[0023] This utility model discloses a safety anti-detachment hook. A baffle limiting component allows the movable baffle to maintain a stable connection with the hanging section while also allowing it to move relative to the hanging section. When the movable baffle moves upwards to its bottom end near the hanging section, the opening is exposed, allowing the hanging section to be framed on the external support foundation through the opening. The movable baffle is then hung on the external support foundation, and the workpiece to be hoisted is hung on the hook section through the opening. When the movable baffle moves downwards to its bottom end contacting the hook section, the opening is closed. At this point, both the external support foundation within the area enclosed by the hanging section and the workpiece on the hook section can remain stably in their current positions, reducing the possibility of detachment due to the difference in center of gravity between the lifting point and the workpiece.

[0024] 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.

[0025] This disclosure provides an exemplary embodiment of a safety anti-detachment hook, such as... Figure 1 As shown, Figure 1 This is a schematic diagram illustrating a safety anti-detachment hook structure according to an exemplary embodiment; Figure 2 This is a schematic diagram illustrating the position of the lifting lugs according to an exemplary embodiment; Figure 3 This is illustrated according to an exemplary embodiment. Figure 2 The middle image is a schematic diagram showing the location of the fork-shaped structure. The following is a combination of... Figures 1 to 3 To explain.

[0026] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0027] Reference Figure 1 and Figure 2 This disclosure provides an exemplary embodiment of a safety anti-detachment hook, which includes:

[0028] Hook 1 includes a hanging section 11 for straddling an external support foundation, and a hook section 12 integrally formed below the hanging section 11 for hooking external devices. An opening 13 is formed between the hanging section 11 and the hook section 12 for the hanging section 11 to be erected on the external support foundation and / or for the external devices to be erected on the hook section 12.

[0029] The movable baffle 2 is slidably connected to the hook 1 and snapped into the hook 1 in the direction of the opening 13. The movable baffle 2 has a locked state in which the opening 13 is closed after the bottom end extends to the hook section 12, and an open state in which the opening 13 is opened after the bottom end is raised to the hanging section 11.

[0030] The baffle limiting member 5 is fixed to the hanging section 11 and movably connected to the movable baffle 2. The baffle limiting member 5 is used to prevent the movable baffle 2 from detaching from the hanging section 11 and to keep the movable baffle 2 in the open state.

[0031] For example, refer to Figure 1The hanging section 11 has a U-shaped structure with an opening 13 facing downwards, and a lifting lug 4 is integrally formed on the top side of the hanging section 11. The hook section 12 includes a vertically inclined section 121 fixed to the hanging section 11, and a horizontally supporting section 122 fixed to the vertically inclined section 121 and used for hanging external devices. The top end of the vertically inclined section 121 is integrally formed at one end of the hanging section 11, and the other end of the vertically inclined section 121 extends obliquely downwards and outwards relative to the hanging section 11. The horizontally supporting section 122 has an arc-shaped structure. One end of the horizontally supporting section 122 is integrally formed at the bottom end of the vertically inclined section 121, and the other end of the horizontally supporting section 122 extends along its own contour in a direction away from the vertically inclined section 121 and extends to the outside of the hanging section 11. An opening 13 is formed between the end of the horizontally supporting section 122 away from the vertically inclined section 121 and the end of the hanging section 11 away from the vertically inclined section 121. The U-shaped hanging section 11 with the opening 13 facing downwards allows the hook 1 to stably straddle and rest on the external support foundation, such as being hung, framed, or hoisted onto the beam. The vertically placed and inclined section 121 allows for a larger space below the hanging section 11 for fixing the workpiece. The horizontally placed and arc-shaped horizontal support section 122 suspends the workpiece and shifts it toward the center of the horizontal support section 122, thereby making the line connecting the center of gravity of the workpiece and the lifting point of the lifting lug 4 (or the line connecting the lifting points of the hanging section 11) closer to the vertical straight line, reducing the possibility of workpiece tilting.

[0032] A positioning sleeve 3 for mounting the movable baffle 2 is provided on the hanging section 11. The positioning sleeve 3 has a horizontal frame structure, and one side of the positioning sleeve 3 is integrally formed on the top side of the hanging section 11 away from the vertical inclined section 121. The movable baffle 2 is in a vertical position and is inserted into the positioning sleeve 3. Both ends of the movable baffle 2 extend from the top and bottom sides of the positioning sleeve 3, respectively. A sliding groove 21 is provided on the movable baffle 2 along its length and passes through it in the direction of the opening 13. The baffle limiting member 5 includes a bolt threaded to the side of the hanging section 11 away from the vertical inclined section 121. The baffle limiting member 5 passes through the sliding groove 21, and the head of the bolt, which serves as the baffle limiting member 5, protrudes from the side of the movable baffle 2 away from the vertical inclined section 121. The positioning sleeve 3 and the bolt, which serves as the baffle limiter 5, both provide a limiting function for the movable baffle 2. The positioning sleeve 3 and the baffle limiter 5 enable the movable baffle 2 to slide relative to the hanging section 11 while maintaining its connection with the hanging section 11, thereby realizing the opening and closing of the opening 13.

