[0002] An engine bracket is a tool used to fix and support an engine during engine maintenance and assembly, and includes a movable bracket and a connecting part rotatably connected to the bracket.

[0003] When repairing or assembling the engine, the engine will be fixed at the front side of the connection part, causing the center of gravity of the engine bracket to shift forward. Therefore, the existing bracket, such as the patent document disclosed in the authorization announcement number CN206883593U, needs to be provided with an auxiliary support leg extending forward on both sides thereof, so that the overall center of gravity of the engine bracket after the engine is fixed still falls within the bracket to ensure the stability of the overall use of the engine bracket. Since the space in the repair workshop is often limited, the floor space of the bracket will increase significantly after the auxiliary support legs are added. Therefore, in order to facilitate the storage of the engine bracket, the auxiliary support legs will be set to a foldable or detachable structure. When the engine bracket is not in operation, the auxiliary support legs can be folded upward or removed to reduce the floor space.

[0004] However, in actual use, if the auxiliary support legs are of a folding structure, the two auxiliary support legs need to be folded upward one by one and then positioned; if they are of a detachable structure, the two auxiliary support legs need to be removed one by one and then stored and positioned, which are inconvenient in use and therefore require further improvement.

[0029] The base frame 21 includes a crossbeam 211 and a longitudinal beam 212. The crossbeam 211 is extended left and right, and has support wheels at the bottom of the left and right ends of the crossbeam 211. The longitudinal beam 212 is extended front and back, and the rear end of the longitudinal beam 212 is fastened to the middle part of the crossbeam 211 through a connecting plate and corresponding bolts, and the bottom of the front end has support wheels. The longitudinal beam 212 is a U-shaped beam with an opening facing upward.

[0030] The auxiliary support assembly 22 includes a support leg 221 , a support foot 223 and a movable sleeve 222 .

[0031] The support leg 221 is extended forward and backward, and the rear end of the support leg 221 is located in the U-shaped groove of the longitudinal beam 212, and is hinged to the longitudinal beam 212 through corresponding axes and holes. The front end can be flipped up and down to form an expanded position and a folded position of the support leg 221 relative to the base frame 21. A first positioning structure for positioning the support leg 221 in the expanded position and the folded position is provided between the rear end of the support leg 221 and the longitudinal beam 212 of the base frame 21.

[0032] The movable sleeve 222 is disposed on the supporting leg 221 and can move forward and backward on the supporting leg 221 . A second positioning structure for positioning the movable sleeve 222 is disposed between the front end of the supporting leg 221 and the movable sleeve 222 .

[0033] There are two support legs 223 , which are respectively fixed on the left and right sides of the moving sleeve 222 and are arranged perpendicular to the support legs 221 . A universal wheel 2231 is arranged on one end of the support leg 223 facing away from the moving sleeve 222 .

[0034] Specifically, the first positioning structure includes a first positioning pin 32, a folding position positioning hole 31 provided on the longitudinal beam 212, an unfolding position positioning hole, and a first positioning hole provided on the support leg 221. The folding position positioning hole 31 is located on the upper side of the hinged position between the support leg 221 and the longitudinal beam 212, and the unfolding position positioning hole is located on the front side of the hinged position between the support leg 221 and the longitudinal beam 212. When the support leg 221 is in the folded position, the folding position positioning hole 31 is connected to the first positioning hole for the first positioning pin 32 to be inserted and positioned; when the support leg 221 is in the unfolded position, the folding position positioning hole 31 is connected to the first positioning hole for the first positioning pin 32 to be inserted and positioned; Figure 1 As shown, the deployment position positioning hole is butted against the first positioning hole for the first positioning pin 32 to be inserted and positioned.

[0035] The movable sleeve 222 has a slideway 2221 that cooperates with the support leg 221, and each inner wall of the slideway 2221 has rollers 6 that fit with the four sides of the support leg 221. There are two rollers 6 on each inner wall, and they are distributed along the extension direction of the slideway 2221 to facilitate the movable sleeve 222 to move on the support leg 221.

