Description

Technical Field

[0001] The utility model relates to the technical field of telescopes, in particular to a Paul type telescope hanging prism group. Background Art

[0002] The Porro prism is an isosceles right-angle prism made of glass blocks, with the end plane facing the right angle. In use, light enters from the largest rectangular surface of the prism, undergoes two total reflections on the inclined surface, and then penetrates the original incident plane and exits. Because the light only enters and exits in a normal state, the prism does not have a dispersion effect, but the image passing through the Porro prism will be flipped 180° and will move in the original direction of entry, that is, the direction of the Porro prism also changes 180°. Porro prisms are most often used in pairs as a combination of double Porro prisms.

[0003] The patent announcement number is CN206848573U, which is a Porro-type telescope suspended prism group, comprising a first prism, a second prism and a filter lens, wherein the first prism and the second prism are suspended in a telescope housing through a prism bracket. A filter lens is arranged between the first prism and the second prism. An opening matching with the filter lens is arranged on one side of the housing, a convex ridge is arranged at a position opposite to the opening on the inner surface of the housing, a groove matching with the filter lens is arranged on the convex ridge, and the filter lens is inserted into the housing through the opening and the edge is clamped in the groove. The utility model makes full use of the multiple reflection characteristics of the Porro prism, and arranges the filter lens between the prisms, which can greatly improve the filtering effect and is very convenient to use.

[0004] The working principle of the above patent is to manually operate the lateral movement or replacement of the filter lens, which is similar to the principle of card insertion and removal. However, the two prisms cannot be adjusted during use, and it is not convenient to disassemble and maintain the prisms. In addition, the Porro prism is easily disturbed by the outside world during long-term outdoor use and storage, and the lens will be affected by moisture, which will affect the observation effect. Therefore, specific storage tools are required. Therefore, the above patented equipment is not conducive to carrying for outdoor sports. Utility Model Content

[0022] 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.

[0023] In order to better observe the distant landscape during outdoor travel, you need to use a Porro telescope to view the landscape. When using this device for observation, you need to ensure the tightness of the connection between the cover and the shell. A sealing gasket can be set between the cover and the shell to increase the overall sealing. The moving range of the mounting bracket needs to be limited.
