[0044] In order to enable those skilled in the art to better understand the present utility model and thus more clearly define the scope of protection required by the present utility model, the present utility model will be described in detail below with respect to certain specific embodiments of the present utility model. It should be noted that the following are only some specific embodiments of the concept of the present utility model, and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and each specific feature does not of course and directly limit the scope of implementation of the present utility model. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model shall be regarded as being within the scope of protection required by the present utility model.

[0045] As Figures 1 - 10 shown, the present utility model discloses a safety lock, which includes a locking base 1, a mounting base 2 and a locking belt 3. The locking belt 3 is used to connect the locking base 1 and the mounting base 2. Among them, the mounting base 2 and the locking base 1 are respectively mounted on the product to be locked. For example, when applied to a refrigerator, the locking base 1 is mounted on the refrigerator door, and the mounting base 2 is mounted on the side wall of the refrigerator. When applied to a drawer, the locking base 1 is mounted on the drawer box, and the mounting base 2 is mounted on the table, so that when the locking base 1 is self-locked, the product is locked, and when the locking base 1 is unlocked, the product is unlocked.

[0046] Among them, the locking base 1 includes a first locking member 11 and a second locking member 12 that are detachably connected. The first locking member 11 is at the rear and the second locking member 12 is at the front. Specifically, a first fixing surface is provided on the bottom surface at the rear side of the first locking member 11, and the first locking member 11 is attached to the refrigerator or drawer through the first fixing surface. Two protruding protrusions 111 are provided on the front side of the first locking member 11, and plugging grooves 112 are provided on the protruding protrusions 111 in the left and right directions. Correspondingly, the second locking member 12 includes a seat portion 121 and a sliding cover 122. The sliding cover 122 slides on the seat portion 121 in the left and right directions, and a plugging convex portion 1221 is provided on the sliding cover 122. In addition, the left end of the locking belt 3 is connected to the second locking member 12 by a clamping method.

[0047] Therefore, in the state where the first lock body and the second lock body are separated, the second lock member 12 moves backward towards the first lock member 11, and the protruding projection 111 is inserted into the seat portion 121. Then, the sliding cover 122 slides to the right so that the plugging convex portion 1221 is inserted into the plugging groove 112 to achieve the fixed connection between the first lock member 11 and the second lock member 12, that is, to lock. In the state where the first lock body and the second lock body are connected, the sliding cover 122 slides to the left so that the plugging convex portion 1221 is disengaged from the plugging groove 112, and then the second lock member 12 moves forward to separate from the first lock body, that is, to unlock.

[0048] In addition, a compression spring (not shown in the figure) is provided between the seat portion 121 and the sliding cover 122, so that the compression spring resets the sliding cover 122 to the right to stably insert the plugging convex portion 1221 into the plugging groove 112.

[0049] In addition, for the specific structure of the locking seat 1, reference can be made to Chinese Patent No. CN202322196137.6.

[0050] Among them, the mounting seat 2 includes a mounting member 21 and an opening / closing member 22. The mounting member 21 is at the rear and the opening / closing member 22 is at the front. Specifically, the opening / closing member 22 is rotatably mounted on the mounting member 21, and a cavity 216 is formed in cooperation with the two. In addition, the locking belt 3 is inserted into the cavity 216. In addition, a first clamping portion 31 is provided on the rear side of the locking belt 3, and a second clamping portion 211 that is clamped and matched with the first clamping portion 31 is provided on the mounting member 21 in the cavity 216. And a first pressing member 221 and a second pressing member 224 are provided on the opening / closing member 22. When the opening / closing member 22 rotates to the position where the first pressing member 221 faces the locking belt 3, the first pressing member 221 presses the locking belt 3 so that the first clamping portion 31 and the second clamping portion 211 are in concave-convex cooperation to lock and connect the locking belt 3 with the mounting seat 2. Specifically, the first pressing member 221 can directly contact and press on the locking belt 3, or there is a small distance between the first pressing member 221 and the locking belt 3, and the locking belt 3 can move within this distance, but cannot cause the first clamping portion 31 and the second clamping portion 211 to separate under the pressing of the first pressing member 221. When the opening / closing member 22 rotates to the position where the second pressing member 224 faces the locking belt 3, the first clamping portion 31 and the second clamping portion 211 are separated to make the locking belt 3 detachably connected to the mounting seat 2.

