Now, people mainly use bicycles for physical exercise during cycling. Having a comfortable cycling experience during the ride is very important. As a rotating part in contact with the ground, the wheels can rotate smoothly, which can bring a good experience to the cyclists.

[0003] The prior art document with the publication number of CN212620531U provides a true roundness tester for bicycle rims. The device includes a bottom plate, a testing mechanism and a placement mechanism. The testing mechanism and the placement mechanism are respectively fixedly installed at the top of the bottom plate. The testing mechanism includes two screws, a lower testing plate, two first connection blocks and an upper testing plate. This device can detect the rim through two micrometers arranged up and down, so as to know the true roundness of the rim, thereby improving the practicability of the tester.

[0004] However, in the prior art described in the above device, when detecting a bicycle rim, only a single detection of the true roundness or the runout of the end face of the rim can be carried out, making the detection incomplete and inaccurate. In view of this, we propose a detection device for detecting moving parts of a bicycle. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, when detecting a bicycle rim, only a single detection of the true roundness or the runout of the end face of the rim can be carried out, making the detection incomplete and inaccurate. The utility model proposes a detection device for detecting moving parts of a bicycle.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A detection device for detecting moving parts of a bicycle described in the utility model includes a detection table. A first shaft cylinder is rotatably installed on the detection table. A swing rod is rotatably connected to the side of the detection table. A first telescopic rod is arranged at the upper end of the swing rod. A second shaft cylinder is arranged at the telescopic end of the first telescopic rod. On the other side of the detection table, there is an installation plate. A stretchable and adjustable support frame is arranged at the lower end of the installation plate. A slide rail is installed at the upper end of the installation plate. A slider is slidably arranged in the slide rail. A connecting frame is rotatably arranged at the upper end of the slider. A second telescopic rod is installed at the other end of the connecting frame. A dial gauge measuring tool is installed at the telescopic end of the second telescopic rod.

[0007] Preferably, a first driving mechanism is connected to the lower end of the swing rod, and the telescopic direction of the first telescopic rod is up and down telescoping.

[0008] Preferably, grooves for inserting the bicycle wheel axle are provided inside both the first shaft cylinder and the second shaft cylinder, and the grooves are trapezoidal structures that become narrower from the opening to the bottom.

[0009] Preferably, the first lead screw is inserted through the support frame, and a threaded engagement structure is formed between the first lead screw and the support frame. A first servo motor is installed at one end of the first lead screw.

[0010] Preferably, a second lead screw is rotatably arranged inside the slide rail, and a threaded engagement structure is formed between the second lead screw and the slider. A second servo motor is connected to one end of the second lead screw.

[0011] Preferably, a third telescopic rod is connected to the rotating part between the slider and the connecting frame. The telescopic end of the third telescopic rod is connected to the rotating shaft of the connecting frame, and the other end of the third telescopic rod is connected to one side of the slide rail.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. Through the rotational adjustment between the connecting frame and the slider, the present utility model can drive the dial indicator measuring tool to rotate and adjust, enabling the dial indicator measuring tool to be in a vertical state and a horizontal state respectively. In this device, the bicycle wheel rim is horizontally placed on the inspection table. Therefore, when the dial indicator measuring tool is in the horizontal state, it can be abutted against the side of the bicycle wheel rim to detect the circularity of the wheel rim.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 As shown, a detection device for detecting bicycle moving parts includes an inspection table 1, a first shaft cylinder 4 is rotatably installed on the inspection table 1, a swing rod 2 is rotatably connected to the side of the inspection table 1, a first telescopic rod 3 is arranged at the upper end of the swing rod 2, and a second shaft cylinder 5 is arranged at the telescopic end of the first telescopic rod 3; a mounting plate 6 is arranged on the other side of the inspection table 1, a support frame 7 that can be extended and adjusted is arranged at the lower end of the mounting plate 6, a slide rail 8 is installed at the upper end of the mounting plate 6, a slide block 9 is slidably arranged in the slide rail 8, a connecting frame 10 is rotatably arranged at the upper end of the slide block 9, a second telescopic rod 11 is installed at the other end of the connecting frame 10, and a dial indicator measuring tool 12 is installed at the telescopic end of the second telescopic rod 11;

[0024] When detecting a bicycle rim, first place the rim on the detection table 1. Then, through the rotational adjustment of the connecting frame 10 and the slider 9, the dial gauge 12 can be driven to be in a horizontal state or a vertical state, so as to detect the roundness of the rim and the runout of the end face. And when the state of the dial gauge 12 is adjusted, through the expansion adjustment of the support frame 7, the sliding adjustment of the slider 9 on the slide rail 8, and the telescopic adjustment of the second telescopic rod 11, the dial gauge 12 can accurately press against the rim to detect the rim.

