Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to an electric punch-free installation device for installing curtains 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 in use. They are basically supported on the window frame 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 makes the installation troublesome, time-consuming and laborious.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0031] like Figure 1-5As shown, the utility model provides an electric punch-free installation device for installing curtains, comprising a shell 1, one end of which is connected to an end cover 2, a cavity 1.1 is provided in the shell 1, a power piece 3, a clamping assembly and an elastic adjustment assembly are sequentially installed in the cavity 1.1 from the end away from the end cover 2 to the end cover 2, the power piece 3 is fixed in the cavity 1.1, the power output end of the power piece 3 is transmission-connected to the clamping assembly, one end of the elastic adjustment assembly is abutted against the clamping assembly, and the other end is abutted against the end cover 2, the end of the elastic adjustment assembly abutting against the end cover 2 partially passes through the end cover 2 and is exposed outside the shell 1 for pre-positioning, the elastic adjustment assembly has an elastic telescopic stroke, and the power piece 3 drives the clamping assembly to clamp or release the elastic adjustment assembly.

[0032] The utility model realizes pre-positioning installation by the elastic adjustment component having an elastic telescopic stroke, and then the power piece 3 electrically controls the clamping component to press the elastic adjustment component to complete the fixed installation. When disassembling, the power piece 3 electrically controls the clamping component to release the elastic adjustment component, so that the elastic adjustment component can be elastically telescopic to adjust the length, thereby realizing the disassembly of the curtain. In this process, the power piece 3 is electrically used to complete the locking and unlocking, and there is no need for manual operation by people. It is easy to use and saves time and effort.

[0033] Among them, see Figure 3 , 4 When the power piece 3 drives the screw rod 4 to rotate clockwise, the slider 5 on the screw rod 4 moves along the thread toward the elastic adjustment component, thereby compressing the elastic telescopic stroke of the elastic adjustment component and playing a locking role. The pre-positioned installation can be further locked and fixed without manual locking, and the operation is convenient. When the power piece 3 drives the screw rod 4 to rotate counterclockwise, the slider 5 on the screw rod 4 moves along the thread toward the power piece 3, thereby releasing the elastic telescopic stroke of the elastic adjustment component and playing an unlocking role, so that the elastic adjustment component can be adjusted in length within a certain range, which is convenient for disassembly.

[0034] Among them, see Figure 2 , 34. The elastic adjustment component includes a push rod 6 and a first spring 7 and a second spring 8 sleeved on the push rod 6. A baffle 9 is provided between the first spring 7 and the second spring 8. An annular protrusion 6.1 is provided on the push rod 6. In a natural state, one end of the first spring 7 abuts against the annular protrusion 6.1, and the other end abuts against the baffle 9. One end of the second spring 8 abuts against the baffle 9, and the other end abuts against the slider 5. The annular protrusion 6.1 abuts against the end cover 2 to form an axial limit. A portion of the push rod 6 passes through the end cover 2 and is exposed outside the housing 1 for pre-positioning. For example, by pressing the push rod 6 exposed outside the housing 1 against the installation wall, the length of the push rod 6 extending out of the housing 1 can be adjusted by the elastic expansion and contraction of the first spring 7 and the second spring 8 for pre-positioning installation. Then, the power piece 3 drives the screw rod 4 to link the slider 5 to squeeze or release the first spring 7 and the second spring 8 to achieve locking and unlocking.

[0035] Among them, the elastic force of the second spring 8 is greater than the elastic force of the first spring 7, the first spring 7 is slender, and the second spring 8 is thick and short. The first spring 7 has a small elastic force and a large elastic adjustment length range. The adjustment length is mainly suitable for the telescopic length of the pre-positioned installation of the top rod 6. The second spring 8 has a large elastic force and a small elastic adjustment length range. The adjustment length can play a role in compensating for the deformation caused by long-term use during fixed installation, thereby preventing the curtain from falling off after a long installation time. For example, 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 6, it is easy to lose the elastic force after a long installation, resulting in the problem of the curtain falling off. When the elastic force is too large, the telescopic length adjustment of the top rod 6 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 7 and the second spring 8 are used in superposition, which can not only facilitate the pre-positioned installation and adjustment of the telescopic length of the top rod 6, but also prevent the problem of the curtain falling off after a long installation time, and the service life is longer and safer.

