[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0025] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. Based on this concept, the specific forms and settings of some connection relationships and positional relationships may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0026] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0027] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0029] A conductive plug-in device for spectrum detection equipment provided by the present invention is now described.

[0030] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a conductive plug device for a spectral detection device, including a conductive connector 1 and a device interface 2, the conductive connector 1 includes a plug-in portion 11, a tapered portion 12 and a cable portion 13 connected in sequence, wherein the plug-in portion 11 is used to be inserted into the device interface 2; a protective cylinder 3 coaxial with the tapered portion 12 is arranged around the outer side of the device interface 2, a moving cylinder 4 is coaxially slidably connected inside the protective cylinder 3, and a limiting mechanism 5 for coaxially sleeved on the tapered portion 12 is arranged inside the moving cylinder 4; a rotating cylinder 6 is coaxially rotatably connected inside the protective cylinder 3, and the rotating cylinder 6 is coaxially threadedly connected with the moving cylinder 4; a rotating hole 31 is opened on the outer circumferential surface of the protective cylinder 3, a lever 32 passing through the rotating hole 31 is fixed on the rotating cylinder 6, and a one-way limiting mechanism 7 for limiting the shifting direction of the lever 32 is arranged between the lever 32 and the protective cylinder 3, when the one-way limiting mechanism 7 limits the direction of the lever 32, the rotation of the lever 32 and the rotating cylinder 6 drives the moving cylinder 4 to move toward the device interface 2.

[0031] The present embodiment provides a conductive plug device for spectral detection equipment. Compared with the prior art, when conducting conductive plugging, the plug-in portion 11 on the conductive connector 1 is first inserted into the device interface 2 in whole or in part after passing through the protective tube 3 and the movable tube 4. At this time, the limiting mechanism 5 in the movable tube 4 is sleeved on the conical portion 12, and the lever 32 is moved to rotate the rotating tube 6. The rotating tube 6 drives the movable tube 4 to move toward the device interface 2 through the thread, and then the limiting mechanism 5 drives the plug-in portion 11 to be completely inserted into the device interface 2 through the conical portion 12. At this time, the restriction of the lever 32 by the unidirectional limiting mechanism 7 prevents the movable tube 4 and the limiting mechanism 5 from moving outward, thereby improving the plug-in stability between the conductive connector 1 and the device interface 2, thereby improving the conductive stability, and the plug-in process does not require the conductive connector 1 to be plugged in and out with force, thereby improving the conductive plug-in efficiency; the protective tube 3 can protect the conductive connector 1 and the device interface 2, so that the whole is stable and safe after the conductive plug-in.

[0032] like Figure 2 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0033] An insulating rubber pad 21 for the plug-in portion 11 to squeeze is provided at the bottom inner end of the device interface 2 .

[0034] The insulating rubber pad 21 can buffer the movement of the conductive connector 1 pushed by the limiting mechanism 5, thereby improving the plug-in safety.

[0035] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0036] The limiting mechanism 5 includes a limiting ring 51 composed of two limiting half rings 511 and a connecting component 52 for driving the two limiting half rings 511 to connect or separate; the limiting ring 51 is coaxially arranged with the moving cylinder 4, and a limiting groove 41 is provided in the moving cylinder 4 for the two limiting half rings 511 to slide away from each other, and the limiting ring 51 is used to be sleeved on the conical part 12.

[0037] When conducting conductive plug-in, the two limiting half rings 511 are first separated by the connecting component 52, and after the plug-in part 11 passes through the two limiting half rings 511 and is inserted into the device interface 2, the two limiting half rings 511 are combined into a whole limiting ring 51 by the connecting component 52. At this time, the limiting ring 51 is just located on the conical part 12, which improves the convenience of operation.

