Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a curtain punching-free electric installation device and a top beam installation component thereof. Background Art

[0002] Curtains are widely used in homes, offices and other places, and are mainly used to adjust indoor light. Currently, rolling blinds, venetian blinds, honeycomb blinds and the like are more commonly used. Generally, during installation, the curtains need to be fixed to the window frames by means of mounting codes and screws. Since screw installation will produce screw holes on the window frames, the curtains need to be re-drilled when they are reinstalled or replaced, and cannot be installed in situ. This will inevitably leave multiple screw holes on the wall of the window frame, which not only damages the wall but also affects the aesthetics. In addition, the punching installation will generate dust, which is inconvenient to clean and time-consuming and laborious to install. Although there are many punch-free installation curtains on the market, the existing punch-free installation components need to be manually operated when used. They are basically supported on the window frames by elastic assembly, and then the installation is completed by people manually adjusting the locking limit. Since the installation positions of the curtains mostly have a certain installation height, manual installation and adjustment require people to climb up to operate, which is time-consuming and laborious, and the installation is troublesome and the installation efficiency is low.

[0032] like Figure 1-7As shown, the utility model provides a punch-free electric installation device for curtains, including a shell 1, a accommodating chamber 1.3 is provided in the shell 1, and an electric drive module 2 for providing power, a locking module and a telescopic adjustment module are sequentially provided in the accommodating chamber 1.3, the electric drive module 2 is fixedly arranged in the accommodating chamber 1.3, one end of the locking module is connected to the power output end of the electric drive module 2, and the other end of the locking module is connected to the telescopic adjustment module, and one end of the telescopic adjustment module away from the locking module is exposed outside the shell 1 for abutting against the installation surface for pre-positioning, and the telescopic adjustment module has a telescopic adjustment length, and the electric drive module 2 transmits the locking module to lock or unlock the telescopic adjustment module. In the locked state, the length of the telescopic adjustment module extending out of the shell is fixed, and in the unlocked state, the telescopic adjustment module can arbitrarily adjust the length of the telescopic adjustment module extending out of the shell within its telescopic adjustment length range.

[0033] The utility model realizes pre-positioning installation by using the telescopic adjustment module with a telescopic adjustment length, and then drives the locking module to hold the telescopic adjustment module for fixing through the electric drive module 2 to complete the installation. When disassembling, the electric drive module 2 drives the locking module to withdraw, squeeze and elastically reset to release the hold on the telescopic adjustment module, so that the telescopic adjustment module can be telescopically adjusted in length, thereby realizing the disassembly of the curtain. In this process, locking and unlocking are completed electrically through the electric drive module 2, and manual operation is unnecessary. The use is convenient, and time and labor are saved.

[0034] Among them, see Figure 2 The shell 1 includes a main body 1.1 and an end cover 1.2 detachably connected to the main body 1.1. The end cover 1.2 is detachably connected, which is convenient for assembly and replacement to adapt to different types of curtain top beams. A limiter 13 is fixedly provided at the end of the main body 1.1. The end cover 1.2 is detachably connected to the limiter 13. The setting of the limiter 13 can play a role of medium connection and can also reduce damage to the main body 1.1. The electric drive module 2 is fixedly arranged at one end of the accommodating cavity 1.3 of the main body 1.1 away from the limiter 13. The telescopic adjustment module is provided with a blocking portion 3.1 that cooperates with the limiter 13 to prevent the telescopic adjustment module from axially escaping from the shell 1. The setting of the limiter 13 facilitates the detachable connection of the end cover 1.2 and is convenient for replacement. On the other hand, it can play a role of axial limit blocking to limit the telescopic adjustment module from axially escaping from the shell 1.

