[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 5 As shown, this embodiment proposes a tire-assisted fixing mechanism for a tire changer, including a base 1, clamping blocks 2, support blocks 3, locking components 4, spring-loaded components 5, limiting components 6, and a drive component 7. Three mounting slots are provided on the upper end of the base 1. Three clamping blocks 2 are mounted on the upper end of the base 1, arranged circumferentially and evenly. Three support blocks 3 are slidably connected to the upper ends of the three mounting slots. The locking component 4 is installed inside the support blocks 3. The spring-loaded components 5 are installed on opposite sides of the three mounting slots. The limiting components 6 are installed on the upper ends of the mounting slots. The drive component 7 is installed inside the base 1. After the clamping blocks 2 are installed inside the support blocks 3, the drive component 7 drives the support blocks 3 to slide under the restriction of the limiting components 6. Under the push of the spring force within the spring-loaded components 5, the locking component 4 inside the support blocks 3 is pushed to lock the clamping blocks 2, maintaining stability when fixing the tire. When the clamping blocks 2 are locked, the drive component 7 continuously pushes the support blocks 3, causing the clamping blocks 2 to move away from each other, clamping and fixing the tire from the inside.

[0030] The locking assembly 4 comprises a sliding groove 41, a sliding block 42, a connecting groove 43, a locking rod 44, a plug groove 45, a plug block 46 and a locking groove 47. The sliding groove 41 is arranged at the lower end of the supporting block 3. The sliding block 42 is slidingly connected inside the sliding groove 41. The connecting groove 43 is arranged at the upper end inside the sliding groove 41. The connecting groove 43 is L-shaped. The locking rod 44 is slidingly connected inside the connecting groove 43. The locking rod 44 is fixedly connected to the upper end of the sliding block 42. The plug groove 45 is arranged at the upper end of the supporting block 3. The plug groove 45 penetrates the connecting groove 43. The plug block 46 is inserted into the plug groove 45. The plug block 46 is fixedly connected to the lower end of the clamping block 2. The locking groove 47 is arranged at one side of the plug block 46. The locking rod 44 is inserted into the locking groove 47. When the driving assembly 7 is not driven, the locking rod 44 is accommodated inside the connecting groove 43. The clamping block 2 is installed by inserting the plug block 46 into the locking groove 47. When the driving assembly 7 is driven, the supporting block 3 does not slide at the initial stage under the elastic force of the rebound assembly 5. The sliding block 42 slides inside the sliding groove 41 to drive the locking rod 44 to slide inside the connecting groove 43. One end of the locking rod 44 is inserted into the locking groove 47. The plug block 46 is locked inside the plug groove 45 to keep the clamping block 2 stable. At this time, the sliding block 42 slides to one end of the sliding groove 41. The sliding block 42 pushes the supporting block 3 to slide. The supporting block 3 drives the clamping block 2 to move away from each other to clamp and fix the tire from the inside.

[0031] The rebound assembly 5 comprises an accommodation groove 51, a limiting rod 52 and a spring 53. The accommodation groove 51 is arranged at the sides of the three mounting grooves away from each other. The limiting rod 52 is fixedly connected to the ends of the three supporting blocks 3 away from each other. The spring 53 is installed inside the accommodation groove 51. The spring 53 is sleeved outside the limiting rod 52. The spring 53 provides a pushing force. The locking rod 44 is accommodated inside the connecting groove 43 when the driving assembly 7 is not driven under the elastic force of the spring 53. The spring 53 is limited by the accommodation groove 51 and the limiting rod 52.

[0032] The limiting assembly 6 comprises a limiting groove 61 and a limiting block 62. The limiting groove 61 is arranged at the two sides inside the mounting groove. The limiting block 62 is slidingly connected inside the limiting groove 61. The limiting block 62 is fixedly connected to the two sides of the supporting block 3. The limiting assembly 6 keeps the supporting block 3 stable when sliding inside the mounting groove.

[0033] The driving assembly 7 comprises a hydraulic rod 71, a connecting plate 72 and a supporting rod 73. The hydraulic rod 71 is fixedly connected inside the base 1. The connecting plate 72 is fixedly connected to the upper end of the hydraulic rod 71. The supporting rod 73 is hinged to the middle part of the lower end of the sliding block 42. The supporting rod 73 is hinged to the outer side of the connecting plate 72. The hydraulic rod 71 pushes the connecting plate 72 to move up and down. The linear motion of the connecting plate 72 is converted into the linear motion of the sliding block 42 under the connection of the supporting rod 73.

[0034] In use, when the driving assembly 7 is not driven, the locking rod 44 is accommodated inside the connecting groove 43, the plug block 46 is inserted inside the locking groove 47, the clamping block 2 is installed, the connecting plate 72 is pushed to move upward by the hydraulic rod 71, the linear motion of the connecting plate 72 is converted into the linear motion of the sliding block 42 under the connection of the supporting rod 73, the spring 53 in the rebound assembly 5 exerts the elastic force to support the clamping block 3 to not slide at the beginning, the sliding block 42 slides inside the sliding groove 41 to drive the locking rod 44 to slide inside the connecting groove 43, one end of the locking rod 44 is inserted inside the locking groove 47, the plug block 46 is locked inside the plug-in groove 45, the stability of the clamping block 2 is kept in this way, at this time the sliding block 42 slides to one end of the sliding groove 41, the sliding block 42 pushes the supporting block 3 to slide, the supporting block 3 drives the clamping block 2 to move away from each other, the tire is clamped and fixed from the inside.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
