Description

Technical Field

[0001] This utility model belongs to the field of metering equipment installation technology, specifically relating to a hanging metering scale fixing device. Background Technology

[0002] As a key weighing device in industrial production, logistics warehousing, trade settlement and other scenarios, hanging weighing scales mainly measure materials dynamically or statically by suspension. When working, hanging weighing scales are easily affected by external vibration, wind force or swaying during the hoisting process, which can lead to fluctuations or deviations in weighing data. The performance of its fixing device directly affects the weighing accuracy, equipment stability and service life.

[0003] According to the public announcement (CN212082582U), a hanging weighing scale fixing device is disclosed. This technology discloses "a technical solution including a weighing sensor and a weighing box, with the weighing box located below the weighing sensor, and an anti-impact connection mechanism between the weighing box and the weighing sensor. The upper end of the anti-impact connection mechanism is fixedly connected to the weighing sensor, and the lower end of the anti-impact connection mechanism is fixedly connected to the weighing box, which has the technical effect of effectively improving the measurement accuracy of the weighing sensor."

[0004] In this existing design, the fixing device is manually installed by bolts. The integration between the fixing device and the main body of the weighing scale is high and it cannot be replaced independently. If a component is damaged, the entire device must be disassembled, resulting in low maintenance efficiency. If other parts are damaged due to improper operation, the maintenance cost can be further increased, leading to high maintenance costs. Furthermore, frequent disassembly causes the positioning reference of the fixing device to shift, which increases the weighing error after replacing the equipment and thus affects the weighing accuracy of the equipment.

[0005] Therefore, a hanging weighing scale fixing device is designed to solve the above problems. Utility Model Content

[0026] 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 scope of protection of the present utility model. Embodiment 1

[0027] like Figure 1 As shown;

[0028] A hanging weighing scale fixing device includes a weighing sensor 1 and a weighing box 2 disposed on the lower surface of the weighing sensor 1. An anti-impact connection mechanism 3 is provided between the weighing sensor 1 and the weighing box 2.

[0029] In this implementation scheme: In the prior art, the anti-impact connection mechanism 3 is used to complete the weighing operation. For the specific working principle of the anti-impact connection mechanism 3, please refer to the technology disclosed in "CN212082582U discloses a hanging weighing scale fixing device". This technology discloses that "an anti-impact connection mechanism is provided between the weighing sensor and the weighing box, which effectively reduces the impact force on the weighing sensor due to shaking during the weighing process. Through the cross connector and the upper and lower joint bearings, the impact of the weighing box shaking on the weighing sensor in the horizontal direction can be reduced. The upper threaded rod is threadedly connected to the weighing sensor, providing good fixation. Simultaneously, the threaded connection can..." "To reduce the rotational effect caused by the shaking of the weighing box," however, in this existing design, the fixing device is manually installed by bolts, and the high degree of integration between the fixing device and the weighing body makes it impossible to replace independently. If a component is damaged, the entire device must be disassembled, resulting in low maintenance efficiency. If other parts are damaged due to improper operation, the maintenance cost can be further increased, leading to high maintenance costs. Furthermore, frequent disassembly causes the positioning reference of the fixing device to shift, and the weighing error increases after replacing the equipment, thus affecting the weighing accuracy of the equipment. Considering the usage, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a quick disassembly and assembly component 4 and a multi-stage shock absorption suspension component 5 are added to this application.

