Description

Technical field

[0001] The present utility model relates to the technical field of furniture fittings, in particular a rotary and sliding mechanism that can be opened by pressing. State of the art

[0002] Corner rotating cabinets are widely used in interior spaces due to their efficient use of corner space. Existing rotating and sliding mechanisms typically include a fixing plate attached to the cabinet body, a rotating plate attached to the cabinet body, and a connecting plate between the two, enabling a combined sliding and rotating motion. The user must open the cabinet body by pulling on a handle or by engaging a concealed recessed grip on the cabinet body, which has obvious disadvantages: Firstly, mounting a visible handle on the cabinet body surface detracts from the appearance, while providing a concealed recessed handle weakens the strength of the front panel, reduces internal storage space, and still requires searching for and operating the recess to open the cabinet, which is not convenient enough. Secondly, with a completely handle-free minimalist design, the user has no point of leverage to apply force when opening, resulting in a poor user experience. Therefore, there is a need for a mechanism that can trigger automatic opening by simply pressing the cabinet body without an external handle, in order to improve ease of use and space utilization. Content of the utility model

[0003] The purpose of the present utility model is to overcome the disadvantages of the prior art and to provide a rotary and sliding mechanism that can be opened by pushing, with a refined structure, simple operation and without an external handle.

[0004] To achieve the aforementioned objective, the present utility model employs the following technical solution: A rotary and sliding mechanism, which can be opened by pressing, comprising a fixing plate, a rotary plate, and a connecting plate arranged between the two, wherein the connecting plate is slidably connected to the fixing plate. The rotary and sliding mechanism further comprises a pressure actuation assembly arranged on the fixing plate. The pressure actuation assembly is in drive connection with the connecting plate and is switchable between an energy storage and locking state and a release and drive state.

[0005] In the initial state of the rotary and sliding mechanism, the pressure actuation assembly is in the energy storage and locking state.

[0006] When the connecting plate is moved by external pressure, the pressure actuation assembly is triggered to switch from the energy storage and locking state to the release and drive state.

[0007] In the release and drive state, the pressure actuation assembly drives the connecting plate to move, and the connecting plate takes the rotary plate with it to move relative to the fixing plate.

[0008] Preferably, the pressure actuation assembly comprises a sliding block, an elastic element, a pivot lever, and a pawl. The sliding block is slidably mounted on the fixing plate and is in drive connection with the connecting plate. The elastic element is connected at one end to the sliding block and at the other end to the fixing plate, thus providing an elastic driving force that drives the sliding block. The central portion of the pivot lever is rotatably connected to the fixing plate. One end of the pawl is pivotally connected to one end of the pivot lever. In the energy storage and locking state, the other end of the pawl interacts with the sliding block.

[0009] Preferably, a detent groove is formed in the sliding block, and in the energy storage and locking state, the other end of the pawl engages in the detent groove.

[0010] Preferably, the pressure actuation assembly further comprises a release element. The release element is rotatably mounted on the fixing plate and is located between the sliding block and the pivot lever. When the sliding block is carried and moved by the connecting plate, the release element is forced to rotate, and the release element in turn presses the joint area between the pivot lever and the pawl, thereby releasing the pawl from its engagement with the sliding block.

[0011] Preferably, a first actuating block is provided on the connecting plate and a second actuating block is provided on the sliding block. The first actuating block and the second actuating block are in contact with each other. When the connecting plate is moved by pushing, the second actuating block pushes the second actuating block to move the sliding block synchronously. When the pressure actuation assembly is in the release and actuation state, the sliding block pushes the first actuating block through the second actuating block to move the connecting plate synchronously.

[0012] Preferably, the elastic element is a tension spring. An adjustment mechanism for setting the elastic force of the tension spring is provided on the fixing plate. The adjustment mechanism comprises an adjusting screw and an adjusting element, wherein the adjusting screw is threaded in engagement with the adjusting element, the adjusting element is connected to the tension spring, and when the adjusting screw is turned, the adjusting element can be driven into an axial movement.

[0013] Preferably, the pressure actuation assembly further comprises a positioning base. The positioning base is fixedly arranged on the fixing plate, and at least two sliding pins are provided on the positioning base. Corresponding guide holes are formed in the sliding block through which the sliding pins are guided.

