[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, a protective lampshade for a gymnasium comprises an upper shell 1 and a lower shell 2, the cross sections of the upper shell 1 and the lower shell 2 are both arc-shaped, the LED lamp tube is fixed in the upper shell 1, and the lower shell 2 is fixed at the lower end of the upper shell 1, and cooperates with the upper shell 1 to surround the LED lamp tube, thereby preventing a volleyball from hitting the LED lamp tube inside the upper shell 1 and causing damage; and the lower shell 2 is hollowed out to ensure that the light of the LED lamp tube can pass through the lower shell 2 to irradiate the gymnasium;

[0026] In some embodiments, the lower housing 2 may be made of a transparent material, such as transparent tempered glass, transparent acrylic plate, etc., to increase the brightness of the LED lamp;

[0027] In this embodiment, if Figures 2 to 4 As shown, a connecting seat 11 is provided on one side of the lower end of the upper shell 1, and a rotating shaft 22 is fixed on one side of the upper end of the lower shell 2, and the rotating shaft 22 is rotatably connected to the connecting seat 11, thereby realizing the hinge connection between the upper shell 1 and the lower shell 2; a first fixing plate 12 is fixed on the side of the lower end of the upper shell 1 away from the connecting seat 11, and a yield groove 13 is opened on the first fixing plate 12, and a second fixing plate 21 is fixed on the side of the upper end of the lower shell 2 away from the rotating shaft 22, and a screw is threadedly connected to the upper end of the second fixing plate 21. During the flipping of the lower shell 2 around the rotating shaft 22, the screw can reach the yield groove 13, and by tightening the screw, the screw head can be tightly attached to the upper end of the first fixing plate 12, thereby realizing the fixed connection between the upper shell 1 and the lower shell 2, and the lower shell 2 can be disassembled and opened by removing the bolts, so as to facilitate the disassembly and replacement of the LED lamp tube inside the upper shell 1;

[0028] In addition, if Figure 2 As shown, a torsion spring 3 is sleeved on the rotating shaft 22, and the two ends of the torsion spring 3 are fixedly connected to the lower shell 2 and the connecting seat 11 respectively. Under the torsion force of the torsion spring 3, the lower shell 2 has a tendency to flip away from the upper shell 1, thereby being able to apply pre-pressure between the screw and the first fixed plate 12.

[0029] Of course, the fixing method between the lower shell 2 and the upper shell 1 includes but is not limited to the hinged fixation in the present embodiment. In some embodiments, bolts can be set between the upper shell 1 and the lower shell 2 to achieve a detachable fixed connection between the two. When the LED lamp needs to be replaced later, it is only necessary to remove the bolts; however, compared to the hinged fixation in the present embodiment, in the present embodiment, only one bolt needs to be loosened, and under the action of the torsion spring 3, the lower shell 2 can be opened, thereby improving the convenience of replacing the LED lamp.

[0030] A connecting rod 4 is fixed to the upper end of the upper shell 1, and a fixing rod 5 is arranged at the upper end of the connecting rod 4. The connecting rod 4 and the fixing rod 5 are slidably connected in the vertical direction, and a spring 6 is installed between the connecting rod 4 and the fixing rod 5 to realize elastic connection. In this embodiment, Figure 1 As shown, a bracket 7 is fixed on the ground, and a fixing rod 5 is fixed to the upper end of the bracket 7. When the volleyball collides with the lower shell 2, the spring 6 will contract to buffer the impact force on the upper shell 1, the lower shell 2 and the LED lamp;

[0031] Of course, the fixing position of the fixing rod 5 includes but is not limited to the bracket 7 in this embodiment. In some embodiments, the fixing rod 5 can also be fixed on the top of the gymnasium.

[0032] like Figure 5 and Figure 6 As shown, a limit block 41 is provided on the connecting rod 4, and a limit groove 51 is opened on one side of the fixing rod 5. The limit block 41 is located in the limit groove 51. Under the elastic force of the spring 6, the limit block 41 is tightly attached to the lower end of the limit groove 51 to prevent the connecting rod 4 and the fixing rod 5 from detaching from each other.

[0033] It is worth mentioning that, in this embodiment, a connecting plate 42 is provided at the lower end of the connecting rod 4, and the connecting plate 42 is fixed to the upper housing 1 by bolt connection, so as to facilitate later disassembly;

[0034] Of course, the fixing method between the connecting plate 42 and the upper shell 1 includes but is not limited to the bolt connection in this embodiment. In some embodiments, it can also be fixed by welding. However, it is obvious that although welding is more stable, it is not easy to disassemble.

[0035] Working principle:

[0036] By fixing the lower shell 2 at the lower end of the upper shell 1, the LED lamp tube is fixed in the upper shell 1, and the lower shell 2 is hollowed out to achieve anti-collision for the LED lamp tube, so as to prevent it from being directly damaged by impact, and by fixing the connecting rod 4 at the upper end of the upper shell 1, a spring 6 is arranged between the connecting rod 4 and the fixing rod 5 to achieve elastic connection. When the lower shell 2 receives the impact 2, the spring 6 will shrink to buffer the impact force on the upper shell 1, the lower shell 2 and the LED lamp tube, thereby reducing the impact force received by the LED lamp tube and playing a protective role. By setting one end of the lower shell 2 to be hinged with the upper shell 1, and installing a bolt at the other end, by tightening the bolt, the head of the screw can be tightly attached to the upper end of the first fixing plate 12, thereby achieving a fixed connection between the upper shell 1 and the lower shell 2, which is convenient for the later disassembly and replacement of the LED lamp tube.
