Description

Improved Martian plug magnetic sleeve structure

This creation is about a Martian plug magnetic sleeve; in particular, it relates to a modified Martian plug magnetic sleeve structure that can be quickly assembled inside the sleeve body and effectively prevents the weakening of the magnetic force of the magnetic attraction unit.

According to the general sleeve tools are mostly used in the field of disassembly or assembly of polygonal bolt heads or nuts. Among them, the well-known Martian plug sleeve is a hollow long shape, one end of the sleeve is A quadrangular socket for inserting the four corners of a wrench tool (such as a ratchet wrench, a slide bar, a post, etc.), and the other end of the sleeve is a polygonal socket with a socket on the Mars plug. After using the four corners of the wrench tool to insert the socket of the quadrilateral socket, then force the wrench tool to drive the socket to rotate, and the polygonal socket at the other end of the socket can directly force the Mars plug to rotate until the The Martian plug is loosened and disassembled. However, after the Martian plug sleeve is disassembled, the Martian plug often comes out of the socket after it is removed, and even after the Martian plug is dropped to a narrow position, the user's The inconvenience is a big headache for them.

In order to solve the above-mentioned problems, some industry developers have developed a hollow magnetic element directly bonded to the inner bottom surface of the polygonal socket part of the sleeve in an adhesive manner. Although such a structure can fix the magnetic element to the sleeve, Inside the tube and can be unloaded The lower Martian plug can be taken out with the sleeve, but its production and assembly or use will cause the following problems: Because the magnetic attraction element is directly bonded to the inside of the metal sleeve, after a period of manufacture, regardless of its Whether it is used or not, it will cause the magnetic change of the magnetic element to weaken due to the direct contact of the magnetic element with the metal sleeve, and it will even cause no magnetic force at all.

As mentioned above, because the magnetic element is made of a hard material, plus the error value produced during manufacturing, it often breaks and cannot be used when it is squeezed into the sleeve. Then greatly increase its cost and another major problem.

In view of this, the creator is actively developing and researching, and in order to improve the lack of the conventional Martian plug magnetic sleeve, the creator has developed and designed after years of hard work in research and experiment based on years of experience in manufacturing such products. The structure of the magnetic sleeve of the Martian plug created by this creation is expected to benefit all consumers and manufacturers.

The main content of the modified structure of the magnetic sleeve of the Martian plug in this creation is to provide a seat that can be pressed against the sleeve at the same time by the convex part of the base body being restricted by the inner wall surface of the sleeve body. The inner wall surface of the body is clamped and clamped at the ring recess of the limit seat, and the magnetic suction unit can be fitted and assembled at the shaft hole of the limit seat. In this way, it can not only enable the assembler to compare Light force can complete the assembly, making its assembly more convenient and fast, in order to greatly increase its assembly rate and production capacity, at the same time, it can also overcome the breakage or loss of the conventional magnetic suction unit during the assembly process, so as to Significantly reduce its cost and ensure that it has been assembled in the limit seat The magnetic attraction unit inside does not cause the problem of weakening of the magnetic force, and then it increases its market competitiveness and market share as its progressive claim.

