[0002] Mobile phones, tablets and other photographic equipment need to be equipped with a clamping device for clamping and fixing when in use. Currently, the market generally uses a clamping claw type clamping device for clamping and fixing. In the traditional structure, the clamping claw cannot be stored when not in use, resulting in a large size of the clamping device, which is inconvenient to store and is also easy to hook the strap or packaging bag of the clamping device, making it inconvenient to take and put.

[0003] In addition, in traditional clamping devices, the clamping size is fixed and can only be adjusted within a small range, so it is not very universal. It is often necessary to purchase a clamping device that is compatible with the actual application requirements. Summary of the invention

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but only represents selected embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 The present invention discloses a clamping device with a hidden jaw design, including a clamping body 100, on which a first clamping jaw 101 and a second clamping jaw 102 are rotatably arranged. The first clamping jaw 101 and the second clamping jaw 102 have at least two position states during the rotation process, in which the first clamping jaw 101 and the second clamping jaw 102 are retracted relative to the clamping body 100 and fit with its surface in one position state, and in the other position state, the first clamping jaw 101 and the second clamping jaw 102 are unfolded relative to the clamping body 100 to form a clamping space between the first clamping jaw 101 and the second clamping jaw 102.

[0029] In this way, when the clamping device is needed for clamping, the first clamping jaw 101 and the second clamping jaw 102 can be rotated to stand relative to the clamping body 100, thereby forming a clamping space. Figure 2 The state shown in the figure can not only reduce the storage volume, but also facilitate taking and placing, and there will be no problem of hooking other items, which is highly practical. And when the clamping jaws are folded, they fit the surface of the clamping body 100, and a hidden design can be realized. In the actual production process, a recessed position can be set on the surface of the clamping jaw body 100, so that the first clamping jaw 101 and the second clamping jaw 102 are rotated and folded into the recessed position to realize a hidden design. The first clamping jaw 101 and the second clamping jaw 102 can also be rotated until the two side surfaces are flush or almost flush with the upper and lower end surfaces of the clamping body 100 to realize a hidden design, and the overall appearance is better.

[0030] Furthermore, the first clamping jaw 101 is directly rotatably mounted on the clamping body 100, and the second clamping jaw 102 is telescopically mounted on the clamping body 100 via a connecting rod spring structure that is identical to a conventional structure, thereby achieving a normal clamping function.

[0031] like Figure 1 As shown, in this embodiment, one first clamping jaw 101 is provided and is directly rotatably installed on the right end of the clamping body 100 through a pin structure, and two second clamping jaws 102 are provided, and the length of the two second clamping jaws 102 is close to one-half the width of the clamping body 100, and the two second clamping jaws 102 are arranged at the front and rear of the left end surface of the clamping body 100 through a pivot connection. Since the pivot connection method belongs to common knowledge, it will not be described in detail here. The width of the first clamping jaw 101 and the second clamping jaw 102 is close to the thickness of the clamping body 100. In this way, in actual use, the first clamping jaw 101 and the second clamping jaw 102 can be rotated to the state shown in the figure where the second clamping jaw 102 is attached to the clamping body 100 to achieve hidden folding, or they can be rotated to the open state shown in the figure, and clamping is achieved by the cooperation of one first clamping jaw 101 and two second clamping jaws 102.

[0032] Example 2

[0033] This embodiment is based on Embodiment 1, except that in this embodiment, the clamping body 100 is provided with at least two groups of telescopic components that can telescope relative to the first clamping jaw 101 and the second clamping jaw 102, and each group of telescopic components can telescope relative to each other to adjust the distance between the first clamping jaw 101 and the second clamping jaw 102.

[0034] Reference Figure 3Specifically, in the present embodiment, the first clamping jaw 101 is rotatably provided on the clamping body 100, a first telescopic assembly 200 is movably provided on the clamping body 100, a second telescopic assembly 300 which can move relative to its telescopic direction is movably provided on the first telescopic assembly 200, and the second clamping jaw 102 is rotatably provided on the second telescopic assembly 300.

[0035] In order to realize the installation of the first telescopic assembly 200, as Figure 3 As shown, the clamping body 100 is provided with a panel 103 and a bottom plate 104, and a limit plate 106 and a mounting plate 105 are convexly provided on the left and right sides of the bottom plate 104. The first telescopic assembly 200 is a frame structure as shown in the figure, and the limit plate 106 is located in the middle of the frame of the first telescopic assembly 200, so that it is guided and limited by the limit plate 106.

