referring to fig. 1 to 3, an embodiment of the present invention provides a combined type spectroscopic color meter, which is mainly used for ensuring the accuracy of calibration of a measurement port 3, and the spectroscopic color meter includes a color meter body 1 and a housing 2 integrally formed with the color meter body 1, wherein the color meter body 1 includes a measurement port 3 in sliding fit with the bottom of the housing 2, and the measurement port 3 can slide up and down reciprocally relative to the color meter body 1 based on the housing 2, and does not rotate during sliding. The measuring port 3 is aligned with the area to be detected, and the whole data can be displayed through the color meter body 1 to form contrast; in this embodiment, the color measuring instrument body 1, the housing 2 and the measuring port 3 are all conventional mature technologies, and will not be described in detail here.
Two moving assemblies 5 are symmetrically arranged in the shell 2 along the measuring port 3 in a left-right direction, a control assembly 4 movably clamped with the two moving assemblies 5 is also arranged in the shell, and two adjusting blocks 6 movably attached to the two moving assemblies 5 respectively are symmetrically arranged on the outer surface of the measuring port 3 and in the shell 2; when the control component 4 is started to drive the two moving components 5 to move in the same direction, one of the moving components 5 can drive the measuring port 3 to ascend relative to the base 402 and retract into the shell 2 through the corresponding adjusting block 6, and when the measuring port 3 retracts into the shell 2, the control component 2 can drive the moving component 5 to move towards the direction of the color meter body 1 and correspond to the fitting of the measuring port 3. That is, when the control component 4 drives the two moving components 5 to move in the same direction to the right (left), the measuring port 3 can be driven to rise and retract into the housing 2 by the left (right) moving component 5 and the front (rear) adjusting block 6, and then the control component 2 can drive the moving components 5 to rise and attach to the measuring port 3 correspondingly to complete black (white) correction.
Referring to fig. 1 to 5, in the present embodiment, it is preferable that: the control assembly 4 comprises an electric push rod 401 and a wedge block 404 which are fixedly connected with the inner wall of the shell 2, a base 402 which is movably clamped with the two moving assemblies 5 is fixedly arranged on an output shaft of the electric push rod 401, and the whole base 402 is L-shaped. Specifically, the left and right sides of the base 402 are provided with the dovetail grooves 403, the base 402 and the moving component 5 form movable clamping through the dovetail grooves 403, the moving component 5 can synchronously move left and right along with the base 402 through the dovetail grooves 403, and meanwhile, the moving component 5 can reciprocate relative to the color measuring instrument body 1 based on the dovetail grooves 403. When the moving assembly 5 moves synchronously with the base 402 and contacts with the wedge block 404, the wedge block 404 can drive the moving assembly 5 to lift based on the dovetail groove 403, so as to form fit correspondence with the measuring port 3.
In the above structure, the electric push rod 401 may be replaced by a power source such as an air cylinder, and the dovetail groove 403 may be replaced by a through groove (such as a cross groove, a pentagonal groove, etc.) with other shapes, so long as the moving assembly 5 can be driven to move synchronously and the moving assembly 5 can slide. Because the wedge block 404 can drive the moving assemblies 5 at two sides to lift based on the dovetail grooves 403, the two sides of the wedge block 404 are provided with inclined planes, and in this embodiment, the wedge block 404 is designed as an isosceles triangle, and of course, the wedge block 404 can also be designed as an equilateral triangle or an isosceles trapezoid, as long as the two sides of the wedge block 404 have the same inclined plane.
Further, the moving component 5 includes a clamping block 502 movably clamped with the dovetail groove 403 and a sliding plate 501 fixedly connected with the clamping block 502, a correcting plate 503 for correction is fixedly installed on the surface of the sliding plate 501, specifically, the correcting plate 503 is divided into a blackboard and a whiteboard and is respectively arranged on the sliding plates 501 on two sides, and in this embodiment, the blackboard is positioned on the left sliding plate 501; meanwhile, the whole sliding plate 501 is comma-shaped, and one end of the sliding plate, which is far away from the clamping block 502, is round, so that the correction plate 503 is convenient to install and can be better corresponding to the measuring port 3. In order to adapt to the wedge block 404, a guiding groove 505 is formed at the bottom of the clamping block 502 and near one side of the wedge block 404, the clamping block 502 is not driven to move at the initial stage of contact between the guiding groove 505 and the wedge block 404, and the clamping block 502 is driven to slide based on the dovetail groove 403 only when the end section of the guiding groove 505 contacts the wedge block 404. Meanwhile, a bracket 504 which is movably attached to the corresponding adjusting block 6 is slidably arranged on the surface of the sliding plate 501, when the bracket 504 is close to the corresponding adjusting block 6, the measuring port 3 can be driven to move towards the direction of the color meter body 1 and retract into the shell 2, and when the bracket 504 is far away from the corresponding adjusting block 6, the bracket 504 on the other sliding plate 501 can be driven to move towards the direction of the color meter body 1 through the corresponding adjusting block 6 and retract into the shell 2; specifically, the bracket 504 may slide up and down based on the sliding plate 501, and the bracket 504 cannot deviate in the left-right direction relative to the sliding plate 501, which may be implemented in various manners such as a cross slot, a polygonal slot, or a circular slot, so that the bracket 504 is not affected when the sliding plate 501 moves up and down.
