Description

Technical Field

[0001] The present application relates to the technical field of product production lines, and in particular to a locking mechanism, a rotating device and a suspended conveying equipment. Background Art

[0002] During the production process, products often need to be transported to different workstations for different processing or testing. For example, when the interactive large screen is completed, different projects need to be tested. When the interactive large screen moves on the conveyor track, it will rotate due to the vibration of the movement and the influence of the external environment.

[0003] In the existing technology, manual assistance is often required to hold the interactive screen during transportation. However, this method results in high labor costs and increases personnel safety risks. Not only is it difficult to ensure that the interactive large screen does not rotate during transportation, but the direction and strength of the manual force are uncertain, and it may also affect the suspension components. Summary of the Invention

[0004] Based on the above situation, the main purpose of this application is to provide a locking mechanism, a rotating device and a suspended conveying equipment, which can realize automatic self-locking during the conveying process of the suspended parts and automatic unlocking when in place, which is conducive to automated production and can reduce the impact on the suspended parts.

[0005] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0006] A locking mechanism for a rotating device, the rotating device comprising a mounting seat and a rotating disk rotatably connected to the mounting seat, the outer peripheral side wall of the rotating disk having a plurality of limiting grooves uniformly distributed along its circumference; the locking mechanism comprising a first fixed plate, a first movable plate, a second movable plate, and a second fixed plate stacked in sequence, as well as a first locking member, a second locking member, a guide member, a reset member, and a drive assembly;

[0007] and a control button which is located adjacent to the first and second guide slots and which is located adjacent to the first and second guide slots and which is located adjacent to the first and second guide slots.

[0008] The driving assembly is arranged on one side of the turntable, and is used to drive the two movable plates to drive the locking members to move so that the turntable is converted from a locked state to an unlocked state. In the unlocked state, each of the locking members is separated from the limiting grooves.

[0009] Optionally, in the locked state, the locking piece on one of the two movable plates is in limiting engagement with the limiting groove, and the locking piece on the other movable plate abuts against a protrusion formed by two adjacent limiting grooves.

[0010] Optionally, two first locking members are provided; one second locking member is provided, and the two first locking members are respectively located on both sides of the second locking member along the circumference of the turntable.

[0011] Optionally, the first locking member and the second locking member are located on the same side of the two movable plates along the extension direction of the first guide groove, and the sides of the two movable plates away from the first locking member are arranged to form a pushing plane; the driving assembly includes a push plate, which is slidably arranged relative to the two fixed plates along the extension direction, and its plate surface can push against the two pushing planes.

[0012] Optionally, the guide member includes a guide portion and a limiting portion, both of which are strip-shaped, wherein the guide portion extends along the thickness direction of the first fixing plate and is slidably inserted into the corresponding first guide groove and second guide groove; one end of the limiting portion is connected to the guide portion, and the other end extends in a direction away from the guide portion, and the limiting portion is located in the first guide groove, and its length is less than the length of the first guide groove;

[0013] The reset piece is sleeved on the limiting portion.

[0014] Optionally, the first fixing plate and the second fixing plate are respectively provided with mounting holes, and both ends of the guide portion are respectively plug-fitted into the two mounting holes.

[0015] Optionally, the two movable plates are respectively provided with two first guide grooves and two second guide grooves. On the same movable plate, the two first guide grooves are arranged side by side and located on the same side along the extension direction of the first guide groove, and the two second guide grooves are located side by side on the other side.

[0016] Optionally, each of the movable plates has two side surfaces that are oppositely arranged and parallel to the extending direction of the first guide groove.

[0017] The locking mechanism further includes a limiting member connected to at least one of the fixing plates, and the limiting member is disposed outside the two side surfaces;

[0018] The locking mechanism further includes a support member, which is arranged between the first fixed plate and the second fixed plate and is located outside the two movable plates.

[0019] The present application also relates to a rotating device, comprising a turntable and the aforementioned locking mechanism, wherein the outer peripheral side wall of the turntable is provided with a plurality of limiting grooves along its circumference.

[0021] When the mounting base slides to a preset position, the driving assembly drives the two movable plates to move so that the turntable is in an unlocked state.

