Description

Technical Field

[0001] The utility model relates to the technical field of object weighing, in particular to a column type weighing device. Background Art

[0002] Weighing devices are widely used in industrial, agricultural, commercial, scientific research, medical and health departments, etc. Weighing devices are customarily called scales. A weighing device measures the mass of an object by using the principle of deformation balance of force (Hooke's law). Deformation balance (Hooke's law) measures the mass of the object to be measured according to the elastic body deformation amount caused by the self-weight of the object to be measured, and the deformation amount changes with the change of gravitational acceleration; lever balance measures the mass of the object to be measured according to the balance of the calibrated weight and the weight of the object to be measured on the lever. Lever balance is independent of the change of gravitational acceleration, but when the gravitational acceleration is zero, weighing will fail.

[0003] After retrieval, a utility model patent with the Chinese patent publication number CN219641072U discloses a weighing device, including an electronic scale. A placement plate is arranged on the surface of the scale pan of the electronic scale. An elastic telescopic member is arranged on the surface of the placement plate. A scraping plate is connected to the telescopic end of the elastic telescopic member. The bottom surface of the scraping plate abuts against the surface of the placement plate. The beneficial effect is that: the elastic telescopic member is used to push the scraping plate to move on the surface of the placement plate, and the raw materials falling on the surface of the placement plate are pushed away from the placement plate by the scraping plate, realizing automatic cleaning, ensuring the subsequent weighing accuracy, and helping to improve production efficiency.

[0004] After retrieval, the above patent has dealt with the cleaning of the device, but the device fails to deal with the internal convenient maintenance. When the weighing device fails, it takes a lot of time and energy to remove the housing and perform maintenance on the inside of the weighing device, resulting in cumbersome and complex operations. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a column type weighing device, which realizes the effect of convenient later maintenance and repair through this device, so as to solve the problem of inconvenient later maintenance and repair in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A column type weighing device includes a base. A weighing sensor is arranged at the upper end of the base. A housing is arranged at the upper end of the base. The housing is arranged outside the weighing sensor and is used for protecting the weighing sensor; a weighing plate is arranged at the upper end of the housing. A plurality of sliding rods are arranged in a circular array at the lower end of the weighing plate. A plurality of rod bodies are arranged in a circular array at the upper end of the base. The sliding rods are slidably connected inside the rod bodies. A buffer assembly is arranged inside the rod bodies. The lower end of the sliding rod is attached to the upper end of the buffer assembly. The buffer assembly is used for buffering and protecting the device.

[0008] Preferably, a plurality of rotating rods are arranged in an annular array inside the load cell, and the lower end of the rotating rod is rotationally connected to the upper end of the base by a thread.

[0009] Preferably, a fixing block is fixedly connected to the lower end of the weighing plate, and the lower end of the fixing block is attached to the upper end of the load cell.

[0010] Preferably, the buffer assembly includes a movable plate, the movable plate is slidably connected to the rod body, a first spring is fixedly connected between the lower end of the movable plate and the inner bottom of the rod body, and the upper end of the movable plate is attached to the lower end of the sliding rod.

[0011] Preferably, a plurality of chutes are arranged in an annular array inside the base, a plurality of through grooves are arranged in an annular array at the upper end of the base, the lower end of the through groove communicates with the upper end of the chute, a groove is arranged inside the chute, a plurality of plates are arranged in an annular array on the side wall of the housing, and the plates are slidably connected to the grooves.

[0012] Preferably, a notch is arranged at the lower end of the chute, a top block is slidably connected inside the notch, a second spring is fixedly connected between the lower end of the top block and the inner bottom of the notch, and the upper end of the top block is attached to the lower end of the plate.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] 1. The operator manually rotates the rotating rod to make the rotating rod threadedly connected to the base, fixedly installs the load cell on the upper end of the base, then slides the plate into the chute through the through groove, and then manually rotates the housing to make the plate slide inside the chute. During the process of the plate sliding inside the chute, the inclined end of the plate contacts the inclined end of the top block, so that the top block slides into the notch. When the plate slides below the groove, the top block is elastically pushed by the second spring to push the plate upward into the groove, thereby quickly clamping and connecting the housing and the base, which is convenient for later maintenance and repair of the inside of the weighing device.

