Abstract
The utility model relates to a drawer interlocking device for a switch cabinet, belonging to the technical field of accessories for low-voltage electric appliances. A drawer comprises a manual mechanism, a lock plate, a panel, a program lock and a push-in unit, wherein the push-in unit includes a handle hole, the manual mechanism is equipped with a manual connecting rod, the program lock is mounted on the panel and includes a swinging end, the lock plate includes a cooperation part, the manual connecting rod is controlled to push the lock plate to slide, the swinging end of the program lock is cooperated with the cooperation part of the lock plate, and the other end of the lock plate is inserted into the push-in unit and encloses the handle hole. The drawer interlocking device for the switch cabinet has the advantages that the lock plate is driven by the manual connecting rod, the swinging end of the lock plate is cooperated with the cooperation part, and the other end of the lock plate encloses the handle hole in the push-in unit, thereby locking the drawer; due to the fact that different drawers are simultaneously equipped with program locks with the same key, mechanical interlocking between at least two drawers can be realized; and thus, a low-voltage draw-out type switch cabinet can be more reliable in operation and safer in use.
Description
Technical field
The utility model belongs to low-voltage electrical apparatus attachment technique field, is specifically related to a kind of interlocking device for switchgear drawer.
Background technology
In low-voltage drawing switch apparatus, when two and above loop adopt breaker of plastic casing to be placed in same cabinet or different cabinet with drawer form, its interlocking form can only rely on electrical interlock at present, and though electrical interlock can prevent misoperation, but when electric loop breaks down, interlock can lose efficacy, thereby causes electric accident.Therefore, between drawer, in order to realize more reliable interlock, not only require to have electrical interlock, and require to have more reliable mechanical interlocking.Technical scheme described below produces based under above-mentioned background.
Summary of the invention
The purpose of this utility model is that a kind of interlocking device for switchgear drawer will be provided, it can be by least two drawers of inside switch cabinet, by operation, be arranged on the procedure lock on drawer, realize the interlocking between drawer, thereby greatly reduce low-voltage drawing switch apparatus because of the probability of electric fault misoperation generation accident, make low-voltage drawing switch apparatus move more reliable, safety.
The purpose of this utility model reaches like this, a kind of interlocking device for switchgear drawer, comprise drawer, be characterized in: described drawer comprises Shou Cao mechanism, jam plate, panel, procedure lock and propulsion plant, on described propulsion plant, there is handle hole, described Shou Cao mechanism is provided with hand behaviour connecting rod, on described panel, procedure lock is installed, on described procedure lock, there is a swinging end, on described jam plate, there is auxiliary section, by controlling the described jam plate of hand behaviour connecting rod promotion, slide, the swinging end of described procedure lock coordinates with the auxiliary section of described jam plate, the other end of jam plate probes in described propulsion plant, and realize the sealing to described handle hole by the described other end.
In a specific embodiment of the present utility model, described auxiliary section consists of the rectangular opening being opened on jam plate one end.
The utility model is owing to adopting said structure, the beneficial effect having: described jam plate is under hand behaviour connecting rod drives, swinging end on procedure lock coordinates with the auxiliary section of described jam plate, the other end by jam plate is realized the sealing to the handle hole on propulsion plant, thereby completes the lock operation to drawer; Meanwhile, because different drawers has been equipped with procedure lock simultaneously, and there is identical key, therefore can realize the mechanical interlocking between at least two drawers, make low-voltage drawing switch apparatus move more reliably, use safer.
Accompanying drawing explanation
Fig. 1 is an embodiment planar structure vertical view of the present utility model.
In figure: 1. drawer; 2.Shou Cao mechanism, 21. hand behaviour connecting rods; 3. jam plate ,31. auxiliary section, 32. other ends; 4. panel; 5. procedure lock, 51. swinging ends; 6. propulsion plant, 61. handle holes.
Embodiment
In order to make the public can fully understand technical spirit of the present utility model and beneficial effect; applicant will describe in detail embodiment of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, anyly according to the utility model design, changes in the form rather than substance all and should be considered as protection range of the present utility model.
Refer to Fig. 1, a kind of interlocking device for switchgear drawer of the utility model, comprises drawer 1, and described drawer 1 does not seal for body structure ，Qi top, and this drawer 1 comprises Shou Cao mechanism 2, jam plate 3, panel 4, procedure lock 5 and propulsion plant 6.Described Shou Cao mechanism 2 is positioned on drawer panel 4, described panel 4 is positioned at the front portion of drawer 1, in the face of operator, procedure lock 5 is installed on panel 4, on described procedure lock 5, there is a swinging end 51, be specially: swinging end 51 can be followed the folding of procedure lock 5 and be swung in certain angular range.Described propulsion plant 6 is arranged on drawer 1, on it, offer handle hole 61, after described handle hole 61 coordinates with operating grip, under the drive of handle hole 61Shou Cao mechanism 2, rotate, and drive propulsion plant 6 work, finally can drive described drawer 1 to enter or exit switch cubicle.Described Shou Cao mechanism 2 is provided with hand behaviour connecting rod 21, described jam plate 3 is generally a metal folding part, and there is an auxiliary section 31, and one end of jam plate 3 coordinates with hand behaviour connecting rod 21, and this kind of cooperation is intended to meet jam plate 3 and can under hand is grasped the rotation of connecting rod 21, horizontally slips; The other end 32 of jam plate 3 coordinates with handle hole 61, be specially: when jam plate 3 slides to the right under the rotation of hand behaviour connecting rod 21,31 lockings of swinging end 51Dui auxiliary section, the sealing being realized handle hole 61 by the other end 32 of jam plate 3, thereby make the operating grip cannot update hole 61, and then locked the turnover of drawer 1.
Due to the procedure lock 5 being positioned on different drawers 1, during as two drawers, share a key and (when three drawers, share two keys, when five drawers, share three keys, etc. forwards), thereby can guarantee, when key is opened procedure lock 5 on a drawer 1 wherein release propulsion plant 6, to be in the lock state with its other drawer 1 that shares this key.
The second optimization for the first above-mentioned embodiment is: described auxiliary section 31 consists of the rectangular opening being opened on jam plate 3 one end.To be swinging end 51 be positioned at rectangular opening on jam plate 3 by drive realizes coordinating of swinging end 51 and jam plate 3.This kind of optimization makes the simple in structure of auxiliary section 31, is convenient to processing.
