Description

Technical Field

[0001] The invention relates to the technical field of bottle commodity protection, in particular to a bottle protection cover. Background Art

[0002] With the widespread popularity of shopping malls, the consumption of bottled goods such as bottled wine is increasing, and the number of cases of unauthorized destruction of sealed bottle caps for stealing is also increasing. In order to effectively protect bottled goods, the prior art proposes a bottle protection cover with a clamp arm. When the bottle mouth of the bottle is inserted into the bottle protection cover (accommodation cavity), the clamp arm can be used to limit the bottle mouth, thereby playing an anti-destruction role for the bottle cap. However, the clamp arm provided in the bottle protection cover of the prior art is usually limited by translating in a certain direction to achieve the conversion between the locked state and the unlocked state, resulting in a small range of variation of the applicable bottle cap diameter. For example, the applicable bottle cap diameter is about 28mm to 32mm, and the range of variation of the bottle cap diameter can only be about 3mm to 4mm. The bottle protection cover with a translational clamp arm cannot be installed by the operator on the bottle to be protected in the locked state, which is very inconvenient in actual use. At the same time, the technicians in this field cannot expand the range of variation of the applicable locked bottle cap diameter and the bottleneck length by adding translational clamp arms of different lengths. The bottle protection cap with a single clamp arm is difficult to achieve a locking effect for various combinations of bottles with shorter and longer necks, and bottles with large and small cap diameters. In summary, the application of the bottle protection cap with a translational clamp arm in the prior art is relatively limited, and cannot meet the protection needs of a large number of bottles of different sizes on the market. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 5 The embodiment of the present invention provides a bottle protection cover, comprising a shell 1 and a locking assembly arranged in the shell 1; a receiving cavity 15 for inserting a bottleneck is arranged in the shell 1, and the locking assembly comprises at least two rotating arm mechanisms, and a convex tooth portion 13 is arranged at one end of each rotating arm mechanism close to the receiving cavity 15, and the rotating arm mechanism clamps the annular protrusion of the bottle mouth, the annular recessed portion of the bottle mouth or the bottleneck inserted into the receiving cavity 15 through the convex tooth portion 13, so that the bottle protection cover is in a locked state and the bottle mouth inserted into the receiving cavity 15 cannot be pulled out of the receiving cavity 15; when the bottle protection cover is in the locked state and the bottleneck has not yet been inserted into the receiving cavity 15, the straight-line distance from the convex tooth portion 13 on each rotating arm mechanism to the inner side surface of the opposite receiving cavity is different.

[0041] It is worth noting that the working principle of this embodiment is as follows: when a bottle needs to be protected, the bottle neck is inserted into the accommodating cavity 15 in the housing 1. During the insertion process, the rotating clamp arm mechanism in the housing 1 is subjected to the thrust of the bottle insertion and rotates in the direction away from the accommodating cavity 15, so that the space of the accommodating cavity 15 becomes larger, ensuring that the bottle neck can be smoothly inserted into the accommodating cavity 15. When the bottle mouth reaches or exceeds the limit height of the convex tooth portion 13, there is no need to use the bottle to apply thrust to the rotating clamp arm mechanism. At this time, the rotating clamp arm mechanism rotates in the direction close to the accommodating cavity 15, so that the space of the accommodating cavity 15 becomes smaller, until the convex tooth portion 13 on the rotating clamp arm mechanism clamps the annular protrusion or annular recess at the end of the bottle mouth, thereby locking the bottle. The embodiment of the present invention allows the operator to install the protective cover in the locked state with one hand, which greatly improves the convenience of use.

[0042] In order to expand the applicable range of bottle cap diameters, the present embodiment provides at least two rotating arm mechanisms, and defines that when the bottle protection cover is in a locked state and no bottle neck has been inserted into the accommodating cavity 15, the linear distances from the convex tooth portion 13 on each rotating arm mechanism to the inner surface of the corresponding accommodating cavity are different. Figure 2As shown in , each rotating arm mechanism can lock bottles with different cap diameters and different bottleneck lengths. It is worth noting that when the bottle protection cover is in the locked state and no bottleneck has been inserted into the accommodating cavity 15, that is, the arms in each rotating arm mechanism are in the initial setting position in a static state, at this time, the linear distance from the convex tooth portion 13 on each rotating arm mechanism to the inner side surface of the corresponding accommodating cavity is different.

