A rotating block is threadedly connected to the arc surface of the fixed rod.

[0008] The effect achieved by the above components is as follows: The pressureless self-sealing venting nozzle of the filling gun body is a device specifically designed for liquid filling. It is usually used for filling operations without generating excessive pressure. However, the connection between the filling gun body and the filling tube is not very firm, and the connection between the two may loosen after long-term use. At this time, the filling tube and the filling gun body can be reinforced by adjusting the device. Thus, the stability of the filling tube and the filling gun body can be improved by adjusting the device.

[0009] Preferably, an auxiliary groove is provided on the side of the limiting groove away from the filling pipe.

[0010] The effect achieved by the above components is that when the locking block slides in the adjustment groove, the auxiliary groove opened on the adjustment groove can reduce the area of ​​direct contact between the adjustment groove and the locking block. Thus, under the action of the auxiliary groove, the friction between the locking block and the limiting groove can be reduced, and wear can be avoided.

[0011] Preferably, a contact pad is fixedly connected to the side of the rotating block near the adjusting frame, and the contact pad is in the shape of a ring.

[0012] The effect achieved by the above components is that when the rotating block rotates on the fixed rod and comes into contact with the adjustment frame, the contact pad installed on the rotating block can increase the friction between the rotating block and the adjustment frame, thereby improving the stability of the contact between the rotating block and the adjustment frame.

[0013] Preferably, the arc surface of the rotating block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the rotating block.

[0014] The effect achieved by the above components is that when the rotating block is rotated on the fixed rod, the anti-slip groove on the rotating block can increase the friction on the surface of the rotating block, thereby improving the efficiency of rotating the rotating block on the fixed rod through the anti-slip groove.

[0015] Preferably, the limiting rod is a titanium alloy rod.

[0016] The aforementioned components achieve the following effect: the limiting rod made of titanium alloy has a relatively hard surface, which makes it less likely for the limiting rod to deform even after long-term use, resulting in a better service life.

[0017] Preferably, the side of the filling valve is provided with an auxiliary device, which includes two fixing blocks. The two fixing blocks are respectively fixedly connected to both sides of the filling valve. A connecting rod is fixedly connected to the side of the fixing block away from the filling valve.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The present invention provides a pressureless self-sealing 15-degree venting nozzle filling gun, comprising: a filling gun body 1, a filling valve 4 installed on the inner wall of the filling gun body 1, a filling pipe 5 installed on one side of the filling gun body 1, an adjusting device 2 provided on the side of the filling gun body 1, and an auxiliary device 3 provided on the side of the filling valve 4.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting device 2 includes two connecting plates 201, which are fixedly connected to both sides of the dispensing gun body 1. An adjusting frame 203 is slidably connected to one side of each connecting plate 201. A fixing rod 202 is slidably connected to one inner wall of the adjusting frame 203. One end of the arc surface of the fixing rod 202 is fixedly connected to one side of the dispensing gun body 1. A sliding rod 204 is fixedly connected to the other inner wall of the adjusting frame 203. A moving plate 205 is slidably connected to the arc surface of the sliding rod 204. A limiting groove 208 is formed on the side of the moving plate 205. A limiting rod 206 is slidably connected to the inner wall of the limiting groove 208. One end of the arc surface of the limiting rod 206 is fixedly connected to one end of the arc surface of the dispensing tube 5. A locking block 207 is fixedly connected to the other end of the arc surface of 206. An adjusting groove 209 is provided on one side of the limiting groove 208. A rotating block 210 is threadedly connected to the arc surface of the fixing rod 202. The pressureless self-sealing venting nozzle body 1 is a device specifically designed for liquid dispensing. It is usually used for dispensing operations without generating excessive pressure. However, the connection between the dispensing nozzle body 1 and the dispensing tube 5 is not very firm, and the connection between the two may loosen after long-term use. At this time, the adjusting device 2 can be used to reinforce the connection between the dispensing tube 5 and the dispensing nozzle body 1. Thus, the adjusting device 2 can improve the stability of the fixing of the dispensing tube 5 and the dispensing nozzle body 1. The limiting groove 209 is provided on one side of the limiting groove 208. An auxiliary groove 211 is provided on the side away from the filling pipe 5. When the locking block 207 slides in the adjusting groove 209, the auxiliary groove 211 on the adjusting groove 209 can reduce the direct contact area between the adjusting groove 209 and the locking block 207. Therefore, under the action of the auxiliary groove 211, the friction between the locking block 207 and the limiting groove 208 can be reduced, avoiding wear. A contact pad 212 is fixedly connected to the side of the rotating block 210 near the adjusting frame 203. The contact pad 212 is circular. When the rotating block 210 rotates on the fixed rod 202 and comes into contact with the adjusting frame 203, the contact pad 212 installed on the rotating block 210 can increase the friction between the rotating block 210 and the adjusting frame 203, thereby... The contact pad 212 can improve the stability of the contact between the rotating block 210 and the adjusting frame 203. The arc surface of the rotating block 210 is provided with several anti-slip grooves 213. The anti-slip grooves 213 are evenly distributed on the arc surface of the rotating block 210. When the rotating block 210 is rotated on the fixed rod 202, the anti-slip grooves 213 on the rotating block 210 can improve the friction of the surface of the rotating block 210. Thus, the efficiency of rotating the rotating block 210 on the fixed rod 202 can be improved through the anti-slip grooves 213. The limiting rod 206 is a titanium alloy rod. The surface of the limiting rod 206 made of titanium alloy is relatively hard, which makes it difficult for the rod to deform even after long-term use, resulting in a better service life.