[0038] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0039] The connecting assembly 52 includes a pressing column 521, a connecting rod 522, a sliding rod 523, a containing shell 524 and an extrusion spring 525; a pressing groove 42 is provided on the top of the moving cylinder 4 for the bottom end of the pressing column 521 to rise and fall inside, and a strip-shaped pressing hole 33 is provided on the top of the protective cylinder 3 for the pressing column 521 to pass through and slide inside; a containing groove 43 is provided on one side of the limiting groove 41, and there are two connecting rods 522 and are located in the containing grooves 43, and there are two sliding rods 523 and are fixed one by one on the side of the limiting semi-ring 511 away from each other, and the connecting rods 523 are fixed one by one on the side of the limiting semi-ring 511 away from each other. The top end of the rod 522 is hinged to the pressing column 521, and the bottom end of the connecting rod 522 is hinged to the corresponding sliding rod 523; there are two accommodating shells 524 and they are connected to the two sides of the moving cylinder 4 respectively, and a sliding groove 34 for the accommodating shell 524 to slide is provided in the protective cylinder 3; the sliding rod 523 is slidably connected between the limiting groove 41 and the accommodating shell 524; there are two extrusion springs 525 and they are arranged in the corresponding accommodating shells 524. When the two limiting semi-rings 511 are connected to form a limiting ring 51, the extrusion spring 525 is in a natural or compressed state.

[0040] Specifically, when the two half-rings are connected to form a limiting ring 51, the extrusion spring 525 in this embodiment is in a compressed state, which can improve the stability of the limiting ring 51 after the two limiting half-rings 511 are combined, thereby improving the stability of the limiting ring 51 when pushing the conical part 12 to move.

[0041] When conducting the conductive plugging, the pressing column 521 is first pressed down, and the pressing column 521 drives the two sliding bars 523 to move toward the two accommodating shells 524 through the two connecting rods 522, so that the two limiting semi-rings 511 are moved away from each other to allow the plug-in portion 11 of the conductive connector 1 to pass through, and the extrusion spring 525 is in a compressed state at this time; after the plug-in portion 11 enters the device interface 2, the pressing column 521 is released, and the two extrusion springs 525 drive the corresponding sliding bars 523, connecting rods 522 and pressing column 521 to reset, so that the two limiting semi-rings 511 are combined into a whole limiting ring 51 on the conical portion 12, and the subsequent stable operation of the conductive plugging can be carried out at this time, which improves the overall operation efficiency of connecting or separating the two limiting semi-rings 511. The accommodating shell 524 is used to accommodate the sliding of the sliding bar 523 and the expansion and contraction of the extrusion spring 525 on the one hand, and can cooperate with the slide groove 34 on the other hand to play a guiding role when the moving cylinder 4 slides.

[0042] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0043] A pressing spring 421 connected to the bottom end of the pressing column 521 is disposed in the pressing groove 42 , and the pressing spring 421 is always in a compressed state.

[0044] The setting of the pressing spring 421 can cooperate with the extrusion spring 525 to improve the resetting effect of the pressing column 521, the connecting rod 522 and the sliding rod 523.

[0045] like Figures 2 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0046] Mutually attractive magnets 5111 are embedded on the facing end surfaces of the two limiting half rings 511 .

[0047] The setting of the magnet 5111 can improve the stability of the two limiting half rings 511 after being connected, and thereby improve the stability when the limiting ring 51 drives the conical part 12 to move; and the mutually attractive magnets 5111 can assist the sliding rod 523, the connecting rod 522 and the pressing column 521 in resetting when the two limiting half rings 511 are about to be combined into the limiting ring 51.

[0048] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0049] An insertion rod 35 is fixed to the side wall of the slide groove 34 near the device interface 2, and a socket 351 for inserting the insertion rod 35 is provided on the accommodating shell 524 and the slide rod 523; when the rotating cylinder 6 drives the moving cylinder 4 to move toward the device interface 2, the insertion rod 35 is inserted into the socket 351 corresponding to the slide rod 523.

