Description

Technical Field

[0001] The invention relates to the technical field of cabinet handles, and in particular to a cabinet telescopic handle mechanism and a use method thereof. Background Art

[0002] The cabinet handle mechanism in cabinets, wardrobes, drawer cabinets, electrical cabinets and other cabinets is not just a simple opening and closing tool, it also carries the functionality and aesthetics of the cabinet design. Its main function is to help users easily open and close cabinet doors or drawers, while avoiding stains left by direct contact with the cabinet surface. In addition to basic operating functions, the cabinet handle also needs to be able to withstand a certain amount of tension. Some handle designs also have anti-slip functions to ensure stability and safety during use. In terms of structure, the cabinet handle is usually composed of a handle body, fixings, contact surfaces, anti-slip designs, and decorative elements. The handle body can be divided into metal, plastic, wood, etc. according to different materials. Each material has its own advantages and disadvantages. Metal materials are widely used because of their durability, while plastic handles are often used in low-priced furniture because they are light and economical. The fixings are used to firmly connect the handle to the cabinet body, and the anti-slip design ensures that the handle is not easy to slip during use through surface texture or coating, thereby improving safety. The existing cabinet handle technology and usage methods are basically the same, that is, they withstand the pulling force applied by the user and conform to the natural laws of human hand movements. However, they still need to be used in conjunction with locks during use to lock the cabinet body and the cabinet door. That is, the lock core, latch and other mechanisms use mechanical principles, the hardness of the metal and complex unlocking mechanisms to prevent the door leaf from opening, and the cabinet handle is only a structure that bears pulling and pushing forces, and cannot provide a similar mechanical structure to fix the cabinet door or resist the action of external forces. That is to say, the cabinet handle itself does not have the function of locking the cabinet door when used independently. At this time, the cabinet door may be accidentally opened due to external force, impact or user's mistaken pulling, resulting in loss or damage of items. Summary of the invention

A pin rod 9 is fixed on the outer wall of the slide 8 close to the front base 1. One end of the pin rod 9 penetrates the outside of the front base 1. The top of the slide 8 is provided with an elastic telescopic self-retracting rod structure 10 interconnected with one side of the bottom end of the square-mouth swing arm 5. The elastic telescopic self-retracting rod structure 10 is used to force the square-mouth swing arm 5, the straight groove plate 11, and the C-shaped handle 6 to bounce upwards. The fixing part 3 adopts a rectangular wing plate, which is integrally formed on the left and right outer walls of the front base 1 and the rear base 2. The interior of the rectangular wing plate is provided with a through hole for the bolt to pass through. The front base 1 and the rear base 2 are both fixed to the cabinet door panel through the fixing part 3 and the bolt. When the fixing part 3 adopts a wing plate with a through hole, the bolt passes through the wing plate and is driven into the cabinet, so that the stretching mechanism can be fixed on the cabinet door panel and remain stable; the structural design of the front base 1 and the rear base 2 provides a support point for the cabinet door, which can ensure the stability of the door panel during the opening and closing process. Its strong fixing performance reduces the shaking or instability of the cabinet door caused by frequent operation, thereby increasing the service life of the cabinet door panel; A U-shaped protrusion 4 is integrally formed at the top of the rear base 2, and a hinge shaft is installed inside the U-shaped protrusion 4, and the square-mouth swing arm 5 and the hinge shaft are mutually nested; Two straight groove plates 11 are provided, and the two straight groove plates 11 are symmetrically structured about the vertical center reference plane of the square-mouth swing arm 5. The square-mouth swing arm 5 and the straight groove plates 11 are both made of stainless steel. Two symmetrical reinforcing rods are installed between the outer walls of the opposite sides of the front base 1 and the rear base 2, and the slide seat 8 and the two reinforcing rods are slidably matched; A hollow sliding sleeve 801 is fixed inside the sliding seat 8. The hollow sliding sleeve 801 and the steel column 7 are slidably matched. The hollow sliding sleeve 801 assists the sliding seat 8 and the pin rod 9 to move in the extension direction of the steel column 7, thereby ensuring that the pin rod 9 operates smoothly when the cabinet door is opened and closed; The elastic telescopic self-retracting rod structure 10 includes a rear convex plate 1001 welded and fixed to one side of the bottom end of the square-mouth swing arm 5, a front convex plate 1003 fixed to one side of the top end of the slide seat 8, and an elastic telescopic column 1002 hingedly installed on the top end of the front convex plate 1003. The top end of the elastic telescopic column 1002 is hinged to the bottom end of the rear convex plate 1001. When the locking restriction of the trapezoidal pin locking structure 13 and the straight groove plate 11 is released by the hidden elastic push-up structure 12, the elastic telescopic column 1002 starts to reset from the compressed state, and the staff holding the The C-shaped handle 6 is held, so that the square-mouth swing arm 5, the C-shaped handle 6, and the straight groove plate 11 are flipped upwards. Since the two ends of the elastic telescopic column 1002 are connected to the square-mouth swing arm 5 and the slide seat 8 through the rear convex plate 1001 and the front convex plate 1003 respectively, when the square-mouth swing arm 5 and the C-shaped handle 6 are popped up and the user applies force to the C-shaped handle 6, the square-mouth swing arm 5, the elastic telescopic self-retracting rod structure 10, and the pin rod 9 move as a whole toward the direction of the rear base 2 until the pin rod 9 is removed from the inner side of the inner edge of the cabinet body, so that the cabinet door and the cabinet body are unlocked.

