Description

M274207 IV. Creation Instructions α) [I. New Technology Field] This creation belongs to the technical field of brake adjustment tools, especially for the improvement of tools for adjusting the pistons of brake cylinders. [II. Prior technology] According to the prior technology, a sub-pump return pressure device for adjusting the piston in the brake sub-pump is shown in Figure 2 and used in this sub-pressure return device. Come to use the "piston" in-situ tool, especially the brake cylinder that can be used to achieve its maximum function. The brake cylinder must be used to bring the piston back to the page to turn the piston bismuth. And its structural composition is based on ^): the end pivot group lever (92), and the other end uses two "moving sleeves (9 4) protruding from the trap (.9 4 1).", "Ί, when in use It is the plug of the turntable at one end of the back pressure tool and the sleeve (94): 3) abuts on the top edge of the card seat that lives on the outer edge of the sub-pump, when the lever ^ 9 ^ 1) the card Stop the piston and push it into the chestnut '. However, the car branch is because of various obstacles: when it is moving: it has two, and the position of the piston is narrow. Often, the turntable (9 3) with a shape other than 5 cannot be placed smoothly. ， Mainly original ：: Before the press tool: except for sex, the other reason is that the stopper (9 4 = ”type structure, which makes it impossible to use; 糸 仃 糸 糸 adjust the piston operation. There is also a customary creative department announcement No. 39 2552 of the improved structure of the pq adjuster. "

Page 5 M274207 丨 · IV. Creation Instructions (2) — The sample is on the screw body (9 i) a ”with thread segments on the outer edge, and the convex portion (911) set is used on the other end), the outer edge Then the screw sleeve is used to adjust the sleeve (9 4). The difference between this practice and the only difference is that the outer edge of the sleeve (9 4) protrudes: Block ::: 2) The circle diameter is slightly reduced. Entry narrow "9 Because the circle diameter of the stopper (9 4 1) is small, if the outer seat of the sub-pump cannot be used for the stopper (9 4 1), the helmet method: Adjusting the work to form the use of the ;; = profit =: = = to improve the lack of use of the above two conventional uses, the author did not think about the direction of improvement. 1Especially in view of this, the author has created this book with many years of manufacturing experience, aiming at the above-mentioned customary creation ^ 2: R & D and ΠΪ ’s creation of this creation "Sha ===== good", to improve the above-mentioned custom Missing. i-state ,,, and mouth structure modification [Creation content] The main purpose of this creation is to provide a kind of "improvement of eight sensitive cars", which is to make the sub-pump back pressure regulator use the whole structure of the two back-pressure regulators, and further make The tool can easily adjust the piston of the wide sub-pump suitable for the end structure. ”No matter the brand and model brake edge to achieve the above-mentioned effect and purpose, the structure of the device is improved.” Its composition includes an industrial brake cylinder pump return cylinder, and a limit baffle, i 2 Xi body, a position plate, In the thread section of the driving sleeve driving sleeve screw group; one ;: the outer edge peripheral surface is formed for this while the end edge pivot group is driven and defended, the other end is M274207 3. Creative instructions (3) a larger circular baffle system is formed It is used to form a larger diameter blocking arrangement on the driving sleeve to facilitate the function. There is a good implementation of the structure [four, hereby with the map requester structure, drive, it should be provided with the drive shaft (13 have two fixed center edge, use, and sub-pump back to the original example and configuration The special creation is to make its style revisited. "Sleeve (middle: tool driven by the sleeve drive) 'The position of the branch (fixed joint of the plug diameter, used to nest the positioning plate, and the The sleeve hole on the limit position is sleeved on the outer edge of the driving sleeve and abuts against the blocking portion of the end edge. At the same time, the cover edge of the sleeve hole is covered with another sleeve hole. It is sleeved on the driving sleeve, so that the limit stopper can be moved with the tool body to reduce the thickness and the wide distance between the limit seeding plate and the positioning plate. It can be used for adjusting the brake cylinders of different models and brands. = The technology, methods and effects used are detailed in the following diagrams. I believe that the above objectives of this creation 'can be obtained in-depth and specific understanding. Implementation Mode] Can further understand this creation The structural design and technology are described below: Figures 3 to 5 Creation "The brake cylinder back pressure system consists of a tool body (1 0), a positioning disk (2 0) 3 Q) 'and a limit assembly (4 0) and other component groups (1 0) are a long Shape screw, the outer circumferential surface of the screw group forms a thread section (1 1) of the screw group, and the top end rod (1 2) and the bottom end edge are provided with a larger diameter fixed portion fixed portion (1 3) The bottom edge of the circle is convexly arranged at an appropriate angle at 1 3 1 ^ for connecting the positioning plate (20), and a magnetic body (1 4) is placed, and the magnetic body (1 4) is borrowed.

M274207 IV. Creation instructions (4) The positioning plate (20) is attracted to increase the stability of assembly and binding. The positioning disc (20) is a circular disc body, which is used to embed the brake sub-cylinder. The disc surface corresponding to the tool (胄) is suitable for two persons: a set of two positioning posts (131) is provided. The positioning holes of the group (the other side of the disk at 2 f are convexly provided with a plurality of driving heads that bite into the brakes, 2). It is further explained that the number and arrangement of the driving branches are determined by the brand and form of the brake cylinder, and the driving sleeve (30) can be screwed into the tool S '^ 2) The long cylindrical part at the threaded section (1 1) has a driving part (3 1) at the top end, which can be used by a user to drive the driving sleeve (30) with an open spanner, and a large round diameter is formed at the bottom end. The blocking portion (32) is limited for the position of the back pressure tool when the piston is pushed. The limiting baffle (40) is a long rectangular plate body, and a set of holes (41) is provided at the center of the plate, so that it can be adjusted to pass through the driving rod (12) and set on the The outer side of the driving sleeve (30), and the back edge surface of the set of holes (41) are adjacent to form a cover hole (4 2) with a larger diameter. The cover hole (4 2) is just Cover the supporting portion (3 2) of the driving sleeve (30), so that the back plate surface of the limiting baffle (40) and the outer edge surface of the positioning portion (3 2) are several Close-fitting combined configuration. According to this, 'using the above-mentioned components, when the sub-pump pressure return device is used, the limit baffle (40) can be used in a movable manner with the tool body (100), so that the sub-pressure return device can be conveniently used. Various narrow spaces are used for adjustment, and at the same time, the thickness and wide distance between the limiting baffle (40) and the positioning plate (20) are further reduced (as shown in Figure 5), thereby facilitating the back pressure of the sub-pump.

It is against the back edge surface of the drive sleeve and A large-diameter driving sleeve is formed on the retaining part, and the tool body is used in combination with a wide distance, which is beneficial to the function of adjusting the pump back to the pump. The moving tool has a larger circle as a structure-improved body. One end pivot is used to nest an outer edge, and the cover hole on the end edge of the sleeve tube is used to reduce the limit. The limiter is used for, The package of the driven positioning plate is characterized by the cover and the baffle on the hole through the sleeve. It can be screwed, dried, and formed at the other end, and a driving sleeve is formed on the driving sleeve. Outer ', and the hole of its set hole must cover the thickness type, brand brake between the movable mode and the positioning plate. Page 11
