Description

Technical Field

[0001] This utility model relates to the field of forklifts, specifically to a forklift hood opening lock. Background Technology

[0002] In forklift equipment, reliable locking and easy opening of the hood are crucial. Traditional forklift hood locks typically expose the unlocking handle directly outside the machine body. This design has significant drawbacks: firstly, the exposed handle lacks effective protection and is easily damaged by accidental collisions or scratches from goods, tools, or other foreign objects during forklift operation or parking, leading to accidental activation of the lock and a potential safety hazard of the hood accidentally popping open; secondly, the protruding handle structure may also obstruct the driver's operation or passage around the vehicle, affecting work efficiency and ease of operation. Therefore, there is an urgent need for a forklift hood lock structure that can effectively protect the unlocking handle and prevent accidental operation. Utility Model Content

[0003] The purpose of this utility model is to provide a forklift hood unlocking lock, which solves the problem of the lack of protection in the unlocking structure of existing forklift hood locks.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A forklift hood unlocking lock is disclosed, wherein the hood is hinged to the forklift body, and a cover plate is provided on the front side of the body. The unlocking lock includes a first lock located inside the body for locking the hood, the first lock including a locking hook rotatably located inside the body and an unlocking handle located at one end of the locking hook; the cover plate has a hand hole, and the end of the unlocking handle away from the locking hook extends to the hand hole; a protective plate is hinged to one side of the hand hole, and a second lock is provided on the protective plate, the second lock being used to lock the protective plate so that the protective plate closes the hand hole and covers the unlocking handle. At this time, the unlocking handle is in an inoperable state, which can prevent the unlocking handle from being accidentally triggered and prevent foreign objects from entering the forklift body.

[0006] As a further optimization of this utility model, a positioning frame is provided on the inner side of the machine cover, and the other end of the locking hook is fastened to the positioning frame.

[0007] As a further optimization of this utility model, the lock also includes a mounting plate fixed to the inside of the vehicle body, and a reset member disposed between the mounting plate and the lock hook.

[0008] As a further optimization of this utility model, the second lock includes a lock body fixed to the protective plate, a lock cylinder rotatably disposed inside the lock body, and a locking plate fixed to one end of the lock cylinder.

[0009] As a further optimization of this utility model, a baffle is provided at the bottom of the hand hole, and when the second lock is locked with the protective plate, the protective plate overlaps the baffle.

[0010] As a further optimization of this utility model, the end of the unlocking handle away from the hand hole is fixedly connected to the lock hook. When the lock hook is tilted and separated from the positioning frame, the end of the unlocking handle away from the lock hook is located above the hand hole.

[0011] As a further optimization of this utility model, the unlocking lock also includes a stop member for positioning the unlocking handle, the stop member being disposed between the unlocking handle and the hand hole.

[0012] As a further optimization of this utility model, the stop member includes a retaining plate and a bracket fixed to the top of the retaining plate.

[0013] As a further optimization of this utility model, the bracket is provided with a positioning groove corresponding to the unlocking handle at an angle, and both sides of the hand hole are provided with a slot corresponding to the card plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] When the hood is closed, the locking hook of the first lock and the positioning frame lock the hood. At this time, the unlocking handle is below the hand hole of the cover plate. The unlocking handle will not interfere with the driver's actions. The second lock locks the protective plate to the cover plate and closes the hand hole, so that the unlocking handle is in an inoperable state before the protective plate is opened. This prevents foreign objects from entering the forklift body, avoids impact on the unlocking handle, and prevents the unlocking handle from being accidentally triggered, thus eliminating the safety hazard of the hood being opened accidentally.

[0016] This utility model provides a stop at the handhole to support and position the unlocking handle after it is pulled up. At this time, the unlocking handle is fixed in the positioning groove of the bracket. The stop can restrict the reset of the lock hook, prevent the machine cover from being difficult to open due to the swing of the lock hook, and improve the convenience of opening the machine cover when using this unlocking lock.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example

[0026] Please see Figure 1 and Figure 2 This embodiment relates to a forklift hood unlocking lock, which is adapted to a forklift body B equipped with a hood C and a cover plate P. The rear top of the hood C is hinged to the forklift body B, and the cover plate P is fixedly disposed on the front top of the body B, with the hood C located on the rear top of the body B. The unlocking lock includes a lock 1 disposed inside the body B for locking the hood C, the lock 1 including a lock hook 11 and an unlocking handle 12. The lock hook 11 is rotatably disposed inside the body B, and the unlocking handle 12 is fixedly disposed at the lower end of the lock hook 11. The lock 1 also includes a mounting plate 13 fixed inside the body B, and a reset member 14 disposed between the mounting plate 13 and the lock hook 11. A positioning frame 5 is provided inside the hood C, and the other end of the lock hook 11 is fastened to the positioning frame 5. The middle part of the lock hook 11 is rotatably disposed inside the body B by hinge to the mounting plate 13. The reset element 14 is preferably a torsion spring, which is used to make the connection between the locking hook 11 and the positioning frame 5 more secure.

