[0043] See also Figure 1 and Figure 2 The clamping assembly of the embodiment of the present application is used to clamp electronic devices, such as mobile phones, tablet computers, etc.

[0044] The clamping assembly comprises a bracket 1 , a pressing and locking assembly 3 , and two clamping arms protruding from two ends of the bracket 1 respectively.

[0045] Specifically, Figure 1 and Figure 3As shown, the bracket 1 of this embodiment includes a bracket body 11 and a cover plate 12. The bracket body 11 is generally rectangular in shape, and a through guide groove is provided in the bracket body 11 along the length direction. The guide groove includes two first notch portions 111 located at both ends of the bracket body 11 and a second notch portion 112 located in the middle of the bracket body 11. The width of the first notch portion 111 is smaller than the width of the second notch portion 112 (the extension direction of the guide groove is the length direction, and the other direction perpendicular to it is the width direction, which is consistent with the length and width directions of the bracket body 11). That is, the openings at both ends of the guide groove are small, and the opening in the middle is large, and a limiting step is formed at the connection between the two first notch portions 111 and the second notch portion 112. In this embodiment, in order to reduce the overall weight of the clamping assembly, a through hole is provided at the bracket body 11 corresponding to the second notch portion 112, that is, the bottom of the second notch portion 112 is hollowed out. The cover plate 12 is provided on the side of the bracket body 11 where the guide groove is provided, and the cover plate 12 and the bracket body 11 are detachably connected.

[0046] like Figure 2 and Figure 4As shown, the number of clamping arms in this embodiment is two, and a space for clamping electronic equipment is formed between the surface of the bracket 1 and the two clamping arms. The two clamping arms are respectively arranged on the bracket 1, and the two clamping arms are respectively movable clamping arms 2, or one clamping arm is a movable clamping arm 2, and the other clamping arm is a fixed clamping arm. That is, at least one of the two clamping arms is a movable clamping arm 2 that can move relative to the bracket 1, and the other clamping arm can be a movable clamping arm 2 or a fixed clamping arm fixed relative to the bracket 1. As long as one clamping arm can move, the clamping height of the clamping assembly can be adjusted. Preferably, both clamping arms are movable clamping arms 2, so that the clamping space of the clamping assembly can have a larger adjustment range. The front side is explained with an embodiment in which both clamping arms are movable clamping arms 2. The two movable clamping arms 2 are correspondingly installed in the guide groove and are located between the bracket body 11 and the cover plate 12, and are used to reciprocate along the guide direction of the guide groove. The movable clamping arm 2 includes a connecting arm and a clamping portion 21 that are connected. The clamping portion 21 is protruding from the surface of the connecting arm and is located outside the guide groove, and is used to clamp the electronic equipment. That is, the clamping portion 21 extends outward along the side wall surface of the connecting arm close to the cover plate 12 to form a convex structure. The connecting arm includes a sliding portion 23 and a fixed portion 22 that are connected and arranged, and the two ends of the fixed portion 22 are respectively connected to the sliding portion 23 and the clamping portion 21 (the connection here refers to abutment, which can be an integrally formed structure), the width of the sliding portion 23 is set corresponding to the width of the second notch portion 112, and the width of the fixed portion 22 is set corresponding to the width of the first notch portion 111. That is, the width of the fixed portion 22 is smaller than the width of the sliding portion 23, and the width definition here is the same as the width definition of the guide groove. The fixed portion 22 can move in the guide space formed by the first notch portion 111 at both ends of the bracket 1, and the sliding portion 23 can move in the guide space formed by the second notch portion 112. The clamping portion 21 is located outside the guide groove. When the two movable clamping arms 2 move in a direction close to each other, the clamping portion 21 stops at the edge of the cover plate 12. The press-locking assembly 3 is used to abut or separate from the outer wall of the fixed portion 22. In order to reduce the overall weight of the clamping assembly, a through hole can be provided in the middle of the fixing portion 22. For example, in this embodiment, a waist-shaped through hole is provided in the middle of the fixing portion 22. In order to better protect the electronic device and reduce the wear of the electronic device during clamping, a contact portion (not shown) can be provided on the clamping surface of the clamping portion 21. The contact portion can be made of non-slip soft rubber or silicone.

