Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mixing equipment, and in particular to a trolley and a liquid dispensing system for a split-type liquid dispensing system. Background Technology
[0002] In the pharmaceutical manufacturing process, the pharmaceutical ingredient preparation system is a core component of the entire production process. Existing liquid preparation systems mainly consist of two parts: a liquid preparation device and a trolley. The liquid preparation device includes a tank for mixing raw materials and a mounting frame, while the trolley includes a carriage body, rollers mounted on the carriage body, and a stirring mechanism. In use, the trolley is moved under the liquid preparation device, and the stirring mechanism is used to mix the raw materials in the tank.
[0003] In existing liquid preparation systems, the liquid preparation device is located above the trolley, and a mounting frame is installed on the liquid preparation device. The top of the trolley is equipped with a roller assembly that mates with the mounting frame, and the inner wall of the roller assembly is movably connected to the surface of the mounting frame. In use, the trolley is pushed so that the roller assembly is aligned with the mounting frame, the limiting groove on the roller assembly engages with the surface of the mounting frame, and the trolley is pushed again so that the roller assembly rolls along the surface of the mounting frame.
[0004] However, in the above-mentioned scheme, the trolley has two sets of rollers distributed along its length (i.e., along its installation direction with the reaction vessel), and the trolley is in a horizontal state, with both sets of rollers supported on the ground. In use, the trolley is directly moved horizontally to a preset position below the reaction vessel. Due to the trolley's lack of flexibility, the pushing process is quite laborious, making it difficult to suspend the trolley under the reaction vessel. Furthermore, to ensure the trolley's stability and prevent it from tipping over, the trolley's center of gravity is generally located between the two sets of rollers along its length, making it difficult to concentrate near any one set. If it is necessary to press down on one end of the trolley to tilt it and thus align the limiting hub with the guide rail, a large force is required to tilt the trolley due to its forward center of gravity, making the operation laborious. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a trolley and liquid preparation system for a split-type liquid preparation system.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A trolley for a split-type liquid dispensing system, the liquid dispensing system further including a liquid dispensing device, the liquid dispensing device including a tank and a mounting frame disposed below the tank, the trolley including a stirring mechanism for stirring the liquid in the tank;
[0008] The trolley includes a connecting frame and a gripping part, a supporting part, a first hanging rod, and a mating part disposed on the connecting frame; the gripping part and the first hanging rod are located on both sides of the stirring mechanism along the length of the connecting frame, so that when the gripping part is pressed down, the first hanging rod can rise and be suspended from the mounting frame; the mating part is used to cooperate with the first hanging rod to suspend the entire trolley at a preset position below the tank; wherein...
[0009] The support includes a first support and a second support; the first support is one or more wheels arranged in the width direction of the connecting frame; a line segment L1 is drawn from the contact point between the first support and the ground to connect the second support, and the angle between L1 and the stirring mechanism is an acute angle.
[0010] In the above solution, by setting a gripping part, a first hanging rod and a cooperating part on the connecting frame, the trolley can be suspended to a preset position below the tank, thereby enabling the weight monitoring of the entire liquid preparation system. This allows the amount of raw materials added to be determined directly by monitoring the weight of the entire liquid preparation system, which is beneficial for operators and ensures the accuracy of liquid preparation.
[0011] Furthermore, by setting the first support part as one or more wheels in the width direction of the connecting frame, and by reasonably setting the positions of the first support part, the second support part, and the stirring mechanism (i.e., the angle between line segment L1 and the axis of the stirring mechanism is an acute angle), it is possible to ensure that only the first support part contacts the ground when the trolley is pushed. That is, there is only one support position in the length direction of the trolley (which can be a fulcrum or several fulcrums that coincide in the width direction). This makes the steering adjustment of the trolley more flexible, and thus allows for more flexible matching of the position of the liquid dispensing device. This allows the trolley to be pushed into the installation space of the liquid dispensing device, making it easier for the first hanging rod to be suspended on the mounting frame. At the same time, since only the first support part contacts the ground during the trolley's pushing process, it is easier to control the center of gravity of the entire trolley to be near the first support part, making it easier for the trolley to tilt when the grip is pressed down, and easier for the first hanging rod to be suspended on the mounting frame.
