[0003] The existing dust detection instrument is usually exposed outside in order not to affect the display effect when using, which leads to the display screen being very easy to be damaged by external collision, and a large amount of dust is also very easy to enter the inside of the display screen, thereby causing the display screen to be damaged, so the dust detection instrument does not have the function of protecting the display screen. UTILITY MODEL CONTENT

[0004] The utility model discloses a dust detection instrument with screen protection structure to solve the problem that the dust detection instrument does not have the function of protecting the display screen.

[0005] To achieve the above object, the utility model provides the following technical scheme: a dust detection instrument with screen protection structure, comprising: a vertical rod and a wind direction and speed detector, the vertical rod is installed on one side with a distribution box, the top of the distribution box is provided with a display screen, the both sides of the vertical rod are installed with lower support frame, the top of the lower support frame is installed with dust sampler, the top of the dust sampler is provided with upper support frame, and the wind direction and speed detector is installed at the top of the upper support frame.

[0006] One side of the display screen is provided with a protection plate, and the both ends of the protection plate are installed with first telescopic blocks through grooves.

[0007] Preferably, the first telescopic block is connected with an end plate at one end away from the protection plate, and the end plate is installed with a second telescopic block on the same side away from the first telescopic block.

[0008] Preferably, the second telescopic block is sleeved with a connecting block at one end, and the bottom of the second telescopic block is connected with a top rod penetrating through the connecting block, and the top rod is connected with a sliding block at one end.

[0012] Preferably, the end of the connecting rod away from the screw sleeve is connected to a movable frame via a rotating shaft, and a tarpaulin is connected between the groove of the movable frame and the fixed frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the dust detector with screen protection structure is impacted, the protective plate moves to one side of the display screen, causing the first telescopic block to drive the end plate to move. When the end plate moves, it pushes the connecting block to move through the second telescopic block. The connecting block causes the movable spring to be in a stretched state, thereby protecting the display screen. Similarly, when the end plate is impacted and moves towards the display screen, the second telescopic block and the top rod will compress the telescopic spring. Through the deformation of the telescopic spring, both ends of the display screen can be protected, and the dustproof effect of the display screen is also improved, preventing dust from entering the display screen and causing damage. This is the characteristic of the dust detector with screen protection structure.

[0021] 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.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a dust detector with a screen protection structure, including: a pole 1 and a wind direction and speed detector 23, a power distribution box 2 is installed on one side of the pole 1, a display screen 3 is installed on the top of the power distribution box 2, a lower support frame 4 is installed on both sides of the pole 1, a dust sampler 5 is installed on the top of the lower support frame 4, an upper support frame 6 is installed on the top of the dust sampler 5, and the wind direction and speed detector 23 is installed on the top of the upper support frame 6;

[0023] A protective plate 7 is provided on one side of the display screen 3. Both ends of the protective plate 7 are fitted with first telescopic blocks 8 through grooves. The end of the first telescopic block 8 away from the protective plate 7 is connected to an end plate 9. A second telescopic block 10 is installed on the same side of the end plate 9 away from the first telescopic block 8. A connecting block 11 is sleeved on one end of the second telescopic block 10. A top rod 12 that passes through the connecting block 11 is connected to the bottom of the second telescopic block 10. A slider 13 is connected to one end of the top rod 12. A movable spring 14 is installed between the top rod 12 and the connecting block 11. A telescopic spring 15 is installed between the bottom of the top rod 12 and the groove of the connecting block 11. The slider 13 forms a sliding structure with the display screen 3 through a sliding groove on one side of the display screen 3.

[0024] In practical implementation, when the two ends of the display screen 3 are impacted, the end plate 9 will move towards the display screen 3. The movement of the end plate 9 will drive the first telescopic block 8 to move into the groove of the protective plate 7, and drive the second telescopic block 10 to move into the interior of the connecting block 11. Since one end of the second telescopic block 10 is connected to a top rod 12 that passes through the connecting block 11, when the second telescopic block 10 moves, it will push the top rod 12 to move, so that the top rod 12 slides along the slide groove on one side of the display screen 3 through the slider 13 on one side. In addition, a telescopic spring 15 is installed in the groove between the top rod 12 and the connecting block 11. When the top rod 12 moves, it will squeeze the telescopic spring 15, so that the telescopic spring 15 is in a compressed state. The telescopic spring 15 can buffer the second telescopic block 10 and the end plate 9, and prevent the two ends of the display screen 3 from being violently impacted.

