Description

Technical Field

[0001] The utility model relates to the technical field of vacuum boosters, specifically an aluminum valve body vacuum booster. Background Art

[0002] A vacuum booster is a component that uses vacuum to increase the force applied by the driver to the pedal. Although the structural forms of boosters are different, the general principle is to use a small signal action to control relevant devices of the vehicle with the help of compressed air, high-pressure oil, etc., so as to achieve the purpose of easy use.

[0003] The aluminum valve body vacuum booster mainly consists of a vacuum servo chamber and a control valve body. The vacuum servo chamber is composed of front and rear shells and a servo chamber diaphragm clamped between them, dividing the servo chamber into front and rear chambers. The control valve body includes key components such as an air valve and a vacuum valve. Through precise design and cooperation, these components realize the function of vacuum assistance. Since the aluminum valve body vacuum booster realizes the assistance function through negative pressure, most of the aluminum valve body vacuum boosters are of an integral design. Although this design method makes the internal space of the aluminum valve body vacuum booster more airtight, once its internal components are damaged, the entire aluminum valve body vacuum booster can only be replaced, resulting in waste of aluminum resources. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, most of the aluminum valve body vacuum boosters are of an integral design. Although this design method makes the internal space of the aluminum valve body vacuum booster more airtight, once its internal components are damaged, the entire aluminum valve body vacuum booster can only be replaced, resulting in waste of aluminum resources. The present utility model provides an aluminum valve body vacuum booster.

[0005] The technical solution adopted by the present utility model to solve its technical problems is: an aluminum valve body vacuum booster, including an aluminum valve body vacuum booster body. The aluminum valve body vacuum booster body includes an upper fixing plate, the left side of the upper fixing plate is movably connected to a lower fixing plate, and a fixing mechanism is arranged on the surface of the upper fixing plate;

[0006] The fixing mechanism includes a first disc and a second disc. The inner wall of the first disc is fixedly connected to the surface of the upper fixing disc, and the inner wall of the second disc is fixedly connected to the surface of the lower fixing disc. The left side of the first disc is in close contact with the right side of the second disc. Six hollow screws are inserted into the inner cavities of both the first disc and the second disc. A hollow rod is fixedly connected to the left side of the hollow screw. A tapered column is fixedly connected to the left side of the hollow rod. Threaded rods are threadedly connected to the inner cavities of the hollow screw, the hollow rod, and the tapered column. A movable disc is fixedly connected to the left side of the surface of the threaded rod. The movable disc is movably connected to the inner cavity of the tapered column. Three clamping columns are rotatably connected to the surface of the movable disc. The surface of the clamping column is movably connected to the inner cavity of the tapered column. One end of the clamping column is in close contact with the left side of the second disc.

[0007] Preferably, three concave blocks are fixedly connected to the surface of the movable disc. The inner cavity of the concave block is movably connected to the surface of the clamping column.

[0008] Preferably, six screw sleeves are threadedly connected to the surface of the hollow screw. The left side of the screw sleeve is in close contact with the right side of the first disc. A number of cylinders are fixedly connected to the surface of the screw sleeve.

[0009] Preferably, a tool groove is formed at the top of the threaded rod. The shape of the tool groove is hexagonal.

[0010] Preferably, six fixing rings are fixedly connected to the surface of the hollow screw. A handrail is fixedly connected to the top of the fixing ring.

[0013] The advantages of the present utility model are as follows:

[0014] In this utility model, a tool is used to rotate the threaded rod, causing the threaded rod to move to the right. The movement of the threaded rod drives the clamping post to spread out from the inside of the conical column until one end of the clamping post comes into contact with the left side of the second disc. At this time, the cylinder is rotated, and the rotation of the cylinder drives the screw sleeve to start moving. As the screw sleeve moves, the left side of the screw sleeve comes into close contact with the right side of the first disc, achieving a fixing effect and solving the problem that most aluminum valve body vacuum boosters are integrally designed. Although this design method makes the internal space of the aluminum valve body vacuum booster more airtight, once an internal component is damaged, the entire aluminum valve body vacuum booster has to be replaced, resulting in a waste of aluminum resources.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The following is a further detailed description of this application in conjunction with the attached Figures 1-8 This application will be further described in detail.

[0027] The embodiment of this application discloses an aluminum valve body vacuum booster. Refer to Figures 1-8 , the aluminum valve body vacuum booster includes an aluminum valve body vacuum booster body 1. The aluminum valve body vacuum booster body 1 includes an upper fixing plate 101. The left side of the upper fixing plate 101 is movably connected with a lower fixing plate 102. The surface of the upper fixing plate 101 is provided with a fixing mechanism 2;

[0028] The fixing mechanism 2 includes a first disc 201 and a second disc 202. The inner wall of the first disc 201 is fixedly connected with the surface of the upper fixing plate 101. The inner wall of the second disc 202 is fixedly connected with the surface of the lower fixing plate 102. The left side of the first disc 201 is in close contact with the right side of the second disc 202. Six hollow screws 203 are inserted into the inner cavities of the first disc 201 and the second disc 202. The left side of the hollow screw 203 is fixedly connected with a hollow rod 210. The left side of the hollow rod 210 is fixedly connected with a tapered column 211. A threaded rod 204 is screwed into the inner cavities of the hollow screw 203, the hollow rod 210 and the tapered column 211. The left side of the surface of the threaded rod 204 is fixedly connected with a movable disc 212. The movable disc 212 is movably connected with the inner cavity of the tapered column 211. Three locking posts 214 are rotatably connected to the surface of the movable disc 212. The surface of the locking post 214 is movably connected with the inner cavity of the tapered column 211. One end of the locking post 214 is in close contact with the left side of the second disc 202.

