Description

Technical Field

[0001] This utility model relates to glass clamping components, and more particularly to a glass clamping device. Background Technology

[0002] In modern building curtain walls, interior partitions, door and window systems, and furniture manufacturing, clamping fixture systems are widely used for the installation and fixing of glass, stone, metal sheets, and other sheet materials. These systems typically consist of a fixed part and a movable clamping part, using a locking mechanism to generate clamping force and securely hold the sheet material within.

[0003] The most common clamping systems on the market currently have the following drawbacks: First, the adjustment flexibility is poor. Many existing clamps have pre-set positions for their movable clamping blocks or can only be fixed at a limited number of points, making it impossible to achieve stepless adjustment along the length of the profile. This is extremely inconvenient when dealing with non-standard sized plates or when precise adjustment of the clamping position is required, thus limiting its application range.

[0004] Secondly, the clamping effect is poor, and the material is easily damaged. Traditional clamping methods are mostly rigid, straight-face clamping, with the clamping force concentrated on a line or point rather than distributed across a surface. This can easily lead to excessive local stress on the clamped material (especially glass), posing a risk of crushing or developing micro-cracks. At the same time, rigid clamping has poor adaptability to the thickness tolerance of the material; it may either not clamp tightly enough or be too tight, causing damage.

[0005] Third, the locking process may introduce instability. In some designs, the locking bolt directly pushes the movable clamping block, which may generate lateral force, causing the movable clamping block to shift, tilt, or even jam, resulting in non-parallel clamping surfaces, further exacerbating stress concentration and installation inconvenience.

[0006] Fourth, insufficient aesthetics and sealing. The exposed metal structures and mechanical parts of most functional fixtures affect the overall appearance. In addition, there are often assembly gaps between the fixtures and the panels, and the lack of effective sealing measures may lead to the infiltration of rainwater and dust, affecting the building's energy efficiency and indoor environment.

[0007] Therefore, the industry urgently needs a new type of glass clamping device that can flexibly adjust and reliably lock the movable clamping parts at any position, while providing uniform, stable clamping force that does not damage the glass, and also has good aesthetics and sealing performance. Utility Model Content

[0008] The purpose of this invention is to provide a glass clamping device that enables flexible adjustment and reliable locking of the movable clamping element at any position, while providing uniform, stable clamping force that does not damage the glass sheet, and also has good aesthetics and sealing performance.

[0009] The technical solution to achieve the purpose of this utility model is as follows: This utility model includes: The main profile has a first clamping surface and a bottom support surface integrally connected in an L-shape along the extension direction; At least one movable clamping element is slidably mounted on the bottom support surface; A locking mechanism is used to drive the movable clamping member to move toward the first clamping surface to clamp the glass; The first clamping surface is provided with a first sliding groove arranged along its extending direction; The bottom support surface is provided with a second sliding groove arranged along its extending direction; The movable clamping member includes a sliding portion that slidably engages with a second slide groove, and the engagement is configured to allow the movable clamping member to rotate about the sliding portion within the second slide groove; The locking mechanism includes a threaded sleeve and a bolt; The threaded sleeve is slidably disposed in the first groove, and one end of it is provided with a limiting part. The limiting part is configured to prevent the threaded sleeve from coming out of the first groove but allow it to slide along the first groove. The movable clamping component is provided with a locking connection hole; The bolt passes through the locking connection hole and engages with the threaded sleeve. When the bolt is tightened, it can drive the movable clamping member to rotate around its sliding part and press against the first clamping surface.

[0010] Furthermore, the first clamping surface is also provided with a first clamping part, and the first sliding groove is located below the first clamping part; the movable clamping member also includes a second clamping part disposed opposite to the first clamping part; an anti-slip layer is embedded on the first clamping part and / or the second clamping part.

[0011] Furthermore, the aforementioned anti-slip layer is made of rubber.

[0012] Furthermore, the first slide groove has an opening groove on its end face facing the movable clamping member, and one end of the threaded sleeve extends out of the first slide groove through the opening groove. The extended end is provided with an internal threaded hole that mates with a bolt.

[0013] Furthermore, the aforementioned limiting part is a head that is radially expanded at one end of the threaded sleeve.

[0014] Furthermore, the cooperation between the aforementioned movable clamping member and the second slide groove satisfies one of the following conditions: the cross-section of the second slide groove is an arc-shaped groove, and the sliding part is a sphere or cylinder adapted to the arc-shaped groove; or the sliding part is rotatably connected to the second clamping part of the movable clamping member through a rotating shaft, and the rotating shaft is slidably disposed in the second slide groove.