[0043] As a preferred embodiment, the locking assembly includes a first rotating arm mechanism and a second rotating arm mechanism; the first rotating arm mechanism is arranged above the second rotating arm mechanism, the arm length of the first rotating arm mechanism is greater than the arm length of the second rotating arm mechanism, and a pin shaft 6 penetrating through the opposite side surfaces of the shell 1 is provided on one side near the bottom of the shell 1, and the first rotating arm mechanism and the second rotating arm mechanism are both connected to the pin shaft 6, so that the first rotating arm mechanism and the second rotating arm mechanism rotate around the pin shaft 6 to realize the conversion of the locked state and the unlocked state of the bottle protective cover.

[0044] Specifically, the locking assembly in the present embodiment is further defined as including a first rotating arm mechanism and a second rotating arm mechanism, and the first rotating arm mechanism is arranged above the second rotating arm mechanism, and the arm length of the first rotating arm mechanism is greater than the arm length of the second rotating arm mechanism, so that the first rotating arm mechanism is mainly used to lock bottles with normal bottleneck length or longer bottlenecks, and the second rotating arm mechanism is mainly used to lock bottles with shorter bottlenecks. It can be understood that when a bottle with normal bottleneck length or longer bottleneck is inserted into the accommodating cavity 15, the first rotating arm mechanism clamps the annular protrusion or annular recessed portion at the end of the bottle mouth through its convex tooth portion 13, and the second rotating arm mechanism clamps the bottleneck through its convex tooth portion 13, such as Figure 3 When a bottle with a shorter neck is inserted into the accommodating cavity 15, the mouth of the bottle may not reach the locking height of the first rotating arm mechanism, so the second rotating arm mechanism at the bottom clamps the annular protrusion or annular recess at the end of the mouth of the bottle through its convex tooth portion 13, as shown in FIG. Figure 4 It is worth noting that the measurement definition diagram of the bottle cap diameter and the bottle neck length in this embodiment is as shown in FIG. Figure 5 shown.

[0045] As a preferred solution, the first rotating arm mechanism includes a first arm 2 and a first spring 4, and the second rotating arm mechanism includes a second arm 3 and a second spring 5; one end of the first arm 2 and the second arm 3 are both provided with an assembly hole for the pin 6 to pass through;

[0046] A protrusion 14 is provided on one side of the housing 1 away from the accommodating cavity 15, one end of the first spring 4 is connected to the protrusion 14, and the other end of the first spring 4 is connected to the first clamping arm 2, and the first clamping arm 2 is pulled by the first spring 4 to tilt from bottom to top;

[0047] One end of the second spring 5 is connected to the protruding portion 14 , and the other end of the second spring 5 is connected to the second clamping arm 3 . The second clamping arm 3 is pulled by the second spring 5 to tilt from bottom to top.

[0048] Specifically, the present embodiment utilizes a combination of springs and clamping arms to achieve locking of the bottle in the accommodating cavity 15. First, one end of each of the first clamping arm 2 and the second clamping arm 3 is provided with an assembly hole for the pin 6 to penetrate, so that the first clamping arm 2 and the second clamping arm 3 are both arranged on the pin 6, and the two can coaxially rotate around the pin 6. Further, by providing the first spring 4 and the second spring 5, it can be understood that the first spring 4 and the second spring 5 are arranged to be inclined from top to bottom, so that the first clamping arm 2 and the second clamping arm 3 are respectively pulled by the first spring 4 and the second spring 5 and tilted from bottom to top, so as to facilitate the insertion space of the accommodating cavity 15 to be opened when the bottleneck is inserted into the accommodating cavity 15. In the process of locking the inserted bottleneck, the clamping arm is squeezed by the bottleneck, so that the spring connected to the clamping arm is compressed. At this time, the spring applies a reverse force to the clamping arm for restoring elastic deformation, thereby driving the clamping arm to squeeze in the direction of the bottleneck, thereby achieving the limit of the bottleneck.

