Technical Field

[0001] The present invention relates to a handle linkage mechanism, and in particular to a self-locking module device. Background Art

[0002] Currently, the mainstream module fixing structures on the market can be divided into two types. One is fixed by bolts. For example, in the utility model patent case with the Chinese publication number CN209435196U and the patent name "An LC Filter Compensation Module Group", the patented technology discloses a module group, which includes a housing body. A handle is provided at the upper end of the outer surface of the housing body. Five first fixing bolts are provided on one side of the outer surface of the housing body. The utility model fixes the side covers on both sides of the housing body, and the side covers and the housing body are fixedly connected through the first fixing bolts. The module group is mainly disassembled and assembled by bolts, and the handle only serves the function of allowing the user to carry the module group.

[0003] The other is fixed by buckles. For example, in the utility model patent case with the Chinese publication number CN212399514U and the patent name "A Portable Trolley for a Modular Toolbox", the patented technology discloses a modular toolbox, which includes a box body, a box cover and a handle. At least one front displacement female buckle is provided on the front side of the box cover; at least one buckle matching device is provided on the front side of the box body. The buckle matching device and the front displacement female buckle on the box cover are in corresponding up and down positions and cooperate with each other. The modular toolbox is mainly disassembled and assembled by a buckle device. The handle only serves for the user to apply force to separate the box cover and the box body, and the handle has no direct relation with the fixation of the modular toolbox.

[0004] It is true that the structures of the above two can both fix the box body. However, for the user, when separating the cover body and the box body, tools are needed to remove the bolts or disassemble the buckle device, and it cannot be separated quickly; when combining the cover body and the box body, tools are needed to tighten the bolts or fasten the buckle device, and it cannot be automatically locked. Thus, the convenience of disassembling and assembling the module group or the modular toolbox is greatly reduced. Therefore, how to provide a module device that can be automatically locked and can be quickly separated is an urgent problem to be solved at present. Summary of the Invention

[0069] To more clearly illustrate the present invention, preferred embodiments are cited below and described in detail in conjunction with the accompanying drawings. Please refer to Figure 1 and Figure 2 As shown, the self-locking module device 100 of the first preferred embodiment of the present invention includes a box body 10, a module base 20, and a rotary linkage structure 30. The module base 20 is detachably combined with the box body 10. The box body 10 and the module base 20 are used for installing electronic modules or mechanical modules thereon. When the module base 20 is pushed into the box body 10 for combination, the module base 20 is automatically locked to the box body 10 through the rotary linkage structure 30.

[0070] The box body 10 includes a bottom plate 12, a top plate 14, and two side plates 16. The bottom plate 12, the top plate 14, and the two side plates 16 surround to form a module space 18 and an access port 181 leading to the module space 18. The two side plates 16 respectively have two locking holes 161, and the two locking holes 161 of each side plate 16 are located near the access port 181. In other embodiments, each side plate 16 may also be provided with only one locking hole 161.

[0071] Please refer to Figure 3As shown, the module base 20 includes a cover 22, a bottom frame 24, and a plurality of elastic sheet groups 26. The lower end of the cover 22 is connected to the bottom frame 24. When the module base 20 is combined with the box body 10, the cover 22 is embedded in the placement opening 181 and the bottom frame 24 abuts against the bottom plate 12. The cover 22 includes a cover plate 221, a top frame 222, and two side frames 223. The cover plate 221 closes the placement opening 181, and the two sides of the cover plate 221 facing and departing from the module space 18 are divided into the inner side and the outer side. The periphery of the cover plate 221 also has upper and lower sides and left and right sides. The cover plate 221 has a through portion 2211. The left and right sides of the cover plate 221 are connected to the respective side frames 223. Each side frame 223 has two through holes 223a. In this embodiment, the bottom frame 24 is a tray. When the module base 20 is combined with the box body 10, the tray extends into the bottom side of the module space 18. In addition, the through portion 2211 is provided in the middle of the cover plate 221.

[0072] When the module base 20 is combined with the box body 10, the two side frames 223 respectively abut against the respective side plates 16, and the two through holes 223a of each side frame 223 are aligned with the two locking holes 161 of the respective side plates 16. The bottom parts of the two side frames 223 and the bottom frame 24 are respectively provided with the respective elastic sheet groups 26. When the module base 20 is combined with the box body 10, each side frame 223 abuts against the respective side plates 16 through the respective elastic sheet groups 26, and the bottom frame 24 is positioned by abutting against the bottom plate 12 through the elastic sheet groups 26. In other embodiments, in accordance with the number of locking holes 161 provided on the respective side plates 16, the corresponding number of through holes 223a are provided on each side frame 223, and when the module base 20 is combined with the box body 10, each through hole 223a of each side frame 223 corresponds to each locking hole 161 of the respective side plates 16.

