Description

Technical Field

[0001] This utility model relates to the field of stopwatch technology, specifically a stopwatch response speed testing device. Background Technology

[0002] The stopwatch response speed testing device is mainly used to test the speed performance of a stopwatch in response to sudden events, ensuring that it can meet the time measurement accuracy requirements in specific scenarios.

[0003] In the existing stopwatch response speed testing device, when the stopwatch is dropped while being held by a person, the stability of the internal components of the stopwatch is poor, the speed data becomes disordered, and the stopwatch components are damaged. At the same time, the test display screen of the stopwatch is not protected, and the mirror is easily scratched by friction with the outside world, which reduces the protection of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a stopwatch response speed testing device, which has the advantages of increased testing stability and stopwatch protection, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a stopwatch response speed testing device, comprising a stopwatch body, a limit rod slidably sleeved on the outer wall of the stopwatch body, a groove formed on the outer wall of the stopwatch body, a slider slidably sleeved on the outer wall of the groove, a pressure plate fixedly installed on the outer wall of the limit rod, a first spring movably sleeved on the outer wall of the limit rod, a guide groove formed on the inner wall of the stopwatch body, a protective shell fixedly installed on the outer wall of the slider, a base block fixedly installed on the inner wall of the stopwatch body, a round rod fixedly installed on the top of the base block, a square block fixedly connected to the top of the round rod, a magnet installed on the inner wall of the square block, a square tube slidably connected to the inner wall of the guide groove, a second spring fixedly installed on the inner wall of the square tube, and a locking block fixedly connected to one end of the second spring.

[0006] As a preferred technical solution of this utility model: the guide groove is provided with a slot, and the inner wall of the square tube is engaged with the outer wall of the block.

[0007] As a preferred technical solution of this utility model: the number of sliders is two, and the two sliders are symmetrically arranged with the protective shell as the center.

[0008] As a preferred technical solution of this utility model: the outer wall of one end of the limiting rod is in contact with the outer wall of the locking block, and one end of the first spring is fixed to the pressure plate.

[0009] As a preferred technical solution of this utility model: the number of magnets is two, and the magnets are respectively snapped into the inner walls of the square block and the round rod, with the N poles of the two magnets being set in opposite directions.

[0010] As a preferred technical solution of this utility model: several round rods are evenly distributed at the four bottom corners of the block, and the bottom of several round rods are slidably connected to the inner wall of the block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This stopwatch response speed testing device utilizes the fact that the corresponding surfaces of two magnets are of the same polarity. The repulsion between like poles between the two magnets creates a shock-absorbing effect, preventing damage to the inner components when the stopwatch falls and collides with the outside world. Several round rods evenly distributed at the four corners of the bottom of the block can limit the position of the block and the bottom block, preventing them from shifting during the shock absorption process and increasing the stability of the device.

[0012] 2. This stopwatch response speed testing device uses external force to compress the protective shell and square cylinder against the inner wall of the guide groove, causing the second spring to slide. This, in turn, causes the second spring to slide the locking block into the slot. The spring force pushes the locking block into the slot, thus securing the protective shell to the stopwatch body. Applying external force to the limiting rod causes the limiting rod to move a pressure plate against the first spring, pushing the locking block out of the slot and allowing the protective shell to slide, exposing the outer wall of the stopwatch body for testing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see Figures 1-5 A stopwatch response speed testing device includes a stopwatch body 1, a limit rod 4 slidably sleeved on the outer wall of the stopwatch body 1, a groove 9 opened on the outer wall of the stopwatch body 1, a slider 3 slidably sleeved on the outer wall of the groove 9, a pressure plate 8 fixedly installed on the outer wall of the limit rod 4, a first spring 7 movably sleeved on the outer wall of the limit rod 4, a guide groove 11 opened on the inner wall of the stopwatch body 1, a protective shell 2 fixedly installed on the outer wall of the slider 3, a base block 16 fixedly installed on the inner wall of the stopwatch body 1, a round rod 13 fixedly installed on the top of the base block 16, a square block 12 fixedly connected to the top of the round rod 13, a magnet 14 installed on the inner wall of the square block 12, a square tube 5 slidably connected to the inner wall of the guide groove 11, a second spring 10 fixedly installed on the inner wall of the square tube 5, and a locking block 6 fixedly connected to one end of the second spring 10.