[0049] As a preferred solution, the length of the first clamp arm 2 is 49 mm to 59 mm, and the length of the second clamp arm 3 is 36 mm to 48 mm.

[0050] As a preferred embodiment, when the bottle protection cover is in the locked state and the bottleneck has not yet been inserted into the accommodating cavity 15, the straight-line distance from the convex tooth portion 13 on the first clamping arm 2 to the inner surface of the corresponding accommodating cavity is 11 mm to 25 mm, and the straight-line distance from the convex tooth portion 13 on the second clamping arm 3 to the inner surface of the corresponding accommodating cavity is 21 mm to 29 mm.

[0051] As a preferred embodiment, when the first clamp arm 2 connected to the first spring 4 is subjected to a radial compression of 5mm to 15mm from a zero force state along a direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the first spring 4 is 8.3N to 47.6N; when the second clamp arm 3 connected to the second spring 5 is subjected to a radial compression of 5mm to 15mm from a zero force state along a direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the second spring 5 is 15.7N to 43.5N.

[0052] Specifically, in one embodiment of the present invention, the size and radial locking force range of the first clamp arm 2 and the second clamp arm 3 are further limited, and within this limited range, the protection size range of different bottle cap diameters and bottlenecks can be greatly expanded, which provides great convenience for shopping malls to uniformly purchase a protective cover. Specifically, within this limited range, in one embodiment of the present invention, at least bottles with a bottle cap diameter of 26.4mm to 40.3mm and a bottleneck length of 25mm to 132mm can be locked, and the bottle cap diameter variation range reaches 14.9mm. In another embodiment of the present invention, at least bottles with a bottle cap diameter of 19.8mm to 38.5mm and a bottleneck length of 24mm to 116mm can be locked, and the bottle cap diameter variation range reaches 18.7mm. For bottles with a bottleneck length greater than 116mm, the locking effect can also be ensured.

[0053] Furthermore, the partial pressure perpendicular to the bottleneck generated by the first spring 4 and the second spring 5 at the convex tooth portion 13 of the corresponding clamp arm, i.e., the radial locking force, can be measured by a pressure sensor. Specific data are as follows: as shown in the following embodiments 1 to 20, when the first clamp arm 2 connected with the first spring 4 is from zero force state to radial compression of 5mm, 10mm, and 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the first spring 4 is 8.3N, 17.7N, and 22.1N respectively; when the second clamp arm 3 connected with the second spring 5 is from zero force state to radial compression of 5mm, 10mm, and 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the second spring 5 is 15.7N, 24.7N, and 35.2N. As shown in the following embodiment 23, when the first clamp arm 2 connected to the first spring 4 is subjected to radial compression of 5mm, 10mm, and 15mm from zero force state along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the first spring 4 is 21.7N, 32.5N, and 47.6N respectively; when the second clamp arm 3 connected to the second spring 5 is subjected to radial compression of 5mm, 10mm, and 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the second spring 5 is 18.7N, 29.0N, and 43.5N. It can be seen that the shorter the clamp arm, the greater the required radial locking force. Too large a radial locking force makes it inconvenient for the operator to install the bottle protective cover, and too small a radial locking force cannot prevent the bottleneck from being forcibly pulled out. The inventor of the embodiment of the present invention has concluded in the experiment that even if there is a good locking structure design, if a certain radial locking force is not achieved, no matter how good the structure is, it cannot play a locking role.

[0054] As a preferred solution, the thickness of the convex tooth portion 13 is 0.3 mm to 2.9 mm.

[0055] Specifically, the present embodiment further defines that the convex tooth portion 13 is a thin tooth portion with a thickness of 0.3 mm to 2.9 mm. For example, the thickness of the convex tooth portion 13 is 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 2.0 mm, 2.2 mm, 2.6 mm, 2.9 mm, etc., which is not specifically defined in the present embodiment. Under the condition of sufficient strength, the thin protruding teeth with smaller thickness can more effectively and stably clamp the annular protrusion or annular recess on the end of the bottle neck. The clamping arm without the convex tooth portion 13 or with the convex tooth portion 13 being too thick is not easy to clamp into the annular recess at the end of the bottle mouth, resulting in unstable locking.

