Description

Detector for detecting a target object

Technical Field

The utility model relates to the technical field of monitoring devices, in particular to a detector.

Background

An intrusion detector is widely used for security of office buildings, houses and the like as a device for monitoring intrusion behaviors in a specific space area. In order to meet the detection requirements of specific angles and ranges, the application of the detector is expanded, and the intrusion detector is matched with a bracket with an angle adjusting function.

At present, an angle adjusting bracket of the intrusion detector is generally a universal ball bracket, and the detection angle of the universal ball bracket is generally fixed through friction resistance generated by interference fit between a universal ball head and a ball cavity of a mounting seat. After the bracket and the detector are installed, a user can rotate the detector up and down and left and right by bare hands to adjust the detected direction. In order to facilitate rotation, the frictional resistance between the universal ball head and the ball cavity of the mounting seat cannot be designed to be too great. In the actual use process, an intruder can apply a certain torque external force to the detector to change the detection angle, so that intrusion detection is avoided. After long-time use, the bracket itself can sag due to natural gravity, stress relaxation of structural members and the like, so that the fixed angle is deviated. In order to make the angle fixing more firm, positioning teeth are added on part of the bracket at the rotary hinge, and the positioning teeth are kept engaged by locking the exposed bolts. However, the intruder can directly loosen the bolt to change the angle.

It can be seen that the angle adjusting bracket of the current intrusion detector is difficult to apply in high-level security occasions.

From the above structure, it can be known that:

the horizontal and pitching angle positioning of the detector is realized by the meshing of racks in the first damping part and the second damping part. Compared with the friction resistance positioning angle mode, the rack meshing positioning angle mode can ensure that the angle of the bracket cannot be changed under the action of external force. Meanwhile, after the locking screw is screwed down, the user closes the shell 100, at the moment, the locking screw is hidden inside the detector, the user can only touch the screw by opening the shell 100, and the detector has an opening alarm function, so that the detection direction can be prevented from being changed by illegally unscrewing the screw without adding an additional anti-disassembly switch.

The locking method of the detector comprises the following steps: the relief hole 24 on the rotor 20 and the second kidney-shaped hole 113 on the connecting portion 11 may be aligned at any horizontal angle within the design range, and the first kidney-shaped hole 33 on the bottom case 30 may be aligned at any pitch angle within the design range.

When the locking screw has not been tightened and there is sufficient clearance between the screw head and the bottom shell 30, the rotor 20 and the bottom shell 30 can be pulled forward, respectively, to disengage the horizontal pitch positioning teeth. The user can lock the angle by tightening the locking screw after rotating the rotator 20 and the bottom case 30 according to the requirements of the horizontal and pitching angles.

In the utility model, the bottom shell 30 and the mounting part 31 are integrally designed, compared with the conventional method that the mounting part 31 is rotationally connected with the bracket main body and then connected with the rear shell of the detector through the screw, the operation of connecting the bottom shell 30 and the mounting part 31 of the detector by a user is reduced, the number of parts is less, the structure is simpler, and the size is smaller.

As can be seen from the above description, the technical solution of the present utility model has at least the following technical effects:

(1) Compared with a universal ball support, the utility model has the advantages that the tooth meshing positioning is more accurate and firm, the angle is not easy to be changed by an intruder, the falling caused by stress relaxation, natural gravity and the like after long-time use is avoided, and the internal locking can prevent the intruder from directly contacting with the angle adjusting component, so that the utility model meets the specification of security and protection product standard (EN 50131-2-4).

(2) The utility model is provided with the first graduated scale and the second graduated scale, thereby being convenient for users to accurately adjust the angle and having good user experience. The meshing teeth in the vertical direction are integrated on the bottom shell of the detector, so that the number of user installation steps is reduced, the number of parts is fewer, the structure is simpler, and the size is smaller.

(3) The middle shaft of the detector is completely hidden in the detector, only two parts of the base and the rotator can be seen in appearance, and the detector is simpler and more attractive in whole.

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present utility model.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