[0014] Preferably, a return contact section is provided at the end of the pivot lever opposite the pawl. After the rotary plate has been driven into motion, the connecting plate contacts and drives the return contact section, causing the pivot lever to rotate. This, in turn, moves the pawl back into its return position and presses the sliding block, compressing the elastic element and returning it to the energy storage and locking state.

[0015] Preferably, a roller is rotatably arranged on the return contact section.

[0016] The beneficial effects of the present utility model include: 1. The user simply needs to lightly press and release the rotating cabinet body to trigger the push-action assembly, which automatically extends the cabinet body in a rotating motion. This achieves a truly handle-free design with a clean appearance and smooth user experience. 2. The minimal pressure displacement of the connecting plate releases the mechanical locking mechanism, and the elastic potential energy of the pressure actuation assembly drives the movement of the rotating cabinet body, with fast response and reliable function. 3. The functions pressure release, energy storage, locking, release, drive, guidance and automatic reset are integrated into a compact modular assembly, thus saving installation space. 4. The preload force of the elastic element can be finely adjusted via the adjustment structure to adapt to different weights of the rotating cabinet body or user preferences regarding the ejection force. 5. The push-button actuator assembly can automatically return to its original locking state while the user continues to open the rotating cabinet body, thus being ready for the next opening by pressing, thereby forming a complete work cycle and making it convenient to use. 6. The precise fit of the guide pins and guide holes ensures stable movement. The return contact section uses a roller design that converts sliding friction into rolling friction, reducing wear and noise.

Detailed description

[0018] With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. 8. The present utility model provides a rotary and sliding mechanism that can be opened by pressing. As in Fig. As shown in Figure 1, the rotary and sliding mechanism mainly comprises a fixing plate 10, a rotary plate 20, a connecting plate 30, and a pressure actuation assembly 40. The fixing plate 10 serves to attach it to the cabinet body, and the rotary plate 20 serves to connect it to the cabinet body to be opened. The connecting plate 30 is arranged between the fixing plate 10 and the rotary plate 20 and is slidably connected to the fixing plate 10 via a guide rail (not shown in the figure), allowing it to move back and forth in a horizontal direction. Simultaneously, the connecting plate 30 is movably connected to the rotary plate 20 via mechanisms such as connecting rods or sliding grooves (not shown in the figure), thereby converting the rotary movement of the rotary plate 20 into a linear movement of the rotary plate 20.

[0019] As in Fig. 3 and Fig.As shown in Figure 4, the pressure actuation assembly 40 is fixedly mounted on the fixing plate 10. Specifically, the pressure actuation assembly 40 comprises a sliding block 41, a tension spring as an elastic element 42, a release element 43, a pivot lever 44, a pawl 45, and a positioning base 46.

[0020] The sliding block 41 is the main motion and energy storage component. Specifically, the positioning base 46 is fixedly attached to the fixing plate 10 by means of screws, and two sliding pins 47 are arranged side by side on it. Two guide holes 413 are formed in the sliding block 41, into which the sliding pins 47 are inserted, thus forming a stable and reliable two-point guide pairing that ensures that the sliding block 41 can slide uniformly only in the specified direction, without tilting or jamming.

[0021] The drive connection between the sliding block 41 and the connecting plate 30 is realized via actuating blocks. Specifically, a first actuating block 31 is provided on the connecting plate 30, and a second actuating block 411 is provided on the sliding block 41. The first actuating block 31 and the second actuating block 411 are in contact with each other. This design causes the following: When the connecting plate 30 is moved inwards by pushing, the first actuating block 31 pushes the second actuating block 411 and moves the sliding block 41 inwards with it. Conversely, when the sliding block 41 is driven outwards, the second actuating block 411 pushes the first actuating block 31 and moves the connecting plate 30 outwards with it.

[0022] The elastic element 42 is a tension spring, one end of which is connected to the sliding block 41 and the other end of which is connected to the adjusting element 52 of the adjusting structure 50. The adjusting structure 50 comprises an adjusting screw 51 and an adjusting element 52, the adjusting element 52 being threaded in engagement with the adjusting screw 51. By turning the adjusting screw 51, the adjusting element 52 can be moved back and forth, thereby changing the initial extension of the tension spring and enabling stepless fine adjustment of the ejection force. In its initial state, the tension spring is stretched and has stored elastic potential energy.

