Description

Movable carrying device

Technical Field

The utility model particularly relates to a movable carrying device.

Background

In the industries of logistics transportation and the like, articles are generally required to be transported. When it is desired to transport an item, it is often necessary to first transport the item from one location to another, for example, to transport the item from a container to a transport vehicle.

At present, the articles are generally carried by manual means. For example, a plurality of workers are respectively located in a container, on the ground and on a transport vehicle, and convey goods located in the container to the transport vehicle by means of manual transfer. However, since the efficiency of transportation by manual operation is low at the present stage, it is difficult to efficiently transport by manual operation and it is necessary to invest a lot of manpower resources to perform the operation when a large amount of transportation needs are met. It is also possible to use simple mechanical devices that are manually engaged to carry items, but are typically only fixed in a particular position. For example, a carrier may place an item in a container on a conveyor from a receiving end of the conveyor and then move the item to an output end using the conveyor. However, in general, when performing work, it is necessary to transport articles in a certain area, and the conveyor belt cannot move by itself, so that a transport worker needs to transport the articles from another place to the receiving end of the conveyor belt.

Therefore, it is desirable to provide a mobile handling device.

The present embodiment relates to a movable conveying device that can be used for conveying an object to be conveyed. The conveyance device may be referred to as a conveyor, a conveyance robot, a loader, a loading/unloading robot, a transfer device, an automatic conveyance device, or the like. In the carrying device according to the present embodiment, the drive mechanism drives the transport mechanism and the base to move so that the upstream end of the transport mechanism is positioned at a predetermined position, and the object to be carried is received.

Hereinafter, the carrying device according to the present embodiment will be described in detail with reference to the drawings.

Fig. 1 is an overall schematic view showing a carrying device 20 according to an example of the present invention. Fig. 2 is a schematic diagram showing a conveying device 20 according to an example of the present invention for conveying an object 2.

It should be noted that the relative position and relative direction terms such as "above", "upward", "below", "downward", "up and down", "left", "right", "left and right", "front", "rear", "front and rear" in this document refer to the normal operation attitude and should not be considered as restrictive.

In the present embodiment, which of the conveying devices 20 can be used for conveying the object 2 to be conveyed (see fig. 1 and 2). That is, the conveying device 20 can convey the object 2 to be conveyed from a predetermined position. In some examples, the handling device 20 may be configured to be movable.

In some examples, the handling device 20 may be used for handling the object 2 to be handled within a container. When the handling device 20 handles the object 2 to be handled in the container, the handling device 20 is at least partially placed in the container.

In the present embodiment, the object 2 to be transported may be a regular object such as a carton, a steel material, or a wood material. For example, as shown in fig. 2, the object 2 to be carried may be a box-like object. In other examples, the object 2 to be carried may be an irregularly shaped object.

In the present embodiment, the conveying device 20 may include a conveying mechanism 21, a base 200, and a driving mechanism 23 (see fig. 1). The base 200 may be configured to support the transport mechanism 21, the transport mechanism 21 may be configured to transport the object 2 to be transported, and the drive mechanism 23 may be configured to drive the transport mechanism 21 and the base 200.

In some examples, the handling device 20 may further comprise a connecting device 40 (see fig. 1).

Hereinafter, for convenience of description, a direction in which the carrying device 20 approaches the object 2 to be carried is understood as "toward the front" (a direction indicated by D1 in the embodiment of fig. 1), and accordingly, a direction in which the carrying device 20 moves away from the object 2 to be carried is understood as "toward the rear" (a direction indicated by D2 in the embodiment of fig. 1). And with reference to the normal operation attitude, the horizontal leftward direction is understood as "toward the left" (the direction indicated by D3 in the embodiment of fig. 1), and accordingly, the horizontal rightward direction is understood as "toward the right" (the direction indicated by D4 in the embodiment of fig. 1); a vertically upward direction is understood as "toward the upper side" (the direction indicated by D5 in the embodiment of fig. 1), and correspondingly, a vertically downward direction is understood as "toward the lower side" (the direction indicated by D6 in the embodiment of fig. 1). It should be noted that the above relative position and relative direction terms refer to a general operation posture and a general operation manner, and should not be construed as being limiting.

In some examples, the base 200 may be used to support the transport mechanism 21. The base 200 can perform a function of balancing weight when the conveying device 20 conveys the object 2 to be conveyed.

