The shell-shaped dental appliance is used as a dental medical appliance for correcting tooth deformity, and does not affect the appearance of human teeth in the process of correcting compared with a wire-type dental appliance. In addition, the shell-shaped tooth appliance has no risk of stabbing the peripheral parts of the teeth of the human body, and is convenient for keeping the oral hygiene. As a result, shell-like dental appliances are increasingly receiving attention from dentists.

In the processing process of the shell-shaped dental appliance, a dental model needs to be prefabricated according to the dental characteristics of a human body. Then, the film is pressed on the dental model, and the part covered on the dental model after the film pressing is cut and pried, so that the finished product of the shell-shaped dental appliance can be obtained. Therefore, high quality diaphragms are important for making high quality shell-like dental appliances, and performance and cleanliness of the diaphragm production equipment are important factors affecting the quality of the diaphragms. At present, generally set up the protection casing on diaphragm production facility, protect and shelter from diaphragm production facility, ensure that diaphragm production facility does not receive external interference and normal operating to play certain dustproof effect.

Although the protective cover is used for covering the protective cover, the diaphragm production equipment still needs to be overhauled and maintained regularly, and generally, the openable window is opened during overhauling by arranging the openable window on the protective cover, and the window is closed after overhauling is finished. However, the window opening width and angle are limited, and the maintenance work is often limited by the window opening width and angle, so that the maintenance work is inconvenient to operate. Therefore, the field needs a new protective cover which can flexibly adjust the opening position and opening amplitude of the protective cover according to the needs, reduce the use difficulty of the protective cover and the maintenance difficulty of production equipment, and is convenient for overhauling and maintaining the membrane production equipment.

The first protection cover 310 is movably arranged on the two inner sliding rails 210 along the extending direction of the inner sliding rail 210; the second protection cover 320 is movably disposed on the two outer sliding rails 220 along the extending direction of the outer sliding rails 220. Specifically, the track 200 includes a pair of inner rails 210 and a pair of outer rails 220, the first protection cover 310 is disposed on the inner rails 210, the second protection cover 320 is disposed on the outer rails 220, and before the first protection cover 310 and the second protection cover 320 move together due to the positioning member 410 and the limiting member 420, the movement of the first protection cover 310 and the second protection cover 320 does not interfere; in addition, all the first protection covers 310 have the same width in the direction perpendicular to the inner slide rail 210, and all the second protection covers 320 have the same width in the direction perpendicular to the outer slide rail 220, which is beneficial to the standardized arrangement of the mobile protection device.

Further, the protective cover set 300 includes a plurality of first protective covers 310 and a plurality of second protective covers 320, and the first protective covers 310 and the second protective covers 320 are alternately arranged. Each of the first shields 310 includes opposite first and second ends, each of which is provided with a positioning member 410, and each of the second shields 320 is provided with a limiting member 420 at both ends. The positioning member 410 at the first end is located between the two limiting members 420 of the second shield 320 near the first end, and the positioning member 410 at the second end is located between the two limiting members 420 of the second shield 320 near the second end.

For example, two first shields 310 and two second shields 320 are taken as an example, and the second shields 320 can be moved to be sleeved outside the first shields. The first protective cover 310 and the second protective cover are alternately arranged, at this time, the first end of the first protective cover 310 extends into the second protective cover 320 adjacent to the first end, and the positioning element 410 on the first end of the first protective cover 310 is located between the two limiting elements 420 on the second protective cover 320; the second end of the first shield 310 extends into the second shield 320 adjacent to the second end, and the positioning member 410 on the second end of the first shield 310 is located between two limiting members 420 on the second shield 320. The other first shield 310 may be disposed at an end of the first second shield 320 away from the first shield 310, or disposed at an end of the second shield 320 away from the first shield 310, which is not particularly limited herein. Thus, when it is desired to open the first shield 310 or the second shield 320 at the end of the shield group 300, the first shield 310 or the second shield 320 may be directly pushed; when the first shield 310 positioned in the middle of the shield set 300 needs to be opened, the second shield 320 positioned at the end of the shield set 300 can be pushed to move towards the first shield 310 positioned at the other end of the shield set 300, after the second shield 320 positioned at the end of the shield set 300 moves to be completely sleeved outside the first shield 310 positioned in the middle, the limiting piece 420 positioned on the second shield 320 positioned at the end pushes the positioning piece 410 positioned on the first shield 310 positioned in the middle so as to drive the first shield 310 to move together, and meanwhile, the end of the second shield 320 releases the end of the other second shield 320 and pushes the other second shield 320 to synchronously move until the other second shield 320 is sleeved outside the first shield 310 positioned at the end of the shield set 300, and at the moment, the parts of the production equipment originally covered by the second shield 320 positioned at the end of the shield set 300 and the first shield 310 adjacent to the second shield 320 are exposed; if the second shield 320 located at the middle of the shield set 300 needs to be opened, the first shield 310 located at the end of the shield set 300 may be pushed to move toward the other end of the shield set 300.

