Specific embodiments
[0020] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0021] See Figures 1 to 4 , a strong support structure for a jack, including a support frame 1 and a support mechanism 2. The support mechanism 2 is installed inside the support frame 1. The support mechanism 2 includes a rotating block 201. The rotating block 201 is arranged on the front side of the support frame 1. The rear side surface of the rotating block 201 is fixedly connected with a rotating rod 202. The rear end of the rotating rod 202 passes through the front side surface of the support frame 1 and extends into the interior of the support frame 1. The rear end of the rotating rod 202 is fixedly connected with a worm 203. The rear end of the worm 203 is rotatably connected to the inner wall of the support frame 1. A rotating shaft 204 is rotatably connected inside the support frame 1. The surface of the rotating shaft 204 is fixedly connected with a worm gear 205 and a gear 206 respectively. The gear 206 is arranged above the worm gear 205. Two support blocks 207 are provided inside the support frame 1. The two support blocks 207 are symmetrically distributed inside the support frame 1 respectively. The front and rear side surfaces of the support block 207 are fixedly connected with sliders 208 respectively. Four chutes 3 are opened inside the support frame 1. The four sliders 208 are respectively slidably connected inside the four chutes 3. The side surfaces of the two support blocks 207 close to each other are fixedly connected with racks 209 respectively. The two racks 209 are both meshed with the gear 206. Receiving grooves 210 are opened inside the two support blocks 207 respectively. The two receiving grooves 210 are respectively corresponding to the two racks 209. The rack 209 is arranged inside the corresponding receiving groove 210.
[0022] When using this device to repair an automobile, by rotating the rotating block 201, under the cooperation of the rotating rod 202, the worm 203 and the worm wheel 205, the rotating shaft 204 is driven to rotate. Subsequently, under the cooperation of the gear 206, the rack 209, the sliding groove 3, the slider 208 and the roller 4, the two supporting blocks 207 are driven to move, so that the two supporting blocks 207 extend out of the supporting frame 1, increasing the area of the bottom of the overall device. This setting can increase the contact area with the ground when the device is in use, making it more conducive to dispersing the gravity of the automobile, avoiding shaking, and greatly reducing potential safety hazards. The storage grooves 210 opened on the upper surfaces of the two supporting blocks 207 facilitate the storage of the corresponding two racks 209 when the supporting blocks 207 are stored inside the supporting frame 1, which is more convenient and practical.
[0023] A total of four rollers 4 are fixedly connected to the bottom surfaces of the two supporting blocks 207, and the four rollers 4 are respectively distributed in a rectangular shape on the bottom surfaces of the two supporting blocks 207. The setting of the rollers 4 makes it more convenient for the two supporting blocks 207 to extend. Through the rollers 4, it is convenient to extend and unfold on the ground, which can reduce resistance.
[0024] A lifting mechanism 5 is installed on the upper surface of the supporting frame 1, and a turning handle 6 is installed on the right side surface of the lifting mechanism 5. The lifting mechanism 5 includes a fixed block 501, which is arranged above the supporting frame 1. Threaded columns 502 are fixedly connected to both the left and right sides of the fixed block 501. The two threaded columns 502 are symmetrically distributed on the left and right side surfaces of the fixed block 501 respectively. A threaded cylinder 503 is threadedly connected to the surface of the threaded column 502. An articulated block 504 is fixedly connected to the surface of the threaded cylinder 503. A spring 505 is sleeved on the surface of the threaded column 502, and the spring 505 is arranged between the fixed block 501 and the threaded cylinder 503. The turning handle 6 is fixedly connected to the right end of the threaded column 502 on the right side.
[0025] By rotating the turning handle 6, under the cooperation of the threaded column 502 and the threaded cylinder 503, it is convenient to drive the two articulated blocks 504 to move. The setting of the spring 505 makes the movement of the articulated block 504 smoother, so that the top plate 509 rises more stably, and the thread directions of the two threaded columns 502 are opposite.
[0026] The bottom surfaces of the two articulated blocks 504 are respectively hinged with a first articulated rod 506. The two first articulated rods 506 are symmetrically distributed on the bottom surfaces of the two articulated blocks 504 respectively. A fixing plate 507 is fixedly connected to the upper surface of the supporting frame 1. The lower ends of the two first articulated rods 506 are hinged to the upper surface of the fixing plate 507. The upper surfaces of the two articulated blocks 504 are respectively hinged with a second articulated rod 508. The two second articulated rods 508 are symmetrically distributed on the upper surfaces of the two articulated blocks 504 respectively. A top plate 509 is arranged above the fixed block 501, and the upper ends of the two second articulated rods 508 are hinged to the bottom surface of the top plate 509.
[0027] It moves through two hinge blocks 504. With the cooperation of the first hinge rod 506, the second hinge rod 508, and the fixed plate 507, the top plate 509 can be driven to rise, so as to stably support the vehicle.
[0028] Working principle: When the device is in use, place the device at a suitable position. Then, by rotating the rotating block 201, with the cooperation of the rotating rod 202, the worm 203, and the worm wheel 205, the rotating shaft 204 is driven to rotate. Subsequently, with the cooperation of the gear 206, the rack 209, the chute 3, the slider 208, and the roller 4, the two support blocks 207 are driven to move, so that the two support blocks 207 extend out of the support frame 1, increasing the contact area between the bottom area of the overall device and the ground. Then, by rotating the turning handle 6, with the cooperation of the threaded column 502 and the threaded cylinder 503, it is convenient to drive the two hinge blocks 504 to move. Subsequently, with the cooperation of the first hinge rod 506, the second hinge rod 508, the spring 505, and the fixed plate 507, the top plate 509 is driven to rise, so as to support the vehicle. The setting of the spring 505 makes the movement of the hinge block 504 more stable, and the rising of the top plate 509 more stable.
[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
