Fig. 1 and 4 are schematic structural views of a door apparatus according to an embodiment of the present invention, fig. 2 and 3 are sectional views of the door apparatus shown in fig. 1 taken along different sectional planes, fig. 5 is a sectional view of the door apparatus shown in fig. 4, and fig. 6 is a partially enlarged schematic view of fig. 5. As shown in fig. 1 to 6, the door apparatus includes a door frame structure 1000, a door assembly 2000, and a driving part 3000. The door assembly 2000 includes a guide groove seat 2100, a joint portion 2200 and a door body 2300, wherein the guide groove seat 2100 is connected to the door frame assembly 1000 and can reciprocate along a first direction, a guide groove 2110 is formed in the guide groove seat 2100, the guide groove 2110 includes an inclined section 2111, and an extending direction of the inclined section 2111 intersects with both the first direction and a second direction. The second direction is perpendicular to the first direction. The engaging portion 2200 is partially movably disposed in the guiding groove 2110, and the engaging portion 2200 is further connected to the door 2300. The driving part 3000 is provided on the door frame structure 1000 and is coupled to the door assembly 2000. The driving portion 3000 is configured to drive the door assembly 2000 to reciprocate integrally along the first direction, and the driving portion is further configured to drive the engaging portion 2200 to reciprocate along the guide slot 2110 relative to the guide slot base 2100, wherein when the engaging portion 2200 reciprocates along the inclined portion 2111 relative to the guide slot base 2100, the driving portion 3000 drives the door body 2300 to reciprocate at least along the second direction. Here, the driving part 3000 drives the door assembly 2000 to reciprocate integrally in the first direction refers to a case where all the components of the door assembly 2000 reciprocate in the first direction due to the operation of the driving part 3000. When the door assembly 2000 integrally reciprocates in the first direction, the door body 2300 reciprocates in the first direction.

The door 2300 is used for plugging an opening in a wall. The utility model provides a door gear utilizes same drive division 3000 to order about the door body 2300 carries out the motion of two directions (follow promptly the reciprocating motion of first direction and edge the reciprocating motion of second direction), can reduce the power that door assembly 2000 consumed at the operation in-process reduces the running cost. In addition, such a configuration is also beneficial to reducing the volume of the door device, as shown in fig. 7, when the wall is a partition wall 101 located inside a working chamber 110, that is, when the door body 2300 is used to plug the opening on the partition wall 101 so as to divide the working chamber 110 into two sub-chambers 111 which are isolated from each other, the occupied volume of the door device in the working chamber 110 is smaller, which is beneficial to reducing the volume of the working chamber 110, and further, when the working chamber 110 is vacuumized, the vacuumizing speed can be increased, and the efficiency is improved.

The inclined portion 2111 of the guide groove 2110 intersects both the first direction and the second direction, so that when the engaging portion 2200 moves relative to the guide groove housing 2100 along the inclined portion 2111, the engaging portion 2200 moves in the first direction and the second direction relative to the guide groove housing 2100 simultaneously. Therefore, when the engaging portion 2200 moves relative to the chute seat 2100 along the inclined section 2111, the door 2300 is allowed to move in the second direction at least along with the engaging portion 2200.

In the embodiment of the present invention, when the driving portion 3000 drives the door assembly 2000 to move integrally toward the positive direction of the first direction, and the driving portion 3000 drives the engaging portion 2200 to move along the inclined section 2111 relative to the guiding slot seat 2200 to drive the door 2300 to move toward the positive direction of the second direction, the door 2300 can block the opening. On the premise that the door 2300 blocks the opening, when the driving portion 3000 drives the engaging portion 2200 to move along the inclined section 2111 relative to the guide slot seat 2100 to drive the door 2300 to move towards the negative direction of the second direction, and the driving portion 3000 drives the door assembly 2000 to move integrally towards the negative direction of the first direction, the door 2300 can release the blocking of the opening.

Specifically, during the process of blocking the opening, the driving portion 3000 drives the door assembly 2000 to move integrally toward the positive direction of the first direction, then the driving portion 3000 drives the engaging portion 2200 to move along the guide slot 2110 relative to the guide slot seat 2100, and during the process of moving the engaging portion 2200 along the inclined section 2111 relative to the guide slot seat 2100, the engaging portion 2200 is used to drive the door body 2300 to move toward the positive direction of the second direction. In the process of releasing the blocking of the opening, the driving portion 3000 drives the engaging portion 2200 to move along the guide groove 2110 relative to the guide groove seat 2100, and in the process of moving the engaging portion 2200 along the inclined section 2111 relative to the guide groove seat 2100, the engaging portion 2200 is used to drive the door 2300 to move at least in the negative direction of the second direction. The door assembly 2000 is then driven by the driving portion 3000 to move in a negative direction of the first direction as a whole.

