Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle technology, and in particular to an engineering vehicle window lock. Background Technology

[0002] Construction vehicles are tools used in construction projects. They can significantly accelerate construction progress and greatly reduce manpower, primarily serving functions such as transportation, excavation, and emergency repair. Common construction vehicles include: heavy transport vehicles, large cranes, excavators, bulldozers, road rollers, loaders, and power repair vehicles.

[0003] The window locks on engineering vehicles are a type of lock used to secure the glass after the windows are closed, preventing potential safety risks or equipment damage from opening windows carelessly in dusty, wet, or confined spaces.

[0004] The patent, published under the number CN215332112U, is titled "An Engineering Vehicle Window Lock." It includes a vehicle frame with a window glass slidably connected to its inner side. Horizontal plates located in front of the window glass are fixedly installed on both the upper and lower sides of the inner cavity of the vehicle frame. Limiting grooves are formed on opposite sides of the two horizontal plates. This lock has the advantage of limiting the movement of the window glass and preventing its displacement.

[0005] In use, the device described in the aforementioned patent rotates a movable rod, which in turn drives a first gear to rotate. The meshing of the first and second gears causes a rotating rod to rotate, which in turn drives a take-up roller to take in the pull rope, causing the limiting rod to leave the limiting groove and allowing the car window to move. When moving, the movable rod needs to be rotated and then used to pull the car window. At the same time as pulling the car window, a spring pushes the limiting rod in the opposite direction, so that the user maintains an external force applied to the movable rod while pulling the car window, making it relatively difficult to pull the car window. Utility Model Content

[0006] The purpose of this utility model is to provide a window lock for engineering vehicles, which can easily open the window lock to move the window glass, and the operation is labor-saving.

[0007] To achieve the above objectives, a window lock for an engineering vehicle is provided, comprising a window frame, within which a fixed window and a movable window are installed, the movable window sliding within the window frame. The movable window is located on one side of the fixed window. Limiting grooves are equidistantly formed at the top and bottom of the inner wall of the window frame, with the limiting grooves located on the side of the movable window away from the fixed window. A lock is fixedly connected to the surface of the movable window away from the fixed window. The lock consists of an insertion rod, a housing, a steel wire rope, a second spring, a baffle, and a connecting rod. The housing is fixedly connected to the surface of the movable window. A first chamber and a second chamber are formed in the middle of the housing, with the first chamber located on the upper and lower sides of the second chamber, respectively. The insertion rod is located in the first chamber, with the end of the insertion rod away from the second chamber penetrating the housing. The insertion rod is slidably connected to the outer casing. The end of the insertion rod away from the second chamber is fixed to the window frame in conjunction with a limiting groove. A baffle is fixedly connected to the end of the insertion rod facing the second chamber and is slidably connected to the surface of the first chamber. A connecting rod is located in the second chamber, with both ends penetrating the outer casing and slidably connected to it. A steel wire rope is fixedly connected to the upper and lower ends of the connecting rod, with the other end extending into the first chamber. The other end of the steel wire rope is fixedly connected to the baffle. A second spring is fixedly connected to the side of the first chamber facing the second chamber, with its other end fixedly connected to the baffle. The second spring wraps around the outside of the steel wire rope, and the steel wire rope passes through the second spring. This design allows for easy unlocking of the car window and movement of the window glass, simplifying operation.

[0008] According to the aforementioned engineering vehicle window lock, a first spring is fixedly connected to the second chamber, and the first spring is located on the left and right sides of the second chamber respectively. One end of the first spring is fixedly connected to a connecting rod. The first spring is used to assist the second spring in resetting the connecting rod after the user stops controlling the lock.

[0009] According to the aforementioned engineering vehicle window lock, push-pull plates are fixedly connected to both ends of the connecting rod. The push-pull plates increase the contact surface, facilitating user operation.

[0010] According to the aforementioned engineering vehicle window lock, the limiting groove has an inclined surface on the side facing the housing, and the inclined surface of the limiting groove slopes from the side facing the movable window to the other side. This is to prevent dust and impurities from accumulating in the limiting groove, thereby affecting the fit between the insertion rod and the limiting groove.

[0011] The above solution has the following advantages: By pushing or pulling the connecting rod according to the required direction of movement of the sliding window, the steel wire rope pulls the baffle, causing the insertion rod to leave the limiting groove and the sliding window to move within the window frame. After being released, the second spring causes the insertion rod to return to the limiting groove and lock the sliding window. The operation is simple and labor-saving.