[0051] Therefore, 1. When installing the mounting seat 2 and the locking belt 3, it is only necessary to first insert the locking belt 3 from left to right into the mounting member 21, and then move it backward so that the first engaging portion 31 and the second engaging portion 211 cooperate, so that after insertion, the mounting member 21 and the locking belt 3 have a certain degree of left - right sliding restriction under the cooperation of the first engaging portion 31 and the second engaging portion 211. Then, by rotating the opening - closing member 22 to make the first abutting member 221 rotate to the front side of the locking belt 3 to clamp the locking belt 3 front - and - back, the locking belt 3 cannot move forward, thus ensuring the stable clamping cooperation of the first engaging portion 31 and the second engaging portion 211, so as to ensure the stability of the installation of the mounting seat 2 and the locking belt 3. On the contrary, when disassembling the mounting seat 2 and the locking belt 3, by rotating the opening - closing member 22 to make the second abutting member 224 rotate to the front side of the locking belt 3, there is a certain distance between the second abutting member 224 and the locking belt 3, which allows the locking belt 3 to move forward to achieve the disengagement of the first engaging portion 31 and the second engaging portion 211, so that the locking belt 3 can be pulled out from the belt cavity 216 to the left to complete the disassembly. 2. When disassembling and assembling the locking belt 3, there is no need to disassemble the mounting member 21 and the opening - closing member 22. The mounting seat 2 is disassembled and assembled with the locking belt 3 as a whole, making the installation more convenient and preventing the loss of components of the mounting member 21 and the opening - closing member 22 during the disassembly and assembly of the mounting seat 2.

[0052] Among them, an insertion hole 215 that penetrates from the outside to the inside and communicates with the belt cavity 216 is provided on the left side of the mounting member 21. The thickness of the insertion hole 215 is h1, and the thickness of the locking belt is h2, where h1 > h2. This allows the operator to drive the locking belt 3 forward outside the mounting seat 2, and utilize the height difference between the insertion hole 215 and the locking belt 3 to achieve the cooperation or disengagement of the first engaging portion 31 and the second engaging portion 211.

[0053] In other embodiments, the first abutting member 221 and the second abutting member 224 are provided on the mounting member 21, and the second engaging portion 211 is provided on the opening - closing member 22, so that the rotation of the opening - closing member 22 drives the locking belt 3 to rotate together. In comparison, in this embodiment, after the mounting member 21 is installed, rotating the opening - closing member 22 does not drive the locking belt 3, making the operation smoother.

[0054] Among them, the first engaging portion 31 is a plurality of teeth or tooth grooves arranged in the left - right direction at the rear side; correspondingly, the second engaging portion 211 is at least one arranged tooth or tooth groove. Specifically, in this embodiment, the first engaging portion 31 is a plurality of arranged tooth grooves, and the second engaging portion 211 is two teeth arranged left - right. This makes the locking belt 3 in the clamped state more stable due to the cooperation of the teeth, with the rear side being clamped by the mounting member 21 and the front side being clamped by the opening - closing member 22. In addition, if it is necessary to cut the locking belt 3 to a shorter length, due to the setting of the plurality of first engaging portions 31, the locking belt 3 still has the first engaging portion 31 after being cut to ensure that it can be engaged with the second engaging portion 211.

[0055] Among them, the rotation angle range of the opening and closing member 22 is α. Preferably, 5° ≤ α ≤ 175°.

[0056] Preferably, in this embodiment, the outer perimeters of the mounting member 21 and the opening and closing member 22 are quasi-square. The mounting member 21 and the opening and closing member 22 cooperate to have a locked state and an unlocked state. Among them, Figure 1 、 Figure 6 is the locked state, Figure 3 、 Figure 7 is the unlocked state. The rotation angle of the opening and closing member 22 from the locked state to the unlocked state is α, and 75° ≤ α ≤ 85°.

[0057] Therefore, 1. When the mounting member 21 and the opening and closing member 22 are in the locked state, the outer perimeters of the mounting member 21 and the opening and closing member 22 overlap in the front-back direction, which is not only more concise and beautiful, but also the opening and closing member 22 is more stable and not easily rotated by external interference. 2. When the mounting member 21 and the opening and closing member 22 are in the unlocked state, the outer perimeters of the mounting member 21 and the opening and closing member 22 do not overlap in the front-back direction, making the mounting member 21 and the opening and closing member 22 have obvious differences visually and tactilely, so as to better judge the state of the opening and closing member 22 and better control the rotation of the opening and closing member 22. 3. The rotation angle α for state conversion is close to 90°, so that it only switches between two sides of the quadrilateral. Not only does the outer perimeter of the mounting member 21 and the outer perimeter of the opening and closing member 22 overlap in the front-back direction only in the locked state, making the locked state uniquely and accurately confirmed, but also the angle is larger under the above limitation to increase the rotation stroke to prevent the locked state and the unlocked state from switching randomly.

