[0028] like Figure 1-7 As shown, the present invention provides a punch-free mounting member for quickly installing curtains, comprising a first shell 1 and a second shell 2. The first shell 1 is composed of a detachable upper shell and a lower shell, which is convenient for assembly and disassembly. The first shell 1 and the second shell 2 are fixedly connected by screws, which is convenient for assembly and disassembly. A power module, a transmission module and a locking module are sequentially arranged in the first shell 1. The second shell 2 is connected to a pre-positioning module, which has a telescopic adjustment length. The power module is connected to the transmission module through a screw 13, and the transmission module is connected to the locking module. The power module transmits the locking module through the transmission module to lock or unlock the pre-positioning. Module, in the unlocked state, the locking module is separated from the pre-positioning module, and the pre-positioning module can arbitrarily adjust the length of its extension from the second shell 2 within its telescopic adjustment length range. In the locked state, the locking module is locked with the pre-positioning module, and the length of the pre-positioning module extending from the second shell 2 is fixed. An electric control board 14 is also provided in the first shell 1, and the power module is electrically connected to the electric control board 14. The electric control board 14 is provided with a first stroke key 14.1 and a second stroke key 14.2. The first stroke key 14.1 and the second stroke key 14.2 are both exposed outside the first shell 1 to control the locking module to lock or unlock the pre-positioning module.

[0029] The present invention realizes elastic pre-positioning installation by having a telescopic adjustable length of the pre-positioning module, and then the power module transmits the locking module through the transmission module to lock or unlock the pre-positioning module, completing the electric installation or disassembly, which is convenient for installation, saves time and effort. In addition, by setting the exposed first stroke key 14.1 and the second stroke key 14.2, it is convenient to control the power module to drive the locking module to lock or unlock the pre-positioning module.

[0030] Among them, see Figure 3 、 4The power module includes a motor movement 3 and a reducer 4. The output end of the motor movement 3 is transmission-connected to the input end of the reducer 4. The output end of the reducer 4 is transmission-connected to the screw 13. The motor movement 3 is electrically connected to the electric control board 14. The electric control board 14 is provided with a current sensor (not shown in the figure) for sensing the working current of the motor movement 3. When in use, the first stroke key 14.1 controls the operation of the motor movement 3. The motor movement 3 transmits power to the transmission module through the reducer 4 and the screw 13, thereby driving the locking module to lock the pre-positioning module. At this time, if the motor movement 3 continues to work, its working current will increase. When the current sensor senses an increase in current, it will stop the motor movement 3 from working, thereby completing the electric punch-free installation. The second stroke key 14.2 controls the motor movement 3 to rotate in the opposite direction. The motor movement 3 transmits power to the transmission module through the reducer 4 and the screw 13, and drives the locking module to unlock the pre-positioning module, thereby completing the electric disassembly and assembly. Among them, the setting of the current sensor can monitor the working current of the motor movement 3, so as to provide a controllable locking force during the locking process, avoid the motor movement 3 from over-transmitting the locking module and damaging parts, extend the service life, and provide the power module with the optimal driving stroke, saving time and electricity.

[0031] Among them, see Figure 3 、 4 The transmission module includes a nut block 5, a transmission block 6 and a first elastic member 7. The first elastic member 7 is connected between the nut block 5 and the transmission block 6. The nut block 5 is threadedly connected to the screw 13. Extension arms 5.1 for limiting the transmission block 6 are symmetrically provided on both sides of the nut block 5. The ends of the extension arms 5.1 are protruding inwardly with a clamping block 5.2. In the natural state, the first elastic member 7 pushes the nut block 5 and the transmission block 6 away from each other, and the clamping block 5.2 is against the end face of the transmission block 6. The forward and reverse rotation of the screw 13 can drive the nut block 5 to move back and forth along the length direction of the screw 13. When the screw 13 rotates to drive the nut block When the screw 13 moves away from the power module along the length direction of the screw 13, the nut block 5 synchronously pushes the first elastic member 7, and the first elastic member 7 synchronously pushes the transmission block 6, and the transmission block 6 synchronously pushes the locking module to lock the pre-positioning module. When the screw 13 rotates to drive the nut block 5 to move toward the power module along the length direction of the screw 13, the nut block 5 pulls the transmission block 6 to move synchronously through the clamping block 5.2 on the extension arm 5.1, and the transmission block 6 drives the locking module to move synchronously to unlock the pre-positioning module. When the locking module pushes the transmission block 6 toward the power module, the first elastic member 7 can provide a certain elastic expansion space for the transmission block 6.