[0056] As a preferred embodiment, the locking assembly also includes a rotating buckle mechanism; the rotating buckle mechanism is arranged below the second rotating buckle arm mechanism, one end of the rotating buckle mechanism is connected to the pin shaft 6, and the rotating buckle mechanism is used to tighten the bottleneck inserted into the accommodating cavity 15.

[0057] Specifically, the locking assembly in this embodiment further includes a rotating buckle mechanism, so that the operator can install the protective cover with one hand when the protective cover is in the locked state. In the process of locking the inserted bottleneck, the rotating buckle mechanism can rotate in the direction close to the accommodating cavity 15, so that the space of the accommodating cavity 15 becomes smaller, until the rotating buckle 7 clamps the bottleneck to achieve lateral compression and limiting. Figure 3 and Figure 4 As shown, the resistance to preventing the bottleneck from swinging freely in the accommodating chamber 15 is increased, the locking effect on the bottleneck is enhanced and the anti-poking effect is provided at the same time.

[0058] As a preferred embodiment, the rotating buckle mechanism includes a rotating buckle 7 and a torsion spring 8; the torsion spring 8 is wound around the pin shaft 6, and one end of the rotating buckle 7 is provided with an assembly hole for the pin shaft 6 to pass through, and the rotating buckle 7 is subjected to the torque applied by the torsion spring 8 to rotate laterally in the direction close to the accommodating cavity 15, so as to achieve a radial compression effect on the bottleneck and at the same time have an anti-poking effect.

[0059] Specifically, the rotating latch mechanism in this embodiment further includes a rotating latch 7 and a torsion spring 8. It can be understood that the torsion spring 8 is wound around the pin shaft 6, one end of which can extend to the side surface of the shell 1 away from the accommodating cavity 15 for combination, and the other end is connected to the rotating latch 7. During the locking process of the inserted bottleneck, due to the torsion action of the torsion spring 8, it will apply a torque to the rotating latch 7, thereby driving the rotating latch 7 to rotate in the direction close to the accommodating cavity 15, so that the space of the accommodating cavity 15 becomes smaller until the rotating latch 7 clamps the bottleneck to achieve lateral compression limiting.

[0060] As a preferred solution, an arc-shaped groove is provided at one end of the rotating latch 7 close to the accommodating cavity 15 .

[0061] Specifically, this embodiment takes into account that the bottleneck surface of most bottle products is arc-shaped, and therefore an arc-shaped groove is provided at one end of the rotating clip 7 close to the accommodating cavity 15 to fit the contour of the bottleneck of the bottle product. This can increase the contact area between the rotating clip 7 and the bottleneck, thereby better clamping the bottleneck in the accommodating cavity 15 and avoiding damage to the surface of the bottleneck.

[0062] As a preferred solution, an electronic tag is provided in the housing 1 .

[0063] Specifically, in order to prevent bottled goods from being stolen, this embodiment also provides an electronic tag inside the outer shell 1 of the protective cover. Currently, most shopping malls are equipped with anti-theft detection devices with electronic tags at the entrances and exits. When a thief attempts to take the bottled goods equipped with the protective cover of this embodiment out of the mall, the anti-theft detection device can detect the electronic tag inside the protective cover and sound an alarm, thereby playing an anti-theft protection role.

[0064] As a preferred solution, a protruding block is provided on the inner surface of the housing 1, the protruding block has a mounting cavity for assembling the electronic tag, and the protruding height of the protruding block is greater than 3 mm.

[0065] It is worth noting that, considering that the electronic tags currently installed for bottle products on the market are usually ferrite coils or capacitor anti-theft parts, such electronic tags are easily shielded by metal interference. When metal (such as coins, keys, etc.) is close, the alarm performance will be greatly damaged or even fail. In order to prevent the external metal parts from being too close to the electronic tags in the shell 1, this embodiment is provided with two rows of raised blocks on the opposite side surfaces of the shell 1. The raised blocks have installation cavities for the electronic tags to be assembled, and can also ensure that the electronic tags are more firmly arranged inside the shell 1. Preferably, the raised height of the above-mentioned raised blocks is greater than 3 mm to better prevent the external metal parts from being too close to the electronic tags in the shell 1.

