Description

Technical Field

[0001] This invention relates to the field of anchoring technology, and more particularly to a flip-top type ground anchor for aprons. Background Technology

[0002] Separable ground anchors (also known as "ground anchor covers") are mainly used to protect aircraft mooring anchors at airports and to protect pedestrians. When the anchors are not in use, the ground anchor cover is installed to prevent people from accidentally stepping into the pit and getting injured; to prevent water accumulation in the anchor pit from corroding and contaminating the anchors; to prevent water accumulation in the anchor pit from freezing and rendering the anchors unusable; and to prevent damage to the tires of passing vehicles.

[0003] The existing split ground anchor consists of two parts: the ground anchor cover plate and the ground anchor base. When in use, the ground anchor cover plate needs to be removed from the ground anchor base and placed aside. In extreme weather conditions, the ground anchor cover plate also needs to be collected and stored (most airports collect and store the ground anchor cover plate regardless of the weather).

[0004] The process of opening and installing this type of ground anchor is quite complicated, and it requires centralized collection, which increases the amount of manual labor. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a flip-type ground anchor for aprons. By transforming the traditional separate structure of the ground anchor into an integrated assembly structure, the spring-loaded flipping structure enables the ground anchor cover to flip during the opening and closing process relative to the ground anchor base. The use of a lock core assembly and a fixing hook assembly enables the ground anchor cover to be locked relative to the ground anchor base. This improves the ease of operation and safety of the ground anchor, and the ground anchor cover does not need to be retracted, reducing manual labor.

[0006] To achieve the above objectives, the present invention provides an apron flip-type ground anchor, comprising: a ground anchor base, a ground anchor cover plate, a spring-loaded flip structure, a lock core assembly, and a fixing hook assembly;

[0007] The ground anchor base is set on the apron ground, and the mooring anchor bar is installed inside the ground anchor base;

[0008] The ground anchor cover plate is hinged to one side of the ground anchor base via the spring-loaded flip structure and covers the ground anchor base. The ground anchor cover plate can be flipped relative to the spring-loaded flip structure.

[0009] The lock cylinder assembly includes a lock cylinder hook and a lock cylinder latch. The lock cylinder hook and the lock cylinder latch are respectively installed on the ground anchor base and the ground anchor cover plate at the positions corresponding to the spring-loaded flip structure. When the ground anchor cover plate is placed downward on the ground anchor base, the lock cylinder hook and the lock cylinder latch lock each other.

[0010] The fixed hook assembly includes a fixed hook and a fixed plate. The fixed hook and the fixed plate are respectively installed on the other side of the ground anchor base and the ground anchor cover plate away from the spring-loaded flip structure. When the ground anchor cover plate is placed downward on the ground anchor base, the fixed hook and the fixed plate are fixed to each other.

[0011] In the above technical solution, preferably, the spring-loaded flipping structure includes a rotating shaft, a spring, and a pressure chamber. The pressure chamber is a groove structure opened in the ground anchor base. The spring is disposed in the pressure chamber. The rotating shaft is installed in the pressure chamber and the bottom end of the rotating shaft is fixedly connected to the top end of the spring.

[0012] When the rotating shaft is pressed down by an external force to overcome the elastic force of the spring, the lock core assembly is locked, which can put the spring in a compressed state.

[0013] When the lock cylinder assembly is released, the rotating shaft can be lifted by the elastic force of the spring, causing the ground anchor cover to spring up synchronously.

[0014] In the above technical solution, preferably, while the rotating shaft lifts the ground anchor cover plate, the fixed hook and the fixed plate can be disengaged from each other and released from their fixed state.

[0015] In the above technical solution, preferably, the rotating shaft adopts an L-shaped rotating shaft structure, the bottom of the rotating shaft is set along the chamber wall of the pressure chamber, the top of the rotating shaft is L-shaped, a central shaft is installed at the end of the L-shaped rotating shaft, and the ground anchor cover plate is hinged to the central shaft.

