[0016] 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.

[0017] See also Figure 1-3 A cylinder protection device for a body-in-white clamp is arranged on a cylinder 1 and includes a shell 3. An assembly area 33 is arranged on the top of the shell 3. A mounting hole 34 is arranged on the side of the assembly area 33. A first through hole 31 penetrates through the lower part of the side of the shell 3 and a second through hole 32 penetrates through the upper part. A pushing member 35 is arranged on the side of the shell 3 away from the cylinder 1.

[0018] During assembly, the operator places the shell 3 on the cylinder 1 through the assembly area 33 in a sleeve manner with one hand, and the cylinder 1 is connected to the clamp 2. The cylinder 1 and the clamp 2 are installed and fixed through the base 4, so that the shell 3 completely covers the side of the cylinder 1. The operator twists the pusher 35 with the other hand, so that the pusher 35 adjusts the contact surface between the assembly area 33 of the shell 3 and the front cover 5 to ensure that the assembly area 33 will not be tilted with the front cover 5 as a fulcrum due to unbalanced force to form an angle, which affects the assembly rate. Then the operator uses bolts to pass The mounting hole 34 connects and fixes the shell 3 and the front end cover 5, thereby completing the protection of the cylinder 1, preventing the cylinder 1 from being hit by other substances and splashing welding slag, and improving the service life of the cylinder 1. Finally, the operator can not only debug the air intake regulating valve and the air outlet regulating valve of the cylinder 1 through the first through hole 31 and the second through hole 32, but also use the first through hole 31 and the second through hole 32 on both sides to install limit rods for auxiliary limiting. The limit rod can be a spring rod, but is not limited to this, thereby enhancing the assembly accuracy of the shell 3 and the cylinder 1 and improving the assembly efficiency.

[0019] In some embodiments, the assembly area 33 includes an arc-shaped portion 331 and a through slot 332 , and the arc-shaped portion 331 is in communication with the through slot 332 .

[0020] When the operator fixes the cylinder 1 to the shell 3, the operator uses the through groove 332 of the shell 3 to pre-place the telescopic part of the cylinder 1 into the arc-shaped part 331 to play a guiding role. Then the shell 3 is controlled to move downward so that the assembly area 33 contacts the cylinder 1. At this time, the connection between the telescopic part of the cylinder 1 and the front cover 5 enters the arc-shaped part 331 and is limited by the through groove 332 and cannot be laterally offset, thereby preventing the shell 3 from falling and affecting the installation. Finally, the shell 3 is placed on the cylinder 1, and then the shell 3 and the cylinder 1 are fixed together by installing screws to complete the assembly.

[0021] In some embodiments, four mounting holes 34 are provided, and the four mounting holes 34 surround the assembly area 33 .

[0022] The four mounting holes 34 can not only improve the firmness of the connection between the shell 3 and the cylinder 1, so that the shell 3 will not loosen and fall due to collision when protecting the cylinder 1, thereby enhancing the protection capability of the shell 3. At the same time, the operator can use at least two mounting screws to fix the shell 3 and the cylinder 1 together through the diagonal mounting holes 34, which can cope with the situation of lack of mounting screws and can be used in an emergency.

[0023] In some embodiments, the pusher 35 includes a nut 351 and a bolt 352 . Two nuts 351 are provided, and the two nuts 351 are welded to the inner and outer sides of the shell 3 respectively. The bolt 352 penetrates the shell 3 and is connected to the nut 351 .

[0024] When the operator places the shell 3 on the cylinder 1, the operator holds the assembly area 33 with one hand to ensure that the assembly area 33 is always in contact with the cylinder 1, and controls and tightens the bolt 352 with the other hand. When the operator tightens the bolt 352, the bolt 352 is restricted by the two nuts 351 and moves toward the cylinder 1, exerting a thrust on the cylinder 1, so that the assembly area 33 and the cylinder 1 continuously adjust the contact surface until the assembly area 33 and the cylinder 1 are close to each other without tilting and forming an angle, ensuring that the subsequent operator will not encounter difficulty in alignment when fixing the shell 3 and the cylinder 1 through the mounting hole 34, thereby speeding up the installation speed; the pusher 35 is located at the upper and lower parts of the shell 1, and can adapt to cylinders 1 of different sizes, thereby ensuring that cylinders 1 of different sizes can be quickly connected and fixed to the shell 3, thereby improving assembly efficiency.

[0025] In some embodiments, a butterfly wing is disposed at one end of the bolt 352 away from the nut 351 .

[0026] When the operator turns the bolt 352 to adjust the fit between the housing 3 and the cylinder 1, the butterfly wing can increase the contact area between the operator's fingers and the bolt 352, increase the force on the bolt 352, and make it more convenient and quick for the operator to turn the bolt 352 for quick adjustment.

[0027] In some embodiments, the side of the housing 3 away from the cylinder 1 is configured to be arc-shaped.

[0028] The arc shape provided on one side of the shell 3 can increase the surface tension of the shell 3, and can relieve part of the impact force when hit by flying solid impurities, so that the solid impurities cannot cause large-scale and high-intensity damage to the shell 3, thereby enhancing the protection strength of the shell 3 to the cylinder 1. At the same time, the arc shape of the shell 3 fits the shape of the cylinder 1, which can not only prevent the shell 3 from causing accidental injury to the operator, but also save space and protect the cylinder 1 to the greatest extent.

[0029] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