[0030] Furthermore:

[0031] like Figures 1 to 3 As shown:

[0032] In conjunction with the above: a hanging weighing scale fixing device further includes a quick-release assembly 4 and a multi-stage shock-absorbing suspension assembly 5 disposed on the surface of the anti-impact connection mechanism 3;

[0033] The quick-release assembly 4 includes a connecting seat 41 fixedly connected to the top of the anti-impact connecting mechanism 3. The surface of the metering sensor 1 has a mounting groove 42 that mates with the connecting seat 41. An electric adjustment push rod 43 is mounted on the surface of the connecting seat 41. A slider 44 is slidably connected to the surface of the metering sensor 1. A first connecting plate 45 is symmetrically rotatably connected to one end of the slider 44. A sliding groove 46 that mates with the first connecting plate 45 is opened on the surface of the metering sensor 1. The end of the slider 44 away from the first connecting plate 45 is fixedly connected to the top of the electric adjustment push rod 43. A second connecting plate 47 is symmetrically slidably connected to the surface of the metering sensor 1. The end of the first connecting plate 45 away from the slider 44 is rotatably connected to the second connecting plate 47. A retaining plate 48 is fixedly connected to the end of the second connecting plate 47 away from the first connecting plate 45.

[0034] In this implementation scheme: Because the surface of the metering sensor 1 has a mounting groove 42 that mates with the connecting seat 41, after the connecting seat 41 is inserted into the mounting groove 42 of the metering sensor 1, the electric adjusting push rod 43 is activated to push the slider 44 to slide inside the metering sensor 1. Since the slider 44 is hinged to the second connecting plate 47 via the first connecting plate 45, when the slider 44 moves...

[0035] The first connecting plate 45 rotates and slides along the track of the slide groove 46 with its hinge point with the slider 44 as the axis. This movement of the first connecting plate 45 drives the second connecting plate 47 to slide on the surface of the metering sensor 1 through the hinge structure, thereby driving the locking plate 48 to achieve precise opening and closing action, so that the locking plate 48 extends outward along the predetermined track to the connecting seat 41 and locks into the groove on the surface of the connecting seat 41. The electric adjusting push rod 43 can be operated in reverse to separate the plates. The locking plate 48 driven by the electric push rod achieves one-click locking, which greatly reduces the installation time.

[0036] Furthermore:

[0037] In an optional embodiment, the side of the card plate 48 away from the second connecting plate 47 has an arc surface that matches the inner surface of the connecting seat 41.

[0038] In this embodiment, the arc surface of the card plate 48 on the side away from the second connecting plate 47 is in contact with the inner surface of the connecting seat 41. When the card plate 48 is extended, the arc surface structure provides a progressive locking force to ensure that the connecting seat 41 and the metering sensor 1 have no gap contact. The arc surface design makes the contact stress distribution more uniform, reduces the local wear rate, and enhances the vibration resistance to avoid the risk of loosening caused by vibration.

[0039] Furthermore:

[0040] In an optional embodiment, a rubber pad is fixedly connected to the side of the card plate 48 away from the second connecting plate 47.

[0041] In this embodiment: when the card plate 48 contacts the connecting seat 41, the rubber pad undergoes elastic deformation, filling the tiny gaps and increasing the coefficient of friction between the card plate 48 and the connecting seat 41, further preventing loosening. At the same time, the rubber pad provides a buffering effect, preventing direct metal friction damage and extending the service life of the equipment.

[0042] Furthermore:

[0043] like Figure 4 and Figure 5 As shown:

[0044] In an optional embodiment, the groove 46 is Z-shaped.

[0045] In this embodiment, the Z-shaped groove 46 fits the first connecting plate 45 which is symmetrically arranged vertically, ensuring that the first connecting plate 45 slides along the correct trajectory in the horizontal direction, preventing the first connecting plate 45 from deviating from the predetermined trajectory, and ensuring the reliability of the quick assembly / disassembly component 4.

[0046] Furthermore:

[0047] like Figure 3 As shown:

[0048] In an optional embodiment, a locking block 49 is symmetrically fixedly connected to the surface of the connecting base 41, and an L-shaped slot 410 that mates with the locking block 49 is opened on the surface of the metering sensor 1.

[0049] In this embodiment: after the locking block 49 of the connecting seat 41 is inserted into the L-shaped slot 410 of the metering sensor 1, it needs to be rotated a certain angle along the L-shaped path to complete the positioning. At this time, the locking block 49 is locked at the corner of the L-shaped slot, forming a mechanical anti-rotation structure.

