Abstract
Description
Technical Field
[0001] This utility model relates to the field of window locking devices, and more particularly to window locking devices for logging vehicles. Background Technology
[0002] A logging truck is a piece of equipment used for logging operations in forests. Its cab windows use curved resin glass, 10-12mm thick, to prevent the logging machine chain from breaking and flying into the cab, thus protecting the driver. The resin glass is relatively soft, and the curved design helps to maintain its sturdiness, preventing rattling during machine operation. The window locking device is the opening and closing mechanism for the logging truck's cab windows, used to control their operation.
[0003] Traditional cab windows are flat, consisting of two panes of glass mounted on rails. Opening and closing is achieved by sliding the glass left and right. Locking points are installed on the glass, and latches are mounted on the window frame; pushing the locking points into the latches locks the window. However, when the cab window glass is curved, sliding the glass can cause interference or poor sealing. The rails for curved glass also have a certain curvature, which is inconvenient for manufacturing. Furthermore, windows composed of two panes cannot be fully opened, as one pane always occupies space. In emergencies where the cab door cannot be opened, this hinders the driver's escape through the window (resin glass is unbreakable by a safety hammer). Therefore, a window locking device for logging trucks is needed. Utility Model Content
[0004] The purpose of this invention is to provide a window locking device for logging vehicles in forestry, thereby solving existing technical problems.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The window locking device of the logging vehicle includes a spring cotter pin, a window lock body, window locking ball bearings, and a window lock connecting rod. The spring cotter pin is inserted into the upper and lower ends of one side of the window lock body. Two window locking balls are respectively provided at the upper and lower ends of the other side of the window lock body. A first fixing ear and a second fixing ear are respectively provided at the upper and lower ends of one side of the window lock body. The first fixing ear and the second fixing ear are arranged opposite to each other, and the two window locking balls are located at one end between the first fixing ear and the second fixing ear. One end of the window lock connecting rod is rotatably connected to the end between the first fixing ear and the second fixing ear, and the window lock connecting rod is in contact with the window locking ball bearings.
[0006] Furthermore, two cotter pin sleeves are respectively provided at the upper and lower ends of one side of the window lock body, and the spring cotter pin is inserted into the two cotter pin sleeves.
[0007] Furthermore, two positioning lock ball holes are respectively provided at the upper and lower ends of the other side of the window lock body. One end of the window lock positioning lock ball is set in the positioning lock ball hole, and the other end of the window lock positioning lock ball extends out of the positioning lock ball hole. Furthermore, the window lock body is configured with an arc-shaped structure, and screw holes are respectively provided at one end of the first fixing ear and the second fixing ear.
[0008] Furthermore, the window locking rod is rotatably connected between the first fixing lug and the second fixing lug by an internal hexagonal flat head screw, and the other end of the window locking rod is provided with a hexagonal flange bolt.
[0009] Furthermore, one end of the window lock linkage is provided with a positioning sleeve, and the outer side of the positioning sleeve is provided with vertical positioning grooves at intervals.

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.
[0013] like Figure 1-9 As shown, the window locking device of the logging vehicle includes a spring cotter pin 1, a window lock body 2, window locking ball 4, and a window lock connecting rod 6. The spring cotter pin 1 is inserted into the upper and lower ends of one side of the window lock body 2. Two window locking balls 4 are respectively provided at the upper and lower ends of the other side of the window lock body 2. A first fixing ear 9 and a second fixing ear 10 are respectively provided at the upper and lower ends of one side of the window lock body 2. The first fixing ear 9 and the second fixing ear 10 are arranged opposite to each other, and the two window locking balls 4 are located at one end between the first fixing ear 9 and the second fixing ear 10. One end of the window lock connecting rod 6 is rotatably connected to the end between the first fixing ear 9 and the second fixing ear 10, so that the window lock connecting rod and the window lock body are folded together, and the window lock connecting rod 6 is in contact with the window locking ball 4. In use, the curved resin glass is installed on the window frame 15 using glass glue. One end of the window frame 15 is connected to the main frame 16 of the cab by a hinge. The window lock body 2 is connected to the other end of the window frame 15 by a spring cotter pin 1. A sealing strip is wrapped around the window frame. The window lock linkage 6 is connected to the main frame 16 of the cab by hexagonal flange bolts 5. During installation, the window locking device of this utility model is connected to the window frame 15 by a spring cotter pin 1. In special circumstances where the cab door cannot be opened, pulling the spring cotter pin 1 will fully open the window, facilitating the driver's escape through the window.
[0014] like Figure 3-4As shown, two cotter pin sleeves 7 are respectively provided at the upper and lower ends of one side of the window lock body 2, and the spring cotter pin 1 is inserted into the two cotter pin sleeves 7. Two positioning lock ball holes 8 are respectively provided at the upper and lower ends of the other side of the window lock body 2. One end of the window lock positioning lock ball 4 is set in the positioning lock ball hole 8, and the other end of the window lock positioning lock ball 4 extends out of the positioning lock ball hole 8. The window lock body 2 is set with an arc-shaped structure, and one end of the first fixing ear 9 and the second fixing ear 10 are respectively provided with screw holes 13. The window lock connecting rod 6 is rotatably connected between the first fixing ear 9 and the second fixing ear 10 by an internal hexagonal flat round head screw 3. The internal hexagonal flat round head screw 3 passes through the first fixing ear 9, the window lock connecting rod 6 and the second fixing ear 10 in sequence, so that the window lock connecting rod 6 is rotatably connected to the first fixing ear 9 and the second fixing ear 10. The other end of the window lock connecting rod 6 is provided with a hexagonal flange bolt 5. In use, a cotter pin sleeve is installed on the window frame 15. When connecting, the cotter pin sleeve on the window frame is between the two cotter pin sleeves of the window lock body. Then, the window lock body and the window frame can be connected by passing the spring cotter pin through the cotter pin sleeves in sequence. When the driver's cab door cannot be opened, the window can be fully opened by pulling the spring cotter pin, which makes it convenient for the driver to escape through the window.
[0015] like Figure 3 and Figure 5 As shown, one end of the window locking rod 6 is provided with a positioning sleeve 11, and the outer side of the positioning sleeve 11 is provided with vertical positioning grooves 12 at intervals. The other end of the window locking bead 4 is in contact with the positioning groove 12. The size of the window locking bead 4 is the same as the size of the positioning groove 12, so that the window locking bead 4 can be locked in the positioning groove 12. The hexagonal flat head screw 3 passes through the first fixing ear 9, the positioning sleeve 11 of the window locking rod 6 and the second fixing ear 10 in sequence, so that the window locking rod 6 is rotatably connected to the first fixing ear 9 and the second fixing ear 10.
[0016] Working principle When the driver wants to close the window, he pulls the window lock body 2 inward, which moves the window closer to the cab. Then he pushes the window lock body 2 toward the cab main frame 16, which causes the window lock body 2 and the window lock linkage 6 to fold up. The window is pressed tightly against the cab main frame by the sealing strip. Due to the elasticity of the sealing strip, the window lock will be firmly locked. When the driver wants to open the window, they push the window lock body 2 outwards, and the window will open. The window lock ball 4 engages with the positioning groove 12 of the positioning sleeve 11 of the window lock linkage 6, which controls the size of the window opening. In special circumstances, pulling out the spring cotter pin 1 can fully open the window.
[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
