Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, it is the embodiment of the present invention discloses a tripod for a level, which comprises a supporting base 1. Be fixed with linking screw 11 on the upper surface of supporting seat 1, the axis perpendicular to supporting seat 1 place plane of linking screw 11, linking screw 11 can be connected with the surveyor's level for the surveyor's level can be fixed on supporting seat 1. Articulated on the lower surface of supporting seat 1 have three first landing leg 21, and first landing leg 21 is regular triangle and arranges on supporting seat 1, has increased the stability of supporting seat 1 when using for supporting seat 1 atress is more even.
Referring to fig. 1, the bottom end of the first leg 21 is provided with an internal thread, and the bottom end of the first leg 21 is connected with a screw rod 3 through a thread. A second leg 22 is connected to one end of the screw rod 3, which is far away from the first leg 21, in a threaded manner. The spiral half of the thread part of the screw rod 3 is left-handed and the spiral half is right-handed, that is, the thread directions of the two ends are opposite, so that when the screw rod 3 rotates in one direction, the first supporting leg 21 and the second supporting leg 22 on the screw rod 3 are separated towards the two ends or close towards the center. The bottom end of the second supporting leg 22 is hinged with a base 4, and a fixing component is arranged on the base 4 and can fix the base 4 on the ground.
When the utility model is used on a slope, the three first supporting legs 21 are opened, so that the base 4 is supported on the ground. The base 4 is fixed on the ground by using the fixing component, so that the base 4 is prevented from sliding on the slope. The screw rod 3 is rotated to adjust the distance between the first leg 21 and the second leg 22, so that the supporting seat 1 is adjusted to be in a horizontal state from an inclined state. Install the surveyor's level on supporting seat 1 through linking screw 11, guaranteed the steadiness when the surveyor's level uses.
Referring to fig. 1 and 2, the fixing assembly comprises a sleeve 5 hinged on the upper surface of the base 4 and a blade foot 6 slidably arranged in the sleeve 5. The blade foot 6 consists of a blade tip 62, a connecting rod 63 and a baffle plate 64. One end of the connecting rod 63 is fixedly connected with the blade tip 62, and the other end is fixedly connected with the baffle plate 64. The cutting edge 62 is of a conical structure, so that the cutting edge 6 can conveniently penetrate into the ground. The sleeve 5 can be rotated against the upper surface of the base 4 so that the axis of the sleeve 5 is perpendicular to the plane of the base 4. The base 4 is provided with a through hole 41, and when the sleeve 5 is pressed on the base 4, the through hole 41 and the sleeve 5 are aligned with each other, so that the blade 6 can penetrate through the through hole 41 and go deep into the ground.
