Description

Technical Field

[0001] This utility model relates to the field of bracket assembly technology, specifically a forklift bracket assembly with a front-end locking mechanism. Background Technology

[0002] Currently, forklifts are widely used in warehousing, loading and unloading, manufacturing and other scenarios as core equipment in industrial logistics handling.

[0003] Traditional forklift fork structures, such as the forklift bracket disclosed in CN108910783A, are mostly simple horizontal forks. These cannot reliably grip the materials being transported, especially when handling irregularly shaped, palletless, or easily slippery objects, leading to instability and a higher risk of slippage. Some special operations require temporary reinforcement using manual auxiliary structures such as ropes and clips, which is not only inefficient but may also pose safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a forklift support assembly with a front-end locking mechanism. This solves the problem of the inability to reliably clamp the materials being transported, especially when handling irregularly shaped, palletless, or easily slippery objects, which can lead to instability and a high risk of slippage. Some special operations require the manual installation of auxiliary structures, such as ropes or clips, for temporary reinforcement, which is not only inefficient but may also pose safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forklift bracket assembly with a front-end locking mechanism, comprising:

[0006] Mounting plate, one side of which is fixedly connected to a connecting block, and the other side of which is fixedly connected to a surrounding frame;

[0007] An unlocking component, one side of which is fixedly connected to one side of the mounting plate, is used to directly unlock the front latch of the device after it has been latched.

[0008] A locking assembly, one side of which is fixedly connected to one side of an unlocking assembly, is used to stably clamp the material to be clamped.

[0009] Preferably, the unlocking component includes a mounting bracket fixedly connected to the surface of the mounting plate, an unlocking motor fixedly connected to one side of the inner surface of the mounting bracket, a threaded sleeve being threaded onto one end of the output shaft of the unlocking motor, and a synchronous shaft fixedly connected to one end of the threaded sleeve.

[0010] Preferably, a limiting plate is fixedly connected to the surface of the synchronous shaft, a protruding plate is provided on the surface of the synchronous shaft, and a nut is threadedly connected to the surface of the synchronous shaft.

[0011] Preferably, the locking assembly includes an outer ring cover movably connected to one side of the unlocking assembly, the inner wall of the outer ring cover has a groove, and a pawl is fixedly connected to one side of the outer ring cover.

[0012] Preferably, a base block is fixedly connected to the bottom of the inner wall of the enclosure frame, a dovetail groove is provided on the top of the base block, a dovetail block is movably connected to the inner wall of the dovetail groove, and a movable plate is fixedly connected to the bottom of the dovetail block.

[0013] Preferably, a ratchet is fixedly connected to the top of the movable plate, a fork plate is fixedly connected to one side of the movable plate, a spring is fixedly connected to one side of the movable plate, and one end of the spring is fixedly connected to one side of the inner wall of the surrounding frame.

[0014] This utility model provides a forklift bracket assembly with a front-end locking mechanism. Compared with the prior art, it has the following advantages:

[0015] 1. This forklift bracket assembly with a front-end locking mechanism features an electrically driven unlocking component. The unlocking motor rotates the threaded sleeve and synchronous shaft, working in conjunction with a limit plate and a convex plate for precise positioning, enabling rapid switching of the locking state. This design eliminates manual unlocking and allows for remote or automatic control, making it particularly suitable for intelligent warehousing or automated material handling systems. Due to the use of a threaded drive and synchronous linkage structure, this unlocking device not only boasts high response speed and stability but also significantly reduces the burden on operators under high-intensity work conditions. The stepper motor in this structure provides precise rotation, preventing damage to components from excessive rotation, extending equipment lifespan, and improving the reliability and safety of the device.

[0016] 2. This forklift bracket assembly with a front-end locking mechanism achieves secure clamping of transported materials through a linkage design between the outer ring cover and the pawl. The locking assembly has a groove that matches the protrusion in the unlocking assembly, ensuring structural interlocking and positional accuracy during locking and unlocking. More importantly, the pawl engages with the ratchet teeth on the moving plate, achieving a "one-way clamping, two-way anti-slip" function. This means it automatically locks when loaded, preventing items from loosening or falling due to forklift movement or vibration. A spring and damping structure provide clamping rebound force, giving the entire locking system adaptive clamping capability. It can stably fix goods of different sizes, weights, or shapes, greatly improving the safety, reliability, and adaptability of forklift operations. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides two technical solutions:

[0026] Example 1: A forklift bracket assembly with a front-end locking mechanism, comprising:

[0027] Mounting plate 1, with a connecting block 2 fixedly connected to one side of the mounting plate 1. The connecting block 2 is provided with a threaded groove so as to be fixed to external equipment by bolts. A surrounding frame 3 is fixedly connected to the other side of the mounting plate 1. The surrounding frame 3 can effectively isolate dust and debris during external operation. A sealing cover is connected to the front of the surrounding frame 3 by screw threads.

[0028] Unlocking component 4, one side of which is fixedly connected to one side of mounting plate 1, is used to directly unlock the front latch of the device after it is locked.

