[0043] In this application, the terms "comprise", "include", "have" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0044] In this application, the term "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the separate existence of a centrifugal vortex magnetic pump, the simultaneous existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump, and the separate existence of a centrifugal vortex magnetic pump. Additionally, in this application, the character " / " generally indicates that the objects before and after are in an "and / or" relationship.

[0045] In this application, the terms "connect", "combine", "couple", "mount" can be direct connections, combinations, couplings or mounts, or indirect connections, combinations, couplings or mounts. Here, by way of example, a direct connection means that two parts or components are connected together without the need for an intermediate member, and an indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings and can include electrical connections or couplings.

[0046] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the stated value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances caused by manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. A relative term may refer to a plus or minus a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without a relative term should also be disclosed as a particular value with a tolerance. In addition, when expressing a relative angular position relationship (such as substantially parallel, substantially perpendicular), "substantially" may refer to a plus or minus a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0047] In the present application, those of ordinary skill in the art will understand that the functions performed by components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by parts can also be performed by one part, one component, or a combination of multiple parts.

[0048] In the present application, the orientation terms such as "upper", "lower", "left", "right", "front", and "rear" are described based on the orientation and positional relationship shown in the drawings, and should not be construed as a limitation on the embodiments of the present application.

For example, the lower side can include directly below, lower left, lower right, lower front, and lower rear, etc.

[0049] Please refer to Figures 1 to 3 , this embodiment provides a post-inflation device. The post-inflation device includes a frame body 1, an upper crossbeam mechanism 2, a lower crossbeam mechanism 3, a lifting lead screw 4, a lead screw nut (not marked in the figure), a worm gear (not marked in the figure), a worm 5, and a driving member 6. The lower crossbeam mechanism 3 is arranged on the frame body 1, and the upper crossbeam mechanism 2 and the lower crossbeam mechanism 3 can cooperate with each other to inflate the tire. The lifting lead screw 4 is slidably arranged on the frame body 1 in the vertical direction, and the upper crossbeam mechanism 2 is arranged at the lower end of the lifting lead screw 4. The lead screw nut is rotatably arranged on the frame body 1 and is in threaded cooperation with the lifting lead screw 4. The worm gear is coaxially sleeved on the lead screw nut. The worm 5 is rotatably arranged on the frame body 1 and meshes with the worm gear. The driving member 6 is arranged on the frame body 1, and the driving member 6 is configured to drive the worm 5 to rotate.

[0050] In practical applications, first place the tire on the lower crossbeam mechanism 3, and then the driving member 6 drives the worm 5 to rotate to drive the worm gear to rotate. Then, the worm gear drives the lead screw nut to rotate. Subsequently, the lead screw nut drives the lead screw to descend, and then the lead screw drives the upper crossbeam mechanism 2 to descend so that the upper crossbeam mechanism 2 is in a working position where it can cooperate with the lower crossbeam mechanism 3 to inflate the tire. Then, the upper crossbeam mechanism 2 and the lower crossbeam mechanism 3 cooperate with each other to inflate the tire. After vulcanization is completed, the driving member 6 drives the worm 5 to rotate in the reverse direction to drive the upper crossbeam mechanism 2 to reset.

[0051] It can be understood that the transmission structure composed of the worm gear, the worm 5, the lead screw nut, and the lifting lead screw 4, compared with the hydraulic transmission method in the prior art, will not affect the stability and safety due to reasons such as oil leakage and pipe explosion, thus making the stability and safety of the post-inflation device better, and further being able to avoid potential safety hazards in the tire production process. It should be noted that the upper crossbeam mechanism 2 and the lower crossbeam mechanism 3 are both well-known prior arts to those skilled in the art, so they will not be elaborated here. It should also be noted that the transmission structure composed of the worm gear and the worm 5 also has a self-locking structure, that is, the worm gear cannot drive the worm 5 to rotate, so that after the driving member 6 stops driving, the lead screw can stop at the current position, and thus there is no need for an additional structure to limit the position of the lead screw, with a simple structure and low usage cost.

[0052] Preferably, the driving member 6 is a servo motor, and the output shaft of the servo motor is coaxially connected to the worm 5. It can be understood that using a servo motor to drive the worm 5 to rotate is efficient, energy-saving, and has stable operation. It should be noted that the model of the servo motor is selected according to the actual application scenario, and this embodiment does not make specific requirements and limitations on this. It should also be noted that in other embodiments, the driving member 6 can also adopt any one of the existing technologies with a rotational driving function, which will not be elaborated here.

