Description

Technical Field

[0001] The present invention relates to the technical field of lifting blackout curtains, and in particular to an installation structure and an installation method of a lifting blackout curtain. Background Art

[0002] The existing lifting blackout curtain generally places the lifting actuator of the lifting blackout curtain directly in the frame profile with a mounting groove, the open side of the frame profile is provided with a cover plate that is buckled with it, and the bottom of the frame profile is provided with a through hole for the traction rope to pass through.

[0003] For example, the Chinese invention patent with application number CN202011160408.7 discloses a rechargeable magnetically driven hollow glass built-in blinds, which has an upper horizontal frame cavity in the length direction of the upper horizontal frame and on the side facing the inner glass. The blind lifting and curtain flipping actuators are arranged in the upper horizontal frame cavity, and a cover plate is provided at the position corresponding to the front cavity opening of the upper horizontal frame cavity, that is, the cavity opening on the side facing the inner glass.

[0004] However, the installation structure of this lifting blackout curtain requires a cover plate that is buckled with the frame profile. When the frame profile and the cover plate are cut at the splicing angle, due to the poor force-bearing capacity of the frame profile and the cover plate, the two ends of the frame profile and the cover plate are easily deformed when cutting the splicing angle, and when the horizontal frame profile is connected to the vertical frame profile, the position near the seam is prone to unevenness, affecting the overall installation effect.

[0061] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0062] like Figure 1 and Figure 2 As shown, the present invention provides an embodiment of a mounting structure for a lifting shade curtain 2, comprising a window frame 1 and a lifting shade curtain 2, wherein the window frame 1 is provided with a receiving cavity for accommodating the lifting shade curtain 2, the window frame 1 comprising a top mounting frame 11 and side mounting frames 12a, 12b, the top mounting frame 11 and the side mounting frames 12a, 12b being cylindrical structures with both ends open, the top mounting frame 11 being provided with a top assembly cavity, the side mounting frames 12a, 12b being provided with side assembly cavities, the top mounting frame 11 and the side mounting frames 12a, 12b being connected by top angle brackets 13 extending into the top assembly cavity and the side assembly cavity; Figure 3 and Figure 4 The top mounting frame 11 is provided with a wheel seat mounting hole 111 which is connected to the top assembly cavity. A dimming wheel seat 14 is fixed in the wheel seat mounting hole 111. The dimming wheel seat 14 is provided with a first guide mechanism. The top angle code 13 is provided with a second guide mechanism. A lifting drive slider 15 adapted to it is slidingly provided in the side assembly cavity. A lifting traction rope 21 extends from the top of the lifting blackout curtain 2. The lifting traction rope 21 passes around the first guide mechanism and the second guide mechanism in turn and is connected to the lifting drive slider 15. A fixed hanger 16 is provided at the bottom end of the side assembly cavity, and the lifting drive slider 15 can be hung with the fixed hanger 16.

[0063] The top mounting frame 11 and the side mounting frames 12a and 12b of this embodiment are arranged into a cylindrical structure surrounded by each other and connected by the top angle code 13. On the one hand, the strength of the top mounting frame 11 and the side mounting frames 12a and 12b is better than that of the frame profile that needs to be buckled with the cover plate, and it is not easy to deform when the two ends are spliced at an angle; on the other hand, the ends of the top mounting frame 11 and the side mounting frames 12a and 12b have a good shaping effect under the support of the top angle code 13, and are less likely to deform; thereby facilitating the assembly and smooth operation of components such as the lifting drive slider 15; the dimming wheel seat 14 is connected to the top mounting frame 1 1 is snapped into the wheel seat mounting hole 111 set on the top, and the dimming wheel seat 14 can be assembled directly from the outside of the top mounting frame 11, which is convenient for installation; the first guide mechanism and the second guide mechanism are respectively arranged in the dimming wheel seat 14 and the top angle bracket 13, and can be modularly assembled with the dimming wheel seat 14 and the top angle bracket 13 respectively; the first guide mechanism and the second guide mechanism guide the lifting traction rope 21 to the corner position, and the lifting drive slider 15 can more smoothly pull the lifting traction rope 21 to drive the lifting blackout curtain 2 to rise and fall, or be hung with the fixed hanger 16 to keep the lifting blackout curtain 2 in a stable raised state.

[0064] Combine Figure 5 and Figure 6 The first guide mechanism of this embodiment includes a first traction wheel 141 and a second traction wheel 142. The first traction wheel 141 is arranged on the upper side of the second traction wheel 142. The first traction wheel 141 and the second traction wheel 142 are used to allow the vertical lifting traction rope 21 to pass around the first traction wheel 141 and the second traction wheel 142 in sequence and then wrap out horizontally.

