Embodiment

In order to it is clearer, completely illustrate the technical solution of the utility model, below in conjunction with the accompanying drawings to the utility model It is described further.

As Figure 1-4, the utility model display screen includes mounting bracket 1, display module 2 and fixture 3, and mounting bracket 1 includes Installing plate 11 and fifth hole 12, installing plate 11 are fixed on mounting bracket 1, and fixture 3 includes base 31, stator 32, rotating shaft 33 With clamping element 34, base is provided with holding tank 311, and stator 32 is provided with first through hole 321, and rotating shaft 33 includes rotating shaft main body 331 and first end 332, the diameter of rotating shaft main body 331 is less than first through hole 321, and it is logical that the diameter of first end 332 is more than first Hole 321, after rotating shaft main body 331 inserts first through hole 321, first end 332 terminates in first through hole 321, and first end 332 is put Enter holding tank 311, stator 32 is fixed in fixed seat 31, perpendicular to stator 32, rotating shaft 33 can be with for the axis of rotating shaft 33 Rotate about the axis thereof；Clamping element 34 is to be fixed on helical structure in rotating shaft main body 331, material be preferably the larger iron of rigidity or Person's steel, the helical centre of the helical structure and the diameter parallel of rotating shaft 33 or is overlapped, therefore, each point and fixation on clamping element 34 The distance between piece 32 along the helical structure the projection of the stator 32 circumferentially continuous gradual change, it is preferable that by minimum Value 0 gradually increases.This helical structure of clamping element 34 go for different-thickness by folder object.

Specifically, when the base 31 of fixture 3 being fixed to 2 back side of display module, between clamping element 34 and stator 32 most Small distance is preferably 0, and the radius of spin of clamping element 34 is more than the distance that installing plate 11 is arrived in rotating shaft 33, and rotating shaft 33, which drives, to be clamped Part 34 rotates, and when the rotation of clamping element 34 with installing plate 11 to when being in contact, clamping element 34 starts installing plate 11 and display module 2 Mutually clamp, continue rotating shaft 33, clamping element 34 further presses installing plate 11, and slight deformation occurs for installing plate 11, now Installing plate 11 is not only by a downward pressure, also by the frictional force of a sensing spiral center of clamping element 34, the friction The presence of power makes installing plate 11 be not easy to occur to slide and further consolidated clamping effect with clamping element 34.

Further, the fixture 3 is preferably structure as shown in Figure 3, and clamping element 34 includes the first flat segments 341, spiral shell Revolve section 342, the second flat segments 343 and winding section 344；First flat segments 341 include the second end 341a, the rotating shaft master Body 331 includes the second through hole 331b of radial direction, and first flat segments 341 run through after the second through hole 331b counterclockwise Downward spiral extends the spiral section 342, and the spiral section 342 extends and the fixation after extending to the stator 32 Parallel second flat segments 343 of piece 32 re-extend out winding section 344, and the winding section 344 is wrapped in the rotating shaft main body On 331；The diameter of first flat segments 341 is less than the second through hole 331b diameter, and the second end 341a diameter is more than second and led to Hole 331b diameter, when the first flat segments 341 insert the second through hole 331b, the second end 341a terminates in the second through hole 331b, the settings of the first flat segments 341 ensure that the radius of turn of spiral section 342 be more than rotating shaft 33 arrive between installing plate 11 away from From, the setting of the second flat segments 343 makes the section increase that spiral section 342 is zero with the distance of stator 32, when installing plate 11 is relatively thin, The contact area of installing plate 11 and clamping element 34 can be increased；The setting of winding section 344 can ensure that the end of clamping element 34 is begun It is close to rotating shaft 33 eventually, and is unlikely to be stuck on installing plate 11 and takes, so as to extends the service life of fixture 3.

Further, rotary handle 36 is provided with the fixture 3, the rotating shaft main body 331 is provided with radial direction Third through-hole 331a, the rotary handle 36 are fitted close through the third through-hole 331a and with the third through-hole 331a, The setting of rotary handle 36 enables the spinning movement of rotating shaft 33 single-handedly to complete, without by external tool；And the rotation Leverage can be played well by changing hands handle 36, reach labour-saving purpose, and it is more convenient to be safeguarded after making.

Further, the fixture 3 is also provided with fixed station 35, and the fixed station 35 is fixed with the stator 32 to be connected Connect, the fixed station 35 is provided with fourth hole 351, and the fourth hole 351 and the first through hole 321 are coaxial aperture, institute State rotating shaft main body 331 and run through the fourth hole 351.When because of clamping element 34 being preferably the larger steel of rigidity, fixture 3 it is overall compared with Weight, depends merely on stator 32 and holding tank 311 does not have good fixation, the setting of fixed station 35 can be played with countershaft 33 Further fixation.

Further, the fixed seat 31 is integrally formed with the display module 2, can when producing 2 shell of display module The fixed seat 31 of fixture 3 is molded on shell with settling at one go, can so save and fixed seat 31 is fixed in display module 2 Process, being fixedly connected between fixture 3 and display module 2 be also therefore more firm.

Further, as shown in Figure 1 and Figure 4, the display module 2 is provided with alignment pin 21, and the mounting bracket 1 is provided with Positioning hole 13, the alignment pin 21 are inserted in the positioning hole 13, and the positioning hole 13 and the alignment pin 21 coordinate for gap, After employing this location structure, display module 2 can be positioned quickly on mounting bracket 1, and fixture 3 can be avoided to rotate through The situation of the off normal of display module 2 caused by degree.

Further, display module 2 also includes the 6th through hole 22, and the first end 332 also includes swivelling chute 332a, institute It is mutually corresponding with the swivelling chute 332a positions to state the 6th through hole 22.Outside throw can be rotated by the 6th through hole 22 Swivelling chute 332a, and then the rotation of rotating shaft 33 is driven, after employing this structure, the utility model display screen is easily entered Safeguarded before row.

Certainly, the utility model can also have other numerous embodiments, based on present embodiment, the ordinary skill of this area Personnel obtain other embodiment on the premise of any creative work is not made, and belong to the utility model and are protected Scope.
