Description

Technical Field

[0001] This application belongs to the technical field of can lid opening tools, and particularly relates to a can lid opening tool. Background Technology

[0002] Scale inhibitors play a crucial role in slowing down or preventing scale buildup in water production and treatment processes, and are the most widely used agents in the water treatment industry.

[0003] Currently, scale inhibitors sold on the market are generally liquid agents in 200L / drum containers. When adding them, operators need to open the agent container and then pour it into the dosing tank of the fixed dosing system. The agent container has two lids, one outer lid (e.g., an outer lid). Figure 5 (as shown) and an inner cover (as shown) Figure 6 As shown), the outer cover is interference-fitted with the cylinder body and covers the inner cover, while the inner cover is threadedly connected to the cylinder body.

[0004] In related technologies, when opening a medicine container, the outer cover is first pried open with a crowbar, and then the inner cover is struck with a hammer and a stick to make it rotate and open. This is not only time-consuming and laborious, but also poses a safety hazard during the striking process. If the inner cover is damaged, it will affect the subsequent recycling of the empty container. Utility Model Content

[0040] In related technologies, medicine containers suffer from the technical problem of inconvenient opening. This application provides a lid-opening tool that can at least partially solve the technical problem of inconvenient opening of medicine containers.

[0041] This application is described below with reference to the accompanying drawings and specific embodiments:

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lid-opening tool 100 includes a gripping member 110, a lifting assembly 120, a first limiting member 130, and a second limiting assembly 140. Along the length of the gripping member 110, the lifting assembly 120 is mounted on one side of the gripping member 110, and the end of the lifting assembly 120 away from the gripping member 110 has a lifting portion 1211 for lifting the first lid. The first limiting member 130 and the second limiting assembly 140 are both mounted on the gripping member 110, and are arranged opposite to each other along the length of the gripping member 110, serving to abut against the second lid.

[0043] The lid-opening tool 100 can be used to open medicine containers, cream containers, etc. The specific type of container and the specific medium it contains are not limited in this application. (See reference...) Figure 5 As shown, the first cap is interference-fitted onto the barrel body and is installed by pressing. (See reference.) Figure 6 As shown, the second cover is threaded onto the barrel body and is installed by screwing it on. Multiple latches are spaced apart along the circumference of the second cover. When it is a medicine barrel, the outer cover is the first cover, and the inner cover is the second cover.

[0044] The lifting assembly 120 is installed on one side of the grip 110. The lifting assembly 120 has a lifting part 1211. The lifting assembly 120 lifts the first cover upward through the lifting part 1211, so that the first cover is separated from the barrel body, thereby opening the first cover.

[0045] The shape of the raised portion 1211 is diverse and not limited in this application; it can be cylindrical, cuboid, etc. It should be noted that if the lower end face of the first cover is fitted to the barrel body, the thickness of the raised portion 1211 can be designed to be smaller to facilitate its insertion between the first cover and the barrel body. In some embodiments, the lower end face of the first cover is fitted to the barrel body, such as... Figure 3 As shown, the upturned part 1211 is wedge-shaped, with a smaller end away from the gripper 110 and a larger end closer to the gripper 110. With this design, the end away from the gripper 110 is inserted between the first cover and the barrel. As the upturned part 1211 is inserted, the distance between the lower end face of the first cover and the barrel increases under the action of the wedge shape, and the first cover gradually separates from the barrel.

[0046] The first limiting member 130 and the second limiting assembly 140 are disposed opposite each other along the length direction of the gripping member 110, and there is a gap between the first limiting member 130 and the second limiting assembly 140. As described above, please refer to Figure 6 Along the circumference of the second cover, multiple latches are spaced apart, with a gap between adjacent latches and multiple gaps between the latches. When removing the second cover, the first limiting member 130 and the second limiting component 140 are located in two different gaps. Then, the gripping member 110 is turned, which drives the first limiting member 130 and the second limiting component 140 to rotate. The first limiting member 130 and the second limiting component 140 will abut against the latches and push the latches to rotate, thereby driving the second cover to rotate, so that the first cover can be removed from the bucket.

[0047] The opening tool 100 can remove both the first and second lids. When used on a medicine container, it can disassemble both the outer and inner lids separately, facilitating opening and improving efficiency. Furthermore, the tool 100 does not damage the inner or outer lids or the container body during the opening process, extending the container's lifespan and enabling its recycling.

[0048] In some embodiments, the lifting assembly 120 includes a lifting member 121 and a connector 122. The lifting member 121 has a lifting portion 1211 and is slidably connected to the gripper 110 along the length direction of the gripper 110. The connector 122 is connected to either the lifting member 121 or the gripper 110, and under the action of the connector 122, the lifting member 121 can switch between a first state fixed to the gripper 110 and a second state slidable relative to the gripper 110.

