Background

With the increasing and increasing functions of mobile terminals such as mobile phones, the functions of self-shooting, short video recording, navigation and the like are brought forward, and the functions are often used without leaving a mobile terminal support. The supports of various types, particularly the vehicle-mounted mobile phone support, have a common characteristic, namely, higher requirements on clamping stability and operation convenience are met.

The structure principle of the existing support is that under the action of a spring, clamping plates at two ends of the clamp are kept closed in an idle state, when the support is used, the clamping plates at two ends of the clamp are firstly pulled by two hands, and when the distance between the two clamping plates at the two ends is large enough, a mobile phone is placed between the two clamping plates and then the hands are loosened, so that the clamping plates are automatically closed under the action of the spring, and the mobile phone is clamped and fixed. However, the support can be operated by two hands at the same time in each operation, so that the support cannot be normally used in some scenes in which only one hand is available, and the use is extremely inconvenient.

In this embodiment, the second clamping plate 3 and the adjusting base 30 are integrally formed. Specifically, the cross sections of the adjusting seat 30 and the supporting plate 1 are rectangular, and four surfaces surrounding the adjusting seat 30 for one circle are flush with corresponding surfaces of the supporting plate 1. The tail end of the supporting plate 1 is provided with a guide section 12 with a reduced section in the extension direction, the head end (opposite to one end of the supporting plate 1) of the adjusting seat 30 is provided with a cavity 300 for nesting the guide section 12, and the adjusting seat 30 can slide along the guide section 12 to change the distance between the first clamping plate 2 and the second clamping plate 3, so that the width of a clamping space is adjusted.

The clamp is further provided with an adjusting mechanism for adjusting the clamping space, and the adjusting mechanism comprises a screw 31 penetrating through the adjusting seat 30 and an adjusting nut 32 matched with the screw 31. As shown in fig. 3, 5 and 6, the screw 31 is fixed at the root at the center of the end surface of the guide section 12, and the end extends along the length direction of the support plate 1 and penetrates the adjusting seat 30. The adjusting nut 32 is screwed on the outer side of the adjusting seat 30, and the adjusting seat 30 is pushed to move inwards by screwing the adjusting nut 32. The adjusting mechanism further comprises a compression spring 33, and the expansion direction of the compression spring 33 is consistent with the sliding direction of the adjusting seat 30, namely the compression spring 33 can expand and contract along the length direction of the supporting plate 1. One end of the pressure spring 33 is arranged at the end part of the guide section 12, and the other end is abutted against the bottom of the cavity 300. Specifically, two blind holes 120 are respectively formed in two sides of the end surface of the guide section 12, the two blind holes 120 are symmetrically distributed on two sides of the screw 31, and one end of the pressure spring 33 can be inserted into the blind holes 120. The bottom of cavity 300 is further provided with a support pillar (not shown) extending along the extension direction of compression spring 33, and the other end of compression spring 33 can be sleeved on the support pillar. The diameter of the supporting column is smaller than the inner diameter of the blind hole 120, so that the supporting column can enter the blind hole 120 along with the movement of the adjusting seat 30 in the clamping direction, and the maximum stroke of the adjusting seat 30 cannot be shortened.

As shown in fig. 3, the tail of the screw 31 is further provided with a limit screw 35, the diameter of the tail of the limit screw 35 is larger than the aperture of the adjusting nut 32, and the limit screw 35 prevents the adjusting nut 32 from separating from the screw 31 after reaching the extreme position. The end of the screw rod 31 is provided with a screw hole matched with the limit screw 35, and during assembly, the limit screw 35 penetrates through the adjusting nut 32 and is screwed into the screw hole at the end of the screw rod 31, so that the limit screw 35 is fixedly connected with the screw rod 31.

By adopting the structure design, when the adjusting nut 32 is screwed inwards, the adjusting nut 32 pushes the adjusting seat 30 to move inwards, at the moment, the pressure spring 33 stores energy, and the distance between the first clamping plate 2 and the second clamping plate 3 is gradually reduced (the width of a clamping space is reduced); when the adjusting nut 32 is screwed outwards, the compressed spring 33 extends and pushes the adjusting seat 30 to move outwards synchronously along with the adjusting nut 32, and the distance between the first clamping plate 2 and the second clamping plate 3 is gradually increased (the width of the clamping space is increased). In addition, the reasoning that the pressure spring 33 is applied to the adjusting seat 30 enables the adjusting seat 30 to be always tightly attached to the adjusting nut 32, so that the damping generated when the adjusting nut 32 is screwed is increased, and the adjusting nut 32 has a certain self-locking function under the non-active operation. For ease of operation, the outer surface of the adjustment nut 32 is also provided with a handle 320 to facilitate manual screwing.

The following describes the operation process of the mobile terminal support specifically by taking a mobile phone as an example. When needs centre gripping cell-phone, because first splint 2 can carry out the rotation of certain angle, realizes the dilatation of small-size a little, only needs the one hand to support the cell-phone one side frame at 3 internal surfaces of second splint, presses the frame of opposite side to gyro wheel 23 below again and can accomplish the centre gripping operation, presses the in-process again, and the rotation of gyro wheel 23 can play the direction and reduce frictional effect. When the mobile phone needs to be taken down, the mobile phone is only required to be lifted upwards to be positioned on one side of the roller 23, and the edge of the mobile phone positioned on the side is firstly separated from the first clamping plate 2 along with the rotation of the roller 23, so that the mobile phone can be taken down smoothly. The whole loading and unloading operation can be completed by one hand, and the operation is very convenient. In addition, for the same type of mobile phone, the distance between the first clamping plate 2 and the second clamping plate 3 can be adjusted by screwing the adjusting nut 32 according to the width of the mobile phone when the mobile phone is used for the first time, and the mobile phone does not need to be adjusted again when being subsequently installed or disassembled.
