Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a buckle structure for the lid of a live seafood transport box. Background Technology

[0002] Different live seafood is suited to different aquaculture areas. In order to sell it commercially, live seafood needs to be transported from the aquaculture area to the target location such as the market in transport boxes. During the transportation process, in order to ensure the survival rate of the fish, special live seafood transport boxes are generally used.

[0003] Existing live seafood transport boxes require frequent opening of the lid, so a simple single-clamp spring buckle is generally used between the box body and the lid. However, during the actual transportation and handling of live seafood transport boxes, the spring buckle is often accidentally activated, causing the lid to open unexpectedly, resulting in the live seafood inside the box flowing out of the box and causing additional losses. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-fit ​​structure for the lid of a live seafood transport box, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lid snap-fit ​​structure for a live seafood transport box includes a box body, a lid, and a multi-position snap-fit ​​assembly connecting the box body and the lid.

[0007] The multi-position buckle assembly includes a female buckle fixedly connected to the box body, a male buckle detachably buckled to the female buckle, and an elastic rope passing through both the male buckle and the box cover and knotted to form a closed loop.

[0008] The male fastener includes a fastener body and an arc-shaped handle; the fastener body is symmetrically arranged from left to right and includes a first cylinder, a second cylinder, and a concave arc-shaped connector connecting the first cylinder and the second cylinder; the diameter of the first cylinder is larger than that of the second cylinder; one end of the arc-shaped handle is fixedly connected to both the first cylinder and the arc-shaped connector; the outer walls of the first cylinder, the second cylinder, and the arc-shaped connector on the side away from the arc-shaped handle form a first abutting arc surface; the outer walls of the arc-shaped handle, the arc-shaped connector, and the second cylinder form a second abutting arc surface; the first cylinder has a first through hole for an elastic rope to pass through, and the first through hole is concentric with the first cylinder.

[0009] The female fastener includes a square protrusion fixedly connected to the side wall of the housing and a snap-fit ​​groove disposed on the bottom surface of the square protrusion; the snap-fit ​​groove includes a first groove side wall disposed on the inner side of the snap-fit ​​groove that matches the first abutting arc surface and a second groove side wall disposed on the outer side of the snap-fit ​​groove that matches the second abutting arc surface; the connection between the first groove side wall and the second groove side wall forms an abutting groove that matches the outer wall of the second cylinder, and the second cylinder rotatably abuts against the abutting groove.

[0010] First position: When the arc-shaped handle is subjected to external force, the second cylinder abuts against the abutment groove and rotates until the first abutment arc surface of the male fastener abuts against the side wall of the first groove of the female fastener. At this time, the axis of the elastic rope section along the center of the first through hole to the bottom surface of the box cover is located to the left of the center of the second cylinder and forms an angle of 40°-45° with the line connecting the centers of the first cylinder and the second cylinder. The elastic force provided by the elastic rope causes the male fastener and the female fastener to form a limiting connection.

[0011] Second position: When the arc-shaped handle is subjected to external force, the second cylinder abuts against the abutment groove and rotates until the second abutment arc surface of the male fastener abuts against the side wall of the second groove of the female fastener. At this time, the axis of the elastic rope section along the center of the first through hole to the bottom surface of the box cover is located to the right of the center of the second cylinder and forms an angle of 0°-5° with the line connecting the centers of the first cylinder and the second cylinder. The elastic force provided by the elastic rope causes the male fastener and the female fastener to form a limiting connection.

[0012] Before handling live seafood transport boxes, the multi-position buckle assembly is usually adjusted to the first position. If the curved handle is accidentally touched during transportation or handling, causing it to be pulled outward, the multi-position buckle assembly will adjust to the second position while keeping the lid closed, thus preventing the live seafood inside the box from leaking out and causing loss.

[0013] Preferably, the buckle body and the arc-shaped handle are integrally formed and connected, resulting in a reliable structure.

[0014] Preferably, the second groove sidewall of the snap-fit ​​groove is provided with an arc-shaped protrusion that matches the second abutting arc surface at the connection between the sidewall of the square protrusion away from the sidewall of the box, which facilitates the installation and separation of the multi-position snap-fit ​​assembly;

[0015] During separation, under the action of external force, the arc-shaped handle causes the second abutting arc surface to abut against the arc-shaped protrusion and rotate. At this time, the arc-shaped handle moves away from the side wall of the box until the male fastener and the female fastener are completely separated.

[0016] During installation, the arc-shaped handle, under the action of external force, slides the second cylinder along the arc-shaped protrusion into the side wall of the second groove.

[0017] Preferably, the arc-shaped handle includes an arc-shaped body; the arc-shaped body gradually narrows along the direction away from the buckle, making it easy to grip and operate the handle.

[0018] Preferably, the arc-shaped main body has a third cylinder at the end away from the buckle body, and the line connecting the center of the third cylinder and the first cylinder forms an angle of 115-120° with the line connecting the center of the second cylinder and the first cylinder.

[0019] Compared with the prior art, the lid buckle structure of the live seafood transport box of this application has the following advantages:

[0020] This utility model solves the problem of accidental opening and leakage of live seafood caused by existing single-position spring buckles through the innovative design of multi-position buckle components:

[0021] 1. Dual-level safety protection against accidental touch:

[0022] When the latch is in the first working position (transport locking position), the elastic rope tension forms a 40°–45° angle with the line connecting the center of the cylinder, creating a stable self-locking force. If the curved handle is accidentally pressed outward during handling, the latch will switch to the second working position (safety protection position). At this time, the elastic rope tension changes to a 0°–5° angle, providing secondary locking force while keeping the lid closed. This dual locking mechanism completely avoids the risk of the lid opening due to accidental contact with the single-position latch, ensuring that the box remains sealed even if it is subjected to accidental impact during transportation.