[0032] Among them, see Figure 3 、 4The pre-positioning module includes a top block 8, a top rod 9 and a second elastic member 10. One end of the top rod 9 is fixedly connected to the top block 8 so that the top block 8 and the top rod 9 keep moving synchronously. The other end of the top rod 9 extends into the first shell 1 and cooperates with the locking module. A cavity 2.1 for sliding the top block 8 is provided in the second shell 2. The second elastic member 10 is sleeved on the top rod 9, and one end of the second elastic member 10 is against the inner bottom surface of the cavity 2.1, and the other end is against the top block 8. Preferably, a mounting cavity 8.1 for connecting the second elastic member 10 is provided on the top block 8, and a mounting hole 8.2 is provided at the center of the bottom surface of the mounting cavity 8.1. A screw hole 9.4 is provided at the end of the top rod 9, and the mounting hole 8.2 is connected to the screw hole 9.4 by screws. A through hole 1.5 for the top rod 9 to extend into is provided on the first shell 1, and a ring block 1.6 is provided in the through hole 1.5. The top rod 9 The upper portion extending into the first shell 1 is formed with a ring protrusion 9.3 which is blocked by the ring block 1.6. In the natural state, one end of the second elastic member 10 is against the inner bottom surface of the cavity 2.1, and the other end is against the bottom surface of the installation cavity 8.1. The second elastic member 10 pushes the top block 8 to extend outward from the second shell 2, and the ring protrusion 9.3 is blocked by the ring block 1.6. At this time, the length of the top block 8 extending out of the second shell 2 is the maximum telescopic adjustment length of the pre-positioning module. During the pre-positioning installation, the curtain can be supported on the window by squeezing the top block 8 inward to compress the second elastic member 10. Since the telescopic length of the top block 8 can be flexibly adjusted, the installation adaptation range is wide, and it can be adapted to windows of various sizes, reducing the rework problem caused by incorrect installation dimensions. In addition, in order to increase the friction between the top block 8 and the window wall and improve the installation stability, an anti-slip pad can be provided on the outer end surface of the top block 8.