In some examples, the base platform 200 may be substantially rectangular parallelepiped in shape.

In some examples, the base 200 may have a receiving space (not shown) therein for receiving the bearing blocks, and the weight of the bearing table 201 may be adjusted by adding or subtracting the bearing blocks to or from the receiving space. In this case, the conveying device 20 can be adapted to convey objects 2 to be conveyed of different weights.

In some examples, the base 200 may be configured to be movable in a direction approaching or moving away from the object 2 to be conveyed so that the conveying mechanism 21 is movable in a direction approaching or moving away from the object 2 to be conveyed.

In some examples, the base 200 may have rollers disposed at the bottom of the base 200 to allow the base 200 to move (not shown). For example, the rollers may be disposed at four corners of the bottom of the base 200. In this case, the movement and turning of the base 200 can be facilitated.

In some examples, the outer peripheral region of the submount 200 may have a baffle (see fig. 1). In this case, a dust-proof function can be achieved.

In some examples, the handling device 20 may include a connection substrate 41 for connecting the transfer mechanism 21 and the substrate table 200. In some examples, the transport mechanism 21 may be disposed above the base 200.

In some examples, the handling device 20 may include a transport mechanism 21 and a drive mechanism 23 (see fig. 2 and 3). The conveying mechanism 21 may be used to convey the object 2 to be conveyed, and the driving mechanism 23 may drive the conveying mechanism 21 to move to a predetermined position. In this case, the conveyance mechanism 21 is driven by the driving mechanism 23 to move to a predetermined position, and the object 2 to be conveyed is conveyed via the conveyance mechanism 21.

In some examples, the conveying mechanism 21 may have an upstream end 211 near the object 2 to be conveyed and a downstream end 212 far from the object 2 to be conveyed.

In some examples, when the object 2 to be conveyed is conveyed, the object 2 to be conveyed is received from the upstream end 211 of the conveying mechanism 21 and conveyed toward the downstream end 212 of the conveying mechanism in the conveying direction. The direction from the upstream end 211 to the downstream end 212 of the conveying mechanism 21 may be a conveying direction (i.e., a direction C2 in the embodiment shown in fig. 1).

In some examples, such as in the embodiment shown in fig. 2, the object 2 to be conveyed may be conveyed from the upstream end 211 to the downstream end 212 of the conveying mechanism 21 in the conveying direction.

In some examples, the conveyance direction may be a length direction of the conveyance mechanism 21. In some examples, the transport mechanism 21 may extend along the conveyance direction.

In some examples, the transport mechanism 21 may have a first carrying face S1. When conveying the object 2, the object 2 may be received from the upstream end 211 of the conveying mechanism 21 and conveyed toward the downstream end 212 of the conveying mechanism 21 via the first conveying surface S1 in the conveying direction.

In some examples, the transport mechanism 21 may include a carriage 35. The carrier 35 may be used to carry the object 2 to be carried. When an article is transported, the object 2 to be transported can be placed on the carrier 35 and transported.

In some examples, the carrier 35 may include first and second oppositely disposed side panels 351, 352. The first side plate 351 and the second side plate 352 may extend along the conveying direction.

In some examples, the first and second side plates 351, 352 may be connected by fixed rollers located between the first and second side plates 351, 352 and orthogonally connected with the first and second side plates 351, 352, respectively. The number of the fixed roller shafts may be one or more.

In some examples, the carrier 35 may include two pulleys provided at both ends of the carrier 35, and an endless belt wound around the two pulleys (see fig. 2). The conveyor belt may rotate with rotation of one or both pulleys. In this case, when the pulley rotates in the conveying direction, the conveyor belt can rotate in the conveying direction in accordance with the rotation of the pulley, and the object 2 to be conveyed placed on the conveyor belt can be conveyed in the conveying direction. That is, the object 2 to be conveyed located at the upstream end 211 of the conveying mechanism 21 can be conveyed to the downstream end 212 in the conveying direction by the conveyor belt. In addition, the conveyor belt may form the first carrying face S1.

In addition, in some examples, the conveyor belt may also rotate in a direction opposite to the conveying direction under the rotation of the pulleys. In this case, the object 2 to be conveyed at the downstream end 212 of the conveying mechanism 21 may be conveyed to the upstream end 211 by the conveyor belt in a direction opposite to the conveying direction.

