[0002] Forklifts are core equipment in logistics handling and warehousing operations, and their load-bearing capacity directly affects operational safety and efficiency. In actual use, overloading or uneven stress can lead to equipment damage, cargo tipping, and even safety accidents. Therefore, real-time and accurate detection of forklift load-bearing capacity is crucial for ensuring operational safety, extending equipment life, and optimizing load management. However, traditional detection methods often rely on manual experience or simple mechanical indicators, failing to achieve dynamic monitoring and data feedback. This forklift load-bearing capacity detection device is specifically designed to solve these problems and is suitable for forklifts in warehousing, logistics, manufacturing, and port scenarios that frequently handle heavy objects, providing them with real-time load-bearing capacity monitoring and early warning functions.

[0003] Currently, most forklift load capacity testing devices on the market use a combination of fixed sensors and mechanical structures. While this type of structure can achieve basic testing, it has significant drawbacks. The sensors and signal processors are fixed together with bolts, requiring specialized tools for each maintenance or replacement. This process is cumbersome, time-consuming, and labor-intensive. Frequent bolt disassembly can lead to thread wear or component deformation, and long-term use may cause loosening of the installation, affecting testing accuracy. These shortcomings result in insufficient applicability of traditional testing devices, necessitating a new integrated design that allows for quick disassembly to improve the ease of operation of forklift load capacity testing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a forklift load capacity detection device, which aims to improve problems such as low replacement efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forklift load capacity detection device, including a pressure sensor, a signal processor disposed above the pressure sensor, a quick-release assembly disposed inside the pressure sensor, and a connecting assembly disposed on the upper surface of the signal processor;

[0006] The quick-release assembly includes a housing, which is disposed inside the pressure sensor and the signal processor. A shaft is slidably connected inside the housing, and a handle is fixedly connected to one end of the shaft. A groove is formed inside the shaft. A ball bearing is disposed inside the housing and is disposed inside the pressure sensor.

[0007] Furthermore, the connection assembly includes a female connector, one end of which is fixedly connected to the inside of the signal processor, and the other end of which is provided with a male connector. An inner shell is fixedly connected to the outer wall of the male connector. A spring three is sleeved on the outer wall of the inner shell, and a shell sleeve is sleeved on the outer wall of the inner shell. A plurality of ball bearings two are provided inside the inner shell, and the plurality of ball bearings two are disposed inside the shell sleeve.

[0008] Furthermore, a cable is fixedly connected to one end of the male connector, and the other end of the cable is fixedly connected to the upper surface of the signal processor.

[0009] Furthermore, a spring one is sleeved on the outer wall of the shaft, a limit ring is fixedly connected to the outer wall of the shaft, and a spring two is sleeved on the outer wall of the shaft.

[0010] Furthermore, a handle is rotatably connected to the upper surface of the pressure sensor, and a sliding rod is slidably connected inside the handle. The outer wall of the sliding rod is slidably connected inside the pressure sensor.

[0011] Furthermore, the pressure sensor has a sensor output port fixedly connected to its outer wall, and the signal processor has a processor input port fixedly connected to its outer wall. One end of the sensor output port is located inside the processor input port.

[0012] Furthermore, the pressure sensor has a groove inside, which allows the pressure sensor to be mounted on the forklift mast.

[0013] Furthermore, a protrusion is fixedly connected inside the pressure sensor, and the protrusion can be connected to the fork.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the forklift load capacity detection device significantly improves the disassembly and assembly efficiency and maintenance convenience of the pressure sensor and signal processor through the mechanical linkage and elastic reset design of the quick-release components. The sliding fit between the lever and the shaft, combined with the locking mechanism of the groove and the ball, allows the user to complete the installation or removal of the pressure sensor with just one hand, without the need for tools. The bidirectional spring sleeved on the outer wall of the shaft provides elastic support and automatically resets to the initial position after disassembly, preventing the loss of parts. The limit ring precisely restricts the shaft stroke, ensuring that the spring remains stable even under vibration. There is no risk of loosening during long-term use, which greatly reduces maintenance costs and improves equipment reliability.

[0016] In this invention, the forklift load capacity detection device adopts a multi-point elastic contact and anti-vibration protection design to ensure the continuity and reliability of signal transmission. The male and female connectors form multi-point elastic contact through the synergistic action of balls and springs, which can maintain a stable electrical connection even under high-frequency vibration conditions of the forklift, effectively avoiding instantaneous disconnection or signal interference. The sleeve fitted on the outer wall of the inner shell can slide with the inner shell and compress the spring, buffering external impacts and cable bending stress, significantly reducing cable wear rate and extending the service life of the signal transmission system. Through the above design, the device can still accurately collect data in complex operating environments, providing an efficient and durable solution for forklift load capacity monitoring.

