[0001] This utility model belongs to the field of detection instrument technology, specifically a portable TVOC detector. Background Technology
[0002] A TVOC detector is an instrument used to detect the concentration of total volatile organic compounds (TVOC) in the air. It rapidly measures the TVOC content in the environment through principles such as photoionization, electrochemistry, or infrared absorption. It is widely used in indoor air quality monitoring, industrial site pollution detection, and hazardous gas detection at emergency accident sites, helping people to detect and prevent hazardous gas pollution in a timely manner and protect their health and safety.
[0003] In the existing technology, portable TVOC content detectors are generally equipped with a special storage box for protection to avoid dust and accidental collisions. However, traditional storage boxes are large and inconvenient for staff to carry.
[0004] Therefore, this utility model provides a portable TVOC detector. Utility Model Content
[0005] To address the shortcomings of existing technologies and solve the problem that portable TVOC content detectors are generally equipped with dedicated storage boxes for protection against dust and accidental collisions, but traditional storage boxes are bulky and inconvenient for staff to carry.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The portable TVOC detector of this utility model includes a rectangular plate, and a carrying mechanism is provided at the bottom of the rectangular plate. The carrying mechanism includes:
[0007] The detector assembly includes a set of first fixed blocks fixed to the bottom of a rectangle, a rectangular rod fixed between the opposite sidewalls of the pair of first fixed blocks, a pair of U-shaped blocks slidably connected to the rectangular rod, a storage shell fixed to the bottom of the pair of U-shaped blocks, a circular rod fixed to the inner wall of the storage shell, a rotating block rotatably connected to each of the pair of circular rods, a detector body fixed to the sidewall of the pair of rotating blocks, and the detector body located inside the pair of storage shells; the top of the rectangular plate is provided with an adjustment component for opening the pair of storage shells.
[0008] The locking component is set on the rectangular plate to lock the adjustment component in place.
[0009] Preferably, the adjustment assembly includes a rectangular block fixed to the top of the housing, a first rotating rod rotatably connected to the top of the rectangular block via a first rotating shaft, and a second rotating rod rotatably connected to the end of a pair of first rotating rods away from the rectangular block via a pair of second rotating shafts.
[0010] Preferably, the rectangular plate is rotatably connected to an adjusting rod through a rotating hole. One end of the adjusting rod at the bottom of the rectangular plate is fixedly connected to the center of the top of the second rotating rod, and a knob is fixedly connected to the top end of the adjusting rod at the top of the rectangular plate.
[0011] Preferably, the locking assembly includes a set of locking teeth on the outer circular wall of the knob, a second fixing block is fixedly connected to the top of the rectangular plate, and a sliding groove is provided on the side wall of the second fixing block.
[0012] Preferably, a sliding block is slidably connected in the sliding groove, and the sliding block is connected to the groove wall of the sliding groove by a spring, and a locking tooth is fixedly connected to one side of the sliding block.
[0013] Preferably, a pair of loops are fixed to the top of the rectangular plate, and the loops are located on both sides of the top of the rectangular plate, with handles connected to the pair of loops.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The portable TVOC detector of this utility model opens a pair of storage shells by adjusting the components. During this process, the U-shaped block slides on the rectangular rod to ensure the stability of the movement of the storage shells, and the rotating block slides on the circular rod and can rotate so that the detector body can be exposed at a suitable angle after the storage shells are opened. The internal space of the pair of storage shells is close to the detector body, thereby greatly reducing the space occupied for storage and solving the problem that traditional storage boxes are bulky and inconvenient for staff to carry.
[0016] 2. The portable TVOC detector of this utility model uses a locking component to fix the position of the adjustment rod, thereby fixing the state of the detector body. When the knob is rotated to the appropriate position, the locking teeth, under the action of the spring, engage with the locking teeth on the outer circular wall of the knob, preventing the knob from rotating arbitrarily, thus locking the adjustment component and keeping the detector body in the unfolded or retracted state. When adjustment is required again, the sliding block is manually pressed to overcome the spring force, causing the locking teeth to separate from the locking teeth, and the knob can be rotated again for adjustment. This improves the sealing effect when the storage shell is retracted, preventing the storage shell from opening and affecting the internal environment. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1 to 6 As shown, the portable TVOC detector of this utility model embodiment includes a rectangular plate 1. A portable mechanism is provided at the bottom of the rectangular plate 1. The portable mechanism includes: a detector assembly, including a set of first fixing blocks 2 fixed to the bottom of the rectangular plate, a rectangular rod 3 fixed between the opposite side walls of the pair of first fixing blocks 2, a pair of U-shaped blocks 4 slidably connected to the rectangular rod 3, a storage shell 5 fixed to the bottom of the pair of U-shaped blocks 4, a circular rod 6 fixed to the inner wall of the storage shell 5, a rotating block 7 rotatably connected to each of the pair of circular rods 6, a detector body 8 fixed to the side wall of the pair of rotating blocks 7, and the detector body 8 located inside the pair of storage shells 5. An adjustment component for opening the pair of storage shells 5 is provided at the top of the rectangular plate 1; a locking component is provided on the rectangular plate 1 for locking the adjustment component.
[0027] During operation, a pair of storage shells 5 are opened by adjusting the components. During this process, the loop block 4 slides on the rectangular rod 3 to ensure the stability of the movement of the storage shells 5. The rotating block 7 slides on the circular rod 6 and can rotate, so that the detector body 8 can be exposed at a suitable angle after the storage shells 5 are opened. The internal space of the pair of storage shells 5 is close to the detector body 8, which can greatly reduce the space occupied for storage and solve the problem that traditional storage boxes are large and inconvenient for staff to carry.