[0022] The locking mechanism of the present application is provided with a plurality of stacked plates. By arranging the reset member in the first guide groove of the different movable plates in the middle, each movable plate in the middle can slide independently under the reset force of the reset member, so that the first locking member and the second locking member connected to each movable plate can respectively cooperate with different position limits on the turntable, so that in the locked state, at least one locking member can cooperate with the limiting groove to limit the turntable circumferentially; at the same time, by adding a driving component, the movable plate can be pushed to slide by the driving force when unlocking is required, so that the first locking member and the second locking member are disengaged from each limiting groove, so that the turntable is in a rotatable state.

[0023] When the locking mechanism is applied to a suspended conveying device, the drive assembly is positioned at a preset position on the conveying track, and the mounting base is slidably mounted on the conveying track. Thus, during the entire sliding process, the fixed plate and the movable plate slide along with the mounting base and the turntable, while the reset members simultaneously engage at least one of the first locking member and the second locking member with the limiting groove. At the preset position on the track, the locking mechanism can be unlocked by the drive assembly. Clearly, the locking mechanism of the present application not only saves manpower and is better adapted to automated production lines, but also effectively prevents the rotation of the suspension member during transportation, reducing the impact on the suspension member.

[0024] Other beneficial effects of the present application will be explained through the introduction of specific technical features and technical solutions in the specific implementation methods. Through the introduction of these technical features and technical solutions, those skilled in the art should be able to understand the beneficial technical effects brought about by the technical features and technical solutions.

[0048] The present application is described below based on examples, but the present application is not limited to these examples. In the detailed description of the present application below, some specific details are described in detail. In order to avoid obscuring the essence of the present application, well-known methods, processes, procedures, and components are not described in detail.

[0051] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0052] See also Figure 1-12 The present application provides a locking mechanism for a rotating device, which can be used in production line equipment for various products, such as interactive large-screen production line equipment. The production line equipment can be an assembly line production line equipment, such as the suspended conveying equipment described below, or a production line equipment for a specific workstation. The rotating device includes a mounting seat 1 and a turntable 3 rotatably connected to the mounting seat 1, and the outer peripheral side wall of the turntable 3 is uniformly distributed with a plurality of limiting grooves 31 along its circumference; the locking mechanism includes a locking assembly 2 and a driving assembly 6, wherein the locking assembly 2 includes a first fixed plate 22, a first movable plate 24, a second movable plate 25, and a second fixed plate 23, which are stacked in sequence, as well as a first locking member 211, a second locking member 212, a guide member 26, and a reset member 27.

[0053] The first fixed plate 22 and the second fixed plate 23 are fixedly connected and installed on the mounting seat 1, and the guide member 26 is installed on at least one fixed plate; the first movable plate 24 and the second movable plate 25 are both provided with a first guide groove 242 and a second guide groove 243 extending in the same direction, the length of the first guide groove 242 is greater than the length of the second guide groove 242, and the first guide groove 242 of one of the first movable plate 24 and the second movable plate 25 corresponds to the second guide groove 243 of the other, and the corresponding set of guide grooves is slidably matched with the same guide member 26, and a reset member 27 is provided between the first guide groove 242 and the guide member 26; the first movable plate 24 is connected to a first locking member 211, and the second movable plate 25 is connected to a second locking member 212, and the positions of the locking members 21 are staggered in the circumferential direction, and under the reset force of the reset member 27, at least one locking member 21 is limitedly matched with the limiting groove 31 to put the turntable 3 in a locked state ( Figure 1 Show).

[0054] The driving assembly 6 is provided on one side of the turntable 3 and is used to drive the two movable plates to drive the locking member 21 to move so that the turntable 3 is converted from the locked state to the unlocked state. Figure 3 、 Figure 4 As shown in FIG, each locking member 21 is separated from the limiting groove 31.

[0055] See also Figure 1 In the present application, the locking mechanism is applied to the rotating device, and the rotating device is applied to the suspended conveying equipment. Specifically, the suspended conveying equipment includes a conveying track 5. The aforementioned mounting seat 1 can move along the conveying track 5. The lower side of the mounting seat 1 can mount a suspension part, thereby driving the suspension part to move along the conveying track 5. In the circumferential direction of the turntable 3, the position of the suspension part is constant relative to the turntable 3, that is, the turntable 3 rotates and stops synchronously with the suspension part. Therefore, when the turntable 3 is in a locked state, the suspension part cannot rotate. Only when the turntable 3 is in an unlocked state can the suspension part rotate. Therefore, when the mounting seat 1 moves along the conveying track 5, the turntable 3 is in a locked state, so that the suspension part cannot rotate. Therefore, there is no need to manually grasp the suspension part during transportation, which also reduces the impact on the suspension part.

