Abstract
The utility model provides a longitudinal section is hollow ring -type that engineering machinery driver's cabin sealing strip, the outside of sealing strip is the bayonet socket strip of " U " font, and the inboard of sealing strip is gasbag, the gasbag be connected with the bayonet socket strip along length direction radially be equipped with cavity among the more than one in the gasbag wall of gasbag, the longitudinal section of well cavity is mirror image " C " word form, is equipped with curved inflation piece in the cooperation of cavity intracavity, all be equipped with the through -hole on the gasbag wall near bayonet socket strip side that the cavity corresponds in every, the through -hole has a perfect understanding with well cavity. The axial interval of two adjacent well cavitys is 10 -30mm. The material of inflation piece is glued for meeting the water inflation. Be equipped with the skeleton of U font in the bayonet socket strip along the length direction cooperation.
Description
Technical field
The utility model belongs to sealing accessory appliances field, is specifically related to a kind of engineering machinery driving cabin sealing band.
Background technology
The sealing of construction-vehicle cab side door mainly completes by sealing band, and with air bag on sealing band, air bag and cab frame have extruded sealing function.There is deviation in the air bag cross section of existing sealing band, can not well fit when carrying out side door sealing, particularly easy poor sealing around the corner, the situation of leaking.
Utility model content
For the poor sealing, the situation such as to leak that exist when solving existing sealing band sealing side door, the utility model devises a kind of engineering machinery driving cabin sealing band.
A kind of engineering machinery driving cabin sealing band, the outside of sealing band is the bayonet strip 1 of " U " font, the inner side of sealing band be connected along its length with bayonet strip 1 air bag 2, air bag 2 vertical section be the ring-type of hollow, in the airbag wall 21 of described air bag 2, radial direction is provided with more than one cavity, the vertical section of cavity is mirror image " C " shape, coordinates the expanding block 4 being provided with arc in cavity;
The airbag wall 21 of close bayonet strip 1 side that each cavity is corresponding is equipped with through hole 5, and through hole 5 is through with cavity.
The axial spacing of adjacent two cavities is 10-30mm.
The material of expanding block 4 is water-swellable glue.
The skeleton 3 being provided with U-shaped is coordinated along its length in described bayonet strip 1.
Advantageous Effects of the present utility model:
(1, the utility model devises expanding block in the airbag wall of air bag, the material of expanding block is water-swellable glue, and through hole is provided with on the airbag wall that expanding block is corresponding, when causing leaking because of poor sealing and flowing to the air bag in operator's compartment, current flow in cavity along through hole, expanding block is met water and is expanded, and produces the shape that stress corrects air bag, makes sealing band carry out effective sealing.
(2, the axial spacing of adjacent two cavities of the present utility model is 10-30mm, the distribution density of cavity is moderate, can carry out rectification sealing by actv., solve the water leakage situation caused because laminating degree in turning is poor simultaneously to each section of air bag.
(3, the utility model structure is simple, design ingenious, utilize the expanding block of distribution to realize the water-swellable sealing of sealing band, result of use is good, and sealing efficiency is high.
Accompanying drawing explanation
Fig. 1 vertical section structure schematic diagram of the present utility model.
Sequence number in upper figure: bayonet strip 1, air bag 2, airbag wall 21, skeleton 3, expanding block 4, through hole 5.
Detailed description of the invention
See Fig. 1, a kind of engineering machinery driving cabin sealing band, the outside of sealing band is the bayonet strip 1 of " U " font, the inner side of sealing band be connected along its length with bayonet strip 1 air bag 2, air bag 2 vertical section be the ring-type of hollow, in the airbag wall 21 of described air bag 2, radial direction is provided with more than one cavity, the vertical section of cavity is mirror image " C " shape, coordinates the expanding block 4 being provided with arc in cavity;
The airbag wall 21 of close bayonet strip 1 side that each cavity is corresponding is equipped with through hole 5, and through hole 5 is through with cavity.
The axial spacing of adjacent two cavities is 10-30mm.
The material of expanding block 4 is water-swellable glue.
The skeleton 3 being provided with U-shaped is coordinated along its length in described bayonet strip 1.
The material of described bayonet strip 1 and airbag wall 21 is elastic caoutchouc.
