Description

Technical Field

[0001] This utility model relates to the field of electric forklift technology, specifically a multi-functional electric forklift with good braking stability. Background Technology

[0002] Electric forklifts are forklifts that use electricity as their power source. Most of them operate from batteries, converting chemical energy into electrical energy to drive the drive motor and hydraulic system motor, thereby enabling driving and loading / unloading operations.

[0003] The existing Chinese patent publication number CN221217043U, entitled "A Multifunctional Electric Forklift with Good Braking Stability," explicitly states in its abstract that "This utility model discloses a multifunctional electric forklift with good braking stability, including a vehicle body and a cab, the vehicle body and cab being fixedly connected. Movable wheels are fixedly installed at the bottom of the vehicle body. A fork is provided at the front of the vehicle body, and a weighing sensor is fixedly installed at the rear of the fork. An audible and visual alarm light is fixedly installed on the top of the cab. The weighing sensor is electrically connected to the audible and visual alarm light. A support plate is provided at the back of the vehicle body, and a cleaning mechanism is placed on top of the support plate. This utility model, through the provided weighing sensor and alarm, can detect the weight of the forklifted object, preventing deformation and damage to the forklift's fork due to excessive weight. The cleaning mechanism can spray water to reduce dust in the factory workshop. After the cleaning mechanism sprays water to reduce dust, the cleaning brush will clean and scrub the workshop floor as the forklift moves, keeping the workshop clean and tidy."

[0004] However, in this technology, since the load cell is located at the rear end of the fork, the length, width, and shape of the objects being transported are different in actual use. This can easily lead to the objects being transported not being able to reach the rear end of the fork and thus not being able to contact the load cell, meaning that the material cannot be weighed. There is still a possibility that the forklift forks may be deformed or damaged due to the heavy objects being picked up. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional electric forklift with good braking stability to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-functional electric forklift with good braking stability includes a forklift body, a lifting frame, two insert rods, and two extension rods. A weighing sensor is installed inside the lifting frame, and first springs are installed on both sides of the lifting frame to connect to the rear of the insert rods. A weighing component is installed above the weighing sensor, and a connecting component is installed behind the extension rods.

[0008] The weighing assembly includes a sliding frame, on which a sliding plate is slidably disposed, and on both sides of the sliding plate are connected rods;

[0009] The connecting assembly includes a threaded port, and an internal hexagon bolt is provided inside the threaded port. The internal hexagon bolt is threadedly connected to the threaded port, and a clamping assembly is provided above the first spring.

[0010] In a preferred embodiment of this utility model, a contact block is provided at the bottom inner side of the sliding plate, and the contact block is in contact with the weighing sensor.

[0011] In a preferred embodiment of this utility model, a limiting post is provided at the bottom of the internal hex bolt, and a limiting port is provided at the rear of the insertion rod. The limiting post is installed and removed from the limiting port.

[0012] In a preferred embodiment of this utility model, a hexagonal groove is provided on the inner side of the extension rod, and a hexagonal block is slidably disposed inside the hexagonal groove.

[0013] In a preferred embodiment of this utility model, a threaded bolt is provided at the bottom of the hexagonal block, and an internally threaded component is rotatably provided in front of the insertion rod, the internally threaded component being threadedly connected to the threaded bolt.

[0014] In a preferred embodiment of the present invention, the clamping assembly includes a screw thread, a second spring is provided at the bottom of the screw thread, a clamping block is provided at the bottom of the second spring, and an installation rod is movably provided inside the screw thread.

[0015] In a preferred embodiment of this utility model, the bottom of the mounting rod is rotatably connected to the clamping block, and the clamping block is installed and removed from the top of the internal hex bolt.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Beneficial effects: The first spring pushes the insert rod and sliding plate, preventing the contact block from contacting the load cell. When the insert rod is loaded with material, it lowers the insert rod and sliding plate, causing the contact block to contact the load cell. The load cell then weighs the material, and as long as there is material pressing on the insert rod, weighing is achieved, avoiding underweighing. The extension rod is installed by inserting a hexagonal block into a hexagonal slot and rotating the internal threaded part to connect the threaded bolt. Then, by rotating the internal hexagonal bolt at the rear, the limiting post is inserted into the limiting port, thus fixing the rear of the extension rod and completing the installation of the extension rod. This extends the insert rod while still ensuring weighing capability.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-4 This utility model discloses a multi-functional electric forklift with good braking stability, including a forklift body 1, a lifting frame 11, two extension rods 12, and two extension rods 13. The forklift body 1 is the electric forklift, which adopts a dual braking system of hydraulic steering and mechanical parking, electronic control, and an LCD instrument that displays the battery level and fault codes in real time, which can ensure operational safety and thus has good braking stability. The lifting frame 11 is the lifting structure of the forklift, the extension rods 12 are the main body of the forklift, and are used to transport objects. The extension rods 13 are used to extend the extension rods 12, and whether to install the extension rods 13 depends on the actual situation.