[0027] like Figure 1-4As shown, a handhole 2 is provided on the cover plate P, and the end of the unlocking handle 12 away from the lock hook 11 extends to the handhole 2. When the cover C is closed, the entire unlocking handle 12 is below the handhole 2. A protective plate 3 is hinged to one side of the handhole 2, and a second lock 4 is provided on the protective plate 3. The second lock 4 is used to lock the protective plate 3 so that the protective plate 3 closes the handhole 2 and covers the unlocking handle 12. The second lock 4 includes a lock body 41 fixed to the protective plate 3, a lock cylinder 42 rotatably located inside the lock body 41, and a locking plate 43 fixed to one end of the lock cylinder 42. The lock body 41 passes through the protective plate 3. A baffle 6 is provided at the bottom of the handhole 2. When the second lock 4 locks the protective plate 3, the protective plate 3 overlaps the baffle 6.

[0028] When the hood C is closed, the locking hook 11 engages with the positioning bracket 5. The unlocking handle 12 is positioned below the handhole 2. The protective plate 3 is horizontally positioned to close the handhole 2. The lock is opened with a key corresponding to the lock cylinder 42. After the protective plate 3 closes the handhole 2, the key is inserted into the lock cylinder 42. Then, by rotating the key, the lock cylinder 42 and the locking plate 43 are rotated, causing one end of the locking plate 43 to rotate to the side of the handhole 2. At this point, the locking plate 43 is in contact with the bottom of the cover plate P, restricting the upward rotation of the protective plate 3 and locking it. This prevents foreign objects from entering the vehicle body B, avoids impact to the unlocking handle 12, and prevents premature unlocking of the hood C due to accidental triggering of the locking hook 11.

[0029] Before opening the hood C, insert the key into the lock cylinder 42 and rotate the lock cylinder 42 in the opposite direction to separate the locking plate 43 from the cover plate P. Then, lift the protective plate 3 to make the unlocking handle 12 operable. To open the hood C, pull up the unlocking handle 12 to rotate the lock hook 11, disengaging the lock hook 11 from the positioning bracket 5. This releases the locking effect on the hood C, allowing the forklift's hood C to be opened, thus protecting the unlocking handle 12 and preventing accidental triggering. Alternatively, in some other embodiments, lock 1 may not have a reset member 14; the locking effect of the lock hook 11 can be maintained by the weight of the unlocking handle 12. Lock 4 can also be replaced with other lock structures, as long as the protective plate 3 securely seals the handhole 2 when horizontally positioned. Furthermore, as... Figure 5 As shown, a lock cover 44 is rotatably provided on the top of the lock body 41. The lock cover 44 is used to cover the lock cylinder 42. When not performing locking or unlocking operations, the lock cover 44 is used to seal the lock cylinder 42 to prevent dust and moisture from entering the lock cylinder 42.

[0030] Furthermore, such as Figure 6As shown, in some other embodiments, a stop 7 is also provided. When the stop 7 is positioned between the unlocking handle 12 and the hand hole 2, it can support and position the unlocking handle 12 to open the cover C. It should be noted that the end of the unlocking handle 12 away from the hand hole 2 is fixedly connected to the locking hook 11. When the locking hook 11 is tilted and separated from the positioning bracket 5, the end of the unlocking handle 12 away from the locking hook 11 can rotate to the top of the hand hole 2, thereby facilitating the support and positioning of the unlocking handle 12 by the stop 7.

[0031] Specifically, the stop 7 includes a locking plate 71 and a bracket 72 fixed to the top of the locking plate 71. The bracket 72 has an inclined positioning groove corresponding to the unlocking handle 12, and both sides of the handhole 2 have corresponding slots corresponding to the locking plate 71. In this embodiment, the operator does not need to maintain the force of pulling the unlocking handle 12 with one hand while opening the machine cover C with the other. After pulling up the unlocking handle 12, the two ends of the locking plate 71 are respectively inserted into the two slots of the handhole 2. At this time, the inclined unlocking handle 12 abuts against the positioning groove of the bracket 72, keeping the locking hook 11 in an inclined state, and then the machine cover C is opened. During the process of opening the machine cover C, the operator can avoid the situation where the locking hook 11 interferes with the positioning bracket 5 due to the downward movement of the unlocking handle 12.

[0032] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of this utility model.
