Description

Technical Field

[0001] The invention relates to the field of locks, and in particular to a single-cylinder motorhome lock. Background Art

[0002] When an RV is used outdoors, it will travel on different road conditions. When the road conditions are poor, the RV will be bumpy, and the components inside the RV lock will vibrate and make abnormal noises, affecting driving comfort. At the same time, long-term vibration of the components will also cause the parts assembly to loosen. During the driving of the vehicle, the lock tongue will detach from the slot of the lock plate, and the door will open, which is very dangerous.

[0003] In response to the above problems, relevant manufacturers produce shockproof locks, such as a shockproof RV lock with a lock tongue with application number CN202121917762.X. In this lock, the switch lock tongue and the safety lock tongue are connected to the cover plate or base through balls and springs. When subjected to vibration, the spring acts as a buffer, reducing the vibration of the lock tongue, avoiding direct hard collision between the lock tongue and the cover plate or base, playing an anti-vibration role, and also avoiding the emission of noise. However, in this type of lock, the switch lock tongue and the safety lock tongue operate separately, and are controlled by two lock cores respectively. There are many parts, and the safety lock tongue cannot control the operation of the switch lock tongue.

The safety lock tongue 4, the connecting rod 5, the connecting sleeve 6, the switch lock tongue 8 and the brake lock bolt 12 are all installed in the installation cavity. Figure 4 , Figure 5 As shown, the outer handle 9 is hinged on the panel 1, and the paddle of the outer handle 9 passes through the panel 1 and is linked to the switch lock tongue 8. The lock core 11 is installed on the outer handle 9 to control the connection state of the outer handle 9 and the panel 1; the inner handle 10 is hinged on the back plate 3, and the paddle of the inner handle 10 passes through the back plate 3 and the base plate 2 and is linked to the switch lock tongue 8. The safety lock tongue 4 is linked to the connecting sleeve 6 through the connecting rod 5; the knob 7 is installed on the back plate 3, passes through the back plate 3 and the base plate 2 and is connected to the connecting sleeve 6. Figure 2 , Figure 3 As shown, the brake bolt 12 is installed between the switch lock tongue 8 and the safety lock tongue 4, so that the movement of the switch lock tongue 8 is restricted by the safety lock tongue 4; when the switch lock tongue 8 and the safety lock tongue 4 are fully extended, the switch lock tongue 8 cannot be retracted, and only when the safety lock tongue 4 is retracted, the extended switch lock tongue 8 can be retracted; when the switch lock tongue 8 and the safety lock tongue 4 are fully retracted, the switch lock tongue 8 can be extended.

[0028] 1. The linkage structure of the switch lock tongue 8.

[0029] like Figure 2 , 3 As shown in , 4, a switch lock tongue 8 mounting position is provided on the back side of the panel 1, and the switch lock tongue 8 is assembled in the switch lock tongue 8 mounting position of the panel 1. An opening is provided on the side of the panel 1 for the switch lock tongue 8 to enter and exit. The switch lock tongue 8 moves linearly and enters and exits the mounting cavity to achieve the function of locking or unlocking; a slot hole 82 is provided on the switch lock tongue 8 perpendicular to the linear movement direction of the switch lock tongue 8, and the paddle on the outer handle 9 passes through the panel 1 and cooperates with the slot hole 82, and the paddle on the inner handle 10 passes through the back plate 3 and the base plate 2 and cooperates with the slot hole 82. By rotating the outer handle 9 or the inner handle 10, the corresponding paddle is controlled to toggle the switch lock tongue 8, thereby realizing the linear movement of the switch lock tongue 8 and controlling the switch state of the switch lock tongue 8.

[0030] The lock core 11 is installed on the outer handle 9, and a lock core 11 matching hole is opened on the panel 1. The lock core 11 is used to control the fixed or movable connection state of the outer handle 9 and the panel 1. When the lock core 11 is assembled in the lock core 11 matching hole and locked and fixed with the panel 1, the outer handle 9 and the panel 1 are locked and fixed; when the lock core 11 is opened and it is separated from the panel 1, the outer handle 9 is movably connected to the panel 1, and the outer handle 9 can rotate relative to the panel 1.

[0031] The inner handle 10 is rotatably connected to the back plate 3, specifically, it is hinged with an axial hole, so that the inner handle 10 can rotate relative to the back plate 3. The rotation of the inner handle 10 drives the paddle on the inner handle 10 to paddle the switch lock tongue 8, thereby realizing the linear movement of the switch lock tongue 8 and controlling the switch state of the switch lock tongue 8.

[0032] 2. Linkage structure of safety lock tongue 4

[0033] like Figure 2 , 3 As shown in Figures 5 and 6, an opening is provided on the side of the panel 1 for the safety lock tongue 4 to enter and exit.

When the lock tongue is subjected to external vibration, the compression spring 14 plays a buffering role, and the setting of the ball 15 will not hinder the linear movement of the lock tongue.

[0038] A plurality of positioning holes are arranged on the base plate 2 around the hole for installing the knob 7, and a straight hole 17 is arranged in the connecting sleeve 6. A compression spring 18 is mounted on the straight hole 17, and the other end of the compression spring 18 is connected to a ball 19. The ball 19 contacts the base plate 2. When the lock is subjected to external vibration, the compression spring 18 plays a buffering role. When the connecting sleeve 6 is rotated, the ball 19 rolls from one positioning hole of the base plate 2 to another positioning hole. After the ball 19 falls into the positioning hole, the angle of the connecting sleeve 6 after rotation will not change arbitrarily.

[0039] 4. Installation method of brake lock bolt 12.

[0040] like Figure 1 , 2As shown in FIG. 3 , a first slide groove 81 is provided on the side surface of the switch lock tongue 8 . The first slide groove 81 is in the shape of a right-angled triangular prism, and a right-angled surface is connected to the outside.

[0041] A second slide groove 41 is arranged on the side surface of the safety lock tongue 4. The second slide groove 41 is in the shape of a trapezoidal column, which is formed by connecting a rectangular parallelepiped and a right-angled triangular prism.

[0042] After the switch lock tongue 8 and the safety lock tongue 4 are assembled, the first slide groove 81 and the second slide groove 41 are arranged opposite to each other, and the two are spliced ​​to form a slide groove for the brake lock bolt 12 to slide.

[0043] The brake lock bolt 12 is block-shaped and is assembled in a slide groove formed by splicing the first slide groove 81 and the second slide groove 41 .

[0044] When the switch lock tongue 8 and the safety lock tongue 4 are both fully extended, the brake lock bolt 12 is at the triangular tip of the No. 2 slide groove 41, the retraction direction of the switch lock tongue 8 is blocked, and the switch lock tongue 8 cannot be retracted; when the safety lock tongue 4 is retracted, the brake lock bolt 12 is at the right-angle end of the No. 2 slide groove 41, the retraction direction of the switch lock tongue 8 is unobstructed, and the extended switch lock tongue 8 can be retracted; when the switch lock tongue 8 and the safety lock tongue 4 are both fully retracted, the brake lock bolt 12 is at the triangular tip of the No. 2 slide groove 41, the extension direction of the switch lock tongue 8 is unobstructed, and the switch lock tongue 8 can be extended.
