Description

Ultra-short sleeve structure

Technical Field

The invention relates to an ultra-short sleeve structure, in particular to a technology applied to the field of hand tools, which is mainly used for dismounting and locking a screw and a nut.

Background

In the generations of industrial development, the hand tool is the best helper indispensable for many people, and until now, under the progress of science and technology, the hand tool still has a place, no matter the household electrical appliance is assembled and installed, and the furniture is assembled and disassembled, and during many working processes, the hand tool can provide the fastest and most convenient operation mode, however, the types of the hand tool are eight-door, different tools for working are different, and what should be discussed now is that the common ratchet tool 30 and the sleeve 40 are used, most of the assembly and disassembly of any article are clamped and fixed through the matching of the screw 50 and the nut 60, but the normal operation mode is that the ratchet tool 30 is sleeved on the head 501 and the nut 60 of the screw 50 through the assembly of the sleeve 40 indirectly, and then the disassembly is realized through the repeated swinging or rotating (the operation modes of different ratchet tools 30 are different) and the disassembly is realized through the normal operation mode, The screw 50 and the nut 60 are screwed tightly, however, the operation of this method is that the screw 50 is arranged in a normal direction, the normal direction refers to a place where the head 501 of the screw 50 is within the sight of the constructor, and the operation can be performed only by aligning the sleeve 40 with the head 501 of the screw 50, but sometimes because of the design relationship of the object, the installation of the screw 50 must be reversed, so that the nut 60 is in the sight of the constructor, and the head 501 of the screw 50 is hidden under the object (as shown in fig. 6 and 7).

In the above-mentioned arrangement of the screw 50 and the nut 60, the constructor must make the threaded portion 502 of the screw 50 penetrate into the sleeve 40, so as to make the sleeve 40 be sleeved in the nut 60, and then achieve the screwing operation, but the size of the screw 50 is not small, the length and thickness of the threaded portion 502 are not uniform, and in addition, the hole inside the general sleeve 40 is designed into two different sizes, one end of the hole is used for sleeving the ratchet tool 30, the other end of the hole is sleeved on the head 501 of the screw 50 and the nut 60, and in addition, according to the standard tolerance size specification of the international sleeve, three specification lines are respectively defined from the top end to the bottom end of the sleeve 40 in fig. 6, which are respectively L1, L2 and L3, wherein the distance from L1 to L2 is greater than the distance from L1 to L3, which is the size inside the international specified sleeve 40, so that when the general sleeve 40 is sleeved in from the threaded portion at one end of the screw 502 of the screw 50, the end of the threaded portion 502 is limited by the smaller hole of the sleeve 40, so that the sleeve 40 cannot be smoothly fitted with the nut 60, and the constructor must select and replace the sleeve 40 again, which not only consumes time and physical strength, but also causes problems such as falling and loss of the sleeve 40 due to frequent replacement, and completely fails to meet the efficiency of the construction operation. Therefore, those skilled in the art should make various efforts to consider and improve the above-mentioned problems.

In view of the above situation, the present inventors have invested much time in studying related knowledge, comparing the merits with each other, conducting research and development of related products, and going through many experiments and tests, and finally have developed a "super short sleeve structure" to improve the above drawbacks, so as to meet the needs of the public.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a kind of ultra-short type bush structure, its suit is in the ratchet spanner, it includes a body, this body is divided into a joint section and a brake section, and another perforation runs through joint section and brake section, and this perforation is further divided into a joint section, a changeover portion and a drive section, wherein this joint section suit ratchet spanner, and this drive section is the head, nut of the suit screw, and both ends of this changeover portion communicate joint section and drive section respectively, and form a first shoulder between this joint section and changeover portion, and form a second shoulder between changeover portion and the drive section; the screw thread section of the screw penetrates through the drive section of the through hole of the body and abuts against the first shoulder, and the screw cap is sleeved in the drive section and abuts against the second shoulder, so that screwing and unscrewing of the screw cap can be smoothly achieved.

According to the above-described main technique, a further technique is that the perforated coupling section is a square hole in cooperation with the ratchet wrench, the hole pattern of the transition section is a circular hole, and the hole diameter of the transition section is smaller than or equal to the diagonal length of the coupling section.

According to the above-described main technique for the present invention, a further technique is to provide at least one caulking groove on the hole wall of the coupling section for coupling and fixing to the ratchet wrench.

According to the main technique described above for the invention, a further technique consists in that the first shoulder is located further flush with at least one caulking groove bottom edge.

According to the main technique described above for the present invention, a further technique is that an axis X1 is defined on the top surface of the joint section, the center of the groove of the joint section provided with at least one caulking groove defines an axis X3, the transition section defines an axis X2, the second shoulder defines an axis X4, the hole length of the transition section defines a height H, and the relationship between the transition section and the body is as follows

(X3 to X4), the hole length of the driving section defines a height h, and the comparison between the transition section and the driving section is as follows

In order to clearly illustrate the above objects and functions of the present invention, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to fig. 1 to 5, the present invention relates to an ultra-short socket structure, which is assembled to a ratchet wrench 10, it comprises a cylindrical body 1, the body 1 is divided into a joint section 11 and a brake section 12, a through hole 13 is further provided to penetrate the joint section 11 and the brake section 12, and the through hole 13 is further divided into a combination section 131, a transition section 132 and a driving section 133, wherein the coupling section 131 is located at the coupling section 11 and is engaged with the ratchet wrench 10, the driving section 133 is a head 201 of the engaging screw 20 and a nut 30, and two ends of the transition section 132 are respectively connected to the coupling section 131 and the driving section 133, a first shoulder 134 is formed between the connecting section 131 and the transition section 132, a second shoulder 135 is formed between the transition section 132 and the driving section 133, the hole diameter of the transition section 132 is larger than the side length of the connecting section 131, and the hole length of the transition section 132 is larger than one fourth of the hole length of the driving section 133; the threaded section 202 of the screw 20 is inserted from the driving section 133 of the through hole 13 of the body 1 and abuts against the first shoulder 134, and the nut 30 is inserted into the driving section 133 and abuts against the second shoulder 135, so as to achieve smooth screwing and unscrewing of the nut 30.

