Description

TECHNICAL FIELD

[0001] The utility model relates to bottle commodity protection technical field, especially a bottle protection cover. BACKGROUND

[0002] With the extensive popularization of the market, the consumption of bottle commodities such as bottled wine is increasing, and the situation of stealing by breaking the seal cap is also increasing. In order to effectively protect the bottle commodities, the prior art provides a bottle protection cover with a clamping arm. When the mouth of the bottle commodity is inserted into the bottle protection cover (accommodation cavity), the clamping arm can limit the mouth, thereby preventing the cap from being broken. However, the clamping arm of the prior art bottle protection cover is usually translated in a certain direction to realize the conversion between the locked state and the unlocked state, which limits the range of the diameters of the caps that can be applied. For example, the diameter of the cap that can be applied is about 28 mm to 32 mm, and the range of the diameter of the cap is only about 3 mm to 4 mm. The bottle protection cover with the translation type clamping arm cannot be installed on the bottle to be protected by the operator when it is in the locked state, which is not convenient in actual use. Meanwhile, the technical personnel in the field cannot expand the range of the diameters of the caps that can be applied and the lengths of the necks by increasing clamping arms of different lengths. The bottle protection cover with a single clamping arm cannot realize the locking effect for various combinations of short necks, long necks, large cap diameters, and small cap diameters. In summary, the bottle protection cover with the translation type clamping arm of the prior art has large application limitations and cannot meet the protection requirements of a large number of bottle commodities of different sizes on the market.

DETAILED DESCRIPTION

[0039] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0040] Please refer to Figures 1 to 5 The present embodiment provides a bottle protection cover, which comprises a shell 1 and a locking assembly arranged in the shell 1; the shell 1 is provided with a receiving cavity 15 for inserting a bottle neck, and the locking assembly comprises at least two rotating clamping arm mechanisms, and each rotating clamping arm mechanism is provided with a protruding tooth portion 13 at one end close to the receiving cavity 15; the rotating clamping arm mechanism clamps the annular protruding portion, the annular recessed portion of the bottle mouth or the bottle neck inserted into the receiving cavity 15 through the protruding 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 bottle neck has not been inserted into the receiving cavity 15, the straight-line distance from the protruding tooth portion 13 on each rotating clamping arm mechanism to the opposite inner side surface of the receiving cavity is different.

[0041] It is worth noting that the working principle of the present embodiment is as follows: when a certain bottle needs to be protected, the bottle neck of the bottle is inserted into the receiving cavity 15 in the shell 1; during the insertion process, the rotating clamping arm mechanism in the shell 1 will be pushed away from the receiving cavity 15 by the pushing force of the bottle insertion, so that the space of the receiving cavity 15 becomes larger, ensuring that the bottle neck can be smoothly inserted into the receiving cavity 15; when the bottle mouth reaches or exceeds the limiting height of the protruding tooth portion 13, it is not necessary to apply a pushing force to the rotating clamping arm mechanism by the bottle; at this time, the rotating clamping arm mechanism rotates towards the receiving cavity 15, so that the space of the receiving cavity 15 becomes smaller, until the protruding tooth portion 13 on the rotating clamping arm mechanism clamps the annular protruding portion or the annular recessed portion at the end of the bottle mouth, thereby achieving the locking of the bottle. The present embodiment enables the operator to also operate with one hand to install the protection cover in the locked state, greatly improving the use convenience.

[0042] In order to expand the applicable range of the diameter change of the bottle cap, at least two rotating clamping arm mechanisms are arranged in the present embodiment, and when the bottle protection cover is in the locked state and the bottle neck has not been inserted into the receiving cavity 15, the straight-line distance from the protruding tooth portion 13 on each rotating clamping arm mechanism to the opposite inner side surface of the receiving cavity is different. The straight-line distance is, for example, Figure 2As shown in the figure, so that each rotating clamping arm mechanism can lock bottles with different cap diameters and different neck lengths. It is worth mentioning that when the bottle protection cover is in the locked state and the bottle neck has not been inserted into the accommodation cavity 15, the clamping arm in each rotating clamping arm mechanism is in the initial setting position in the static state, at this time the straight line distance between the protruding tooth part 13 on each rotating clamping arm mechanism and the opposite inner side surface of the accommodation cavity is not the same.

