[0039] In this embodiment, the driving assembly controls the locking assembly to extend or retract by driving the transmission assembly to rotate, so that the lower tank body is close to the flange surface of the upper tank body or detached from the flange surface of the upper tank body, thereby achieving the purpose of locking or unlocking. This embodiment has a simple structure, is convenient and efficient, and the entire process can be unmanned, which significantly reduces personal injury. The expanded hole of the guide assembly can play a guiding role, allowing the docking of the flange surfaces of the lower tank body and the upper tank body to be more accurate, thereby improving the docking and locking efficiency.

[0040] Preferably, reference Figure 2 , the annular sleeve 11 on the mounting seat 1 can be made of a self-lubricating material; more preferably, the self-lubricating material can be copper;

[0041] Preferably, reference Figure 2 The mounting seat 1 further comprises: a mounting base plate 13; a bushing 14; the bushings 14 are respectively arranged and fixed on both sides of the sliding groove 11, and are made of self-lubricating material; more preferably, the bushings 14 are made of copper.

[0042] In the above embodiment, the annular sleeve on the mounting seat is made of self-lubricating material, which can make the transmission component rotate more smoothly, reduce the wear of the transmission component, and increase the service life of the entire tank docking locking device; a bushing made of self-lubricating material is arranged in the sliding groove on the mounting seat, which can make the locking component extend and retract more smoothly, reduce the wear of the locking component, and increase the service life of the locking component.

[0043] Preferably, reference Figure 2 and Figure 3 The mounting seat 1 also includes: a pressing plate 15; the pressing plate 15 is arranged between the mounting base plate and the transmission assembly 3, the pressing plate 15 passes through the annular sleeve 11, and is provided with a second hole; a plurality of mounting grooves 153 are arranged around the second hole of the pressing plate 15, the mounting groove 153 is located above the center of the sliding groove 11, and the center line points vertically to the center axis A1 of the first hole, and the number is consistent with the number of the sliding groove 11, and the width of the mounting groove 153 is slightly larger than the protrusion 41 of the locking assembly 4.

[0044] In the above embodiment, a pressure plate is arranged between the mounting seat and the transmission assembly to avoid direct friction between the transmission assembly and the mounting seat and thus causing wear. At the same time, the pressure plate is located above the sliding groove to prevent debris from above from falling into the sliding groove, thereby reducing wear and jamming of the sliding groove and improving the stability of the entire device.

[0045] More preferably, refer to Figure 3 The mounting groove 153 is through at the edge of the second hole to facilitate the installation of the locking assembly 4.

[0046] More preferably, refer to Figure 3 The pressure plate 15 also includes a plurality of cylindrical rollers 151 and a plurality of roller grooves 152. The number of the cylindrical rollers 151 and the roller grooves 152 are the same. The diameter of the roller grooves 152 is slightly larger than that of the cylindrical rollers 151, and the depth of the roller grooves 152 is smaller than that of the cylindrical rollers 151. The cylindrical rollers 151 can roll freely in the roller grooves 152, and the cylindrical rollers have arc protrusions of a certain height relative to the upper surface of the pressure plate 15.

[0047] In this embodiment, reference Figure 3 The pressure plate 15 is provided with a plurality of roller grooves and corresponding cylindrical rollers, and the sliding friction generated by the rotation of the transmission component relative to the pressure plate is converted into rolling friction between the transmission component and the cylindrical rollers. This allows the transmission component to rotate more smoothly, reduces resistance, and improves the mechanical efficiency of the device. Furthermore, the cylindrical rollers can be replaced regularly as wearing parts to increase the service life of the mounting seat and the transmission component.

[0048] More preferably, refer to Figure 1 and Figure 3 The mounting seat 1 further includes a plurality of step-shaped pressure plate brackets 16 disposed on the outer edge of the pressure plate 15, and the inner surface of the pressure plate bracket 16 is closely attached to the outer edge of the pressure plate 15 to prevent the pressure plate 15 from rotating.

[0049] In this embodiment, the pressure plate support 16 can avoid relative displacement between the pressure plate and the mounting seat to generate friction, and prevent the pressure plate from being driven by the transmission component to cause the locking component to get stuck, thereby improving the service life and stability of the entire device.

[0050] Preferably, the drive assembly 2 may be composed of a self-locking motor 21 and / or a manual drive 22;

[0051] Example, reference Figure 4The manual drive 22 is a device with a worm gear as the main body. By setting a driving wheel on the worm, manually rotating the driving wheel drives the turbine to rotate, thereby driving the transmission assembly 3 to rotate for driving. More preferably, the driving assembly 2 has a gear or / and a friction wheel on the driving shaft.

[0052] In the above embodiment, multiple driving modes are provided to drive the transmission assembly, so as to avoid the tank body docking and locking device being unusable due to a failure of one driving mode, thereby significantly improving the reliability of the tank body docking and locking device.

[0053] Preferably, reference Figure 5 and Figure 6 The outer edge of the transmission component 3 has teeth that match the driving component 2. It can be understood that the outer edge of the transmission component 3 can also be a friction surface to match the friction wheel on the driving shaft of the driving component 2.

[0054] Preferably, reference Figure 5 and Figure 6 The guide portion 43 on the locking assembly 4 is constructed as a cylinder, and the limiting groove 31 of the transmission assembly 3 is set as a cam groove corresponding to the guide portion 43; more preferably, the guide portion on the sliding assembly 4 can be additionally provided with a bearing to cooperate with the limiting groove 31 of the transmission assembly 3. More preferably, the limiting groove 31 can be an involute cam groove.

[0055] In the above-mentioned embodiment, the shape of the guide portion on the locking assembly and the limit groove on the transmission assembly can make the movement of the locking assembly smoother and more efficient; adding a bearing to the guide portion of the locking assembly can change the sliding friction of the locking assembly relative to the transmission assembly to rolling friction, thereby improving mechanical efficiency and increasing service life.

[0056] Preferably, the guide assembly 5 comprises a threaded hole 51, a conical expansion hole 52, and a ring seat 53. Figure 1 and Figure 7 A plurality of threaded holes 51 are arranged on the ring seat 53 and are evenly distributed; the guide assembly 5 is fixedly connected to the mounting seat 1 by bolt connection through the threaded holes 51. It can be understood that the conical generatrix of the inner surface of the conical expansion hole 52 can be set at different angles with the central axis A1 of the first hole.

[0057] In the above-mentioned embodiment, a plurality of threaded holes are provided on the guide assembly, which are connected to the mounting seat with bolts. The guide assembly is relatively fragile during use and can be easily replaced. A conical expansion hole is provided with a suitable angle between the busbar and the center axis A1 of the first hole, so that the guiding effect is more obvious when the lower tank body enters the first hole of the mounting seat.

[0058] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
