Description of invention: [Technology 彳 城 city of invention] Field of invention [0001] The present invention relates to a stalking door that is erected to furniture, such as a flow station, and a bridge It can significantly reduce the noise generated when the door is closed. L Dongshu 3 Background of the Known Skills [0002] Generally, the door is erected to cover or protect the items placed in the home, and it is made of wood or metal. [0003] Wooden doors are generally erected to the home by spring hinges, such as tables, wardrobes, flow tables, and the like. The doors have different shapes depending on the overall shape of the furniture, but each door is identical in the principle of opening/closing the door by a hinge. [0004] I generically erected to a front door or hallway and is configured to withstand an external force applied from the outside. The metal door is placed in a different position than the wooden door, but the structure of the door around the hinge switch is the same. [〇〇〇5] The opening of η represents the door corner of the frame or wall that is connected to the home. It is separated from the frame or wall. As far as the metal door is concerned, since the sound is very loud when the door is closed, in order to reduce the noise, a hydraulic cylinder = room is usually installed separately. In the case of a wooden raft, since η is very light and the squeak produced when tn is closed is smaller than the metal door, an additional noise damper is not required. An example of a noise damper is disclosed in Korean Patent No. 354,593, which is named as a door shock absorber. The shock absorber is composed of a cylinder filled with oil and a plug, wherein the flow rate of the oil is adjusted by a check valve. The shock 5 1290602 includes, as shown in FIG. 1, a cylinder 200 having an open cylindrical front portion a protrusion 201 formed on an inner wall of the cylinder barrel, and a rear portion formed at the rear a rod 21 具有 having a fixed length on the bottom; a piston guided along an inner peripheral surface of the red cylinder 200 and having an open cylinder 5 opening > rear 'a bushing 165 formed on a rear peripheral edge of the rear portion for contacting the protruding portion 2〇1 of the cylinder tube to prevent the piston from moving outside the cylinder tube 2; a fixing member 160 which is erected to a port behind the piston and prepared A rod 21 is passed through one of the holes, a stuffing 166, which is erected to a front side of the fixing member 160, and is provided with a hole 21 through which a rod 21 is passed, and a supporting member 153, 10 is disposed to one end of the rod 210. Upper portion, a spring fixing member 140 is erected to the supporting member 153, and is provided with first and second check valves 150, 152 inserted into a rear of the spring fixing member 140, and a spring extending to the spring fixing member HO Closing one of the front inner wall return springs 130; and inserting the front of the piston 1〇〇 There is also a buffer 110 that closes the ball 112. [0007] In particular, the rod 210 spanned in the cylinder 200 is coupled to the spring retaining member 14''' through the intermediate portion of the retaining member 160, and through an intermediate portion of the support member 153 spaced from the packing 166, and The intermediate portion of the first and second check valves 150, 152 is fixed to the wadding 166 inside the piston 1''. The spring retaining element 140 repeatedly compresses and releases the return spring. 20 [〇〇〇8] When an external force is applied to the damper 11A, since the shock absorber is provided, the spring fixing member 140 presses the return spring 130, and the rod 210 is supported in the cylinder 200. Due to the spring fixing member 140, the outer diameters of the first and second check valves 150, 152 and the supporting member 153 are smaller than the inner diameter of the piston 1 ,, and oil can flow therebetween. The degree of force of the first and second check valves 1290602 (10) spaced apart from the magazine fixing member 140, and the thickness of the hole in the (4) cutting element, by the compressible resistance (filled in the piston (10)) That is, it is incompressible (four)), and it is called clear in the direction of the (four) 岐 element 14.