[0026] In the related art, in order to prevent the door body from being opened by mistake, a scheme of separately installing a door lock device on each door body of the oven is generally adopted. However, when the oven has a large number of door bodies, configuring an independent safety lock for each door not only increases the cost of the whole machine, but also reduces the efficiency of unlocking and locking operation. In view of the above problems, the present application provides a door lock device and a multi-door equipment, which can synchronously control the locking state of multiple door bodies through a single locking component, effectively reducing the number and cost of locks, and improving the efficiency of unlocking and locking operation.

[0027] The technical scheme of the embodiments of the present application is described in detail below with reference to the drawings.

[0031] The unlocking piece 1213 refers to an operating part for triggering the locking or unlocking of the locking assembly 121, for example, it can be a key or other structure similar to a key. The locking part is a part or structure matched (for example, clamped and matched) with the locking matching part to realize mechanical locking, specifically, a retractable lock tongue 1214 can be used to limit the movement of the locking matching part by clamping and limiting, wherein the locking matching part is connected with the plurality of locking execution pieces 122 for synchronously transmitting the locking or unlocking of the locking assembly 121 to the plurality of locking execution pieces 122, so as to realize the synchronous control of the plurality of locking execution pieces 122.

When the unlocking state is entered, the locking part and the locking matching part are unlocked, and the plurality of locking execution pieces 122 synchronously move to the position away from the door body 110 under the action of external force or a reset mechanism, so as to avoid hindering the opening and closing of the door body 110.

The linkage connection mechanism refers to a mechanical structure for transmitting a motion relationship, and a connecting rod 123 structure can be used to form a linkage relationship between the plurality of locking execution pieces 122. The rotating connection structure refers to a pivoting structure for forming a rotating connection with the multi-door equipment, and a rotating shaft 1217 or a hinged support can be used to provide a rotating fulcrum for the locking execution piece 122.

[0036] The plurality of locking execution pieces 122 are connected with the multi-door equipment through the rotating connection structure, the rotating planes of the plurality of locking execution pieces 122 are perpendicular to the planes on which the plurality of door bodies 110 are located, in the locked state, the plurality of locking execution pieces 122 are synchronously rotated to positions for blocking the opening of the door body 110, and in the unlocked state, the plurality of locking execution pieces 122 are synchronously rotated to positions for avoiding the door body 110. The plurality of locking execution pieces 122 keep the same angle under the constraint of the connection mechanism, so as to ensure that all the door bodies 110 enter the locked or unlocked state at the same time.

[0037] In some embodiments, the rotating connection structure includes a plurality of first fixed seats 124 mounted on the oven 100, and the locking execution piece 122 is rotatably connected with the first fixed seat 124. The locking execution piece 122 includes a lock rod 1221 corresponding to the door body 110 and two connecting arms 126, one end of the two connecting arms 126 is connected with the first fixed seat 124, and the other end of the two connecting arms 126 is connected with the two ends of the lock rod 1221 respectively. The connecting arm 126 refers to a rod-shaped or sheet-shaped component connecting the rotating connection part and the lock rod 1221, and the length direction of the connecting arm 126 is perpendicular to the lock rod 1221.

[0038] The plurality of first fixed seats 124 are arranged along the arrangement direction of the door body 110, and at least two first fixed seats 124 are arranged at the bottom of each door body 110. The locking execution piece 122 includes a rotating connection part and a turnover part, the rotating connection part of each locking execution piece 122 is rotatably mounted on the corresponding first fixed seat 124, and the turnover part can be turned relative to the rotating connection part. The rotating plane is perpendicular to the opening plane of the door body 110, and then the turnover part is used to realize the approach or avoidance of the door body 110.