[0035] Among them, see Figure 2 , 3, 4, the telescopic adjustment module includes a push rod 3, a push block 4, and a first spring 5, and the locking module includes a screw rod 7, a first slider 8, a second slider 9 and a locking assembly. The push rod 3 is connected to the push block 4, the first spring 5, the end cover 1.2, the limiter 13, the second slider 9, and the first slider 8 in sequence from the outside to the inside. The push block 4 is fixed to the end of the push rod 3 by screws for abutting the mounting surface. The screw rod 7 is transmission-connected to the power output end of the electric drive module 2, and the first slider 8 is threadedly connected to the screw rod 7. The locking assembly is installed in the second slider 9 for holding or disengaging the push rod 3. The blocking portion 3.1 is integrally formed on the push rod 3. In the natural state, the first spring 5 is squeezed toward both ends, and one end of the first spring 5 abuts against the inner end surface of the push block 4. The other end abuts against the inner end surface of the end cover 1.2, and the blocking portion 3.1 abuts against the limit piece 13. In the natural state, the first spring 5 pushes the top block 4 to slide out of the end cover 1.2 by a maximum distance, and the maximum distance is the maximum telescopic adjustment length of the punch-free electric installation device. During adjustment, the first spring 5 can be compressed by pushing the top block 4 inward for pre-positioning installation, and then the electric drive module 2 drives the screw rod 7 to rotate, and the screw rod 7 drives the first slider 8 to move axially along the screw rod 7 to push the second slider 9, and the second slider 9 drives the locking assembly to move at the same time until the locking assembly hugs the top rod 3 to complete the locking installation. Since the telescopic length can be adjusted, the installation adaptability is relatively wide, and it can match a variety of curtain top beams to adapt to windows of various sizes, and can also realize electric installation, saving time and effort.

[0036] Among them, see Figure 3 The locking assembly includes a first clamping block 10, a second clamping block 11 and an elastic member 12. The second slider 9 is provided with a first channel 9.1 for sleeve-connecting the ejector rod 3. The second slider 9 is also provided with a second channel 9.2 which is perpendicular to the first channel 9.1 and is used to install the first clamping block 10 and the second clamping block 11. The first clamping block 10 and the second clamping block 11 are symmetrically arranged in the second channel 9.2. The ejector rod 3 passes between the first clamping block 10 and the second clamping block 11. The elastic member 12 is arranged between the first clamping block 10 and the second clamping block When the first holding block 10 and the second holding block 11 are subjected to the extrusion force in the opposite direction, the first holding block 10 and the second holding block 11 are moved closer to each other and hold the top rod 3. When the external force is removed, the elastic member 12 pushes the first holding block 10 and the second holding block 11 in the opposite direction to separate from the top rod 3. The first holding block 10 and the second holding block 11 are moved closer to and separated from each other to realize the locking and unlocking of the top rod 3. This structural setting makes the locking effect better, the structure is more stable in the locked state, the installation is more firm, and it is not easy to fall off due to long-term use. Figure 5The elastic member 12 is a spring, and two of the springs are arranged in a group between the first clamping block 10 and the second clamping block 11. The springs are symmetrically located on the upper and lower sides of the push rod 3, and can avoid the push rod 3 and will not hinder the axial movement of the push rod 3. The first clamping block 10 and the second clamping block 11 are both provided with spring grooves 10.1 and 11.1 for installing springs.

[0037] Among them, see Figure 2 , 3 6. Symmetrical extension arms 13.1 are formed on both sides of the limit member 13. Trapezoidal grooves 13.2 are concavely provided on both sides of the extension arms 13.1. Trapezoidal blocks 10.2 and 11.2 that cooperate with the trapezoidal grooves 13.2 are provided on the first clamping block 10 and the second clamping block 11. The first clamping block 10 and the second clamping block 11 are radially squeezed and pushed by the trapezoidal grooves 13.2 and the inclined surfaces of the trapezoidal blocks 10.2 and 11.2. For example, when the second sliding block 9 is squeezed and pushed forward, it will drive the first clamping block 10 and the second clamping block 11 to move together, and the inclined surfaces of the trapezoidal blocks 10.2 and 11.2 on the first clamping block 10 and the second clamping block 11 will move along the trapezoidal grooves 13.2. The inclined surface of the trapezoidal groove 13.2 slides, so that the first clamping block 10 and the second clamping block 11 are subjected to radial extrusion force and approach each other, thereby clamping the push rod 3. At this time, the spring between the first clamping block 10 and the second clamping block 11 is compressed, and when the second sliding block 9 is withdrawn from the axial extrusion, the spring between the first clamping block 10 and the second clamping block 11 pushes the first clamping block 10 and the second clamping block 11 away from each other, and the trapezoidal blocks 10.2 and 11.2 on the first clamping block 10 and the second clamping block 11 are reset to the trapezoidal groove 13.2 along the inclined surface, and the first clamping block 10 and the second clamping block 11 are disengaged from the push rod 3, and rapid locking and unlocking are achieved through radial extrusion and reset, and the structure is simple and compact.

