DETAILED DESCRIPTION

[0043] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawing, the utility model is further detailed.

[0044] Example 1:

[0045] Please refer to Figures 1 to 8 As shown, the embodiment provides a shielding door, which comprises: door frame 200, door leaf 100 connected with door frame 200 through a hinge, and locking mechanism arranged between door frame 200 and door leaf 100.

[0046] Specifically, the locking mechanism comprises locking seat 81 in the shape of cuboid with hollow cavity arranged on door frame 200, open mouth in communication with hollow cavity arranged on one length direction side end face of locking seat 81, linkage rod 82 penetrating through hollow cavity and suitable for doing translational motion along the width direction of locking seat 81 when doing lifting motion along the length direction of locking seat 81, linkage seat 83 suitable for being inserted into hollow cavity from open mouth and movably sleeved on linkage rod 82; linkage seat 83 is connected with door leaf 100 through connecting plate 85. In an optional case, connecting plate 85 is vertically distributed relative to linkage seat 83.

[0047] Furthermore, one end of each of the pair of length direction side end faces of the locking seat 81 is provided with a slanted slide groove 86 extending to the opening, and the linkage rod 82 is provided with a pair of locking pins 87 adapted to move along the two slanted slide grooves 86 one by one; the slanted slide grooves 86 are distributed in an inclined manner relative to the length direction of the locking seat 81; and the two ends of the linkage rod 82 penetrate through the two width direction side end faces of the locking seat 81, and each of the two width direction side end faces of the locking seat 81 is provided with a U-shaped guide groove 88 extending to the opening.

[0048] It should be noted that the length of the linkage rod 82 is greater than the length of the locking seat 81; and the linkage seat 83 is a cuboid structure, and a pair of length direction side end faces of the linkage seat 83 are respectively provided with a waist-shaped accommodation hole 89 adapted to pass through the pair of locking pins 87.

[0049] For the locking mechanism of the present embodiment, in the case of the linkage rod 82 moving downward as exemplified from the perspective of the drawing, at this time, the opening process of the door leaf 100 relative to the door frame 200 is realized by the downward movement, the bottom of the slanted slide groove 86 is shaped as a notch, and the notch is relatively close to the opening of the locking seat 81, the top of the slanted slide groove 86 is relatively far from the opening of the locking seat 81, in the initial state, the locking pin 87 on the linkage rod 82 is located at the top of the slanted slide groove 86, and at this time, the insertion depth of the linkage seat 83 relative to the hollow cavity reaches the maximum. Based on this condition, with the downward movement of the linkage rod 82, the locking pin 87 on the linkage rod 82 gradually moves along the slanted slide groove 86 to the notch of the slanted slide groove 86. At the same time, the linkage seat 83 sleeved on the linkage rod 82 is limited by the hollow cavity and does not move synchronously with the downward movement of the linkage rod 82, and the linkage seat 83 only translates along the width direction of the locking seat 81, so as to move to the side of the opening of the locking seat 81, so that the linkage seat 83 gradually separates from the locking seat 81, in this process, the linkage rod 82 translates along the U-shaped guide groove 88 on the locking seat 81 during the downward movement. When the linkage rod 82 moves upward, a completely opposite movement process to the above process can be generated, thereby realizing the closing operation of the door leaf 100 relative to the door frame 200, and this process will not be described here.

[0050] Next, the hinge used in the present embodiment includes a fixed seat, a connecting rod 2, a guide assembly, and a hinge assembly used in conjunction.

[0051] Generally, first, the fixed seat is used for fixing on the door frame 200, which includes a seat body 1 in the shape of a cuboid and a hollow accommodating cavity 11 formed in the seat body 1, and the hollow accommodating cavity 11 formed here is also in the shape of a cuboid; and one of the length direction side end faces of the seat body 1 is formed with an opening communicating with the hollow accommodating cavity 11.

[0052] Secondly, the connecting rod 2 is inserted into the hollow accommodating cavity 11 along the length direction of the seat body 1, and the length of the connecting rod 2 is greater than the length dimension of the seat body 1, so that the two ends of the connecting rod 2 respectively extend to the two side ends of the length direction of the seat body 1. Based on this condition, the connecting rod 2 can perform the translational movement along the width direction of the seat body 1 when performing the lifting movement along the length direction of the seat body 1, and in this process, any end of the connecting rod 2 will not enter the hollow accommodating cavity 11 when the connecting rod 2 performs the lifting movement, and the overall connecting rod 2 is approximately cylindrical.

