Description

Universal sleeve for wrench with elastic root self-resetting top plate planted at bottom of inner cavity

Technical Field

The utility model relates to the field of hardware tools, in particular to a special sleeve for a wrench.

Background

The closest prior art is a common special wrench socket for a four-corner bolt, which is characterized in that:

the special spanner sleeve for the traditional four-corner bolt comprises an inner cavity, wherein the inner cavity belongs to a cuboid space, and the top surface and the bottom surface of the inner cavity are four-fillet square spaces. Note that the lumen is empty and nothing is inside.

Regardless of the specific configuration, the overall appearance of a conventional wrench socket for a lag bolt with an upward opening is a "cap-less box".

The special spanner socket of traditional quadrangle bolt can only carry the quadrangle bolt head of only a specific size.

There is a general need for a universal socket that can grip different sizes of bolt heads.

A single socket is not capable of performing the task of disassembling and assembling the bolt, and a manual wrench handle or an electric wrench handle must be provided, that is, the present invention belongs to only one structural component of a complete manual wrench (or a complete electric wrench).

Disclosure of Invention

The utility model aims to provide a special universal sleeve for a wrench, which can be disassembled and assembled with bolts of various sizes, and in order to achieve the aim, the utility model adopts the following technical scheme:

first, the general technical solution of the utility model is explained

1. The utility model belongs to a universal sleeve for a wrench, which is characterized in that an inner cavity bottom is fully planted with a self-reset top plate with an elastic root,

the universal sleeve for the wrench belongs to a barrel with an opening at one end and an inner cavity 1 sealed at the other end, and the universal sleeve is particularly placed with the opening facing upwards for observation for convenience of explanation:

the shape of the universal sleeve for the wrench is not limited.

The inner cavity 1 belongs to a cuboid space, and the top surface space and the bottom surface space of the inner cavity are both rectangular (or square), and can also be rounded rectangular (or rounded square) if necessary.

The bottom surface of the inner cavity 1 is also planted with an elastic root self-resetting top plate 2 in a full land, each elastic root self-resetting top plate 2 at least comprises a top plate body 3 positioned at the upper part and an elastic root 4 positioned at the lower part and resetting from the top, wherein:

each top plate body 3 is a thin plate made of a hard material that is not fragile, and the overall shape is generally rectangular but not limited thereto.

The thickness of each top plate body 3 is usually 0.5MM to 1.7MM but not limited thereto, and the total thickness of all top plate bodies 3 which are all attached to each other is smaller than the linear distance between two 'inner walls' of the cavity 1 outside the first and last top plate bodies 3 by a few tenths of millimeters, and the other two 'inner walls' of the cavity 1 are about 1MM from the outer edge of the adjacent top plate body 3.

Enough wide gaps are respectively reserved between the whole top plate body 3 and the inner walls of the four 'inner cavities 1', so that the 'every top plate body 3 which needs to move relatively to each other adjacently' can freely slide up and down without being blocked.

Each self-resetting elastic root 4 has a thickness no greater than that of the top plate body 3 above it, and the bottom end thereof is "planted" (i.e., inserted and fastened) on the bottom surface of the inner cavity 1 to prevent the whole elastic root from loosening from the resetting top plate 2.

Regardless of the shape, structure and material of the self-jacking resetting elastic root portion 4, the main functions are as follows:

the self-jacking reset elastic root 4 indirectly extruded by the top surface of the bolt head deforms downwards to store energy through manual operation, and automatically jacks up the top plate body 3 above the self-jacking reset elastic root by means of self elasticity after external force is removed until reset. (note: all the top edges of the top plate bodies 3 are flush with the opening edge of the wrench universal sleeve, and can be slightly non-flush if necessary.)

The adjacent self-jacking resilient roots 4 indirectly compressed by the top face of the bolt head are normally (but not exclusively) downwardly shortened by 5 to 13MM, and the particular top plate bodies 3 moving downwardly therewith are also now "downwardly concave" by 5 to 13 MM. In this way, a "rigid spanner clamp" consisting of "high, low and high" roof body 3 together, with an opening width exactly equal to the bolt head width and a depth of 5 to 13MM, appears on the top face of all roof bodies 3.

