Description

Pressure equalizing support frame for power dispatching chair

technical field

The utility model relates to an auxiliary device of an electric power dispatching chair, in particular to a pressure equalizing support frame of the electric power dispatching chair.

Background technique

As the front-line personnel of the power grid operation, the power dispatcher needs to monitor the operation status of the power grid at all times and implement a 24-hour uninterrupted duty mode. Its special electric dispatching chair can alleviate the fatigue of dispatchers on duty to a certain extent. There is only one air rod connected between the chassis and the seat board of the current electric dispatching chair. As the personnel adjusts the backrest angle of the dispatching chair, the force on the connection between the air rod and the seat board will be uneven, which will easily cause the connection between the air rod and the seat board. The breakage will shorten the service life of the power dispatching chair. Known by retrieval, do not see the report by being sleeved with pressure equalizing support frame on air bar at present.

Contents of the invention

The purpose of this utility model is to provide a pressure equalizing support on the air rod between the chassis and the seat board of the electric power dispatching chair, thereby preventing the breakage of the connection between the air rod and the seat board, improving the service life of the electric power dispatching chair, and the structure Simple, easy-to-use pressure equalizing support frame for power dispatching chairs.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the pressure equalizing support frame of the electric power dispatching chair includes a semicircular tube, a triangular support plate and a fixing bolt, and the feature is that the semicircular tube is provided with two left and right , the rear edges of the left and right semicircular pipes are movably connected by the rotating shaft; the front edges of the left and right semicircular pipes are provided with butt plates connected as one, and the two butt plates are fixedly connected by fixing bolts; the triangular support plates are equidistant There are 3-4 pieces, one of which is welded and fixed with the side wall of the semicircular tube, and the other right-angled edge and the upper edge of the semicircular tube are on a horizontal plane. Supporting plate, the height of the horizontal supporting plate is 5-10mm higher than the upper edge of the semicircular pipe.

The utility model is also implemented through the following measures: the height of the semicircular tube is 40mm, and the inner diameter is 48mm.

The beneficial effect of the utility model is that: the pressure equalizing support frame of the power dispatching chair has a simple structure, low manufacturing cost, easy installation and convenient use, and can balance the force on the joint between the air rod and the seat when adjusting the dispatching chair, effectively The deflection of the air rod under pressure is avoided, so that the connection between the air rod and the seat plate will not be broken, and the service life of the electric dispatching chair is prolonged.

Description of drawings

Detailed ways

Make the utility model with reference to Fig. 1, Fig. 2. The pressure equalizing support frame of the power dispatching chair includes a semicircular tube 1, a triangular support plate 2 and a fixing bolt 3, and is characterized in that: the semicircular tube 1 is provided with two left and right sides, and the rear edges of the left and right semicircular tubes 1 pass through The rotating shaft 4 is movably connected, so that the two semicircular tubes 1 can rotate along the rotating shaft 4 to realize opening and closing; the front edge of the left and right semicircular tubes 1 is provided with a butt plate 5 connected as one, and the two butt plates 5 are connected by fixing bolts 3 fixed connection; said triangular support plates 2 are equidistantly provided with 3-4 pieces, one of which is fixed by welding with the side wall of the semicircular pipe 1, and the other right angle and the upper edge of the semicircular pipe 1 are on a horizontal plane , the outer end of the upper right-angled side of the triangular support plate 2 is provided with a horizontal supporting plate 6, and the height of the horizontal supporting plate 6 is 5-10 mm higher than the upper edge of the semicircular pipe 1. When using the utility model, the two semicircular tubes 1 are stuck on the air rods on the bottom side of the electric power dispatching chair, the horizontal supporting plate 6 is pushed against the bottom side of the seat plate of the electric power dispatching chair, and the fixing bolts 3 are tightened to fix it. In use, no matter what the operator's posture is, the seat plate can be guaranteed to be flat, so that the air rod will not be deflected under pressure, and the connection between the air rod and the seat plate will not be broken. the

As an improvement of the present utility model: the height of the semicircular tube 1 is 40 mm, and the inner diameter is 48 mm.