It will be appreciated that in the case where a pair of inner slide rails 210 and a pair of outer slide rails 220 are provided, all of the first shields 310 of the shield set 300 are provided on the inner slide rails 210 and all of the second shields 320 of the shield set 300 are provided on the outer slide rails 220.

Referring to fig. 1 again, in this embodiment, in order to further improve the convenience of using the mobile guard, a handle 330 may be provided on each guard located at the end of the guard set 300 in all the guard sets 300, and when the guard is opened or closed, an operator may push or pull the guard through the handle 330.

In a preferred embodiment, the protective cover set 300 includes a first protective cover 310 and a second protective cover 320. At this time, the first protective cover 310 can be directly pushed to expose the production equipment covered by the first protective cover 310, and other protective covers are not required to be pushed at the same time, so that the operation can be simplified.

More preferably, the lengths of the first and second shields 310 and 320 in the extending direction of the rail 200 may be set to be equal. In this way, the opened area can be maximized, i.e., half of the covered area, when the first shield 310 or the second shield 320 is opened, and the second shield 320 is pushed to be completely opened after the first shield 310 is opened and the maintenance of the production equipment originally covered by the first shield 310 is completed, so that the maintenance of the entire equipment can be completed.

Referring to fig. 4 and 5, the mobile protection device has three protection cover sets 300. Fig. 4 shows pushing a second shield cap 320, thereby opening the second shield cap 320 to expose the production equipment covered by the second shield cap 320; fig. 5 shows the two second shields 320 being pushed away from each other to the extreme position, which is the maximum extent to which the mobile guard can be opened.

In this embodiment, the positioning member 410 is a baffle, and the limiting member 420 is a protrusion. The baffle protrudes from the outer surface of the first protection cover 310, and the protrusion on the second protection cover 320 protrudes from the inner surface of the second protection cover 320. Specifically, when the operator pushes the first protection cover 310, the baffle moves along with the first protection cover 310, and when the baffle moves to be abutted against any one of the limiting pieces 420 (i.e. the protrusions) on the adjacent second protection cover 320, and continues to push the first protection cover 310, the baffle pushes the protrusions to move, so as to drive the second protection cover 320 to move; while the movement of the first shield 310 does not affect the second shield 320 when the shutter and the protrusion are not in contact. Alternatively, based on the same principle, the positioning element 410 and the limiting element 420 may be both provided as a stop, where the positioning element 410 (i.e. the stop) protrudes from the outer surface of the first protection cover 310, and the limiting element 420 (i.e. the stop) on the second protection cover 320 protrudes from the inner surface of the second protection cover 320. The positioning element 410 and the limiting element 420 can select a specific setting method and structure according to actual requirements, so that the setting of the mobile protection device is more flexible.

Thus, when the production equipment needs to be covered by the protective cover, the connecting structure 500 can connect two adjacent protective cover groups 300, eliminate the gap between the two protective cover groups and ensure that the production equipment is completely covered; when multiple sets of protective cover sets 300 need to be opened to expose a large area of production equipment, since two adjacent protective cover sets 300 are connected via the connection structure 500, one protective cover set 300 can be pushed or pulled to drive the other protective cover set 300 to move together; when it is desired to independently move one of the protective cover sets 300, the connection of the connection structure 500 may be released so that both adjacent protective cover sets 300 may be independently moved with respect to each other.

