Technical Field

[0001] The present application relates to the technical field of locks, and in particular to a panel lock. Background Art

[0002] At present, panel locks are widely used in various industries, such as generator sets, trucks, etc. The panel lock usually has a handle that can be folded and installed in the groove of the lock seat, and the handle can be pulled up from the groove to rotate the lock tongue.

[0003] In addition, a lock body fixed by a lock body nut is also installed in the lock seat, and a lock core controlled by a key is arranged in the lock body. A shift block is fixed to the front end of the lock core, and a lock plate controlled by the shift block is slidably provided on the inner side of the lock seat. The shift block controlled by the lock core can lock the lock tongue by pushing the lock plate to move, such as the locking structure of the lock shown in the existing publication number CN117759115A, which realizes the locking function of the lock tongue by plugging the lock plate (i.e., lock tongue 115) into the positioning plate.

[0004] The existing method of locking the positioning plate by using a sliding locking plate, when the positioning plate rotates, the locking plate and the positioning plate are mainly in line contact. After long-term use, the sliding locking plate is prone to loosening and wear, causing the positioning plate and the locking plate to be easily misaligned up and down, affecting the locking effect. Utility Model Content

[0005] In order to improve the problem that the lock plate becomes loose and worn after long-term use, and the resulting vertical misalignment of the positioning plate and the lock plate and reduced locking effect, the present application provides a panel lock.

The panel lock also comprises:

[0008] A positioning piece is located between the lock seat and the lock tongue and is fixedly connected to the rotating shaft. The positioning piece includes a positioning plate coaxial with the rotating shaft and two positioning blocks. The two positioning blocks are symmetrically arranged on the outer peripheral side of the positioning plate around the axis of the positioning plate.

[0009] The baffle is fixed on the inner side of the lock seat and blocks the rotation path of the two positioning blocks. When one side of one of the positioning blocks contacts the side of the baffle, the lock tongue is in a locked state; when one side of the other positioning block contacts the side of the baffle, the lock tongue is in an unlocked state.

[0010] The lock body includes a locking plate, which includes a connecting portion fixedly connected to the lock core and controlled by the lock core and a locking portion for locking the lock tongue, and the locking portion extends toward the lock seat; a lock slot is provided at one end of the lock tongue, and the lock tongue is provided with an oblique slot at the lock slot opening for the locking plate to rotate in or out of the lock slot.

[0011] By adopting the above technical solution, the two positioning blocks on the positioning plate cooperate with the fixed baffle to achieve accurate switching of the locking and unlocking states of the lock tongue, solve the problem that the traditional sliding lock plate is easy to loosen and wear, and improve the stability and durability of the locking effect; in addition, the locking part cooperates with the lock groove and the bevel on the lock tongue, and the lock tongue is firmly locked by rotating the lock plate into or out of the lock groove, further enhancing the locking effect and effectively preventing the misalignment of the positioning plate and the lock plate.

[0012] Optionally, a boss is provided at one end of the rotating shaft away from the handle, and the boss is fixed to a screw coaxial with the rotating shaft.

[0013] Optionally, the lock body also includes a lock body nut, a lock cap and a screw. The baffle is provided with a through hole for the lock body to pass through. The lock body passes through the lock cap, the lock seat and the through hole in sequence. The lock body nut is threadedly connected to the lock body and locks the lock body and the baffle to the lock seat.

[0014] Optionally, a reinforcement strip is superimposed on the side of the baffle plate that contacts the positioning block.

[0015] By adopting the above technical solution, the thickness and hardness of the baffle are increased, the ability of the baffle to withstand the impact of the positioning block is improved, and the service life of the panel lock is further extended.

[0016] Optionally, the reinforcement strip is formed by bending the baffle.

[0017] Optionally, at least one group of connection holes is formed on the lock tongue, and each group of connection holes has two connection holes, which are symmetrically distributed around the axis of the rotating shaft.

[0018] Optionally, the locking end of the locking tongue is a transition section with both sides bent toward the middle.

[0019] By adopting the above technical solution, the lock tongue can be helped to transition to a locked state.

[0020] Optionally, one end of the rotating shaft passing through the outer side of the lock seat is sleeved with a gasket and an elastic gasket, and the handle abuts against the gasket.

[0021] By adopting the above technical solution, the setting of the gasket and the elastic pad can provide the handle with a movable space when pulling in and out of the lock seat, and block the gap between the lock seat and the gap through which the rotating shaft is passed, thereby achieving a waterproof effect.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. Since the present invention adopts the cooperation between the two positioning blocks on the positioning plate and the fixed baffle, the accurate switching of the locking and unlocking states of the lock tongue is realized, the problem of easy loosening and wear of the traditional sliding lock plate is solved, and the stability and durability of the locking effect are improved.

[0024] 2. The present invention preferably adopts a locking plate design in the lock body, wherein the locking portion cooperates with the locking groove and the oblique opening on the lock tongue, and the lock tongue is firmly locked by rotating the locking plate into or out of the locking groove, thereby further enhancing the locking effect and effectively preventing the misalignment of the positioning plate and the locking plate.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] In this embodiment, for the convenience of description, the side of the lock base 1 with the groove is called the outer side, and the side of the lock base 1 away from the groove is called the inner side.

