Description

Technical Field

[0001] This utility model relates to the field of calibration equipment technology, and in particular to a calibration fixture and a medical automation device. Background Technology

[0002] In industrial production and experimental operations, many devices require precise alignment between the gripper and target objects such as test tubes. However, in practical applications, due to manufacturing errors, installation deviations, or changes in the operating environment, the gripper and test tube often become misaligned. This phenomenon can lead to the following problems:

[0003] 1. Inaccurate grasping leads to deviations in experimental results or operational failures;

[0004] 2. Increased wear and tear reduces the lifespan of the equipment;

[0005] 3. Reduced production efficiency and increased maintenance costs.

[0006] Most existing adjustment devices on the market are fixed structures, which cannot quickly and accurately adjust the coaxiality of the gripper and the test tube. Furthermore, some devices require complex calibration procedures, making them unsuitable for practical needs. Therefore, there is an urgent need for a device that can quickly and accurately adjust the coaxiality of the gripper and the target object. Utility Model Content

[0007] In order to solve at least one of the above-mentioned technical problems, the purpose of this utility model is to provide a correction fixture and a medical automation device.

[0008] To achieve the above objectives, the calibration fixture proposed in this utility model includes:

[0009] A first correction part and a second correction part, wherein the first correction part is provided with a first axis and the second correction part is provided with a second axis, and when the first correction part and the second correction part are spliced ​​together, the first axis and the second axis are coaxial;

[0010] The first calibration part is used to be installed on the first test part. The first test part is provided with a third axis. A first positioning component is provided between the first calibration part and the first test part. The first positioning component includes a first positioning part provided on the first calibration part and a second positioning part provided on the first test part. When the first calibration part is installed on the first test part, the first positioning part and the second positioning part cooperate to make the first axis coaxial with the third axis.

[0011] The second calibration unit is used to be installed on the second test unit. The second test unit is provided with a fourth axis. When the second calibration unit is installed on the second test unit, the second axis is coaxial with the fourth axis.

[0012] In one embodiment, the first correction part has a first straight shaft portion protruding from it, and the first axis is disposed in the first straight shaft portion. The second correction part has a first straight hole portion, and the second axis is disposed in the first straight hole portion. When the first straight shaft portion is inserted into the first straight hole portion, the first axis and the second axis are coaxial.

[0013] In one embodiment, the first positioning part is configured as a first arc-shaped surface, and the axis of the first arc-shaped surface is coaxial with the first axis.

[0014] In one embodiment, the second positioning part is configured as a second arc-shaped surface, and two second positioning parts are configured. The first positioning part is disposed between the two second positioning parts. The axis of the inscribed circle formed by the two second positioning parts is coaxial with the third axis. When the first positioning part and the second positioning part cooperate, the axes of the first arc-shaped surface and the second arc-shaped surface are coaxial.

[0015] In one embodiment, a second positioning component is provided between the second calibration part and the second test part. The second positioning component includes a third positioning part provided in the second calibration part and a fourth positioning part provided in the second test part.

[0016] The second calibration part is installed on the second test part, and the third positioning part cooperates with the fourth positioning part to make the second axis coaxial with the fourth axis.

[0017] In one embodiment, the third positioning part is configured as a third arc-shaped surface, and the axis of the third arc-shaped surface is coaxial with the second axis.

[0018] In one embodiment, the fourth positioning part includes a first positioning surface and a second positioning surface arranged at a preset angle;

[0019] The fourth positioning part is configured in two parts, and the axis of the inscribed circle constructed by the two fourth positioning parts is coaxial with the fourth axis. When the second correction part is installed on the second test part, the third positioning part is located between the two fourth positioning parts.

[0020] In one embodiment, the second correction part is provided with a second straight shaft portion, and the axis of the second straight shaft portion is configured as a second axis.

[0021] The third positioning part is configured as the outer surface of the second straight shaft part.

[0022] In one embodiment, the two fourth positioning portions can move closer to or further away from each other along a first direction;

[0023] The second positioning component further includes a first limiting surface disposed on the second correction part and a second limiting surface disposed on the second test part. The first limiting surface and the outer surface of the second straight shaft part are provided with a preset distance and are tangent to each other.