In the above structure, the guiding groove 505 has a horizontal section parallel to the inner bottom wall of the housing 2 and an inclined section, and the inclined section is set identically to the inclined plane of the same side of the wedge block 404, so that the horizontal section of the guiding groove 505 contacts with the top of the wedge block 404 at the initial stage of movement of the clamping block 502, at this time, the wedge block 404 cannot drive the clamping block 502 to move, and the inclined section of the later stage guiding groove 505 contacts with the inclined plane of the wedge block 404, at this time, the wedge block 404 drives the clamping block 502 to rise along the dovetail groove 403.
Further, as shown in fig. 5, the adjusting block 6 is fixedly installed on the outer surface of the measuring port 3 and is correspondingly designed from front to back, the opposite attaching sides of the adjusting block 6 and the brackets 504 are provided with slopes, the slopes of the adjusting blocks 6 on the front and back sides are oppositely designed, and the directions of the slopes on the two brackets 504 are opposite, so that when any one bracket 504 approaches the corresponding adjusting block 6, the measuring port 3 can be driven to move and retract into the housing 2, and at the moment, the other bracket 504 is far away from the corresponding adjusting block 6 to form a separated state.
In order to be suitable for measurement when the measurement port 3 is upward and the color meter body 1 is downward, a first spring (not shown in the figure) may be fixedly mounted on the top of the fixture block 502, and the first spring may be pressed when the dovetail groove 403 of the fixture block 502 is lifted up without being connected with the housing 2 and may move left and right synchronously with the fixture block 502. Meanwhile, a second spring (not shown in the figure) may be fixedly installed at the top of the adjusting block 6 so that the measuring port 3 does not automatically move into the housing 2 due to gravity when the measuring port 3 is upwardly measured.
When the blackboard calibration device is used, the electric push rod 401 is started to drive the two sliding plates 501, the blackboard, the white boards and the two brackets 504 to move right synchronously through the base 402, the dovetail groove 403 and the clamping blocks 502, at the moment, the brackets 504 at the rear side are separated from the adjusting blocks 6 at the rear side, the brackets 504 at the front side drive the measuring port 3 to ascend and retract into the shell 2 through the slopes and the adjusting blocks 6 at the front side, then the inclined section of the guide groove 505 on the left clamping block 502 is contacted with the left inclined surface of the wedge block 404, and the left clamping block 502, the sliding plates 501 and the blackboard are driven to ascend and correspond to the measuring port 3 in a fitting manner, and at the moment, the rapid calibration of the measuring port 3 on the blackboard can be realized.
Then start electric putter 401 drive slide 501, blackboard, whiteboard and two supports 504 move left in step for left side fixture block 502 and wedge 404 separation, front side support 504 and front side regulating block 6 separation, and make rear side support 504 and rear side regulating block 6 be close to the contact, and then drive measuring port 3 again and rise and draw into casing 2, then the inclined section of guide slot 505 on the right side fixture block 502 and the right side inclined plane contact of wedge 404, drive right side fixture block 502, slide 501 and whiteboard rise and correspond with measuring port 3 laminating, can realize measuring port 3 to the quick calibration of whiteboard this moment.
When the blackboard is used, the measuring port 3 can be normally exposed to finish measurement, and when the blackboard is transported after being used, the electric push rod 401 can be started to retract the measuring port 3 into the shell 2, and the blackboard is adjusted to be in a state corresponding to the attachment of the measuring port 3.
In summary, through the cooperation of the structures such as the sliding plate 501, the clamping block 502, the base 402, the adjusting block 6 and the like, the quick calibration of the measuring port 3 and the blackboard and the whiteboard can be realized, meanwhile, the blackboard and the whiteboard are close to the measuring port 3 to form a fit correspondence during the calibration, and further, the clearance can be avoided to improve the correction accuracy of the measuring port 3; because the blackboard and the whiteboard are finally close to the measuring port 3, the abrasion of the blackboard and the whiteboard can be effectively reduced, and the service life is prolonged. The integrated structure is compact, the blackboard and the whiteboard are combined with the shell 2 and the color meter body 1 to form a whole, the whole occupied space can be effectively reduced, and the possibility of dirt due to dust pollution of the blackboard and the whiteboard can be effectively reduced when the blackboard and the whiteboard are contained in the shell 2. After the use, the measuring port 3 can be retracted into the shell 2 and is attached to the blackboard, so that the protective sleeve assembled for the measuring port 3 is omitted, meanwhile, the protective sleeve assembled for the blackboard and the whiteboard is also omitted because the blackboard and the whiteboard are accommodated in the shell 2, further, the working cost is greatly saved, and the overall practicability is higher.
