Description

Technical Field

[0001] The invention relates to the technical field of blinds, and in particular to a blind control structure and a blind with a self-locking function. Background Art

[0002] Insulating glass built-in blinds refer to windows that are set in a face-to-face state and sealed on all sides with blinds that can be raised and lowered as needed inside two glasses (inner glass and outer glass, also called front glass and rear glass) that are sealed on all sides. They belong to the category of sunshade insulating glass products. There are two types of control modes for insulating glass built-in blinds: one is single-operator control; the other is double-operator control. Single-operator control refers to the cooperation of an outer operator and an inner operator to realize the flipping of the blinds and the lifting of the blinds. Double-operator control refers to the control of the flipping of the blinds and the lifting of the blinds by two inner operators and two outer operators respectively.

[0003] In the related art, application number 202020696262.7 discloses a hollow glass built-in blind, comprising a frame with a blind cavity in the middle, a blind arranged in the blind cavity of the frame, and a lifting control mechanism for driving the blind to rise and fall; the blind comprises a plurality of blades and a traction rope for driving the blades to rise and fall; the lifting control mechanism comprises a traction rope roller and a retracting follower respectively arranged on the frame; the retracting follower comprises a base and a counterweight, a magnetic structure is provided at the lower part of the height direction of the base, the counterweight is arranged on the base, and the counterweight is located above the magnetic structure along the height direction of the base; a traction rope connection structure is also provided on the base; one end of the traction rope is connected to the traction rope connection structure by passing through the traction rope roller. The hollow glass built-in blind has the characteristics of good stability, easy operation and wide application range. Furthermore, it has a better limiting effect and can avoid the occurrence of traction rope entanglement. However, the above structure still has the following problems: in the process of glass sealing of the blinds (refer to Figure 1 ) or when the Venetian blinds are being transported, they need to be inverted or placed sideways. During the inversion or sideways process, the blades of the Venetian blinds will move irregularly in the hollow cavity, the blades will constantly rub against the inner surface of the glass, and adjacent blades will also scratch each other, which can easily cause the blades to deform or be damaged.

[0004] Application number CN202021866116.0 discloses a built-in blind switch mechanism and a built-in blind system with a self-locking function, including a profile frame column, a control switch assembly and an external control handle, the control switch assembly is slidably arranged inside the frame column cavity of the profile frame column, the external control handle is slidably arranged outside the profile frame column and connected to the control switch assembly, the external control handle is used to drive the lifting and lowering of the control switch assembly and the sliding of the control switch assembly along the extension direction of the length of the profile frame column inside the frame column cavity, and a self-locking mechanism is provided between the side wall surface of the control switch assembly and the frame column cavity. When the self-locking mechanism is locked, the control switch assembly and the profile frame column cannot be relatively displaced along the extension direction of the length of the profile frame column. The position of the control switch assembly can be restricted and locked by this structure. In this way, the internal blinds can be prevented from being repeatedly and violently retracted and released due to the action of external forces during transportation and installation, thereby preventing the blinds or connecting ropes from being damaged. The convex lock tongue includes at least one set of lock teeth, and the number of lock teeth can be determined according to the weight of the blinds to be locked. Each set of lock teeth is fixedly arranged on the side wall of the control switch assembly, and the lock teeth include a snap-on tip, and the recessed snap-on is arranged as a locking tooth chain matching the shape of the lock teeth. When the snap-on tip is inserted into the notch of the locking tooth chain, the locking function is realized, and the direction of the snap-on tip is perpendicular to the lifting direction of the control switch assembly. However, the above structure still has the following problems: when the snap-on tip is inserted into the notch of the locking tooth chain, the locking function is realized, and there is a disadvantage of poor locking stability. At the same time, since each set of lock teeth is fixedly arranged on the side wall of the control switch assembly, when the lock teeth are damaged, the control switch assembly needs to be replaced as a whole, and the frame column cavity needs to be modified, which has the disadvantage of poor versatility.

[0025] When the user operates the inner operator through the outer operator to make the blinds reach the desired state, the inner operator drives the lock hook assembly to move to the position corresponding to the lock seat assembly. The buckle part of the lock hook assembly gradually approaches the lock seat during the movement, and is tightly engaged with the lock seat when it reaches the predetermined position, forming a stable locked state. In the locked state, the engagement force between the buckle part of the lock hook assembly and the lock seat is sufficient to resist the interference of external forces on the blinds, ensuring that the blades maintain a stable relative position. Even if the blinds are in an inverted or sideways state, the self-locking mechanism can effectively prevent the relative movement between the blades and contact with the inner surface of the glass, thereby avoiding friction and scratches. When the user needs to adjust the state of the blinds, he only needs to reverse the inner operator through the outer operator to disengage the buckle part of the lock hook assembly from the lock seat, and then he can easily unlock and readjust the angle or position of the blinds. The unlocking process is also simple and quick, without the need for additional tools or complicated operating steps, which improves the user experience.

