TECHNICAL FIELD
[0001] The utility model relates to the field of daily utensils, concretely relates to a gravity self -locking type anti -drop hook. BACKGROUND
[0002] In modern life, hooks as a basic and commonly used tool are widely used in various scenes. For example, in a home environment, hooks are fixed on the wall surface, wardrobe and other vertical surfaces, which can hang clothes, bags, shopping bags and other daily necessities, or in a mobile space such as a vehicle or a ship, hooks can hang various items to make full use of the space.
[0003] However, the common hooks on the market usually adopt a fixed shape curved structure, which has obvious limitations. Since the opening width is relatively fixed, the thickness range of the hanging piece that can be supported is very limited. Once the thickness of the hanging piece exceeds the adaptive range of the hook opening, only the limited friction force between the hook and the hanging piece can maintain the suspended state. As long as it is touched, the item is easy to slip off the hook, which brings many inconveniences to the user, and even may cause damage to the item.
[0004] When the hook is applied to a mobile space such as a vehicle or a ship, the vehicle will sway due to the road conditions during driving, and the ship will sway due to the influence of wind and waves during sailing. The hook will constantly sway. In this dynamic environment, even if the thickness of the hanging piece is within the normal adaptive range of the hook, the items on the hook are also very easy to fall off due to the inertial force caused by the sway, thereby affecting the storage of the items, and even may cause accidental injury to other items or personnel during the sway.
[0005] In summary, the existing hook has obvious deficiencies in dealing with the thickness diversity of the hanging piece and the instability of the space environment. SUMMARY
[0006] Therefore, the utility model provides a gravity self -locking type anti -drop hook, which can automatically close the hook opening after hanging objects, effectively preventing the objects from falling off.
[0007] To achieve the above purpose, the technical scheme of the utility model is as follows:
[0008] A gravity self -locking type anti -drop hook, the key lies in: including the mounting plate, one side of the mounting plate is provided with the suspension assembly, the suspension assembly includes the hook, the closing rod and the linkage rod, the inner end of the hook is rotatably connected to the mounting plate, the outer end has a hook portion, the inner end of the closing rod is rotatably connected to the mounting plate, and the linkage rod is hingedly connected to the middle part of the hook and the closing rod at both ends;
[0009] The closing rod is located above the hook; when the hook is turned downward to the vertical state, the outer end of the closing rod can be pressed on the hook portion under the driving action of the linkage rod, so that the outer end of the hook is in a closed state; when the hook is turned upward from the vertical to the horizontal state, the outer end of the closing rod can be moved upward away from the hook portion under the driving action of the linkage rod;
[0010] Further comprising an elastic component, which is applied with a force to turn the hook from the vertical to the horizontal state.
[0011] With the above structure, in the non-use state, the elastic force of the elastic component can keep the hook outer end and the closing rod in an open state, at this time, the article can be hung on the hook portion through the gap. When the hook portion is hung with the article, the gravity of the article acts on the hook, so that the hook is turned downward around the connecting point of the hook and the mounting plate, the downward turning of the hook can be transmitted to the closing rod through the linkage rod, thereby driving the closing rod to turn downward around the connecting point of the closing rod and the mounting plate, and the outer end of the hook portion and the closing rod can be closed under the action of gravity, that is, the outer end of the hook is in a closed state, thereby effectively avoiding the article from falling off the hook portion. When the article needs to be taken out, the article is lifted upward away from the hook portion, under the elastic force of the elastic component, the hook is turned upward, which can be transmitted to the closing rod through the linkage rod, thereby driving the closing rod to turn upward, and at the same time, the elastic force of the elastic component can restore the hook outer end and the closing rod to the open state, so that the article can be taken out from the hook portion.
[0012] As a preferred, the hook and the closing rod are sequentially arranged along the height direction of the mounting plate, the inner end of the hook is rotationally connected to the mounting plate through a first mounting seat, and the inner end of the closing rod is rotationally connected to the mounting plate through a second mounting seat. With the above structure, assembly is facilitated.
[0013] As a preferred, the elastic component is arranged between the hook and the mounting plate, or between the hook and the closing rod, or between the closing rod and the mounting plate. With the above structure, the elastic component can provide a power source for the upward turning of the hook and the closing rod.
