Description

Technical Field

[0001] The utility model relates to automobile decorative parts, in particular to a plastic buckle disassembly tool for automobile decorative parts, which can simplify the buckle disassembly method, improve the buckle disassembly efficiency, avoid buckle damage and parts damage, and reduce the cost of replacement parts. Background Art

[0002] As the popularity of cars increases, consumers have higher requirements for the quality of ride, such as more beautiful interior and exterior styling, quieter ride experience, etc. The beauty of the styling inevitably leads to the complexity of the interior and exterior structures, and the complexity of the structure inevitably leads to an increase in assembly buckles to obtain better assembly stability, thereby avoiding problems such as styling ugliness caused by improper assembly or vibration and abnormal noise caused by loose assembly. For example, the "A kind of automobile interior installation buckle" disclosed in CN202833469U (see Figure 1 ), which includes a buckle body 10, the bottom of the buckle 10 is provided with an upper sleeve 20 and a lower sleeve 30 connected together on the upper and lower sides, the upper sleeve 20 is circular, and the lower sleeve 30 is square, the upper sleeve 20 has a column 40 on it, and the two sides of the column 40 are provided with spring pieces 50 distributed in a cone, and the buckle body 10 is made of elastic plastic injection molding. The disassembly of plastic buckles has always been a difficult problem in the assembly of interior and exterior parts: the buckle damage rate is high during the disassembly process, which increases the cost of vehicle model development; the difficulty in disassembly can easily cause damage to parts, which increases the cost of vehicle model development and is not conducive to the analysis of the problem. Therefore, how to ensure the rapid and non-destructive disassembly of plastic buckles has become an important issue.

[0003] CN 216030542U discloses a "vehicle exterior buckle removal tool", comprising a sleeve, a rotating rod embedded in the sleeve and a tightening clamp arranged at one end of the rotating rod; the tightening clamp comprises a tightening ring sleeved at one end of the rotating rod; one side of the tightening ring is provided with two clamping arms; a limiting rod is provided on the sleeve; the middle part of the rotating rod is provided with a first external thread; the inner side of the sleeve is provided with a first internal thread; by rotating the rotating rod, the tightening ring approaches the sleeve along the rotating rod, and tightens and clamps the buckle under the action of the limiting rod, thereby ensuring a better clamping effect; after the tightening ring clamps the buckle, the rotating rod continues to rotate, and when the end of the limiting rod is against the vehicle body, the rotating rod continues to rotate to pull out the buckle, thereby reducing the deformation of the local position of the vehicle body sheet metal part to a certain extent, avoiding the subsequent vehicle body appearance quality not meeting the requirements, and making the pulling out process more labor-saving.

[0004] CN 214818237U discloses "an auxiliary tool for disassembling a top trim strip", comprising a quick-change sleeve, a connecting rod and a handle, wherein the quick-change sleeve is connected to one end of the connecting rod, the handle is connected to the other end of the connecting rod, and the quick-change sleeve contacts the plastic buckle. The auxiliary tool is pressed against the plastic buckle on the mounting hole of the top trim strip of the vehicle body from the inside of the vehicle body, and the part of the plastic buckle extending into the vehicle body is immersed in the hollow of the quick-change sleeve. The auxiliary tool is perpendicular to the mounting surface of the mounting buckle and knocks the handle at the bottom until the plastic buckle is separated from the mounting surface of the vehicle body roof. The auxiliary tool is made of a metal material combined with a plastic handle and has a small size. The purpose of disassembling the top trim strip from the vehicle body roof is achieved by pushing the plastic buckle back from the inside of the vehicle body, thereby solving the current situation that there are no tools available for the installation and disassembly of the top trim strip, avoiding the violent installation and disassembly of the top trim strip, allowing the top trim strip to be used multiple times, increasing the diversity of process verification, and reducing the cost of the research and development process.

[0005] Undoubtedly, the technical solutions disclosed in the above two patent documents are beneficial attempts in the technical field. Utility Model Content