[0026] In addition, the clamping groove is located at the top of the connecting seat and is formed by two symmetrically arranged clamping parts (including a vertical plate and a horizontal plate). This design enables the clamping groove to firmly clamp the clamping block of the inner operator to prevent it from loosening or falling off during use. The user only needs to align the clamping block of the inner operator with the clamping groove from the side and then push it hard to achieve the clamping. This design does not require the use of additional tools or screws, which greatly simplifies the installation process. During the clamping process, the clamping block can slide smoothly into the clamping groove and is firmly clamped due to the elastic effect of the clamping parts to form a stable connection. The design of the clamping structure allows the inner operator to be directly clamped into the clamping groove of the connecting seat without additional adjustment or modification. This improves the versatility of the product, allowing the same lock hook assembly to adapt to a variety of inner operators of different specifications. Since there is no need to adjust or modify the inner operator or the blind frame, the original aesthetics of the blind can be maintained, avoiding appearance damage or incoordination that may be caused by modification.

[0027] In summary, the present invention effectively improves the stability and safety of the blinds during transportation, installation and daily use through the stable connection between the lock hook assembly and the internal operator, and the ingenious locking mechanism between the lock seat assembly and the lock hook assembly; at the same time, the design of the snap-on structure not only ensures the stable connection between the lock hook assembly and the internal operator, but also greatly simplifies the installation and maintenance process, thereby improving the versatility and aesthetics of the product.

[0044] Embodiment 1:

[0045] Please refer to Figure 2-11 As shown, this embodiment provides a blind control structure with a self-locking function, including an inner controller 30, which is used to cooperate with an outer controller to realize the flipping of the blinds and the lifting of the blinds; two clamping blocks 31 are formed at the bottom of the inner controller 30;

[0046] The shutter control structure also includes:

[0047] The lock base assembly 10 includes a fixing base 11 and a lock base 12 disposed on the fixing base 11;

[0048] The lock hook assembly 20 includes a connecting seat 21 and two elastic connecting plates 22 arranged opposite to each other. A clamping structure 23 is arranged on the top surface of the connecting seat 21. The clamping structure 23 includes two symmetrically arranged clamping members 231. The clamping member 231 includes a vertical plate 2311 and a horizontal plate 2312 extending horizontally inward along the top of the vertical plate 2311; a clamping groove 233 is formed between the two clamping members 231, and the connecting seat 21 is clamped with the two clamping blocks 31 of the inner manipulator 30 through the clamping groove 233; the upper ends of the two elastic connecting plates 22 are respectively connected to the connecting seat 21, and the inner sides of the lower ends of the two elastic connecting plates 22 are respectively formed with buckle portions 221; the buckle portions 221 of the two elastic connecting plates 22 engage or disengage with the lock seat 12 in the vertical direction during the up and down movement.

[0049] On the basis of the above structure, when the user operates the inner operator 30 through the outer operator to make the venetian blind reach the desired state, the inner operator 30 drives the lock hook assembly 20 to move to the position corresponding to the lock seat assembly 10. The buckle portion 221 of the lock hook assembly 20 gradually approaches the lock seat 12 during the movement, and is tightly engaged with the lock seat 12 when reaching the predetermined position, forming a stable locked state. In the locked state, the engagement force between the buckle portion 221 of the lock hook assembly 20 and the lock seat 12 is sufficient to resist the interference of external forces on the venetian blind, ensuring that the blades maintain a stable relative position. Even if the venetian blind is in an inverted or sideways state, the self-locking mechanism can effectively prevent the relative movement between the blades and the contact with the inner surface of the glass, thereby avoiding the occurrence of friction and scratches. When the user needs to adjust the state of the venetian blind, he only needs to reversely operate the inner operator 30 through the outer operator to disengage the buckle portion 221 of the lock hook assembly 20 from the lock seat 12, and then the angle or position of the venetian blind can be easily unlocked and readjusted. The unlocking process is also simple and quick, without the need for additional tools or complicated steps, which improves the user experience.

