Flexible connection device and connection method of a test device and an optical sighting device

Abstract

This invention discloses a flexible connection device and method for connecting a testing device and an optical aiming device. It solves the problem in existing technologies where the tested optical aiming device has a small contact surface, other areas cannot be contacted, and the surrounding space is limited, making it impossible to connect the testing device to the outer shell of the optical aiming device. In this invention, a flexible restraint strap is used to fix the test object (the tested optical aiming device) by wrapping and locking it around. The thickness of the flexible restraint strap is ≤1mm, and the width is only 10-13mm. Therefore, fixation can be achieved by finding only a local surface on the outer shell of the test object (the tested optical aiming device), without requiring a complete clamping surface. This structural feature directly solves the technical problem of "small contact surface" and overcomes the technical bias of existing technologies that "require a large area of ​​clamping."

Description

Technical Field

[0001] This invention relates to a connection device and method for optical equipment, and more specifically to a flexible connection device and method for a test device and an optical aiming device. Background Technology

[0002] In the performance testing of optical aiming equipment (such as sights, observation devices, etc.), it is often necessary to fix the testing equipment (such as optical calibrators, parameter testing modules, etc.) on the shell of the equipment under test in order to test the accuracy of the aiming line, optical parameters and other indicators.

[0003] In existing technologies, the connection between the testing equipment and the optical device under test is usually achieved using clamps or special tooling, which mainly presents the following technical problems:

[0004] 1. Limited contact area makes traditional clamps difficult to install. The housing of the optical aiming device under test usually only has a localized contact area (such as a small section of the curved surface of the lens barrel), while other areas are inaccessible due to optical windows, adjustment knobs, interfaces, etc. Existing clamp designs often require a large clamping area or a complete clamping surface, thus failing to meet the constraint of "only partially accessible" in most cases.

[0005] 2. Limited surrounding space prevents the deployment of large tooling. When testing optical aiming equipment in its entirety on a vehicle or machine, it is often surrounded by other components, resulting in extremely limited operating space. Existing rigid clamps and slot-type tooling are typically large in size, requiring significant operating space for installation and disassembly, making them unsuitable for use in confined spaces.

[0006] 3. Traditional connection methods carry the risk of damage. For optical devices without pre-reserved clamping interfaces, drilling, bonding, or custom-made slots are commonly used to connect the test equipment. However, drilling can damage the device structure, affecting sealing and optical reference; bonding leaves residual adhesive that contaminates the optical surface, and its reliability is insufficient under high temperature and vibration environments; custom-made slots require design for specific models, which is costly, time-consuming, and the space occupied by the slot itself often exceeds the capacity of confined spaces.

[0007] 4. Existing technologies suffer from a technical bias of "requiring large-area clamping." A search reveals that existing clamping patents primarily address the single problem of "how to clamp an object," and generally exhibit a technical bias: they assume that only large-area clamping clamps, complete clamping surfaces, or rigid slots can achieve reliable positioning and fixation of the equipment. When the optical aiming device under test is in a fully assembled state, and only a local curved surface is available for connection, existing technologies cannot simultaneously satisfy the three combined constraints of "small contact area," "confined space," and "non-destructive connection."

[0008] The patent documents related to this technical solution mainly fall into the following categories:

[0009] (1) Patents related to testing devices for photoelectric aiming systems. For example, Chinese patent CN105547049A discloses a downward-looking tracking testing device for a photoelectric aiming system. It uses a two-dimensional turntable to drive the movement of a collimator for testing. The testing equipment and the aiming system under test are fixed to the frame by rigid mounting components. This type of device uses a rigid connection method, which usually requires a dedicated mounting interface and a large installation space, making it difficult to apply in testing scenarios where the available contact surface is small and the surrounding space is confined.

[0010] (2) Patents related to verification devices for modular optical aiming systems. For example, US Patent 10783111B2 discloses a peripheral module verification device for a modular digital optical aiming system. This device connects to the aiming system module via a data connector to achieve data format conversion and functional verification. This type of device relies on the standardized data interface (such as RS232, USB, etc.) reserved by the aiming system, and belongs to the verification at the electrical connection and data communication level. It cannot solve the problem of fixing the test equipment when there is no reserved physical interface.

