Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically a bucket lid with a quick-locking structure. Background Technology

[0002] As a sealing and protective component for barrel-shaped containers in the chemical, food, and pharmaceutical industries, existing technologies mostly adopt structures such as threads, snaps, and flip-tops to achieve leak-proof, anti-theft, and dust-proof functions. However, they also face problems such as difficulty in balancing sealing reliability and ease of opening, and low efficiency due to reliance on manual installation in some scenarios.

[0003] A search revealed existing technology (application number: CN202311711284.0), which describes "an easy-to-operate ton container lid locking device, comprising two arc-shaped fixing frames arranged opposite each other, with several limiting grooves opened on the inner ring wall of the arc-shaped fixing frames; a locking mechanism is connected to the arc-shaped fixing frames, a connecting mechanism is provided on the locking mechanism, and a fixing mechanism is connected to the locking mechanism; it requires manual rotation, saving time and effort, and allows the lid to be locked, improving safety; it is fixed by pulling a horizontal lever, which is simple to operate, conforms to the force application posture, and is easy to operate."

[0004] This utility model abandons the existing technology that relies on horizontal operation of the pull rod and adopts a single knob integrated drive structure. It achieves initial positioning through the precise cooperation of the tooth block and tooth groove. The arc-shaped guide groove of the guide plate converts the rotational action into the radial movement of the abutment block. However, it relies on the horizontal pull rod to achieve locking, which requires the cooperation of both hands or switching of the force direction. The operation is scattered, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bucket lid with a quick-locking structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bucket lid with a quick-locking structure, comprising: a chamber, including a box, and an abutment groove is provided on the upper part of the inner side of the box; a lid, arranged on the top of the chamber, including an outer shell, and multiple sets of tooth grooves are provided on the top of the outer shell; a locking structure, arranged inside the lid, including a knob, and four sets of tooth blocks are provided at the bottom of the knob, and the tooth blocks abut against the tooth grooves.

[0030] Example 1:

[0031] like Figures 1 to 3As shown, this embodiment provides a bucket lid with a quick-locking structure, comprising: a chamber 1, including a housing 101, and an abutment groove 102 provided on the upper inner side of the housing 101; a lid 2, arranged on the top of the chamber 1, including an outer shell 201, and multiple sets of toothed grooves 202 provided on the top of the outer shell 201; and a locking structure 3, arranged inside the lid 2, including a knob 301, and four sets of toothed blocks 302 provided at the bottom of the knob 301, and the toothed blocks 302 abutting against the toothed grooves 202.

[0032] In this embodiment, the hatch cover structure and the locking structure constitute a bucket lid with a quick-locking structure as described in this application.

[0033] It should also be noted that the bucket lid in this application can be a bucket lid with a quick-locking structure, a conventional bucket lid, etc. Figure 1 In this embodiment, a bucket lid with a quick-locking structure is used as an example for description. Of course, other types of bucket lids can also adopt a similar structure, which will not be described in detail below.

[0034] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the quick-locking mechanism of the bucket lid; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the quick-locking structure of the bucket lid can also include, compared to... Figure 1 More or fewer parts.

[0035] Furthermore, in this embodiment, the knob 301 forms a preliminary position with the toothed groove 202 of the outer casing 201 through the toothed block 302. Rotating the knob 301 can drive the subsequent components to move, realizing the preliminary linkage positioning of the locking structure 3 and the hatch 2, providing a basis for rapid locking.

[0036] Specifically, the outer shell 201 has a through hole in the center, and the outer shell 201 abuts against the box 101.

[0037] In this embodiment, the through hole provides an installation channel for the knob 301, and the contact between the outer shell 201 and the box 101 forms a sealed base, ensuring the assembly feasibility of the knob 301, while improving the fit between the compartment 1 and the cover 2.

[0038] Specifically, the hatch 2 includes: a second outer shell 203, which is arranged at the bottom of the first outer shell 201 and fixedly connected to the first outer shell 201, and has sliding grooves 204 on both sides; a rotating shaft 205, which is arranged at the top center of the second outer shell 203 and fixedly connected to the second outer shell 203; and two sets of T-shaped sliders 206, which are arranged at the top of the second outer shell 203.

[0039] In a preferred embodiment, the outer shell 203 carries the internal components, the slide groove 204 and the T-shaped slider 206 together provide guidance for the abutment block 305, the rotating shaft 205 provides the rotation center for the guide plate 303, and constructs the internal mounting frame of the hatch 2 to provide stable guidance for the movement of the locking structure 3.

