Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch and lock technology, and specifically relates to a guardrail switch and lock. Background Technology
[0002] Children's gates and fences are safety barriers designed to protect children. Once locked, they restrict children's movement to a safe area and are widely used as safety barriers around beds, door frames, or on the ground.
[0003] Existing child safety gate locks typically employ a single locking mechanism, such as a simple pin or hook structure. While these locks can meet basic protection needs to a certain extent, they still pose numerous safety hazards in actual use. On the one hand, the simple locking structure allows children to easily open the lock by imitating adult actions or accidentally touching it, rendering the gate ineffective and increasing the risk of children falling and getting injured or entering dangerous areas. On the other hand, over long-term use, the locking mechanism can easily become loose and worn due to children's frequent climbing and shaking of the gate, reducing the reliability of the lock.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides, for example Figure 1-4 The guardrail switch lock shown includes:
[0024] The lock body 1 has a tail fixing block 2 connected to one end and a bottom fixing block 3 connected to the bottom. The other end of the lock body 1 is provided with a lock head 4. The lock body 1 is provided with a switch lock assembly that cooperates with and locks the lock head 4. By pushing the push block 5 of the switch lock assembly, the first lock piece 6 is moved, so that when the first lock piece 6 moves, the second lock piece 7 is moved.
[0025] The third locking element 8 is located at the bottom of the second locking element 7 and is used to indicate the unlocked status when the second locking element 7 moves the third locking element 8.
[0026] The switch lock assembly includes a spring 9. The first lock member 6, the second lock member 7, and the third lock member 8 are all slidably connected inside the lock body 1. The push block 5 is slidably connected to the surface of the lock body 1 and the bottom of the push block 5 is connected to the first lock member 6. The bottom of the first lock member 6, the second lock member 7, and the third lock member 8 are all connected to a fixing buckle 10.
[0027] The second locking member 7 and the third locking member 8 are both provided with a fixing groove 11 at the top. The fixing buckle 10 at the bottom of the first locking member 6 is inserted into the fixing groove 11 at the top of the second locking member 7, and the fixing buckle 10 at the bottom of the second locking member 7 is inserted into the fixing groove 11 at the top of the third locking member 8. The fixing buckle 10 at the bottom of the third locking member 8 is slidably connected to the sliding groove provided in the lock body 1. The slidable connection between the fixing buckle 10 at the bottom of the third locking member 8 and the sliding groove in the lock body 1 not only provides guidance for the movement of the third locking member 8, but also ensures its stability during the movement process and prevents deviation or jamming.
[0028] The spring 9 is provided in three sets, and one end of the three sets of spring 9 is connected to the first locking member 6, the second locking member 7, and the third locking member 8 respectively, and the other end is connected to the lock body 1. The lock head 4 is provided with two sets of lock grooves 18, and one end of the first locking member 6 and the second locking member 7 are respectively inserted into the two sets of lock grooves 18.
[0029] The surface of the third locking component 8 is provided with a first observation area 12 and a second observation area 13, and the surface of the lock body 1 is provided with an observation window 14. The colors of the first observation area 12 and the second observation area 13 are red and green, respectively.
[0030] The lock body 1 is provided with a first limiting hook 15 at one bottom end, and the lock head 4 is provided with a second limiting hook 16 at one bottom end. When the first limiting hook 15 and the second limiting hook 16 are in contact, the relative displacement between the lock head 4 and the lock body 1 can be restricted.
[0031] The lock body 1 and lock head 4 are provided with several threaded holes 17 on their surfaces. The lock body 1 and lock head 4 can be fixed to the guardrail by screws that pass through the threaded holes 17.
[0032] When unlocking this guardrail switch lock, the user pushes the push block 5 to move it away from the lock head 4. The push block 5 causes the first locking member 6 to slide into the lock body 1. During the movement of the first locking member 6, the fixing buckle 10 at its bottom pulls the second locking member 7, causing the second locking member 7 to also move into the lock body 1. The movement of the second locking member 7 causes the third locking member 8 to slide into the lock body 1 simultaneously. The spring 9 is gradually compressed. When the first locking member 6 and the second locking member 7 disengage from the lock groove 18, the first locking between the lock head 4 and the lock body 1 is released. As the third locking member 8 moves, the state displayed on its surface in the observation window 14 changes to red, i.e., the first observation area 12, indicating that the lock has been successfully unlocked. At this time, the first locking member 6 and the second locking member 7 have disengaged from the lock groove 18, and the guardrail can be opened, ensuring the safety and accuracy of the unlocking operation.
[0033] When the railing needs to be locked, release the push block 5. The spring 9 rebounds, causing the first locking piece 6, the second locking piece 7, and the third locking piece 8 to move together. One end of the first locking piece 6 and the second locking piece 7 are respectively inserted into the two sets of locking grooves 18 in the lock head 4, achieving double locking. At the same time, when the third locking piece 8 contacts the lock head 4, the state displayed on its surface in the observation window 14 changes to green, which is the second observation area 13, indicating to the user that the lock is in the locked state.
[0034] When the first locking piece 6 and the second locking piece 7 are not correctly inserted into the two sets of locking slots 18, the state displayed on the surface of the third locking piece 8 in the observation window 14 changes to red and green, indicating that both the first observation area 12 and the second observation area 13 are red and green, indicating to the user that the lock is in a failed locking state.
[0035] Meanwhile, the first limiting hook 15 at the bottom of the lock body 1 and the second limiting hook 16 at the bottom of the lock head 4 cooperate with each other when locked, further restricting the relative displacement between the lock head 4 and the lock body 1, so that the lock body 1 can only open and close and rotate forward or backward, but cannot move left or right, thereby enhancing the overall stability of the lock.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
