[0067] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0068] The swing locking structure 100 provided by the present invention is used to lock a swing body, which includes a fixed seat 1, an operating member 2, a locking member 3 and a swing rod 4. The swing rod 4 is pivotally connected to the fixed seat 1, and the swing rod 4 is connected to the swing body and can swing relative to the fixed seat 1 as the swing body swings. Locking the swing of the swing rod 4 means locking the swing of the swing body. The locking member 3 is movably arranged between the fixed seat 1 and the operating member 2. The locking member 3 locks or releases the swing of the swing rod 4 under the drive of the operating member 2. Preferably, the locking member 3 is slidably arranged on the fixed seat 1, and the locking member 3 is slidably arranged on the operating member 2. Preferably, The locking member 3 is slidably inserted into the operating member 2, but is not limited to this. The operating member 2 is slidably arranged on the fixed seat 1, so that the locking member 3 is driven to slide in the left and right direction of the fixed seat 1 (that is, in the direction close to or away from the swing rod 4) by the sliding of the operating member 2 in the up and down direction of the fixed seat 1, thereby locking or releasing the swing of the swing rod 4. In other embodiments, a sliding groove can also be provided on the operating member 2, and the locking member 2 is slidably arranged on the operating member 2 through the sliding groove. The operating member 2 can also be moved relative to the fixed seat 1 in other ways to realize the driving of the locking member 3, so it is not limited to this. When locking, the operating member 2 slides downward and links the locking member 3 to slide in a direction close to the rocking rod 4, thereby locking the rocking rod 4 in a horizontal state to indirectly lock the rocking of the rocking body; when releasing, the operating member 2 slides upward and links the locking member 3 to slide in a direction away from the rocking rod 4, thereby releasing the rocking rod 4 in a locked state to allow the rocking bed to rock freely. Therefore, it is only necessary to control the up and down sliding of the operating member 2 to link the locking member 3 to lock or release the rocking of the rocking rod 4, thereby indirectly releasing or locking the rocking of the rocking body. The structure is simple, low-cost and easy to operate. The rocking locking structure 100 provided by the present invention is suitable for rocking devices such as cradles, rocking chairs and rocking beds, but is not limited thereto. In order to more clearly illustrate the specific structure of the rocking locking structure 100, the following will be used to describe the structure of the rocking locking structure 100. Figures 1 to 32 The rocking bed shown in the first embodiment is described in detail as an example: the rocking bed of the first embodiment includes a support frame 200a, a rocking bed body 200b, a suspension rod 200c and the above-mentioned rocking locking structure 100, please refer to Figures 1 to 10 In the rocking bed, the rocking body is a rocking bed body 200b, the fixed seat 1 is fixed to the support frame 200a, the rocking bed body 200b is connected to the rocking rod 4, the suspension rod 200c is arranged between the rocking rod 4 and the rocking bed body 200b, one end of the suspension rod 200c is pivoted to the rocking bed body 200b, and the other end of the suspension rod 200c is pivoted to the fixed seat 1 through the connecting seat 200d and fixed to the rocking rod 4, the suspension rod 200c and the rocking rod 4 are perpendicular to each other, when the rocking bed body 200b is in use, the rocking bed body 200b swings horizontally, driving the suspension rod 200c and the rocking rod 4 to swing relative to the fixed seat 1 at the same time, so the locking member 3 locks the rocking rod 4 under the drive of the operating member 2, and the rocking of the rocking bed body 200b can be locked.

