[0031] In order to enable the personnel in the technical field to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figure 1 and Figure 2 shown, a gate opening load gauge in an embodiment of the present utility model includes a housing 1. A display screen is installed at one end of the housing 1, and a terminal block is installed at the end of the housing 1 away from the display screen. The housing 1 is embedded in the front panel of the power cabinet 3.

[0033] For the safety of the housing 1 during transportation and installation, as Figures 3 to 6 shown, a placing groove 11 is provided on the right side wall of the housing 1, and a first protection component is slidably connected in the placing groove 11. The first protection component includes a first protection plate 12. A rubber strip 16 is bonded to one end of the first protection plate 12, and a second protection plate 13 is bonded to the end of the rubber strip 16 away from the first protection plate 12. The first protection plate 12 covers the end of the housing 1 where the display screen is installed. A second protection component is fixedly connected to the end of the housing 1 away from the end where the display screen is installed, and the second protection component is used to seal the terminal block on the housing 1.

[0034] Specifically, the first protection plate 12, the rubber strip 16 and the second protection plate 13 are all slidably connected in the placing groove 11. When transporting the housing 1, pull the first protection plate 12 to slide the first protection plate 12 out of the placing groove 11. After the first protection plate 12 slides out of the placing groove 11, rotate the first protection plate 12. Under the elastic action of the rubber strip 16, the first protection plate 12 can be parallel to the display screen on the housing 1, and the first protection plate 12 is clamped at the end of the housing 1 where the display screen is installed. At this time, the first protection plate 12, the rubber strip 16 and the second protection plate 13 cover the front end of the housing 1, and the display screen on the housing 1 can be protected.

[0035] In order to enable the first protective plate 12 to withstand a certain impact force and better protect the display screen on the housing 1, as Figures 3 to 8 shown, a locking member 121 is rotatably connected to the first protective plate 12. The locking member 121 includes a rotating column and a pair of locking bars. The rotating column on the locking member 121 penetrates through the first protective plate 12, and the pair of locking bars are integrally formed symmetrically on both end faces of the rotating column. A first limiting plate 14 is welded to the left side wall of the housing 1, and a first through groove 141 matching the locking member 121 is provided on the first limiting plate 14. The locking member 121 penetrates through the first through groove 141. A pair of locking grooves 15 are also provided on the left side wall of the housing 1, and the pair of locking grooves 15 are symmetrically provided on both sides of the first limiting plate 14 respectively.

[0036] Specifically, when the first protective plate 12 is parallel to the display screen on the housing 1, the first protective plate 12 is attached to the first limiting plate 14, and the rotating column on the locking member 121 and the locking bar at the rear end of the rotating column penetrate through the first through groove 141 on the first limiting plate 14. Rotate the locking bar on the front side of the first protective plate 12, and the pair of locking bars will be clamped in the pair of locking grooves 15, and the fixation of the first protective plate 12 can be achieved. At this time, because the first protective plate 12 is locked by the locking member 121, the second protective plate 13 cannot slide in the placement groove 11 either. There is a certain space between the first protective plate 12 and the display on the housing 1, which can strengthen the protection of the display.

[0037] Furthermore, a second limiting plate 17 is welded and connected to the end face of the housing 1 where the display is installed. The end of the second limiting plate 17 far from the housing 1 is flush with the front end of the first limiting plate 14 far from the first limiting plate 14. The second limiting plate 17 and the first limiting plate 14 jointly support the first protective plate 12 to better protect the display screen on the housing 1.

[0038] Furthermore, after the housing 1 is installed on the power cabinet 3, clamping the locking member 121 in the locking groove 15 can also prevent the display screen on the housing 1 from getting damp and prevent accidental touch.

[0039] Preferably, the first protective plate 12 is a transparent acrylic plate, which can withstand a certain force and also facilitate observing the parameters of the display screen on the housing 1.