[0033] The bottom end of the slide 21 has a positioning groove 22 that is offset upwards at an angle. The positioning groove 22 is offset to one side and extends upwards from the bottom end of the slide 21, forming a top surface profile that is inclined relative to the length direction of the slide 21. Pulling the movable baffle 2 upwards causes the baffle limiting member 5 to slide relative to the movable baffle 2 within the slide 21. When the baffle limiting member 5 slides to the bottom end of the slide 21, it deflects the movable baffle 2, causing the baffle limiting member 5 to enter the positioning groove 22. After releasing the movable baffle 2, the movable baffle 2 moves downwards under the action of gravity, and the baffle limiting member 5 can abut against the inclined top wall in the aforementioned positioning groove 22, thereby providing a supporting effect to the movable baffle 2. At this time, the movable baffle 2 is in an inclined posture and in an open state, with the opening 13 exposed between the bottom end of the movable baffle 2 and the end of the horizontally placed bearing section 122.

[0034] Additional references Figure 3 The bottom end of the movable baffle 2 has a fork-shaped structure 23. The opening 13 in the middle of the fork-shaped structure 23 is larger than the thickness of the horizontal bearing section 122. By deflecting the movable baffle 2, the movable baffle 2 is restored to a vertical position, causing the baffle limiting member 5 to disengage from the positioning groove 22 and enter the sliding groove 21. At this time, the movable baffle 2 is moved downward, and the fork-shaped structure 23 at the bottom end of the movable baffle 2 moves toward the horizontal bearing section 122 and straddles the horizontal bearing section 122. The horizontal bearing section 122 supports the movable baffle 2. At this time, the movable baffle 2 is in a vertical position and blocks the opening 13. The movable baffle 2 is in a locked state.

[0035] In this embodiment, there is a gap between the movable baffle 2 and the hook section 12 for the movable baffle 2 to swing, so as to facilitate the application of force to the movable baffle 2 so that it can be more smoothly separated from the horizontal bearing section 122, or so that the baffle limiting member 5 can be more smoothly separated from the positioning groove 22.

[0036] The baffle limiting component 5 ensures that the movable baffle 2 maintains a stable connection with the hanging section 11 while also allowing the movable baffle 2 to move relative to the hanging section 11. When the movable baffle 2 moves upward to its bottom end near the hanging section 11, the opening 13 is exposed, allowing the hanging section 11 to be framed on the external bearing foundation through the opening 13. By moving, the hanging section 11 is hung on the external bearing foundation, and the external workpiece to be hoisted is hung on the hook section 12 through the opening 13. When the movable baffle 2 moves downward to its bottom end contacting the hook section 12, the opening 13 is closed by the movable baffle 2. At this time, the external bearing foundation within the area enclosed by the hanging section 11 and the workpiece on the hook section 12 can both remain stably in their current positions, reducing the possibility of disengagement due to the difference between the center of gravity of the hoisting point and the center of gravity of the workpiece.

[0037] In an exemplary embodiment of this disclosure, reference is made to Figure 1 and Figure 3The end of the horizontal bearing section 122 has a stop 14 extending toward the opening 13. When the movable baffle 2 is in the locked state, the stop 14 is located on one side of the bottom end of the movable baffle 2 and prevents the movable baffle 2 from disengaging from the end of the horizontal bearing section 122.

[0038] For example, refer to Figure 1 and Figure 3 The stop block 14 is integrally formed on one end of the horizontal bearing section 122 away from the vertical inclined section 121 and is in a vertical position. Since there is a gap between the movable baffle 2 and the hook section 12 for the movable baffle 2 to swing, the movable baffle 2 can deflect in the direction away from the vertical inclined section 121. The stop block 14 can reduce the possibility of the movable baffle 2 detaching from the end of the horizontal bearing section 122 away from the vertical inclined section 121.

[0039] In this embodiment, the fork-shaped structure 23 has outwardly extending and symmetrically arranged ears 25. There are two ears 25, which are respectively disposed on the two fork arms of the fork-shaped structure 23. Both ears 25 extend outwardly in a direction away from the fork-shaped structure 23. The ears 25 enable the movable baffle 2 in the locked state to stay more stably on the current position on the horizontal bearing section 122, so as to achieve stable closure of the opening 13.

[0040] In an exemplary embodiment of this disclosure, reference is made to Figure 1 The fork-shaped structure 23 is provided with a sloping guide portion 24, which is located on the inner side wall of the fork-shaped structure 23 and makes the bottom end of the fork-shaped structure 23 flared.

[0041] For example, refer to Figure 1 The inclined guide portion 24 is formed inside the opening 13 of the fork-shaped structure 23 and is disposed on the two fork arm entities of the fork-shaped structure 23. The top side of the inclined guide portion 24 extends downward from the side wall of the fork arm entity to the bottom surface of the fork arm entity. In order to allow the bottom end of the movable baffle 2 to be more smoothly mounted on the transverse bearing section 122, the inclined guide portion 24 can also extend to the ear portion 25.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
