DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] As shown in Figures 1-14 The present application provides a connecting device for a type IV bottle and a container, which comprises a first connecting piece for fixing a bottle mouth valve seat 8 of the type IV bottle on a top of the container, and a second connecting piece for fixing a bottom of the type IV bottle 1 on a bottom of the container, and the bottle mouth valve seat 8 can axially slide and circumferentially rotate in the first connecting piece.

[0045] The first connecting piece fixes the bottle mouth valve seat 8 of the type IV bottle 1 on the top of the container, and the second connecting piece fixes the bottom of the type IV bottle 1 on the bottom of the container, which achieves reliable fixation of both ends of the type IV bottle 1, avoids the problem that the type IV bottle 1 is damaged due to shaking during transportation because both ends of the type IV bottle 1 are not fixed in the container, and reduces damage to the type IV bottle 1 during transportation. Meanwhile, the first connecting piece in the present application enables the bottle mouth valve seat 8 to axially slide and circumferentially rotate in the first connecting piece, which not only avoids the problem that the type IV bottle 1 is easily damaged due to stress concentration because both ends of the type IV bottle 1 cannot circumferentially rotate due to complete fixation of the type IV bottle 1 to the container, but also avoids the problem that the type IV bottle 1 is easily damaged due to stress concentration because the type IV bottle 1 cannot axially deform during the inflation and deflation process due to complete fixation of the type IV bottle 1 to the container, thereby further reducing damage to the type IV bottle 1 during transportation.

[0046] In the present application, the circumferential rotation of the bottle mouth valve seat 8 in the first connecting piece specifically refers to slight rotation of one end of the type IV bottle 1 provided with the bottle mouth valve seat 8, and no rotation of one end of the type IV bottle 1 provided with a bottle bottom. The circumferential rotation is a slight rotation that cannot be observed by the naked eye. During the inflation and deflation process of the type IV bottle 1, the type IV bottle 1 is not completely axially deformed, but also accompanied by the circumferential rotation mentioned above.

[0047] As shown in Figures 1-4As shown in the drawings, the first connecting piece in the application is a sliding connecting ring 2, the inner ring of the sliding connecting ring 2 is used for sleeving the outside of the bottle port valve seat 8, and the outer ring of the sliding connecting ring 2 has an annular groove 9 fixedly connected with the top of the container. Among them, the sliding connecting ring 2 is sleeved on the outside of the bottle port valve seat 8, that is, the inner ring of the sliding connecting ring 2 is in sliding fit with the outside of the bottle port valve seat 8, which makes the end of the bottle port valve seat 8 of the type IV bottle 1 become a free end, and the end of the bottle port valve seat 8 of the type IV bottle 1 can axially slide and circumferentially rotate in the sliding connecting ring 2; at the same time, the annular groove 9 of the type IV bottle 1 is fixedly connected with the top of the container, which makes the sliding connecting ring 2 be fixed on the top of the container, and since the sliding connecting ring 2 is overlapped on the boss of the bottle port valve seat 8 and the bottle port valve seat 8 passes through the sliding connecting ring 2, the sliding connecting ring 2 limits the type IV bottle 1 in the up-down direction, so as to fix the end of the bottle port valve seat 8 of the type IV bottle 1 on the top of the container.

[0048] As shown in the drawings, Figures 1-2 , Figures 8-10 , Figures 21-22 As shown in the drawings, the bottom of the type IV bottle 1 in the application is provided with a plug seat 3, and the second connecting piece includes a connecting screw ring 4 arranged outside the plug seat 3, which is used for fixing the bottom of the type IV bottle 1 to the bottom of the container. The plug seat 3 is threadedly connected with the connecting screw ring 4, and the connecting screw ring 4 fixes the bottom of the type IV bottle 1 to the bottom of the container by cooperating with the bottom of the container.

[0049] Among them, the plug seat 3 in the application is integrally injection molded with the bottom of the type IV bottle 1, and the corresponding regions of the plug seat 3 and the bottom of the type IV bottle 1 are both provided with through holes for connecting the plug seat 3 and the bottom of the type IV bottle 1, one end of the plug seat 3 extends into the type IV bottle 1, the other end of the plug seat 3 extends out of the type IV bottle 1, and the other end of the plug seat 3 is connected with a plug 5 for sealing the bottom of the type IV bottle 1. Among them, the corresponding region of the bottom of the type IV bottle 1 refers to the region opposite to the through hole of the plug seat 3, the through hole of the bottom of the type IV bottle 1, and the through hole in the plug seat 3 are for facilitating processing, and the plug 5 plays a role of plugging the through hole of the bottom of the type IV bottle 1 and the through hole in the plug seat 3, and the end of the plug 5 facing the plug seat 3 is provided with a sealing ring for improving the sealing performance.

