Description

Technical Field

[0001] The utility model relates to the field of universal column type weighing sensors, and particularly relates to a universal column type weighing sensor. Background Technique

[0002] A weighing sensor uses a force sensor, based on the principle of a resistance strain type weighing sensor. It can convert the gravity acting on the object to be measured into a measurable output signal in a certain proportion. It is widely used in various electronic weighing devices such as electronic truck scales, vehicle inspection lines, rail scales, and tank scales, and the weighing sensors include universal column type weighing sensors among them.

[0003] After retrieval, a utility model universal weighing sensor with the publication number of CN213336430U includes a chassis. The top of the chassis is provided with four first threaded holes. In this utility model, through the settings of the first threaded holes, threaded posts, and threaded nuts, the position of the chassis can be fixed to prevent the chassis from shifting during weighing, which may cause inaccurate weighing. Under the combined action of the first groove, the second groove, the arc-shaped block, the arc-shaped groove, the ball, and the connecting head, the load tray can weigh in all directions, eliminating the need to wait for the gravity of the weighed item to align with the center line of the elastic body before weighing, thereby improving the weighing efficiency. Through the combined action of the elastic body, the elastic strip, the strain gauge, and the strain strip, the weighing accuracy is jointly improved. Through the settings of the chassis and the hook, when weighing a relatively large object, the device can be weighed in a suspended manner.

[0004] During the use of the existing universal column type weighing sensors, the bearing capacity of the weighing sensor itself has a certain limit. If the weight of the item exceeds the bearing limit of the weighing sensor, it will cause certain damage to the weighing sensor itself. Moreover, the weighing sensor in the above comparison case lacks a buffer protection structure. During the weighing process of the item, when the weight exceeds the limit of the weighing sensor itself, it is easy to cause damage to the weighing sensor body, resulting in a decrease in the accuracy of the weighing sensor and a large error in the measurement result.

[0005] Therefore, it is very necessary to invent a universal column type weighing sensor to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a universal column type weighing sensor to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A universal column type weighing sensor includes a weighing sensor body;

[0008] The housing is installed outside the weighing sensor body and is used to protect the weighing sensor body. Limiting grooves are provided on the lower two side surfaces of the weighing sensor body;

[0009] The installation grooves are all provided around the housing and are used to install the telescopic rods. The telescopic rods are installed inside the installation grooves. A first spring is arranged on the outer side of the upper side of the telescopic rods. The upper end of the telescopic rods is fixedly installed with a buffer block, and the upper end of the buffer block is fixedly installed with an installation frame;

[0010] The flange is movably connected below the weighing sensor body and is used to support the weighing sensor body.

[0011] Preferably, the installation frame is movably connected to the housing through the telescopic rods, and the outer part of the upper end of the weighing sensor body is slidably connected to the inside of the installation frame.

[0012] Preferably, five groups of telescopic rods are provided, and the five groups of telescopic rods are distributed in a circular array on the housing.

[0013] Preferably, internal threads are provided on the inner surface of the installation frame, and a threaded column is movably connected inside the internal threads. The upper end of the threaded column is fixedly installed with a weighing seat.

[0014] Preferably, bolts penetrate through both sides of the flange. A movable rod is movably connected inside both sides of the flange. One end of the movable rod is fixedly installed with a handle, and inner cavities are provided on both sides inside the flange.

[0015] Preferably, a fixed disk is fixedly installed on the outer part of the movable rod, and a second spring is arranged inside the inner cavity.

[0016] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0017] 1. Through the settings of the weighing sensor body, housing, limiting grooves, installation grooves, telescopic rods, first springs, buffer blocks and installation frames, when weighing an item, when the weighing sensor body receives a weight exceeding its own weighing limit, the pressure received by the installation frame is transmitted to multiple groups of telescopic rods below. By using the first springs arranged outside the telescopic rods, the impact force received by the telescopic rods is buffered, so that the pressure received by the installation frame is dispersed in terms of weight, thereby avoiding damage to the weighing sensor body. Such a setting not only plays a role in buffering and protecting the weighing sensor body, but also reduces the damage caused to the weighing sensor body by the overweight of the item;

[0018] 2. Through the settings of the weighing sensor body, limit slots, flanges, bolts, movable rods, handles, inner cavities, fixed disks, and second springs, by using the threaded connection between the mounting bracket and the weighing seat, it is convenient for staff to disassemble and replace the weighing seat according to the size of the item. The weighing sensor body is installed in the flange to avoid the instability of the weighing sensor body during the weighing process. By pulling the handle, the movable rod is telescoped in the flange, and then the weighing sensor body is placed into the flange. At this time, release the handle, and utilize the second spring setting in the inner cavity to rebound the movable rod and insert it into the limit slot below the weighing sensor body to limit and fix the limit slot. This not only strengthens the firmness between the weighing sensor body and the flange but also facilitates disassembly and assembly. Brief Description of the Drawings

[0026] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0027] The present utility model provides a universal column type weighing sensor as Figures 1-4 shown, including a weighing sensor body 1;

[0028] The housing 2 is installed outside the weighing sensor body 1 to protect the weighing sensor body 1. Limiting grooves 3 are provided on both lower side surfaces of the weighing sensor body 1.