2. The universal sleeve for the wrench with the elastic root self-resetting top plate planted at the bottom of the inner cavity according to the technical scheme 1 is characterized in that,

each self-jacking resetting elastic root part 4 belongs to a letter C-shaped high-elasticity steel sheet, two ends of the self-jacking resetting elastic root part are welded on the extremely thin bottom surface of the specific top plate body 3, and the arc-shaped bottom is welded (or bonded) on the bottom surface of the inner cavity 1.

3. The universal sleeve for the wrench with the elastic root self-resetting top plate planted at the bottom of the inner cavity according to the technical scheme 1 is characterized in that,

the front surface and the back surface of each top plate body 3 comprise the anti-drag coating, so that the friction force of two adjacent top plate bodies 3 in relative sliding can be effectively reduced.

4. The universal sleeve for the wrench with the elastic root self-resetting top plate planted at the bottom of the inner cavity according to the technical scheme 1 is characterized in that,

for ease of understanding, the construction of the universal socket for wrenches is described in particular in terms of its manufacturing method as follows:

firstly, the left side edge of all the top plate bodies 3 is welded with the left wall of the inner cavity 1 into a whole.

And secondly, welding the right side edges of all the top plate bodies 3 and the right wall of the inner cavity 1 into a whole.

In a third step, a rectangular strip 5 is cut from the upper left corner of each top plate body 3 ".

In a fourth step, a rectangular strip 5 is cut from the upper right corner of each roof body 3 ".

Therefore, the overall shape of each top plate body 3 is changed from a rectangle to a Chinese character 'convex' shape, and the inner cavity 1 is also changed from a cuboid space to a Chinese character-like 'convex' shape space with the upper part being a smaller cuboid and the lower part being a larger cuboid.

At this time, "all the rectangular thin strips 5 welded to the left wall of the inner cavity 1" and "all the rectangular thin strips 5 welded to the right wall of the inner cavity 1" block the protruding portions on both sides of the bottom of each of the "convex" shaped top plate bodies 3 from coming off. In this way, the bottom end of the self-restoring elastic root portion 4 may not be fixed to the bottom surface of the cavity 1 (note: it may be fixed to the bottom surface of the cavity 1, of course).

Each of the self-jacking return elastic root portions 4 is a circular ring-shaped high-elasticity steel sheet, only the top end of which is fastened to the extremely thin bottom surface of the specific top plate body 3, and the rest of which is not fixed anywhere.

5. The universal sleeve for the wrench with the elastic root self-resetting top plate planted at the bottom of the inner cavity according to the technical scheme 4 is characterized in that,

6. The universal sleeve for the wrench with the elastic root self-resetting top plate is planted at the bottom of the inner cavity according to the

technical scheme

1 or 2 or 3 or 4 or 5, and is characterized in that,

the total thickness of all the top plate bodies 3 which are all tightly attached to each other is 30MM, and common micro and small bolts can be detached and installed respectively.

7. The universal sleeve for the wrench with the elastic root self-resetting top plate is planted at the bottom of the inner cavity according to the

technical scheme

1 or 2 or 3 or 4 or 5, and is characterized in that,

the total thickness of all the top plate bodies 3 which are all tightly attached to each other is 50MM, and common micro, small, medium and large bolts can be respectively assembled and disassembled.

8. The universal sleeve for the wrench with the elastic root self-resetting top plate is planted at the bottom of the inner cavity according to the

technical scheme

1 or 2 or 3 or 4 or 5, and is characterized in that,

the total thickness of all the top plate bodies 3 which are all tightly attached to each other is 128MM, and micro, small, medium, large and huge bolts can be respectively assembled and disassembled.

