[0002] In a car engine, the valve action timing and state must be consistent with the state and timing of the piston movement. Since the crankshaft and camshaft are not on the same axis, a transmission system is needed to connect them. This transmission system usually consists of two gears and a chain or belt. These two gears are timing gears. There will be specific marks on the timing gears. After correctly installing the chain or belt according to these marks, the timing and state of the valve action can be ensured to be accurate.

[0003] The timing gear cover is located on the cylinder block or cylinder head of the engine and covers the timing gear and related transmission mechanism. The main function of the timing gear cover is to provide a closed space to protect the timing gear and other transmission components from the invasion of dust, dirt, moisture and other external impurities, so as to ensure that the timing gear and its transmission mechanism operate in a clean and dry environment, thereby improving its service life and reliability.

[0004] When installing the timing gear cover, in order to ensure that the gear cover is stable and correctly aligned, the staff will generally align the timing gear cover first, and then support it while fastening it with bolts. However, the staff needs to divide their attention between the supporting object and the fixing bolts, which can easily affect the smoothness and speed of the operation. In addition, the object cannot be completely fixed by supporting it with one hand, causing the object to shake or shift during the fixing process. For this reason, we propose a timing gear cover.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 7 , Embodiment 1

[0026] The utility model provides a technical solution: a timing gear chamber cover, comprising a chamber cover body 1; further comprising a connecting hole 2, the connecting hole 2 being located on the inner wall of the chamber cover body 1; a docking mechanism 3, the docking mechanism 3 being located on the inner wall of the connecting hole 2, and the docking mechanism 3 being able to be simultaneously inserted into a plurality of screw holes on the surface of the cylinder head;

[0027] When in use, the staff sticks the chamber cover body 1 on the surface of the cylinder head and makes the connecting holes 2 correspond to the screw holes of the cylinder head one by one, and then temporarily fixes the chamber cover body 1 on the surface of the cylinder head through the provided docking mechanism 3. The staff does not need to support it with their hands when installing the bolts, which improves the smoothness and speed of the operation. When the staff installs the bolts, the docking mechanism 3 automatically releases the connection with the screw holes at this position of the cylinder head to facilitate the insertion of the bolts into the screw holes at this position, while the docking mechanisms 3 at other positions still keep the chamber cover body 1 connected to the cylinder head, thereby improving the stability of the chamber cover body 1 during the fixing process.

[0028] The docking mechanism 3 includes a sliding column 30 located on the inner wall of the connecting hole 2, the sliding column 30 is slidably connected to the inner wall of the connecting hole 2, a bolt hole 31 is opened on the inner wall of the sliding column 30, a driving member 32 for simultaneously driving a plurality of sliding columns 30 to move is provided on the inner wall of the chamber cover body 1, and a connecting member 33 for connecting the sliding column 30 to the screw hole of the cylinder head is provided at the end of the sliding column 30;

[0029] When the docking mechanism 3 is working, the staff controls multiple sliding columns 30 to approach the cylinder head through the driving member 32, and inserts the connecting member 33 into the screw hole of the cylinder head. When the staff puts on the bolt, the staff first inserts the bolt into the bolt hole 31 of the sliding column 30, and then tightens the bolt. The friction between the bolt and the inner wall of the sliding column 30 drives the sliding column 30 to rotate, so that the sliding column 30 and the driving member 32 are released, and the sliding column 30 is reset. The movement of the sliding column 30 drives the connecting member 33 to slide out of the screw hole of the cylinder head, and as the bolt is continued to be tightened, the bolt passes through the sliding column 30 and is screwed into the screw hole on the surface of the cylinder head, thereby completing the installation of the bolt here, and the connecting members 33 at other positions still keep the chamber cover body 1 connected to the cylinder head, thereby improving the stability of the chamber cover body 1 during the fixing process.

