[0048] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0049] Embodiment 1

[0050] As Figures 1 to 13 shown, this embodiment provides a bottle protection device, which can clamp bottle bodies 2 of different sizes, and the operation of replacing the bottle body 2 is simple and the replacement efficiency is high.

[0051] Referring to Figure 1 and Figure 2 , the bottle protection device includes a base 1, a bottle protection component and an adjustment component. The base 1 can support the bottle body 2; the bottle protection component includes a fixed protection piece 31 and a movable protection piece stacked on the base 1. A plurality of first grooves 311 are provided on the fixed protection piece 31. The movable protection piece includes a plurality of movable plates 32 arranged at intervals. A second groove 321 is provided on each movable plate 32. The plurality of second grooves 321 correspond to the plurality of first grooves 311 one by one. The first grooves 311 and the second grooves 321 are both used to clamp the bottle body 2, and the sizes of the first grooves 311 and the second grooves 321 are different; the adjustment component is movably arranged on the base 1 and is connected to the plurality of movable plates 32. When the adjustment component is driven to move relative to the base 1, the adjustment component can drive the plurality of movable plates 32 to extend or retract relative to the fixed protection piece 31.

[0052] The bottle protection device provided in this embodiment has a bottle body 2 that can be placed on a base 1. The body of the bottle body 2 is clamped within a first groove 311 or a second groove 321, which can ensure the stability of the bottle body 2 during the processes of filling and transporting the bottle body 2. The driving and adjusting assembly is movable relative to the base 1. The adjusting assembly can drive a plurality of movable plates 32 connected thereto to extend or retract relative to the fixed protection member 31, enabling the bottle protection device to complete the adjustment of the positions of the plurality of movable plates 32 in one go, thereby improving the rate of bottle body 2 replacement. When the plurality of movable plates 32 extend relative to the fixed protection member 31, the bottle body 2 will be clamped within the second groove 321; when the plurality of movable plates 32 retract relative to the fixed protection member 31, the bottle body 2 will be clamped within the first groove 311. Since the sizes of the first groove 311 and the second groove 321 are different, the bottle protection device can change the size of the bottle body 2 that can be clamped by simply controlling the adjusting assembly to drive the movable plates 32 to move. While expanding the applicability of the bottle protection device, it also simplifies the steps of replacing the bottle body 2 of different sizes, improving the replacement efficiency.

[0053] The fixed protection member 31 can be located on the side of the movable protection member away from the base 1 or between the movable protection member and the base 1, as long as the fixed protection member 31 can remain stationary on the base 1 during the process of filling the bottle body 2 and the movable plates 32 of the movable protection member can extend and retract relative to the fixed protection member 31.

[0054] In some embodiments, the number of movable plates 32 can be less than the number of first grooves 311. At this time, a plurality of second grooves 321 can be provided on the movable plates 32 so that the number of first grooves 311 is the same as the total number of second grooves 321 on all movable plates 32, ensuring a one-to-one correspondence between the first grooves 311 and the second grooves 321.

[0055] In this embodiment, refer to Figure 3 and Figure 4 , the cross-section of the fixed protection member 31 is a ring. The first groove 311 is provided at the edge of the fixed protection member 31. A plurality of first grooves 311 are arranged at intervals along the circumference of the fixed protection member 31, and the first groove 311 is recessed towards the center of the fixed protection member 31; the movable protection member is coaxially arranged with the fixed protection member 31. The cross-section of the movable plate 32 is a sector. A plurality of movable plates 32 are arranged at intervals along the circumference of the fixed protection member 31. The second groove 321 is provided on the outer side of the movable plate 32 and also recessed towards the center of the fixed protection member 31. The movable plate 32 can move radially along the fixed protection plate under the drive of the adjusting assembly, so as to extend or retract relative to the fixed protection member 31.

[0056] In other embodiments, the cross-section of the fixed protection member 31 can also be circular, polygonal or square-ring-shaped, etc., and the cross-section of the movable plate 32 can also be rectangular or trapezoidal, etc.

[0057] In this embodiment, the size of the second groove 321 is smaller than the size of the first groove 311. Refer toFigure 1 and Figure 2 The size of the bottle body B is smaller than that of the bottle body A. The second groove 321 can hold the bottle body B, and the first groove 311 can hold the bottle body A. In other embodiments, the size of the second groove 321 can also be larger than that of the first groove 311.