[0033] In the embodiments of this utility model, please refer to Figure 4The auxiliary device 3 includes two fixing blocks 31, which are fixedly connected to both sides of the filling valve 4. A connecting rod 36 is fixedly connected to the side of the fixing block 31 away from the filling valve 4. A telescopic rod 32 is fixedly connected to the side of the connecting rod 36 away from the fixing block 31. A spring 33 is fitted on the arc surface of the telescopic rod 32. The two ends of the spring 33 are fixedly connected to the connecting rod 36 and the telescopic rod 32, respectively. The ends of the two telescopic rods 32 away from the arc surface of the spring 33 are fixedly connected to the same connecting rod 34. A clamping plate 35 is fixedly connected to one end of the filling gun body 1. When using the filling gun body 1, the angle of the filling valve 4 of the filling gun body 1 can be limited by the auxiliary device 3. By limiting the angle, the personnel can be prevented from accidentally touching the filling valve 4, which would trigger the filling gun body 1. The arc surface of the connecting rod 34 is fixedly connected to the fixing sleeve 37. The arc surface of the fixing sleeve 37 is provided with anti-slip texture. When the connecting rod 34 comes into contact with the inner wall of the clamping plate 35, the fixing sleeve 37 installed on the connecting rod 34 can increase the friction when the connecting rod 34 comes into contact with the inner wall of the clamping plate 35, thereby improving the stability of the contact between the connecting rod 34 and the clamping plate 35.

[0034] The working principle of the pressureless self-sealing 15-degree venting nozzle filling gun provided by this utility model is as follows: After the filling tube 5 is connected to the filling gun body 1, the locking block 207 installed on the limiting rod 206 is connected to the adjusting groove 209. At this time, the moving plate 205 can be pressed on the sliding rod 204. At this time, the limiting rod 206 can be slid by pushing the moving plate 205 in the limiting groove 208. The movement of the moving plate 205 will drive the adjusting frame 203 to move. The movement of the adjusting frame 203 will move along the connecting plate 201. The fixing rod 202 installed on its inner wall will slide in the adjusting frame 203, moving the limiting rod 206 to one side of the inner wall of the limiting groove 208. At this time, the rotating block 210 can be rotated on the fixing rod 202 to fix the angle of the adjusting frame 203, thereby improving the fixing effect between the filling tube 5 and the filling gun body 1.

[0035] Press the connecting rod 34 toward the telescopic rod 32. Pressing the telescopic rod 32 will cause it to extend or retract. The movement of the telescopic rod 32 will cause the spring 33 to deform. At this time, the telescopic rod 32 will move the connecting rod 34 to one side of the clamping plate 35. Then the filling valve 4 can be released. The filling valve 4 can be reset by moving the connecting rod 36 through the fixing block 31. The telescopic rod 32 will then connect the connecting rod 34 to the inner wall of the clamping plate 35.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
