Description

Technical Field

[0001] This utility model relates to the field of scratch detection technology, specifically to a scratch detection device for air conditioning vents. Background Technology

[0002] A scratch detection device is a device or system used to detect whether scratches have occurred on the surface of an object and to obtain related information. However, existing scratch detection devices have some shortcomings, such as:

[0003] The scratch resistance testing device and method for an automotive sub-dashboard, as described in application number CN202010377428.3, suffers from inaccurate experimental results because the device lacks a scratch force adjustment function, resulting in a limited scratch effect that cannot fully simulate the real environment. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioner vent scraping detection device to solve the problem mentioned in the background art that the existing equipment on the market does not have a scraping force adjustment function, which leads to the equipment having a single scraping effect, failing to fully simulate the real environment, and resulting in inaccurate experimental results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner vent scraping detection device, comprising a detection host, a control panel, a friction head, a gasket, and a push cover;

[0006] The detection host is provided with a drive mechanism on its side. The drive mechanism includes a first link, a motor, a second link, and a drive plate. The first link and the second link convert the circular motion into linear motion under the drive of the motor, thereby driving the drive plate to reciprocate.

[0007] The drive plate is provided with a scraping mechanism on its side. The scraping mechanism includes a friction head, a spring, a push rod, a limit buckle, a limit groove, a threaded fixing rod, a magnetic ring, and a push cover. The push cover is fixed to different positions of the threaded fixing rod by the limit buckle, thereby applying different forces to the friction head and achieving different scraping effects.

[0008] As a preferred technical solution of this utility model, the detection host is generally trapezoidal in structure, and a rectangular groove is opened at the center of the detection host for placing the scraping mechanism. The control screen is fixedly connected at the center of the side of the detection host, and four pads are evenly fixed on the bottom surface of the detection host.

[0009] By adopting the above technical solution, the device can be more ergonomic by making the detection host a trapezoidal structure, which makes it easier to operate and observe. The four pads evenly fixed on the bottom of the detection host can play a role in buffering and shock absorption.

[0010] As a preferred technical solution of this utility model, the detection host is slidably connected to the side of the drive plate, the drive plate is rotatably connected to the side of the first link, the first link is rotatably connected to the bottom of the second link, the second link is rotatably connected to the bottom of the motor, and the motor output shaft is fixed to the eccentric disk;

[0011] Using the above technical solution, the device can convert circular motion into reciprocating motion through an eccentric disk fixed to the motor output shaft, thereby driving the drive plate to achieve scraping operation.

[0012] As a preferred technical solution of this utility model, the drive plate is fixedly connected to a threaded fixing rod on the side. Eight limiting grooves are evenly opened on the surface of the threaded fixing rod, and the inside of the threaded fixing rod is a hollow structure. The outer ring of the threaded fixing rod is threadedly connected to the push cover. The surface of the push cover is provided with anti-slip texture, and a magnetic ring is fixedly connected to the side of the push cover. A limiting buckle is hinged on the top of the push cover, and the limiting buckle is made of iron.

[0013] Using the above technical solution, the device will directly engage with the magnetic ring through the limit buckle, thus fixing the push cover in place.

[0014] As a preferred embodiment of this utility model, the threaded fixing rod is slidably connected to the push rod on its side, the push rod is fitted with a spring on its side, the left side of the push rod has a tapered structure, and the push rod is fixedly connected to one end of the spring. The push rod is threadedly connected to a friction head on its side.

[0015] By adopting the above technical solution, the device can provide different magnitudes of force to the push rod under the action of the spring by fixing the push cover at different positions of the threaded fixing rod, thus pushing the friction head outward. The friction head is threadedly connected to the push rod, which can improve the convenience of replacing the friction head.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The scraping force can be flexibly adjusted. By changing the position of the push cover on the threaded fixing rod, the pressure applied by the friction head to the air conditioner outlet can be precisely controlled to simulate different degrees of scraping and improve the accuracy of the test results.

[0018] 2. The adjustable speed motor enables the testing device to simulate various usage scenarios. Different usage frequencies correspond to different scraping speeds, thereby more comprehensively testing the scraping performance of the air conditioning vent in actual use and providing more reliable data support for product quality assessment.

[0026] 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.

[0027] Please see Figures 1-6 The present invention provides a device for detecting scratches on an air conditioner vent, comprising a detection host 1, a control panel 2, a friction head 3, a gasket 4, a first connecting rod 5, a motor 6, a second connecting rod 7, a drive plate 8, a spring 9, a push rod 10, a limit buckle 11, a limit groove 12, a threaded fixing rod 13, a magnetic ring 14, and a push cover 15.