In some examples, the carrier 35 may also transport the object 2 to be transported by roller conveyance (not shown). Specifically, a plurality of rollers having a predetermined interval may be provided between the first side plate 351 and the second side plate 352, and the plurality of rollers may be rotated. When the plurality of rollers rotate in the conveying direction, the carrier 35 can convey the object 2 to be conveyed placed on the plurality of rollers in the conveying direction. That is, the object 2 to be conveyed located at the upstream end 211 of the conveying mechanism 21 may be conveyed to the downstream end 212 in the conveying direction by a plurality of roller shafts using a roller conveying method. In addition, a plurality of rollers may form the first conveying surface S1.

In some examples, the first side plate 351, the second side plate 352, and the fixed rollers connecting the first side plate 351 and the second side plate 352 may be formed in a frame structure to support the conveyor belt or the plurality of rollers. In other words, a conveyor belt or a plurality of rollers may be disposed between the first and second side plates 351, 352.

In some examples, the extending direction of the carriers 35 may be a conveying direction.

In some examples, the spacing between the first side plate 351 and the second side plate 352 is adjustable. In this case, for example, when it is necessary to transport a larger volume of the object 2 to be transported, the conveying mechanism 21 may be adapted to transport a larger volume of the object 2 to be transported by enlarging the interval between the first side plate 351 and the second side plate 352.

In some examples, the transfer mechanism 21 may include a first guide portion 354 and a second guide portion 355 that are oppositely disposed and have a predetermined interval.

In some examples, the first guide portion 354 and the second guide portion 355 may be disposed in parallel above the first carrying plane S1. The object 2 to be conveyed can be placed in a conveying section formed between the first conveying surface S1, the first guide portion 354, and the second guide portion 355 and conveyed. In other words, the carrier 35, the first guiding portion 354 and the second guiding portion 355 cooperate to form a conveying section. When the object 2 is carried in the carrying section, the first guide portion 354 and the second guide portion 355 can limit and guide the object 2 to prevent the object 2 from sliding off from both sides of the first carrying surface S1, and can facilitate the object 2 to be carried to leave the first carrying surface S1 from a predetermined position.

In some examples, the first guide portion 354 and the second guide portion 355 may be on both sides of the carrier 35 in a relatively movable manner. For example, when the object 2 to be conveyed having a large width is conveyed, the first guide portion 354 and the second guide portion 355 may be moved relatively away from each other, so that the width of the conveying section is increased to be adapted to the object 2 having a large width.

In some examples, the object 2 to be conveyed may be conveyed along the conveying direction through the first conveying surface S1 along a predetermined route within the conveying section. In some examples, the predetermined route may be a central axis of the first carrying surface S1. When the object 2 to be conveyed deviates from the predetermined path, for example, when the object 2 to be conveyed is located in the conveying section and is close to the first guide portion 354 (i.e., the object 2 to be conveyed deviates toward the first guide portion 354), the first guide portion 354 may move to the direction close to the second guide portion 355 by a predetermined distance, so that the object 2 to be conveyed is located on the axis of the first conveying surface S1 to be conveyed.

In other examples, when the object 2 to be conveyed with a smaller volume needs to be conveyed, the object 2 to be conveyed can be moved away from the first conveying surface S1 from a predetermined position by reducing the distance between the first guide portion 354 and the second guide portion 355.

In some examples, both ends of the first guide portion 354 and the second guide portion 355 are outwardly arc-shaped. In this case, the object 2 to be conveyed can be guided to the conveying section between the first guide portion 354 and the second guide portion 355 along the ends of the arc-shaped first guide portion 354 and the second guide portion 355.

In some examples, the handling device 20 may further include an extension handling mechanism, and a telescoping connection (not shown) connecting the extension handling mechanism and the transport mechanism. The extension conveyance mechanism may have a fifth conveyance face.

In some examples, the extension handling mechanism may have an extended mode. When the extension conveyance mechanism is in the extension mode, the extension conveyance mechanism may be extended in a direction opposite to the conveyance direction (i.e., the C1 direction shown in the embodiment of fig. 1), and the fifth conveyance face is continuous with the first conveyance face S1 to convey the object 2 to be conveyed.

