The outer sleeve of the rotating shaft is provided with a spring. Rotating the rotating shaft can drive the rotating shaft to rotate, and the spring can achieve the function of extension and contraction, which can tighten the cabinet door and play the role of preventing loosening and shock.

[0003] In response to different requirements of this type of lock in use, the applicant has made a series of improvements. For example, in CN219298986U, the lock buckle is sleeved on the tensioning mechanism, which is sleeved on the rotating shaft and fixed to the panel seat. The tensioning mechanism has the effect of tightening the lock bolt and buffering, waterproofing and shockproofing. CN219298984U tightens the lock bolt with the help of a spring to prevent the handle from rotating.

[0004] However, for some special vehicles, especially heavy vehicles such as pickup trucks, their operating environment is more complex and severe, and the car cabinets and tool boxes are subject to severe vibrations. Conventional locks cannot meet the security requirements of these applications.

[0005] In view of this, this application is made. Utility Model Content

[0006] In view of this, the present application provides a panel-type tension lock, which can not only achieve stable locking of the lock to meet the safety requirements of use, but also achieve limited locking of the pressure plate to prevent the latch from being disengaged due to vibration.

[0007] Specifically, the present application is implemented through the following scheme:

[0008] A panel type tension lock, comprising a base, a handle, a lock core assembly, a dial plate, a torsion spring, a rolling sleeve and a clamping plate.

The torsion spring drives the shift plate to reset, thereby resetting the latch. More preferably, the shift plate is provided with a shift piece, which is connected to the latch, and when the shift plate rotates, the shift fork drives the latch to rotate accordingly. A torsion spring seat is provided on the base, and a connecting hole is provided on the torsion spring seat, and the torsion spring is connected between the torsion spring seat and the shift plate through the connecting hole.

[0022] The two sides of the handle rotating around the rotating shaft have different mating surfaces, and the side away from the lock core assembly is higher than the side close to the lock core assembly. By means of the height difference between the handle and the cavity mating surface, a tightening effect can be achieved to avoid loosening caused by shaking.

[0023] The card slot is a square slot, which realizes quantitative control of the rotation direction at 90°. More preferably, a group of card blocks are arranged at the lower end of the card plate, and the card slot is formed between the card blocks. The card slot is formed by the card block method, which makes the card plate processing more convenient, the card slot structure more stable, and prevents the card slot from being deformed and inaccurately positioned due to the extension of use time and / or the increase of frequency.

[0024] The above scheme realizes the fixed-angle rotation of the roller sleeve, and the tensioning and locking are stable, avoiding the problem of inaccurate locking state caused by vibration and shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The panel type tension lock provided in this embodiment is combined with Figure 1 , Figure 2 , including a base 1, a handle 2, a lock core assembly 3, a dial plate 4, a torsion spring 5, a rolling sleeve 6 and a clamping plate 7.

[0039] The base 1 has a cavity on the outward side for convenient installation of the handle 2, lock core assembly 3, etc. The cavity is formed by a depression inwardly from the surface of the base 1. Two installation grooves are respectively provided in the cavity, and the handle 2 and lock core assembly 3 are respectively installed on the base 1 through the installation grooves.

[0040] Specifically, combined with Figure 3 , Figure 4 :

[0041] A rotating shaft 21 is installed at the upper installation groove through a seat sleeve 23. One end of the rotating shaft 21 is connected to the handle 2 through a rivet pin 22, and a pin hole 211 is provided on the side wall of the other end. The rotating shaft 21 is connected to the connecting shaft 25 through a pin 29 inserted into the pin hole 211.

[0042] The connecting shaft 25 is a square shaft, and the card plate 7 and the protective mask 72 are respectively provided with square grooves matching the outer diameter of the square shaft. The card plate 7 and the protective mask 72 are respectively mounted on the connecting shaft 25, so that the card plate 7 is located on the back side of the base 1, and the protective mask 72 is located on the card plate 7. A gasket is mounted on the connecting shaft 25 protruding outside the protective mask 72 and is fastened with a locking nut 26 to prevent the protective mask 72 from shaking relative to the card plate 7 during use.