[0040] It should be noted that a sealing gasket is provided between the outer shell 203 and the box 101.

[0041] Example 2:

[0042] Based on Example 1, in order to further improve stability, a locking structure 3 is arranged inside the hatch 2;

[0043] Specifically, the locking structure 3 includes: a guide plate 303 having two sets of arc-shaped guide grooves.

[0044] In this embodiment, the arc-shaped guide groove cooperates with the guide rod 304 to convert the rotational motion of the guide plate 303 into the radial linear motion of the guide rod 304, thereby realizing the conversion of motion form and providing a power transmission path for the extension and retraction of the abutment block 305.

[0045] Specifically, the locking structure 3 further includes: two sets of guide rods 304, arranged in the arc-shaped guide groove of the guide plate 303 and slidably connected to the arc-shaped guide groove of the guide plate 303; two sets of abutment blocks 305, fixedly connected to the guide rods 304, with a T-shaped sliding groove at the bottom, slidably connected to the T-shaped slider 206 and the sliding groove 204, and also abutting against the abutment groove 102.

[0046] With this configuration, when the guide plate 303 rotates, the arc-shaped guide groove pushes the guide rod 304 to move radially. The guide rod 304 drives the abutment block 305 to slide along the slide groove 204 and the T-shaped slider 206, so that the abutment block 305 is inserted into or released from the abutment groove 102 of the cabin 1. Through mechanical linkage, the hatch cover 2 and the cabin 1 are quickly locked and unlocked. The cooperation between the abutment block 305 and the abutment groove 102 ensures the reliability of the locking.

[0047] Specifically, the knob 301 passes through the through hole opened in the outer casing 201 and is fixedly connected to the guide plate 303.

[0048] The external knob 301 rotates synchronously with the internal guide plate 303 through a fixed structure, thereby transmitting power from the operating end to the execution end. This simplifies the operation and allows users to complete locking and unlocking actions with a single knob, improving ease of operation.

[0049] Specifically, the guide plate 303 is arranged on the top of the rotating shaft 205, and a limiting groove 306 is opened in the center of the guide plate 303. It is rotatably connected to the rotating shaft 205 and slidably connected to the rotating shaft 205 through the limiting groove 306.

[0050] In this embodiment, the rotating shaft 205 provides a fixed rotation center for the guide plate 303, and the limiting groove 306 restricts the radial displacement of the guide plate 303 while allowing the guide plate 303 to slide slightly along the axial direction of the rotating shaft 205. This ensures stable contact between the tooth block 302 and the tooth groove 202, improves the stability of the movement of the guide plate 303, avoids jamming during the locking process, and ensures the reliability of the engagement between the tooth block 302 and the tooth groove 202.

[0051] In actual use, first place the box 101 on the working ground, then fill the box 101 with water. After filling, place the outer shell 201 on top of the box 101 and the outer shell 203 into the box 101. Then apply an upward pulling force to the knob 301. The knob 301 drives the guide plate 303 and the toothed block 302 to rise, so that the toothed block 302 leaves the toothed groove 202, releasing the restriction on the hatch 2. Then rotate the knob 301 to drive the guide plate 303 to rotate, so that the guide rod 304 slides in the arc-shaped guide groove opened in the guide plate 303, driving the abutment block 305 to slide outward in the T-shaped slider 206. The abutment block 305 slides out of the slide groove 204 and abuts against the abutment groove 102. Then release the pulling force on the knob 301. The knob 301 drives the guide plate 303 and the toothed block 302 to fall naturally, so that the toothed block 302 is engaged in the toothed groove 202 for locking.

[0052] This design seamlessly integrates ease of operation with structural reliability. The internal mechanical linkage can be driven by a single knob, enabling quick locking and unlocking of the hatch cover and body without the need for complex tools or multiple steps. The knob and toothed groove work together to form initial positioning, and the rotational motion is efficiently converted into the radial movement of the abutment block via the guide plate. This significantly reduces opening and closing time and improves efficiency. At the same time, the guiding and limiting structure ensures stable and jam-free transmission. The tight fit between the abutment block and the abutment groove creates a secure locking effect, preventing loosening during use and providing reliable protection for the sealing of the tank and safe use.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