[0056] For ease of understanding, in one embodiment, the mounting base 1 is located at the uppermost side, the turntable 3 is rotatably mounted on the lower side of the mounting base 1, and the locking assembly 2 is located between the mounting base 1 and the turntable 3. Figure 5 and Figure 6The locking assembly 2 includes a first fixed plate 22, a first movable plate 24, a second movable plate 25 and a second fixed plate 23 stacked up and down, wherein the first fixed plate 22 and the second fixed plate 23 are fixedly connected to each other and are relatively fixed on the mounting base 1, and the first movable plate 24 and the second movable plate 25 can slide relative to the two fixed plates in a sliding direction, and the sliding direction is horizontal and linear.

[0057] The first movable plate 24 is connected to a first locking member 211, and the second movable plate 25 is connected to a second locking member 212. The first locking member 211 and the second locking member 212 extend in the vertical direction. Since the first movable plate 24 and the second movable plate 25 can slide in the sliding direction, the first locking member 211 and the second locking member 212 can also slide in the sliding direction, so that the first locking member 211 is close to or away from the turntable 3. The outer periphery of the turntable 3 is evenly distributed with a plurality of limiting grooves 31. The shapes of the first locking member 211 and the second locking member 212 are consistent with the limiting grooves 31. 1, so that when the two locking members 21 are close to the turntable 3, the locking members 21 can be inserted into the limiting groove 31 (first position), and the two movable plates cannot rotate in the circumferential direction, so that the first locking member 211 and the second locking member 212 cannot rotate in the circumferential direction, thereby preventing the turntable 3 from rotating, and putting the turntable 3 in a locked state. When the first locking member 211 and the second locking member 212 are away from the turntable 3, the first locking member 211 and the second locking member 212 are both disengaged from the limiting groove 31 (second position), so that the turntable 3 can rotate, putting the turntable 3 in an unlocked state. The state of the turntable 3 can be controlled by sliding the first movable plate 24 and the second movable plate 25 in the sliding direction as described above.

[0058] Specifically, the first movable plate 24 and the second movable plate 25 are both provided with a first guide groove 242 and a second guide groove 243 extending in the sliding direction, and in the up and down directions, the first guide groove 242 on one movable plate corresponds to the second guide groove 243 on the other movable plate, and the guide member 26 is connected to the fixed plate so that the position of the guide member 26 and the fixed plate is fixed, and the guide member 26 passes through the opposite first guide groove 242 and the second guide groove 243, and then a reset member 27 is set in the first guide groove 242, and the reset member 27 can be a member with deformation ability. And an elastic component that can apply force to the outside, such as a spring or a shrapnel, one end of the reset member 27 is against the guide member 26, and the other end is against the first guide groove 242. The reset member 27 will be telescopically deformed, and the reset member 27 will continuously apply a first thrust (reset force) to the movable plate. The direction of the first thrust is the same as the direction from the second position to the first position, thereby pushing the movable plate to move toward the first position, so that the locking member 21 can cooperate with the limiting groove 31 and prevent the locking member 21 from moving to the second position non-artificially in the first position.

[0059] See also Figure 7 Taking the reset member 27 as a spring as an example, the first guide groove 242 has a first end 2421 and a second end 2422 relative to each other. The direction from the first end 2421 to the second end 2422 is consistent with the direction from the first position to the second position. The guide member 26 extends into the first guide groove 242 and is spaced apart from the first position. Preferably, the guide member 26 extends into the second end 2422. The spring is arranged in the first guide groove 242, and one end of the spring abuts against the first end 2421, and the other end of the spring abuts against the guide member 26, so that the spring can apply a first thrust from the second end 2422 to the first end 2421 through the guide member 26, thereby causing the movable plate to be in the first position.

[0060] The first movable plate 24 and the second movable plate 25 are both provided with a first guide groove 242 , and each first guide groove 242 is provided with a reset member 27 , that is, both movable plates are subjected to the first thrust, so that the first locking member 211 and the second locking member 212 can be pressed toward the turntable 3 to lock the turntable 3 .

[0061] The second guide groove 243 is provided to facilitate the passage of the guide member 26 so that the guide member 26 can reach the first guide groove 242; in addition, the second guide groove 243 also has a certain length in the sliding direction to meet the sliding of the corresponding sliding plate in the sliding direction.