[0033] The present application embodiment discloses a panel lock. Figure 1 , 2 The panel lock comprises a lock seat 1, a lock body 2, a handle 3, a rotating shaft 4, a locking tongue 5, a baffle 14 and a positioning piece 6. The rotating shaft 4 passes through the lock seat 1, the handle 3 is rotatably connected to the end of the rotating shaft 4 located outside the lock seat 1 through a pin, the locking tongue 5 is fixedly connected to the end of the rotating shaft 4 located inside the lock seat 1, and the positioning piece 6 is located between the lock seat 1 and the locking tongue 5. When the handle 3 is pulled out of the groove of the lock seat 1 and rotated, the rotating shaft 4 will rotate with the locking tongue 5, thereby controlling the unlocking and locking of the panel lock.

[0034] Reference Figure 2 The end of the rotating shaft 4 passing through the outer side of the lock seat 1 is also sleeved with a gasket 7 and an elastic pad 8, and the elastic pad 8 can be made of a material with elastic deformation ability such as rubber. The arrangement of the gasket 7 and the elastic pad 8 can provide the handle 3 with a movable space when pulling in and out of the lock seat 1, and block the gap between the lock seat 1 and the rotating shaft 4, achieving a waterproof effect.

[0035] Reference Figure 3 , 4 A boss 41 is provided at one end of the rotating shaft 4 away from the handle 3. The boss 41 is in a square structure. A screw 42 coaxial with the rotating shaft 4 is fixed on the boss 41. The locking tongue 5 and the positioning piece 6 are provided with mounting holes 15 adapted to the boss 41. A nut 10 is threadedly connected to the screw 42. During installation, the boss 41 is inserted into the mounting holes 15 of the positioning piece 6 and the locking tongue 5 in sequence, and the screw 42 passes through the mounting hole 15 and is locked by the nut 10, so that the locking tongue 5 and the positioning piece 6 are fixedly connected to the rotating shaft 4.

[0036] Reference Figure 3 The positioning piece 6 includes a positioning plate 61 coaxial with the rotating shaft 4 and two positioning blocks 62. The two positioning blocks 62 are symmetrically arranged on the outer peripheral side of the positioning plate 61 around the axis of the positioning plate 61. The baffle 14 is fixed to the inner side of the lock seat 1, and the position of the baffle 14 just blocks the rotation path of the two positioning blocks 62.

[0037] When one side of one of the positioning blocks 62 contacts the side of the baffle 14, the lock tongue 5 is in a locked state; when the other side of the positioning block 62 contacts the side of the baffle 14, the lock tongue 5 is in an unlocked state. The contact between the positioning block 62 and the baffle 14 is a surface contact. This design not only realizes the accurate switching between the locking and unlocking states of the lock tongue 5, but also improves the service life of the lock.

[0038] Further, see Figure 3A reinforcement strip 16 is provided on the side where the baffle 14 contacts the positioning block 62. The reinforcement strip 16 is formed by bending the baffle 14, which increases the thickness and strength of the contact end of the baffle 14 and the positioning block 62, improves its ability to withstand the impact of the positioning block 62, and further extends the service life of the panel lock.

[0039] Reference Figure 3 , 5 The lock body 2 includes a lock plate 9, a lock body nut 11, a lock cap 12 and a screw, and a through hole 17 is provided on the baffle 14 for the lock body 2 to pass through. The lock body 2 passes through the lock cap 12, the lock seat 1 and the through hole 17 of the baffle 14 in sequence, and then is locked on the lock seat 1 by the lock body nut 11.

[0040] A lock core is also provided in the lock body 2, and the lock plate 9 includes a connecting portion 91 and a locking portion 92, wherein the connecting portion 91 is a disc-shaped structure, and the connecting portion 91 is fixedly connected to the lock core by screws and is controlled by the lock core. The locking portion 92 extends in a length direction parallel to the rotating shaft 4.

[0041] Reference Figure 4 , 5 A locking groove 51 is provided at one end of the lock tongue 5, and an oblique opening 52 is provided at the notch of the lock groove 51 for the lock piece 9 to rotate into or out of the lock groove 51. When the lock tongue 5 is in the locked state, the lock tongue 5 rotates into the lock groove 51, and the locking tongue 5 can be limited. At the same time, the locking portion 92 has a certain length, and the lock tongue 5 is not easy to be misaligned with the locking portion 92, and the locking limit is relatively reliable.

[0042] In addition, at least one group of connecting holes 53 is formed on the lock tongue 5. Each group of connecting holes 53 has two connecting holes, which are symmetrically distributed around the axis of the rotating shaft 4. When the cabinet door is long, these connecting holes 53 can be used to connect the connecting rods at the upper and lower ends of the cabinet door. When the lock tongue 5 is rotated and locked, the connecting rods drive the latches at the upper and lower ends of the cabinet door to be inserted into the door frame, so as to enhance the stability of the cabinet door locking.

[0043] The locking end of the lock tongue 5 is a transition section 54 bent toward the middle on both sides. The inclined surface of the transition section 54 can guide the lock tongue 5, better helping the lock tongue 5 to transition to a locked state during the locking process, and reducing the possibility of jamming and wear.

[0044] The implementation principle of a panel lock in the embodiment of the present application is:

[0045] When the lock tongue 5 switches between the unlocking and locking states, the positioning block 62 and the baffle 14 are in surface contact, and the locking piece 9 is locked by screwing into the locking groove 51, thereby reducing the possibility of misalignment during locking.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