[0058] Optionally, referring to Figure 1 、 Figure 5 and Figure 6 The adjusting assembly includes a rotating ring 41 rotatably arranged on the base 1. A guiding groove 411 corresponding to each of the plurality of movable plates 32 is arranged on the rotating ring 41. A first connecting column 5 is arranged on each movable plate 32. The first connecting column 5 passes through the corresponding guiding groove 411 and is in sliding fit with the guiding groove 411. When the rotating ring 41 rotates, the groove wall of the guiding groove 411 can drive the first connecting column 5 to drive the movable plate 32 to extend or retract relative to the fixed protector 31. Among them, the first connecting column 5 is used to connect the rotating ring 41 and the corresponding movable plate 32, so that the plurality of movable plates 32 can extend or retract relative to the fixed protector 31 simultaneously under the drive of the corresponding first connecting column 5.

[0059] Referring to Figure 5 and Figure 6 The extending direction of the guiding groove 411 forms an included angle with both the rotating direction of the rotating ring 41 (the X direction in Figure 6 ) and the moving direction of the movable plate 32 (the Y direction in Figure 6 ), so that when the rotating ring 41 rotates, the groove wall of the guiding groove 411 can squeeze the first connecting column 5, and then push the first connecting column 5 to drive the movable plate 32 to move.

[0060] Exemplarily, referring to Figure 5 and Figure 6 When the cross-sections of both the fixed protector 31 and the rotating ring 41 are circular rings, the rotating ring 41 is coaxially arranged with the fixed protector 31, the movable plate 32 can move along the radial direction of the fixed protector 31, and the guiding groove 411 extends gradually closer to the center of the circle along the circumferential direction.

[0061] The fixed protector 31 is fixed to the base 1. The movable protector can be stacked on the side of the fixed protector 31 away from the base 1, or can also be stacked on the side of the fixed protector 31 close to the base 1. When the rotating ring 41 is arranged on the side of the movable protector away from the fixed protector 31, the first connecting column 5 is fixed to the corresponding movable plate 32. When the rotating ring 41 is arranged on the side of the fixed protector 31 away from the movable plate 32, a first sliding groove in sliding fit with the first connecting column 5 is arranged on the fixed protector 31. One end of the first connecting column 5 passes through the first sliding groove and is fixed to the corresponding movable plate 32, and the other end of the first connecting column 5 passes through the corresponding guiding groove 411.

[0062] Exemplarily, the first connecting column 5 and the movable plate 32 can be connected by bolts. Refer to Figure 4 and Figure 5 , two layers of stepped holes 322 are provided on the movable plate 32. One end of the first connecting column 5 connected to the movable plate 32 is provided with a first threaded hole that is threadedly engaged with the bolt. One end of the first connecting column 5 provided with the first threaded hole is inserted into the stepped hole 322, and this end face can abut against a stepped surface of the stepped hole 322. The screw rod of the bolt passes through the stepped hole 322 and is fastened in the first threaded hole, and the head of the screw rod abuts against another stepped surface of the stepped hole 322 to connect the first connecting column 5 with the corresponding movable plate 32, and at the same time can prevent the bolt from affecting the stacking of the movable plate 32 and the fixed guard 31.

[0063] In an alternative embodiment, refer to Figure 5 , the adjusting assembly further includes a connecting ring 42 and a plurality of second connecting columns 43. The connecting ring 42 and the rotating ring 41 are coaxially and spaced apart. One end of each of the plurality of second connecting columns 43 is connected to the rotating ring 41, and the other end of each of the plurality of second connecting columns 43 is connected to the connecting ring 42. An operating portion 44 is provided on the connecting ring 42, and the operating portion 44 is configured to drive the connecting ring 42 to drive the rotating ring 41 to rotate. Among them, the second connecting column 43 can separate the connecting ring 42 from the rotating ring 41, and the plurality of second connecting columns 43 can stably support the connecting ring 42, and at the same time can drive the rotating ring 41 to rotate when the connecting ring 42 rotates.

[0064] When the bottle type needs to be changed, the staff drives the connecting ring 42 to rotate through the operating portion 44. The plurality of second connecting columns 43 simultaneously move along the circumferential direction of the connecting ring 42 following the connecting ring 42, thereby driving the rotating ring 41 to rotate. The groove wall of the guiding groove 411 will squeeze and push the corresponding first connecting column 5 to move, so that the corresponding movable plate 32 can extend or retract relative to the fixed guard 31.

[0065] Furthermore, refer to Figure 5 , Figure 7 and Figure 8 , a first boss 51 is provided on the first connecting column 5 between the movable plate 32 and the rotating ring 41, and a second boss 431 is provided at one end of the second connecting column 43 connected to the rotating ring 41, so that the rotating ring 41 is located between the first boss 51 and the second boss 431 in the vertical direction to limit the vertical movement of the rotating ring 41.

