Abstract
This utility model relates to a kind of self-locking activity teeth spanner, it is made up of quiet chuck, dynamic chuck, set screw and handle, in the cubic through hole that quiet chuck is made, set screw is installed, helical teeth it is shaped with in set screw, this helical teeth outer straight tooth row made with dynamic chuck is meshed, and is co-axially mounted a spring on the set screw axle of set screw lower end.This spanner is co-axially mounted a spring on the set screw axle of set screw lower end, the quiet chuck of aperture position is shaped with teeth, the spring installed can make set screw have displacement in the axial direction, thus can make the most still to have between the opening of chuck and quiet chuck displacement, i.e. after set screw positions, dynamic chuck can overcome spring force, expands certain aperture displacement amount, so ensure to reach bottom limit position when opening turns nut, it is ensured that agreeing with completely of setting-in.
Description
Technical field
This utility model belongs to machining tools art, relates to locking tool adjustable wrench, especially a kind of self-locking movable teeth
Tooth spanner.
Background technology
The locking tool that spanner is machinery industry and building trade commonly uses, is divided into fork spanner and adjustable wrench.Stay and pull
The nut of single bore is only locked by hands, and adjustable wrench is called for short adjustable wrench, and its A/F can regulate within the specific limits,
It is used to a kind of instrument of the nuts and bolt of fastening and a pine different size.Adjustable wrench tighten or rise pine nut time,
Owing to the screw thread that dynamic chuck is made is straight-tooth, the made tooth of set screw is helical teeth, and therefore during the two engagement, gap therebetween is relatively
Greatly, cause quiet chuck and dynamic chuck to have certain string quantity, when using spanner, occur that opening diameter loosens the situation of change, cause behaviour
Workmanship needs to use finger to pin set screw, can realize fastening smoothly and playing pine, thus cause work efficiency relatively low.
By retrieval, find that the patent document relevant to this utility model application has following three:
1, a kind of wedge block self-locking monkey wrench (CN201524977U), is made up of quiet chuck, dynamic chuck, actuator, handle.Dynamic
Having wedge hole at chuck patch handle, wedge sets voussoir in hole；Actuator is by pushing block, spring, slide opening, slide cartridge, slide bar, button, cone
Cylinder, lock pin, hole, T-shaped pin, lever, guide rail, slide bar connect composition.It is widely used in machine-building, the nut screwing clamping of repairing, pine
Open.
2, a kind of cone self-locking adjustable spanner (CN201579725U), is made up of quiet chuck, dynamic chuck, actuator, handle.Institute
The actuator stated moves chuck patch left handle and has bellmouth, is provided with cone in hole, and the actuator of cone left end is provided with button,
Spring one end connects in the middle part of cone, and on other end connecting handle, cone right part is provided with gear, and the handle answered with gear mesh is provided with tooth
Bar.It is widely used in the tightening of the nut mechanically of industry, building, agricultural, sphere of life, unclamps.
3, a kind of helical tooth self-locking adjustable wrench (CN201544158U), is made up of quiet chuck, dynamic chuck, actuator, handle.Adjust
Joint device is that chuck right lower quadrant is provided with helical teeth, and on quiet chuck right lower quadrant, fixing connection guide-rail plate, is provided with in guide-rail plate and its shape
The corresponding slide plate of shape, size, is provided with helical teeth below slide plate right part.It is widely used in industry, building, agricultural, forestry, life etc.
Every field machinery, the nut screwing clamping of equipment and unclamping.
Patent documentation disclosed above, although goal of the invention is similar with this utility model application, but equal in terms of technical scheme
Differ, do not interfere with the creativeness of this utility model application.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of design science, be skillfully constructed
Self-locking activity teeth spanner.
This utility model solves technical problem and be the technical scheme is that
A kind of self-locking activity teeth spanner, is made up of quiet chuck, dynamic chuck, set screw and handle, quiet chuck and handle
Integrally making, in quiet chuck, upper and lower gap is provided with dynamic chuck, and this dynamic chuck is shaped with outer straight tooth row in quiet chuck, at quiet folder
In made cubic through hole, set screw is installed, set screw is shaped with helical teeth, this helical teeth made with dynamic chuck outer directly
Tooth row is meshed, it is characterised in that: on the set screw axle of set screw lower end, it is co-axially mounted a spring.
And, the quiet chuck quiet chuck with dynamic chuck aperture position is shaped with teeth.
Advantage of the present utility model and good effect be:
1, this spanner is co-axially mounted a spring on the set screw axle of set screw lower end, at the quiet chuck of aperture position
On be shaped with teeth, the spring installed can make set screw have displacement in the axial direction, thus can make opening of chuck and quiet chuck
The most still having displacement between Kou, i.e. after set screw positions, dynamic chuck can overcome spring force, expands certain
Aperture displacement amount, so ensures to reach bottom limit position when opening turns nut, it is ensured that agreeing with completely of setting-in.
2, this spanner can agree with after nut at opening, when handle turns nut downwards completely in the teeth that quiet chuck is made
Teeth are snapped on nut, and now spanner can realize again the function of pipe wrench.
3, this spanner is skillfully constructed, simple in construction, and processing ease is with low cost, has two merits of adjustable wrench and pipe wrench
Can, it is effectively increased the work efficiency of operative employee.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is the close-up schematic view of Fig. 1.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are simply retouched
The property stated, be not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of self-locking activity teeth spanner, is made up of quiet chuck 3, dynamic chuck 5, set screw 2 and handle 1, quiet chuck with
Handle is integrally made, and in quiet chuck, upper and lower gap is provided with dynamic chuck, and this dynamic chuck is shaped with outer straight tooth row 7 in quiet chuck；
Being provided with set screw in the cubic through hole that quiet chuck is made, set screw is shaped with helical teeth, this helical teeth is made with dynamic chuck
Outer straight tooth row be meshed.
Innovative point of the present utility model is:
The set screw axle of set screw lower end is co-axially mounted a spring 6, the quiet chuck of aperture position is shaped with
Teeth 4.The spring installed can make set screw have displacement in the axial direction, thus can make between the opening of chuck and quiet chuck
The most still having displacement, i.e. after set screw positions, dynamic chuck can overcome spring force, expands certain opening position
Shifting amount, so ensures to reach bottom limit position when opening turns nut, it is ensured that agreeing with completely of setting-in.The tooth that quiet chuck is made
Tooth can agree with after nut completely at opening, and when handle turns downwards nut, teeth are snapped on nut, and now spanner is the most permissible
Realize the function of pipe wrench.
