Abstract

The utility model discloses a tool for lens projection detection. The tool is made up of an outer disk and an inner ring, wherein the inner ring is matched with the outer disk via thread, and a step hole for placing the lens is formed in the inner ring. According to the tool for lens projection detection, threaded matching between the inner ring and the lens barrel is removed and a smooth inner surface is chosen, in the case of detection, the lens barrel is directly put into the step hole of the inner ring, no rotation is needed, and the detection efficiency is high; simultaneously due to no need of rotation, the service life of the inner ring is improved; and as the inner ring is designed to be in a cone frustum shape, the thickness of the inner ring is increased, and matching between the lens barrel and the projection tool can be ensured.

Description

The camera lens projection detects uses tool

Technical field

The utility model relates to a kind of camera lens projection detection tool.

Background technology

Existing projection detects and mainly is comprised of outer disk and inner ring with tool, and outer disk is fixed by screw thread and projector, and inner ring cooperates with outer disk by screw thread.

During detector lens, need the lens barrel of camera lens is screwed in the internal thread of inner ring, such method of operating is time-consuming very, and efficient is very low.

The utility model content

The purpose of this utility model is to provide a kind of camera lens projection to detect and uses tool, to improve detection efficiency, reduces labour intensity, improves the serviceable life of projection tool.

In order to reach above-mentioned purpose, solution of the present utility model is:

The camera lens projection detects and uses tool, is comprised of outer disk and inner ring, and inner ring cooperates with outer disk by screw thread, forms the stepped hole of placing for camera lens on the inner ring.

The external form of described inner ring is circular cone shape, in be formed centrally stepped hole, the bottom forms for the threaded column that is connected with outer disk; Outer disk center forms for the threaded hole that is connected with inner ring, and bottom outside forms for the external thread that is connected with projector.

After adopting such scheme, the utility model is selected smooth inside surface because of the threaded engagement of having removed between inner ring and the lens barrel, during detection, directly camera lens is put into the stepped hole of inner ring, need not rotate, and detection efficiency is very high.Owing to do not need rotation, can improve the serviceable life of inner ring simultaneously.

In addition, the utility model can also be circular cone shape with the exterior design of inner ring, has increased the thickness of inner ring, thereby guarantees the cooperation of camera lens and projection tool.

Label declaration

Outer disk 1 external thread 11 threaded holes 12

Inner ring 2 threaded column 21 stepped holes 22

Lens barrel 3.

Embodiment

The camera lens projection that the utility model discloses detects and uses tool, as shown in Figure 1 to Figure 3, is comprised of outer disk 1 and inner ring 2.

Outer disk 1 is fixed by screw thread and projector, and concrete structure can be: outer disk 1 bottom outside forms external thread 11 for being connected with projector.

Inner ring 2 is fixed by screw thread and outer disk 1, and concrete structure can be: threaded column 21 is formed on inner ring 2 bottoms, is formed centrally threaded hole 12 in the outer disk 1, cooperates with threaded hole 12 by threaded column 21 and realizes being connected and fixed of inner ring 2 and outer disk 1.Form stepped hole 22 on the inner ring 2 and be used for placing camera lens (being formed by eyeglass and lens barrel 3), specifically in inner ring 2, be formed centrally stepped hole 22.Like this, the utility model is selected smooth inside surface because of the threaded engagement of having removed between inner ring 2 and the lens barrel 3, during detection, directly camera lens is put into the stepped hole 22 of inner ring 2, need not rotate, and detection efficiency is very high.Owing to do not need rotation, can improve the serviceable life of inner ring 2 simultaneously.

In addition, present embodiment also further is circular cone shape with the exterior design of inner ring 2, having increased the thickness of inner ring 2, thereby guarantees the cooperation of camera lens 3 and projection tool.

The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.

Claims

1. the camera lens projection detects and uses tool, and it is characterized in that: be comprised of outer disk and inner ring, inner ring cooperates with outer disk by screw thread, forms the stepped hole of placing for camera lens on the inner ring.

2. camera lens projection as claimed in claim 1 detects and use tool, and it is characterized in that: the external form of described inner ring is circular cone shape, in be formed centrally stepped hole, the threaded column that confession is connected with outer disk is formed on the bottom; Outer disk center forms for the threaded hole that is connected with inner ring, and bottom outside forms for the external thread that is connected with projector.