[0012] Furthermore, the first and second support parts work together to increase the number of fulcrums on the length of the mounting frame when placing the trolley, thereby ensuring the stable placement of the trolley.
[0013] Preferably, the mating part is a second hanging rod rotatably mounted on the connecting frame, the second hanging rod being located between the stirring mechanism and the gripping part; and when the trolley is located at a preset position below the tank, the second hanging rod can be suspended from the mounting frame.
[0014] In the above scheme, the trolley can be suspended by the cooperation of the second hanging rod and the first hanging rod. The second hanging rod is set between the mixing mechanism and the grip, which facilitates the operation of the operator. On the other hand, the second hanging rod and the first hanging rod are located on both sides of the mixing mechanism, which makes the force on the first hanging rod and the first hanging rod more even and increases the stability of the trolley suspension.
[0015] Preferably, the first hanging rod is fixed on the connecting frame; multiple second hanging rods are provided, and / or the second hanging rods can be movably arranged in the length direction of the connecting frame.
[0016] In the above solution, by fixing the first hanging rod to the connecting frame, the first hanging rod can be stably suspended on the mounting frame and can guide the trolley to a preset position below the tank.
[0017] Furthermore, when multiple second hanging rods are fixedly installed on the connecting frame, it ensures that at least one second hanging rod can be suspended from the mounting frame, thus adapting to mounting frames of different lengths (i.e., adapting to dispensing devices of different sizes). Similarly, when the second hanging rod is movable along the length of the connecting frame, it can be adjusted to be suspended from the mounting frame, thus ensuring that it can work with the first hanging rod to suspend the trolley from the mounting frame, thereby adapting to mounting frames of different lengths (i.e., adapting to dispensing devices of different sizes).
[0018] Preferably, the connecting frame includes a first mounting rod and a second mounting rod perpendicularly disposed on the first mounting rod, the second mounting rod extending away from the gripping part, the first support part being disposed at the end of the first mounting rod, and the second support part being disposed at the end of the second mounting rod; the first support part and the second support part are located on both sides of the stirring mechanism in the length direction of the connecting frame.
[0019] In the above solution, the reasonable arrangement of the first support, the second support, and the stirring mechanism along the length of the connecting frame facilitates greater stability of the trolley when placed separately from the liquid preparation device. Furthermore, the perpendicularity of the first and second mounting rods ensures that the second support is at a certain distance from the ground when the trolley is pushed, thus facilitating flexible adjustment of the trolley.
[0020] Preferably, the first mounting rod also has a support platform located above the first support portion, and the stirring mechanism and / or driving mechanism are mounted on the support platform.
[0021] In the above scheme, since the mixing mechanism and the drive mechanism account for a large proportion of the entire cart, the mixing mechanism and the drive mechanism are installed through the support platform. This facilitates the adjustment of the installation position of the drive mechanism and the mixing mechanism to adjust the weight of the entire cart, so that the center of gravity of the cart is closer to the first support part. This not only increases the flexibility of the cart's steering adjustment, but also makes it easier for the cart to tilt up with the contact point between the first support part and the ground as the fulcrum when the grip part is pressed down.
[0022] Preferably, the trolley further includes a drive mechanism and a control mechanism, which are located on the side of the stirring mechanism near the gripping part along the length of the connecting frame; and the distance between the drive mechanism and the stirring mechanism is smaller than the distance between the drive structure and the control mechanism.
[0023] In the above scheme, by reasonably setting the positions of the drive mechanism, control mechanism, stirring mechanism and the first support part, the counterweight on both sides of the first support part can be adjusted, thereby ensuring that the trolley is pushed more stably, and at the same time, it is also convenient for the first hanging rod to be suspended on the mounting frame.
[0024] Preferably, the connecting frame extends directionally in its length direction, and when the connecting frame is set parallel to the ground, with the contact point between the first support and the ground as the fulcrum, the torque of the stirring mechanism is M1, and the torque of the driving mechanism, the control mechanism and the gripping part is M2. Then M1 / M2 satisfies: 0.8≤M1 / M2≤1.2.
[0025] In the above scheme, by reasonably setting the ratio range of M1 / M2, the user can control the tilt of the cart when applying a small force. That is, when a small pressure is applied to the grip, the first hanging rod can be raised and suspended on the mounting frame, which makes it easier to suspend the cart on the mounting frame of the liquid dispensing device.
