Fig. 1 to 9 are schematic structural views of the connecting device of the present embodiment. As shown in fig. 1 to 9, the connecting device is used for connecting a first connecting member C and a second connecting member 17, and includes an outer column 1, a lever assembly, at least two moving members 4, at least two keys 5, at least two first elastic members 6 and second elastic members 7, wherein the lever assembly includes at least a first lever 2 and a second lever 3. Wherein, the outer column 1 includes a moving cavity 11 and at least two moving channels 12, preferably, the number of the moving channels 12 is the same as the number of the levers and corresponds to one another, the moving cavity 11 is formed by one axial end surface of the outer column 1 being recessed towards the other end surface, and the moving channels 12 are oppositely arranged on the side wall of the moving cavity 11, as shown in fig. 3, 5 and 8. The moving passage 12 radially penetrates the side wall of the moving chamber 11 to communicate with the moving chamber 11. Preferably, the number of the moving members 4, the number of the keys 5 and the number of the first elastic members 6 are the same as the number of the levers and are in one-to-one correspondence, the second elastic members 7 are arranged between the first lever 2 and the second lever 3, and the number of the second elastic members 7 is preferably at least one less than the number of the levers.
The following description will mainly use the lever assembly as two levers, i.e. the first lever 2 and the second lever 3 as an example.
In this embodiment, the moving channel 12 includes a first channel 121 and a second channel 122 sequentially connected from outside to inside, a radial cross-sectional diameter of the first channel 121 is smaller than a radial cross-sectional diameter of the second channel 122, and a step is formed at a connection position of the two, as shown in fig. 5.
The two moving members 4 are movably disposed in the corresponding moving channels 12, and can be controlled to move in the moving channels 12, as shown in fig. 1 and 2. The moving member 4 includes a first moving portion 41 and a second moving portion 42 connected in sequence from outside to inside, as shown in fig. 3. The first moving portion 41 has a radial sectional diameter smaller than that of the second moving portion 42. The first moving portion 41 is accommodated in the first passage 121 and is movable in the first passage 121, and the second moving portion 42 is accommodated in the second passage 122 and is movable in the second passage 122. Specifically, the first moving portion 41 is adapted to the diameter of the first channel 121, and the second moving portion 42 is adapted to the diameter of the second channel 122, so that the moving member 4 can move smoothly in the moving channel 12, and the connection stability of the connection device is prevented from being affected by shaking.
In this embodiment, the total length of the moving member 4 is greater than the total length of the moving channel 12, and the length of the first moving portion 41 is greater than the length of the first channel 121, so that when the connecting device is in the locking state, the radially outer end of the moving member 4 can extend out from the radially outer end of the moving channel 12 to achieve locking, as shown in fig. 1 and 2.
The two first elastic members 6 are respectively located in the second passages 122, and both ends of the first elastic members 6 respectively abut against the steps formed by the first and second passages 121 and 122 and the steps formed by the first and second moving portions 41 and 42. When the connecting device is in a locking state, the two moving parts 4 move to the radial outer side of the moving channel 12 respectively under the thrust and extend out of the moving channel 12 to be in snap connection. The moving member 4 compresses the first elastic member 6 during the above movement, so that the first elastic member 6 has a reverse elastic force. When the connecting device needs to be unlocked, the user can press the key 5 to cancel the pushing force applied to the moving member 4, and at this time, the moving member 4 moves to the radial inner side of the moving channel 12 under the reverse elastic force of the first elastic member 6, so that the moving member 4 completely moves into the moving channel 12, and the connecting device is switched from the locked state to the open state.
The first lever 2 and the second lever 3 are hinged in a crossed manner and are arranged in the moving chamber 11 in a relatively rotatable manner, as shown in fig. 1 and 2. Wherein the first lever 2 comprises a first part 2a and a second part 2b and the second lever 3 comprises a first part 3a and a second part 3b, as shown in fig. 4. The first portion 2a of the first lever 2 and the first portion 3a of the second lever 3 are identical in structure and are arranged opposite to each other. The second portion 2b of the first lever 2 and the second portion 3b of the second lever 3 have the same structure, and both have a width smaller than the width of the first portion 2a of the first lever 2 and the width of the first portion 3a of the second lever 3. The second part 2b of the first lever 2 and the second part 3b of the second lever 3 are hinged, i.e. the second part 2b and the second part 3b are hinged after being superposed in the width direction.