It is located on the two ends of the sleeve body 1 and the connecting hole 10 is connected to the sleeve connecting hole 11; the base body 2 is preferably made of plastic material and includes at least a ring on the outer wall surface The convex part 20 abuts against the inner wall surface of the sleeve hole 11 of the sleeve body 1 and an accommodation hole 21 for inserting one end of the limiting seat 3 and penetrating between the two end faces of the seat body 2; The convex portion 20 is formed by a guide surface 201 extending from small to large in size, and a supporting surface 202 formed by connecting the guide surface 201 to abut, as the convex portion 20 receives the part from the sleeve body 1. The basis of the asymptotic compression force formed by the sleeve 11 is set, and the above-mentioned guide surface 201 is an inclined surface, or an inclined cone surface, or an inner arc surface, or a convex arc surface, or a spherical surface. Best; furthermore, the outer contours of the upper and lower sides of the accommodation hole 21 are in a continuous connection state (that is, the outer contour of the accommodation hole 21 on the same horizontal line is continuously connected in a closed loop shape), and the inside of the accommodation hole 21 An axially extending groove 22 is provided on the wall surface, so that the groove 22 can be correspondingly located on the inner side wall of the accommodation hole 21 between two adjacent convex portions 20. It is assumed that after the convex portion 20 is squeezed and displaced by the size limit of the set hole 11, the displacement and deformation amount generated relative to the inner wall surface size of the accommodation hole 21 at the convex portion 20 is absorbed. Also, a radial section groove 23 is provided at the inner wall surface of the accommodation hole 21, and the space height of the section groove 23 is higher than the space height of the convex portion 20; It is made of copper or aluminum, and at least includes a ring recess 30 for pressing and displacing the inner wall surface of the accommodating hole 21 of the base 2 after the convex portion 20 is squeezed, and a magnetic attraction unit 4 Formation class A penetrating shaft hole 31; the magnetic suction unit 4 is provided with a hollow penetrating insertion hole 41 therein, so that the insertion hole 41 can communicate with the shaft hole 31 and the accommodation hole 21 in an aligned manner, So that one end of the Mars plug 5 can penetrate into it and be adsorbed on the inner wall surface of the insertion hole 41 of the magnetic attraction unit 4, so that the Mars plug 5 in a loose state can be fixed to the same as it has been assembled. The magnetic suction unit 4 inside the sleeve body 1 moves and moves; when assembling and using, only the inner diameter dimension of the shaft hole 31 of the stopper 3 made of copper or aluminum material which has been finished by turning is omitted. Larger than the outer diameter of the magnetic attraction unit 4, so that the magnetic attraction unit 4 can be directly arranged in the shaft hole 31 (in other words, the magnetic attraction unit 4 can also be arranged in the fitting with a slight tight fit or static fit. In the shaft hole 31, and in order to make the coupling between the shaft hole 31 and the magnetic suction unit 4 more stable, it can be coated with adhesive on the outer peripheral side of the magnetic suction unit 4 before the assembly and assembly. Insert the magnetic attraction unit 4 directly into the shaft hole 31), so as to ensure that the magnetic attraction unit 4 will not be deformed due to accidental extrusion of the fitted assembly. There is a major loss of damage; at this time, since the inner diameter dimension of the receiving hole 21 of the seat body 2 is slightly larger than the outer diameter dimension of the ring recess 30 of the limiting seat 3, it can be close to the convex After the accommodation hole 21 on the end surface of the base body 2 of the part 20 is directly fitted to the ring recess 30 of the limit seat 3, the base body 2 and the limit seat 3 are then combined to the sleeve of the sleeve body 1. The set hole 11 is inserted until the bottom edge of the set hole 11 touches the guide surface 201 of the convex portion 20 of the base body 2; at this time, since the sleeve body 1 is made of copper or aluminum And the size of the set hole 11 is also fixed. In addition, the base body 2 is made of plastic material; therefore, when the convex portion 20 of the base body 2 is When the guide surface 201 踫 touches the bottom edge of the sleeve hole 11, the bottom edge of the sleeve hole 11 will be pushed away from the guide surface 201 due to the pushing force of the seat body 2 to the inside of the sleeve body 1 continuously. The minimum size of the lens is moved toward its maximum size direction until the bottom edge of the sleeve hole 11 moves to the support surface 202 of the convex portion 20. At this time, the base 2 made of plastic will be subjected to the sleeve by the convex portion 20. It is assumed that the compression of the hole 11 causes a local deformation displacement amount to move inward, so that the accommodation hole 21 at the convex portion 20 also follows the local deformation displacement amount of an inward movement (that is, the accommodation hole). The axially extending groove 22 of 22 can be used to absorb the local deformation size of the accommodation hole 22 moving inward), and the local deformation displacement amount of the inward movement can just move into the limit seat 3 In other words, in the ring groove 30, the accommodation hole 21 deformed and moved by the protrusion 20 can tightly cover the outer side of the ring recess 30 of the limit seat 3. The seat body 2 can abut against the inner wall surface of the sleeve body 1 at the same time and can be clamped against the ring recess of the limit seat 3 30, and the magnetic suction unit 5 can be fitted and assembled at the shaft hole 31 of the limit seat 3, which can not only enable the assembler to complete the assembly with light force, but also make the assembly more convenient and fast. In addition to greatly increasing its assembly rate and production capacity, it can also overcome the breakage or loss of the conventional magnetic suction unit 5 during the assembly process to greatly reduce its cost and ensure that it has been set within this limit. The magnetic attraction unit 5 in the seat 3 will not cause the problem of weakening of the magnetic force, thereby increasing its market competitiveness and market share.

The above are only the preferred embodiments of this creation, and are not intended to limit the scope of implementation of this creation; All equal changes or modifications made by Zheng He Spirit shall be included in the scope of patent application for this creation.