言句 5 [〇_ Oil flows along the outer surface of the spring-loaded component to support the external shock force. [0011] After the vibration shock n11 () is reduced, (4) the first and second check valves 150 and 152 of the hole for supporting the component return to their original shapes, and are moved to the original position by the return spring 130, so that The oil flows between the peripheral surface of the piston 1〇〇 and the support member 153. [0012] However, the shock absorber has the disadvantage that the door of the furniture or the countertop cannot be in intimate contact with its opposite frame, but is spaced from the frame by a fixed spacing. [0013] In particular, considering the degree of vibration generated when the door is closed, the first and second check valves 150 and 152 of the erection 15 in the piston have an outer diameter slightly different from the inner diameter of the piston 1 。. In this case, the first and second check valves 150, 152 block the holes of the support member 153 such that the oil flows only between the inner peripheral surface of the piston 1〇〇 and the support member 153. [0014] In order to quickly return the oil and provide sufficient cushioning action, the spring 20 must have considerable flexibility. Therefore, it can be used in a relatively large and cumbersome door. If the shock absorber is erected to a small or light door, when the door is closed, a fixed distance between the door and the frame of the furniture or the counter will be restored by the spring force of the return spring 130. [0015] If the return magazine 130 is manufactured to have a small modulus of elasticity to guide the 7 1290602 door into close contact with the frame of the furniture or the flow table, the first and second check valves 150 and 152 must be fabricated to have An outer diameter that is significantly different from the inner diameter of the piston 100 to quickly return the piston 100. Therefore, it has the disadvantage of being unable to absorb the strong shock force applied from the outside. 5 SUMMARY OF THE INVENTION [0016] Accordingly, the present invention is directed to a shock absorber for a sliding door that substantially obviates the disadvantages and limitations of the prior art. [0017] It is an object of the present invention to provide a shock absorber for a sliding door that is erected to a home, such as a fluidizing cabinet, a wardrobe, etc., which can significantly reduce the noise generated when the door is closed. Another object of the present invention is to provide a shock absorber for a sliding door that absorbs the strong shock force applied to the door and that can be erected to the door regardless of the detail or weight of the door.

Inserted into the outer casing 35. The elastic spring has a good elastic restoring force' and the diameter of the first elastic spring is smaller than the inner diameter of the outer casing π, so that when the first elastic elastic is compressed or loosened, the U 11 1290602 elastic magazine 40 and the outer casing 35 No friction between them. [0041] The elastic spring has a % outer casing and an oil motorized load-bearing body 45 made of soft rubber, and the casing closely contacts the first elastic spring 4''. The oil motorized shield 45 has a diameter that does not contact an inner surface of the outer casing 35. The oil flow blocking housing 45 is provided with a through-hole on the middle portion thereof. The end of the second elastic spring 40 is inserted into the oil flow blocking housing for a desired length and is generally in the shape of a high cap. [0042] Generally, the pressing bracket 50 is inserted into the oil flow blocking housing 45, and the pressing bracket 50 is housed in the housing 35, and the pressing bracket 5 is constituted by a sleeve 1052 and a cover 53. The sleeve 52 has an outer surface that is serrated. The sleeve 52 has a sturdy shape and has a plurality of vertices similar to a star and is inserted into the through hole 46 of the oil flow resisting housing. [0043] The cover 53 extends integrally from the sleeve 52. The cover 53 partially covers the outer surface of the sleeve 52 and is provided with a plurality of oil ports 15a on the outer peripheral surface. Further, the cover 53 is provided with an engaging recess 53b. [0044] The sleeve 52 inserted into the oil flow blocking housing 45 passes through the second elastic spring 55. The second elastic spring 55 has a shorter length than the first elastic spring 40 and has a lower elastic restoring force than the first elastic spring 40. Both ends of the sleeve 52 are supported by the oil flow blocking housing 45 and the inner peripheral surface of the cover 53. [0045] In turn, the wadding 60 and the sealed casing 65 are successively housed in the outer casing 35. The wadding 60 is made of a material such as sponge, and is closely contacted or loosened with the pressing bracket 50 in accordance with the movement of the oil flow blocking housing 45 and the pressing bracket 50. The seal housing 65 is erected to closely contact the wadding 