Embodiment two:
referring to fig. 1 to 6, in order to further reduce the dust contamination possibility of the blackboard and whiteboard according to the first embodiment, the sliding board 501 includes a base plate 5011 fixedly connected to the fixture block 502 and a fitting component 7 slidably fitted to the base plate 5011 up and down, the fitting component 7 is based on the same sliding direction of the base plate 5011 and the measuring port 3, and at the same time, a side of the fitting component far from the base plate 5011 is in a fitting state with an inner bottom wall of the housing 2, and the blackboard (whiteboard) is mounted on the base plate 5011. When the bottom board 5011 moves along with the fixture block 502 toward the measuring port 3, and the blackboard (whiteboard) and the measuring port 3 are attached, the attaching assembly 7 can close the opening 201 exposed out of the housing 2 after the measuring port 3 is retracted, and the opening 201, that is, the housing 2 is opened for sliding of the measuring port 3.
Referring to fig. 1 to 7, in the present embodiment, it is preferable that: the fitting assembly 7 comprises a ferrule 701 which is in sliding fit with a bottom plate 5011 up and down, a plurality of third springs 702 are fixedly arranged between the top of the ferrule 701 and the bottom plate 5011, and the ferrule 701 has a trend away from the bottom plate 5011 under the action of the third springs 702.
Further, to ensure that ferrule 701 forms a complete circle at the bottom of base plate 5011 and thus completely encloses opening 201, the sliding fit of bracket 504 to bracket 504 of base plate 5011 needs to be offset from ferrule 701 to fit the bottom of base plate 5011 to form a seal against opening 201. Meanwhile, an annular groove 5012 is formed in the bottom of the bottom plate 5011 for slidably mounting the ferrule 701.
When the automatic correction device is used, the electric push rod 401 is started to be matched with structures such as the base 402, the bracket 504, the adjusting block 6 and the wedge block 404, the blackboard is driven to move right and close to the measuring port 3 to be attached to complete the correction of the blackboard, then the whiteboard is driven to move left and also close to the measuring port 3 to be attached to complete the correction of the whiteboard, and the working process and the effect of the automatic correction device are the same as those of the first embodiment, and repeated description is omitted. The difference is that: when the bottom board 5011 drives the blackboard (whiteboard) to move, the bottom ferrule 701 is driven to move synchronously, and when the bottom board 5011 approaches to the measuring port 3 and is attached under the action of the clamping block 502 and the wedge block 404, the ferrule 701 keeps the attached state with the inner bottom wall of the housing 2 under the action of the third spring 702, that is, the ferrule 701 and the bottom board 5011 form a telescopic structure, and the ferrule 701 covers the opening 201 and is matched with the bottom of the bottom board 5011 to be completely blocked.
In the first embodiment, although the accuracy of the calibration can be effectively improved and the cleanliness of the blackboard (whiteboard) can be ensured by attaching the blackboard (whiteboard) close to the measuring port 3, the calibration of the blackboard and whiteboard with the measuring port 3 needs to last for a certain time (not instantaneously) when the blackboard and whiteboard are calibrated, at this time, the sliding plate 501 is far away from the inner bottom wall of the housing 2 and the measuring port 3 is retracted into the housing 2, so that the opening 201 of the housing 2 is exposed and has a gap, and impurities such as dust still can enter the housing 2 during the calibration of the blackboard (whiteboard), thereby causing pollution of the blackboard (whiteboard) and having a certain use limitation.
Compared with the first embodiment, through the cooperation of structures such as the bottom plate 5011, the fixture block 502, the casing 2 and the support 504, when the bottom plate 5011 is close to the measuring port 3 and forms the laminating correspondence to accomplish the correction, the lasso 701 remains the laminating state with the diapire in the casing 2 all the time, can cover the opening 201 after moving in place along with the bottom plate 5011, the bottom of cooperation bottom plate 5011 can block the opening 201 completely, and then stopped the possibility that debris such as dust get into in the casing 2, the long-term cleanliness of blackboard and whiteboard has been guaranteed, and then alleviateed the trouble of user and can guarantee the accuracy of follow-up long-term calibration, the whole operation combines together with the removal of bottom plate 5011, also can not influence the removal of support 504 for bottom plate 5011, the suitability is stronger.