[0014] As a preferred, the elastic component is a tension spring, one end of which is hung on the second mounting seat, and the other end is hung on the middle part of the hook. With the above structure, in the non-use state, the elastic component is in a stretched state, which provides an outward opening tension for the hook, so as to keep a certain opening angle between the hook portion and the closing rod. When the article is hung on the hook portion, the hook can overcome the tension of the elastic component and turn downward around the connecting point of the hook and the mounting plate under the action of gravity, and then drive the closing rod to turn downward through the linkage rod, thereby realizing self-locking of the hook. After the article is taken off, the elastic component returns to the original state, thereby driving the hook to turn upward, and driving the closing rod to turn upward under the transmission of the linkage rod, so that the hook and the closing rod return to the initial state.
[0015] As preferred: the elastic component is a compression spring, one end of which is connected to the lower side of the hook, and the other end of which is supported on the mounting plate. With the above structure, in the non-use state, the elastic component is in a pre-compressed state, which provides an upward elastic force for the hook to keep a certain opening angle between the hook portion and the closure rod, facilitating the hanging of the article. When the article is hung on the hook portion, the hook rotates downward around the connecting point with the mounting plate under the action of gravity, at this time, the elastic component is compressed and elastically deformed to store elastic potential energy. After the article is removed, the elastic component releases the elastic force to push the hook to rotate upward to return to the initial open state.
[0016] As preferred: the length of the closure rod is greater than the length of the hook, and the structure of the outer end of the closure rod is adapted to the outer profile of the hook portion. With the above structure, the closing effect of the open end of the hook is ensured.
[0017] As preferred: a first slot is provided on the hook, a second slot is provided on the closure rod, and the two ends of the linkage rod are rotatably installed in the first slot and the second slot respectively. With the above structure, by changing the positions of the two ends of the linkage rod in the first slot and the second slot, the length of the force arm of the hook and the closure rod around the connecting point with the mounting plate can be changed, so that the load bearing capacity of the hook portion can be changed.
[0018] As preferred: the first slot is provided on the upper part of the hook, and the second slot is provided on the upper part of the closure rod. With the above structure, the stability of the overall structure of the hook can be ensured, and the hook can more stably hang the article during use.
[0019] As preferred: when the outer end of the closure rod is pressed on the hook portion, there is a gap between the hook and the mounting plate. With the above structure, the design of the gap can reduce the direct contact between the hook and the mounting plate, reduce the possibility of wear and tear, prolong the service life of the hook, and on the other hand, ensure that the closure of the hook and the outer end of the closure rod is not interfered.
[0020] As preferred: the hook and the closure rod are made of high-strength metal material or high-strength plastic. With the above structure, the weight of the product can be reduced, the cost can be reduced, and the durability of the product can be improved.

[0022] 1. The gravity self-locking anti-falling hook provided by the utility model, since the hook and the inner end of the closing rod are both rotationally connected to the mounting plate, the two ends of the linkage rod are rotationally connected to the hook and the closing rod respectively, therefore, a movable linkage structure is formed between the hook, the closing rod and the linkage rod. In the non-use state, the elastic force exerted by the elastic component can keep the hook outer end and the closing rod in an open state, that is, the outer end of the hook portion and the closing rod have a gap, at this time, the article can be hung into the hook portion through the gap. When the hook portion hangs the article, the gravity of the article acts on the hook, so that the hook rotates downward around the connecting point with the mounting plate, the downward rotation of the hook can be transmitted to the closing rod through the linkage rod, thereby driving the closing rod to rotate downward around the connecting point with the mounting plate, and the outer end of the hook portion and the closing rod can be closed under the action of gravity, that is, the outer end of the hook is in a closed state, thereby effectively preventing the article from falling off the hook portion.

[0031] The utility model is further explained below in combination with the embodiments and the drawings.