[0024] When the first limiting surface and the second limiting surface abut each other, and the two fourth positioning parts approach each other along the first direction, the third positioning part can be driven so that the second axis moves relative to the fourth axis along the direction of the fourth axis until the second axis is coaxial with the fourth axis.

[0025] This utility model also proposes a medical automation device, including a calibration fixture, a first test unit, and a second test unit, wherein the calibration fixture is any of the calibration fixtures described above;

[0026] The first test part and / or the second test part are configured as a clamping structure;

[0027] The clamping structure includes a first jaw and a second jaw that can move closer or further apart.

[0028] The technical solution of this utility model is achieved by having a first positioning part on the first calibration part and a second calibration part on the first test part. When the first calibration part is installed on the first test part, the first positioning part and the second positioning part make the first axis and the third axis coaxial, which can realize the rapid coaxiality of the first calibration part and the first test part. In particular, when the first test part is a clamping structure, as long as the first test part clamps the first calibration part, the coaxiality of the first test part and the first calibration part can be achieved. It should be further explained that the first calibration part can achieve coaxiality with the first test part during installation, which can shorten the time when the calibration fixture performs coaxial testing on the first test part and the second test part. It can be understood that when the test tube is placed on the second test part, the axis of the test tube is coaxial with the fourth axis on the second test part. That is to say, the coaxiality adjustment of the first test part and the second test part is completed, that is, the coaxiality adjustment of the first test part and the test tube placed on the second test part is completed. This solves the problem in existing technologies where the coaxiality of the gripper (clamping structure) and the test tube cannot be quickly adjusted. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0047] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] In industrial production and experimental operations, many devices require precise alignment between the gripper and target objects such as test tubes. However, in practical applications, due to manufacturing errors, installation deviations, or changes in the operating environment, the gripper and test tube often become misaligned. This phenomenon can lead to the following problems:

[0050] 1. Inaccurate grasping leads to deviations in experimental results or operational failures;

[0051] 2. Increased wear and tear reduces the lifespan of the equipment;

[0052] 3. Reduced production efficiency and increased maintenance costs.

[0053] Most existing adjustment devices on the market are fixed structures, which cannot quickly and accurately adjust the coaxiality of the gripper and the test tube. Furthermore, some devices require complex calibration procedures, making them unsuitable for practical needs. Therefore, there is an urgent need for a device that can quickly and accurately adjust the coaxiality of the gripper and the target object.

[0054] This utility model proposes a correction fixture 100 (reference). Figure 1 ), applied to medical automation equipment 400 (reference) Figure 2 The medical automation device 400 includes a clamping structure 700, which comprises a first gripper 710 and a second gripper 720 capable of moving closer to or further away from each other. Further, in some embodiments, the medical automation device 400 may have one clamping structure 700 or multiple clamping structures; this is not a limitation. However, the calibration fixture 100 in this application can also be applied to other devices requiring coaxiality calibration and is not limited to the aforementioned medical automation device 400.

[0055] It should be noted that when the medical automation equipment 400 is equipped with a clamping structure, the clamping structure is mainly responsible for clamping and transporting the target object, clamping and transporting the target object from the storage location to another location, or clamping the target object from another location to the storage or temporary storage location for storage.

[0056] When the medical automation device 400 is equipped with two clamping structures, one clamping structure is responsible for clamping and transporting the target object, and the other clamping structure is responsible for storing or temporarily storing the target object.

[0057] Please see Figure 1 In one embodiment of this utility model, the correction fixture 100 includes:

[0058] A first correction part 200 and a second correction part 300 are provided. The first correction part 200 is provided with a first axis, and the second correction part 300 is provided with a second axis. It should be noted that in some embodiments, the first correction part 200 is provided with a first straight shaft part 210, and the first axis is provided in the first straight shaft part 210. The second correction part 300 is provided with a first straight hole part 310, and the second axis is provided in the first straight hole part 310. When the first correction part 200 and the second correction part 300 are spliced, the first axis and the second axis are coaxial. That is, when the first straight shaft part 210 is inserted into the first straight hole part 310, the first axis and the second axis are coaxial. It can be understood that when the first straight shaft part 210 is inserted into the first straight hole part 310, the first straight hole part 310 is at least partially a straight hole structure. Specifically, the second axis is the axis of the straight hole structure.