[0047] Each movable clamp arm 2 is respectively provided with at least one set of push-locking components 3. Preferably, one set of push-locking components 3 is respectively provided on both sides of each movable clamp arm 2. Correspondingly, at least one outer side wall of the fixing portion 22 is provided with a groove 24 along the length direction, and the push-locking components 3 are used to abut or separate from the bottom of the groove 24. When the push-locking components 3 are respectively installed on both sides of the movable clamp arm 2, the two outer side walls of the fixing portion 22 are respectively provided with grooves 24, and each groove 24 is respectively provided with a push-locking component 3.

[0048] The press-lock assembly 3 is mounted on the bracket body 11, and is used to press and abut against the movable clamping arm 2 to fix the movable clamping arm 2 relative to the bracket 1 to clamp the electronic device; or to press and separate from the movable clamping arm 2 to allow the movable clamping arm 2 to move relative to the bracket 1, thereby adjusting the clamping distance between the two clamping arms, or releasing the clamped electronic device.

[0049] like Figure 5 and Figure 6 As shown, the principle of the push-locking assembly 3 is similar to the elastic push principle on a ballpoint pen. In this embodiment, each group of push-locking assemblies 3 includes a button cap 31, a locking member 33, a rotating member 36, an abutment member 37, a mounting member 32, a first elastic member 34 and a second elastic member 35.

[0050] The locking member 33 is used to guide the button cap 31, and the button cap 31 presses the rotating member 36 to lock the rotating member 36 at different positions of the locking member 33 to achieve the extension and retraction of the abutment member 37; the mounting member 32 is used to fix the pressing and locking assembly 3 on the bracket 1; the abutment member 37 is used to abut or separate from the movable clamp arm 2.

[0051] An inwardly recessed cavity 362 is provided at one end of the rotating member 36 away from the locking member 33, and the first elastic member 34 is installed in the cavity 362 of the rotating member 36. The end of the first elastic member 34 away from the button cap 31 is fixedly connected to the abutment member 37; the second elastic member 35 is sleeved on the end of the rotating member 36 away from the locking member 33.

[0052] Specifically, the ends of the key cap 31 and the rotating member 36 in this embodiment that are close to each other are inserted into the locking member 33 from the two ends of the locking member 33, and the locking member 33 is provided with a limiting groove 331 at one end close to the key cap 31, and the key cap 31 is correspondingly provided with a guide block 311, which is inserted into the limiting groove 331, so that the key cap 31 can only reciprocate along the length direction of the limiting groove 331, and there is no relative rotation between it and the locking member 33. The locking member 33 is alternately provided with a plurality of first stopping grooves 332 and second stopping grooves 333 at one end close to the rotating member 36, and the length of the first stopping groove 332 is greater than the length of the second stopping groove 333. A stop block 361 is provided at one end of the rotating member 36 close to the locking member 33. The number of the stop blocks 361 matches the total number of the first stop grooves 332 and the second stop grooves 333, and the width of the stop block 361 also matches the width of the first stop grooves 332 and the second stop grooves 333. The end of the stop block 361 and the bottom of the first stop grooves 332 and the second stop grooves 333 are inclined surfaces or arc-shaped surfaces. A circle of sawtooth-shaped protrusions 312 are provided along the circumferential direction at one end of the key cap 31 close to the rotating member 36, and the protrusions 312 are used to abut against the stop block 361 of the rotating member 36. The abutment 37 in this embodiment is made of soft rubber. The first elastic member 34 and the second elastic member 35 in this embodiment are springs respectively. A slide groove 363 is opened on the side wall of the cavity 362 of the rotating member 36 along the axial direction of the rotating member 36. The slide groove 363 connects the cavity 362 with the outside. A protruding slider 371 is correspondingly provided on the abutment 37. During installation, the slider 371 is placed in the slide groove 363 to make the first elastic member 34 always in a compressed state. In this way, it can be ensured that the first elastic member 34 always pushes the abutment 37. When there is no external force acting on the abutment 37, the abutment 37 can always protrude from the end of the rotating member 36, and the slider 371 stops at the end of the slide groove 363 to ensure that the abutment 37 will not slip off the rotating member 36. When it is necessary to press the key cap 31 to move the rotating member 36 toward the key cap 31 to loosen the movable clamping arm 2, the abutment member 37 will be pushed in the opposite direction by the movable clamping arm 2 due to the pressing force. At this time, the abutment member 37 can further compress the first elastic member 34 to move into the cavity 362, so that the rotating member 36 can complete the rotation action.