Further, with continued reference to fig. 1 and 4, the door device further includes a limiting portion 4000, and the limiting portion 4000 is configured to limit a maximum movement distance of the door assembly 2000 moving integrally toward the positive direction of the first direction. In the process of blocking the opening, after the door assembly 2000 integrally moves towards the positive direction of the first direction to the maximum movement distance, the driving portion 3000 drives the engaging portion 2200 to move along the guide groove 2110 relative to the guide groove seat 2100, so that the door body 2300 moves towards the positive direction of the second direction.

Taking the orientation shown in fig. 1 to 6 as an example, the first direction may be a Z-axis extending direction, the positive direction of the first direction is a positive Z-axis direction (i.e., the direction of an arrow on the Z-axis), and the negative direction of the first direction is a negative Z-axis direction (i.e., the direction of an arrow on the Z-axis is opposite). The second direction may be an extending direction of the X axis, the positive direction of the second direction is a positive direction of the X axis (i.e., pointing direction of an arrow on the X axis), and the negative direction of the second direction is a negative direction of the X axis (i.e., opposite direction of pointing direction of an arrow on the X axis). In this document, it is described by way of example that the Z axis extends in the vertical direction, the arrow thereon points downward, the X axis extends in the front-rear direction, and the arrow thereon points forward, that is, the "vertical direction" mentioned later refers to the "first direction", the "downward" refers to the "positive direction toward the first direction", the "upward" refers to the "negative direction toward the first direction", the "front-rear direction" refers to the "second direction", the "forward" refers to the "positive direction toward the second direction", and the "rearward" refers to the "negative direction toward the second direction". It should be noted that such orientation descriptions are defined only for the convenience of description, and should not be construed as limiting the present invention.

Next, alternative structures of the gate device will be described in detail herein by way of example.

< example one >

Fig. 1 shows an overall structural schematic diagram of a gate device provided in this embodiment. As shown in fig. 1, the door frame assembly 1000 preferably includes a base plate 1100, a coupling seat 1200, and a guide mechanism 1300. The substrate 1100 extends in a third direction. The number of the connection seats 1200 is two, the two connection seats 1200 are respectively disposed on two opposite sides of the substrate 1100 in the third direction, and each connection seat 1200 extends along the first direction. Each of the connecting seats 1200 is provided with one of the guiding mechanisms 1300, and the two guiding mechanisms 1300 are symmetrically arranged and extend along the first direction. Optionally, the guide mechanism 1300 includes a guide rail or a sliding slot. The third direction is perpendicular to the first direction and the second direction. That is, the third direction is an extending direction of the Y axis in fig. 1 to 3, and herein, is a left-right direction.

The number of the guide groove seats 2100 is two, and the two guide groove seats 2100 are located on two opposite sides of the door body 2300 in the left-right direction and are respectively connected with the corresponding guide mechanisms 1300. That is, the guide groove holder 2100 positioned at the left side of the door body 2300 is connected to the guide mechanism 1300 of the connection holder 1200 positioned at the left side of the substrate 1100, and the guide groove holder 2100 positioned at the right side of the door body 2300 is connected to the guide mechanism 1300 of the connection holder 1200 positioned at the right side of the substrate 1100.

Optionally, if the guiding mechanism 1300 includes a sliding slot, referring to fig. 2, in a preferred implementation, the door assembly 2000 further includes a fourth rolling member 2400, and the fourth rolling member 2400 is connected to the guide slot seat 2100, and specifically, the door assembly 2000 further includes a fourth central shaft 2500, and the fourth central shaft 2500 is connected to the guide slot seat 2100 and extends in a left-right direction (i.e., the third direction). The fourth rolling element 2400 is sleeved on the fourth central axis 2500 and can rotate around the fourth central axis 2500. The fourth rolling element 2400 is arranged in the gate. With this configuration, when the door assembly 2000 integrally reciprocates in the vertical direction, the friction between the door assembly 2000 and the guide mechanism 1300 can be made rolling friction, reducing the friction force, reducing the wear, and improving the smoothness of the movement. The fourth rolling element 2400 is, for example, a bearing.

Referring back to fig. 1, in this embodiment, the number of the engaging portions 2200 is at least two, and at least two of the engaging portions 2200 are respectively located on two opposite sides of the door 2300 in the left-right direction and connect the door 2300 with the corresponding guide slot seat 2100. Alternatively, the number of the joint portions 2200 is four, and each two joint portions 2200 are disposed on the same side of the door body 2300, that is, the left side of the door body 2300 is connected to the left guide slot holder 2100 through the two joint portions 2200, and the right side of the door body 2300 is connected to the right guide slot holder 2100 through the two joint portions 2200.

