Since the front end of the extension bar of electric pushrod is equipped with opening, and set on the extension bar of the electric pushrod at rubber ring rear
There is air vent, therefore when grafting groove is inserted into the front end of extension bar, the air in grafting groove is able to enter extension bar simultaneously
It is discharged from air vent, preventing the gas in grafting groove from being compressed causes extension bar and measuring head to assemble loosely.For different shaped
Number the different test requests (as required test area different) of elevator door need using different size of measuring head.Using
Structure of the invention, convenient for replacing suitable measuring head according to different test requests, it is only necessary to push away former measuring head by electronic
The grafting groove for pulling, being again inserted into extension bar on suitable measuring head on the extension bar of bar.Due to rubber ring outer diameter
Greater than the diameter of extension bar compatible with grafting groove, therefore rubber ring can form close-fitting between grafting groove inner wall
It closes, installs rear relatively firm, can prevent measuring head from voluntarily splitting away off on extension bar due to vibration etc..
Two rows connection is bolted in adjacent two rows of link bolt hole, link bolt hole is provided with four rows altogether, in this way
Two rows connection bolt is with respect to connecting plate and its link bolt hole with regard to the link position different there are three types of front-rear position.Elevator door is left
When the front-rear position difference of right two sides crack between a door and its frame, the anteroposterior position of L-type plate can be adjusted by adjusting the link position of connection bolt
It sets, it is ensured that the installation site of the second hollow crossbeam and the second hollow auxiliary beam is left and right directions, i.e., each parallel to elevator door, into
And ensure the direction of the pressure on top surface of electric pushrod perpendicular to elevator door.
