[0002] In modern logistics and industrial production, forklifts are indispensable handling equipment, and their performance directly affects operational efficiency and safety. The forklift frame, as the core load-bearing component of the forklift, undertakes the crucial functions of picking up and moving goods. Its structural design and technological development have always been closely linked to industry needs. Early forklift frame technology mainly adopted simple steel structure designs to meet basic cargo picking requirements.

[0003] Existing forklift frames are usually of fixed size, which limits the scope of use of forklifts. In some special handling scenarios, such as when it is necessary to handle extra-long goods, fixed forklift frames cannot be adjusted to adapt to the size of the goods by adjusting their own structure. Only additional auxiliary equipment or special handling methods can be used, which not only increases the complexity of handling, but may also affect the safety of handling. Therefore, those skilled in the art provide an adjustable forklift frame to solve the problems mentioned in the background art. Utility Model Content

Adjustment components for adjusting the lateral length of the first forks are provided between the two sets of first forks and the first support plates, and expansion components for expanding the area are provided between the two sets of first support plates and the outer wall of the first forks.

[0006] As a preferred embodiment of the above technical solution, the adjustment assembly includes two sets of fixed seats symmetrically arranged on the side surface of the connecting frame facing the forklift. A first gear is rotatably connected to each of the two sets of fixed seats. Slide grooves are formed in the fixed seats and the first support plate below each of the two sets of first gears. Slide plates are slidably connected to each of the two sets of slide plates. First forks are fixedly connected to the side surface of each of the two sets of slide plates facing away from the connecting frame. First racks are fixedly connected to the side surface of each of the two sets of slide plates facing the first gear, and the first racks mesh with the first gear. A second gear is rotatably connected to the fixed seat in the set facing away from the connecting frame, and the second gear passes through the fixed seat and is fixedly connected to one end of the first gear. A movable compartment is fixedly connected to the surface of the fixed seat below the second gear. A lead screw is rotatably connected to the movable compartment, and a transmission block is threaded onto the lead screw. A second rack is fixedly connected to the top surface of the transmission block. A drive motor is fixedly connected to the outer wall of the movable compartment on the side facing away from the first support plate, and the output end of the drive motor passes through the movable compartment and is fixedly connected to one end of the lead screw.

[0007] As a preferred embodiment of the above technical solution, the slide plate is C-shaped, and the portion of the slide plate inserted into the groove is designed to be rectangular and adapted to the groove.

[0008] As a preferred embodiment of the above technical solution, the extension component includes two sets of first positioning grooves symmetrically formed on the outer walls of corresponding ends of two sets of first support plates; second positioning grooves symmetrically formed on the outer walls of corresponding ends of the two sets of first forks; positioning posts slidably connected within both sets of first and second positioning grooves; second support plates fixedly connected to the outer surfaces of the positioning posts in both sets of first positioning grooves; second forks fixedly connected to the outer surfaces of the positioning posts in both sets of second positioning grooves; and two sets of sliding rods symmetrically arranged on the outer walls of the two sets of second forks facing the second support plates. Furthermore, the other end of each slide rod slides within the second support plate. Guide grooves are provided on the surfaces of the first forks and the first support plate corresponding to the two sets of second forks and the second support plate, respectively. Threaded rods are slidably connected within the guide grooves of the two sets of first forks and the first support plate. The outer end surfaces of the threaded rods of the two sets of first forks and the first support plate are fixedly connected to the outer walls of the two sets of second support plates and the second forks, respectively. Limiting grooves are provided on the outer walls of the opposite ends of the two sets of first support plates and the first forks, and the limiting grooves are connected to the guide grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a drive motor to rotate a lead screw within a movable compartment, which in turn causes a transmission block to move a second rack. The second rack then drives a first gear to rotate within a fixed seat via a second gear, which in turn drives a sliding plate to slide within a groove via the first rack. This allows the sliding plate to adjust the lateral length of the first fork, and enables the first support plate and the first fork to be length-adjusted according to different sized goods. This improves the adaptability and versatility of the forklift frame while reducing the complexity of handling goods.