[0066] Exemplarily, the second connecting column 43 and the rotating ring 41 can be connected by bolts. Refer to Figure 5 and Figure 6A two-layer stepped hole 412 is provided on the rotating ring 41, and a threaded hole 41 that matches the bolt thread is provided at one end of the second connecting column 43 connected to the rotating ring 41. One end of the second connecting column 43 provided with the threaded hole 41 is inserted into the stepped hole 412, and the end face can abut against a stepped surface of the stepped hole 412. The screw of the bolt passes through the stepped hole 412 and is fastened in the threaded hole 41. The head of the screw abuts against the other stepped surface of the stepped hole 412 to connect the second connecting column 43 with the rotating ring 41. At the same time, it can also prevent the bolt from protruding from the rotating ring 41 to avoid affecting the rotation of the rotating ring 41.

[0067] In this embodiment, refer to Figure 8 and Figure 9 , there are multiple operating parts 44, and they are arranged one by one corresponding to the multiple second connecting columns 43. One end of the operating part 44 connected to the connecting ring 42 is provided with a thread of a certain length, and one end of the second connecting column 43 connected to the connecting ring 42 is provided with a threaded hole three that matches the thread of the operating part 44, and the connecting ring 42 is provided with connecting holes 421 corresponding to the multiple second connecting columns 43. One end of the operating part 44 provided with the thread can pass through the corresponding connecting hole 421 and be fastened in the threaded hole three of the corresponding second connecting column 43, so as to connect the operating part 44 with the corresponding second connecting column 43, and fix the connecting ring 42 between the operating part 44 and the second connecting column 43.

[0068] Further, see Figure 8 and Figure 9 The cross-sectional dimensions of the end of the operating portion 44 away from the corresponding second connecting column 43 and the cross-sectional dimensions of the second connecting column 43 are both larger than the dimensions of the corresponding connecting hole 421 to limit the displacement of the connecting ring 42 in the vertical direction.

[0069] In other embodiments, one or more operating parts 44 may be provided, and are not provided corresponding to the plurality of second connecting columns 43. As long as the staff can drive the connecting ring 42 to rotate through the operating part 44, the operating part 44 and the second connecting group can be fixedly connected to the connecting ring 42 by fasteners such as bolts.

[0070] Furthermore, in order to ensure the stability of the connecting ring 42 and to make the rotating ring 41 evenly stressed, a plurality of second connecting columns 43 are arranged at intervals along the circumference of the connecting ring 42, and the angles between any two adjacent second connecting columns 43 and the center of the connecting ring 42 are equal. For example, when four second connecting columns 43 are provided, the angles between any two adjacent second connecting columns 43 and the center of the connecting ring 42 are both 90 degrees.

[0071] Optionally, see Figure 2 , Figure 9 and Figure 10, the bottle protection device further includes a locking member 6 disposed on the base 1. The locking member 6 has a clamping portion 61. A plurality of locking holes 422 are provided on the connecting ring 42. The clamping portion 61 can be selectively inserted into any one of the locking holes 422 to limit the rotation position of the rotating ring 41, so that the movable plate 32 does not move during the filling of the bottle body 2, ensuring the stability of the bottle body 2 during filling.

[0072] The plurality of locking holes 422 are arranged at intervals along the circumferential direction of the connecting ring 42, and the distance between two adjacent locking holes 422 is determined by the moving distance of the movable plate 32.

[0073] Refer to Figure 9 and Figure 10 , the locking member 6 is disposed on the fixed protection member 31 through a column 62 extending in the vertical direction. The locking member 6 can move along the extending direction of the column 62. Moving the locking member 6 upward can disengage the clamping portion 61 from the corresponding locking hole 422, and the rotation of the connecting ring 42 is no longer restricted; after the movable plate 32 extends or retracts relative to the fixed protection member 31, move the locking member 6 downward to insert the clamping portion 61 into the corresponding locking hole 422, and the rotation of the connecting ring 42 is restricted, thereby realizing the restriction of the rotation position of the rotating ring 41.

[0074] Further, since the movable plate 32 has only two positions of extending and retracting relative to the fixed protection member 31, it is sufficient to provide two locking holes 422 on the connecting ring 42.

[0075] In another alternative embodiment, the adjusting assembly may further include only the second connecting column 43. The second connecting column 43 is fixed to the rotating ring 41, and the staff drives the rotating ring 41 to rotate through the second connecting column 43.

