[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] An integrally formed refrigeration compressor cylinder head, such as Figures 1 to 6 As shown, it includes a cover body 100, and both ends of the cover body 100 are equipped with locking components 200;

[0027] The locking assembly 200 includes a side plate 210 rotatably mounted on the end face of the cover body 100, a bolt 220 rotatably mounted on the center of the end face of the cover body 100 near the top and extending into the side plate 210, a longitudinal strip 240 is provided on the inner side of the side plate 210 near the bottom end, a longitudinal strip 240 is movably mounted inside the longitudinal strip 240 and sleeved on the outer wall of the bolt 220, a transverse strip 250 is provided at the bottom end of the cover body 100 near the front and rear surfaces, two sets of square strips 252 are provided at the top end of the transverse strip 250 extending into the bottom end of the cover body 100, a notch 251 is provided on the outer wall of the transverse strip 250 near the bottom, and two sets of protruding plates 241 extending into the notch 251 are fixed to the side wall of the longitudinal strip 240;

[0028] The bottom end of the cover body 100 is covered with a cylinder body 300, and the outer wall of the cylinder body 300 is fixed with an outer edge frame 310 that is engaged with the locking assembly 200. The tops of the horizontal strips 250 and the vertical strips 240 are in conflict with the bottom end of the outer edge frame 310.

[0029] Before installing the cover 100, it is necessary to rotate the two sets of side panels 210 around the rotation point to the side away from the cover 100. Then, the cover 100 can be sleeved on the top position of the cylinder 300, and its outer frame 310 can be in contact with the bottom end of the cover 100. Then, the side panels 210 are rotated back. At this time, the longitudinal strips 240 are located below the outer frame 310. Use a tool to apply external force to the bolts 220 to rotate them. At this time, the longitudinal strips 240 will rise due to the rotation of the bolts 220 until they are tightly fitted with the bottom of the outer frame 310, thereby making the cover 100 and the top of the cylinder 300 tightly docked.

[0030] As the longitudinal slats 240 rise, the protruding plates 241 on one side rise in the notches 251 and exert an upward force on the transverse slats 250. The transverse slats 250 will also rise, and the square bars 252 on the top will retract into the cover body 100 and approach the outer frame 310 until the transverse slats 250 are in contact with the bottom of the outer frame 310 and fit tightly together, thereby fitting with the bottom of the outer frame 310 from multiple directions, making the cover body 100 and the cylinder body 300 tightly and firmly connected, while reducing the number of rotations of the bolts 220, thereby achieving the purpose of convenient and efficient pressing of the cover body 100.

[0031] Please refer to Figure 1 and Figure 2 A notch is provided at the top center of the side plate 210 at the contact position of the bolt 220 , and a support piece 221 is provided in the notch and is sleeved on the outer wall of the bolt 220 . The support piece 221 is fixedly connected to the end face of the cover body 100 .

[0032] The side plate 210 is ensured to rotate without being constrained by the support piece 221 , so that the cover 100 can be normally assembled and disassembled, and the support piece 221 provides a fixed-point rotation and stability effect for the bolt 220 .

[0033] Please refer to Figure 5 A receiving groove 101 is provided at the bottom end of the cover 100 where it contacts the square bar 252. Two sets of guide grooves 102 are provided on the inner wall of the receiving groove 101. Two sets of guide posts 253 that slide in the guide grooves 102 are fixed to the front and rear outer walls of the square bar 252.

[0034] When the square bar 252 is dragged and lifted by the transverse slat 250 , the guide post 253 is tilted and lifted under the constraint of the guide groove 102 , so that the transverse slat 250 is lifted and moved closer to the inside.

[0035] A threaded hole 242 is formed at the position where the longitudinal strip 240 contacts the bolt 220 , and guide bars fixed to the upper and lower inner walls of the travel groove 230 are provided on both sides of the threaded hole 242 .

[0036] The threaded hole 242 can be used to make it rise in the travel groove 230 as the bolt 220 rotates, while the two sets of guide square bars and longitudinal strips 240 will not rotate as the bolt rotates, so that it rises linearly along a preset trajectory.

[0037] The cover 100 is made of aluminum alloy die-casting.

[0038] When in use, before installing the cover 100, it is necessary to move the two sets of side panels 210 around the rotation point to the side away from the cover 100, and then the cover 100 can be sleeved on the top position of the cylinder 300, so that its outer frame 310 contacts the bottom end of the cover 100, and then the side panels 210 are rotated back. At this time, the longitudinal strips 240 are located below the outer frame 310, and a tool is used to apply external force to the bolts 220 to rotate them. At this time, the longitudinal strips 240 will rise due to the rotation of the bolts 220 until they are tightly fitted with the bottom of the outer frame 310, so that the cover 100 and the top of the cylinder 300 are tightly connected;

[0039] As the longitudinal slats 240 rise, the protruding plates 241 on one side rise in the notches 251 and exert an upward force on the transverse slats 250. The transverse slats 250 will also rise, and the square bars 252 on the top will retract into the cover body 100 and approach the outer frame 310 until the transverse slats 250 are in contact with the bottom of the outer frame 310 and fit tightly together, thereby fitting with the bottom of the outer frame 310 from multiple directions, making the cover body 100 and the cylinder body 300 tightly and firmly connected, while reducing the number of rotations of the bolts 220, thereby achieving the purpose of convenient and efficient pressing of the cover body 100.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