[0039] In the embodiment, the plurality of locking execution members 122 are arranged along the arrangement direction of the plurality of door bodies 110 of the multi-door device, each of the locking execution members 122 corresponds to lock one door body 110, when one of the locking execution members 122 is driven to flip, the plurality of locking execution members 122 are synchronously flipped under the action of the linkage connection mechanism, and are synchronously flipped to be close to the door body 110 to block the opening of the door body 110 in the locked state, and are synchronously flipped to avoid the door body 110 to avoid affecting the opening and closing of the door body 110 in the unlocked state, through such a structure, driving one of the locking execution members 122 to drive the synchronous movement of the remaining plurality of locking execution members 122 is realized.

[0040] Referring to Figure 2 and Figure 5 In some embodiments, the locking execution member 122 includes a lock rod 1221 corresponding to the door body 110 and two connecting arms 126, the lock rod 1221 is located in the flipping part, one end of the two connecting arms 126 is a rotating connection part, and is rotatably connected with the two first fixed seats 124 respectively, the other end of the two connecting arms 126 is connected with the two ends of the lock rod 1221 respectively. The linkage connection mechanism includes a plurality of connecting rods 123, the connecting rod 123 is parallel to the rotating axis of the lock rod 1221, that is, the connecting rod 123 is arranged between the rotating axis of the lock rod 1221 and the lock rod 1221 in the length direction of the connecting arm 126, in the embodiment, the lock rods 1221 of the plurality of locking execution members 122 can be arranged along the same straight line, the plurality of connecting rods 123 can be arranged along the same straight line, and the plurality of lock rods 1221 and the plurality of connecting rods 123 are parallel to the rotating axis of the lock rod 1221. Among them, the connecting rod 123 is arranged corresponding to the interval region of the adjacent door body 110, the plurality of connecting rods 123 sequentially connect the connecting arms 126 of the plurality of locking execution members 122, to transmit the rotating force to the plurality of locking execution members 122, and then when one of the locking execution members 122 is flipped, the remaining locking execution members 122 are synchronously flipped.

[0041] In some embodiments, the lock rod 1221 is a rod-shaped structure, the length direction of the lock rod 1221 is parallel to the arrangement direction of the plurality of door bodies 110, the plurality of lock rods 1221 are arranged at positions corresponding to the plurality of door bodies 110 respectively, the two ends of the lock rod 1221 form a rotatable frame structure with the two first fixed seats 124 through the connecting arms 126, and the plurality of frame structures are sequentially connected by the plurality of connecting rods 123. The connecting rod 123 is arranged in the outer side region of the door body 110, for example, is arranged in the lower region close to the first fixed seat 124 or the door body 110, when the door body 110 is opened, the connecting rod 123 is avoided from interfering with the door body 110.

[0042] In addition, the connecting rod 123 has a set interval in the length direction of the connecting arm 126, and the lock rod 1221 and the connecting rod 123 are parallel to the rotation axis 1217 of the rotating connection part, so that when the lock rod 1221 is flipped to avoid the door body 110, the lock rod 1221 is outside the space region where the door body 110 is located, and when the lock rod 1221 is flipped to be close to the door body 110, the lock rod 1221 is inside the region where the door body 110 is located, and the side of the lock rod 1221 abuts against the outer surface of the door body 110, thereby blocking the door body 110 in the opening direction.

[0043] In some embodiments, the lock rod 1221 or the connecting arm 126 is provided with a buffer block 1261 towards the side of the door body 110, which is used to contact the surface of the door body 110, so as to avoid metal collision and more stably abut against the door body 110. In addition, the lock rod 1221 can also be used as a flipping handle. When the flipping operation is performed, an operator can hold the lock rod 1221 and apply a flipping direction force to the lock rod 1221, so as to realize flipping of one lock rod 1221 and flipping of the remaining lock rods 1221.

[0044] In some embodiments, the length of the lock rod 1221 can be set according to the width of the door body 110, for example, less than or equal to the width of the door body 110, and the length of the connecting rod 123 can be set according to the interval of the adjacent door body 110, for example, less than or equal to the size of the interval. In this embodiment, since the width of the door body 110 of the oven 100 is greater than the interval of the adjacent door body 110, the length of the connecting rod 123 is less than the length of the lock rod 1221.