When the user uses the ratchet wrench 10 to assemble the main body 1, the engaging section 131 is engaged with the ratchet wrench 10, the driving section 133 is then aligned with the screw 20 mounted on the object (the locking of the screw 20 and the nut 30 is reversed, as shown in fig. 4 and 5), the threaded section 202 of the screw 20 is passed through the driving section 133 of the body 1 to the transition section 132, when the driving section 133 can be engaged with the nut 30, the user can rotate the nut 30 to tighten or loosen the nut 30 relative to the screw 20, thereby completing the construction operation, as shown in fig. 4 and 5, the threaded section 202 of the screw 20 can penetrate the transition section 132, so that the body 1 can sink more and can not be pushed by the threaded section 202, the nut 30 can be really sleeved, so that the continuous selection and replacement of a user can be reduced, the time and the physical strength are saved, and the efficiency of construction operation is maintained; after the body 1 is assembled with the screw 20, the end of the threaded section 202 of the screw 20 will abut against the first shoulder 134, the height of the body 1 assembled with the screw 20 is limited by the formation of the first shoulder 134, and the position of the nut 30 can be more reliably aligned, and the second shoulder 135 can provide a reliable abutment for the body 1 against the nut 30, and the nut 30 can be screwed by the hole-type engagement of the driving section 133.

Continuing from the above description, the hole pattern of the coupling section 131 is a square hole matching with the ratchet wrench 10, the hole pattern of the transition section 132 is a circular hole matching with the threaded section 202 of the screw 20, and further the hole diameter of the transition section 132 is smaller than or equal to the diagonal length of the coupling section 131, that is, the hole diameter of the transition section 132 defines a length D, and the diagonal length of the coupling section 131 defines a length D, as shown in fig. 3, and the comparison relation between the transition section 132 and the coupling section 131 is D > D, so that when the body 1 is sleeved from the threaded section 202 of the screw 20, the threaded section 202 of the screw 20 can be inserted into the transition section 132 and stop at the second shoulder 135, and the threaded section 202 of the screw 20 is prevented from colliding with the ratchet wrench 10, so as to protect the screw 20 and the ratchet wrench 10 from being used. In addition, an axis X1 is defined on the top surface of the joint section 11, the joint section 11 is provided with at least one slot 2, the slot center defines an axis X3, the transition section 132 defines an axis X2, the second shoulder 135 defines an axis X4, the hole length of the transition section 132 defines a height H, and the relationship between the transition section 132 and the body 1 is as follows

The distance from X3 to X4, the hole length of the driving section 133 defines a height h, and the comparison between the transition section 132 and the driving section 133 is as follows

h, comparing the present invention with the international specified sleeve 40 listed in the prior art, it can be seen that the present invention forms three stages of different sizes of apertures, providing that the threaded section 202 of the screw 20 can pass through the transition section 132, and the driving section 133 can be firmly engaged with the head 201 of the screw 20, thereby greatly shortening the distance of the body 1 to be suitable for taking out the screw 20 having the shorter threaded section 202. Finally, in order to allow the body 1 to be surely combined with the ratchet wrench 10, it is preferable thatAt least one caulking groove 2 is further formed on the inner wall surface of the combining section 131 of the through hole 13 of the body 1, and the first shoulder 11 and the bottom edge of the at least one caulking groove 2 are arranged in alignment with each other, and since the driving end 101 of the ratchet wrench 10 is provided with the elastic member as in the prior art, it is not described in detail, and the elastic member is clamped against the at least one caulking groove 2 to firmly and firmly mount the body on the ratchet wrench 10, so that the operation of the user is smooth, and the problem of loss caused by the falling-off of the body 1 is avoided, as shown in fig. 3.

To summarize, with the combination between the body 1 and the ratchet wrench 10, a user can use the ratchet wrench 10 to drive the screw 20 to be screwed, locked and unlocked by inserting the through hole 13 of the body 1 through the threaded section 202 of the screw 20, so that the threaded section 202 of the screw 20 enters the driving section 133 and then reaches the transition section 132 until the driving section 133 can be securely sleeved on the nut 30, and the arrangement of the through hole 13 of the body 1 improves the problem that the conventional socket 40 only has a hole section for allowing the ratchet tool 30 to be sleeved on the head 501 of the screw 50 and the nut 60, and the threaded section 502 of the screw 50 with an upside down can not be penetrated, so that the socket 40 must be selected and replaced continuously, which wastes time and physical strength. In addition, the screw 50 with the shorter thread portion 502 cannot be taken out of the conventional socket 40, so that the present invention improves the socket 40 of the prior art, and removes part of the thickness of the interior thereof to form the transition section 132, so as to form a three-stage hole pattern, so that the screw 20 can pass through the transition section without being blocked and limited, and therefore, the present invention has substantial progress and practicability, and is more suitable for the use of the general users.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
