Description

Technical field to which this utility model belongs

This utility model refers to small (miniature) metal detectors of small size, which are called "pointer" or "dot pointer"; and is characterized in that it provides a structure between the search head and the housing component, allowing them to be detachably installed in each other and, therefore, the point metal detector of the present utility model has replaceable search heads.

Prior Art of the Present Utility Model

Miniature metal detectors, called pointers or point pointers, are used to indicate the exact location of targets underground for which relevant data has been detected. Known point detectors available in the prior art are one-piece metal detectors with a housing that is monolithic with a search head (usually made of plastic or a plastic-based material). Design patents named "Handheld Metal Detector" No. USD 459246 S1, "Handheld Metal Detector" No. USD 459245 S1, "Tactical Handheld Metal Detector" No. USD 513706 S1, "Tactical Handheld Metal Detector" No. USD 497559 S1 can be cited as examples available monolithic point metal detectors.

As you can see from the examples above, there are currently two types of point metal detectors.

The first type is a point metal detector with a rod-shaped search head. In the prior art, said search head is monolithic with a housing. This type of point metal detectors provides detection by digging the ground of the exact position of the target, the position of which was approximately detected by the long-range search heads in the form of a rod.

The second type is a point metal detector with a search head in the shape of a circle. Search with point metal detectors of this type is carried out by moving them over the ground (ground). The search head in the shape of a circle is not suitable for searching with excavation and works as a normal-sized metal detector such as a rod. However, its size is reduced to conduct a point search in a specific area. Users looking for a buried object need two types of point metal detectors in their search equipment.

Since the aforementioned spot detectors are of monolithic construction, users need to have both types of spot detectors in their equipment. Moreover, since the housings of point metal detectors have a monolithic structure with search heads, it is very difficult to repair the search head in the event of a breakdown. In this case, users need to buy new products.

Brief disclosure of this utility model

The subject of this utility model is a point metal detector in which a search head and a housing component are detachably inserted into each other and as a result the metal detector has replaceable search heads; and, accordingly, it eliminates the disadvantages of monolithic point metal detectors of the current state of the art;

Due to the design of the spot metal detector with an interchangeable search head with the same body, different types of search heads can be used. Thus, the user can, with one body, take advantage of both rod-type and round-type heads and other types of search heads. Thanks to this utility model, the user has a single housing device (metal detector) with two or more different functions.

Thanks to the point metal detector with replaceable search head, defective search heads and / or housing (signal processing electronics, assembly with parts for adjustment and holding knob by the user) can be repaired independently of each other. Moreover, defective and irreparable search heads or search heads, the repair of which is more expensive than replacing them, can be replaced with new ones that can be used with the old housing. This useful model simplifies the maintenance of the device and the purchase of spare parts.

All possible drawbacks of a detachable design (isolation of connections, transmission of electronic signals, connection stability, etc.) of a metal detector with a replaceable search head have been thought out and eliminated.

The device can also be used underwater thanks to the spacers and the way the search heads are fixed to the body. In particular, a round search head can be used in an underwater metal detector.

Disclosure of this utility model

The point metal detector of this utility model generally consists of a replaceable search head and housing (signal processing electronics, assembly with parts for adjustment and a handle for holding by the user). The housing can work with various types of search heads due to its split design.

The design of the housing and search heads allows them to be plugged into each other and disconnected. Moreover, the joints between the components are best protected from external influences thanks to this split design.

The spot metal detector of this invention has a handle component in the form of an extension to the rear of the antenna section of the search head. The specified handle component allows the search head to be mounted on the body. The specified handle component has at least one protrusion. In an ideal design, these protrusions are aligned along the handle component (with defined gaps between them). These protrusions can be located along one line or along two lines on either side of the handle. In another embodiment, there may be three or more lines of protrusions. Such lines of protrusions are located with gaps between them. At the end of the handle there is a connector section that connects the electronic circuits to the housing.

The housing has a cavity that allows the search head handle component to be inserted into it and seated within the housing. Since the handle component is generally cylindrical, the cavity in the body is also cylindrical. On the inner surface of the said cavity there are in-line slots corresponding to the lines of the protrusions on the handle. Said lines of pockets are located with gaps between them, which correspond to the gaps between the aforementioned lines of protrusions. The gaps between the same number of socket lines and protrusion lines prevent the protrusions and slots from snagging each other when the search head handle is inserted into the body cavity. The sockets located on the inner surface of the cavity and the projections on the surface of the head cling to each other according to the principle of rotation and fixation.

When the user wishes to connect a separate search head to the housing, he inserts the search head handle into the housing cavity. During this process, the search head or body is rotated axially by a small angle compared to its normal connected position. This allows the protrusions to pass into the gaps between the socket lines without clinging to them. When the handle component of the search head is fully inserted into the body cavity, the body or search head is rotated axially through a small angle to their connected position and the sockets within the body cavity can retain the search head protrusions. In other words, during this pivoting movement, the protrusions of the search head fall into the slots.

When the tabs are placed in the slots, the electronic circuit connector on the search head handle is connected to a connector receptacle at the end of the body cavity. As a result, the electronic circuits of the housing and the search head are connected. In an exemplary design, the sockets may be angled slightly towards said connector receptacle. In this case, the projections are inserted into the sloped slots, and the handle moves a little further into the cavity during the pivoting and locking operation. Therefore, this provides a more reliable connection between the connector and the connector receptacle.

There are gaskets in the area where the search head is connected to the body and in the area where the connector is connected to the connector receptacle. Due to this, when the search head is mounted on the body, the device can be used underwater without any problems.