[0043] A compression spring 28 is sleeved on the connecting shaft 25 between the clamping plate 7 and the base 1 . The upper end of the clamping plate 7 is higher than the base 1 . A rolling sleeve 6 is arranged at the upper end. A clamping groove formed by a clamping block 71 is arranged at the lower end of the clamping plate 7 .

[0044] Combination Figure 5 , Figure 6 :

[0045] A lock core assembly 3 is installed at the lower installation groove through a lock core seat 31 , and a latch 32 and a paddle 4 are respectively provided at one end of the lock core assembly 3 located on the back side of the base 1 .

[0046] The latch 32 is connected to the lock core assembly 3 and rotates with the lock core assembly 3. A torsion spring seat 52 is provided on the back side of the base 1 corresponding to the latch 4. The torsion spring seat 52 is fixed to the base 1 by screws (not marked in the figure). Mounting holes 53 are provided on the paddle 41 and the torsion spring seat 52. The movable ends of the torsion spring 5 are respectively inserted into the two mounting holes 53, so that the torsion spring 5 is connected between the torsion spring seat 52 and the paddle 41.

[0047] The dial plate 4 is fixedly mounted on the end of the lock core assembly 3 at the back side of the base 1 by means of a combination screw 42 , and the latch 32 is located between the dial plate 4 and the base 1 .

[0048] The paddle plate 4 is provided with a paddle 41 protruding toward the latch 32, and the paddle plate 4 is movably connected to the latch 32 by means of the paddle 41. Figure 4The surface of the middle latch 32 is provided with a U-shaped protrusion, and the corresponding paddle 41 is correspondingly protruded. When the paddle 4 rotates with the lock core assembly 3, the paddle 41 can push the U-shaped protrusion to move in the same direction, so that the latch 32 can rotate with the lock core assembly 3 to Figure 6 When resetting, the torsion spring 5 recovers its deformation and the paddle 41 is pulled back to its original position, and the latch is no longer subjected to force and automatically falls to Figure 4 position.

[0049] In the above scheme, combined with Figure 6 When the handle 2 is pressed down, the fitting surfaces of the handle 2 on both sides of the shaft 21 and the chamber are respectively denoted as M and N, wherein the fitting surface corresponding to M is located on the side of the shaft 21 close to the lock core assembly 3, and is almost fitted to the bottom of the chamber; the fitting surface corresponding to N is located on the side of the shaft 21 away from the lock core assembly 3, and is close to the top of the chamber; the fitting surface M is lower than the fitting surface N. With the help of the height difference of the fitting surface of the handle 2 relative to the chamber, when shaking occurs, the side wall of the chamber interacts with the handle 2 to achieve the tightening effect of the shaft 21, thereby avoiding the loosening of the shaft 21 and the connection 25 directly connected thereto and the card plate 7 indirectly connected thereto caused by the shaking.

[0050] As an alternative: Combine Figure 1 , Figure 3 , a cover plate 24 is provided on the handle 2, and the cover plate 24 is located above the lock core assembly 3. The cover plate 24 covering the lock core assembly 3 can protect the lock core assembly 3 and prevent environmental factors from interfering with the lock core assembly 3 when the lock is not unlocked. Preferably: a gasket 15 is provided on the inner side of the cover plate 24, and the gasket 15 can be set in an elastic sponge, which can be used as a sealing gasket to seal and waterproof the lock core assembly 3, and can also be used as a buffer to prevent the cover plate 24 from mechanically damaging the lock core assembly 3 when the handle 2 is pulled up and put down.

[0051] In the above scheme, combined with Figure 2 , Figure 5 One or two or more groups of knurled pins 73 may also be provided on the protective mask 72, and the knurled pins 73 may be installed with locking rods, pull rods and other components to serve as reserved locking points for auxiliary locking.

