The technical scheme of the utility model is that:
the utility model provides an expander swing arm formula oil level indicator, is including being used for with the fixed connecting seat of expander left side ripple piece or right side ripple piece, be used for with the fixing base of expander shell side founding wall connection, its technical essential is: the improved multifunctional lifting device is characterized in that a vertical guide rail is arranged on the fixing seat, a sliding block is arranged on the vertical guide rail, a connecting rod is hinged between the sliding block and the connecting seat, the sliding block is connected with a swing arm towards the side of the shell side vertical wall, the other end of the swing arm is fixedly connected with the inner end of a supporting shaft arranged on the shell side vertical wall, a pointer is fixed at the outer end of the supporting shaft, an indicating dial matched with the pointer is arranged on the outer side surface of the shell side vertical wall, a long hole is formed in one end of the sliding block connected with the swing arm, and the tip of a positioning bolt penetrates through the long hole to be fixed on the sliding block.
In the swing arm type oil level indicator for the expander, the center line of the support shaft is perpendicular to the center line of the vertical guide rail and is located in the same vertical plane.
According to the swing arm type oil level indicator of the expander, the connecting seat and the sliding block are respectively provided with the U-shaped openings corresponding to the connecting rod, and two ends of the connecting rod are inserted into the U-shaped openings of the connecting seat and the sliding block and are connected through the rotating shaft.
The utility model has the advantages that:
during the use, the utility model discloses convert the transverse motion of expander main part into the longitudinal motion of slider along perpendicular guide rail, the slider converts its longitudinal motion into the rotation of swing arm around the back shaft central line again, and then drives the pointer and swing at the settlement within range, and the staff is through observing the position that the pointer corresponds the dial plate, can know the motion state of expander main part in the shell, degree of inflation promptly, oil level height wherein. Thereby solve the running state of current lateral motion's expander main part and be unfavorable for the problem of observation through the table window, indicate clearly, make things convenient for the staff to observe.

In the figure: 1. the mechanical expansion device comprises a dial plate, 2 pointers, 3 vertical guide rails, 4 support shafts, 5 sliders, 6 swing arms, 7 connecting rods, 8 connecting seats, 9 fixing seats, 10 shell side vertical walls, 11 long holes, 12 positioning bolts and 13 box type expanders.
Detailed Description
The invention is described in detail according to the attached drawings.
As shown in fig. 1 to 7, the swing arm type oil level indicator of the expander comprises a connecting seat 8 for being fixed with a left corrugated sheet or a right corrugated sheet of the expander and a fixed seat 9 for being connected with a side vertical wall 10 of an outer shell of the expander. The fixing seat 9 is provided with a vertical guide rail 3, the vertical guide rail 3 is provided with a sliding block 5, and a connecting rod 7 is hinged between the sliding block 5 and the connecting seat 8. The slide block 5 is connected with a swing arm 6 towards the side of the shell side vertical wall, the other end of the swing arm 6 is fixedly connected with the inner end of a support shaft 4 arranged on the shell side vertical wall 10, and a pointer 2 is fixed at the outer end of the support shaft 4. The outer side surface of the shell side vertical wall 10 is provided with an arc-shaped indicating dial 1 matched with the pointer 2. One end of the swing arm 6 connected with the sliding block 5 is provided with a long hole 11, and the tip of the positioning bolt 12 penetrates through the long hole 11 and is fixed on the sliding block 5.
In this embodiment, the center line of the support shaft 4 is perpendicular to the center line of the vertical guide rail 3, and is located in the same vertical plane. The connecting seat 8 and the sliding block 5 are respectively provided with a U-shaped opening corresponding to the connecting rod 7, and two ends of the connecting rod 7 are inserted into the U-shaped openings of the connecting seat 8 and the sliding block 5 and are connected by a rotating shaft.
