[0037] Reference Figures 1 to 9 In one embodiment of this utility model, a square shaft adapter for a lever lock body includes:
[0038] The columnar main body 110 is columnar and has a rectangular hole 111 extending through its thickness in the middle. The length of the rectangular hole 111 is 1.1 to 3.0 times its width.
[0039] The first side step portion 120 is annular and is disposed circumferentially at one end of the columnar portion body 110 in the thickness direction, while a first limiting portion 121 is formed at one end of the columnar portion body 110 in the thickness direction.
[0040] The second side step portion 130 is annular and is located circumferentially at the other end of the columnar main body 110 in the thickness direction, while the other end of the first limiting portion 121 in the thickness direction forms the second limiting portion 131;
[0041] A lever 140 is disposed on the peripheral wall of the columnar part body 110 and extends away from the columnar part body 110.
[0042] In this invention, the columnar main body 110 is columnar and has a rectangular hole 111 extending through its thickness in the middle. The columnar main body 110 mainly serves as the forming basis for the rectangular hole 111 and the lever 140, and is not limited to a cylindrical shape.
[0043] The length of the rectangular hole 111 is 1.1 to 3.0 times its width. A higher ratio improves adaptability but makes rotation of the columnar body 110 more difficult and increases its size. A lever 140 is located on the peripheral wall of the columnar body 110 and extends away from it. The lock body 200 requires a latch assembly 220 to operate. The lever 140 drives the latch assembly 220 when the square shaft adapter 100 rotates. The latch assembly 220 includes a latch 221, a sliding shaft 222, and a slider 223 connected in sequence. A mounting base 213 can be provided on the first cover 210. The sliding shaft 222 passes through the mounting base 213, and a coil spring 224 is sleeved on the sliding shaft 222 between the mounting base 213 and the latch 221. The lever 140 of the square shaft adapter 100 is set to correspond to the slider 223. When the square shaft adapter 100 rotates, the lever 140 drives the entire latch assembly 220 to slide through the slider 223. The square shaft 310 connected to the handle on the lever lock 300 passes through the rectangular hole 111, so that the rotation of the handle can drive the square shaft adapter 100 to rotate. The length of the rectangular hole 111 can be adapted to lever locks 300 within a certain model range, specifically to adapt to different spacings between the square shaft 310 and the lock cylinder assembly 250 on different lever locks 300.
[0044] The first side step portion 120 is provided circumferentially at one end of the columnar main body 110 in the thickness direction, and a first limiting portion 121 is formed at one end of the columnar main body 110 in the thickness direction; the second side step portion 130 is provided circumferentially at the other end of the columnar main body 110 in the thickness direction, and a second limiting portion 131 is formed at the other end of the first limiting portion 121 in the thickness direction. Taking the first limiting portion 121 as an example, a first accessory window 211 is provided at a corresponding position on the lock body 200, wherein the shape of the first accessory window 211 and the first limiting portion 121 is not limited to being the same; specifically, when the shapes are the same, the square shaft 310 and the rectangular hole 111 need to be in a clearance fit in their width direction to deal with the eccentricity, or a certain deformation is used to deal with the eccentricity (eccentricity between the square shaft 310 and the columnar main body 110); when the shape of the first accessory window 211 is larger than that of the first limiting portion 121, the first limiting portion 121 and the first accessory window 211 are in a clearance fit in the circumferential direction, thereby dealing with the eccentricity. It should be noted that, in actual operation, the angle that the square shaft adapter 100 needs to rotate through is relatively small.
[0045] In summary, the length of the rectangular hole 111 is 1.5 to 3 times its width. The square shaft 310 connected to the handle on the lever lock 300 passes through the rectangular hole 111, so that the rotation of the handle can drive the square shaft adapter 100 to rotate. The length of the rectangular hole 111 can be adapted to lever locks 300 within a certain model range, specifically to adapt to different spacings between the square shaft 310 and the lock cylinder assembly 250 on different lever locks 300.
[0046] Reference Figure 1 In one embodiment, the columnar body 110 is cylindrical.
[0047] In this embodiment, taking the first side step portion 120 as an example, it extends the entire circumference of the columnar main body 110. Therefore, a first limiting portion 121 with a small thickness is formed on the end face of the columnar main body 110. This first limiting portion 121 corresponds to the first accessory window 211 on the lock body 200 housing, thereby restricting the rotation of the square shaft adapter 100. This structure is advantageous for both processing and operation.
[0048] Reference Figure 1 In one embodiment, the square shaft adapter 100 further includes one or two limiting protrusions 150, the square shaft adapter being disposed on the peripheral wall of the columnar body 110 and extending away from the columnar body 110.
[0049] In this embodiment, the rotation angle of the square shaft adapter 100 is limited by the limiting protrusion 150. For example, a limiting post is provided at a relevant position on the lock body 200, which blocks the rotation of the square shaft adapter 100 by blocking the limiting protrusion 150. Thus, by setting the position of the limiting post or the limiting protrusion 150, the rotation angle of the square shaft adapter 100 can be set. Specifically, two limiting protrusions 150 can be provided, which can control the limiting of the rotation angle in two directions.
[0050] Reference Figure 2 In one embodiment, a filler plug 160 is detachably provided corresponding to the rectangular hole 111.
