[0023] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0025] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0026] See Figure 1-9 As shown, the present application discloses a soft rope high-reliability safety lock, comprising a lock body 1, a slider 2, a spring sheet 3, a wire rope assembly 5 and a lock seat 6; the lock body 1 and the lock seat 6 are respectively fixed on the window frame and the window sash by self-tapping screws; a receiving groove 11 is provided on the lock body 1, and the slider 2 is slidably arranged above the receiving groove 11, and can only slide out along one end of the lock body 1 and be separated from the lock body 1; specifically, see Figure 4-8 As shown, the outer contour of the lock body 1 is provided with a guide ridge 12, and the slider 2 is provided with a guide groove 23, which is engaged with the guide ridge 12. In addition, a blocking portion 13 is provided at one end of the lock body 1 to block the slider 2 from sliding out of the end, thereby achieving that the slider 2 can only slide out along one end of the lock body 1. The two ends of the wire rope assembly 5 are respectively connected to the slider 2 and the lock seat 6. Specifically, the slider 2 is provided with a first mounting hole 21, and the lock seat 6 is provided with a second mounting hole 61; the two ends of the wire rope assembly 5 pass through the first mounting hole 21 and the second mounting hole 61 respectively, and a limiting sleeve 52 is provided at the end of both ends, and the diameter of the limiting sleeve 52 is larger than the aperture of the first mounting hole 21 and the second mounting hole 61; it should be noted that the limiting sleeve 52 is fixed to the two ends of the wire rope assembly by riveting, that is, after the wire rope assembly 5 passes through the first mounting hole 21 and the second mounting hole 61, it continues to be pulled outwards to a sufficient length, which is sufficient to meet the length of the limiting sleeve 52 and the riveting, and after the riveting, it is pulled out again, and is limited by the limiting sleeve 52 That is it; thus, the limiting sleeve 52 can withstand a higher pulling force and will not fall off the wire rope, and the limiting sleeve limits the wire rope assembly 5 from coming off the slider 2 and the lock seat 6; the spring sheet 3 is ∠-shaped, and its hypotenuse end is the free end 31, and the spring sheet 3 is received in the accommodating groove 11, and the free end 31 extends out of the accommodating groove 11. The size of the accommodating groove 11 is sufficient to allow the spring sheet 3 to be relatively stably embedded therein without interfering with the movement of the free end 31; the slider 2 is provided with a limiting portion 24 on the side where the lock body 1 is located, and the free end 31 abuts against the limiting portion 24 to limit the sliding of the slider 2; only when the external force causes the free end 31 of the spring sheet 3 to move into the accommodating groove 11 and the restriction on the limiting portion 24 is released, the slider 2 can slide out from one end of the lock body 1. Specifically, the present embodiment further includes a key 8, which includes a key rod 81, and a key head 82 is disposed on the key rod 81; a key passage 22 is provided on the slider 2, and the key 8 is inserted through the key passage 22, and the key 8 is turned, so that the key head 82 presses the spring sheet 3 to force the free end 31 to move into the receiving groove 11, Fig. 9 As shown by the dotted line 31', the free end 31 moves downward and is no longer in contact with the end 24a of the limiting portion 24, so that the slider 2 can slide to the right (facing the Fig. 9 In addition, in order to allow the free end 31 to slide smoothly during the contact with the limiting portion 24, the end of the free end 31 is preferably bent inwardly in this embodiment so that the end of the free end 31 forms an arc transition 311, so that it can slide smoothly during the movement and avoid the problem of jamming and unsmooth opening.
[0027] Of course, as the key 8 rotates, the key head 82 contacts the spring sheet, and in the process of squeezing the spring sheet, the spring sheet will use a reaction force to push the key 8 upward, thereby weakening the squeezing of the spring sheet, so that the spring sheet cannot fully elastically deform into the accommodating groove 11; for this reason, the present embodiment also includes a key anti-retraction component, which includes a limit baffle 9, and a lock hole 91 is opened on the limit baffle 9; a positioning ridge 83 is provided on the key rod 81, and the key 8 is inserted through the lock hole 91, and in the process of turning the key 8 to contact the spring sheet, the positioning ridge 83 rotates past the position of the lock hole and is restricted in the key channel 22, and the upper end is axially limited by the limit baffle 9 to limit it from escaping from the lock hole 91, so there is no need to apply downward pressure to the key by hand, and only the key needs to be driven to rotate, which makes it easier to open the door.
[0028] In addition, if the wire rope assembly is directly exposed, it may scratch the doors and windows, and it is not very beautiful. For this reason, the wire rope assembly 5 is preferably provided with a protective cover 51 on the outside of the embodiment. The protective cover 51 can be made of flexible materials such as silicone, PE, polyurethane, etc.
[0029] Of course, after the lock body 1 and the lock seat 6 are fixedly installed on the door and window by the screws 10, the head end and the internal structure of the lock body 1 and the lock seat 6 will be exposed to the outside. For this reason, the first decorative cover 4 and the second decorative cover 7 are respectively buckled on the outside of the two to shield the inside. On the one hand, it prevents the sharp parts inside from scratching the user, and on the other hand, it can improve the integrity and aesthetics. Of course, it should be noted that the first decorative cover 4 is provided with a necessary key avoidance hole to ensure that the key can be inserted smoothly. The first decorative cover 4 and the second decorative cover 7 can be buckled on the lock body 1 and the lock seat 6 by the claw and groove structure in the prior art to achieve their installation and fixation, as well as later disassembly and maintenance. This is no different from the prior art and will not be repeated here.
[0030] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
