[0036] The mounting plate 2 is connected to an external structure (such as an equipment box) through components such as connecting bolts, and it should be noted that the mounting plate 2 and the weighing sensor 1 are both arranged in the equipment box to facilitate hiding;

[0037] The weighing device further comprises a telescopic hanging module, wherein the telescopic hanging module comprises a connecting component, a hanging component and a slide rail component;

[0038] The connecting assembly includes a connecting plate 3, and the slide rail assembly includes a slide rail 4 and a slider 5 that cooperate with each other, wherein the connecting plate 3 is a long strip plate, and the connecting plate 3 is installed on the bottom surface of the weighing sensor 1 by connecting screws, and the slide rail 4 is also connected to the bottom surface of the connecting plate 3 by connecting screws; the slide rail 4 and the slider 5 are preferably T-shaped or dovetail-shaped structures;

[0039] The hanging assembly includes a hanging plate 6, which is a long strip structure. The top surface of one end of the hanging plate 6 is connected to the slider 5 by a connecting screw, so that the hanging plate 6 is slidably connected to the mounting plate 2 through the cooperation of the slide rail 4 and the slider 5;

[0040] The other end surface of the hanging plate 6 is provided with a plurality of plug holes, each of which is plugged with a hanging rod 7, the other end of each hanging rod 7 is in a free state, and a limiting groove 8 is also provided at the free end of the hanging rod 7;

[0041] When in use, the object to be weighed is hung on the suspension rod 7 by a suspension rope, and the position of the suspension rope is limited by the limit groove 8 to prevent the object to be weighed from sliding during the weighing process, which is beneficial to improving the weighing accuracy;

[0042] At the same time, a magnetic door buckle 9 is also provided on the hanging plate 6, and a magnetic baffle 10 is provided at one end of the connecting plate 3 in the direction in which the hanging plate 6 extends. The magnetic door buckle 9 and the magnetic baffle 10 are both provided with permanent magnets, among which rubidium magnets are the best.

[0043] During actual use, the magnetic baffle 10 is located at the end position of the extension of the hanging plate 6. When the hanging plate 6 moves to this position, the magnetic door buckle 9 is bonded to the magnetic baffle 10 by magnetic force, thereby fixing the hanging plate 6 at the end position, ensuring the stability of the hanging plate 6 after extension, avoiding it from accidentally retracting under the action of external force, ensuring the stability of the measurement process, and also avoiding the movement of the hanging plate 6 and the heavy object to affect the weighing accuracy; on the other hand, it can also prevent the heavy object to be weighed from being stuck in the telescopic opening of the hanging plate 6 entering and exiting the chassis, especially preventing the hanging plate 6 from being pinched and injuring the staff when it is accidentally retracted, thereby improving the practical safety of the equipment.

[0044] One end of the suspension plate 6 where the suspension rod 7 is arranged is also connected to a fixing seat 14 through a connecting screw, a rotating shaft is rotatably arranged on the fixing seat 14, a push plate 15 is also rotatably arranged on the rotating shaft, and the push plate 15 is in an L-shaped structure, one end of which is rotatably connected to the rotating shaft, so as to realize the hinged connection between the push plate 15 and the fixing seat 14; at the same time, mounting holes are arranged on the push plate 15 and the suspension plate 6, and permanent magnets are arranged in the two mounting holes, wherein the permanent magnets are preferably rubidium magnets;

[0045] When in use, when one end of the push plate 15 connected to the fixing seat 14 is in a horizontal state, it is in a non-working state. In the non-working state, the two permanent magnets are directly adsorbed against each other to ensure the stability and reliability of the position of the push plate 15;

[0046] When one end of the push plate 15 connected to the fixing seat 14 is in a vertical state, it is in a working state. When the working state needs to be switched, the push plate 15 is manually rotated to a vertical state. By pushing the push plate 15, the suspension rod 7 can be driven to be retracted. The operation is simple and convenient.