[0059] However, this design is not limited to this. In some embodiments, the second correction part 300 may be provided with a first straight shaft part 210. In this case, the second axis is configured as the axis of the first straight shaft part 210, and the first correction part 200 is provided with a first straight hole part 310. In this case, the first axis is configured as the axis of the first straight hole part 310.

[0060] It should be noted that this embodiment does not limit the shape of the straight shaft portion and the hole portion. The straight shaft portion can be cylindrical, pentagonal, triangular, etc. Similarly, the straight hole structure of the straight hole portion can be cylindrical, pentagonal, triangular, etc., which are compatible with the straight shaft portion.

[0061] Furthermore, the medical automation device 400 also includes a first test unit 500 and a second test unit 600. The first calibration unit 200 is used to mount on the first test unit 500. The first test unit 500 is provided with a third axis. A first positioning component 800 (see reference) is provided between the first calibration unit 200 and the first test unit 500. Figure 4 The first positioning component 800 includes a first positioning part 810 disposed on the first correction part 200 and a second positioning part 820 disposed on the first test part 500. When the first correction part 200 is installed on the first test part 500, the first positioning part 810 and the second positioning part 820 cooperate to make the first axis coaxial with the third axis.

[0062] Furthermore, in some embodiments, the first test part 500 and / or the second test part 600 may be a clamping structure 700 with grippers. However, this design is not limited to this. In some embodiments, the first test part 500 and the second test part 600 may be other structures, such as components that need to be coaxially detected or adjusted. The specific component structure is not limited here, as long as it is a component that needs to be coaxially detected or adjusted.

[0063] Further, this embodiment takes the first test part 500 as a clamping structure 700 and the target object as a test tube as an example for explanation. The clamping structure 700 includes a first gripper 710 and a second gripper 720 that can move closer or further apart. The second test part 600 restricts the test tube through the structure so that the test tube is stored or temporarily stored in the second test part 600. It should be noted that temporary storage refers to the test tube being transported from other storage areas to the second test part 600 and restricted by the second test part 600 for a preset time. After the preset time, the test tube restricted by the second test part 600 is removed. Further, the second test part 600 can use a magnetic base, a groove structure with a specific shape (hemispherical), etc. to restrict the object. The first test part 500 is used to grasp the test tube on the second test part 600. At this time, the first test unit 500 clamps the first calibration unit 200 so that the first calibration unit 200 can be installed on the first test unit 500. It should be noted that the first positioning component 800 is disposed between the first calibration unit 200 and the first test unit 500. That is, the first positioning component 800 is disposed between the first calibration unit 200 and the first gripper 710 and the second gripper 720. Further, the first positioning component 800 includes a second positioning part 820 disposed on the first test unit 500. The first test unit 500 includes the first gripper 710 and the second gripper 720. At this time, the second positioning part 820 is disposed on both the first gripper 710 and the second gripper 720. It is understandable that when the first calibration part 200 is installed on the first test part 500, the two second positioning parts 820 on the first test part 500 can abut against the two first positioning parts 810 on the first calibration part 200, thereby causing the first test part 500 to clamp the first calibration part 200.

[0064] Furthermore, the second calibration unit 300 is used to be installed on the second test unit 600. The second test unit 600 is provided with a fourth axis. When the second calibration unit 300 is installed on the second test unit 600, the second axis and the fourth axis are coaxial. Furthermore, in some embodiments, the coaxiality of the second axis and the fourth axis can be achieved by other measuring tools, such as laser measuring equipment.