[0069] See also Figure 1 , Figure 3 as well as Figure 9-10 The swing locking structure 100 also includes a first elastic member 5 and a holding mechanism 6a. The fixed seat 1 is composed of two mounting plates. The mounting plates on the front and rear sides are arranged opposite to each other. The operating member 2, the locking member 3, the rocking rod 4, the first elastic member 5 and the holding mechanism 6a are all located between the two mounting plates. The operating member 2 has a locking position and a releasing position. When the operating member 2 is in the locking position, the locking member 3 locks the rocking rod 4, thereby locking the rocking bed; when the operating member 2 is in the releasing position, the locking member 3 releases the rocking rod 4, thereby allowing the rocking bed to swing arbitrarily; the first elastic member 5 provides an elastic force that causes the operating member 2 to slide from the locking position to the releasing position, and the holding mechanism 6a is used to lock the operating member 2 in the locking position. When locked, the operating member 2 in the releasing position overcomes the elastic force of the first elastic member 5 and slides downward to the locking position (the operating member 2 in the releasing position is shown in FIG. 2 ). Figure 3 , the operating member 2 in the locked position see Fig. 9 ), the holding mechanism 6a locks the operating member 2 in the locking position, so that the locking member 3 slides toward the swing rod 4 to lock the swing rod 4; when releasing the lock, the holding mechanism 6a releases the operating member 2, and the operating member 2 slides upward under the elastic recovery of the first elastic member 5 to reset to the unlocking position, so that the locking member 3 slides away from the swing rod 4 to release the swing rod 4. Preferably, the first elastic member 5 is elastically pressed and arranged between the fixing seat 1 and the operating member 2, so that the arrangement between the components is more compact. More specifically, as follows:

[0070] See also Figure 1 , Figure 3 as well as Figure 9-10One end of the swing rod 4 is pivotally connected to the fixed seat 1, and the other end of the swing rod 4 is provided with a clamping part 41 corresponding to the locking member 3. The locking member 3 is clamped or unclamped with the clamping part 41 under the drive of the operating member 2. The locking member 3 is close to the clamping part 41 and clamped with the clamping part 41 under the drive of the operating member 2 to lock the swing of the swing rod 4. The locking member 3 is away from the clamping part 41 and unclamped with the clamping part 41 under the drive of the operating member 2 to release the swing of the swing rod 4. For example, the locking member 3 is a latch, and the clamping part 41 is a notch. The latch is engaged or unclamped with the notch to achieve locking or releasing of the swing rod 4. The structure is simple, and of course the manufacturer can also modify it according to actual conditions. It needs to be adjusted to other engaging structures; the operating member 2 is provided with an elongated hole 21 and a connecting hole 22, the locking member 3 is inserted into the elongated hole 21 and slidably contacts the elongated hole 21, the sliding of the operating member 2 in the vertical direction of the fixing seat 1 causes the elongated hole 21 to be displaced, and the movement of the elongated hole 21 drives the locking member 3 inserted in the elongated hole 21 to slide, the elongated hole 21 is arranged obliquely, and the elongated hole 21 is inclined along the vertical direction of the fixing seat 1, and the locking member 3 slides along the left and right direction of the fixing seat 1 under the drive of the elongated hole 21 to approach or move away from the swing rod 4; the fixing seat 1 is provided with a first sliding groove 11 (please refer to the second embodiment for details) Figure 15 to Figure 16 ), the locking member 3 is slidably inserted into the first sliding groove 11, and the first sliding groove 11 is arranged along the left and right direction of the fixing base 1. The locking member 3 slides along the left and right direction of the fixing base 1 under the guidance of the first sliding groove 11, with high precision; please refer to Figure 3 as well as Fig. 9 The fixing seat 1 is provided with a second sliding groove 12, and the operating member 2 is slidably arranged in the second sliding groove 12. Preferably, the second sliding groove 12 is arranged along the up-down direction of the fixing seat 1. Of course, in other embodiments, the second sliding groove 12 can also be arranged along other directions as required, so it is not limited thereto. The operating member 2 slides along the up-down direction of the fixing seat 1 under the guidance of the second sliding groove 12, and has high precision. The swing rod 4 extends into the operating member 2 through the connecting hole 22 and locks or releases the locking member 3 in the elongated hole 21. The connecting hole 22 is connected to the elongated hole 21 and is opened on the left or right side of the operating member 2, or is opened on both the left and right sides of the operating member 2 at the same time. Since the rocking bed is connected by two suspension rods 200c to achieve stable swinging of the rocking bed body 200b, correspondingly, the rocker arm 4, the locking piece 3, the elongated hole 21 cooperating with the locking piece 3, the first sliding groove 11 and the connecting hole 22 are all set in two, and the suspension rod 200c, the rocker arm 4, the locking piece 3, the elongated hole 21, the first sliding groove 11 and the connecting hole 22 are arranged symmetrically. Preferably, the two elongated holes 21 together form an inverted "eight" shape, but are not limited to this.

