Specifically, one end of the first housing 110 is rotatablely connected with cover board 160 so that the first housing 110 and cover board 160 it Between can relatively rotate, and the first housing 110 and cover board 160 are relatively-stationary in the axial direction of through hole 161.

For example, screw rod 140 is rotatably dispose in the through hole 161, in the present embodiment, screw rod 140 is fixed in the axial direction, example Such as, the circumferential surface of the screw rod 140 along the circumferential direction offers fixing slot, and two surfaces of the cover board 160 abut respectively In the two side walls of the fixing slot, the bottom of fixing slot is abutted with the side wall of through hole 161, in this way, screw rod 140 is in the axial direction Movement is limited by cover board 160 so that screw rod 140 can not move in the axial direction, and screw rod 140 can be rotated in through hole 161 so that Screw rod 140 is rotatably dispose in cover board 160.

Specifically, it can be linear or curved to adjust slide 133, that is to say, that when adjusting slide For linear, adjust slide 133 and be extended along a straight line, and the adjusting slide 133 on each face tilt or perpendicular to First connecting portion 112, for example, the adjusting slide 133 on each face tilts or perpendicular to second connecting portion 122, it should be appreciated that , the inclination said in the present embodiment or vertical first connecting portion 112, that is to say, that adjust slide 133 and first connecting portion 112 It is not parallel, specifically, it is worth being to adjust the joint face that slide 133 is not parallel to first connecting portion 112, the first connecting portion 112 The joint face for connecting babinet is provided with, which is connected to babinet, then each on angle-regulating block 130 discusses shop face to face Adjusting slide 133 tilts or the joint face perpendicular to the first connecting portion 112.It is noted that the first connecting portion 112 is Flat, then the adjusting slide 133 on each face tilt or perpendicular to 112 place plane of first connecting portion.

When adjusting slide 133 to be curved, adjusting slide 133 is set along the surface curvature of angle-regulating block 130.Under In text narration, it will be further elaborated with adjusting slide 133 to be curved.

In the present embodiment, first surface portion 111 and first connecting portion 112 are integrally formed, i.e., described first housing 110 includes Integrally formed first surface portion 111 and first connecting portion 112, the second curved face part 121 and second connecting portion 122 are integrally formed, I.e. described second housing 120 includes integrally formed second curved face part 121 and second connecting portion 122.

For example, first connecting portion 112 and second connecting portion 122 are oppositely arranged, for example, first connecting portion 112 and second connects Socket part 122 is arranged at intervals, for example, first surface portion 111,130 and second curved face part 121 of angle-regulating block are cascading, And first surface portion 111, the crooked radian of 130 and second curved face part 121 of angle-regulating block are mutually matched, for example, first surface Portion 111, the circumferencial direction of 130 and second curved face part 121 of angle-regulating block along screw rod 140 bend and set, it should be appreciated that It is that the first surface portion 111 and second curved face part 121 have identical bending amplitude, and the first surface portion 111 It can be considered a part for cylinder with the cross section of second curved face part 121, then the axial direction of the screw hole 132 and the cylinder It is axially in parallel, therefore, axial direction of 111 and second curved face part 121 of first surface portion parallel to screw hole 132.

It should be understood that the adjusting slide 133 on 130 at least one face of angle-regulating block favours the axial direction of screw hole, Can be the axial direction that adjusting slide 133 on a face favours screw hole 132, the adjusting slide 133 on another face parallel to The axial direction of screw hole 132 or, the adjusting slide 133 on two faces favours the axial direction of screw hole 132, and two faces respectively On the adjusting slide 133 favour the screw hole 132 axial angle it is different.For example, slide 133 is adjusted by angle tune One end of locking nub 130 is set to the other end along the axially direction for favouring screw hole 132, and adjusts slide 133 by angle tune One end of locking nub 130 bends to the other end and sets, that is, adjusts slide 133 and set along the curved surface bending of angle-regulating block 130 Put, for example, adjusting slide 133 has the crooked radian identical with angle-regulating block 130, in such manner, it is possible to so that angle-regulating block It can be rotated relative to first surface portion and the second curved face part.

It is noted that the axial direction that slide 133 favours the screw hole 132 is adjusted, so so that adjust slide 133 When being rotated with angle-regulating block 130, and second housing 120 is produced along the axial movement of screw hole 132, adjusting slide 133, So that the second housing 120 is slided along slide 133 is adjusted, and then produce the rotation relative to the first housing 110.

The adjusting slide on two faces favour the screw hole axial angle it is different can be one adjust slide Rail favours the axial direction of screw hole, the axial direction of another parallel screw hole, for example, the adjusting slide 133 on a face favour it is described The axial direction of screw hole 132, adjusts axial direction of the slide 133 parallel to the screw hole 132 on another face, in this way, parallel to described The axial adjusting slide 133 of screw hole 132 is rotated around screw hole 132, another favours the axial adjusting slide of the screw hole 132 The thrust rotated is produced to the second housing 120 while 133 axial movements along screw hole 132 so that the second housing 120 produces The raw rotation relative to the first housing 110.