[0058] Among them, the quasi-square structure is a structure with four sides. The four sides of the quasi-square structure can be straight edges, or arc edges, or a combined square structure of straight edges and arc edges. The connection between adjacent two sides is smoothly connected by an arc. And the quasi-square structures here are all structures observed from the front view of the mounting member 21 and the opening and closing member 22.

[0059] In other embodiments, 90 < α < 180 or 180 < α < 270 or 270 < α < 360, so that there are also differences between the locked state and the unlocked state for easy identification.

[0060] In addition to the outer peripheries of the above-mentioned mounting member 21 and opening / closing member 22 being quasi-square, in other embodiments, the outer peripheries of the mounting member 21 and the opening / closing member 22 are quasi-regular polygons with N sides, where N ≥ 3, N ≠ 4, and N is a positive integer. Commonly, they are triangles and hexagons. Among them, the mounting member 21 and the opening / closing member 22 cooperate to have a locked state and an unlocked state. The rotation angle of the opening / closing member 22 from the locked state to the unlocked state is α, where 0 < α < 360 / N or 360 / N < α < 720 / N or 720 / N < α < 1080 / N. In such shapes, the characteristics similar to those of the above-mentioned quasi-square are also possessed.

[0061] Specifically, in this embodiment, a circular connection part 222 is integrally formed at the rear side of the opening / closing member 22. An arc-shaped rotation track 2221 is provided on the outer periphery of the connection part 222. Correspondingly, an inner groove 212 adapted to the connection part 222 is formed on the front side of the mounting member 21, and a rotation part 2121 that cooperates with the rotation track 2221 protrudes from the peripheral wall of the inner groove 212.

[0062] Therefore, the connection part 222 realizes radial rotation limitation by being placed in the inner groove 212, and then realizes front-back direction limitation through the cooperation of the rotation part 2121 and the rotation track 2221, so that the opening / closing member 22 can rotate relative to the mounting member 21.

[0063] Specifically, the rotation part 2121 is inserted into the rotation track 2221 from the outer periphery of the connection part 222.

[0064] Among them, a disassembly / assembly opening 2222 is provided at the rear side of the connection part 222 where the rotation track 2221 is located. In a state where the disassembly / assembly opening 2222 and the rotation part 2121 are aligned front and back, the mounting member 21 and the opening / closing member 22 approach each other front and back so that the rotation part 2121 enters the rotation track 2221 through the disassembly / assembly opening 2222. At this time, the opening / closing member 22 and the mounting member 21 are in an unlocked state, and then the rotation part 2121 and the disassembly / assembly opening 2222 are circumferentially misaligned by the rotation of the opening / closing member 22.

[0065] In addition, a first positioning part 2223 in the shape of an isosceles trapezoid protrudes from the inner wall of the rotation track 2221 in this embodiment. Correspondingly, a second positioning part 2122 that is inserted into the rotation track 2221 from the outer periphery of the connection part 222 is provided on the mounting member 21. And when the opening / closing member 22 and the mounting member 21 cooperate to be in a locked state, the first positioning part 2223 and the second positioning part 2122 cooperate to limit the rotation of the opening / closing member 22, so as to further improve the connection stability between the mounting seat 2 and the lock belt 3 in the locked state.

[0066] Specifically, a clamping groove 2123 adapted to the shape of the first positioning portion 2223 is formed in the second positioning portion 2122. When the opening and closing member 22 moves from the unlocked state to the locked state, the first positioning portion 2223 crosses the outer wall of the second positioning portion 2122 and is clamped in the clamping groove 2123 to achieve mating positioning. When the opening and closing member 22 moves from the locked state to the unlocked state, the first positioning portion 2223 moves out of the clamping groove 2123 and disengages from the second positioning portion 2122 to release the mating.

[0067] In addition, a first guiding inclined surface 2224 is provided on the outer periphery at the rear side of the connecting portion 222, and a second guiding inclined surface 2124 is provided on the front side of the second positioning portion 2122; and a deformable portion 2125 in the shape of a thin plate is provided between the second positioning portion 2122 and the mounting member 21, such that the rear side of the deformable portion 2125 is integrally formed and connected to the mounting member 21, and the front side of the deformable portion 2125 is integrally formed and connected to the second positioning portion 2122. Therefore, when the mounting member 21 and the opening and closing member 22 approach each other front and rear, under the action of the first guiding inclined surface 2224 and the second guiding inclined surface 2124, the deformable portion 2125 deforms to drive the second positioning portion 2122 to smoothly enter the rotation track 2221. When the second positioning portion 2122 is in clamping fit with the rotation track 2221, it can limit the front and rear movement of the mounting member 21 and the opening and closing member 22 to prevent them from separating from each other, having an anti-disassembly function. In addition, the second positioning portion 2122 can also rotate relative to the rotation track 2221 to cooperate with the first positioning portion 2223 to make the locked state more stable.