[0065] Furthermore, in some embodiments, reference is made to... Figure 4Both the first positioning part 810 and the second positioning part 820 can be configured as arc-shaped surfaces. The axes of the arc-shaped surfaces of the two first positioning parts 810 are coaxial with the first axis, and the axes of the inscribed circles formed by the arc-shaped surfaces of the two second positioning parts 820 are coaxial with the third axis. When the arc-shaped surfaces of the two second positioning parts 820 abut against the arc-shaped surfaces of the first positioning parts 810, the first axis and the third axis can be made coaxial. It should be noted that when the first test part 500 clamps the first correction part 200, the arc-shaped surfaces of the two second positioning parts 820 abut against the arc-shaped surfaces of the first positioning part 810. That is to say, in this embodiment, by providing a first correction part 200 on the first correction part 200... A positioning part 810 and a second positioning part 820 are provided on the first test part 500. When the first calibration part 200 is installed on the first test part 500, the first positioning part 810 and the second positioning part 820 make the first axis and the third axis coaxial, thereby realizing the rapid coaxiality of the first calibration part 200 and the first test part 500. In particular, when the first test part 500 is a clamping structure 700, as long as the first test part 500 clamps the first calibration part 200, the coaxiality of the first test part 500 and the first calibration part 200 can be achieved. It should be further noted that the first calibration part 200 can achieve the first calibration part 200 coaxiality during installation. The first test unit 500 is coaxial with the second test unit 600, which shortens the time required for the calibration fixture 100 to perform coaxial testing on the first test unit 500 and the second test unit 600. Coaxial testing of the second test unit 600 and the second calibration unit 300 can be achieved using other measuring tools, such as laser measuring equipment. It should be noted that by shortening the adjustment time of the first test unit 500 and the first calibration unit 200, the installation time of the calibration fixture and the first test unit 500 and the second test unit 600 can be shortened. When the first test unit 500 and the second test unit 600 are adjusted to be coaxial, the first calibration unit 200 and the second calibration unit 300 are also aligned. In coordination, the first straight shaft portion 210 is inserted into the first straight hole portion 310. When the first straight shaft portion 210 is inserted into the first straight hole portion 310, the first test portion 500 and the second test portion 600 are coaxially aligned. It can be understood that since the second test portion 600 has already been coaxially aligned with the first test portion 500, when the test tube is placed on the second test portion 600, the axis of the test tube is coaxial with the fourth axis on the second test portion 600. With the coaxiality adjustment of the first test portion 500 and the second test portion 600 completed, the coaxiality adjustment of the first test portion 500 and the test tube placed on the second test portion 600 can be achieved. This solves the problem of the gripper (clamping structure 700) and the test tube not being coaxial in the prior art.

[0066] Furthermore, it should be emphasized that the coaxiality between the axes described in this application refers to the axes being nearly coaxial, that is, when the first straight shaft portion 210 is inserted into the first straight hole portion 310, the first axis and the second axis are nearly coaxial, and the error between the first axis and the second axis that is within the tolerance range can be ignored and does not affect the accuracy between the first test portion 500 and the second test portion 600.

[0067] In one embodiment, reference Figure 4 The first positioning part 810 is configured as a first arc-shaped surface, and the axis of the first arc-shaped surface is coaxial with the first axis. However, this design is not limited to this. In some embodiments, the first positioning part 810 may be configured as two planes set at a preset angle, and the axes of the inscribed circles of the two planes are coaxial with the first axis.

[0068] In one embodiment, reference Figure 1 , Figure 4 The second positioning part 820 is configured as a second arc-shaped surface, the axis of which is coaxial with the third axis. When the first positioning part 810 and the second positioning part 820 cooperate, the axes of the first arc-shaped surface and the second arc-shaped surface are coaxial. However, this design is not limited to this. When the first test part 500 adopts the clamping structure 700, the second positioning part 820 is configured as two planes set at a preset angle, the axes of the inscribed circles of the two planes are coaxial with the third axis. However, this design is not limited to this. In some embodiments, the second positioning part 820 can be configured as three planes set at preset angles, the axes of the inscribed circles of the three planes are coaxial with the third axis.