[0076] Optionally, refer to Figure 1 and Figure 5 , the bottle protection device further includes a plurality of fixed struts 7. The plurality of fixed struts 7 are arranged at intervals along the circumferential direction on the fixed protection member 31. The rotating ring 41 is located in the annular area formed by surrounding the plurality of fixed struts 7, and the rotating ring 41 is rotatably engaged with each of the plurality of fixed struts 7 to restrict the rotation area of the rotating ring 41, so that the rotating ring 41 can only rotate relative to the plurality of fixed struts 7 on the base 1 and cannot move.

[0077] Exemplarily, the fixed protection member 31 is provided with threaded holes four 312 corresponding to the plurality of fixed struts 7 one by one. One end of the fixed strut 7 connected to the fixed protection member 31 is provided with a thread threadedly engaged with the threaded hole four 312 to threadedly connect the fixed strut 7 to the fixed protection member 31.

[0078] In some embodiments, one end of the fixed support column 7 is fixed to the fixed guard 31, and the other end can be fixedly connected to the base 1. The rotating ring 41 is located between the fixed guard 31 and the base 1, so that the fixed support column 7 can not only restrict the rotation area of the rotating ring 41 but also connect the fixed guard 31 and the base 1. Among them, the fixed support column 7 and the base 1 can be fixedly connected by threads in the same way as the fixed support column 7 and the fixed guard 31.

[0079] Optionally, referring to Figure 5 and Figure 11 , a rotating groove 71 is provided on the fixed support column 7, and the edge of the rotating ring 41 is snapped into the rotating groove 71 and rotates in cooperation with the rotating groove 71, so that the fixed support column 7 can not only restrict the displacement of the rotating ring 41 in the horizontal direction but also restrict the displacement of the rotating ring 41 in the vertical direction.

[0080] Exemplarily, referring to Figure 5 and Figure 11 , the fixed support column 7 extends in the vertical direction. The cross-sectional dimension of the connection part between the fixed support column 7 and the fixed guard 31 is smaller than the cross-sectional dimension of the fixed support column 7 outside the fixed guard 31. The height of the rotating groove 71 in the vertical direction matches the thickness of the rotating ring 41. The rotating groove 71 is an annular groove provided around the fixed support column 7, so that the top surface and the bottom surface of the rotating ring 41 can contact the upper groove wall and the lower groove wall of the rotating groove 71 respectively to restrict the displacement of the rotating ring 41 in the vertical direction.

[0081] Referring to Figure 4 and Figure 5 , in some embodiments, when the fixed support column 7 needs to pass through the corresponding movable plate 32 to be connected to the fixed guard 31, a second sliding groove 323 is provided on the movable plate 32. The second sliding groove 323 extends along the direction in which the movable plate 32 expands and contracts relative to the fixed guard 31. The fixed support column 7 passes through the second sliding groove 323 and slides in cooperation with the second sliding groove 323, so that the fixed support column 7 does not interfere with the movement of the movable plate 32.

[0082] Furthermore, the length of the second sliding groove 323 matches the distance by which the movable plate 32 expands and contracts relative to the fixed guard 31 to further prevent the movable plate 32 from moving during the filling process of the bottle body 2.

[0083] In an optional embodiment, referring to Figure 1 and Figure 5, two groups of fixed protectors 31 and movable protectors are arranged at intervals along the height direction of the bottle body 2 on the base 1. The two groups of movable protectors are located between the two groups of fixed protectors 31, and the rotating ring 41 is located between the two groups of movable protectors. Both ends of the fixed support column 7 are fixedly connected to the two groups of fixed protectors 31 respectively. Both ends of the first connecting column 5 are fixedly connected to two opposite movable plates 32 in the two groups of movable protectors respectively. And the multiple first grooves 311 of one group of bottle protecting assemblies can correspond to the multiple first grooves 311 of the other group of bottle protecting assemblies one by one, so that the bottle body 2 can be clamped by the two groups of bottle protecting assemblies during the filling process, improving the firmness of clamping of the bottle body 2, and also enabling the bottle protecting device to clamp the bottle body 2 with a lower height, expanding the applicability of the bottle protecting device.