[0066] As a preferred solution, the electronic tag is an acoustic-magnetic anti-theft tag, a radio frequency anti-theft tag or an RFID tag.

[0067] Specifically, it has been mentioned above that the ferrite coils and capacitor anti-theft parts commonly used in bottle products on the market are easily shielded by metal interference. In order to avoid the failure of the alarm performance due to the influence of external metal, the electronic tag in this embodiment is specifically an acoustic magnetic anti-theft tag or a radio frequency anti-theft tag. Preferably, when the electronic tag is an acoustic magnetic anti-theft tag, a permanent magnetic resonance sheet acoustic magnetic anti-theft tag is further used, so that the electronic tag has a good anti-metal shielding effect, and at the same time will not destroy the alarm performance after contact with a strong magnetic field.

[0068] In addition, an RFID tag is used as an electronic tag installed in the housing, which can be used for product traceability or inventory management.

[0069] As a preferred embodiment, the housing 1 includes a transparent cover 101 and a side cover 102; the transparent cover 101 and the side cover 102 are provided with assembly holes on the opposite side surfaces close to the bottom for the pin 6 to pass through, so that the transparent cover 101 and the side cover 102 are rotatably connected through the pin 6, and the transparent cover 101 and the side cover 102 are opened and closed around the pin 6, the transparent cover 101 is provided with the accommodating cavity 15, and the side cover 102 is provided with the locking assembly.

[0070] Specifically, considering that some bottle products on the market, such as high-end bottled wine, etc., will have their packaging bottles designed to be more gorgeous to attract customers to buy, in order to avoid blocking the appearance of bottle products, the shell 1 in this embodiment is composed of a transparent cover 101 and a side cover 102, and the accommodating cavity 15 for inserting the bottleneck is arranged in the transparent cover 101. In addition, the cover body for inserting the bottleneck is set to be transparent, which helps the commodity manager to check the appearance damage and locking status of the bottle products. Further, in this embodiment, the transparent cover 101 and the side cover 102 are connected by a pin 6, so that the two can be rotated around the pin 6 to realize opening and closing, which is convenient for unlocking the bottle in the locked state.

[0071] It is worth noting that, although the transparent cover 101 and the side cover 102 in this embodiment can be opened and closed, when the bottle needs to be locked, there is no need to open the transparent cover 101 and the side cover 102. Based on the working principle of the protective cover introduced in this embodiment, the bottle to be locked can be directly inserted into the accommodating cavity 15 in the shell 1. When there are many bottle products to be locked, there is no need to frequently open the transparent cover 101 and the side cover 102, which greatly improves the convenience and efficiency of installing the protective cover.

[0072] As an optional embodiment, the transparent cover 101 and the side cover 102 in this embodiment may be provided with the above-mentioned electronic tags.

[0073] As a preferred solution, the bottle protection cover further comprises a locking mechanism, and the locking mechanism locks the transparent cover 101 and the side cover 102 when the transparent cover 101 and the side cover 102 are closed.

[0074] Specifically, in order to prevent the transparent cover 101 and the side cover 102 from opening by themselves or being forcibly opened during the locking process of the inserted bottleneck, thereby preventing the protection of the bottle from becoming ineffective, the present embodiment provides a locking mechanism to lock the transparent cover 101 and the side cover 102 when they are closed. If the transparent cover 101 and the side cover 102 are to be opened, the locking mechanism needs to be unlocked first, which further improves the anti-destruction and anti-theft performance for the bottle.

[0075] As a preferred solution, the locking mechanism includes an ejector pin 9 and a lock core 10; a bracket for fixing the ejector pin 9 is provided on one side surface of the transparent cover 101, and the lock core 10 is provided on one side surface of the side cover 102 away from the accommodating cavity 15;

[0076] The lock core 10 includes a lock core spring, a lock core bead seat attracted by a magnet, a plurality of (such as 3) round steel balls, a cover body and a lock core shell 1 arranged on the outside of the cover body. When the ejector pin 9 is inserted into the lock core 10, the lock core bead seat is pushed forward by the lock core spring, so that the plurality of round steel balls are squeezed by the cover body to lock the ejector pin 9.