[0026] Preferably, the stirring mechanism is height-adjustable; the stirring mechanism is a magnetic stirring device.
[0027] A split-type liquid dispensing system includes a liquid dispensing device and a trolley as described above; the liquid dispensing device includes a tank, a mounting bracket, and legs for supporting the tank, the legs being located on both sides in the width direction of the tank, and the gap between the legs forming an installation space for the trolley to enter; the mounting bracket is disposed within the installation space, and the mounting bracket has a limiting protrusion for limiting the degree of pushing the trolley in and a positioning groove for engaging a second hanging rod.
[0028] In the above scheme, the first hanging rod is limited by setting a limiting protrusion on the mounting frame, thereby limiting the degree of pushing the trolley in. The positioning groove on the mounting frame can cooperate with the second hanging rod to suspend the trolley to the preset position of the liquid dispensing device.
[0029] Preferably, the first hanging rod of the trolley is provided with a limiting plate, which can limit the mounting frame in the width direction; and / or, the end face of the first hanging rod in the width direction limits the mounting frame in the width direction.
[0030] In the above scheme, by limiting the width direction with the limiting plate and the mounting frame, and by limiting the width direction with the first hanging rod and the mounting frame, the trolley can be guided to move along the extension direction of the mounting frame, so that the length direction of the trolley coincides with the extension direction of the mounting frame, thus avoiding the trolley from deviating in the width direction.
[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0032] 1. By setting a gripping part, a first hanging rod, and a mating part on the connecting frame, the trolley can be suspended to a preset position below the tank, so that the trolley is completely detached from the ground. This enables the weight monitoring of the entire liquid preparation system, and allows the amount of raw materials to be added to be determined directly by monitoring the weight of the entire liquid preparation system. This is beneficial for operators and ensures the accuracy of liquid preparation.
[0033] Furthermore, by setting the first support part as one or more wheels in the width direction of the connecting frame, and by reasonably setting the positions of the first support part, the second support part, and the stirring mechanism (i.e., the angle between line segment L1 and the axis of the stirring mechanism is an acute angle), it is possible to ensure that only the first support part contacts the ground when the trolley is pushed. That is, there is only one support position in the length direction of the trolley (which can be a fulcrum or several fulcrums that coincide in the width direction). This makes the steering adjustment of the trolley more flexible, and thus allows for more flexible matching of the position of the liquid dispensing device. This allows the trolley to be pushed into the installation space of the liquid dispensing device, making it easier to adjust the position of the first hanging rod and suspend it on the mounting frame. At the same time, since only the first support part contacts the ground during the trolley's movement, it is easier to control the center of gravity of the entire trolley to be near the first support part, making it easier for the trolley to tilt when the grip is pressed down, and easier for the first hanging rod to be suspended on the mounting frame.
[0034] Furthermore, the first and second support parts work together to increase the number of fulcrums on the length of the mounting frame when placing the trolley, thereby ensuring the stable placement of the trolley.
[0035] 2. The rational arrangement of the first support, second support, and stirring mechanism along the length of the connecting frame facilitates greater stability of the trolley when placed separately from the liquid preparation device. Furthermore, the perpendicularity of the first and second mounting rods ensures that the second support is at a certain distance from the ground when the trolley is pushed, thus facilitating flexible adjustment of the trolley.
[0036] 3. By reasonably setting the ratio range of M1 / M2, the user can control the tilt of the cart when applying a small force. That is, when a small pressure is applied to the grip, the first hanging rod can be raised and suspended on the mounting frame, which makes it easier to suspend the cart on the mounting frame of the liquid dispensing device.

[0050] Example 1
[0051] See Figures 1 to 3 This utility model provides a trolley for a split-type liquid dispensing system. The liquid dispensing system also includes a liquid dispensing device, which includes a tank 101 and a mounting frame 102 located below the tank 101. The trolley includes a stirring mechanism 1 for stirring the liquid in the tank 101.
