DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Reference Figure 1-4 The building sealing negative pressure detection device shown includes a base 1, a detection device 2, and a detection cover 3. The detection cover 3 is arranged on the detection device 2. It should be noted that in this embodiment, the installation method of the detection cover 3 can refer to the technical content adopted in a building waterproof sealing negative pressure detection device disclosed in the Chinese patent publication number CN214952029U in the prior art. It will not be repeated here. A transmission cavity is opened in the base 1, and a rotating shaft 4 is rotatably installed on the bottom inner wall of the transmission cavity. The top of the rotating shaft 4 extends to the outside of the base 1 and is fixedly installed with a lower circular plate 5. A screw rod 6 is rotatably mounted on the top of the lower circular plate 5. The detection device 2 is threadedly mounted on the screw rod 6. An upper circular plate 7 is rotatably mounted on the top of the screw rod 6. A lifting motor 8 is fixedly mounted on the top of the upper circular plate 7. The output shaft of the lifting motor 8 is connected to the top of the screw rod 6. A guide assembly is provided on the detection device 2. A linkage shaft 10 is rotatably mounted on the bottom inner wall of the transmission cavity. The linkage shaft 10 is connected to the rotating shaft 4 through a transmission assembly. The top of the linkage shaft 10 extends to the outside of the base 1 and is provided with an operating assembly. The bottom of the base 1 is provided with a moving assembly and a fixed assembly.

[0023] With the above structure, when in use, the device is first moved to a suitable position by the moving assembly and fixed by the fixing assembly. When it is necessary to adjust the height of the detection device 2, the screw 6 is driven to rotate by the lifting motor 8, and then the detection device 2 is driven to a suitable height under the action of the thread and the limiting action of the guide assembly, so as to facilitate detection of different positions. When it is necessary to adjust the detection angle of the detection device 2, the linkage shaft 10 is driven to rotate by the rotating operating assembly, and then the rotating shaft 4 and the lower circular plate 5 are driven to rotate synchronously under the action of the transmission assembly, so that the detection device 2 is driven to rotate synchronously to a suitable angle through the joint action of the lower circular plate 5, the guide assembly, and the upper circular plate 7, so as to facilitate detection in different directions, and has high practicality.

[0024] like Figure 2 As shown, the guide assembly includes a guide rod 9, and a guide hole is opened at the bottom of the detection device 2. The guide rod 9 is slidably installed in the guide hole. The two ends of the guide rod 9 are respectively fixedly connected to the opposite sides of the lower circular plate 5 and the upper circular plate 7. The advantage of this arrangement is that through the arrangement of the guide rod 9, a certain limiting function can be played on the detection device 2.

[0025] Specifically, when the screw 6 rotates, it is easy to drive the detection device 2 to rotate synchronously. Through the setting of the guide rod 9, it can play a certain guiding and limiting function for the detection device 2, avoiding the detection device 2 from rotating synchronously with the rotation of the screw 6, and improving the stability during adjustment.

[0026] like Figure 3 As shown, the transmission assembly includes two sprockets 11, which are fixedly sleeved on the rotating shaft 4 and the linkage shaft 10 respectively. A chain 12 is installed on the two sprockets 11 in meshing relationship. The advantage of this arrangement is that the rotating shaft 4 can be driven to rotate by the rotation of the linkage shaft 10 through the arrangement of the two sprockets 11 and the chain 12.

[0027] Specifically, when the angle of the detection device 2 needs to be adjusted, the linkage shaft 10 is rotated, and the rotating shaft 4 is driven to rotate in the same direction under the meshing action of the two sprockets 11 and the chain 12, and then the lower circular plate 5 is driven to rotate, and the upper circular plate 7 and the detection device 2 are driven to rotate synchronously through the action of the guide rod 9, thereby realizing the angle adjustment of the detection device 2.

[0028] like Figure 3 As shown, the operating component includes a crank 13, the bottom end of the crank 13 is fixedly connected to the top end of the linkage shaft 10. The advantage of this arrangement is that the setting of the crank 13 makes it more convenient for the staff to rotate the linkage shaft 10.

[0029] Specifically, when the staff needs to rotate the linkage shaft 10, they can achieve convenient operation by rotating the handle 13, which is more convenient and labor-saving to use.

[0030] like Figure 3 As shown, a threaded hole is provided on the inner wall of the side of the transmission cavity, and a limit bolt 14 is installed in the threaded hole. The limit bolt 14 is adapted to the linkage shaft 10. The advantage of such an arrangement is that the limit bolt 14 can realize the limiting function of the linkage shaft 10 to prevent it from rotating at will.

[0031] Specifically, when the linkage shaft 10 needs to be rotated, the limit bolt 14 can be released to limit the linkage shaft 10, thereby facilitating its rotation operation. After the adjustment is completed, the limit bolt 14 is rotated to squeeze the linkage shaft 10, thereby limiting it and preventing it from rotating at will.

[0032] like Figure 4 As shown, the mobile component includes a plurality of universal wheels 20, and the plurality of universal wheels 20 are all arranged at the bottom of the base 1. The advantage of such an arrangement is that the arrangement of the plurality of universal wheels 20 can realize the convenient movement function of the entire device.

[0033] Specifically, when the device needs to be moved, the device can be easily moved by pushing the device under the action of the multiple universal wheels 20, and the operation is convenient.

[0034] like Figure 4 As shown, the fixing component includes a suction cup 17, a bottom hydraulic cylinder 15 is provided at the bottom of the base 1, an air pipe 16 is fixedly installed at the output end of the bottom hydraulic cylinder 15, the bottom of the air pipe 16 is connected to the suction cup 17, an exhaust branch pipe is provided on the air pipe 16, an exhaust valve 18 is provided on the exhaust branch pipe, and an air pump 19 is provided on the air pipe 16. The advantage of this arrangement is that the device can be conveniently fixed through the setting of the suction cup 17, and the fixing effect is stable.

[0035] Specifically, when the device needs to be fixed, the bottom hydraulic cylinder 15 drives the suction cup 17 to move downward, so that it is pressed against the ground, and the gas inside the suction cup 17 is discharged through the exhaust valve 18, so that the interior is in a negative pressure state, thereby achieving a better adsorption and fixing effect. When the fixation needs to be released, the air is passed into the suction cup 17 through the air pipe 16 through the air pump 19 to release the negative pressure state, thereby achieving the release fixation function.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
