Description

Technical Field

[0001] The utility model relates to the technical field of swing cylinders, in particular to an anti-deformation gear swing cylinder. Background Art

[0002] The gear swing cylinder converts the linear motion of the piston rod into rotational motion for output. Generally, a rack is set on the surface of the piston rod inside the gear swing cylinder, which then meshes with the gear at one end of the corresponding gear shaft to achieve motion conversion.

[0003] However, in actual use, since the interior of the oil cylinder simply meshes the rack and the gear with each other, in the absence of restrictions, the gear is prone to tilt and disengagement, which affects the meshing of the gear and the rack. At the same time, during installation, the flange rings are usually pressed against each other, so when replacing or repairing, the bolts need to be removed one by one to achieve replacement, which is not convenient. Moreover, when connecting, the lack of uniform rotation between multiple bolts can easily lead to different fixing tightness, affecting the actual fixing effect. Utility Model Content

[0004] The utility model aims to provide an anti-deformation gear swing cylinder, which solves the problems in the prior art that the gear and rack are easily shaken and separated when connected to each other, and that it is inconvenient to rotate multiple bolts when disassembling and installing.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-deformation gear swing cylinder, comprising a central tube, a rotating tube and a connecting tube, wherein the top of the central tube is connected with the rotating tube, both ends of the central tube are connected with the connecting tube, the two ends of the central tube are connected with the connecting tube through a connecting assembly, and a moving rod is provided inside the central tube;

[0006] A rotating rod is provided inside the rotating tube for rotation, and a rotating gear is sleeved inside the rotating rod;

[0007] The connecting assembly for connection includes a rotating ring and a through rod, the through rod is fixedly connected to the gear ring on one side close to the central tube, and the outer wall of the through rod close to the connecting tube is rotatably connected to a nut through a thread, the inner wall of the rotating ring is meshed with the outer wall of the gear ring, and the inner wall of the rotating ring is processed with gear teeth meshed with the outer wall of the gear ring;

[0008] Both ends of the sliding moving rod are slidably connected to the inner wall of the central tube through a push plug. The side wall of the moving rod is surrounded by a plurality of sliding grooves, and a toothed belt is arranged inside the sliding groove. The rotating gear is meshed with the toothed belt inside one of the sliding grooves.

[0009] Preferably, the push plug is inclined toward the center at a side away from the moving rod, and the push plug is slidably connected to the inner walls of the central tube and the connecting tube respectively.

[0010] Preferably, the outer walls at both ends of the central tube are provided with connecting flanges in a surrounding manner, and the outer wall of the connecting tube is provided with a mounting flange at one end close to the central tube.

[0011] Preferably, the interior of the rotating ring is rotatably connected to the outer wall of the connecting flange via a bearing, and the inner wall of the rotating ring and the mounting flange are sleeved and fitted to each other.

[0012] Preferably, the gear ring is rotatably connected to one side of the connecting flange, the nut is fixedly connected to the outer wall of the mounting flange, the through rod penetrates the interior of the connecting flange and the mounting flange respectively, and the interior of the connecting flange and the mounting flange are provided with through holes corresponding to the through rod.

[0013] Preferably, the inner side of the rotating tube close to the central tube is communicated with the inner side of the central tube, and the top of the end of the connecting tube away from the central tube is penetrated and connected with a conveying pipe.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. When in use, one side of the rotating gear is located inside the slide groove and meshes with the toothed belt, thereby realizing the restriction of the slide groove on the rotating gear, thereby limiting the separation of the rotating gear and the toothed belt, thereby avoiding deformation, and also limiting the inclination of the slide groove by the rotating gear, thereby realizing the restriction of the moving rod. At the same time, since the outer wall of the moving rod is provided with multiple slide grooves and toothed belts, when a single slide groove or toothed belt is worn, the connection between the rotating gear and the toothed belt can be released, and then the moving rod can be rotated and replaced in a different slide groove, thereby reconnecting the new toothed belt to the rotating gear without replacing the moving rod;

[0016] 2. During installation, the connecting tube can be made to correspond to one end of the center tube, so that the through rod passes through the inside of the mounting flange and is connected to the nut, and then the rotating ring can be rotated, so that the rotating ring drives the gear ring to rotate and then the through rod rotates. At the same time, since the nut and the mounting flange are fixed to each other, the through rod and the nut can be evenly connected to each other, and then the connecting tube is driven to move toward the center tube, thereby achieving a close connection with the center tube. At the same time, since multiple through rods rotate at the same time, the connection can be effectively maintained uniformly, and when disassembly is required, the rotating ring can be rotated in the reverse direction to drive the through rods to rotate in a unified reverse direction, thereby facilitating the release of the connection, and conveniently removing the obstruction of the push plug at one end of the moving rod, and facilitating replacement and rotation adjustment.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5The anti-deformation gear swing cylinder shown includes a center tube 1, a rotating tube 2 and a connecting tube 3. The rotating tube 2 is connected to the top of the center of the center tube 1, and the two ends of the center tube 1 are connected to the connecting tube 3. The two ends of the center tube 1 are connected to the connecting tube 3 through a connecting assembly 4. A moving rod 5 is penetrated inside the center tube 1; a rotating rod 201 is penetrated inside the rotating tube 2 for rotation, and a rotating gear 202 is sleeved inside the rotating rod 201; the connecting assembly 4 for connection includes a rotating ring 401 and a penetrating rod 402, the penetrating rod 402 is fixedly connected to a gear ring 403 on one side close to the center tube 1, and a nut 404 is rotatably connected to the outer wall of the penetrating rod 402 close to the connecting tube 3 through a thread, the inner wall of the rotating ring 401 is meshed with the outer wall of the gear ring 403, and the inner wall of the rotating ring 401 is processed with gear teeth meshed with the outer wall of the gear ring 403.