[0036] The movable sleeve 222 has slots 2222 on both left and right ends. The support legs 223 are inserted into the slots 2222 at one end facing the movable sleeve 222 and are fastened by bolts to achieve a detachable connection.

[0038] A limiting plate 2211 is fixed at the front end of the supporting leg 221 by means of bolts. The size of the limiting plate 2211 is larger than that of the channel, which can prevent the movable sleeve 222 from accidentally sliding out of the supporting leg 221 and facilitate the positioning of the movable sleeve 222 at the front end of the supporting leg 221. That is, when the movable sleeve 222 moves forward and abuts against the limiting plate 2211, the lower positioning hole and the upper positioning hole are in a docking state.

[0039] The connecting mechanism 1 includes a column 11 , a mounting plate 13 and a positioning claw 14 .

[0040] The column 11 is vertically arranged at the connection between the cross beam 211 and the longitudinal beam 212 by welding or bolt connection. A mounting sleeve 111 is welded on the top of the column 11 , and a reinforcing plate 12 is arranged between the front side wall of the column 11 and the top of the longitudinal beam 212 .

[0041] A rotating sleeve 131 is welded on the back of the mounting plate 13 , and the mounting plate 13 is mounted on the mounting sleeve 111 through the rotating sleeve 131 . Meanwhile, the mounting plate 13 is vertically located in front of the mounting sleeve 111 , and a third positioning structure is arranged between the rotating sleeve 131 and the mounting sleeve 111 .

[0042] There are multiple positioning claws 14, and they are all installed on the front side of the mounting plate 13 for positioning the engine. In this embodiment, there are four positioning claws 14, and correspondingly, there are four waist-shaped holes 132 on the mounting plate 13 for the four positioning claws 14 to be installed. Each positioning claw 14 includes a positioning rod 141 and a positioning column 142. One end of the positioning rod 141 is fixed to the waist-shaped hole 132 of the mounting plate 13 by bolts, and the other end is for the positioning column 142 to be installed. The positioning column 142 can be inserted into the engine to position the engine. When in use, after loosening the bolts, the positioning rod 141 can be rotated and moved in the waist-shaped hole 132 to adapt to the positioning of engines of different models.

[0043] The third positioning structure includes a third positioning pin 5, an outer positioning hole opened on the mounting sleeve 111, and a plurality of inner positioning holes opened on the rotating sleeve 131 and distributed along the circumference. When the rotating sleeve 131 rotates relative to the mounting sleeve 111, the inner positioning holes at different positions are docked with the outer positioning holes for the insertion of the third positioning pin 5, thereby realizing the positioning of the mounting plate 13 at different rotation angles, so as to position the engine at different angles for easy observation and maintenance.

[0044] The connecting mechanism 1 further includes a handle 15 . The rear end of the rotating sleeve 131 is located outside the mounting sleeve 111 and has a socket 1311 for inserting the handle. The rotating sleeve 131 can be conveniently rotated through the handle 15 .

[0045] A positioning sleeve 112 is provided on the side wall of the column 11 for inserting and storing the handle 15 in a vertical state, thereby improving the convenience of storing the handle.

[0046] When the bracket is needed to position the engine, the auxiliary support assembly 22 is unfolded, and then positioned by the first positioning structure for use. When not in use, the support legs 221 and the support feet 223 are simultaneously flipped upward and folded, and then positioned by the first positioning structure, thereby saving the occupied area during storage and transportation. During the folding process, the mobile sleeve 222 and the support feet 223 can also be moved backward according to actual needs, which is convenient for flipping and folding. After the auxiliary support assembly 22 is flipped as a whole, the mobile sleeve 222 and the support feet 223 are placed in a lower position, so that the center of gravity is moved downward, thereby improving the stability of the engine bracket when placed in a folded state.