[0032] As shown in Figure 1 , a gravity self-locking anti-falling hook, comprising a mounting plate A, a hanging assembly and an elastic component 4, wherein the mounting plate A is used for fixedly connected at the position where the hook is needed to be used. The hanging assembly is arranged at one side of the mounting plate A, and the hanging assembly comprises a hook 1, a closing rod 2 and a linkage rod 3 between the hook 1 and the closing rod 2. The inner end of the hook 1 is rotatably connected to the mounting plate A, and the outer end of the hook 1 has a hook portion 11, which is used for hanging articles. The inner end of the closing rod 2 is rotatably connected to the mounting plate A, and the two ends of the linkage rod 3 are respectively hinged to the middle part of the hook 1 and the closing rod 2. In the embodiment, the closing rod 2 is above the hook 1. Referring to Figure 3 , when the hook 1 is rotated downward to the vertical state, the outer end of the closing rod 2 can be pressed on the hook portion 11 under the driving action of the linkage rod 3, so that the outer end of the hook 1 is in a closed state. Referring to Figure 2 , the elastic component 4 applies a force to rotate the hook 1 from the vertical state to the horizontal state. When the hook 1 is rotated upward from the vertical state to the horizontal state, the outer end of the closing rod 2 can be away from the hook portion 11 upward under the driving action of the linkage rod 3, so that the outer end of the hook 1 and the closing rod 2 are in an open state.
[0033] Based on the above structure design, the working principle of the gravity self-locking anti-falling hook provided by the embodiment is as follows: since the inner ends of the hook 1 and the closing rod 2 are rotatably connected to the mounting plate A, and the two ends of the linkage rod 3 are rotatably connected to the hook 1 and the closing rod 2, an active linkage structure is formed between the hook 1, the closing rod 2 and the linkage rod 3. In the unused state, the elastic force of the elastic component 4 can keep the outer end of the hook 1 and the closing rod 2 in an open state, that is, there is a gap between the outer end of the hook portion 11 and the closing rod 2. At this time, the article can be hung into the hook portion 11 through the gap. When the hook portion 11 hangs the article, the gravity of the article acts on the hook 1, so that the hook 1 rotates downward around the connecting point of the hook 1 and the mounting plate A. The downward rotation of the hook 1 can be transmitted to the closing rod 2 through the linkage rod 3, so as to drive the closing rod 2 to rotate downward around the connecting point of the closing rod 2 and the mounting plate A. The outer end of the hook portion 11 and the closing rod 2 can be closed under the action of gravity, that is, the outer end of the hook 1 is in a closed state, thereby effectively avoiding the article from falling off the hook portion 11. When the article needs to be taken out, the article is lifted upward away from the hook portion 11. Under the action of the elastic force of the elastic component 4, the hook 1 rotates upward, which can be transmitted to the closing rod 2 through the linkage rod 3, so as to drive the closing rod 2 to rotate upward. At the same time, the elastic force of the elastic component 4 can restore the outer end of the hook 1 and the closing rod 2 to an open state, and the article can be taken out from the hook portion 11.
[0034] Compared with the traditional structure of the hook, the outer end of the closing rod 2 is pressed on the bent hook part 11, the hook 1 is closed, the article is locked in the structure surrounded by the hook 1 and the closing rod 2, the article is effectively prevented from falling off from the hook due to shaking, touching and the like, the stability and practicability of the hook are improved, the gravity self-locking type anti-falling hook provided by the embodiment can reliably fix the article in a static home environment, a dynamic vehicle, a ship or the like, or when the thickness of the hanging part is greater than the width of the bent hook part 11, and has the technical advantages of wide use range and high use convenience.
[0035] By Figure 1 As can be seen, the hook 1 and the closing rod 2 are sequentially arranged along the height direction of the mounting plate A, the mounting plate A is provided with a first mounting seat A1 and a second mounting seat A2 extending outward, the inner end of the hook 1 is rotationally connected to the mounting plate A through the first mounting seat A1, and the inner end of the closing rod 2 is rotationally connected to the mounting plate A through the second mounting seat A2. Such a design facilitates assembly.
[0036] In the embodiment, the mounting position of the elastic component 4 can be arranged between the hook 1 and the mounting plate A, or the elastic component 4 is arranged between the closing rod 2 and the mounting plate A, or the elastic component 4 is arranged between the hook 1 and the closing rod 2. The above three mounting modes of the elastic component 4 can provide a power source for the upward rotation of the hook 1 and the closing rod 2, and realize the automatic reset function.