[0036] Furthermore, in this embodiment, a screw adjustment mechanism is provided between the first telescopic assembly 200 and the clamping body 100, so as to adjust the movable stroke of the first telescopic assembly 200 through the screw adjustment mechanism.

[0037] like Figure 3 As shown, the screw adjustment mechanism is provided with an adjustment screw 400 and a slider 401. The adjustment screw 400 is rotatably inserted into the limit plate 106 and the mounting plate 105 of the clamping body 100. The slider 401 is provided with a hole that matches the adjustment screw 400 and is threadedly connected to the adjustment screw 400 and is located between the mounting plate 105 and the limit plate 106. Figure 3 As shown, the slider 401 is also located in the middle of the frame of the first telescopic assembly 200. One end of the adjusting screw rod 400 passes through the mounting plate 105 and extends outside the clamping body 100, and a force-bearing connection structure or action structure is provided at the end to control the rotation of the adjusting screw rod 400, thereby driving the first telescopic assembly 200 to move. The connection structure can be an inner hexagonal nut structure, an outer hexagonal nut structure, a threaded hole, etc., and the action structure can be a rocker, a rudder-shaped structure, etc.

[0038] The second telescopic assembly 300 is disposed inside the first telescopic assembly 200. Figure 4 As shown, a second elastic member 301 is provided to drive the second telescopic assembly 300 to contract, such as a spring, a tension spring, a rubber band, etc.

[0039] When working, the second clamping jaw 102 can be pulled out to cooperate with the first clamping jaw 101 to clamp the clamped object, and then the adjusting screw rod 400 is rotated to pull back the first telescopic assembly 200 to completely clamp the clamped object. This is more reliable than the traditional method of clamping only by tension springs. In addition, the slider 401 can be moved by rotating the adjusting screw rod 400 to adjust the travel range of the first telescopic assembly 200.

[0040] When in use, the clamping device of this embodiment can not only rotate the first clamping jaw 101 and the second clamping jaw 102 to achieve expansion or contraction, but also realize two-stage telescopic adjustment through the cooperation of the first telescopic component 200 and the second telescopic component 300, thereby increasing the clamping size and range of the clamping device and improving the versatility and practicality of the clamping device.

[0041] Example 3

[0042] This embodiment is based on the embodiment 2, except that the screw adjustment mechanism in this embodiment is further provided with a reset member, which is installed between the slider 401 and the first telescopic assembly 200 along the axial direction of the adjustment screw 400. The reset member is preferably set as a spring, which is directly inserted into the adjustment screw 400. Compared with the embodiment 2, the first telescopic assembly 200 does not have a free movement stroke, which can prevent the first telescopic assembly 200 from moving freely when carried out, causing noise or collision with other objects to cause damage, but at the same time, it also has many advantages in the embodiment 2, and is highly practical.

[0043] Example 4

[0044] This embodiment is based on the embodiment 2, but the difference is that the screw adjustment mechanism in this embodiment is only provided with an adjustment screw 400, which is rotatably inserted into the limit plate 106 and the mounting plate 105 of the clamping body 100, and the first telescopic assembly 200 is provided with a hole for matching with the adjustment screw 400 and is threadedly connected with the adjustment screw 400. In this way, the movement of the first telescopic assembly 200 is directly controlled by rotating the adjustment screw 400, so as to achieve the stroke adjustment of the first telescopic assembly 200.

[0045] The structure of this embodiment is simpler than that of embodiment 2, so the production cost is lower. However, since the adjusting screw rod 400 and the first telescopic assembly 200 will receive axial tension, the thread will wear faster and the service life will be shorter.

[0046] Example 5

[0047] This embodiment is based on the embodiment 2, except that Figure 3 and Figure 5 As shown, the adjusting screw rod 400 is provided with an adjusting groove 405 along the circumferential direction, and the central angle corresponding to the adjusting groove 405 is less than 360°. Figure 5 The regulating switch 403 slides left and right in the direction shown, and has a limiter 406 inserted into the regulating slot 405, and the limiter 406 can be withdrawn from the regulating slot 405 during the movement of the regulating switch 403. At the same time, a locking spring 407 is arranged between the clamping body 100 and the regulating switch 403.

[0048] like Figure 3 and Figure 5 As shown, an adjusting sleeve 402 with an outer diameter larger than that of the adjusting screw 400 is provided at the portion of the adjusting screw 400 corresponding to the mounting plate 105, an adjusting slot 405 is opened on the adjusting sleeve 402, and a strip hole is opened on the adjusting switch 403 for the adjusting sleeve 402 to pass through and move, the limiting portion 406 is protrudingly arranged on the inner side of the strip hole, and at the same time, the left end of the adjusting switch 403 passes through the clamping body 100 to form a pressing portion 404, and a locking spring 407 is arranged between the right end of the adjusting switch 403 and the clamping body 100.