[0043] As a preferred solution, the locking assembly includes a first rotating clamping arm mechanism and a second rotating clamping arm mechanism; the first rotating clamping arm mechanism is arranged above the second rotating clamping arm mechanism, the length of the clamping arm of the first rotating clamping arm mechanism is greater than the length of the clamping arm of the second rotating clamping arm mechanism, and a pin shaft 6 is arranged in the shell 1 near one side of the bottom, and the first rotating clamping arm mechanism and the second rotating clamping arm mechanism are connected to the pin shaft 6, so that the first rotating clamping arm mechanism and the second rotating clamping arm mechanism rotate around the pin shaft 6 to realize the conversion between the locked state and the unlocked state of the bottle protection cover.

[0044] Specifically, the locking assembly in the embodiment further includes a first rotating clamping arm mechanism and a second rotating clamping arm mechanism, and the first rotating clamping arm mechanism is arranged above the second rotating clamping arm mechanism, and the length of the clamping arm of the first rotating clamping arm mechanism is greater than the length of the clamping arm of the second rotating clamping arm mechanism, so that the first rotating clamping arm mechanism is mainly used for locking bottles with normal neck length or longer neck, and the second rotating clamping arm mechanism is mainly used for locking bottles with shorter neck. It can be understood that when a bottle with normal neck length or longer neck is inserted into the accommodation cavity 15, the first rotating clamping arm mechanism clamps the annular protruding part or annular recessed part at the mouth end of the bottle through the protruding tooth part 13 thereof, and the second rotating clamping arm mechanism clamps the neck of the bottle through the protruding tooth part 13 thereof, as shown in the figure. Figure 3 When a bottle with shorter neck is inserted into the accommodation cavity 15, the mouth of the bottle can not reach the locking height of the first rotating clamping arm mechanism, so the second rotating clamping arm mechanism below clamps the annular protruding part or annular recessed part at the mouth end of the bottle through the protruding tooth part 13 thereof, as shown in the figure. Figure 4 It is worth mentioning that the measurement definition diagram of the bottle cap diameter and the neck length in the embodiment is as shown in the figure. Figure 5

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

[0046] ​The outer shell 1 is provided with a protrusion 14 on the side surface away from the accommodating cavity 15, one end of the first spring 4 is connected with the protrusion 14, the other end of the first spring 4 is connected with the first clamping arm 2, and the first clamping arm 2 is inclined from bottom to top under the traction of the first spring 4;

[0047] One end of the second spring 5 is connected with the protrusion 14, and the other end of the second spring 5 is connected with the second clamping arm 3, and the second clamping arm 3 is inclined from bottom to top under the traction of the second spring 5.

[0048] Specifically, the present embodiment realizes the locking of the bottle in the accommodating cavity 15 by the combination of the spring and the clamping arm. Firstly, the first clamping arm 2 and the second clamping arm 3 are both provided with an assembly hole for the pin shaft 6 to pass through, so that the first clamping arm 2 and the second clamping arm 3 are both arranged on the pin shaft 6 and can rotate coaxially around the pin shaft 6. Further, by arranging 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 inclined from bottom to top under the traction of the first spring 4 and the second spring 5, which facilitates the opening of the insertion space of the accommodating cavity 15 when the bottle neck is inserted into the accommodating cavity 15, and in the process of locking the inserted bottle neck, the spring connected with the clamping arm is compressed due to the extrusion of the bottle neck, at this time the spring exerts a reverse force on the clamping arm for restoring the elastic deformation, thereby driving the clamping arm to extrude towards the direction of the bottle neck, realizing the limiting of the bottle neck.

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

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

[0051] As a preferred solution, when the first clamping arm 2 connected with the first spring 4 is vertically compressed by 5mm-15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the first spring 4 is 8.3N-47.6N; and when the second clamping arm 3 connected with the second spring 5 is vertically compressed by 5mm-15mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the second spring 5 is 15.7N-43.5N.