[0052] Specifically, the trolley includes a connecting frame 2 and a gripping part 3, a support part 4, a first hanging rod 5, and a mating part 6 disposed on the connecting frame 2; the gripping part 3 and the first hanging rod 5 are located on both sides of the stirring mechanism 1 in the length direction of the connecting frame 2, so that when the gripping part 3 is pressed down, the first hanging rod 5 can rise and be suspended on the mounting frame 102, and the mating part 6 is used to cooperate with the first hanging rod 5 to suspend the trolley as a whole at a preset position below the tank 101.
[0053] Furthermore, the coordination between the dispensing device and the trolley is as follows: the trolley is pushed to move its first hanging rod 5 to align with one end of the mounting bracket 102, and then the gripping part 3 is pressed down to raise the first hanging rod 5 to a position higher than the mounting bracket 102. Afterwards, the dispensing device (i.e., Figures 1-3 The trolley is pushed in the X direction to suspend the first hanging rod 5 on the mounting frame 102, and then pushed further towards the liquid dispensing device to suspend the trolley at a preset position below the liquid dispensing device. Finally, the entire trolley is suspended on the mounting frame 102 by using the mating part 6 and the first hanging rod 5.
[0054] It is easy to understand that by setting the gripping part 3, the first hanging rod 5 and the cooperating part 6 on the connecting frame 2, the trolley can be suspended to a preset position below the tank 101, so that the trolley is completely off the ground. This enables the weight monitoring of the entire liquid preparation system, and the amount of raw materials added can be determined directly by monitoring the weight of the entire liquid preparation system. This is beneficial to the operator and ensures the accuracy of the liquid preparation system.
[0055] It is worth noting that the "preset position" refers to the position of the trolley below the tank 101. The liquid dispensing position varies depending on the tank volume, and is determined by the position where the stirring mechanism 1 can stir the liquid inside the tank 101. Preferably, the "preset position" can be set to the position of the trolley when the central axis of the stirring mechanism 1 is close to the central axis of the tank 101. With the connecting frame 2 in a horizontal position as a reference, the "length direction of the connecting frame 2" indicates the direction of travel of the connecting frame 2 when it is pushed into the liquid dispensing device on a horizontal plane. Figures 1 to 3 The X direction and its opposite direction are shown in the diagram; correspondingly, "width direction of connecting frame 2" refers to the side direction of connecting frame 2 on the horizontal plane, perpendicular to the length direction, that is... Figures 1 to 3 The Y direction and the opposite direction of the Y direction are shown.
[0056] See Figures 1 to 3 The support part 4 includes a first support part 41 and a second support part 42; the first support part 41 is one or more wheels arranged in the width direction of the connecting frame 2; a line segment L1 is drawn from the contact point between the first support part 41 and the ground to connect the second support part 42, and the angle formed by L1 and the axis of the stirring mechanism 1 is an acute angle.
[0057] It is easy to understand that by setting the first support part 41 as one or more wheels in the width direction of the connecting frame 2, and by reasonably setting the positions of the first support part 41, the second support part 42, and the stirring mechanism 1 (that is, making the angle between line segment L1 and the axis of the stirring mechanism 1 acute), it is possible to ensure that only the first support part 41 is in contact with the ground when the trolley is pushed. That is, there is only one support position in the length direction of the trolley (which can be a fulcrum or several fulcrums that coincide in the width direction). This makes the steering adjustment of the trolley more flexible, and thus allows for more flexible matching of the position of the liquid preparation device. This allows the trolley to be pushed into the installation space of the liquid preparation device, making it easier for the first hanging rod 5 to be suspended on the mounting frame 102. At the same time, since only the first support part 41 is in contact with the ground during the trolley's movement, it is easier to control the center of gravity of the entire trolley to be near the first support part 41, making it easier for the trolley to tilt when the grip part 3 is pressed down, and easier for the first hanging rod 5 to be suspended on the mounting frame 102.
[0058] Furthermore, the first support part 41 and the second support part 42 cooperate with each other to increase the number of support points of the trolley in the length direction of the mounting frame 102 when placing the trolley, thereby ensuring the stable placement of the trolley.