[0045] The scheme of the present application is that the two ends of the connecting rod 123 are connected with the connecting arms 126 of the adjacent locking actuators 122, and the plurality of connecting rods 123 are sequentially arranged in the interval region between the adjacent door bodies 110 in the arrangement direction of the door bodies 110, so as to sequentially connect the plurality of locking actuators 122 in the arrangement direction of the door bodies 110, and form a segmented linkage structure. When the locking actuators 122 are flipped, the parallel relationship between the lock rod 1221 and the connecting rod 123 makes the locking actions of the plurality of door bodies 110 keep synchronous, and the set interval provides a compensation space for the deformation of the door body 110 or the mounting structure, so as to prevent movement interference caused by local deformation. When linkage is performed, the force is dispersed to each independent connecting arm 126, which significantly reduces the dependence of the structure on the overall rigidity.

[0047] Specifically, the first adjusting structure 1241 can be arranged between the first fixing seat 124 and the multi-door device or between the first fixing seat 124 and the connecting arm 126, for adjusting the position of the locking execution mechanism along the first direction; the second adjusting structure can be arranged between the second fixing seat 125 and the multi-door device or between the second fixing seat 125 and the connecting arm 126, for adjusting the position of the locking execution mechanism along the second direction.

[0048] The first direction can be the X direction of the coordinate system, which is the width direction of the door body 110, the arrangement direction of the plurality of door bodies 110, the transverse direction or the horizontal direction. Figure 1 The second direction can be the Z direction of the coordinate system, which is the length direction of the door body 110, the longitudinal direction or the vertical direction. Figure 1 The second direction can be the Z direction of the coordinate system, which is the length direction of the door body 110, the longitudinal direction or the vertical direction.

In some specific embodiments, the first adjusting structure 1241 includes a waist-shaped hole provided on the first fixing seat 124 and a slidable fastener provided at a corresponding position of the connecting arm 126 or the multi-door device, the length direction of the waist-shaped hole is along the first direction, and the position adjustment of the rotating connection part and the multi-door device or the connecting arm 126 in the first direction is realized by adjusting the fixed position of the fastener in the waist-shaped hole. By adjusting the fixed position of the fastener in the waist-shaped hole, the distance between the two first fixing seats 124 can also be adjusted, and the position of the two sets of locking execution mechanisms in the width direction of the door body 110 or the arrangement direction of the plurality of door bodies 110 can be fine-tuned to avoid the locking execution mechanism from being turned over and blocked due to the deviation of the hole position on the surface of the sheet metal.

[0051] In some specific embodiments, a third adjusting structure is further included, which is configured to adjust the position of the locking actuator in a third direction, which is Figure 1 The Y direction of the coordinate system can be the thickness direction of the door body 110.

[0052] In the embodiment, the plurality of locking actuators 122 are connected to the oven 100 through the first adjusting structure 1241 and / or the second adjusting structure, so that the plurality of locking actuators 122 are independently fine-tuned in the first direction and / or the second direction, and the plurality of locking actuators 122 can adapt to the local deformation of the door body 110 in the arrangement direction of the door body 110.

[0053] For example, when a certain door body 110 or the adjacent wall of the oven appears to be convex, concave, or deformed in the left-right or up-down direction, the position of the locking actuator 122 at the corresponding position of the door body 110 only needs to be adjusted, so that the locking actuator 122 after the adjustment does not interfere with the deformed part during the turnover operation, and the precise cooperation between the locking actuator 122 and the door body 110 is maintained. In this way, the adjusting structure can compensate for the installation position deviation, ensure the synchronization and smoothness of the plurality of locking actuators 122 during the turnover process, and reduce the maintenance frequency and operation failure risk caused by structural deformation.

