Description

Technical Field

[0001] The utility model belongs to the technical field of metal detectors, and in particular relates to a telescopic and foldable integrated structure of a metal detector. Background Art

[0002] Metal detectors are widely used and are divided into three main categories: electromagnetic induction, X-ray detection, and microwave detection. They are electronic instruments used to detect metals and can be applied in many fields. In engineering, they can be used to detect underground metal buried objects, such as pipes and pipelines. However, the existing technology has the following shortcomings when used:

[0003] The vertical pole on the metal detector often only has a single telescopic function or folding function, and cannot combine the telescopic and folding functions. When the entire device needs to be carried, after the single telescopic or folding is completed, the overall volume of the device is still large, which is inconvenient for actual transportation and carrying, and will take up more space. Summary of the Invention

[0004] The utility model addresses the problem that the upright pole of the metal detector in the prior art often only has a single telescopic function or a folding function, and cannot combine the telescopic and folding functions. When the device needs to be carried as a whole, after the single telescopic or folding is completed, the volume of the device as a whole is still large, which is inconvenient for actual transportation and carrying and will take up a lot of space. The following technical solutions are proposed:

[0006] As a preferred embodiment of the above technical solution, a butterfly-shaped piece is slidingly sleeved on the second sleeve, and a protective pad is installed on the butterfly-shaped piece.

[0007] As a preferred embodiment of the above technical solution, the butterfly-shaped member is fixedly connected with symmetrically distributed connecting plates, a connecting shaft is fixedly connected between the two connecting plates, a mounting plate is rotatably sleeved on the connecting shaft, a positioning block is fixedly connected to the mounting plate, a through hole is opened on the butterfly-shaped member, the positioning block is located in the through hole, and the positioning block is in contact with the outer surface of the second sleeve, and the length of the mounting plate is slightly larger than the distance between the two connecting plates.

[0008] As a preferred embodiment of the above technical solution, a wire is connected between the control box and the detection head.

[0011] The beneficial effects of the utility model are:

[0012] (1) The staff rotates the first mounting ring, and through cooperation with the first threaded ring, the first mounting ring gradually moves upward during the rotation. When the first mounting ring moves up to a certain position, it will be out of contact with the multiple first arc-shaped protrusions, and the force on the first arc-shaped protrusions disappears, so that the first arc-shaped positioning piece can produce a small deformation outward, so that the multiple first arc-shaped positioning pieces are out of contact with the outer surface of the first connecting rod, so that the second sleeve can be pulled downward. Similarly, the second mounting ring is rotated to move upward during the rotation. When the second mounting ring moves up to a certain position, it will be out of contact with the multiple second arc-shaped protrusions. When the folding mechanism is in place, the first and second locating pins are pulled out of engagement with each other, and the folding mechanism is moved out of engagement with the first and second locating pins, thereby folding the first and second locating pins.

[0013] (2) Rotate the mounting plate to disengage the positioning block from the outer surface of the second sleeve, then pull the butterfly piece to a suitable position, and then rotate the mounting plate in the opposite direction so that the mounting plate is located between the two connecting plates. The mounting plate fits tightly against the two connecting plates. At this time, the positioning block fits tightly against the outer surface of the second sleeve. The butterfly piece is positioned by the force exerted by the positioning block on the second sleeve. When the operator holds the handle, the arm can fit against the pad to ensure the comfort of the arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The staff rotates the first mounting ring 11, and through cooperation with the first threaded ring 10, the first mounting ring 11 gradually moves upward during rotation. When the first mounting ring 11 moves up to a certain position, it will disengage from the multiple first arc-shaped protrusions 13, and the force on the first arc-shaped protrusions 13 disappears, so that the first arc-shaped positioning piece 12 can produce a small deformation outward, so that the multiple first arc-shaped positioning pieces 12 are disengaged from the outer surface of the first connecting rod 2, so that the second sleeve 6 can be pulled downward. Similarly, the second mounting ring 15 is rotated to move upward during rotation. When the second mounting ring 15 moves up to a certain position, it will disengage from the multiple second arc-shaped protrusions 17. When the first sleeve 3 is disengaged from the first locating pin 18 and the second locating pin 19, the first sleeve 3 can be moved downwards. At the same time, the first butterfly nut 20 and the second butterfly nut 21 are rotated to disengage the first butterfly nut 20 and the second butterfly nut 21 from the first positioning pin 18 and the second positioning pin 19 respectively, and then the first positioning pin 18 and the second positioning pin 19 are pulled outwards, so that the first connecting rod 2 and the first sleeve 3 can be rotated to realize the folding function, thereby greatly reducing the volume occupied by the equipment and facilitating transportation and carrying.

[0028] like Figure 1 and Figure 2 As shown, a butterfly piece 22 is slidably sleeved on the second sleeve 6 , and a protective pad 23 is installed on the butterfly piece 22 .

[0029] When the operator holds the handle 7, the arm will contact the pad 23 to ensure the comfort of the arm.

[0031] Rotate the mounting piece 26 to disengage the positioning block 27 from the outer surface of the second sleeve 6, then pull the butterfly piece 22 to a suitable position, and then rotate the mounting piece 26 in the opposite direction so that the mounting piece 26 is located between the two connecting pieces 24. The mounting piece 26 fits tightly against the two connecting pieces 24. At this time, the positioning block 27 fits tightly against the outer surface of the second sleeve 6. The butterfly piece 22 is positioned by the force exerted by the positioning block 27 on the second sleeve 6, which makes it easy to adjust the position of the butterfly piece 22 according to different operators.

[0032] like Figure 2 and Figure 3 As shown, a wire 29 is connected between the control box 9 and the detection head 5 .

[0033] The control box 9 supplies power to the detection head 5 via the wire 29 , facilitating the subsequent use of the detection head 5 .

[0034] like Figure 1 As shown, a sealing cover 30 is provided on the protective box 8.

[0035] The protection box 8 and the sealing cover 30 are used in conjunction with each other to achieve waterproofing of the control box 9 .

[0036] like Figure 1 and Figure 3 As shown, a waterproof cover 31 is installed on the detection head 5.

[0037] The waterproof cover 31 is provided to make the probe head 5 waterproof.
