Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of structure is simple, the circuit breaker drawer frame of the short with locking mechanism low with production cost of manufacturing time.
For achieving the above object, the utility model provides following technical scheme: a kind of circuit breaker drawer frame of with locking mechanism, comprises drawer frame framework, and the inwall of described drawer frame framework is provided with drawer plate, described drawer plate is connected with the slippage of drawer frame framework, wherein:
Described drawer plate is provided with arm-tie and fixture block, described fixture block and drawer plate hinged, described fixture block take hinged place as one end, boundary is joint end, the other end is interlock end, the weight of described joint end is greater than the weight of interlock end, described joint end is provided with direction projection down, and described drawer frame framework is provided with the block be directed upwardly, and described projection coordinates clamping with block;
Described arm-tie is connected with drawer plate slippage, described arm-tie is provided with and the contact part of holding and coordinating of linking, and described contact part is held to conflict with interlock and linked.
By adopting technique scheme, fixture block utilizes gravity and drawer frame framework snap lock, when extracting arm-tie out, the linkage portion on fixture block is pushed in contact part on arm-tie, thus joint end is tilted, and unlocks arm-tie, make drawer plate can extract out from drawer frame framework, locking and the unblock of drawer plate can be realized without the need to the part such as back-moving spring, button, greatly simplify the structure of drawer frame, effectively reduce the process time of drawer frame, production cost.
The utility model is set to further: described drawer frame framework, drawer plate, fixture block offer through lock hole.
By adopting technique scheme, be located in lock hole by increasing securing rod, namely lockable locked drawer plate, prevents misoperation, simple and practical.
The utility model is set to further: be connected with back-moving spring between described arm-tie and drawer plate, and the direction of back-moving spring is identical with the moving direction of arm-tie.
By adopting technique scheme, to increase back-moving spring, slightly increasing the cost of the structure of some drawer frames, thus making drawer plate when without External Force Acting, can firmly be contracted in drawer frame.
The utility model is set to further: the hinged place of described fixture block and drawer plate is provided with torsion spring.
By adopt technique scheme, to increase back-moving spring, slightly increase the cost of the structure of some drawer frames, ensure fixture block effectively with the clamping of drawer frame framework, preventing fixture block because shaking unexpected dropout, greatly improving its security performance.

Embodiment
Shown in Fig. 5, a circuit breaker drawer frame for locking mechanism, comprises drawer frame framework 1, and the inwall of described drawer frame framework 1 is provided with drawer plate 2, described drawer plate 2 is connected by chute 13 slippage be arranged on drawer frame framework 1 sidewall with drawer frame framework 1, wherein particularly:
Described drawer plate 2 is provided with arm-tie 3 and fixture block 4, described fixture block 4 is hinged with drawer plate 2, described fixture block 4 take hinged place as one end, boundary is joint end 5, the other end is interlock end 6, the weight of described joint end 5 is greater than the weight of interlock end 6, described joint end 5 is provided with direction projection 7 down, described drawer frame framework 1 is provided with the block 8 be directed upwardly, and described protruding 7 coordinate clamping with block 8;
Described arm-tie 3 is connected with drawer plate 2 slippage, described arm-tie 3 is provided with the contact part 9 coordinated with the end 6 that links, conflict with interlock end 6 and link in described contact part 9, as shown in Figure of description 4, conflict with the interlock end 6 of fixture block 4 in contact part 9, keeps fixture block 4 to arrange in incline direction, thus make protruding 7 and block 8 clamping, if now pull drawer plate 2, then due to the locking between protruding 7 and block 8, drawer plate 2 cannot pull out; And for example shown in Figure of description 5, pull arm-tie 3, shown contact part 9 is first moved, interlock end 6 is pushed down in contact part 9, joint end 5 is tilted, thus shown fixture block 4 is separated with block 8, continue pull pulling block and then pull out shown drawer plate 2, realize locking and the unblock that can realize drawer plate 2 without the need to parts such as back-moving spring 11, buttons, greatly simplify the structure of drawer frame, effectively reduce the process time of drawer frame, production cost.
Further optimal design of the present utility model: described drawer frame framework 1, drawer plate 2, fixture block 4 offer through lock hole 10, be located in lock hole 10 by increasing securing rod, namely lockable locked drawer plate 2, prevents misoperation, simple and practical.
Due in the course of processing, better in order to ensure the result of use of described circuit breaker drawer frame, back-moving spring 11 is increased between described arm-tie 3 and drawer plate 2, the direction of back-moving spring 11 is identical with the moving direction of arm-tie 3, described fixture block 4 is provided with torsion spring 12 with the hinged place of drawer plate 2, compared with said structure, this structure still eliminates the parts such as button, and only to increase back-moving spring 11, slightly increase the cost of the structure of some drawer frames, thus make drawer plate 2 when without External Force Acting, can firmly be contracted in drawer frame; In the same manner, to increase back-moving spring 11, slightly increase the cost of the structure of some drawer frames, ensure fixture block 4 effectively with drawer frame framework 1 clamping, preventing fixture block 4 because shaking unexpected dropout, greatly improving its security performance.