[0073] The rotary linkage structure 30 is installed on the cover 22 and includes a rotary disk 32, a rotary handle 34, two locking bolts 36, and at least one spring 38; the rotary disk 32 has a rotary center portion 321 and two insertion rods 33 are combined around the rotary center portion 321. In this embodiment, the left and right ends of the rotary disk 32 are respectively combined with the respective insertion rods 33. The rotary disk 32 is arranged on the inner side of the cover plate 221 and is rotatably arranged in the through portion 2211 with the rotary center portion 321. A part of the rotary handle 34 passes through the through portion 2211 and is combined with the rotary disk 32. Specifically, as Figure 7 and Figure 8As shown, in this first preferred embodiment, the rotating disk 32 is cross-shaped, and the turning handle 34 is a handle 341 with two ends. A non-circular hole 2211c is provided at the middle position of the insertion portion 2211, and a first hole 2211a and a second hole 2211b are respectively provided at the upper and lower ends on the opposite sides around the insertion portion 2211. The first hole 2211a and the second hole 2211b are respectively arc-shaped holes centered on the non-circular hole 2211c.

[0074] The cover body 22 further includes an axis fixing seat 224, and the axis fixing seat 224 is fixedly connected to the non-circular hole 2211c. The rotation center portion 321 of the rotating disk 32 is a shaft hole and is sleeved on the axis fixing seat 224, so that the rotating disk 32 can rotate relative to the axis fixing seat 224. The two ends of the handle 341 respectively pass through the first hole 2211a and the second hole 2211b and are fixedly connected to the upper and lower ends around the rotating disk 32; the first hole 2211a and the second hole 2211b allow the handle 341 passing through them to rotate reciprocally relative to the insertion portion 2211.

[0075] The two locking bolts 36 are arranged inside the cover plate 221. The two locking bolts 36 are respectively located on both sides of the rotating disk 32 and respectively correspond to one of the insertion rods 33. A track device 35 is respectively formed between each locking bolt 36 and the cover plate 221, so that each locking bolt 36 can reciprocally move in a straight line direction. Specifically, each locking bolt 36 reciprocally moves between a first position P1 and a second position P2 along the track device 35; the outer end of each locking bolt 36 is provided with a corresponding number of locking tongues 361 according to the number of locking holes 161 provided on each side plate 16. In this preferred embodiment, the outer end of each locking bolt 36 has two locking tongues 361. Each locking tongue 361 extends out around the cover plate 221 and is inserted into each locking hole 161. Specifically, the two locking tongues 361 of each locking bolt 36 pass through the two through holes 223a of each side frame 223 and are inserted into the two locking holes 161 of each side plate 16 for positioning.

[0076] The inner end of each latch 36 includes a displacement hole 362. Each insertion rod 33 passes through each displacement hole 362. The displacement hole 362 is an arc-shaped hole and has a first end 362a and a second end 362b. Each insertion rod 33 is located at the first end 362a. The first end 362a is at a first length L1 from the center of the rotation center portion 321. The second end 362b is at a second length L2 from the center of the rotation center portion 321. The second length L2 is greater than the first length L1. When the latch 36 is at the first position P1, the two locking tongues 361 protrude from the two perforations 223a of the side frame 223 and are inserted into the two locking holes 161. Each of the above track devices 35 has a track hole 363 and two fixing members 226. Each track hole 363 is provided on each latch 36. The two fixing members 226 pass through each track hole 363 and are fixed to the cover plate 221, so that the track hole 363 of each latch 36 can slide linearly along the two fixing members 226.

[0077] In this embodiment, the at least one spring 38 is one. The spring 38 is a torsion spring. The spring 38 has a main body portion 381, and the main body portion 381 is disposed in a notch 224a of the shaft center fixing seat 224. The spring 38 has two ends for respectively hooking on each insertion rod 33. Therefore, the spring 38 is used to drive each insertion rod 33 to tend to move along each displacement hole 362 towards the first end 362a.

[0078] As Figure 5 and Figure 6 As shown, the part of each locking tongue 361 protruding from the perforation 223a has an inclined surface 361a. When the user wants to combine the module seat 20 with the box body 10, the module seat 20 is brought close to the module space 18. Each inclined surface 361a abuts against the side plate 16. The side plate 16 gives the two latches 36 a force to move towards the second position P2 through each inclined surface 361a. Each inclined surface 361a is pressed by each side plate 16 to retract each locking tongue 361 into each perforation 223a. At this time, the two latches 36 also retract and displace to the second position P2. Then the module seat 20 continues to be pushed towards the box body 10. When each perforation 223a is aligned with each locking hole 161, due to the restoring force of the spring 38 pushing each insertion rod 33, each insertion rod 33 moves along each displacement hole 362 towards the first end 362a, driving each latch 36 to return to the first position P1. At this time, each locking tongue 361 and its inclined surface 361a protrude from each perforation 223a and are inserted into each locking hole 161, and the module seat 20 and the box body 10 complete automatic locking.

