[0002] In the interlocking door systems of the door and window hardware sector, existing implementations of lower-linked floor belt clamps generally employ a clamping-type fixing structure. This solution clamps the belt by mechanically compressing the belt clamp body to deform it, resulting in the application of significant operating force during installation and difficulty in accurately controlling the clamping force. Especially when the belt needs to pass through a narrow space, installation tools cannot effectively extend, often requiring repeated disassembly of adjacent hardware, significantly increasing construction time and complexity. Furthermore, once the structure is clamped, it becomes irreversibly locked. If the belt needs to be replaced due to fatigue, stretching, wear, or breakage, the belt clamp must be destructively removed, which not only damages the supporting hardware but also doubles the system maintenance cost.

[0038] To further illustrate the technical means and effects employed by the present invention to achieve its intended objectives, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0039] In the description of the present invention, it should be clarified that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence; the terms "vertical", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the devices or elements referred to must have a specific direction or position, and therefore cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0041] This embodiment provides a belt clip structure, such as Figures 1-17 As shown, the belt clip structure includes a mounting base 1, a fixing member 2 and a clamping member 3, wherein the clamping member 3 has a connecting end and a guide end, the connecting end is detachably connected to the upper end of the mounting base 1 through the fixing member 2, and the lower end of the mounting base 1 is coaxially arranged with the guide end.

[0042] Mounting base 1 is fixed to an external mounting surface (such as the ground), with its lower end serving as an anchoring end. Clamping member 3 has a connecting end and a guiding end, with the connecting end located at the bottom of clamping member 3 and detachably mechanically connected to the upper end of mounting base 1 via fixing member 2. The lower end of mounting base 1 and the guiding end of clamping member 3 are vertically aligned along the same central axis, forming a coaxial layout. Mounting base 1 provides a structural foundation fixing function, anchoring the entire belt clamp structure to the external mounting surface. Fixing member 2 provides a removable locking force, enabling rapid assembly and disassembly between clamping member 3 and mounting base 1. Clamping member 3 accommodates and constrains the belt through its internal structure, while its guiding end guides the belt's transmission direction. These three components work together to form the core functional unit for belt clamping and transmission.

[0043] After mounting base 1 is secured, clamping member 3 is aligned with the upper end of mounting base 1 via its connecting end and locked in place by fixing member 2. The belt is placed within the internal accommodation space of clamping member 3, where its structural restraint prevents it from slipping out. The guide end ensures smooth, coaxial transmission of the belt. To maintain or replace the belt, simply remove fixing member 2 to separate clamping member 3 from mounting base 1 and directly remove the belt for further operation without destructive disassembly.

[0044] In light of the background art, traditional belt fixing methods require strong clamping, which can cause irreversible deformation, making maintenance difficult and preventing belt replacement. This embodiment utilizes a fixing member 2 to achieve a removable connection between the clamping member 3 and the mounting base 1, replacing the irreversible clamping operation. For disassembly, simply release the fixing member 2 to separate the components and remove the belt. The coaxial design simplifies assembly and prevents misalignment. The internal containment structure of the clamping member 3, combined with its removable nature, allows for tool-free belt replacement or shortening, completely resolving the maintenance difficulties and lack of adjustability inherent in traditional solutions.

[0045] In a specific embodiment, Figure 3As shown, the upper end of the mounting base 1 has a protrusion 11, and the clamping member 3 has a first cavity 31 for accommodating the belt 6. Figure 2 As shown, the protrusion 11 cooperates with the first cavity 31 to squeeze the belt 6 .

[0046] In this embodiment, the mating mechanism between the protrusion 11 and the first cavity 31 within the clamping member 3 is defined. The first cavity 31 is used to accommodate and position the belt 6. The protrusion 11 and the first cavity 31 work together to generate mechanical pressure to compress the belt 6, thereby preventing the belt 6 from accidentally dislodging when secured. The core effect of this structure is that it avoids the permanent deformation and locking issues associated with traditional clamping methods. This compression mechanism is implemented through a detachable installation method, significantly reducing installation difficulty and improving operational convenience. Specifically, the belt 6 can be stably secured without applying high operating force during installation. The disassembly process is also simplified, allowing for direct removal and replacement when the belt 6 becomes fatigued or worn, thereby improving the system's maintainability and service life.