[0053] Furthermore, the guiding assembly includes the lifting guiding group arranged between the connecting rod 2 and the seat body 1, and the movable frame 3 arranged in the hollow accommodating cavity 11 and movably sleeved on the connecting rod 2 and the translational guiding group arranged between the movable frame 3 and the seat body 1. Here, the connecting rod 2 can perform the translational movement along the width direction of the seat body 1 when performing the lifting movement along the length direction of the seat body 1 through the guiding assembly.

[0054] In combination with an optional condition shown in the drawings, more specifically, the lifting guiding group includes two pairs of waist-shaped guiding holes 41 arranged in pairs on the seat body 1 and perpendicular to the length direction of the opening of the seat body 1, and four pin shafts 42 arranged on the connecting rod 2 and suitable for being inserted into each waist-shaped guiding hole 41 of the seat body 1 in one-to-one mode. It should be noted that the two waist-shaped guiding holes 41 on each side end surface of the seat body 1 are parallel to each other, and the long axis of each waist-shaped guiding hole 41 is arranged in an inclined distribution mode relative to the length direction of the seat body 1.

[0055] The translational guiding group includes a pair of waist-shaped positioning holes 51 arranged on the seat body 1 and perpendicular to the length direction of the opening of the seat body 1, and a pair of positioning pin shafts 52 arranged on the movable frame 3 and suitable for being inserted into the pair of waist-shaped positioning holes 51 in one-to-one mode; the long axis of the waist-shaped positioning hole 51 is parallel to the width direction of the seat body 1. It should be noted that, in an optional condition, the waist-shaped positioning hole 51 here is approximately U-shaped, so that the waist-shaped positioning hole 51 has an open mouth, and the open mouth extends to the opening end surface of the seat body 1.

[0056] On the basis of the above structure, it should be further noted that a pair of waist-shaped holes 53 suitable for the four pin shafts 42 to pass through are further arranged on the side wall of the movable frame 3, and the long axis of each waist-shaped hole 53 is parallel to the length direction of the seat body 1. In this regard, in an optional implementation condition, the positioning pin shaft 52 on each length direction side end surface of the movable frame 3 is located between the two waist-shaped holes 53. One waist-shaped movable hole 12 with the long axis parallel to the long axis of the waist-shaped positioning hole 51 is arranged on each width direction side end surface of the seat body 1.

[0057] Furthermore, it is necessary to point out that the four pin shafts 42 are evenly distributed in pairs on the two pairs of side end faces of the connecting rod 2, and the connecting line of the shaft centers of the two pin shafts 42 on the same side end face of the pin shafts 42 is parallel to the length direction of the seat body 1. The movable frame 3 is a cuboid structure; and the four waist-shaped holes 53 are evenly distributed in pairs on the two pairs of length direction side end faces of the movable frame 3, and the connecting line of the long axes of the two waist-shaped holes 53 on the same side end face of the movable frame 3 is parallel to the length direction of the seat body 1.

[0058] Finally, the hinge assembly includes a connecting plate set partially inserted into the hollow movable cavity and movably sleeved on the connecting rod 2, and a gap set provided on one of the length direction side end faces of the seat body 1 and adapted to the connecting plate set to partially move outside the seat body 1 around the connecting rod 2.

[0059] Specifically, the connecting plate set includes a pair of connecting plates 61 inserted into the hollow accommodating cavity 11 from the opening part; the pair of connecting plates 61 are respectively provided on the two sides of the movable frame 3 along the length direction of the seat body 1. The gap set includes a pair of U-shaped grooves 62 provided on one of the length direction side end faces of the seat body 1 and adapted to the pair of connecting plates 61 to move one by one.

