Description

Technical Field

[0001] The utility model relates to the technical field of can cover opening devices, in particular to a can cover opening device. Background Art

[0002] The can lid opening device is a device for opening the can lid; the current Chinese patent announcement number: CN213923987U discloses a modular lid opener, which is mainly composed of a handle shaft, a retaining frame, a gear part, a special-shaped rack part, a special-row rack part, and a modular retaining edge group with different curvature radii; the handle is connected to the gear part, the gear is assembled in the groove position of the retaining frame, the retaining frame is matched with the handle hole axis, the gear is matched with the handle shaft hole axis, the special-shaped rack and the special-shaped rack are assembled on the retaining frame, and form a gear-rack kinematic pair with the gear; through the above scheme, the handle is turned to form a gear-rack kinematic pair with the handle The handle shaft integrated with the hand rotates at the same time, and the torque is transmitted to the gear through the pin. The gear drives the special-shaped rack and the special-shaped rack to move in the opposite direction. The special-shaped rack is driven to move by the rotating gear, so that the rib on the special-shaped rack clamps the bottle cap, and the rotation generates a friction torque to open the bottle cap. However, in the above-mentioned modular opener structure, since the bottle cap is clamped by only two oppositely arranged ribs, there is a disadvantage of poor reliability of the ribs clamping the bottle cap, that is, when the modular bottle opener opens the bottle cap, the ribs and the bottle cap are prone to relative sliding due to unreliable clamping, which leads to the disadvantage of difficulty in opening the bottle cap. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a can lid opening device, which can make the can lid opening device more easily open the can lid, that is, can improve the reliability of opening the can lid.

[0004] The utility model provides a can lid opening device, comprising an operating handle and two clamping units; the two clamping units are distributed up and down and are vertical to each other in space; each clamping unit comprises a support frame and two clamping blocks, the two clamping blocks in each clamping unit are respectively located at the outer sides of the two ends of the support frame in the corresponding clamping unit, the two clamping blocks in each clamping unit are horizontally slidably connected with the support frame in the corresponding clamping unit, the support frames in the two clamping units are distributed up and down and are vertical to each other in space, and the support frames in the two clamping units are fixedly connected; the lower end of the operating handle is vertically penetrated in the support frames in the two clamping units and is rotatably connected with the support frames, and the two clamping blocks in each clamping unit are transmission-connected to the lower end of the operating handle through a transmission mechanism; when the operating handle is rotated, the operating handle is used to drive the two clamping blocks in each clamping unit to approach or move away from each other.

[0005] With the arrangement of two clamping units in the present utility model, when the two clamping blocks in each clamping unit approach each other, the two clamping blocks in each clamping unit can clamp on the outer wall of the can lid, so that the can lid opening device can be reliably clamped with the can lid, avoiding slippage between the can lid opening device and the can lid, and thus making it easier for the can lid opening device to open the can lid, that is, improving the reliability of opening the can lid.

[0006] In a possible implementation manner, sliding grooves are provided on the inner walls of both sides at the lower end of each support frame. Each sliding groove runs through the support frame along the length direction of the support frame. On both sides of each clamping block, sliding strips extending towards one side of the corresponding support frame are provided. The sliding strips located on both sides of each clamping block are slidably connected in the two sliding grooves on the corresponding support frame. After adopting this structure, under the cooperative action of the sliding strips and the sliding grooves, each clamping block can be reliably horizontally slidably connected to the support frame in the corresponding clamping unit, that is, when the operating handle drives the two clamping blocks in each clamping unit to approach or separate from each other, each clamping block can be reliably horizontally slid relative to the support frame in the corresponding clamping unit.

[0007] In a possible implementation manner, each transmission mechanism includes a gear. Each gear is arranged in the middle of the inner top of the corresponding support frame. The lower end of the operating handle is coaxially inserted through the two gears and fixed to the gears. The gear located above is vertically limited between the two support frames. On the inner wall of the sliding strip on one side of each clamping block, a rack portion is provided. The two rack portions in the same clamping unit are respectively located on both sides of the gear at the corresponding position. Each rack portion meshes with the gear at the corresponding position. After adopting this structure, when the operating handle is rotated towards one side, under the cooperative action of the gear and the rack portion, the clamping blocks in each clamping unit can approach each other. When the operating handle is rotated towards the other side, under the cooperative action of the gear and the rack portion, the clamping blocks in each clamping unit can separate from each other, that is, by controlling the rotation direction of the operating handle, it is convenient to control the clamping blocks in each clamping unit to approach or separate from each other.

