hexagonal groove, and the sleeve portion 11 is The sleeve portion 11 is provided with a receiving groove 111 and a buckle groove 113. The buckle groove 113 is embedded in a C-shaped buckle 40, and the sleeve joint 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 element 20 are received in the accommodating groove 111. The elastic element 20 is abutted against the flange 14 and the fixing ring. After the main body 10 is inserted into the buckle 40, the driving portion 12 is inserted into the pulling end 51 of the socket wrench 50, whereby the body 10 is caused by the magnetic body 31. The screwing member 52 can be sucked to prevent the screwing member 52 from falling on the body 10 during operation.

But the lack of the patent is based on:

1. As shown in the first figure, the maximum outer diameter of the fixing ring 30 is greater than the inner diameter of the buckle 40. When the assembly is substantially set, the buckle 40 has been fastened to the buckle groove 113, and the fixing ring 30 is The fixing ring 30 is inserted into the receiving groove 111 through the buckle 40, so that it needs to be pressed into the fixing ring 30 to pass. The buckle 40 is relatively easy to be damaged when the fixing ring 30 is pressed by force, and the operator is inconvenient in setting up the operation.

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 refer to the diagram of the structure of the patent case. The sleeve part 11 of the body 10 is in the shape of a hexagonal groove. If the sleeve part 11 is 19MM, the set is provided. 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 problem to be solved by the invention is that the conventional sleeve connector has a problem that the assembly is not easy, and the sleeve joint structure of the invention is provided with a body, a sleeve member, a magnetic body, a buckle ring and an elastic member, so that the The magnetic body and the sleeve are elastically displaced in the body, and the sleeve, the magnetic body, the buckle and the elastic component can be set in the external phase, and the utility model has the advantages of convenient and rapid assembly. Sex.

Technical means for solving the problem: a sleeve joint structure, comprising: a system having a first end, a second end, a receiving groove, a first abutting edge, a buckle ring groove, the buckle ring groove and the first end end The first part is provided with a first distance; a set of fittings is disposed in the receiving groove, and one end of the fitting is provided with a receiving groove, and the outer periphery of the fitting is provided with a ring-shaped ring groove The ring groove is provided with at least one notch, and the sleeve is provided with a first ring top at the same side of the groove, and a second flange is disposed at the top of the first ring, the first ring The top portion has a second distance, the second distance is the same as the first distance; a magnetic system is fixed in the cavity, the magnetic system is opposite to the first end; and a buckle is fastened in the buckle groove; The elastic component is received in the accommodating groove, the elastic component is elastically abutted between the first abutting edge and the fitting member, and the elastic component is provided with a locking portion at one end, and the locking component is clamped at the ring groove, and the elastic component Limited by the buckle, and the carding portion is limited to the sleeve, so that the sleeve is limited to the body without ejecting.

According to the effect of the prior art, one end of the elastic element is fixed to the first abutting portion of the body and the other end is fastened to the fitting member, and the fitting member and the magnetic body can be elastically displaced in the body. When the first end is sleeved on the screwing member, the screwing member can be magnetically attracted by the magnetic body, and the screwing member does not fall out of the body. The buckle ring can be firstly sleeved on the sleeve member, and the buckle ring is abutted against the second flange, the sleeve member is placed in the receiving groove of the body, because the second distance is equal to the first The distance is such that the buckle is automatically engaged in the buckle groove by aligning the buckle groove. Therefore, the assembly, the magnetic body, the buckle and the elastic component can be assembled in the housing groove of the body before being assembled in the external body, and the assembly action is faster and the assembly convenience is achieved. The first end has a variety of specifications, but the plural specifications The one end is set to a single-size accommodating groove and a buckle groove, and the cost of processing the accommodating groove and the buckle groove can be greatly reduced.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