[0038] Among them, see Figure 3 , 5 7, the mandrel 3 is provided with a clamping section 3.2, and both sides of the clamping section 3.2 are provided with a plurality of equally spaced latching teeth 3.3, the first clamping block 10 and the second clamping block 11 are provided with U-shaped grooves 10.3 and 11.3 for the mandrel 3 to pass through, and the bottom surfaces of the U-shaped grooves 10.3 and 11.3 are provided with latching tooth surfaces 10.4 and 11.4 that are engaged with the latching teeth 3.3, and in the locked state, the first clamping block 10 and the second clamping block 11 are provided with U-shaped grooves 10.3 and 11.3. The block 11 clamps the push rod 3, and the tooth surfaces 10.4 and 11.4 are clamped with the tooth 3.3 of the clamping section 3.2, thereby locking the push rod 3 from axial movement. In the unlocked state, the first clamping block 10 and the second clamping block 11 are separated from the push rod 3, and the push rod 3 can move between the two opposing U-shaped grooves 10.3 and 11.3, thereby releasing the push rod 3 for axial movement. The setting of the tooth 3.3 and the tooth surfaces 10.4 and 11.4 facilitates fast and accurate clamping.

[0039] Among them, see Figure 2 , 3 , 4, 6, 7, the telescopic adjustment module also includes a second spring 6, the second spring 6 is sleeved on the push rod 3 and is located between the first slider 8 and the second slider 9, the elastic force of the first spring 5 is less than the elastic force of the second spring 6, the first spring 5 is slender and has a small elastic force, the second spring 6 is thick and short and has a large elastic force, the setting of the first spring 5 is convenient for elastically squeezing the push rod 3 to achieve pre-positioning installation, and the small elastic force is convenient for squeezing and adjusting the telescopic length, the setting of the second spring 6 can further play a role in elastic stroke compensation, especially for long-term fixed installation The second spring 6 can be elastically displaced at any time to supplement the installation to prevent the curtain from falling off after a long installation period. For example, when the top block 4 on the top rod 3 is against the installation surface to complete the pre-installation, the electric drive module 2 drives the screw rod 7 to transmit the first slider 8 to push the second spring 6, and the second spring 6 pushes the second slider 9 until the first holding block 10 and the second holding block 11 on the second slider 9 hold the top rod 3 tightly. At this time, the first holding block 10, the second holding block 11, and the top rod 3 are locked with each other, the top rod 3 is pressed against the installation surface, and the second slider 9 is pressed against the second spring 6. The block 9 also stops moving forward, while the first slider 8 continues to move forward to squeeze the second spring 6 until it is locked, and the electric drive module 2 stops working. If a single spring is used, when the elastic force is too small, although it is convenient to pre-position and install the telescopic length of the top rod 3, it is easy to lose the elastic force after a long installation, and the service life of the elastic tight is short, and the problem of the curtain falling off is easy to occur. When the elastic force is too large, the telescopic length adjustment of the top rod 3 will be more difficult, but the installation and use time can be longer, and it is not easy to fall off. Therefore, the first spring 5 and the second spring 6 are used in a superimposed manner, which can not only facilitate the pre-positioning and installation of the telescopic length of the top rod 3, but also prevent the problem of the curtain falling off easily after a long installation time, and the service life is longer and safer. In addition, the first spring 5 and the second spring 6 are separately arranged, and the first spring 5 is arranged at the end of the top rod 3 away from the locking module, and the second spring 6 is arranged in the locking module between the first slider 8 and the second slider 9, which can reduce the driving stroke of the electric drive module 2, and the compression range is small, so that the locking time is shorter, the locking and unlocking speeds are faster, and the electric drive module 2 can choose a smaller power and lower cost.

