Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, a total station comprises a support table 1. The main machine 2 is arranged on the upper surface of the supporting table 1, and three supporting columns 21 are fixed on the lower surface. The three support columns 21 are placed obliquely. The support table 1 is fixedly connected with a support block 23 through a fixing rod 22. The support blocks 23 are located between the three support columns 21. The support block 23 is rotatably connected to a drive rod 24 via a bearing. The circle center enclosed by the joints of the three support columns 21 and the support table 1 is on the axis extension line of the drive rod 24.

The upper part of the driving rod 24 is a polished rod, and the middle part and the lower part are screws. The polished rod and the screw rod are integrally arranged. The support column 21 is sleeved with a sliding sleeve 4. A driving block 30 is threadedly connected to the screw. The sliding sleeve 4 is connected with the driving block 30 through the telescopic rod 3. The telescopic rod 3 comprises a sleeve 31 and an inner rod 32. An inner rod 32 is slidably connected within the sleeve 31. The end of the sleeve 31 far away from the inner rod 32 is fixed on the driving block 30, and the end of the inner rod 32 far away from the sleeve 31 is fixed on the outer wall of the sliding sleeve 4.

The driving rod 24 is rotated, and the driving block 30 can move along the length direction of the driving rod 24 through the transmission effect of the threads, so that the sliding sleeve 4 can move up and down along the supporting column 21, and the operation is simple and convenient.

One end of the sliding sleeve 4 far away from the support table 1 is connected with a positioning cone 42 through a power mechanism 5. The power mechanism 5 includes a power lever 51, a worm wheel 52, a worm 53, a cam 54, and a connecting rod 55. The power rod 51 is rotatably connected to the sliding sleeve 4, and the worm 53 is fixedly connected with the power rod 51. The power rod 51 is arranged coaxially with the worm 53. The worm wheel 52 is rotatably coupled to the slide sleeve 4 and is engaged with the worm 53. The cam 54 is fixed to the outer wall of the worm wheel 52. One end of the connecting rod 55 is hinged to the cam 54 and the other end is hinged to the positioning cone 42. A circular truncated cone sleeve 41 is fixed at one end of the sliding sleeve 4 close to the positioning cone 42, and the positioning cone 42 is arranged in the circular truncated cone sleeve 41 to protect the positioning cone 42 and prevent the positioning cone 42 from hurting people.

And a limiting mechanism for positioning the power rod 51 is arranged on the outer wall of the sliding sleeve 4. The limiting mechanism comprises an elastic sheet, a limiting ring and a limiting groove. The limiting ring is fixed on the outer wall of the sliding sleeve 4, and the power rod 51 is positioned inside the limiting ring. A plurality of limiting grooves are arranged on one side of the limiting ring back to the sliding sleeve 4. One end of the elastic sheet is fixed on the outer wall of the power rod 51, and the other end is arranged in the limiting groove. The pivoted in-process of power rod 51 drives the flexure strip and rotates along power rod 51's axle center, and the flexure strip is contradicted with the inner wall of spacing groove, loosens power rod 51 back, inlays through the flexure strip and locates in the spacing groove, realizes spacing to power rod 51. The operation is simple. In this embodiment, the elastic piece is made of spring steel.

A pedal 56 is integrally provided on an outer wall of the slide bush 4, and a plurality of anti-slip grooves 561 are formed on an upper surface of the pedal 56.

The support table 1 is provided with a button 70. The button 70 is connected to the knob 8 by the positioning slider 6. The positioning sliding mechanism 6 includes a positioning sleeve 61, a first slide block 62, a first inclined surface 63, a second slide block 64, a second inclined surface 65, a slide rod 66, a third inclined surface 67, a slide groove 68, and a first elastic member 69. The first elastic member 69 is a spring. A mounting hole 621 is formed on the support base 1. The positioning sleeve 61 is fixed in the mounting hole 621. The button 70 is slidably attached to the positioning sleeve 61 up and down. And fixedly connects the button 70 to the first slider 62. The first inclined surface 63 is formed at an end of the first slider 62 facing away from the button 70. The second slider 64 is placed in the positioning sleeve 61, and the second inclined surface 65 is formed at an end of the second slider 64 facing the first slider 62. When the second slide block 64 is located in the positioning sleeve 61, the first slide block 62 and the second slide block 64 are abutted, and the first inclined surface 63 and the second inclined surface 65 are misaligned. The slide bar 66 is fixed to the outer wall of the second slider block 64. The sliding groove 68 is formed on the outer wall of the positioning sleeve 61, and the third inclined surface 67 is formed at the end of the positioning sleeve 61 far away from the button 70. One end of the first elastic member 69 abuts against the second slider 64, and the other end is fixed to the support table 1, so that the first elastic member 69 always applies an elastic force to the second slider 64 in a direction approaching the first slider 62. The end of the second slider 64 remote from the first slider 62 is connected to the knob 8 by a bearing.

When the button 70 is pressed, the first slider 62 pushes the second slider 64 to move in a direction away from the positioning sleeve 61, and the second slider 64 is ejected out of the positioning sleeve 61, the first inclined surface 63 and the second inclined surface 65 are aligned by dislocation and rotation, so that the second slider 64 rotates at a certain angle, the slide rod 66 slides out of the slide groove 68 and corresponds to the third inclined surface 67 along with the rotation of the second slider 64, the button 70 is released, the slide rod 66 is embedded on the third inclined surface 67 through the elastic force of the first elastic member 69, the positioning of the slide rod 66 and the second slider 64 is realized, and the knob 8 moves in a direction close to the driving rod 24 and is positioned. When the button 70 is pressed again, the first slider 62 abuts against the second slider 64, and the second slider 64 is ejected from the positioning sleeve 61, so that the sliding rod 66 is separated from the third inclined surface 67 and corresponds to the sliding slot 68, the button 70 is released, the sliding rod 66 is slidably connected in the sliding slot 68 through the elastic force of the first elastic member 69, and meanwhile, the second slider 64 is placed in the positioning sleeve 61, and the knob 8 is separated from the driving rod 24.

To facilitate the connection and disconnection of the knob 8 to and from the driving rod 24. A linkage assembly 7 is provided between the knob 8 and the drive rod 24. The linkage assembly 7 includes a positioning slot 71, a second elastic member 72, a positioning post 73, and a guiding inclined surface 74. The knob 8 is provided with a connection concave hole 75. The second elastic member 72 is a spring, one end of which is fixed on the inner wall of the connecting concave hole 75, and the other end of which is fixed on the positioning column 73. A guiding inclined surface 74 is formed at an end of the positioning pillar 73 away from the second elastic member 72. A plurality of positioning grooves 71 are formed on the outer wall of the polish rod.

When knob 8 toward the direction removal that is close to the polished rod, reference column 73 acts on the outer wall conflict of polished rod through the guide of guide inclined plane 74, then through the spring action of second elastic component 72, leans on reference column 73 top on the inner wall of constant head tank 71, produces great frictional force, rotates knob 8, can realize through the effect of frictional force that actuating lever 24 rotates. When the knob 8 moves away from the polish rod, the knob 8 is separated from the driving rod 24, so that the driving rod 24 is not easy to rotate randomly.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
