Abstract
It the utility model is related to a kind of locking device, including handle, compression bar, bearing, lock tongue, spring and closing piece；The lock tongue is two, and what is rotated is connected on bearing, and two lock tongues are oppositely arranged, and two opposite faces of lock tongue are inclined-plane, i.e. V-type slideway is formed between two lock tongues；Spring is used to provide spring force for two lock tongues so that two lock tongues are mutually drawn close；The closing piece is arranged in V-type slideway, and can be slided up and down in V-type slideway, open-top two lock tongues of spring force can be overcome when closing piece slides into V-type slideway lower part so that two lock tongues are opened and kept to both sides；Threaded hole is provided with bearing, and be located at compression bar thread fitting, compression bar lower end above closing piece, closing piece can be promoted to V-type slideway lower part when compression bar rotation moves down, when compression bar rotation moves up, closing piece can be moved up along V-type slideway under spring force, leave the latched position of V-type slideway lower part.The present apparatus is simple in structure, easy to operate, is easily used, and locking effect is good.
Description
Technical field
The utility model belongs to machine and adds field, is related to a kind of locking device.
Background technology
Since prong part is largely casting, during being finished to prong workpiece.Since cantilever is longer,
During being finished to cantilever, it may appear that prong chatter phenomenon during processing.Pitch at ear and send out in process in order to prevent
Raw chatter, devises a kind of clamping device for being used to prevent chatter at prong.
Utility model content
In view of the deficienciess of the prior art, the utility model proposes a kind of device clamped from part lower part.
Technical solution：A kind of locking device, including handle 1, compression bar 2, bearing 4, lock tongue 5, spring 6 and closing piece 7 are provided；
The lock tongue 5 is two, and what is rotated is connected on bearing, and two lock tongues are oppositely arranged, and two lock tongues are opposite
Face be inclined-plane, i.e. between two lock tongues form V-type slideway；
Spring is used to provide spring force for two lock tongues so that two lock tongues are mutually drawn close；
The closing piece is arranged in V-type slideway, and can be slided up and down in V-type slideway, is slided when closing piece slides into V-type
Spring force open-top two lock tongues can be overcome during road lower part so that two lock tongues are opened and kept to both sides；
Be provided with threaded hole on bearing 4, and with 2 thread fitting of compression bar, 2 lower end of compression bar is located above closing piece, when compression bar 2 rotates
Closing piece can be promoted to V-type slideway lower part when moving down, when the rotation of compression bar 2 moves up, closing piece can be under spring force along V
Type slideway moves up, and leaves the latched position of V-type slideway lower part.
Further, the closing piece is ball-type, back taper or inverted trapezoidal.
Further, it is inclined-plane on the inside of the lock tongue, outside is formed with fastener or hook part.
Further, both ends of the spring connects two lock tongues respectively.
Further, spring is two, is respectively that two lock tongues provide spring force.
Further, shaft 3 is additionally provided with, lock tongue is connected on bearing by what shaft rotated.
Technique effect：The present apparatus is simple in structure, easy to operate, is easily used, and locking effect is good.
Brief description of the drawings
Fig. 1 is the structure diagram of the present apparatus；
Wherein：Handle 1, compression bar 2, shaft 3, bearing 4, lock tongue 5, spring 6, closing piece 7.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of locking device, including handle 1, compression bar 2, bearing 4, lock tongue 5, spring 6 and closing piece 7 are provided；
The lock tongue 5 is two, and what is rotated is connected on bearing, and two lock tongues are oppositely arranged, and two lock tongues are opposite
Face be inclined-plane, i.e. between two lock tongues form V-type slideway；
Spring is used to provide spring force for two lock tongues so that two lock tongues are mutually drawn close；
The closing piece is arranged in V-type slideway, and can be slided up and down in V-type slideway, is slided when closing piece slides into V-type
Spring force open-top two lock tongues can be overcome during road lower part so that two lock tongues are opened and kept to both sides；
Be provided with threaded hole on bearing 4, and with 2 thread fitting of compression bar, 2 lower end of compression bar is located above closing piece, when compression bar 2 rotates
Closing piece can be promoted to V-type slideway lower part when moving down, when the rotation of compression bar 2 moves up, closing piece can be under spring force along V
Type slideway moves up, and leaves the latched position of V-type slideway lower part；The closing piece is ball-type；It is inclined-plane on the inside of the lock tongue, outside
Side is formed with fastener or hook part；Both ends of the spring connects two lock tongues respectively；Shaft 3 is additionally provided with, lock tongue is turned by shaft
Dynamic is connected on bearing.
