Description

Technical Field

[0001] This utility model relates to a flexible rear window locking device for non-road machinery, belonging to the field of non-road machinery cockpit technology. Background Technology

[0002] The locking plates of rear window locks in the cabs of existing off-road machinery (such as excavators, loaders, and tractors) are often rigid or have only a slight degree of elasticity. However, the doors and windows of off-road machinery often experience significant and frequent vibrations due to the vehicle body, which can easily lead to wear on the lock claws and unreliable locking. Since window locks are often related to driver safety, it is necessary to improve their locking reliability.

[0003] In addition, the rear window locks of traditional off-road machinery cockpits generally have a single function and cannot achieve multi-level opening and closing.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a non-road mechanical elastic rear window lock device that can lock multiple windows simultaneously, enabling flexible switching between tightly closed and half-open states, improving the user's driving experience, and enhancing locking reliability under vibration conditions.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A non-road mechanical resilient rear window locking device includes a lock handle assembly and a lock plate. The lock handle assembly is fixed to one side of the glass, and the side of the glass away from the lock handle assembly is connected to the frame via a hinge. The lock plate is fixed to the frame. The lock handle assembly includes a lock handle, an inner pressure plate, and an outer pressure plate arranged sequentially, with the inner and outer pressure plates installed on both sides of the glass; the lock handle is provided with lock claw one and lock claw two that cooperate with the lock plate; The locking plate is equipped with a locking plate, which has a long arm and a semi-circular structure, and a limiting plate is provided behind the locking plate.

[0007] Furthermore, long bolts are inserted into the lock handle, inner pressure plate, glass, and outer pressure plate, while short bolts are inserted into the inner pressure plate, glass, and outer pressure plate.

[0008] Furthermore, the head of the long bolt is located inside the outer pressure plate, and a bolt cap is installed on the head; a self-locking nut is installed on the tail of the long bolt, and a locking handle cap is fastened to the self-locking nut.

[0009] Furthermore, the head of the short bolt is embedded in the outer pressure plate, and the tail of the short bolt passes through the inner pressure plate. A self-locking nut is installed on the tail, and a nut cap is fastened to the self-locking nut.

[0010] Furthermore, sealing gaskets are installed at the joints between the inner pressure plate, the outer pressure plate, and the glass.

[0011] Furthermore, a limiting groove is provided on the end of the lock handle near the inner pressure plate, and a boss is provided on the side of the inner pressure plate near the lock handle. The boss and the limiting groove cooperate to limit the rotation angle of the lock handle.

[0012] Furthermore, the first and second locking claws are arranged side by side, and both are columnar structures.

[0013] Furthermore, the locking plate is fixed to the frame by bolts, and the locking plate is made of nylon.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention features two parallel locking claws on the lock handle. By engaging different locking claws with the locking plate, it allows for flexible switching between closed and partially open states, enhancing the user's driving experience.

[0015] This invention employs an elastic locking design. The locking plate on the locking plate is designed as an elastic structure with a long arm and a semi-circle, capable of deformation to lock the locking claw. During vibration, the elastic locking plate can deform slightly and rebound, maintaining the clamping force on the locking claw, avoiding rigid collisions and loosening, and improving locking reliability.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown in the diagram, this utility model provides a non-road mechanical elastic rear window lock device, including a lock handle assembly 4 and a lock plate 5. The lock handle assembly 4 is fixedly connected to one side of the glass 3, and the side of the glass 3 away from the lock handle assembly 4 is connected to the frame 2 via a hinge 1. The lock plate 5 is fixedly connected to the frame 2. The user can rotate the lock handle assembly 4 and the lock plate 5 to lock or partially open the door and window.

[0021] The lock assembly 4 includes a lock handle 41, an inner pressure plate 43, and an outer pressure plate 44 arranged sequentially. The inner pressure plate 43 and the outer pressure plate 44 are installed on both sides of the glass 3. Long bolts 42 are inserted into the lock handle 41, the inner pressure plate 43, the glass 3, and the outer pressure plate 44, and short bolts 46 are inserted into the inner pressure plate 43, the glass 3, and the outer pressure plate 44.

[0022] The head of the long bolt 42 is located inside the outer pressure plate 44, and a bolt cap 49 is installed on the head; a self-locking nut is installed on the tail of the long bolt 42, and a locking handle cap 48 is fastened to the self-locking nut.

[0023] The head of the short bolt 46 is embedded in the outer pressure plate 44, and the tail of the short bolt 46 passes through the inner pressure plate 43. A self-locking nut is installed on the tail, and a nut cap 47 is fastened to the self-locking nut.

[0024] Sealing gaskets 45 are installed at the connection points between the inner pressure plate 43, the outer pressure plate 44 and the glass 3.

[0025] The locking handle 41 is provided with a limiting groove 413 at the end near the inner pressure plate 43, and the inner pressure plate 43 is provided with a boss 431 on the side near the locking handle 41. The boss 431 cooperates with the limiting groove 413 to allow the locking handle 41 to rotate around the long bolt 42 within a specified angle.

[0026] The lock handle 41 is provided with a first lock claw 411 and a second lock claw 412 that cooperate with the lock plate 5. The first lock claw 411 and the second lock claw 412 are arranged side by side and are both columnar structures. The first lock claw 411 is located close to the inner pressure plate 43.

[0027] The locking plate 5 is bolted to the frame 2. The locking plate 5 is made of nylon, which has self-lubricating, wear-resistant, and fatigue-resistant properties. The locking plate 5 is provided with a locking piece 51, which has a long arm and a semi-circular structure with a certain elastic deformation space. The semi-circular structure can reliably lock the locking claw 411 and locking claw 412 of the locking handle 41.

[0028] A limiting plate 52 is provided behind the locking piece 51, which can provide support to the locking piece 51 when the force on the locking piece 51 is too great.

[0029] The specific working principle of this utility model is as follows: After glass 3 is closed, rotate lock handle 41 to engage the first locking claw 411 of lock handle 41 into the locking plate 51 of lock plate 5, thus closing the door and window tightly. Engage the second locking claw 412 of lock handle 41 into the locking plate 51 of lock plate 5, thus opening the door and window partially.

[0030] The locking plate 51 in this utility model has a long arm and a semi-circular structure with a certain elastic deformation space, which can reliably lock the locking claw of the lock handle 41 and overcome the defects such as easy wear of the locking claw and unreliable locking under vibration conditions.
