Description

Technical Field

[0001] This utility model belongs to the field of infrared continuous zoom lens technology, and in particular relates to a fixed bracket for infrared continuous zoom lenses. Background Technology

[0002] An infrared continuous zoom lens is an optical device designed specifically for the infrared band. It achieves clear imaging of targets at different distances by continuously adjusting the focal length. It is widely used in security monitoring, industrial inspection, military reconnaissance and other fields. The fixed bracket is the basic structural component of the infrared continuous zoom lens, which is used to support the zoom ring, lens group and linear motor.

[0003] Currently, special protrusions need to be set on the fixed bracket for the installation of linear motors, which increases the complexity of the bracket, increases the manufacturing cost of the bracket, and makes the bracket less versatile. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed bracket for an infrared continuous zoom lens in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fixing bracket for an infrared continuous zoom lens, comprising:

[0006] The fixing cylinder is cylindrical and has multiple waist-shaped grooves.

[0007] The base is a flange seat, and the base is connected to one end of the fixed cylinder;

[0008] A filter ring support is connected to the other end of the fixed cylinder;

[0009] At least one motor mounting tube is connected to the base.

[0010] As a further description of the above technical solution:

[0011] The base is sleeved on the fixed cylinder, and the connecting ring connects the base and the fixed cylinder through multiple fixing bolts.

[0012] As a further description of the above technical solution:

[0013] The filter ring support is connected to the end of the fixed cylinder by multiple fixing bolts, and the filter ring support is provided with multiple connection holes.

[0014] As a further description of the above technical solution:

[0015] One end of the motor mounting tube is connected to the base via multiple fixing bolts, and the other end of the motor mounting tube is provided with a flange.

[0016] As a further description of the above technical solution:

[0017] The motor mounting tube is provided with a wiring groove.

[0018] As a further description of the above technical solution:

[0019] The motor mounting tube is equipped with reinforcing ribs.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this utility model, the assembly structure design between the fixed cylinder, the base, the filter ring support, and the motor fixing tube is adopted. The motor fixing tube is used to replace the linear motor mounting structure set on the fixed cylinder, which simplifies the structural design of the fixed cylinder, makes the overall bracket design simple, and reduces the manufacturing cost of the bracket. Only by changing the size and installation position of the motor fixing tube, the installation of the linear motor in different positions can be met, making the bracket highly versatile.