[0013] 2. This utility model uses a second support plate and a second fork to drive the positioning pins to be inserted into the first positioning groove and the second positioning groove respectively. At the same time, the threaded rods on the second fork and the second support plate slide into the guide groove simultaneously. Then, by rotating the self-locking nut on the threaded rod, the self-locking nut rotates through the thread on the threaded rod and squeezes the inner wall of the limiting groove, thereby achieving the purpose of adding the second fork and the second support plate to the first support plate and the first fork. This changes the width of the first fork and the first support plate, enabling the forklift frame to handle goods of different widths. The increased load-bearing area also improves the safety of handling goods. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: an adjustable forklift frame, including a forklift 1, a connecting frame 2 is provided on the right end surface of the forklift 1, two sets of first support plates 3 are symmetrically arranged on the connecting frame 2, and first forks 4 are attached to the side of the two sets of first support plates 3 away from the forklift 1. Adjustment components 5 for adjusting the lateral length of the first forks 4 are provided between the two sets of first forks 4 and the first support plates 3, and expansion components 6 for expanding the area are provided on the outer walls of the two sets of first support plates 3 and the first forks 4.

[0023] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 as well as Figure 5 As shown, the adjusting assembly 5 includes two sets of fixed seats 51 symmetrically arranged on the side surface of the connecting frame 2 facing the forklift 1. A first gear 52 is rotatably connected to each of the two sets of fixed seats 51. Slide grooves 53 are provided in both the fixed seats 51 below the two sets of first gears 52 and in the first support plate 3. Slide plates 54 are slidably connected to each of the two sets of slide plates 53. A first fork 4 is fixedly connected to the side surface of each of the two sets of slide plates 54 facing away from the connecting frame 2. A first rack 55 is fixedly connected to the side surface of each of the two sets of slide plates 54 facing the first gear 52, and the first rack 55 meshes with the first gear 52. A second gear 56 is rotatably connected inside a set of fixed seats 51 of the frame 2. The second gear 56 passes through the fixed seats 51 and is fixedly connected to one end of the first gear 52. A movable chamber 57 is fixedly connected to the surface of the fixed seats 51 below the second gear 56. A lead screw 58 is rotatably connected inside the movable chamber 57. A transmission block 59 is threaded onto the lead screw 58. A second rack 510 is fixedly connected to the top surface of the transmission block 59. A drive motor 511 is fixedly connected to the outer wall of the movable chamber 57 on the side away from the first support plate 3. The output end of the drive motor 511 passes through the movable chamber 57 and is fixedly connected to one end of the lead screw 58.

[0024] Specifically, the drive motor 511 drives the lead screw 58 to rotate within the movable compartment 57, and the transmission block 59 synchronously drives the second rack 510 to move. The second rack 510 then drives the first gear 52 to rotate within the fixed seat 51 via the second gear 56. The first gear 52 then drives the slide plate 54 to slide within the slide groove 53 via the first rack 55. This allows the slide plate 54 to adjust the lateral length of the first fork 4, and enables the first support plate 3 and the first fork 4 to be length-adjusted according to different sizes of goods. This improves the adaptability and versatility of the forklift frame while reducing the complexity of goods handling.

[0025] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, the slide plate 54 has a C-shaped design, and the part of the slide plate 54 that inserts into the slide groove 53 is designed to fit the slide groove 53 in a rectangular shape.

[0026] Specifically, the sliding plate 54 can slide synchronously in the two sets of sliding grooves 53 under the action of the first gear 52 and the first rack 55, thereby improving the consistency of the sliding of the first fork 4 in the first support plate 3, while ensuring the stability of the sliding, preventing the sliding plate 54 from becoming loose in the sliding groove 53, which would affect the handling stability of the first fork 4.