In some examples, the extension handling mechanism may have a retracted mode. When the extension conveying mechanism is in the retraction mode, the extension conveying mechanism can be retracted to the lower side of the conveying mechanism 21 along the conveying direction, and the fifth conveying surface is located below the first conveying surface S1 and does not affect the process of conveying the object 2 to be conveyed by the first conveying surface S1.

Fig. 3 is a partial schematic view showing a handling device 20 according to an example of the present invention. Fig. 4 is a partial sectional view showing the carrier device 20 according to the example of the utility model. Fig. 3 and 4 show the structure of the connecting device 40 and the driving mechanism 23 by omitting a part of the components that shield the connecting device 40 and the driving mechanism 23.

In some examples, the handling device 20 may include a connection substrate 41 (see fig. 3 and 4) provided to the base 200 and configured to be rotatable in the left-right direction.

In some examples, the handling device 20 may include a first connection mechanism 42 (see fig. 3 and 4). In some examples, the first connection mechanism 42 may be used to connect the transfer mechanism 21 with the connection substrate 41. In other examples, the first connection mechanism 42 can be used to connect the transport mechanism 21 with the base station 200.

Hereinafter, the first connection mechanism 42 is described as an example for connecting the transfer mechanism 21 and the connection substrate 41, and the first connection mechanism 42 for connecting the transfer mechanism 21 and the base 200 may be identical to the transfer mechanism 21 for connecting the transfer mechanism 21 and the connection substrate 41.

In some examples, the connection substrate 41 may be connected 201 with the load-bearing table 201 through the rotation member 411. The rotating member 411 may have a circular ring shape (see fig. 3 and 4). For example, the rotating member 411 may be a bearing. The connection substrate 41 may rotate in the left-right direction (i.e., the direction indicated by D3 or D4 in the embodiment shown in fig. 1) about the rotating member 411.

In some examples, the first connecting mechanism 42 may have a first shaft 421 and a second shaft 422 parallel to the first carrying surface S1 and orthogonal to the carrying direction, and a first connecting portion 423 (see fig. 3 and 4) connected to the first shaft 421 and the second shaft 422 and configured to be rotatable about the first shaft 421 and/or the second shaft 422. The first shaft 421 is provided on the carrier 35, and the second shaft 422 is provided on the connection substrate 41.

In some examples, the first shaft 421 may be disposed at the downstream end 212 of the transfer mechanism 21 (see fig. 3). In other examples, the first shaft 421 may be disposed between the upstream end 211 and the downstream end 212 of the transfer mechanism 21. For example, the first shaft 421 may be disposed between the upstream end 211 and the downstream end 212 of the transfer mechanism 21 and near the downstream end 212.

In some examples, the first connecting mechanism 42 may have a third axis 424 parallel to the first conveying surface S1 and orthogonal to the conveying direction, and a third connecting portion 425 connected to the third axis 424 and configured to be rotatable about the third axis 424 (see fig. 4).

In some examples, the connection device 40 may further include a second connection mechanism 43. Both ends of the second connecting mechanism 43 are fixed to the downstream end 212 of the transport mechanism 21 and the base 200, respectively (see fig. 2, 3, and 4).

In some examples, the second connection mechanism 43 may include a plurality of rollers. The plurality of rollers are connected in a scissor-like fashion such that the second connecting mechanism 43 is of a telescopic and bendable configuration (see fig. 3 and 4). In this case, when the driving mechanism 23 drives the transfer mechanism 21 to move, the end of the second link mechanism 43 connected to the base 200 is not moved, and the end of the second link mechanism 43 connected to the transfer mechanism 21 moves following the movement of the transfer mechanism 21.

In some examples, the second connecting mechanism 43 may have a second carrying face S2 (see fig. 3 and 4). For example, a plurality of rollers may cooperate to form the second conveying surface S2. The object 2 to be conveyed can be conveyed via the first conveying surface S1 of the carrier 35 and the second conveying surface S2 of the second link mechanism 43.

In some examples, the downstream end 212 of the transport mechanism 21 may be higher than a side of the load bearing table 201 that is connected to the downstream end 212 of the transport mechanism 21 by the second connection mechanism 43. In this case, the second conveyance surface S2 assumes a downwardly inclined posture (see fig. 3 and 4), and the object 2 to be conveyed can naturally move downward by gravity when positioned on the second conveyance surface S2.

