Description

Technical Field

[0001] The utility model belongs to the technical field of urea filling machines, and particularly relates to a safety locking device for a urea filling machine. Background Technique

[0002] Vehicle urea solution is a transparent and clear liquid, which is composed of 32.5% high-purity urea and 67.5% deionized water, and is used to reduce nitrogen oxides. Vehicle urea is also known as diesel exhaust treatment fluid. There is a separate urea tank on the truck to store vehicle urea solution. When the engine starts to work, the ECU accurately measures the injection volume of the urea solution according to the working conditions of the diesel engine, the temperature of the catalytic converter and the environmental state. The urea solution is injected into the intake pipe, uniformly mixed with the diesel exhaust and undergoes a chemical reaction. Its function is to reduce nitrogen oxide emissions.

[0003] Therefore, it is necessary to regularly fill the urea tank of the vehicle to ensure normal use. When filling the urea tank of the vehicle, it is usually necessary to insert the filling gun of the urea filling machine into the filling port of the vehicle's urea tank for filling. However, since the diameter of the filling barrel 1 of the filling gun is much smaller than the filling port of the urea tank, and the filling gun is relatively heavy, holding the filling gun all the time will cause fatigue. And directly placing the filling gun on the filling port of the urea tank is likely to cause shaking and the risk of falling under the reaction force during filling. For this reason, we propose a safety locking device for a urea filling machine to solve the above-mentioned problems. Summary of the Utility Model

Specific embodiments

[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 4, the present utility model provides a safety locking device for a urea filling machine, which includes a filling gun head 3. At the end of the filling gun head 3, there is a filling gun barrel 1. A locking component 2 is provided at the connection between the filling gun barrel 1 and the filling gun head 3. The locking component 2 includes two mounting plates 9. At both ends of the two mounting plates 9, connecting frames 10 are fixed by bolts. On one side of the two connecting frames 10, a plurality of sliding holes 15 are opened. A sliding frame 11 is slidably connected in the sliding holes 15. At one end of the two sliding frames 11, a clamping seat 6 for clamping and locking with the urea tank filling port of the vehicle is fixed by bolts. A plurality of springs 5 are fixed by bolts between the clamping seat 6 and the connecting frame 10. In both of the two connecting frames 10, there is a pressing component for secondary fixing of the clamping seat 6. When filling urea into the urea tank of the vehicle, usually, the filling gun of the urea filling machine needs to be inserted into the filling port of the urea tank of the vehicle for filling. However, since the diameter of the filling gun barrel 1 of the filling gun is much smaller than the filling port of the urea tank, and the filling gun is relatively heavy, holding the filling gun all the time will cause fatigue. And directly placing the filling gun on the filling port of the urea tank is likely to cause shaking and the risk of falling under the reaction force during filling. Therefore, the locking component 2 is used to fix the filling gun. When in use, first, the filling gun barrel 1 is inserted into the filling port of the urea tank. Then, under the elastic force of the spring 5, the two clamping seats 6 clamp the outside of the filling port of the urea tank, so that the filling gun head 3 is initially fixed. Then, through the pressing component, the clamping seat 6 is further pressurized, so that the clamping seat 6 is clamped more stably and is applicable to the filling ports of urea tanks of different sizes, thus effectively solving the above problems. On both sides of the inner walls of the two connecting frames 10, fixing ribs 4 are fixed by bolts, and the fixing ribs 4 are fixed to the mounting plates 9, further improving the stability between the connecting frames 10 and the mounting plates 9. On one side of the two mounting plates 9, a plurality of uniformly distributed mounting holes 8 are opened, so as to facilitate the installation of the mounting plates 9 to the connection between the filling gun barrel 1 and the filling gun head 3 through the mounting holes 8.

[0026] In the present utility model, on one side of each of the two clamping seats 6, a slope 13 is opened, and the slopes 13 are all located outside the clamping seats 6. Through the slopes 13, it is convenient to clamp the clamping seats 6 outside the filling port of the urea tank.

[0027] In the present utility model, on the inner walls of the two clamping seats 6, a plurality of card slots 14 are opened, and the plurality of card slots 14 are evenly distributed, so as to facilitate the connection of the clamping seats 6 with the threads outside the filling port of the urea tank through the card slots 14.

[0028] In the present utility model, the pressing component is a threaded cylinder 7 and a lead screw 12, and the threaded cylinder 7 and the lead screw 12 are in threaded connection. The threaded cylinder 7 is fixed to one side of the connecting frame 10 by bolts. At the end of the lead screw 12 away from the clamping seat 6, a plurality of dial rods 16 are fixed by bolts, and the plurality of dial rods 16 are equidistantly distributed. Thus, by rotating the dial rods 16, the lead screw 12 rotates and moves inwards along the threaded cylinder 7, and presses the clamping seat 6.

[0029] In the present utility model, a rotating pressure block 17 is rotatably connected to one end of the lead screw 12 close to the clamping seat 6, so that the lead screw 12 can still perform micro-rotation when contacting the clamping seat 6 through the rotating pressure block 17, and the extrusion is more effective. A rubber pad 18 is bonded to the side of the rotating pressure block 17 close to the clamping seat 6, so that the rubber pad 18 not only increases the friction between the rotating pressure block 17 and the clamping seat 6, but also effectively reduces the collision wear between the rotating pressure block 17 and the clamping seat 6.

[0030] The working principle and usage process of the present utility model: When in use, first insert the filling gun barrel 1 into the filling port of the urea tank. Through the slope 13, it is convenient to clamp the clamping seat 6 outside the filling port of the urea tank. Then, under the elastic force of the spring 5, the two clamping seats 6 clamp the outside of the filling port of the urea tank, so that the filling gun head 3 is initially fixed. Then, by rotating the lever 16, the lead screw 12 rotates and moves inward along the threaded barrel 7, and presses the clamping seat 6. At this time, through the rotating pressure block 17, the lead screw 12 can still perform micro-rotation when contacting the clamping seat 6, and the extrusion is more effective. Moreover, the rubber pad 18 not only increases the friction between the rotating pressure block 17 and the clamping seat 6, but also effectively reduces the collision wear between the rotating pressure block 17 and the clamping seat 6, so that the clamping seat 6 is further pressurized, and the clamping seat 6 is clamped more stably. Furthermore, it effectively solves the problem that since the diameter of the filling gun barrel 1 of the filling gun is much smaller than the filling port of the urea tank and the filling gun is relatively heavy, holding the filling gun all the time will cause fatigue, and directly placing the filling gun at the filling port of the urea tank is likely to shake and fall under the reaction force during filling.

[0031] The electronic components and modules used in the content of this utility model can all be parts commonly used in the current market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