[0049] The lifting member 121 can slide along the length of the grip member 110. When the opening tool 100 is not in use, the lifting member 121 can be retracted, thereby reducing the total length of the grip member 110 and the lifting member 121, making it easier to store the opening tool 100. Furthermore, with this design, if the thickness of the lifting part 1211 is too small and could easily scratch the operator, the lifting member 121 can be designed to retract until it does not extend beyond the grip member 110, reducing the risk of the lifting part 1211 scratching the operator when the opening tool 100 is not in use.

[0050] When the lifting member 121 is working, it needs to be fixed in a certain position to prevent it from retracting or extending uncontrollably during the lifting process, which would prevent the first cover from being pushed upwards. Therefore, these embodiments include a connector 122. The connector 122 can be connected to the lifting member 121 or to the gripper 110, and this is not limited in this application. The connector 122 can fix the lifting member 121 to the gripper 110, or it can be left unfixed. When the lifting member 121 is working, it can be fixed to the gripper 110 through the connector 122 to prevent it from retracting or extending uncontrollably. When the length of the lifting member 121 extending out of the holding member 110 needs to be adjusted, the connecting member 122 can be adjusted so that the lifting member 121 is not fixed on the holding member 110, so that the lifting member 121 can slide relative to the holding member 110, thereby adjusting the extension length of the lifting member 121.

[0051] In some embodiments, the gripper 110 has a groove, and the lifting member 121 is slidably connected within the groove. The connector 122 is a screw, which is threaded onto the gripper 110 and passes through the sidewall of the groove. When the screw is tightened against the lifting member 121, the gripper 110 and the lifting member 121 are fixed; when the screw is not tightened against the lifting member 121, the lifting member 121 can slide relative to the gripper 110.

[0052] In some embodiments, the lifting member 121 has a groove, and the gripping member 110 has a guide rail located within the groove. The connecting member 122 is a screw, which is threaded onto the lifting member 121 and passes through the sidewall of the groove. When the screw is pressed against the guide rail of the gripping member 110, the gripping member 110 is fixed to the lifting member 121; when the screw is not pressed against the guide rail of the lifting member 121, the lifting member 121 can slide relative to the gripping member 110.

[0053] In some embodiments, the lifting member 121 further has a first connecting portion 1212 and a second connecting portion 1213. The lifting portion 1211 is connected to one end of the first connecting portion 1212, and the second connecting portion 1213 is connected to one end of the first connecting portion 1212 away from the lifting portion 1211. The second connecting portion 1213 is slidably connected to the gripping member 110, and the connecting member 122 is connected to the second connecting portion 1213 or the gripping member 110.

[0054] The first connecting part 1212 is fixedly connected to the raised part 1211 and also fixedly connected to the second connecting part 1213. The connection can be made by bonding, snap-fitting, threaded connection, or other methods. In some embodiments, the raised part 1211, the first connecting part 1212, and the second connecting part 1213 are integrally formed.

[0055] In some embodiments, the gripper 110 has a first clearance hole 110a and a second clearance hole 110b communicating with the first clearance hole 110a, both extending along the length direction of the gripper 110. A first connecting portion 1212 is disposed within the first clearance hole 110a, and a second connecting portion 1213 is disposed within the second clearance hole 110b. The connector 122 and the first connecting portion 1212 are respectively located on both sides of the second clearance hole 110b, at least a portion of the gripper 110 is located between the connector 122 and the first connecting portion 1212, and the connector 122 is movably connected to the second connecting portion 1213 along the length direction of the second connecting portion 1213.

[0056] Both the first clearance hole 110a and the second clearance hole 110b extend along the length direction of the gripper 110, meaning that both the first clearance hole 110a and the second clearance hole 110b are strip-shaped holes, and the length directions of both the first clearance hole 110a and the second clearance hole 110b are parallel to the length direction of the gripper 110. A first connecting portion 1212 is disposed within the first clearance hole 110a, and the first clearance hole 110a avoids the first connecting portion 1212, allowing the first connecting portion 1212 to move smoothly within the first clearance hole 110a. A second connecting portion 1213 is disposed within the second clearance hole 110b, and the second clearance hole 110b avoids the second connecting portion 1213, allowing the second connecting portion 1213 to move smoothly within the second clearance hole 110b.

