DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0032] See also Figures 1 to 14, is a liftable curtain rack according to an embodiment of the present invention, which is installed on a wall for lifting and locking the curtain rod 99. The liftable curtain rack includes two fixed support devices 10 for liftable rods and a lifting device 90 for driving the curtain rod 99 to move up and down. The lifting device 90 includes a rocker mechanism 91, a steel wire rope 92 connected to the rocker mechanism 91, and a plurality of fixed pulleys 93 for the steel wire rope 92 to overlap. Each fixed support device 10 for a liftable rod includes two support blocks 20 arranged opposite to each other, a connection cover 30 connected to the top of the support blocks 20, a clamping mechanism 40 clamped between the support blocks 20, a locking mechanism 50 installed on the inner side of the support blocks 20, a latch 60 located below the locking mechanism 50, and a limiter 70; the limiter 70 is installed on the inner side of the support block 20 and located below the locking mechanism 50; the latch 60 is located between the locking mechanism 50 and the limiter 70; the clamping mechanism 40 includes a slide bar 41 slidably arranged between the two support blocks 20, an elastic member 42 arranged between the slide bar 40 and the connection cover 30, a connecting rod mechanism 43 connecting the slide bar 41, and two clamping claws 44 connecting the connecting rod mechanism 43; a card slot 410 is provided on the side of the slide bar 41; the locking mechanism 50 includes a base 51 connected to the support block 20, a stopper 52 slidably arranged on the base 51, and a stopper spring 53 clamped between the stopper 52 and the base 51.

[0033] Furthermore, when the sliding rod 41 is pulled upward by the lifting device 90 to move the curtain rod 99 upward, the thrust generated drives the clamping claws 44 to move together and clamp until the stopper 52 is embedded in the slot 410 to lock the clamping mechanism 40; when the sliding rod 41 is pulled upward by the lifting device 90 to move the curtain rod 99 further upward, the thrust generated by the curtain rod 99 drives the stopper 52 to exit the slot 410 and drives the latch 60 to be clamped between the stopper 52 and the side of the sliding rod 41; when the sliding rod 41 moves downward under the action of the elastic member 42, the clamping claws 44 are released and the latch 60 is driven downward.

[0034] Furthermore, the fixed support device 10 for the liftable rod and the liftable curtain frame of the present invention can automatically fix and self-lock the raised curtain rod 99 through the clamping mechanism 40 and the locking mechanism 50 of the fixed support device 10 for the liftable rod; when it needs to be lowered, the fixed support device 10 for the liftable rod can be unlocked through the lifting device 90 and restored to the initial state, which is easy to use, safe and reliable.

[0035] Please see Figures 1 to 7 Furthermore, the fixed support device 10 for the liftable rod is used to provide a stable locking effect on the curtain rod 99. Each fixed support device 10 for the liftable rod also includes a fixing frame 80, which is used to connect the support block 20 and fix it on the wall.

[0036] Furthermore, each support block 20 is provided with a guide rail 21 protruding from the inner side surface facing the clamping mechanism 40, and the guide rail 21 extends from bottom to top. The cross section of the guide rail 21 is U-shaped, and a strip groove 210 is provided in the middle portion for a portion of the slide bar 41 to be embedded so as to slide up and down. The base 51 of the locking mechanism 50 is fixed in the middle portion of the support block 20, and the stopper 52 is provided corresponding to the strip groove 210 and inwardly exceeds the inner side surface of the guide rail 21 under the action of the stopper spring 53. The connecting cover 30 is respectively connected to the top of the two support blocks 20, and is located above the guide rail 21 and the clamping mechanism 40. A through hole (not marked in the figure) is provided in the middle portion of the connecting cover 30 for the slide bar 41 to pass through. In this embodiment, the connecting cover 30 is integrally processed with one of the support blocks 20.

[0037] Furthermore, the slide bar 41 of the clamping mechanism 40 is penetrated from front to back to form a receiving groove 415 for the connecting rod mechanism 43 to be embedded. The card slot 410 penetrates the slide bar 41 from left to right and is connected with the receiving groove 415. In this embodiment, the card slot 410 is arranged in a T shape; the card slot 410 includes a transverse groove portion 412 located at the upper part and a vertical groove portion 414 connected to the lower edge of the middle part of the transverse groove portion 412, and the width of the transverse groove portion 412 is greater than the width of the vertical groove portion 414. A guide rod 45 extends upward from the top of the slide bar 41, and the guide rod 45 passes through the through hole of the connecting cover 30; the elastic member 42 is a spring sleeved on the guide rod 45, and the two ends of the elastic member 42 are respectively abutted against the top of the slide bar 41 and the bottom of the connecting cover 30.

[0038] Furthermore, the link mechanism 43 includes a middle rod 430 connected to the slide rod 41 and two branch connecting rods 435 pivotally connected to the two ends of the middle rod 430; one of the clamping jaws 44 is pivotally connected to the lower end of one branch connecting rod 435, and the other clamping jaw 44 is pivotally connected to the lower end of the other branch connecting rod 435; each clamping jaw 44 is arranged in an arc shape; the middle and upper parts of each clamping jaw 44 are pivotally connected to the support block 20 through a connecting shaft. In this embodiment, when the two clamping jaws 44 are close to each other, they form a circular clamp to wrap and clamp the curtain rod 99.

[0039] Furthermore, the end of the stopper 52 facing the slide bar 41 has an introduction surface 520, which is inclined inward and downward. The side of the stopper 52 facing away from the slide bar 41 is provided with a slot 525, and the base 51 extends a guide column 510 toward the slot 525 of the stopper 52; the two ends of the stopper spring 53 respectively abut against the base 51 and the bottom of the slot 525 of the stopper 52 to provide elastic force to push the stopper 52 away from the base 51.

