[0035] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0036] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0037] The following is combined with Figure 1 To Attachment Fig.10 The specific implementation modes of the present utility model are described in detail.

[0038] A portable ambient air monitoring device according to an embodiment of the utility model comprises a base 1, a mounting member 33, mobile wheels 3 and a monitoring device 2. The base 1 has a space for storing the mobile wheels 3 and the monitoring device 2. When the monitoring device is in a complex road condition and it is inconvenient to move on the ground via the mobile wheels 3, the mobile wheels 3 and the monitoring device 2 can be stored in the base 1, thereby reducing the space occupied by the device and making it easier to carry.

[0039] Specifically, the mounting member 33 is hingedly connected to the base 1, and the moving wheel 3 is mounted on the mounting member 33. The moving wheel 3 on the mounting member 33 can be stored in the base 1 through the relative rotation between the mounting member 33 and the base 1. Generally speaking, the flexibility and stability of the structure are inversely proportional. The higher the flexibility of the structure, the lower the stability; the lower the flexibility of the structure, the higher the stability. The mounting member 33 serves as an intermediate member connecting the moving wheel 3 and the base 1, providing a mounting platform for the moving wheel 3, and the structure that requires the moving wheel 3 to rotate relative to the base 1 is designed between the mounting member 33 and the base 1, so as to avoid the moving wheel 3 having the function of flipping while having the rolling function, reduce the flexibility of the moving wheel 3, and thus improve the stability of the moving wheel 3 when rolling.

[0040] As for the moving wheel 3 itself, a universal wheel with a locking function can be used to meet the mobility requirements of the monitoring equipment.

[0041] In addition, the mounting member 33 and the base 1 are connected by a hinge with a locking function. Through the locking function of the hinge, the mounting member 33 and the base 1 can be locked in a suitable position after relative rotation, so as to prevent the mounting member 33 and the base 1 from rotating relative to each other during the rolling use of the moving wheel 3, thereby affecting the normal use of the moving wheel 3. Specifically, there are two common states of the moving wheel 3: the use state and the storage state. In this embodiment, the hinge between the mounting member 33 and the base 1 is set to two locking positions, that is, when the moving wheel 3 is in the use state and the storage state, the hinge between the mounting member 33 and the base 1 is locked to ensure the stability of the moving wheel 3 in the use state and the storage state.

[0042] The moving wheels 3 maintain stability when in use, which can improve the stability of the entire device during movement, and the moving wheels 3 maintain stability when in the storage state, which can prevent the moving wheels 3 from suddenly unfolding in the storage state to affect the carrying of the device.

[0043] The monitoring device 2 includes a mounting rod 23 and a monitoring instrument 24. One end of the mounting rod 23 is used to mount the monitoring instrument 24, and the other end is hinged to the base 1. The monitoring device 2 is stored in the base 1 by rotating the mounting rod 23 relative to the base 1. It should be noted that the monitoring instrument 24 is a special instrument. When the monitoring device is not in use, the monitoring instrument 24 is generally stored separately, that is, in this embodiment, the monitoring instrument 24 is installed with the mounting rod 23 in a detachable fixed connection. Before the monitoring device 2 is stored in the base 1, the monitoring instrument 24 needs to be removed from the mounting rod 23 and stored separately. The space range and size of the base 1 for storing the monitoring device 2 only need to consider the storage of the components of the monitoring device 2 other than the monitoring instrument 24.

[0044] Of course, in other embodiments, the monitor 24 can be stored in the base 1 together with the mounting rod 23, so that when the monitoring device is switched between an unused state and an used state, the steps of installing the monitor 24 and the mounting rod 23 are reduced, making the switching of the monitoring device faster and more convenient.

[0045] In addition, the mounting rod 23 may be a telescopic rod to meet the needs of the monitor 24 for monitoring ambient air at different heights.

[0046] In this embodiment, the base 1 has a receiving groove 112 for receiving the monitoring device 2 and a receiving space 7 for receiving the moving wheel 3. The receiving groove 112 and the receiving space 7 can be reserved during the production, manufacturing, and assembly process of the base 1, or can be processed later. It should be noted that the storage referred to in this embodiment does not mean that the object is completely hidden, but that the space occupied by the device in the stored state is smaller than the space occupied in the use state. In this embodiment, the moving wheel 3 and the monitoring device 2 are stored to reduce the range of the device in the height direction.

[0047] Specifically, the base 1 includes a first mounting frame 11 and a second mounting frame 12 in the form of an elongated strip. The first mounting frame 11 is rotatably connected to the second mounting frame 12 , and the rotation axis is perpendicular to the length direction of the first mounting frame 11 and the second mounting frame 12 .

