Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4The embodiment of the utility model provides a portable radiation dose rate meter, comprising: a radiation measuring instrument body 1 for performing radiation environment and radiation protection detection, a handle 2 for conveniently holding the radiation measuring instrument body 1, and a connecting component 3 for connecting the radiation measuring instrument body 1 and the handle 2 and adjusting the angle of the handle 2, the handle 2 is movably connected to the bottom of the radiation measuring instrument body 1 through the connecting component 3; the connecting component 3 comprises a supporting member 31 arranged on the radiation measuring instrument body 1, a rotating member 32 is arranged between the bottom of the supporting member 31 and the top of the handle 2, a positioning member 33 for locking the rotating member 32 is arranged on the supporting member 31, and a guide member 34 for guiding a local part of the positioning member 33 is arranged on the rotating member 32.

[0026] Among them, the radiation measuring instrument body 1 includes a main body shell 11, and a telescopic cylinder 12 is installed in the inner cavity of the main body shell 11. The telescopic rod of the telescopic cylinder 12 penetrates to the outside of the main body shell 11 and is fixedly connected to a detector 13. The handle 2 is located below the main body shell 11. By starting the telescopic cylinder 12, the telescopic rod of the telescopic cylinder 12 can drive the detector 13 to move along the axial direction of the telescopic rod, so as to extend the detector 13 into a narrow area or a blind spot in the room for detection.

[0027] Among them, the support member 31 includes a ring 311 fixedly sleeved on the surface of the main body shell 11, and the bottom of the ring 311 is fixedly connected to two symmetrical lugs 312, and the top of the handle 2 is located between the two lugs 312. The support member 31 can provide a supporting basis for the rotating member 32 and the positioning member 33.

[0028] Among them, the rotating member 32 includes a rotating rod 321 that passes through and is fixedly connected to the top of the handle 2. A through hole 322 is opened on the lug 312. The inner wall surface of the through hole 322 and the rotating rod 321 are rotatably connected through a rotating shaft. By rotating the handle 2, the handle 2 can drive the rotating rod 321 to rotate with the rotating shaft as the center, thereby realizing the holding angle adjustment of the handle 2 and the folding storage effect.

[0029] Among them, the positioning member 33 includes a retaining ring 331 fixedly connected to the outer side of one of the lugs 312, and a positioning hole 332 is opened on the retaining ring 331. One end of the rotating rod 321 is movably connected to a positioning block 333 that can be clamped into the inner cavity of the positioning hole 332 through a guide member 34. The cross-sectional surfaces of the positioning hole 332 and the positioning block 333 are both regular octagons. A baffle 334 is fixedly connected to one side of the positioning block 333. By clamping the positioning block 333 into the inner cavity of the positioning hole 332, the rotating rod 321 can be locked, so that the handle 2 can be stably maintained in a certain state.

[0030] Among them, the baffle 334 is an iron baffle, and the baffle ring 331 is a magnetic baffle ring. The baffle 334 is adsorbed on one side of the baffle ring 331 by magnetic force, and the magnetic force is used to maintain the stability of the connection between the baffle 334 and the baffle ring 331, which effectively avoids the baffle 334 from accidentally separating from the baffle ring 331 during use, thereby improving the stability of the handle 2.

[0031] A protrusion 3341 is integrally formed on one side of the baffle 334 away from the retaining ring 331 . The protrusion 3341 can increase the contact area between the finger and the baffle 334 , making it easier to pull or rotate the baffle 334 .

[0033] The center lines of the rotating rod 321 , the through hole 322 , the retaining ring 331 , the positioning hole 332 , the positioning block 333 , the retaining plate 334 , the guide groove 341 and the guide column 342 are on the same straight line.

[0034] The working principle of the utility model is: the baffle plate 334 is pulled forcefully by the protrusion 3341, the baffle plate 334 drives the positioning block 333, the positioning block 333 drives the guide column 342 to slide in the inner cavity of the guide groove 341, the guide column 342 drives the sliding hole 343 to move, so that the slider 344 slides in the inner cavity of the sliding hole 343 until the guide column 342 moves to the maximum limit, at which time the positioning block 333 is separated from the inner cavity of the baffle ring 331, thereby completing the unlocking operation of the rotating rod 321; then the baffle plate 334 is rotated, so that the baffle plate 334 drives the positioning block 333, the guide column 342, the sliding hole 343, the slider 344, the rotating rod 321 and the handle 2 rotates synchronously, so that the handle 2 rotates with the rotation axis between the rotating rod 321 and the through hole 322 as the center of the circle. When the baffle plate 334 rotates 90° clockwise, the handle 2 is in a horizontal state, thereby realizing the folding and storage operation of the handle 2; when the baffle plate 334 rotates 45° clockwise or 45° or 90° counterclockwise, the handle 2 is in an inclined state or a horizontal state, thereby realizing the adjustment of the holding angle of the handle 2, so that the handle 2 is suitable for different holding requirements; finally, the baffle plate 334 is slowly released, so that the baffle plate 334 is adsorbed on the baffle ring 331 again through the magnetic force, and the positioning block 333 is stuck to the inner cavity of the positioning hole 332.
