Abstract
The utility model discloses a pullout dismantling device for dismantling parts with internal threads or external threads, such as valve cores, end covers, plugs and linings. One end of a pullout screw rod of the pullout dismantling device is provided with a thread end in threaded connection with a part to be pulled out of a product during use process, the other end of the pullout screw rod is provided with a fixed end, and a hole vertical to the central axis of the pullout screw rod is machined in the fixed end; a rod penetrates through the hole; a baffle is in threaded connection with the pullout screw rod; a hollow cylindrical support ring is supported between the product and the baffle, and the hollow circle diameter of the hollow cylindrical support ring is more than the size of the part to be pulled out. The pullout dismantling device realizes uniform force application, ensures the pulling force in a direct line, avoids the product from being bent or damaged and makes the whole dismantling process become time and labor saving.
Description
Technical field
The utility model relates to a kind of extracting tool, is meant that specifically a kind of dismounting has the take-off device of parts such as internal thread or externally threaded spool, end cap, plug, lining.
Background technology
In the prior art, dismounting such as destroy seven, destroy booster on eight, the spool of steering wheel, plug, lining etc. all are to be screwed into product internal thread (external screw thread) with the corresponding bolt (nut) that takes out, bolt (nut) is clipped on the Hu Tai, goes out the part of product with the manpower hard draw.Because firmly inhomogeneous in the process of choosing, direction of exerting oneself and product removing direction are easy to cause crooked or other damage of product not point-blank.One people adopts this method to be not easy to finish to choose this work of part, and consumption power is consuming time again.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of firmly evenly, firmly point-blank, be unlikely to pull out and draw product to make product crooked or pull, thereby make the extracting tool that it is time saving and energy saving that whole unloading process becomes.
At above-mentioned technical problem, the utility model provides a kind of take-off device, an end that takes out screw rod be provided with when using with product in the end of thread that is threaded mutually of the parts that will choose, be provided with stiff end at the taking-up screw rod other end, have and take out the perpendicular hole of screw stem line in the stiff end; Be installed with bar in the hole; Baffle plate is connected with the taking-up screw flight; The hollow cylinder support ring is supported between product and the baffle plate, and the open circles diameter dimension of hollow cylinder support ring is greater than the size of the parts that will choose.
The end of thread is internal thread or the external screw thread that is complementary with the parts that will choose.Taking out screw rod is that left-hand thread is connected with baffle plate.Taking out screw rod is that the whole body of rod is threaded.Take out between screw rod and the end of thread and be connected with smooth round bar, smooth round bar length is that 1/3 of hollow cylinder support ring is grown.Baffle plate is longer than bar, its length 〉=15cm.
After adopting take-off device, method for dismounting is time saving and energy saving, guaranteed withdrawal force evenly, when having prevented dismounting product injured, damage, thereby guaranteed the repair quality of product to a certain extent.
Description of drawings
Accompanying drawing is the take-off device schematic representation of apparatus.
The specific embodiment
In the accompanying drawing, described take-off device mainly is made up of four parts, comprises bar 1, baffle plate 2, hollow cylinder support ring 3, takes out screw rod 4.During use, be screwed on the parts that will choose 10 in the product 5 taking out screw rod 4 ends of thread 6.The parts 10 that will choose in the product 5 have internal thread or external screw thread, and the end of thread 6 keeps being complementary with it.Hollow cylinder support ring 3 is enclosed within on the product 5, and the open circles diameter dimension of hollow cylinder support ring 3 is greater than parts 10 sizes in the product 5 that will choose, thereby can guarantee that the parts 10 that will choose are suggested.Baffle plate 2 is supported on the hollow cylinder support ring 3, and takes out screw rod 4 for being threaded, and is preferably the left-hand thread connection.Take out screw rod 4 and be provided with stiff end 9, have and take out the perpendicular hole 7 of screw rod 4 central axis in the stiff end 9, bar 1 passes from hole 7.Because it is that plus thread connects that the end of thread 6 is screwed into the screw thread of the parts 10 that will choose, take out screw rod 4 and baffle plate 2 for left-hand thread is connected, fix bar 1 during dismounting, be rotated counterclockwise baffle plate 2, taking-up screw rod 4 is just taken advantage of a situation and is raised, and finally takes up the parts 10 that will choose in the product 5.If take out screw rod 4 and baffle plate 2 for plus thread is connected, fix bar 1 during dismounting, the baffle plate 2 that turns clockwise still can reach the effect of the parts of choosing equally.
Taking-up screw rod 4 can be processed as the whole body of rod and be threaded, and also can between the taking-up screw rod 4 and the end of thread 6 smooth round bar 8 be set, and smooth round bar 8 length are 1/3 length of hollow cylinder support ring 3, thereby can save the thread making operation of taking out screw rod 4.The height of hollow cylinder support ring is generally 6cm.For more laborsaving, baffle plate 2 is long more laborsaving than bar 1 generally speaking, and its length 〉=15cm holds baffle plate with both hands and is advisable.
After adopting take-off device, only need butterfly 2 gently, just can take advantage of a situation and mention the part that to choose.Compared with prior art, the utility model utilization is dismantled plug, spool, end cap etc. with the principle that pulling capacity is converted into turning moment, thereby overcome previous method consumption power, firmly uneven, power thrusts and product removing direction be point-blank shortcoming not, strong avoided the injured of product in the dismounting and damages.This product is specially adapted to destroy seven, destroys the booster on eight, the spool of steering wheel, lining etc.