[0011] (3) Patents on flexible restraint / bundling devices. Flexible restraint straps have been widely used in the field of item bundling. For example, European patent EP0240036A2 discloses a bundling device with a locking head and a toothed strap. This type of device adopts the basic principle of "flexible strap + locking structure" and is mainly used in general bundling scenarios such as wire harness bundling and item wrapping. Its core function is to bind multiple objects together. It mainly focuses on the reliability of bundling, and positional accuracy is not a design consideration. Moreover, there is usually no constraint of touching sensitive areas during operation. In contrast, this invention applies the flexible restraint component to the fixed scenario of test equipment for optical aiming equipment. It needs to be installed under the constraint of a small contact surface and a narrow surrounding space without touching sensitive areas such as optical windows and adjustment knobs, and maintain sub-millimeter-level positional stability between the test equipment and the test equipment under vibration. The two have significant differences in application fields, technical problems to be solved, and technical effects. Summary of the Invention

[0012] The purpose of this invention is to solve the technical problem in the prior art that the test equipment is often difficult to connect to the housing of the optical aiming device because the contact surface of the optical aiming device under test is small, the other positions cannot be contacted, and the surrounding space is narrow. The invention provides a flexible connection device and connection method between the test equipment and the optical aiming device.

[0013] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0014] A flexible connection device for a testing device and an optical aiming device is characterized by comprising: an adapter plate, multiple pairs of restraint components disposed on two opposite edges of the adapter plate, and multiple flexible restraint straps disposed between each pair of restraint components, wherein the multiple flexible restraint straps are used to fix the test sample to the adapter plate.

[0015] Each of the aforementioned restraint components includes: a positioning block, a first pressure block, a vertical locking structure, a horizontal locking structure, and a second pressure block; the second pressure block and the positioning block are sequentially and correspondingly arranged on the same side edge of the adapter plate from the outside to the inside, wherein the positioning block is fixedly arranged on the adapter plate, and the second pressure block abuts against the adapter plate and can slide along the surface of the adapter plate; the horizontal locking structure connects the second pressure block and the positioning block in the horizontal direction to form a horizontal fixing component; the vertical locking structure is sequentially connected from top to bottom to the first pressure block and the second pressure block, so that the first pressure block and the second pressure block form a vertical fixing clamping structure;

[0016] Each of the flexible restraint straps has its two ends respectively set in two vertical fixing clamping structures on two opposite sides of the adapter plate.

[0017] Furthermore, the restraint assembly also includes multiple limiting rings;

[0018] Multiple limiting rings are respectively disposed between two corresponding positioning blocks and the first pressure block, and are respectively connected to both ends of the flexible restraint strap; used to fix the ends of the flexible restraint strap that pass through the vertical fixing clamping structure.

[0019] Furthermore, both the vertical locking structure and the horizontal locking structure are screws.

[0020] Furthermore, the positioning block is fixedly connected to the adapter plate by bolts.

[0021] Furthermore, the adapter plate has multiple bolt holes for connecting testing equipment.

[0022] Furthermore, the side of the adapter plate facing away from the restraint assembly has a shape adapted to the contact surface shape of the test specimen, for fitting against the contact surface of the test specimen.

[0023] Furthermore, it also includes silicone rubber pads;

[0024] The silicone rubber pad is disposed on the side of the adapter plate opposite to the restraint assembly, located between the adapter plate and the test sample.

[0025] Furthermore, the thickness of the flexible restraint band is less than 1 mm, and the width is 10-13 mm;

[0026] The adapter plate is a metal plate.

[0027] A flexible connection method between a testing device and an optical aiming device, characterized in that it employs the aforementioned flexible connection device for the testing device and the optical aiming device, and includes the following steps:

[0028] Step 1: Connect the test specimen to the side of the adapter plate that is opposite to the restraint assembly, and restrain it with multiple flexible restraint straps. Clamp the two ends of each flexible restraint strap in two vertical fixing clamping structures on the two opposite edges of the adapter plate.

[0029] Step 2: Loosen the vertical locking structure at one end of each flexible restraint strap in turn, tighten the flexible restraint strap from that end, and secure it through the corresponding vertical locking structure.

[0030] Step 3: By adjusting the transverse locking structure, the flexible restraint strap is tightened step by step, thereby fixing the test subject on the side of the adapter plate facing away from the restraint assembly.

[0031] Step 4: Securely connect the test equipment to the side of the adapter plate that connects to the restraint assembly to complete the connection between the test equipment and the test sample.

[0032] Further, step 1 specifically involves: connecting the test specimen to the side of the adapter plate facing away from the restraint assembly, restraining it with multiple flexible restraint straps, and passing both ends of each flexible restraint strap through two vertical fixing clamping structures and limiting rings on the two opposite edges of the adapter plate, and then passing them back through the vertical fixing clamping structures.

[0033] Compared with the prior art, the present invention has the following beneficial technical effects:

[0034] 1. This invention provides a flexible connection device for a testing device and an optical aiming device. The device uses a flexible restraint strap to secure the test object (the optical aiming device under test) by wrapping and locking it around. The flexible restraint strap can be ≤1mm thick and only 10-13mm wide. Therefore, only a local surface on the outer shell of the test object (optical aiming device under test) is needed for fixation, eliminating the need for a complete clamping surface. This structural feature directly solves the technical problem of "small available contact surface" and overcomes the technical bias of existing technologies that require "large-area clamping."