[0071] See also Figure 1 , Figure 3 as well as Figure 9-10In this embodiment, the retaining mechanism 6a includes a locking member 61, a release button 62 and a second elastic member 63. The locking member 61 is slidably inserted in the fixing seat 1. The locking member 61 has a positioning portion 611. The operating member 2 is provided with a retaining portion 23 corresponding to the positioning portion 611. The positioning portion 611 cooperates with the retaining portion 23 to lock the operating member 2 in the locking position. The structure is simple and can ensure the position accuracy of the operating member 2. Preferably, one of the positioning portion 611 and the retaining portion 23 is a protrusion, and the other of the positioning portion 611 and the retaining portion 23 is a locking groove or a locking hole. In this embodiment, the positioning portion 611 is a protrusion and the retaining portion 23 is a locking hole, but it is not limited to this. Specifically, the second elastic member 63 provides an elastic force that causes the positioning portion 611 to extend into the retaining portion 23. The release button 62 is installed on the engaging member 61 and is located outside the fixing seat 1. The release button 62 presses the engaging member 61 to separate the positioning portion 611 from the retaining portion 23 to release the lock. When locked, the retaining portion 23 of the operating member 2 in the locked position faces the positioning portion 611. The positioning portion 611 extends into the retaining portion 23 under the action of the second elastic member 63, thereby locking the operating member 2 in the locked position. When released, the release button 62 presses the engaging member 61 to cause the positioning portion 611 of the engaging member 61 to overcome the elastic force of the second elastic member 63 and exit the retaining portion 23. After being released, the operating member 2 slides to the unlocking position under the action of the first elastic member 5. At this time, the retaining portion 23 of the operating member 2 is staggered from the positioning portion 611. Preferably, the engaging member 61 is annular in structure, the positioning portion 611 is formed by extending from the engaging member 61 toward the retaining portion 23 of the operating member 2, the second elastic member 63 and the release button 62 are respectively located on the outside of the engaging member 61, and the second elastic member 63 and the release button 62 are arranged relative to each other, thereby making the arrangement of the components more compact.

[0072] In summary, please refer to Figures 1 to 10 , the working process of the shaking table of the first embodiment is described in detail:

[0073] When the swing of the rocking table needs to be locked, the rocking table in a horizontal state makes the suspension rod 200c in a vertical state and the swing rod 4 in a horizontal state (see the rocking table in a horizontal state). Figures 2 to 3 As shown in the figure, the operating member 2 is pressed downward so that the operating member 2 in the unlocking position overcomes the elastic force of the first elastic member 5 and slides downward along the second sliding groove 12 to the locking position. At the same time, the long hole 21 of the operating member 2 slides downward relative to the fixing seat 1 and drives the locking member 3 to slide along the first sliding groove 11 to the engaging portion 41 of the swing rod 4, and engages with the engaging portion 41 to lock the swing of the swing rod 4 (the rocking bed in the locked state is shown in the figure). Figures 8 to 9As shown in the figure), the rocking of the rocking bed is locked. When the operating member 2 slides to the locked position, the retaining portion 23 of the operating member 2 faces the positioning portion 611. The positioning portion 611 extends into the retaining portion 23 under the action of the second elastic member 63, thereby locking the operating member 2 in the locked position and keeping the locking member 3 and the rocker 4 in the locked state at the same time. When the rocking bed needs to be unlocked, the unlocking button 62 is pressed, and the unlocking button 62 presses the engaging member 61 so that the positioning portion 611 of the engaging member 61 overcomes the elastic force of the second elastic member 63 and exits the retaining portion 23. After being unlocked, the operating member 2 slides from the locked position to the unlocked position under the action of the first elastic member 5 (the rocking bed in the unlocked state is shown in the figure). Figures 2 to 3 As shown), at the same time, the elongated hole 21 of the operating member 2 slides upward relative to the fixed seat 1 and drives the locking member 3 to slide along the first sliding groove 11 away from the engaging portion 41 of the rocking rod 4, and unengages the engaging portion 41 to release the swing of the rocking rod 4, thereby allowing the rocking bed to swing freely relative to the fixed seat 1.