[0054] Referring to Figure 2 and Figure 4 In some embodiments, the locking assembly 121 includes a lock body 1211 fixed to the multi-door device and an unlocking member 1213 cooperating with the lock body 1211. The unlocking member 1213 and the locking part are arranged in the lock body 1211. The unlocking member 1213 is provided with a lock hole 1212 into which the unlocking member 1213 can be inserted. The locking part is a lock tongue 1214 that can be extended and retracted relative to the lock body 1211. The lock body 1211 is configured such that the unlocking member 1213 can be separated from the lock hole 1212 when the lock tongue 1214 is extended, and the unlocking member 1213 is limited in the lock hole 1212 when the lock tongue 1214 is retracted. The locking cooperation part includes a lock disc 1215 and a rotating shaft 1217 fixed coaxially with the lock disc 1215. The rotating shaft 1217 is connected to the locking actuator. The lock disc 1215 is provided with a lock groove 1216 for clamping cooperation with the lock tongue 1214. The lock tongue 1214 is arranged on the radial side of the lock disc 1215. In the locked state, the lock tongue 1214 is extended and clamped into the lock groove 1216 to limit the rotation of the lock disc 1215. In the unlocked state, the lock tongue 1214 is retracted and abuts against the outer peripheral wall of the lock disc 1215.

[0055] The lock body 1211 is used to carry the installation of the unlocking part 1213 and the lock bolt 1214. The lock bolt 1214 refers to a mechanical blocking component that can be extended and retracted relative to the lock body 1211. Specifically, it can adopt a bolt structure driven by an electromagnet or spring reset. Through the extension and retraction action, it can be clamped or separated with the lock disc 1215. The lock disc 1215 refers to a disc structure provided with a lock slot 1216. The depth and width of the lock slot 1216 are matched with the size of the lock bolt 1214, and are used to limit the rotational freedom of the lock disc 1215 in the locked state. The rotating shaft 1217 refers to a rod-shaped component that transmits rotational motion, and is used to transmit the rotation of the lock disc 1215 to the plurality of locking execution parts 122.

[0056] In this embodiment, the lock bolt 1214 is arranged at the bottom of the lock body 1211, and the extension and retraction direction of the lock bolt 1214 is along the vertical direction. During the locking process, the operator flips the locking execution part 122 upward or toward the door body 110, for example, 180 degrees clockwise or counterclockwise. The lock disc 1215 rotates synchronously. After being flipped into position, the lock slot 1216 is just aligned with the lock bolt 1214 in the vertical direction. At this time, the unlocking part 1213 is rotated, for example, 90 degrees, and the lock bolt 1214 is controlled to extend out through the mechanical structure inside the lock body 1211. After the lock bolt 1214 extends out, it can be clamped into the lock slot 1216 of the lock disc 1215. The two are limited in the circumferential direction of the lock disc 1215, so that the lock disc 1215 cannot rotate around the rotating shaft 1217. At this time, the plurality of door bodies 110 are limited in the locked state by the plurality of locking execution parts 122.

[0057] During the unlocking process, the unlocking part 1213 is inserted into the lock hole 1212 and reversely rotated, for example, 90 degrees counterclockwise. The lock bolt 1214 is controlled to retract through the mechanical structure inside the lock body 1211. After the lock bolt 1214 retracts, it is separated from the lock slot 1216 and abuts against the outer peripheral wall of the lock disc 1215. The two are un-limited in the circumferential direction of the lock disc 1215, so that the lock disc 1215 can freely rotate around the rotating shaft 1217. The operator flips the locking execution part 122 downward or away from the door body 110, for example, 180 degrees counterclockwise, so that the plurality of locking execution parts 122 are rotated to the position away from the door body 110. The plurality of door bodies 110 are unlocked. Since the lock bolt 1214 abuts against the outer peripheral wall of the rotating disc and cannot retract, the mechanical mechanism inside the lock body 1211 limits the unlocking part 1213 from being pulled out of the lock hole 1212.

