[0026] Beneficial effects of the present invention:

[0027] (1) The present invention sleeves a male washer and a female washer on the middle section of the adjusting screw, and a plurality of radial grooves are evenly arranged on the bottom surface of the female washer, and two symmetrical protrusions are arranged on the same radial line of the top surface of the male washer. A support pressure quantitative adjustment component is arranged on the lower section of the adjusting screw. When the adjusting screw rotates clockwise, the female washer is fixed, and the male washer can rotate synchronously with the adjusting screw. Each time the protrusion moves from one radial groove to the next radial groove, the support pressure quantitative adjustment component transmits the support pressure to the tank support plate through the adjusting screw. Each time the protrusion moves to the next radial groove, the support pressure transmitted by the support pressure quantitative adjustment component increases by one unit. Therefore, according to the number of times the protrusion moves, the support pressure transmitted by the support pressure quantitative adjustment component to the tank support plate can be calculated, thereby achieving the effect of quantitatively adjusting the support pressure of the tank support plate;

[0028] (2) When the protrusion of the male washer of the present invention slides out from one radial groove of the female washer and moves to the next radial groove, the male washer and the female washer will produce a collision sound under the action of the spring pressure. The number of collisions between the male washer and the female washer can be used to determine the tank support plate support pressure generated by the spring pressure.

[0029] (3) Since the female washer and the male washer are designed to be concave and convex, when the protrusion is engaged in the radial groove, under the action of the spring pressure, the female washer and the male washer will not produce relative movement, which is equivalent to loading an anti-rotation force on the adjusting screw thread, ensuring that the support pressure after adjustment is very stable.

Therefore, they should not be understood as limitations on the present invention.

[0040] In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] See also Figure 1-6As shown, the embodiment of the present invention provides a quantified adjustment mechanism for the support pressure of a tank support assembly, including an adjustment screw 1, see Figure 3 As shown, the top thread of the adjusting screw 1 is sleeved with the tank support plate 2, and it is necessary to ensure that when the adjusting screw 1 rotates clockwise under the action of external force, the tank support plate 2 is fixed, and a number of circular holes are evenly arranged on the outer circumference of the tank support plate 2 to facilitate the fixing of the tank support plate 2 by the crowbar.

[0042] See also Figure 4 As shown, the middle section of the adjusting screw 1 is sleeved with a male washer 3 and a female washer 4, and the female washer 4 is stacked on the male washer 3, see Figure 3 As shown, the female washer 4 is fixed by the limit assembly, and the male washer 3 is fixedly connected to the adjusting screw 1 by the positioning pin 17, ensuring that when the adjusting screw 1 rotates clockwise, the female washer 4 is also fixed, and the male washer 3 can rotate synchronously with the adjusting screw 1; please refer to Figure 6 As shown, the bottom surface of the female gasket 4 is evenly provided with a plurality of radial grooves 41, see Figure 5 As shown, two symmetrical protrusions 31 are arranged on the same radial line on the top surface of the male washer 3, and the protrusions 31 match the radial grooves 41, see Figure 4 As shown, when the female washer 4 is stacked on the male washer 3, the two protrusions 31 are located in the corresponding two radial grooves 41.

[0043] See also Figure 3 As shown, a support pressure quantitative adjustment component is provided at the lower section of the adjusting screw 1. The support pressure quantitative adjustment component transmits the support pressure to the tank support plate 2 through the adjusting screw 1, so that the tank support plate 2 obtains the corresponding support pressure. It should be noted that when the adjusting screw 1 rotates clockwise, each time the protrusion 31 moves to the next radial groove 41, the support pressure transmitted by the support pressure quantitative adjustment component increases by a preset unit. Therefore, according to the number of movements of the protrusion 31, the support pressure transmitted by the support pressure quantitative adjustment component to the tank support plate 2 can be calculated, thereby achieving the effect of quantitatively adjusting the support pressure of the tank support plate 2.

[0044] See also Figure 3 , Figure 4 As shown, in a specific embodiment, the support pressure quantitative adjustment assembly includes a gear shaft 5, a sleeve 6, a guide screw 7 and a spring 8. The gear shaft 5 is sleeved on the lower section of the adjustment screw 1, and the gear shaft 5 is connected to the limit assembly. A transverse through hole is provided on the gear shaft 5, and a second bearing 16 is fixedly sleeved on the bottom of the gear shaft 5. The sleeve 6 is threadedly sleeved on the lower section of the adjustment screw 1, and the sleeve 6 is located below the male washer 3. A vertical keyway is provided on the outer periphery of the sleeve 6; the guide screw 7 is fixed in the transverse through hole, and the front section of the guide screw 7 is slidably engaged in the vertical keyway; the spring 8 is sleeved on the lower end of the adjustment screw 1.

[0045] Among them, the sleeve 6 and the spring 8 are both arranged in the installation cavity opened in the gear shaft 5, the top surface of the spring 8 is in contact with the bottom surface of the sleeve 6, and the bottom surface of the spring 8 is in contact with the bottom surface of the installation cavity. The spring 8 can freely expand and contract in the installation cavity.

