Description

Prism group closing device

Technical Field

The utility model relates to a it compresses tightly fixed technical field, concretely relates to prism group closing device to look into prism group in the system of telescope.

Background

In the aspect of internal structure of a telescope prism and optical design of schematic diagrams, a common telescope generally adopts one of two basic designs: roof (Roof) or puro (Porro, also paul, puro) prisms. The Proro prism is also called a right-angle prism, is a traditional classical design, is formed by two identical right-angle prisms in a common design, has the advantages of simple shape, easy processing and assembly and larger weight and volume compared with a roof prism. The roof prism system is also called as a Pechan prism system, and the common design is composed of a roof prism and a half-pentaprism, and has the advantages that the appearance is a straight cylinder type, and the optical structure is relatively light. The prism is more suitable for portable products for outdoor sports, has particularly obvious advantages of volume and weight on products with small calibers, and has the disadvantages that even a relatively simple roof prism has a more complex appearance than a Proc prism, has high processing difficulty, and is difficult to be used in the traditional Proc prism from the aspects of assembly difficulty and maintainability, so the cost is higher.

Roof prism is because light relatively, portable reason, and the application is extensive in daily life, and there is prism face to compress tightly technical problem, mainly embodies at roof prism in the course of manufacturing in processing: the thickness of the combined prism is different due to processing and manufacturing errors, the prism surface cannot be simultaneously contacted with the pressing plate when the combined prism is pressed and fixed, wherein the thick prism can be pressed and fixed, and the thin prism cannot be pressed and fixed. In the prior art, a flat plate and silica gel are mainly adopted for compressing and fixing. Due to processing and manufacturing errors, the thickness of the prisms in the prism group has errors. When the flat plate and the silica gel are adopted for pressing, the silica gel is easy to leak into the prism group, is not easy to wipe, and reduces the working efficiency.

In view of this, it is desirable to design a prism group pressing device, which effectively solves the problem of pressing and fixing the prism group and improves the working efficiency.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a prism group closing device, effectual solution prism group compresses tightly fixed problem, improves work efficiency.

In order to realize the above object, the technical scheme of the utility model is that: a prism group pressing device is characterized by comprising: the clamp plate, the screw has been seted up on the clamp plate, the fixed anti-skidding base that is equipped with on the clamp plate, at least one antiskid circle mounting groove has been seted up on the anti-skidding base, the embedding has the antiskid circle in the antiskid circle mounting groove.

Further, the clamp plate is square, and the screw sets up the apex angle department at this square board.

Furthermore, the screw is two, two the screw sets up respectively the adjacent apex angle department of square board, two the screw passes through bolt and telescope body fixed connection.

Furthermore, the antiskid circle mounting groove is two, two antiskid circle mounting grooves correspond prism group setting respectively.

Furthermore, the antiskid ring mounting groove is an annular groove, the sealing ring is tightly embedded with the antiskid ring mounting groove, and the sealing ring partially protrudes out of the antiskid ring mounting groove.

Furthermore, the sealing ring is a rubber ring and is used for being tightly attached to the side wall of the prism group.

Has the advantages that:

the utility model provides a pair of prism group closing device adopts the combination of sealing washer and clamp plate to replace traditional silica gel to compress tightly fixed mode, with the sealing washer embedding advance in the sealing washer mounting groove of clamp plate, through clamp plate extrusion fixed prism group, because the sealing washer receives the extrusion can produce deformation, so veneer prism and ridge prism can both be extruded fixedly. Under the mode that original flat plate is kept to compress tightly fixedly, increase two at least sealing washers, utilize the compressive deformation of sealing washer to deal with combination prism thickness error. Under the condition of not changing the installation mode, the problem that the prism cannot be compressed due to thickness errors is solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in fig. 1-2, the utility model discloses a prism group closing device, clamp plate 1, screw 11 has been seted up on the clamp plate 1, the fixed anti-skidding base 12 that is equipped with on the clamp plate 1, at least one antiskid ring mounting groove 13 has been seted up on the anti-skidding base 12, the embedding has antiskid ring 2 in the antiskid ring mounting groove 13. In the scheme, the method comprises the following steps: the novel glass mirror comprises a mirror body 3, a cemented prism 4, a light fence piece 5, a roof prism 6, an anti-slip ring 2 and a pressing plate 1, wherein a prism mounting groove 31 is formed in the mirror body 3, the cemented prism 4, the light fence piece 5 and the roof prism 6 are sequentially combined together, the integrated mounting is carried out in the prism mounting groove 31, an anti-slip ring mounting groove 13 is formed in the inner wall of the pressing plate 1, the anti-slip ring 2 is embedded into the anti-slip ring mounting groove 13, and the whole of the pressing plate 1 and the anti-slip ring 2 is fixedly mounted on the mirror body 3 through bolts. With veneer prism 4, light fence piece 5 and roof prism 6 longitudinal combination in proper order, then in the whole embedding prism mounting groove 31 that will make up and form, because fixed connection does not exist between each prism this moment, the whole that forms of combination simultaneously and prism mounting groove 31 do not have the fixed connection relation, so need have clamp plate 1 to compress tightly veneer prism 4 and roof prism 6 this moment, and traditional art adopts the flat board to add silica gel to compress tightly fixedly, in the silica gel leaks into the prism group easily, be difficult for wiping, work efficiency has been reduced.