Embodiment III:
referring to fig. 1 to 9, in order to further ensure the cleanliness of the blackboard and whiteboard, a cleaning component 8 for cleaning the measuring port 3 is disposed on the inner bottom wall of the housing 2, the cleaning component 8 corresponds to the ferrule 701, and when the ferrule 701 moves along the inner bottom wall of the housing 2 along with the bottom board 5011, the ferrule is contacted with the cleaning component 8, so that the cleaning component 8 can be driven to clean the measuring port 3 effectively.
Referring to fig. 1 to 10, in the present embodiment, it is preferable that: the cleaning unit 8 comprises an elastic air bag 801 fixedly embedded on the inner bottom wall of the shell 2, the elastic air bag 801 protrudes relative to the inner bottom wall of the shell 2 and can be contacted with the ferrule 701, one side of the elastic air bag 801 is communicated with a one-way air outlet 802 communicated with the opening 201, and the other side of the elastic air bag 801 is communicated with a one-way air inlet capable of sucking air from the outside of the shell 2. Both the unidirectional air outlet 802 and the unidirectional air inlet may be implemented by unidirectional valves, which are well known and well-established techniques, and will not be described in detail herein.
In the above structure, the unidirectional air outlets 802 are arranged in an annular array along the opening 201, meanwhile, the unidirectional air outlets 802 can be in an inclined design and be inclined to point to the outside of the shell 2 (so as to continuously blow air out of the shell 2 during air exhaust), when the ferrule 701 moves along the inner bottom wall of the shell 2, the elastic air bag 801 can be extruded, the air is exhausted from the unidirectional air outlets 802, and then blowing is realized when the measuring port 3 is contracted into the shell 2; and then is sucked from the outside through the one-way air inlet when the elastic balloon 801 is contracted. In order to ensure the continuity of the exhaust, the portion of the elastic balloon 801 protruding from the inner bottom wall of the housing 2 is provided in plurality and arranged in an array along the moving direction of the ferrule 701.
Further, a gap exists between the bottom of the bottom plate 5011 and the portion inside the annular groove 5012 (i.e., the portion inside the collar 701) and the inner bottom wall of the housing 2, so that the elastic balloon 801 can be automatically reset after passing through the collar 701 into the bottom of the bottom plate 5011.
During the use, drive blackboard and whiteboard to be close to measuring port 3 laminating and accomplish blackboard and whiteboard correction through the cooperation of structures such as base 402, support 504, regulating block 6 and wedge 404, and the opening 201 is plugged up when measuring port 3 and blackboard (whiteboard) are correcting through the cooperation of structures such as bottom plate 5011, fixture block 502, casing 2 and support 504, and this part operational process and effect are the same as in embodiment two, and repeated here is not repeated. The difference is that: when the measuring port 3 moves into the shell 2 and is retracted into the shell 2 under the action of the adjusting block 6 and the bracket 504, the bottom plate 5011 drives the ferrule 701 to move horizontally along the inner bottom wall of the shell 2, so as to continuously contact with the parts of the elastic air bag 801 protruding out of the shell 2, and the elastic air bag 801 is caused to continuously exhaust through the unidirectional air outlet 802, so that the measuring port 3 is effectively purged to clean dust; when the collar 701 is separated from the convex portion of the elastic balloon 801, the elastic balloon 801 can be automatically restored and sucked from the outside through the one-way air outlet 802.
In the second embodiment, the opening 201 is completely blocked by the collar 701 and the bottom plate 5011, but since the measurement port 3 is always in contact with the outside to complete the measurement, a certain amount of impurities such as dust will adhere to the measurement port 3 itself, and when the calibration is completed by attaching the blackboard and the whiteboard, the impurities such as dust will be transferred to the blackboard and the whiteboard, and the blackboard and the whiteboard will be polluted, which has a certain limitation in use.
Compared with the second embodiment, through the cooperation of the structures such as the ferrule 701, the housing 2, the elastic air bag 801 and the unidirectional air outlet 802, when the ferrule 701 moves along the inner bottom wall of the housing 2 along with the bottom plate 5011, on one hand, the opening 201 is covered and matched with the bottom plate 5011 to form a closed structure, and on the other hand, the part of the elastic air bag 801 protruding out of the housing 2 is continuously contacted with the unidirectional air outlet 802, so that the unidirectional air outlet 802 continuously exhausts the measuring port 3 to form a blowing structure to effectively clean impurities such as dust, and meanwhile, the continuously blowing structure enables the impurities such as external dust to not enter the housing 2 from the opening 201 when the measuring port 3 moves into the housing 2, and the impurities such as external dust cannot be brought into the housing 2 through the measuring port 3 to contact with a blackboard (whiteboard), so that the impurities such as dust cannot enter the housing 2 from the opening 201, thereby effectively ensuring the cleanliness of the blackboard and the whiteboard and the accuracy of subsequent long-term calibration, and the whole operation is combined with the movement of the ferrule 701, thereby meeting more requirements in actual use.