[0025] By using the rotational adjustment between the connecting frame 10 and the slider 9, the dial gauge 12 can be driven to rotate and adjust, so that the dial gauge 12 can be in a vertical state and a horizontal state respectively. In this device, the bicycle rim is horizontally placed on the detection table 1. Therefore, when the dial gauge 12 is in a horizontal state, it can press against the side of the bicycle rim to detect the roundness of the rim. When the dial gauge 12 is in a vertical state, it can press against the upper end face of the bicycle rim to detect the total runout of the rim, thus making the state detection of the rim more accurate.

[0026] Please refer to Figure 2 As shown, a first driving mechanism 21 is connected to the lower end of the swing rod 2, and the telescopic direction of the first telescopic rod 3 is up and down telescoping.

[0027] When the rim is taken and placed on the detection table 1, the swing rod 2 can be driven by the first driving mechanism 21 to deflect to one side, and then the rim can be taken away. Or the rim can be placed on the detection table 1, and then the swing rod 2 can be driven by the first driving mechanism 21 to deflect towards the detection table 1 side to align the first shaft cylinder 4 with the second shaft cylinder 5. Then, through the extension of the first telescopic rod 3, the second shaft cylinder 5 is sleeved on the upper end of the axle of the rim.

[0028] Grooves for inserting the bicycle wheel axle are provided on the inner sides of both the first shaft cylinder 4 and the second shaft cylinder 5, and the grooves are trapezoidal structures that become narrower from the opening to the bottom.

[0029] When the rim is placed on the detection table 1 for operation, first insert one end of the rim into the groove of the first shaft cylinder 4. Then, when the swing rod 2 drives the second shaft cylinder 5 to swing and align, use the extension of the first telescopic rod 3 to sleeve the second shaft cylinder 5 on the upper end of the axle of the rim. This can make the rim rotate easily on the detection table 1 for convenient detection. The grooves of the first shaft cylinder 4 and the second shaft cylinder 5 are trapezoidal structures, which can conveniently meet the usage requirements of different diameters of rims on different rims. Thicker axles are inserted shallower into the groove, and thinner axles are inserted deeper into the groove. However, axles of any thickness can press against the inner wall of the groove, which is convenient for using the inner wall of the groove to support the axle and facilitate the rotation of the rim.

[0030] The first lead screw 71 is inserted through the support frame 7, and there is a threaded engagement structure between the first lead screw 71 and the support frame 7. One end of the first lead screw 71 is equipped with a first servo motor 72;

[0031] The first servo motor 72 drives the first lead screw 71 to rotate. Since the first lead screw 71 and the support frame 7 are connected by a threaded joint, it can drive the support frame 7 to adjust upward extension or downward retraction, facilitating the requirement that the dial indicator measuring tool 12 can be abutted against the wheel rim for measurement whether in a horizontal state or a vertical state.

[0032] A second lead screw 81 is rotatably arranged inside the slide rail 8, and there is a threaded engagement structure between the second lead screw 81 and the slider 9. One end of the second lead screw 81 is connected to a second servo motor 82;

[0033] The second servo motor 82 drives the second lead screw 81 to rotate. And since there is a threaded engagement between the second lead screw 81 and the slider 9, it can drive the slider 9 to move on the slide rail 8, thereby driving the dial indicator measuring tool 12 to move away from or close to the wheel rim to meet the detection needs of different wheel rim diameters.

[0034] A third telescopic rod 101 is connected at the rotating part between the slider 9 and the connecting frame 10. The telescopic end of the third telescopic rod 101 is connected to the rotating shaft of the connecting frame 10, and the other end of the third telescopic rod 101 is connected to one side of the slide rail 8;

[0035] The telescopic movement of the third telescopic rod 101 can drive the rotation between the connecting frame 10 and the slider 9. Through the rotation of the connecting frame 10, it can drive the dial indicator measuring tool 12 to rotate, making it in a vertical state or a horizontal state to detect the wheel rim;

[0036] In addition, the dial indicator measuring tool 12 is installed on the second telescopic rod 11. Through the telescopic movement of the second telescopic rod 11, it can drive the dial indicator measuring tool 12 to make a fine adjustment in position, facilitating better meeting the detection of the wheel rim.

[0037] Working principle: When detecting the bicycle wheel rim, first place the wheel rim on the detection table 1. Then, through the rotation adjustment of the connecting frame 10 and the slider 9, it can drive the dial indicator measuring tool 12 to be in a horizontal state or a vertical state, thereby detecting the roundness and runout of the end face of the wheel rim. And when the state of the dial indicator measuring tool 12 is adjusted, through the expansion adjustment of the support frame 7, the sliding adjustment of the slider 9 on the slide rail 8, and the telescopic adjustment of the second telescopic rod 11, the dial indicator measuring tool 12 can accurately abut against the wheel rim to detect the wheel rim.