[0047] The telescopic weighing device further comprises a driving module and a locking module, wherein the driving module comprises a tension spring 11, connecting screws are arranged on the connecting plate 3 and the hanging plate 6, and pull rings are arranged at both ends of the tension spring 11, and the two pull rings are respectively connected to the two connecting screws;

[0048] It should be noted that the positions of the two connecting screws meet the following requirements, that is, when the hanging plate 6 is in a retracted state, the tension spring 11 is in a stretched state, and when the hanging plate 6 is in an unlocked and extended state, the tension spring 11 is in a natural state;

[0049] Compared with the prior art, the present application can realize the automatic expansion of the telescopic hanging module through a tension spring 11, which simplifies the structure of the whole set of equipment as much as possible, which is conducive to improving the reliability and stability of the whole set of equipment;

[0050] Secondly, the present application uses the tension spring 11 as the main extension power component, eliminating all electric equipment, which not only reduces the cost of the equipment, but also helps to fix the weighing sensor 1 in the chassis, avoids the increase of the weighing radius of the weighing sensor 1, and improves the detection accuracy;

[0051] The locking module includes a push-type door buckle lock head 12 and a push-type door buckle 13 that cooperate with each other. The push-type door buckle lock head 12 is arranged on the hanging plate 6, and the push-type door buckle 13 includes a fixing plate and a door buckle body. The fixing plate is fixed on the connecting plate 3 by screws, and the door buckle body is plugged and installed on the fixing plate; along the sliding direction of the hanging plate 6, the push-type door buckle lock head 12 and the push-type door buckle 13 are arranged opposite to each other.

[0052] The push-type door buckle 13 can be engaged and unlocked by pressing, that is, the locking and unlocking operations can be achieved outside the box by pressing one end of the hanging plate 6 provided with the hanging rod 7. There is no need to set up other devices to achieve locking and unlocking operations, which simplifies the operation of the equipment as much as possible and reduces the difficulty of controlling the equipment.

[0053] Meanwhile, a bracket is provided on the mounting plate 2, and a photoelectric coupler 17 is provided on the bracket. Meanwhile, a baffle 18 adapted to the photoelectric coupler 17 is provided on the hanging plate 6;

[0054] Furthermore, in order to further improve the weighing capacity of the weighing device, a set of weighing sensors 1, telescopic hanging modules and other auxiliary equipment can be set at both ends of the mounting plate 2. At the same time, the mounting plate 2 can also be set to a Y-shaped, cross-shaped or other multi-leg structure as needed, and each leg is provided with a set of weighing equipment.

[0055] When the telescopic weighing device described in the present application is used, it is installed in a chassis or other hidden position through the installation module. In the non-working state, the telescopic hanging module is in a retracted state. At this time, the push-type door buckle lock head and the push-type door buckle are engaged with each other, thereby locking the telescopic hanging module. At this time, the entire weighing device is completely located in the chassis, realizing the concealment of the entire device;

[0056] When weighing is required, the free end of the hanging plate is pressed to unlock the push-type door buckle lock and the push-type door buckle. After unlocking, the telescopic hanging module is in a free state, and the tension spring is also in a pulled state. Under the control of the tension spring, the telescopic hanging module automatically unfolds and extends. When the hanging plate is fully extended, the magnetic door buckle and the magnetic baffle are attached to each other.

[0057] When the weighing is completed and the hanging plate needs to be recovered, the push plate is rotated to put it in a working state, and then the hanging plate is manually compressed and retracted by pushing the push plate, and finally the push-type door buckle lock is pressed and the push-type door buckle is engaged, so that the telescopic hanging module is locked again;

[0058] Compared with the prior art, firstly, the present application can store the entire telescopic hanging module in the box when not in operation, thus avoiding the impact on the appearance of the equipment;

[0059] Secondly, compared with the electric telescopic device, the present application fixes the weighing sensor in the chassis, and only the component for hanging the object to be weighed is extended through the telescopic hanging module. Therefore, it can effectively avoid the increase of the weighing radius of the weighing sensor, thereby ensuring the weighing accuracy.

[0060] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
