Description

Technical Field

[0001] The utility model relates to the technical field of weighbridge junction boxes, in particular to a Bluetooth weighbridge box. Background Art

[0002] The plastic junction box of a floor scale is usually composed of a box body, a box cover, a circuit board, wiring terminals, and waterproof wire studs. The wiring terminals and circuit board are arranged in the box body, and the lower end of the wiring terminals is fixed on the circuit board. The box cover cooperates with the sealing ring to cover the box body to achieve a sealed and fixed connection. In addition, in order to protect the AD analog-to-digital conversion chip to work normally in harsh environments, the circuit board needs to be sealed with glue.

[0003] However, during the installation of the existing weighbridge junction box, in order to facilitate the wiring operation between the weighbridge junction box and the weighbridge, a pit connected to the weighbridge installation pit is generally excavated in the middle part of one side of the weighbridge installation pit, the weighbridge junction box is installed inside the pit, and a steel plate is set above it to cover it to prevent foreign objects from falling in and to provide certain protection for the weighbridge junction box. However, since the weighbridge junction box is installed below the ground and the interior of the pit is relatively flat to ensure the stability of the weighbridge junction box, water is easily accumulated inside the pit when it rains. At the same time, when it rains, rainwater mixes with soil to form muddy water , it will also flow into the pit, causing not only accumulated water in the pit to soak the scale junction box, but also silt to wrap the scale junction box after the accumulated water dissipates, causing the accumulated water to enter from the gaps in the scale junction box and the gaps between the scale junction box and the wiring harness, corroding the circuits inside the scale junction box. At the same time, the scale junction box will also be corroded by the silt, causing water to enter or corrode the inside of the scale junction box, causing damage to the scale junction box, thereby seriously affecting the service life of the scale junction box. Therefore, a scale box is proposed that can prevent the scale junction box from being soaked in water and corroded by silt when it rains. Utility Model Content

DETAILED DESCRIPTION

[0025] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0026] See also Figure 1-6The utility model provides a technical solution: a Bluetooth floor scale box, comprising a cover plate 3 installed inside a concrete pavement 1, a mounting groove 7 being opened on the surface of the concrete pavement 1, the inner bottom wall of the mounting groove 7 being an inclined surface, the mounting groove 7 being connected to the pit at the installation position of the floor scale, so that when it rains, the rainwater in the mounting groove 7 can flow into the installation pit of the floor scale, avoiding the possibility of rainwater retention in the mounting groove 7, the cover plate 3 being mounted in the installation groove 7, a floor scale junction box 4 being provided at the bottom of the cover plate 3, the floor scale junction box 4 being also located in the mounting groove 7, both sides of the floor scale junction box 4 being fixedly connected with rubber sleeves 5 arranged at equal distances, a wiring harness being placed on the inner wall of the rubber sleeve 5, and the wiring harness can preferably be a spring wire so that the wiring harness can be stretched.

[0027] The surface of the concrete pavement 1 is provided with a water collecting trough 2 connected to the mounting groove 7. The inner wall of the water collecting trough 2 is inclined to collect and guide rainwater. The inner wall of the water collecting trough 2 is rotatably connected to a rotating shaft 11. The surface of the rotating shaft 11 is sleeved with a winding roller 12. The surface of the winding roller 12 is fixedly connected to a traction rope 6. The end of the traction rope 6 away from the winding roller 12 is fixedly connected to the surface of the scale junction box 4. A pulley 17 is mounted on the bottom of the cover plate 3. The surface of the traction rope 6 and the surface of the pulley 17 slide with each other to bend the traction rope 6 so that the scale junction box 4 can better withstand the pulling force of the traction rope 6 on the scale junction box 4.

[0028] Furthermore, a baffle 13 is fixedly connected to the surface of the rotating shaft 11, so that through the setting of the baffle 13, the rotating shaft 11 can be driven to rotate under the impact of rainwater in the water collecting trough 2 on the baffle 13, thereby providing power for the rise of the bridge scale junction box 4 in the installation groove 7. The inner wall of the winding roller 12 is provided with card grooves 14 arranged at equal distances around the circumference, and the interior of the rotating shaft 11 is slidably connected with card blocks 15 arranged at equal distances around the circumference. The surface of the card block 15 slides with the inner wall of the card groove 14. The end of the card block 15 located inside the card groove 14 is tapered, and the surface of the card block 15 is fixedly connected to the first A spring 16, one end of the first spring 16 away from the block 15 is fixedly connected to the inside of the rotating shaft 11, for resetting the block 15, so that the rotating shaft 11 and the winding roller 12 can slide against each other through the arrangement of the block 15, the first spring 16 and the card slot 14. When the local scale junction box 4 cannot rise in the installation slot 7, the rotating shaft 11 can still be driven to continue to rotate under the impact of the water flow on the baffle 13, thereby avoiding the situation where the rotating shaft 11 cannot rotate, causing the baffle 13 to cover the inner wall of the water collecting tank 2, making it impossible for the water flow to be discharged, affecting the use of the device.