[0052] In the above scheme, combined with Figure 1 , Figure 2 A pressing plate 61 is installed on the upper end of the cardboard 7, and the pressing plate 61 is arranged perpendicular to the cardboard 7. The rolling sleeve 6 is installed on the pressing plate 61 to realize the installation of the rolling sleeve 6 on the upper end of the cardboard 7. Preferably, a slot 62 is arranged on the pressing plate 61, and the rolling sleeve 6 is fixed at different positions of the slot 62 by bolts. By adjusting the screwing in and out of the bolts, the height adjustment of the rolling sleeve 6 and the position adjustment in the slot 62 can be realized to adapt to different cabinet thicknesses and space requirements.

[0053] In the above scheme, combined with Figure 1 , Figure 2 There are two groups of blocks 71, and the angle between the first group and the second group is 90°. With the action of the latch 32, the rotation direction of the card plate 7 is controlled within a quantitative range of 90°, and the positioning is accurate.

[0054] In the above scheme, when in the locked state, Figure 6 , Figure 7 As a reference, the handle 2 is pressed down in the chamber, the cover plate 24 covers the top of the lock core assembly 3, the compression spring 28 between the base 1 and the card plate 7 is in a stretched state, the card plate 7 is in a vertical state, the roller sleeve 6 faces upward, the latch 32 is buckled upward in the slot formed by the card block 71, the rotating shaft 21, the roller sleeve 6 and the cabinet are all in a locked state, and the handle 2 is also locked in the chamber.

[0055] Combination Figure 6 A lining plate 13 can be fixed on the back side of the base 1 to strengthen the strength of the base 1, and O-rings 14 can be arranged between the base 1 and the lining plate 13, between the seat cover 23 and the base 1, and between the lock core seat 31 and the base to enhance the installation stability and sealing.

[0056] When unlocking is required, the handle 2 is pulled outward, and the handle 2 is separated from the tension state between the chamber and the handle. The handle 2 can be rotated along the rivet pin 22 to a state in a straight line with the rotating shaft 21, exposing the lock core assembly 3. Under the outward pulling action of the handle 2, the card plate 7 is pulled close to the base 1 along with the rotating shaft 21 and the connecting shaft 25, and the compression spring 28 is stretched and deformed to recover; the key is inserted into the lock core assembly 3 and rotated, and the lock core assembly 3 drives the dial plate 4 fixed thereto to rotate, and the dial plate 4 drives the latch 32 to rotate to the lock core assembly 3 through the dial 41. Figure 5 In the horizontal state shown, the torsion spring 5 is in a stretched deformation state, the latch 32 is out of the slot, the clamping plate 7 and the rotating shaft 21 are in a loose and rotatable state, and the handle 2 is turned. The handle 2 drives the clamping plate 7 to rotate to 90° via the rotating shaft 21 and the connecting shaft 25, and the roller sleeve 6 at the upper end of the rotating shaft 21 rotates to a horizontal state, and the roller sleeve 6 is out of the direction of the cabinet door to complete the unlocking.

[0057] When locking is required, the key is rotated in the opposite direction, and the latch 32 is reset to the upward state under the action of the dial plate 4 and the torsion spring 5. The handle 2 is turned, and the shaft 21 drives the connecting shaft 25 and the card plate 7 to rotate until the roller sleeve 6 faces upward, and the cabinet door position is initially locked; the handle 2 is pushed to make it fall back into the chamber, the compression spring 28 is stretched, and the card slot is also buckled on the reset latch 32, completing the locking of the shaft 21, and the cover plate 24 covers the lock core assembly 3 from which the key has been removed, completing the locking.

[0058] The above solution realizes the fixed-angle rotation of the roller sleeve 6, and the tensioning and locking are stable, thus avoiding the problem of inaccurate locking state caused by vibration and shaking.

[0059] The roller sleeve 6 of the tension lock in this case can be adjusted up and down, and when used for locking the panel parts of heavy vehicles such as pickup trucks, it has the advantages of stable operation, safety and reliability, and precise rotation angles of the clamping plate 7 and the roller sleeve 6.
