Door plant connection structure 1 includes procapsid 11 and back casing 12 of mutual lock, be provided with preceding mating plate 13 and back mating plate 14 between procapsid 11 and the back casing 12, a plurality of countersunk screw hole 141 have been seted up to back mating plate 14, it is equipped with screw 4 to fix inserting in countersunk screw hole 141, screw 4 is most advanced to the extension of mating plate 13 direction, seted up on the preceding mating plate 13 and indulged regulation hole 131, screw 4 passes and indulges regulation hole 131, and door frame fixed connection, it is greater than the diameter of screw 4 to indulge the highly of regulation hole 131, it is about 3-4 times of screw 4 diameter to indulge the height of regulation hole 131.

The front shell 11 is provided with a transverse bar hole 111 matched with the longitudinal adjusting hole 131, the middle part of the front matching plate 13 is integrally formed with a clamping center block 132 with the same height as the transverse bar hole 111, the clamping center block 132 is clamped in the middle part of the transverse bar hole 111 and used for restraining the front matching plate 13 from generating Y-direction displacement relative to the front shell 11, the horizontal length of the transverse bar hole 111 is larger than the width of the clamping center block 132, and the horizontal length of the transverse bar hole 111 is 2-3 times of the width of the clamping center block 132, so that the front matching plate 13 can move in the X direction relative to the front shell 11.

In this embodiment, the upper portion and the lower portion of the rear matching plate 14 are respectively provided with two symmetrical countersunk threaded holes 141, the upper portion and the lower portion of the front matching plate 13 are respectively provided with two longitudinal adjusting holes 131 matched with the screws 4, clamping center blocks 132 are integrally formed between the two longitudinal adjusting holes 131 on the upper portion of the front matching plate 13 and between the two longitudinal adjusting holes 131 on the lower portion of the front matching plate 13, and correspondingly, the front housing 11 is provided with two upper and lower horizontal bar holes 111.

In addition, a column-shaped protrusion 1321 is integrally formed in the middle of the retaining center block 132.

The side projections 133 are integrally formed on both sides of the front engagement plate 13, the T-shaped guide grooves 142 are integrally formed on both sides of the rear engagement plate 14 in the direction toward the front engagement plate 13, and the side projections 133 can slide up and down under the restraint of the T-shaped guide grooves 142, so that the front engagement plate 13 can move in the Y direction with respect to the rear engagement plate 14 and cannot displace in the X direction.

The top of back cooperation board 14 integrated into one piece has threaded sleeve 143, has inserted vertical bolt 15 in the threaded sleeve 143, and vertical bolt 15 tip cover is equipped with vertical adjusting nut 16, and preceding cooperation board 13 back is seted up and is cooperated groove 134 with threaded sleeve 143 assorted.

Threaded holes 135 are formed in the side face of the middle of the front matching plate 13, transverse bolts 17 are inserted into the threaded holes 135, and transverse adjusting nuts 18 are sleeved at the end portions of the transverse bolts 17.

The front case 11 is formed with an upper adjustment operation opening 112 through which the vertical adjustment nut 16 is exposed, and the front case 11 is formed with a lower adjustment operation opening 113 through which the horizontal adjustment nut 18 is exposed.

The adjustment operation opening serves two functions, first, the adjustment nut is exposed, the adjustment nut can be rotated externally by a user through the adjustment operation opening, and second, the position of the adjustment nut is limited, so that the relative position of the adjustment nut with respect to the front case 11 cannot be changed, and then the front mating plate 13 or the rear mating plate 14 which is in threaded connection with the adjustment nut moves with respect to the front case 11.

The door frame connecting structure 2 has a sleeve boss 21 integrally formed on one side thereof, a connecting sleeve 114 integrally formed on one side of the front housing 11, and the positioning pin 3 is inserted into the sleeve boss 21 and the connecting sleeve 114.

The middle part of the front shell 11 is also provided with an observation window 115, the observation window 115 is matched with a threaded hole 135 which is protruded at the middle part of the front matching plate 13, on one hand, the position of the front matching plate 13 relative to the front shell 11 is further restrained, and on the other hand, the position of the internal structure can be observed.

The user can adjust the Y-direction position of the door panel by rotating the longitudinal adjusting nut 16 at the upper adjusting operation opening 112, and can adjust the X-direction position of the door panel by rotating the transverse adjusting nut 18 at the lower adjusting operation opening 113, and the specific working principle is as follows: when the upper adjusting operation opening 112 rotates the longitudinal adjusting nut 16, since the longitudinal adjusting nut 16 is completely limited by the upper adjusting operation opening 112 with respect to the front housing 11, the vertical bolt 15 screwed with the longitudinal adjusting nut 16 moves up and down, and then drives the rear matching plate 14 to move up and down, and then drives the screw 4 fixedly connected with the rear matching plate 14 to move up and down, and finally drives the door plate fixedly connected with the screw 4 to move up and down, so as to achieve the purpose of accurately adjusting the Y-direction position of the door plate, in this process, the front matching plate 13 cannot generate vertical displacement under the constraint of the clamping center block 132.

When the lower adjusting operation port 113 rotates the transverse adjusting nut 18, because the transverse adjusting nut 18 is completely limited in position relative to the front shell 11 by the lower adjusting operation port 113, the transverse bolt 17 in threaded connection with the transverse adjusting nut 18 moves left and right, and then drives the front matching plate 13 to move left and right, and because the front matching plate 13 and the rear matching plate 14 are restrained by the T-shaped guide groove 142, the two cannot generate displacement in the X direction, therefore, the transverse bolt 17 drives the front matching plate 13 and the rear matching plate 14 to move left and right together, then drives the screw 4 fixedly connected with the rear matching plate 14 to move left and right, and finally drives the door plate fixedly connected with the screw 4 to move left and right, thereby achieving the purpose of accurately adjusting the X-direction position of the door plate.

In the whole adjustment process, procapsid 11 and back casing 12 are motionless, and only procapsid 11 moves with the inside structure of back casing 12, and back cooperation board 14 moves mainly, and two bolt adjustments be back cooperation board 14 for procapsid 11's position, and then the adjustment be the position of door plant for the door frame, make the cooperation of door plant and door frame more accurate.

Finally, it should be noted that: the above description of the orientation, such as up, down, left, right, and the like, is described with reference to the perspective of fig. 1, unless otherwise specified. In addition, the Y direction is a vertical direction, and the X direction is a horizontal direction. The above embodiments are merely illustrative of the technical solutions of the present invention, and not limitative thereof; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