[0037] Please refer to Figure 2 The elastic component 4 is a tension spring, one end of the tension spring is hung on the second mounting seat A2, and the other end is hung in the middle of the hook 1. In the non-use state, the elastic component 4 is in a stretched state, which provides an outward opening tension for the hook 1, so as to maintain a certain opening angle between the bent hook part 11 and the closing rod 2. When the article is hung on the bent hook part 11, the hook 1 can overcome the tension of the elastic component 4 and rotate downward around the rotation joint with the mounting plate A under the action of gravity, and then drive the closing rod 2 to rotate downward through the linkage rod 3, so as to realize the self-locking of the hook. After the article is removed, the elastic component 4 returns to the original state, drives the hook 1 to rotate upward, and drives the closing rod 2 to rotate upward through the transmission of the linkage rod 3, so as to make the hook 1 and the closing rod 2 return to the initial state.
[0038] Reference Figure 4When the elastic component 4 is a compression spring, one end of the compression spring is connected to the lower side of the hook 1, and the other end is supported on the mounting plate A. In the unused state, the elastic component 4 is in a pre-compressed state, which provides an upward elastic force for the hook 1 to maintain a certain opening angle between the hook portion 11 and the closing rod 2, facilitating the hanging of objects. When an object is hung on the hook portion 11, the hook 1 rotates downward around the hinge point with the mounting plate A under the action of gravity, at which time the elastic component 4 is compressed and elastically deformed, storing elastic potential energy. After the object is removed, the elastic component 4 releases the elastic force and pushes the hook 1 to rotate upward to return to the initial open state.
[0039] As shown in Figure 2 and 3 , in order to ensure the closing effect of the open end of the hook 1, in the present embodiment, the length of the closing rod 2 is greater than the length of the hook 1, and the structure of the outer end of the closing rod 2 is adapted to the outer profile of the end portion of the hook portion 11. In this way, when the outer end of the closing rod 2 is pressed on the hook portion 11, the fit between the outer end of the closing rod 2 and the outer end of the hook portion 11 can be more closely, further improving the stability and applicability of the hook.
[0040] As shown in Figure 1 , 5 and 6, the hook 1 is provided with a first slot 12, and the closing rod 2 is provided with a second slot 21, and the two ends of the linkage rod 3 are respectively rotatably connected in the first slot 12 and the second slot 21 through a pin shaft. In this way, both the first slot 12 and the second slot 21 are long strip structures, and by changing the positions of the two ends of the linkage rod 3 in the first slot 12 and the second slot 21, the length of the force arm of the hook 1 and the closing rod 2 around the hinge point of the mounting plate A can be changed, thereby the load-bearing capacity of the hook portion 11 can be changed. The advantage of such a structural design is that it can quickly customize hooks with different load-bearing capacities without the need for large-scale changes in product design and production process, improving production efficiency and flexibility.
[0041] As shown in Figure 1 , 5 and 6, the first slot 12 is opened at the upper part of the hook 1, that is, the end of the hook 1 close to the mounting plate A, and the second slot 21 is opened at the upper part of the closing rod 2. In this way, the stability of the overall structure of the hook can be ensured, and the hook can be more stably hung during use.
[0042] In the present embodiment, the first slot 12 is opened at the upper part, and the upper end of the first slot 12 is rotatably connected to the first mounting seat A1 through a pin shaft. The second slot 21 is opened at the upper part, and the upper end of the second slot 21 is rotatably connected to the second mounting seat A2 through a pin shaft. In this way, it has the advantages of convenient production and installation.
[0043] Please refer to Figure 3When the outer end of the hook 1 and the closing rod 2 falls under the gravity, the outer end of the closing rod 2 presses on the hook portion 11, and there is a gap a between the hook 1 and the mounting plate A. The design of the gap a can reduce the direct contact between the hook 1 and the mounting plate A, reduce the possibility of wear and tear, prolong the service life of the hook, and on the other hand, ensure that the closure of the outer end of the hook 1 and the closing rod 2 is not interfered.
[0044] In the embodiment, the inner side of the closing rod 2 is provided with anti-skid lines, which can increase the friction between the hook portion 11 and the suspended object, so that the object is more stable when suspended and is not easy to slip.
[0045] In the embodiment, the hook 1 and the closing rod 2 are made of high-strength metal materials, which have high load-bearing capacity and good wear resistance and corrosion resistance, thereby improving the durability of the product.
[0046] Alternatively, the hook 1 and the closing rod 2 are made of high-strength plastic, which can reduce the weight of the product and improve the appearance of the product, and has the advantages of low cost and high design flexibility.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present application, and those skilled in the art can make various similar expressions under the inspiration of the present application without violating the purpose and claims of the present application. Such changes fall within the scope of the present application.
