Description

Technical Field

[0001] This utility model relates to the field of ton container top cover technology, specifically a ton container top cover locking device. Background Technology

[0002] 1000L IBCs are essential tools for modern warehousing and transporting liquid products. Named for their typical 1000L capacity, capable of holding approximately one ton of goods, they are also known as 1000L containers. Using IBCs significantly reduces production, storage, transportation, and operational costs, saving manpower and resources. The IBC top cover, or sealing component, is a crucial part of the IBC structure for sealing and material handling. Its tight fit with the container body prevents leakage and blocks external dust, impurities, and moisture, ensuring the purity and safety of the stored liquid. This is especially vital for storing liquids such as chemical raw materials and food / beverage products.

[0003] In existing technologies, locking the top cover of a ton container typically requires auxiliary tools. However, these tools are usually only suitable for a single size of top cover and cannot be adjusted to meet specific needs, making them inconvenient and limiting their use. Therefore, we propose a ton container top cover locking device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a locking device for the top cover of a ton container, which solves the problem that locking the top cover of a ton container usually requires the use of auxiliary tools. However, these tools are typically only suitable for top covers of a single size and cannot be adjusted according to actual needs, making them unsuitable for different top covers and thus limiting their use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A locking device for a ton container lid includes a fixed frame, an adjusting frame symmetrically slidably connected inside the fixed frame, a first double-acting screw rotatably connected inside the fixed frame, the adjusting frame being threadedly connected to the first double-acting screw, a connecting seat fixedly connected to one side of the adjusting frame, a clamping plate on one side of the connecting seat, and an anti-slip pad on one side of the clamping plate, a fixed seat symmetrically fixedly connected to the outer side of the fixed frame, a connecting frame fixedly connected to one side of the fixed seat, a push block slidably connected inside the connecting frame, an insert rod fixedly connected to one side of the push block, an adjusting block slidably connected to the inner wall of the fixed seat, a handle fixedly connected to one side of the adjusting block, slots equidistantly provided inside the handle for use with the insert rod, and an anti-slip sleeve on the outer side of the handle.

[0007] In a preferred embodiment, a worm gear is fixedly connected to the outer side of the first bidirectional lead screw, a fixing block is fixedly connected to the inner wall of the fixing frame, and a worm gear that cooperates with the worm gear is rotatably connected between the fixing block and the fixing frame.

[0008] The technical effect of adopting the above-mentioned further solution is that the worm gear drives the worm wheel to rotate, thereby driving the first bidirectional lead screw to rotate, and the rotation of the first bidirectional lead screw drives the two sets of adjusting frames to slide along the inner wall of the fixed frame.

[0009] In a preferred embodiment, a first knob is fixedly connected to one end of the worm gear, and anti-slip textures are provided at equal intervals on the outer side of the first knob. The adjusting frame is in contact with the inner wall of the fixed frame.

[0010] The technical effect of adopting the above-mentioned further solution is that the anti-slip texture can increase the friction, thereby preventing slippage when turning the first knob, making it easier to turn the first knob. The first knob drives the worm gear to rotate, and the movement of the adjusting frame can be limited by the inner wall of the fixed frame, so that the adjusting frame slides along the inner wall of the fixed frame and prevents deviation.

[0011] In a preferred embodiment, the connecting seat has a slider symmetrically slidably connected inside, a connecting block is fixedly connected to one side of the slider, a locking block is fixedly connected to one side of the connecting block at equal intervals, an installation block is fixedly connected to one side of the clamping plate, and the installation block has symmetrically opened locking grooves inside for use with the locking block.

[0012] The technical effect of adopting the above-mentioned further solution is that the connecting block is moved by the slider, the connecting block moves the locking block, and the locking block moves into the locking groove to lock the position of the mounting block, which facilitates the quick installation and fixation of the clamping plate.

[0013] In a preferred embodiment, the inner wall of the connecting seat is symmetrically fixedly connected with a limiting rod, and the connecting block is slidably connected to the limiting rod.

[0014] The technical effect of adopting the above-mentioned further solution is that the movement of the connecting block can be limited by setting the limiting rod, so that the connecting block slides along the limiting rod and prevents deviation.

[0015] In a preferred embodiment, a second bidirectional lead screw is rotatably connected inside the connecting seat, the slider is threadedly connected to the second bidirectional lead screw, a second knob is fixedly connected to one end of the second bidirectional lead screw, and anti-slip textures are provided at equal intervals on the outer side of the second knob.

[0016] The technical effect of adopting the above-mentioned further solution is that the anti-slip texture can increase the friction, thereby preventing slippage when rotating the second knob, making it easier to rotate the second knob. The second knob drives the second bidirectional lead screw to rotate, and the rotation of the second bidirectional lead screw drives the two sets of sliders to slide along the inner wall of the connecting seat.