[0084] Specifically, the bottle body 2 is placed vertically on the base 1. The fixed protector 31 is a circular ring structure. From top to bottom along the vertical direction, they are the first group of fixed protectors 31, the first group of movable protectors, the rotating ring 41, the second group of movable protectors, the second group of fixed protectors 31 and the base 1. The second group of fixed protectors 31 is fixedly connected to the base 1. The upper end of the first connecting column 5 is fixedly connected to the corresponding movable plate 32 of the first group. The lower end of the first connecting column 5 is fixedly connected to the corresponding movable plate 32 of the second group. The first connecting column 5 passes through the corresponding guiding groove 411 along the vertical direction. The upper end of the fixed support column 7 passes through the corresponding movable plate 32 of the first group and is fixedly connected to the first group of fixed protectors 31. The lower end of the fixed support column 7 passes through the corresponding movable plate 32 of the second group and is fixedly connected to the second group of fixed protectors 31. The rotating groove 71 is located at the middle position of the fixed support column 7 and is in rotational cooperation with the rotating ring 41. Multiple second connecting columns 43 pass through the inside of the ring of the first group of fixed protectors 31. The connecting ring 42 is coaxially arranged above the first group of fixed protectors 31. The locking member 6 is fixed on the top surface of the first group of fixed protectors 31 through the column 62.

[0085] Exemplarily, refer to Figure 1 and Figure 5 , six first grooves 311 are provided on the fixed protector 31. Each group of bottle protecting assemblies includes six movable plates 32. A first connecting column 5 and two fixed support columns 7 are arranged between two vertically opposite movable plates 32. The two fixed support columns 7 are symmetrically arranged on the corresponding movable plates 32. The first connecting column 5 is located at the middle position of the corresponding movable plate 32 and can drive the corresponding movable plate 32 to move evenly as a whole.

[0086] The steps for the bottle protecting device provided in this embodiment to replace the bottle type of the bottle body 2 are as follows:

[0087] The staff disengages the clamping portion 61 of the locking member 6 from the corresponding locking hole 422, and then drives the connecting ring 42 to rotate through the operating portion 44. The second connecting column 43 moves as the connecting ring 42 rotates, driving the rotating ring 41 to rotate. The groove wall of the guiding groove 411 will push each first connecting column 5 to drive the corresponding movable plate 32 to move. Relative sliding occurs between the fixed support column 7 and the second sliding groove 323, and the movable plate 32 moves relative to the corresponding fixed support column 7, that is, the movable plate 32 extends or retracts relative to the fixed protection member 31. When the fixed support column 7 abuts against the side wall of the second sliding groove 323, the staff inserts the clamping portion 61 of the locking member 6 into the corresponding locking hole 422 to complete the replacement of the bottle shape.

[0088] In another optional embodiment, the two groups of fixed protection members 31 may also be located between the two groups of movable protection members, or one group of movable protection members is located between the two groups of fixed protection members 31, and the other group of movable protection members is located on the side of the group of fixed protection members 31 away from the other group of fixed protection members 31.

[0089] Optionally, referring to Figure 12 , a limiting member 8 is provided on the base 1, and a limiting card slot 313 is provided on the lowermost fixed protection member 31 of the two groups of fixed protection members 31. The limiting member 8 can be clamped with the limiting card slot 313 to fix the fixed protection member 31 to the base 1.

[0090] In this embodiment, the limiting card slot 313 includes a first slot section 3131 and a second slot section 3132 that are connected and communicated. The size of the first slot section 3131 is larger than the size of the second slot section 3132. The limiting member 8 can pass through the first slot section 3131 and slide into the second slot section 3132 through the first slot section 3131 to fix the fixed protection member 31 to the base 1.

[0091] Exemplarily, referring to Figure 12 , the second slot section 3132 is stepped. The limiting member 8 includes a limiting head and a limiting rod portion. The cross-sectional dimension of the limiting head is larger than the cross-sectional dimension of the limiting rod portion. When the limiting member 8 is clamped into the second slot section 3132, the limiting rod portion passes through the second slot section 3132, and the limiting head abuts against the stepped surface of the second slot section 3132.

[0092] The limiting member 8 is fixed on the base 1 and does not move. When installing the fixed protection member 31, first vertically pass the limiting member 8 through the first slot section 3131, and then rotate the fixed protection member 31 so that the limiting member 8 slides into the second slot section 3132 through the first slot section 3131, and the fixed protection member 31 can be fixed on the base 1. When disassembling the fixed protection member 31, rotate the fixed protection member 31 so that the limiting member 8 disengages from the second slot section 3132.

[0093] Further, bolts can be additionally provided between the fixed protector 31 and the base 1. That is, after the limiting member 8 is snapped into the second groove section 3132, the bolts are passed through the fixed protector 31 and fastened to the base 1 to prevent the fixed protector 31 from rotating and disengaging from the limiting member 8.

[0094] In some embodiments, the limiting member 8 can also be a bolt. When installing the fixed protector 31, first place the fixed protector 31 on the base 1, then pass the bolt through the first groove section 3131 and fasten it to the base 1, and finally, the fixed protector 31 can be fixed to the base 1 by rotating the fixed protector 31.
