Description

Technical Field

[0001] The utility model relates to the technical field of lens spacers, in particular to a durable lens spacer. Background Art

[0002] A spacer is an annular part used to maintain a specified axial distance between two bearing rings or bearing washers. An optical lens is formed by combining multiple lenses, and usually a spacer is installed between two lenses to maintain the axial distance between the lenses.

[0003] The commonly used spacer at present is an annular ring made of rubber with a certain hardness. When in use, the lens is installed in the lens barrel, and then the spacer is installed between two adjacent lenses. The spacer plays a role of spacing and distance setting between two adjacent lenses.

[0004] For the above technical conditions, there are still defects that the current spacer is prone to force-induced distortion and deformation, making the spacer less durable and having a shorter service life.

[0005] Based on this, the utility model designs a durable lens spacer to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a durable lens spacer to solve the above technical problems.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a durable lens spacer, including the main body of the spacer. A V-shaped groove is opened on the main body. The main body includes an upper ring and a lower ring. The V-shaped groove is between the lower ring and the upper ring. The lower ring is provided with two insertion slots. The insertion ring is fixedly arranged on the upper ring and is inserted into the insertion slot. The lower ring is provided with a metal ring between the two insertion slots. The upper ring is provided with a fixing slot, and the metal ring is inserted into the fixing slot. The metal ring is between the upper ring and the lower ring.

[0008] Preferably, the lower ring is provided with an installation slot, and the metal ring is inserted into the installation slot. The metal ring is between the installation slot and the fixing slot.

[0009] Preferably, a plurality of limiting slots are opened on the main body.

[0010] Preferably, the insertion ring includes a fixing ring and a clamping ring. The fixing ring is fixedly arranged on the upper ring, and the clamping ring is fixedly arranged on the fixing ring. The diameter of the clamping ring is larger than that of the fixing ring, and the side of the clamping ring away from the fixing ring is chamfered.

[0011] In summary, the present application has the following beneficial technical effects: when the spacer ring is subjected to an external force, the upper ring and the lower ring respectively sense the action of the external force, and then conduct the external force to the metal ring. Since the metal ring is made of metal, and the metal has a certain hardness and strength and is not easily deformed under force, therefore, the main body is not easily distorted under the action of the metal ring, the service life of the main body is extended, the durability of the main body is increased, and the effect that the spacer ring is not easily distorted under force is achieved.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0021] The following will Figures 1-5 further describe the present application in detail.

[0022] A durable lens spacer ring, comprising a main body of the spacer ring, on which there are two V-shaped grooves 3 provided. The main body includes an upper ring 1 and a lower ring 2, and the V-shaped grooves 3 are between the upper ring 1 and the lower ring 2. The upper ring 1 is connected to the lower ring 2, and on one side of the lower ring 2 close to the upper ring 1, there are two insertion slots 9 provided.

[0023] On one side of the upper ring 1 close to the lower ring 2, there is fixedly provided an insertion ring 8 adapted to the insertion ring 8, and the insertion ring 8 is inserted into the insertion slot 9. The insertion ring 8 and the insertion slot 9 fix the upper ring 1 to be installed on the lower ring 2. The lower ring 2 is provided with an installation slot 7, and a metal ring 5 is arranged in the installation slot 7. There is a fixing slot 6 on the upper ring 1, and the metal ring 5 is inserted into the fixing slot 6. The metal ring 5 is between the upper ring 1 and the lower ring 2.

[0024] The metal ring 5 is made of a metal material, has a certain hardness and strength, and is not easily distorted and deformed under force. When the main body is subjected to an external force, due to the action of the metal ring 5 between the upper ring 1 and the lower ring 2, the main body is not easily distorted and deformed under force.

[0025] The lower ring 2 is provided with an installation slot 7, and the metal ring 5 is inserted and arranged in the installation slot 7. The metal ring 5 is between the fixing slot 6 and the installation slot 7. The metal ring 5 is detachably arranged in the main body, which is convenient to replace metal rings 5 with different hardnesses and strengths according to the usage requirements.

[0026] The main body is provided with a plurality of limiting slots 4, and the limiting slots 4 play a role in limiting when the main body is installed in the lens, so that the main body is not easily moved in the lens.

[0027] The insertion ring 8 includes a fixing ring 10 and a clamping ring 11. The fixing ring 10 is fixedly arranged on the upper ring 1, and the clamping ring 11 is fixedly arranged on the fixing ring 10. The diameter of the clamping ring 11 is larger than that of the fixing ring 10, so that the insertion ring 8 is not easily detached from the insertion slot 9. One side of the clamping ring 11 away from the fixing ring 10 is chamfered, which is convenient for the clamping ring 11 to be clamped in the insertion slot 9.

[0028] The implementation principle of this embodiment is: when the spacer ring is subjected to an external force, the upper ring 1 and the lower ring 2 respectively feel the external force and then conduct the external force to the metal ring 5. Since the metal ring 5 is made of metal and the metal has a certain hardness and strength and is not easily deformed under force, therefore, the main body is not easily distorted and deformed under the action of the metal ring 5, the service life of the main body is prolonged, the durability of the main body is increased, and the effect that the spacer ring is not easily distorted and deformed under force is achieved.