[0019] A method for using a cabinet telescopic handle mechanism of this embodiment, such as the above-mentioned cabinet telescopic handle mechanism, comprises the following steps: S101: The staff needs to extend their hands to the position of the trapezoidal pin locking structure 13 and push the two trapezoidal pin locking structures 13 located on the cabinet door. The structural design of the trapezoidal pin locking structure 13 adopts a trapezoidal pin and has an inclined sliding function. The staff needs to gently push the two pins to both sides, and the pins will withdraw from the straight groove plate 11. With the push of the trapezoidal pin locking structure 13, the hidden elastic push-up structure 12 will be compressed. The hidden elastic push-up structure 12 is elastic and is compressed and deformed to a certain extent during the operation to ensure that the trapezoidal pin locking structure 13 is smoothly separated from the locked position; S102: As the trapezoidal pin locking structure 13 and the straight slot plate 11 are separated, the elastic telescopic self-retracting rod structure 10 starts to work, and the elastic telescopic self-retracting rod structure 10 automatically pushes the C-shaped handle 6, the square-mouth swing arm 5, and the straight slot plate 11 to pop up, and the square-mouth swing arm 5 and the C-shaped handle 6 in the popped-up state are for the user to hold and open the cabinet door, and at this time, the sliding seat 8 and the pin rod 9 slide toward the direction of the rear base 2 until the end of the pin rod 9 is separated from the inner side of the inner edge of the cabinet body, so that the pin rod 9 no longer locks the cabinet door and the cabinet body; S103: After the square-mouth swing arm 5 and the C-shaped handle 6 are bounced up by the elastic telescopic self-retracting rod structure 10, the staff pulls the cabinet door to complete the cabinet door opening operation, and the door will not be stuck or blocked during the opening process, and the operation is smooth and smooth; S104: After the cabinet door is opened, the staff completes the required operations and needs to close the cabinet door and ensure that it is in a locked state again. The staff then pushes the trapezoidal pin locking structure 13 to both sides again, so that the trapezoidal pin locking structure 13 does not block the folding and resetting of the square swing arm 5, the C-shaped handle 6, and the straight groove plate 11, until the square swing arm 5, the C-shaped handle 6, and the straight groove plate 11 are folded to be parallel to the steel column 7, and then the trapezoidal pin locking structure 13 is released, so that the trapezoidal pin locking structure 13 and the straight groove plate 11 can be plugged in. At this time, the end of the pin rod 9 passes through the front base 1 again and is located on the inner side of the cabinet body edge, so that the cabinet door is in a safe locked state.