[0077] Further preferably, when the lock core bead seat is attracted by magnetic force, the lock core 10 is converted into an unlocked state, so that the bottle inserted into the accommodating cavity 15 can be pulled out from the accommodating cavity 15 .

[0078] Specifically, the locking mechanism in this embodiment is composed of a thimble 9 and a lock core 10. It is understandable that when the housing 1 needs to be locked, the transparent cover 101 and the side cover 102 are closed, and in this process, the thimble 9 in the transparent cover 101 is inserted into the lock core 10 provided on the side cover 102. In the process of inserting the thimble 9 into the lock core 10, the lock core bead seat is pushed forward by the lock core spring, so that the multiple round steel balls are squeezed by the cover body and lock the thimble 9, so that the thimble 9 cannot be pulled out. When the locking mechanism needs to be unlocked, since the iron core bead seat contains a ferromagnetic block, it is necessary to use a magnet to attract the iron core bead seat to resist the front force of the iron core spring, so that the multiple round steel balls are loosened and can no longer lock the thimble 9, and the lock core 10 is converted into an unlocked state, and the thimble 9 can be withdrawn from the lock core 10 to achieve unlocking.

[0079] As a preferred solution, one end of the ejector pin 9 for inserting into the lock core 10 has a smooth surface.

[0080] Further preferably, one end of the ejector pin 9 for inserting into the lock core 10 is in a spherical crown shape or a flat surface shape.

[0081] It is worth noting that the common thimbles on the market are all pointed thimbles, which are used to pierce soft products to be protected (such as clothes, towels, etc.) to lock them. However, the protective cover in this embodiment is mainly used to protect bottle products. It is preferred not to use the pointed thimble in the prior art. By limiting the end of the thimble 9 for inserting the lock core 10 to a smooth surface, preferably in a spherical crown shape or a flat surface, it can prevent the operator who installs the protective cover from being stabbed, thereby improving the safety of product use.

[0082] As a preferred solution, a baffle member 11 is provided on a surface of one side of the side cover 102 away from the accommodating cavity 15 , and the baffle member 11 is disposed above the lock core 10 .

[0083] It is worth noting that in order to further improve the locking accuracy and ensure that the ejector pin 9 located in the transparent cover 101 can be more accurately inserted into the lock core 10 located in the side cover 102, a baffle member 11 can be optionally provided in the side cover 102 in this embodiment, and the baffle member 11 is arranged above the lock core 10, so that during the process of inserting the ejector pin 9 into the lock core 10, the insertion direction of the ejector pin 9 can be restricted to a certain extent, thereby ensuring that the ejector pin 9 is smoothly inserted into the lock core 10.

[0084] As a preferred solution, an arc-shaped stopper 12 is provided on the inner surface of the transparent cover 101 .

[0085] Specifically, in this embodiment, an arc-shaped stopper 12 is further provided on the inner surface of the transparent cover 101. It is understandable that, considering that the bottleneck surface of most bottle products is in an arc shape, the arc-shaped stopper 12 can be provided to fit the contour of the bottleneck of the bottle product, so that the contact area between the arc-shaped stopper 12 and the bottleneck can be increased, so that the bottleneck can be better limited, and damage to the appearance of the bottleneck can be avoided. In the process of locking the inserted bottleneck, the arc-shaped stopper 12 can limit the inserted bottleneck together with the locking assembly, thereby increasing the resistance to prevent the bottleneck from swinging freely in the accommodating cavity 15, and enhancing the locking effect on the bottleneck.

[0086] As a preferred solution, at least one component of the bottle protection cover is made of a recycled plastic.

[0087] Further preferably, the cover body forming the accommodating cavity is made of recycled PC.

[0088] Further preferably, the clamping arm in each of the rotating clamping arm mechanisms is made of recycled ABS.

[0089] In this embodiment, in order to comply with the concept of environmental protection, at least one component in the bottle protection cover is made of a recycled plastic. It is understandable that the components in the bottle protection cover are the various components that constitute the bottle protection cover, such as the shell, the clamp arm, the rotating clamp, etc., and this embodiment will not be described in detail here.