[0023] The locking function is implemented by the pivot lever 44 and the locking pawl 45. Specifically, the central section of the pivot lever 44 is rotatably connected to the fixing plate 10 via a pivot axis. One end of the locking pawl 45 is pivotally connected to one end of the pivot lever 44 via a pivot pin. A detent groove 412 with a guide chamfer is formed in the sliding block 41. The free end of the locking pawl 45 engages in the detent groove 412 of the sliding block 41 under the action of the pivot lever 44. At this point, the sliding block 41 is reliably locked by the mechanical blocking of the locking pawl 45, even though the tension spring 42 attempts to pull it outwards. The entire pressure actuation assembly 40 is in the energy storage and locking state, meaning it is "tensioned and ready," and the connecting plate 30 and the rotating cabinet body are in the closed position.

[0024] The release element 43 is L-shaped overall, with its corner region rotatably connected to the fixing plate 10 via a pivot axis. Specifically, one arm of the release element 43 is in contact with the sliding block 41, and the other arm is in contact with the joint area between the pivot lever 44 and the locking pawl 45.

[0025] At the other end of the pivot lever 44, the end facing away from the pawl 45, a return contact section is formed. A roller 48 is rotatably mounted on the return contact section, which converts the sliding friction between the connecting plate 30 and the pivot lever 44 into rolling friction, thus reducing wear and noise. Operating principle

[0026] Pressure release and unlocking (switching from energy storage and locking state to release and drive state): When the user gently pushes the rotating cabinet body, the cabinet body engages the rotating plate 20 and the connecting plate 30, moving them a short distance inwards. The connecting plate 30, via the first actuating block 31, pushes the second actuating block 411 of the sliding block 41, causing the sliding block 41 to move inwards synchronously. This inward movement of the sliding block 41 pushes the corresponding arm of the release element 43, causing the release element 43 to rotate counterclockwise around its pivot point. The other arm of the release element 43 pivots accordingly and pushes the pivot point between the pivot lever 44 and the locking pawl 45, forcing the pivot lever 44 to rotate clockwise. The rotation of the pivot lever 44 takes the pawl 45 with it and lifts it upwards, so that its end protrudes a certain distance from the detent groove 412 of the sliding block 41.This releases the mechanical locking mechanism of the sliding block 41.

[0027] Automatic drive and extension (release and drive status): At the moment the sliding block 41 is unlocked, the elastic potential energy stored in the continuously stretched tension spring 42 is immediately released, generating a strong tensile force that rapidly pulls the sliding block 41. The sliding block 41, via its second actuating block 411, forcefully pushes the first actuating block 31 of the connecting plate 30, taking the connecting plate 30 with it, which then moves rapidly outwards. The linear outward movement of the connecting plate 30 is converted, via its connection mechanism with the rotary plate 20, into a combined rotary and sliding movement of the rotary plate 20. This causes the rotating cabinet body to rotate smoothly and be partially extended outwards, placing it in an open position convenient for the user to store and retrieve items. At this stage, the push-actuating assembly 40 is in the release and drive state.

[0028] Automatic reset and relocking: When the user wants to fully open or close the rotating cabinet body, they pull or push it further. As the connecting plate 30 moves outwards along with the rotating cabinet body to a certain position, its first action block 31 contacts the roller 48 at the end of the pivot lever 44. As the connecting plate 30 continues to move, it forces the pivot lever 44 to rotate counterclockwise via the roller 48. The rotation of the pivot lever 44 produces two coupled effects: On the one hand, via its pivot point with the pawl 45, it pushes the release element 43 back to its starting position, causing it to rotate clockwise. On the other hand, it engages the pawl 45 and moves it inwards.The movement of the pawl 45 ultimately pushes the sliding block 41, which is already in the outer position, inwards against the tensile force of the tension spring 42 until the end of the pawl 45 again engages in the detent groove 412 of the sliding block 41. At this point, the sliding block 41 is locked again, the tension spring 42 is stretched again and stores energy, and the entire push-act assembly 40 has fully returned to its energy-storage and locking state and is ready for the next opening by pressing.
