DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0023] Reference Figures 1 to 3The utility model provides a cylinder lifting mechanism in an example, comprising a fixed base plate 100, a lifting cover plate 110, a cylinder mounting plate 120, a cylinder 130, a guide support plate 140, a cam follower 150, a sliding assembly 170 and a connecting plate 160. The cylinder mounting plate 120 and the guide support plate 140 are fixed on the fixed base plate 100, one end of the cylinder 130 is hinged on the cylinder mounting plate 120 through a second hinge seat 280, and the other end of the cylinder 130 is hinged on the connecting plate 160 through a first hinge seat 270. The cam follower 150 is arranged on the connecting plate 160, and the connecting plate 160 is slidably connected to the lifting cover plate 110 in a horizontal direction through the sliding assembly 170. A guide assembly 180 is arranged between the fixed base plate 100 and the lifting cover plate 110. The guide assembly 180 is arranged between the fixed base plate 100 and the lifting cover plate 110. 0 is used to guide the lifting cover plate 110 to move in the vertical direction. The guide support plate 140 is provided with a guide groove 190. The cam follower 150 moves along the track of the guide groove 190. The cylinder 130 drives the connecting plate 160 to move, thereby driving the cam follower 150 to rise and fall along the track of the guide groove 190. The connecting plate 160 drives the lifting cover plate 110 to rise and fall. At the same time, the guide assembly 180 can limit the movement of the lifting cover plate 110 in the vertical direction. The connecting plate 160 and the lifting cover plate 110 slide relative to each other under the action of the sliding assembly 170, thereby realizing the conversion of horizontal movement into vertical lifting movement. The cylinder 130 is not limited by the vertical space, which is convenient for debugging. Moreover, the cam follower 150 is self-locking when it is at the top of the guide groove 190, avoiding safety hazards caused by equipment failure.

[0024] Furthermore, the sliding assembly 170 includes a sliding rail 200 and a sliding block 210 , and the sliding block 210 is slidably connected to the sliding rail 200 .

[0025] It can be understood that by setting the slide rail 200 and the slider 210, when the cylinder 130 drives the cam follower 150 to rise and fall along the trajectory of the guide groove 190, the slide rail 200 and the slider 210 slide relative to each other, and at the same time, the connecting plate 160 and the lifting cover plate 110 slide relative to each other, thereby achieving the lifting cover plate 110 can be lifted and lowered in the vertical direction.

[0026] It should be noted that the slide rail 200 can be set on the connecting plate 160 or on the lifting cover plate 110 . In this embodiment, the slide rail 200 is set on the connecting plate 160 .

[0027] Specifically, when the slide rail 200 is disposed on the connecting plate 160 , the slider 210 is disposed on the lifting cover plate 110 ; when the slide rail 200 is disposed on the lifting cover plate 110 , the slider 210 is disposed on the connecting plate 160 .

[0028] Furthermore, the guide assembly 180 includes a guide rod 220 and a guide sleeve 230 sleeved on the outer periphery of the guide rod 220, the guide sleeve 230 is vertically fixed to the fixed base plate 100, the top end of the guide rod 220 is fixedly connected to the lifting cover plate 110, and the bottom end of the guide rod 220 passes through the fixed base plate 100. Specifically, four guide sleeves 230 are provided, and the four guide sleeves 230 are respectively fixed at the four corners of the top of the fixed base plate 100. Correspondingly, four guide rods 220 are provided, and the top ends of the four guide rods 220 are respectively fixed at the four corners of the bottom of the lifting cover plate 110. When the lifting cover plate 110 is lifted or lowered, the lifting cover plate 110 drives the four guide rods 220 to slide respectively along the length direction of the four guide sleeves 230, thereby preventing the lifting cover plate 110 from being skewed, and further limiting the vertical movement of the lifting cover plate 110.

[0029] Furthermore, the guide sleeve 230 is a linear bearing, and the cooperation between the guide rod 220 and the linear bearing can reduce the wear of the guide rod 220, thereby increasing the service life of the guide rod 220.

[0030] Furthermore, two guide support plates 140 are provided, and follower fixing plates 290 are respectively provided on both sides of the connecting plate 160. The cam follower 150 is installed on the outside of the follower fixing plate 290. The cam followers 150 arranged on both sides of the connecting plate 160 can be evenly stressed, so that the cam followers 150 can move smoothly along the trajectory of the guide groove 190, thereby improving the stability of the entire structure.

[0031] Furthermore, a guide positioning plate 240 is provided on the fixed base plate 100, and two guide support plates 140 are respectively fixed on both sides of the guide positioning plate 240. The two guide support plates 140 can be positioned so that the two guide support plates 140 are arranged in parallel, ensuring that the cam followers 150 arranged on both sides of the connecting plate 160 can move smoothly on the corresponding guide support plates 140.

[0032] Furthermore, the guide support plate 140 is provided with two guide grooves 190, and the follower fixing plate 290 is provided with two cam followers 150. The two cam followers 150 correspond one by one to the two guide grooves 190 respectively, thereby reducing the force on each cam follower 150 and making the cylinder 130 drive the cam follower 150 to move more smoothly.

[0033] Furthermore, the top of the guide groove 190 is open, which can avoid limiting the size of the cam follower 150. Cam followers 150 of different sizes can be arranged according to different needs, thereby improving the flexibility of the mechanism.

[0034] Furthermore, the top of the guide support plate 140 is flush, and the guide groove 190 has an inclined portion 250 and a straight portion 260. The top of the inclined portion 250 is connected to the top of the guide support plate 140, and the bottom of the inclined portion 250 is connected to the straight portion 260. When the cam follower 150 moves along the trajectory of the guide groove 190, the cam follower 150 moves along the straight portion 260 and the inclined portion 250 in sequence to the top of the guide support plate 140, thereby enabling the cam follower 150 to be self-locked, thereby avoiding safety hazards caused by equipment failure.

[0035] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