Preferably, referring to fig. 1 in combination with fig. 2, the engaging portion 2200 includes a connecting block 2210 and a first rolling member 2220, wherein the connecting block 2210 is connected to the door body 2300. The first rolling member 2220 is coupled to the connection block 2210, and in particular, the engaging portion 2200 further includes a first central shaft 2230, the first central shaft 2230 is coupled to the connection block 2210 and extends in a left-right direction, and the first rolling member 2220 is fitted over the first central shaft 2230 and is rotatable about the first central shaft 2230. The first rolling member 2220 is also disposed in the guide groove 2110 and can move along the guide groove 2110. This configuration has the advantage that when the driving portion 3000 drives the engaging portion 2200 to move along the guide groove 2110 relative to the guide groove base 2100, the friction between the engaging portion 2200 and the guide groove base 2100 is rolling friction, thereby reducing friction, reducing wear, and improving smoothness of movement. The first rolling member 2220 may be a bearing.

The driving part 3000 is disposed on the substrate 1100. The output end of the driving part 3000 includes a telescopic bar 3010, that is, the driving part 3000 may include any one of a linear electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

In this embodiment, the driving portion 3000 is connected to the guide seat 2100. In detail, with continued reference to fig. 1, the driving portion 3000 includes a driving portion body 3100 and an engaging plate. The output end of the driving portion body 3100 is the telescopic rod 3010, that is, the driving portion body 3100 is any one of a linear electric cylinder, an air cylinder and a hydraulic cylinder. The coupling plate may be referred to as a first coupling plate 3200, the first coupling plate 3200 extends in a left-right direction, and the first coupling plate 3200 is coupled to both upper ends of the two chute holders 2100. The driving portion body 3100 is disposed above the first coupling plate 3200, and a lower end of the expansion link 3010 is connected to the first coupling plate 3200. Thus, when the retractable bar 3010 is extended, the retractable bar 3010 pushes the first joint plate 3200 to move downward (i.e., to move in the positive direction of the first direction), and drives the chute base 2100 to move downward, whereas when the retractable bar 3010 is shortened, the retractable bar 3010 pulls the first joint plate 3200 to move upward (i.e., to move in the negative direction of the first direction).

And the limit portion 4000 limits the maximum movement distance of the door assembly 2000 moving downward as a whole by limiting the maximum movement distance of the door body 2300 moving downward. Optionally, with continuing reference to fig. 1, the limiting portion 4000 includes a limiting plate 4100, a limiting seat 4200 and a second rolling element 4300, the limiting plate 4200 is disposed below the door body 2300, the limiting seat 4200 is disposed on the door body 2300, the second rolling element 4300 is disposed on the limiting seat 4200, specifically, the limiting portion 4000 further includes a second central axis 4400, the second central axis 4400 extends in the left-right direction, the second central axis 4400 is connected to the limiting seat 4200, and the second rolling element 4300 is sleeved on the second central axis 4400 and can rotate around the second central axis 4400. The second rolling member 4300 is configured to contact an upper end surface of the limit plate 4100, and roll on the limit plate 4100. The second rolling elements 4300 may be bearings. It can be understood that, the second rolling element 4400 is arranged, so that when the door body 2300 moves in the front-back direction, the friction inside the limiting portion 4000 is rolling friction, the friction force is reduced, the abrasion is reduced, and the smoothness of movement is improved.

The door device has an initial state and a working state, in the initial state, the second rolling member 4300 is located above the limit plate 4100, the door body 2300 does not block the opening, and in the working state, the door body 2300 blocks the opening. And, when the door assembly is in the initial state and before the door assembly 2000 is integrally moved downward to the maximum movement distance, the first rolling member 2220 is brought into contact with the lower end surface of the guide groove 2110.

The door device is switched from the initial state to the working state, so that the process of plugging the opening is as follows:

first, the driving portion body 3100 operates to extend the retractable bar 3010, push the first coupling plate 3200 to move downward, and further push the guide slot base 2100 to move downward by the first coupling plate 3200, and at the same time, the coupling portion 2200 and the door body 2300 also move downward. That is, the door assembly 2000 is integrally moved downward due to the operation of the driving part 3000.

When the door body 2300 moves downward until the fourth rolling member 4300 contacts the limit plate 4100, the movement distance of the downward movement of the door body 2300 reaches the maximum movement distance, so that the movement distance of the downward movement of the door assembly 2000 as a whole reaches the maximum movement distance.