[0074] See also Figures 11 to 20 The structure of the rocking table of the second embodiment is basically the same as that of the rocking table of the first embodiment, and the difference lies in the holding mechanism. The difference is as follows:

The elastic protrusion 64 is elastically restored and locked in the engaging notch 651. The elastic protrusion 64 is elastically deformed under the push of the exit inclined surface 653 and moves to the reset surface 654 to exit the engaging notch 651 ( Fig. 20 The direction indicated by the middle arrow O is the moving direction of the elastic protrusion 64), and the elastic protrusion 64 moves along the reset surface 654 to the driving inclined surface 652 to release the lock ( Fig.14 The track indicated by the middle arrow P is the reset track of the elastic protrusion 64). Since the reset surface 654 is not in the same plane as the action surfaces of the driving inclined surface 652, the exit inclined surface 653 and the engaging notch 651, when the elastic protrusion 64 slides to the reset surface 654 under the pressure and guidance of the exit inclined surface 653, the operating member 2 rises and resets under the action of the first elastic member 5. In this process, the elastic protrusion 64 resets to the side close to the locking block 65 under the action of elastic recovery and just presses against the reset surface 654 to rise to reset to the driving position. The elastic protrusion 64 is provided with an inclined surface 652, so that the elastic protrusion 64 just avoids the obstruction of the exit inclined surface 653, the engaging notch 651 and the sliding guide surface 655 in the process of rising and resetting. The user only needs to press the operating member 2 in the unlocking position once to lock the elastic protrusion 64 in the engaging notch 651 of the locking block 65 to lock the operating member 2 in the locking position. Pressing the operating member 2 in the locking position again can make the elastic protrusion 64 exit the engaging notch 651 to reset the operating member 2 to the unlocking position. The structure is simple and the operation is convenient. Preferably, the reset surface 654 is perpendicular to the action surfaces of the driving inclined surface 652, the sliding guide surface 655 and the engaging notch 651 respectively, and the reset surface 654 intersects with the exit inclined surface 653, so as to facilitate guiding the elastic protrusion 64 to the reset surface 654.

[0076] In this embodiment, please refer to Figures 11 to 14 The driving inclined surface 652 is inclined along the vertical direction of the fixing seat 1, and the elastic protrusion 64 has a first matching inclined surface 641 for elastically abutting against the driving inclined surface 652. The first matching inclined surface 641 is parallel to the driving inclined surface 652. The mutual cooperation between the first driving inclined surface 652 and the driving inclined surface 652 can make the elastic protrusion 64 move to the engaging notch 651 more smoothly under the pressure of the driving inclined surface 652; please refer to Fig.11 as well as Figure 19 to Figure 20The exit slope 653 is inclined along the front-to-back direction of the fixed seat 1, and the exit slope 653 is inclined along the direction indicated by the arrow O. The elastic protrusion 64 has a second mating slope 642 for elastically abutting against the exit slope 653. The second mating slope 642 is parallel to the exit slope 653. The mutual cooperation between the second driving slope 652 and the exit slope 653 can make the elastic protrusion 64 more smoothly exit the engaging notch 651 and move to the reset surface 654 under the pressure and guidance of the exit slope 653. It can be understood that the manufacturer can flexibly adjust the relative inclinations of the driving slope 652, the sliding guide surface 655, the engaging notch 651, the exit slope 653 and the reset surface 654 as needed, so it is not limited to this. Preferably, a plurality of elastic protrusions 64 are provided and together form a quadrilateral structure, and correspondingly, a plurality of locking blocks 65 are provided and together form a quadrilateral structure. In this embodiment, four elastic protrusions 64 and four locking blocks 65 are provided, but this is not limited thereto.