[0052] Specifically, in one embodiment of the present application, the size and radial locking force range of the first clamping arm 2 and the second clamping arm 3 are further limited, and within the limited range, the protection size range of different bottle cap diameters and bottle necks can be greatly expanded, which provides great convenience for the unified procurement of a protection cap in a supermarket. Specifically, within the limited range, in one embodiment of the present application, at least the bottle with a bottle cap diameter of 26.4mm-40.3mm and a bottle neck length of 25mm-132mm can be locked, and the change range of the bottle cap diameter reaches 14.9mm, and in another embodiment of the present application, at least the bottle with a bottle cap diameter of 19.8mm-38.5mm and a bottle neck length of 24mm-116mm can be locked, and the change range of the bottle cap diameter reaches 18.7mm, and the locking effect can also be ensured for the bottle with a bottle neck length greater than 116mm.

[0053] Further, the radial locking force of the first spring 4 and the second spring 5 mentioned above, which is perpendicular to the bottle neck, can be measured by a pressure sensor. Specifically, as shown in the following embodiments 1-20, when the first clamping arm 2 connected with the first spring 4 is vertically compressed by 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 of the first spring 4 is 8.3N, 17.7N and 22.1N respectively; when the second clamping arm 3 connected with the second spring 5 is vertically compressed by 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 of the second spring 5 is 15.7N, 24.7N and 35.2N respectively. As shown in the following embodiment 23, when the first clamping arm 2 connected with the first spring 4 is vertically compressed by 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 of the first spring 4 is 21.7N, 32.5N and 47.6N respectively; when the second clamping arm 3 connected with the second spring 5 is vertically compressed by 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 of the second spring 5 is 18.7N, 29.0N and 43.5N respectively. As can be seen, the shorter the clamping arm is, the greater the radial locking force required is. Too large radial locking force makes it inconvenient for the operator to install the bottle protection cap, and too small radial locking force cannot prevent the bottle neck from being pulled out forcibly. The inventor of the present application has obtained the following conclusion in experiments: even if there is a good locking structure design, if the determined radial locking force is not reached, the better structure cannot play a locking role.

[0054] As a preferred solution, the thickness of the protruding tooth part 13 is 0.3mm-2.9mm.

[0055] Specifically, the present embodiment further limits the convex tooth portion 13 to be a thin tooth portion with a thickness of 0.3mm-2.9mm, for example, the thickness of the convex tooth portion 13 is 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.1mm, 1.3mm, 1.5mm, 1.7mm, 2.0mm, 2.2mm, 2.6mm, 2.9mm, etc., which is not specifically limited herein. In the case of sufficient strength, the convex thin tooth with smaller thickness can more effectively and stably clamp the annular protruding portion or annular recessed portion on the neck end of the bottle mouth. The clamping arm without the convex tooth portion 13 or with the convex tooth portion 13 that is too thick is not easy to clamp into the annular recessed portion of the bottle mouth end, resulting in unstable locking.

[0056] As a preferred solution, the locking assembly further comprises a rotating clamping mechanism; the rotating clamping mechanism is arranged below the second rotating clamping arm mechanism, one end of the rotating clamping mechanism is connected to the pin shaft 6, and the rotating clamping mechanism is used to press the inserted bottle neck into the accommodating cavity 15.

[0057] Specifically, the locking assembly in the present embodiment further comprises a rotating clamping mechanism, so that the operator can also install it with one hand when the protective cover is in the locked state. In the process of locking the inserted bottle neck, the rotating clamping mechanism can be turned towards the accommodating cavity 15 to make the space of the accommodating cavity 15 smaller, until the rotating clamping member 7 clamps the bottle neck to achieve transverse compression limiting, as shown in Figure 3 and Figure 4 so as to increase the resistance to prevent the bottle neck from swinging randomly in the accommodating cavity 15, enhance the locking effect on the bottle neck, and at the same time have the effect of preventing being poked.

[0058] As a preferred solution, the rotating clamping mechanism comprises a rotating clamping member 7 and a torsional spring 8; the torsional spring 8 is arranged around the pin shaft 6, one end of the rotating clamping member 7 is provided with a fitting hole for the pin shaft 6 to pass through, and the rotating clamping member 7 is turned towards the accommodating cavity 15 by the torque applied by the torsional spring 8 to achieve radial compression of the bottle neck and at the same time have the effect of preventing being poked.