[0040] When adjusting the opening of the gate, it is necessary to operate the buttons on the housing 1. In order to facilitate fixing the first protective plate 12 in the placement groove 11, a first card slot 171 matching the locking member 121 is provided on the second limiting plate 17.

[0041] Specifically, when operating the button on the operation housing 1, rotate the locking member 121 to disengage the locking member 121 from the locking groove 15. When the locking member 121 coincides with the first through groove 141, rotate the first protective plate 12 so that the first protective plate 12 is on the same horizontal line as the placement groove 11, and then push the first protective plate 12 into the placement groove 11. After the first protective plate 12 enters the placement groove 11, the locking member 121 can be snapped into the first card slot 171 to fix the first protective plate 12, facilitating the operation of the button on the housing 1.

[0042] As Figure 3 , Figure 5 and Figure 7 shown, a plurality of guide rails 131 are integrally formed on the second protective plate 13, and guide grooves 111 matching the guide rails 131 are formed on the groove wall of the placement groove 11. The guide rails 131 are slidably connected in the guide grooves 111. Specifically, during the process of rotating the first protective plate 12 to be parallel to the placement groove 11, when the guide rail 131 blocks the side wall of the first protective plate 12, the first protective plate 12 can be parallel to the placement groove 11, enabling quick operation and saving work efficiency.

[0043] At the same time, during the process of pushing the first protective plate 12 into the placement groove 11, although the first protective plate 12 can be picked up, since the rubber strip 16 is made of a soft material, the second protective plate 13 cannot be well stressed, and the lower wall of the second protective plate 13 away from the rubber strip 16 may scrape against the lower groove wall of the placement groove 11, making it difficult to push the first protective plate 12 into the placement groove 11. The guide rails 131 can strengthen the stability of the second protective plate 13 in the placement groove 11 and also play a guiding role for the second protective plate 13, effectively preventing the situation where the first protective plate 12 cannot be pushed into the placement groove 11.

[0044] As Figure 9 shown, the second protective component includes a protective frame 2 and a third protective plate. The protective frame 2 is integrally formed at the rear end of the housing 1. A second through groove 21 is formed on one side wall of the protective frame 2, and the second through groove 21 penetrates one side wall of the protective frame 2. A second card slot 23 is formed on the other side wall of the protective frame 2, and the third protective plate 22 is inserted into the second card slot 23 after passing through the second through groove 21.

[0045] Specifically, the third protective plate 22 and the second card slot 23 are in an interference fit, and the third protective plate 22 is firmly inserted into the second card slot 23. When the third protective plate 22 is inserted into the second card slot 23, the third protective plate 22 and the protective frame 2 seal the rear end of the housing 1, capable of protecting the terminal block at the rear end of the housing 1 and preventing the terminal block from being damaged. After the housing 1 is installed on the power cabinet 3, pulling out the protective frame 2 from the protective frame 2 enables wiring of the terminal block on the housing 1.

[0046] Further, a drawstring 221 is adhesively attached to the side wall of the third protective plate 22, facilitating the pulling out of the third protective plate 22 inserted in the second card slot 23. The pulled-out third protective plate 22 can be placed inside the power cabinet 3 or on the upper panel of the housing 1. When the housing 1 needs to be removed for maintenance, the third protective plate 22 is re-inserted into the protective frame 2 to protect the terminal on the housing 1.

[0047] During use, when the housing 1 needs to be transported from the manufacturer to the installation site, first, the third protective plate 22 is inserted into the protective frame 2 to protect the terminals on the housing 1. Then, the first protective plate 12 is pulled to slide it out of the placement groove 11, and the first protective plate 12 is rotated to make it fit against the first limiting plate 14. Finally, the locking member 121 is rotated and locked in the locking groove 15 to protect the display screen on the housing 1.

[0048] After the housing 1 is installed on the power cabinet 3, the third protective plate 22 is pulled out of the protective frame 2, and the first protective plate 12 is re-inserted into the placement groove 11. This can protect both the display screen and the terminals on the housing 1 without affecting the installation and use of the housing 1.

[0049] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
