Technical Field

[0001] This utility model relates to the field of testing fixture technology, specifically a testing fixture for the button feel and response sensitivity of a video guide instrument. Background Technology

[0002] The button feel and response sensitivity testing fixture for video guidance devices is a specialized testing equipment. It objectively and quantitatively evaluates the button's pressing force (feel) and trigger reliability (sensitivity) by simulating human hand pressing actions. This type of fixture typically consists of a precision mechanical structure (such as a servo motor or cylinder providing pressing power), high-precision sensors (such as pressure sensors and displacement sensors), and an automatic control system. It can accurately measure parameters such as button pressing force, travel, and rebound force, and generate detailed force-displacement curves for analysis, thereby replacing subjective human judgment and ensuring product quality consistency and reliability.

[0003] However, existing testing fixtures are not easy to adjust the angle during press testing, resulting in blind spots in sensitivity testing. Therefore, those skilled in the art provide a testing fixture for the button feel and response sensitivity of a video guide to solve the problems mentioned in the background art.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3This utility model provides a testing fixture for the button feel and response sensitivity of a video guide, including a testing fixture mounting plate 1, a testing fixture connecting seat 2 fixed at the bottom of the testing fixture mounting plate 1, a lifting testing mechanism 3 installed at the top of the testing fixture connecting seat 2, a rotating platform 4 rotatably connected to the top of the testing fixture mounting plate 1 via a rotating shaft, a bearing bracket 5 fixed at the top of the rotating platform 4, a quick adjustment module 6 provided at the top of the testing fixture mounting plate 1, a material placement housing 7 fixed to the outside of the testing fixture connecting seat 2, a detection line 8 connected to one side of the material placement housing 7, and an anti-loosening mechanism 9 provided on the outside of the material placement housing 7; The quick-adjustment module 6 includes a main fixed housing 61, which serves for installation and protection. A base connecting gasket 62 is fixed to the inner bottom wall of the main fixed housing 61, providing connection and reinforcement. A return spring 63 is located on the top of the base connecting gasket 62, providing elastic force. A movable contact pad 64 is connected to the top of the return spring 63. A buffer limiting pad 65 is fixed to the top of the movable contact pad 64. A support column 66 is located on the top of the buffer limiting pad 65. A non-slip connecting pad 67 is fixed at the top, a hand grip 68 is provided on one side of the buffer limiting pad 65, a through groove 69 is provided inside the main fixed housing 61, an auxiliary mounting bracket 610 is fixed at the bottom of the buffer limiting pad 65, a guide roller 611 is rotatably connected to the outside of the auxiliary mounting bracket 610 via a rotating shaft, the main fixed housing 61 and the test fixture mounting plate 1 are fixedly connected, the upper top surface of the non-slip connecting pad 67 is in contact with the lower bottom surface of the rotating platform 4, the size of the through groove 69 is adapted to the size of the hand grip 68, and the outside of the hand grip 68 is provided with non-slip texture.

[0015] During use, when testing the button feel and response sensitivity of the video guide, the video guide is placed on top of the support bracket 5. The operator moves the hand grip 68 outward, causing the buffer limit pad 65 and the movable contact pad 64 to compress the return spring 63, causing the anti-slip connecting pad 67 to disengage from the bottom of the rotating platform 4 and release the locked state. At this time, the rotating platform 4 can rotate freely, allowing the video guide on the support bracket 5 to be adjusted to the optimal test angle. After releasing the hand grip 68, the return spring 63 pushes the movable contact pad 64 back to its original position, and the anti-slip connecting pad 67 re-attaches tightly to the bottom of the rotating platform 4, instantly locking the angle using friction. This design avoids the cumbersome operation of traditional bolt fixing methods, significantly shortens the angle adjustment time, and the cooperation of the buffer limit pad 65 and the anti-slip connecting pad 67 can effectively prevent rigid impacts during the adjustment process, protecting the structural integrity of the equipment. The overall module, through mechanical linkage and elastic element collaboration, is especially suitable for repetitive testing scenarios that require frequent angle adjustments, achieving the goal of easy and quick adjustment of the video guide's placement and testing angle. The button feel and response sensitivity of the video guide are then tested through the lifting test mechanism 3.

[0016] Please see Figure 1 and Figure 4 This utility model provides a testing fixture for the button feel and response sensitivity of a video guidance device. The anti-loosening mechanism 9 includes a sealed housing 91, which serves as an external installation protection. A reinforcing connecting block 92 is fixed to the outside of the sealed housing 91, which serves as a reinforcement connection. An elastic protective sleeve 93 is rotatably connected to the inside of the sealed housing 91 via a rotating shaft. One end of the elastic protective sleeve 93 is rotatably connected to a movable pressure plate 94 via a rotating shaft. One end of the movable pressure plate 94 is connected to a tension spring 95. A sliding guide is fixed to one side of the movable pressure plate 94. Block 96, the sliding guide block 96 plays the role of guiding the movement, the inside of the sealed housing 91 is provided with a guide groove 97, the outside of the movable pressure plate 94 is fixed with a handle block 98, the outside of the sealed housing 91 is provided with a through hole, and the size of the through hole is adapted to the size of the detection line 8, the reinforcing connecting block 92 is embedded and fixed inside the material placement housing 7, the sliding guide block 96 and the guide groove 97 are sliding fit components, one end of the tension spring 95 is embedded and fixed inside the sealed housing 91, and the outside of the sealed housing 91 is provided with a through groove to accommodate the movement of the handle block 98.

[0017] During use, after the detection line 8 passes through the through hole of the sealed housing 91 and connects to the material placement housing 7, the operator pulls the handle block 98, which drives the movable pressure plate 94 to compress the tension spring 95. The sliding guide block 96 slides along the guide groove 97 to ensure accurate movement trajectory. At this time, the elastic protective sleeve 93 is stretched, forming an opening space for the line to be placed. After releasing the handle block 98, the tension spring 95 rebounds, driving the movable pressure plate 94 to press the elastic protective sleeve 93 tightly, so that its inner wall evenly wraps the outer side of the detection line 8. Three-dimensional fixation is achieved through a combination of flexibility and rigidity. This structure can not only offset the displacement caused by the vibration of the line itself or accidental pulling, but also avoid wear on the line skin through the buffering characteristics of the elastic protective sleeve 93. The cooperation between the guide groove 97 and the sliding guide block 96 eliminates the risk of pressure plate deflection, and the design of the sealed housing 91 has the functions of dustproof and anti-accidental contact. This mechanism is especially suitable for long-term high-frequency testing environments.

[0018] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