The moving member 4 further comprises a guide groove 43, and the guide groove 43 is located at the radially inner end of the moving member 4 and is located in the moving chamber 11, as shown in fig. 1 and 2. The width of the guide groove 43 is greater than the width of the second portion 2b of the first lever 2 and the second portion 3b of the second lever 3 so that the second portion 2b of the first lever 2 and the second portion 3b of the second lever 3 are respectively inserted into the guide grooves 43 of the corresponding moving members 4. Further, a second elastic member 7 is provided between the first portion 2a of the first lever 2 and the first portion 3a of the second lever 3, as shown in fig. 4.
When the first portion 2a of the first lever 2 and the first portion 3a of the second lever 3 are subjected to a relative external force, the first lever 2 and the second lever 3 press the second elastic member 7, and relatively rotate to make the distance between the end of the second portion 2b and the end of the second portion 3b smaller and generate a moving distance between the moving members 4 respectively, and the two moving members 4 move to the radial inner side of the moving channel 12 under the reverse elastic force of the corresponding first elastic member 6. Further, when the moving member 4 moves to the inner side of the moving passage 12 to a certain distance, the moving member 4 abuts against the second portion 2b of the first lever 2 or the second portion 3b of the second lever 3, so that the moving member 4 can be prevented from moving into the moving cavity 11 to affect the use of the connecting device.
When the external force of the first portion 2a of the first lever 2 and the first portion 3a of the second lever 3 disappears, the first lever 2 and the second lever 3 are rotated in reverse by the reverse elastic force of the second elastic member 7 so that the distance between the end of the first portion 2a of the first lever 2 and the end of the first portion 3a of the second lever 3 and the distance between the end of the second portion 2b of the first lever 2 and the end of the second portion 3b of the second lever 3 become gradually larger, and the second portion 2b of the first lever 2 and the second portion 3b of the second lever 3 push the corresponding moving member 4 to move radially outward of the corresponding moving passage 12 and compress the first elastic member 6.
In this embodiment, the first elastic member 6 and the second elastic member 7 are provided as compression springs. The first elastic member 6 and the second elastic member 7 may be made of any material having elastic material, and the form of the material is not limited to a spring. The material can also be memory alloy, silica gel, carbon spring steel, alloy spring steel and the like.
In a preferred embodiment, the positions where the second part 2b of the first lever 2 and the second part 3b of the second lever 3 are hinged are symmetrically provided with grooves which are mutually clamped, and after the second part 2b and the second part 3b are hinged in a crossed manner, the ends of the second part 2b of the first lever 2 and the second part 3b of the second lever 3 are completely symmetrical, so that the two moving parts 4 and the two moving channels 12 connected with the second part 2b and the second part 3b are completely symmetrical, which is helpful for determining the positions of the two moving channels 12 and is convenient for rapid production and processing.
The connecting device further comprises a bushing 21 and a guide shaft 22. The guiding shaft member 22 includes a fixing portion and a guiding shaft disposed at one axial end of the fixing portion, and the diameter of the outer circumferential surface of the fixing portion is greater than that of the guiding shaft. The first lever 2 and the second lever 3 are hinged in a crossed manner by the guide shafts and then placed in the moving chamber 11, as shown in fig. 4. Specifically, the shaft sleeve 21 has a connecting hole, and the guide shaft passes through the first lever 2 and the second lever 3 and then extends into the connecting hole of the shaft sleeve 21 and is fixedly connected with the connecting hole, so as to complete the hinge joint of the first lever 2 and the second lever 3, as shown in fig. 4.
The outer column 1 further includes two limiting grooves 19 symmetrically disposed on two radial sides of the moving cavity 11 and respectively located between the two moving channels 12, as shown in fig. 3. Wherein the top and opposite sides of the limiting groove 19 have openings for placing the sleeve 21 and the fixing portion. The shaft sleeve 21 and the fixing part are fixedly arranged in the two limiting grooves 19, so that the first lever 2 and the second lever 3 can be prevented from shaking in the moving cavity 11 to influence the normal use of the connecting device.