[0069] In one embodiment, reference Figure 1 , Figure 3 , Figure 5A second positioning component 900 is provided between the second calibration part 300 and the second test part 600. The second positioning component 900 includes a third positioning part 910 disposed on the second calibration part 300 and a fourth positioning part 920 disposed on the second test part 600. The second calibration part 300 is mounted on the second test part 600. The third positioning part 910 and the fourth positioning part 920 cooperate to make the second axis coaxial with the fourth axis. It should be noted that in this embodiment, the second test part 600 is configured as a clamping structure 700. At this time, the second test part 600 clamps the second calibration part 300. The second calibration unit 300 is installed on the second test unit 600 in a manner that allows the second calibration unit 300 to be mounted on the second test unit 600. It should be noted that the second positioning component 900 is located between the second calibration unit 300 and the second test unit 600; that is, the second positioning component 900 is located between the grippers of the second calibration unit 300 and the second test unit 600. Further, the second positioning component 900 includes a fourth positioning part 920 located on the second test unit 600. The second test unit 600 employs a clamping structure 700, which includes a first gripper 710 and a second gripper 720. In this case, each gripper on the second test unit 600 is provided with a fourth positioning part 920. It is understood that when the second calibration unit 300 is mounted on the second test unit 600, the two fourth positioning parts 920 on the second test unit 600 can abut against the third positioning part 910 on the second calibration unit 300, thereby allowing the second test unit 600 to clamp the second calibration unit 300.

[0070] Furthermore, in some embodiments, both the third positioning part 910 and the fourth positioning part 920 can be configured as arc-shaped surfaces (not shown). Further, the axis of the arc-shaped surface of the third positioning part 910 is coaxial with the second axis, and the axis of the inscribed circle formed by the arc-shaped surfaces of the two fourth positioning parts 920 is coaxial with the fourth axis. When the arc-shaped surfaces of the two fourth positioning parts 920 abut against the arc-shaped surface of the third positioning part 910, the second axis and the fourth axis can be made coaxial. It should be noted that when the second test part 600 clamps the second correction part 300, the two fourth positioning parts 920 abut against the third positioning part 910. Thus, the second positioning assembly 900 enables the quick installation of the second correction part 300 and the second test part 600, achieving coaxiality and saving adjustment time. However, this design is not limited to this. In some embodiments, the third positioning part 910 can also be two planes set at a preset angle, and the axis of the inscribed circle formed by the two planes is coaxial with the second axis.

[0071] Furthermore, in one embodiment, reference is made to... Figure 5The fourth positioning part 920 includes a first positioning surface and a second positioning surface set at a preset angle, wherein the included angle between the first positioning surface and the second positioning surface can be set at an obtuse angle. Further, the third positioning part 910 can be configured as an arc-shaped surface (see...). Figure 1 Furthermore, the first positioning surface and the second positioning surface can be configured as planes. Two fourth positioning parts 920 are configured, and the axis of the inscribed circle constructed by the two fourth positioning parts 920 is coaxial with the fourth axis. When the second correction part 300 is installed on the second test part 600, the third positioning part 910 is located between the two fourth positioning parts 920. Furthermore, when the second test part 600 adopts a clamping structure 700, and the clamping structure 700 includes two grippers, then the fourth positioning part 920 is configured as two. When the second correction part 300 is installed on the second test part 600, the third positioning part 910 is located between the two fourth positioning parts 920. It should be noted that when the second correction part 300 is installed on the second test part 600, that is, the second test part 600 clamps the second correction part 300 through the two grippers. In this way, the second correction part 300 is installed on the second test part 600. When the two grippers clamp the second correction part 300, the two fourth positioning parts 920 can abut against the third positioning part 910. In this way, the fourth axis and the second axis can be quickly coaxialized. That is to say, while the second correction part 300 is installed, the second correction part 300 and the second test part 600 can also be made coaxial. This can reduce the time for adjusting the coaxiality of the second correction part 300 and the second test part 600. However, this design is not limited to this. In some embodiments, when there are three grippers, there are also three fourth positioning units 920.

