[0009] Preferably, an end of the sliding spring close to the pressure sensor is fixedly connected to an extrusion ring, and an end of the extrusion ring close to the pressure sensor is fixedly connected to an abutment pad, and the abutment pad is a rubber pad.

[0013] Preferably, a positioning buckle is fixedly connected to the upper surface of the handle, and the positioning buckle abuts against the limiting plate.

[0014] The effect achieved by the above components is: the positioning buckle is added to limit the range of motion of the limit plate, so that when the handle is pressed down, the sliding tube is driven to move directly downward to receive the extension rod therein.

[0015] Preferably, a driving structure is provided on one side of the assembly seat, and the driving structure includes an assembly bin, the assembly bin is fixedly connected to the assembly seat, the bottom wall of the assembly bin is fixedly connected to an electric motor, the output end of the motor is fixedly connected to a long rod, both ends of the long rod are respectively fixedly connected to a striking ball, the inner wall of the assembly bin is fixedly connected to two chassis, one end of the chassis close to the striking ball is fixedly connected to a return spring, the end of the return spring close to the striking ball is fixedly connected to a struck block, and the striking ball is consistent in height with the struck block.

[0017] Preferably, three sound outlet holes are provided on the upper surface of the assembly bin, and auxiliary blocks are fixedly connected to both sides of the chassis.

[0018] The effects achieved by the above components are: adding three sound holes can improve the sound effect, and the auxiliary blocks on both sides of the chassis can allow the impacted blocks to hit the auxiliary blocks during the left and right swing process, thereby increasing the frequency of the noise.

[0019] Preferably, a dustproof structure is provided on one side of the oil outlet, and the dustproof structure includes a fixing component and an auxiliary component, and the dustproof component includes a dustproof cover, the dustproof cover abuts against the oil outlet, and the dustproof cover is fixedly connected with three T-shaped plates on the side away from the oil outlet, and the dustproof rod is slidably connected with three clamping plates by means of the three T-shaped plates, and the arc surface of the dustproof cover is provided with three embedding grooves, and the positions of the embedding grooves correspond to the clamping plates, and the clamping plate is fixedly connected with an extrusion rod on the side away from the dustproof cover, and the dustproof rod is fixedly connected with a connecting pile on the side away from the oil outlet, and the dustproof cover is threadedly connected to the driving cover by means of the connecting pile, and the surface of the driving cover is provided with three extrusion holes, and the inner wall of the extrusion hole is slidably connected with the extrusion rod, and the auxiliary component includes a full package, and the full package is fixedly connected to the driving cover, and the full package is provided with three docking holes on a side close to the driving cover, and the positions of the docking holes correspond to the extrusion holes.

[0020] The effect achieved by the above components is: by adding a dustproof structure, the oil outlet of the manual oil unloading valve can have a dustproof cover in a very simple and quick way to prevent dust from sticking directly to the valve plate, so that the oil will not be contaminated by dust.

[0021] Preferably, the arc surface of the full package is provided with a plurality of anti-slip protrusions, and the anti-slip protrusions are rubber protrusions.

[0022] The effect achieved by the above components is that the addition of the anti-slip protrusions can increase the friction when the entire package is rotated, making the rotation more labor-saving.

[0023] Preferably, the arc surface of the dust cover is fixedly connected to a lever frame, and the lever frame is located above the arc surface of the dust cover.

[0024] The effect achieved by the above components is that the additional lever frame can fix the dust cover when rotating the drive cover and other components, thereby forming an opposite force and improving the adjustment efficiency.

[0025] Preferably, the method of use includes the following:

[0026] S1. To open and close the manual oil unloading valve, you need to turn the handle clockwise to move the valve stem backward with the fan-shaped teeth, so that the valve plate moves backward away from the oil outlet. During the rotation of the handle, the sliding buckle below is driven by the sliding tube to move along the sliding rod. By squeezing the sliding spring, the force applied by the squeezing ring on the pressure sensor is increased, so that the user can remotely obtain the opening and closing status of the manual oil unloading valve;

[0027] S2. When the manual oil unloading valve is found to be opened, the motor can be remotely started to drive the long rod to rotate. During the rotation of the long rod, the hitting ball repeatedly hits the hit block to make a sound, and the hit block can shake with the help of the reset spring. During the shaking process, it will hit the auxiliary blocks on both sides again to make a second sound;

[0028] S3. You can hold the lever to buckle the dust cover at the oil outlet, and then rotate the drive cover through the full package. The rotation of the drive cover will force the extrusion rod to slide along the extrusion hole to the other end in an extrusion manner. During this process, the three clip plates will be pulled inward until all of them are in contact with the oil outlet to complete the fixation.

