Description

Technical Field

[0001] The utility model relates to the field of optical tracking and positioning instruments, in particular to a supporting frame device of the optical tracking and positioning instrument. Background Art

[0002] The binocular vision positioning system is based on the principle of parallax, similar to human eyes. Two cameras are fixed on the same rigid body at a certain distance and angle. When working, the two cameras respectively obtain the mapping image of the same feature point in the field of view, and then calculate the specific position of the feature point in three-dimensional space through the principle of triangulation based on the placement of the two cameras and the position of the feature points obtained in the image. The position of multiple feature points can be dynamically obtained.

[0003] When the current binocular vision locator is used, the locator needs to be fixed on the instrument bracket. However, the existing fixing method is generally to directly connect the instrument bracket to the outer shell of the locator, which makes it difficult to adjust the position of the optical tracking locator. Some optical tracking locators have complex bracket structures, and often require tools to mobilize the bolts and other connecting structures on the bracket before the optical tracking locator can be moved. It is not easy to adjust and inconvenient to use. For this reason, we propose a support frame device for an optical tracking locator. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support frame device for an optical tracking and locating instrument, comprising an optical tracking and locating instrument and a vertical pole, wherein an adjustment mechanism is arranged on one side of the top of the vertical pole; the adjustment mechanism comprises a horizontal sleeve fixedly connected to the end face of the vertical pole, a groove opened on the side of the horizontal sleeve, a horizontal driving threaded rod rotatably arranged inside the horizontal sleeve, a movable ring threadedly connected to the outer surface of the horizontal driving threaded rod, a connecting block fixedly connected to one side of the movable ring, a longitudinal sleeve fixedly connected to one end of the connecting block passing through the groove, a square cavity opened inside the longitudinal sleeve, a longitudinal movable sleeve slidably arranged inside the square cavity, a movable block fixedly connected to the top of the longitudinal movable sleeve, a vertical driving threaded rod threadedly connected to the middle part of the movable block, and the adjustment mechanism is used to adjust the position of the optical tracking and locating instrument; the ends of the vertical driving threaded rod and the ends of the horizontal driving threaded rod are both provided with safety handles.

[0006] Preferably, the safety handle includes a limiting round block fixedly connected to the end surface of one end of the horizontal driving threaded rod extending to the outside of the transverse sleeve or the end surface of the vertical driving threaded rod extending to the outside of the longitudinal sleeve, two insertion holes symmetrically opened on the outer surface of the limiting round block, a driving ring sleeved on the outer surface of one end of the horizontal driving threaded rod or the outer surface of one end of the vertical driving threaded rod, and two insertion rods fixedly connected to the outer surface of the driving ring.

[0007] Preferably, the outer surfaces of the two plug rods are fixedly connected with rubber sleeves, one end of each rubber sleeve is plugged into the inside of the corresponding socket, and the end of each rubber sleeve plugged into the corresponding socket is configured to be hemispherical.

[0008] Preferably, both ends of the horizontal drive threaded rod are threadedly connected with a first transverse limiting nut and a second transverse limiting nut in sequence.

[0009] Preferably, two ends of the vertical drive threaded rod are threadedly connected with a first longitudinal limit nut and a second longitudinal limit nut in sequence.

[0011] Preferably, the bottom end of the longitudinally movable sleeve is connected to the top end of the optical tracking locator.

[0012] Technical effects and advantages of the utility model:

[0013] (1) The horizontal driving threaded rod or the vertical driving threaded rod is rotated through the safety handle. The horizontal driving threaded rod causes the moving ring to drive the connecting block to move along the groove, thereby driving the longitudinal sleeve to move, so as to adjust the horizontal position of the optical tracking locator. At the same time, the vertical driving threaded rod causes the moving block to move up or down along the inside of the square cavity, thereby driving the longitudinal moving sleeve to move, thereby changing the vertical position of the optical tracking locator. This design facilitates the user to adjust the position of the optical tracking locator by setting an adjustment mechanism, thereby facilitating the user to use it, and no other tools are required for auxiliary adjustment;