[0016] In the above technical solution, preferably, the rotating shaft adopts a straight rotating shaft structure, the bottom of the rotating shaft is arranged along the chamber wall of the pressure chamber, the top of the rotating shaft is equipped with a central shaft, and the ground anchor cover plate is hinged to the central shaft.

[0017] In the above technical solution, preferably, the lock cylinder assembly further includes a push-lock structure, which is disposed in the through hole of the ground anchor cover plate. The lock cylinder hook or the lock cylinder latch is installed at the bottom of the through hole. The push-lock structure is connected to the lock cylinder hook or the lock cylinder latch. When the lock cylinder hook and the lock cylinder latch are locked together, pressing the push-lock structure can release the locking state of the lock cylinder hook and the lock cylinder latch.

[0018] In the above technical solution, preferably, a button plug is provided above the push-lock structure. The button plug is sealed relative to the through hole. When the button plug is pressed, it can drive the push-lock structure below to move downward synchronously, thereby directly releasing the locking state of the lock cylinder assembly.

[0019] In the above technical solution, preferably, the pressing lock structure adopts an impact lock structure, and the upper end of the impact lock structure is snapped onto the ground anchor cover plate.

[0020] In the above technical solution, preferably, an exhaust hole is provided through the ground anchor cover plate, and a waterproof and breathable valve is provided in the exhaust hole.

[0021] In the above technical solution, preferably, a waterproof rubber plug is provided at the contact edge between the ground anchor cover plate and the ground anchor base, and the waterproof rubber plug is a funnel-shaped rubber ring.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: by changing the traditional separate structure of the ground anchor to an integrated assembly structure, the spring-loaded flipping structure can realize the flipping of the ground anchor cover plate relative to the ground anchor base during the opening and closing process, and the use of the lock core assembly and the fixed hook assembly can realize the locking state of the ground anchor cover plate relative to the ground anchor base, which improves the simplicity of the ground anchor operation process, improves the safety of the ground anchor, and the ground anchor cover plate does not need to be retracted, reducing the amount of manual labor.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings:

[0035] like Figures 1 to 3 As shown, an apron flip-type ground anchor provided by the present invention includes: ground anchor base 1, ground anchor cover plate 2, spring-loaded flip structure 3, lock core assembly and fixing hook assembly;

[0036] The ground anchor base 1 is set on the apron ground, and the anchor bar is installed inside the ground anchor base 1;

[0037] The ground anchor cover 2 is hinged to one side of the ground anchor base 1 through the spring-loaded flip structure 3 and covers the ground anchor base 1. The ground anchor cover 2 can be flipped relative to the spring-loaded flip structure 3.

[0038] The lock cylinder assembly includes a lock cylinder hook 4 and a lock cylinder plate 5. The lock cylinder hook 4 and the lock cylinder plate 5 are respectively installed on the ground anchor base 1 and the ground anchor cover plate 2 at the positions corresponding to the spring-loaded flip structure 3. When the ground anchor cover plate 2 is placed downward on the ground anchor base 1, the lock cylinder hook 4 and the lock cylinder plate 5 are locked together.

[0039] The fixed hook assembly includes a fixed hook 7 and a fixed tab 8. The fixed hook 7 and the fixed tab 8 are respectively installed on the ground anchor base 1 and the ground anchor cover plate 2 on the other side away from the spring-loaded flip structure 3. When the ground anchor cover plate 2 is placed downward on the ground anchor base 1, the fixed hook 7 and the fixed tab 8 are fixed to each other.

[0040] In this embodiment, by changing the traditional separate structure of the ground anchor to an integrated assembly structure, the spring-loaded flipping structure 3 enables the ground anchor cover 2 to flip relative to the ground anchor base 1 during the opening and closing process. The lock core assembly and the fixed hook assembly enable the ground anchor cover 2 to be locked relative to the ground anchor base 1. This improves the simplicity of the ground anchor operation process and enhances the safety of the ground anchor. Moreover, the ground anchor cover 2 does not need to be retracted, reducing the amount of manual labor.

