Description

Technical Field

[0001] The utility model relates to a rapid fixing and sealing device for a wind speed detector. Background Art

[0002] The common method of detecting wind speed in an air duct is to open the wind speed detection port on the duct and then insert a handheld wind speed detector into the duct for detection. The disadvantage of this detection method is that it is affected by manual holding. During the detection process, the wind speed detector will move up and down, swing, and rotate, affecting the accuracy of the wind speed detection result. In addition, since the wind speed detection port is open during the process, the wind in the duct will overflow from here, which will also cause deviations in the wind speed detection results.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The air duct is provided with a detection port, which is a hollow columnar structure protruding from the wall of the air duct and penetrating the air duct radially. The wind speed detector is handheld. The end of the rod with the detection head is inserted into the air duct from the detection port through the detection rod. The wind speed in the air duct is detected by the detection head. Please refer to Figures 1 to 3 The wind speed detector quick fixing sealing device of this embodiment is used for limiting the detection rod and temporarily sealing the detection port. It is detachably assembled by a locking structure 1 and a sealing structure 2. The formed overall structure forms a through channel 21 in the center, one end of which is provided with a sealing ring 22 as a sealing end, and the other end is provided as an exposed end. An indicator mark 12 protruding radially outward along the channel 21 is formed on the outer peripheral wall of the exposed end. The detection rod passes through the channel 21 with one end with a detection head toward the sealing end, and the detection head is exposed. The detection rod maintains contact with the channel 21 at the exposed end. The detection rod is tightened along the radial direction of the rod body by a locking screw radially penetrating one side of the wind speed detector quick fixing sealing device along the channel 21, and is maintained in contact with the outer peripheral wall of the rod body by a pair of limit screws parallel to the tangent direction of the rod body, symmetrically arranged on both sides of the rod body, and penetrating the wind speed detector quick fixing sealing device.

[0023] The wind speed detector quick-fix sealing device with a detection rod can be coaxially mounted on the detection port through the sealing end. The channel 21 and the detection port are sealed at the sealing end by a sealing ring 22, and the detection head passes through the detection port and extends into the air duct along the radial direction of the air duct.

[0024] In a specific implementation, the corresponding structural setting of the device also includes:

[0025] The free end of the detection port can be sealed by a cover.

[0026] The sealing structure 2 is a through hollow sleeve structure with a channel 21 formed in the center inside. One end is provided with a sealing ring 22 as a sealing end. A locking screw hole 23 for a locking screw to pass through is opened on the peripheral wall of the sealing end. The other end is an exposed end, which is cut into two along the central axis from the end face, and half is empty. The empty part is assembled by a locking structure 1 with matching outer dimensions. A pair of limiting screw hole channels for the limiting screw to pass through are formed between the locking structure 1 and the sealing structure 2 according to the position and outer dimensions of a pair of limiting screws. The limiting screw hole channels are formed by aligning the first limiting screw hole 11 on the locking structure 1 with the second limiting screw hole 24 on the sealing structure 2. An L-shaped step surface 25 is formed on the sealing structure 2 corresponding to the second limiting screw hole 24 to provide an operating space for the passing of the limiting screw.

[0027] The diameter of the exposed end of the hole 21 is set corresponding to the outer diameter of the detection rod.

[0028] The indicator mark 12 is plate-shaped, perpendicular to the central axis of the hole 21 , and is arranged on the locking structure 1 .

[0029] The detection rod with the detection head is in a columnar rod structure, and the overall outer diameter is not larger than the aperture of the hole.

[0030] When applying:

[0031] The device with the detection rod is installed on the detection port through the sealing end. The device and the detection port can be temporarily sealed by a sealing ring. The detection head carried by the detection rod passes through the hole and the detection port of the device and extends into the air duct. In order to facilitate the adjustment of the relative position between the detection head and the air duct, the device is provided with an indicator mark. The indicator mark can be used to easily and intuitively determine whether the detection head is set along the radial direction of the air duct. After adjusting the position of the detection head, the locking screw and a pair of limit screws are used to lock and limit, which can prevent the detection rod from rotating, moving or swinging during the detection process, thereby ensuring that the detection result is not affected.
