DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 , an engine front cover mounting structure, comprising a mounting plate 1 and a housing 2, a plurality of rectangular blocks 3 are fixedly mounted on the mounting plate 1, a plurality of rectangular blocks 3 are provided with slots on their sides, and a limiting hole connected to the slots is provided on the upper surface of the rectangular block 3;

[0022] The housing 2 is fixedly provided with mounting blocks 4 on both sides, and the surfaces of the two mounting blocks 4 are symmetrically and rotatably provided with support rods 5, and one end of the plurality of support rods 5 is rotatably provided with a clamping block 6;

[0023] An installation groove is provided on the upper surface of the clamping block 6, in which a first telescopic spring 7 is fixedly installed. A limit block 8 with a right-angle trapezoidal longitudinal section is fixedly installed at one end of the first telescopic spring 7, and the limit block 8 is vertically slidably installed in the installation groove.

[0024] When installing the front cover shell, first drive the front cover shell to move in the direction of the mounting plate 1. During the movement, multiple blocks 6 will first contact the surface of the mounting plate 1, and then the two blocks 6 on the same side of the shell body 2 will move away from each other under the action of the two support rods 5 until the two blocks 6 are respectively inserted into the slots opened by the two rectangular blocks 3. When the blocks 6 are inserted into the slots, the inclined surfaces of the limit blocks 8 installed in the mounting slots will first contact the inner walls of the slots. Under the restriction of the inclined surfaces of the limit blocks 8, the limit blocks 8 will move vertically into the mounting slots. The first telescopic spring 7 is compressed until the blocks 6 are fully inserted into the slots. The limit blocks 8 will move vertically upward under the action of the elastic force of the first telescopic spring 7, so that the limit blocks 8 are inserted into the limiting holes, thereby locking the block 6 in the slots, completing the installation of the front cover shell, abandoning the use of bolts, so that the front cover shell can be stably installed on the engine, reducing the risk of falling, and convenient for installation and disassembly, which is convenient for subsequent maintenance.

[0025] The surface of the mounting plate 1 is symmetrically provided with slide grooves, and the lower surfaces of the plurality of blocks 6 are rotatably installed with rollers 9. When the block 6 contacts the mounting plate 1, the rollers 9 rotatably installed on the block 6 will move into the slide grooves. When the block 6 moves on the mounting plate 1, the rollers 9 will roll horizontally in the slide grooves, and the friction between the block 6 and the mounting plate 1 can be reduced by the rollers 9.

[0026] A second telescopic spring 10 is provided between the two clamping blocks 6 located on the same side of the shell 2. The two ends of the second telescopic spring 10 are respectively fixedly connected to the clamping blocks 6. Under the action of the elastic force of the second telescopic spring 10, the two clamping blocks 6 tend to move closer to each other, so that the side surface of the limit block 8 is tightly attached to the inner wall of the limit hole, avoiding the limit block 8 from shaking in the limit hole, thereby preventing the clamping block 6 from shaking in the clamping groove, and improving the stability of the front cover shell installation.

[0027] An L-shaped support block 11 is fixedly installed on the upper end of the rectangular block 3. A movable hole is opened on the surface of the support block 11, and a push rod 12 is vertically slidably installed in the movable hole. When disassembly is required, the push rod 12 can be pressed to make one end of the push rod 12 contact with the limit block 8, thereby driving the limit block 8 to move into the installation groove until the limit block 8 is moved out of the limit hole. At this time, the clamping block 6 can be moved out of the clamping slot to realize the disassembly of the front cover shell, which is easy to operate.

[0028] A plurality of positioning blocks 13 are fixedly installed on the side of the shell 2, and positioning holes are opened on the surfaces of the plurality of positioning blocks 13. A plurality of positioning rods 14 are vertically fixedly installed on the surface of the mounting plate 1, and one end of the positioning rod 14 is inserted in the positioning hole. A rubber pad is fixedly sleeved on the surface of the positioning rod 14, and the rubber pad is inserted in the positioning hole. Before installing the front cover shell, one end of the plurality of positioning rods 14 is respectively inserted into the plurality of positioning holes, thereby positioning the front cover shell and ensuring that the position of the card block 6 can be aligned with the card slot. At the same time, when the positioning rod 14 and the rubber pad are inserted into the positioning hole, they are interference fit, which further improves the stability between the front cover shell and the mounting plate 1 and reduces the relative vibration between the two.

[0029] In the utility model, when installing the front cover shell, the block 6 is inserted into the slot. During the insertion process of the block 6, the inclined surface of the limit block 8 will first contact the inner wall of the slot and move into the installation slot. The first telescopic spring 7 is compressed. After the block 6 is completely inserted into the slot, the limit block 8 will be inserted into the limit hole under the action of the elastic force of the first telescopic spring 7, thereby locking the block 6 in the slot, completing the installation of the front cover shell, abandoning the use of bolts, so that the front cover shell can be stably installed on the engine, reducing the risk of falling, and convenient installation and disassembly, which is convenient for subsequent maintenance.

[0030] In general, in view of the technical problem that: when the engine is running, it will produce violent vibrations. During long-term vibrations, the bolts will become loose, causing the front cover to be in danger of falling off. At the same time, the bolt connection method is not only time-consuming and labor-intensive, but also inconvenient for regular maintenance of the engine; adopting a technical solution: through the mutual cooperation of the mounting block 4, the support rod 5, the rectangular block 3, the clamping block 6, the first telescopic spring 7 and the limit block 8, the front cover can be conveniently installed on the engine; because the implementation process of the technical solution is: when installing the front cover, the clamping block 6 is inserted into the clamping slot, and the clamping block During the insertion process, the inclined surface of the limit block 8 will first contact the inner wall of the card slot and move into the installation slot, and the first telescopic spring 7 will be compressed. After the card block 6 is fully inserted into the card slot, the limit block 8 will be inserted into the limit hole under the action of the elastic force of the first telescopic spring 7, thereby locking the card block 6 in the card slot and completing the installation of the front cover shell; therefore, the technical problem can be solved, and the technical effect achieved is: abandoning the use of bolts, so that the front cover shell can be stably installed on the engine, reducing the risk of falling, and convenient installation and disassembly, which is convenient for subsequent maintenance.