[0050] In addition, the clamping groove 233 is located at the top of the connecting seat 21 and is formed by two symmetrically arranged clamping members 231 (including a vertical plate 2311 and a horizontal plate 2312). This design enables the clamping groove 233 to firmly clamp the clamping block 31 of the inner manipulator 30 to prevent it from loosening or falling off during use. The user only needs to align the clamping block 31 of the inner manipulator 30 with the clamping groove 233 from the side, and then push it hard to achieve the clamping. This design does not require the use of additional tools or screws, which greatly simplifies the installation process. During the clamping process, the clamping block 31 can smoothly slide into the clamping groove 233, and is firmly clamped due to the elastic effect of the clamping member 231 to form a stable connection. The design of the clamping structure 23 allows the inner manipulator 30 to be directly clamped into the clamping groove 233 of the connecting seat 21 without additional adjustment or modification. This improves the versatility of the product, so that the same lock hook assembly 20 can be adapted to a variety of inner manipulators 30 of different specifications. Since there is no need to adjust or modify the inner operator 30 or the shutter frame, the original aesthetics of the shutter can be maintained, avoiding appearance damage or disharmony that may be caused by modification.

[0051] In summary, the present invention effectively improves the stability and safety of the blinds during transportation, installation and daily use through the stable connection between the lock hook assembly 20 and the internal operator 30, and the ingenious locking mechanism between the lock base assembly 10 and the lock hook assembly 20; at the same time, the design of the snap-in structure 23 not only ensures the stable connection between the lock hook assembly 20 and the internal operator 30, but also greatly simplifies the installation and maintenance process, thereby improving the versatility and aesthetics of the product.

[0052] In a preferred embodiment of the present invention, the lock base assembly 10 further includes an adjustment assembly 13;

[0053] A groove 111 is provided on the first side surface of the fixing seat 11;

[0054] The lock seat 12 is formed on the first side surface of the fixing seat 11 and is located above the groove 111; first guiding inclined surfaces 121 are respectively formed on two opposite side surfaces of the lock seat 12, so that the width of the lock seat 12 gradually increases from top to bottom;

[0055] The adjustment assembly 13 includes a slider 131, a guide block 132 and a return spring 133; the slider 131 can be slidably installed in the groove 111 up and down; the guide block 132 is formed on the surface of the slider 131, and the two opposite side surfaces of the guide block 132 are respectively formed with second guide inclined surfaces 1321, so that the width of the guide block 132 gradually decreases from top to bottom; one end of the return spring 133 is connected to the guide block 132, and the other end thereof is used to connect with the lock seat; when the return spring 133 is in a normal state, an accommodating space is formed between the guide block 132 and the lock seat 12, and when the return spring 133 is in a compressed state, the guide block 132 and the lock seat 12 can contact each other.

[0056] Working principle:

[0057] During actual application, the lock hook assembly 20 includes a connecting seat 21 and two relatively arranged elastic connecting plates 22, the upper ends of the two elastic connecting plates 22 are respectively connected to the connecting seat 21, and the inner sides of the lower ends of the two elastic connecting plates 22 are respectively formed with snap-fit ​​portions 221; the connection between the lock hook assembly 20 and the internal manipulator 30 allows the user to control the up and down movement of the internal manipulator 30 through the external manipulator, thereby controlling the up and down movement of the lock hook assembly 20.

[0058] Locking process:

[0059] The lock hook assembly 20 moves downward under the action of external force, and the buckle portion 221 of the elastic buckle portion contacts the first guide slope 121 of the lock seat 12. As the width of the lock seat 12 gradually increases from top to bottom, the spacing between the buckle portions 221 gradually increases, so that the buckle portions 221 can smoothly enter the accommodation space. When the buckle portion 221 is separated from the lower part of the lock seat 12, the elastic buckle portion returns to the undeformed state under the action of its own elastic restoring force, and engages with the lock seat 12 in the vertical direction to complete the locking.

[0060] Unlocking process:

[0061] The lock hook assembly 20 continues to move downward under the action of external force, and the buckle portion 221 contacts the upper sides of the guide block 132, and the distance gradually increases. When the buckle portion 221 is separated from the guide block 132, the elastic clamping portion returns to the undeformed state.

[0062] The lock hook assembly 20 moves upward under the action of external force, and the buckle portion 221 contacts the second guide slope 1321 of the guide block 132, and the distance between them gradually increases. The buckle portion 221 drives the guide block 132 to move upward until the guide block 132 contacts the lock seat 12, and the reset spring 133 is in a compressed state. Since the accommodation space between the guide block 132 and the lock seat 12 disappears, the buckle portion 221 directly transitions from contacting the guide block 132 to contacting the lock seat 12 during the upward movement. When the buckle portion 221 separates from the upper part of the lock seat 12, the elastic clamping portion returns to the undeformed state and separates from the lock seat 12 in the vertical direction, completing the unlocking.