[0035] 2. The present invention provides a flexible connection device for testing equipment and optical aiming equipment. Because the flexible restraint band has the characteristics of flexibility and bendability, the wrapping and tightening actions can be completed with only one hand during operation, without the need for a large operating space, thus solving the technical problem of "limited surrounding space".

[0036] 3. The present invention provides a flexible connection device for testing equipment and optical aiming equipment, which eliminates the need for drilling, bonding or designing special slots on the shell of the test object (optical aiming equipment under test). Through the tightening of the flexible binding strap and the protection of the silicone rubber pad, no indentations, scratches or contamination will be caused to the surface of the shell of the test object (optical aiming equipment under test), thus achieving a zero-damage connection for precision optical equipment.

[0037] 4. This invention provides a flexible connection device between a testing device and an optical aiming device. The length of the flexible restraint strap can be cut on-site according to different models of the device under test, and the installation position of the positioning block can also be flexibly adjusted according to the fixable area on the adapter plate. It can adapt to a variety of optical aiming devices of different shapes and sizes, without the need to design tooling separately for each model. This invention also has the advantages of quick assembly and disassembly, no damage to the test object (the optical aiming device under test), multiple reuses, and effective reduction of testing costs and cycle time.

[0038] 5. The present invention provides a flexible connection device and method for connecting a testing device and an optical aiming device. Through a step-by-step tightening mechanism with a lateral locking structure, the tensile force can be precisely controlled, avoiding excessive tightness or looseness. Simultaneously, the adapter plate and flexible restraint strap, via a first pressure block, a second pressure block, and a limiting ring, uniformly transmit the tightening force to the adapter plate, establishing a stable and fixed connection between the testing device and the test object (the optical aiming device under test). Experimental verification shows that under typical vibration conditions, the relative displacement between the testing device and the test object (the optical aiming device under test) can be controlled within 0.05 mm, fully meeting the requirements for maintaining relative position in high-precision optical testing.

[0044] To make the objectives, advantages, and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0045] This embodiment provides a flexible connection device for testing equipment and optical aiming equipment. By using a high-strength, thin-walled flexible restraint strap 4 for a surrounding locking method, the adapter plate 2 and the testing equipment can be fixed to the test object (optical aiming equipment) shell without damage and stably using only a local arc surface of about 10-13mm wide on the test object (optical aiming equipment). At the same time, by utilizing the bendability and thinness of the flexible restraint strap 4, it is possible to quickly install and remove the device with one hand in a small space around the whole vehicle or machine, thereby overcoming the technical prejudice in the prior art that "large area clamping is required".

[0046] The flexible connection device in this embodiment, such as Figure 1 and Figure 2 As shown, the device includes: multiple pairs of restraint components 1, an adapter plate 2, and multiple flexible restraint straps 4. The multiple pairs of restraint components 1 are symmetrically arranged on opposite edges of the adapter plate 2. Each flexible restraint strap 4 is positioned between each pair of restraint components 1, extending naturally along the side of the adapter plate 2 opposite to the multiple pairs of restraint components 1. In use, the test object (the optical aiming device under test) is fixed to the adapter plate 2 by wrapping and locking the flexible restraint straps 4 around it. The thickness of the flexible restraint straps used is ≤1mm, and the width is only 10-13mm. Therefore, only a local surface on the outer shell of the test object 3 (the optical aiming device under test) is needed for fixation, without requiring a complete clamping surface. This structural feature directly solves the technical problem of "small available contact surface" and overcomes the technical bias of existing technologies that "must clamp over a large area."

[0047] like Figure 3As shown, in this embodiment, the restraint assembly 1 includes: a positioning block 1-1, a first pressing block 1-2, a vertical locking structure 1-3, a horizontal locking structure 1-4, a second pressing block 1-5, and a limiting ring 1-6. The positioning block 1-1 is fixedly mounted on the adapter plate 2, and the second pressing block 1-5 abuts against the adapter plate 2 and can slide along the surface of the adapter plate 2. The horizontal locking structure 1-4 horizontally connects the second pressing block 1-5 and the positioning block 1-1 to form a horizontal fixing assembly. The first pressing block 1-2 is mounted on the second pressing block 1-5 and connected by the vertical locking structure 1-3 to form a vertical fixing clamping structure. The two ends of the flexible restraint band 4 are respectively disposed within the vertical fixing clamping structures on opposite edges of the adapter plate 2. The limiting ring 1-6 is disposed between the positioning block 1-1 and the first pressing block 1-2; it is used to fix the ends of the flexible restraint band 4 that pass through the vertical fixing clamping structure. The lateral fixing component ensures the horizontal stability of the flexible restraint strap 4 under tension and enables step-by-step tightening in the horizontal direction, allowing precise control of the tension and preventing it from being too tight or too loose. Simultaneously, the adapter plate 2 and the flexible restraint strap 4 are connected by the first pressure block 1-2, the second pressure block 1-5, and the limiting ring 1-6, which evenly transmit the tightening force to the adapter plate 2, creating a stable connection between the testing equipment and the test object (the optical aiming device under test).

