Description

Technical Field

[0001] The utility model relates to the technical field of speed regulator detection, in particular to a detection device for a DC speed regulator. Background Art

[0002] After searching, it was found that the prior art, such as the Chinese patent (application number: CN202020791293.0), discloses a DC speed regulator voltage detection device, including a knob. Turning the knob rotates the shaft. The rotation of the shaft drives the screw fixedly connected to its bottom to rotate. The rotation of the screw drives the screw sleeve to move. The horizontal plate and L-shaped plate on the top of the screw sleeve are plugged into the guide rod to limit the rotation of the screw sleeve. Therefore, the screw sleeve can only rise or fall under the drive of the screw. The rise or fall of the screw sleeve drives the magnetic block fixedly connected to its bottom to rise or fall. When the magnetic block descends and extends out of the first control box and the second control box through the movable groove, the magnetic block will attract each other with the magnetic sheet on the top of the DC speed regulator, and the voltage detector is fixed to the top of the DC speed regulator by magnetic force. The design is novel, which solves the problem that traditional voltage detection devices generally cannot be installed on the DC speed regulator, and has the advantage of convenient installation of the voltage detection device on the DC speed regulator.

[0003] However, the technical structure disclosed in the above patent is complex, and the installation of the voltage detector on the DC speed regulator by magnetic attraction is very unstable and very easy to detach. Finally, the voltage detector is not flexible enough to use on the DC speed regulator. If there are other objects on the top of the DC speed regulator blocking the installation of the voltage detector, the use of the voltage detector is not flexible enough. Therefore, improvements are needed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a detection device for a DC speed regulator, which solves the problems mentioned in the background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A detection device for a DC speed regulator comprises a mounting round rod whose lower end is fixed at the top center of the DC speed regulator, a voltage detector is rotatably mounted on the mounting round rod, an ear plate is fixed to the rear bottom of the voltage detector, a round hole is vertically opened on the ear plate, the round hole is rotatably matched with the mounting round rod, and a locking mechanism is arranged at the upper end of the mounting round rod.

[0007] Specifically in the utility model, the mounting round rod is a threaded rod, the locking mechanism includes a nut threadedly fitted on the upper end of the mounting round rod, a structure for pressing the ear plate is provided on the lower surface of the nut, the structure for pressing the ear plate includes a pressing ring mounted on the mounting round rod, the pressing ring is pressed on the top of the ear plate, and a plurality of connecting rods arranged at equal intervals are fixed between the upper annular surface of the pressing ring and the lower surface of the nut.

[0008] In order to facilitate wiring, a wiring cavity is opened downward on the upper end of the mounting round rod, the lower end of the wiring cavity is connected to the outlet hole of the DC speed regulator, and a plurality of wiring notches arranged at equal intervals are opened on the cavity wall of the upper end of the wiring cavity.

[0009] In order to prevent dust and water from directly entering the DC speed regulator, a sealing piece is fixed on the top of the inner ring surface of the nut.

[0010] Compared with the prior art, the utility model has the following beneficial effects: by rotating the nut up and down, the voltage detector can be rotated around the mounting round rod, thereby making the use of the voltage detector more flexible, and it can also be determined whether to lock the voltage detector on the DC speed regulator according to the actual situation. The cable arrangement cavity can arrange the data cables to prevent them from being messy, and the length of the data cables extending out of the mounting round rod can be determined according to actual needs, thereby preventing the data cables from being messy again.

[0017] 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.

[0018] like Figure 1-3 , Figure 5 As shown, the utility model provides a detection device for a DC speed regulator, comprising a mounting round rod 1 whose lower end is fixed at the top center of a DC speed regulator X, a voltage detector 2 is rotatably mounted on the mounting round rod 1, an ear plate 3 is fixed to the rear bottom of the voltage detector 2, a circular hole is vertically opened on the ear plate 3, the circular hole is rotatably matched with the mounting round rod 1, and a locking mechanism is arranged at the upper end of the mounting round rod 1.

[0019] like Figure 2-4 As shown, in the utility model, the mounting round rod 1 is a threaded rod, and the locking mechanism includes a nut 4 threadedly fitted on the upper end of the mounting round rod 1, and a structure for pressing the ear plate 3 is provided on the lower surface of the nut 4. The structure for pressing the ear plate 3 includes a pressing ring 5 mounted on the mounting round rod 1, and the pressing ring 5 is pressed on the top of the ear plate 3. A plurality of connecting rods 6 arranged at equal intervals are fixed between the upper annular surface of the pressing ring 5 and the lower surface of the nut 4.

[0020] like Figure 4 As shown, in order to facilitate wiring, a wiring cavity 1-1 is opened downward on the upper end of the mounting round rod 1, the lower end of the wiring cavity 1-1 is connected to the outlet hole on the DC speed regulator X, and a plurality of wiring notches 1-2 arranged at equal intervals are opened on the cavity wall of the upper end of the wiring cavity 1-1.

[0021] like Figure 4-5 As shown, in order to prevent dust and water from directly entering the DC speed regulator X, a sealing piece 7 is fixed to the top of the inner ring surface of the nut 4.

[0022] Finally, the most important contribution of the present invention is that by rotating the nut 4 up and down, the voltage detector 2 can be rotated around the mounting rod 1, thereby making the use of the voltage detector 2 more flexible. It can also be determined whether to lock the voltage detector 2 on the DC speed regulator X according to the actual situation. The wiring cavity 1-1 can arrange the data cable X-1 to prevent it from being messy. It can also determine the length of the data cable X-1 extending out of the mounting rod 1 according to actual needs, thereby preventing the data cable X-1 from being messy again.

[0023] The working principle of the utility model is as follows: the ear plate 3 is installed on the mounting round rod 1, and the voltage detector 2 is rotated according to actual needs to make the ear plate 3 rotate around the mounting round rod 1. According to actual conditions, whether to lock the ear plate 3 is selected. If the ear plate 3 is not locked, the nut 4 is not rotated downward all the time, so that there is a gap between the pressure ring 5 and the ear plate 3. When the ear plate 3 needs to be locked, the nut 4 is turned downward, and the pressure ring 5 is driven to rotate downward through the connecting rod 6 until the pressure ring 5 is pressed against the top of the ear plate 3 to achieve locking of the ear plate 3. When arranging the wires, multiple data cables X-1 of the DC speed regulator X extend from the wire outlet hole and gather in the wire arranging cavity 1. -1, the free end of the data cable X-1 is pulled out from the cable cavity 1-1. The length of the data cable X-1 pulled out from the cable cavity 1-1 can be determined according to actual conditions, and the rest is stored in the cable cavity 1-1 to prevent the data cable X-1 from being exposed outside the DC speed regulator X and being damaged and messy during the process. The data cable X-1 is discharged from the cable notch 1-2. Here, when the pressure ring 5 is locked on the ear plate 3, the lower surface of the nut 4 does not completely cover the cable notch 1-2, so that the data cable X-1 will be located between the bottom of the cable notch 1-2 and the lower surface of the nut 4, preventing the data cables X-1 from crossing and disordering.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
