[0001] The utility model relates to the technical field of paint film thickness detection, in particular to a door panel paint film thickness detection device. BACKGROUND

[0002] The needle puncture method is a clear requirement in the detection standard of wooden door paint, and when measuring, the thickness measuring needle needs to be stretched out of the needle hiding cylinder and vertically punctured into the door panel paint to the base material. After the measurement is completed, the puncture point needs to be marked first (marking first can prevent forgetting the sampling point position in the later period), then the scale representing the puncture depth is read and recorded, and finally the thickness measuring needle is pushed back to the needle hiding cylinder.

[0003] Before the data is recorded, the measuring end (sharp end) of the thickness measuring needle is always outside the needle hiding cylinder. During this process, the measuring end of the thickness measuring needle touches external objects, which can easily cause the user to be injured (the user touches the measuring end) and the measuring end to be deformed (the measuring end touches external hard objects). Therefore, we propose a door panel paint film thickness detection device that can protect the measuring end of the thickness measuring needle after puncturing. UTILITY MODEL CONTENTS

The rotating shaft of the fifth gear 46 penetrates the transmission mounting plate 22 and is connected with a rocker 47. When the rocker 47 is rotated, the rocker 47 drives the fifth gear 46 to rotate, and the fifth gear 46 drives the thickness measuring needle 31 to slide through rotation. At the same time, when the fifth gear 46 rotates, the first gear 42 is also driven to rotate through the fourth gear 45, the third gear 44 and the second gear 43.

[0036] The scale table 41 is provided with a scale ruler, and the pointer of the scale table 41 points to the value on the scale ruler, which represents the penetration depth of the thickness measuring needle 31. The scale table 41 is installed on the front side of the transmission mounting plate 22, and the rotating shaft of the first gear 42 penetrates the transmission mounting plate 22 and is connected with the pointer of the scale table 41. When the first gear 42 rotates, the pointer also rotates and points to different values through rotation.

[0037] The one-way device is used to limit the rotation direction of the third gear 44, so that the third gear 44 can only rotate in one direction, and further limits the first gear 42, the second gear 43, the fourth gear 45 and the fifth gear 46 connected with the third gear 44 to rotate in one direction. The one-way device can be matched with a one-way bearing or a ratchet wheel 56 and a pawl 55. When the one-way bearing is used, the rotating shaft of the third gear 44 is connected with the transmission mounting plate 22 through the one-way bearing (not shown in the figure). When the ratchet wheel 56 and the pawl 55 are used, the inner wall of the transmission mounting plate 22 is provided with the pawl 55, the rotating shaft of the third gear 44 is externally provided with the ratchet wheel 56, and the pawl 55 abuts against the ratchet wheel 56.

[0039] The outside of the thickness measuring needle 31 is sleeved with a thrust spring 32, the upper end of the thrust spring 32 is connected with the outer wall of the thickness measuring needle 31, and the lower end of the thrust spring 32 is connected with the inner wall of the needle hiding groove; after the fourth gear 45 is separated from the fifth gear 46, the thrust spring 32 will push the thickness measuring needle 31 to reset upward. The handle 23 is detachably connected to the upper side of the needle hiding cylinder 21, and after the thickness measuring needle 31 resets upward, the top end of the thickness measuring needle 31 is attached to the lower end of the handle 23.

[0040] The inner side of the installation groove is slidably connected with a gear strip 48, and a sliding groove is opened in the inner side of the installation groove. The gear strip 48 is placed inside the sliding groove, and the sliding direction of the gear strip 48 is limited by the sliding groove. One end of the gear strip 48 and the inner wall of the installation groove are connected with a reset spring 49, and the gear strip 48 will slide under external force.