[0040] Among them, see Figure 2 , 36. A first signal switch 14 is provided on one end of the first slider 8 close to the electric drive module 2, and a second signal switch 15 is provided on one end of the first slider 8 close to the second slider 9. The first signal switch 14 is used to sense the travel position of the first slider 8 when it retreats and unlocks, and the second signal switch 15 is used to sense the travel position of the first slider 8 when it advances and locks. When the first signal switch 14 and the second signal switch 15 sense the set travel position, the electric drive module 2 will stop working to complete unlocking and locking. The setting of the first signal switch 14 and the second signal switch 15 can allow the electric drive module 2 to provide a controllable unlocking travel and locking travel, avoid the second spring 6 being over-compressed and damaging adjacent components, can provide a controllable locking force, extend the service life, and provide the electric drive module 2 with an optimal driving travel, that is, the moving distance of the first slider 8 is controllable, avoid the electric drive module 2 over-driving the lead screw 7 to drive the first slider 8 to move, saving time and electricity.

[0041] The electric drive module 2 is a motor, which includes a movement and a reducer. The motor provides power for the rotation of the screw rod 7, which is stable and labor-saving, and realizes electric operation.

[0042] like Figure 8 As shown, a top beam installation assembly includes a top beam 16, one end of the top beam 16 is connected to the above-mentioned electric curtain punch-free installation device, the end surface of the end cover 1.2 is blocked with the end of the top beam 16, and the other end of the top beam 16 is connected to a cover 17, and the cover 17 is not limited to a cover in the ordinary sense, but also includes side ends of a motor device, a power supply device, a transmission device, etc. When the motor device, the power supply device, the transmission device and the top beam are plugged in, the end of the top beam can be shielded.

[0043] During assembly, the punch-free electric installation device for the curtain is plugged into the top beam 16, and the other end of the top beam 16 is plugged into the cover 17. The curtain body can be assembled under the top beam 16. During installation, the top block 4 is pressed against the installation wall, and the other end of the top beam 16 is pressed against the opposite installation wall. The top block 4 is subjected to the elastic squeezing force of the first spring 5 so that the top beam 16 can be supported in the installation position to complete the pre-positioning installation. Then the motor is driven to work, and the motor drives the screw rod 7 to rotate, so that the first slider 8 on the screw rod 7 slides along the screw rod 7 toward the second slider 9. The first slider 8 pushes the second spring 6 and the second slider 9, so that the first holding block 10 and the second holding block 11 in the second slider 9 are subjected to the inclined surface of the trapezoidal groove 13.2 on the limiting member 13 during the synchronous movement with the second slider 9. 2 and 3. The second spring 6 is compressed by the first slider 8 and the second spring 6 is compressed by the second signal switch 15 on the first slider 8. The second signal switch 15 on the first slider 8 senses the travel position of the first slider 8 forward and locked. Then, the motor stops working, thereby locking the push rod 3 and preventing it from moving axially. After the top beam 16 is installed for a long time, the elastic force of the second spring 6 can be adjusted. The second slider 9, the first clamping block 10, the second clamping block 11, the push rod 3, and the push block 4 are squeezed and pushed again, so that the push block 4 is always pressed against the installation wall, not easy to fall off, and the installation is stable. When disassembling, the driving motor rotates in the opposite direction, and the motor transmission screw 7 rotates in the opposite direction, so that the first slider 8 on the screw rod 7 moves away from the second slider 9 along the screw rod 7, until the first signal switch 14 on the first slider 8 senses the travel position of the first slider 8 retreating and unlocking, the motor stops working, thereby releasing the second spring 6, and the second slider 9 loses the axial squeezing force. At this time, the springs between the first clamping block 10 and the second clamping block 11 push the first clamping block 10 and the second clamping block 11 away from each other, so that the trapezoidal blocks on the first clamping block 10 and the second clamping block 11 10.2 and 11.2 are reset to the trapezoidal groove 13.2 of the limiter 13, and the first clamping block 10 and the second clamping block 11 are separated from the push rod 3, so that the push rod 3 is unlocked. The push rod 3 can be pushed to move axially by squeezing the push block 4, so that the top beam 16 is removed from the installation position. In the process of locking and unlocking the push rod 3, the first slider 8 is electrically driven by the motor to move back and forth, and the spring is reset and unlocked, without manual operation by people, which is convenient to use, saving time and effort. In addition, the second signal switch 15 on the first slider 8 can sense the travel position of the first slider 8 forward locking, so that the motor can provide a controllable locking force without excessively squeezing the second spring 6. In addition, the end cover 1.2 is detachably connected to the limiter 13 on the housing 1, and the end cover 1.2.
