Abstract
The utility model discloses a locking device for sealing and positioning of a push-back window of an engineering machine driving cab. The locking device comprises a driving cab rear pillar and a push-back window which are articulated with each other, and is characterized in that a positioning locking handle is articulated with the lower edge of the inner side of the pushback window; a sliding groove is formed on the positioning locking handle; a plurality of positioning grooves are formed at the upper side of the sliding groove; a locking pillar matched with the positioning grooves is fixedly arranged on the sidewall of the driving cab rear pillar; a sealing groove is formed on the driving cab rear pillar; and a sealing cushion is arranged on the inner wall of the sealing groove. The locking device for sealing and positioning of the push-back window of the engineering machine driving cab is characterized in that the push-back window can be opened by three angles according to requirements while being opened outwards, and when being closed, the push-back window is fastened to the locking pillar through the positioning locking handle due to rebound pressure of a sealing bar on the driving cab rear pillar, and therefore, the push-back window can be opened by the corresponding angle according to requirements.
Description
Technical field
The utility model relates to a kind of engineering machinery driving cabin pusher window sealing positioning and locking device.
Background technology
At present, be installed in the unlatching location of engineering machinery driving cabin pusher window both sides and close locking device, usual method is in pusher window both sides an air spring to be installed respectively, uncontrollable folding angle when opening, because this vehicle has multiple model, need choosing dress different accessories, install very inconvenient.
The utility model content
The purpose of this utility model provides a kind of engineering machinery driving cabin pusher window sealing positioning and locking device, the pusher window can be opened three angles as required when outwards opening, when closing because the driver's cabin rear column on the weather strip bounce pressure, by the positioning and locking handle pusher window is held on the lock, the pusher window can be opened respective angles as required.
The technical solution of the utility model is as follows:
A kind of engineering machinery driving cabin pusher window sealing positioning and locking device, include the driver's cabin rear pillar, the pusher window that are hinged, the lower limb of described pusher window inboard is hinged with the positioning and locking handle, have chute on the positioning and locking handle, the chute upside is provided with several locating slots, be fixed with the lock that is complementary with locating slot on the driver's cabin rear pillar sidewall, have seal groove on the described driver's cabin rear pillar, the seal groove inwall is provided with sealing mat.
The front end of described chute has the deep-slotted chip breaker of extension.
Positioning and locking handle of the present utility model is installed on the pusher window by bolt, the while lock passes the positioning and locking handle and is welded on the driver's cabin rear column, the pusher window can be opened three angles as required when outwards opening, because of the weather strip bounce pressure on the driver's cabin rear column, by the positioning and locking handle pusher window is held on the lock when closing.
