Description

Technical Field

[0001] The utility model relates to the technical field of tire changing machines, in particular to a tire changing machine lever positioning component. Background Art

[0002] In the current tire repair equipment landscape, vertical tire changers are highly efficient and versatile, widely used in various automotive repair and service scenarios. To accommodate tires of varying sizes and specifications, these machines are typically equipped with multiple adjustable levers to ensure optimal adaptability and operational flexibility during the tire changing process.

[0003] However, in practical applications, the stability of the rotating rods' positioning has become a pressing technical issue. Specifically, during tire changing operations, the rotating rods must maintain precise positioning to prevent swinging that could affect tire changing and efficiency. Furthermore, after a set of rotating rods is used, they must be rotated to the side to free up space for other tire changing operations.

[0004] Currently, the positioning of the rotating rod usually relies on traditional fixing methods such as bolt locking. Although this method can achieve a certain degree of positioning effect, it lacks a fast and effective locking mechanism to maintain its stable position after the rotating rod is rotated to one side. As a result, in actual operation, the rotating rod that has been rotated to one side is often accidentally rotated back due to external factors (such as vibration, accidental touch, etc.), thereby interfering with the normal tire changing work and even posing a safety hazard to the operator.

DETAILED DESCRIPTION

[0022] 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:

[0023] like Figure 1-Figure 4 As shown, a tire changer lever positioning component includes a rectangular tube body 1, to which a rotating rod group 2 is rotatably connected, and bolt positioning components 5 and torsion spring positioning components 3 are respectively provided on both sides of the rotating rod group. The arrangement of the bolt positioning components and the torsion spring positioning components ensures that the rotating rod group can be stably fixed in a specific position, thereby improving the safety of use. An elastic locking component 4 is provided on the rectangular tube body, and when the rotating rod group rotates to abut against the rectangular tube body, the elastic locking component can limit the rotating rod group from rotating around the rectangular tube body. The design of the elastic locking component enables the rotating rod group to be firmly locked on the rectangular tube body when it is not needed to prevent accidental rotation.

[0024] In at least one embodiment, the rotating rod group includes a rotating sleeve 21, which is connected to an outer sleeve 22, and an extension rod 23 is installed in the outer sleeve. In conjunction with it, a mounting seat 11 is provided on the rectangular tube body, and a rotating shaft 12 is provided between the two mounting seats. The rotating sleeve is rotatably connected to the rotating shaft, and the outer sleeve can rotate around the rotating shaft.

[0025] In at least one embodiment, the bolt positioning member includes a threaded sleeve 51, such as Figure 3 The outer sleeve is welded with a threaded sleeve on the left side, and the threaded sleeve is connected with an adjusting bolt 52. The threaded connection design allows the adjusting bolt to be firmly fixed in the threaded sleeve and is convenient for adjusting the position. Figure 1At the angle shown, the end of the adjusting bolt rests against the rectangular tube.

[0026] In at least one embodiment, the torsion spring positioning member 3 includes two fixing plates 31, a limiting rod, a positioning bolt 32, a positioning nut 38, and a torsion spring 37. The fixing plate is fixedly connected to the outer sleeve. The limiting rod includes a limiting mounting ring 33, the limiting mounting ring is connected to a screw 34, the end of the screw is fixedly connected to a connecting rod 35, and a locking nut 36 is threadedly connected to the screw. The positioning bolt passes through the fixing plate, the limiting mounting ring, the fixing ring, and the torsion spring from bottom to top, and is tightened and fixed by the positioning nut. The torsion spring is sleeved on the positioning bolt, one end of the torsion spring is fixedly connected to the outer sleeve, and the other end is clamped between the locking nut and the connecting rod. The provision of the torsion spring provides continuous torsional force for the connecting rod, allowing it to stably rest against the rectangular tube body.

[0027] Furthermore, the torsion spring can cause the connecting rod to rotate in a direction close to the outer sleeve. This feature ensures that the connecting rod can automatically return to its initial position when no external force is applied, thereby improving the convenience of use.

[0028] Furthermore, the fixing plate is provided with a through hole for accommodating the positioning bolt to pass through.

[0029] In at least one embodiment, the elastic locking member includes a mounting bolt 42, which is threadedly connected to the rectangular tube. The mounting bolt is provided with an elastic wire 41, which cooperates with the end of the positioning bolt 32. This cooperation allows the positioning bolt to be securely locked by the elastic wire in a specific position, preventing accidental rotation.

[0030] Furthermore, the elastic steel wire is formed with an elastic arc-shaped slot 411 for accommodating the fixing of the positioning bolt. The design of the elastic arc-shaped slot allows the positioning bolt to be firmly inserted therein, thereby improving the stability of the locking.

[0031] Furthermore, the end of the elastic wire is provided with a guide portion 412 for facilitating the end of the positioning bolt to enter the elastic arc-shaped slot. The provision of the guide portion makes it smoother for the positioning bolt to be inserted into the elastic arc-shaped slot, thereby improving the convenience of operation.

[0032] Working mode, setting Figure 1 The state shown is horizontal. Figure 3 The state shown is the vertical state.

[0033] Horizontal fixation: When the rotating rod assembly is rotated to the horizontal position, the adjusting bolt of the bolt positioning member is ensured to abut against the rectangular tube. At the same time, the connecting rod of the torsion spring positioning member on the other side of the outer sleeve is also abutted against the rectangular tube under the action of the torsion spring, thus fixing both sides of the rotating rod assembly.

[0034] Vertical Position Securing: After use, manually rotate the connecting rod to elastically deform the torsion spring. Pull the lever assembly to a vertical position. The torsion spring forces the connecting rod to engage the rectangular tube. Simultaneously, the end of the positioning bolt follows the guide of the elastic wire and enters the elastic arc-shaped slot, securing the lever assembly in a vertical position.

[0035] 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.