[0059] Specifically, the rotating clamping mechanism in the present embodiment further comprises a rotating clamping member 7 and a torsional spring 8. It can be understood that the torsional spring 8 is arranged around the pin shaft 6, one end of which can extend to the side surface away from the accommodating cavity 15 in the housing 1 for combination, and the other end is connected with the rotating clamping member 7. In the process of locking the inserted bottle neck, due to the torsional action of the torsional spring 8, it will apply torque to the rotating clamping member 7, thereby driving the rotating clamping member 7 to turn towards the accommodating cavity 15, so that the space of the accommodating cavity 15 becomes smaller, until the rotating clamping member 7 clamps the bottle neck to achieve transverse compression limiting.

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

[0061] Specifically, the embodiment takes into account that the bottle neck surface of most bottle products is arc-shaped, and therefore the rotating buckle 7 is provided with an arc-shaped groove at one end close to the accommodating cavity 15 to match the bottle neck contour of the bottle product, so as to increase the contact area between the rotating buckle 7 and the bottle neck, thereby better clamping the bottle neck in the accommodating cavity 15, while avoiding damage to the outer surface of the bottle neck.

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

[0063] Specifically, in order to prevent the bottle product from being stolen, the embodiment further provides an electronic tag in the shell 1 of the protective cover. At present, most shopping malls are equipped with electronic tag anti-theft detection devices at the entrances. When a thief attempts to take the bottle product provided with the protective cover of the embodiment out of the shopping mall, the anti-theft detection device can detect the electronic tag in the protective cover and alarm, thereby playing a role in anti-theft protection.

[0064] As a preferred solution, the inner side surface of the shell 1 is provided with a protruding block, 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 the electronic tags currently installed on bottle products on the market are usually ferrite coils or capacitive anti-theft devices. 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 disabled. In order to avoid the external metal part being too close to the electronic tag in the shell 1, the embodiment is provided with two rows of protruding blocks on the opposite side surfaces of the shell 1, the protruding blocks have mounting cavities for assembling the electronic tags, and at the same time, the electronic tags can be more stably arranged inside the shell 1. Preferably, the protruding height of the protruding block is greater than 3 mm, so as to better avoid the external metal part being too close to the electronic tag in the shell 1.

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

[0067] Specifically, as mentioned above, the ferrite coils and capacitive anti-theft devices commonly used for bottle products on the market are easily shielded by metal interference. In order to avoid the alarm performance being disabled due to external metal, the electronic tag in the embodiment is specifically an acousto-magnetic anti-theft tag or a radio frequency anti-theft tag. Preferably, when the electronic tag is an acousto-magnetic anti-theft tag, a permanent magnet resonance sheet acousto-magnetic anti-theft tag is further adopted, so that the electronic tag has good anti-metal shielding effect and will not damage the alarm performance after strong magnetic field contact.

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

[0069] As a preferred solution, the shell 1 comprises a transparent cover 101 and a side cover 102; opposite side surfaces of the transparent cover 101 and the side cover 102 near the bottom are provided with assembly holes for the pin shaft 6 to pass through, so that the transparent cover 101 and the side cover 102 are rotationally connected through the pin shaft 6, and the transparent cover 101 and the side cover 102 are opened and closed around the pin shaft 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, are designed to be more luxurious to attract customers to purchase, in order to avoid shielding the appearance of the bottle product, the shell 1 in the embodiment is composed of a transparent cover 101 and a side cover 102, and the accommodating cavity 15 for inserting the bottle neck is arranged in the transparent cover 101; in addition, the cover body for inserting the bottle neck is transparent, which helps the product manager to check the damage and locking of the appearance of the bottle product. Further, the transparent cover 101 and the side cover 102 are connected by the pin shaft 6, so that they can be rotated around the pin shaft 6 to be opened and closed, which facilitates unlocking of the bottle in the locked state.

[0071] It is worth noting that although the transparent cover 101 and the side cover 102 in the embodiment can be opened and closed, when the bottle needs to be locked, the transparent cover 101 and the side cover 102 do not need to be opened, based on the working principle of the protective cover introduced in the embodiment, the bottle to be locked can be directly inserted into the accommodating cavity 15 in the shell 1, when there are many bottles to be locked, the transparent cover 101 and the side cover 102 do not need to be frequently opened, which greatly improves the convenience and efficiency of installing the protective cover.