[0065] The bottom of the top mounting frame 11 is provided with a receiving groove 112 arranged parallel to the top assembly cavity. The lower portion of the second traction wheel 142 of the first guide mechanism extends into the receiving groove 112 and is blocked by the side wall of the receiving groove 112. Figure 7 The side mounting frame 12a, on which the lift drive slider 15 is mounted, is provided with a wire groove 121 / wire hole that communicates with the receiving groove 112. The lift rope 21, which has passed around the second traction wheel 142, passes through the receiving groove 112 and the wire groove 121 / wire hole in sequence and enters the side assembly cavity. This eliminates the need for the lift rope 21 to pass through the top assembly cavity, facilitating its routing.

[0066] The top corner bracket 13 of this embodiment includes two detachably connected corner bracket bodies 131, and the second guide mechanism is connected to the two corner bracket bodies 131. Figure 6As shown, the second guide mechanism includes a one-way roller 132 and guide wheels 133 provided on both sides of the one-way roller 132. The lifting rope 21 is sequentially wound in and out of the one-way roller 132 and the two guide wheels 133 on the opposite side. The one-way roller 132 can only rotate in the direction of raising the lifting shade 2. When the lifting drive slider 15 pulls the lifting rope 21 downward, the lifting rope 21 can smoothly pull the lifting shade 2 upward. When the lifting shade 2 tends to slide downward under the action of gravity, since the one-way roller 132 cannot rotate in the reverse direction, there is a strong friction between the lifting rope 21 and the one-way roller 132, and the lifting rope 21 will not be pulled in the reverse direction, thereby preventing the lifting shade 2 from automatically sliding downward and maintaining the lifting shade 2 at a certain height.

[0067] Combine Figure 8 , the top angle code 13 of this embodiment is provided with two pins, and one side of the angle code body 131 is provided with an elastic arm 134 corresponding to the pins, the elastic arm 134 bulges toward the surface of the pin and is connected to the side of the pin close to the free end, and the elastic arm 134 is preferably in contact with the cavity wall on the back side of the end of the top mounting frame 11 or the side mounting frames 12a, 12b, so as to press the angle code body 131 against the cavity wall on the front side of the top mounting frame 11 or the side mounting frames 12a, 12b, and the pressure of the angle code body 131 acts evenly on the cavity wall on the front side of the top mounting frame 11 or the side mounting frames 12a, 12b, so that the top mounting frame 11 connected by the top angle code 13 is flush with the cavity wall on the front side of the side mounting frames 12a, 12b, thereby achieving the purpose of leveling the connection ends of the top mounting frame 11 and the side mounting frames 12a, 12b.

[0068] In order to reduce the sliding stroke of the lifting drive slider 15 and realize the complete lifting of the lifting shade 2, a fixing column 135 is preferably provided on the top corner code 13 of this embodiment. A wire cavity is provided on the top of the lifting drive slider 15, and a second roller 151 is provided in the wire cavity (combined with the lifting drive slider 15). Figure 9 Since the lifting and pulling ropes 21 are generally arranged in two ways, in order to prevent the lifting and pulling ropes 21 from being entangled with each other, in this embodiment, a spacer 152 is preferably provided in the wire passage cavity. The spacer 152 is provided above the second roller 151 and is arranged to cross the second roller 151 in a three-dimensional manner.

[0069] When winding the lifting rope 21, the two lifting ropes 21 passing around the second guide mechanism are passed around the second roller 151 from both sides of the partition bar 152 respectively, and then the free ends of the lifting ropes 21 are connected to the fixed column 135 of the top angle code 13.

[0070] Since the two angle code bodies 131 are detachable, the two angle code bodies 131 can be installed in coordination after the lifting rope 21 passes around the second guide mechanism and the second roller 151 and is connected to the fixing column 135, so as to facilitate the winding of the lifting rope 21.

[0071] The present invention also provides an embodiment of a mounting structure for a venetian blind. In this embodiment, the dimming wheel seat 14 is provided with a flap driven wheel 143 in the top assembly cavity, and a flap driving wheel 136 is provided in the top angle code 13. The top assembly cavity is provided with a rotating shaft for driving the flap driven wheel 143 to rotate with the flap driving wheel 136; a ladder rope 22 extends from the top of the lifting blackout curtain 2, and the ladder rope 22 is hung on the flap driven wheel 143; a flap driving mechanism for driving the flap driving wheel 136 to rotate is provided in the side assembly cavity.