[0017] In the above structure, by installing the protective shell 2, the outer wall of the stopwatch body 1 is protected, thus preventing damage to the display screen and extending its service life.

[0018] In a preferred embodiment: the guide groove 11 has a slot 15, and the inner wall of the square tube 5 is engaged with the outer wall of the block 6.

[0019] In the above structure, the protective shell 2 drives the square tube 5 to compress the second spring 10 against the inner wall of the guide groove 11 by external force, so that the second spring 10 drives the locking block 6 to slide into the locking groove 15. The elastic force of the second spring 10 pushes the locking block 6 to engage with the locking groove 15, thereby achieving a stable connection between the protective shell 2 and the stopwatch body 1.

[0020] In a preferred embodiment, there are two sliders 3, and the two sliders 3 are symmetrically arranged with the protective shell 2 as the center.

[0021] In the above structure, the protective shell 2 drives the two sliders 3 to slide against the guide groove 11, so that the guide groove 11 limits the movement trajectory of the protective shell 2 and prevents derailment.

[0022] In a preferred embodiment: one end of the limiting rod 4 is in contact with the outer wall of the locking block 6, and one end of the first spring 7 is fixed to the pressure plate 8.

[0023] In the above structure, by applying external force to the limiting rod 4, the limiting rod 4 drives the pressure plate 8 to abut against the first spring 7, so that the limiting rod 4 pushes the locking block 6 to disengage from the locking groove 15, causing the protective shell 2 to slide and expose the outer wall of the stopwatch body 1 for personnel to test.

[0024] In a preferred embodiment, there are two magnets 14, which are respectively snapped into the inner walls of the block 12 and the round rod 13, and the N poles of the two magnets 14 are arranged opposite each other.

[0025] In the above structure, the corresponding surfaces of the two magnets 14 are of the same polarity. The repulsion between the like poles of the two magnets 14 reduces the impact of vibration, thus increasing the stability of the inner wall components and preventing damage caused by vibration when the stopwatch body 1 falls and collides with the outside world.

[0026] In a preferred embodiment: a plurality of round rods 13 are evenly distributed at the four bottom corners of the block 12, and the bottom of the plurality of round rods 13 is slidably connected to the inner wall of the bottom block 16.

[0027] In the above structure, several round rods 13 are evenly distributed at the four bottom corners of the block 12, which can limit the position of the block 12 and the bottom block 16, preventing the block 12 and the bottom block 16 from shifting position during the shock absorption process, thus increasing the stability of the device.

[0028] Working principle: External force compresses the protective shell 2 and the square tube 5, causing the second spring 10 to slide against the inner wall of the guide groove 11. This causes the second spring 10 to slide the locking block 6 into the locking groove 15. The elastic force of the second spring 10 pushes the locking block 6 into the locking groove 15, thus achieving a stable connection between the protective shell 2 and the stopwatch body 1. External force is applied to the limiting rod 4, which in turn causes the pressure plate 8 to abut against the first spring 7. This pushes the limiting rod 4 to disengage the locking block 6 from the locking groove 15, allowing the protective shell 2 to slide and exposing the outer wall of the stopwatch body 1 for human use. In the test, the two magnets 14, whose corresponding faces are of the same polarity, repel each other, thus achieving shock absorption. This increases the stability of the inner wall components and prevents damage from vibration when the stopwatch body 1 falls and collides with the outside world. Several round rods 13 are evenly distributed at the four corners of the bottom of the block 12, which can limit the position of the block 12 and the bottom block 16, preventing them from shifting during shock absorption and increasing the stability of the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
