Description

Technical Field

[0001] The utility model relates to the technical field of telescope manufacturing, in particular to a telescope rapid centering device. 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, and then pass through a magnifying eyepiece to be seen. It is also called a "telescope". The first function of a telescope is to magnify the angle of distant objects so that the human eye can see details with smaller angular distances. The second function of a telescope is to send the light beam collected by the objective lens, which is much thicker than the pupil diameter (maximum 8 mm), into the human eye, so that the observer can see dim objects that were originally invisible.

[0003] The Chinese patent with patent announcement number CN210605183U discloses a telescope rapid centering device. The telescope rapid centering device comprises: a semicircular box, the top of which is provided with an opening; a telescope, which is arranged in the semicircular box; a first clamping plate, which is arranged in the semicircular box and contacts the telescope; a second clamping plate, which is arranged in the semicircular box and contacts the telescope; a first cross bar, which is fixedly mounted on the side of the second clamping plate away from the telescope. The telescope rapid centering device provided by the utility model has the advantages of being easy to use, being able to quickly center the telescope, and being simple and convenient to operate.

[0004] However, the above design still has some shortcomings. In the above design, the elasticity of the spring is used to achieve rapid centering of the telescope. However, as the use time increases, the elasticity of the spring will gradually decrease, and it is likely that the telescope will not be able to be centered or the centering effect will be poor, which makes it difficult to meet the use requirements.

To this end, the purpose of this utility model is to provide a telescope rapid centering device, which can effectively solve the problem of reduced spring elasticity and meet the requirements of rapid centering of the telescope.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a telescope rapid centering device, including a box and a transmission mechanism, the top of the box is fixedly connected to a mounting column, the front end surface of the mounting column is rotatably provided with a rotating plate, the inside of the box is provided with a telescope body, the bottom of the telescope body is provided with a first clamping plate, the top of the telescope body is provided with a second clamping plate, and the top of the second clamping plate is provided with a transmission mechanism.

[0007] Furthermore, the transmission mechanism includes a worm, and the front end of the worm is fixedly connected to the rear end of the rotating plate, and one side of the worm is transmission-connected to a worm wheel.

[0008] A rotating rod is fixedly connected inside the worm wheel, and a screw rod is fixedly connected at the bottom of the rotating rod.

[0009] The outer wall of the screw rod is threadedly connected with a moving block, and the bottom of the moving block is fixedly connected to the top of the second clamping plate.

[0010] The surface of the moving block is provided with a threaded hole matched with the screw rod, and the moving block is threadedly connected with the screw rod through the threaded hole provided on the surface of the moving block.

[0011] The ends of the first clamping plate and the second clamping plate close to each other are both fixedly connected with a protection pad.

[0012] The beneficial effects of the utility model are as follows: the telescope can be quickly centered through the structural design of the rotating plate, the second clamping plate and the transmission mechanism, and the self-locking effect can be achieved through the mutual cooperation of the worm wheel and the worm, thereby improving the centering effect, and solving the problem of using the elasticity of the spring to achieve rapid centering of the telescope, but with the increase of the use time, the elasticity of the spring will gradually decrease, and finally it is very likely that the centering cannot be achieved or the centering effect is poor, and it is difficult to meet people's use needs.

[0013] By providing the protective pad, when the first clamping plate and the second clamping plate are used to center the telescope, the protective pad can be used to reduce the vibration of the telescope body, thereby protecting the telescope body and improving the practicability of the device.

[0022] Specifically, Figure 1 , Figure 2 and Figure 3As shown, when the telescope needs to be centered, the rotating plate 3 can be rotated, and the rotating plate 3 drives the worm 804 to rotate. The worm 804 rotates through the worm wheel 801 to drive the rotating rod 802 to rotate. The rotating rod 802 drives the screw 803 to rotate.
