[0019] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0020] Example

[0021] Please refer to Figure 1-4 As shown, the utility model provides a sports bicycle, a rear seat 15 is arranged on a sports bicycle body 1, and then a sliding frame 2 is slidably connected to the rear seat 15, and then a connecting groove 3 is opened on the surface of the sliding frame 2 to be limitedly slidably connected to the rear seat 15, and the sliding frame 2 is fixedly connected to the rear seat 15 by bolts, so as to facilitate the disassembly and installation of the sliding frame 2 and the placing frame 4 arranged above the sliding frame 2, and at the same time, a placing frame 4 is arranged above the sliding frame 2, and then two shielding cloths 10 are symmetrically arranged on the top of the placing frame 4, and then a movable connecting strip 11 is connected to the sides of the two shielding cloths 10 that are close to each other, and two sliding grooves 14 are symmetrically opened on the left and right sides of the top of the placing frame 4, and both ends of the two movable connecting strips 11 are limitedly slidably connected in the sliding grooves 14, and at the same time, a fixed seat 12 is fixedly connected to the top of the placing frame 4 and located on both sides of the two sliding grooves 14, and finally a spring 13 is connected between the four fixed seats 12 and the movable connecting strip 11;

[0022] When the top of the placement frame 4 is opened, the two movable connecting bars 11 can be used to pull the two side edges of the shielding cloths 10 that are close to each other away from each other, and then the top of the placement frame 4 can be opened, and then the items can be placed in the placement frame 4, or the items in the placement frame 4 can be taken out, and then the two movable connecting bars 11 are released, and the two movable connecting bars 11 are moved closer to each other under the elastic force of the spring 13, thereby driving the two side edges of the shielding cloths 10 to move closer to each other again, so that the top of the placement frame 4 is shielded and protected by the two shielding cloths 10;

[0023] As a further implementation of this embodiment, Figure 1-4 As shown, at the same time, a fixing strip 16 is connected to the side of the shielding cloth 10 that is away from each other and passes through the side wall of the placement frame 4, and then the fixing strip 16 is connected to the surface of the placement frame 4. Through the setting of the two fixing strips 16, one side of the shielding cloth 10 can be limited and fixed. At the same time, a two-way threaded screw 5 is connected to the limited rotation in the placement frame 4, and one end of the two-way threaded screw 5 is movably passed through the side wall of the placement frame 4 and is connected to an adjusting button 9. The two-way threaded screw 5 can be rotated and adjusted by the setting of the adjusting button 9. The outer side of the adjusting button 9 is provided with rough texture. The setting of the rough texture can increase the friction between the hand and the adjusting button 9, which is convenient for rotating the adjusting button 9. Then, two sliders 6 are symmetrically sleeved on the outer side of the two-way threaded screw 5. The top of the two sliders 6 is fixedly connected with a pressure plate 7, and the opposite surfaces of the two pressure plates 7 are connected with rubber plates 8.

[0025] Specific working principle:

[0026] When the top of the placement frame 4 is opened to place items in the placement frame 4, the two movable connecting bars 11 can be used to pull the two side edges of the shielding cloths 10 that are close to each other away, and then the top of the placement frame 4 can be opened, and then the items can be placed in the placement frame 4, and then the two movable connecting bars 11 are released. The two movable connecting bars 11 are close to each other under the elastic force of the spring 13, thereby driving the two side edges of the shielding cloths 10 close to each other again, so that the top of the placement frame 4 is shielded and protected by the two shielding cloths 10, and then the bidirectional threaded screw 5 is rotated and adjusted by the adjusting knob 9, and then the two sliders 6 are driven by the rotating and adjusted bidirectional threaded screw 5 to drive the two pressure plates 7 to approach each other, and then the items set between the two pressure plates 7 are limited and clamped to prevent the items from shaking. In this structure, the top of the placement frame 4 can be shielded and protected by the setting of the two shielding cloths 10, and the two shielding cloths 10 that are quickly opened and closed can facilitate the taking and placing of items in the placement frame 4, thereby improving the practicality of the device.
