[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-4The illustration shows a marathon timing device that is easy to install. It includes a protective housing 3, which primarily protects the core components of the internal timing device from damage caused by external factors such as collisions, friction, and rain during the race. The protective housing 3 contains a locking assembly for quick installation and removal of the timer 11 from the protective housing 3. The locking assembly includes a connecting shaft 17 rotatably connected to the inside of the protective housing 3. The connecting shaft 17 provides a rotational support point for a rotating block 19, allowing the rotating block 19 to rotate stably around it. The rotating block 19 is fixedly connected to the side wall of the connecting shaft 17, and can rotate under the support of the connecting shaft 17, thereby driving the movement of components such as the locking block 22 to achieve the locking and unlocking actions. A first spring 18 is fixedly connected to the bottom of the rotating block 19. The other end of the first spring 18 is fixedly connected to the inner bottom wall of the protective shell 3. The first spring 18 provides elastic force. When the rotating block 19 is rotated under force, the first spring 18 stores elastic potential energy. When the external force is removed, the elastic potential energy is used to reset the rotating block 19. A locking block 22 is fixedly connected to the top of the rotating block 19. The locking block 22 is used to cooperate with the corresponding slot 2 on the timer 11 to firmly lock the timer 11 into the protective shell 3, ensuring the stability of the timing device during use. A fixing plate 21 is fixedly connected to the top of the rotating block 19. The fixing plate 21 connects and supports the push block 20, ensuring that the push block 20 can move with the rotation of the rotating block 19. A push block 20 is fixedly connected to the side wall of the fixing plate 21. The push block 20 penetrates the protective shell 3 and slides inside the side wall of the protective shell 3. By pushing the push block 20, the operator can drive the fixing plate 21, rotating block 19 and other components to move, thereby releasing the locking block 22 to facilitate the removal of the timer 11. Alternatively, the operation can be reversed by pushing the push block 20 to lock the locking block 22 into place, thus completing the installation.

[0025] Example 2: Reference Figure 1-4Based on the same concept as Embodiment 1 above, this embodiment further proposes that the protective shell 3 provides physical protection for the entire device, preventing the timer 11 from being damaged by collisions, scratches, or moisture. The timer 11, the core timing element, is installed inside, accurately recording the contestant's time and ensuring the accuracy and fairness of the competition results. A display screen 4 is installed on the side wall of the timer 11, which can display key information such as time and contestant's segment scores in real time, facilitating quick viewing by staff and contestants. A connecting plate 12 is fixedly connected to the side wall of the timer 11, acting as a bridge to connect the timer 11 to the locking structure inside the protective shell 3. The connecting plate 12 has a locking hole 13 inside that matches the locking block 22. When the locking block 22 is engaged in the locking hole 13, it can firmly fix the timer 11 inside the protective shell 3, ensuring that it will not shake or fall off during use. A second spring 16 is fixedly connected to the inner bottom wall of the protective shell 3, providing upward elastic force. The other end is fixedly connected to a connecting block 15, which moves upward under the elastic force of a second spring 16. A slider 14 is fixedly connected to the side wall of the connecting block 15, which slides inside the protective shell 3, guiding and limiting the connecting block 15 to ensure that it can only move in a specific direction. A wristband 1 is fixedly connected to the bottom of the protective shell 3, which allows the athlete to wear the timing device and carry it conveniently during the competition. A moving block 5 is fixedly connected to one end of the wristband 1, which is used to install and fix components such as the pressing block 6. A pair of pressing blocks 6 are slidably connected inside the moving block 5, and the pair of pressing blocks 6 can slide towards or away from each other within the moving block 5. A third spring 8 is provided between the pair of pressing blocks 6, which provides elastic force to make the pressing blocks 6 tend to move away from each other. A fixing block 9 is fixedly connected inside the moving block 5, which supports and positions the third spring 8. A spring hole 10 adapted to the third spring 8 is opened inside the fixing block 9, and the third spring 8 is installed in the spring hole 10 to ensure its stable position. Each compression block 6 has a fixed limiting block 7 at its bottom, which can move with the compression block 6. The side wall of the wristband 1 has multiple slots 2 that fit the limiting block 7. When the limiting block 7 is inserted into different slots 2, the wearing size of the wristband 1 can be adjusted to meet the needs of different athletes.

[0026] The working principle of this device is as follows: When using this device, first insert the timer 11 into the protective shell 3. The connecting plate 12 presses the connecting block 15, causing the second spring 16 to deform and the locking block 22 to be inserted into the locking hole 13, so that the timer 11 will not fall off. Then, wrap the wristband 1 around the wrist and insert one end of the wristband 1 into the insertion port at the bottom of the moving block 5. According to the thickness of the individual's wrist, press the squeezing block 6 to deform the third spring 8 and change the insertion length of the wristband 1. Release the squeezing block 6, and the limiting block 7 will be inserted into the locking slot 2 to complete the fixation. When it is necessary to remove the timer 11, press down on the push block 20 to deflect the rotating block 19 and squeeze the first spring 18, thereby causing the locking block 22 to disengage from the locking hole 13.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