[0048] The length of the flexible restraint strap 4 can be cut on-site according to different models of test specimens (optical aiming devices under test), and the installation position of the positioning block 1-1 can also be flexibly adjusted according to the fixable area on the adapter plate 2. Therefore, the device in this embodiment can be adapted to a variety of test specimens (optical aiming devices under test) of different shapes and sizes, without the need to design tooling separately for each model.

[0049] In this embodiment, both the vertical locking structure 1-3 and the horizontal locking structure 1-4 are screws, which can achieve step-by-step adjustment.

[0050] The positioning block 1-1 is bolted to the adapter plate 2, which enables quick disassembly and installation of the positioning block 1-1.

[0051] The adapter plate 2 has multiple bolt holes for connecting test equipment.

[0052] A silicone rubber pad is placed between the adapter plate 2 and the test sample 3. The silicone rubber pad can protect the test sample 3 and will not cause any indentation, scratches or contamination to the surface of the test sample shell, thus achieving zero-damage connection of precision optical equipment.

[0053] This embodiment also provides a flexible connection method between a testing device and an optical aiming device, including the following steps:

[0054] Step 1: Connect the two ends of the flexible restraint band 4 to the limiting rings 1-6 respectively, connect the side of the adapter plate 2 facing away from the multiple pairs of restraint components 1 to the test sample 3, and restrain it through multiple flexible restraint bands 4.

[0055] Step 2: Tighten the flexible restraint straps 4 in sequence and secure them with the vertical locking structures 1-3;

[0056] Step 3: Fix the test equipment to the side of the adapter plate 2 that is connected to the restraint component 1 to complete the connection between the test equipment and the test sample 3.

[0057] The following verification was performed on the flexible connection device and connection method between the test equipment and the optical aiming equipment in this embodiment:

[0058] Test sample 3 was set as the scope barrel of the aiming scope. The only area that could be touched on its outer shell was a local arc surface with a width of about 10-13mm. The other parts could not be touched because of the optical window, adjustment knob, etc.

[0059] The upper surface of adapter plate 2 is fixed with an optical calibrator, and the lower surface contour of adapter plate 2 matches the contact arc surface (partial arc surface) of the scope barrel. Adapter plate 2 is made of aluminum alloy, ensuring sufficient strength while also being lightweight. Multiple threaded holes are pre-drilled on the upper surface of adapter plate 2 for connecting to different models of testing equipment.

[0060] The flexible restraint strap 4 is made of high-strength aramid fiber woven tape with a thickness of 0.8mm and a width of 12mm.

[0061] During installation, first place the adapter plate 2 on the contact arc surface of the scope barrel, with a 1mm thick silicone rubber pad between them to protect the surface of the test object and increase friction. Then, wrap the flexible restraint strap 4 around the outer shell of the scope barrel, passing both ends of the flexible restraint strap 4 through the limiting rings 1-6, folding it in half, and passing it through the first pressure block 1-2 and the second pressure block 1-5 respectively. Finally, gradually tighten the flexible restraint strap 4 through the transverse locking structure 1-4 until a stable connection is formed between the adapter plate 2 and the scope barrel. The transverse locking structure 1-4 uses a threaded step tightening mechanism, which can precisely control the tension and avoid damage to the scope barrel due to excessive tightening.

[0062] The optical calibrator is fixed with screws through the reserved holes on the upper surface of the adapter plate 2. At this time, a stable relative position relationship is formed between the optical calibrator and the scope barrel. Experimental verification shows that under typical vibration environment, the relative displacement between the test equipment (optical calibrator) and the test object (scope barrel) can be controlled within 0.05mm, which fully meets the requirements of high-precision optical testing for maintaining relative position.

[0063] Furthermore, in this embodiment, the test specimen 3 can have an irregular, non-standard shape with only local protrusions for contact. In this case, a longer flexible restraint strap 4 can be used, cut to a suitable length on-site according to the actual restraint location. The installation position of the positioning block 1-1 is also adjusted accordingly based on the fixable area on the adapter plate 2. The number of restraint components 1 can be set to two or more pairs according to the required tensile force, evenly arranged along the circumference of the test specimen 3 to ensure balanced force distribution. The remaining structure and installation method are the same as the connection method of the scope barrel described above.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present invention.
