[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] The present invention will be further described below with reference to the accompanying drawings:
[0023] like Figure 1 - Figure 4 As shown, a steel rod puller for soil radon detection includes a locking ring body 100. Vertical sliding sleeves 200 are fixedly connected to the left and right sides of the locking ring body 100. A lever mechanism is symmetrically distributed on the outer side of the vertical sliding sleeves 200. The lever mechanism includes a connecting rod 301. One end of the connecting rod 301 is hinged to the vertical sliding sleeve 200, and the other end of the connecting rod 301 is hinged to a lever 302. A support column 303 is provided at the bottom of the lever 302. The top end of the support column 303 is hinged to the lever 302 near the connecting rod 301. A symmetrically distributed support mechanism is provided at the bottom of the support column 303. A locking mechanism is provided at the bottom of the locking ring body 100, and a base ring body 600 is provided at the bottom of the support mechanism.
[0024] The locking ring 100 is used to connect the locking mechanism, the vertical sliding sleeve 200 is used to connect the lever mechanism, and the support column 303 forms the fulcrum of the lever 302 under the support of the support mechanism. The distance between the fulcrum and the inner end of the lever 302 is less than the distance between the fulcrum and the outer end of the lever 302. Therefore, when the outer end of the lever 302 is manually pressed down, the outer lever arm is larger, which is more in line with the torque balance principle. The smaller downward pressure on the outer side can also make the inner side of the lever 302 rise. The connecting rod 301 is used to connect the lever 302 and the vertical sliding sleeve 200, so that the arc trajectory of the lever 302 rising can indirectly push the vertical sliding sleeve 200 to rise.
[0025] The support mechanism includes a square barrel 401, which is slidably connected to a support column 303. A through hole 402 is provided on the front side of the square barrel 401. The two ends of the base ring 600 are fixedly connected to the square barrel 401. Vertically equidistant support components are provided inside the through hole 402.
[0026] The square barrel 401 is used for sliding connection of the support column 303, and the through hole 402 is used for installing multiple support components.
[0027] The support assembly includes a rotating shaft 403, which is rotatably connected to a square barrel 401. A stop claw 404 is fixedly connected to the middle of the rotating shaft 403. A limit rod 405 is provided on the lower side of the stop claw 404. Both ends of the limit rod 405 are fixedly connected to the square barrel 401.
[0028] The pivot 403 is used to keep the stop claw 404 and the square barrel 401 rotatable. After the stop claw 404 rotates to the support angle, the limit rod 405 restricts the rotation of the stop claw 404, so that the stop claw 404 can support the support column 303.
[0029] The support assembly also includes a torsion spring 406, which is located on the outside of the rotating shaft 403. One end of the torsion spring 406 is fixedly connected to the rotating shaft 403, and the other end of the torsion spring 406 is fixedly connected to the square barrel 401. The front side of the blocking claw 404 is provided with a manually adjustable arc panel 407.
[0030] The torsion spring 406 is used to keep the stop pawl 404 in a supported state. At the same time, the stop pawl 404 can be adjusted by manually adjusting the arc panel 407, so that the stop pawl 404 can be stored in the through hole 402 without affecting the downward movement of the support column 303.
[0031] The locking mechanism includes a threaded sleeve 502, with a hexagonal head 503 fixedly connected to the bottom end of the threaded sleeve 502. The bottom surface of the locking ring body 100 is fixedly connected to an elastic arc panel 501 arranged in a circumferential array. The outer side of the elastic arc panel 501 is provided with threads, and the inner side of the threaded sleeve 502 is threadedly connected to the elastic arc panel 501.
[0032] The threaded sleeve 502 is threaded to the elastic arc panel 501, causing the elastic arc panel 501 to clamp inward, thereby clamping the steel rod. At the same time, due to the self-locking property of the threaded sleeve 502, the clamping is more secure.
[0033] The locking mechanism also includes a rotating ring 506, which is rotatably connected to the outside of the threaded sleeve 502. Vertical sliding columns 505 are fixedly connected to both ends of the rotating ring 506. The vertical sliding columns 505 are slidably connected to the vertical sliding sleeve 200. A limit block 504 is fixedly connected to the top of the vertical sliding column 505.
[0034] The rotating ring 506 is used to connect the vertical slide column 505, which is used to slide to connect the vertical slide sleeve 200. This facilitates pushing the rotating ring 506 and the threaded sleeve 502 upwards, making it easier for the threaded sleeve 502 to be threaded to the elastic arc panel 501. The limiting block 504 prevents the vertical slide column 505 from slipping.
[0035] Working principle:
[0036] Place the locking ring 100 on the outside of the steel rod, push the rotating ring 506 upward, and drive the threaded sleeve 502 to be placed on the outside of the elastic arc panel 501. Rotate the hexagonal head 503 to drive the threaded sleeve 502 to rotate, so that the threaded sleeve 502 is threadedly connected to the elastic arc panel 501, and gradually the elastic arc panel 501 is tightened inward to clamp the steel rod.
[0037] When the outer end of the lever 302 is manually pressed down, the inner end of the lever 302 rises due to the support and hinge of the support column 303, which pushes the connecting rod 301 to rise, thereby causing the vertical sliding sleeve 200 and the locking ring body 100 to rise. The elastic arc panel 501 on the lower side of the locking ring body 100 clamps the steel rod, ultimately causing the steel rod to be pulled out.
[0038] When lever 302 is pressed to its lowest position, the steel rod is pulled out. At this point, lifting the outer end of lever 302 causes the support column 303 to rise, and the bottom end of support column 303 rises, moving away from the lower blocking claw 404. The blocking claw 404 is then reset under the push of the torsion spring 406, serving as support for support column 303. The support point of support column 303 rises, and the fulcrum of lever 302 also rises accordingly, making it easier to press lever 302 down again to pull out the steel rod. Repeating this process multiple times will completely pull out the steel rod.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
