It clamps to reach with loosening state, the clamping force of generation can achieve the purpose that stage frame is connect with stage foot.The attachment device knot
Structure is simple, and low in cost is advantage, but disadvantage is also quite obvious:
1, point type connects stress in a position, and forced area is small, causes local pressure point big, and the unexpected of stage moves and dash forward
When so stopping, local pressure can be bigger, leads to the abrasion of connection installation hole location, causes link position to loosen, or even will appear de-
It falls；
2, screw rod and stage foot stress are angled, and forced contact point is small, and it is wrong that the unexpected movement of stage forms forced contact point
Position forms bending stress, and fastening Luo bar is easily bent deformation, or even causes falling off for stage foot, causes stage to shake and collapses.
Utility model content
In view of this, the present invention provides a kind of locking devices for stage foot, are converted to face using point contact and connect
The design method of touching provides the locking device that stage frame is connected with stage foot, fastens stage frame and the connection of stage foot more,
Use process is safer, smaller to stage frame and the damage of stage foot, to improve the Build Security of stage.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that the utility model one kind for waving
The locking device of table foot, including screw rod, T-type sliding slot, connector, pressure equalization item and Y type bottom sealing plate, the side of the connector

The screw rod pushes pressure equalization item to squeeze stage foot by nut.
In order to further realize the utility model, the pressure equalization side is equipped with pressure equalization slot, and the other side is equipped with V
Type stress surface, the V-type stress surface are set to 90 degrees.
In order to further realize the utility model, the open end of the V-type stress surface and stage hem facing are closed, the V-type by
The top rounded corner in power face forms a buffer area.
In order to further realize the utility model, the connector is square aluminum material, and length and width are cut into 55mm long
Degree.
In order to further realize the utility model, nut is equipped with inside the T-type sliding slot, cooperation screw rod arrives nut check
In the T-type sliding slot of device, and it can be moved up and down with respect to T-type sliding slot.
In order to further realize the utility model, the lower end of the screw rod is provided with T-shaped slider.
In order to further realize the utility model, the connector is equipped with reinforcing rib.
Beneficial effect
1. the utility model is provided with pressure equalization item, pressure equalization item is provided with V-type stress surface, by original point contact
Become face contact, increase forced area, overall stability improves a lot.
2. the utility model pressure is equipped with reinforcing rib in the connector, the unexpected movement of stage can be prevented and stopped suddenly
When only, local pressure will lead to the abrasion deformation of connector, or even link position is caused to loosen, and stage foot is caused to fall off,
Whole fastness is also improved simultaneously.
3. the top of the utility model V-type stress surface is closed to form one by original right angle rounded corner with the stage hem facing of stage
Buffer area can slow down the shaking due to stage and the conduction of local pressure that generates, increase the stability of stage foot.
