[0028] Refer to the instruction manual Figure 1-5 The utility model provides a front cover lock, including a lock body 1, the lock body 1 includes a lock rod 101, and the lock rod 101 is set to be inclined, and both ends of the lock rod 101 are fixed with a rounded corner connecting part 102, and the bottom ends of the two rounded corner connecting parts 102 are fixed with an inclined connecting rod 103, and the bottom ends of the two inclined connecting rods 103 are fixed with a rounded corner connecting part 2 104, and the bottom ends of the two rounded corner connecting parts 2 104 are fixed with an inclined connecting rod 2 105. The bottom ends of the two inclined connecting rods 105 are fixed with rounded connecting parts 106. The bottom ends of the two rounded connecting parts 106 are fixed with vertical rods 107. The outer walls of the two vertical rods 107 are fixed with limiting rings 108. The locking rod 101, the rounded connecting part 102, the inclined connecting rod 103, the rounded connecting part 104, the inclined connecting rod 105, the rounded connecting part 106, the vertical rods 107 and the limiting rings 108 are integrally formed.

[0029] The locking rod 101, the rounded corner connecting portion 102, the rounded corner connecting portion 2 104, the rounded corner connecting portion 3 106, the tilted connecting rod 1 103, the tilted connecting rod 2 105, the vertical rod 107 and the limiting ring 108 are all made of low carbon steel. The use of low carbon steel as a material not only ensures strength but also facilitates processing and manufacturing of the locking rod 101, the rounded corner connecting portion 1 102, the rounded corner connecting portion 2 104, the rounded corner connecting portion 3 106, the tilted connecting rod 1 103, the tilted connecting rod 2 105, the vertical rod 107 and the limiting ring 108;

[0030] The outer wall surfaces of the locking rod 101, the rounded corner connecting part 102, the rounded corner connecting part 2 104, the rounded corner connecting part 3 106, the inclined connecting rod 103, the inclined connecting rod 2 105, the vertical rod 107 and the limiting ring 108 are coated with a wear-resistant coating to improve the wear resistance and service life of the locking rod 101, the rounded corner connecting part 102, the rounded corner connecting part 2 104, the rounded corner connecting part 3 106, the inclined connecting rod 103, the inclined connecting rod 2 105, the vertical rod 107 and the limiting ring 108;

[0031] The outer side wall surfaces of the two limiting rings 108 are processed with multiple protrusions 6 to improve the stability between the limiting rings 108 and the front cover.

[0032] When in use, first fix the two vertical rods 107 to the front hood. When the front hood is closed, the locking rod 101 is firmly locked with the lock on the vehicle body, thereby ensuring the security of the front hood. Since the locking rod 101 is tilted, it is not easy to be unlocked when the locking rod 101 is locked with the lock, thereby improving the security of the front hood. In addition, a lock body 1 can be provided on each side of the bottom of the front hood to balance the two sides of the front hood and prevent it from tilting. At the same time, the sealing between the front hood and the front of the vehicle can be greatly improved.

[0033] The locking rod 101, the first rounded connecting portion 102, the second rounded connecting portion 104, the third rounded connecting portion 106, the first tilted connecting rod 103, the second tilted connecting rod 105, the vertical rod 107 and the limiting ring 108 are all made of low-carbon steel.

[0034] Moreover, the outer wall surfaces of the locking rod 101, the rounded corner connection part 1 102, the rounded corner connection part 2 104, the rounded corner connection part 3 106, the inclined connecting rod 1 103, the inclined connecting rod 2 105, the vertical rod 107 and the limiting ring 108 are coated with wear-resistant coating, which has good wear resistance, thereby improving the wear resistance of the locking rod 101, the rounded corner connection part 1 102, the rounded corner connection part 2 104, the rounded corner connection part 3 106, the inclined connecting rod 1 103, the inclined connecting rod 2 105, the vertical rod 107 and the limiting ring 108.

[0035] Refer to the instruction manual Figure 1-5 The bottom ends of the two vertical rods 107 are each provided with an insulation sleeve 2, the top of the insulation sleeve 2 is in contact with the bottom end of the limiting ring 108, and is used to provide insulation between the vertical rod 107 and the front cover. The two insulation sleeves 2 are made of polytetrafluoroethylene to make the insulation sleeve 2 have a high thermal conductivity;

[0036] Furthermore, a plurality of annular protrusions 3 are machined on the inner wall surfaces of both thermal insulation sleeves 2. The plurality of annular protrusions 3 are evenly distributed from top to bottom on the inner wall surfaces of the thermal insulation sleeves 2. The plurality of annular protrusions 3 make the inner wall surfaces of the thermal insulation sleeves 2 uneven, thereby improving the stability of the thermal insulation sleeves 2 installed on the vertical rods 107. At the same time, the thermal insulation sleeves 2 can be pulled out for replacement.

[0037] Moreover, a heat insulation board 4 is fixedly provided at the bottom end of the two heat insulation sleeves 2. The heat insulation board 4 is a glass fiber board. The use of the heat insulation board 4 can further play a role of non-heat conduction. The outer walls of the two heat insulation sleeves 2 are both sleeved with a sealing ring 5.

When the vertical rod 107 is installed, the sealing ring 5 is used to seal between the limit ring 108 and the front machine cover, which can not only play a dust-proof role, but also play a heat-insulating role.

[0038] By arranging a heat-insulating sleeve 2 on both vertical rods 107, the heat-insulating sleeve 2 is made of polytetrafluoroethylene, which has very low thermal conductivity, and thus can reduce the heat conducted to the lock body 1, and avoid the high temperature of the lock body 1 affecting its wear resistance, and an insulation board 4 is arranged at the bottom of the heat-insulating sleeve 2, and a sealing ring 5 is arranged on the outer wall of the heat-insulating sleeve 2. The heat-insulating board 4 is made of glass fiber board and has non-thermal conductivity, and the sealing ring 5 is made of butyl rubber, which also has non-thermal conductivity. Therefore, the heat-insulating board 4, the sealing ring 5 and the heat-insulating sleeve 2 cooperate to play a heat-insulating role between the lock body 1 and the front hood, thereby improving the service life of the lock body 1.

[0039] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