[0041] Specifically, when the anchor bar needs to be used, the anchor cover plate 2 is released from the locking state of the new locking component relative to the anchor base 1, the mutual fixing state of the fixing hook component is released, and the anchor cover plate 2 is flipped open around the spring-loaded flipping structure 3, thereby exposing the anchor bar installed in the anchor base 1 and realizing the normal use of the anchor bar. Preferably, the anchor cover plate 2 can be flipped 180 degrees relative to the anchor base 1.

[0042] like Figures 4 to 8 As shown, after the anchor bar is used and retracted to the ground anchor base 1, the ground anchor cover plate 2 is flipped around the spring-loaded flipping structure 3 to cover the ground anchor base 1. First, one side of the fixed hook assembly is pressed down so that the fixed hook 7 and the fixed plate 8 are fixed to each other. Then, the ground anchor cover plate 2 is flattened as a whole and the lock core hook 4 and the lock core plate 5 are locked to each other to close the ground anchor.

[0043] like Figure 3 and Figure 8 As shown, in the above embodiment, preferably, the spring-loaded flip structure 3 includes a rotating shaft 31, a spring 32 and a pressure chamber 33. The pressure chamber 33 is a groove structure opened in the ground anchor base 1. The spring 32 is disposed in the pressure chamber 33. The rotating shaft 31 is installed in the pressure chamber 33 and the bottom end of the rotating shaft 31 is fixedly connected to the top end of the spring 32.

[0044] When the external force overcomes the elastic force of the spring 32 and presses down the rotating shaft 31, the lock core assembly is locked, which can keep the spring 32 in a compressed state.

[0045] When the lock cylinder assembly is released from the locked state, the rotating shaft 31 can be lifted up by the elastic force of the spring 32, causing the ground anchor cover 2 to spring up synchronously.

[0046] In this embodiment, the spring-loaded flipping structure 3 not only enables the hinged connection between the anchor cover plate 2 and the anchor base 1, but also provides lifting and lowering motion under the elastic force of the spring 32 in the vertical direction. Under the elastic force of the spring 32, once the lock cylinder assembly is released, the anchor cover plate 2 can be directly lifted relative to the anchor base 1 without any other external force obstruction. This eliminates the need for manual lifting or hooking of the anchor cover plate 2, reducing manual workload and improving the opening efficiency of the anchor cover plate 2.

[0047] The pressure chamber 33 is mainly used to house the spring 32 and the rotating shaft 31. The spring 32 can provide power for lifting the ground anchor cover 2, and can also be retracted when manual downward force is applied, which is convenient and quick.

[0048] like Figure 4 As shown, in the above embodiment, preferably, while the rotating shaft 31 lifts the ground anchor cover plate 2, the fixed hook 7 and the fixed plate 8 can disengage from each other and be released from their fixed state. This is because the spring-loaded flipping structure 3 and the fixed hook 7 are respectively arranged on both sides of the ground anchor cover plate 2. When the spring 32 lifts the rotating shaft 31 on one side, the ground anchor cover plate 2 will be tilted. At this time, an angle will naturally appear between the fixed hook 7 and the fixed plate 8 on the other side, which can release the fixed state between the fixed hook 7 and the fixed plate 8.

[0049] In the above embodiments, preferably, the rotating shaft 31 can be configured in two ways, specifically including:

[0050] (1) The rotating shaft 31 adopts an L-shaped rotating shaft structure. The bottom of the rotating shaft 31 is set along the wall of the pressure chamber 33, and the top of the rotating shaft 31 is L-shaped. The end of the L-shaped rotating shaft 31 is equipped with a central shaft, and the ground anchor cover plate 2 is hinged to the central shaft.

[0051] (2) The rotating shaft 31 adopts a straight rotating shaft structure. The bottom of the rotating shaft 31 is set along the wall of the pressure chamber 33, and the top of the rotating shaft 31 is equipped with a central shaft. The ground anchor cover plate 2 is hinged to the central shaft.

[0052] In the two types of shaft 31 structures mentioned above, attention should be paid to the design of the flipping and avoidance structure. That is, the design of the shaft 31 should not affect the flipping process of the ground anchor cover plate 2 relative to the ground anchor base 1, so as to ensure that the ground anchor cover plate 2 can be flipped 180 degrees relative to the ground anchor base 1.