[0047] Furthermore, the existing technology also lacks a belt tension adjustment mechanism. Transmission failure caused by belt slack can only be addressed by replacing the entire system. This structural flaw has become a technical bottleneck that restricts the service life and user experience of linked door products. To address the existing lack of a belt tension adjustment mechanism, this embodiment indirectly achieves tension adjustment by combining the technical features of the protrusion 11 and the first cavity 31 to squeeze the belt 6. This, combined with the removable connection between the mounting base 1 and the clamping member 3 via the fixing member 2, allows for detachable mounting base 1. Specifically, when belt 6 slackens and causes transmission failure, the mounting base 1 can be separated from the clamping member 3 by simply removing the fixing member 2, allowing the belt 6 to be easily removed for shortening or replacement, and then reassembled. The extrusion design of the protrusion 11 and the first cavity 31 ensures that after re-attaching the belt 6, it automatically adapts to the new length and maintains tension, eliminating the need for a complete system replacement. This not only overcomes the adjustment bottleneck caused by irreversible clamping in the existing technology, but also significantly improves user experience and product lifespan, while avoiding the issues of limited operating tools or destructive disassembly.

[0048] In a specific embodiment, Figure 3 As shown, the upper end of the mounting base 1 includes a plurality of side panels 12, and the plurality of side panels 12 enclose a second cavity 13 with a notch; one of the side panels 12 has the protrusion 11 extending toward the second cavity 13; the plurality of side panels 12 include two oppositely arranged side panels 12, and the two oppositely arranged side panels 12 both have a first mounting hole 14 for mounting the fixing member 2.

[0049] The mounting base 1 includes a plurality of side panels 12, and the plurality of side panels 12 enclose a second cavity 13 with a notch. This arrangement provides space for accommodating the clamping member 3 through the second cavity 13 formed by the side panels 12. The notch design facilitates the insertion and assembly of the clamping member 3 along a specific direction, significantly reducing the difficulty of installation. The protrusion 11 extends from the side panel 12 and directly acts on the interior of the second cavity 13, so that when it cooperates with the first cavity 31, it can be precisely aligned with the extrusion position of the belt 6 to avoid installation deviation. In addition, the symmetrically distributed first mounting holes 14 provide a uniform force fulcrum for the fixing member 2, ensuring that the overall structure of the mounting base 1 is stable and non-deflected when the fixing member 2 is locked, thereby maintaining the continuous extrusion force of the protrusion 11 on the belt 6.

[0050] This embodiment utilizes a notched second cavity 13 to facilitate rapid positioning and insertion of the clamping member 3. Combined with the directional extension of the protrusion 11 on the side plate 12 and the symmetrically distributed first mounting holes 14, this creates a triple security mechanism: first, it ensures ease of installation (particularly suitable for use in confined spaces); second, it ensures directional accuracy when the protrusion 11 compresses the belt 6; and third, it ensures torsional stability after the fixing member 2 is locked. This allows the entire belt clamp structure to be quickly assembled and disassembled while effectively maintaining consistent tension on the belt 6, fundamentally addressing the problems of belt slippage and adjustment failure caused by misaligned installation or uneven stress in traditional solutions.

[0051] The fixing part 2 is used to fix the clamping part 3 and the mounting base 1. There are two fixing methods:

[0052] The first type, the fixing member 2 is a first fixing screw, such as Figure 1 and Figure 5 As shown, there are two of them, and the two first fixing screws respectively abut against the side of the clamping member 3 in the second cavity 13 through the first mounting holes 14. When the two first fixing screws are symmetrically screwed in from both sides of the mounting base 1, the screw heads pass through the first mounting holes 14 and directly press against the side of the clamping member 3, stably locking the clamping member 3 in the second cavity 13 through lateral pressure. This fixing method, combined with the symmetrical design of the first mounting holes 14, can evenly distribute the locking force, preventing the clamping member 3 from shifting or rotating in the second cavity 13, thereby maintaining the extrusion positioning of the boss 11 and the first cavity 31 on the belt 6; at the same time, during disassembly, the clamping member 3 can be separated by only loosening the first fixing screws, completely avoiding the destructive disassembly problem caused by the irreversible deformation of the traditional clamping structure, and significantly improving the efficiency of belt replacement.