[0040] Furthermore, the opposite sides of the end of the stopper 52 facing the slide bar 41 are provided with latching spaces 529. When the slide bar 41 is forced to continue to move upward, the stopper 52 is driven to exit the latching slot 410 and the latch 60 is driven upward, and the latch 60 is latched in the latching space 529 of the stopper 52. Specifically, ribs 527 are laterally protruded on the front and rear sides of the stopper 52, and the end of each rib 527 facing the slide bar 41 is shorter than the end of the stopper 52 facing the slide bar 41, so as to form a latching space 529 for the latch 60 to be inserted when it is raised.

[0041] Furthermore, the latch 60 includes a lap rod 61 and a locking rod 62 extending upward from both ends of the lap rod 61. The latch 60 extends a protrusion 63 toward the slide bar 41, and the protrusion 63 is correspondingly embedded in the card slot 410; specifically, the protrusion 63 extends from the middle of one side of the lap rod 61 toward the card slot 410. The width of the block 52 is smaller than the width of the horizontal groove 412 and larger than the width of the vertical groove 414, so the block 52 can be inserted into the horizontal groove 412 but cannot be inserted into the vertical groove 414. The width of the protrusion 63 is smaller than the width of the vertical groove 414, so the protrusion 63 can move up and down in the horizontal groove 412 and the vertical groove 414.

[0042] Furthermore, in the present embodiment, there are two locking mechanisms 50 , which are respectively located on two opposite sides of the clamping mechanism 40 ; there are two latches 60 , which are respectively located on two opposite sides of the clamping mechanism 40 and below the stopper 52 .

[0043] Furthermore, the stopper 70 is installed inside the support block 20 and below the locking mechanism 50; the latch 60 is clamped between the locking mechanism 50 and the stopper 70; when the slide bar 41 moves downward under the action of the elastic member 42 and drives the latch 60 to move downward, the latch 60 moves downward to the stopper 70. In this embodiment, there are two stoppers 70, which are respectively fixed at the lower end of the guide rail 21 of the support block 20; it can be understood that in other embodiments, the stopper 70 can be made integrally with the corresponding support block 20.

[0044] Please see Figure 8 and Fig. 9 Further, at this time, the liftable curtain frame is in the initial state, and the curtain rod 99 gradually rises but has not yet contacted the slide bar 41. At this time, the slide bar 41 is away from the locking mechanism 50 under the downward push of the elastic member 42, and specifically, the card slot 410 is away from and located below the stopper 52.

[0045] Please see Fig.10Furthermore, when the curtain rod 99 gradually rises under the action of the lifting device 90, it first enters between the clamping claws 44, then contacts the lower end of the slide bar 41, pushes the slide bar 41 to slide upward relative to the support block 20 and compresses the elastic member 42. When the stopper 52 is first squeezed by the slide bar 41 and moves closer to the base 51, when the stopper 52 faces the slot 410, it is embedded in the slot 410 under the action of the stopper spring 53 to lock the clamping mechanism 40. At this time, the slide bar 41 drives the clamping claws 44 to rotate through the connecting rod mechanism 43 during the upward sliding process to close and clamp the curtain rod 99, thereby achieving a self-locking state.

[0046] Furthermore, when the curtain rod 99 needs to be unlocked and lowered, the curtain rod 99 is driven upward, and the curtain rod 99 pushes the slide bar 41 to continue to rise a short distance. Since the width of the vertical groove 414 at the lower part of the slot 410 is smaller than the width of the stopper 52, the stopper 52 is squeezed by the slide bar 41 and moves horizontally toward the base 51, thereby exiting the horizontal groove 412 to achieve unlocking; then, as shown in FIG. Fig.11 As shown, the slide bar 41 continues to rise a short distance, driving the latch 60 upward to be inserted into the latch space 529 through the protrusion 63, thereby maintaining the unlocked state of the block 52; due to the action of the block spring 53, the block 52 will clamp the top of the locking rod 62 of the latch 60, thereby ensuring that the latch 60 will not fall off temporarily.

[0047] Further, such as Fig.12 and 13 As shown in FIG. 1 , due to the action of the latch 60, the stopper 52 is always in the unlocked state; then, the lifting device 90 drives the curtain rod 99 to move downward in the reverse direction, and during the downward sliding process of the slide bar 41, the connecting rod mechanism 43 drives the clamping claw 44 to rotate backward to release the clamping of the curtain rod 99, and the curtain rod 99 gradually withdraws completely downward from the clamping claw 44, and under the action of the elastic member 42, the slide bar 41 continues to slide downward until the upper edge of the transverse groove portion 412 abuts against the protrusion 63 of the latch 60, as shown in FIG. Fig.14 As shown, the slide bar 41 drives the latch 60 to move downward, so that the latch 60 exits the latching space 529 and the stopper 52 is reset; and the latch 60 stops moving downward under the obstruction of the limit member 70, and also prevents the slide bar 41 from continuing to slide down, so that the fixed support device 10 for the lifting rod returns to the initial state.

[0048] The liftable curtain rack of the present invention automatically fixes and self-locks the raised curtain rod 99 through the clamping mechanism 40 and the locking mechanism 50 of the liftable rod fixing support device 10; when it needs to be lowered, the liftable rod fixing support device can be unlocked through the lifting device 90 and restored to the initial state, which is convenient, safe and reliable to use. The present invention also protects the liftable rod fixing support device 10.

[0049] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
