Position, with locking wrench body 11.
Spanner locking mechanism of the present utility model is used for the connection locking of veneer and subrack, refer to Fig. 1-Fig. 4, spanner lock
Determine mechanism include wrench body 11, spanner bearing 12 and locking external member 13, wrench body 11 respectively with spanner bearing 12, locking
External member 13 is flexibly connected.Specifically, wrench body 11 includes connects bearing 110, has external part 111, spanner in connects bearing 110
Bearing 12 includes bayonet part 122, and bayonet part 122 is hollow U-shaped structure, there is the logical of cooperation on external part 111 and U-shaped structure
Hole, external part 111 put in the hollow position of U-shaped structure, and through hole is passed through by external part 111 and bayonet part by the first rotary shaft
122 connections, so as to realize the connection of spanner bearing 12 and wrench body 11, during wherein wrench body 11 is with first rotating shaft 112
The heart rotates around spanner bearing 12.Also include the first perforate 113 in connects bearing 110, for accommodating the position restrainer of locking external member 13
Structure 133, through hole is provided with position-limit mechanism 133, is extended with the second rotating shaft 114 in the first perforate 113, on position-limit mechanism 133
Through hole passes through through hole, in realizing that the connection of position-limit mechanism 133 and connects bearing 110, position-limit mechanism 133 are with the second rotating shaft 114
The heart rotates around connects bearing 110.Locking external member 13 has locking and opens two states, when locked, wrench body 11 and spanner
Bearing 12 is locked；When activated, wrench body 11 can rotate around spanner bearing 12, pass through the bayonet socket knot in wrench body 11
Structure, realize the plug of veneer.Specifically, only lock spacing bayonet 121 is provided with spanner bearing 12, when wrench body 11 is movable,
The position-limit mechanism 133 of locking external member 13 is driven to move, when position-limit mechanism 133 moves to the only lock spacing bayonet with spanner bearing 12
During 121 contact, only lock spacing bayonet 121 is spacing to position-limit mechanism 133, and locking external member 13 can not be moved further, realize spanner
The locking of locking mechanism.
Further, the locking external member 13 also includes unlocking mechanism 131, and the connects bearing 110 includes accommodating institute
State the second perforate 115 of unlocking mechanism 131.
Locking external member 13 of the present utility model also includes unlocking mechanism 131, and unlocking mechanism 131 is used for spanner locking mechanism
Locking or unblock operation, the second perforate 115 for accommodating this unlocking mechanism 131 is provided with connects bearing 110.Unlocking mechanism
131 can be wedge type block, and corresponding second perforate 115 is wedge groove, to be assembled with wedge type block.Second perforate 115 and first
Perforate 113 connects, so that the unlocking mechanism 131 positioned at the second perforate 115 and the position-limit mechanism 133 positioned at the first perforate 113
Contact, unlocking mechanism 131 is received into locking or unblock operation is delivered to position-limit mechanism 133, position-limit mechanism 133 is rotated, enters
And position-limit mechanism 133 is deviate from or is locked from only lock spacing bayonet 121, realize the locking or unblock of spanner locking mechanism.
In further technical scheme, the unlocking mechanism 131 and position-limit mechanism 133 are pinion and rack, its
Middle unlocking mechanism 131 is rack, and position-limit mechanism 133 is gear, and the linear motion of unlocking mechanism 131 is converted into position-limit mechanism
133 rotation.
In order to which the locking or unblock operation that receive unlocking mechanism 131 are delivered to position-limit mechanism 133, the present embodiment will solve
Latch mechanism 131 is set as pinion and rack with position-limit mechanism 133, and unlocking mechanism 131 is rack, and position-limit mechanism 133 is tooth
Wheel, the unlocking mechanism 131 as rack moves along a straight line under unblock or locking action power, by the position-limit mechanism for being used as gear
133 are converted to rotation.Specifically, unlocking mechanism 131 is provided with conversion surface 132, and conversion surface 132 coordinates with position-limit mechanism 133, will
Linear motion caused by unblock operation forces is converted to the rotary motion of position-limit mechanism 133.Conversion surface 132 is unlocking mechanism
131 plane or contacted with each other with unlocking mechanism 131, the unblock of unlocking mechanism 131 can be operated transmit it is another
A plane on one part.When conversion surface 132 is a plane of unlocking mechanism 131, the unblock unblock behaviour of unlocking mechanism 131
The plane of work and conversion surface 132 are orthogonal, and conversion surface 132 contacts with position-limit mechanism 133, to transmit unlocking mechanism 131
Locking or unblock operation.When conversion surface 132 is a plane on another part, unlocking mechanism 131 is led to this another part
The connection of the elastic components such as spring is crossed, realize the unlocking function of unlocking mechanism 131 is a plane in unlocking mechanism 131, realizes and turns
Change function is a plane on another part, and the plane in this unlocking mechanism 131 and the plane on this another part are mutual
It is perpendicular.
Spacing bayonet 121 is only locked to the spacing of position-limit mechanism 133 in order to realize, position-limit mechanism 133 is shaped to
Cam wheel, and using the face contacted on this cam wheel with the conversion surface 132 of unlocking mechanism 131 as contact surface 136, contact surface
Multiple second teeth 135 are provided with 136, multiple first teeth 134, the first tooth 134 and the second tooth 135 are provided with conversion surface 132
Engagement, realizes that the linear motion of unlocking mechanism 131 is converted to the rotation of position-limit mechanism 133.When needing to lock or unlocking, user
Locking or unblock operation are made to unlocking mechanism 131, when unlocking mechanism 131 receives this locking or unblock operation, passes through conversion
Face 132 drives position-limit mechanism 133 to move.Because of the active force that unblock operation applies for user, this active force drives conversion surface 132 to exist
Moved back and forth in second perforate 115, unlocking mechanism 131 with the contact surface 136 of position-limit mechanism 133 by driving position-limit mechanism 133
Rotate, so that position-limit mechanism 133 is deviate from, spacing bayonet 121 is only locked in clamping, or position-limit mechanism 133 is opened in abjection, clamping,
And then realize the locking or unblock of spanner locking mechanism.Further, only lock spacing bayonet 121 is located at bayonet part 122, and is located at
In the rotary motion trace of position-limit mechanism 133, while the lug boss 137 of raised gear rotates towards bayonet part 122, position-limit mechanism 133
When, the lug boss 137 of raised gear rotates towards bayonet part 122, when turning to spacing only position where pintle hook lock mouth, raised tooth
Wheel is spacing by only lock spacing bayonet 121, the locking of spanner locking mechanism.Now apply unblock operation to unlocking mechanism 131, make spacing
Mechanism 133 deviates from from only lock spacing bayonet 121, applies the active force away from only lock position-limit mechanism 133 direction to wrench body 11,
Wrench body 11 drives locking external member 13 to be moved to away from only lock position-limit mechanism 133 direction, unlocks spanner locking mechanism, will be single
Plate takes out from subrack.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure transformation under design of the present utility model, made using the utility model specification and accompanying drawing content, or
Directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