[0017] In a preferred embodiment, a fixing rod is fixedly connected to the inner wall of the connecting frame, the push block is slidably connected to the fixing rod, and a return spring is sleeved on the outer side of the fixing rod and on one side of the push block.

[0018] The technical effect of adopting the above-mentioned further solution is that the reset spring can drive the push block to move and reset, and the fixed rod can limit the movement of the push block, so that the push block slides along the fixed rod to prevent deviation.

[0019] This utility model provides a locking device for the top cover of a ton container. Compared with the prior art, it has the following advantages:

[0020] 1. This ton container top cover locking device, through the configuration of a first bidirectional screw rod, adjusting brackets, connecting seats, clamping plates, fixing seats, connecting frames, push blocks, insert rods, adjusting blocks, handles, and slots, achieves the function of assisting in locking the ton container top cover. It can be used with top covers of different sizes, thus having a wider range of applications. Furthermore, the handle length can be adjusted according to the user's needs for better performance. When locking the ton container top cover, move the two sets of clamping plates to both sides of the top cover, and rotate the first knob. The first knob drives the worm gear to rotate, thereby driving the first bidirectional screw rod to rotate. The rotation of the first bidirectional screw rod causes the two sets of adjusting brackets to slide along the inner wall of the fixing frame. The adjusting brackets drive the clamping plates to move through the connecting seats. The two sets of clamping plates clamp and fix the ton container top cover. The anti-slip pads enhance the fixing effect. Rotating the handle rotates the ton container top cover, thus tightening it to the ton container. The operation is convenient.

[0021] 2. This ton container top cover locking device, through the configuration of a second bidirectional screw rod, slider, connecting block, limit rod, locking block, mounting block, and locking groove, enables quick assembly and disassembly of the clamping plate. This facilitates rapid replacement of the clamping plate. When a different type of clamping plate needs to be used, rotating the second knob causes the second bidirectional screw rod to rotate. The rotation of the second bidirectional screw rod causes the slider to slide along the inner wall of the connecting seat. The slider causes the connecting block to slide along the limit rod. The connecting block then causes the locking block to move and disengage from the locking groove, thereby releasing the locking state of the mounting block and allowing the clamping plate to be removed for replacement. The operation is convenient. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1 to 8 This utility model provides a technical solution:

[0037] A locking device for a ton container lid includes a fixed frame 1. An adjusting frame 12 is symmetrically and slidably connected inside the fixed frame 1. A first bidirectional lead screw 14 is rotatably connected inside the fixed frame 1. The adjusting frame 12 is threadedly connected to the first bidirectional lead screw 14. A connecting seat 3 is fixedly connected to one side of the adjusting frame 12. A clamping plate 31 is provided on one side of the connecting seat 3. An anti-slip pad is provided on one side of the clamping plate 31. A fixed seat 2 is symmetrically and fixedly connected to the outside of the fixed frame 1. A connecting frame 4 is fixedly connected to one side of the fixed seat 2. A push block 42 is slidably connected inside the connecting frame 4. An insertion rod 41 is fixedly connected to one side of the push block 42. An adjusting block 24 is slidably connected to the inner wall of the fixed seat 2. A handle 22 is fixedly connected to one side of the adjusting block 24. The handle 22 has slots 23 equidistantly opened inside for use with the insertion rod 41. An anti-slip sleeve 21 is provided on the outside of the handle 22.

[0038] In this scheme, the rotation of the first bidirectional lead screw 14 drives the two sets of adjusting frames 12 to slide along the inner wall of the fixed frame 1. The adjusting frame 12 drives the clamping plate 31 to move through the connecting seat 3. The two sets of clamping plates 31 can clamp and fix the top cover of the ton container. The anti-slip pad can enhance the fixing effect. It can be used with top covers of different sizes, making it more applicable. Turning the handle 22 can drive the top cover of the ton container to rotate, thereby tightening it between the top cover and the ton container. The operation is convenient. The movement of the adjusting block 24 drives the handle 22 to move, thereby adjusting the length of the handle 22 during use. The anti-slip sleeve 21 can play an anti-slip role and facilitate the rotation of the handle 22.

[0039] like Figure 1 and Figure 2 As shown: In this scheme, a worm gear 13 is fixedly connected to the outer side of the first bidirectional lead screw 14, a fixing block 15 is fixedly connected to the inner wall of the fixing frame 1, and a worm 16 that works with the worm gear 13 is rotatably connected between the fixing block 15 and the fixing frame 1; a first knob 11 is fixedly connected to one end of the worm 16, and anti-slip textures are provided at equal intervals on the outer side of the first knob 11; the adjusting frame 12 is in contact with the inner wall of the fixing frame 1.

