Description

Technical Field

[0001] This utility model belongs to the field of infrared continuous zoom lens technology, and in particular relates to a mid-wave infrared continuous zoom lens base. Background Technology

[0002] A mid-wave cooled infrared continuous zoom lens is an optical imaging device that combines mid-wave infrared imaging technology, cooling technology, and continuous zoom function. It is mainly used to achieve clear observation and tracking of targets in the infrared band. The base is a platform used to fix the detector, lens, and cooler.

[0003] Currently, the detector, lens, and cooler are directly fixed to the platform using fasteners, which makes it inconvenient to inspect and maintain any particular module later. Utility Model Content

[0004] The purpose of this utility model is to provide a mid-wave infrared continuous zoom lens base in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mid-wave infrared continuous zoom lens base, comprising:

[0006] A base plate having a first and a second sliding groove;

[0007] The lens mounting plate is slidably connected within the first groove;

[0008] A detector mounting base is slidably connected in the second slide groove, and a third slide groove is provided on the detector mounting base;

[0009] A bidirectional lead screw is mounted on the base plate via a bearing seat, and the positive and negative threads of the bidirectional lead screw are respectively screwed to the lens fixing plate and the detector fixing seat;

[0010] The cooler mounting plate is slidably connected within the third groove.

[0011] A one-way lead screw is mounted on the detector mounting base via a bearing seat, and the one-way lead screw is screwed to the cooler mounting plate. The axis of the one-way lead screw coincides with the axis of the two-way lead screw.

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

[0013] The lens mounting plate is equipped with two clamps.

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

[0015] The second slide groove is provided with multiple guide rods, and the detector mounting base is slidably connected to the multiple guide rods.

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

[0017] Both the bidirectional lead screw and the unidirectional lead screw are equipped with knobs at one end, and the two knobs are located on the same side of the cooler fixing plate.

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

[0019] The inner walls of the first slide and the third slide are provided with limiting grooves, and the opposite sides of the lens fixing plate and the opposite sides of the cooler fixing plate are provided with limiting strips, which are engaged in the corresponding limiting grooves.

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

[0021] In this invention, the lens is fixed on the lens mounting plate, the detector is fixed on the detector mounting base, and the cooler is fixed on the cooler mounting plate. The positioning structure is modularly designed. Only by rotating the bidirectional lead screw can the lens mounting plate and the detector mounting base move synchronously, and by rotating the unidirectional lead screw can the cooler mounting plate slide on the detector mounting base. This allows the modules to be quickly connected or separated, which facilitates the subsequent inspection and maintenance of a particular module. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a mid-wave infrared continuous zoom lens base, comprising:

[0032] The base plate 1 has a first groove 2 and a second groove 3.

[0033] The lens fixing plate 4 is slidably connected within the first slide groove 2;

[0034] The detector mounting base 5 is slidably connected in the second slide groove 3, and the detector mounting base 5 is provided with a third slide groove 6;

[0035] A bidirectional lead screw 7 is mounted on the base plate 1 via a bearing seat, and the positive and negative threads of the bidirectional lead screw 7 are respectively screwed to the lens fixing plate 4 and the detector fixing seat 5;

[0036] Cooler fixing plate 8 is slidably connected in the third slide groove 6;

[0037] A one-way lead screw 9 is mounted on the detector mounting base 5 via a bearing seat, and the one-way lead screw 9 is screwed to the cooler mounting plate 8. The axis of the one-way lead screw 9 coincides with the axis of the two-way lead screw 7.

[0038] The lens mounting plate 4 is provided with two clamps 10, which are used to support and fix the infrared lens, facilitating the rapid expansion and installation of the lens on the lens mounting plate 4.

[0039] Multiple guide rods 11 are provided in the second slide groove 3. The detector fixing seat 5 is slidably connected to the multiple guide rods 11. The guide rods 11 guide the sliding of the detector fixing seat 5 in the second slide groove 3, ensuring that the detector fixing seat 5 can slide stably.

[0040] A knob 12 is provided at one end of the bidirectional lead screw 7 and at one end of the unidirectional lead screw 9. The two knobs 12 are located on the same side of the cooler fixing plate 8. The knobs 12 can be easily held and rotated.

[0041] The inner walls of the first slide groove 2 and the third slide groove 6 are provided with limiting grooves 13. The opposite sides of the lens fixing plate 4 and the opposite sides of the cooler fixing plate 8 are provided with limiting strips 14. The limiting strips 14 are inserted into the corresponding limiting grooves 13. The limiting grooves 13 have a guiding and supporting effect on the sliding of the limiting strips 14, thereby ensuring that the lens fixing plate 4 slides stably in the first slide groove 2 and the cooler fixing plate 8 slides stably in the third slide groove 6.

[0042] Working principle: First, the lens is fixed on the lens mounting plate 4, the clamp 10 fixes the lens, the detector is fixed on the detector mounting base 5, and the cooler is fixed on the cooler mounting plate 8. The detector connects to the lens and the cooler. Second, when a module needs to be inspected or maintained, simply disassemble the connection between the detector, lens, and cooler, hold the knob 12 and rotate the bidirectional lead screw 7. Since the positive and negative threads of the bidirectional lead screw 7 are screwed to the lens mounting plate 4 and the detector mounting base 5 respectively, the thread action of the bidirectional lead screw 7 causes the lens mounting plate 4 to slide in the first slide groove 2. At this time, the lens mounting plate 4... The limiting strip 14 on the upper slides within the limiting groove 13 of the first slide 2, and the detector mounting base 5 slides within the second slide 3. At this time, the detector mounting base 5 also slides along multiple guide rods 11, thereby achieving positional separation between the lens and the detector. Next, the knob 12 is held and the one-way screw 9 is rotated. The thread of the one-way screw 9 causes the cooler mounting plate 8 to slide within the third slide 6. At this time, the limiting strip 14 on the cooler mounting plate 8 slides along the limiting groove 13 of the third slide 6, thereby achieving separation between the detector and the cooler. Finally, the modules that need to be inspected and maintained can be disassembled individually.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