[0033] Among them, see Figure 3-7 The locking module includes a first locking block 11 and a second locking block 12, which are symmetrically arranged on both sides of the ejector rod 9 extending into the first shell 1. The first locking block 11 and the second locking block 12 are both movably engaged with the transmission block 6. A through hole 6.1 for avoiding the ejector rod 9 is provided at the center of the transmission block 6. When the ejector rod 9 moves along the length direction of the first shell 1, it can pass through the through hole 6.1 without being blocked by the transmission block 6. In addition, the setting of the through hole 6.1 can also play a role in the movement of the ejector rod 9. To ensure the stable movement of the ejector rod 9 along the axial direction, the top and bottom surfaces of the first locking block 11 are each provided with at least one first guide block 11.1, and the top and bottom surfaces of the second locking block 12 are each provided with at least one second guide block 12.1. The first housing 1 is provided with a first guide hole 1.1 and a second guide hole 1.2 for sliding the first guide block 11.1 and the second guide block 12.1. The first guide hole 1.1 and the second guide hole 1.2 each include a locking position 1.3 and an unlocking position 1.4. Figure 5The locking positions 1.3 of the first guide holes 1.1 and the second guide holes 1.2 are linear and arranged along the length direction of the first housing 1. The unlocking positions 1.4 of the first guide holes 1.1 and the second guide holes 1.2 are bent and bent from the locking positions 1.3 toward the side of the first housing 1. The locking position 1.3 is away from the power module, and the unlocking position 1.4 is close to the power module. In the unlocked state, the first guide block 11.1 and the second guide block 12.1 are located at the unlocking positions 1.4 corresponding to the first guide holes 1.1 and the second guide holes 1.2, and the first locking block 11 and the second locking block 12 are separated from the push rod 9. In the locked state, the first guide block 11.1 and the second guide block 12.1 are located at the unlocking positions 1.4 corresponding to the first guide holes 1.1 and the second guide holes 1.2. 2 locking position 1.3, the first locking block 11, the second locking block 12 hold the push rod 9 tightly, preferably, the first guide block 11.1 is a group of two, arranged in a straight line, the second guide block 12.1 is a group of two, arranged in a straight line, the number of the first guide hole 1.1 is the same as that of the first guide block 11.1, and the number of the second guide hole 1.2 is the same as that of the second guide block 12.1, which can better guide the first locking block 11 and the second locking block 12 to hold or disengage from the push rod 9, the push rod 9 includes a holding section 9.1, which is located in the first shell 1, and a plurality of equally spaced teeth 9.2 are provided on both sides of the holding section 9.1, and the first locking block 11 and the second locking block 12 are provided with a first U-shaped groove 11 for the push rod 9 to pass through. .2, second U-shaped groove 12.2, the openings of the first U-shaped groove 11.2 and the second U-shaped groove 12.2 are both facing the push rod 9, and the bottom surfaces of the first U-shaped groove 11.2 and the second U-shaped groove 12.2 are provided with a first tooth surface 11.3 and a second tooth surface 12.3 that are engaged with the tooth 9.2. In the unlocked state, the first locking block 11 and the second locking block 12 are separated from the push rod 9, and the push rod 9 can move between the two opposing first U-shaped grooves 11.2 and the second U-shaped groove 12.2. In the locked state, the first locking block 11 and the second locking block 12 hold the push rod 9 tightly, and the first tooth surface 11.3 and the second tooth surface 12.3 are respectively engaged with the teeth 9.2 on both sides of the holding section 9.1. The two sides of the transmission block 6 are symmetrically extended with a clamping arm 6.2, and both sides The two clamping arms 6.2 are grouped together, making the transmission more stable. A protrusion 6.3 is provided at the end of the clamping arm 6.2. The outer walls of the first locking block 11 and the second locking block 12 are both provided with a first clamping groove 11.4 and a second clamping groove 12.4 that are clamped to the clamping arm 6.2. The ends of the first clamping groove 11.4 and the second clamping groove 12.4 are both provided with a first groove 11.5 and a second groove 12.5 that are engaged with the protrusion 6.3. The first clamping groove 11.4 and the second clamping groove 12.4 are both open on one side of the outer wall facing the first locking block 11 and the second locking block 12 to allow the clamping arm 6.2 to enter and exit. The first groove 11.5 and the second groove 12.5 are both open on one side of the outer wall facing the first locking block 11 and the second locking block 12 to allow the protrusion 6.3 to enter and exit.3 in and out, the cooperation of the protrusion 6.3 and the first groove 11.5 and the second groove 12.5 can play an axial limiting role on the first locking block 11 and the second locking block 12, ensuring that the first locking block 11 and the second locking block 12 move axially synchronously with the transmission block 6, and the first clamping groove 11.4, the second clamping groove 12.4, the first groove 11.5, and the second groove 12.5 are all open on one side of the outer wall of the first locking block 11 and the second locking block 12, so that the first locking block 11 and the second locking block 12 will not be hindered by the transmission block 6 when they move radially. The so-called radial movement refers to the first locking block 11 and the second locking block 12 approaching the push rod 9 or moving away from the push rod 9. When the screw 13 rotates, the nut block 5 is driven along the length of the screw 13. When the first locking block 11 and the second locking block 12 are axially moved, the first guide block 11.1 and the second guide block 12.1 move along the first guide hole 1.1 and the second guide hole 1.2 from the unlocking position 1.4 to the locking position 1.3. During the movement, the first locking block 11 and the second locking block 12 are radially close to each other to clamp the ejector rod 9, so that the first locking tooth surface 11.3 and the second locking tooth surface 12.3 are respectively engaged with the locking teeth 9.2 on both sides of the clamping section 9.1, thereby locking the ejector rod 9 and preventing it from moving. When the first locking block 11 and the second locking block 12 approach each other radially, the clamping arm 6.2 and the protrusion 6.3 will not completely slide out of the corresponding first clamping groove 11.4, the second clamping groove 12.4, the first groove 11.5, and the second groove 12.5, so that the first locking block 11 and the second locking block 12 always maintain axial synchronous movement with the transmission block 6, but do not affect the radial movement of the first locking block 11 and the second locking block 12. When the screw 13 rotates to drive the nut block 5 to approach the power module along the length direction of the screw 13, the nut block 5 pulls the transmission block 6 to move synchronously through the clamping block 5.2 on the extension arm 5.1, and the transmission block 6 pulls the first locking block 11 and the second locking block 12 to move synchronously axially through the protrusion 6.3 on the clamping arm 6.2. As the first and second locking blocks 11, 12 move axially, the first and second guide blocks 11.1, 12.1 move along the first and second guide holes 1.1, 1.2 from the locked position 1.3 to the unlocked position 1.4. This movement causes the first and second locking blocks 11, 12 to move radially away from each other, thereby disengaging from the push rod 9. The first and second locking tooth surfaces 11.3, 12.3 respectively disengage from the locking teeth 9.2 on either side of the clamping section 9.1, thereby unlocking the push rod 9. When the first and second locking blocks 11, 12 move radially away from each other, the clamping arms 6.2 and protrusions 6.3 return to their corresponding first and second slots 11.4, 12.4, and first and second grooves 11.5, 12.5.