[0040] In this solution, when locking the top cover of the ton container, the two sets of clamping plates 31 are moved to both sides of the top cover. The anti-slip texture increases friction, preventing slippage when turning the first knob 11 and facilitating its rotation. Turning the first knob 11 causes the worm gear 16 to rotate, which in turn drives the first double-acting screw 14. The rotation of the first double-acting screw 14 causes the two sets of adjusting brackets 12 to slide along the inner wall of the fixed frame 1. The adjusting brackets 12 move the clamping plates 31 through the connecting seat 3. The two sets of clamping plates 31 clamp and fix the top cover of the ton container. The anti-slip pads enhance the fixing effect. Turning the handle 22 rotates the top cover of the ton container, tightening it between the lid and the container. The operation is convenient.

[0041] like Figures 3 to 5 As shown: In this scheme, the connecting seat 3 has a slider 34 symmetrically slidably connected inside, a connecting block 36 is fixedly connected to one side of the slider 34, a locking block 37 is fixedly connected to one side of the connecting block 36 at equal intervals, and an mounting block 39 is fixedly connected to one side of the clamping plate 31. The mounting block 39 has locking grooves 38 symmetrically opened inside to cooperate with the locking block 37. The inner wall of the connecting seat 3 is symmetrically fixedly connected to a limit rod 32, and the connecting block 36 is slidably connected to the limit rod 32. The connecting seat 3 has a second bidirectional lead screw 35 rotatably connected inside, the slider 34 is threadedly connected to the second bidirectional lead screw 35, and a second knob 33 is fixedly connected to one end of the second bidirectional lead screw 35. The outer side of the second knob 33 is provided with anti-slip texture at equal intervals.

[0042] In this solution, when it is necessary to replace the clamping plate 31 with a different type, the second knob 33 is rotated. The anti-slip texture increases the friction, preventing slippage when rotating the second knob 33. The second knob 33 drives the second bidirectional lead screw 35 to rotate. The rotation of the second bidirectional lead screw 35 drives the slider 34 to slide along the inner wall of the connecting seat 3. The slider 34 drives the connecting block 36 to slide along the limiting rod 32. The connecting block 36 drives the locking block 37 to move and disengage from the locking groove 38, thereby releasing the locking state of the mounting block 39, and the clamping plate 31 can be removed for replacement. The operation is convenient.

[0043] like Figure 8 As shown: In this scheme, a fixing rod 44 is fixedly connected to the inner wall of the connecting frame 4, the push block 42 is slidably connected to the fixing rod 44, and a return spring 43 is sleeved on the outer side of the fixing rod 44 and on one side of the push block 42.

[0044] In this solution, when the length of the handle 22 needs to be adjusted, the push block 42 is pushed, and the return spring 43 is compressed. The movement of the push block 42 can be limited by the setting of the fixing rod 44, so that the push block 42 slides along the fixing rod 44 to prevent displacement. The push block 42 drives the insertion rod 41 to move out of the slot 23, so the handle 22 can be pulled to move, thereby adjusting its length during use. After the adjustment is completed, the push block 42 is released, and the return spring 43 will drive the push block 42 to move and reset due to the elastic force. The push block 42 drives the insertion rod 41 to move into the corresponding slot 23, thereby locking the position of the handle 22, which is convenient to operate.

[0045] Working principle:

[0046] In use, when locking the top cover of the ton container, move the two sets of clamping plates 31 to both sides of the top cover, and turn the first knob 11. The first knob 11 drives the worm wheel 13 to rotate through the worm gear 16, thereby driving the first double-acting screw 14 to rotate. The rotation of the first double-acting screw 14 causes the two sets of adjusting brackets 12 to slide along the inner wall of the fixed bracket 1. The adjusting brackets 12 drive the clamping plates 31 to move through the connecting seat 3. The two sets of clamping plates 31 can clamp and fix the top cover of the ton container. The anti-slip pad can enhance the fixing effect. Turning the handle 22 can drive the top cover of the ton container to rotate, thereby tightening it between the lid and the ton container. The operation is convenient. When it is necessary to adjust the length of the handle 22 during use, push the push block 42. The return spring 43 is compressed, and the push block 42 drives the insertion rod 41 to move and disengage from the slot. 23. Pull the handle 22 to move it, thereby adjusting its length for use. After adjustment, release the push block 42. The return spring 43 will move the push block 42 to return to its original position due to its elasticity. The push block 42 will move the insertion rod 41 into the corresponding slot 23, thereby locking the position of the handle 22. The operation is convenient. When it is necessary to replace the clamp 31 with a different type, turn the second knob 33. The second knob 33 will drive the second bidirectional screw 35 to rotate. The rotation of the second bidirectional screw 35 will drive the slider 34 to slide along the inner wall of the connecting seat 3. The slider 34 will drive the connecting block 36 to slide along the limit rod 32. The connecting block 36 will drive the locking block 37 to move away from the locking groove 38, thereby releasing the locking state of the mounting block 39, so that the clamp 31 can be removed for replacement. The operation is convenient.