[0063] On the basis of the above structure, the present embodiment, through the ingenious design of the lock hook assembly 20 and the lock seat assembly 10, enables the two to cooperate closely during the locking process, effectively prevents the loosening and falling off of the lock, and improves the stability of the lock. During the unlocking process, the unlocking process is smoother and more convenient through the cooperation between the guide block 132 and the buckle portion 221 and the elastic force of the reset spring 133. In addition, the present embodiment can effectively prevent the blinds from being deformed or damaged during transportation or installation through the connection between the lock hook assembly 20 and the inner manipulator 30 and the locking mechanism between the lock seat assembly 10 and the lock hook assembly 20. Even when inverted or sideways, the blades can maintain a relatively stable state, avoiding friction and scratches with the inner surface of the glass or other blades.

[0064] In a preferred embodiment of the present invention, a roller installation cavity 112 is provided on the fixing seat 11, and a flip rope transition wheel 14 is installed in the roller installation cavity 112. The flip rope transition wheel 14 is used for cooperating with the flip rope to connect.

[0065] On the basis of the above structure, the flip rope is a link connecting the venetian blind blades and the control mechanism. By pulling or releasing the flip rope, the venetian blind blades can be flipped. By the matching connection between the flip rope transition wheel 14 and the flip rope, the friction resistance of the flip rope during the movement can be reduced, the flipping efficiency can be improved, and the flipping of the venetian blind can be smoother.

[0066] In a preferred embodiment of the present invention, a first locking screw 15 is also included. A first threaded hole 113 is also provided in the groove 111 below the slider 131. The first locking screw 15 is threadedly connected to the first threaded hole 113. The first locking screw 15 is used to lock the fixing seat 11 to the shutter frame. The nut of the first locking screw 15 is used to limit the slider 131.

[0067] On the basis of the above structure, the fixing seat 11 is locked on the shutter frame by the first locking screw 15, which enhances the overall stability of the locking seat assembly 10, making the shutter more secure and reliable during use. The nut of the first locking screw 15 limits the slider 131, effectively preventing the slider 131 from moving when not needed, ensuring the normal operation and control accuracy of the shutter. Through the design of the first locking screw 15, the fixing seat 11 is quickly and easily connected to the shutter frame, reducing the difficulty and time cost of installation.

[0068] In a preferred embodiment of the present invention, a second locking screw is also included. An extension portion 114 is formed on one side of the upper portion of the fixing seat 11. A second threaded hole 115 is provided on the extension portion 114. The second locking screw is threadedly connected to the second threaded hole 115. The second locking screw is used to lock the fixing seat 11 to the shutter frame.

[0069] On the basis of the above structure, the second locking screw cooperates with the extension 114 to further enhance the stability of the fixing seat 11 on the shutter frame. The double locking mechanism enables the lock seat assembly 10 to be more firmly mounted on the shutter, thereby improving the overall stability of the shutter. The design of the extension 114 increases the contact area between the fixing seat 11 and the shutter frame, thereby improving the bearing capacity of the lock seat assembly 10. This enables the shutter to maintain its structure and function more stably when subjected to external forces.

[0070] In a preferred embodiment of the present invention, an inclined surface 116 is formed on the upper portion of the first side surface of the fixing seat 11 , and the inclined surface 116 is used to guide the lock hook assembly 20 to align with the lock seat 12 .

[0071] On the basis of the above structure, the inclined surface 116 is located at the upper part of the first side surface of the fixing seat 11. This position enables the lock hook assembly 20 to first contact the inclined surface 116 when it approaches the lock seat 12. Guided by the inclined surface 116, the lock hook assembly 20 can be more accurately aligned with the lock seat 12, thereby improving the accuracy and stability of locking. This ensures that the shutter can firmly maintain the position of the blades in the locked state to prevent them from moving or deforming. The design of the inclined surface 116 makes the docking process of the lock hook assembly 20 and the lock seat 12 smoother, reducing the difficulty and complexity of the installation process. The installer does not need to spend too much time and energy to adjust the position of the lock hook assembly 20 and the lock seat 12, thereby improving the installation efficiency.

[0072] In a preferred embodiment of the present invention, two opposite side walls of the groove 111 are respectively provided with slide grooves 117 , two opposite side walls of the slider 131 are respectively provided with slide rails 1311 , and the slider 131 is slidably engaged in the two slide grooves 117 via the two slide rails 1311 .

[0073] Based on the above structure, the close cooperation between the slide groove 117 and the slide rail 1311 ensures the stability of the slider 131 during the sliding process. Even when subjected to external force, the slider 131 can be firmly maintained in the slide groove 117 without falling off or shaking.