[0008] In a possible implementation manner, the lower end surfaces of all the clamping blocks are on the same horizontal plane. After adopting this structure, when the clamping blocks in each clamping unit clamp the can lid, all the clamping blocks can be reliably clamped on the outer side wall of the can lid, avoiding the situation of unbalanced clamping of the can lid.

[0009] In a possible implementation, an anti-slip rubber pad is fixedly attached to the inner end face of each clamping block; after fixedly attaching an anti-slip rubber block to the inner end face of each clamping block, when the clamping block is clamped to the outer wall of the can lid, the friction between the clamping block and the can lid can be increased, that is, the situation of slipping between the clamping block and the can lid can be avoided, so that the clamping block can reliably clamp the can lid.

[0018] SeeFigures 1-4 As shown, the embodiment of the present application discloses a can lid opening device, comprising an operating handle 1 and two clamping units; the two clamping units are distributed up and down and are perpendicular to each other in space; each clamping unit comprises a support frame 2 and two clamping blocks 3, the two clamping blocks 3 in each clamping unit are respectively located on the outsides of the two ends of the support frame 2 in the corresponding clamping unit, the two clamping blocks 3 in each clamping unit are horizontally slidably connected to the support frame 2 in the corresponding clamping unit, the support frames 2 in the two clamping units are distributed up and down and are perpendicular to each other in space, and the support frames 2 in the two clamping units are fixedly connected; the lower end of the operating handle 1 is vertically penetrated in the support frames 2 in the two clamping units and is rotatably connected to the support frames 2, and the two clamping blocks 3 in each clamping unit are transmission connected to the lower end of the operating handle 1 through a transmission mechanism; when the operating handle 1 is rotated, the operating handle 1 is used to drive the two clamping blocks 3 in each clamping unit to move closer to or away from each other.

[0019] When using the utility model, firstly place the utility model above the can lid, then rotate the operating handle to one side to control the two clamping blocks in each clamping unit to approach each other until all the clamping blocks are clamped on the outer wall of the can lid, and then continue to rotate the operating handle to one side. At this time, when the clamping blocks clamp the can lid, the operating handle exerts a torque on the can lid through the clamping blocks, so that the can lid can be rotated to open; after the can lid is rotated to open, rotate the operating handle to the other side to make the two clamping blocks in each clamping unit move away from each other and release the clamping state of the can lid.

[0020] Slide grooves 21 are provided on the inner walls on both sides of the lower end of each support frame 2, and each slide groove 21 penetrates the support frame 2 along the length direction of the support frame 2. Sliding bars 31 extending toward the corresponding support frame 2 are provided on both sides of each clamping block 3, and the sliding bars 31 located on both sides of each clamping block 3 are slidably connected in the two slide grooves 21 on the corresponding support frame 2; by adopting this structure, under the cooperation of the sliding bars and the slide grooves, each clamping block can be reliably connected to the support frame in the corresponding clamping unit for horizontal sliding, that is, when the operating handle drives the two clamping blocks in each clamping unit to move closer to or away from each other, each clamping block can reliably slide horizontally relative to the support frame in the corresponding clamping unit.

[0021] Each transmission mechanism includes a gear 4, and each gear 4 is arranged in the middle of the inner top of the corresponding support frame 2. The lower end of the operating handle 1 coaxially penetrates through the two gears 4 and is fixed to the gears 4. The gear 4 located above is vertically limited between the two support frames 2; on the inner wall of the sliding strip 31 on one side of each clamping block 3, a rack portion 32 is provided.

When the operating handle is rotated to the other side, under the cooperation of the gear and the rack portion, the clamping blocks in each clamping unit can be made to move away from each other, that is, by controlling the rotation direction of the operating handle, it is convenient to control the clamping blocks in each clamping unit to approach or move away from each other.

[0022] The lower end surfaces of all the clamping blocks 3 are on the same horizontal plane; after adopting this structure, when the clamping blocks in each clamping unit clamp the can lid, all the clamping blocks can be reliably clamped on the outer side wall of the can lid to avoid the situation of unbalanced clamping of the can lid.