[0030] The driving member 32 includes a plurality of connecting plates 34 slidably connected to the inner wall of the chamber cover body 1, the connecting plate 34 is located between two adjacent sliding columns 30, a plurality of push rods 35 are threadedly connected to the inner wall of the chamber cover body 1, the push rods 35 are rotatably connected to the inner wall of the connecting plate 34, a stopper 36 is provided at one end of the sliding column 30 close to the connecting plate 34, and a reset member 37 is provided on the outer side of the sliding column 30;

[0031] When the driving member 32 is working, the staff uses a tool such as a screwdriver to screw the push rod 35, and the push rod 35 and the connecting plate 34 rotate relative to each other. Since the push rod 35 rotates and moves inward on the inner wall of the chamber cover body 1, the push rod 35 pushes the connecting plate 34 to move toward the cylinder head. The connecting plate 34 drives the sliding column 30 to move toward the cylinder head through the limit member 36. When the staff releases the limit member 36, the reset member 37 pushes the sliding rod to move outward to cooperate with the connecting member 33 to slide out of the inner wall of the screw hole of the cylinder head.

[0032] The limiting member 36 includes a limiting block 38 fixedly connected to the connecting plate 34. A limiting groove 39 slidably connected to the limiting block 38 is provided on the surface of the sliding column 30. The limiting groove 39 is divided into a clamping end 310 and a sliding end 311.

[0033] When the user turns the bolt, the bolt drives the sliding rod to rotate through the friction with the inner wall of the bolt hole 31, so that the limit block 38 and the limit slot 39 move relative to each other, and the limit block 38 moves from the clamping end 310 of the limit slot 39 to the sliding end 311. When the reset member 37 pushes the sliding column 30 to move outward, the limit block 38 slides on the sliding end 311 of the limit slot 39, thereby releasing the limit of the sliding column 30 at this position, and as the bolt continues to rotate, the friction between the bolt and the inner wall of the bolt hole 31 will drive the sliding rod to continue to rotate, so that the limit block 38 is stuck at the end of the sliding end 311. At this time, the bolt will no longer drive the sliding rod to rotate, and the downward force of the bolt on the sliding rod will not drive the sliding rod to move downward again.

[0034] The reset member 37 includes a sliding block 312 fixedly connected to the outer side of the sliding column 30, a sliding groove 313 slidably connected to the sliding block 312 is provided on the inner wall of the chamber cover body 1, a sponge pad 314 is fixedly connected to the inner wall of the sliding groove 313, and the sponge pad 314 is fixedly connected to the sliding block 312;

[0035] When the limit block 38 is located at the clamping end 310 of the limit groove 39, when the connecting plate 34 moves toward the cylinder head, it will drive the sliding column 30 to move toward the cylinder head. The sliding column 30 drives the sliding block 312 to slide along the inner wall of the sliding groove 313, so that the sliding block 312 squeezes the sponge pad 314. When the limit block 38 moves to the sliding end 311 of the limit groove 39, the sponge pad 314 in a compressed state pushes the sliding block 312 to reset, and the sliding block 312 drives the sliding column 30 to reset, so that the connecting piece 33 slides out of the screw hole of the cylinder head.

[0036] The connecting piece 33 includes a rubber ring 315 fixedly connected to the end of the sliding column 30. The outer diameter of the rubber ring 315 is the same as the inner diameter of the screw hole of the cylinder head. Since the outer diameter of the rubber ring 315 is the same as the inner diameter of the screw hole on the surface of the cylinder head, when the sliding column 30 moves toward the cylinder head, the sliding column 30 drives the rubber ring 315 to be inserted into the screw hole of the cylinder head. Multiple rubber rings 315 are inserted into the cylinder head at the same time to cooperate with the temporary support of the chamber cover body 1. When the staff inserts the bolt into the sliding column 30, as the bolt rotates, the clamping connection between the sliding column 30 and the connecting plate 34 is released, and the sponge pad 314 in a compressed state pushes the sliding column 30 to reset. The sliding column 30 drives the rubber ring 315 to slide out of the inner wall of the screw hole of the cylinder head. After the bolt passes through the rubber ring 315, due to the elasticity of the rubber ring 315 itself, it will be propped outward by the bolt to cooperate with the bolt to enter the screw hole of the cylinder head.

[0037] Embodiment 2

[0038] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that two push rods 35 are provided and distributed on both sides of the chamber cover body 1, so as to facilitate inserting the rubber rings 315 located on both sides of the chamber cover body 1 into the screw holes of the cylinder head, thereby completing the temporary fixation of the chamber cover body 1 and avoiding too many connecting plates 34, which causes the push rods 35 to fail to drive all the connecting plates 34 to move together.