[0053] like Figure 7As shown, mounting holes 113 are respectively provided at positions corresponding to the bracket body 11 and the push-lock assembly 3, the mounting holes 113 are communicated with the guide grooves, a boss portion 114 is provided around the outer end of the mounting hole 113, a step is provided at the inner bottom, the locking member 33 is installed in the mounting hole 113, and the step is used to limit the locking member 33. The boss portion 114 in this embodiment is a cylindrical boss, and an external thread is provided on the boss, and the mounting member 32 of the push-lock assembly 3 is correspondingly provided with an internal thread, the mounting member 32 and the boss are detachably connected through threads, and the locking member 33 is limited in the mounting hole 113, so that the locking member 33 is fixed relative to the mounting hole 113.

[0054] The working process of the clamping assembly of this embodiment is as follows:

[0055] 1. To achieve clamping of electronic equipment: Press the key cap 31, the guide block 311 of the key cap 31 moves along the limit groove 331 of the fixed locking member 33 toward the direction close to the abutment member 37, and the serrated protrusion 312 of the key cap 31 pushes the stop block 361 of the rotating member 36 to withdraw from the first stop groove 332. The elastic force of the second elastic member 35 causes the rotating member 36 to rotate and enter the second stop groove 333, so that the abutment member 37 extends out and abuts against the bottom of the groove 24 of the movable clamping arm 2.

[0056] When the locking cam 35 is in the unlocking state, the locking cam 35 is in the unlocking state, and the locking cam 35 is in the unlocking state.

[0057] The clamping assembly of the embodiment of the present application can rotate the rotating member 36 by pressing the button cap 31, and the stop block 361 abuts against the first stop groove 332 and the second stop groove 333 in turn, so that the abutment member 37 switches between the extended and retracted states to clamp or loosen the movable clamp arm 2, which is very convenient to use. The force required to press the button cap 31 is small, and when the user needs to adjust the clamping height of the clamping assembly, it will be very easy and easy to adjust. It can be easily operated even with one hand, which is very convenient. In addition, the two clamping arms are not subject to the tension of the spring, and will not apply excessive force to the clamped electronic device, which can reduce damage and wear to the clamping device.

[0058] The embodiment of the present application also provides a handle, including a grip (not shown) and the above-mentioned clamping assembly, the bracket 1 of the clamping assembly is fixed on the grip, and the grip is the user's hand-held part, which is convenient for the user to hold. The handle can be a handle for clamping a portable infrared thermal imager and a mobile phone at the same time, or other handles for clamping electronic devices and having a grip. The handle can also include other functions, such as a battery compartment for power supply, etc.

[0059] The clamping assembly and handle provided in the embodiment of the present application are very convenient for adjusting the clamping height, save effort, and are easy to operate. They can be easily adjusted with one hand, and will not damage the electronic device due to excessive clamping force. The pressing and locking assembly of the clamping assembly has a simple structure and is not easy to damage. Even if the pressing and locking assembly is damaged, a certain pressing and locking assembly can be disassembled and replaced separately, which can effectively extend the overall service life of the clamping assembly.

[0060] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0061] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