[0058] In some embodiments, the locking actuator is provided with two groups, the locking assembly 121 is arranged between the two groups of locking actuators; the two ends of the rotating shaft 1217 are connected with the two groups of locking actuators respectively; the rotating connection structure includes two second fixed seats 125 which are spaced apart, and the rotating shaft 1217 is rotatably installed in the two second fixed seats 125; specifically, the second fixed seat 125 is provided with a mounting hole, the rotating shaft 1217 is arranged in the mounting hole, and a bushing is arranged between the rotating shaft 1217 and the mounting hole to avoid metal rotation friction. Among them, the two ends of the rotating shaft 1217 are rotatably arranged in the two first fixed seats 124, the connecting arms 126 at the opposite ends of the two groups of locking actuators are rotatably connected with the rotating shaft 1217, and are located between the two first fixed seats 124, so that the connecting arms 126 at the opposite ends of the two groups of locking actuators can be relatively moved along the rotating shaft 1217, and the position of the door body 110 or the arrangement direction of the plurality of door bodies 110 can be adjusted.

[0059] Among them, the locking assembly 121 is arranged in the middle region of the two groups of locking actuators, and can be installed in the middle position of the bottom of the oven 100 through a fixed support, so as to facilitate the control of the movement state of the plurality of locking actuators 122 on both sides of the oven 100. The rotating shaft 1217 line of the rotating shaft 1217 is aligned with the rotating center line of the first fixed seat 124 and the second fixed seat 125, so as to ensure the synchronous rotation of the plurality of locking actuators 122.

[0060] When the locking tongue 1214 of the locking assembly 121 is clamped into the locking groove 1216 of the locking disc 1215, the rotating shaft 1217 is limited to rotate, at this time, the two groups of locking actuators drive the plurality of locking actuators 122 to flip to the position close to the door body 110 synchronously through the connecting arm 126, so as to realize the linkage locking of the plurality of door bodies 110 of the oven 100.

[0061] When the locking tongue 1214 is retracted, the rotating shaft 1217 can be freely rotated, the locking actuator 122 is flipped to the position avoiding the door body 110, and the door body 110 is unlocked. Since the rotating shaft 1217 is coincided with the axis of the rotating connection part, even if the wall of the oven 100 is deformed, the rotating shaft 1217 can still keep synchronous rotation, so as to avoid the jamming problem caused by the deformation of the surface of the oven 100 or the structural misplacement.

[0062] The present application can realize the synchronous locking and unlocking of the plurality of door bodies 110 of the oven 100, and through the position adjustment and linkage control of the plurality of locking actuators 122, the number of door locks and the maintenance cost are reduced, and the movement interference or jamming problem caused by the structural deformation of the multi-door equipment is avoided.

[0063] The scheme of the present application is that the plurality of locking actuators 122 form a modular structure that can be disassembled and combined. When one of the locking actuators 122 fails, only the locking actuator 122 needs to be repaired or replaced, which does not affect the normal use of other locking actuators 122, thereby improving the flexibility of equipment assembly. In addition, the number of locking actuators 122 can be freely set according to the number of door bodies 110 to adapt to ovens 100 of different lengths or ovens 100 with different numbers of door bodies 110, thereby improving production efficiency during equipment manufacturing.

[0064] Correspondingly, the present application further provides a multi-door equipment. The multi-door equipment includes an oven 100, a plurality of door bodies 110 arranged on the oven 100, and a door lock device 120 for locking or unlocking the plurality of door bodies 110.

[0065] The multi-door equipment of the present application is a coating equipment, and the oven 100 refers to a main body structure carrying the plurality of door bodies 110. The door body 110 is an independent unit that can be opened and closed and is installed on the oven 100. Each door body 110 corresponds to an independent opening area of the oven 100. The door body 110 is rotatably connected to the edge of the opening area of the oven 100 through a hinge 111. The side opposite to the hinge 111 is provided with a switch member 112 having a handle. The door body 110 is locked to the oven 100 through the switch member 112.

