Detailed description of the invention
As shown in Figures 1 to 5, this utility model mainly includes pumping chamber 1, pressurized spring 2, pumping chamber's piston 3, supercharging slide block 4, drives slide block 5 and bolt 6, below in conjunction with accompanying drawing, this utility model is described in detail.
As shown in Figure 1, pumping chamber 1 is the circular metal part that upper end is uncovered, internally installed You Liangge pumping chamber piston 3 in pumping chamber 1, between Liang Ge pumping chamber piston, pressurized spring 2 is installed, pressurized spring can be selected for butterfly spring, is provided with supercharging slide block 4 in the bottom of pumping chamber 1, drives slide block 5, bolt 6 and pad 7. Bolt 6 is threadably mounted on the sidewall of pumping chamber, and bolt 6 is also connected with driving slide block 5, for convenience of the installation of bolt, as shown in Figure 2, it is cylindrical for driving slide block, drives skid to be arranged on the inside of pumping chamber, is provided with, on slide block, the screwed hole 51 coordinated with bolt thread driving. Adjust driving slide block 5 position in the pumping chamber by rotating bolt 6, and drive slide block vertical with the glide direction of supercharging slide block; Supercharging slide block 4 is cylindrical structural, and supercharging skid is arranged on the inside of pumping chamber, and the top of supercharging slide block is connected with pumping chamber's piston base of lower section. Pad 7 is set between the nut and pumping chamber of bolt, to ensure the stability between bolt and pumping chamber.
As shown in Figure 4, Figure 5, the first inclined-plane 41 it is provided with in the bottom of supercharging slide block, as shown in Figure 2 and Figure 3, it is provided with the second inclined-plane 52 with the first contact of incline plane at the top driving slide block, supercharging slide block 4 can be extruded when driving slide block 5 to move right and move up thus pumping chamber's piston below jack-up, and then change the pretightning force of pressurized spring. During use, this slide block pressurizer is arranged on the bottom of frcition damper, illustrates for a kind of frcition damper below.
As shown in Figure 6, frcition damper includes upper shell 81, operating bar 82, upper cover 83, swelling inner sleeve 84, swelling overcoat 85 and inner core 86, inner core 86 is for cylinder-like structure and vertically places, the bottom of inner core is connected with pumping chamber 1 by screw thread, the upper end of pumping chamber is uncovered, and the upper end of pumping chamber is connected with the inner thread of inner core. Being provided with some groups of oil throughs on the outer wall of inner core, axially arranged along inner core of some groups of oil throughs, the oil through often organized circumferentially is uniformly arranged, and the effect of oil through is used to transmission oil liquid pressure. The outer wall of inner core is provided with the projection of annular, distance between projection and inner core top is more than the distance between bottom projection and inner core, inner core above projection is cased with rubber bodies 87, rubber bodies 87 is columnar structured, the inwall of rubber bodies and the wall contacts of inner core, being provided with spiral friction plate 88 on the outer wall of rubber bodies, spiral friction plate is spiral helicine metalwork.A sealing mechanism it is respectively arranged at two ends with up and down in rubber bodies 87, sealing mechanism is made up of swelling inner sleeve 84 and swelling overcoat 85, swelling inner sleeve is the hollow structure of truncated cone-shaped, the inwall of swelling inner sleeve is cylindrical, the inwall of swelling inner sleeve and the wall contacts of rubber bodies, be provided with the breach of a bar shaped in swelling on set. Swelling overcoat is loop configuration, and the inwall of swelling overcoat is truncated cone-shaped, the contact internal walls of the outer wall of swelling inner sleeve and swelling overcoat. Being provided with female thread on swelling overcoat 85, the swelling overcoat of top is threadeded with upper cover 83, and the swelling overcoat of lower section is connected with projecting thread.
