Description

Technical Field

[0001] This utility model belongs to the field of weighing instrument technology, specifically, it relates to a data acquisition electronic platform scale weighing instrument. Background Technology

[0002] An electronic platform scale is a weighing instrument that uses the principle of force deformation of electronic strain gauges to output tiny analog electrical signals, which are transmitted to a weighing display instrument via a signal cable to perform weighing operations and display the weighing results.

[0003] Chinese utility model patent CN209214743U discloses an explosion-proof electronic platform scale, including a weighing pan, a base frame, and a housing. The base frame is fixed on the weighing pan, and the housing is fixed on the base frame. The housing integrates a control panel and a display panel. The key feature is that an explosion-proof outer shell is detachably fitted over the housing. The electronic platform scale transmits data to an external communication device for data interaction.

[0004] Although the platform scale is explosion-proof through its explosion-proof casing, the battery on the scale's instrument requires the mounting plate to be removed before it can be pulled out of the instrument. However, during this process, the battery is prone to falling to the ground, which can damage the battery or even cause it to explode and catch fire. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when replacing the battery on the instrument of a platform scale, the fixing plate must be removed first, and then the battery must be pulled out of the instrument. However, during the pulling process, the battery is prone to falling to the ground, causing damage or even explosion and fire. The present invention adopts the following technical solution.

[0007] A data acquisition electronic platform scale weighing instrument includes an instrument base shell, an instrument top shell detachably connected to the upper end of the instrument base shell, a vertical rod on the weighing platform connected to the bottom of the instrument base shell, a battery fixing plate detachably connected to the back of the instrument base shell, and a clamping assembly installed on the battery fixing plate. The clamping assembly can clamp and remove the battery when the battery fixing plate is removed, and fix the battery inside the battery fixing plate during installation.

[0008] Preferably, the instrument base is provided with limit slots on both sides inside the battery mounting compartment. The battery fixing plate is slidably connected to the two sides near the outer wall. A return spring is provided between the two side plugs and the battery fixing plate. The two sides of the plugs are provided with inclined surfaces. The outer walls of the two side plugs are fixedly connected with a toggle block. Simultaneously, the two side toggle blocks are moved to make them move towards each other, so that the plugs are disengaged from the inside of the limit slots and the battery fixing plate is pulled out.

[0009] Preferably, the clamping assembly includes a sliding rod and a clamping plate. The sliding rod is fixedly connected to the opposite face of the two side plug blocks. The sliding rod is inserted into the inside of the battery clamping compartment. The clamping plate is fixedly connected to the opposite face of the two side sliding rods. The two side plug blocks move towards each other, causing the two side sliding rods and the clamping plate to move towards each other. The two side clamping plates clamp the outer wall of the battery.

[0010] Preferably, the outer walls of the two clamping plates are provided with multiple anti-slip grooves, which increase the friction between the clamping plates and the outer wall of the battery.

[0011] Preferably, the multiple anti-slip grooves are divided into upper and lower parts, and the anti-slip grooves are inclined and the inclination directions of the two parts are opposite.

[0012] Preferably, guide ramps are fixedly connected to the upper and lower ends of the two clamping plates. The two clamping plates extend outward at an angle. The battery is placed inside the battery clamping compartment. Pressing the two toggle blocks causes the two plug blocks and the clamping plates to move towards each other to clamp the battery. The guide ramps can clamp the battery at the center of the battery clamping compartment.

[0013] Preferably, the outer wall of the instrument top housing is provided with a display screen and control buttons, and the back of the instrument bottom housing is provided with an on / off switch.

[0014] Preferably, the battery mounting plate has a battery clamping compartment inside, and the battery is clamped between the battery clamping compartment and the battery mounting compartment. The outer wall of the top cover of the instrument is provided with a display screen and control buttons, and the back of the bottom cover of the instrument is provided with an on / off switch.

[0015] Preferably, the back of the instrument base is provided with multiple insertion posts, and the inside of the battery fixing plate is provided with multiple insertion cylinders, into which the insertion posts are inserted.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. When replacing the battery, continuously pressing the connector block can keep the clamping plate holding the battery in place. When the battery fixing plate is removed, the battery is always fixed in the clamping compartment, avoiding the problem of the battery easily falling out of the compartment and falling to the ground and causing damage in traditional disassembly methods. This protects the battery and reduces the replacement cost caused by battery damage.

[0018] 2. The anti-slip grooves tilted in the opposite direction on the clamping plate can create bidirectional resistance to the battery during the process of removing the battery fixing plate from the bottom of the instrument, preventing it from sliding vertically due to gravity, thus further improving the safety of the disassembly operation. It is especially suitable for scenarios where the instrument is installed at a high position or where the operator's hands are inconvenient.

[0019] 3. The sliding rod, clamping plate, and plug-in block inside the battery fixing plate are linked. When the plug-in block is pressed, the clamping plates on both sides can move synchronously in opposite directions to tightly clamp the battery. In addition, the anti-slip groove on the outer wall of the clamping plate is divided into upper and lower parts with opposite inclination directions. This not only increases the friction to prevent the battery from loosening during clamping, but also prevents the battery from sliding vertically when the battery fixing plate is removed. This solves the problem of batteries being easy to loosen and fall off in traditional structures, ensuring the stability of the battery during disassembly, assembly, and use.