Thereafter, the driving portion body 3100 continues to work, so that the telescopic rod 3010 continues to elongate, and pushes the first joint plate 3200 to continue to move downward. At this time, the door body 2300 and the engaging portion 2200 are kept relatively stationary in the vertical direction due to the restriction of the stopper portion 4000. Therefore, the guide groove holder 2100 moves downward relative to the engaging portion 2200 and the door body 2300, so that the first rolling member 2220 moves relative to the guide groove holder 2100 along the guide groove 2110 until the upper end surface of the guide groove holder 2100 contacts the first rolling member 2220. And during the process that the first rolling member 2220 moves along the inclined section 2111 relative to the guide slot seat 2100, due to the limitation of the guide mechanism 1300, the guide slot seat 2100 can only move in the downward direction, so that the engaging portion 2200 moves forward (i.e. the positive direction of the second direction), and drives the door body 2300 to move forward to close the opening.

The door device is switched from the working state to the initial state, so that the process of removing the blockage of the opening is as follows:

first, the driving portion body 3100 is operated to retract and shorten the retractable bar 3010, and pull the first joint plate 3200 to move upward (i.e. a negative direction of the first direction), so as to drive the guide slot base 2100 to move upward. At this time, due to the gravity, the door body 2300 is kept stationary in the vertical direction, and at the same time, the engaging portion 2200 is also kept stationary in the vertical direction, so that the engaging portion 2200 moves relative to the guide groove base 2100 along the guide groove 2110 until the first rolling member 2220 comes into contact with the lower end surface of the guide groove 2110. During the relative movement of the engaging portion 2200 along the inclined section 2111 and the guide slot seat 2100, the engaging portion 2200 also moves backward, and drives the door 2300 to move backward (i.e. the negative direction of the second direction).

Thereafter, the driving portion body 3100 continuously operates to continuously retract and shorten the retractable rod 3010, and pull the first engaging plate 3200 to move upward, so as to drive the guide slot seat 2100 to move upward, and drive the engaging portion 2200 and the door body 2300 to move upward through the guide slot seat 2100, so as to integrally move the door assembly 2000 upward. When the door device returns to the initial position, the driving portion body 3100 stops operating.

< example two >

Fig. 4 is a schematic view showing an overall structure of the gate device provided in the present embodiment, fig. 5 is a cross-sectional view of fig. 4, and fig. 6 is a partially enlarged schematic view of fig. 4. As shown in fig. 4 to 6, the present embodiment is different from the first embodiment in that the driving part 3000 is connected to the door assembly 2000 in a different manner.

Referring to fig. 4 to 6, in the present embodiment, the driving portion 3000 is connected to the door 2300. In detail, the driving unit 3000 includes a driving unit body 3100 and an engaging mechanism 3300. The driving unit body 3100 includes the extendable rod 3010, that is, the driving unit body 3100 may be any of a linear electric cylinder, an air cylinder, and a hydraulic cylinder. The joint mechanism 3300 includes a joint plate called as a second joint plate 3310, the second joint plate 3310 is disposed on the door 2300, and the joint plate 3310 is further formed with an accommodating groove (not labeled in the drawings) extending along a front-back direction (i.e., the second direction). The joint mechanism 3300 further includes a floating head 3320 and a holding portion 3330, and the floating head 3320 is movably disposed in the receiving groove and can move relative to the second joint plate 3310 in the front-rear direction. The floating head 3320 is connected with the lower end of the telescopic rod 3010 of the driving body 3100. The clamping part 3330 is connected to the floating head 3320 and includes a first clamping member 3331 and a second clamping member 3332, and the first clamping member 3331 and the second clamping member 3332 are respectively positioned at upper and lower sides of the second joint plate 3310, thereby enabling the connection of the floating head 3320 and the second joint plate 3310. When the floating head 3320 and the second joint plate 3310 make relative movement in the front-rear direction, the first holder 3331 and the second holder 3332 move in the front-rear direction on the second joint plate 3310.

Preferably, the first clamping member 3331 includes at least two third rolling members, and the at least two third rolling members of the first clamping member 3331 are respectively located at opposite sides of the floating head 3320 in the left-right direction. Similarly, the second clamping member 3332 may also include at least two third rolling members, and the at least two third rolling members of the second clamping member 3332 are respectively located at two opposite sides of the floating head 3320 in the left-right direction. It will be understood by those skilled in the art that the clamping portion 3330 further includes a third central shaft (not shown), which extends in the left-right direction and is connected to the floating head 3320, and the third rolling element is sleeved on the third central shaft and can rotate around the third central shaft. This provides an advantage in that when the first holder 3331 and the second holder 3332 move in the forward and backward directions on the second engagement plate 3310, the friction between the holder portion 3330 and the second engagement plate 3310 is rolling friction, reducing wear, and also improving smoothness of movement.