[0028] A weighing sensor 2 is installed inside the lifting frame 11. First springs 22 are installed on both sides of the lifting frame 11 to connect to the rear of the insertion rod 12. A weighing assembly is installed above the weighing sensor 2. The weighing assembly includes a sliding frame 14. A sliding plate 21 is slidably installed on the sliding frame 14. The insertion rod 12 is connected to both sides of the sliding plate 21, so that the insertion rod 12 can be raised and lowered to a certain extent. A contact block 23 is installed at the bottom of the inner side of the sliding plate 21. The insertion rod 12 and the sliding plate 21 are pushed by the first spring 22, so that the contact block 23 does not contact the weighing sensor 2. When the insertion rod 12 is loaded with a material, the insertion rod 12 and the sliding plate 21 will descend, so that the contact block 23 will contact the weighing sensor 2. That is, the material is weighed by the weighing sensor 2. Weighing is only required as long as there is material pressing on the insertion rod 12, avoiding the situation of underweighing.

[0029] A connecting assembly is provided at the rear of the extension rod 13. The connecting assembly includes a threaded port 34, inside which is a hexagonal socket bolt 33. The hexagonal socket bolt 33 is threadedly connected to the threaded port 34. A limit post 35 is provided at the bottom of the hexagonal socket bolt 33. A limit port 25 is provided at the rear of the insertion rod 12. The limit post 35 is installed and removed from the limit port 25. A hexagonal groove 3 is provided on the inner side of the extension rod 13. A hexagonal block 31 is slidably disposed inside the hexagonal groove 3. A threaded bolt 32 is provided at the bottom of the hexagonal block 31. The insertion rod 1... 2. An internally threaded part 24 is rotatably provided at the front. The internally threaded part 24 is threadedly connected to the threaded bolt 32. That is, the hexagonal block 31 is inserted into the hexagonal slot 3, so that the threaded bolt 32 is at the bottom, and the internally threaded part 24 is connected to the threaded bolt 32. That is, by rotating the internally threaded part 24 to connect the threaded bolt 32, the extension rod 13 is installed. Then, by rotating the internal hexagonal bolt 33 at the rear, the limiting post 35 is inserted into the limiting port 25, that is, the extension rod 13 is fixed at the rear, thus completing the installation of the extension rod 13.

[0030] A clamping assembly is provided above the first spring 22. The clamping assembly includes a screw hole 4, a second spring 41 is provided at the bottom of the screw hole 4, and a clamping block 43 is provided at the bottom of the second spring 41. An installation rod 42 is movably provided inside the screw hole 4. The installation rod 42 can rotate and slide. The bottom of the installation rod 42 is locked in the clamping block 43 and rotates. The clamping block 43 is detached from the top of the hexagonal socket bolt 33. A threaded head 44 is provided on the installation rod 42. The threaded head 44 is threadedly connected to the screw hole 4. That is, by pushing the clamping block 43 through the second spring 41, the clamping block 43 is inserted into the hexagonal socket bolt 33, so that the hexagonal socket bolt 33 cannot rotate, thus preventing the hexagonal socket bolt 33 from loosening. By pulling the installation rod 42 and screwing the threaded head 44 into the screw hole 4, the clamping block 43 is removed from the top of the hexagonal socket bolt 33, thus disassembling the hexagonal socket bolt 33.

[0031] The working principle of this utility model is as follows: The first spring 22 pushes the insertion rod 12 and the sliding plate 21, preventing the contact block 23 from contacting the load cell 2. When the insertion rod 12 carries a load, it lowers, causing the contact block 23 to contact the load cell 2, thus allowing the load cell 2 to weigh the material. Weighing is achieved as long as material is pressed against the insertion rod 12, preventing under-weighing. The hexagonal block 31 is inserted into the hexagonal slot 3, ensuring the threaded bolt 32 is at the bottom. Furthermore, the internal threaded part 24 is connected to the threaded bolt 32, that is, by rotating the internal threaded part 24 to connect the threaded bolt 32, the extension rod 13 is installed. Then, by rotating the internal hex bolt 33 at the rear, the limiting post 35 is inserted into the limiting port 25, that is, the extension rod 13 is fixed at the rear, thus completing the installation of the extension rod 13, thereby extending the insertion rod 12. The second spring 41 pushes the clamping block 43, causing the clamping block 43 to be inserted into the internal hex bolt 33, thereby preventing the internal hex bolt 33 from rotating, that is, preventing the internal hex bolt 33 from loosening.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