[0048] Through the relative rotation of the first mounting frame 11 and the second mounting frame 12, the first mounting frame 11 and the second mounting frame 12 can maintain a parallel state. At this time, the range of the entire base 1 along the direction of the rotation axis of the first mounting frame 11 and the second mounting frame 12 is small, which plays the effect of storing the base 1 itself; in addition, through the relative rotation of the first mounting frame 11 and the second mounting frame 12, the first mounting frame 11 and the second mounting frame 12 can also maintain a crossed state, such as along the direction of the rotation axis of the first mounting frame 11 and the second mounting frame 12, the entire base 1 is in a "cross" shape. At this time, the range of the base 1 along the direction of the rotation axis of the first mounting frame 11 and the second mounting frame 12 is large, and the stability of the entire base 1 is good, thereby improving the stability of the entire device during use.

[0049] The mounting member 33 and the moving wheel 3 are installed on at least one of the first mounting frame 11 and the second mounting frame 12. In this embodiment, the mounting member 33 and the moving wheel 3 are installed on the ends of the first mounting frame 11 and the second mounting frame 12 along the length direction, that is, a total of four moving wheels 3 are provided on the base 1, and the four moving wheels 3 are of the same specifications. In other embodiments, the mounting member 33 and the moving wheel 3 can also be installed only on the first mounting frame 11 or the second mounting frame 12, and the other mounting frame is used to improve the stability of the base 1 through relative rotation.

[0050] In this embodiment, in order to avoid collision and interference between the first mounting frame 11 and the second mounting frame 12 during the relative rotation of the moving wheels 3, the positions and lengths of the first mounting frame 11 and the second mounting frame 12 are set accordingly. Specifically, the first mounting frame 11 and the second mounting member 33 are distributed along the height direction, and the length of the mounting member 33 located above is greater than the length of the mounting frame located below. In this embodiment, the first mounting frame 11 is located above the second mounting frame 12 and the length of the first mounting frame 11 is greater than the length of the second mounting frame 12. When the moving wheels 3 are in use, the bottom surfaces of the four moving wheels 3 are on the same plane.

[0051] In addition, for the sake of convenience in distinction, the moving wheel 3 on the first mounting frame 11 is called the first universal wheel 31, and the moving wheel 3 on the second mounting frame 12 is called the second universal wheel 32. The first universal wheel 31 and the second universal wheel 32 located on the left are taken as examples for specific description. In the use state, the first universal wheel 31 and the second universal wheel 32 are both vertically arranged. During the storage process, the first universal wheel 31 rotates 90° counterclockwise, and the second universal wheel 32 rotates 90° clockwise. At this time, the lower ends of the first universal wheel 31 and the second universal wheel 32 are higher than the lower end of the second mounting frame 12. The storage space 7 in the base 1 refers to: the space range between the lower side surface of the first mounting frame 11 and the lower side surface of the second mounting frame 12. In the present embodiment, it is mainly used to reduce the range of the base 1 and the moving wheel 3 in the height direction, and the range in the front and back and left and right directions does not need to be strictly limited.

[0052] Similarly, the first universal wheel 31, the second universal wheel 32 and the storage space 7 on the right side can be symmetrically arranged and operated accordingly.

[0053] In a further configuration, the first mounting frame 11 and the second mounting frame 12 are rotatably connected via a rotating shaft 5. In this embodiment, the second mounting frame 12 is fixedly connected and rotatably connected, the rotating shaft 5 is rotatably connected to the first mounting frame 11 via a bearing, the axial end of the rotating shaft 5 facing the first mounting frame 11 is ball-jointed with the mounting rod 23, and the rotating shaft 5 has a plug-in portion 52, and the mounting rod 23 has a socket 22 for plugging the plug-in portion 52. When the monitoring device 2 is in the storage state, the plug-in portion 52 can be plugged into the socket 22 to limit the rotation of the mounting rod 23 relative to the first mounting frame 11.

[0054] Specifically, a through hole 11 is opened on the first mounting frame 11 for passing the mounting shaft 5, the through hole 11 is connected to the accommodating groove 112, and a spherical connecting portion 51 is provided at the center of the upper end of the rotating shaft 5; one end of the mounting rod 23 is used for mounting the monitor 24, and the other end has a ball head 21 adapted to the connecting portion 51, so as to realize a ball-jointed connection between the mounting rod 23 and the rotating shaft 5, so that the rotation of the mounting rod 23 relative to the base 1 and the self-rotation of the rotating shaft 5 will not interfere with each other.

[0055] In addition, the plug-in portion 52 is arranged at the upper end of the rotating shaft 5. When the monitoring device 2 is in the storage state, the plug-in portion 52 can be inserted into the socket 22 through the rotation of the rotating shaft 5 to limit the rotation of the mounting rod 23 relative to the first mounting frame 11, that is, when the plug-in portion 52 is inserted into the socket 22, the monitoring device 2 cannot be removed from the accommodating groove 112 for use, so as to reduce the situation where the monitoring device 2 accidentally escapes from the accommodating groove 112.

