Description

Technical Field

[0001] The utility model relates to the field of electrical appliance assembly, in particular to a fixing frame for an air switch. Background Art

[0002] Air switches are widely used in buildings and equipment. The back side of the air switch is provided with a corresponding card slot, and elastic buckles are provided below the card slot. The elastic buckle moves downward to increase the opening of the entire card slot. After the card slot is connected to the mounting bar, the elastic buckle rebounds to fix it. The elastic buckle may become loose after long-term use or under the action of external force, which may cause the air switch to be loose and have a small fixing force. It is easy to fall or move during operation, which will affect the normal operation of the power supply. For this reason, we designed a fixing bracket for the air switch. Utility Model Content

[0003] In order to solve the technical problem that the air switch is not tightly engaged and has a small fixing force when subjected to external force or vibration of mechanical equipment, the utility model provides a fixing bracket for the air switch.

[0004] The utility model is implemented by the following technical scheme: a fixing bracket for an air switch, comprising a mounting bracket, a movable slide plate and a contact seat, the air switch is clamped on the front side of the mounting bracket, the mounting bracket comprises a mounting plate and a clamping edge, the upper and lower ends of the front side surface of the mounting plate are bent forward to form a clamping edge, and the clamping edge is designed to be parallel to the mounting plate, a movable slide plate is provided on the mounting plate for sliding left and right, a contact seat is provided below the front side surface of the movable slide plate for sliding up and down, and two buckles below the air switch abut against the upper surface of the contact seat.

[0005] As a further improvement of the above-mentioned scheme, a plurality of equally spaced mounting strip holes are formed through the front and rear surfaces of the mounting plate of the mounting frame. The design of the mounting strip holes facilitates fixing the mounting frame in the corresponding electrical box, and a transversely arranged movable sliding hole is provided at the bottom end of the mounting plate. The design of the movable sliding hole facilitates the movement of the movable slide plate, so that the movable slide plate and the contact seat can be moved to the appropriate position as needed, and the air switch can be quickly fixed and limited.

[0006] As a further improvement of the above scheme, a plug-in plate is formed by cutting away the parts above the front and rear side surfaces of the movable slide, and the plug-in plate slides through the movable slide hole and is placed above it, and the front side surface of the plug-in plate is connected to a mounting slide by screws, and the mounting slide is in close contact with the mounting frame, which facilitates the installation and disassembly of the movable slide, and a suitable number of movable slides can be placed as needed to correspond to the same number of air switches.

[0007] As a further improvement of the above scheme, the lower half of the rear side surface of the movable slide is recessed forward to form a movable slide groove, and the lower half of the front and rear surfaces of the movable slide are penetrated backward to form an adjustment slide hole, the adjustment slide hole is connected to the movable slide groove, and a fixed slider is slidably placed in the movable slide groove, thereby facilitating the adjustment of the height of the contact seat so that it can be limited after the air switch is installed.

[0008] As a further improvement of the above scheme, a fixed slider is slidably arranged in the movable slide groove, threaded holes are formed on the front and rear sides of the fixed slider, and the rear surface of the fixed slider is flush with the rear surface of the movable slide plate, and the rear surface of the movable slide plate is flush with the rear surface of the mounting plate. When the mounting frame is fixed to the electrical box or wall by screws, the fixed slider and the movable slide plate will also contact the electrical cabinet or wall, thereby being able to support it.

The fixed slider has a square structure, and the fixing bolt does not rotate when it rotates, so that the fixing bolt can move inward, and tightening the fixing bolt can make the contact seat fit tightly against the surface of the moving slider;

[0010] Parts are cut off on both sides of the front end of the contact seat to form abutment portions, and the spacing between the two abutment portions matches the spacing between the two buckles below the air switch, and the buckles are in contact with the abutment portions, which can limit the movement of the air switch and the movable slide, so that the two are connected as one and can only move together without separation.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model provides a movable slide on the mounting frame, and a contact seat that moves up and down is provided on the movable slide. After the air switch is fixed above the mounting frame, the contact seat can limit the buckle thereof, so that it cannot move downward, thereby preventing it from falling loose, thereby improving stability;

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example:

[0022] Please combine Figure 1-Figure 4 A fixing frame for an air switch in this embodiment includes a mounting frame 1, a movable slide plate 3 and a contact seat 4. The air switch 2 is clamped on the front side of the mounting frame 1. The mounting frame 1 includes a mounting plate 11 and a clamping edge 13. The upper and lower ends of the front side surface of the mounting plate 11 are bent forward to form a clamping edge 13, and the clamping edge 13 is designed to be parallel to the mounting plate 11. A movable slide plate 3 is provided on the mounting plate 11 for sliding left and right. A contact seat 4 is provided below the front side surface of the movable slide plate 3 for sliding up and down. The two buckles 21 below the air switch 2 abut against the upper surface of the contact seat 4.

