Description

Technical Field

[0001] This utility model relates to the field of paint scratch detection technology, and in particular to a structure for detecting the scratch resistance of furniture paint layers. Background Technology

[0002] Furniture coating refers to one or more layers of coating applied to the surface of furniture. Its main purpose is to protect the furniture surface and enhance its aesthetics, durability, and corrosion resistance. The coating can prevent furniture from being damaged by ultraviolet rays, moisture, chemicals, etc., and can also cover up the defects of the wood and improve the overall texture of the furniture.

[0003] Scratch resistance testing can evaluate the abrasion resistance of coating layers. For example, Chinese Patent Publication No. CN211122384U discloses a scratch resistance testing device for metal surface coatings, specifically relating to the field of scratch resistance testing devices. It includes a base, a gantry frame on top of the base, a groove on the top of the base, a slide rail fixedly installed inside the groove, a platform on top of the slide rail, a scraping mechanism on top of the gantry frame, and a fixing mechanism on top of the platform. The fixing mechanism includes a stud fixedly installed on top of the platform, and a pressure block and a clamping nut movably fitted on the rod wall of the stud. This invention, by setting up a scraping mechanism, allows the scraping head to be threaded onto a connecting rod during testing, facilitating its removal and storage and preventing damage. The weights are magnetically attached to the magnetic head, greatly simplifying the loading and unloading of weights and improving worker efficiency and the practicality of the device.

[0004] In practice, the test sample is clamped by tightening the bolts and using the pressure block. However, whether fixing or unlocking the sample, the reciprocating rotation of the bolts affects the loading and unloading efficiency of the sample. The inability to clamp the sample quickly and easily results in slow testing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to conveniently and quickly clamp templates, and to propose a scratch resistance testing structure for furniture coating layers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a scratch resistance testing structure for furniture coating layers, including a testing platform, a testing unit and a delivery unit on the top of the testing platform, the delivery unit including a tray and a fixing component on the tray, the tray being connected to a drive unit inside the testing platform for transporting test samples;

[0008] The fixing component includes a stop member and an unlocking member. A stop component is provided between the stop member and the unlocking member. The stop component is used to fix the unlocking member so as to drive the stop member to press the test sample.

[0009] Furthermore, the fixing component also includes a bracket, which is fixedly connected to the top of the tray. The abutment is rotatably connected to the side of the bracket via a rotating seat. The abutment has an L-shaped structure and the unlocking component is located at its top.

[0010] Furthermore, the bottom of the unlocking component has a circular structure, and its top extends outward to form a push rod. The unlocking component is rotatably connected to the top groove of the abutment component via an eccentric shaft, and the unlocking component abuts against the bracket through eccentric rotation.

[0011] Furthermore, the stop assembly includes a connecting part, which is fixedly connected to the side of the abutment member. A stop rod is slidably connected inside the connecting part, and a stepped groove is provided. A limiting part is provided at the top of the stop rod, and a spring is sleeved around the limiting part between the limiting part and the stepped groove.

[0012] Furthermore, it also includes a gear, which is fixedly connected to the end of the eccentric shaft. The limiting part is engaged with the tooth groove of the gear by a limiting protrusion at the top, and a guide slope that slides against the gear is provided on one side of the limiting protrusion.

[0013] Furthermore, the bottom of the abutment is provided with a push handle, and the side of the rotating seat is provided with a clearance groove to avoid the push handle.

[0014] The present invention proposes a scratch resistance testing structure for furniture coatings, which has the following advantages: The present invention achieves convenient clamping of the test sample by rotating the unlocking component to drive the abutment component to press against the test sample. During the rotation of the unlocking component, the eccentric shaft at its bottom rotates synchronously, and the eccentric shaft and the abutment component rotate in one direction through the stop assembly. Therefore, after the unlocking component drives the abutment component to clamp, it can prevent the unlocking component from rotating due to accidental operation or accidental contact, thus preventing the test sample from shifting during the testing process. In addition, after pulling the abutment rod to disengage the limiting protrusion from the gear, the unlocking component can be rotated to unlock it. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A scratch resistance testing structure for furniture coating layers includes a testing platform 1, a testing unit 2 and a delivery unit 3 on the top of the testing platform 1, the delivery unit 3 includes a tray 31 and a fixing component 4 on the tray 31, the tray 31 is connected to a drive unit inside the testing platform 1 for transporting test samples;

[0023] The fixing component 4 includes abutment 41 and unlocking component 42. A stop component 5 is provided between abutment 41 and unlocking component 42. The stop component 5 is used to fix the unlocking component 42 so as to drive abutment 41 to press the test sample.