[0053] In the above embodiment, preferably, the lock cylinder assembly further includes a press-lock structure 6, which is disposed in the through hole of the ground anchor cover plate 2. The lock cylinder hook 4 or lock cylinder latch 5 is installed at the bottom of the through hole, and the press-lock structure 6 is connected to the lock cylinder hook 4 or lock cylinder latch 5. Preferably, while the ground anchor cover plate 2 is locked relative to the ground anchor base 1, the press-lock structure 6 can be locked by the impact of the lock cylinder assembly. When the lock cylinder hook 4 and lock cylinder latch 5 are locked together, pressing the press-lock structure 6 can release the locking state of the lock cylinder hook 4 and lock cylinder latch 5. At this time, the ground anchor cover plate 2 can spring up under the elastic force of the spring 32.

[0054] In the above embodiment, preferably, a button plug 9 is provided above the push-lock structure 6. The button plug 9 is sealed relative to the through hole to achieve waterproofing and pollution prevention. When the button plug 9 is pressed, it can drive the push-lock structure 6 below to move downwards simultaneously, thereby directly releasing the locking state of the lock cylinder assembly. In this way, when it is necessary to open the ground anchor cover 2, the push-lock structure 6 can be triggered to open without removing the button plug 9.

[0055] In the above embodiments, preferably, the press lock structure 6 adopts an impact lock structure, and the upper end of the impact lock structure is engaged with the ground anchor cover plate 2.

[0056] In the above embodiment, preferably, a vent hole 10 is provided through the ground anchor cover plate 2, and a waterproof and breathable valve is provided inside the vent hole 10. The vent hole 10 can balance the air pressure inside the cavity. When the air pressure inside and outside the cavity is inconsistent, making it difficult to open the cover plate, the vent hole 10 can balance the air pressure inside and outside the cavity, so as to prevent the ground anchor cover plate 2 from being unable to be opened due to low air pressure inside the cavity. The waterproof and breathable valve can both allow air to pass through and keep the cover waterproof at the same time.

[0057] In the above embodiment, preferably, a waterproof plug 11 is provided at the contact edge between the ground anchor cover plate 2 and the ground anchor base 1. The waterproof plug 11 is a flared rubber ring. The waterproof plug 11 can waterproof the contact area between the ground anchor cover plate 2 and the ground anchor base 1, preventing rainwater and other substances from entering the ground anchor base 1 and causing the anchor bars to rust.

[0058] According to the above-described embodiment of the apron flip-type ground anchor, during implementation, the ground anchor cover 2 is in the open state, the spring 32 in the pressure chamber 33 is in the depressurized state, the rotating shaft 31 springs up, and the ground anchor cover 2 can be flipped around the rotating shaft 31 in this state.

[0059] During the closing process, first place the anchor cover 2 near the fixing plate 8 into the anchor base 1. Step on the anchor cover 2 on that side to engage the fixing hook 7 under the fixing plate 8, thus fixing the fixing hook 7 relative to the fixing plate 8. Then, step vertically downward on the anchor cover 2 near the lock cylinder assembly to engage the lock cylinder hook 4 under the lock cylinder plate 5, thus locking the anchor cover 2 relative to the anchor base 1. At this time, the spring 32 in the pressure chamber 33 changes from a depressurized state to a compressed state.

[0060] During the opening process, press the button plug 9 with a tool. The button plug 9 simultaneously triggers the press lock structure 6, causing the lock cylinder hook 4 to retract and disengage from the lock cylinder latch 5, thus releasing the locking state. At this time, the spring 32 in the pressure chamber 33 is released, lifting the rotating shaft 31, which in turn lifts the ground anchor cover 2. At this time, the ground anchor cover 2 is tilted, and the fixing state between the fixed hook 7 and the fixed latch 8 is released, allowing the entire ground anchor cover 2 to be flipped open around the rotating shaft 31.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
