Description
Technical field
The utility model relates to the instrument cell-type casing technical field of power system High-low voltage switch cabinet, relates in particular to a kind of switching mechanism of chamber door.
Background technology
In the use of High-low voltage switch cabinet, control room's casing often need to open and close operation, to carry out equipment installation and measuring maintenance and electric operation, in assembling, maintenance and debug process, also needs chamber door to carry out opening and closing operations.Along with the variation of product design, complete function, the differentiation of operation tool, especially require more and more higher to the working service of product, cost to production debugging maintenance and efficiency require also improving, and therefore the switching mechanism of chamber door should be convenient to the operation such as observation, installation, maintenance, dismounting of box house, simultaneously should be time saving and energy saving, cost is low, and efficiency is high.A) existing chamber door can be supported on a fixing angle after normally opening, and is 75 ° substantially.And the use scene of product has diversity, detect maintenance condition and there is complexity, the angle that chamber door is opened is unique and fixing, may affect the use of instrument, be unfavorable for execute-in-place, sometimes even lay down chamber door and just can operate, greatly reduce operating efficiency, increase maintenance cost, affected the use of product.Although b) assist or adopt the modes such as auxiliary support bar by increase personnel, can realize chamber door multi-angle opens, but the scene using due to product has limitation, also can increase operating time and cost, be difficult for realizing the necessary low cost of detection maintenance of electric power system, high efficiency requirement.Traditional chamber door can only be supported on unique fixing angle after opening, and in real work, due to the difference of product structure and applicable situation, the angle that chamber door is opened requires also different.In engineering practice, can there is the operations such as some installation, maintenances, chamber door need to be opened to different angles and can be supported fixing.By existing door opening or closing structure, angle cannot support fixing after changing, and just need to increase personnel coordinate or chamber door is laid down, and can cause damage to product, has also increased cost and operating time, has affected operating efficiency.
Utility model content
The utility model object is exactly the defect in order to make up prior art, and a kind of switching mechanism of chamber door is provided.
The utility model is achieved through the following technical solutions:
A kind of switching mechanism of chamber door, include casing, above casing, be provided with chamber door, described chamber door and casing are connected through the hinge, inwall left and right sides at chamber door is respectively equipped with box door lock, below box door lock, be fixed with respectively support bar axle, one end of support bar is connected with support bar axle, inner side at the side plate being connected with chamber door of casing is provided with fixed mount, left and right sides at fixed mount all has corresponding with box door lock and support bar respectively square hole, is provided with multiple steps that block the square hole corresponding with support bar at the lateral surface of support bar.
Step on described support bar is 4, the long 3cm of each step.
The utility model has the advantages that: the utility model door opening and closing mechanism reliable lock, in the time opening, can carry out multi-angle selection, there is strong adaptability, use the features such as simple, convenient, efficient, can well solve the installation, detection or the maintenance difficult that cause because of the restriction of the condition such as instrument or operating personnel job site, greatly having improved installation effectiveness, is a kind of comparatively desirable door opening and closing mechanism.

Detailed description of the invention
As shown in Figure 1, a kind of switching mechanism of chamber door, include casing 6, above casing 6, be provided with chamber door 1, described chamber door 1 is connected by hinge 7 with casing 6, inwall left and right sides at chamber door 1 is respectively equipped with box door lock 2, below box door lock 2, be fixed with respectively support bar axle 3, one end of support bar 4 is connected with support bar axle 3, inner side at the side plate being connected with chamber door 1 of casing 6 is provided with fixed mount 5, all have corresponding with box door lock 2 and support bar 4 respectively square hole at the left and right sides of fixed mount 5, be provided with multiple steps 8 that block the square hole corresponding with support bar 4 at the lateral surface of support bar 4.
Step on described support bar is 4, the long 3cm of each step.
After chamber door 1 is closed, box door lock 2 rotation lock tonguings enter in the square hole with fixed mount 5, have realized the close locking of chamber door 1 with casing 6.
When chamber door 1 is opened, support bar 4 rotates and stretches out with chamber door around support bar axle 3 under Action of Gravity Field, and by Fig. 2 structure, in the time that open angle reaches 75 °, support bar downside step can be stuck in fixed mount square hole place, realizes 75 ° of chamber doors and opens and support fixing.
As increased by 4 ledge structures in Fig. 3 in end, between each ledge structure, be of a size of 3mm, length suitably increases simultaneously.Chamber door is opened in operation, and 4 ledge structures support respectively to be fixed, and can realize chamber door open angle and be respectively 60 °, 75 °, 90 °, 105 °, as shown in Figure 4.
While being greater than 90 ° due to chamber door open angle, casing front exposes completely, can not be subject to the impact of chamber door to the operation such as installation, inspection and repair of box house, though opening larger angle is not difficult to realize, but practical significance declines, when particular/special requirement, also can realize more opening of wide-angle of chamber door.