[0050] As shown in the drawings, Figures 21-22As shown, the upper part of the end plug seat 3 in the application is integrally injection molded with the bottom of the type IV bottle 1, the diameter of the bottom of the end plug seat 3 is not greater than the diameter of the bottom through hole of the container, so the application fixes the bottom of the type IV bottle 1 to the bottom of the container by screwing the connecting screw ring 4 with a diameter greater than the bottom through hole of the container to the bottom of the end plug seat 3 (the outer surface of the end plug seat 3 has external threads, and the inner circle of the connecting screw ring 4 has internal threads), so that the top of the container is just clamped between the upper end surface of the connecting screw ring 4 and the bottom of the end plug seat 3, and the bottom of the type IV bottle 1 does not shake.

[0051] Further, as shown in the drawings, Figures 11-12 The outer circle of the connecting screw ring 4 is provided with a plurality of fan-shaped protrusions, which are distributed along the circumference of the connecting screw ring 4. The adjacent fan-shaped protrusions form a gap, which facilitates the operator to rotate the connecting screw ring 4 by using a sleeve or other tools. The fan-shaped protrusions are located at the bottom of the container and protrude out of the bottom of the container, so that the operator can more conveniently rotate the connecting screw ring 4.

[0052] As shown in the drawings, Figures 15-22 The application also provides a type IV bottle 1 container using the above connecting device, which comprises a container frame 10 for loading and transporting the type IV bottle 1. The container frame 10 is a cuboid frame, which comprises a top frame 14 for fixed connection with the first connecting piece, a bottom frame 15 for fixed connection with the second connecting piece, and a stand 11 for connecting the top frame 14 and the bottom frame 15.

[0053] As shown in the drawings, Figures 13-14 In the application, a first bottle shoulder protective cover 6 for reducing damage to the type IV bottle 1 is arranged between the bottle mouth valve seat 8 and the top frame 14, and a second bottle shoulder protective cover 7 for reducing damage to the type IV bottle 1 is arranged between the bottom of the type IV bottle 1 and the bottom frame 15. The first bottle shoulder protective cover 6 and the second bottle shoulder protective cover 7 each comprise an inner bottle shoulder protective cover and an outer bottle shoulder protective cover, which are arranged in sequence from inside to outside and are connected. The inner bottle shoulder protective cover is a rubber protective cover, and the outer bottle shoulder protective cover is a plastic protective cover. Therefore, the first bottle shoulder protective cover 6 and the second bottle shoulder protective cover 7 in the application are supported by composite materials. The inner rubber protective cover plays a buffering and shock-absorbing role for the type IV bottle 1, and the outer plastic protective cover reduces the weight of the first bottle shoulder protective cover 6 and the second bottle shoulder protective cover 7, facilitating the carrying and installation of the first bottle shoulder protective cover 6 and the second bottle shoulder protective cover 7.

[0054] As shown in the drawings, Figures 15-17As shown, the top frame 14 in the present application comprises multiple rows of first connecting plates 17 and multiple columns of second connecting plates 18, the second connecting plates 18 are overlapped on the first connecting plates 17, each column of second connecting plates 18 has a breakpoint at the intersection position with the first connecting plate 17, a first connecting half ring 19 and a second connecting half ring 20 are respectively arranged on the adjacent two breakpoints, the first connecting half ring 19 and the second connecting half ring 20 are buckled to form a fixing member for fixing the first connecting member. Both ends of the first connecting plate 17 and the second connecting plate 18 are fixed on the connecting plate 21 which extends inwardly from the top frame 14 by bolts, and the second connecting plate 18 is fixed on the first connecting plate 17 by bolts, the inner diameter of the imaginary circle formed by the first connecting half ring 19 and the second connecting half ring 20 is smaller than the diameter of the sliding connecting ring 2, so that the sliding connecting ring 2 can be fixed on the top of the container by the first connecting half ring 19 and the second connecting half ring 20.

[0055] As shown, Figures 15-17 The first connecting half ring 19 and the second connecting half ring 20 have a gap between them for facilitating the operator to disassemble the second connecting plate 18, the four corners of the top frame 14 and the four corners of the bottom frame 15 are provided with corner members 16, the corner members 16 on the top frame 14 are used to be connected with the hoisting assembly, and the corner members 16 on the bottom frame 15 are used to be connected with the semitrailer; multiple first inclined struts 12 are further arranged on two opposite sides between the top frame 14 and the bottom frame 15, the first inclined struts 12 are distributed at intervals with the vertical column 11, and adjacent two first inclined struts 12 are symmetrically distributed with the vertical column 11 as the axis of symmetry (here, the vertical column 11 refers to the vertical column 11 located between the adjacent two first inclined struts 12); multiple second inclined struts 13 for improving the strength of the container frame 10 are arranged on the other two opposite sides between the top frame 14 and the bottom frame 15. The first inclined struts 12 and the second inclined struts 13 greatly improve the strength of the container frame 10, so that the container frame 10 is less likely to be deformed during transportation.
