The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Fig. 1 is that the structural representation of some lacquer sleeve is automatically twisted in the leakproof of the utility model bolt.As shown in Figure 1, the stubborn point automatically of bolt leakproof lacquer sleeve comprises: sleeve body 1, marking pen 2, elastic compression assembly.Wherein, sleeve body 1 is a hollow structure, and the middle and lower part is provided with shoulder 6; Marking pen 2 places above-mentioned hollow structure, and shoulder 6 is passed in written lower end, and the nib upper end is crimped on shoulder 6; The elastic compression assembly is crimped on the top of marking pen 2, fixedlys connected with sleeve body 1.
The top of sleeve body 1 is provided with square through hole, the middle part is provided with cylindrical hole, the bottom is a collet head, the collet head setting with wait the corresponding through hole of shape that tights a bolt, the central symmetry axes of the square through hole of sleeve body 1, cylindrical hole and collet head through hole overlaps, and each through hole up/down perforation, cylindrical hole bottom and collet head transition position are received and are become one to support shoulder 6 for a short time, are used to support the upper end of marking pen 2 nibs.
The pressured spring 3 that contracts in marking pen 2 upper ends is spacing, and compression spring 3 upper ends are spacing by connecting square toes 5.The lower end that connects square toes 5 is located in the square through hole of sleeve body 1, and fixedlys connected by connecting bolt 4 between the sleeve body 1.
During free state, marking pen 2 is at the precompression of compression spring 3 and support under the effect of shoulder 6, nib apart from the distance of collet head lower limb greater than zero and less than waiting to twist half of bolt thickness.
In the utility model, when tighting a bolt, bolt head withstands nib, thereby " is put lacquer " automatically; Tighten finish after, sleeve breaks away from bolt head, marking pen 2 automatically resets under 3 effects of compression spring, puts the lacquer process automatically and finishes, by checking whether bolt head has " varnish stain " sign can realize that the leakproof of bolt is twisted and check on.Under the prerequisite of guaranteed efficiency, the utility model can be finished a lacquer automatically in the rundown process of bolt, prevents from effectively that bolt from leaking to tighten.The utlity model has simple in structure, easily and effectively, Nover practical, the advantage that cost performance is high, the applications that is suitable for very much tightening at needs a large amount of threaded connectors is promoted.