[0057] Along the length of the second connecting portion 1213, the connector 122 is movably connected to the second connecting portion 1213. This means that the connector 122 can be connected to different positions along the length of the second connecting portion 1213. The connector 122 can be close to or far from the first connecting portion 1212, so that the distance between the connector 122 and the first connecting portion 1212 can be adjusted. Figure 1 As shown, the second connecting portion 1213 is located below the second clearance hole 110b, the connecting member 122 is located above the second clearance hole 110b, and at least a portion of the gripping member 110 is located between the connecting member 122 and the first connecting portion 1212. With this design, when the distance between the connecting member 122 and the first connecting portion 1212 is small, the connecting member 122 and the first connecting portion 1212 clamp the gripping member 110, thereby fixing the lifting assembly 120 relative to the gripping member 110. When the distance between the connecting member 122 and the first connecting portion 1212 is large, the connecting member 122 and the first connecting portion 1212 do not clamp the gripping member 110, thereby allowing the lifting assembly 120 to slide relative to the gripping member 110.

[0058] The connection method can be varied, including snap-fit, bolt connection, etc., and is not limited in this application.

[0059] In some embodiments, the grip 110 is tubular, the hole in the middle of the grip 110 is the first clearance hole 110a, and the second clearance hole 110b is formed on the peripheral wall of the grip 110.

[0060] In some embodiments, the connector 122 is threadedly connected to the second connecting portion 1213.

[0061] Tightening the connector 122 allows it to move along the length of the second connecting portion 1213, thus moving it closer to or away from the first connecting portion 1212. When the connector 122 is tightened, it moves closer to the first connecting portion 1212, clamping the gripper 110 between them. When the connector 122 is loosened, it moves away from the first connecting portion 1212, releasing the gripper 110.

[0062] In some embodiments, the connector 122 is a nut, and the second connecting portion 1213 has external threads on its peripheral wall.

[0063] In some embodiments, at least one of the first limiting member 130 and the second limiting component 140 is movably connected to the grip member 110 along the length direction of the grip member 110.

[0064] Along the length direction of the grip 110, the first limiting member 130 is movably connected to the grip 110, or the second limiting member 141 is movably connected to the grip 110, or both the first limiting member 130 and the second limiting member 141 are movably connected to the grip 110.

[0065] At least one of the first limiting member 130 and the second limiting member 141 is movably connected to the gripping member 110, so that the distance between the first limiting member 130 and the second limiting member 141 along the length direction of the gripping member 110 can be adjusted, thereby allowing the distance between the first limiting member 130 and the second limiting member 141 to be adaptively adjusted according to the specifications of the second cover, so that the cover opening tool 100 can be used for second covers of different specifications.

[0066] Along the length of the gripper 110, the first limiting member 130 is movably connected to the gripper 110, meaning that the first limiting member 130 can be connected at different positions along the length of the gripper 110. Similarly, along the length of the gripper 110, the second limiting member 141 is movably connected to the gripper 110, meaning that the second limiting member 141 can be connected at different positions along the length of the gripper 110. The movable connection method is diverse, and can be snap-fit, bolt connection, etc., and is not limited in this application.

[0067] In some embodiments, the gripper 110 has a first clearance hole 110a and a second clearance hole 110b and a third clearance hole 110c communicating with the first clearance hole 110a. The second clearance hole 110b and the third clearance hole 110c are disposed opposite to each other, and the first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c all extend along the length direction of the gripper 110. The second limiting component 140 includes a second limiting member 141, a first fastener 142, and a second fastener 143. The second limiting member 141 passes through the first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c. Along the length direction of the second limiting member 141, the first fastener 142 and the second fastener 143 are both movably connected to the second limiting member 141 and are respectively located on both sides of the second clearance hole 110b. At least a portion of the gripper 110 is located between the first fastener 142 and the second fastener 143.

[0068] The first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c all extend along the length direction of the gripper 110, meaning that each of these holes is a strip-shaped hole, and their length directions are parallel to the length direction of the gripper 110. The second limiting member 141 passes through the first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c. The first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c all avoid the second limiting member 141, allowing the second limiting member 141 to move smoothly within the first clearance hole 110a, the second clearance hole 110b, and the third clearance hole 110c along the length direction of the gripper 110. Both the first fastener 142 and the second fastener 143 are movably connected to the second limiting member 141, allowing the first fastener 142 and the second fastener 143 to connect to different positions along the length of the second limiting member 141. The first fastener 142 and the second fastener 143 can move closer to or further away from each other, allowing the spacing between the first fastener 142 and the second fastener 143 to be adjusted. Figure 1 As shown, the first fastener 142 is located above the second clearance hole 110b, and the second fastener 143 is located below the second clearance hole 110b. At least a portion of the gripper 110 is located between the first fastener 142 and the second fastener 143. With this design, when the distance between the first fastener 142 and the second fastener 143 is small, the first fastener 142 and the second fastener 143 clamp the gripper 110, thereby fixing the second limiting component 140 relative to the gripper 110; when the distance between the first fastener 142 and the second fastener 143 is large, the first fastener 142 and the second fastener 143 do not clamp the gripper 110, thereby allowing the second limiting component 140 to move relative to the gripper 110 in the length direction.