[0029] Compared with the prior art, the advantages and positive effects of the present invention are:

[0030] 1. In the present invention, the process of using the manual oil unloading valve usually requires turning the handle clockwise to allow the fan-shaped teeth to move the valve stem backward, thereby causing the valve plate to move backward away from the oil outlet, and the oil can be unloaded. The manual oil unloading valve with a monitoring structure will drive the lower sliding buckle to move along the sliding rod through the sliding tube during the rotation of the handle, and by squeezing the sliding spring, the force applied by the squeezing ring to the pressure sensor is increased, so that the user of the tanker can remotely obtain the opening and closing state of the manual oil unloading valve, wherein the squeezing ring of the abutment pad can allow the spring to squeeze the pressure sensor more evenly, and the abutment pad made of rubber can also reduce the wear when contacting each other. By setting the monitoring structure, when the thief turns the handle, the sliding buckle of the monitoring component will slide on the sliding rod. This process will squeeze the sliding spring toward the pressure sensor, so that the force of the spring acting on the pressure sensor gradually increases, so that the user of the tanker can remotely obtain the opening and closing state of the manual oil unloading valve to avoid oil loss.

[0031] 2. In the present invention, when the handle is rotated to the middle gear, the long end needs to be pressed inward to allow the end close to the limit rod to tilt higher than the limit rod, and then pull it back to its original position to allow the handle to be clamped on the limit rod. During this process, the rotational connection between the connecting frame and the rotating rod, and the sliding connection between the extension rod and the sliding tube, can allow the handle to be pressed down and pulled back without being affected. The positioning buckle limits the movable range of the limit plate, so that when the handle is pressed down, it will drive the sliding tube to move directly downward to retract the extension rod therein, thereby improving the linkage effect. When the extension rod is completely retracted into the sliding tube, it is simply fixed with the help of the adsorption force of the magnetic plate and the magnetic ring. By setting a linkage component, the sliding buckle and the outer handle can move simultaneously without affecting the movable range of the handle itself.

[0032] 3. In the present invention, when the user finds through the monitoring structure that the manual oil unloading valve is opened, the motor can be remotely started to drive the long rod to rotate. During the rotation of the long rod, the hitting ball will repeatedly hit the two hit blocks. After being hit, the hit blocks will make a sound and shake with the help of the reset spring. During the shaking process, they will hit the auxiliary blocks on both sides again to make a secondary sound. The three sound holes can improve the sound effect. The auxiliary blocks on both sides of the chassis can hit the auxiliary blocks during the left and right swing of the hit blocks, so as to increase the frequency of the noise. By setting a driving structure, the noise is made by hitting the hit blocks, so as to alert the oil thieves, increase the pressure on the oil thieves, and force them to give up the head oil to achieve the driving effect.

[0033] 4. In the present invention, in order to prevent the valve plate from being stained with a lot of dust during the daily driving of the tank truck, the dust cover can be buckled at the oil outlet by holding the lever, and then the driving cover can be rotated through the full package. The rotation of the driving cover will force the extrusion rod to slide along the extrusion hole to the other end in an extrusion manner. During this process, the three clamping plates will be pulled inward until they are all abutted against the oil outlet to complete the fixation. The anti-slip protrusion can increase the friction when rotating the entire full package, making the rotation more labor-saving. By adding a dustproof structure, the oil outlet of the manual oil unloading valve can have a dustproof cover in a very simple and quick way to prevent dust from sticking directly to the valve plate, so that the oil will not be contaminated by dust.

The arc surface of the sliding rod 212 is slidably connected with a sliding buckle 213. The arc surface of the sliding rod 212 is sleeved with a sliding spring 214. The sliding spring 214 is located between the sliding buckle 213 and the pressure sensor 217. A sliding hole 218 is opened on the upper surface of the half shell 211. The linkage component 22 includes a connecting frame 221. The connecting frame 221 is fixedly connected to the upper surface of the sliding buckle 213.

