New description: [New technical field] This creation is related to the detection of oil leakage prevention devices, especially the anti-leakage device installed on the needle bar of sewing machine. [Prior Art] Pressing the equipment such as '--sewing machine, sewing machine and copying car must be equipped with the upper arm, • the machine head and the lower part (10) and the needle plate seat, on the upper arm _ by the main _ step Driven by the sharp mechanism and the curved reduction set to "the presser foot device, the needle bar mechanism and the cutter contact mechanism that drive the head part", and the needle plate money has a feeding mechanism and a lower phase with a hook line device, by means of a needle bar Most of the needles of the mechanism carry the reciprocating puncture fabric on the suture line ^ and match. The hook of the hook line device swings back and forth to the left and right lines to perform the seam rushing operation. The head of the machine will be equipped with the oil supply device and its oil pump. In order to form a circulating automatic oil lubrication system, the relevant mechanism devices can operate smoothly. Huai sew, reduce the machine to persuade the rod machine _ the needle of the towel should be swiveled up and down quickly, so it is easy to break the needle to turn the infiltration (four) flow, resulting in the oil material special machine broken parts, even It is necessary that the weather will be defaced to the sewing fabric, causing material loss, and (4) manpower cleaning operations, so it is necessary to improve it. [New content] M393526 The main purpose and function of this creation is to prevent the oil leakage device from using the sealing sleeve combination _ barrel, can Erqiqi, paste (four) with the needle rod body of the machine to seep the dirt body and sewing fabric, And the sealing is convenient for making, assembling and replacing, and improving the use efficiency. In order to achieve the goal, the creation_machine shaft preventing oil leakage device comprises a fixed shaft cylinder and a miscellaneous-tear-tight scale cylinder; the fixed-center shaft hole is used to guide the shaft rod; the sealing sleeve has The one end socket and the opening thereof are positioned to be fixedly reduced by the sleeve, and the sealing sleeve is provided at the end of the sealing sleeve, and the oil sealing sleeve is radially inwardly extended to be sleeved on the outer periphery of the gift; Inside the oil seal part _ radially inwardly extending - the oil seal ring strip, so that the oil seal ring strip forms a convex arc end end radially inwardly to abut the surface of the turn edge. Preferably, the seal portion of the seal sleeve is provided with two oil seals on top of each other. Moreover, the sealing sleeve has a stop end to support the opposite end of the fixed barrel. In a preferred embodiment, the fixed barrel is adapted to engage the sleeve of the sealing sleeve. The positioning head of the end is set to an enlarged diameter. The positioning head and the sealing sleeve of the arranging cylinder are provided with each other - or opposite pin holes, and the pin and the pin thereof are engaged with the opposite pin holes. [Embodiment] #About the purpose of picking up the narrative, the rib means and its function, the paper gives a feasible example, and the description is as follows: First, please refer to the first picture and the second picture, this creation The machine 1 is also connected to the head 12 of the body 11 to support the needle rod body shaft 丄3 and the cutter transmission group 14 and the like. The step is to provide a group of oil and gas prevention at the upper and lower ends of the machine head i 2 to prevent oil leakage. The device cooperates with the guiding shaft 13 to reciprocate up and down. In the preferred embodiment shown in the first to seventh figures, the shaft rod 3 of the sewing machine 1 of the present invention uses two sets of oil leakage prevention devices, and each group of oil leakage prevention devices includes a metal material fixing shaft barrel 2 and elastic Wear-resistant material sealing sleeve 3. As shown in the figure, the two fixed shaft cylinders 2 are respectively inserted and fixed in the upper and lower fixed holes 5 of the head shank 2, and each of the fixed shaft cylinders 2 has a central shaft hole 2 2 ' to guide the shaft i 3 to penetrate vertically. . The two sealing sleeves 3 each have an end sleeve hole 3丨 and an opening 33 thereof for positioning against the outer circumference of the fixed shaft barrel 2, and the sealing sleeve 3 is further provided with an oil seal portion extending radially inward. 3 2 and its central hole 3 4, and spaced apart from each other - the center of the fixed barrel 2 = the hole U ' is elastically sleeved on the outer circumference of the shaft i 3 . And the second, fifth, fifth and seventh figures, in the actual operation of the shaft 13 of the sewing machine 1, the sealing sleeve 3 extends radially inward along the inner circumference of the oil seal portion 32, and further It can be set as two oils that are separated from each other as shown in the figure. ^ 6 'The oil _ strips 3 6 are radially _ to the convex end, and connected to the outer circumference of the shaft 1 3 continuation & L ping The needle machine ^ needle swollen body ^ is enough to seal to prevent oil leakage, to prevent the needle material body from seeping out the body 11 and sewing fabric, and ... the cover is the same as 3 convenient to make and assemble. Made in the _ barrel 2 position. :;:== 'Develop the relative fixing holes in the head 12 with the # and the positioning 21 is more convenient to engage the sealing head to enlarge the diameter of the positioning head 2i, 15 outside (see the second figure), the sleeve hole of the sleeve 3 31 positioning. "and the other nine rides - the implementation of the money, the creation of the oil leakage prevention device in the head cylinder 2 and the sealing sleeve 3 can be provided with at least - opposite pin holes 2 3, 3, 7 A pin 4 is positioned to engage the two opposite pin holes 2 3, 37. The vertical position can be stepped as shown in the figure, and the positioning head #21 of the fixed barrel 2 and the sleeve 3 of the sealing sleeve 3 are fixed to each other. Each of the opposite pin holes 2 3, 3 7 is provided, and the pin 4 is bent with two pin pins 41 for engaging the two sides of the opposite pin holes 2 3, 3 74 to prevent the (4) sleeve 3 from loosening, and The pin holes 2 3 3 7 on both sides and the mandrel holes 2 2 of the fixed shaft barrel 2 are offset from each other. 本 The original technology is to solve the shortcomings and defects of the prior art, and the key technology is to prevent leakage The sealing sleeve is combined with the m-axis cylinder, which can ensure the tightness and oil leakage to prevent the lubricating oil from oozing out along the needle bar of the sewing machine to smear the body and the sewing fabric.