[0036] Among them, see Figure 3 , 4 , 5, the slider 5 is provided with a center hole 5.1 for avoiding the push rod 6, and the screw rod 4 is provided with a center channel 4.1 for avoiding the push rod 6. When the push rod 6 moves back and forth along its own length direction, the center hole 5.1 and the center channel 4.1 can allow the push rod 6 to move unimpeded, the screw rod 4 is provided with an external thread 4.2, and the slider 5 is provided with an internal thread 5.2 that cooperates with the external thread 4.2. The slider 5 makes a reciprocating linear motion along the length direction of the screw rod 4 through the cooperation of the internal thread 5.2 and the external thread 4.2.

[0037] Among them, see Figure 2 , 34, the power part 3 is a motor, the motor includes a movement and a reducer, the motor provides power for the rotation of the screw rod 4, a circuit board 10 is arranged in the housing 1, the motor is electrically connected to the circuit board 10, a current sensor 11 is arranged on the circuit board 10, when the current sensor 11 senses that the working current of the motor is greater than the set value, the circuit board 10 controls the motor to stop working, the setting of the current sensor 11 can allow the motor to provide a controllable locking force, because the tighter the first spring 7 and the second spring 8 are compressed, the greater the elastic force generated, and the motor needs a larger working current, therefore, the working current of the motor can be sensed by the current sensor 11 to control the motor to provide a controllable locking force, and the screw rod 4 will not be over-driven to link the slider 5 to squeeze the first spring 7 and the second spring 8.

[0038] like Figure 6-8 As shown, a top beam installation assembly includes a top beam 12 and the electric punch-free installation device as described above, the electric punch-free installation device is installed at one end of the top beam 12, and the two ends of the top beam 12 are respectively connected with a first cover 13 and a second cover 14, the definition of the second cover 14 not only includes ordinary components for shielding the end of the top beam 12, but also includes components connected to the end of the top beam 12 and having a shielding effect on the end of the top beam 12, such as the ends of a driving device, a transmission device, a power supply device, etc. The first cover 13 is fixedly connected to the electric punch-free installation device. Preferably, the first cover 13 is detachably connected to the end cover 2, and a top block 15 is slidably provided on the first cover 13, and the top block 15 is connected to the top cover 1 exposed outside the outer shell 1. The elastic adjustment component is connected to abut the installation wall to achieve pre-positioning. Preferably, the top block 15 is connected to the end of the top rod 6 exposed outside the outer shell 1, which can increase the contact surface with the installation wall. The first cover 13 is provided with a mounting cavity 13.1 for the top block 15 to slide linearly. The mounting cavity 13.1 is provided with a through hole 13.2 for the elastic adjustment component exposed outside the outer shell 1 to penetrate. Preferably, the through hole 13.2 can be passed through by the top rod 6 exposed outside the outer shell 1. This structural arrangement facilitates replacement of the first cover 13, the second cover 14 and the top block 15, so that the electric punch-free installation device is adapted to different types of top beams 12, with more flexible assembly and a wide range of applications. It can also realize rapid electric punch-free installation of curtains, saving time and effort.

[0039] When in use, the electric punch-free installation device is connected to the first cover 13 and the top block 15, and then plugged into one end of the top beam 12, and the second cover 14 is connected to the other end of the top beam 12. The curtain body can be installed under the top beam 12. First, the end of the top beam 12 with the top block 15 is pressed against the installation wall, and then the other end of the top beam 12 is pressed against the opposite installation wall. The elastic force of the first spring 7 and the second spring 8 is used to push the top rod 6 outward, so that the top beam 12 is pre-positioned and installed on the window frame, and then the motor is driven to work. The motor drives the screw rod 4 to rotate, so that the slider 5 slides along the screw rod 4 toward the direction of the second spring 8, thereby squeezing the first spring 7 and the second spring 8. When the current sensor 11 senses that the working current of the motor reaches a predetermined value, the circuit board 10 controls the motor to stop working, thereby compressing the first spring 7 and the second spring 8. The motor can provide a controllable locking force according to the preset working current value, and can realize electric operation, saving time and effort. In actual use, the elastic force of the second spring 8 can compensate for the deformation caused by long-term use in the fixed installation, so as to prevent the sliding block 5 from falling off after a long installation time. In addition, when disassembling, the driving motor rotates in the opposite direction, and the motor drives the screw rod 4 to rotate, so that the sliding block 5 slides along the screw rod 4 away from the second spring 8, thereby releasing the first spring 7 and the second spring 8, unlocking the push rod 6, so that the push rod 6 has an adjustable length range, so that the top beam 12 can be removed from the window frame. In the process of locking and unlocking the push rod 6, the sliding block 5 is driven to move back and forth by the motor, and there is no need for manual operation. It is easy to use and saves time and effort.