Second, the using method and the working principle of the utility model

1. Method of use and principle of operation of the utility model

A single sleeve cannot be used for dismounting the bolt, and a manual wrench handle or an electric wrench handle must be arranged. That is, the present invention belongs to only one structural component of a complete manual wrench (or a complete electric wrench), and the operation of the present invention is similar to the operation of a common manual wrench (or an electric wrench), specifically as follows:

before the universal sleeve for the wrench (namely the universal sleeve for the wrench) is pressed on the top surface of a bolt head to be screwed by a person, all the top edges with elastic roots, namely the top edges of the top plate body 3, of the self-reset top plate 2 are completely reset and are flush with the opening edge of the universal sleeve for the wrench, and a plane is formed together.

When a person presses the universal sleeve (namely the utility model) for the wrench on the top surface of the bolt head to be screwed, the self-jacking resetting elastic root part 4 indirectly extruded by the top surface of the bolt head shortens and deforms downwards and stores energy.

The adjacent self-jacking resilient roots 4 indirectly compressed by the top face of the bolt head are normally shortened downward by 5 to 13MM, and the specific roof body 3 moving downward together therewith is also "sunken downward" by 5 to 13 MM. In this way, a "rigid spanner clamp" consisting of "high, low and high three-fold" top plate bodies 3, the opening width of which is exactly equal to the bolt head width, will appear on the top surface of all the top plate bodies 3 in most cases.

At this time, the bolt can be screwed by operating the manual wrench handle (or the electric wrench handle).

Note that, in most cases, a "rigid wrench clamp" composed of "high, low, and high three-ply" roof body 3 is present on the top surface of all roof body 3. However, the roof plate bodies 3 from the first roof plate body to the Nth roof plate body are sunken downwards, and the rigid spanner clamp is formed by the 'two roof plate bodies 3' with one high and one low stack and the 'inner wall of the inner cavity 1 beside the low stack'.

In addition, sometimes all the top plate bodies 3 are recessed downward, and the rigid spanner clamp is formed by only two inner walls of the inner cavities 1 beside the first top plate body 3 and the last top plate body 3.

It can be seen that, as long as the width dimension of the bolt head to be screwed is not greater than the total thickness of the "full abutting elastic self-resetting top plate 2 (i.e. the full top plate body 3)", a "rigid spanner clamp" having an opening width just capable of clamping the bolt head can be formed regardless of the width dimension of the bolt head to be screwed. In this way, the wrench can adaptively grip bolt heads of various widths and sizes with the universal socket.

Obviously, after the wrench universal sleeve (i.e. the utility model) is pulled out of the bolt head by a hand, the top edges of all the self-reset top plates 2 with elastic roots (i.e. the top edges of the top plate bodies 3) automatically reset and are flush with the opening edges of the wrench universal sleeve, and a plane is formed together to prepare for next bolt screwing.

2. The utility model is in two cases of initially clamping the bolt head

"when the wrench is manually pressed by the universal socket (i.e. the utility model) on the top surface of the bolt head to be screwed", one of the following two situations may occur:

the first situation is as follows: the rigid spanner clamp is used for clamping two parallel opposite sides of a quadrangular bolt head, a hexagonal bolt head or an octagonal bolt head just, and at the moment, normal bolt screwing can be started until the end.

Case two: the rigid spanner clamp is used for clamping two opposite angles of a quadrangular bolt head, a hexagonal bolt head or an octagonal bolt head, and at the moment, normal bolt screwing can also be started.

However, after the clockwise (or anticlockwise) rotation is carried out for tens of degrees or twenty degrees or thirty degrees, one or more elastic self-reset top plates (2) at specific positions automatically push upwards and are inserted into new gaps formed just now, and the 'case two' is changed into the 'case one', so that the bolt screwing process is ensured to continue uninterruptedly until the end.

3. The utility model is suitable for bolts with different sizes

It is known that a common adjustable wrench adjusted by hand can be used for screwing bolts with small size or middle size or large size.