[0023] 2. Targeted unlocking to prevent detachment and loss of control:

[0024] Through the cooperative design of the arc-shaped protrusion of the female fastener and the second abutting arc surface of the male fastener, the arc-shaped handle is controlled to rotate outward along the trajectory of the arc-shaped protrusion when unlocking, which forcibly guides the male fastener to smoothly disengage along a predetermined path, avoiding the sudden popping of parts or instantaneous opening of the lid caused by traditional buckles, thus significantly improving operational safety.

[0025] 3. Optimize operational efficiency:

[0026] • The curved handle features a curved body that tapers towards the far end, conforming to human grip habits;

[0027] • The line connecting the center of the third cylinder and the center of the first cylinder forms an angle of 115°–120°, allowing the handle to naturally extend to the optimal gripping position, enabling one-handed operation of gear switching and unlocking, greatly improving the efficiency of loading and unloading live seafood.

[0028] 4. Enhanced structural reliability:

[0029] • The buckle and the curved handle are molded as one piece, eliminating the risk of loosening of the connectors and withstanding frequent opening and closing;

[0030] • The closed-loop design of the elastic rope prevents the rope from falling off the male fastener, and the direction of the elastic force intelligently switches with the gear position to ensure effective locking force in both gear positions.

[0031] 5. Ease of maintenance and installation:

[0032] The arc-shaped protrusion of the female fastener serves as a guide structure, guiding the second cylinder to slide into the snap-fit ​​groove during installation, achieving blind insertion and alignment of the male and female fasteners, and reducing assembly difficulty; the elastic rope can be quickly replaced, and the maintenance cost is extremely low.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0046] Example

[0047] like Figures 1 to 11 As shown, this embodiment provides a lid buckle structure for a live seafood transport box, including a box body 1, a lid 2, and a multi-position buckle assembly 3 connecting the box body 1 and the lid 2.

[0048] The multi-position buckle assembly 3 includes:

[0049] Female fastener 31: such as Figure 10-11 As shown, the integrally formed connection to the side wall of the housing 1 includes a square protrusion 311 and a snap-fit ​​groove 312 on its bottom surface. The inner side of the snap-fit ​​groove 312 is a first groove side wall 312a, and the outer side is a second groove side wall 312b, with an abutment groove 313 formed at the connection between the two. An arc-shaped protrusion 314 is provided at the connection between the second groove side wall 312b and the outer side wall of the square protrusion 311.

[0050] Male fastener 32: such as Figure 6-9 As shown, the device includes a buckle body 321 and an arc-shaped handle 322, which are integrally injection molded and connected. The buckle body 321 consists of a first cylinder 321a (diameter D1), a second cylinder 321b (diameter D2, D1>D2), and a concave arc-shaped connecting body 321c. The three components form a first abutting arc surface 323 on the side away from the handle. The handle 322, the arc-shaped connecting body 321c, and the outer wall of the second cylinder 321b form a second abutting arc surface 324. The first cylinder 321a has a first through hole 325 concentric with itself. The arc-shaped main body 322a of the arc-shaped handle 322 gradually narrows towards the distal end, and a third cylinder 322b is provided at the end. The line L1 connecting the center of the third cylinder 322b and the center of the first cylinder 321a, and the line L2 connecting the center of the second cylinder 321b and the center of the first cylinder 321a, form an angle of 117° (within the range of 115°–120°).

[0051] Elastic rope 33: Made of solid rubber rope, it passes through the reserved hole of the box cover 2 and the first through hole 325 of the male fastener 32 in sequence and is then knotted to form a closed loop to prevent it from coming out of the first through hole 325.

[0052] Assembly and working process:

[0053] 1. Initial Installation:

[0054] The second cylinder 321b of the male fastener 32 is slid into the snap-fit ​​groove 312 along the arc-shaped protrusion 314 of the female fastener 31 to complete the connection of the male and female fasteners.

[0055] 2. First working position (transportation locked position):

[0056] like Figure 1-2 As shown, press down the curved handle 322 to its limit position. At this point:

[0057] The first abutting arc surface 323 of the male fastener 32 is in complete contact with the first groove sidewall 312a of the female fastener 31;

[0058] • The axis of the elastic rope segment 33 along the center of the first through hole to the bottom surface of the box cover is located to the left of the center of the second cylinder 321b. The axis of the elastic rope segment 33 forms a 45° angle with the line connecting the centers of the first and second cylinders (within the range of 40°–45°).

[0059] The tension of the elastic rope 33 forces the male fastener 32 to press tightly against the female fastener 31, forming the main locking force.

[0060] 3. Second operating mode (safety protection mode):

[0061] When the first gear position is accidentally activated and the handle 322 is pulled outward, such as Figure 3-4 As shown,

[0062] The male fastener 32 rotates around the abutment groove 313, and the second abutment arc surface 324 abuts against the side wall 312b of the second groove.

[0063] • The axis of the elastic rope 33 segment along the center of the first through hole to the bottom surface of the box cover is moved to the right side of the center of the second cylinder 321b. The axis of the elastic rope 33 segment forms a 3° angle with the line connecting the center of the cylinder (within the range of 0°–5°).

[0064] • The direction of the tension of the elastic rope 33 still keeps the male and female fasteners in a limiting connection, and the box cover 2 is in a closed state.

[0065] 4. Separation operation:

[0066] Continue to pull the arc-shaped handle 322 outward, so that the second abutting arc surface 324 slides along the trajectory of the arc-shaped protrusion 314, and the male fastener 32 is disengaged from the female fastener 31, thus opening the box cover 2.

[0067] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