[0090] The bottle protection cover provided by the embodiment of the present invention is provided with at least two rotating arm mechanisms in the housing 1, and when the bottle protection cover is in a locked state and no bottleneck has been inserted into the accommodating cavity, the linear distances from the convex teeth on each rotating arm mechanism to the inner surface of the relative accommodating cavity are different, and one of the rotating arm mechanisms can always find a suitable locking position for bottles of different sizes, thereby effectively expanding the range of variation of applicable bottle cap diameters and bottleneck lengths, and providing great convenience for commodity managers to uniformly purchase a protection cover. In addition, by providing a convex tooth portion 13 at one end of the rotating arm mechanism close to the accommodating cavity 15, the annular protrusions or annular recesses of various bottles can be stably and reliably clamped, thereby ensuring that the smooth bottle can be reliably clamped in the accommodating cavity 15.

[0091] Specifically, in one embodiment of the present invention, at least bottles with a cap diameter of 26.4mm to 40.3mm and a bottleneck length of 25mm to 132mm can be locked, and the range of the cap diameter variation reaches 14.9mm. In another embodiment of the present invention, at least bottles with a cap diameter of 19.8mm to 38.5mm and a bottleneck length of 24mm to 116mm can be locked, and the range of the cap diameter variation reaches 18.7mm. The range of the cap diameter variation is significantly increased from about 3mm to 4mm corresponding to the bottle protective cover with a translational clamp arm in the prior art to about 18mm to 19mm, and the locking effect can also be ensured for bottles with a bottleneck length greater than 116mm. At the same time, the embodiment of the present invention allows the operator to install the protective cover in a locked state with one hand, which greatly improves the user experience of the product.

[0092] In order to demonstrate that the embodiments of the present invention can effectively expand the applicable range of bottle cap diameters, several embodiments are described below (the following embodiments all use the same locking mechanism, that is, they all include a push pin 9 and a lock core 10, and may contain or contain an acoustic-magnetic anti-theft alarm, a radio frequency anti-theft alarm or an RFID tag).

[0150] Embodiment 20

[0151] The bottle protection cover used in this embodiment includes a first rotating arm mechanism, a second rotating arm mechanism and a rotating buckle mechanism.

[0153] Example 21 (Proving the importance of the protruding tooth portion 13 at the front end of the clamp arm)

[0154] The bottle protective cover used in this embodiment also includes a first rotating arm mechanism, a second rotating arm mechanism and a rotating buckle mechanism. The length of the arm of the first rotating arm mechanism is 56.9 mm, and the length of the arm of the second rotating arm mechanism is 46.4 mm. However, the ends of the first rotating arm mechanism and the second rotating arm mechanism are both at a single angle, approximately 85° to 95°, and do not have a convex tooth portion 13. The bottle protective cover was used to perform a locking test on the corresponding bottles in Examples 1 to 20, and it was found that the bottles in Examples 6, 12, and 17 could not be locked, that is, the protective cover without the convex tooth portion 13 at the front end of the arm can still pull out the bottle in the accommodating cavity 15 by hand when in the locked state.

[0155] Example 22 (Proving the importance of spring strength to the stability of bottle mouth locking in the same locking structure)

[0156] The bottle protection cover used in this embodiment also includes a first rotating arm mechanism, a second rotating arm mechanism and a rotating buckle mechanism. The arm length of the first rotating arm mechanism is 56.9mm, and the arm length of the second rotating arm mechanism is 46.4mm. The ends of the first rotating arm mechanism and the second rotating arm mechanism are both provided with a convex tooth portion 13, and the thickness of the convex tooth is 1.5mm. However, the two springs have a relatively low strength. When the first arm 2 connected with the first spring 4 is from zero force state to radial compression of 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the first spring 4 is 3.3N; when the second arm 3 connected with the second spring 5 is from zero force state to radial compression of 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the second spring 5 is 2.9N. The corresponding bottles in Examples 1 to 20 were locked using the bottle protection cover, and it was found that the bottle could be pulled out of the accommodating cavity 15 by hand. That is, when the bottle protection cover with a weaker spring strength in this embodiment is in a locked state, although it has a good locking structure, the bottle in the accommodating cavity 15 can still be pulled out by hand.

