Description

Technical Field

[0001] The utility model relates to the technical field of door padlock products, in particular to a safety buckle hand lock with double lock tongues. Background Art

[0002] Traditional furniture or electrical appliances, especially steel doors, are generally provided with a buckle or handle structure on the door body for easy opening. Door locks generally include door locks with door handles and door locks with driven buckles. When using door locks with door handles, the door handles are externally placed, which often affects people's movement or work due to their own structure, and are not conducive to the company's processing, packaging and laminating operations on the cabinet.

[0003] Padlocks are the oldest and largest family of locks in the world. It can be said that other locks are derived from padlocks. The lock body of a padlock is equipped with a ring-shaped or "I"-shaped metal stem, namely the "lock beam", which allows the padlock to be directly connected to the lock body through the lock beam to form a closed lock.

[0004] As an example of the prior art, referring to the patent document CN307520222S, it can be inferred from its various views that the fixed plate and the movable plate at the front end of the lock shell can be connected to the padlock to achieve locking. After unlocking the padlock, the movable plate is rotated, and the lock body at the rear end of the lock shell can rotate with the movable plate, thereby switching from the locked state to the unlocked state. However, the existing door padlocks have relatively simple functions, for example: 1. Its locking function only relies on the padlock. Once the padlock is removed, the entire lock will not have the locking or position holding function; 2. When used as a public cabinet, it lacks an indication function; 3. The locking strength is not high, and the force point is relatively concentrated when the external force is forced to open, so it is easy to be damaged. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a safety hand lock with double locking tongues.

[0006] The utility model solves the technical problem by providing a safety hand lock with double locking tongues, comprising:

[0007] The lock shell has at least a padlock space, a first lock tongue space and a second lock tongue space, and the front end of the lock shell is provided with a hand buckle groove and a work card area;

[0008] A door padlock assembly, which is assembled on the lock housing, and the door padlock assembly has a lock hole, and the lock hole is exposed in the padlock space of the lock housing;

The first lock tongue has at least a first locked position and a first unlocked position. The first lock tongue is connected to a lock body, and the lock body is at least partially exposed in the padlock space of the lock housing.

[0010] A second locking tongue, which is located in the second locking tongue space, has at least a second locking position state and a second unlocking position state, and can extend outward or retract inward along the second locking tongue space;

[0011] When the lock hole on the door padlock assembly is connected to an external padlock, the door padlock assembly restricts the movement of the lock body, thereby keeping the second lock tongue in the second locking position through the lock body;

[0012] The lock hole can be connected to a replaceable padlock, and the work badge area can be connected to a replaceable identification work badge.

[0013] A preferred embodiment of the utility model further comprises a reset spring sheet, which acts on the first locking tongue so that the first locking tongue is always reset to a movement trend toward the locked position state.

[0014] A further configuration of the preferred embodiment is that a concave arc section is provided at the end of the first lock tongue, and a positioning protrusion is provided in the first lock tongue space;

[0015] One end of the reset spring sheet is pressed against the concave arc section, and the other end is wound around the positioning protrusion.

[0016] Further, the door padlock assembly comprises a fixed plate and a movable plate, and the lock hole passes through the fixed plate and the movable plate;

[0017] The fixing plate is fixedly connected to the lock housing;

[0018] The movable plate is connected to the lock body and can rotate together with the lock body to drive the first lock tongue to rotate through the lock body.

[0019] Another preferred embodiment of the utility model is that it further includes a return spring, which acts on the second locking tongue so that the second locking tongue always has a movement tendency to extend outward.

[0020] In the utility model, a guide rib is protruded on one side of the lock shell facing the second lock tongue space, a guide groove is provided on the second lock tongue, and the guide rib is slidably arranged in the guide groove.

[0023] Furthermore, a plurality of convex ribs are provided inside the slot, and the convex ribs abut against the upper end of the decorative cover plate to form an interference fit.

[0024] Preferably, the second locking tongue has a first guiding arc surface and a second guiding arc surface.

[0025] The beneficial effects of the utility model are:

[0026] 1. It is suitable for padlocks and has the functions of padlock locking, first lock tongue locking and second lock tongue locking to achieve triple locking effects. The locking combinations are richer, the locking effects are better, and the structural strength and safety are higher.

[0027] Second, the hand lock can be reused. The keyhole can be connected to a replaceable padlock, and the work badge area can be connected to a replaceable identification badge, so that the padlock and the identification badge can be matched one by one. When the previous user leaves, the padlock and identification badge are detached; the next user can bring a new padlock and identification badge to re-match the hand lock.

[0028] 3. The padlock and the first lock tongue prevent locking and theft; the second lock tongue maintains the state, prevents wind and shake.

[0029] 4. The door padlock assembly can serve two purposes: one is that it can be connected to an external padlock to lock and prevent theft; the other is that

[0030] 5. With the help of a multiple locking structure, there are multiple force points, so the force can be more dispersed when the lock is opened violently, so as to reduce the probability of deformation and damage of various components and improve the overall strength and service life of the lock.