Specifically, in the present embodiment, the connection structure 500 includes a first connection member 510 and a second connection member 520, where the first connection member 510 is configured to detachably connect the second connection member 520. One of any adjacent two shield groups 300 is provided with a first connection member 510 and the other is provided with a second connection member 520, and any adjacent two shield groups 300 are detachably connected via the first connection member 510 and the second connection member 520.

For example, a plurality of first connectors 510 and a plurality of second connectors 520 are disposed on one protective cover set 300, and the first connectors 510 and the second connectors 520 are alternately disposed from bottom to top, so that adjacent protective cover sets 300 are also disposed with the same number of first connectors 510 and second connectors 520, and the second connectors 520 and the first connectors 510 are alternately disposed from bottom to top. In addition, when a plurality of first connectors 510 and a plurality of second connectors 520 are provided on one shield group 300, the first connectors 510 and the second connectors 520 may not be alternately provided.

Further, a first connector 510 and/or a second connector 520 may be provided at an end of the protective cover set 300.

It should be noted that, when the number of the protective cover sets 300 is not less than three, for example, the protective cover sets 300 are taken as three as an example, the first connection members 510 and/or the second connection members 520 are provided at both ends of the protective cover set 300 positioned in the middle, and the first connection members 510 and/or the second connection members 520 at both ends of the protective cover set 300 are detachably connected with the first connection members 510 and/or the second connection members 520 of the other protective cover sets 300 positioned at both sides of the protective cover set 300, respectively.

It should be noted that, since each protective cover set 300 includes at least one first protective cover 310 and at least one second protective cover 320, when the second protective cover 320 can be sleeved outside the first protective cover 310, the height and width of the second protective cover 320 on the track 200 are greater than those of the first protective cover 310. Therefore, in order to facilitate connection between the different shield groups 300, the manufacturing cost of the moving guard can be reduced, and the shields adjacent to each other on two adjacent shield groups 300 can be both provided as the first shield 310 or the second shield 320. For example, the first shield 310 of one shield group 300 is provided with the first connector 510, and the shield of the adjacent shield group 300 provided with the second connector 520 for connecting the first connector 510 is the first shield 310, so that the shields of the adjacent two shield groups 300 are the same in size for connecting, and the butt joint of the first connector 510 and the second connector 520 is facilitated.

In other possible embodiments, the shields used for the connection between two adjacent shield groups 300 may also be different, such as one shield being a first shield 310 and the other shield being a second shield 320. At this time, since the heights and widths of the first and second shields 310 and 320 are different, the setting positions of the first and second connection members 510 and 520 need to be adaptively adjusted.

In this embodiment, the connection structure 500 may be a quick lock, where the first connection member 510 is a clamping member and the second connection member 520 is a fixing member. For example, the first connection member 510 is fixed to the end of the first shield 310 of one shield group 300, and the second connection member 520 is fixed to the end of the first shield 310 of the adjacent shield group 300, wherein the first connection member 510 extends toward the adjacent shield group 300 and is provided with a first protrusion structure 511 at the end, and the second connection member 520 has a groove-like receiving structure 521 (which may be a groove), and a second protrusion structure 522 is provided in the receiving structure 521, and when the first protrusion structure 511 of the first connection member 510 extends into the receiving structure 521 of the second connection member 520 and is clamped with the second protrusion structure 522, the connection between the first connection member 510 and the second connection member 520 is achieved, so that the connection between the adjacent two shield groups 300 can be quickly achieved, or the connection can be quickly released. Alternatively, either one of the first and second connectors 510 and 520 may have a resilient structure so that the first protrusion structure 511 presses the second protrusion structure 522 to cross the second protrusion structure 522 and is caught with the second protrusion structure 522.

It can be appreciated that the second protruding structure 522 may be a plurality of protruding structures arranged at intervals, or may be an integral annular protruding structure; in addition, since the quick latches may be connected when the adjacent two shield groups 300 are close to each other to a certain extent, and may be separated when the adjacent two shield groups 300 are separated from each other, the quick latches may be disposed on the outer wall of the shield as well as the inner wall of the shield.

