Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, and more specifically, it relates to an automotive brake rigid pipe mounting and clamping device. Background Technology

[0002] In off-road vehicle design, the brake is a crucial component in the braking system, transmitting braking force. Its function is to transmit hydraulic pressure from the vacuum booster, brake master cylinder assembly, and electronic actuator assembly to the wheel-side calipers, thus generating braking force. During the assembly or maintenance of the automotive braking system, the brake hoses (metal or composite material hoses) need to be secured to the vehicle body or chassis using metal or plastic clips (brackets). These clips are typically designed as clamps or slots, tightened with bolts (or nuts). Currently, rotating the brake hoses has the following drawbacks: rotation may cause localized torsional deformation of the hose near the clips, affecting hose strength and increasing stress concentration and fatigue fracture risk; to prevent rotation, workers need to manually or forcefully hold the hose in place with tools (such as pipe wrenches or open-end wrenches), which is inconvenient, slows assembly, and easily damages the hose surface due to improper force (e.g., scratching the coating or denting). To address these technical problems, this application proposes a solution. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1 to 7As shown, a clamping device for mounting automotive brake hard tubes includes a fixing frame 1. A fixing plate 104 is fixedly connected to one side of the fixing frame 1. Multiple ball grooves 105 are evenly distributed on the fixing plate 104. Two fluid tube grooves 106 are formed between every two ball grooves 105. Steel balls 12 are rolled within the ball grooves 105. A secondary plate 13 is fixedly connected to one side of the fixing plate 104. The secondary plate 13 also has multiple ball grooves 1301, with two fluid tube grooves 1302 formed between every two ball grooves 1301. The steel balls 12 facilitate the movement of the brake hard tubes within the device as they roll internally, and their protruding surfaces separate each brake hard tube.

[0017] A sliding groove 102 is provided on the same side of the fixing plate 104 and the fixing bracket 1. A through hole 103 is provided in the sliding groove 102. A lead screw 5 is rotatably connected in the through hole 103. A bolt 4 is fixedly connected to one end of the lead screw 5 and a gear 6 is fixedly connected to the other end of the lead screw 5. A shaft 8 is provided on one side of the lead screw 5 and is rotatably connected to the fixing bracket 1. A gear 7 is fixedly connected to one end of the shaft 8. Gear 6 and gear 7 are meshed and connected for transmission. A bevel gear 9 is fixedly connected in the middle of the shaft 8. A protective plate 108 is fixedly connected to the other side of the fixing bracket 1. A bolt 11 is rotatably connected to the protective plate 108. A bevel gear 10 is fixedly connected to one end of the bolt 11. Bevel gear 10 and bevel gear 9 are meshed and connected for transmission. A movable clamping bracket 2 is slidably connected in the sliding groove 102. The main function of the two bolts 4 and 11 in this utility model is to clamp the brake tube at different angles, so that if the wrench of one of the bolts 4 or 11 does not have enough operating space, the other can be used to clamp it.

[0018] like Figure 4 As shown, the movable clamping frame 2 includes a slider 201 slidably connected to the slide groove 102. The slider 201 is screwed to the lead screw 5. The movable clamping frame 2 moves by rotating the lead screw 5, and the slide groove 102 slides on the movable clamping frame 2. A sliding plate 203 is fixedly connected to one side of the slider 201. Multiple ball grooves 204 are provided on the sliding plate 203. A liquid pipe groove 205 is provided on the sliding plate 203 between every two ball grooves 204. Steel balls 12 are rolled in the ball grooves 204. A sub-plate 13 is fixedly connected to one side of the sliding plate 203. A limit 206 is fixedly connected to one end of the sliding plate 203. A rotating shaft 107 is fixedly connected to one end of the fixed plate 104. A locking pin 3 is rotatably connected to the rotating shaft 107.

[0019] like Figure 6As shown, the locking pin 3 has a shaft hole 301 that is rotatably connected to the rotating shaft 107. The locking pin 3 also has an elongated hole 302. Two sliding shafts 303 are fixedly connected along the length of the elongated hole 302. A locking plate 305 is slidably connected to each sliding shaft 303. A buckle 3051 is fixedly connected to one end of the locking plate 305, abutting against the limit 206. A lever 3052 is fixedly connected to the other end of the locking plate 305. A spring 304 is nested around the sliding shaft 303. The spring 304 has high elasticity and requires force to pull, its purpose being to prevent the brake tube from moving during installation. One end of the spring 304 abuts against the locking pin 3, and the other end abuts against the locking plate 305. Through the stretching of the spring 304, the buckle 3051 abuts against the limit 206, fixing the brake tube inside this invention and facilitating its installation.

[0020] A handle 101 is also fixedly connected to the fixing frame 1 to better clamp the brake hard tube of this utility model. The liquid tube groove 106, liquid tube groove 205 and liquid tube groove 3 1302 in this utility model need to be filled with grease to facilitate the rotation of the steel ball, so as to facilitate the entry of the brake hard tube and better limit the brake hard tube.

[0021] Working process: Multiple brake hard tubes are placed between the fixed plate 104 and the movable clamping frame 2. Bolt 4 or bolt 11 is turned using a wrench (electric wrench). Turning bolt 11 causes bevel gear 10, which in turn rotates, driving bevel gear 9 to rotate. Shaft 8, which in turn rotates gear 7, drives gear 6, which in turn rotates lead screw 5. Lead screw 5 then moves the movable clamping frame 2 to clamp the brake hard tubes. Steel balls 12 on the fixed plate 104 and sliding plate 203 provide limit positions. Once the desired position is reached, the movable clamping plate 305 secures the latch 3051 to the limit position 206. The brake hard tubes are fixed to the vehicle body using a wrench. Alternatively, turning lead screw 5 between bolts 4 moves the movable clamping frame 2 to clamp the brake hard tubes.

[0022] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