[0053] To improve the smoothness of the sliding of the upper crossbeam mechanism 2, the post-inflation device further includes a guiding assembly 7. The guiding assembly 7 is arranged on the frame body 1, and the guiding assembly 7 is configured to guide the lifting of the upper crossbeam mechanism 2. Specifically, the guiding assembly 7 includes a sliding sleeve 71, a sliding rod 72, and a connecting member 73. The sliding sleeve 71 is arranged on the frame body 1. The sliding rod 72 is in sliding fit with the sliding sleeve 71, and the lower end of the sliding rod 72 is connected to the upper crossbeam mechanism 2. The lower end of the sliding rod 72 is connected to the upper crossbeam mechanism 2 through the connecting member 73. Further, the guiding assembly 7 further includes a strengthening member 74, and the strengthening member 74 is arranged on the connecting member 73. With such a setting, the structural strength of the connecting member 73 can be improved.

[0054] Preferably, the frame body 1 includes an upper crossbeam 11, a lower crossbeam 12, and a connecting rod 13. The lifting lead screw 4, the lead screw nut, the worm gear, the worm 5, and the driving member 6 are all arranged on the upper crossbeam 11. The lower crossbeam 12 is located directly below the upper crossbeam 11, and the lower crossbeam mechanism 3 is arranged on the lower crossbeam 12. The upper crossbeam 11 and the lower crossbeam 12 are connected into one body through the connecting rod 13. With such a setting, the structure of the frame body 1 can be made more compact and the usage cost can be lower. In this embodiment, the upper crossbeam 11 and the lower crossbeam 12 are preferably hollow square tubes in the prior art, so as to reduce the weight of the frame body 1 and facilitate the assembly and handling of the frame body 1.

[0055] Further, there are two connecting rods 13, and the same-side ends of the upper crossbeam 11 and the lower crossbeam 12 are connected into one body through the same connecting rod 13. With such a setting, the frame body 1 is a square frame structure with higher structural strength.

[0056] It should be noted that in this embodiment, the structures of the two connecting rods 13 are the same. Hereinafter, the structure of one of the connecting rods 13 will be taken as an example for description. The connecting rod 13 includes a rod body 131, a first connecting portion 132, a first nut 133, a second connecting portion 134, and a second nut 135. The first connecting portion 132 is disposed at the upper end of the rod body 131. The first connecting portion 132 can pass through the end of the upper cross beam 11 and be screwed to the first nut 133, so as to respectively abut against both sides of the upper cross beam 11 through the first nut 133 and the upper end surface of the rod body 131. The second connecting portion 134 is disposed at the lower end of the rod body 131. The second connecting portion 134 can pass through the end of the lower cross beam 12 and be screwed to the second nut 135, so as to respectively abut against both sides of the lower cross beam 12 through the second nut 135 and the lower end surface of the rod body 131.

[0057] Furthermore, the connecting rod 13 further includes a first gasket 136, a second gasket 137, a third gasket 138, and a fourth gasket 139. The first gasket 136 is disposed between the first nut 133 and the upper cross beam 11. The second gasket 137 is disposed between the upper end surface of the rod body 131 and the upper cross beam 11. The third gasket 138 is disposed between the second nut 135 and the lower cross beam 12. The fourth gasket 139 is disposed between the lower end surface of the rod body 131 and the lower cross beam 12. It can be understood that the setting of the first gasket 136 can increase the contact area between the first nut 133 and the upper cross beam 11, thereby improving the connection strength between the first nut 133 and the upper cross beam 11. The setting of the second gasket 137 can increase the contact area between the upper end surface of the rod body 131 and the upper cross beam 11, thereby improving the connection strength between the upper end surface of the rod body 131 and the upper cross beam 11. The setting of the third gasket 138 can increase the contact area between the second nut 135 and the lower cross beam 12, thereby improving the connection strength between the second nut 135 and the lower cross beam 12. The setting of the fourth gasket 139 can increase the contact area between the lower end surface of the rod body 131 and the lower cross beam 12, thereby improving the connection strength between the lower end surface of the rod body 131 and the lower cross beam 12. It should be noted that the models of the first gasket 136, the second gasket 137, the third gasket 138, and the fourth gasket 139 are all selected according to the actual application scenario, and this embodiment does not make specific requirements and restrictions on this.

[0058] This embodiment further provides a tire production device, which includes the above-mentioned post-inflation device. It can be understood that the tire production device including the post-inflation device has better stability and safety, and thus can avoid potential safety hazards during the tire production process.

[0059] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