[0062] The first locking member 211 and the second locking member 212 are both connected to the same side of the sliding direction of the corresponding movable plate (turntable 3); the driving component 6 is arranged on the other side of the sliding direction of the turntable 3, and the driving component 6 and the locking member 21 are located on both sides of the movable plate in the sliding direction, that is, the direction between the driving component 6 and the movable plate is the direction from the first position to the second position, so that the driving component 6 can apply a second thrust to the movable plate (opposite to the direction of the first thrust) to the movable plate, so that the movable plate moves to the second position to unlock the turntable 3.

[0063] Therefore, when the suspension part needs to be rotated, the first movable plate 24 and the second movable plate 25 can be pushed to the second position through the driving component 6, so that the turntable 3 is in an unlocked state. At this time, the turntable 3 can be rotated according to the required rotation angle, so that the suspension part rotates the required angle, and then the driving component 6 is withdrawn. The first movable plate 24 and the second movable plate 25 will slide to the first position under the action of the first thrust of the reset member 27, so that the turntable 3 is in a locked state again, so that the angle of the suspension part after rotation remains unchanged.

[0064] Specifically on the suspended conveying equipment, the driving component 6 is installed at a preset position of the conveying track 5. After the mounting seat 1 moves to the preset position, the turntable 3 can be unlocked by the driving component 6. Then, the turntable 3 can be rotated to the required angle, so that the mounting seat 1 maintains the same angle after rotation during the subsequent movement.

[0065] In one embodiment, the turntable 3 is rotatably connected to the mounting base 1 via a rotating shaft 4. The turntable 3 is connected to the rotating shaft 4 (e.g., by welding or keying) so that the rotating shaft 4 and the turntable 3 can rotate synchronously. The upper portion of the rotating shaft 4 is rotatably connected to the mounting base 1, and the lower portion of the rotating shaft 4 can be connected to a suspension member. The turntable 3 is located in the middle area of the rotating shaft 4.

[0066] A first through hole 221 is provided on the first fixed plate 22 and the second fixed plate 23. The first through hole 221 is a circular hole for the rotating shaft 4 to pass through. A second through hole 241 is provided on the first movable plate 24 and the second movable plate 25. The second through hole 241 (waist-shaped hole) extends in the sliding direction and is larger than the sliding stroke of the two movable plates. The second through hole 241 is also for the rotating shaft 4 to pass through, and prevents the two movable plates from interfering with the rotating shaft 4 when sliding.

[0067] The first locking member 211 and the second locking member 212 are both cylindrical structures, and the tooth groove of the limiting groove 31 is an arc groove. The radius of the arc groove matches the radius of the locking member 21, or in other words, the radius of the arc groove is slightly larger than the radius of the locking member 21, so that in the first position, the cylindrical surface of the locking member 21 can fit with the arc groove, so that the locking member 21 can press the limiting groove 31, thereby improving the limiting effect of the locking member 21 on the turntable 3.

[0068] The limiting groove 31 also includes two guide surfaces connected to the arc groove. In the circumferential direction of the turntable 3, the two guide surfaces are arranged opposite to each other. In the radial direction of the turntable 3, from the outside to the inside, the distance between the two guide surfaces gradually decreases, so that the opening of the limiting groove 31 (from the outside to the inside) gradually becomes smaller, making it convenient for the locking piece 21 to cooperate with the limiting groove 31 through the opening of the limiting groove 31.

[0069] Of course, the guide surface is preferably a curved surface, but can also be a flat surface.

[0070] Since the first movable plate 24 and the second movable plate 25 can both slide independently relative to the fixed plate, the first locking member 211 and the second locking member 212 can also slide independently relative to the fixed plate, and a protrusion is formed between adjacent limiting grooves 31 of the turntable 3. The angle of the turntable 3 during rotation is uncertain. In some cases, when the first locking member 211 and the second locking member 212 move toward the first position, the locking member 21 may just abut against the protrusion, making it impossible for the locking member 21 to cooperate with the limiting groove 31, thereby affecting the locking of the turntable 3.

[0071] In the present application, the first locking member 211 and the second locking member 212 are offset in the circumferential direction of the turntable 3, and the circular angle between them relative to the axis of the turntable 3 is an integer multiple of the non-tooth pitch angle. This means that if the first locking member 211 is exactly against the protrusion of the turntable 3, the second locking member 212 will not be against the protrusion, but will smoothly cooperate with the limiting groove 31, so that no matter what, at least one limiting column will be able to cooperate with the limiting groove 31 to keep the turntable 3 in a locked state.