[0015] Furthermore, the upper and / or lower ends of the main profile and the upper and / or lower ends of the movable clamping member are provided with slots for assembling the cover plate.

[0016] It also includes a cover plate, the edge of which is provided with a snap-fit ​​structure that mates with a slot. The cover plate is installed on the main body profile and / or movable clamping member by means of the snap-fit ​​structure and the engagement of the slot, so as to cover its exterior.

[0017] Furthermore, the cover plate is provided with an installation part for installing a sealing strip; the sealing strip is used to fill the gap between the cover plate and the clamped glass.

[0018] Furthermore, the aforementioned mounting part is a claw extending from the cover plate toward the side of the clamped glass, and the sealing strip is provided with a groove that is interference-fitted with the claw.

[0019] This utility model has the following positive effects: (1) This utility model realizes stepless and continuous position adjustment of the movable clamping part on the main profile, which has a wide range of applications and flexible installation. Through the cooperation of the sliding part sliding in the second slide groove and the threaded sleeve sliding in the first slide groove, the movable clamping part is freely positioned in the two-dimensional plane. At the same time, the unique clamping mechanism that rotates around the sliding part makes the movable clamping part generate a downward component force when locking, forming an adaptive clamping, which is especially suitable for glass with a certain thickness tolerance, ensuring the stability and reliability of clamping, while avoiding the jamming problem that may be caused by rigid direct push.

[0020] (2) This utility model clearly sets up a first clamping part and a second clamping part, which together with the L-shaped main body form a stable three-point clamping system with reasonable force distribution and more stable clamping. At the same time, an anti-slip layer is set up, which has the beneficial effects of increasing friction and preventing the clamped glass from sliding; buffering hard contact and effectively preventing the glass edge from being crushed due to point stress concentration; and adapting to slightly uneven surfaces to ensure uniform distribution of clamping force.

[0021] (3) This utility model specifically defines the anti-slip layer as rubber material, which provides excellent elasticity, wear resistance and high coefficient of friction, and is the best economical and efficient choice to achieve anti-slip and buffer protection functions.

[0022] (4) The open slot design in this utility model allows the threaded hole of the threaded sleeve to be exposed, making it easy for the bolt to be screwed in smoothly from the side, and the assembly process is intuitive and simple. This structure restricts the sliding trajectory of the threaded sleeve within the first groove, ensuring that the locking force is always transmitted in the predetermined direction, thereby improving the rigidity and stability of the system.

[0023] (5) The limiting part of this utility model adopts the design of an enlarged head because this design is a standard part or an easy-to-process structure, which realizes the anti-dislodgement function of the threaded sleeve, while ensuring its smooth sliding, low manufacturing cost and high reliability.

[0024] (6) This utility model clearly provides two preferred mechanical structures for realizing the "sliding + rotating" function. Among them, the arc groove and the sphere / cylinder schemes are compact, flexible in rotation, and easy to process and assemble. The shaft connection scheme separates the rotation function from the sliding function, making the movement more precise and stable, and with stronger load-bearing capacity. These two schemes provide specific and reliable implementation paths for this core function, enhancing the feasibility of the invention.

[0025] (7) By setting up standardized slots, this utility model provides a modular, tool-free quick assembly interface for the installation of the cover plate, which greatly improves the aesthetics of the product and the convenience of installation and maintenance.

[0026] (8) The cover plate of this utility model can be quickly installed and removed without the use of additional tools and fasteners through the cooperation of buckle and slot, which facilitates the inspection and maintenance of the internal clamping system, and at the same time makes the product appearance more neat and high-end.

[0027] (9) By adding a sealing strip, this utility model effectively fills the assembly gap between the cover plate and the glass. Its beneficial effects are: windproof, waterproof and dustproof, improving the sealing performance and energy-saving effect of the building; shock absorption and sound insulation, reducing the noise caused by vibration; further improving the overall quality and durability of the product.

[0028] (10) The installation method of the sealing strip in this utility model makes the sealing strip more secure and convenient to fix. The claw type makes it easy to replace. Attached Figure Description

Of course, it can also be set as a sphere. In this embodiment, a cylindrical design is adopted.

[0037] The upper and lower ends of the main profile 1, and the upper and lower ends of the movable clamping member 2, are provided with slots 7 for assembling the cover plate 6. The edge of the cover plate 6 is provided with a snap-fit ​​structure 61 that mates with the slot 7.