[0053] The second type is that the fixing member 2 is a second fixing screw, such as Figure 2 and Figure 6As shown, the side wall of the first cavity 31 has a second mounting hole 32, and the second fixing screw passes through the first mounting hole 14 and the second mounting hole 32. The second fixing screw passes through the first mounting hole 14 symmetrically arranged on the mounting base 1 and the second mounting hole 32 on the side wall of the first cavity 31 of the clamping member 3 in sequence, forming a through-type mechanical connection. This connection method directly fastens the mounting base 1 and the clamping member 3 into an integral structure, so that the squeezing force of the protrusion 11 and the first cavity 31 on the belt 6 is transmitted through a rigid connection, avoiding relative displacement of the components; at the same time, the symmetrically distributed first mounting holes 14 and the second mounting holes 32 ensure that the tightening force is evenly distributed, preventing local stress concentration from causing structural deformation. Compared with the first lateral abutment method, this through-type connection greatly improves the structural integrity, effectively resists the periodic vibration of the belt 6 during operation, and maintains tension stability for a long time.

[0054] In a specific embodiment, the clamping member 3 has a first protrusion 33 extending outward, and the edge of the upper end notch of the mounting base 1 has a groove 15, and the first protrusion 33 cooperates with the groove 15 to achieve the connection between the clamping member 3 and the mounting base 1.

[0055] In this embodiment, the first protrusion 33 automatically pre-positions the clamping member 3 and the mounting base 1 as it slides along the groove 15, eliminating the need for manual adjustment of the extrusion position alignment between the protrusion and the first cavity 31, significantly reducing the difficulty of assembly in confined spaces. Furthermore, the engagement of the first protrusion 33 with the groove 15 forms a mechanical interlock, providing a temporary restraining force against belt tension when the fixing member 2 is not locked, preventing accidental assembly separation during operation. Its directional sliding trajectory forces a unique assembly direction, completely eliminating the risk of extrusion failure caused by misalignment between the protrusion 11 and the first cavity 31 due to skewed installation. Ultimately, this structure simplifies traditional multi-degree-of-freedom assembly into a single-step "directional insertion-engagement" action, significantly reducing installation time and ensuring that the extrusion force of the protrusion 11 on the belt 6 is evenly distributed after the fixing member 2 is locked. This addresses the technical shortcomings of the prior art, such as repeated disassembly of adjacent hardware and the inability to insert operating tools.

[0056] In some embodiments, as Figure 4 As shown, the mounting base 1 has a through hole 17 on the side plate for extending the protrusion 11, and the clamping member 3 has a second protrusion 34 on the surface corresponding to the side plate. The second protrusion 34 can be stuck in the through hole 17. Figure 4 、 Figure 9 as well as Figure 12 The cooperation between the second protrusion 34 and the through hole 17 makes the combination of the clamping member 3 and the mounting base 1 more compact and the installation more standardized, thus avoiding extrusion failure caused by misalignment between the protrusion 11 and the first cavity 31 due to installation deviation.

[0057] In a specific embodiment, Figure 9 As shown, the guide end includes a guide wheel 35 and a knurled shaft 36. The guide wheel 35 is sleeved on the columnar structure at the top of the clamping member 3, and the knurled shaft 36 is pressed into the columnar structure.

[0058] The guide pulley 35 is rotatably mounted on the outer circumference of the columnar structure through a hollow hole. The knurled shaft 36 is inserted into the inner hole of the columnar structure through an interference fit, creating a frictional lock between the patterned sidewalls of the knurled shaft 36 and the inner wall of the columnar structure. The guide pulley 35 functions to convert sliding friction between the belt 6 and the profile notch as it passes around its outer circumference, eliminating noise from the door leaf's movement. The knurled shaft 36 permanently fixes the columnar structure's shape through the radial expansion force generated by the press fit, preventing axial movement or radial deflection of the guide pulley 35.

[0059] In this embodiment, the rolling friction mechanism of the guide pulley 35 significantly reduces the transmission resistance of the belt 6. The press-fit structure of the knurled shaft 36, by enhancing the rigidity of the columnar structure, ensures that the guide pulley 35 maintains parallelism with the profile slots despite lateral tension from the belt 6. This systematically addresses the existing problem of belt deviation causing transmission failure. The rolling path of the guide pulley 35 constrains the lateral displacement of the belt 6, while the deformation resistance of the knurled shaft 36 ensures that this constraint direction does not deviate, ensuring silent and smooth operation of the door leaf.

[0060] In a specific embodiment, Figure 3 and Figure 4 As shown, the lower end of the mounting base 1 has a downwardly extending mating end 16 , and an anti-rotation screw 4 is provided in the mating end 16 .

