Description

  The present invention relates to a fixture for a surveillance camera provided in a suspended surveillance camera housing.

  In recent years, an increasing number of surveillance cameras installed in buildings or street corners can be housed in a hanging housing having a dome-shaped cover. There are many general-purpose housings that can be applied to a plurality of types of surveillance cameras.

By the way, in the suspension type surveillance camera housing, if the imaging position of the camera is raised, the upper part of the dome-shaped cover is also photographed, and as a result, the upper part of the photographing screen is cut off. In order to avoid this, it is necessary to replace the fixing bracket for each camera to be mounted and adjust the position of the camera to be sufficiently lower. However, it is troublesome to prepare a bracket for each camera, and it may not be possible to deal with new products and overseas products immediately.
In view of such a problem, an object of the present invention is to make it possible to adjust the vertical mounting position of a surveillance camera provided in a suspension type surveillance camera housing without exchanging the mounting bracket. .

In order to solve the above problems, the present invention has the following configuration.
According to the first aspect of the present invention, the cover in the housing is used as a surveillance camera fixing tool for fixing a surveillance camera to be used so as to be suspended from above in a housing having a transparent dome-shaped cover below. A through hole or a female screw formed by a plate body that is mounted substantially horizontally at a position higher than the upper edge of the housing, and having a nut fixed at a position that is substantially the center of the housing when mounted on the housing. A fixing plate provided with a hole and a plate body provided with an engaging portion for fixing the surveillance camera on the lower surface, and a bolt engaging the bolt or the female screw at the approximate center of the upper surface on the plate surface And a moving plate provided substantially vertically.

In the surveillance camera fixture according to claim 2, a nut is fixed to the fixing plate, and the nut is divided into two or more pieces symmetrically with respect to the center line and at a lower position. A base having a mortar-shaped upper surface is provided, and each piece is pressed downward by an elastic body against the base, and when the bolt is pushed upward against the nut, the piece resists the elastic body. The bolts can be passed freely by opening and moving upward, and when lowering the bolts, the pieces are moved closer to each other by the mortar-shaped base so that they can be engaged with each other and moved unless the bolts are rotated along the female threads. It has a structure that regulates so that it cannot be done.
The device according to claim 3, wherein the upper end of the surveillance camera fixture is fixed to the fixed plate, and the lower end of the wire is fixed to the movable plate so that the lower end can be fixed and separated. It has the wire which is done.

With the configuration as described above, the present invention has the following effects.
According to the first aspect of the present invention, when the bolt on the upper surface of the moving plate is engaged with the nut or the female screw of the fixed plate and the moving plate is rotated around the bolt, the bolt moves up and down with respect to the net or the female screw. It will be. That is, since the vertical distance of the moving plate relative to the fixed plate can be arbitrarily adjusted, the height of the monitoring camera fixed to the lower surface of the moving plate can also be arbitrarily adjusted.
According to the second aspect of the present invention, since the bolt of the moving plate can be moved upward only by pushing it up without being rotated, the position adjustment of the moving plate can be performed more easily.
According to the third aspect of the present invention, when the moving plate is rotated, the wire is separated from the moving plate, and the wire is firmly fixed to the moving plate when the position of the moving plate is determined. Therefore, it is possible to restrict the rotation of the moving plate and to prevent the vertical position of the camera from shifting due to vibration or the like.

It is a disassembled perspective view which shows the surveillance camera fixture. It is an enlarged vertical view in the nut part of a fixed plate. It is a perspective view which shows the example of the housing which mounts the surveillance camera fixing tool. It is a longitudinal cross-sectional view of the housing which attached the surveillance camera fixing tool. (A) is a longitudinal cross-sectional view of the housing which attached the monitoring camera fixture which shows the state which moved the moving plate upwards, (b) is a monitoring camera fixture which shows the state which moved the moving plate below. It is a longitudinal cross-sectional view of the mounted housing.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an exploded perspective view of the surveillance camera fixture X according to the embodiment. The surveillance camera fixture X has a fixed plate 10, a moving plate 20, and a fixed wire portion 30.
The fixing plate 10 is a rectangular plate, provided with through holes 11 and 11 for fixing on the left and right, a through hole (not shown) in the center, and a nut 12 welded and fixed to the upper surface side of the through hole. ing. As the nut 12, a one-way type one-touch nut (trademark) manufactured and sold by Nippon Hojo Co., Ltd. is used. FIG. 2 shows a partially enlarged longitudinal sectional view of the fixing plate 10 near the nut 11. The nut 12 has an internal thread formed therein and a cylindrical body having a taper formed on the outer periphery of the lower portion, a piece 12a that is symmetrically divided about the center line, a mortar-shaped base 12b that supports the lower part of the piece 12a, And a spring 12c for pressing the upper surface of 12a downward. With such a configuration, normally, the piece 12a pressed downward by the spring 12c is contracted inward by the inclination of the base 12b and functions as a nut. Here, when the bolt 21 is engaged with the nut 12 and the bolt 12 is pushed upward, the piece 12a is pushed upward against the spring 12c. As a result, the restriction of the piece 12a by the base 12b becomes loose, and the bolt 21 Since each piece 12a is pushed and moved outward, the bolt 21 can be moved upward without being constrained by the piece 12a without being rotated. On the other hand, when the bolt 21 is pulled downward, the piece 12a is pressed against the base 12b and the piece 12a is pushed inward by the inclination of the base 12b, so that the female screw of the piece 12a engages with the bolt 21 and the bolt 21 rotates. Cannot move down without it. However, since the female screw is formed, it can be moved downward by rotating the bolt 21.