[0028] The detection host 1 has a trapezoidal structure, which conforms to the ergonomic principle and makes it convenient for operators to operate and observe. A rectangular groove is provided at the center line of the detection host 1 to house the scraping mechanism. The control panel 2 is fixedly connected to the center line of the side of the detection host 1, which allows operators to control the device and view relevant data. In addition, four pads 4 are evenly fixed on the bottom surface of the detection host 1. These pads 4 can play a role in buffering and shock absorption, reducing the vibration of the device during operation and ensuring the accuracy of detection.

[0029] The drive mechanism is located on the side of the detection host 1. It mainly consists of a first connecting rod 5, a motor 6, a second connecting rod 7, and a drive plate 8. An eccentric disk is fixed on the output shaft of the motor 6. After the motor 6 is started, the eccentric disk rotates, driving the first connecting rod 5 to perform circular motion. The second connecting rod 7 is rotatably connected below the first connecting rod 5, and the motor 6 is rotatably connected below the second connecting rod 7. This structural design enables the first connecting rod 5 and the second connecting rod 7 to convert circular motion into linear motion under the drive of the motor 6, thereby driving the drive plate 8 to perform reciprocating motion.

[0030] The scraping mechanism is located on the side of the drive plate 8. It includes a friction head 3, a spring 9, a push rod 10, a limit buckle 11, a limit groove 12, a threaded fixing rod 13, a magnetic ring 14, and a push cover 15. The threaded fixing rod 13 is fixedly connected to the side of the drive plate 8. Eight limit grooves 12 are evenly distributed on the surface of the threaded fixing rod 13, and its interior is hollow. The outer ring of the threaded fixing rod 13 is threadedly connected to the push cover 15. The surface of the push cover 15 is provided with anti-slip texture for easy operation. The magnetic ring 14 is fixedly connected to the side of the push cover 15, and the limit buckle 11 is hinged to the top. The limit buckle 11 is made of iron. When the position of the push cover 15 on the threaded fixing rod 13 is adjusted, the limit buckle 11... Under the action of the magnetic ring 14, it will directly engage with the limiting groove 12 of the threaded fixing rod 13, thereby fixing the push cover 15. The threaded fixing rod 13 is slidably connected to the push rod 10 on the side. The push rod 10 is fitted with a spring 9 on the side. The left side of the push rod 10 has a tapered structure and is fixedly connected to one end of the spring 9. The friction head 3 is threadedly connected to the side of the push rod 10. By fixing the push cover 15 at different positions on the threaded fixing rod 13, the spring 9 can provide different magnitudes of force to the push rod 10, thereby pushing the friction head 3 outwards by different distances to achieve different scraping effects. At the same time, the friction head 3 is threadedly connected to the push rod 10, making the replacement of the friction head 3 more convenient.

[0031] Working principle: When using an air conditioner vent scraping detection device, before use, the speed of motor 6 is set through the control panel 2 according to the detection requirements. For example, if it is necessary to simulate a frequent use scenario, the speed of motor 6 can be increased; if it is necessary to simulate a less frequent use scenario, the speed can be decreased.

[0032] Then adjust the scraping force of the friction head 3; twist the push cover 15 to move the push cover 15 on the threaded fixing rod 13. When it moves to the appropriate position, rotate the limit buckle 11 to make it lock into the corresponding limit groove 12. The magnetic ring 14 will fix the limit buckle 11 and the limit groove 12 to prevent the push cover 15 from loosening during the detection process. The change in the position of the push cover 15 will compress or relax the spring 9, thereby changing the thrust on the push rod 10, and finally adjusting the pressure of the friction head 3 on the air conditioner outlet.

[0033] Place the testing device in a suitable position on the fixed test piece. The pad 4 acts as a buffer and stabilizing device. Start the motor 6. The output shaft of the motor 6 drives the eccentric disk to rotate. The eccentric disk drives the first connecting rod 5 to make a circular motion. The first connecting rod 5 converts the circular motion into the linear reciprocating motion of the drive plate 8 through the second connecting rod 7. The drive plate 8 drives the scraping mechanism to move. The friction head 3 performs scraping detection on the surface of the air conditioner outlet. During the detection process, the operating status of the motor 6 and the detection time and other parameters can be observed in real time through the control screen 2.

[0034] After the test is completed, turn off motor 6, screw the push cover 15 back to the initial position, remove the test device, observe and analyze the surface of the air conditioner vent, and evaluate the scratch performance of the air conditioner vent based on the depth and width of the scratch marks and the surface damage.

[0035] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