[0055] The effect achieved by the entire monitoring structure 2 is that when the thief turns the handle 15, the sliding buckle 213 of the monitoring component 21 will slide on the sliding rod 212. This process will squeeze the sliding spring 214 toward the pressure sensor 217, so that the force of the spring acting on the pressure sensor 217 gradually increases, allowing the user of the tanker truck to remotely obtain the opening and closing status of the manual oil unloading valve to avoid oil loss.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Fig.11The driving structure 3 includes an assembly bin 31, which is fixedly connected to the assembly seat 11, the bottom wall of the assembly bin 31 is fixedly connected to the output end of the motor 32, and the two ends of the long rod 33 are respectively fixedly connected to striking balls 34, and the inner wall of the assembly bin 31 is fixedly connected to two chassis 35, one end of the chassis 35 close to the striking ball 34 is fixedly connected to a return spring 36, and the end of the return spring 36 close to the striking ball 34 is fixedly connected to a struck block 37, and the striking ball 34 is at the same height as the struck block 37, and three sound holes 39 are opened on the upper surface of the assembly bin 31, and auxiliary blocks 38 are respectively fixedly connected to the two sides of the chassis 35.

[0057] The whole driving structure 3 has the effect of making noise by striking the struck block 37, thereby alerting the oil thief, increasing the pressure on the oil thief, and forcing the other party to give up the hair oil to achieve the driving effect.

[0058] like Figure 1 , Figure 2 , Figure 3 , Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, the dustproof structure 4 includes a fixed component 41 and an auxiliary component 42, the dustproof component includes a dustproof cover 411, the dustproof cover 411 is abutted against the oil outlet 5, the dustproof cover 411 is fixedly connected to the side away from the oil outlet 5 with three T-shaped plates 413, the dustproof rod is slidably connected to three clamping plates 414 by means of the three T-shaped plates 413, the circular arc surface of the dustproof cover 411 is provided with three embedding grooves 412, the position of the embedding grooves 412 corresponds to the clamping plate 414, the clamping plate 414 is fixedly connected to the side away from the dustproof cover 411 with an extrusion rod 416, the dustproof rod is fixedly connected to the side away from the oil outlet 5 with a connecting pile 415, and the dustproof cover 411 is connected to the oil outlet 5 with the help of the connecting pile 415 is threadedly connected to a drive cover 417, and three extrusion holes 418 are provided on the surface of the drive cover 417.

The arc surface of the full package 421 is provided with a plurality of anti-slip protrusions 422, and the anti-slip protrusions 422 are rubber protrusions. The arc surface of the dust cover 411 is fixedly connected to a lever frame 424, and the lever frame 424 is located above the arc surface of the dust cover 411.

[0059] The effect achieved by the entire dustproof structure 4 is that the oil outlet 5 of the manual oil unloading valve can have a dustproof cover 411 in a very simple and quick manner to prevent dust from directly sticking to the valve plate 6 and prevent the oil from being contaminated by dust.

[0060] The usage includes the following:

[0061] S1. To open and close the manual oil unloading valve, the handle 15 needs to be turned clockwise to move the sector teeth 14 with the valve stem 12 backward, thereby causing the valve plate 6 to move backward away from the oil outlet 5. During the rotation of the handle 15, the sliding buckle 213 below is driven by the sliding tube 224 to move along the sliding rod 212. By squeezing the sliding spring 214, the force applied by the squeezing ring 215 to the pressure sensor 217 is increased, so that the user can remotely obtain the opening and closing status of the manual oil unloading valve;

[0062] S2. When the manual oil unloading valve is found to be opened, the motor 32 can be remotely started to drive the long rod 33 to rotate. During the rotation of the long rod 33, the striking ball 34 repeatedly hits the struck block 37 to make a sound, and the struck block 37 can shake with the help of the return spring 36. During the shaking process, it will hit the auxiliary blocks 38 on both sides again to make a second sound;

[0063] S3. You can hold the lever to buckle the dust cover 411 on the oil outlet 5, and then rotate the drive cover 417 through the full package 421. The rotation of the drive cover 417 will force the extrusion rod 416 to slide along the extrusion hole 418 to the other end in an extrusion manner. During this process, the three clamping plates 414 will be pulled inward until they are all abutted against the oil outlet 5 to complete the fixation.