[0072] In the locked state, the locking piece 21 of one of the two movable plates is in limited engagement with the limiting groove 31 , and the locking piece 21 of the other movable plate abuts against a protrusion formed by two adjacent limiting grooves 31 .

[0073] The central angle between the second locking member 212 and the first locking member 211 is N+0.5 times the pitch angle (e.g. Figure 9 1.5 times as shown), wherein N is a natural number, so that when the two movable plates move from the second position to the first position, even if some locking members 21 just hit the protrusions of the turntable 3, another part of the locking members 21 can just correspond to the limiting grooves 31, thereby ensuring that in any case in the first position, at least one locking member 21 can be inserted into the limiting groove 31.

[0074] In this configuration, only one locking member 21 between the first locking member 211 and the second locking member 212 can cooperate with the limiting groove 31 , while the other locking member 21 can only abut against the protrusion.

[0075] Of course, the central angle between the first locking member 211 and the second locking member 212 can be an integer multiple of the pitch angle, so that in the first position, the first locking member 211 and the second locking member 212 will simultaneously match their respective corresponding matching grooves.

[0076] Two first locking members 211 are provided; one second locking member 212 is provided, and the two first locking members 211 are respectively located on both sides of the second locking member 212 along the circumference of the turntable 3 .

[0077] In the first position, the direction between the second locking member 212 and the center of the turntable 3 is consistent with the sliding direction. That is, when the second locking member 212 is used to lock the turntable 3, the second locking member 212 cooperates with the limiting groove 31 and presses the turntable 3 toward the center of the turntable 3. Therefore, the first thrust of the second locking member 212 does not cause the turntable 3 to rotate, and the purpose of locking the turntable 3 is achieved. When the two first locking members 211 respectively cooperate with the limiting grooves 31, the two first locking members 211 are respectively located on either side of the sliding direction passing through the center of the turntable 3. The resultant force formed by the first thrust of the first locking members 211 also points to the center of the turntable 3, and thus does not cause the turntable 3 to rotate, thereby ensuring that the turntable 3 cannot rotate in the first position.

[0078] Specifically, the center angle of the two first locking members 211 is an integer multiple of the pitch angle (for example Figure 9 3 times as shown), so that the two second locking members 212 on the first movable plate 24 can be inserted into the corresponding limiting grooves 31 at the same time, and the central angle between the second locking member 212 and any one of the first locking members 211 is N+0.5 times the pitch angle (for example Figure 10 1.5 times as shown), where N is a natural number, so that when the two movable plates move from the second position to the first position, even if some locking members 21 just abut against the protrusions of the turntable 3, another part of the locking members 21 can be smoothly inserted into the limiting groove 31, thereby ensuring that in any case in the first position, at least one locking member 21 can be inserted into the limiting groove 31.

[0079] like Figure 9 In the embodiment shown, the two first locking members 211 are inserted into the matching grooves, and the second locking member 212 abuts against the protrusion of the rotating disk 331; Figure 10 In the illustrated embodiment, the second locking member 212 is inserted into the matching groove, and the two first locking members 211 abut against the protrusions of the turntable 3 .

[0080] Of course, in another embodiment, the number of the first locking member 211 may be one, and the number of the second locking member 212 may be two.

[0081] The first locking member 211 and the second locking member 212 are located on the same side of the two movable plates along the extension direction (sliding direction) of the first guide groove 242, and the two movable plates are arranged to form a pushing plane on the side away from the first locking member 211; the driving assembly 6 includes a push plate 61, which is slidably arranged relative to the two fixed plates along the extension direction (sliding direction), and its plate surface can push against the two pushing planes.

[0082] The movable plate protrudes beyond the fixed plate at the end facing the drive assembly 6, causing the push plate 61 to abut against the protruding end of the movable plate. The protruding end is then pushed and slid into the fixed plate until the push plate 61 abuts the fixed plate, at which point the locking member 21 reaches the second position. The push plate 61 can only move to a position where it abuts against the fixed plate, limiting its travel. This prevents excessive travel between the first and second positions and protects the movable plate from being subjected to an excessive second thrust.

[0083] As for the driving assembly 6, the driving assembly 6 includes a pushing member, which includes a push plate 61 and a connecting plate 62 connected to each other. The connecting plate 62 is slidably connected to a preset position along the sliding direction, and the push plate 61 is opposite to the two movable plates.