[0034] Among them, see Figure 3 、 4 The first elastic member 7 and the second elastic member 10 are both springs. The elastic force of the first elastic member 7 is greater than that of the second elastic member 10. The first elastic member 7 is short and thick with a large elastic force, while the second elastic member 10 is slender with a small elastic force. The setting of the second elastic member 10 is convenient for squeezing the top block 8 to achieve rapid pre-positioning installation, and the small elastic force makes it convenient to squeeze and adjust the telescopic length. The setting of the first elastic member 7 can further play a role in elastic stroke compensation, especially long-term fixed installation is prone to deformation and loosening, and the first elastic member 7 can be elastically displaced at any time to prevent the curtain from falling off after a long installation time.

[0035] During installation, connect the punch-free mounting piece to one end of the curtain rod, then squeeze the top block 8 to the appropriate extended length to support the curtain on the window to complete the pre-positioning installation, press the first stroke key 14.1 to drive the motor movement 3 to work, the motor movement 3 drives the reducer 4 and the screw 13, the screw 13 drives the nut block 5 away from the power module along the length direction of the screw 13, the nut block 5 synchronously pushes the first elastic member 7, the first elastic member 7 synchronously pushes the transmission block 6, the transmission block 6 synchronously pushes the first locking block 11 and the second locking block 12 to move axially, and when the first locking block 11 and the second locking block 12 are moving axially, the first guide block 11.1 and the second guide block 12.1 follow the first guide hole 1.1 and the second guide hole 1.2 from the unlocking position 1.4 to the locking position. 1.3 direction, during the movement, the first locking block 11 and the second locking block 12 are radially close to each other until the clamping rod 9 is clamped, and the first clamping tooth surface 11.3 and the second clamping tooth surface 12.3 are respectively engaged with the clamping teeth 9.2 on both sides of the clamping section 9.1, so that the locking rod 9 cannot move. At this time, the motor movement 3 continues to work, which will cause the nut block 5 to further compress the first elastic member 7. The clamping block 5.2 on the nut block 5 is separated from the end face of the transmission block 6, and the working current of the motor movement 3 increases. When the current sensor senses the increase in current, it will stop the motor movement 3 from working, thereby completing the punch-free installation of the curtain. The electric installation saves time and effort, and after the curtain is installed for a long time, not only can the elastic stroke compensation of the second elastic member 10 be obtained, but also the first elastic member 7 can be obtained. Elastic stroke compensation can prevent the problem of curtains falling off easily after a long installation time, and the first elastic member 7 and the second elastic member 10 are assembled in different sections of the coaxial line. On the one hand, it can save effort when pre-positioning and installing, and there is no need to squeeze the second elastic member 10 too hard. On the other hand, it can ensure the curtains are installed stably for a longer time and extend the installation life. In addition, the motor movement 3 sequentially transmits the reducer 4, the screw 13, the nut block 5, the transmission block 6, the first locking block 11, and the second locking block 12 to lock the top rod 9, and the current sensor senses the working current of the motor movement 3 to control the operation of the motor movement 3, so that the motor movement 3 can provide a controllable locking stroke. On the one hand, it can avoid the motor movement 3 from damaging components due to excessive transmission, and provide a stable The controlled locking force also provides the motor movement 3 with an optimal drive stroke, shortening the transmission distance and facilitating fast locking, thus improving installation efficiency, saving time and energy, and enabling the selection of a smaller power motor movement 3, resulting in lower costs. Furthermore, the motor movement 3 sequentially transmits the transmission to the reducer 4, screw 13, nut block 5, transmission block 6, first locking block 11, and second locking block 12 to lock the top rod 9, resulting in a shorter overall length and adapting to smaller curtains for punch-free electric installation. To disassemble, the second travel key 14.2 is pressed to activate the motor movement 3. The motor movement 3 then rotates the transmission reducer 4 and screw 13 in the opposite direction. The screw 13 then drives the nut block 5 along the length of the screw 13 toward the power module, whereupon the nut block 5 passes through the block 5 on the extension arm 5.1.2 pulls the transmission block 6 to move synchronously. The transmission block 6 pulls the first and second locking blocks 11, 12 to move axially synchronously via the protrusion 6.3 on the clamping arm 6.2. As the first and second locking blocks 11, 12 move axially, the first and second guide blocks 11.1, 12.1 move along the first and second guide holes 1.1, 1.2 from the locking position 1.3 to the unlocking position 1.4. During this movement, the first and second locking blocks 11, 12 move radially away from each other, thereby disengaging from the ejector pin 9. The first and second engaging tooth surfaces 11.3, 12.3 respectively disengage from the engaging teeth 9.2 on either side of the clamping section 9.1, thereby unlocking the ejector pin 9 and completing the removal.