[0029] The locking assembly 5 is fixedly connected to one side of the unlocking assembly 4. The locking assembly 5 is used to stably clamp the material to be held. The unlocking assembly 4 is electrically driven to unlock, using an unlocking motor 42 to rotate the threaded sleeve 43 and synchronous shaft 44. This, along with the limiting plate 45 and the protruding plate 46, achieves precise positioning and allows for rapid switching of the locking state. This design avoids manual unlocking and enables remote or automatic control, making it particularly suitable for intelligent warehousing or automated handling systems. Due to the use of a threaded drive and synchronous linkage structure, this unlocking device not only has high response speed and stability but also significantly reduces the burden on operators under high-intensity work. The motor in this structure is a stepper motor, which provides precise rotation, preventing damage to components due to excessive rotation, extending equipment lifespan, and improving the reliability and safety of the device.

[0030] Example 2 differs from Example 1 mainly in that: the forklift bracket assembly with front locking mechanism includes an unlocking component 4 comprising a mounting bracket 41 fixedly connected to the surface of mounting plate 1, an unlocking motor 42 fixedly connected to one side of the inner surface of mounting bracket 41, the unlocking motor 42 being a stepper motor with precise and rapid rotation, a threaded sleeve 43 threaded onto one end of the output shaft of unlocking motor 42, an internal thread on the surface of the output shaft of unlocking motor 42, a synchronous shaft 44 fixedly connected to one end of the threaded sleeve 43, a limiting plate 45 fixedly connected to the surface of synchronous shaft 44, one side of the limiting plate 45 being circular, a protruding plate 46 on the surface of synchronous shaft 44, and a nut 47 threadedly connected to the surface of synchronous shaft 44.

[0031] The locking assembly 5 includes an outer ring cover 51 movably connected to one side of the unlocking assembly 4. The inner wall of the outer ring cover 51 has a groove 52, which is adapted to the protrusion 46. A pawl 53 is fixedly connected to one side of the outer ring cover 51. The pawl 53 and the ratchet 58 engage in a one-way engagement. A base block 54 is fixedly connected to the bottom of the inner wall of the surrounding frame 3. A dovetail groove 55 is opened on the top of the base block 54. A dovetail block 56 is movably connected to the inner wall of the dovetail groove 55. A movable plate 57 is fixedly connected to the bottom of the dovetail block 56. A ratchet 58 is fixedly connected to the top of the movable plate 57. Multiple ratchet 58s are evenly arranged. A fork plate 59 is fixedly connected to one side of the movable plate 57. A spring 510 is fixedly connected to one side of the movable plate 57. A damper is provided on the inner wall of the spring 510. One end of the spring 510 is fixedly connected to one side of the inner wall of the surrounding frame 3. The locking assembly 5 achieves a firm clamping of the transported material through the linkage design between the outer ring cover 51 and the pawl 53. The locking assembly has a groove 52 that matches the protrusion 46 in the unlocking assembly, ensuring structural interlocking and positional accuracy during locking and unlocking. More importantly, the pawl 53 engages with the ratchet 58 on the moving plate 57, achieving a "one-way clamping, two-way anti-slip" function. This means it automatically locks when loaded, preventing items from loosening or falling due to forklift movement or vibration. The spring 510 and damping structure provide clamping rebound force, giving the entire locking system adaptive clamping capability. This allows for stable fixation of goods of different sizes, weights, or shapes, greatly improving the safety, reliability, and adaptability of forklift operations.

[0032] The fork plate 59 can be replaced with a clamping plate with a larger contact area. The pawl 53 is a permanent magnet, and the ratchet 58 is made of iron. The pawl 53 and the ratchet 58 engage in one direction. The unlocking motor 42 is controlled by a control button. The operation process is simple and it has overload protection.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the mounting plate 1 is fixedly connected to the external equipment. When clamping materials, the fork plate 59 is aligned with the material. As the mounting plate 1 moves forward, the material pushes the fork plate 59 to both sides of the mounting plate 1, simultaneously moving the moving plate 57. At the same time, the dovetail block 56 at the bottom of the moving plate 57 slides along the dovetail groove 55 in the base block 54, and the ratchet 58 slides. During movement, the pawl 53 slides past the tooth tip and does not engage, while the pawl 53 prevents the ratchet 58 from moving in the opposite direction, keeping it stationary. The ratchet 58 is locked and fixed by the pawl 53, and the spring 510 is compressed. After the material is clamped and locked, it is transferred. After the transfer is completed, the unlocking motor 42 on the surface of the mounting frame 41 is activated, which drives the synchronous shaft 44, the limit plate 45, and the protruding plate 46 through the screw sleeve 43 to rotate the outer ring cover 51. The pawl 53 separates from the ratchet 58, and the spring 510 pushes the moving plate 57 and the ratchet 58 to reset. When the pawl 53 is damaged and requires maintenance, rotate the nut 47 to separate the nut 47 from the synchronous shaft 44, and pull out the outer ring cover 51 to separate the outer ring cover 51 from the synchronous shaft 44, thereby disassembling and maintaining the pawl 53 as a whole. After the device maintenance is completed, restore it completely.