[0072] As one of the optional embodiments, the transparent cover 101 and the side cover 102 in the embodiment can be provided with the electronic tag mentioned above.

[0073] As a preferred solution, the bottle protective cover further comprises a locking mechanism, which 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 avoid that the transparent cover 101 and the side cover 102 are opened or forced to open during the locking of the inserted bottleneck, so that the protection of the bottle is invalidated, the present embodiment sets a locking mechanism to lock the transparent cover 101 and the side cover 102 when they are closed, and the locking mechanism needs to be unlocked before the transparent cover 101 and the side cover 102 can be opened, which further improves the anti-damage performance and anti-theft performance for the bottle.

[0075] As a preferred solution, the locking mechanism comprises a thimble 9 and a lock core 10; one side surface of the transparent cover 101 is provided with a support for fixing the thimble 9, and the lock core 10 is arranged on a side surface of the side cover 102 away from the accommodating cavity 15.

[0076] The lock core 10 comprises a lock core spring, a lock core seat attracted by a magnet, a plurality of (for example, 3) round steel beads, a cover body, and a lock core shell 1 arranged outside the cover body; when the thimble 9 is inserted into the lock core 10, the lock core seat is pushed forward by the lock core spring, so that the plurality of round steel beads are squeezed by the cover body to lock the thimble 9.

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

[0078] Specifically, the locking mechanism in the present embodiment is composed of the thimble 9 and the lock core 10. It can be understood that when it is necessary to lock the shell 1, 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 arranged on the side cover 102. During the insertion of the thimble 9 into the lock core 10, the lock core seat is pushed forward by the lock core spring, so that the plurality of round steel beads are squeezed by the cover body to lock the thimble 9, so that the thimble 9 cannot be pulled out. When it is necessary to unlock the locking mechanism, since the iron core seat contains a ferromagnetic block, a magnet is needed to attract the iron core seat to resist the forward thrust of the iron core spring, so that the plurality of round steel beads are released and cannot lock the thimble 9 again. The lock core 10 is converted to 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 thimble 9 for insertion into the lock core 10 is a smooth surface.

[0080] Further preferably, one end of the thimble 9 for insertion into the lock core 10 is in the shape of a spherical cap or a plane.

[0081] It is worth mentioning that the common top pin on the market is a pointed top pin, which is used to pierce the soft goods (such as clothes, towels, etc.) to be protected to lock, but the protective cover in the embodiment is mainly used to protect the bottle goods, and the pointed top pin in the prior art can be preferably not used, and the end of the top pin 9 for inserting the lock core 10 is limited to a smooth surface, which is preferably in the form of a spherical cap or a plane, which can prevent the operator from installing the protective cover from being stabbed, and improve the safety of product use.

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

[0083] It is worth mentioning that in order to further improve the locking accuracy and ensure that the top pin 9 located in the transparent cover 101 can be more accurately inserted into the lock core 10 of the side cover 102, the baffle member 11 can be additionally provided in the side cover 102, and the baffle member 11 is arranged above the lock core 10, so that the insertion direction of the top pin 9 can be limited during the insertion of the top pin 9 into the lock core 10, and the top pin 9 can be smoothly inserted into the lock core 10.

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

[0085] Specifically, the inner surface of the transparent cover 101 is also provided with an arc-shaped limiting member 12, and it can be understood that considering that the bottle neck surface of most bottle goods is in the form of a circular arc, the arc-shaped limiting member 12 can match the bottle neck contour of the bottle goods, which can increase the contact area between the arc-shaped limiting member 12 and the bottle neck, so that the bottle neck can be better limited, and damage to the outer surface of the bottle neck can be avoided. During the locking of the inserted bottle neck, the arc-shaped limiting member 12 can limit the inserted bottle neck together with the locking assembly, thereby increasing the resistance to prevent the bottle neck from swinging randomly in the accommodating cavity 15, and enhancing the locking effect of the bottle neck.

[0086] As a preferred solution, at least one component in the bottle protective 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 rotating clamping arm mechanism is made of recycled ABS.

[0089] In the embodiment, at least one component of the bottle protection cover is made of a recycled plastic in order to comply with the environmental protection concept. It can be understood that the components of the bottle protection cover are the components that constitute the bottle protection cover, such as the shell, the clamping arm, the rotating clamping member, and the like, which will not be described in detail herein.