[0069] In some embodiments, the grip 110 is tubular, and the hole in the middle of the grip 110 is the first clearance hole 110a. The second clearance hole 110b and the second clearance hole 110c are both formed on the peripheral wall of the grip 110.

[0070] In some embodiments, the first fastener 142 and the second fastener 143 are both threadedly connected to the second limiting member 141.

[0071] Tightening the first fastener 142 allows it to move along the length of the second limiting member 141, thus moving closer to or away from the second fastener 143. Similarly, tightening the second fastener 143 allows it to move along the length of the first limiting member 130, thus moving closer to or away from the first fastener 142. When the first fastener 142 is tightened, it moves closer to the second fastener 143, clamping the gripper 110; when the fastener is loosened, it moves away from the gripper 110, releasing it from the gripper 110. Similarly, when the second fastener 143 is tightened, the first fastener 142 and the second fastener 143 move closer together and clamp the gripper 110; when the second fastener 143 is loosened, the first fastener 142 and the second fastener 143 move further apart and release the gripper 110.

[0072] In some embodiments, the first fastener 142 and the second fastener 143 are both nuts, and the second limiting member 141 has external threads.

[0073] In some embodiments, the gripper 110 has a first side and a second side disposed opposite to each other along the length direction, and the lifting assembly 120, the first limiting member 130 and the second limiting assembly 140 are all mounted on the first side.

[0074] like Figure 1 As shown, the left side of the grip 110 is the first side, and the right side is the second side. The lifting assembly 120, the first limiting member 130, and the second limiting assembly 140 are all installed on the first side, so that when the cover opening tool 100 is used, the operator can hold the second side, which is convenient for the operator to hold.

[0075] In some embodiments, the opening tool 100 further includes an anti-slip sleeve 150 fitted on the second side.

[0076] The anti-slip sleeve 150 can be made of rubber or other materials. Setting the anti-slip sleeve 150 can increase the friction between the palm and the grip 110, making it more comfortable for the operator to hold and easier for the operator to apply force.

[0077] The following describes how to use the lid-opening tool 100:

[0078] When it is necessary to open the first cover, first loosen the connector 122 so that the connector 122 is away from the first connecting part 1212, so that the connector 122 and the first connecting part 1212 no longer clamp the grip 110, so that the lifting assembly 120 can move relative to the grip 110.

[0079] Next, the lifting assembly 120 is moved so that the lifting member 121 of the lifting assembly 120 extends out of the holding member 110;

[0080] Next, tighten the connector 122 so that the connector 122 is close to the first connecting part 1212, thereby clamping the gripper 110 between the connector 122 and the first connecting part 1212, and fixing the lifting assembly 120 relative to the gripper 110.

[0081] Next, the operator holds the anti-slip sleeve 150 of the grip 110, aligns the lifting part 1211 with the first cover, and applies force to the grip 110 so that the first cover is lifted upward and separated from the barrel.

[0082] After the first cover is separated from the barrel, the connector 122 is loosened, so that the connector 122 is moved away from the first connecting part 1212, so that the connector 122 and the first connecting part 1212 no longer clamp the gripper 110, and the lifting assembly 120 can move relative to the gripper 110.

[0083] Next, the lifting assembly 120 is moved so that the lifting member 121 is completely inside the first clearance hole 110a and does not protrude from the first clearance hole 110a;

[0084] Next, tighten the connector 122 so that it is close to the first connecting part 1212, thereby clamping the gripper 110 between the connector 122 and the first connecting part 1212, and fixing the lifting assembly 120 relative to the gripper 110 to prevent the lifting part 1211 from scratching the operator.

[0085] When it is necessary to open the second cover, first loosen the first fastener 142 so that the first fastener 142 is away from the second fastener 143, so that the first fastener 142 and the second fastener 143 no longer clamp the gripper 110, allowing the second limiting component 140 to move relative to the first limiting component 130.

[0086] Next, move the second limiting component 140 and adjust the distance between the first limiting member 130 and the second limiting member 141 so that the distance between the first limiting member 130 and the second limiting member 141 meets the requirements for disassembling the second cover.

[0087] Next, tighten the first fastener 142 so that the first fastener 142 is close to the second fastener 143, thereby clamping the gripper 110 with the first fastener 142 and the second fastener 143, and fixing the second limiting component 140 relative to the first limiting component 130.

[0088] Next, the operator holds the anti-slip sleeve 150 of the grip 110 and places the first limiting member 130 and the second limiting member 141 in two different gaps (a gap is formed between two adjacent buckles). Then, the operator rotates the grip 110, which drives the first limiting member 130 and the second limiting member 141 to rotate. The first limiting member 130 and the second limiting member 141 will abut against the buckle and push the buckle to rotate, thereby driving the second cover to rotate, so that the first cover can be removed from the bucket.
