Description

Technical Field

[0001] The utility model relates to the technical field of access control systems and fire-fighting equipment, and in particular to a bracket for installing a magnetic lock and a sequencer. Background Art

[0002] In the application scenario of fire-fighting double doors, in order to ensure that the door leaves are closed in place in an emergency and block smoke and fire, a sequencer (also called a door closing sequencer) needs to be installed to control the closing order of the door leaves. The sequencer is installed at the top of the door frame. In the access control system, the magnetic lock is also installed at the top of the door frame. Therefore, the installation position of the magnetic lock conflicts with the installation device of the sequencer. The magnetic lock and the sequencer cannot be installed on the same door frame, and the requirements of access control and door closing sequence cannot be met at the same time.

[0003] After searching, it was found that in the patent with announcement number CN213144326U, "Fusion bracket device for magnetic lock and sequencer" was disclosed, see Figure 1 The patent includes a bracket body 1, which is a rectangular shell structure. Two adjacent long side openings on the bracket body 1 constitute a magnetic lock installation opening 11 and a magnetic lock working opening 12. Ears 13 are provided on both sides of the magnetic lock installation opening 11 on the bracket body 1, and bracket fixing screw holes are provided on the ears 13. A sequencer installation screw hole is provided on the end face of the bracket body 1 corresponding to the magnetic lock installation opening 11.

[0004] When the above patent is in use, the magnetic lock is fixedly installed on the top of the door frame, the bracket body covers the outside of the magnetic lock, the ears are fixed on the top of the door frame, and the sequencer is installed on the outside bottom of the bracket body, which can meet the installation requirements of the magnetic lock and the sequencer at the same time.

[0005] At present, double door magnetic locks have the following specifications: length 32.6cm × thickness 2.2cm × height 4.0cm, length 33.6cm × thickness 2.1cm × height 3.8cm, length 49.2cm × thickness 2.9cm × height 5.6cm, length 50.0cm × thickness 2.6cm × height 4.9cm, length 56.4cm × thickness 3.9cm × height 7.2cm, etc. In the above specifications, the length from 32.6cm to 56.4cm has a difference of tens of centimeters, and the height from 3.8cm to 7.2cm also has a difference of several centimeters.

[0006] However, since the bracket body is a rectangular shell structure, the length space and height space of the bracket body are limited, and it is difficult to accommodate a magnetic lock with a longer length and a higher height, which reduces the flexibility of use. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides a bracket for installing a magnetic lock and a sequencer. The utility model can adapt to magnetic locks of different lengths and heights, thereby improving the flexibility of use.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A bracket for installing a magnetic lock and a sequencer comprises a bracket body, the bracket body comprises a vertical plate, the upper part of the vertical plate is provided with a bracket fixing screw hole, the middle part of the vertical plate is provided with an adjustment hole, the adjustment hole comprises a plurality of first transverse holes distributed in the vertical direction, one side of the first transverse hole is provided with a first vertical hole extending upward, the first vertical hole is provided with a second transverse hole on the side away from the first transverse hole, all the second transverse holes are connected through the second vertical holes, the bracket body also comprises a transverse plate, the transverse plate is provided with a sequencer mounting screw hole, the transverse plate is provided with a support rod, the upper part of the support rod is provided with an adjustment rod, and the adjustment rod cooperates with the adjustment hole.

[0010] Furthermore, the cross section of the adjusting rod is a regular quadrilateral.

[0011] Furthermore, anti-slip grooves are provided on the hole wall of the first transverse hole.

[0012] Furthermore, the adjusting rod is provided with a limit block at the end surface facing away from the supporting rod.

[0013] Furthermore, the adjusting rod is provided with a limiting screw hole on the end face facing away from the supporting rod, and the limiting block adopts a limiting screw, which cooperates with the limiting screw hole.

[0014] Furthermore, the corners of the vertical plate and the corners of the horizontal plate are both rounded.