The moving plate 20 is composed of a cross-shaped plate body, and a pair of opposing two sides is rounded. A bolt 21 is vertically fixed at the center of the upper surface of the moving plate. In addition, a camera fixing hole 22 that is a through hole for fixing the surveillance camera, a handle hole 23 including two slightly larger through holes for inserting a finger, and a fixing wire 30 are passed through the plate surface of the moving plate 20. A wire fixing hole 24 which is a through hole is provided.
The fixed wire portion 30 is a frustoconical wire fixture made of a metal wire 31 with a plate 31 forming a ring 31a fixed on the upper end side, and a rubber having a hole formed on the lower end side of the wire 31. 32. The upper end side of the wire fixture 32 is slightly smaller than the inner diameter of the wire fixing hole 24 of the moving plate 20, and the lower end side is formed larger than the inner diameter of the wire fixing hole 24.

A method of using the surveillance camera fixture X having the above configuration will be described. FIG. 3 shows a perspective view of the housing H in which the surveillance camera fixture X is mounted. The housing H has a main body H2 that is suspended and fixed to a bracket H3 that is fixed to a wall surface or the like, and a transparent hemispherical cover H3 is provided at the lower end of the main body H2. The surveillance camera is fixed in the main body H2 and images the outside from the cover H3. FIG. 4 is a longitudinal sectional view of the monitoring camera fixture X in which the monitoring camera C is fixed in the housing H.
The fixing plate 10 is fixed in the housing body H1 by screws through the through holes 11 and 11 below the circuit board P provided with a hole Pa in the center for controlling the surveillance camera. The fixing plate 10 is fixed at a certain distance from the circuit board by a spacer. Further, the ring 31a of the wire 31 is nipped and fixed between the upper surface of the through hole 11 on one side and the spacer in a state where a screw is passed. The lower end side of the wire 31 is fixed to the inner wall of the housing body H2 with an adhesive tape so as not to interfere with the movement of the moving plate 20 described later.

  The moving plate 20 is fixed to the fixed plate 10 by engaging the bolts 21 with the nuts 12 of the fixed plate 10. Note that a metal fitting for fixing the monitoring camera C is fixed to the moving plate 20 through the camera fixing hole 22 as necessary. It is necessary to adjust the distance between the moving plate 20 and the moving plate 20 according to the size of the monitoring camera C to be mounted. At this time, since the moving plate 20 can move without rotating upward as described above, the bolt 21 is first inserted into the nut 12 and pushed up to an appropriate position, and a finger is inserted into the handle hole 23 from this position. By rotating the moving plate 20, the bolt 21 is moved with respect to the nut 12, and the position is finely adjusted. When the position adjustment of the moving plate 20 is completed, the adhesive tape on the lower end side of the wire 31 is peeled off and passed from the top to the bottom through the wire fixing hole 24 of the moving plate 20 that is closest to directly below the upper end of the wire 31. And it pushes up upwards from the lower end of the wire 31 through the wire fixing tool 32, and the wire fixing tool 32 is inserted and fixed in the wire fixing hole 24 which let the wire 31 pass. Thereafter, the wire 31 is pulled tightly at the lower end. The monitoring camera 20 is fixed to the lower surface of the moving plate 20 with the position of the moving plate 20 determined.

As described above, the monitoring camera fixture X according to the present embodiment can adjust the height at the position where the bolt 21 is fixed to the nut 12. For the monitoring camera Ca having a height, FIG. As shown in FIG. 5B, the moving plate 20 is moved upward, and for the monitoring camera Cb that is not so high, the moving plate 20 is moved downward as shown in FIG. The lens position of the camera can be adjusted to a position close to the cover H2. That is, it is possible to align the lens with respect to various monitoring cameras so that the lens position is appropriate.
Some surveillance cameras drive panning, tilting, and the like. However, since the moving plate 20 is fixed by the fixed wire 30, the moving plate 20 is rotated by the vibration caused by the operation of the monitoring camera, and the height is increased. It is suppressed that a position shifts.

In the above embodiment, the one-touch nut (trademark) is used as the nut 11 to be fixed to the fixing plate 10, but a general nut may be used, and instead of providing the nut 11, a central through-hole is used. You may make it engage with the volt | bolt 21 by cutting a female screw in a hole.
Moreover, in the said embodiment, although the wire 31 is fixed to the wire fixing hole 24 of the movement plate 20, the notch which the wire 31 fits tightly in the outer periphery of the movement plate 20 is formed, and the wire 31 is formed in this. You may make it fix by fitting a lower end. Further, instead of using the wire 31, the moving plate 20 may be fixed by sandwiching inclusions such as rubber between the outer peripheral edge of the moving plate 20 and the inner wall of the housing body.