[0046] Since the guide screw 7 is fixed in the transverse through hole of the gear shaft 5, and the shaft head of the guide screw 7 is inserted into the vertical keyway of the sleeve 6, when the adjusting screw 1 rotates clockwise, the sleeve 6 cannot rotate. Under the action of the thread of the adjusting screw 1, the sleeve 6 can only move downward under the guidance of the guide screw 7. The downward movement of the sleeve 6 will squeeze the spring 8 downward to generate spring 8 pressure. The spring 8 pressure reacts to the adjusting screw 1 to form a supporting pressure for the tank support plate 2. Therefore, by rotating the adjusting screw 1 to adjust the sleeve 6 to move up and down, the supporting pressure of the tank support plate 2 can be quantitatively adjusted.

[0047] See also Figure 3 As shown, in a specific embodiment, the limit assembly includes a clamping can shaft 9 and a cover body 10. The clamping can shaft 9 is threadedly sleeved on the upper section of the adjusting screw 1, the female washer 4 is fixedly installed on the bottom of the clamping can shaft 9 through the positioning pin 17, and the lower section of the clamping can shaft 9 is inserted into the gear shaft 5; the cover body 10 is sleeved on the top of the clamping can shaft 9, and the cover body 10 is fixedly connected to the bottom surface of the tank support plate 2; when the adjusting screw 1 rotates clockwise, the cover body 10 and the clamping can shaft 9 are also fixed.

[0048] For further information, see Figure 3 As shown, the limit assembly also includes a spindle nut sleeve 11, a No. 1 bearing 12, a gasket 13, a retaining spring 14 and a plunger 15. The top end of the spindle nut sleeve 11 is sleeved on the outer periphery of the upper section of the clamping can shaft 9, and the bottom end of the spindle nut sleeve 11 is sleeved on the outer periphery of the upper section of the gear shaft 5. When the adjusting screw 1 rotates clockwise, the spindle nut sleeve 11 is also fixed. The inner ring of the No. 1 bearing 12 is fixedly sleeved on the upper section of the gear shaft 5. The No. 1 bearing 12 is located below the spindle nut sleeve 11. A gasket 13 is arranged between the No. 1 bearing 12 and the spindle nut sleeve 11. The outer sleeve of the gasket 13 is sleeved with a retaining spring 14. The plunger 15 is sleeved on the outer periphery of the outer ring of the No. 1 bearing 12. The plunger 15 can rotate independently relative to the adjusting screw 1 and is not affected by the movement of the adjusting screw 1.

[0049] Working principle of the present invention:

[0050] When it is necessary to adjust the supporting pressure of the tank support plate 2, place a crowbar in the circular hole on the circumference of the tank support plate 2 to keep the tank support plate 2 stationary. When the tank support plate 2 is fixed, use an Allen wrench to rotate the adjusting screw 1 clockwise. Since the male washer 3 is fixed to the adjusting screw 1 by the locating pin 17, the sleeve 6 rotates with the adjusting screw 1. The adjusting screw 1 is threadedly connected to the sleeve 6. At the same time, there is a keyway on the sleeve 6, and the guide screw 7 is fixed in the transverse through hole of the gear shaft 5. The shaft head of the guide screw 7 is inserted into the vertical keyway of the sleeve 6. In this way, when the adjusting screw 1 rotates, the sleeve 6 cannot rotate. Under the action of the threads of the adjusting screw 1 and the sleeve 6, the sleeve 6 can only be guided downward by the guide screw 7, thereby driving the spring 8 to compress downward, generating spring 8 pressure, and the spring 8 pressure reacts to the adjusting screw 1 to form the supporting pressure of the tank support plate 2.

[0051] In this embodiment, eight evenly distributed radial grooves 41 are designed on the female gasket 4, and the pitch of the adjusting screw 1 is designed to be 2mm. Of course, according to the actual need of the tank support plate 2 for supporting pressure, other numbers of radial grooves 41 can also be designed, and the adjusting screw 1 can also be designed with other numerical pitches. In this embodiment, since the female gasket 4 is divided into eight equal parts, when the female gasket 4 and the male gasket 3 rotate one equal part relative to each other, it is equivalent to the adjusting screw 1 rotating 1 / 8 of a circle, thereby driving the sleeve 6 to move downward by 1 / 8X2mm=0.25mm, that is, the spring 8 is compressed downward by 0.25mm, and the stiffness of the spring 8 is designed to compress 0.25mm. It requires a pressure of 40N (it can also be designed to be other pressures as needed), which is equivalent to the tank support plate 2 generating a supporting pressure of 40N.

[0052] When the female washer 4 and the male washer 3 rotate relative to each other by one equal part, the protrusion 31 of the male washer 3 slides out from one radial groove 41 and moves to the next radial groove 41. Under the pressure of the spring 8, the male washer 3 and the female washer 4 will produce a collision sound. When the spring 8 is in a free state without pressure, the relative movement of the two will not produce a collision sound. By rotating the adjusting screw 1, the female washer 4 and the male washer 3 rotate relative to each other by one equal part, and a collision sound is produced, which is equivalent to the tank support plate 2 generating a support pressure of 40N. If a support pressure of 400N is required, just rotate the adjusting screw 1 clockwise until ten collision sounds are heard.

[0053] In addition, since the female washer 4 and the male washer 3 are designed to be concave and convex, when the protrusion 31 is engaged in the radial groove 41, under the pressure of the spring 8, the female washer 4 and the male washer 3 will not produce relative movement, which is equivalent to loading an anti-rotation force on the thread of the adjusting screw 1, that is, the adjusted support pressure is very stable.

[0054] The above is a detailed description of the preferred embodiments of the present invention, which cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