[0029] Mounting grooves 4 are provided around the housing 2 for installing the telescopic rods 5. The telescopic rods 5 are installed inside the mounting grooves 4. A first spring 6 is arranged on the outer side of the upper side of the telescopic rod 5. A buffer block 7 is fixedly installed at the upper end of the telescopic rod 5. An installation frame 8 is fixedly installed at the upper end of the buffer block 7.

[0030] The flange 12 is movably connected below the weighing sensor body 1 to support the weighing sensor body 1. When weighing an item, when the weighing sensor body 1 receives a weight exceeding its own weighing limit, the pressure received by the installation frame 8 is transmitted to multiple groups of telescopic rods 5 below. By means of the first spring 6 arranged on the outside of the telescopic rod 5, the impact force received by the telescopic rod 5 is buffered, so that the pressure received by the installation frame 8 is dispersed in weight, thereby preventing the weighing sensor body 1 from being damaged.

[0031] As Figure 1 and Figure 2 shown, the installation frame 8 is movably connected to the housing 2 through the telescopic rod 5. The outer upper end of the weighing sensor body 1 is slidably connected to the inside of the installation frame 8. By means of the cooperation between the telescopic rod 5 and the external telescopic rod 5, the pressure borne by the installation frame 8 is buffered, thereby protecting the weighing sensor body 1 from being damaged.

[0032] As Figure 1 and Figure 2 shown, five groups of telescopic rods 5 are provided. The five groups of telescopic rods 5 are distributed in a circular array on the housing 2. The setting of multiple groups of telescopic rods 5 can disperse the weight pressure borne by the telescopic rods 5, thereby protecting the weighing sensor body 1.

[0033] As Figure 1 and Figure 3 shown, internal threads 9 are provided on the inner surface of the installation frame 8. A threaded column 10 is movably connected inside the internal threads 9. A weighing seat 11 is fixedly installed at the upper end of the threaded column 10. By means of the threaded connection between the installation frame 8 and the weighing seat 11, it is convenient for the staff to disassemble and replace the weighing seat 11 according to the size of the item.

[0034] As Figure 1 and Figure 4 shown, bolts 13 penetrate through both sides of the flange 12. A movable rod 14 is movably connected inside both sides of the flange 12. A handle 15 is fixedly installed at one end of the movable rod 14. Inner cavities 16 are provided on both inner sides of the flange 12. By means of the telescopic movement of the movable rod 14 inside the flange 12, the connection between the weighing sensor body 1 and the flange 12 is strengthened.

[0035] AsFigure 4 As shown, a fixed disk 17 is fixedly installed outside the movable rod 14, and a second spring 18 is arranged inside the inner cavity 16. By arranging the second spring 18 inside the inner cavity 16, the movable rod 14 can be made to rebound, thereby improving the firm limiting property of the movable rod 14 within the flange 12.

[0036] The working principle of this utility model: First, pull the handles 15 on both sides of the flange 12 to make the movable rod 14 expand and contract. At this time, place the weighing sensor body 1 into the flange 12. When the weighing sensor body 1 is placed into the flange 12, then release the handles 15. Through the arrangement of the second spring 18 in the inner cavity 16 opened in the flange 12, the movable rod 14 rebounds and expands and contracts, and the movable rod 14 is inserted into the limiting grooves 3 on both sides below the weighing sensor body 1 for limiting and fixing. Then, the flange 12 is threadedly installed on the equipment or workbench through the bolts 13. After installation, align the threaded column 10 below the weighing seat 11 with the internal thread 9 in the mounting frame 8 and tighten it. At this time, an item can be placed on the weighing seat 11 for weighing. When the item is weighed and the weighing sensor body 1 receives a weight exceeding its own weighing limit, the pressure of the item received by the mounting frame 8 is transmitted to the multiple groups of telescopic rods 5 below. By arranging the first spring 6 outside the telescopic rods 5, the impact force received by the telescopic rods 5 is buffered. And multiple groups of telescopic rods 5 buffer and protect simultaneously, so that the pressure received by the mounting frame 8 is dispersed in terms of weight, thereby avoiding damage to the weighing sensor body 1. Finally, after obtaining the weighed data, remove the item. Due to the rebounding effect of the first spring 6, the telescopic rods 5 push the mounting frame 8 back to the initial height. Just like this, the use process of this universal column type weighing sensor is completed.

[0037] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