In a preferred embodiment, the moving chamber 11 is configured as a rectangular structure, two moving channels 12 are symmetrically disposed on two opposite narrow side walls of the moving chamber 11, two limiting grooves 19 are symmetrically disposed on two opposite wide side walls of the moving chamber 11, and an extension line of the two limiting grooves 19 is perpendicular to an extension line of the two moving channels 12, as shown in fig. 3. The width of the moving cavity 11 is slightly larger than the width of the first lever 2 or the width of the second lever 3 to reduce the shaking of the first lever 2 and the second lever 3 in the moving cavity 11.
The connecting device further comprises two symmetrically arranged connecting plates 8, which are located axially above the outer column 1, as shown in fig. 3 and 8. Wherein, two connecting plates 8 are respectively located at the radial outer side of two limiting grooves 19, and a moving through groove 81 is formed between the two connecting plates 8 and the top surface of the outer column 1, as shown in fig. 8. The moving through slot 81 is in axial communication with the moving chamber 11, as shown in fig. 5. Wherein the first portion 2a of the first lever 2 and the first portion 3a of the second lever 3 respectively protrude from the moving cavity 11 and into the moving through slot 81. The two keys 5 are symmetrically disposed in the through groove 81 and located outside the first lever 2 and outside the second lever 3, respectively, and the first lever 2 and the second lever 3 are relatively rotated by simultaneously pressing the two keys 5 to simultaneously press the first portion 2a of the first lever 2 and the first portion 3a of the second lever 3.
The communication direction of the moving through groove 81 is parallel to the extension lines of the two moving channels 12, so that the moving directions of the two keys 5 are the same as the moving directions of the two moving members 4, and the keys 5 can accurately control the moving of the moving members 4.
The connection device further comprises a housing 9, as shown in fig. 6 and 7. The housing 9 includes a connection hole 91 opened downward and a moving rail 92. The moving rail 92 is located on the top surface of the connection hole 91 and is recessed toward the top of the housing 9, and the moving rail 92 communicates with the connection hole 91 in the depth direction (axial direction), as shown in fig. 7.
The moving rail 92 penetrates the side wall of the housing 9 in the radial direction so that both sides of the housing 9 form a key opening. The shape of the connecting hole 91 is matched with the shape formed by surrounding the outer side faces of the two connecting plates 8, and the depth of the connecting hole 91 is matched with the thickness of the connecting plates 8, so that the two connecting plates 8 are fixedly arranged in the connecting hole 91 and fixedly connected with the shell 9. In this embodiment, the outer side of the connecting plate 8 includes a partial non-circular side, the corresponding position of the connecting hole 91 is the same as the shape of the side of the connecting plate 8, and after the connecting plate 8 is inserted into the connecting hole 91, the connecting plate 8 can be prevented from rotating in the connecting hole 91 to affect the pressing of the key 5.
The moving rail 92 is located at the middle position of the connecting hole 91 in the radial direction, and the moving rail 92 is parallel to the moving through groove 81, so that when the two connecting plates 8 are fixed in the connecting hole 91, the moving through groove 81 is buckled with a part of the moving rail 92 and is communicated in the axial direction. The moving rail 92 passes through the moving channel 81 in the communication direction of the moving channel 81. The width of the moving rail 92 may be less than or equal to the width of the moving through slot 81.
The two keys 5 are symmetrically disposed in the moving track 92 at two radial sides of the connecting hole 91, as shown in fig. 2 and 6. The thickness and width of the two keys 5 are adapted to the depth and width of the moving track 92 to avoid the keys 5 from wobbling when moving within the moving track 92. In this embodiment, one end of the key 5 may protrude from the end of the moving rail 92, and be located outside the housing 9, so as to facilitate the operation of the user. The other end of the key 5 extends into the moving track 92 and the moving through slot 81 and is located outside the first part 2a of the first lever 2 or the first part 3a of the second lever 3, so as to press and push the first lever 2 and the second lever 3 to rotate.
The housing 9 further includes a first fixing groove 93, and the first fixing groove 93 is located at one side of the moving rail 92 and outside the coupling hole 91, as shown in fig. 3.