[0059] In this embodiment, the second support part 42 is also provided with a wheel. A tangent is drawn to the wheel of the second support part 42 through the contact point C1 between the first support part 41 and the ground. The intersection of this tangent and the wheel of the second support part 42 is C2. The line connecting C1 and C2 is L1. The central axis of the stirring mechanism 1 is L2. It should be noted that in this embodiment, L1 and L2 are two skew lines. The angle between the two lines can be measured using the translation method, the three cosine theorem method, or the triangular pyramid method; for example... Figure 2 As shown, in this embodiment, the first support part 41 and the second support part 42 are on the same vertical plane, and the vertical plane is parallel to the central axis L2 of the stirring mechanism 1. By translation, a line L2' parallel to L2 can be drawn at point C1, and the angle A between L2' and L1 is the angle formed between L1 and L2.
[0060] Of course, in other embodiments, the second support part 42 can also be set as other non-wheel support structures that can work with the first support part 41 to achieve stable placement of the trolley, while not affecting the pushing and steering adjustment of the trolley.
[0061] See Figures 1 to 3The mating part 6 is a second hanging rod 61 rotatably mounted on the connecting frame 2. The second hanging rod 61 is located between the stirring mechanism 1 and the gripping part 3. When the trolley is located at a preset position below the tank 101, the second hanging rod 61 can be suspended from the mounting frame 102. That is, the trolley can be suspended by the cooperation of the second hanging rod 61 and the first hanging rod 5. The second hanging rod 61 is located between the stirring mechanism 1 and the gripping part 3, which facilitates the operation of the operator. On the other hand, the second hanging rod 61 and the first hanging rod 5 are located on both sides of the stirring mechanism 1, which makes the force on the first hanging rod 5 and the second hanging rod 61 more even and increases the stability of the trolley suspension.
[0062] Specifically, the first hanging rod 5 is fixed on the connecting frame 2, so that the first hanging rod 5 can be stably suspended on the mounting frame 102, and can cooperate with the mounting frame to guide the trolley to a preset position below the tank 101.
[0063] Furthermore, multiple second hanging rods 61 are provided, ensuring that at least one second hanging rod 61 can be suspended from the mounting bracket 102, thereby adapting to mounting brackets 102 of different lengths, and thus enabling the trolley to be adapted to liquid dispensing devices of different sizes. See also Figure 1 and Figure 2 In this embodiment, there are two second hanging rods 61, which are rotatably mounted on the mounting bracket 102.
[0064] Of course, in other embodiments, the second hanging rod 61 can also be fixed on the connecting frame 2, and the second hanging rod 61 can also be movably arranged in the length direction of the connecting frame 2, such as being able to slide relative to the mounting frame 102 along its length direction.
[0065] See Figures 1 to 3 The connecting frame 2 includes a first mounting rod 21 and a second mounting rod 22 vertically disposed on the first mounting rod 21. The second mounting rod 22 extends away from the gripping part 3. A first support part 41 is disposed at the end of the first mounting rod 21, and a second support part 42 is disposed at the end of the second mounting rod 22. The first support part 41 and the second support part 42 are located on both sides of the stirring mechanism 1 along the length of the connecting frame 2.
[0066] It is easy to understand that the reasonable arrangement of the first support part 41, the second support part 42, and the stirring mechanism 1 along the length of the connecting frame 2 helps to make the trolley more stable when placed separately from the liquid preparation device. In addition, the first mounting rod 21 and the second mounting rod 22 are perpendicular to each other, which ensures that the second support part 42 is at a certain distance from the ground when the trolley is pushed, thus facilitating the flexible adjustment of the trolley.
[0067] Furthermore, such as Figure 1-3As shown, the first mounting rod 21 also has a support platform 51, which is located above the first support part 41. The cart also includes a drive mechanism 7. Since the drive mechanism 7 accounts for a relatively large proportion of the entire cart, and is mounted on the support platform 51, the weight distribution of the entire cart can be adjusted by adjusting the mounting positions of the drive mechanism 7 and the stirring mechanism 1. This ensures that the center of gravity of the cart is closer to the first support part 41, increasing the flexibility of the cart's steering adjustment and facilitating the lifting of the first hanging rod 5 mounted at one end of the cart. In other embodiments, the stirring mechanism 1 is also mounted on the support platform 51. It should be understood that since the stirring mechanism 1 accounts for a relatively large proportion of the entire cart, by setting a support platform 51 above the first mounting rod 21 for mounting the stirring mechanism 1, the center of gravity of the stirring mechanism 1 is closer to the first support part 41 after installation. This increases the flexibility of the cart's steering adjustment and makes it easier for the cart to lift using the contact point between the first support part 41 and the ground as a fulcrum when the gripping part 3 is pressed down.