[0072] In one embodiment, reference Figure 1 The second correction part 300 has a protruding second straight shaft part 320, the axis of which is configured as a second axis. It should be noted that a first straight hole part 310 is provided on the second straight shaft part. The third positioning part 910 is configured as the outer surface of the second straight shaft part. Further, in some embodiments, the second straight shaft part can be configured as a round shaft, in which case the outer surface of the second straight shaft part is an arc-shaped surface, and the third positioning part 910 is configured as an arc-shaped surface. It can be understood that the second test part 600 clamps the second correction part 300 by clamping the second straight shaft part. However, this design is not limited to this; in some embodiments, the second straight shaft part can be configured as a shaft member of other structures.

[0073] In one embodiment, reference Figure 3 , Figure 5The two fourth positioning parts 920 can move closer to or further away from each other along the first direction; the second positioning component 900 also includes a first limiting surface 930 provided on the second correction part 300 and a second limiting surface 940 provided on the second test part 600. The first limiting surface 930 is provided with a preset distance and is tangent to the outer surface of the second straight axis part 320; it should be noted that the second limiting surface 940 is also tangent to the inscribed circle constructed by the two fourth positioning parts 920.

[0074] Furthermore, when the first limiting surface 930 and the second limiting surface 940 abut each other, and the two fourth positioning parts 920 approach each other along the first direction, they can drive the third positioning part 910 to move the second axis relative to the fourth axis along the direction of the fourth axis until the second axis is coaxial with the fourth axis. The direction of the fourth axis is the extension direction of the fourth axis. In this embodiment, the extension direction of the fourth axis is the first direction. It can be understood that when the first limiting surface 930 and the second limiting surface 940 abut each other, the second axis and the fourth axis are arranged along the first direction. When the two fourth positioning parts 920 approach each other along the first direction, they can push against the second correction part 300 to move it, thereby causing the second axis to move relative to the fourth axis until the second axis is coaxial with the fourth axis.

[0075] Further, refer to Figure 1 In some embodiments, the second correction part 300 is provided with a limiting plate 330, wherein the first limiting surface 930 is provided on the limiting plate 330.

[0076] This utility model also proposes a medical automation device 400, see reference. Figure 2 The medical automation device 400 includes a calibration fixture 100, a first test unit 500, and a second test unit 600. The specific structure of the calibration fixture 100 is as described in the above embodiments. Since the medical automation device 400 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0077] In this configuration, the first test unit 500 and / or the second test unit 600 are configured as clamping structures 700. It is understood that both the first test unit 500 and the second test unit 600 in the medical automation device 400 can be configured as clamping structures 700, in which case the second test unit 600 uses the clamping structure 700 to restrict the object. Alternatively, only the first test unit 500 can be configured as a clamping structure 700. In this case, the second test unit 600 can use other structures to restrict the object, such as a magnetic base or a groove structure with a specific shape (hemispherical). In this case, the first test unit 500 is used to clamp and transport the object, and the second test unit 600 is used to store or temporarily store the object. Alternatively, only the second clamping part can be configured as a clamping structure 700. In this case, the second clamping part can restrict the object through the clamping structure 700 to store or temporarily store the object. The first test part 500 can be used to move the object. Specifically, the first test part 500 can move the object by magnetic attraction.

[0078] Furthermore, the clamping structure 700 includes a first gripper 710 and a second gripper 720 that can move closer together or further apart. However, this design is not limited to this. In some embodiments, the clamping structure 700 may also include a third gripper and a fourth gripper, and the multiple grippers can move closer together to clamp the object or further apart to release the object.

[0079] Further, refer to Figure 2 Taking a test tube as an example where both test parts are clamping structures, before performing the coaxiality test, the first calibration part 200 is installed on the first test part 500, and the second calibration part 300 is installed on the second test part 600. After the first calibration part 200 and the second calibration part 300 are installed, the positions of the first test part 500 and the second test part 600 are adjusted so that the first straight shaft part 210 is inserted into the first straight hole part 310 to complete the coaxiality adjustment of the first test part 500 and the second test part 600. After the coaxiality adjustment is completed, the positions of the first test part 500 and the second test part 600 are calibrated, and then the first calibration part 200 is removed from the first test part 500 and the second calibration part 300 is removed from the second test part 600. In this way, the coaxiality adjustment of the first test part 500 and the second test part 600 is completed by the calibration fixture 100.

[0080] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
