The technical scheme is as follows: a lock device of engineering machinery comprises a support, a connecting piece and a lock bolt; the support is assembled on the cab upright post; the lock bolt is assembled on the side window; the support and the lock bolt are connected through the connecting piece; the support comprises a hinge pin; the connecting piece comprises a connecting body, a closed locking port and an open locking port; the connecting body is in shaft fit with the hinge bolt hole; the closed locking port and the open locking port are arranged at two ends of the connecting body; when the hinge lock is used, the connecting piece rotates clockwise by taking the hinge bolt as a center, the open locking port is clamped with the lock bolt, and the side window is in an open state; in addition, the connecting piece rotates anticlockwise by taking the hinge bolt as a center, the closed locking port is clamped with the lock bolt, and the side window is in a closed state. When the closed locking port and the open locking port are not clamped with the lock plunger, the side window is in a large open state.
Preferably, the swinging amplitude of the connecting piece is reduced in order to ensure the reliability of the closing state of the side window. The support also comprises a positioning bolt, and the positioning bolt is arranged below the hinge bolt; the connecting piece also comprises a waist-shaped positioning hole; when the side window is in a closed state, the positioning hole is in hole shaft fit with the positioning bolt.
Preferably, the locking notch is conveniently closed and locked with the lock bolt, so that the opening locking notch and the lock bolt are prevented from falling off. The cross section of the closed locking port is concave; the cross section of the open locking port is Z-shaped.
Preferably, the number of tools is reduced in order to increase the use of the connector. The connector also includes a wrench hole, the wrench hole being hexagonal.
The beneficial effects are that: the utility model has simple structure, high reliability and convenient maintenance, and can meet the use requirements of different working conditions.

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
FIG. 1 is a schematic view of a structure of the present utility model;
FIG. 2 is a schematic diagram of a transitional state structure according to the present utility model;
FIG. 3 is a schematic view of a second embodiment of the present utility model;
fig. 4 is a schematic view of a partial explosion of the present utility model.
Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
As shown in fig. 4, a lock device of a construction machine includes a bracket 1, a connecting member 2, and a lock bolt 3; the support 1 is assembled on the cab pillar 4; the lock bolt 3 is assembled on the side window 5; the support 1 is connected with the lock bolt 3 through the connecting piece 2. The support 1 comprises a hinge pin 11 and a positioning pin 12. The connector 2 includes a connector body 21, a closed-notch 22, an open-notch 23, a positioning hole 24, and a spanner hole 25. The connecting body 21 is in shaft fit with the hole of the hinge pin 11, and the closed locking notch 22 and the open locking notch 23 are arranged at two ends of the connecting body 21. The positioning bolt 12 is arranged below the hinge bolt 11.
The lock device of the utility model can enable the side window 5 to be respectively in three states, namely a closed state, an open state and a wide open state, wherein the open state mainly aims at ventilation and ventilation in a cab. As shown in fig. 1, the side window 5 is in a closed state, and the positioning hole 24 is in hole shaft fit with the positioning bolt 12, so that the locking bolt 3 can be effectively prevented from falling off from the closing locking port 22, and meanwhile, noise generated by vibration of the connecting piece 2 is reduced. When the side window 5 is in the closed state to the open state, the connecting piece 2 needs to be pulled outwards along the axial direction of the positioning bolt 12, the positioning hole 24 is separated from the positioning bolt 12, as shown in fig. 2, the connecting piece 2 is rotated clockwise around the hinge bolt 11 as the center, meanwhile, the side window 5 is pushed, the open locking hole 23 is engaged with the lock bolt 3, and the side window 5 is in the open state, as shown in fig. 3. The cross section of the open locking port 23 is Z-shaped, so that the open locking port 23 can be effectively ensured not to be separated from the lock bolt 3. When the side window 5 returns to the closed state, the connector 2 needs to rotate anticlockwise around the hinge pin 11, and simultaneously pulls the side window 5, the closing locking opening 23 is engaged with the lock bolt 3, and the side window 5 is in the closed state. Because the cross section of the closed locking opening 22 is concave, the connecting piece 2 can move along the axial direction of the hinge pin, but does not separate from the hinge pin, and the positioning hole 24 is a kidney-shaped hole, so that the positioning hole 24 is easier to separate from the positioning pin 12, and the side window 5 is easier to switch between a closed state and an open state, and is convenient to use. When neither the closed locking notch 22 nor the open locking notch 23 is engaged with the lock bolt 3, the side window 5 is in a wide open state.
In order to adapt to the requirements of different models and industries, a plurality of open locking openings 23 can be arranged on the connecting piece 2, in addition, the wrench holes 25 are hexagonal, match with the shapes of common fasteners, and can be used as a wrench, so that the application range of the wrench can be further improved.
Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications and variations may be made to the above-described embodiments without departing from the spirit of the utility model, such as the use of the present utility model on a door or hood, while remaining within the scope of the present utility model.