[0050] Furthermore:

[0051] like Figure 6 As shown:

[0052] In an optional embodiment, the multi-stage shock absorption suspension assembly 5 includes a hydraulic damper 51, the two ends of which are fixedly connected to the metering box 2 and the anti-impact connection mechanism 3, respectively.

[0053] In this embodiment: when the metering box 2 is subjected to external vibration, the vibration energy is absorbed by the damping effect of the hydraulic oil, the system vibration is suppressed, the impact of vibration on the weighing sensor is reduced, and the service life of the equipment is extended.

[0054] Furthermore:

[0055] like Figure 6 As shown:

[0056] In an optional embodiment, a metal bellows 52 is fitted onto the surface of the hydraulic damper 51, and the two ends of the metal bellows 52 are fixedly connected to the metering box 2 and the anti-impact connection mechanism 3, respectively.

[0057] In this embodiment, the metal bellows 52 is sleeved on the outside of the hydraulic damper 51. It expands and contracts with the damper, which can prevent hydraulic oil leakage and adapt to the length changes of the hydraulic damper 51 during expansion and contraction. It can also isolate external dust and corrosive media and protect the surface of the hydraulic damper 51.

[0058] Furthermore:

[0059] like Figure 6 As shown:

[0060] In an optional embodiment, an elastic support seat 53 is provided between the hydraulic damper 51 and the metal bellows 52, and the two ends of the elastic support seat 53 are fixedly connected to the metering box 2 and the anti-impact connection mechanism 3, respectively.

[0061] In this embodiment, the elastic support seat 53 is a butterfly spring assembly, which can provide internal support for the metal bellows 52 to prevent it from collapsing or deforming under negative pressure or external force. At the same time, it assists the hydraulic damper 51 in absorbing radial vibration and improving the dynamic characteristics of the system.

[0062] Working principle: Align the connecting seat 41 with the mounting slot 42 of the metering sensor 1, so that the locking block 49 on the surface of the connecting seat 41 is embedded into the L-shaped locking slot 410. Rotate a certain angle along the L-shaped path to complete the initial positioning. Activate the electric adjusting push rod 43. The push rod extends and pushes the slider 44 to slide on the surface of the metering sensor 1. The slider 44 drives the second connecting plate 47 to move through the hinged first connecting plate 45. The first connecting plate 45 rotates and slides along the Z-shaped sliding groove 46 with the hinge point as the axis, guiding the second connecting plate 47 to extend outward along a predetermined trajectory. The second connecting plate 47 drives the locking plate 48 to engage with the groove of the connecting seat 41. The arc surface of the locking plate 48 fits against the inner surface of the connecting seat 41, and the rubber pad fills the gap to achieve locking. When disassembly is required, the electric adjusting push rod 43 retracts in the opposite direction, driving the slider 44 to move. 4. Reset: The locking plate 48 disengages from the connecting seat 41. Reverse rotation of the connecting seat 41 causes the locking block 49 to disengage from the L-shaped slot 410, thus separating the metering sensor 1 from the connecting seat 41. The tool-free disassembly and assembly design reduces maintenance difficulty, allowing staff to quickly disassemble, inspect, or replace components, reducing downtime and maintenance costs. When the metering box 2 vibrates under external force, the piston inside the hydraulic damper 51 moves and squeezes the hydraulic oil, generating damping force through the throttling orifice, quickly consuming vibration energy and stabilizing the metering box 2. The metal bellows 52 expands and contracts with the hydraulic damper 51, compensating for axial and angular displacements and isolating external dust, water vapor, and other media. The elastic support seat 53 supports the inner wall of the metal bellows 52, preventing it from collapsing due to negative pressure or vibration, while also assisting in absorbing radial vibration and improving system stability.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
