It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] like Figure 1 As shown, the utility model provides a panel-type air switch protective cover with a lock, including a panel 1, which is rectangular. Figure 6 As shown, a window 11 is provided on the panel 1. One side of the window 11 is used to install an air switch, that is, the air switch is provided on the inner side of the panel 1 to prevent misoperation. A mounting bracket 2 is provided on the other side of the window 11, that is, the mounting bracket 2 is provided on the outer side of the panel 1. The mounting bracket 2 is installed on the panel 1. A protective cover 3 is provided on the mounting bracket 2. A lock slot 31 is provided on the protective cover 3. Figure 2 As shown, a magnetic block 26 and a locking plate 24 are provided on the mounting frame 2, one end of the protective cover 3 is rotatably connected to the mounting frame 2, and the other end of the protective cover 3 cooperates with the magnetic block 26, so that the protective cover 3 closes the window 11, and one end of the locking plate 24 passes through the lock slot 31 and is provided with a padlock.

[0039] It can be understood that by setting the magnetic block 26 to attract the protective cover 3, the protective cover 3 can be opened only under a certain external force to avoid accidental touch, and by setting the lock plate 24, a padlock can be equipped for special management, thereby avoiding the naked air switch from being misoperated by non-professionals, protecting the safety of operators and equipment, such as Figure 5 As shown, the protective cover 3 is closed. Figure 5 No padlock is indicated.

[0040] In some embodiments, as Figure 2 、 8 As shown, the mounting frame 2 includes an upper mounting bar 21 and a lower mounting bar 22 arranged in parallel. A rotation shaft 23 is fixedly provided on opposite sides of the upper mounting bar 21 and the lower mounting bar 22. Two rotation holes 32 are symmetrically provided on the protective cover 3. The rotation shafts 23 are inserted into the rotation holes 32, allowing the protective cover 3 to rotate about the rotation shafts 23. By providing the rotation shafts 23 on both the upper mounting bar 21 and the lower mounting bar 22, the protective cover 3 can rotate about the rotation shafts 23, thereby sealing the window 11.

[0041] Furthermore, the upper mounting bar 21 and the lower mounting bar 22 are both L-shaped, and the upper mounting bar 21 and the lower mounting bar 22 are symmetrically arranged.

[0042] The upper mounting bar 21 and the lower mounting bar 22 are both L-shaped, and each includes a portion perpendicular to the panel 1 and a portion parallel to the panel 1. The portion parallel to the panel 1 can be used to fix to the panel 1, and the portion perpendicular to the panel 1 can be used to set the rotating shaft 23.

[0043] In some embodiments, as Figure 3 、 10 As shown, the mounting bracket 2 includes a locking bar 25 , which is perpendicular to the upper mounting bar 21 and the lower mounting bar 22 . The locking bar 25 is arranged between the upper mounting bar 21 and the lower mounting bar 22 , and the magnetic block 26 is arranged on the locking bar 25 .

[0044] Furthermore, if Figure 2 As shown, the lock plate 24 is vertically fixed on the lock bar 25. When the protective cover 3 is closed, the lock plate 24 can pass through the protective cover 3 and lock the protective cover 3 with a padlock.

[0045] In some embodiments, as Figure 4 As shown, an air switch bracket 4 is provided on one side of the window 11. The air switch bracket 4 is used to fix the air switch. The two ends of the air switch bracket 4 are provided with air switch bracket fixing holes 41. Figure 6 As shown, four first fixing holes 13, two second fixing holes 14, and two third fixing holes 15 are opened on the panel 1. The four first fixing holes 13 are used to fix the upper mounting bar 21 and the lower mounting bar 22, the two second fixing holes 14 are used to fix the locking bar 25, and the two third fixing holes 15 are used to fix the open bracket 4. Since the fixed position of the locking bar 25 corresponds exactly to one of the third fixing holes 15, an avoidance hole 251 corresponding to the open bracket fixing hole 41 is opened on the locking bar 25, so that the locking bar 25 can be fixed to the panel by screws without affecting the fixation of the open bracket 4.

[0046] Furthermore, if Figure 7 As shown, the open bracket 4 is in the shape of a Chinese numeral "X".

[0047] In some embodiments, as Figure 10 As shown, a countersunk hole 261 is formed on the magnetic block 26 , and the magnetic block 26 is fixed to the locking bar 25 by screws passing through the countersunk hole 261 .

[0048] In some embodiments, a transparent window is provided on the protective cover 3 to facilitate the operator to observe the current state of the air switch.

[0049] In some embodiments, as Figure 6 As shown, a mounting opening 12 is provided on the panel 1, and the mounting opening 12 is used for installing an emergency stop button assembly.

[0050] In some embodiments, a fixing hole for the protective cover 3 is opened on the panel 1, and a spring is provided on the protective cover 3. The spring is in a tensioned state, and the two ends of the spring are respectively connected to the protective cover 3 and the mounting frame 2. The spring is arranged near the rotating connection between the protective cover 3 and the mounting frame 2. The fixing hole of the protective cover 3 is used to fix the opened protective cover 3 to the panel 1.

[0051] It can be understood that the spring will always apply a force to the protective cover 3 toward the mounting frame 2, so that after the operator opens the protective cover 3, if the protective cover 3 is not fixed through the fixing hole of the protective cover 3, the protective cover 3 can be automatically closed and pressed against the mounting frame 2 under the action of the spring and the magnetic block 26, thereby preventing misoperation.

[0052] The utility model has the advantages of simple structure, small space occupation, convenient installation and low production cost; specialized personnel can manage the padlock, thereby improving the safety of equipment use.