[0064] The overall working principle is that, in the process of using the manual oil unloading valve, the handle 15 is usually turned clockwise to move the sector teeth 14 with the valve stem 12 backward, thereby moving the valve plate 6 backward away from the oil outlet 5, and the oil can be unloaded. The manual oil unloading valve with the monitoring structure 2 will drive the lower sliding buckle 213 to move along the sliding rod 212 through the sliding tube 224 during the rotation of the handle 15, and increase the force applied by the squeezing ring 215 to the pressure sensor 217 by squeezing the sliding spring 214, so that the user of the tanker can remotely obtain the opening and closing status of the manual oil unloading valve, wherein the pressure sensor 217 is pressed against the pressure sensor 217, and ... The extrusion ring 215 of the pad 216 can allow the spring to squeeze the pressure sensor 217 more evenly, and the rubber abutment pad 216 can also reduce the wear when they contact each other. By setting the monitoring structure 2, when the thief turns the handle 15, the sliding buckle 213 of the monitoring component 21 will slide on the sliding rod 212. This process will squeeze the sliding spring 214 toward the pressure sensor 217, so that the force of the spring acting on the pressure sensor 217 gradually increases, allowing the user of the tanker truck to remotely obtain the opening and closing status of the manual oil unloading valve to avoid oil loss.

[0065] Usually, when the handle 15 is rotated to the middle position, the long end needs to be pressed inward to make the end close to the limit rod 16 tilt higher than the limit rod 16, and then pull it back to its original position to allow the handle 15 to be clamped on the limit rod 16. During this process, the rotation connection between the connecting frame 221 and the rotating rod, and the sliding connection between the extension rod 223 and the sliding tube 224 can allow the handle 15 to be pressed down and pulled back without being affected. The positioning buckle 226 limits the movable range of the limit plate 225, so that when the handle 15 is pressed down, it will drive the sliding tube 224 to move directly downward to retract the extension rod 223 therein, thereby improving the linkage effect. When the extension rod 223 is completely retracted into the sliding tube 224, it is simply fixed with the help of the adsorption force of the magnetic plate 229 and the magnetic ring 228. By setting the linkage component 22, the sliding buckle 213 can move simultaneously with the outer handle 15 without affecting the movable range of the handle 15 itself.

[0066] When the user finds that the manual oil unloading valve is opened through the monitoring structure 2, the motor 32 can be remotely started to drive the long rod 33 to rotate. During the rotation of the long rod 33, the hitting ball 34 will repeatedly hit the two hit blocks 37. After being hit, the hit block 37 will make a sound and shake with the help of the reset spring 36. During the shaking process, it will hit the auxiliary blocks 38 on both sides again to make a secondary sound. The three sound holes 39 can improve the sound effect. The auxiliary blocks 38 on both sides of the chassis 35 can hit the auxiliary blocks 38 during the left and right swing of the hit block 37, so as to increase the frequency of the noise. By setting the driving structure 3, the noise is made by hitting the hit block 37, so as to alert the oil thief, increase the pressure on the oil thief, and force the other party to give up the head oil to achieve the driving effect.

[0067] In order to prevent the valve plate 6 from being stained with a lot of dust during the daily driving of the tanker truck, the dust cover 411 can be buckled on the oil outlet 5 by holding the lever, and then the driving cover 417 can be rotated through the full package 421. The rotation of the driving cover 417 will force the extrusion rod 416 to slide along the extrusion hole 418 to the other end in an extrusion manner. During this process, the three clamping plates 414 will be pulled inward until all of them are in contact with the oil outlet 5 to complete the fixation. The anti-slip protrusion 422 can increase the friction when rotating the entire full package 421, making the rotation more labor-saving. By adding the dustproof structure 4, the oil outlet 5 of the manual oil unloading valve can have a dustproof cover 411 in a very simple and quick way to prevent dust from sticking directly to the valve plate 6, so that the oil will not be contaminated by dust.