In some examples, the end of the second connecting mechanism 43 connected to the base 200 may have at least two rollers, and the two rollers are disposed in parallel and horizontally. The two roller shafts of the second connecting mechanism 43 at the end connected to the base 200 can cooperate to form a buffer platform having a third conveyance surface S3 (see fig. 3 and 4).

In some examples, the third handling face S3 may be continuous with the second handling face S2. The object 2 to be conveyed can be conveyed through the first conveying surface S1, the second conveying surface S2, and the third conveying surface S3. In this case, the third conveying surface S3 can play a role of buffering to reduce the downward sliding speed of the object 2 to be conveyed, so that the object 2 to be conveyed can be smoothly separated from the third conveying surface S3.

In some examples, the buffer platform may include a rotatable drive roller. When the driving roller rotates along the conveying direction, the object 2 to be conveyed on the buffering platform can be conveyed along the conveying direction.

In some examples, the drive mechanism 23 may include a first drive portion 28 (see fig. 3). The first driving part 28 may be configured to drive the conveying mechanism 21 to move in the up-down direction (i.e., the direction indicated by D5 or D6 in the embodiment shown in fig. 1).

In some examples, the first driving part 28 may include a first driving motor 281 and a first driving shaft 282 driven and rotatable by the first driving motor 281. The first drive shaft 282 may be curved (see fig. 3).

In some examples, the first drive shaft 282 may be rotatably connected with the third connection 425 (see fig. 3). The first driving motor 281 drives the first driving shaft 282 to rotate so as to drive the third connecting portion 425 to move in the up-and-down direction, so that the conveying mechanism 21 rotates in the up-and-down direction around the first shaft 421.

In some examples, when the first driving part 28 drives the transfer mechanism 21, the transfer mechanism 21 may rotate in the up-down direction about the first shaft 421.

In some examples, the first driving part 28 may be provided to the connection substrate 41 (see fig. 3). In this case, when the connection substrate 41 rotates in the left-right direction, the first driving part 28 may rotate in the left-right direction along with the connection substrate 41. In this case, when the transfer mechanism 21 is rotated in the left-right direction by the connection substrate 41, the first driving unit 28 can drive the transfer mechanism 21 to move in the up-down direction without adjusting the angle.

In other examples, the first driving part 28 may be provided to the base 200.

In some examples, the drive mechanism 23 may include a second drive portion 29 (see fig. 3). The second driving part 29 may be configured to drive the transport mechanism 21 to move in the front-rear direction (i.e., the direction indicated by D1 or D2 in the embodiment shown in fig. 1).

In some examples, the second drive 29 may include a second drive motor 291 and a second drive shaft 292 driven and retractable by the second drive motor 291.

In some examples, the second drive shaft 292 may be rotatably coupled with the first coupling portion 423. In some examples, the second driving motor 291 may drive the second driving shaft 292 to extend and retract to rotate the first connection portion 423 around the second shaft 422 in the front-back direction, so that the transmission mechanism 21 can rotate around the second shaft 422 in the front-back direction. In other words, the second driving portion 29 can drive the transport mechanism 21 to rotate in the front-rear direction about the second shaft 422.

In some examples, the second driving part 29 may be connected with the connection substrate 41. When the connection substrate 41 is rotated in the left-right direction, the second driving part 29 may be rotated in the left-right direction along with the connection substrate 41.

In other examples, the first driving part 28 may be provided to the base 200.

In some examples, the drive mechanism 23 may include a third drive portion 30 (see fig. 4). The third driving part 30 may be configured to drive the conveying mechanism 21 to move in the left-right direction (i.e., the direction indicated by D3 or D4 in the embodiment shown in fig. 1).

In some examples, the third driving part 30 may drive the connection substrate 41 to rotate in the left and right direction. In some examples, the connection substrate 41 may have a transmission gear 412, and the transmission gear 412 may be disposed in an inner space of the rotation member 411 (see fig. 4). In some examples, the drive gear 412 may have a semi-circular shape, or a fully circular shape. Thereby, the rotation of the connection substrate 41 can be facilitated.

