Description

Technical Field

[0001] The utility model relates to the technical field of tire changing machines, in particular to a rotating rod type tire changing hook. Background Art

[0002] Tire removal and installation are routine and crucial operations in automotive maintenance and repair. Traditionally, tire changers, as key equipment for this task, have had their structural design and functionality directly impacted on both efficiency and safety. The tire hook, an integral component of the machine, securely holds the tire during the process, ensuring a smooth transition.

[0003] Currently on the market, the connection method between the tire hook and the rotating arm is generally bolt locking and fixing. This method has the advantages of simple structure and reliable connection, but during the installation and disassembly process, tools are needed to tighten and loosen the bolts. The operation is relatively complicated and time-consuming, which is not conducive to quick response and efficient operation.

[0004] Chinese patent CN115284797A discloses a vehicle tire removal device that uses a pneumatic cylinder connected to a tire hook. The cylinder's telescopic movement allows for rapid positioning and locking of the tire hook. Using the pneumatic cylinder requires additional auxiliary equipment such as an air pump or hydraulic pump, which not only increases the overall cost of the device but also limits its use cases, particularly in outdoor environments without a stable power or air source.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0020] like Figure 1-Figure 3 As shown, a rotating rod type tire changing hook includes a connecting plate body 2, which can be connected to the rotating arm 1 of the tire changing machine. The end of the connecting plate body is rotatably connected to the middle part of the hook body 6. Two mounting seats 3 are provided on the top of the connecting plate. A rotating shaft 8 is rotatably connected between the two mounting seats. The rotating shaft is provided with a rotating roller 81, which is convenient for cooperating with the swing lever group to achieve the positioning of the hook body. A swing lever group 5 is rotatably connected to the top of the hook body. A flexible spring 7 is installed between the hook body and the connecting plate body. Under the action of the flexible spring, the swing lever group can be tightly pressed against the rotating roller to ensure the stability and use effect of the tire changing hook.

[0021] In at least one embodiment, the end of the rotating shaft passes through the mounting base and is connected to a hand wheel 4, which rotates to rotate the rotating roller. The design of the hand wheel allows the operator to easily control the rotation of the rotating roller, thereby improving the usability and operability of the device.

[0022] In at least one embodiment, a first fixed shaft 21 is provided on the connecting plate body. The design of the first fixed shaft provides a stable fixing point for the flexible spring, thereby ensuring the stability and reliability of the flexible spring during operation.

[0023] In at least one embodiment, the swing arm group includes a rotating ring 51, which is connected to a screw rod 52, and the end of the screw rod is threadedly connected to a supporting rod 54, and the screw rod is threadedly connected to a fastening nut 53, and the fastening bolt can contact the supporting rod to avoid loosening between the supporting rod and the screw rod.

[0024] In at least one embodiment, Figure 3 As shown, an upper slot 62 for accommodating the insertion of a rotating ring is provided at the top of the hook body, top through holes 64 are provided on both sides of the upper slot, and a central through hole 63 is provided in the middle of the hook body.

[0025] Furthermore, a second fixed shaft 61 is inserted into the two top through holes, and a flexible spring is installed after the end of the second fixed shaft passes through the hook body. Through the second fixed shaft, the flexible spring can be firmly connected to the hook body, further ensuring the stability and use effect of the tire hook.

[0026] Furthermore, the end of the connecting plate is provided with a third fixed shaft 22, which cooperates with the central through hole. Through the cooperation of the third fixed shaft and the central through hole, the connecting plate can be firmly connected to the hook body, ensuring the overall stability and use effect of the tire hook.

[0027] Working method, connect the connecting plate body 2 to the rotating arm 1 of the tire changer. Make sure that the third fixed shaft 22 at the end of the connecting plate body is inserted into the central through hole 63 in the middle of the hook body 6 to achieve a rotating connection. Install the rotating shaft 8 between the two mounting seats 3 at the top of the connecting plate body, and install the rotating roller 81 on the rotating shaft. Rotate and connect the swing arm group 5 to the top of the hook body, specifically by inserting the rotating ring 51 into the upper slot 62 at the top of the hook body, and use the second fixed shaft 61 to pass through the top through hole 64 to fix it. Install a flexible spring 7 between the connecting plate body and the hook body, one end of which can be connected to the first fixed shaft 21, and the other end is connected to the end of the second fixed shaft 61.

[0028] When the tire needs to be changed, the hook body is manually rotated so that the end of the swing arm assembly 5 rests against the rotating roller 81. At this time, the swing arm assembly is affected by the flexible spring and remains in this state during the tire changing process. When the tire is changed, the handwheel 4 is turned to drive the rotating shaft 8 and the rotating roller 81 to rotate. As the rotating roller 81 rotates, the junction point between the swing arm assembly 5 and the rotating roller 81 gradually moves vertically upward. When a certain critical point is reached, the elastic force of the flexible spring 7 is rapidly released, causing the swing arm assembly 5 to disengage from the rotating roller 81, thereby releasing the hook body 6. Regularly check the wear of the flexible spring 7, the rotating shaft 8, and their related components, and replace or repair them as necessary.

[0029] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