[0157] Example 23 (Changing the length of the clamp arm and increasing the strength of the spring can be applied to larger bottle mouth sizes)

[0158] The bottle protection cover used in this embodiment includes a first rotating arm mechanism, a second rotating arm mechanism and a rotating buckle mechanism. The arm length of the first rotating arm mechanism is 51.4mm, and the arm length of the second rotating arm mechanism is 28.4mm. The ends of the first rotating arm mechanism and the second rotating arm mechanism are both provided with a convex tooth portion 13, and the thickness of the convex tooth is 1.5mm. When the first arm 2 connected with the first spring 4 is from zero force state to radial compression of 5mm, 10mm, and 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the first spring 4 is 21.7N, 32.5N, and 47.6N respectively; when the second arm 3 connected with the second spring 5 is from zero force state to radial compression of 5mm, 10mm, and 15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force applied by the second spring 5 is 18.7N, 29.0N, and 43.5N. When the bottle protective cover is in the locked state and the bottleneck has not yet been inserted into the accommodating cavity 15, the straight-line distance from the convex tooth portion 13 on the first clamping arm 2 to the inner surface of the corresponding accommodating cavity is 23 mm, and the straight-line distance from the convex tooth portion 13 on the second clamping arm 3 to the inner surface of the corresponding accommodating cavity is 25 mm.

[0159] Specifically, after the bottle protection cap of Example 23 was used to perform a locking test on bottles with a larger bottle mouth size, the test results are listed in Table 1.

[0160] Table 1 Locking test bottles and their locking test results

[0161] Bottle cap diameter (mm) Bottle neck length (mm) The first rotating arm mechanism is locked The second rotating arm mechanism is locked 29.7 45 √ 31.2 21 √ 28.0 20 √ 26.4 72 √ 27.9 132 √ 36.5 28 √ 38.2 38 √ 40.3 25 √ 31.9 40 √ 31.4 65 √

[0162] It can be seen from Table 1 that, for bottles with a bottle cap diameter of 26.4 mm to 40.3 mm, the convex tooth portion 13 of the first rotating arm mechanism or the second rotating arm mechanism can smoothly clamp the annular protrusion or the annular recess at the end of the bottle mouth, and the bottle cannot be pulled out after being clamped. However, when a magnetic force is applied to the outside of the lock core 10, the lock core 10 can be opened so that the bottle can be pulled out of the accommodating cavity 15.

[0163] From the above-listed embodiments, it can be seen that the bottle caps provided in embodiments 1 to 20 are applicable to bottle caps with a diameter of at least 19.8 mm to 38.5 mm, and the range of bottle cap diameter variation is as high as 18.7 mm; the bottle caps provided in embodiment 23 are applicable to bottle caps with a diameter of at least 26.4 mm to 40.3 mm, that is, they are also applicable to bottles with a bottle cap diameter greater than 38.5 mm. Compared with the bottle caps in the prior art, the applicable bottle cap diameter variation range is greatly improved, and the protection needs of a large number of bottle products of different sizes on the market can be well met.

[0164] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made (for example, using other magnetic unlocking mechanisms other than lock cores, or using unlocking mechanisms made of shape memory alloy components, or using pointed ejector pins, or omitting ejector pin guide structures, or selecting a lock core unlocking strength of 4000-12000Gs, or using two or more rotating clamping arm mechanisms but changing their lengths, changing the specific sizes and shapes of the convex teeth at the front ends of the multiple clamping arms in the present invention, changing the manufacturing materials of the various components in the protective cover, using translational rather than rotational clamping parts to achieve the same radial compression bottleneck and anti-stabbing effects, different types and quantities of springs and EAS alarms or RFID tags, and different installation methods, and Figure 1 Different appearances but equivalent internal structures, changing the size and shape of the accommodating cavity, increasing, reducing or canceling the preset limiting structure on the inner surface of the transparent cover, or changing the transparent cover to be partially or completely opaque, which are not listed here one by one), these improvements and modifications are also considered to be equivalent to the protection scope of the present invention.