[0027] like Figure 3 , Figure 5 As shown, both ends of the sliding moving rod 5 are slidably connected with the inner wall of the central tube 1 through a pushing plug 501, and the side wall of the moving rod 5 is surrounded by a plurality of sliding grooves 502, and a toothed belt 503 is arranged inside the sliding groove 502, and the rotating gear 202 is meshed with the toothed belt 503 inside a sliding groove 502, and the pushing plug 501 is tilted toward the center on the side away from the moving rod 5, and the pushing plug 501 is respectively slidably connected with the inner walls of the central tube 1 and the connecting tube 3, and the tilting of the sliding groove 502 is limited by the rotating gear 202, thereby realizing the restriction of the moving rod 5. At the same time, since the outer wall of the moving rod 5 is provided with a plurality of sliding grooves 502 and toothed belts 503, when a single sliding groove 502 or toothed belt 503 is worn, the connection between the rotating gear 202 and the toothed belt 503 can be released, and then the moving rod 5 can be rotated, and different sliding grooves 502 can be replaced to correspond to the rotating gear 202, so that the new toothed belt 503 is reconnected with the rotating gear 202 without replacing the moving rod 5.

[0028] like Figure 2 , Figure 4 As shown, the outer walls at both ends of the central tube 1 are surrounded by connecting flanges 101, and the outer wall of the connecting tube 3 is provided with a mounting flange 301 at one end close to the central tube 1. The inner side of the rotating tube 2 close to the central tube 1 is communicated with the inner part of the central tube 1, and the top of the end of the connecting tube 3 away from the central tube 1 is penetrated by a conveying pipe 302. The connecting tube 3 moves toward the central tube 1 to achieve a fitting connection with the central tube 1. At the same time, since multiple penetrating rods 402 rotate at the same time, the connection can be effectively maintained uniform, and when disassembly is required, the rotating ring 401 can be rotated in the reverse direction to drive the penetrating rods 402 to rotate in the reverse direction, thereby facilitating the release of the connection, replacement and rotation adjustment.

[0029] like Figure 1 , Figure 4 As shown, the interior of the rotating ring 401 is rotatably connected to the outer wall of the connecting flange 101 through a bearing, and the inner wall of the rotating ring 401 is sleeved and fitted with the mounting flange 301, the gear ring 403 is rotatably connected to one side of the connecting flange 101, the nut 404 is fixedly connected to the outer wall of the mounting flange 301, the penetration rod 402 penetrates the interior of the connecting flange 101 and the mounting flange 301 respectively, and the interior of the connecting flange 101 and the mounting flange 301 are both provided with a through hole corresponding to the penetration rod 402, the connecting tube 3 and one end of the central tube 1 are made to correspond to each other, so that the penetration rod 402 passes through the interior of the mounting flange 301 and is connected to the nut 404, and then the rotating ring 401 can be rotated, so that the rotating ring 401 drives the gear ring 403 to rotate and then the penetration rod 402 rotates, and at the same time, because the nut 404 is fixed to the mounting flange 301, the penetration rod 402 and the nut 404 can be evenly connected to each other, thereby driving the connecting tube 3 to move toward the central tube 1.

[0030] When in use, the delivery pipe 302 can be conveniently connected to the corresponding hydraulic pump, and then the corresponding hydraulic pump can deliver hydraulic oil to the inside of the connecting tube 3 through the delivery pipe 302, so that the push plug 501 can be moved, thereby driving the moving rod 5 to move so that the toothed belt 503 is driven, so that the rotating gear 202 rotates, and then the rotating rod 201 rotates, thereby realizing the conversion of reciprocating movement into rotary movement. Since one side of the rotating gear 202 is located in the inside of the slide groove 502 and meshes with the toothed belt 503 during use, the slide groove 502 restricts the rotating gear 202, thereby limiting the rotation of the rotating gear 202. The rotating gear 202 is controlled to tilt and disengage from the toothed belt 503, thereby avoiding deformation. At the same time, the sliding groove 502 can be limited to tilt by the rotating gear 202, thereby realizing the restriction of the moving rod 5. At the same time, since the outer wall of the moving rod 5 is provided with multiple sliding grooves 502 and toothed belts 503, when a single sliding groove 502 or toothed belt 503 is worn, the connection between the rotating gear 202 and the toothed belt 503 can be released, and then the moving rod 5 can be rotated to replace a different sliding groove 502 and the rotating gear 202 to correspond to each other, and then the new toothed belt 503 can be reconnected to the rotating gear 202 without replacing the moving rod 5.

[0031] During installation, the connecting tube 3 can be made to correspond to one end of the central tube 1, so that the through rod 402 passes through the interior of the mounting flange 301 and is connected to the nut 404, and then the rotating ring 401 can be rotated, so that the rotating ring 401 drives the gear ring 403 to rotate and then the through rod 402 rotates. At the same time, since the nut 404 and the mounting flange 301 are fixed to each other, the through rod 402 and the nut 404 can be evenly connected to each other, thereby driving the connecting tube 3 to move toward the central tube 1, thereby achieving a fitting connection with the central tube 1. At the same time, since multiple through rods 402 rotate at the same time, the connection can be effectively maintained uniformly, and when disassembly is required, the rotating ring 401 can be rotated in the reverse direction to drive the through rods 402 to rotate in a unified reverse direction, thereby facilitating the release of the connection, replacement and rotation adjustment.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