[0077] In summary, please refer to Figures 11 to 20 , the working process of the shaking table of the second embodiment is described in detail:

[0078] When it is necessary to lock the swing of the rocking bed, the rocking bed in a horizontal state makes the suspension rod 200c in a vertical state and the rocking rod 4 in a horizontal state, and the operating member 2 is pressed downward so that the operating member 2 in the unlocking position overcomes the elastic force of the first elastic member 5 and slides downward along the second sliding groove 12 to the locking position. At the same time, the elongated hole 21 of the operating member 2 slides downward relative to the fixed seat 1 and drives the locking member 3 to slide along the first sliding groove 11 to the engaging portion 41 of the rocking rod 4, and engages with the engaging portion 41 to lock the swing of the rocking rod 4, thereby locking the swing of the rocking bed. In the process of the operating member 2 sliding from the unlocking position to the locking position, the first matching inclined surface 641 of the elastic protrusion 64 is elastically deformed in the direction away from the locking block 65 under the push of the driving inclined surface 652 (see the state Figure 15 to Figure 16 ), the elastic protrusion 64 moves into the engaging notch 651 under the guidance of the sliding guide surface 655, and the elastic protrusion 64 is offset toward the direction close to the locking block 65 under the action of elastic recovery and is locked in the engaging notch 651 to be locked (see the state Figure 17 to Figure 18 ), thereby locking the operating member 2 in the locking position and locking the locking member 3 and the rocking rod 4 at the same time; when the rocking bed needs to be locked, the release button 62 is pressed again, and the second matching inclined surface 642 of the elastic protrusion 64 is elastically deformed in the direction close to the operating member 2 under the push of the exit inclined surface 653, and the elastic protrusion 64 moves to the reset surface 654 to exit the engaging notch 651 (see the state Figure 19 to Figure 20 ), the unlocked operating member 2 moves along the Fig.14The trajectory shown by the arrow P in the figure slides from the locking position to the unlocking position. During this process, the elastic protrusion 64 is reset to the side close to the locking block 65 under the action of elastic recovery and just presses against the reset surface 654 to rise to reset to the driving inclined surface 652, so that the rocking table can swing freely relative to the fixed base 1. Therefore, the elastic protrusion 64 just avoids the obstruction of the exit inclined surface 653, the engaging notch 651 and the sliding guide surface 655 in turn during the process of rising and resetting.

[0079] Except for the above differences, the rest are the same as those of the first embodiment, so they will not be described again.

[0080] See also Figures 21 to 32 The structure of the rocking table of the third embodiment is basically the same as that of the rocking table of the first embodiment, and the difference lies in the holding mechanism. The difference is as follows:

[0081] In this embodiment, please refer to Figure 21 to Figure 22 The retaining mechanism 6c includes a positioning member 66 pivotally connected to the fixing seat 1 and a positioning groove 67 opened on the operating member 2. The positioning groove 67 has a snap-fitting recess 671. The positioning member 66 is snapped into the snap-fitting recess 671 to lock the operating member 2 in the locked position. The positioning member 66 withdraws from the snap-fitting recess 671 to release the operating member 2. The operating member 2 is reset to the unlocked position under the action of the first elastic member 5. Specifically, one end of the positioning member 66 is pivotally connected to the fixing seat 1, and the other end of the positioning member 66 has an extension portion 661 extending into the positioning groove 67. The extension portion 661 is arranged along the front-to-back direction of the fixing seat 1, and the length of the extension portion 661 matches the depth of the positioning groove 67. The positioning groove 67 also includes a first guide channel 672 for guiding the operating member 2 from the unlocking position to the locking position and a second guide channel 673 for guiding the operating member 2 from the locking position to the unlocking position. The first guide channel 672 is connected to the engaging recess 671, and the positioning member 66 is engaged with the engaging recess 671 under the guidance of the first guide channel 672; the second guide channel 673 is connected to the locking recess 671. 73 is connected with the engaging recess 671, and the positioning member 66 is disengaged from the engaging recess 671 under the guidance of the second guide channel 673. When locked, the operating member 2 slides downward under the pressure, and the positioning member 66 slides from the bottom of the positioning groove 67 to the engaging recess 671 of the positioning groove 67 under the guidance of the first guide channel 672 and engages with the engaging recess 671, thereby locking the operating member 2 in the locked position. The operating member 2 is pressed again, and the positioning member 66 withdraws from the engaging recess 671 under the guidance of the second guide channel 673 and slides to the bottom of the positioning groove 67 to reset the operating member 2 from the locked position to the unlocked position. The structure is simple and the operation is convenient. Preferably, the positioning groove 67 is heart-shaped, and the positioning member 66 is a guide iron hook, but it is not limited to this.

[0082] In summary, please refer to Figures 21 to 32 , the working process of the shaking table of the third embodiment is described in detail:

[0083] When the swing of the rocking bed needs to be locked, the rocking bed in a horizontal state makes the suspension rod 20c in a vertical state and the swing rod 4 in a horizontal state (see the state). Figure 21 to Figure 22 ), press the operating member 2 downward so that the operating member 2 in the unlocking position overcomes the elastic force of the first elastic member 5 and slides downward along the second sliding groove 12 to the locking position. At the same time, the elongated hole 21 of the operating member 2 slides downward relative to the fixing seat 1 and drives the locking member 3 to slide along the first sliding groove 11 to the engaging portion 41 of the rocking rod 4, and engages with the engaging portion 41 to lock the swing of the rocking rod 4, thereby locking the rocking bed. In the process of the operating member 2 sliding from the unlocking position to the locking position, the positioning member 66 slides from the bottom of the positioning groove 67 to the engaging recess 671 of the positioning groove 67 under the guidance of the first guide channel 672 and engages with the engaging recess 671, thereby locking the operating member 2 in the locking position (status see Figure 23 to Figure 28 ), thereby locking the operating member 2 in the locking position and locking the locking member 3 and the rocking rod 4 at the same time; when the rocking bed needs to be released from the rocking, the release button 62 is pressed again, and the positioning member 66 is guided by the second guide channel 673 to withdraw from the engaging recess 671 and slide to the bottom of the positioning groove 67 to reset the operating member 2 from the locking position to the unlocking position (see the state Figure 29 to Figure 32 as well as Figure 21 to Figure 22 ), so that the rocking bed can rock freely relative to the fixed seat 1.

[0084] Except for the above differences, the rest are the same as those of the first embodiment, so they will not be described again.

[0085] Compared with the prior art, since the swing locking structure 100 of the present invention is provided with an operating member 2, a locking member 3 and a rocking rod 4 connected to a rocking body, the locking member 3 is movably arranged between the fixing seat 1 and the operating member 2, and the locking member 3 locks or releases the swing of the rocking rod 4 under the drive of the operating member 2. In other words, the operating member 2 can drive the locking member 3 to move on the fixing seat 1, and lock or release the swing of the rocking rod 4 by the activity of the locking member 3, thereby locking or releasing the rocking body connected to the rocking rod 4. Only the operating member 2, the locking member 3 and the rocking rod 4 are needed to release or lock the swing of the rocking body, and the structure is simple, the cost is low and it is easy to operate.