[0028] The adjustment assembly includes a rectangular block 9 fixed to the top of the storage shell 5. A first rotating rod 10 is rotatably connected to the top of the rectangular block 9 via a first rotating shaft. A second rotating rod 11 is rotatably connected to one end of the pair of first rotating rods 10 away from the rectangular block 9 via a pair of second rotating shafts.
[0029] A rectangular plate 1 is rotatably connected to an adjusting rod 12 through a rotating hole. One end of the adjusting rod 12 at the bottom of the rectangular plate 1 is fixed to the center of the top of the second rotating rod 11, and a knob 13 is fixed to the other end of the adjusting rod 12 at the top of the rectangular plate 1.
[0030] During operation, the detector body 8 is retracted and unfolded by rotating the adjusting rod 12. Rotating the knob 13 drives the adjusting rod 12 to rotate, which in turn drives the second rotating rod 11 to move. The second rotating rod 11, through the first rotating rod 10, drives the rectangular block 9 and the storage shell 5 to move.
[0031] When the knob 13 is rotated clockwise, the second rotating rod 11 moves upward, causing the first rotating rod 10 to rotate around the first rotating axis, so that the pair of storage shells 5 move away from each other, thereby opening the storage shells 5 and exposing the detector body 8; conversely, when the knob 13 is rotated counterclockwise, the storage shells 5 will store the detector body 8.
[0032] During this process, the loop block 4 slides on the rectangular rod 3 to ensure the stability of the movement of the storage shell 5, and the rotating block 7 slides on the circular rod 6 so that the detector body 8 can be exposed or stored at a suitable angle.
[0033] The locking assembly includes a set of locking teeth 14 on the outer circular wall of the knob 13, a second fixing block 15 fixed to the top of the rectangular plate 1, and a sliding groove 16 on the side wall of the second fixing block 15.
[0034] A sliding block 17 is slidably connected inside the sliding groove 16, and the sliding block 17 is connected to the groove wall of the sliding groove 16 by a spring. A locking tooth 18 is fixedly connected to one side of the sliding block 17.
[0035] During operation, the locking assembly is used to fix the position of the adjusting rod 12, thereby fixing the state of the detector body 8. When the knob 13 is rotated to the appropriate position, the locking tooth 18 is locked into the locking tooth 14 on the outer circular wall of the knob 13 under the action of the spring, preventing the knob 13 from rotating freely, thus locking the adjusting assembly and keeping the detector body 8 in the unfolded or retracted state. When adjustment is required again, the sliding block 17 is pressed manually to overcome the spring force and separate the locking tooth 18 from the locking tooth 14, so that the knob 13 can be rotated again for adjustment. This improves the sealing effect when the storage shell 5 is stored, and prevents the storage shell 5 from opening and affecting the internal environment.
[0036] A pair of loops 19 are fixed to the top of the rectangular plate 1, and the loops 19 are located on both sides of the top of the rectangular plate 1. A handle 20 is connected to the pair of loops 19.
[0037] During operation, a pair of loops 19 fixed to the top of the rectangular plate 1 are used to connect the handle strap 20. The handle strap 20 makes it convenient for users to carry the detector, making it easy to carry and giving the detector good portability.
[0038] Working principle: By adjusting the components, a pair of storage shells 5 are opened. During this process, the loop block 4 slides on the rectangular rod 3 to ensure the stability of the movement of the storage shells 5. The rotating block 7 slides on the circular rod 6 and can rotate, so that the detector body 8 can be exposed at a suitable angle after the storage shells 5 are opened. The internal space of the pair of storage shells 5 is close to the detector body 8, which can greatly reduce the space occupied for storage and solve the problem that traditional storage boxes are large and inconvenient for staff to carry.
[0039] The detector body 8 can be folded up and unfolded by rotating the adjusting rod 12. Rotating the knob 13 drives the adjusting rod 12 to rotate, which in turn drives the second rotating rod 11 to move. The second rotating rod 11, through the first rotating rod 10, drives the rectangular block 9 and the storage shell 5 to move.
[0040] When the knob 13 is rotated clockwise, the second rotating rod 11 moves upward, causing the first rotating rod 10 to rotate around the first rotating axis, so that the pair of storage shells 5 move away from each other, thereby opening the storage shells 5 and exposing the detector body 8; conversely, when the knob 13 is rotated counterclockwise, the storage shells 5 will store the detector body 8.
[0041] During this process, the loop block 4 slides on the rectangular rod 3 to ensure the stability of the movement of the storage shell 5, and the rotating block 7 slides on the circular rod 6 so that the detector body 8 can be exposed or stored at a suitable angle.
[0042] The locking assembly is used to fix the position of the adjusting rod 12, thereby fixing the state of the detector body 8. When the knob 13 is rotated to the appropriate position, the locking tooth 18 is locked into the locking tooth 14 on the outer circular wall of the knob 13 under the action of the spring, preventing the knob 13 from rotating freely, thus locking the adjusting assembly and keeping the detector body 8 in the unfolded or retracted state. When adjustment is required again, the sliding block 17 is pressed manually to overcome the spring force and separate the locking tooth 18 from the locking tooth 14. Then the knob 13 can be rotated again for adjustment. This improves the sealing effect when the storage shell 5 is stored, and prevents the storage shell 5 from opening and affecting the internal environment.
[0043] A pair of loops 19 fixed to the top of the rectangular plate 1 are used to connect the handle strap 20. The handle strap 20 makes it convenient for users to carry the detector, making it easy to carry and giving the detector good portability.
