Abstract
The invention discloses a compression plate locking mechanism for a breast X ray machine. The Compression plate locking mechanism comprises a locking shaft and a locking handle. The locking shaft is combined on compression plate of the X ray machine in horizontal direction and with a right guide pin, a position limiting mechanism, a compression plate pin and the locking handle in order. One end of the middle section of the locking shaft is provided with a circular arc shaped eccentric groove at a position matching with the compression plate pin. For the design of the eccentric groove, when the locking handle is rotated, the locking shaft rotates accordingly to realize interference fit and clearance fit, further achieving the locking and position limiting function. With the invention, problems of impossibility to change the compression plate or to remove horizontal gap of a locking mechanism can be solved. This also makes an opposing plate easy to change.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of breast X-ray machine press discs lockable mechanism.
Background technology
Breast X-ray machine operationally press discs will bear the pressure of about 300N and press discs can not loosen, consideration simultaneously for aspects such as health needs regular replacing press discs, therefore breast X-ray machine need possess a kind of retaining mechanism, press discs can be locked when press discs works, and for convenience detach when changing press discs.Because of manufacture accuracy and matching problem, reliability is not high mostly for the breast X-ray machine of domestic production, does not generally change press discs; As shown in Figure 3, external product is by stopping means roller, and in the vertical direction bestows load to press discs latch, locks the object of press discs when reaching in working order; Need a hands pressing locking button during this type of replacement of products press discs, promote connected roller and move on preset track, force roller to be separated with press discs latch, thus make press discs can be disassembled lower replacing.This type of lockable mechanism cannot eliminate the gap of locking shaft horizontal direction, and inconvenient skilled worker changes press discs.
Summary of the invention
Cannot change for solving existing breast X-ray machine press discs, inconvenient during replacing, lockable mechanism cannot the problem in gap, elimination of level direction, the invention provides a kind of structure simple, the breast X-ray machine press discs lockable mechanism that the good reliability of result of use is high.
The present invention adopts following technical scheme to realize: a kind of breast X-ray machine press discs lockable mechanism, comprises locking shaft 1, locking handle 3.It also comprises position-limit mechanism 4, keeper.The eccentric grove 5 of one circular arc is had in the middle of locking shaft 1.Locking shaft tail end stopping means 4 is that spring steel ball is spacing, and steel ball vertical direction touches with locking shaft and spring interface respectively, and locking shaft tail end face is connected and fixed the position of locking shaft 1 by pilot pin and press discs support.Rotate clockwise locking handle 3 to lock position, locking shaft 1 is rotated thereupon, eccentric grove 5 combines with press discs latch 2, now locking shaft 1 and press discs latch 2 interference fit, steel ball is by the groove that heads in locking shaft 1 under the thrust of spring, and the load of vertical direction bestowed by locking shaft 1 pair of press discs latch 2, and press discs 6 is locked, cannot loosen, press discs 6 steady operation.Rotate counterclockwise locking handle 3 to restraining position, locking shaft 1 is rotated thereupon, eccentric grove 5 and press discs latch 2 are separated, now matched in clearance between locking shaft 1 and press discs latch 2, steel ball directly acts on locking shaft 1 under spring thrust effect, the load that vertical direction granted by locking shaft 1 pair of press discs latch 2 reduces greatly, and press discs 6 can be dismantled at this moment or load, and skilled worker's one-handed performance can change press discs easily.
Beneficial effect of the present invention is: lockable mechanism only need rotate locking handle can complete locking and limit function, lockable mechanism is locked press discs when breast X-ray machine press discs works, make its steady operation, when needing to change press discs simultaneously, only need rotate locking handle, skilled worker's one-handed performance, changes press discs very convenient.The existence of pilot pin simultaneously eliminates lockable mechanism horizontal clearance, and spring steel ball position-limit mechanism can allow user obtain better feel when operating and provide the signal that puts in place, and this invention breast X-ray machine press discs lockable mechanism working stability, reliability is high.

Detailed description of the invention
A kind of breast X-ray machine press discs lockable mechanism, comprises locking shaft 1, locking handle 3.It also comprises position-limit mechanism 4, keeper.The eccentric grove of one circular arc is had in the middle of locking shaft 1.Locking shaft tail end is spacing fill 4 for spring steel ball spacing, steel ball vertical direction touches with locking shaft and spring interface respectively, and locking shaft tail end face is connected and fixed the position of locking shaft 1 by pilot pin and press discs support.Rotate clockwise locking handle 3 to lock position, locking shaft 1 is rotated thereupon, eccentric grove 5 combines with press discs latch 2, now locking shaft 1 and press discs latch 2 interference fit, steel ball is by the groove that heads in locking shaft 1 under the thrust of spring, and the load of vertical direction bestowed by locking shaft 1 pair of press discs latch 2, and press discs 6 is locked, cannot loosen, press discs 6 steady operation.Rotate counterclockwise locking handle 3 to restraining position, locking shaft 1 is rotated thereupon, eccentric grove 5 and press discs latch 2 are separated, now matched in clearance between locking shaft 1 and press discs latch 2, steel ball directly acts on locking shaft 1 under spring thrust effect, the load that vertical direction granted by locking shaft 1 pair of press discs latch 2 reduces greatly, and press discs 6 can be dismantled at this moment or load, and skilled worker's one-handed performance can change press discs 6 easily.