[0068] See Figures 1 to 3 The cart also includes a control mechanism 8. By reasonably setting the installation positions of the stirring mechanism 1, the drive mechanism 7 and the control mechanism 8, the stability and pushing flexibility of the cart can be guaranteed.
[0069] Specifically, along the length of the connecting frame 2, the drive mechanism 7 and the control mechanism 8 are located on the side of the stirring mechanism 1 closer to the gripping part 3; and the distance between the drive mechanism 7 and the stirring mechanism 1 is less than the distance between the drive structure and the control mechanism 8. That is, through the reasonable arrangement of the positions of the drive mechanism 7, the control mechanism 8, the stirring mechanism 1 and the first support part 41, the counterweights on both sides of the first support part 41 can be adjusted, thereby ensuring that the trolley is more stable when pushed, and at the same time, it is also convenient for the first hanging rod 5 to be suspended on the mounting frame 102.
[0070] Furthermore, the connecting frame 2 extends directionally in its length direction, and when the connecting frame 2 is set parallel to the ground, with the contact point between the first support part 41 and the ground as the fulcrum, the torque of the stirring mechanism 1 is M1, and the torque of the driving mechanism 7, the control mechanism 8 and the gripping part 3 is M2. Then the ratio of M1 / M2 can be set to 0.8, 1 or 1.2.
[0071] It should be understood that the ratio of M1 / M2 should satisfy: 0.8≤M1 / M2≤1.2. At this time, the user can control the tilt of the cart with a small force. That is, when a small pressure is applied to the grip part 3, the first hanging rod 5 can be raised and suspended on the mounting frame 102, which makes it easier to suspend the cart on the mounting frame 102 of the liquid dispensing device.
[0072] Specifically, the stirring mechanism 1 is liftable; the stirring mechanism 1 is a magnetic stirring device.
[0073] Example 2
[0074] See Figures 4 to 8 Based on the above embodiment one, this embodiment also provides a split-type liquid dispensing system, including a liquid dispensing device and a trolley provided in embodiment one. The liquid dispensing device includes a tank 101, a mounting frame 102, and legs 103 for supporting the tank 101. The legs 103 are located on at least two sides in the width direction of the tank 101, and the gap between the legs 103 forms an installation space 104 for the trolley to enter. The mounting frame 102 is located within the installation space 104.
[0075] Specifically, in order to ensure the stability of the stability support, the tank body 101 is also provided with legs 103 at the end of the installation space 104 away from the trolley installation port. That is, the tank body 101 is provided with legs 103 on both sides in the width direction and on one side in the length direction (i.e. the side away from the trolley installation port) to ensure the stability of the tank body 101.
[0076] Furthermore, the liquid preparation device also includes a base 105, the lower end of which is provided with several wheels 106, and one end of which is provided with a gripping rod 107, thereby facilitating the driving of the liquid preparation device or the movement of the liquid preparation device and the trolley.
[0077] Furthermore, the mounting bracket 102 has a limiting protrusion 1021 for limiting the degree of pushing the trolley in and a positioning groove 1022 for engaging with the second hanging rod 61. It is easy to understand that by providing the limiting protrusion 1021 on the mounting bracket 102 to limit the first hanging rod 5, the degree of pushing the trolley in can be limited. By providing the positioning groove 1022 on the mounting bracket 102, engagement with the second hanging rod 61 can be achieved, so as to suspend the trolley at the preset position of the liquid dispensing device.
[0078] See Figures 5 to 7 The first hanging rod 5 is provided with a limiting plate 9, which can limit the width of the mounting bracket 102.
[0079] Furthermore, the end face of the first hanging rod 5 in the width direction forms a limit with the mounting bracket 102 in the width direction.
[0080] It is easy to understand that by limiting the width direction with the limiting plate 9 and the mounting bracket 102, and by limiting the width direction with the first hanging rod 5 and the mounting bracket 102, the trolley can be guided to move along the extension direction of the mounting bracket 102, so that the length direction of the trolley coincides with the extension direction of the mounting bracket 102, thus avoiding the trolley from deviating in the width direction.
[0081] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