[0049] In this way, during the working process, if the pressing part 404 is not pressed, the limiting part 406 is located in the adjusting groove 405, so that the rotation angle of the adjusting screw rod 400 is limited within the range of the central angle of the circle corresponding to the adjusting groove 405. Therefore, in this case, the adjusting screw rod 400 can achieve a fine-tuning function, which can prevent the adjusting screw rod 400 from rotating too much and excessively clamping the clamped object. When it is necessary to rotate the adjusting screw rod 400 within a larger range, the pressing part 404 can be pressed to make the limiting part 406 exit the adjusting groove 405. In summary, the clamping device in this embodiment is safer. The setting of the adjusting sleeve 402 can also enhance the force and extend the service life and stability of the structure.

[0050] Example 6

[0051] This embodiment is based on the fifth embodiment, and the difference is that the adjustment groove 405 in this embodiment is configured as a spiral groove, thereby increasing the range of rotation and movement of the adjustment screw rod 400 when the limiting portion 406 is accommodated in the adjustment groove 405 .

[0052] Example 7

[0053] This embodiment is based on the embodiment 5, except that a fine-tuning groove with a smaller central angle range is further provided in the adjustment groove 405 in this embodiment, and the limiter 406 can be accommodated in the fine-tuning groove. In this way, two-level fine-tuning can be achieved by pressing the pressing part 404 downward.

[0054] Example 8

[0055] This embodiment is based on the embodiment 2, except that, in this embodiment, a first elastic member for driving the first telescopic assembly 200 to contract is provided between the first telescopic assembly 200 and the clamping body 100, and a second elastic member 301 for driving the second telescopic assembly 300 to contract is provided between the second telescopic assembly 300 and the first telescopic assembly 200. The first elastic member and the second elastic member 301 may be springs, tension springs, torsion springs, rubber bands, etc.

[0056] In this way, the folding and closing of the first telescopic assembly 200 and the second telescopic assembly 300 are directly controlled by the first elastic member and the second elastic member 301. The working mode is generally the same as that of the traditional structure, but the two-stage telescopic form can increase the clamping size and expand the scope of application.

[0057] Obviously, in the actual production process, multi-stage telescopic components in the form of three stages, four stages, etc. can also be set.

[0058] Example 9

[0059] This embodiment is based on Embodiments 1-8, except that Figure 6 As shown, the clamping body 100 in this embodiment is provided with an adjusting screw 500, and the adjusting screw 500 is provided with an adjusting nut 501, the adjusting nut 501 is exposed on the surface of the clamping body 100 and is threadedly connected to the adjusting screw 500 to control the movement of the adjusting screw 500 by rotation, and the first clamping jaw 101 is fixedly connected to the adjusting screw 500.

[0060] In this way, during actual use, the movement of the first clamping jaw 101 can be adjusted by rotating the adjusting nut 501 to further expand the range of sizes that can be clamped.

[0061] And if Figure 6 As shown, in the actual production process, two first clamps 101 can be set, and the number of second clamps 102 is set corresponding to the first clamps 101, and the distances between two adjacent first clamps 101 and the corresponding second clamps 102 are different, thereby forming a plurality of clamping spaces with different clamping sizes. In this way, the user can use the first clamp 101 and the second clamp 102 with the clamping size adapted according to actual needs, and rotate and retract the first clamp 101 and the second clamp 102 that are not used. Similarly, when clamping asymmetric objects, the multiple sets of first clamps 101 and second clamps 102 set in this way can be used to cooperate to achieve clamping and fixing, which is highly practical.

[0062] Of course, three or more first clamping jaws 101 may also be provided in the actual production process.

[0063] Example 10

[0064] This embodiment is based on the embodiment 2, and the difference is that the rotation and storage direction of the first clamping jaw 101 and the second clamping jaw 102 in this embodiment is as follows: Figure 7 Shown pivoted inwards.

[0065] The telescopic assembly in this embodiment is also different from that in Embodiment 2, in that the second clamping jaw 102 is mounted on the clamping body 100 via a guide rod and a tension spring structure, while the first clamping jaw 101 is mounted on the clamping body 100 via a screw structure, thereby achieving two-stage telescopic adjustment.

[0066] The above embodiments are only preferred embodiments of the present invention, and the present invention may also have other embodiments, such as reasonably combining the technical solutions recorded in multiple embodiments. Those skilled in the art may also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope set by the claims of this application.