[0050] When the lever 32 is pushed to make the rotating cylinder 6 drive the moving cylinder 4 to move, the insertion rod 35 is inserted into the insertion hole 351 on the sliding rod 523. At this time, the insertion rod 35, on the one hand, guides the sliding of the accommodating shell 524 and the moving cylinder 4, and on the other hand, can fix the position of the sliding rod 523 in the accommodating shell 524, thereby improving the stability of the two limiting semi-rings 511 when pushing the conical part 12.

[0051] like Figure 2 and Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0052] The one-way limiting mechanism 7 includes a pawl 71, an arcuate ratchet 72, a separation assembly 73 and a retaining assembly 74; the pawl 71 is arranged on the lever 32, and the arcuate ratchet 72 is coaxially fixed on the inner wall of the rotating hole 31. When the pawl 71 is engaged with the arcuate ratchet 72, the rotation of the lever 32 and the rotating cylinder 6 will only drive the moving cylinder 4 to move toward the device interface 2; the separation assembly 73 is arranged on the lever 32 and is used to drive the pawl 71 to separate from the arcuate ratchet 72; the retaining assembly 74 is arranged on the lever 32, and the retaining assembly 74 is used to keep the angle of the pawl 71 unchanged when the pawl 71 is separated from the arcuate ratchet 72.

[0053] After the conductive connector 1 is initially inserted into the device interface 2 and the limiting ring 51 is sleeved onto the tapered portion 12, the lever 32 is pushed so that the rotating cylinder 6 drives the movable cylinder 4 to move toward the device interface 2, and the pawl 71 moves on the arc-shaped ratchet teeth 72. At this time, the lever 32 cannot be pushed in the opposite direction, that is, the movable cylinder 4 cannot move in the direction away from the device interface 2, thereby improving the stability and safety of the conductive connector 1 after insertion.

[0054] When the conductive connector 1 needs to be unplugged, the pawl 71 and the arc-shaped ratchet 72 are separated by the separation component 73. At this time, the lever 32 can be pushed in the opposite direction, and the rotating cylinder 6 drives the moving cylinder 4 away from the device interface 2. Then, the two limiting semi-rings 511 are separated by the connecting component 52, and the conductive connector 1 can be easily unplugged, thereby improving the plugging and unplugging efficiency of the conductive connector 1.

[0055] like Figure 2 and Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0056] The separation assembly 73 includes a sleeve 731 and a return spring 732 . The sleeve 731 is slidably sleeved on the lever 32 . The return spring 732 is arranged inside the sleeve 731 and connected to the lever 32 . The pawl 71 is rotatably connected to the sleeve 731 .

[0057] When the conductive connector 1 needs to be unplugged, the sleeve 731 is pressed to separate the pawl 71 from the arc-shaped ratchet 72, the reset spring 732 is compressed, and the sleeve 731 is pushed in the opposite direction, so that the lever 32 and the rotating cylinder 6 drive the moving cylinder 4 away from the device interface 2, thereby improving the separation efficiency of the pawl 71 and the arc-shaped ratchet 72 and improving the convenience of simultaneously pushing the lever 32 in the opposite direction.

[0058] like Figures 4 to 5 As shown, the present invention provides a specific implementation method based on the above implementation method as follows:

[0059] The retaining assembly 74 includes a retaining frame 741 and a retaining spring 742. The retaining frame 741 is fixed on the sleeve 731, and the retaining spring 742 is connected between the retaining frame 741 and the pawl 71. When the pawl 71 is engaged with the arc-shaped ratchet 72, the retaining spring 742 is in a natural state.

[0060] When the sleeve 731 drives the pawl 71 to separate from the arc-shaped ratchet tooth 72, the retaining spring 742 can keep the angle of the pawl 71 unchanged, so that after the sleeve 731 is released, when the reset spring 732 drives the sleeve 731 to reset, the pawl 71 can directly engage with the arc-shaped ratchet tooth 72 again, thereby improving the convenience of operation.
