Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

As shown in fig. 1-3, the utility model relates to a hand-held type metal detector with function is reminded in outage, including casing 1 and the handle 2 of installing on casing 1, casing 1 internally mounted has metal detection part and power supply 11, metal detection part and power supply 11 are the conventional part among the prior art. A cavity 3 is formed in the handle 2, and the cavity 3 is a space extending in the vertical direction. The movable rod 4 is movably arranged in the cavity 3 up and down, and particularly, the outer surface of the movable rod 4 is matched with the inner wall of the cavity 3 so as to be capable of sliding up and down. An iron block 5 is arranged at the upper end of the movable rod 4, an electromagnet 6 is arranged above the iron block 5, and the electromagnet 6 is fixedly connected with the inside of the cavity 3. The electromagnet 6 is electrically connected with a power supply 11. A first return spring 81 for pushing the moving rod 4 to move downwards is connected between the moving rod 4 and the handle 2, and a guide passage (not shown) communicated with the cavity 3 is processed on the outer surface of the handle 2. According to actual needs, two guide channels can be oppositely arranged on the left and the right. And a top rod 7 is movably arranged in the guide channel from left to right. The outer surface of the mandril 7 is adapted to the inner wall of the guide channel so as to slide left and right. The end surface of the ejector rod 7 close to the moving rod 4 is processed with an inclined surface. The side of the moving rod 4 is provided with a wedge block 42 corresponding to the inclined surface. The wedge surface of the wedge block 42 is connected with the inclined surface in a sliding fit mode. A second return spring 71 which can push the mandril 7 to approach the moving rod 4 is connected between the mandril 7 and the handle 2. Through the structural design, when the power supply 11 is electrified, the electromagnet 6 attracts the iron block 5, so as to drive the movable rod 4 to move upwards, and then the ejector rod 7 moves towards the cavity 3 and contracts into the guide channel under the action of the second return spring 71. When the power supply 11 is cut off, the electromagnet 6 is separated from the iron block 5, the first spring 81 pushes the movable rod 4 to move downwards, the wedge block 42 synchronously moves downwards, and the ejector rod 7 is ejected outwards through the matching of the inclined plane.

The specific installation mode of the first return spring 81 is that the cover plate 41 is installed below the handle 2, the lower end of the moving rod 4 movably extends out of the handle 2 and is connected with the cover plate 41, the groove 8 is installed on the bottom surface of the handle 2, the cover plate 41 can be covered on the groove 8, the first return spring 81 is installed in the groove 8, one end of the first return spring 81 is connected with the cover plate 41, and the other end of the first return spring is connected with the bottom wall of the groove 8. In addition, in order to prevent the cover plate 41 from separating from the handle 2, a pulling rope 82 is installed in the groove 8, one end of the pulling rope 82 is connected with the cover plate 41, and the other end is connected with the bottom wall of the groove 8. Through the structural design, when the electromagnet 6 attracts the iron block 5, the cover plate 41 can be attached to the bottom of the handle 2 and seal the groove 8, so that the overall structure is more compact.

The second return spring 71 is specifically mounted by machining a sinking groove at the end through which the guide passes, mounting a moving plate 72 in the sinking groove, slidably connecting two ends of the moving plate 72 with the inner wall of the sinking groove, fixedly connecting the moving plate 72 with the ejector 7, and connecting one end of the second return spring 71 with the moving plate 72 and the other end with the inner wall of the sinking groove.

In order to improve the safety of the whole device, the end surface of the ejector rod 7 far away from the movable rod 4 is processed into an arc surface. Furthermore, the handle 2 and the housing 1 are made of an electrically insulating material. A switch button for switching the power supply 11 is mounted on the housing 2.

The working principle is as follows: when the metal detector is used, a worker holds the handle by hand and presses the switch button 9, the metal detector is electrified to start working, the electromagnet 6 attracts the iron block 5 and drives the moving rod 4 to move upwards, and the ejector rod 7 moves towards the cavity 3 and contracts into the guide channel under the action of the second return spring 71. When the power failure condition occurs in the using process, the electromagnet 6 is separated from the iron block 5, the first spring 81 pushes the movable rod 4 to move downwards, the wedge block 42 synchronously moves downwards, and the ejector rod 7 is ejected outwards through the matching of the inclined surface. The tip extrusion operating personnel's of ejector pin 7 hand, the detector outage condition can be judged through the sense of touch of hand to operating personnel, and then can in time remind operating personnel to take precautions against. In addition, the cover plate 41 can be separated from the handle 2, and a worker can observe the power failure condition of the metal detector more clearly.

This embodiment can in time remind operating personnel to take precautions against hand-held type metal detector outage situation, avoids the emergence of lou examining, effectively improves work quality.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