[0029] Refer to Figure 3 and Figure 4, a concave block 213 is fixedly connected to the surface of the movable disk 212. The number of concave blocks 213 is three. The inner cavity of the concave block 213 is movably connected to the surface of the clamping post 214. Through the arrangement of the concave block 213, the clamping post 214 can rotate. When the movable disk 212 moves to the left, the clamping post 214 moves into the interior of the conical column 211 while rotating in the inner cavity of the concave block 213, avoiding the situation where the clamping post 214 gets stuck;

[0030] Refer to Figure 3 and Figure 4 , a screw sleeve 206 is threadedly connected to the surface of the hollow screw 203. The number of screw sleeves 206 is six. The left side of the screw sleeve 206 is in close contact with the right side of the first disk 201. A cylinder 207 is fixedly connected to the surface of the screw sleeve 206. The number of cylinders 207 is several. Through the arrangement of the screw sleeve 206, the hollow screw 203 is fixed, avoiding the situation where the hollow screw 203 moves left and right inside the first disk 201 and the second disk 202. Also, through the arrangement of the cylinder 207, when the internal parts of the upper fixing disk 101 and the lower fixing disk 102 are damaged, the screw sleeve 206 can be quickly separated from the surface of the first disk 201 through the cylinder 207;

[0031] Refer to Figure 3 and Figure 4 , a tool slot 205 is opened at the top of the threaded rod 204. The shape of the tool slot 205 is hexagonal. Through the arrangement of the tool slot 205, a tool can be inserted here to rotate the threaded rod 204. The rotation of the threaded rod 204 causes it to move to the left. The movement of the threaded rod 204 causes the clamping post 214 to retract into the interior of the conical column 211, thereby facilitating the removal of the hollow screw 203, the hollow rod 210, and the conical column 211 from the interior of the first disk 201 and the second disk 202;

[0032] Refer to Figure 3 and Figure 4 , a fixing ring 208 is fixedly connected to the surface of the hollow screw 203. The number of fixing rings 208 is six. A handrail 209 is fixedly connected to the top of the fixing ring 208. Through the combined use of the fixing ring 208 and the handrail 209, when it is necessary to remove the hollow screw 203, the hollow rod 210, and the conical column 211 from the inner cavity of the first disk 201 and the second disk 202, just pull the handrail 209 to take them out;

[0033] Refer to Figure 7, a first clamping block 3 is fixedly connected to the surface of the first disk 201. The number of the first clamping blocks 3 is three. A second clamping block 4 is fixedly connected to the surface of the second disk 202. The number of the second clamping blocks 4 is three. The surface of the first clamping block 3 is engaged with the surface of the second clamping block 4. By using the cooperation of the first clamping block 3 and the second clamping block 4, the first disk 201 and the second disk 202 can be strengthened, and the positions of the first disk 201 and the second disk 202 can be made more stable;

[0034] Refer to Figure 7 and Figure 8 , a ring plate 5 is fixedly connected to the left side of the upper fixed disk 101. A ring-shaped sealing sleeve 6 is fixedly connected to the surface of the ring plate 5. The material of the ring-shaped sealing sleeve 6 is rubber. The surface of the ring-shaped sealing sleeve 6 is movably connected to the inner cavity of the lower fixed disk 102. Through the setting of the ring-shaped sealing sleeve 6, the tightness of the connection between the upper fixed disk 101 and the lower fixed disk 102 is stronger, and then the air leakage at the connection between the lower fixed disk 102 and the upper fixed disk 101 can be avoided.

[0035] Working principle: The aluminum valve body vacuum booster body 1 is widely used in the hydraulic braking systems of passenger cars and light commercial vehicles. During use, the connection pipelines of the vacuum booster should be regularly checked for air leakage, whether the vacuum source is normal, etc. to ensure its normal operation. At the same time, when in use, first assemble the internal parts of the upper fixed disk 101 and the lower fixed disk 102. After the assembly is completed, insert the ring plate 5 and the ring-shaped sealing sleeve 6 into the inside of the lower fixed disk 102 to make the connection between the upper fixed disk 101 and the lower fixed disk 102 more sealed. Then rotate the upper fixed disk 101. The rotation of the upper fixed disk 101 drives the first disk 201 to rotate. The rotation of the first disk 201 drives the first clamping block 3 to rotate until the first clamping block 3 is engaged with the second clamping block 4. At this time, the holes opened on the surfaces of the first disk 201 and the second disk 202 are just aligned. Then the hollow screw 203, the hollow rod 210 and the conical column 211 can be inserted into the inside of the first disk 201 and the second disk 202. Subsequently, use a tool to rotate the threaded rod 204 to make the threaded rod 204 move to the right. The movement of the threaded rod 204 drives the clamping column 214 to spread out from the inside of the conical column 211 until one end of the clamping column 214 contacts the left side of the second disk 202. At this time, rotate the cylinder 207. The rotation of the cylinder 207 drives the nut sleeve 206 to start moving. As the nut sleeve 206 moves, the left side of the nut sleeve 206 is in close contact with the right side of the first disk 201. At this time, the fixation of the upper fixed disk 101 and the lower fixed disk 102 is completed. When the internal parts are damaged and the upper fixed disk 101 and the lower fixed disk 102 need to be disassembled, just repeat the above operations.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will also have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