[0023] A plurality of equally spaced mounting strip holes 12 are formed through the front and rear surfaces of the mounting plate 11 of the mounting frame 1. The mounting strip holes 12 are designed to facilitate fixing the mounting frame 1 in the corresponding electrical box, and a transversely arranged movable slide hole 14 is provided at the bottom end of the mounting plate 11. The movable slide hole 14 is designed to facilitate the movement of the movable slide plate 3, so that the movable slide plate 3 and the contact seat 4 can be moved to appropriate positions as needed, and the air switch 2 can be quickly fixed and limited.

[0024] A plug-in plate is formed by cutting away the parts above the front and rear side surfaces of the movable slide plate 3, and the plug-in plate slides through the movable slide hole 14 and is placed above it, and the front side surface of the plug-in plate is connected to the mounting slide plate 31 by screws. The mounting slide plate 31 is in close contact with the mounting frame 1, which facilitates the installation and disassembly of the movable slide plate 3, and a suitable number of movable slide plates 3 can be placed as needed to correspond to the same number of air switches 2.

[0025] The lower half of the rear side surface of the movable slide plate 3 is recessed forward to form a movable slide groove 33, and the lower half of the front and rear surfaces of the movable slide plate 3 are penetrated backward to form an adjustment slide hole 32, which is connected to the movable slide groove 33, and a fixed slider 6 is slidably placed in the movable slide groove 33, thereby facilitating the adjustment of the height of the contact seat 4 so that it can be limited after the air switch 2 is installed.

[0026] A fixed slider 6 is slidably arranged in the movable slide groove 33, and threaded holes are formed on the front and rear sides of the fixed slider 6. The rear surface of the fixed slider 6 is flush with the rear surface of the movable slide plate 3, and the rear surface of the movable slide plate 3 is flush with the rear surface of the mounting plate 11. When the mounting frame 1 is fixed to the electrical box or wall by screws, the fixed slider 6 and the movable slide plate 3 will also contact the electrical cabinet or wall, thereby being able to support it.

[0027] The front and rear surfaces of the contact seat 4 are penetrated with screw holes, and the screw holes are threadedly connected with fixing bolts 5, and the tail ends of the fixing bolts 5 are threadedly connected to the threaded holes of the fixing slider 6. The fixing slider 6 is a square structure, and the fixing bolts 5 will not rotate when the fixing bolts 5 rotate, so that the fixing bolts 5 can move inwards. Tightening the fixing bolts 5 can make the contact seat 4 fit tightly against the surface of the moving slide 3.

[0028] Parts are cut off on both sides of the front end of the contact seat 4 to form abutment portions 41. The spacing between the two abutment portions 41 matches the spacing between the two buckles 21 below the air switch 2, and the buckles 21 are in contact with the abutment portions 41, which can limit the movement of the air switch 2 and the movable slide 3, so that the two are connected as one and can only move together without separation.

[0029] The implementation principle of a fixing frame for an air switch 2 in the embodiment of the present application is as follows: the mounting frame 1 is fixed to the corresponding wall or electrical cabinet by screws, and then the movable slide plate 3 is plugged into the appropriate position of the movable slide hole 14 in the mounting frame 1 according to the position where the air switch 2 needs to be installed, and the mounting slide plate 31 is fixed to the plug-in plate above the movable slide plate 3 by screws, so that the movable slide plate 3 and the mounting frame 1 are tightly fitted together for fixing, and then the buckle 21 of the air switch 2 can be moved downward to enlarge the opening of the card slot on its rear side, and then it is clamped on the upper and lower two of the mounting frame 1. The clamping edge 13 is then inserted into the cross hole of the fixing bolt 5, and the fixing bolt 5 and the contact seat 4 are moved upward as a whole, so that the abutting parts 41 on the left and right sides of the contact seat 4 abut against the two buckles 21 of the air switch 2, and the fixing bolt 5 is rotated so that the contact seat 4 is tightly fitted on the front side of the movable slide plate 3. At this time, the contact seat 4 can prevent the buckle 21 of the air switch 2 from moving downward and falling off, and the movable slide plate 3 and the fixed slider 6 are in close contact with the electrical cabinet or the wall, increasing the resistance and preventing it from moving easily.

[0030] By arranging a movable slide plate 3 on the mounting frame 1, and arranging a contact seat 4 that moves up and down on the movable slide plate 3, after the air switch 2 is fixed on the mounting frame 1, the contact seat 4 can limit the buckle 21 thereof, so that it cannot move downward, thereby preventing it from falling loose, thereby improving stability;

[0031] By providing an abutment portion 41 on the contact seat 4, the upper middle position of the contact seat 4 is engaged between the two buckles 21, so that it is connected to the movable slide 3 as a whole, and the movable slide 3 is in close contact with the electrical cabinet or the wall, which increases the resistance and prevents it from moving easily.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