[0024] In some embodiments, the detection unit 2 includes a detection needle. During the detection process, the detection needle is pressed against the detection sample by adding weights of different weights. The detection sample is moved towards the detection unit 2 by a driving device when it is fixed. The detection needle is used to scrape the sample to observe the scratches.

[0025] Furthermore, the fixing component 4 also includes a bracket 43, which is fixedly connected to the top of the tray 31. The abutment 41 is rotatably connected to the side of the bracket 43 via a rotating seat 44. The abutment 41 has an L-shaped structure and the unlocking component 42 is located at its top.

[0026] Furthermore, the bottom of the unlocking component 42 is circular, and its top extends outward to form a push rod. The unlocking component 42 is rotatably connected to the top groove of the abutment component 41 through an eccentric shaft 45, and the unlocking component 42 abuts against the bracket 43 through eccentric rotation.

[0027] In specific operation, the unlocking part 42 is fixedly connected to the eccentric shaft 45. Then the unlocking part 42 and the abutment part 41 rotate eccentrically. After the unlocking part 42 rotates to a certain position, it abuts against the bracket 43. The abutment action can drive the movable end of the abutment part 41 to rotate half a circle toward the test sample, thereby achieving the function of pressing the test sample.

[0028] Specifically, a rubber pad is provided on the bottom surface of the movable end of the abutment 41.

[0029] More specifically, the stop assembly 5 includes a connecting part 51, which is fixedly connected to the side of the abutment 41. A stop rod 52 is slidably connected inside the connecting part 51, and a stepped groove 511 is provided. A limiting part 53 is provided at the top of the stop rod 52, and a spring 54 is sleeved around the limiting part 53 between the limiting part 53 and the stepped groove 511.

[0030] In general, it also includes a gear 55, which is fixedly connected to the end of the eccentric shaft 45. The limiting part 53 is engaged with the tooth groove of the gear 55 by the limiting protrusion 531 at the top. The limiting protrusion 531 has a guide slope on one side that slides against the gear 55.

[0031] Finally, the bottom of the abutment 52 is provided with a push handle, and the side of the rotating seat 44 is provided with a clearance groove 441 to avoid the push handle.

[0032] In this embodiment, as Figure 5 As shown, when gear 55 rotates clockwise, the limiting part 53 slides against the tooth groove through the action of the abutment rod 52, spring 54 and guide inclined surface. Conversely, when gear 55 rotates counterclockwise, the limiting part 53 stops the tooth groove through the limiting protrusion 531, realizing the unidirectional rotation of the unlocking part 42. By fixing the unlocking part 42, the purpose of pressing the test template with the abutment part 41 is achieved.

[0033] Working method: When working, the test sample is placed on the tray 31. When the unlocking part 42 is rotated, the unlocking part 42 and the abutment part 41 rotate eccentrically and abut against the bracket 43. Through the abutment action, the movable end of the abutment part 41 is driven to rotate half a circle to one side of the test sample to achieve the function of pressing the test sample.

[0034] The unlocking part 42 rotates synchronously with the eccentric shaft 45, and the eccentric shaft 45 is fixedly connected to the gear 55. When the gear 55 rotates clockwise, the limiting part 53 slides against the tooth groove through the action of the abutment 52, the spring 54 and the guide inclined surface. Conversely, when the gear 55 rotates counterclockwise, the limiting part 53 stops the tooth groove through the limiting protrusion 531, so as to realize the unidirectional rotation of the unlocking part 42. By fixing the unlocking part 42, the purpose of pressing the test sample against the abutment 41 is achieved.

[0035] The drive unit drives the tray 31 to move toward the detection unit 2, and the scratch resistance of the coating layer is tested by the scratches on the test sample by the detection needle.

[0036] 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.