[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] Reference Figures 1-4This utility model provides an embodiment of a forklift load-bearing capacity detection device, including a pressure sensor 1, a signal processor 2 disposed above the pressure sensor 1, a quick-release assembly disposed inside the pressure sensor 1, and a connecting assembly disposed on the upper surface of the signal processor 2; the quick-release assembly includes a housing 6, which is disposed inside the pressure sensor 1 and the signal processor 2, and a shaft 7 is slidably connected inside the housing 6, with a handle 8 fixedly connected to one end of the shaft 7, a groove 12 formed inside the shaft 7, and a ball bearing 13 disposed inside the housing 6 and inside the pressure sensor 1; the handle 8 slides in cooperation with the shaft 7. The movement, achieved by pressing the lever 8, displaces the shaft 7, causing the groove 12 to disengage from the ball bearing 13, releasing the lock between the pressure sensor 1 and the signal processor 2, thus achieving rapid disassembly and significantly shortening maintenance time. A spring 10 is fitted onto the outer wall of the shaft 7, and a limit ring 9 is fixedly connected to the outer wall. A second spring 11 is also fitted onto the outer wall of the shaft 7. Springs 10 and 11 provide bidirectional elastic restoring force. Spring 10 cushions the impact of disassembly, while spring 11 pushes the shaft 7 back to its initial position, preventing component loss and ensuring structural stability after disassembly and assembly. The limit ring 9 restricts the stroke of the shaft 7, precisely controlling the spring's movement. The spring compression range prevents excessive displacement from causing structural damage and ensures the reliability of the quick-release assembly during long-term use. One end of the male connector 14 is fixedly connected to a cable 5, and the other end of the cable 5 is fixedly connected to the upper surface of the signal processor 2. A handle 3 is rotatably connected to the upper surface of the pressure sensor 1. A sliding rod 4 is slidably connected inside the handle 3, and its outer wall is slidably connected to the inside of the pressure sensor 1. The handle 3 drives the sliding rod 4 to press down and lock it in place. When the handle 3 is rotated, the sliding rod 4 slides along the inside of the pressure sensor 1, locking the sensor to the frame, uniformly transmitting pressure, and improving detection accuracy. A sensor output port 22 is fixedly connected to the outer wall of the pressure sensor 1. The signal processor... The outer wall is fixedly connected to a processor input port 23. One end of the sensor output port 22 is located inside the processor input port 23. The pressure sensor 1 has a slide groove 20 inside. The slide groove 20 can install the pressure sensor 1 on the forklift mast. The slide groove 20 matches the forklift mast for installation. The pressure sensor 1 is quickly positioned and fixed to the forklift mast through the slide groove 20, which simplifies the installation process and reduces the difficulty of manual adjustment. The pressure sensor 1 has a protrusion 21 fixedly connected inside. The protrusion 21 can be connected to the fork. The standardized interface design is compatible with multiple fork models, ensuring a stable force transmission path and avoiding detection errors caused by interface mismatch.

[0026] Reference Figure 1 and Figure 5The connection assembly includes a female connector 19, one end of which is fixedly connected to the inside of the signal processor 2. The other end of the female connector 19 has a male connector 14. An inner shell 15 is fixedly connected to the outer wall of the male connector 14. A spring 16 is fitted onto the outer wall of the inner shell 15, and a housing 17 is fitted onto the outer wall of the inner shell 15. Multiple ball bearings 18 are disposed inside the inner shell 15 and inside the housing 17. The male connector 14 inserts into the female connector 19 to form multi-point elastic contact. The ball bearings 18 are pressed by the spring 16 and embedded into the grooves on the inner wall of the female connector 19, achieving a self-locking electrical connection and resisting fork penetration. To mitigate the risk of loosening due to vehicle vibration, the housing 17 is fitted onto the outer wall of the inner housing 15. When the spring 3 16 is compressed, the housing 17 slides, buffering the bending stress of the cable 5 and external impacts, reducing cable wear, and extending service life. The ball 2 18 rolls against the inner wall of the female connector 19, reducing insertion and extraction resistance. At the same time, the spring 3 16 elastically compensates for tolerance gaps, adapting to different insertion depths and ensuring continuous and stable signal transmission. The sensor output port 22 is directly connected to the processor input port 23, achieving delay-free signal transmission through the cable 5, avoiding interference from intermediate links, and ensuring the real-time performance and accuracy of the load-bearing capacity data.

[0027] Working principle: When the lever 8 is pushed, the shaft 7 slides along the housing 6, the groove 12 engages with the ball 13 to lock the pressure sensor 1 and the signal processor 2, and the spring 10 and the spring 211 push the shaft to reset. When operating in the reverse direction, the lever 8 is pulled, so that the ball 13 falls into the groove 12, and the housing 6 is released from engagement. Disassembly and assembly can be completed without tools. The design of the slide 20 allows the pressure sensor 1 to be quickly and easily slidably installed on the forklift mast. The standardized interface of the protrusion 21 is compatible with multiple models of forks. Rotating the eccentric wheel handle 3 can press down the sliding rod 4 to lock the pressure sensor 1 on the forklift mast, ensuring uniform pressure transmission. The signal processor 2 analyzes the pressure data in real time and feeds back the load status through an external display screen or wireless terminal, which is convenient for the operator to dynamically adjust the operation.

[0028] When the male connector 14 is inserted into the female connector 19, the second ball 18 is pressed into the groove by the third spring 16, forming a multi-point elastic contact. The sleeve 17 is fitted on the outer wall of the inner shell 15 and can slide with the inner shell 15 and compress the third spring 16, buffering external impacts and bending stress of the cable 5, significantly reducing cable wear, while limiting the second ball 18 to prevent displacement. The sensor output port 22 and the processor input port 23 are directly connected by a cable to ensure that the pressure signal is transmitted to the signal processor 2 without delay.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