Referring to fig. 9, in other embodiments, the connection structure may be configured like a latch. For example, the fixing member 530 may have an omega shape, and the U-shaped bar 540 may be movably disposed on the fixing member 530, wherein the two fixing portions 531 of the fixing member 530 may be fixed to the outer wall of the shield by screw fixing, rivet fixing, welding or other means, and the arched portion 532 of the fixing member 530 is arched away from the outer wall of the shield and forms a through hole, the two fixing portions 531 are disposed at opposite sides of the arched portion 532, respectively, the U-shaped bar 540 is disposed to be movable with respect to the shield along the extending direction of the rail 200, that is, the main portion 541 of the U-shaped bar 540 passes through the through hole formed by the arched portion 532 and is movable with respect to the arched portion 532, and the U-shaped bar 540 may be rotatable with the axis of the main portion 541 as a rotation axis, and the connection structure may further include a simple boss/stopper 550. When it is desired to connect two adjacent shield sets 300, the U-shaped bar 540 is moved such that the bent portion 542 at one end of the U-shaped bar 540 rides over the protrusion/stopper 550, and then the U-shaped bar 540 is rotated downward such that the bent portion 542 at one end of the U-shaped bar 540 catches the protrusion/stopper 550, thereby achieving connection of two adjacent shield sets 300. In a natural state, the U-shaped rod 540 is under the gravity action and does not automatically rotate upwards, and the situation that the U-shaped rod 540 is separated from the bulge/stop 550 does not occur.

It will be appreciated that the combination of the securing member 530 and the U-shaped bar 540 may be considered a first attachment member and the protrusion/stop 550 may be considered a second attachment member with a latch-like attachment structure generally provided on the outer wall of the enclosure for convenient operation by an operator.

Further, a locking structure may be provided on the protective cover provided with the protrusion/stopper 550, so as to fix the bent portion 542 of the U-shaped bar 540, so that the U-shaped bar 540 can only rotate when operated manually, thereby further preventing the U-shaped bar 540 from accidentally disengaging from the protrusion/stopper 550 and improving the stability of the connection between two adjacent protective cover sets 300. It will be appreciated that when the locking structure is provided to prevent rotation of the U-shaped bar 540 without human intervention, the position of the boss/stop 550 may also be adjusted such that the U-shaped bar 540 rotates upwardly to retain the boss/stop 550; or two bulges/stop blocks 550 are arranged at the same time, a groove is formed between the two bulges/stop blocks 550, and when the U-shaped rod 540 moves, the U-shaped rod 540 rotates to clamp any bulge/stop block 550 after passing through the groove.

In another possible embodiment, the first connection member 510 is rotatably fixed to the shield cover with respect to the outer surface of the shield cover, the free end of the first connection member 510 may be close to or far from the outer surface of the shield cover when the first connection member 510 is rotated, and the second connection member 520 is fixed to the shield cover in the adjacent shield cover group 300, and the first connection member 510 connects the second connection member 520 when the first connection member 510 is rotated in a direction of making the free end close to the outer surface of the shield cover, thereby connecting the adjacent two shield cover groups 300 together; when the first link 510 is rotated in a direction to move the free end away from the outer surface of the shield, the first link 510 and the second link 520 are disconnected. It should be understood that in this arrangement, the first connector 510 and the second connector 520 may be connected by a hanging connection, a clamping connection, or the like, which is not specifically described herein.

In other embodiments, the connection structure may be a rotating buckle similar to a hook, and the specific arrangement manner may be selected according to practical situations, which is not limited in particular in the embodiments of the present utility model.

In this embodiment, the production facility is a conveyor belt, and the conveyor belt is covered when the first shield 310 and the second shield 320 in all the shield groups 300 are completely closed. When all the shields in all the shield groups 300 are closed, the entire conveyor is covered, so that foreign matters such as dust can be prevented from falling onto the conveyor, and products transported on the conveyor can be prevented from being contaminated. It will be appreciated that in practice the production equipment is not limited to conveyor belts.