[0079] When the user rotates the handle 341, the inner rotating disk 32 also rotates relative to the axis fixing base 224 accordingly. The two inserting rods 33 provided on both sides of the rotating disk 32 respectively move from the first end 362a of the displacement hole 362 to the second end 362b of the displacement hole 362, driving the two locking bolts 36 to move along the respective rail devices 35 from the first position P1 to the retracted position of the second position P2, and each inserting rod 33 presses on each end of the spring 38. During the retraction process of each locking bolt 36, the two locking tongues 361 of each locking bolt 36 sequentially move out of the two locking holes 161 of each side plate 16 and the two through holes 223a of the side frame 223, so that the locking between the module base 20 and the box body 10 is released, and the module base 20 can be pulled out relative to the box body 10. When the module base 20 is pulled out of the box body 10 and the user no longer applies force to the handle 341, the spring 38 has a restoring force to move the two inserting rods 33 from the second end 362b to the first end 362a, so that the two locking bolts 36 located on both sides of the rotating disk 32 respectively move along the respective rail devices 35 from the second position P2 to the first position P1 to return to their original positions. At this time, the two locking tongues 361 of each locking bolt 36 extend out of the two through holes 223a of the side frame 223.

[0080] In addition to the above first preferred embodiment of the present invention, where the rotation linkage structure 30 is provided with the two locking bolts 36 on opposite sides, in other preferred embodiments, only one locking bolt 36 may be provided on one side of the left and right sides of the rotation linkage structure 30. At this time, only the through hole 223a is provided on the side frame 223 corresponding to the side of the locking bolt 36, only the locking hole 161 is provided on the side plate 16 corresponding to the side of the locking bolt 36, and only one inserting rod 33 corresponding to the displacement hole 362 of the locking bolt 36 is provided at the rotation center portion 321 and inserted into the displacement hole 362. Such a change can also achieve the function of automatically locking the module base 20 into the box body 10, or releasing the locking between the module base 20 and the box body 10 and pulling the module base 20 out of the box body 10.

[0081] Please refer to Figure 9 and Figure 10The second preferred embodiment shown. In this second preferred embodiment, different from the first preferred embodiment, there are two of the at least one spring 38, and the two springs 38 are tension springs. In this embodiment, the two springs 38 are located on the left and right sides of the rotating disk 32. One end of one spring 38 is hooked to one of the inserting rods 33, and the other end is set on the latch 36 on the corresponding side of the inserting rod 33; one end of the other spring 38 is hooked to the other inserting rod 33, and the other end is set on the other latch 36 on the corresponding side of the other inserting rod 33. When the user rotates the handle 341, the rotating disk 32 located inside also rotates relative to the axis fixing seat 224 accordingly. The two inserting rods 33 provided on both sides of the rotating disk 32 respectively move from the first end 362a of the displacement hole 362 to the second end 362b of the displacement hole 362, and the lengths of the two springs 38 also increase accordingly. At this time, the two springs 38 are in a tension state. When the user no longer applies force to the handle 341, each spring 38 has a restoring force that can be used to drive the rotating disk 32 and its inserting rod 33 to reset, so that each inserting rod 33 moves from the second end 362b of each displacement hole 362 to the first end 362a of the displacement hole 362.

[0082] Please refer to as Figure 11 and Figure 12 The third preferred embodiment shown. In this third preferred embodiment, different from the second preferred embodiment, each of the springs 38 has two ends, and one end is hooked to each of the inserting rods 33, and the other end is fixedly set on the surface of the cover plate 221. When the user rotates the handle 341, the two springs 38 can also produce the same reset effect as in the second preferred embodiment.

[0083] Please refer to as Figure 13 and Figure 14The fourth preferred embodiment shown. In this fourth preferred embodiment, different from the first preferred embodiment, the rotary disk 32 is in a linear shape, wherein the handle 34 is a knob 342, and the cover body 22 further includes an axial center connecting member 225. The axial center connecting member 225 is rotatably pivotally penetrated through the center of the penetrating portion 2211 in a state of a shaft hole. The axial center connecting member 225 has two ends, with one end fixedly connected to the knob 342 and the other end fixedly connected to the rotary center portion 321. The axial center connecting member 225 can rotate relative to the cover plate 221. The two springs 38 are combined on the left and right opposite sides around the rotary disk 32. The at least one spring 38 is two. The two springs 38 are tension springs. One end of each spring 38 is hooked on each of the inserting rods 33, and the other end of each spring 38 is arranged on each of the latches 36. When the user rotates the knob 342, it drives the axial center connecting member 225 to rotate relative to the cover plate 221, and the rotary disk 32 also rotates accordingly. The two inserting rods 33 arranged on the left and right sides of the rotary disk 32 respectively move from the first end 362a of the displacement hole 362 to the second end 362b of the displacement hole 362, while stretching the lengths of the two springs 38. When the user no longer applies force to the handle 341, each spring 38 has a restoring force applied to each inserting rod 33, causing each inserting rod 33 to move from the second end 362b to the first end 362a to return to its original position. In other embodiments, one end of each spring 38 can also be hooked on each inserting rod 33, and the other end is arranged and fixed on the surface of the cover plate 221.