In order to enable rotation by a larger margin is produced between the first housing 110 and the second housing 120, for example, first slides Portion 113 favours the axial direction of the screw hole 132, and the second sliding part 123 favours the axial direction of the screw hole 132, and first slides Portion 113 favours the axial angle of the screw hole 132 and the second sliding part 123 favours the axial angle of the screw hole 132 Spend different, the first sliding part 113 has a bending amplitude identical with first surface portion 111, and the second sliding part 123 has and the The identical bending amplitude of two curved face parts 121.

In one embodiment, the adjusting slide 133 on two faces favours the axial angle of the screw hole 132 It is different, and the axial both sides tilted respectively towards screw hole 132 of the adjusting slide 133 on two faces.Specifically, with spiral shell Axis centered on the axial direction in hole 132, the adjusting slide 133 on two faces are respectively facing the axial both sides of screw hole 132 and tilt, this Sample, in axial movement of the angle-regulating block 130 along screw hole 132, angle-regulating block 130 passes through inclined first sliding part 113 to the thrust for applying first direction so that the first housing 110 is rotated towards first direction, and due on angle-regulating block 130 Another face on adjusting slide 133 towards second direction tilt, therefore, the adjusting slide 133 to second on another face Housing 120 applies the thrust to second direction, and the second housing 120 is rotated towards second direction, due to first direction and second party To be respectively facing the axial both sides of screw hole 132, therefore so that the first housing 110 and the second housing 120 are respectively facing screw hole 132 two axial side directions rotate so that the first housing 110 and the second housing 120 are respectively facing opposite direction and rotate, energy Enough so that producing rotation by a larger margin between the first housing 110 and the second housing 120 so that angular adjustment is more flexible.

Since the adjusting slide 133 on angle-regulating block 130 in one side is connected to the first sliding part 113, on another side Adjust slide 133 and be connected to the second sliding part 123, therefore, when angle-regulating block 130 produces displacement, the adjusting on two faces Slide 133 respectively will exert a force the first sliding part 113 and the second sliding part 123, and screw rod 140 drives when being rotated on cover board 160 Dynamic angle-regulating block 130 moves along a straight line along the axial direction of screw rod 140, and angle-regulating block 130 is by towards first surface portion 111 Adjusting slide 133 exert a force to the first sliding part 113, i.e., angle-regulating block 130 exerts a force the first housing 110, the first housing 110 Adjusting slide 133 along this towards first surface portion 111 slides, and angle-regulating block 130 exerts a force the second housing 120, and second Housing 120 is slided along adjusting slide 133 on another face on angle-regulating block 130 so that the second housing 120 produces opposite the The rotation of one housing 110.

Specifically, the first connecting portion 112 of the first housing 110 is used to be connected with a babinet 200, and the of the second housing 120 Two connecting portions 122 are used to be connected with another babinet 200, in this way, when the first housing 110 and the second housing 120 relatively rotate, by band Move two babinets 200 to relatively rotate, so as to fulfill the angular adjustment of babinet 200.

In order to enable the rotation of angle regulator 100 is more stable, in one embodiment, as shown in Fig. 2, the lid The quantity of plate 160 is two, and two cover boards 160 are connected to the both ends of first housing 110, the screw rod 140 It is respectively fixedly connected with two cover boards 160, it should be understood that screw rod 140 is to be fixed on two cover boards 160 in the axial direction On, and screw rod 140 is rotatably dispose on two cover boards 160, and in other words, screw rod 140 is rotatably dispose in the logical of two cover boards 160 In hole 161.For example, cover board 160 is rotatablely connected by screw rod 140 and the first housing 110, for example, two cover boards 160 are distinguished The both ends of first housing 110 are rotationally connected with by screw 162.Every one end of i.e. described first housing is connected described in one Cover board, that is, one cover board 160 of one end connection of the first housing 110, another cover board 160 of other end connection, also, the One housing 110 can be rotated relative to two cover boards 160, and the both ends of second housing 120 abut two cover boards respectively 160, i.e., every one end of described second housing is connected to a cover board, that is, one end of second housing is connected to one Cover board, the other end of second housing are connected to another cover board.

In this way, movement of the both ends of the second housing 120 in the axial direction of screw rod 140 is limited by two cover boards 160 respectively, When screw rod 140 rotates so that the angle-regulating block 130 on screw rod 140 produces displacement, and angle-regulating block 130 drives the second housing During 120 movement, the second housing 120 is subject to the power of inclined adjusting slide 133, adjusts slide and the power of the second housing 120 is divided into Along the axial power of screw rod 140, and the power of the radial direction along screw rod 140, and since the both ends of the second housing 120 are by two Cover board 160 is limited, and therefore, the second housing 120 is only in the radially rotation of screw rod 140, in this way, the second housing 120 will produce Relative to the rotation of the first housing 110, and the second housing 120 will not produce opposite first housing in the axial direction of screw rod 140 110 displacement so that the rotation of angle regulator 100 is more stable, and the rotation regulating effect to mosaic screen is more preferably.

In order to enable angle-regulating block 130 can move between two cover boards 160, for example, the angle-regulating block 130 Length be less than the distance between two cover boards 160, i.e., described angle-regulating block 130 is small along the length of the axially direction of screw hole In the distance between two cover boards 160, so so that angle-regulating block 130 can move between two cover boards 160, and then So that angular adjustment is more flexible.
