Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will be further illustrated below through specific embodiments.

[0034] The concept of this utility model is as follows: by suspending a long strip of tablets at two points, and then hanging a hook on the tablets, applying a certain amount of gravity to the lower part of the hooks with an adjustable value, and observing the appearance of the tablets, this can be used as an indicator to judge the load-bearing capacity of the tablets, and further as an indicator to evaluate the strength and effectiveness of the tablet pressing process.

[0035] To realize this inventive concept, the present invention provides the following embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following embodiments are merely illustrations and evidence of specific implementations of the present invention, and do not limit the scope of protection of the present invention. Based on the inventive concept and embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: In this example, the tablet 10 is a long strip-shaped oral tablet for bovine use, which is cylindrical in shape. The tablet 10 is approximately as follows: Figure 1 As shown in Tablet 10.

[0037] like Figure 1-3 As shown, this embodiment includes a bracket 1 with two support bases 101, each disc-shaped. A vertical support rod 102 is fixed to the upper end of each support base 101, and an arc-shaped plate is fixed to the upper end of the support rod 102, forming a slot 2. This embodiment also includes a question mark hook 3, which consists of a hook rod and an arc-shaped hook at the tail. A weight holder 4 is connected to the free end of the hook rod. This embodiment also includes weights 5.

[0038] In this embodiment, the elongated tablet 10 is placed on two arc-shaped slots 2, and then the hook 3 is hung on the tablet 10 between the two slots 2, preferably on the middle part of the tablet 10. Then, a weight 5 of the required weight is placed into the weight holder 4. After placing the weight 5, the appearance of the tablet 10 is observed to determine its load-bearing capacity. Because standard weights are used, the gravity value is readable, and weights 5 of the required weight can be placed as needed.

[0039] Preferably, the support rod 102 is height-adjustable, and is a telescopic rod with adjustable height. The height of the support rod can be adjusted to easily accommodate hooks, weight racks, and electric push rods of different specifications.

[0040] Example 2: In this example, the tablet 10 is a long strip-shaped oral tablet for bovine use, which is cylindrical in shape. The shape of the tablet 10 is approximately as follows: Figure 5 As shown in Tablet 10.

[0041] In this embodiment, such as Figure 4-6As shown, two slots 2 are provided on the bracket 1. The shape and structure of the bracket 1 itself are not specifically limited, as long as the supporting effect is met. Of course, the bracket structure described in Embodiment 1 can also be used. An electric push rod 6 is installed at the bottom of the bracket 1 between the two slots 2. The upper end of the electric push rod 6 is connected to one end of the tension sensor 7 via a first tension rod 11. The other end of the tension sensor 7 is connected to a second tension rod 12, and the other end of the second tension rod 12 is connected to a hook 3.

[0042] In use, the long, narrow tablet 10 is placed on the two slots 2. Then, the hook 3 is hung on the tablet 10. The electric push rod 6 is then used to apply downward force, connecting the tension sensor 7 to the display device. Alternatively, the tension sensor 7 can be an electronic hand scale. The value displayed on the device indicates the applied weight to the tablet 10. As the applied weight reaches the set value, the shape of the tablet 10 is observed to determine its load-bearing capacity.

[0043] In addition, the first tension rod 11 can be made into an elastic telescopic rod. The basic structure of the elastic telescopic rod is that a sliding rod is slidably installed inside a sleeve, and a spring is installed between the sliding rod and the sleeve, so that the sliding rod needs to overcome the elastic force of the spring when moving upward or downward. The elastic telescopic rod allows the electric push rod 6 to expand its stroke during downward pulling, and has a certain degree of flexibility.

[0044] In addition, the first tension rod 11 and the electric push rod 6 can be rotatably connected, and the direction of rotation can be the plane where the opening of the hook 3 is located. The rotatable connection makes it more convenient to remove or attach the hook 3 to the tablet 10. For example, when it is necessary to remove the hook 3 from the tablet 10, the electric push rod 6 is pushed upward to detach the hook 3 from the tablet 10, and then the hook 3 can be held and tilted backward.