[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 as well as Figure 4 As shown, the extension component 6 includes two sets of first positioning grooves 61 symmetrically opened on the outer walls of the corresponding ends of the two sets of first support plates 3, and two sets of second positioning grooves 62 symmetrically opened on the outer walls of the corresponding ends of the two sets of first forks 4. Positioning posts 63 are slidably connected to both the first positioning grooves 61 and the second positioning grooves 62. Second support plates 64 are fixedly connected to the outer surfaces of the positioning posts 63 in the two sets of first positioning grooves 61. Second forks 65 are fixedly connected to the outer surfaces of the positioning posts 63 in the two sets of second positioning grooves 62. Two sets of sliding rods 66 are symmetrically arranged on the outer walls of the two sets of second forks 65 facing the second support plate 64, and the other ends of the sliding rods 66... All of them slide within the second support plate 64. The two sets of second forks 65 and the second support plate 64 respectively have guide grooves 67 on their corresponding surfaces of the first forks 4 and the first support plate 3. Threaded rods 68 are slidably connected in the guide grooves 67 of the two sets of first forks 4 and the first support plate 3. The outer end surfaces of the threaded rods 68 of the two sets of first forks 4 and the first support plate 3 are fixedly connected to the outer walls of the two sets of second support plates 64 and the second forks 65, respectively. Limiting grooves 69 are opened on the outer walls of the opposite ends of the two sets of first support plates 3 and the first forks 4, and the limiting grooves 69 are connected to the guide grooves 67. Self-locking nuts 610 are threadedly connected to the four sets of threaded rods 68.

[0028] Specifically, the second support plate 64 and the second fork 65 drive the positioning pin 63 to be inserted into the first positioning groove 61 and the second positioning groove 62 respectively. At the same time, the threaded rod 68 on the second fork 65 and the second support plate 64 slides into the guide groove 67. Then, by rotating the self-locking nut 610 on the threaded rod 68, the self-locking nut 610 rotates through the thread on the threaded rod 68 and squeezes the inner wall of the limiting groove 69, thereby achieving the purpose of installing the second fork 65 and the second support plate 64 onto the first support plate 3 and the first fork 4. This changes the width of the first fork 4 and the first support plate 3, enabling the forklift frame to handle goods of different widths. The increased load-bearing area also improves the safety of handling goods. When the first fork 4 slides in the first support plate 3, it also drives the second fork 65, causing the second fork 65 to drive the sliding rod 66 to slide in the second support plate 64.

[0029] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the second fork 65 is configured to match the shape of the first fork 4, and the upper and lower surfaces of the extension component 6 are flush with the upper and lower surfaces of the first fork 4.

[0030] Specifically, this implementation allows the second fork 65 to match the first fork 4, resulting in greater stability when handling goods of different widths. It also prevents one side of the second fork 65 from being too high, which could cause the goods to tilt and affect the handling process.

[0031] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the positioning post 63 is cylindrical in shape, and both the first positioning groove 61 and the second positioning groove 62 are provided with through holes that are compatible with the positioning post 63.

[0032] Specifically, this increases the contact area between the positioning post 63 and the first positioning groove 61 and the second positioning groove 62, thereby improving the fit between the first positioning groove 61 and the second positioning groove 62 and the positioning post 63 to achieve the purpose of positioning the second fork 65 and the second support plate 64, thus making it easier for workers to install the second fork 65 and the second support plate 64 onto the first support plate 3 and the first fork 4.

[0033] Working principle: First, start the drive motor 511, which drives the lead screw 58 to rotate in the movable compartment 57. This drives the transmission block 59 to move back and forth in the movable compartment 57, causing the second rack 510 to move synchronously. While the second rack 510 is moving, it drives the first gear 52 to rotate in the fixed seat 51 through the second gear 56. The first gear 52 then acts on the first rack 55, causing the slide plate 54 to slide in the slide groove 53. This achieves the purpose of adjusting the length of the first fork 4, allowing the first support plate 3 and the first fork 4 to be extended and adjusted according to the length of goods of different lengths, thereby increasing the adaptability of the forklift frame.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