In some examples, the third driving part 30 has a third driving motor 301 and a brake gear 302. The brake gear 302 can be engaged with the drive gear 412 (see fig. 4). In this case, when the third driving motor 301 drives the stopper gear 302 to rotate, the transmission gear 412 rotates to drive the connection substrate 41 to rotate in the left-right direction about the rotation member 411 to rotate the conveyance mechanism 21 in the left-right direction. In other words, the third driving portion 30 can drive the conveying mechanism 21 to rotate in the left-right direction about the rotating member 411.

In some examples, the drive mechanism 23 may include a fourth drive portion (not shown). The fourth driving part may be configured to drive the base 200 to move.

In the embodiments shown in fig. 5, 6, 7, 8 and 9, the attitude of a part of the carrying device 20 is explained, but other attitudes are not described. For example, the transfer mechanism 21 may move forward or backward in the horizontal direction.

Fig. 10 is a plan view showing the carrying device 20 according to the example of the present invention. Fig. 11 is a schematic view showing an attitude in which the carrier device 20 according to the example of the utility model is turned leftward. Fig. 12 is a schematic view showing an attitude in which the carrying device 20 according to the example of the present invention is rotated to the right. Fig. 10, 11, and 12 show different postures of the conveyance device 20 by omitting parts that partially block the conveyance device 20 and the connection device 40.

Hereinafter, the different postures of the conveyance device 20 in the top view will be described with reference to the top view of the conveyance device 20 shown in fig. 10. In the example shown in fig. 11, the conveyance mechanism 21 may be rotated to the left about the rotation member 411 by the driving of the third driving portion 30. In the example shown in fig. 12, the conveyance mechanism 21 can be rotated rightward about the rotating member 411 by the driving of the third driving portion 30.

In some examples, the handling device 20 may further include a pick-up mechanism 50 (see fig. 1 and 2) coupled to the upstream end 211 of the transfer mechanism 21. The pickup mechanism 50 may be used to pick up the object 2 to be conveyed to the upstream end 211 of the conveyance mechanism 21.

In some examples, the pick-up mechanism 50 may have a proximal end near the object 2 to be carried, a distal end distant from the object 2 to be carried and connected to the upstream end 211 of the conveying mechanism 21, and a pick-up portion (not shown) for picking up the object 2 to be carried. The pickup portion may include an adsorption member (not shown) for adsorbing the object 2 to be conveyed. In this case, the pickup portion may suck the object 2 to be conveyed by the suction member to pick up the object 2 to be conveyed.

In some examples, the suction member may be a vacuum chuck (not shown). The vacuum chuck may include a vacuum control valve, and the vacuum control valve may be configured to draw air between the vacuum chuck and the object 2 to be conveyed when the pickup part picks up the object 2 to be conveyed to form a negative pressure (not shown) between the vacuum chuck and the object 2 to be conveyed. In this case, when the suction member sucks the object 2 to be conveyed, the suction surface of the vacuum chuck abuts on the surface of the object 2 to be conveyed, and the vacuum control valve sucks air between the suction surface of the vacuum chuck and the surface of the object 2 to be conveyed to form a negative pressure, thereby sucking the suction member to the surface of the object 2 to be conveyed.

In some examples, when the object 2 is conveyed, the pickup portion may move in the direction of the proximal end of the object 2 to be conveyed to pick up the object 2 to be conveyed, and the object 2 to be conveyed may be conveyed from the proximal end of the pickup mechanism 50 toward the distal end to the upstream end 211 of the conveying mechanism 21.

In some examples, the pick-up mechanism 50 may have a fourth carrying face S4 (see fig. 2). In some examples, the object 2 to be conveyed may be conveyed sequentially via the four conveying surfaces S4, the first conveying surface S1, the second conveying surface S2, and the third conveying surface S3.

In some examples, the pick-up mechanism 50 may be rotatably coupled with the upstream end 211 of the transport mechanism 21. The pickup mechanism 50 is movable in the up-down direction and/or the left-right direction with respect to the conveyance mechanism 21. In this case, the proximal end of the pickup mechanism 50 can be brought close to the object 2 to be conveyed to pick up the object 2 by finely adjusting the position of the pickup mechanism 50, and the direction of the conveying mechanism 21 can be kept unchanged.

While the utility model has been described in detail in connection with the drawings and examples, it should be understood that the above description is not intended to limit the utility model in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the true spirit and scope of the utility model, and such modifications and variations are intended to be within the scope of the utility model.