[0025] When the front of the display screen 3 is impacted, the protective plate 7 will move the end plate 9 to one side via the first telescopic block 8. The movement of the end plate 9 will then move the bottom connecting block 11 via the second telescopic block 10. A movable spring 14 is connected between the connecting block 11 and the display screen 3, and the movable spring 14 is sleeved on the outside of the top rod 12. Since one end of the top rod 12 is connected to the slide groove on one side of the display screen 3 via the slider 13, the connecting block 11 will not move the top rod 12 when it moves. Instead, the top rod 12 will slide along the groove of the connecting block 11. The movement of the connecting block 11 will cause the movable spring 14 to be in a stretched state. Through the deformation of the movable spring 14, the protective plate 7 can be cushioned to prevent the front of the display screen 3 from being impacted.

[0026] See Figure 2 and Figure 4 It is known that during use, the end plate 9 or the protective plate 7 of the display screen 3 can be moved according to the direction of the collision, thereby providing good protection for the display screen 3. Furthermore, the protective plate 7 is made of transparent acrylic sheet, so it will not affect the user's normal observation of the display screen 3. At the same time, it can also increase the dustproof effect of the display screen 3, making it difficult for dust to enter the display screen 3 and cause damage to the display screen 3.

[0027] A fixed frame 16 is installed on the top of the upright pole 1. A drive motor 17 is installed on the top of the fixed frame 16 through the outer shell. A lead screw 18 is connected to the bottom of the drive motor 17 through a coupling. A threaded sleeve 19 is sleeved on the outside of the lead screw 18. Both sides of the threaded sleeve 19 are connected to a connecting rod 20 that passes through the fixed frame 16 through a rotating shaft. The end of the connecting rod 20 away from the threaded sleeve 19 is connected to a movable frame 21 through a rotating shaft. A tarpaulin 22 is connected between the movable frame 21 and the groove of the fixed frame 16. The two sets of tarpaulins 22 are connected by a rotating shaft. The side of the movable frame 21 away from the tarpaulin 22 is connected to both sides of the fixed frame 16 through a rotating shaft.

[0028] In practical implementation, when the dust detector with screen protection structure needs to protect the dust sampler 5 on the top of the lower support frame 4 and the wind direction and speed detector 23 on the top of the upper support frame 6 from rain, the drive motor 17 can be started. The drive motor 17 will drive the lead screw 18 at the bottom to rotate through the coupling. A threaded sleeve 19 is sleeved on the outside of the lead screw 18, and both sides of the threaded sleeve 19 are connected to connecting rods 20 through rotating shafts. The connecting rods 20 are connected to both sides of the fixed frame 16 through movable slots. Due to the limiting and guiding effect of the movable slots on both sides of the fixed frame 16 on the connecting rods 20, the lead screw 18 will drive the threaded sleeve 19 to slide up and down when rotating. The other end of the connecting rod 20 is connected to one side of the movable frame 21 through a rotating shaft. When the screw sleeve 19 drives one end of the connecting rod 20 to move upward, the connecting rod 20 will rotate through the pivot, thereby causing the other end of the connecting rod 20 to generate a thrust on the movable frame 21. The bottom of the movable frame 21 is connected to both sides of the fixed frame 16 through the pivot. Therefore, when the movable frame 21 is pushed by the connecting rod 20, it will rotate through the pivot. A tarpaulin 22 is connected between the top of the movable frame 21 and the fixed frame 16, and a pivot is connected between the two sets of tarpaulins 22. The tarpaulin 22 will unfold under the action of the movable frame 21. After the tarpaulin 22 is unfolded, it can protect the dust sampler 5 and the wind direction and speed detector 23 at the bottom from rain, preventing the dust sampler 5 and the wind direction and speed detector 23 from being eroded by rainwater.

[0029] Conversely, the drive motor 17 can be started in reverse. The drive motor 17 will drive the screw sleeve 19 to slide downward through the lead screw 18, and pull the movable frames 21 on both sides closer to each other through the connecting rod 20. Since the two sets of tarpaulins 22 are connected by a rotating shaft, the movable frame 21 will cause the tarpaulins 22 to fold when it is being stored, thus making it easier to store the tarpaulins 22.

[0030] See Figure 1 , Figure 2 and Figure 3 It can be seen that, during use, the drive motor 17 can be started as needed, and the connecting rod 20 can be rotated under the cooperation of the lead screw 18 and the screw sleeve 19, and the tarpaulin 22 can be unfolded through the movable frame 21. The tarpaulin 22 can then be used to protect the dust sampler 5 and the wind direction and speed detector 23 from rain.

[0031] In summary, when using this dust detector with a screen protection structure, the upright 1 can be stably fixed to the ground of the construction site with bolts. Then, the dust sampler 5 on the top of the lower support frame 4 can sample and analyze the dust in the air, and then display the dust value on the display screen 3, so that the user can quickly understand the dust value. At the same time, the wind speed and wind direction can be detected by the wind direction and wind direction detector 23 on the top of the upper support frame 6, and the detection results can also be displayed on the display screen 3, so as to facilitate the detection of dust at the construction site. This is the characteristic of the use of the dust detector with a screen protection structure. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
