Description

Technical Field

[0001] The utility model relates to the field of telescope brackets, in particular to an adjustable expansion bracket for a telescope. Background Art

[0002] A telescope is an optical instrument that uses lenses, reflectors and other optical devices to observe distant objects. It uses the refraction of light passing through the lens or the reflection of light by a concave mirror to make it enter a small hole and converge into an image, which is then seen through a magnifying eyepiece. It is also called a "telescope."

[0003] However, although the prior art has many technical advantages, the disadvantage is that when the traditional telescope expansion bracket is in use, the length of the legs is fixed, so it cannot adapt to the requirements of different height positions, thereby limiting the fixed position of the telescope, causing inconvenience to the user.

[0007] A reinforcement mechanism, the reinforcement mechanism is used to reinforce the support frame, and the outer wall of the reinforcement mechanism is fixedly connected to the inner wall of the fixed plate;

[0008] An auxiliary mechanism, the top of which is fixedly connected to the bottom of the reinforcement mechanism;

[0009] The support frame includes a rotating rod, the outer wall of the rotating rod is fixedly connected to an upper leg, the inner wall of the upper leg is slidably connected to a lower leg, the bottom of the lower leg is fixedly connected to a foot, the outer wall of the upper leg is fixedly connected to an adjusting cylinder, the inner wall of the adjusting cylinder is threadedly connected to an adjusting bolt through a threaded hole, and the threaded hole is opened in the wall of the adjusting cylinder, and the outer wall of the adjusting bolt is fixedly connected to an auxiliary rod.

A connecting thread segment is provided in the wall of the connecting rod, the outer wall of the auxiliary plate contacts the outer wall of the upper leg, and the top of the fixing knob contacts the bottom of the auxiliary plate.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a support frame, and adjusts the required length of each leg by sliding the lower leg in the upper leg. After the length is adjusted, the adjusting bolt is rotated through the auxiliary rod, and the adjusting bolt is threadedly connected with the adjusting tube to make the adjusting bolt close to and contact the lower leg.

At this time, the fixing knob is screwed in through the fixed threaded section so that the top of the fixing knob contacts the bottom of the auxiliary plate, as shown in the figure, thereby assisting the fixation of the support frame and achieving the effect of further improving the stability of the support frame.

[0025] A connecting piece 11 is fixedly connected to the bottom of the fixed plate 1, and the inner wall of the connecting piece 11 is rotatably connected to the outer wall of the rotating rod 21 through a bearing. The outer wall of the lower leg 23 is slidably connected to the inner wall of the adjusting cylinder 25, and the end of the adjusting bolt 26 away from the auxiliary rod 27 is in contact with the outer wall of the lower leg 23.

[0026] The reinforcement mechanism 3 includes a rotating drum 31 , the bottom of which is fixedly connected with a spiral reinforcement member 32 , the inner wall of the rotating drum 31 is threadedly connected to the outer wall of the lower leg 23 via a reinforcement threaded hole 311 , and the reinforcement threaded hole 311 is opened in the wall of the rotating drum 31 .

[0027] The auxiliary mechanism 4 includes a connecting rod 41, an auxiliary plate 42 is slidably connected to the outer wall of the connecting rod 41, and a fixing knob 43 is threadedly connected to the outer wall of the connecting rod 41 through a fixing thread segment 412, and the fixing thread segment 412 is opened in the wall of the connecting rod 41. A connecting thread segment 411 is opened in the wall of the connecting rod 41, the outer wall of the auxiliary plate 42 contacts the outer wall of the upper leg 22, and the top of the fixing knob 43 contacts the bottom of the auxiliary plate 42.

[0028] Working principle:

[0029] When in use, an auxiliary mechanism 4 is set up, in which a connecting threaded section 411 is provided near the top of the connecting rod 41 for connecting the telescope to the fixed plate 1, and three support frames 2 are rotatably connected to the connecting member 11 to support the fixed plate 1, so that the triangular fixation is more stable, and the stability of the lower leg 23 is reinforced by setting the reinforcing mechanism 3, and the support of the upper leg 22 is assisted by setting the auxiliary mechanism 4.

[0030] When the support frame 2 is in use, the required length of each leg is first adjusted by sliding the lower leg 23 in the upper leg 22, and then the upper leg 22 is rotated to the maximum opening angle by the rotating rod 21, wherein the upper leg 22 is a hollow tube, and its inner diameter is consistent with the outer diameter of the lower leg 23. After adjusting the length, the adjusting bolt 26 is rotated through the auxiliary rod 27, and the adjusting bolt 26 is threadedly connected with the adjusting tube 25, so that the adjusting bolt 26 is close to and contacts the lower leg 23.

[0031] When fixing on soft soil, a reinforcement mechanism 3 is set up, in which a rotating drum 31 is threadedly connected to the lower leg 23 through a reinforcement threaded hole 311. Under the action of the threaded connection, the rotating drum 31 is twisted to move downward along the axis of the lower leg 23. The spiral reinforcement 32 is sleeved on the outside of the support leg 24 and does not contact the support leg 24. The spiral reinforcement 32 is hard stainless steel. The spiral reinforcement 32 is driven by the rotating drum 31 to move downward, so that the spiral reinforcement 32 is rotated into the soil, and the spiral structure is stuck in the soil, thereby playing a reinforcement role.

[0032] After the support frame 2 is fixed, the auxiliary mechanism 4 is set to make the auxiliary plate 42 slide upward on the connecting rod 41, so that the three notches extending from the auxiliary plate 42 contact the upper leg 22. At this time, the fixing knob 43 is screwed in through the fixing thread section 412, so that the top of the fixing knob 43 contacts the bottom of the auxiliary plate 42, as shown in the figure, thereby assisting the fixation of the support frame 2.