[0020] 4. The plug-in pins on the back of the instrument base cooperate with the plug-in sleeves of the battery mounting plate, allowing for quick positioning of the battery mounting plate during installation and avoiding installation difficulties caused by misalignment. At the same time, the guide plates at the upper and lower ends of the clamping plate extend outward, automatically guiding the battery to the center of the battery clamping compartment when it is inserted. There is no need to manually adjust the battery position; the battery installation can be completed simply by fixing the battery mounting plate, further reducing the installation difficulty.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0033] like Figure 1 as well as Figure 2 The diagram shows a preferred embodiment of the weighing instrument for a data acquisition electronic platform scale. The weighing instrument in this embodiment includes a base shell 100, a top shell 101 detachably connected to the upper end of the base shell 100, and a vertical rod on the weighing platform connected to the bottom of the base shell 100. A display screen 102 and control buttons 103 are provided on the outer wall of the top shell 101. A power switch 104 is provided on the back of the base shell 100. A battery mounting compartment 105 is located on the inner side of the base shell 100 near the back, and a battery is inserted into the battery mounting compartment 105 to power the instrument. A battery fixing plate 200 is detachably connected to the back of the base shell 100. In this embodiment, when replacing the battery, the battery fixing plate 200 is first removed, then the battery is pulled out from the battery mounting compartment 105 and a new battery is inserted. The battery replacement is completed by resetting the battery fixing plate 200.

[0034] like Figure 1As shown, the instrument has a built-in 4G transmission module, automatic positioning module, automatic gravity speed compensation module, photo acquisition module, and anti-tamper detection module. The photo acquisition module can take pictures of the weighed object, and the 4G module can automatically upload weighing data and photo data. Electronic scales are subject to gravity deviation due to the Earth's gravity, so weight compensation is required for different regions. The instrument has a built-in national regional compensation algorithm. When powered on, the automatic positioning module searches for the location region, and the automatic gravity speed compensation module automatically adjusts the compensation weight to achieve the purpose of automatic data acquisition.

[0035] like Figure 2 as well as Figure 3 As shown, this is a schematic diagram of the quick-release assembly structure in this embodiment. The instrument base 100 has limit slots 106 on both sides inside the battery mounting compartment 105. The battery fixing plate 200 has insertion blocks 201 slidably connected to its two sides near the outer wall. A return spring 202 is provided between the two insertion blocks 201 and the battery fixing plate 200. Inclined surfaces are provided on both sides of the insertion blocks 201. A toggle block 204 is fixedly connected to the outer wall of the two insertion blocks 201. In this embodiment, when removing the battery, the toggle block 204 causes the two insertion blocks 201 to move simultaneously towards each other and compress. The positioning spring 202 allows the plug block 201 to disengage from the inside of the limiting slot 106, thereby enabling the battery fixing plate 200 to be removed and the internal battery to be taken out for replacement. When installing the battery fixing plate 200, the inclined surface on the plug block 201 causes the plug blocks 201 on both sides to retract inward when the battery fixing plate 200 is facing the back of the instrument base 100. When the plug block 201 is facing the limiting slot 106, the return force of the return spring 202 causes the plug block 201 to insert into the inside of the limiting slot 106, thereby achieving the purpose of quick installation and removal.

[0036] like Figure 2 as well as Figure 3 As shown, the back of the instrument base 100 is provided with multiple plug-in pins 107, and the inside of the battery fixing plate 200 is provided with multiple plug-in cylinders 205. The plug-in pins 107 are inserted into the inside of the plug-in cylinders 205. In this embodiment, by inserting the plug-in pins 107 into the plug-in cylinders 205, the battery fixing plate 200 can be positioned when it is installed, making it easier to install.

[0037] like Figure 4As shown, this is a schematic diagram of the clamping assembly structure in this embodiment. The battery fixing plate 200 has a battery clamping compartment 108 inside, and the battery is clamped between the battery clamping compartment 108 and the battery mounting compartment 105. The opposite surfaces of the two side plug-in blocks 201 are fixedly connected to sliding rods 207, which are inserted into the inside of the battery clamping compartment 108. The opposite surfaces of the two side sliding rods 207 are fixedly connected to clamping plates 208. In this embodiment, when the battery needs to be replaced, pressing the two side plug-in blocks 201 causes the two side sliding rods 207 and clamping plates 208 to move towards each other simultaneously, thereby enabling the two side clamping plates 208 to move inward simultaneously to clamp the battery. This allows the battery to be pulled out from inside the instrument bottom case 100 when the battery fixing plate 200 is removed, and continuous pressing of the plug-in blocks 201 can prevent the battery from falling out when the battery fixing plate 200 is removed.

[0038] like Figure 6 As shown, this is the embodiment of the present invention. Figure 5 The enlarged structural diagram at point A shows that the outer walls of the clamping plates 208 on both sides are provided with multiple anti-slip grooves 206. The multiple anti-slip grooves 206 are divided into upper and lower parts, and the anti-slip grooves 206 are inclined with opposite inclination directions. In this embodiment, the anti-slip grooves 206 can increase the friction between the clamping plate 208 and the outer wall of the battery, making the battery more secure. By setting the two parts with opposite inclination directions, the battery can be prevented from sliding vertically downwards and falling to the ground when the battery fixing plate 200 is removed.

[0039] like Figure 5 As shown, this is a schematic diagram of the positioning component structure in this embodiment. Guide inclined plates 209 are fixedly connected to the upper and lower ends of the two clamping plates 208. The two clamping plates 208 extend outward at an angle. In this embodiment, the battery is placed inside the battery clamping compartment 108 by setting the guide inclined plates 209. By pressing the two toggle blocks 204, the two plug-in blocks 201 and the clamping plates 208 move towards each other to clamp the battery. The guide inclined plates 209 can clamp the battery at the center of the battery clamping compartment 108, so that the battery can be automatically positioned at the center of the battery clamping compartment 108 when installing the battery. The battery installation can be completed by simply installing and fixing the battery fixing plate 200, making the battery installation more convenient.

[0040] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