[0060] With reference to the perspective view of the drawings, the connecting rod 2 is taken as an example to describe the case of upward movement, which corresponds to the process that the door leaf 100 can be opened relative to the door frame 200, the bottom of the waist-shaped guide hole 41 is relatively far away from the opening of the seat body 1, and the top of the waist-shaped guide hole 41 is relatively close to the opening of the seat body 1. In the initial state, the pin shaft 42 on the connecting rod 2 is located at the bottom of the waist-shaped guide hole 41, and the positioning pin 52 is located at the end of the waist-shaped positioning hole 51 away from the opening of the seat body 1. At this time, the insertion depth of the pair of connecting plates 61 relative to the hollow accommodating cavity 11 reaches the maximum. Based on this condition, as the connecting rod 2 moves upward, the pin shaft 42 on the connecting rod 2 gradually moves to the top of the waist-shaped positioning hole 51 along the long axis direction of the waist-shaped guide hole 41. At the same time, the movable frame 3 sleeved on the connecting rod 2 cannot move synchronously with the upward movement of the connecting rod 2 due to the limiting action of the positioning pin 52. At this time, the positioning pin 52 moves along the waist-shaped positioning hole 51, and the movable frame 3 only translates along the width direction of the seat body 1, so as to move to the outside of the hollow accommodating cavity 11, thereby making the pair of connecting plates 61 located at both ends of the movable frame 3 unable to move up and down with the connecting rod 2, but only able to move translationally with the connecting rod 2, so that the pair of connecting plates 61 can be partially moved to the outside of the hollow accommodating cavity 11 during the movement of the pair of connecting plates 61 toward the opening side of the seat body 1. During this process, the connecting rod 2 moves translationally along the waist-shaped guide hole 12 on the seat body 1 during the upward movement. Based on this, the pair of connecting plates 61 can be rotated around the connecting rod 2, and the pair of U-shaped grooves 62 provides the space required for the rotation of the connecting plates 61. When the connecting rod 2 moves downward, a completely opposite movement process to the above process can be generated, which will not be described herein.

[0061] In addition, the hinge set adopted in the embodiment further comprises a hinge leaf 71 connected to the pair of connecting plates 61 simultaneously; the hinge leaf 71 is perpendicular to the pair of connecting plates 61. In order to facilitate the fixation of the seat body 1 to the door frame 200, the pair of width direction side ends of the seat body 1 are respectively provided with an outwardly turned connecting lug 72.

[0062] In addition, it should be further pointed out that the shielding door further comprises a driving mechanism adapted to simultaneously drive the linkage rod 82 and the connecting rod to move up and down; in combination with the drawings, an optional case is taken as an example, the driving mechanism comprises a connecting shaft 84 connected to the linkage rod 82 and the connecting rod respectively, a rack seat 91 fixed on each connecting shaft 84, a pair of transmission gears 92 engaged with the rack seat 91 on each connecting shaft 84 respectively, a pair of transmission shafts 93 connected to the pair of transmission gears 92 respectively, and a power assembly for simultaneously driving the pair of transmission shafts 93. Here, the rack seat 91 on the connecting rod and the linkage rod 82 can be connected to the door leaf 100 through a sliding fit support seat respectively.

[0063] As to the power assembly here, it can be a bevel gear set used in cooperation, which generally comprises two driven bevel gears fixed on the pair of transmission shafts 93 respectively, and a driving bevel gear engaged with the two driven bevel gears, and the hand wheel 94 is used to drive the driving bevel gear to rotate through the connecting shaft, so that the driving bevel gear can be driven to rotate by rotating the hand wheel 94, thereby driving the pair of transmission shafts 93 to rotate, and further driving the linkage rod 82 and the connecting rod to move up and down under the action of the rack seat 91 and the corresponding transmission gear 92. Of course, the power assembly here can also be of other structures, and the present embodiment does not make absolute limitation thereto.

[0064] In summary, for the shielding door of the present embodiment, the switching between the open and closed states thereof can be realized by controlling the up and down movement of the linkage rod 82 relative to the length direction of the door leaf 100, and in this process, the linkage rod 82 is only driven to move up and down, so that the use process is simple, the driving structure is relatively simple, the practical failure rate is low, and the production cost is controllable. As to the hinge adopted, when the connecting rod 2 moves up and down along the length direction of the seat body 1, it moves along the width direction of the seat body 1, so that the connecting plate set connected with the connecting rod 2 can first move a certain distance along the width direction of the seat body 1 and then rotate relative to the seat body 1. Thus, when it is applied to a specific shielding cabinet door, the shielding door body 100 adopting the hinge can first move a certain distance outward relative to the cabinet door frame 200200 and then rotate, so that the double-spring-leaf shielding assembly is disengaged from the plug during the translational movement of the shielding door body 100 relative to the cabinet door frame 200200, so as to make the shielding door body 100 rotate relative to the cabinet door frame 200200 after the double-spring-leaf shielding assembly is disengaged from the plug. During the closing process of the shielding door body 100, the double-spring-leaf shielding assembly is engaged with the plug by first rotating and then moving translationally. Based on the hinge, compared with the structure of the prior art adopting two hinge shafts, the hinge can meet the requirements of the spring leaf and the plug of the shielding door, and can also reduce the requirement for machining precision, thereby reducing the machining difficulty.