[0020] Embodiment 2, based on embodiment 1, Figure 7 and Figure 8 The hidden elastic push structure 12 includes a hollow shell 1201 fixed to one side of the top of the front base 1, a cavity 1202 arranged inside the hollow shell 1201, and two coil springs 1203 fixed inside the cavity 1202. The coil spring 1203 pushes the trapezoidal pin locking structure 13 to be plugged with the straight groove plate 11. The top of the hollow shell 1201 is provided with a rectangular lower groove 1204. The trapezoidal pin locking structure 13 includes a trapezoidal pin head 1301 slidably mounted on the outer wall of one side of the hollow shell 1201 and a trapezoidal pin head 1301 on the top. The shift block 1302 is fixed at one end, and the trapezoidal pin head 1301 extends into the cavity 1202 at one end away from the straight slot plate 11. The bottom end of the shift block 1302 is slidably matched with the rectangular lower groove 1204. When the staff operates the trapezoidal pin locking structure 13, the shift block 1302 drives the trapezoidal pin head 1301 to gradually move away from the straight slot plate 11 until the trapezoidal pin head 1301 completely withdraws from the straight slot plate 11, so that the straight slot plate 11 is not locked and restricted by the trapezoidal pin locking structure 13. In this process, the rectangular lower groove 1204 provides a sufficient area for the sliding of the shift block 1302. The top of the straight slot plate 11 is provided with a notch, and the trapezoidal pin head 1301 is slidably matched with the notch at the top of the straight slot plate 11. The trapezoidal pin head 1301 adopts an inclined surface design, so that the trapezoidal pin head 1301 can be firmly stuck when inserted into the straight slot plate 11, ensuring that the cabinet door is effectively locked when closed; When the trapezoidal pin head 1301 is pushed, it will gradually enter the cavity 1202 of the hollow shell seat 1201. At this time, the trapezoidal pin head 1301 will cause the spiral spring 1203 in the hollow shell seat 1201 to be in a compressed state, so that it can adapt to changes during the process of locking and unlocking the cabinet door, and provide thrust and compression force for the trapezoidal pin head 1301 and the shift block 1302, ensuring that the trapezoidal pin head 1301 can be separated smoothly when locked.

[0021] Before actual operation of the embodiment of the present application, the staff needs to confirm whether the cabinet door panel is completely closed and locked. When the cabinet door is closed, the trapezoidal pin locking structure 13 is inserted into the straight groove plate 11 at the end of the square-mouth swing arm 5, and the pin rod 9 passes through the outside of the front base 1 and is located on the inner side of the inner edge of the cabinet. At this time, the cabinet door panel is firmly locked. When the staff needs to open the cabinet door through the handle mechanism, the staff needs to extend their hand to the position of the trapezoidal pin locking structure 13 and push the two trapezoidal pin locking structures 13 located on the cabinet door. The structural design of the trapezoidal pin locking structure 13 adopts a trapezoidal pin with an inclined sliding function. The staff needs to gently push the two pins. Pushing to both sides, the pin will withdraw from the straight slot plate 11. With the push of the trapezoidal pin locking structure 13, the hidden elastic pushing structure 12 will be compressed. The hidden elastic pushing structure 12 is elastic and is compressed and deformed to a certain extent during the operation to ensure that the trapezoidal pin locking structure 13 is smoothly separated from the locked position. After the trapezoidal pin locking structure 13 is completely separated from the straight slot plate 11, the unlocking step is completed. Since the trapezoidal pin locking structure 13 and the straight slot plate 11 are separated, the elastic telescopic self-retracting rod structure 10 starts to play a role. The elastic telescopic self-retracting rod structure 10 automatically pushes the C-shaped handle 6, the square-mouth swing arm 5, and the straight slot plate 11 to pop up. The square-mouth swing arm 5 and C-shaped handle 6 in the pop-up state are for the user to hold and open the cabinet door, and at this time, the sliding seat 8 and the pin rod 9 slide toward the direction of the rear base 2 until the end of the pin rod 9 is separated from the inner side of the cabinet body, so that the pin rod 9 no longer locks the cabinet door and the cabinet body; after the square-mouth swing arm 5 and the C-shaped handle 6 are popped up under the action of the elastic telescopic self-retracting rod structure 10, the staff pulls the cabinet door to complete the cabinet door opening operation, and the door will not be stuck or blocked during the opening process, and the operation is smooth and smooth; after the cabinet door is opened, the staff completes the required operations, such as storing items, taking out items or cleaning, etc. When the staff has finished using it, it is necessary to close the cabinet door and ensure that it is put back in place When it is in the locked state, the staff pushes the trapezoidal pin locking structure 13 to both sides again, so that the trapezoidal pin locking structure 13 does not block the folding and resetting of the square swing arm 5, the C-shaped handle 6, and the straight groove plate 11, until the square swing arm 5, the C-shaped handle 6, and the straight groove plate 11 are folded to be parallel to the steel column 7, and then the trapezoidal pin locking structure 13 is released, so that the trapezoidal pin locking structure 13 and the straight groove plate 11 can be plugged in, and the end of the pin rod 9 passes through the front base 1 again and is located on the inner side of the cabinet body, so that the cabinet door is in a safe locked state. After the operation is completed, the staff manually checks whether the cabinet door is completely locked, that is, it is tested by slightly pulling it.

