DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-8 The present invention provides a technical solution: an installation structure for curtain wall gap decorative strips that can be easily replaced, including a decorative strip plate 1, a rubber cover 2, a movable frame 9 and a keel frame 17.

[0037] A decorative light strip is installed in the plate cavity of the decorative strip plate 1 in the curtain wall gap decorative strip, which is a light decorative strip. The keel frame 17 in the curtain wall gap decorative strip is fixedly placed in the gap between two adjacent curtain walls and is used to place and bear the decorative strip plate 1. The sleeve block 4 and the movable frame 9 are symmetrically arranged about the horizontal center axis of the decorative strip plate 1. The movable frame 9, the locking claw 15 and the locking groove 18 constitute a set of locking structures for the curtain wall gap decorative strip, that is, the locking structures are symmetrically arranged about the horizontal center axis of the decorative strip plate 1, and the two sets of locking structures are used to fix the curtain wall gap decorative strip.

[0038] Before installing the curtain wall gap decorative strip, the movable frame 9 needs to be adjusted to the initial standby state. Figure 2 、 Figure 3 and Figure 6 As shown, the middle part of the rear panel of the decorative strip 1 protrudes outward and is provided with a seat body of an integrated structure, wherein the left and right side walls of the seat body are provided with arc-shaped rail grooves, and the cross section of the movable frame 9 is a "U"-shaped structure, and the middle part of the left longitudinal frame and the middle part of the right longitudinal frame are bent to provide ball grooves, and the upper and lower ends of the ball grooves are fixedly connected with end covers for blocking by bolts. After the movable frame 9 is placed, it is movably clamped on the seat body of the decorative strip 1, wherein the ball groove and the decorative strip are connected. 1 is adapted to be arranged in a corresponding state, and because the ball 10 is movably stuck in the connection between the ball groove in the movable frame 9 and the arcuate rail groove in the decorative strip plate 1 after being placed, it is arranged at equal intervals in the ball groove in the movable frame 9 and is arranged in a sliding state, pushing the movable frame 9 so that the movable frame 9 slides on the seat portion in the decorative strip plate 1 with the assistance of the ball 10, and the movable frame 9 is slid to the ready state, that is, when the decorative strip plate 1 is placed, the locking claw 15 is arranged corresponding to the locking groove 18;

[0039] Since the left and right sides of the horizontal frame body in the movable frame 9 are bent and provided with a paddle portion of an integrated structure, wherein the paddle portion is arranged in a vertical state, and the paddle portion movably passes through the slide groove of the columnar groove cavity in the decorative strip plate 1 and is inserted into the cavity, and since a second spring 11 is installed at the connection between the movable frame 9 and the base portion in the decorative strip plate 1, the second spring 11 is symmetrically arranged about the vertical central axis of the movable frame 9. After being installed, it is movably inserted into the columnar groove cavity in the decorative strip plate 1, and one end thereof abuts against the wall of the columnar groove cavity in the decorative strip plate 1, and the other end abuts against the paddle portion in the movable frame 9. During the sliding process of the movable frame 9, the second spring 11 is squeezed and elastically deformed.

[0040] Since the longitudinal cross-section of the second lock column 13 is in the shape of a "convex" character, the upper and lower side walls of the wide portion thereof are both protrudingly provided with stopper portions of an integrated structure. After the second lock column 13 is installed, the wide portion thereof is movably inserted into the hole-shaped groove cavity of the base portion of the decorative strip plate 1, and the narrow portion thereof extends to the outside. Moreover, the stopper portions thereof are movably clamped on the wall of the hole-shaped groove cavity of the decorative strip plate 1, and are positioned in the hole-shaped groove cavity of the base portion of the decorative strip plate 1 in an active state.

[0041] Since the positioning groove 12 is in a through-state and is opened in the middle of the horizontal frame body of the movable frame 9, it is composed of a combination of a circular groove and a strip groove, and is arranged in a corresponding state with the second lock column 13. In addition, since a third spring 14 is installed at the connection between the second lock column 13 and the seat body portion in the decorative strip plate 1, the third spring 14 is movably inserted into the groove cavity of the wide part of the second lock column 13 after being placed, one end of the third spring 14 is against the groove wall of the second lock column 13, and the other end is against the wall of the hole-shaped groove cavity in the decorative strip plate 1. After the movable frame 9 slides, the third spring 14 restores its elastic deformation, so that the second lock column 13 slides in the hole-shaped groove cavity of the seat body portion in the decorative strip plate 1, and the wide part of the second lock column 13 is engaged with the circular groove path in the positioning groove 12 to lock the movable frame 9 adjusted to the ready state;

[0042] When installing the curtain wall gap decorative strip, Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, the keel frame 17 is divided into two parts, the plate frame part and the frame part. The front frame wall of the frame part in the keel frame 17 is recessed inwardly and provided with a waterproof groove in the shape of a "U". The rear plate surface of the decorative strip plate 1 is provided with a circular baffle 3 of an integrated structure. The circular baffle 3 is arranged in a vertical state after being placed. A sealing gasket is clamped and glued on the outer wall of the decorative strip plate 1. The decorative strip plate 1 is clamped and placed on the keel frame 17 so that the circular baffle 3 is inserted and clamped in the waterproof groove in the keel frame 17. Since the rubber cover 2 is clamped and glued to the plate wall of the decorative strip plate 1, it is arranged in a trumpet-shaped structure. After the decorative strip plate 1 is placed, the rubber cover 2 is overlapped on the curtain wall.