[0015] 2. When weighing an object, the operator places the object on the upper end of the weighing plate. Through the cooperation between the first spring and the movable plate, the weighing plate drives the object and the fixing block to slowly move downward, so that the lower end of the fixing block contacts the upper end of the load cell, and then the object is weighed by the load cell, thereby buffering and protecting the weighing device, and avoiding damage to the weighing device caused by the rapid downward movement of the fixing block driven by the weighing plate due to the weight of the object, which may cause a collision between the weighing plate and the fixing block and the weighing device.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a column type weighing device includes a base 1. A weighing sensor 2 is arranged at the upper end of the base 1. A housing 4 is arranged at the upper end of the base 1. The housing 4 is arranged outside the weighing sensor 2 and is used for protecting the weighing sensor 2; a weighing plate 5 is arranged at the upper end of the housing 4. A plurality of sliding rods 7 are annularly and arrayedly distributed at the lower end of the weighing plate 5. A plurality of rod bodies 8 are annularly and arrayedly distributed at the upper end of the base 1. The sliding rods 7 are slidably connected to the inside of the rod bodies 8. A buffer assembly is arranged inside the rod bodies 8. The lower end of the sliding rod 7 is in contact with the upper end of the buffer assembly. The buffer assembly is used for buffering and protecting the device. The operator installs the weighing sensor 2 at the upper end of the base 1, and then installs the housing 4 at the upper end of the base 1. The housing 4 protects the weighing sensor 2. After installing the weighing sensor 2 and the housing 4, the weighing plate 5 is installed at the upper end of the housing 4, so that the sliding rods 7 slide into the inside of the rod bodies 8. When an object needs to be weighed, the operator places the object on the upper end of the weighing plate 5. Through the buffer assembly, the weighing plate 5 drives the object to move downward slowly, and then the weighing sensor 2 weighs the object.

[0023] A plurality of rotating rods 3 are annularly and arrayedly distributed inside the weighing sensor 2. The lower end of the rotating rod 3 is in threaded rotational connection with the upper end of the base 1. By manually rotating the rotating rod 3, the rotating rod 3 is in threaded connection with the base 1, so as to fixedly install the weighing sensor 2 at the upper end of the base 1.

[0024] A fixed block 6 is fixedly connected to the lower end of the weighing plate 5. The lower end of the fixed block 6 is in contact with the upper end of the weighing sensor 2. When the weighing plate 5 moves downward, the fixed block 6 is driven to move, so that the lower end of the fixed block 6 contacts the upper end of the weighing sensor 2.

[0025] The buffer assembly includes a movable plate 9. The movable plate 9 is slidably connected to the rod body 8. A first spring 10 is fixedly connected between the lower end of the movable plate 9 and the inner bottom of the rod body 8. The upper end of the movable plate 9 is in contact with the lower end of the sliding rod 7. When the weighing plate 5 does not weigh an object, the first spring 10 pushes the movable plate 9 upward, and at the same time the movable plate 9 pushes the sliding rod 7, so that the fixed block 6 moves away from the weighing sensor 2.

[0026] A plurality of sliding grooves 11 are arranged in an annular array inside the base 1. A plurality of through grooves 12 are arranged in an annular array at the upper end of the base 1. The lower end of the through groove 12 communicates with the upper end of the sliding groove 11. A groove 13 is arranged inside the sliding groove 11. A plurality of plates 17 are arranged in an annular array on the side wall of the housing 4. The plates 17 are slidably connected to the grooves 13. The plates 17 slide into the sliding grooves 11 through the through grooves 12, and then the housing 4 is manually rotated, so that the plates 17 slide inside the sliding grooves 11 to below the grooves 13, and the ends of the plates 17 are inclined.

[0027] A notch 14 is arranged at the lower end of the sliding groove 11. A top block 15 is slidably connected inside the notch 14. A second spring 16 is fixedly connected between the lower end of the top block 15 and the inner bottom of the notch 14. The upper end of the top block 15 is in contact with the lower end of the plate 17. The end of the top block 15 is inclined. During the process of the plate 17 sliding inside the sliding groove 11, the inclined end of the plate 17 contacts the inclined end of the top block 15, so that the top block 15 slides into the notch 14. When the plate 17 slides to below the groove 13, the elastic force of the second spring 16 pushes the top block 15, and the plate 17 is pushed upward into the groove 13, thereby clamping and connecting the housing 4 and the base 1.

[0028] In the present utility model, the operator manually rotates the rotating rod 3, so that the rotating rod 3 is threadedly connected to the base 1, and the weighing sensor 2 is fixedly installed at the upper end of the base 1. Then the plate 17 is slid into the sliding groove 11 through the through groove 12, and then the housing 4 is manually rotated, so that the plate 17 slides inside the sliding groove 11. During the process of the plate 17 sliding inside the sliding groove 11, the inclined end of the plate 17 contacts the inclined end of the top block 15, so that the top block 15 slides into the notch 14. When the plate 17 slides to below the groove 13, the elastic force of the second spring 16 pushes the top block 15, and the plate 17 is pushed upward into the groove 13, thereby quickly clamping and connecting the housing 4 and the base 1.

[0029] After the weighing sensor 2 and the housing 4 are installed, the operator slides the sliding rod 7 into the rod body 8, and through the cooperation between the first spring 10 and the movable plate 9, the weighing plate 5 drives the fixed block 6 to move away from the weighing sensor 2.

[0030] When it is necessary to weigh an object, the operator places the object on the upper end of the weighing plate 5. Through the cooperation between the first spring 10 and the movable plate 9, the weighing plate 5 drives the object and the fixed block 6 to move downward slowly, so that the lower end of the fixed block 6 contacts the upper end of the weighing sensor 2, and then the weighing sensor 2 weighs the object.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