[0015] The utility model has the beneficial effects:

[0016] 1. In the present invention, because both sides of the long sides of the vertical plate and both sides of the long sides of the horizontal plate are open, the space in the length direction is not limited, and a longer magnetic lock can be accommodated. Because the height of the horizontal plate is adjustable, the thicker the height of the magnetic lock, the lower the height of the adjustment rod can be adjusted to the first horizontal hole, so that the height space above the horizontal plate can accommodate a higher magnetic lock. In short, the present invention can adapt to magnetic locks of different lengths and heights, and improves the flexibility of use.

[0017] 2. When the height of the magnetic lock is small, the height of the horizontal plate can be increased, so that the height of the sequencer located at the bottom of the horizontal plate can be adjusted to make the overall structure more compact, avoid being hit by tall passers-by, and improve safety in use.

[0018] 3. When adjusting the height of the horizontal plate, the operation is simple. The installer slides the adjustment rod in the adjustment hole to adjust the adjustment rod to the first horizontal hole of the adjustment hole with a suitable height. In addition, the setting of the first vertical hole in the adjustment hole can prevent the adjustment rod from sliding directly from the current first horizontal hole into the first vertical hole, which can improve the stability of the adjustment rod in the current first horizontal hole.

[0019] 4. By providing anti-slip grooves in the first transverse hole, the friction resistance of the adjusting rod in the first transverse hole can be increased, and the stability of the adjusting rod in the current first transverse hole can be further improved.

[0020] 5. The setting of the limit block can prevent the adjusting rod from being pulled out of the adjusting hole from the rear side of the vertical plate, thereby improving the reliability of the entire bracket.

[0021] 6. By using the limit screw as a limit block and matching the limit screw with the limit screw hole on the adjusting rod, the limit screw can be easily disassembled and assembled. After the limit screw is removed, the vertical plate and the horizontal plate can be easily disassembled, so that the vertical plate and the horizontal plate can be replaced separately without being discarded as a whole, which can save maintenance costs.

[0022] 7. The rounded corners on the vertical and horizontal boards can prevent the corners of the vertical and horizontal boards from scratching the installers, thus improving the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example:

[0041] See also Figures 2 to 7 A bracket for installing a magnetic lock and a sequencer comprises a bracket body. The bracket body comprises a vertical plate 4 and a horizontal plate 5.

[0042] See also Figures 2 to 6 The upper part of the vertical plate 4 is provided with a bracket fixing screw hole 131. The middle part of the vertical plate 4 is provided with an adjustment hole. The adjustment hole includes a plurality of first transverse holes 41 distributed in the vertical direction, one side of the first transverse hole 41 is provided with a first vertical hole 42 extending upward, the first vertical hole 42 is provided with a second transverse hole 43 on the side away from the first transverse hole 41, and all the second transverse holes 43 are connected through the second vertical hole 44.

[0043] See also Figures 2 to 7 The bracket body also includes a horizontal plate 5, on which a sequencer mounting screw hole 14 is provided, and a support rod 51 is fixedly installed on the horizontal plate 5. An adjustment rod 52 is fixedly installed on the upper part of the support rod 51, and the adjustment rod 52 is used to cooperate with the adjustment hole. The cross section of the adjustment rod 52 is a regular quadrilateral, and the regular quadrilateral is a square or a rectangle.

[0044] The hole wall of the first transverse hole 41 is provided with anti-slip grooves (not shown in the figure).

[0045] The adjusting rod 52 is provided with a stopper at the end surface facing away from the supporting rod 51, and the vertical plate 4 is located between the stopper and the adjusting rod 52. Figure 6 and Figure 7 The adjusting rod 52 is provided with a limiting screw hole 53 on the end surface away from the supporting rod 51; Figure 2 and Figure 4 The limiting block adopts a limiting screw 54, and the limiting screw 54 cooperates with the limiting screw hole 53.

[0046] See also Figures 2 to 6 The corners of the vertical plate 4 and the corners of the horizontal plate 5 are both provided with rounded corners 6.