[0072] The leaf-flipping drive mechanism and the lifting drive slider 15 are respectively arranged in two different side mounting frames 12a and 12b. The leaf-flipping drive mechanism includes a leaf-flipping drive slider 17, a leaf-flipping drive rope 18 and a return spring 19. A first roller is rotatably provided on the fixed hanger 16. The leaf-flipping drive slider 17 is connected to the end of the return spring 19. The leaf-flipping drive rope 18 passes around the leaf-flipping drive wheel 136 and the first roller, and the two ends are respectively fixed to the return spring 19 and the leaf-flipping drive slider 17. The leaf-flipping drive slider 17, the leaf-flipping drive rope 18 and the return spring 19 form a closed loop.

[0073] When the leaf-turning driving slider 17 is driven to slide up and down, the friction between the leaf-turning driving rope 18 and the leaf-turning driving wheel 136 will drive the leaf-turning driven wheel 143 and the ladder rope 22 thereon to rotate, thereby realizing leaf turning.

[0074] In addition, the present invention also provides an installation method for the lifting shade curtain 2, and the specific installation steps include:

[0075] (1) Pass the lifting traction rope 21 around the first guide mechanism on the dimming wheel seat 14;

[0076] (2) Engage the dimming wheel seat 14 with the wheel seat mounting hole 111 of the top mounting frame 11, and pass the lifting traction rope 21 that has passed through the first guide mechanism through the second guide mechanism of the top angle bracket 13;

[0080] (6) Slide the lifting drive slider 15 until it is connected to the fixed hanger 16;

[0081] (7) Cut off the excess length of the lifting and pulling rope 21.

[0082] When a fixed column 135 is provided on the top corner code 13, a wire-passing cavity is provided on the top of the lifting drive slider 15, a second roller 151 and a spacer 152 are provided in the wire-passing cavity, and the spacer 152 is provided above the second roller 151 and is arranged in a three-dimensional cross-arrangement with the second roller 151, the lifting traction rope 21 bypassing the second guide mechanism is connected to the lifting drive slider 15 in step (3), specifically including

[0083] The two lifting ropes 21 passing around the second guide mechanism are passed around the second roller 151 from both sides of the partition bar 152 respectively, and then the free ends of the lifting ropes 21 are connected to the fixed column 135 of the top angle bracket 13.

[0084] This can reduce the sliding stroke of the lifting drive slider 15 and facilitate subsequent lifting drive.

[0085] In this embodiment, a wire cutting hole is provided on the side mounting frame 12a and is communicated with the side assembly cavity. The wire cutting hole is provided near the fixing column 135 so as to facilitate cutting off the excess length of the lifting and pulling rope 21.

[0086] It should be noted that before performing step (6) to slide the lifting drive slider 15 until it is connected to the fixed hanger 16, the fixed hanger 16 needs to be slid into the end of the side mounting frame 12a and fixed to the side mounting frame 12a.

[0087] When the lifting shade curtain 2 is a venetian blind, the specific installation steps include:

[0088] (1) Pass the lifting traction rope 21 around the first guide mechanism on the dimming wheel seat 14, and hang the ladder rope 22 of the venetian blind on the flap driven wheel 143 of the dimming wheel seat 14;

[0089] (2) Engage the dimming wheel seat 14 with the wheel seat mounting hole 111 of the top mounting frame 11, insert the rotating shaft into the top assembly cavity, and pass through the flap driven wheel 143, and pass the lifting traction rope 21 that has bypassed the first guide mechanism around the second guide mechanism of the top angle bracket 13;

[0090] (3) Connecting the lifting traction rope 21 passing through the second guide mechanism to the lifting drive slider 15;

[0091] (4) Install the top angle bracket 13 at the end of the top mounting frame 11, install the lifting drive slider 15 from the end of the side mounting frame 12a into the side assembly cavity, and connect the side mounting frame 12b equipped with the leaf-turning drive mechanism to the other end of the top mounting frame 11 through the top angle bracket 13 equipped with the leaf-turning drive wheel 136;

[0092] (5) Connect the side mounting frame 12a provided with the lifting drive slider 15 to the top corner bracket 13 at the end of the top mounting frame 11;

[0093] (6) Slide the lifting drive slider 15 until it is connected to the fixed hanger 16;

[0094] (7) Cut off the excess length of the lifting and pulling rope 21.

[0095] In step (4), the side mounting frame 12b provided with the leaf-turning drive mechanism and the top mounting frame 11 are connected via the top angle bracket 13 provided with the leaf-turning drive wheel 136, specifically including:

[0096] Pass the leaf-turning drive rope 18 around the leaf-turning drive wheel 136 and the first roller of the fixed hanger 16, and connect the leaf-turning drive slider 17, the leaf-turning drive rope 18 and the return spring 19 end to end in sequence to form a closed loop;

[0097] Clamp the fixed hanger 16 with the fixture, and pass the side mounting frame 12b from the end of the fixture away from the fixed hanger 16 through the fixture, the fixed hanger 16, the return spring 19, the leaf-turning drive slider 17, and plug it into the top angle bracket 13 with the leaf-turning drive wheel 136. The structure after installation is as follows: Figure 10 As shown;

[0098] The top angle bracket 13 provided with the leaf-turning driving wheel 136 is plugged into the top mounting frame 11 to connect the leaf-turning driving wheel 136 to the rotating shaft.