[0045] Embodiment 1

[0046] Reference Figures 1 to 10 A safety hand-buckle lock with double lock tongues comprises: a lock shell 1, which has at least a padlock space 101, a first lock tongue space 102 and a second lock tongue space 103, and the front end of the lock shell 1 is provided with a hand-buckle groove 104 and a work card area 105; a door padlock assembly 2, which is assembled on the lock shell 1, and the door padlock assembly 2 has a lock hole 201, and the lock hole 201 is exposed in the padlock space 101 of the lock shell 1; a first lock tongue 3, which is rotatably connected to the lock shell 1 and is located at the second lock tongue space 103. In a lock tongue space 102, the first lock tongue 3 has at least a first locked position state 3a and a first unlocked position state 3b, and the first lock tongue 3 is connected to a lock body 301, and the lock body 301 is at least partially exposed in the padlock space 101 of the lock shell 1; the second lock tongue 4 is located in the second lock tongue space 103, and the second lock tongue 4 has at least a second locked position state 4a and a second unlocked position state 4b, and can extend outward or retract inward along the second lock tongue space 103. The above content is the basic structural scheme of the utility model, and the specific situation when it is used is: 1. When the lock hole 201 on the door padlock assembly 2 is connected to the external padlock 5, the door padlock assembly 2 limits the movement of the lock body 301, and then the second lock tongue 4 is kept in the second locking position state 4a through the lock body 301; 2. The lock hole 201 can be connected to a replaceable padlock 5, and the work card area 105 can be connected to a replaceable identification card 1051, so that the padlock 5 and the identification card 1051 correspond one to one. When the previous user leaves, the padlock 5 and the identification card 1051 are detached; the next user can bring a new padlock 5 and identification card 1051 to re-match the hand lock.

[0047] The utility model has double lock tongues, which can be used with a padlock 5 to achieve a better locking effect. The padlock 5 and the first lock tongue 3 can prevent locking and theft, while the second lock tongue 4 can maintain the state, prevent wind and prevent shaking.

[0048] The operation of the utility model is as follows: the user first unlocks the padlock 5 on the lock hole 201 and removes the padlock 5, and then drives the lock body 301 to operate through the door padlock assembly 2, and drives the first lock tongue 3 to switch from the first locked position state 3a to the first unlocked position state 3b through the lock body 301, and finally the user's hand reaches into the hand buckle groove 104 and pulls, so that the second lock tongue 4 contacts the support body (door body or cabinet body) and is subjected to force. After the force is applied, the second lock tongue 4 switches from the second locked position state 4a to the second unlocked position state 4b, so that the entire lock is separated from the support body (door body or cabinet body) to achieve unlocking.

[0049] In the present invention, the lock housing 1 is provided with a guide rib 106 on one side facing the second lock tongue space 103, and the second lock tongue 4 is provided with a guide groove 401, and the guide rib 106 is slidably arranged in the guide groove 401. The cooperation between the guide rib 106 and the guide groove 401 plays a guiding and anti-shaking role, so that the second lock tongue 4 is more stable and reliable in the process of extending outward or retracting inward.

[0050] Preferably, the second lock tongue 4 has a first guide arc surface 402 and a second guide arc surface 403, forming a double-sided guiding effect, so that either side of the second lock tongue 4 can retract the second lock tongue 4 backward when subjected to force, so as to switch from the second locked position state 4a to the second unlocked position state 4b.

[0051] Embodiment 2

[0052] Based on the structure of the first embodiment, in order to enable the first locking tongue 3 and the second locking tongue 4 to automatically reset after use, refer to Figure 6-7 , the preferred structure adopted is as follows:

[0053] 1. A reset spring 7 is included, which acts on the first locking tongue 3 so that the first locking tongue 3 is always reset to a movement trend toward the locked position state.

[0054] Specifically, a concave arc section 302 is provided at the end of the first lock tongue 3, and a positioning protrusion 1021 is provided in the first lock tongue space 102; one end of the reset spring 7 is abutted against the concave arc section 302 as a deformable active end; the other end is wrapped around the positioning protrusion 1021 as a fixed end.

[0055] When the first lock tongue 3 is subjected to force and rotates to unlock, the concave arc section 302 will squeeze one end of the reset spring piece 7 to deform it; when the lock body 301 is released, the first lock tongue 3 automatically resets to the first locked position state 3a under the elastic force of the reset spring piece 7.

[0056] Second, a return spring 8 is included, which acts on the second locking tongue 4 so that the second locking tongue 4 always has a tendency to move outward.

[0057] Embodiment 3

[0058] Based on the structure of any of the above embodiments, this embodiment optimizes and improves the local structure. Figure 3 to Figure 6 Specifically, the door padlock assembly 2 includes a fixed plate 202 and a movable plate 203, and the lock hole 201 passes through the fixed plate 202 and the movable plate 203; the fixed plate 202 is fixedly connected to the lock shell 1; the movable plate 203 is connected to the lock body 301 and can rotate together with the lock body 301 to drive the first lock tongue 3 to rotate through the lock body 301.

[0059] Therefore, when the padlock 5 is removed from the door padlock assembly 2, the restriction on the movable plate 203 can be released, and then the movable plate 203 is moved to rotate relative to the fixed plate 202. The rotation of the movable plate 203 causes the lock body 301 to rotate, and then the lock body 301 drives the first lock tongue 3 to switch it from the first locked position state 3a to the first unlocked position state 3b.

[0060] In addition, the padlock 5 can only be installed when the lock hole 201 on the movable plate 203 is aligned with the lock hole 201 on the fixed plate 202; the padlock 5 cannot be inserted when they are misaligned.

[0061] Embodiment 4

[0062] In this embodiment, a decorative cover plate 6 is also included for shielding some components, as follows: Fig.10 The lower section of the first lock tongue space 102 is provided with a positioning groove 1022, the upper end of the first lock tongue space 102 is provided with a clamping groove 1023, the lower end of the decorative cover plate 6 is inserted into the positioning groove 1022, and the upper end of the decorative cover plate 6 is embedded in the clamping groove 1023.