60 to prevent the 12 1290602 from filling the oil leak in the outer casing 35. The 〇-ring is disposed on the outer peripheral surface of the seal housing 65 to maintain a strong sealing force. [0047] Between the seal housing _ intermediate portion and the tampon 60 in the outer casing % is connected to the engagement groove of the compression bracket. The pole has a shape of 5 inspected and is made of a metal material with good corrosion resistance. [〇〇48] The end of the rod 7 is fixed to the pressing bracket_the engaging groove, and the other end is fixed to the rod fixing sleeve 12 of the cylinder. [〇〇49] f The door D of the house or the flow house provided with the shock absorber according to the present invention closes the buffer 37 of the b'HD county piston, and the door (10) vibration force is transmitted to the piston through the buffer 37. At the initial buffering operation, the shock absorber 37 transmitted by the vibration force moves toward the rod 70 and the outer casing 35. In this case, the oil flow supported by the end of the first elastic elastic (10) blocks the casing 45, and the second elastic spring 55 and the pressing bracket 50 are compressed, so that the oil flows in the cylinder 10. [0051] In particular, when the outer casing 35 moves in the cylinder tube 1 to compress the first elastic magazine 40, the inner elastic surface of the outer casing 35 and the oil flow blocking housing 45 first elastic spring 55 and the pressing bracket The outer peripheral surface of the frame 50 flows between, and on the same day, the oil flows along a sleeve 52 of a pressing bracket 5 in the oil flow blocking housing 45, and flows through the second elastic spring 55 to form the pressing 2 The oil flow port 53 & on the 盍 53 of the 〇 木 wood to provide a slight cushioning function by the resistance of the oil. In the second cushioning action, the oil flow blocking housing 45 directly presses the first elastic spring 40. The second elastic spring 55 inserted between the oil flow blocking housing 45 and the pressing bracket 50 is compressed by the action of the pressing bracket 50, so that the oil 13 1290602 flows the blocking housing 45 to closely contact the second elastic magazine 55 and The bracket 50 is pressed. Therefore, only the oil flows between the oil flow blocking casing 45 and the pressing bracket 50, thereby increasing the cushioning function. [0053] In this case, since the diameter of the oil flow blocking housing 45 is immediately amplified by the compression repulsive force of the oil, the oil flow blocking housing 45 closely contacts the inner peripheral surface of the outer casing 35 or is spaced apart from the inner peripheral surface. The desired distance is such that the amount of oil flowing through the oil flow blocking the housing 45 and the inner peripheral surface is small to further increase the cushioning function. [0054] After the external shock force is removed, the second elastic spring 55 is operated such that the 10 oil flow blocking housing 45 has a fixed distance from the pressing bracket 50. [0055] Then, when the door is opened again, the first elastic elastic cyanine 40 pushes the oil flow blocking housing 45 with elastic recovery force to withdraw the outer casing 35 from the cylinder tube 1 . At that time, the oil flows between the oil flow blocking housing 45 and the sleeve 52 by pressing the oil flow port 53a of the bracket, while the pressing bracket 5 and the oil flow blocking 15 housing 45 pass through the second elastic spring 55, And spaced apart from each other. At the same time, the oil passes through the inner peripheral surface of the outer casing 35, and the pressing bracket 5 and the oil flow block the outer peripheral surface of the casing 45. The flow of oil ensures double oil flow for rapid oil return. In the shock absorber according to the present invention, the cylinder 1 accommodates the rod 70 when a fixing bracket 7 is erected to a portion of the furniture or the flow table that the door D hits when closed. [0057] According to the shock absorber of the present invention, as described above, the noise generated when the door is closed can be reduced as much as possible, and a quiet indoor environment can be prepared regardless of the weight or the fine structure of the door. The above disclosure is for illustrative purposes only and is not intended to limit the invention. The teachings of the present invention are applicable to other types of devices. The disclosure of the present invention is for illustrative purposes only and is not intended to limit the scope of the claims. Many improvements, changes are obvious to those skilled in the art.