[0090] The bottle protection cover provided by the embodiment of the utility model, through setting at least two rotating clamping arm mechanisms in the shell 1, and when the bottle protection cover is in the locking state and the accommodating cavity does not yet exist when the bottle neck is inserted, the straight line distance of the protruding tooth part on each rotating clamping arm mechanism to the opposite inner side surface of the accommodating cavity is not the same, one of the rotating clamping arm mechanisms can always find a suitable clamping position for bottles of different sizes, thereby effectively expanding the change range of the applicable bottle cap diameter and bottle neck length, and providing great convenience for commodity managers to uniformly purchase one kind of protection cover. In addition, the protruding tooth part 13 is arranged on one end of the rotating clamping arm mechanism close to the accommodating cavity 15, which can stably and reliably clamp the annular protruding part or the annular recessed part of various bottles, thereby ensuring that the smooth bottle can be clamped in the accommodating cavity 15.

[0091] Specifically, in one embodiment of the utility model, at least the bottle with a bottle cap diameter of 26.4mm-40.3mm and a bottle neck length of 25mm-132mm can be locked, the change range of the bottle cap diameter reaches 14.9mm, in another embodiment of the utility model, at least the bottle with a bottle cap diameter of 19.8mm-38.5mm and a bottle neck length of 24mm-116mm can be locked, the change range of the bottle cap diameter reaches 18.7mm, the change range of the bottle cap diameter is significantly improved from about 3mm-4mm corresponding to the bottle protection cover provided with the translation type clamping arm in the prior art to about 18mm-19mm, and the locking effect can also be ensured for the bottle with a bottle neck length greater than 116mm. Meanwhile, the embodiment of the utility model enables the operator to also operate with one hand to install the protection cover in the locking state, thereby greatly improving the use experience of the product.

[0092] In order to reflect that the embodiment of the utility model can effectively expand the change range of the applicable bottle cap diameter, the following several embodiments are described (the following embodiments all adopt the same locking mechanism, that is, all contain the thimble 9 and the lock core 10, and do not contain or contain the acoustic magnetic anti-theft alarm member, the radio frequency anti-theft alarm member or the RFID tag).

When the first clamping arm 2 connected with the first spring 4 is vertically compressed by 15 mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the first spring 4 is 3.3 N. When the second clamping arm 3 connected with the second spring 5 is vertically compressed by 15 mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the second spring 5 is 2.9 N. The bottle protection cover is used to lock the corresponding bottle in Examples 1-20, and it is found that the bottle can be pulled out of the accommodating cavity 15 by the strength of a human hand. That is, when the bottle protection cover with a relatively weak spring strength in the embodiment is in the locking state, although it has a good locking structure, the bottle in the accommodating cavity 15 can still be pulled out by the strength of a human hand.

[0157] Example 23 (change in clamping arm length and enhancement of spring strength can be applied to larger bottle opening size)

[0158] The bottle protection cover of the embodiment comprises a first rotating clamping arm mechanism, a second rotating clamping arm mechanism and a rotating buckle mechanism. The length of the clamping arm of the first rotating clamping arm mechanism is 56.9 mm, and the length of the clamping arm of the second rotating clamping arm mechanism is 46.4 mm. The end of the first rotating clamping arm mechanism and the end of the second rotating clamping arm mechanism are both provided with a convex tooth part 13, and the thickness of the convex tooth part is 1.5 mm. However, the two springs have a relatively low strength. When the first clamping arm 2 connected with the first spring 4 is vertically compressed by 15 mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the first spring 4 is 3.3 N. When the second clamping arm 3 connected with the second spring 5 is vertically compressed by 15 mm along the direction perpendicular to the central axis of the bottle inserted into the accommodating cavity 15, the radial locking force exerted by the second spring 5 is 2.9 N. The bottle protection cover is used to lock the corresponding bottle in Examples 1-20, and it is found that the bottle can be pulled out of the accommodating cavity 15 by the strength of a human hand. That is, when the bottle protection cover with a relatively weak spring strength in the embodiment is in the locking state, although it has a good locking structure, the bottle in the accommodating cavity 15 can still be pulled out by the strength of a human hand.
