Detailed Embodiment
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Application description: In the process of building a house, sliding windows need to be used. The safety lock provided by the present utility model is specifically used for the safety protection inside the house. During the use of this safety lock, it is necessary to check in advance whether the spring can be stretched and contracted regularly to ensure the normal installation of the safety lock.
[0022] Such as Figure 1 - Figure 4As shown in the figure, the present utility model provides a technical solution: a safety lock for a sliding window, including a lock body 1. A buckle groove 2 is provided on the upper end surface of the lock body 1. Two limiting grooves 8 are symmetrically provided at both ends of the lock body 1. Two through grooves 7 are symmetrically provided on the upper end surface of the lock body 1. Two fixing plates 9 are symmetrically and fixedly installed on the inner wall of the lock body 1. A spring 10 is fixedly installed on the outer wall of the fixing plate 9. The other end of the spring 10 is fixedly installed with a limiting insertion block 3. One end of the limiting insertion block 3 penetrates through the limiting groove 8 and extends to the outer wall of the lock body 1. A connecting rod 15 is fixedly connected to the upper end surface of the limiting insertion block 3. The upper end of the connecting rod 15 penetrates through the through groove 7 and extends to the outer wall of the lock body 1.
[0023] Through the settings of the limiting groove 8, the through groove 7, the fixing plate 9, the spring 10, the buckle groove 2, and the connecting rod 15, in the process of using by the staff, by pulling the two connecting rods 15, the spring 10 can be contracted, so as to control the expansion and contraction of the limiting insertion block 3, and fix the safety lock on the outer wall of the sliding window, which is more convenient for installation.
[0024] As Figure 3 shown, a limiting rod 11 is provided on the inner wall of the spring 10. The end of the limiting rod 11 is fixedly connected to the outer wall of the limiting insertion block 3. The other end of the limiting rod 11 penetrates through the fixing plate 9 and extends to the outer wall of the fixing plate 9.
[0025] By setting the limiting rod 11, in the process of using, it can play a role in limiting the spring 10 and the limiting insertion block 3, preventing the spring 10 from deforming during use, thus affecting the normal use of the safety lock of the present application.
[0026] As Figure 4 shown, two limiting holes 14 are symmetrically provided on the upper end surface of the pulling block 4. A limiting block 12 is slidably connected to the inner wall of the limiting hole 14.
[0027] By setting the limiting hole 14 and the limiting block 12, in the process of using, the limiting block 12 plays a role in limiting the pulling block 4, preventing the pulling block 4 from being accidentally touched during use, so that the lock falls off the sliding window.
[0028] As Figure 1 shown, a connecting block 5 is fixedly connected to the upper end surfaces of the two limiting blocks 12.
[0029] By setting the connecting block 5, in the process of using, by pulling the connecting block 5, the two limiting blocks 12 can be taken out of the limiting hole 14 together, which is more convenient for use.
[0030] As Figure 4 shown, rubber rings 13 are fixedly installed on the outer walls of the two limiting blocks 12. The outer wall of the rubber ring 13 is slidably connected to the inner wall of the limiting hole 14.
[0031] By providing the rubber ring 13 , the design can increase the friction between the limiting block 12 and the limiting hole 14 during use, and can fix the limiting block 12 more tightly.
[0032] like Figure 1 As shown, a rotating block 6 is rotatably connected to a position of the upper end surface of the lock body 1 corresponding to the connecting block 5 , and the bottom of the rotating block 6 abuts against the upper end surface of the connecting block 5 .
[0033] By providing the rotating block 6, the design can limit the connection block 5 by the rotating block 6 during use, which is more convenient to use.
[0034] like Figure 1 As shown, the outer walls of the two limiting plug blocks 3 are both provided with chamfers.
[0035] By setting a chamfer on the outer wall of the limiting plug 3, this design makes it easier for workers to insert the limiting plug 3 into the sliding window during use, making installation more convenient.
[0036] Working principle:
[0037] When the staff of the utility model is in use, when the safety lock needs to be replaced, the staff rotates the two rotating blocks 6 to make the rotating blocks 6 leave the connecting block 5, and then the staff pulls the two connecting blocks 5, and the two limit blocks 12 are pulled out from the limit holes 14, and then the staff moves the two pulling blocks 4 to make the spring 10 contract, and the limit plug block 3 is stored into the interior of the lock body 1, and then the lock body 1 is taken out from the groove, which is more convenient to install.
[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
