Description

Technical Field

[0001] The utility model relates to the technical field of electronic hanging scales, in particular to a hanging type electronic hanging scale. Background Art

[0002] An electronic crane scale is a measuring instrument used to weigh suspended objects online. It typically consists of a load cell, a mechanical load-bearing mechanism, and a weight display. Most electronic crane scales have only a single hook at the bottom. When weighing steel pipes or a series of cylindrical objects, the pipes often need to be bundled and then suspended from the hook, which is time-consuming and labor-intensive, making it inconvenient to directly weigh the pipes. This limits the applicability of electronic crane scales and their limitations.

[0003] The Chinese utility model patent publication number CN221612228U discloses an electronic hanging scale with double hooks, comprising a main unit, a hanging ring provided on the top of the main unit, a pull rod provided on the bottom of the main unit, a horizontal box provided on the bottom of the pull rod, a bidirectional screw rotatably mounted inside the horizontal box, two sliders slidably mounted inside the horizontal box, a connecting ring provided on the top of the hook, and the connecting ring provided in a notch via a connector. The above arrangement facilitates the weighing of steel pipes. The arrangement of the handle, bidirectional screw, and slider facilitates the horizontal placement of the steel pipe, thereby ensuring the accuracy of weighing. The arrangement of the connector allows the use of a single hook for weighing, avoiding the problem of double hooks affecting the hanging process of the weighed object, thereby expanding the scope of application of the hanging scale.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: the above-mentioned device limits the hooks through plug-in connectors. When there is no need to weigh the steel pipe, the staff needs to remove one of the hooks. However, at this time, the slider still remains on the bidirectional screw. In order to improve the accuracy of the detection, the staff needs to move the remaining hooks to the middle of the bidirectional screw. At this time, the extra slider also moves toward the middle of the bidirectional screw, which is easy to interfere with the staff's operation and the user experience is poor. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a hanging electronic crane scale.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a hanging electronic hanging scale, including a main body, a hanging ring arranged on the main body, a pull rod interconnected with the main body and a horizontal box connected with the pull rod, the bottom surface of the horizontal box is open, a placement rod is fixed on the inner wall of the horizontal box, a plurality of fixing rods are arranged on the placement rod, a hook is connected to the bottom surface of the fixing rod, a connecting rod is fixed on the upper surface of the fixing rod, a placement groove matching the placement rod is provided on the side wall of the fixing rod, a connecting groove interconnected with the placement groove is provided on the upper surface of the connecting rod, a limiting groove is provided on the inner wall of the connecting groove, and a limiting component for limiting the fixing rod is provided on the connecting rod.

[0007] By adopting this technical solution, when a worker needs to weigh a steel pipe, they simply connect the steel pipe to multiple hooks simultaneously, and the main unit can measure the weight of the steel pipe. Later, when the worker needs to weigh additional objects, they simply close the limit assembly and pull the fixing rod to separate the extra hooks from the placement rod. Furthermore, the worker slides the hook to the middle of the placement rod. Afterwards, the worker simply hangs the object on the hook, and the main unit weighs the object, reducing the operator's operational difficulty.

[0008] Furthermore, the limit assembly includes a limit rod slidably set in the limit groove, a limit spring with one end fixed on the side wall of the limit rod, and a driving device set on the connecting rod for driving the limit rod, and the other end of the limit spring is fixed on the inner wall of the limit groove.

[0009] Furthermore, a driving groove is provided on the side wall of the horizontal box, and the driving device includes an elastic rope with one end fixed to the side wall of the limiting rod close to the limiting spring and a fixing ring fixed to the end of the elastic rope.

[0010] By adopting the above technical solution, when the worker needs to install the hook, the worker only needs to pull the fixing ring, and the elastic rope will follow the fixing ring to move, and then the limit rod will be fully moved into the limit groove under the action of the elastic rope. Furthermore, the worker needs to connect the installation rod with the installation groove and loosen the fixing ring. The limit rod will then connect with the limit hole under the action of the limit spring, so that the limit rod blocks the installation rod and thus maintains the stability of the hook.

[0011] Furthermore, a movable groove is provided on the bottom surface of the limiting rod, a movable block is slidably arranged in the movable groove, a threaded rod is rotatably provided on the upper surface of the movable block, the upper end of the threaded rod extends to the outside of the limiting rod and is slidably connected, and a sliding groove for accommodating the threaded rod is provided on the upper surface of the connecting rod.

[0012] Furthermore, a rubber sheet is fixed to the bottom surface of the moving block.

[0013] By adopting the above technical solution, when the limit rod blocks the placement rod, the staff only needs to rotate the threaded rod to move the threaded rod downward, so that the rubber sheet presses against the placement rod, thereby limiting the position of the hook, thereby reducing the probability of the hook position changing at this time.

[0014] Furthermore, a limiting hole matching the limiting rod is formed on the inner wall of the communicating groove away from the limiting groove.

[0015] Furthermore, the bottom surface of the rubber sheet is arc-shaped.

[0016] By adopting the above technical solution, the contact area between the rubber sheet and the placement rod is increased, thereby further improving the stability of the hook and reducing the probability of the hook changing its position when subjected to external force.

[0017] Furthermore, a driving block is fixed on the upper surface of the threaded rod to reduce the difficulty of workers in rotating the threaded rod.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. In this application, when the staff needs to weigh a steel pipe, the staff needs to connect the steel pipe to multiple hooks at the same time, and then the weight of the steel pipe can be measured through the main body. Then, when the staff needs to weigh other objects, the staff only needs to close the limit assembly and pull the fixing rod to separate the extra hooks from the placement rod. Furthermore, the staff needs to slide the hook and move it to the middle of the placement rod. Then, the staff only needs to hang the object on the hook to weigh the object through the main body, thereby reducing the difficulty of operation for the staff;

[0020] 2. In this application, when the staff needs to install the hook, they only need to pull the fixing ring to make the elastic rope move with the fixing ring, and then the limit rod is completely moved into the limit groove under the action of the elastic rope. Furthermore, the staff needs to connect the installation rod with the installation groove and loosen the fixing ring. The limit rod can then connect with the limit hole under the action of the limit spring, so that the limit rod blocks the installation rod, thereby keeping the hook stable.