[0043] Since a locking groove 18 and an unlocking groove 19 are sequentially provided on the inner frame wall of the frame portion of the keel frame 17 from front to back, the unlocking groove 19 and the locking groove 18 are symmetrically arranged about the vertical central axis of the keel frame 17, and the left longitudinal frame end portion and the right longitudinal frame end portion of the movable frame 9 are movably installed with a locking claw 15, and the left and right locking claws 15 in the movable frame 9 are combined to form an "eight"-shaped structure, and the claw end of the locking claw 15 is provided with a plane side wall, wherein the plane side wall is arranged in a forward state, and after it is placed, it is arranged in an inclined state on the longitudinal frame of the movable frame 9, and a rotating structure is formed at the longitudinal frame end of the movable frame 9 with the assistance of a shaft bolt, and since a spring 16 is installed at the connection between the locking claw 15 and the longitudinal frame of the movable frame 9, the spring 16 After placement, it is arranged in an inclined state with the locking claw 15, one end of which is fixedly riveted to the longitudinal frame body in the movable frame 9, and the other end thereof abuts against the groove wall of the claw body in the locking claw 15. During the placement of the decorative strip panel 1, the circular baffle 3 slides in the waterproof groove in the keel frame 17, and the locking claw 15 is blocked by the frame portion in the keel frame 17 and flipped on the longitudinal frame body in the movable frame 9, so that the spring piece 16 is squeezed and elastically deformed. After the decorative strip panel 1 is placed, the claw end of the locking claw 15 corresponds to the locking groove 18, and the elastic deformation of the spring piece 16 is used to reset, so that the claw end of the locking claw 15 is engaged with the locking groove 18, and the flat side wall of the claw end of the locking claw 15 abuts against the groove wall in the locking groove 18, completing the locking of the decorative strip panel 1 after placement;

[0044] After the first lock column 7 is installed, its front section is connected to the sleeve block 4 in a movable and penetrating manner, and its rear section is movably inserted through the middle strip groove of the decorative strip plate 1 and extends to the outside. When the first lock column 7 is in the locked state, the front end side wall of the first lock column 7 is arranged in a state of abutment with the wall of the middle strip groove of the decorative strip plate 1, and the rear end side wall of the first lock column 7 is also arranged in a state of abutment with the plate frame portion of the keel frame 17. The pressure support of the first lock column 7 prevents the decorative strip plate 1 from excessive sliding, thereby ensuring the locking effect of the decorative strip plate 1;

[0045] When dismantling the curtain wall gap decorative strip, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8As shown, friction columns 6 are clamped and glued on the left and right side walls of the sleeve block 4, and the friction columns 6 are arranged in a cylindrical structure. After the sleeve block 4 is placed, it is movable and clamped in the square strip groove cavity of the seat body of the decorative strip plate 1, so that the curved side wall of the friction column 6 and the wall of the square strip groove cavity in the decorative strip plate 1 are fitted together. Since the magnetic ring 5 is sleeved and fixed on the front end of the sleeve block 4, it is arranged in an integrated structural state. The magnetic ring 5 is attracted by the external magnet, and the external magnet drives the magnetic ring 5 to move simultaneously. The first locking post 7 is movably inserted into the through groove of the sleeve 4, and an auxiliary groove adapted to the first locking post 7 is extended forward on the groove wall at one end of the square groove of the decorative strip plate 1. After the sleeve 4 slides, the first locking post 7 corresponds to the auxiliary groove in the decorative strip plate 1, so that the first locking post 7 is set in an unlocked state, and the positioning of the sleeve 4 after movement is ensured by the damping effect of the friction post 6.

[0046] When the locking cam 11 is in the closed position, the locking cam 11 is in the closed position, and the locking cam 11 is in the closed position, so that the locking cam 11 is in the closed position, and the locking cam 11 is in the closed position, so that the locking cam 11 is in the closed position, and the locking cam 11 is in the closed position, so that the locking cam 11 is in the closed position, and the locking cam 11 is in the closed position, so that the locking cam 11 is in the closed position, and the locking cam 11 is in the closed position, so that the locking cam 11 is in the closed position,

[0047] Since the vertical center axis of the circular groove in the positioning groove 12 coincides with the vertical center axis of one of the strip grooves, and the diameter of the circular groove in the positioning groove 12 is larger than the width of one of the strip grooves, when the decorative strip plate 1 slides further, the locking claw 15 loses contact with the locking groove 18 and engages into the longitudinal groove of the unlocking groove 19, so that the end of the narrow part of the second lock column 13 contacts and is squeezed by the plate frame part of the keel frame 17, and the wide part of the second lock column 13 loses the engagement connection with the circular groove in the positioning groove 12, thereby releasing the lock of the movable frame 9. The elastic deformation of the second spring 11 is reset, and the movable frame 9 slides on the seat body of the decorative strip panel 1, so that the narrow part of the second lock column 13 slides along the strip groove of the positioning groove 12, and the claw end of the locking claw 15 slides in the longitudinal groove of the unlocking groove 19 to the transverse groove of the unlocking groove 19. Since the width of the claw end of the locking claw 15 is smaller than the width of the transverse groove of the unlocking groove 19, and the transverse groove of the unlocking groove 19 is set in an open state, the disassembly of the decorative strip panel 1 is completed through the opening of the transverse groove of the unlocking groove 19.

[0048] Summary of working principle: When installing the curtain wall gap decorative strip, the decorative strip plate 1 is clamped and placed on the keel frame 17, and the decorative strip plate 1 is pressed to make the circular blocking frame 3 engage in the waterproof groove in the keel frame 17, and locked by the engagement between the locking claw 15 and the locking groove 18. When removing the curtain wall gap decorative strip, adjust the first lock column 7 to the unlocked state, continue to press the decorative strip plate 1, so that the middle wide part of the second lock column 13 loses engagement with the circular groove in the positioning groove 12, and the elastic deformation of the second spring 11 is used to reset, so that the movable frame 9 drives the locking claw 15 to slide, and is unlocked with the help of the unlocking groove 19;