9. The cabinet telescopic handle mechanism according to claim 8, characterized in that: A notch portion is provided at the top end of the straight slot plate (11), and the trapezoidal pin head (1301) is slidably fitted with the notch portion at the top end of the straight slot plate (11).

10. A method for using a cabinet telescopic handle mechanism, comprising the cabinet telescopic handle mechanism according to any one of claims 1 to 9, characterized in that: The following steps are involved: S101: The staff member needs to extend his hand to the position of the trapezoidal pin locking structure (13) and push the two trapezoidal pin locking structures (13) located on the cabinet door. The structural design of the trapezoidal pin locking structure (13) adopts a trapezoidal pin with an inclined sliding function. The staff member needs to gently push the two pins to both sides, and the pins will withdraw from the straight groove plate (11). As the trapezoidal pin locking structure (13) pushes, the hidden elastic push-up structure (12) will be compressed. The hidden elastic push-up structure (12) is elastic and is compressed and deformed to a certain extent during the operation to ensure that the trapezoidal pin locking structure (13) is smoothly separated from the locked position; S102: As the trapezoidal pin locking structure (13) and the straight groove plate (11) are separated, the elastic telescopic self-retracting rod structure (10) starts to function, and the elastic telescopic self-retracting rod structure (10) automatically pushes the C-shaped handle (6), the square-mouth swing arm (5), and the straight groove plate (11) to pop up, and the square-mouth swing arm (5) and the C-shaped handle (6) in the popped-up state are provided for the user to hold and open the cabinet door, while at this time, the sliding seat (8) and the pin rod (9) slide toward the rear base (2) until the end of the pin rod (9) is separated from the inner side of the inner edge of the cabinet body, so that the pin rod (9) no longer locks the cabinet door and the cabinet body; S103: After the square-mouth swing arm (5) and the C-shaped handle (6) are sprung up under the action of the elastic telescopic self-retracting rod structure (10), the staff pulls the cabinet door to complete the cabinet door opening operation, and the door will not get stuck or blocked during the opening process, and the operation is smooth and smooth; S104: After the cabinet door is opened, the staff completes the required operation and needs to close the cabinet door and ensure that it is locked again. The staff then pushes the trapezoidal pin locking structure (13) to both sides again, so that the trapezoidal pin locking structure (13) does not block the folding and resetting of the square swing arm (5), the C-shaped handle (6), and the straight groove plate (11), until the square swing arm (5), the C-shaped handle (6), and the straight groove plate (11) are folded to be parallel to the steel column (7), and then the trapezoidal pin locking structure (13) is released, so that the trapezoidal pin locking structure (13) and the straight groove plate (11) can be plugged in. At this time, the end of the pin rod (9) passes through the front base (1) again and is located on the inner side of the cabinet body edge, so that the cabinet door is in a safe locked state.