[0021] 3. In this application, when the limit rod blocks the placement rod, the staff only needs to rotate the threaded rod to move the threaded rod downward, so that the rubber sheet presses against the placement rod, thereby limiting the position of the hook, thereby reducing the probability of the hook position changing at this time.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] like Figure 1-4 As shown, the embodiment of the present application discloses a hanging electronic hanging scale, including a main body 1, a lifting ring 11, a pull rod 2, a transverse box 21, a placement rod 3, a fixed rod 31, a hook 4, a connecting rod 41, a limit assembly 6, a moving block 81, a threaded rod 82 and a rubber sheet 85. The lifting ring 11 is arranged on the main body, the pull rod 2 is connected to the main body, the transverse box 21 is connected to the pull rod 2, and the bottom surface of the transverse box 21 is open. The placement rod 3 is a round rod-shaped structure, and the placement rod 3 is fixed on the inner wall of the transverse box 21. The fixed rod 31 is a rod-shaped structure, and a plurality of fixed rods 31 are provided and distributed in sequence on the placement rod 3. A plurality of hooks 4 are provided and correspond one to one with the fixed rod 31, and the hooks 4 are connected to the bottom surface of the fixed rod 31. The connecting rod 41 is a rectangular rod-shaped structure, and the connecting rod 41 is fixed to the upper surface of the fixed rod 31, and a placement groove 5 that matches the placement rod 3 is opened on the side wall of the fixed rod 31.

[0029] The upper surface of the connecting rod 41 defines a connecting groove 51 that communicates with the mounting groove 5. A limiting groove 52 is defined within the inner wall of the connecting groove 51. A limiting assembly 6 is provided on the connecting rod 41 to limit the position of the fixing rod 31. The limiting assembly 6 comprises a limiting rod 61, a limiting spring 62, and a driving device 7. The limiting rod 61 is a rectangular rod-shaped structure that slides within the limiting groove 52. One end of the limiting spring 62 is fixed to the side wall of the limiting rod 61, and the other end is fixed to the inner wall of the limiting groove 52.

[0030] A drive slot 63 is defined in the sidewall of the horizontal box 21. A drive mechanism 7 is mounted on the connecting rod 41 and is used to drive the limiting rod 61. The drive mechanism 7 comprises an elastic cord 71 and a fixing ring 72. One end of the elastic cord 71 is fixed to the sidewall of the limiting rod 61 near the limiting spring 62. The fixing ring 72 is an annular structure, and the fixing ring 72 and the end of the elastic cord 71 are fixed to each other.

[0031] When the worker needs to install the hook 4, the worker only needs to pull the fixing ring 72 to make the elastic rope 71 move along with the fixing ring 72, and then the limiting rod 61 is completely moved into the limiting groove 52 under the action of the elastic rope 71. Furthermore, the worker needs to connect the placement rod 3 with the placement groove 5 and loosen the fixing ring 72. The limiting rod 61 can then be connected to the limiting hole 84 under the action of the limiting spring 62, so that the limiting rod 61 blocks the placement rod 3, and thus the hook 4 remains stable.

[0032] The bottom surface of the limiting rod 61 defines a movement groove 8. A block-shaped moving block 81 is slidably mounted within the movement groove 8. A threaded rod 82 is rotatably mounted on the top surface of the moving block 81. The upper end of the threaded rod 82 extends beyond the limiting rod 61 and is slidably connected thereto. A sliding groove 83 is defined on the top surface of the connecting rod 41 for accommodating the threaded rod 82. A sheet-shaped rubber sheet 85 is fixed to the bottom surface of the moving block 81.

[0033] When the limiting rod 61 blocks the placement rod 3, the staff only needs to rotate the threaded rod 82 to move the threaded rod 82 downward, so that the rubber sheet 85 presses against the placement rod 3, thereby limiting the position of the hook 4, thereby reducing the probability of the position of the hook 4 changing at this time.

[0034] In order to improve the blocking effect of the limiting rod 61 , a limiting hole 84 matching with the limiting rod 61 is opened on the inner wall of the communicating groove 51 away from the limiting groove 52 .

[0035] In order to reduce the probability of the hook 4 changing position when subjected to external force, the bottom surface of the rubber sheet 85 is arc-shaped. This arrangement increases the contact area between the rubber sheet 85 and the placement rod 3, thereby further improving the stability of the hook 4 and reducing the probability of the hook 4 changing position when subjected to external force.

[0036] In order to reduce the difficulty for the staff to rotate the threaded rod 82, a driving block 9 is fixed to the upper surface of the threaded rod 82.

[0037] The operating principle of a hanging electronic crane scale in this embodiment is as follows: when a worker needs to weigh a steel pipe, they simply connect the steel pipe to multiple hooks 4 simultaneously, and then measure the weight of the steel pipe through the main body. Later, when the worker needs to weigh additional objects, the worker simply closes the limit assembly 6 and pulls the fixing rod 31 to separate the additional hooks 4 from the mounting rod 3. Furthermore, the worker slides the hook 4 and moves it to the middle of the mounting rod 3. After that, the worker simply hangs the object on the hook 4, and the main body 1 can weigh the object, thus reducing the operator's operating difficulty.