[0084] The connecting plate 62 is arranged horizontally, and the push plate 61 is connected to one end of the connecting plate 62. When the mounting base 1 moves to the preset position, the push plate 61 faces the movable plate. Therefore, when the connecting plate 62 moves toward the movable plate in the sliding direction, the push plate 61 moves toward the movable plate and pushes the two movable plates to slide to the second position to unlock the turntable 3.

[0085] See also Figure 1 The power device of the connecting plate 62 can be a cylinder 63, which pushes the connecting plate 62 to slide in the sliding direction. Of course, the power device of the connecting plate 62 can also be a linear motor, etc.

[0086] See also Figure 6 、 Figure 7 and Figure 11 The guide member 26 includes a strip-shaped guide portion 261 and a limiting portion 262. The guide portion 261 extends along the thickness direction of the first fixing plate 22 and is slidably inserted into the corresponding first guide slot 242 and second guide slot 243. One end of the limiting portion 262 is connected to the guide portion 261, and the other end extends away from the guide portion 261. The limiting portion 262 is located in the first guide slot 242 and is shorter than the length of the first guide slot 242. The reset member 27 is sleeved on the limiting portion 262.

[0087] The guide member 26 is T-shaped as a whole, and the guide portion 261 is vertically arranged and connected to the fixed plate. The two ends of the guide portion 261 are respectively connected to the two fixed plates (for example, for insertion into the mounting holes 222 on the fixed plate as described below); the middle part of the guide portion 261 is located in the first guide groove 242, and the length of the limiting portion 262 is less than the length of the first guide groove 242. The limiting portion 262 is horizontally arranged and arranged in the first guide groove 242 parallel to the sliding direction. The interval between the limiting portion 262 and the first end 2421 is greater than or equal to the stroke of the movable plate, so that when the movable plate slides to the second position, at most the limiting portion 262 and the first end 2421 are abutted against each other, and the spring (reset member 27) is sleeved on the limiting portion 262, limiting the compression direction of the spring, so that the spring can stably apply the first thrust to the movable plate.

[0088] Of course, the guide member 26 may also only include the guide portion 261 .

[0089] The length of the second guide groove 243 is smaller than that of the first guide groove 242 . The first fixing plate 22 and the second fixing plate 23 are respectively provided with mounting holes 222 , and both ends of the guide portion 261 are respectively inserted into the two mounting holes 222 .

[0090] The first guide groove 242 and the second guide groove 243 can be completely distinguished according to their length. Therefore, during assembly, it is only necessary to set the reset member 27 in the first guide groove 242 with a longer length to avoid incorrect setting of the reset member 27 and the limiting portion 262. In addition, the length of the limiting portion 262 is preferably longer than the length of the second guide groove 243, so that the limiting portion 262 can only be located in the first guide groove 242 and cannot be set in the second guide groove 243; and there is no reset member 27 in the second guide groove 243 to avoid mutual interference between the reset members 27 in the first guide groove 242 and the second guide groove 243 that are opposite to each other, thereby ensuring the reset ability of the reset member 27, so that the first movable plate and the second movable plate 25 can switch between two positions.

[0091] Of course, the length of the first guide groove 242 may also be the same as the length of the second guide groove 243 , that is, the reset member 27 may also be provided in the second guide groove 243 .

[0092] The two movable plates are respectively provided with two first guide grooves 242 and two second guide grooves 243. On the same movable plate, the two first guide grooves 242 are arranged side by side and located on the same side along the extension direction of the first guide groove 242, and the two second guide grooves 243 are located side by side on the other side.

[0093] Each movable plate is subjected to the first thrust provided by the two reset members 27, and in the sliding direction, the force application points of the two reset members 27 on the movable plate are located at the same position, ensuring that the movable plate slides along the sliding direction and preventing the movable plate from deflecting.

[0094] In addition, the cross-section of the guide portion 261 is preferably rectangular, and when the guide portion 261 is slidably inserted into the first guide groove 242 and the second guide groove 243, the wall surfaces of the first guide groove 242 and the second guide groove 243 fit into the side surfaces of the guide portion 261, so that the guide portion 261 cannot rotate relative to the guide groove, so that the movable plate can only slide along the sliding direction due to the cooperation between the guide groove and the guide portion 261.

