Description
Technical field
The utility model relates to a kind of wrench, particularly under a kind of small space, and special turning spanner easy to use.
Background technology
Now, the connection of parts uses bolted mode to realize in a large number, because assemble/disassemble is convenient.In order to pursue integrally-built miniaturization, the operating space holding spanner construction bolt is more and more less.
As: utility model patent: grid structure CN:203200923U discloses a kind of grid structure.Node and the chord member of this grid structure are bolted, and bolt is in node, and operating space is very little.Common right angle inner hexagon spanner, because force part is longer, each rotate very little angle after, force part is just stopped, needs common wrench to take out from bolt head, after reversely rotating angle, then puts into bolt head and installs or removes.This process is quite loaded down with trivial details, and has a large amount of nodes to need so to install in grid structure, wastes time and energy.
Although ratchet spanner can not repeat above-mentioned steps, can return by machine automatization, each limited angle rotated, back and forth carries out rotation and tightens operation, still quite loaded down with trivial details.In addition, the spanner that the size of the ratchet spanner of same size is more common is larger, and each rotatable angle is less.In the limiting case, the space of node may hold not bottom ratchet wheel spanner.
Utility model content
For above problem, the object of the utility model patent is to provide a kind of special turning spanner, to solve deficiency of the prior art.
The utility model provides a kind of special turning spanner, comprising: sleeve 10, rotating shaft 20 and at least one connector 30; Wherein, rotating shaft 20 is arranged in sleeve 10, and the top of rotating shaft 20 has rotating handles 21, and the bottom of rotating shaft 20 has at least one initiatively angular wheel 22; One end of connector 30 has driver bit 31, and the other end has driven angular wheel 32, and initiatively angular wheel 22 is meshed with driven angular wheel 32 one_to_one corresponding.
The utility model provides a kind of special turning spanner, can also have such feature: rotating shaft 20 and connector 30 are in 90 degree.
The utility model provides a kind of special turning spanner, can also have such feature: rotating shaft 20 and sleeve 10 are coaxially arranged.
The utility model provides a kind of special turning spanner, can also have such feature: the profile of sleeve 10 is hexagon.
The utility model provides a kind of special turning spanner, can also have such feature: driver bit 31 is hexagon socket head cap screw cutter head.
The beneficial effect of utility model
The special turning spanner of the one that the utility model provides, because, the angular wheel of rotating shaft engages with the angular wheel of connector, by the rotation of vertical direction rotating shaft, convert the rotation of horizontal direction connector to, power can be turned to like this, thus be transferred on bolt, not by the impact in space, bolt present position.
In addition, the one that the utility model provides special turning spanner can be tightened multiple bolt simultaneously, and in rundown process, the stressed of each bolt is in identical state, simplifies installation procedure, decreases the time of installation, improves installation effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the special turning spanner of embodiment one.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of the special turning spanner of embodiment two.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment one
Fig. 1 is the structural representation of the special turning spanner of embodiment one.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
As depicted in figs. 1 and 2, special turning spanner comprises: sleeve 10, rotating shaft 20 and connector 30.
Sleeve 10 is outer protective cover, is hollow structure, can hold rotating shaft 20 at internal rotating.The profile of sleeve 10 can be polygon, is preferably, grips time easy to use with hexagon, prevents from skidding.
Rotating shaft 20 is arranged in sleeve 10, and rotating shaft 20 and sleeve 10 are coaxial configuration.The top of rotating shaft 20 has rotating handles 21, for force when rotation.The bottom of rotating shaft 20 has initiatively angular wheel 22.
One end of connector 30 has driver bit 31.Driver bit 31 is hexagon socket head cap screw cutter head, also can be the driver bit of outer-hexagonal driver bit or other structure certainly as required.
Connector 30 other end has driven angular wheel 32, and initiatively angular wheel 22 is meshed with driven angular wheel 32.Rotating shaft 20 is 90 degree of angles with the central axis of connector 30.Certainly, need rotating shaft 20 and connector 30 according to practical application also can be other angle (as: 60 degree, 120 degree etc.), the demand of applicable different angles.
The special turning spanner course of work:
The node 200 of grid structure is connected with chord member by bolt 100.
Special turning spanner is put into node 200, in the end hexagon socket head cap screw cutter head 31 of connector 30 being aimed at bolt 100 in hexagonal.
Rotate the rotating handles 21 at rotating shaft 20 top, rotating shaft 20 rotates.Active angular wheel 22 bottom rotating shaft 20 rotates, and drive the driven angular wheel 32 be engaged with, the rotation of vertical direction rotating shaft 20, converts the rotation of horizontal direction connector 30 to.
The hexagon socket head cap screw cutter head of connector 30 rotates, and drives bolt 100 to rotate, is connected by node 200 with web member.
Demounting bolt 100, reversely rotates the rotary handle 21 of rotating shaft 20.
Embodiment two
Fig. 3 is the structural representation of the special turning spanner of embodiment two.
As shown in Figure 3, special turning spanner comprises: sleeve 10, rotating shaft 20 and two connectors 30.
The bottom of rotating shaft 20 has two initiatively angular wheels 22, has two connectors 30 to be engaged with connection respectively.Other modular construction is identical with embodiment one, no longer elaborates.
Certainly, the active angular wheel on rotating shaft and the quantity of connector can be more.Arrange like this to facilitate and disposable multiple bolts on same straight line to be tightened simultaneously.In actual installation, in order to force balance, a screw can be tightened in advance, but not exclusively tighten.Again another screw is also tightened in advance, finally again two screws are tightened respectively.
When to attachment force balance requirement height, may need repeated multiple timesly to tighten operation to screw respectively, guarantee multiple bolt strained balance.
The special turning spanner of embodiment two can be tightened multiple bolt simultaneously, and in rundown process, the stressed of each bolt is in identical state, simplifies installation procedure, decreases the time of installation, improves installation effectiveness.
