Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to an air quality detection device for building construction. Background Art

[0002] During the construction process, it is usually necessary to detect the air quality of the construction site. For example, the patent with publication number CN214041361U discloses an air quality detection equipment for monitoring construction, including a detection device, an anti-collision device is fixedly connected to the outer surface of the detection device, the anti-collision device includes a reinforcement frame, a first spring is fixedly connected to the outer surface of the reinforcement frame, a protective frame is fixedly connected to the side of the first spring away from the reinforcement frame, an anti-slip pad is fixedly connected to the side of the protective frame away from the reinforcement frame, and a fixing device is fixedly connected in a placement groove opened on the back of the detection device.

[0003] The above patent sets a second spring and a clamping sleeve. The second spring can push the clamping sleeve to tightly clamp the user's fingers, thereby achieving adjustment for fingers of different sizes. However, in actual use, the above patent cannot be adjusted to the most suitable wearing space size. The clamping is only achieved by pushing the second spring, so that thicker fingers are clamped more tightly and thinner fingers are clamped more loosely, which can easily cause discomfort to the user's fingers.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and an air quality detection device for construction is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an air quality detection device for building construction to solve the problems existing in the above-mentioned background technology.

[0006] The utility model provides the following technical solutions: an air quality detection device for construction, comprising a flip plate and an air detector main body, a through rectangular opening being provided on one side of the flip plate, a two-way threaded rod one being installed internally and rotatably through the flip plate, a rotating block being fixedly installed on the through end of the two-way threaded rod one, a two-way threaded rod two being fixedly installed on the other end of the two-way threaded rod one, one end of the two-way threaded rod two being rotatably connected to the inner wall of the flip plate, two groups of fixing components being installed through threads on the outer sides of the two-way threads of the two-way threaded rod one and the two-way threaded rod two, the fixing components being slidably arranged on the inner side of the through rectangular opening, the fixing components comprising a movable plate, two movable plates being arranged in number, a sliding groove corresponding to the movable plate being provided on the inner wall of the through rectangular opening, springs being fixedly installed on the surfaces of the two movable plates close to each other, and arc-shaped clamping plates being fixedly installed on the ends of the two springs close to each other.

[0007] Furthermore, two symmetrical sleeves are fixedly installed on one side of the movable plate, a slider is slidably installed inside the sleeve, a connecting rod is fixedly installed on one side of the slider, the connecting rod slides through the slider, and the through ends of the connecting rod are fixedly connected to the arc-shaped clamping plate. When the movable plate moves, the movement of the arc-shaped clamping plate is guided by the connecting rod sliding in the sleeve, thereby avoiding the skewing of the arc-shaped clamping plate and affecting the clamping and fixing effect of the arc-shaped clamping plate.

[0008] Furthermore, the arc-shaped clamping plate has a rubber pad fixedly mounted on its arc-shaped surface, and the rubber pad has anti-skid patterns on its surface. The rubber pad improves the contact comfort between the arc-shaped clamping plate and the user's hand, and the anti-skid patterns can increase the friction between the fingers and the device.

[0009] Furthermore, a guide rod is fixedly installed on the inner wall of the slide groove, and the guide rod slides through the movable plate. The movement of the movable plate is guided by the guide rod, so that the movement of the movable plate is smoother.

[0010] Furthermore, anti-skid protrusions are arranged on the outer side of the rotating block. The anti-skid protrusions arranged on the outer side of the rotating block can increase the friction of the hands of the staff when rotating the rotating block, thereby realizing rapid rotation of the rotating block.

[0011] Furthermore, V-shaped spring clips are fixedly installed on both symmetrical sides of the flip plate, and a slot corresponding to the V-shaped spring clip is opened on the back of the air detector body. By inserting the V-shaped spring clip into the corresponding slot position on the back of the air detector body, the position of the V-shaped spring clip on the back of the air detector body when it is idle is fixed.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Example 1: Please refer to Figure 1-5 The utility model provides an air quality detection device for construction, including a flip plate 100 and an air detector body 101. A through rectangular opening is provided on one side of the flip plate 100. A two-way threaded rod 110 is installed in the internal rotation of the flip plate 100. A rotating block 111 is fixedly installed at the through end of the two-way threaded rod 110. A two-way threaded rod 112 is fixedly installed at the other end of the two-way threaded rod 110. One end of the two-way threaded rod 112 is rotatably connected to the inner wall of the flip plate 100. Two sets of fixing components 102 are installed on the outer sides of the two-way threads of the two-way threaded rod 110 and the two-way threaded rod 112 through threads. The fixing component 102 is slidably arranged on the inner side of the through rectangular opening. The fixing component 102 includes a movable plate 113. The number of movable plates 113 is set to two. A sliding groove corresponding to the movable plates 113 is provided on the inner wall of the through rectangular opening. Springs 114 are fixedly installed on the surfaces of the two movable plates 113 close to each other. An arc-shaped clamping plate 115 is fixedly installed on the ends of the two springs 114 close to each other.

[0023] Working principle: When in use, flip the flip plate 100 from the back of the air detector body 101, and then rotate the rotating block 111. The rotating rotating block 111 drives the two-way threaded rod 110 and the two-way threaded rod 2 112 to rotate, so that the two arc-shaped clamping plates 115 on the two sets of fixed components 102 are respectively moved closer to and away from each other, until the distance between the two arc-shaped clamping plates 115 reaches a suitable position, stop rotating the rotating block 111, and at this time, the user's fingers can be inserted between the two arc-shaped clamping plates 115 at the corresponding position. The reset force of the spring 114 will provide a certain loose buffer space for the inserted fingers to avoid too tight or too loose insertion, which will cause discomfort to the wearing fingers.

[0024] Embodiment 2:

[0025] The difference between the second embodiment and the first embodiment is that: two symmetrical sleeves 120 are fixedly installed on one side of the movable plate 113, a slider 121 is slidably installed inside the sleeve 120, a connecting rod 122 is fixedly installed on one side of the slider 121, the connecting rod 122 slides through the slider 121, the connecting rod 122 is fixedly connected to the arc clamping plate 115 at the through end, the arc clamping plate 115 is fixedly installed with a rubber pad 123 on the arc surface, the rubber pad 123 is provided with anti-skid patterns on the surface, a guide rod 124 is fixedly installed on the inner wall of the slide groove, the guide rod 124 slides through the movable plate 113, an anti-skid protrusion is provided on the outer side of the rotating block 111, and the flip plate 100 is fixed on both sides symmetrically. A V-shaped spring clip 125 is fixedly installed, and a slot corresponding to the V-shaped spring clip 125 is opened on the back of the air detector body 101. During use, when the arc-shaped clamping plate 115 moves, the connecting rod 122 will slide in the sleeve 120 to guide the movement of the arc-shaped clamping plate 115, and the movement of the movable plate 113 on the two groups of fixed components 102 is guided by the guide rod 124. The arc-shaped clamping plate 115 improves the contact comfort and friction of the inserted finger, and the V-shaped spring clip 125 is inserted into the corresponding slot on the back of the air detector body 101 to fix the flip plate 100 in the non-use position on the back of the air detector body 101.

[0026] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