Similarly, if the size of the present invention is large enough, that is, the total thickness of all the top plate bodies 3 tightly attached to each other is large enough, for example, the total thickness is as high as 128MM, the present invention can separately assemble and disassemble micro, small, medium, large and huge bolts with different sizes.

From the above, the utility model has two advantages of 'only one sleeve can be used for respectively dismounting bolts with different sizes' and 'the bolt heads with different sizes can be clamped in a self-adaptive manner without manual adjustment'.

Detailed Description

The utility model discloses two embodiments in total, which are respectively explained as follows:

one, embodiment one

As shown in fig. 1, 2 and 3, the embodiment belongs to a universal sleeve for a wrench, the inner cavity of which is fully implanted with an elastic root self-resetting top plate, which is characterized in that,

the shape of the universal sleeve for the wrench is not limited.

Enough wide gaps are respectively reserved between the whole top plate body 3 and the inner walls of the four 'inner cavities 1', so that the 'every top plate body 3 which needs to move relatively adjacently' can freely slide up and down without being blocked.

The adjacent self-jacking resilient roots 4 indirectly compressed by the top face of the bolt head are normally (but not exclusively) downwardly shortened by 5 to 13MM, and the particular top plate bodies 3 moving downwardly therewith are also now "downwardly concave" by 5 to 13 MM. In this way, a "rigid spanner clamp" consisting of a "high, low, high" stack of roof bodies 3, the opening width of which is exactly equal to the bolt head width and the depth of which is 5 to 13MM, is present on the top face of all roof bodies 3.

In the first embodiment, each of the self-resetting elastic root portions 4 is a C-letter shaped high elastic steel sheet, both ends of which are welded to the extremely thin bottom surface of the specific top plate body 3, and the arc-shaped bottom is welded (or bonded) to the bottom surface of the inner cavity 1, as shown in fig. 3.

In the first embodiment, both front and back surfaces of each roof body 3 include the drag reduction coating, which can effectively reduce the friction force when two adjacent roof bodies 3 slide relatively.

In the first embodiment, the total thickness of all the top plate bodies 3 which are all tightly attached to each other is 30MM, and common micro and small bolts can be attached and detached, respectively.

Second, embodiment two

As shown in fig. 1, 2 and 4, the structure of the second embodiment is substantially the same as that of the first embodiment, except that,

firstly, the left side edges of all the top plate bodies 3 are welded with the left wall of the inner cavity 1 into a whole.

In a fourth step, a rectangular strip 5 is cut from the upper right corner of each top plate body 3 ".

In this way, the overall shape of each top plate body 3 is changed from a rectangle to a Chinese character ' convex ' shape, and the inner cavity 1 is also changed from a cuboid space to a Chinese character-like ' convex ' shape space with the upper part being a smaller cuboid and the lower part being a larger cuboid ', as shown in fig. 4.

At this time, "all the rectangular strips 5 welded to the left wall of the inner chamber 1" and "all the rectangular strips 5 welded to the right wall of the inner chamber 1" block the protruding portions on both sides of the bottom of each of the "convex" shaped top plate bodies 3 from coming out. In this way, the bottom end of the self-restoring elastic root portion 4 may not be fixed to the bottom surface of the cavity 1 (note: it may be fixed to the bottom surface of the cavity 1, of course).

In the second embodiment, each of the self-resetting elastic root portions 4 is a circular ring-shaped high-elasticity steel sheet, only the top end thereof is fastened to the extremely thin bottom surface of the specific top plate body 3, and the rest is not fixed anywhere, as shown in fig. 4.

In the second embodiment, the total thickness of all the top plate bodies 3 which are all tightly attached to each other is 128MM, and micro, small, medium, large and huge bolts can be attached and detached, respectively.

The above two embodiments are merely illustrative of the structure and operation of the present invention, and are not limited thereto. The technical solutions of the present invention are not limited to the above-mentioned embodiments, and the modifications and variations can be made without departing from the spirit and scope of the present invention.
