Description
Technical Field
The utility model relates to a cubical switchboard valve mechanism, concretely relates to integral type valve mechanism of cubical switchboard.
Background
The switch cabinet valve mechanism is an important component of the switch cabinet. The function is as follows: when the handcart is pushed into a handcart room, the upper valve and the lower valve are opened through the valve mechanism of the switch cabinet, so that the contact arm on the handcart can be inserted into the stationary contact seat behind the valve; when the handcart is pulled out of the handcart room, the upper valve and the lower valve are closed by the valve opening and closing mechanism so as to shield the stationary contact seat behind the valve. The existing valve mechanism is unreasonable in structural design, and the contact area between the roller on the unlocking rod of the valve mechanism and the handcart is small, so that the transmission between the handcart and the unlocking rod is not flexible enough, and the valve mechanism is low in reliability and has the defects of unreliable performance and short service life.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, performance safe and reliable, simple operation, long service life's integral type valve mechanism.
In order to achieve the purpose, the utility model adopts an integrated valve mechanism, which comprises a mechanism frame, an unlocking transmission component arranged on the mechanism frame, an upper valve and a lower valve, the unlocking transmission component comprises a first unlocking crank arm rotationally arranged on the framework, a first torsion spring arranged between the first unlocking crank arm and the mechanism frame, a second unlocking crank arm rotationally arranged on the framework, a second torsion spring arranged between the framework and the second unlocking crank arm, an upper connecting rod connected between the upper valve and the first unlocking crank arm, and a lower connecting rod connected between the lower valve and the second unlocking crank arm, one of first unblock connecting lever, second unblock connecting lever serve and all be provided with a gag lever post, each gag lever post on all the activity be provided with handcart matched with first pulley, second pulley, first pulley, second pulley set up on the gag lever post side by side.
The beneficial effect of above-mentioned structure is: two pulleys matched with the handcart are arranged on the limiting rods of the first unlocking connecting lever and the second unlocking connecting lever, so that the contact area between the pulleys and the handcart is increased, the handcart and the pulleys are prevented from being jammed, and the handcart, the first unlocking connecting lever and the second unlocking connecting lever are more flexibly and reliably transmitted. Therefore, the reliability of the work of the unlocking transmission assembly is improved, and the valve mechanism has the advantages of simple structure, safe and reliable performance, convenience in operation and long service life.
Particularly, the framework formula structure as an organic whole, and be provided with the pivot on the framework, the one end of first unblock turning arm, second unblock turning arm rotate and set up in the pivot, and be provided with a hangers portion that is connected with first torsional spring, second torsional spring on the framework respectively. The mechanism frame adopts the integral type structure, and structural design is simpler, the cost is lower, and is provided with the lug portion that is connected with first torsional spring, first torsional spring on the framework, is convenient for first torsional spring, second torsional spring and the assembly of framework.

Detailed Description
As shown in fig. 1 and 2, an embodiment of the present invention is an integral type valve mechanism, including a frame 10, an unlocking transmission assembly 20, an upper valve 11, and a lower valve 12, which are arranged on the frame 10, the unlocking transmission assembly 20 includes a first unlocking crank arm 21, a first torsion spring 22, a second unlocking crank arm 23, a second torsion spring 24, an upper connecting rod 25, a lower connecting rod 26, a limiting rod 200, wherein the first unlocking crank arm 21, the second unlocking crank arm 23 are arranged on the frame 10, the upper connecting rod 25 is connected between the upper valve 11 and the first unlocking crank arm 21, the lower connecting rod 26 is connected between the lower valve 12 and the second unlocking crank arm 23, the first unlocking crank arm 21 and the second unlocking crank arm 23 are arranged on one end, and each limiting rod 200 is movably provided with a first pulley 201, a second pulley 201, a third pulley, a fourth pulley, and the first pulley 202 and the second pulley 202 are arranged on the limiting rod 200 side by side. As shown in fig. 1, the mechanism frame 10 is an integrated structure, a rotating shaft 101 is disposed on the mechanism frame 10, one end of each of the first unlocking crank arm 21 and the second unlocking crank arm 23 is rotatably disposed on the rotating shaft 101, and a hanging lug portion 102 connected to the first torsion spring 22 and the second torsion spring 24 is disposed on the mechanism frame 10. The mechanism frame adopts the integral type structure, and structural design is simpler, the cost is lower, and is provided with the lug portion that is connected with first torsional spring, first torsional spring on the framework, is convenient for first torsional spring, second torsional spring and the assembly of framework.
Two pulleys matched with the handcart are arranged on the limiting rods of the first unlocking connecting lever and the second unlocking connecting lever, so that the contact area between the pulleys and the handcart is increased, the handcart and the pulleys are prevented from being jammed, and the handcart, the first unlocking connecting lever and the second unlocking connecting lever are more flexibly and reliably transmitted. Therefore, the reliability of the work of the unlocking transmission assembly is improved, and the valve mechanism has the advantages of simple structure, safe and reliable performance, convenience in operation and long service life.