[0099] Therefore, when the leaf-turning driving slider 17 is driven to slide up and down, the friction between the leaf-turning driving rope 18 and the leaf-turning driving wheel 136 will drive the leaf-turning driven wheel 143 and the ladder rope 22 thereon to rotate, thereby realizing leaf turning.

[0100] When the installation structure of the lifting blackout curtain 2 (including the venetian blind) also includes a bottom corner bracket and a bottom frame profile, and a bottom assembly cavity is provided in the bottom frame profile, the installation method should also include: plugging the two ends of the bottom frame profile into the bottom corner brackets respectively, and connecting the bottom frame profile to the mounting frames 12a and 12b on both sides through the bottom corner brackets.

[0101] The bottom corner bracket is also provided with an elastic arm 134, and the elastic arm 134 abuts against the cavity walls of the bottom assembly cavity and the side assembly cavity to level the connection ends of the bottom mounting frame and the side mounting frame 12a, 12b.

[0102] Combine Figure 11 The lifting drive slider 15 and the flap driving slider 17 of the present invention are both provided with a magnetic attraction part 153, a sliding wheel 154 that slides with the cavity wall of the side assembly cavity, and a first hook portion 155; the top of the fixed hanger 16 is relatively provided with a second hook portion 161 and a guide spring piece 162. The guide spring piece 162 enables the lifting drive slider 15 or the flap driving slider 17 to overcome the external magnetic attraction force and connect the first hook portion 155 with the second hook portion 161, so that the lifting blackout curtain 2 (including the blinds) can be kept in a specific working state with temperature.

[0103] In summary, the implementation of the present invention has the following beneficial effects:

[0104] 1. The top mounting frame 11 and the side mounting frames 12a and 12b are configured as a cylindrical structure surrounded by each other and connected by a top angle bracket 13. On the one hand, the top mounting frame 11 and the side mounting frames 12a and 12b are stronger than the frame profile that needs to be fastened to the cover plate, and are not easily deformed when the ends are spliced and cut at an angle. On the other hand, the ends of the top mounting frame 11 and the side mounting frames 12a and 12b have a good shaping effect under the support of the top angle bracket 13, and are less likely to deform.

[0105] 2. When the top mounting frame 11 and the side mounting frames 12a and 12b are not easily deformed, the assembly and smooth operation of the lifting drive slider 15 and other components can be facilitated;

[0106] 3. The dimming wheel seat 14 is snapped into place through the wheel seat mounting hole 111 provided on the top mounting frame 11. The dimming wheel seat 14 can be assembled directly from the outside of the top mounting frame 11, which is convenient for installation.

[0107] 4. The first guide mechanism and the second guide mechanism are respectively arranged in the dimming wheel seat 14 and the top angle bracket 13, and can be modularly assembled with the dimming wheel seat 14 and the top angle bracket 13 respectively;

[0108] 5. The first guide mechanism and the second guide mechanism guide the lifting traction rope 21 to the corner position. The lifting drive slider 15 can more smoothly pull the lifting traction rope 21 to drive the lifting shade 2 to rise and fall, or be connected with the fixed hanger 16 to keep the lifting shade 2 in a stable raised state.

[0109] 6. The elastic arms 134 corresponding to the pins on the top corner bracket 13 abut against the cavity wall, which can flatten the connection ends of the top mounting frame 11 and the side mounting frames 12a and 12b to prevent deformation, while ensuring that the lifting drive slider 15 and the leaf-turning drive slider 17 can slide more smoothly in the side assembly cavity;

[0110] 7. A receiving groove 112 is provided at the bottom of the top mounting frame 11. The lower portion of the first guide mechanism extends into the receiving groove 112. The side mounting frames 12a and 12b are provided with wire grooves 121 or wire holes communicating with the receiving groove 112, making wiring and winding very convenient.

[0111] 8. The top angle code 13 is assembled by two detachable angle code bodies 131. The second guide mechanism is connected to the two angle code bodies 131. The corresponding top angle code 13 can be assembled after the winding of the lifting traction rope 21 and the second guide mechanism, as well as the winding of the flap driving rope 18 and the flap driving wheel 136 are completed. The winding is very convenient.

[0112] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
