In the figure: 1. the double-open glass door comprises a double-open glass door body, 2 vertical handrail tubes, 3 supporting beams, 4 horizontal rods, 5 sleeves, 6 chains, 7 reinforcing rods, 8 sliding grooves, 9 sliding blocks and a horizontal rod.
Detailed Description
As shown in figure 1, the embodiment of the utility model provides a safety lock for a double-opening glass door, which mainly comprises a horizontal rod 4 and two sleeves 5 fixed on the horizontal rod, wherein the axes of the two sleeves 5 are perpendicular to the axis of the horizontal rod 4, the two sleeves are arranged on the horizontal rod 4 at intervals, and the centers of the horizontal rods are taken as symmetrical points and are arranged on two sides of the symmetrical points at intervals.
Further, the bottom of horizon bar 4 is equipped with a chain 6, the right-hand member at horizon bar 4 is fixed to 6 length direction's of this chain one end, other end detachably fixes the left end at the horizontal steel, can be with two sleeve 5 suits on this safety lock on two vertical handrail pipes 2 on the present two glass door that open, then the bottom of bracing beam 3 on the handrail pipe is walked around to the one end of the chain 6 of bottom, fix other end detachably on the horizon bar, the closing of two glass door 1 has been realized, it is fixed through a chain to compare two vertical handrail pipes 2 on present two glass door 1 that open, the safety lock that this embodiment provided does not need the key, easy dismounting.
In particular, the horizontal rod 4 in this embodiment may be a solid body, which may increase the overall strength of the safety lock.
Meanwhile, the sleeve 5 in the embodiment is directly welded and fixed on the outer wall surface of the horizontal rod 4, so that the overall strength can be increased.
Certainly, in order to reduce the weight of the safety lock, the horizontal rod 4 may also be a tubular body, the tubular body may be a galvanized Q235 tubular body, may also be an iron tube, and may also be made of stainless steel, when the horizontal rod is a tubular body, a reinforcing rod 7 may be sleeved in the horizontal rod 4, as shown in fig. 2, the reinforcing rod 7 may be directly plugged in the horizontal rod, for example, the reinforcing rod adopts a rubber rod, and when the horizontal rod is a circular steel, the rubber rod is sleeved in the circular steel, and meanwhile, corresponding stoppers are to be provided at both ends of the circular steel to limit the reinforcing rod 7 from sliding out.
However, if the horizontal rod 4 is a circular steel and the reinforcing rod 7 is a rubber rod, the rubber rod needs to be inserted into the circular steel in advance, and then the sleeve 5 and the fixing ring 41 are welded, so that the problem that the rubber rod cannot be inserted into the circular steel due to welding deformation after the sleeve and the fixing ring are welded is avoided.
Preferably, the sleeve in this embodiment is also preferably round steel.
In order to fix the chain, as shown in fig. 2 to 3, in this embodiment, the outer wall surfaces of the two ends of the horizontal rod 4 in the length direction are respectively welded with a fixing ring 41, wherein the right end of the chain is directly sleeved on the fixing ring at the right end of the horizontal rod, the left end of the chain is connected with a key buckle, the key buckle can be opened in a rotating manner, when the two sleeves on the safety lock in this embodiment are sleeved on the door handle of the double-opening glass door, the key buckle of the chain can be buckled on the fixing ring on the horizontal rod, and the operation is simple.
It should be noted that the length of the chain 6 in this embodiment is greater than the distance between the two sleeves 5, and preferably less than the length of the support rod 4, because when the two sleeves are fitted over the two vertical handles on the double-opening glass door, the chain is passed around the bottom of the two support beams 3 and is snapped over the fixing ring by the key at its end, but the length of the chain is not too long.
Considering that the distance between the two vertical handles on different double-opening glass doors 1 is different, in order to adapt the safety lock in the present embodiment to double-opening glass doors with different distances, as shown in fig. 4, a sliding groove 8 can be welded and fixed on the outer wall surface of the horizontal rod in the present embodiment in the length direction, and a sliding block 9 which can move in the sliding groove is welded on the sleeve, so that the distance between the two sleeves 5 can be adjusted according to the distance between the two vertical handrail tubes 2 on the double-opening glass door 1.
Both ends of the sliding groove in the embodiment need to be closed, so that the two sleeves can not slide out of the sliding groove.
Of course, in other embodiments, a horizontal sliding block may be welded to the outer wall surface of the horizontal rod, and a sliding groove is also formed in the sleeve, and the sliding block may be inserted into the sliding groove and may slide, so that the distance between the two sleeves may also be adjusted.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