[0014] (2) By moving the driving ring away from the limiting circle, the rubber sleeve is separated from the socket. At this time, since the driving ring is sleeved on the horizontal driving threaded rod or the vertical driving threaded rod, even if the driving ring is rotated, the horizontal driving threaded rod or the vertical driving threaded rod will not rotate, which has good safety performance.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] The utility model provides Figure 1-5The support frame device of an optical tracking and positioning instrument shown in the figure comprises an optical tracking and positioning instrument and a vertical pole 1, and an adjustment mechanism is arranged on one side of the top of the vertical pole 1; the adjustment mechanism comprises a horizontal sleeve 2 fixedly connected to the end face of the vertical pole 1, a groove 3 provided on the side of the horizontal sleeve 2, a horizontal driving threaded rod 4 rotatably arranged inside the horizontal sleeve 2, a moving ring 5 threadedly connected to the outer surface of the horizontal driving threaded rod 4, a connecting block 6 fixedly connected to one side of the moving ring 5, a longitudinal sleeve 7 fixedly connected to one end of the connecting block 6 passing through the groove 3, a square cavity 10 provided inside the longitudinal sleeve 7, a longitudinal moving sleeve 8 slidably arranged inside the square cavity 10, a moving block 9 fixedly connected to the top of the longitudinal moving sleeve 8, and a vertical driving threaded rod 11 threadedly connected to the middle of the moving block 9, and the adjustment mechanism is used to adjust the position of the optical tracking and positioning instrument; the vertical driving threaded rod 1 The ends of 1 and the ends of the horizontal driving threaded rod 4 are both provided with safety handles; when the optical tracking locator needs to be adjusted, the horizontal driving threaded rod 4 or the vertical driving threaded rod 11 can be rotated through the safety handle, wherein the horizontal driving threaded rod 4 cooperates with the internal thread of the moving ring 5, so that the moving ring 5 drives the connecting block 6 to move along the groove 3, thereby driving the longitudinal sleeve 7 to move, so as to adjust the horizontal position of the optical tracking locator, and at the same time, the vertical driving threaded rod 11 cooperates with the middle thread of the moving block 9, so that the moving block 9 moves up or down along the inside of the square cavity 10, thereby driving the longitudinal moving sleeve 8 to move, thereby changing the vertical position of the optical tracking locator. This design facilitates the user to adjust the position of the optical tracking locator by setting an adjustment mechanism, thereby facilitating the user to use it, and no other tools are needed for auxiliary adjustment.

[0023] The optical tracking and positioning device with an adjustment mechanism can be used because the existing optical tracking and positioning device is not convenient to adjust the position or the adjustment operation is troublesome, so that it can be more convenient to use during medical treatment.

[0024] The two ends of the horizontal driving threaded rod 4 are threadedly connected with the first transverse limit nut 19 and the second transverse limit nut 20 in sequence; the first transverse limit nut 19 and the second transverse limit nut 20 are respectively located at the two ends of the transverse sleeve 2, and are infinitely close to the end surface of the transverse sleeve 2. The mutual cooperation between the first transverse limit nut 19 and the second transverse limit nut 20 can facilitate the rotation of the horizontal driving threaded rod 4 without moving up and down significantly.

[0025] The two ends of the vertical drive threaded rod 11 are threadedly connected with the first longitudinal limit nut 17 and the second longitudinal limit nut 18 in sequence; the square cavity 10 passes through the bottom of the longitudinal sleeve 7, wherein the first longitudinal limit nut 17 is located at the top of the square cavity 10 and is infinitely close to the top of the square cavity 10, and the second longitudinal limit nut 18 is located at the top of the longitudinal sleeve 7 and is infinitely close to the top of the longitudinal sleeve 7. The mutual cooperation of the first longitudinal limit nut 17 and the second longitudinal limit nut 18 can enable the vertical drive threaded rod 11 to rotate without moving up and down significantly.

[0026] The cross-sectional dimensions of the outer contour of the moving block 9 are matched with the cross-sectional dimensions of the inner contour of the longitudinal sleeve 7, and the cross-sectional dimensions of the outer contour of the moving block 9 are set to be a square; this facilitates the longitudinal sleeve 7 to limit the moving block 9, thereby preventing the moving block 9 and its longitudinal moving sleeve 8 from rotating.

[0027] The bottom end of the longitudinal movable sleeve 8 is connected to the top end of the optical tracking and positioning device; the connection between the optical tracking and positioning device and the longitudinal movable sleeve 8 can be achieved by using the existing optical tracking and positioning device and bracket connection method or other reasonable methods.

[0028] The safety handle includes a limiting round block 12 fixedly connected to the end surface of one end of the horizontal driving threaded rod 4 extending to the outer side of the horizontal sleeve 2 or the end surface of the vertical driving threaded rod 11 extending to the outer side of the longitudinal sleeve 7, two plug holes 14 symmetrically arranged on the outer surface of the limiting round block 12, a driving ring 13 sleeved on the outer surface of one end of the horizontal driving threaded rod 4 or the outer surface of one end of the vertical driving threaded rod 11 and two plug rods 15 fixedly connected to the outer surface of the driving ring 13; the outer surfaces of the two plug rods 15 are fixedly connected with rubber sleeves 16, one end of each rubber sleeve 16 is plugged into the inside of the corresponding plug hole 14, and the end of each rubber sleeve 16 plugged into the corresponding plug hole 14 is set to a hemispherical shape; when the optical tracking locator needs to be adjusted using the safety handle, move it toward the direction close to the limiting round block 12 The driving ring 13 is moved to connect the insertion rod 15 with the socket 14, so that the hemispherical end of the rubber sleeve 16 is smoothly inserted into the socket 14, and the rubber sleeve 16 is slightly deformed, thereby squeezing the inner wall surface of the socket 14, so that the position of the driving ring 13 is fixed, and then the driving ring 13 can be rotated to rotate the horizontal driving threaded rod 4 or the vertical driving threaded rod 11. When the safety handle is not needed, the driving ring 13 is moved away from the limiting circle 12 to separate the rubber sleeve 16 from the socket 14. At this time, since the driving ring 13 is sleeved on the horizontal driving threaded rod 4 or the vertical driving threaded rod 11, even if the driving ring 13 is rotated, the horizontal driving threaded rod 4 or the vertical driving threaded rod 11 will not rotate, and it has good safety performance in use.