[0061] The mating end 16 serves as an interface structure for the mounting base 1, and its axial extension direction is perpendicular to the transmission plane of the belt 6; the anti-rotation screw 4 penetrates the side wall of the mating end 16 and presses against the external mounting surface. The core technical effect produced by this structure is that when the belt 6 generates a torsional torque during operation, the anti-rotation screw 4 forms a point-contact friction constraint with the surface of the mounting base 1, preventing the mounting base 1 from rotating around its axis. This solves the problem of base displacement caused by vibration or lateral belt tension in the prior art. For example, at the moment of door start and stop, if the anti-rotation screw 4 is not provided, the rotation of the mounting base 1 will cause the protrusion 11 to deviate from the preset extrusion position of the first cavity 31, causing the belt 6 to fall out; the mechanical locking mechanism formed by the anti-rotation screw 4 in this embodiment ensures that the protrusion 11 and the first cavity 31 always remain aligned, so that the belt tension is stable for a long time, and systematically avoids the problem of doubled maintenance costs caused by frequent adjustments to the base in the prior art.

[0062] In a specific embodiment, the mating end is sleeved with an expansion tube 5 which is fixed on the ground; the mating end 16 of the mounting base 1 is inserted into the expansion tube 5 .

[0063] First, the expansion tube 5 acts as a pre-buried anchor in the ground, forming a high-strength bond with the ground through its expansion mechanism, replacing the traditional multi-part assembly base structure; secondly, the mating end 16 is inserted axially into the expansion tube to achieve rapid positioning and installation of the mounting base 1, simplifying the installation steps to a single plug-in action. After the expansion tube 5 is pre-buried, it only needs to be inserted into the mating end 16 to complete the positioning, without the need to operate additional fasteners in a narrow space, significantly improving construction efficiency. At the same time, the plug-in structure of the mating end 16 and the expansion tube provides an installation basis for the anti-rotation screw 4. The anti-rotation screw 4 can penetrate the mating end 16 and press against the inner wall of the expansion tube 5 to form an anti-torsion constraint, thereby maintaining the stability of the extrusion position of the belt 6 by the protrusion 11 and the first cavity 31, and preventing the belt from falling out due to base displacement.

[0064] In a specific embodiment, the mounting base 1, the fixing member 2 and the clamping member 3 are coaxially arranged. The central axes of the mounting base 1, the fixing member 2 and the clamping member 3 coincide with the same vertical line. The core technical effect of this feature is: first, the mounting base 1, the clamping member 3 and the fixing member 2 running through them are distributed along a single axis, so that the assembly process only requires applying operating force vertically downward, avoiding the problem of the tool being unable to align due to the angle deviation of the parts in the traditional solution, directly solving the defect of "difficult installation" in the existing technology, and is particularly suitable for scenes with limited operating space such as the bottom of the door frame; secondly, the coaxial structure ensures that the protrusion 11 of the mounting base 1 and the first cavity 31 of the clamping member 3 are always aligned, and when the belt 6 is squeezed, the lateral shear force it bears is close to zero, which greatly reduces the local wear of the belt 6 and maintains the stability of the tension of the belt 6 for a long time, solving the technical bottleneck of "the belt needs to be replaced as a whole due to fatigue during its life" in the existing technology.

[0065] The assembly process of the belt clip structure provided in this embodiment is as follows:

[0066] First, screw the expansion tube 5 into the pre-set hole in the ground to anchor it; vertically insert the mating end 16 at the bottom of the mounting base 1 into the expansion tube 5, and tighten the anti-rotation screw 4 so that it abuts the inner wall of the expansion tube 5 to limit rotation. Next, place the guide wheel 35 on the columnar structure at the top of the clamp 3, and then press the knurled shaft 36 into the inner hole of the columnar structure to fix the guide wheel 35. Then, place the belt 6 into the first cavity 31 of the clamp 3; through the first protrusion 33 of the clamp 3 and the groove 15 on the edge of the notch of the mounting base 1, insert the clamp 3 obliquely into the second cavity 13 of the mounting base 1 to achieve preliminary locking and limiting. Finally, two fixing methods are selected according to the structural requirements: Method 1: Use two first fixing screws as the fixing member 2, respectively pass through the first mounting hole 14 on the opposite side plate 12 of the mounting base 1, and press against the side of the clamp 3; Method 2: Use a second fixing screw as the fixing member 2, pass through the first mounting hole 14 and the second mounting hole 32 on the side wall of the first cavity 31 in sequence to lock it. During the entire installation process, ensure that the mounting base 1, the clamping member 3 and the fixing member 2 are coaxially aligned.

[0067] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0068] The above are merely preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