[0051] In this embodiment, after the square shaft 310 passes through the rectangular hole 111, the filler plug 160 can fill the gap formed between them, thus improving the fixing effect of the square shaft 310, and consequently improving the fixing effect of the lever lock 300. Specifically, the filler plug 160 can be made of plastic or rubber, etc.
[0052] Reference Figure 2 In one embodiment, the rectangular hole 111 has a toothed structure 112 arranged on its inner wall along its length.
[0053] In this embodiment, the toothed structure 112 enhances the fixing effect of the filler plug 160, reducing the possibility of loosening or abnormal noise. The elastic deformation of the toothed structure 112 and its high coefficient of friction interface create a better fixing effect. Simultaneously, the toothed structure 112 can also handle eccentric situations.
[0054] In one embodiment, the columnar body 110 is cylindrical, and the rectangular hole 111 passes through the axis of the columnar body 110. The length of the rectangular hole 111 is 1.5 to 3 times its width.
[0055] In this embodiment, the columnar main body 110 has a symmetrical shape, which improves stability during rotation. The aspect ratio of the rectangular hole 111 achieves a balance between adaptability and the structural rationality of the columnar main body 110.
[0056] Reference Figure 2 In one embodiment, the middle part of the rectangular hole 111 along its length is the center of the columnar body 110.
[0057] In some embodiments, one end of the rectangular hole 111 in the length direction can start from the center of the columnar body 110. In this embodiment, the middle part of the rectangular hole 111 in the length direction is the center of the columnar body 110. Therefore, the length dimension of the rectangular hole 111 can be shortened or adapted to a wider range.
[0058] Reference Figures 5 to 7 In one embodiment of this utility model, a lock body includes the aforementioned square shaft adapter 100, and the lock body 200 further includes:
[0059] The first cover 210 is provided with a first accessory window 211 and a first gourd hole 212;
[0060] The oblique tongue assembly 220 is movably disposed on the first cover 210 and corresponds to the lever 140 of the square shaft adapter 100;
[0061] The second cover 230 is detachably connected to the first cover 210. The second cover 230 is provided with a second accessory window 231 and a second gourd hole 232 corresponding to the first accessory window 211 and the first gourd hole 212. The first limiting part 121 and the second limiting part 131 of the square shaft adapter 100 are respectively provided in the first accessory window 211 and the second accessory window 231.
[0062] The square tongue component 240 is movably disposed on the first cover 210 corresponding to the second gourd hole 232.
[0063] In this embodiment, the lock body 200, which includes the square shaft adapter 100, can be adapted to more than one type of lever handle lock 300. The combination of the first cover 210 and the second cover 230 forms the main structure of the lock body 200. This main structure is located in the middle of the door leaf thickness direction. Correspondingly, a lock bar 250 can also be provided on the main structure, which is located on the side of the door leaf. The first accessory window 211 on the first cover 210 and the second accessory window 231 on the second cover 230 are used to limit the abnormal displacement of the square shaft adapter 100.
[0064] The latch assembly 220 includes a latch 221, a sliding shaft 222, and a slider 223 connected in sequence. A mounting base 213 can be provided on the first cover 210. The sliding shaft 222 passes through the mounting base 213, and a helical spring 224 is sleeved on the sliding shaft 222 between the mounting base 213 and the latch 221. The lever 140 of the square shaft adapter 100 is set corresponding to the slider 223. When the square shaft adapter 100 rotates, the lever 140 drives the entire latch assembly 220 to slide through the slider 223. Corresponding through-slot structures can be provided on the first cover 210 and the second cover 230 to guide the sliding of the slider 223. The first gourd hole 212 on the first cover 210 and the second gourd hole 232 on the second cover 230 are used to restrict the lock cylinder assembly 250. The driving method of the lock cylinder assembly 250 and the square latch assembly 240 follows the existing conventional settings and is not the focus. For example, a square tooth drive can be used, and the control of the square tongue assembly 240 can be achieved by rotating the relevant components on the lock cylinder assembly 250.
[0065] Reference Figure 8 In one embodiment, the first accessory window 211 and the second accessory window 231 are provided with a first handle lock hole group on both sides of the lock body 200 in the width direction. The first handle lock hole group includes at least two first handle lock holes 260 that are spaced apart in the length direction of the lock body 200.
[0066] In this embodiment, different models of lever handle locks 300 are adapted by first lever handle lock holes 260 spaced apart along the length of the lock body 200. For example, if two first lever handle lock holes 260 are spaced 8 mm apart, they can be adapted to models 50 and 58 lever handle locks 300 respectively.
[0067] Reference Figure 9 In one embodiment, the first accessory window 211 and the second accessory window 231 are provided with second handle lock holes 270 on both sides of the width direction of the lock body 200. The second handle lock holes 270 are oblong holes and their length direction is consistent with the length direction of the lock body 200.
[0068] In this embodiment, by setting the second handle lock hole 270 as an oblong hole, different models of handle locks 300 can be adapted through the characteristics of the oblong hole.
[0069] In summary, the square shaft adapter and lock body of the lever lock provided by this utility model have a rectangular hole 111 whose length is 1.5 to 3 times its width. The square shaft 310 connected to the handle on the lever lock 300 passes through the rectangular hole 111, so that the rotation of the handle can drive the square shaft adapter 100 to rotate. The length of the rectangular hole 111 can be adapted to lever locks 300 within a certain model range, specifically to adapt to different spacings between the square shaft 310 and the lock cylinder assembly 250 on different lever locks 300.
