Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, specifically to a glass curtain wall locking device. Background Technology

[0002] Glass curtain walls typically consist of glass panels, supporting frames, and other structural components. The locking mechanism (also known as a clamping block, latch, locking plate, or clamping plate) is a core component in the curtain wall system used for mechanically securing the glass panels. It is usually made of metal (such as aluminum alloy or stainless steel) and is fixed to the supporting frame of the curtain wall using bolts or screws, firmly "locking" the glass in its preset position.

[0003] Existing glass curtain wall locking devices still have some shortcomings. They typically embed the glass panel into the slot of the main frame and then use a locking mechanism to firmly fix the glass. However, the main frame is affected by temperature changes, which can cause the main frame to expand due to heat and squeeze the glass. If the squeezing force is too great, it can cause the glass to break. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a glass curtain wall locking device, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a main frame, with fixed plates fixedly connected around its perimeter. Glass is provided on the inner side of the main frame, and an elastic strip is provided on the inner side of the main frame. The elastic strip is used to buffer the force exerted by the main frame due to thermal expansion and compression of the glass panel. A spring pin mechanism with its axis perpendicular to the elastic strip is provided inside the fixed plates. A pressure plate is provided at one end of the spring pin mechanism. The elastic strip has an L-shaped cross-section. Two sides of the elastic strip parallel to the axis of the spring pin mechanism contact the glass and the main frame, respectively. Two sides of the elastic strip perpendicular to the axis of the spring pin mechanism contact the glass and the pressure plate, respectively. The spring pin mechanism includes a spring and a pressure column, which provide a horizontal axial elastic force to the pressure plate to press against the elastic strip.

[0008] Optionally, the fixing plate is provided with a screw hole, and a screw rod is threadedly connected to the inner surface of the screw hole. A sleeve is fixedly connected to one end of the screw rod, and a ring is rotatably connected to one end of the sleeve. A limit plate is provided on the surface of the pressure column. The two ends of the spring are fixedly connected to the limit plate and the ring, respectively. By rotating the screw rod, the ring is driven to compress the spring. The elastic force of the spring can be adjusted by limiting the screw rod through the screw hole, so as to avoid the pressure plate being too tight or too loose.

[0009] Optionally, a bearing is fixedly connected to the inner surface of the ring, and the inner surface of the bearing is fixedly connected to the sleeve. The bearing prevents the spring from rotating with the sleeve.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0016] Please see Figures 1 to 3The present invention provides a technical solution including a main frame 4, with fixing plates 5 fixedly connected around the main frame 4. The fixing plates 5 are fixed to the main frame 4 around the main frame 4 by bolts and nuts. A slot 10 is provided on the inner side of the main frame 4. The slot 10 has an L-shaped cross-section and a glass 1 is provided on the inner side of the slot 10. An L-shaped elastic strip 3 is provided between the main frame 4 and the glass. The elastic strip 3 is made of rubber material. The elastic strip 3 is provided to facilitate replacement when it fails. The elastic strip 3 is located between the main frame 4 and the glass 1 and is used to buffer the heat of the main frame 4. The force that expands and compresses the glass 1 is provided by a spring pin mechanism with its axis perpendicular to the elastic strip 3 inside the fixed plate 5. A pressure plate 9 is provided at one end of the spring pin mechanism. The two sides of the elastic strip 3, which is parallel to the axis of the spring pin mechanism, are in contact with the glass 1 and the main frame 4, respectively. The two sides of the elastic strip 3, which is perpendicular to the axis of the spring pin mechanism, are in contact with the glass 1 and the pressure plate 9, respectively. The spring pin mechanism includes a spring 8 and a pressure column 14. One end of the pressure column 14 extends to the outside of the fixed plate 5 and is fixedly connected to the pressure plate 9. The spring 8 is sleeved on the pressure column 14. The spring 8 and the pressure column 14 provide the pressure plate 9 with a horizontal axial elastic force that presses against the elastic strip 3.

[0017] Specifically, when the main frame 4 expands due to heat, the deformation of the main frame 4 will compress the elastic strip 3. Due to the elasticity of the elastic strip 3, the compressive force of the main frame 4 on the glass 1 can be buffered. Through the cooperation of the fixing plate 5 and the pressure plate 9, the glass 1 is firmly fixed to prevent the glass 1 from shaking. The elasticity of the spring 8 can further buffer the compressive force of the main frame 4 on the glass 1.

[0018] Please see Figures 1 to 3 The fixed plate 5 has a raised groove 12, and a screw hole 6 is provided on one side of the inner surface of the raised groove 12. A screw rod 2 is threadedly connected to the inner surface of the screw hole 6. The screw rod 2 has a T-shaped cross-section and one end of the screw rod 2 extends to the outside of the fixed plate 5 for easy rotation by the operator. A sleeve 7 is fixedly connected to one end of the screw rod 2, and a ring 13 is rotatably connected to one end of the sleeve 7. A limit plate 11 is provided on the surface of the pressure column 14. The limit plate 11 is slidably connected to the raised groove 12. The raised groove 12 limits the limit plate 11 to prevent it from sliding out of the fixed plate 5. The two ends of the spring 8 are fixedly connected to the limit plate 11 and the ring 13 respectively. By rotating the screw rod 2, the ring 13 is driven to compress the spring 8. The screw rod 2 is limited by the screw hole 6 to ensure that the pressure plate 9 presses against the elastic strip 3.

[0019] Please refer to Figure 1 to Figure 3 A bearing is fixedly connected to the inner surface of the ring 13. The inner surface of the bearing is fixedly connected to the sleeve 7. The bearing prevents the spring 8 from rotating with the sleeve 7.

[0020] Please refer to Figure 1 to Figure 3The fixing plate 5 extends along the joint of the glass 1, and spring pin mechanisms are symmetrically arranged on both sides of it to abut against the elastic strips 3 of the two adjacent glass pieces 1, so as to ensure that the two adjacent glass pieces 1 can be fixed.

[0021] In use, the glass 1 is embedded into the slot 10 of the main frame 4, and the elastic strip 3 is embedded between the main frame 4 and the glass 1. When the main frame 4 is heated and expands, the deformation of the main frame 4 will squeeze the elastic strip 3. Due to the elasticity of the elastic strip 3, the squeezing force of the main frame 4 on the glass 1 can be buffered, and the excessive squeezing force of the main frame 4 will prevent the glass 1 from breaking. The fixing plate 5 is fixed around the main frame 4 by bolts and nuts, so that the pressure plate 9 is in contact with the elastic strip 3, and the glass 1 is fixed firmly. When the main frame 4 is heated and expands, the elasticity of the spring 8 can buffer the squeezing force of the main frame 4 due to the thermal expansion. By rotating the screw 2, the sleeve 7 is driven to rotate. Since the sleeve 7 is connected to the ring 13 through the bearing, the ring 13 can squeeze the spring 8. The screw hole 6 limits the screw 2, and the elastic force of the spring 8 can be adjusted. The clamping force of the pressure plate 9 on the glass 1 can be adjusted, so as to avoid the pressure plate 9 pressing the glass 1 too tightly or too loosely.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