[0066] Referring to Figure 1 and Figure 2 In some specific embodiments, the door body 110 is provided with a safety chain 113. One end of the safety chain 113 is fixedly connected to the door body 110, and the other end is detachably connected to the lock rod 1221. When the door body 110 is in a locked state, the safety chain 113 is clamped with the lock rod 1221, so that the lock rod 1221 is locked by the safety chain 113. The double locking of the lock rod 1221 is achieved in cooperation with the door lock assembly, which avoids the lock rod 1221 from being flipped in the unlocking direction in the state that the door lock assembly is opened, thereby further improving the safety.

[0067] The coating equipment can include a plurality of ovens 100, and each oven 100 is provided with a plurality of door bodies 110. The locking actuator of the present application adopts a segmented structure, which can realize synchronous locking and unlocking while allowing each locking actuator 122 to independently adapt to the local deformation of the oven 100, effectively reducing the number of locks and overcoming the motion jam defect caused by the deformation of the oven 100.

[0068] In some embodiments, the multi-door device further comprises a control part, the control part is provided with a placing part for placing the unlocking part 1213 of the locking assembly 121; when the door locking device 120 is in the locked state and the unlocking part 1213 is placed in the placing part, the multi-door device enters the first state capable of running; when the temperature in the oven 100 is in the safe range and the unlocking part 1213 is separated from the placing part, the multi-door device enters the second state incapable of running. The control part refers to an operation platform integrated with the running control function of the device, and the placing part refers to a physical structure for storing the unlocking part 1213, so as to ensure that the unlocking part 1213 is stable when being inserted.

[0069] In this embodiment, the placing part is signal-connected with the control system of the multi-door device. In the first state, the position of the unlocking part 1213 in the placing part is detected through an electrical signal, so as to ensure that the device only runs under the safe condition that the locking state is ensured and the unlocking part 1213 is stored in the placing part. In the second state, the device is prevented from being touched by the operator when the device is in the running state or the internal temperature of the oven 100 has not dropped to the safe range, by cutting off the power supply of the device or turning off the device.

[0070] Specifically, when the door locking device 120 is in the locked state, the latch 1214 is clamped into the lock groove 1216 of the lock disc 1215, the mechanical mechanism in the lock body 1211 releases the unlocking part 1213, the unlocking part 1213 is pulled out of the lock hole 1212 and then stored in the control part by the operator. At this time, the control system of the multi-door device receives the electrical signal of the unlocking part 1213 in place of the control part, controls the multi-door device to enter the first state, and supplies the multi-door device to run normally.

[0071] When the door locking device 120 is in the unlocked state, the latch 1214 cannot be retracted because it abuts against the outer peripheral wall of the rotating disc, the mechanical mechanism in the lock body 1211 limits the unlocking part 1213 from being pulled out of the lock hole 1212, that is, the unlocking part 1213 is in the state of being separated from the control part. At this time, the control system of the multi-door device receives the electrical signal of the unlocking part 1213 not in place of the control part, and detects that the internal temperature of the oven 100 is in the safe range, controls the multi-door device to enter the second state, so as to facilitate the operator to overhaul and maintain.

[0072] The technical scheme provided by the application overcomes the motion interference problem caused by the local deformation of the oven 100 by using a segmented locking execution mechanism. In addition, the signal linkage between the control part and the unlocking part 1213 can realize the association between the device running and the door locking state, which not only reduces the cost, but also improves the safety and maintenance convenience of the device operation.

Many modifications and variations of this application can be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. It is intended that the scope of the application be defined by the scope of the patent and by the claims as allowed by the patent office, which can include adaptations based on the description, equivalents, and / or substitutions of elements individually or collectively to the entire disclosure.
