Abstract
The utility model provides a spinning lock, which mainly solves the problem that for the existing spinning lock, clamping force between a steel ball and a steel wire is poor, so that the steel wire can not be tightly clamped or is easy to fall off. The spinning lock is characterized in that one-way locking holes (3) comprise a straight hole (31), a tapered hole (32) and an arc (33) which are arranged from outside to inside in sequence, wherein the diameter of the straight hole (31) is 6-9 mm; and the cone angle of the tapered hole (12) is 12-19 degrees. According to the spinning lock, the structure of a lock body is improved; and the spinning lock has the advantages of flexibility in operation, large locking force, and safety and reliability.
Description
Technical field
The utility model relates to a kind of lockset, is specifically related to a kind of lock that reels off raw silk from cocoons.
Background technology
The lock that reels off raw silk from cocoons is also claimed sealing lock, is widely used in industries such as railway, highway, harbour, electric industry, postal service, like the cargo container in the railway transportation, the postal object of posting etc.The existing lock that reels off raw silk from cocoons mainly is made up of lock body and steel wire, and lock body is provided with the one-way locking passage that steel wire penetrates, and an end and the lock body of steel wire are fixed; The other end of steel wire penetrates the locking passage; Behind the taut wire, steel wire can not be return, need be with cutting pliers with steel wire shearing when release.Gauge of wire is generally 1.6～2.0mm, and the locking passage is divided into steel wire and penetrates hole and one-way locking hole, and spring and steel ball are installed in the one-way locking hole, realizes one-way locking through spring and steel ball.The one-way locking hole is followed successively by straight hole, conical bore and circular arc from outside to inside; Steel ball is positioned at arc section, owing to can not reach best cooperation between the coning angle of conical bore and the steel ball, and in use; Clamping force is poor between steel ball and the steel wire, causes the not tight or caducous phenomenon of steel wire card.
The utility model content
Poor in order to solve the existing clamping force that reels off raw silk from cocoons between lock steel ball and the steel wire; Cause the not tight or caducous problem of steel wire card; The utility model provides a kind of lock that reels off raw silk from cocoons, and this lock that reels off raw silk from cocoons has improved the structure of lock body, has flexible operation, clamping force and reaches safe and reliable characteristics greatly.
The technical scheme of the utility model is: a kind of lock that reels off raw silk from cocoons comprises lock body and steel wire; Lock body is provided with the one-way locking hole that steel wire penetrates, and an end and the lock body of steel wire are fixed, and the other end of steel wire passes the one-way locking hole; Be provided with steel ball, spring and end socket in the one-way locking hole; The one-way locking hole is divided into straight hole, conical bore and circular arc from outside to inside successively, and straight hole diameter wherein is 6～9mm, and the coning angle of conical bore is 12 °～19 °.
Straight hole diameter in the described one-way locking hole is 7mm.
The coning angle of the conical bore in the described one-way locking hole is 14 °.
The utlity model has following beneficial effect: owing to take such scheme, in use, steel wire passes the one-way locking hole, the pull steel wire; Spring is compressed, and steel ball gets into conical bore, stops drag steel wire; Steel ball gets into circular arc and blocks mutually with steel wire under the effect of spring force, the coning angle of conical bore can make steel ball successfully enter in the circular arc, has reached best cooperation between the coning angle of conical bore and the steel ball; Clamping force between steel ball and the steel wire is big, and is safe and reliable, flexible operation.
Description of drawings
Accompanying drawing 1 is the structure sectional view of the utility model.
1-lock body among the figure, 2-steel wire, 3-one-way locking hole, 31-straight hole, 32-conical bore, 33-circular arc, 4-steel ball, 5-spring, 6-end socket, 7-shell.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; A kind of lock that reels off raw silk from cocoons comprises lock body 1 and steel wire 2, and lock body 1 is provided with the one-way locking hole 3 that steel wire 2 penetrates, and an end of steel wire 2 and lock body 1 are fixing; The other end of steel wire 2 passes one-way locking hole 3; Be provided with steel ball 4, spring 5 and end socket 6 in the one-way locking hole 3, steel ball 4 is three, the lock body 1 outer shell 7 that is injected with.One-way locking hole 3 is divided into straight hole 31, conical bore 32 and circular arc 33 from outside to inside successively, and straight hole 31 diameters wherein are 6～9mm, and the coning angle of conical bore 32 is 12 °～19 °.Owing to take technique scheme, in use, steel wire 2 passes one-way locking hole 3, pull steel wire 2; Spring 5 is compressed, and steel ball 4 gets into conical bore 32, stops drag steel wire 2; Steel ball 4 gets into circular arc 33 and blocks mutually with steel wire 2 under the effect of spring 5 elastic force, the coning angle of conical bore 32 can make steel ball 4 successfully enter in the circular arc 33, has reached best cooperation between the coning angle of conical bore 32 and the steel ball 32; Clamping force between steel ball 4 and the steel wire 2 is big, safe and reliable, flexible operation.
The coning angle of the conical bore 32 in the described one-way locking hole 3 is 14 °.Present embodiment is an optimal way, but ought also can choose other numerical value in the above-mentioned value range.
