Description

Technical Field

[0001] This utility model belongs to the technical field of weighing and measuring equipment, specifically a modular structure for electronic floor scales with quickly replaceable sensors. Background Technology

[0002] Electronic floor scales, also known as electronic weighbridges or electronic platform scales, are low-to-medium range static weighing devices based on electronic sensing technology and digital signal processing technology. They are mainly used in industrial, commercial, and logistics scenarios to measure the weight of goods. They are characterized by accurate measurement, convenient operation, and high functional integration. They are one of the basic devices in modern weighing management systems. The electronic floor scale sensor is the core sensing component of the electronic floor scale, which directly determines the weighing accuracy, stability, and reliability of the electronic floor scale.

[0003] Currently, most sensors in electronic weighbridges are installed using integrated methods such as bolt fixing and welding. When it is necessary to replace the sensor, the process is cumbersome, time-consuming, and the disassembly process is complicated. It requires the use of various tools such as wrenches and screwdrivers to remove the fixing bolts one by one. Some welded structures even require cutting operations, which is time-consuming. Therefore, to address the above problems, a modular structure for electronic weighbridges that allows for quick sensor replacement is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a modular structure for electronic floor scales with quick sensor replacement.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the modular structure of the electronic floor scale with quick sensor replacement described in this utility model includes a weighing platform, a U-shaped frame and a sensor; a display is installed on the top of the weighing platform, a fixing ring is fixed to the bottom of the sensor, and a quick-release component is provided on the surface of the U-shaped frame.

[0006] The quick-release assembly includes a support ring mounted on the surface of a U-shaped frame. The support ring has slots on both sides, and clamping blocks are movably connected in the slots. Two bidirectional lead screws are rotatably connected inside the two clamping blocks. A rotary knob is provided on one side of the bidirectional lead screws. The opposing surfaces of the two clamping blocks have grooves that match the fixing ring.

[0007] Preferably, one side of the weighing platform has no annular groove, and the top of the sensor is provided with a limiting ball that matches the annular groove.

[0008] Preferably, the surface of the limiting ball is provided with a first magnetic ring, and one end of the fixing ring is provided with a second magnetic ring.

[0009] Preferably, the first magnetic ring and the second magnetic ring are positioned opposite each other, and the first magnetic ring and the second magnetic ring are attracted to each other by attraction.

[0010] Preferably, the weighing platform has grooves at both ends at the bottom, a slide rail is installed in the groove, a slider is slidably connected to the surface of the limiting ball, and the slider is fixedly connected to the U-shaped frame.

[0011] Preferably, the weighing platform is fixedly connected to the four corners of its bottom edge with support columns, and the surface of the weighing platform is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a modular structure for electronic floor scales with quick sensor replacement. By rotating the rotary knob, the rotary knob drives the bidirectional lead screw to rotate. Since the threads at both ends of the bidirectional screw are in opposite directions, the clamping blocks at both ends of the surface will move in opposite directions or relative to each other, so that the grooves on the opposite surfaces of the clamping blocks disengage from the fixing ring at the bottom of the sensor, thereby releasing the fixing restriction at the bottom of the sensor and completing the sensor disassembly. The entire replacement process does not require complicated tools, greatly shortening maintenance time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 This utility model provides a modular structure for an electronic floor scale with quick sensor replacement, including a weighing platform 1, a U-shaped frame 2, and a sensor 3. When the weighing platform 1 bears weight, it will transfer the weight to the sensor 3. A display 101 is installed on the top of the weighing platform 1. The sensor 3 receives the pressure and transmits it to the display 101 through the built-in circuit to display the weight. A fixing ring 301 is fixed to the bottom of the sensor 3. A quick-release assembly is provided on the surface of the U-shaped frame 2.