[0045] Example 3 is a supplement to Examples 1 and 2. Regarding the specific structure of the support 1, a connecting rod 8 is provided in the lower part of the support 1. When the length of the connecting rod 8 is adjusted, the two slots 2 can move closer or further apart. The distance between the two slots can be adjusted, facilitating the measurement of tablets of different specifications, lengths, or measurement requirements.

[0046] like Figure 3-8As shown, we take the specific structure of Embodiment 1 as an example. A connecting rod 8 is connected between the lower parts of the two support rods 102. The connecting rod 8 consists of a first rod 801 and a second rod 802. One end of the first rod 801 is fixed to a support rod 102, and the other end of the first rod 801 has an adjusting groove 803. One end of the second rod 802 is integrally connected to an adjusting slide rod 804, which slidably connects within the adjusting groove 803. The other end of the second rod 802 is connected to another support rod 102. In this way, the connecting rod 8 is made into a telescopic rod, allowing relative movement between the first rod 801 and the second rod 802. Preferably, the adjusting slide rod 804 can be in friction fit within the adjusting groove 803, allowing the adjusting slide rod 804 to slide within the adjusting groove 803. During the sliding process, a certain force is required to overcome the frictional force, achieving stability in maintaining the current position between the two, thus ensuring the stability of the tablet determination process.

[0047] Preferably, if the electric push rod 6 is to remain aligned with the center position of the tablet 10 after the length of the connecting rod 8 is adjusted, the position of the electric push rod 6 also needs to be adjusted. To address this, we designed a specific structure where the total length of the second rod 802 plus its integrally connected adjusting slide rod 804 is less than the length of the first rod 801. This ensures that regardless of the length adjustments of the first rod 801 and the second rod 802, the center position of the connecting rod 8 is always on the first rod 801, and the mounting seat 9, when positioned between the two slots, is always on the first rod 801. As a preferred embodiment, the connecting rod 8 is a long, rectangular rod. A mounting seat 9, movable along the length of the first rod 801, is provided on the first rod 801. The mounting seat 9 is a rectangular block with a rectangular hole fitted into the shape of the connecting rod 8, through which it fits onto the first rod 801. To ensure the mounting base 9 remains stably positioned after movement, a second threaded hole 901 is provided at the upper end of the mounting base 9. The second threaded hole 901 penetrates downwards through a rectangular hole, and a second locking bolt 902 is screwed into the second threaded hole 901. When the mounting base 9 needs to be moved, the second locking bolt 902 is loosened, and the mounting base 9 can be moved. Once the mounting base 9 is in the appropriate position, the second locking bolt 902 is tightened, causing its bottom to press against the first rod 801, thus positioning the mounting base 9 in its current position. The mounting base is adjustable, allowing it to always remain between the two slots, facilitating the determination of the tablet's load-bearing capacity.

[0048] Preferably, a positioning mechanism for adjusting the length of the connecting rod 8 is provided. A first threaded hole 805 is formed on the upper side of the first rod 801, penetrating downwards into the adjusting slide groove 803. A first locking bolt 806 is screwed into the first threaded hole 805. When it is necessary to adjust the distance between the two slots 2, this is achieved by adjusting the length of the connecting rod 8. When adjusting the length of the connecting rod 8, the first locking bolt 806 is loosened, and the relative distance between the first rod 801 and the second rod 802 is adjusted. After adjusting to the appropriate position, the first locking bolt 806 is tightened so that the lower end of the first locking bolt 806 abuts against the adjusting slide rod 804. By using the first locking bolt 806 for fastening, the connecting rod 8 can be stably maintained at its current length, thereby ensuring the stability of the distance between the two slide grooves.

[0049] By adjusting the distance between the two slots 2, tablets 10 of different lengths can be accommodated. Gravity is applied using a combination of an electric push rod 6 and a tension sensor 7, making the adjustment of the applied gravity more convenient. The magnitude of the applied force during adjustment can be detected in real time by the tension sensor 7, and the value is displayed through a data acquisition and display unit. The applied gravity can be adjusted linearly, making gravity adjustment more convenient and precise. Preferably, the tension sensor and the electric push rod can be connected to a controller. The controller sets the required tension value, and when the tension is reached, it is detected by the sensor, which transmits a signal to the controller to stop the electric push rod or perform other necessary actions. This makes the tension adjustment more precise and facilitates the determination of the tablet's load-bearing capacity.