[0047] See also Figure 8 , the method of using this embodiment is:

[0048] (1) Adjust the height of the horizontal plate 5. Specifically, place the magnetic lock 2 on the top surface of the horizontal plate 5, and then slide the adjustment rod 52 through the current first horizontal hole 41, the first vertical hole 42, and the second horizontal hole 43 into the second vertical hole 44. According to the current height of the magnetic lock 2, slide the adjustment rod 52 through the second vertical hole 44, the second horizontal hole 43, and the first vertical hole 42 into the first horizontal hole 41 of the corresponding height. At this time, the top surface of the magnetic lock 2 is lower than the height of the bracket fixing screw hole 131, indicating that the current height of the space above the horizontal plate 5 is sufficient to accommodate the current height of the magnetic lock 2.

[0049] The thicker the magnetic lock 2 is, the adjustment rod 52 needs to be adjusted to a lower first transverse hole 41 so that the current height of the space above the transverse plate 5 is sufficient to accommodate the current height of the magnetic lock 2 .

[0050] (2) Remove the magnetic lock 2 from the top surface of the horizontal plate 5 and fix the magnetic lock 2 on the bottom surface of the door frame top 7.

[0051] (3) The sequencer 3 is fixed to the bottom surface of the horizontal plate 5 by means of the sequencer mounting screw holes 14 and the matching bolts.

[0052] (4) The vertical plate 4 is fixed to the side of the door frame top 7 through the bracket fixing screw hole 131 and the self-tapping screw. At this time, the vertical plate 4 is located at the rear side of the magnetic lock 2 and does not block the working surface of the magnetic lock 2.

[0053] In this embodiment, because both sides of the long sides of the vertical plate 4 and both sides of the long sides of the horizontal plate 5 are open, the space in the length direction is not limited, and a longer magnetic lock 2 can be accommodated. Because the height of the horizontal plate 5 is adjustable, the thicker the height of the magnetic lock 2 is, the adjustment rod 52 can be adjusted to the first horizontal hole 41 with a lower height, so that the height space above the horizontal plate 5 can accommodate a higher magnetic lock 2. In short, this embodiment can adapt to magnetic locks 2 of different lengths and heights, and improves the flexibility of use.

[0054] When the height of the magnetic lock 2 is relatively small, the height of the horizontal plate 5 can be increased, thereby adjusting the height of the sequencer 3 located at the bottom of the horizontal plate 5, making the overall structure more compact, avoiding being hit by tall passers-by, and improving safety in use.

[0055] When adjusting the height of the horizontal plate 5, the operation is simple and convenient. The installer slides the adjustment rod 52 in the adjustment hole to adjust the adjustment rod 52 to the first horizontal hole 41 of the adjustment hole with a suitable height. In addition, the provision of the first vertical hole 42 in the adjustment hole can prevent the adjustment rod 52 from directly sliding from the current first horizontal hole 41 into the first vertical hole 42, and can improve the stability of the adjustment rod 52 in the current first horizontal hole 41.

[0056] By providing anti-slip grooves in the first transverse hole 41 , the friction resistance of the adjustment rod 52 in the first transverse hole 41 can be increased, and the stability of the adjustment rod 52 in the current first transverse hole 41 can be further improved.

[0057] The setting of the limit block can prevent the adjustment rod 52 from being withdrawn from the adjustment hole from the rear side of the vertical plate 4, thereby improving the reliability of the entire bracket.

[0058] By using the limit screw 54 as a limit block and matching the limit screw 54 with the limit screw hole 53 on the adjusting rod 52, the limit screw 54 can be easily disassembled and assembled. After the limit screw 54 is removed, the vertical plate 4 and the horizontal plate 5 can be easily disassembled, and the vertical plate 4 and the horizontal plate 5 can be easily replaced separately without being discarded as a whole, thereby saving maintenance costs.

[0059] The rounded corners 6 on the edges of the vertical plate 4 and the horizontal plate 5 can prevent the edges of the vertical plate 4 and the horizontal plate 5 from scratching the installer, thereby improving the safety of use.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