[0068] Preferably, the number of the rotation tracks 2221, the rotation portions 2121, the first positioning portions 2223, and the second positioning portions 2122 is two, so as to improve the stability through two sets of cooperation.

[0069] In addition, the first abutting member 221 in this embodiment includes a main pressing portion 2211 provided on the inner circumference of the connecting portion 222 and an auxiliary pressing portion 2212 provided on the rear side of the connecting portion 222; the auxiliary pressing portion 2212 is arc-shaped, and an unlocking groove 2213 is provided between the head and the tail of the arc-shaped auxiliary pressing portion 2212, and the second abutting member 224 is provided in the unlocking groove 2213, such that the first abutting member 221 protrudes backward from the second abutting member 224 and the first abutting member 221 is higher than the second abutting member 224. In the locked state, both the main pressing portion 2211 and the auxiliary pressing portion 2212 are located in front of the locking belt 3 to limit the upward movement of the locking belt 3. During the rotation from the locked state to the unlocked state, the main pressing portion 2211 first rotates away from the front side of the locking belt 3 to partially release the forward restriction of the locking belt 3, and when rotating to the unlocked state, the auxiliary pressing portion 2212 rotates away from the front side of the locking belt 3 to completely release the forward restriction of the locking belt 3. At this time, when the second abutting member 224 is located in front of the locking belt 3, due to the existence of the space in the unlocking groove 2213, the locking belt 3 can enter the unlocking groove 2213 forward to disengage the first engaging portion 31 and the second engaging portion 211.

[0070] In addition, the auxiliary pressing portion 2212 and the second resisting member 224 are inclined to form a smoother inclined surface shape. In other embodiments, a vertical surface can be set between the auxiliary pressing portion 2212 and the second resisting member 224 to form a step shape.

[0071] In addition, a stroke limiting groove 213 is provided on the front side of the mounting member 21 in this embodiment, and a stroke limiting member 223 extending into the stroke limiting groove 213 is provided on the rear side of the opening and closing member 22. The stroke limiting member 223 rotates in the stroke limiting groove 213 and is positioned in a locked state and an unlocked state under the action of the surrounding wall of the stroke limiting groove 213, making the positioning operation more convenient and accurate.

[0072] In addition, a rotating base 23 is provided on the rear side of the mounting member 21 in this embodiment, and a second fixed surface is provided on the rear bottom surface of the rotating base 23. The mounting base 2 is attached to the refrigerator or drawer through the second fixed surface, so that the mounting member 21 can be rotated relative to the rotating base 23, so that when there is no need to lock the refrigerator or drawer, the lock belt 3 can be suspended as the mounting member 21 rotates, thereby preventing the lock belt 3 from affecting the use of the refrigerator or drawer, and the appearance is more beautiful.

[0073] Specifically, a rotating through hole 214 is provided on the mounting member 21, and a rotating plug 231 is provided on the rotating base 23, so that the rotating base 23 can be rotated to cooperate with the mounting member 21 by inserting the rotating plug 231 into the rotating through hole 214, and then the rotating plug 231 is installed by the mounting bolt 24 to prevent the rotating plug 231 from falling out of the rotating through hole 214, thereby ensuring the stability of the installation.

[0074] In other embodiments, a third stopper is further provided on the opening and closing member 22, and the third stopper and the first stopper 221 are at the same height, and the first stopper 221, the second stopper 224 and the third stopper are arranged in sequence along the circumferential direction, wherein the first stopper 221, the second stopper 224 and the third stopper can all be rotated to align with the lock belt 3, so that when the opening and closing member 22 is rotated until the third stopper is aligned with the lock belt 3, the third stopper and the first stopper 221 have the same effect, and the lock belt 3 can be pressed to lock and connect the lock belt 3 with the mounting seat 2 through the concave-convex cooperation of the first clamping portion 31 and the second clamping portion 211, so that the lock belt 3 can be removed only when the second stopper 224 and the lock belt 3 are aligned, so that the lock belt 3 cannot be removed at both ends of the rotation of the opening and closing member 2, which has a better protection effect on children. Specifically, the third abutment can be directly pressed onto the lock band 3, or a small distance can be maintained between the third abutment and the lock band 3, and the lock band 3 can move within the distance, but the first clamping portion 31 and the second clamping portion 211 cannot be separated from each other due to the pressing of the third abutment.