[0095] See also Figure 8 Each movable plate has two side surfaces that are oppositely arranged and parallel to the extension direction (sliding direction) of the first guide groove 242. The locking assembly 2 also includes a limiting member 28 connected to at least one fixed plate, and the limiting member 28 is fitted outside the two side surfaces.

[0096] The movable plate includes a first side surface and a second side surface that are opposite to each other. The first side surface and the second side surface are parallel to the sliding direction. The first side surface corresponds to at least two limit members 28, and these limit members 28 are arranged along the sliding direction. The second side surface corresponds to at least two limit members 28, and these limit members 28 are arranged along the sliding direction. The first side surface slides with the limit member 28, and the second side surface slides with the limit member 28. The position of the limit member 28 relative to the fixed plate remains unchanged, thereby limiting the two movable plates to slide only along the sliding direction, preventing the first movable plate 24 and the second movable plate 25 from rotating.

[0097] See also Figure 8 The locking assembly 2 further includes a support member 29 , which is disposed between the first fixed plate 22 and the second fixed plate 23 and is located outside the two movable plates.

[0098] The first fixed plate 22 is separated from the second fixed plate by a support member 29, so that the first movable plate 24 and the second movable plate 25 will not be compressed by the two fixed plates, so that the first movable plate 24 and the second movable plate 25 can slide in the sliding direction; that is, in the thickness direction of the fixed plate, the height of the support member 29 is greater than the sum of the thicknesses of the first movable plate 24 and the second movable plate 25, so that the two movable plates will not be compressed by the two fixed plates.

[0099] The support member 29 may be Figure 8 In the embodiment shown, there are four such devices, which are located at the four corners of the fixing plate.

[0100] A first notch 223 is provided on the first fixed plate 22, and a second notch 231 is provided on the second fixed plate 23. The two fixed plates are fixedly connected by a locking member 21 passing through the first notch 223 and the second notch 231; the movable plate is provided between the two fixed plates, and one end of the locking member 21 provided on the movable plate extends out of the fixed plate.

[0101] The two fixed plates are spaced apart in the upper and lower parts and fixed to each other by a locking piece 21. The first fixed plate 22 is connected to the mounting seat 1. The movable plate is confined between the two fixed plates so that the movable plate can slide along the sliding direction. One end of the locking piece 21 of the movable plate extends out of the fixed plate so that the locking piece 21 is located on the outside of the fixed plate, thereby allowing the locking piece 21 to slide in the sliding direction.

[0102] The present application also provides a rotating device, including a mounting seat 1, a turntable 3 and the aforementioned locking mechanism. The turntable 3 is rotatably connected to the mounting seat 1, and the outer side wall of the turntable 3 is provided with multiple limiting grooves 31 along its circumference; the driving component 6 is fixedly arranged.

[0103] In the rotating device, the position of the locking mechanism and the position of the driving assembly 6 can be constant or variable. That is, in one embodiment, the mounting base 1 can be in a fixed position, and the driving assembly 6 and the locking mechanism correspond to each other. In another embodiment, the mounting base 1 can also be installed on the conveying track 5, so that the position of the mounting base 1 is variable. When the mounting base 1 moves to the preset position, the driving assembly 6 can make the turntable 3 unlocked.

[0104] See also Figure 12 The present application also provides a suspended conveying equipment, including a conveying track 5 and the aforementioned rotating device, the mounting seat 1 is slidably installed on the conveying track 5; the driving component 6 is installed at a preset position of the conveying track 5; during the sliding process of the mounting seat 1, when the mounting seat 1 slides to the preset position, the driving component 6 drives the two movable plates to move so that the turntable 3 is in an unlocked state.

[0105] Among them, the mounting base 1, the turntable 3, the locking mechanism and the conveying track 5 have all been described above and will not be repeated here.

[0106] In this application, the drive assembly 6 is positioned at a preset position on the conveyor track 5, and the mounting base 1 is slidably mounted on the conveyor track 5. Thus, during the entire sliding process, the fixed plates and movable plates slide along with the mounting base 1 and the turntable 3. Simultaneously, under the action of the reset members 27, at least one of the first locking member 211 and the second locking member 212 engages with the limiting groove 31. At the preset position on the track, the lock can be unlocked by the drive assembly 6. Clearly, the locking mechanism of this application not only saves manpower and is better adapted to automated production lines, but also effectively prevents the rotation of the suspension member during transportation, reducing the impact on the suspension member.

[0108] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present application, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present application.