[0056] When the plug-in portion 52 and the socket 22 are in a plug-in state, the first mounting frame 11 and the second mounting frame 12 are parallel in length direction. Specifically, the rotation of the shaft 5 will drive the second mounting frame 12 to rotate, so as to change the angle between the first mounting frame 11 and the second mounting frame 12, and the rotation of the shaft 5 will drive the plug-in portion 52 to rotate. Therefore, when the plug-in portion 52 and the socket 22 are in a plug-in state, the first mounting frame 11 and the second mounting frame 12 are parallel in length direction. At this time, if the shaft 5 remains stopped and does not rotate, the angle between the first mounting frame 11 and the second mounting frame 12 will not change, and the plug-in portion 52 and the socket 22 will still remain in a plug-in state, so that the monitoring device 2 remains in a storage state, improving the safety of use.

[0057] When the first mounting frame 11 and the second mounting frame 12 are parallel, the stability of the entire base 1 is poor. At this time, if the monitoring device 2 is rotated and unfolded from the storage state, the center of gravity of the entire device will be increased, which may easily cause tipping.

[0058] In a further configuration, a widening platform 121 is provided on the base 1 to increase the width of the first mounting frame 11 and the second mounting frame 12 and increase the weight of the base 1, so as to avoid the center of the device being too high after the monitoring device 2 is deployed and reduce the risk of tipping. In this embodiment, a circular widening platform 121 is provided at the center of the second mounting frame 12.

[0059] In this embodiment, a telescopic support member 6 is hinged between the mounting rod 23 and the first mounting frame 11, and a triangular stable structure is formed between the telescopic support member 6, the mounting rod 23 and the first mounting frame 11 to improve the stability of the monitoring device 2 in use. Specifically, the telescopic support member 6 is a telescopic gas strut, one end of which is hinged to the mounting rod 23, and the other end is hinged to the first mounting frame 11.

[0060] In addition, when the monitoring device 2 is in the storage state, the telescopic support member 6 is located below the monitoring device 2 , and a groove 113 is provided at the bottom of the accommodating groove 112 for accommodating the telescopic support member 6 , so as to achieve an avoidance effect.

[0061] In a further configuration, the monitoring device of this embodiment further includes a positioning assembly 4 for positioning the rotational position between the first mounting frame 11 and the second mounting frame 12. The positioning assembly 4 includes a positioning pin 41 and an elastic member 42, wherein the elastic member 42 is fixed between the positioning pin 41 and the first mounting frame 11, and the positioning pin 41 is tapered at one end away from the first mounting frame 11; a plurality of positioning holes 123 are provided on the second mounting frame 12, and the positioning holes 123 are circumferentially distributed around the rotation axis of the first mounting frame 11 and the second mounting frame 12, and when the positioning pin 41 and the positioning hole 123 are in a plugged state, the tapered surface of the positioning pin 41 abuts against the edge of the positioning hole 123.

[0062] Specifically, three positioning holes 123 are arranged on the second mounting frame 12, and the circumferential angle between adjacent positioning holes 123 is 45°, that is, there are three states between the first mounting frame 11 and the second mounting frame 12: parallel, vertical and at a 45° angle. When the positioning pin 41 and the positioning hole 123 are in the plug-in state, when the first mounting frame 11 and the second mounting frame 12 are to be rotated relative to each other, the elastic force of the elastic member 42 needs to be overcome so that the positioning pin 41 can be separated from the positioning hole 123. At this time, the first mounting frame 11 and the second mounting frame 12 can rotate relative to each other, that is, the setting of the elastic member 42 limits the free rotation of the first mounting frame 11 and the second mounting frame 12 to a certain extent to improve the stability; the distribution of the positioning holes 123 plays a positioning role in the relative rotation of the first mounting frame 11 and the second mounting frame 12.

[0063] The second mounting frame 12 is also provided with a limiting portion 122, which can abut against the positioning pin 41, and is used to limit the relative angle range between the first mounting frame 11 and the second mounting frame 12. In this embodiment, the limiting portion 122 is a boss on the second mounting frame 12, and has a first limiting surface 124 and a second limiting surface 125, so that the rotation range of the positioning pin 41 is between the three positioning holes 123. When the positioning pin 41 is plugged into the positioning holes 123 on both sides, the positioning pin 41 simultaneously maintains an abutting state with the limiting surface on the limiting portion 122. Under the limiting action of the limiting portion 122, the relative rotation angle range between the first mounting frame 11 and the second mounting frame 12 is 0 to 90°.

[0064] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0065] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