[0026] The quick-release assembly includes a support ring 201 mounted on the surface of the U-shaped frame 2. The support ring 201 has slots on both sides, and clamping blocks 204 are movably connected within these slots. A bidirectional lead screw 202 is rotatably connected inside the two clamping blocks 204. When the bidirectional lead screw 202 rotates, the two clamping blocks 204, which are threaded to it, move relative to each other or in opposite directions. A rotary knob 205 is located on one side of the bidirectional lead screw 202, allowing for selective mounting of the lead screw 202 by rotating the knob. The opposing surfaces of the two clamping blocks 204 have recesses... The convex and concave grooves match the retaining ring 301. The irregular design makes the clamping block 204 clamp more firmly. By rotating the rotary knob 205, the rotary knob 205 drives the bidirectional lead screw 202 to rotate. Since the threads at both ends of the bidirectional screw are opposite, the clamping blocks 204 at both ends will move in opposite directions, so that the convex and concave grooves on the opposite side of the clamping block 204 disengage from the retaining ring 301 at the bottom of the sensor 3, thereby releasing the fixing restriction at the bottom of the sensor 3 and completing the disassembly of the sensor 3. The entire replacement process does not require complicated tools, which greatly shortens the maintenance time.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, an annular groove 302 is provided on one side of the weighing platform 1, and a limiting ball 4 is provided on the top of the sensor 3. The limiting ball 4 matches the annular groove 302 and can slide along the annular groove 302 to limit the sensor 3. A first magnetic ring is provided on the surface of the limiting ball 4, and a second magnetic ring is provided at one end of the fixing ring 301. The first magnetic ring and the second magnetic ring are positioned opposite each other and are attracted by attraction. The first magnetic ring on the surface of the limiting ball 4 and the second magnetic ring at one end of the fixing ring 301 are attracted by attraction, which can be used as an additional auxiliary positioning tool to prevent the sensor 3 from sliding. It is worth noting that the magnetic design is only used for auxiliary positioning and the separation can be easily overcome by magnetic force without additional tools.

[0028] Furthermore, such as Figure 2 As shown, the weighing platform 1 has grooves at both ends of its bottom, and a slide rail 401 is installed in the groove. A slider is slidably connected to the surface of the limiting ball 4. The slider is fixedly connected to the U-shaped frame 2. When the sensor 3 is installed, the position of the sensor 3 is adjusted by sliding the slider along the slide rail 401 to ensure that the limiting ball 4 and the fixing ring 301 are accurately aligned. Support columns 102 are fixedly connected to the four corners of the bottom of the weighing platform 1. The support columns 102 at the four corners of the bottom can stably support the entire weighing platform 1 and prevent the platform from tilting and affecting the pressure sensing accuracy of the sensor 3. The surface of the weighing platform 1 is provided with anti-slip texture. The anti-slip texture on the surface of the weighing platform 1 can increase the friction between the object and the platform and avoid weight deviation caused by the object sliding during the weighing process.

[0029] Working principle: When the object to be weighed is placed on the surface of the weighing platform 1, the weighing platform 1 bears the weight of the object and transmits the pressure to the sensor 3. After receiving the pressure signal, the sensor 3 transmits it to the display 101 on the top of the weighing platform 1. The display 101 processes the electrical signal and displays the weight value of the object, completing the basic weighing process. At the same time, the anti-slip texture on the surface of the weighing platform 1 can increase the friction between the object and the platform, avoiding weight deviation caused by the object sliding during the weighing process. The support columns 102 at the four corners of the bottom can stably support the entire weighing platform 1, preventing the platform from tilting and affecting the pressure sensing accuracy of the sensor 3. When the sensor 3 needs to be replaced, pull the U-shaped frame 2 out along the slide rail 401, and rotate the rotary knob 205 on one side of the bidirectional lead screw 202 in the quick release assembly. Rotating the rotary knob 205 drives the bidirectional lead screw 202 to rotate. Since the bidirectional lead screw 202 is rotatably connected to the two clamping blocks 204, and the threads at both ends of the lead screw are in opposite directions, during rotation, the two clamping blocks 204 will be driven to move in opposite directions along the slots of the support ring 201. This causes the grooves on the opposite sides of the clamping blocks 204 to disengage from the fixing ring 301 at the bottom of the sensor 3, thus releasing the fixing restriction at the bottom of the sensor 3. After the bottom of the sensor 3 is released, although the first magnetic ring on the surface of the limiting ball 4 and the second magnetic ring at one end of the fixing ring 301 are attracted by attraction, the magnetic force is only used for auxiliary positioning. The magnetic force can be easily overcome and the separation can be completed without additional tools. At this point, the old sensor 3 is completely disassembled. By rotating the rotary knob 205, the rotary knob 205 drives the bidirectional lead screw 202 to rotate. Since the threads at both ends of the bidirectional lead screw are in opposite directions, the clamping blocks 204 at both ends will move in opposite directions, causing the grooves on the opposite sides of the clamping blocks 204 to disengage from the fixing ring 301 at the bottom of the sensor 3, thus releasing the fixing restriction at the bottom of the sensor 3. This completes the disassembly of the sensor 3. The entire replacement process does not require complicated tools, greatly shortening the maintenance time.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