[0029] The surface of the weighbridge junction box 4 is fixedly connected to a vent 8 which is connected to the inside of the weighbridge junction box 4. Through the setting of the vent 8, the heat in the weighbridge junction box 4 can be dissipated to the outside, and the inside of the weighbridge junction box 4 is dissipated. At the same time, the setting of the vent 8 increases the height of the heat dissipation position of the weighbridge junction box 4, so that rainwater cannot enter the weighbridge junction box 4 during rain, thereby avoiding damage to the weighbridge junction box 4.

[0030] The lower end of the extrusion rod 20 is fixedly connected to the lower end of the extrusion rod 20, and the upper end of the extrusion rod 20 is fixedly connected to the lower end of the extrusion rod 18. The U-shaped extrusion blocks 9 are slidably connected to both sides of the interior of the scale junction box 4, and the upper side of the extrusion block 9 is an inclined surface. The surface of the extrusion block 9 contacts the surface of the rubber sleeve 5 located inside the scale junction box 4, and the lower end of the extrusion rod 20 contacts the inclined surface of the extrusion block 9. When the scale junction box 4 rises, the cover plate 3 is used to squeeze the lifting rod 18, driving the extrusion rod 20 to squeeze the inclined surface of the extrusion block 9, so that the extrusion block 9 squeezes and pushes the rubber sleeve 5, so that the rubber sleeve 5 is squeezed and compressed, thereby filling and sealing the gap between the rubber sleeve 5 and the scale junction box 4 and the gap between the inner wall of the rubber sleeve 5 and the wiring harness again, thereby avoiding rainwater from entering the scale junction box 4, thereby improving the waterproof effect of the scale junction box 4, which is worthy of promotion.

[0031] A second spring 19 is movably sleeved on the surface of the lifting rod 18, and the two ends of the second spring 19 are fixedly connected to the inner wall of the ventilator 8 and the surface of the lifting rod 18 respectively, so as to reset the lifting rod 18. A Bluetooth module 10 is fixedly connected to the interior of the weighing scale junction box 4, and through the setting of the Bluetooth module 10, the user can connect the recycling system to the weighing scale junction box 4 via Bluetooth, so that the device can be quickly connected to the recycling system, thereby improving the convenience of using the weighing scale junction box 4.

[0032] The water flows through the water collecting trough 2 and flows into the mounting groove 7, and at the same time impacts the baffle 13, thereby driving the rotating shaft 11 and the winding roller 12 to rotate, so that the winding roller 12 reels the traction rope 6, and then drives the scale junction box 4 to rise in the mounting groove 7, thereby driving the vent tube 8 and the lifting rod 18 to rise, so that the lifting rod 18 contacts the bottom of the cover plate 3, and then presses the lifting rod 18 into the vent tube 8, so that the extrusion rod 20 squeezes the inclined surface of the extrusion block 9, pushing the extrusion block 9 to slide in the scale junction box 4, compressing the rubber sleeve 5, and further closing the gap between the rubber sleeve 5 and the scale junction box 4 and the rubber sleeve 5 and the wiring harness. At the same time, when it rains, the height of the scale junction box 4 in the mounting groove 7 can be lifted, so that the scale junction box 4 does not come into contact with too much rainwater, thereby reducing the possibility of water entering the scale junction box 4, improving the waterproof effect of the scale junction box 4, and improving the service life of the scale junction box 4, which is worthy of promotion.

[0033] At the same time, after the water flow in the water collecting trough 2 impacts the baffle 13, it flushes the inner bottom wall of the installation groove 7, thereby avoiding the generation of silt on the inner bottom wall of the installation groove 7, resulting in more silt being generated inside the subsequent installation groove 7, thereby corroding the floor scale junction box 4 and reducing the service life of the floor scale junction box 4.

[0034] When the local scale junction box 4 can no longer rise in the installation groove 7, that is, when the winding roller 12 can no longer reel in the traction rope 6, the rotating shaft 11 drives the clamping block 15 to rotate, and the inner wall of the clamping groove 14 squeezes the inclined surface of the clamping block 15, driving the clamping block 15 to retract into the rotating shaft 11, so that the rotating shaft 11 can slide with the clamping groove 14, so that the water flow can smoothly drive the rotating shaft 11 to rotate, avoiding obstruction of the flow of rainwater and the occurrence of water accumulation.

[0035] Working principle: When it rains, water flows through the water collection trough 2 and flows into the installation groove 7, while impacting the baffle 13, thereby driving the rotating shaft 11 and the winding roller 12 to rotate, so that the winding roller 12 reels the traction rope 6, and then drives the scale junction box 4 to rise in the installation groove 7, thereby driving the ventilator 8 and the lifting rod 18 to rise, so that the lifting rod 18 contacts the bottom of the cover 3, and then presses the lifting rod 18 into the ventilator 8, so that the extrusion rod 20 squeezes the inclined surface of the extrusion block 9, pushing the extrusion block 9 to slide in the scale junction box 4, compressing the rubber sleeve 5, and further closing the gap between the rubber sleeve 5 and the scale junction box 4 and the rubber sleeve 5 and the wiring harness.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