The present embodiment is further different from the first embodiment in that, in the process of switching the door apparatus from the initial state to the working state, the limit portion 4000 limits the maximum movement distance of the door assembly 2000 moving downward as a whole by limiting the maximum movement distance of the downward movement of the chute seat 2100. Optionally, the limiting portion 4000 includes a stopper, which is disposed on the door frame structure 1000, specifically, on the connecting seat 1200, and is located below the guide groove seat 2100 (i.e., on a side of the guide groove seat 2100 facing downward in the positive direction of the first direction). It is understood that the number of the stoppers is two, and the two stoppers are respectively disposed on the two connecting seats 1200 to respectively limit the maximum moving distance of the two guide groove seats 2100 moving downward.

In this embodiment, when the door assembly is in the initial state and before the door assembly 2000 moves downward to the maximum movement distance, the first rolling member 2220 is in contact with the upper end surface of the guide groove 2110.

Here, the process of switching the door device from the initial state to the working state to close the opening is as follows:

the driving part body 3100 is operated to extend the expansion bar 3010. The expansion link 3010 pushes the second joint plate 3310, the door 2300, and the joint portion 2200 downward through the clamping portion 3330. At the same time, the chute base 2100 also moves downward.

When the guide groove base 2100 moves until the lower end surface of the guide groove base 2100 abuts against the stopper, the movement distance of the downward movement of the guide groove base 2100 reaches the maximum movement distance, that is, the movement distance of the downward movement of the door assembly 2000 as a whole reaches the maximum movement distance.

Thereafter, the driving portion body 3100 continues to work, so that the extensible bar 3010 continues to extend. The extension bar 3010 pushes the second joint plate 3310, the door 2300, and the joint portion 2200 continuously downward by the clamping portion 3330. At this time, since the guide groove seat 2100 cannot move downward, the door body 2300 and the engaging portion 2200 move relative to the guide groove seat 2100 along the guide groove 2210 until the engaging portion 2200 contacts the lower end surface of the guide groove 2210. And during the relative movement of the engaging portion 2200 along the inclined section 2111 and the guide slot seat 2100, the engaging portion 2200 also drives the door body 2300 to move forward and block the opening. It can be understood that, during the process that the door body 2300 is moved forward by the engaging portion 2200, the second engaging plate 3310 and the floating head 3320 move relative to each other in the forward and backward direction, i.e., the second engaging plate 3310 moves forward relative to the floating head 3320.

The door device is switched from the working state to the initial state, so that the process of removing the blockage of the opening is as follows:

the driving part body 3100 works to retract and shorten the telescopic bar 3010. The telescopic rod 3010 drives the second joint plate 3310, the door body 2300 and the joint portion 2200 to move upward through the clamping portion 3330 until the first rolling member 2220 contacts with the upper end surface of the guide groove 2210. At this time, the chute holder 2100 is kept stationary in the vertical direction due to gravity, and thus the engaging portion 2200 moves upward along the guide groove 2110 with respect to the chute holder 2100 until the first rolling member 2220 comes into contact with the upper end surface of the guide groove 2210. During the relative movement of the engaging portion 2200 along the inclined section 2111 and the guide slot base 2100, the engaging portion 2200 also drives the door 2300 to move backward (i.e. the negative direction of the second direction), and at the same time, the second engaging plate 3310 moves backward relative to the floating head 3320.

Thereafter, the driving portion body 3100 continues to work, so that the telescopic rod 3010 continues to retract and shorten, and the first engaging plate 3200 is pulled to move upward by the clamping portion 3330, so as to drive the door body 2300 to move upward, and the first rolling member 2220 pushes the chute seat 2100 to move upward, so that the door assembly 2000 integrally moves upward. When the door device returns to the initial position, the driving portion body 3100 stops operating.

Further, the present invention also provides a production apparatus, as shown in fig. 7, the production apparatus includes a housing 100 and the door device as described above. The housing 100 includes a plurality of interconnected walls, at least one of which is provided with an opening. The door device is disposed on the housing 100, and the door 2300 selectively closes or releases the opening.

Still further, the wall includes a plurality of outer walls 102 and a partition wall 101, a working chamber 110 is formed by enclosing a plurality of outer walls 102, the partition wall 101 is disposed in the working chamber 110 and divides the working chamber 110 into two sub-chambers 111, and the partition wall is provided with the opening.

Although the present invention is disclosed above, it is not limited thereto. Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
