Description
Technical Field
[0001] This utility model relates to the field of electronic components, and in particular to a clamping device that is simple in structure, easy to operate, and provides uniform clamping force for different widths. Background Technology
[0002] With the advancement of technology and the continuous development of portable smart terminal products such as mobile phones and tablets, these products offer a wide variety of functions and are widely used in people's daily lives. People enjoy using their phones for taking photos, live streaming, or watching videos. However, due to the limitations of arm length, holding a smartphone handheld often doesn't yield satisfactory angles and compositions. Therefore, people now typically use selfie sticks or stands to hold the device in place for a better user experience. However, the different sizes of smart terminals and the different orientations of the same terminal will require different extension widths for the clamping device on the selfie stick or stand. To accommodate these varying width requirements, the extension range of the clamping device needs to be designed to be large. This makes the product more structurally complex, and in practice, insufficient elasticity often results in insufficient clamping force when holding a small width. Summary of the Invention
[0003] To address the aforementioned problems, the present invention aims to provide a clamping device that is simple in structure, easy to operate, and provides uniform clamping force for different widths.
[0004] This utility model is achieved through the following technical measures: a clamping device includes a main housing, two clamping arms are provided on both sides of the main housing, at least one slider is slidably disposed on the main housing, and at least one clamping arm is slidably disposed on the slider; the slider is movably locked onto the main housing by a locking structure, the locking structure is provided with an unlocking structure, and the slider is provided with a first elastic structure. When the slider is locked onto the main housing, the first elastic structure is elastically deformed; when the unlocking structure is unlocked, the slider slides outward from one side of the main housing under the action of the restoring force of the first elastic structure.
[0005] As a preferred embodiment, the bottom of the main housing is covered with a rear cover, and a button hole is provided on the main housing. The locking structure includes a second elastic structure disposed between the rear cover and the main housing. A button is provided at the movable end of the second elastic structure, and the top of the button is disposed in the button hole. A locking post is also provided below the button, which is movably locked onto the slider. Pressing the button inward causes the locking post to disengage from the slider and the second elastic structure to elastically deform. At this time, the slider slides outward from one side of the main housing under the action of the restoring force of the first elastic structure. Releasing the button resets the button under the action of the restoring force of the second elastic structure. Forcefully sliding the slider into the main housing causes the first elastic structure to elastically deform. When the slider returns to the corresponding position, the locking post below the button locks onto the slider, causing the slider to retract into the main housing or retract a certain length.
[0006] In a preferred embodiment, the slider is provided with a buckle hole corresponding to the buckle post. The buckle post extends from the bottom of the buckle hole into the buckle hole to lock onto the slider. When the button is pressed down, it causes the buckle post to move downward and disengage from the buckle hole. The upper end of the buckle post is set as an inclined surface in the direction of the slider sliding inward.
[0007] As a preferred embodiment, the rear cover extends outward and is provided with a retaining sleeve, the retaining sleeve having a locking nut on its external thread.
[0008] As a preferred embodiment, the back cover is provided with a sliding post pointing inward to the button hole, the button is slidably disposed at the upper end of the sliding post, and a compression spring is provided on the outer sleeve of the sliding post.
[0009] As a preferred embodiment, a first slider and a second slider are slidably disposed on both sides of the main housing, and the first elastic structure is disposed between the first slider and the second slider, or the first slider and the second slider are respectively disposed between the first elastic structure and the main housing.
[0010] As a preferred embodiment, the first elastic structure is a tension spring.
[0011] As a preferred embodiment, the clamping arm slidably disposed on the slider includes at least one pull rod slidably disposed on the slider. One end of the pull rod is fixed with a pull rod fixing block to prevent the pull rod from being pulled off the slider, and the other end of the pull rod extends vertically upward to provide a handle. The pull rod is sleeved with a compression spring.
[0012] As a preferred embodiment, each of the two clamping arms is provided with an upwardly extending handle, and the handle is provided with a handle hole.
[0013] As a preferred embodiment, the two handles are provided with handle silicone pads facing each other, and the handle silicone pads are provided with through holes corresponding to the handle holes.
[0014] This clamping device uses a slider that slides on the main housing, with the clamping arms slidably mounted on the slider. When the slider is retracted into the main housing, the extension and retraction of the two clamping arms stretches the second elastic structure (such as a spring) between them to clamp the smart terminal product. When the smart terminal product is placed horizontally or is wider, a conveniently operated component, such as a button, is used as the unlocking mechanism for the slider. Under the elastic restoring force of the first elastic structure (such as a tension spring), the slider slides outward from one side of the main housing, thereby increasing the initial width between the two clamping arms. This allows for the clamping of wider products. The clamping force of the product comes from the tensile force of the deformation of the second elastic structure (such as a spring). The clamping force is basically constant for different products or widths, which facilitates the elasticity design of the clamping device and ensures a relatively stable clamping force.

[0019] Figure 5 This is an exploded view of the clamping device according to an embodiment of the present invention. Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.
[0021] Please refer to the attached drawing for a clamping device according to this embodiment. Figures 1 to 5 The system includes a main housing 300, with two clamping arms 100 on both sides. A slider 200 is slidably mounted on the main housing 300. In this embodiment, two sliders 200 are slidably mounted on the main housing 300, and the two clamping arms 100 are slidably mounted on the sliders 200 respectively. In other embodiments, such as in installation positions where one side cannot slide, a slider can be mounted on only one side, with the clamping arm on the other side fixedly mounted on the main housing. The slider 200 is movably locked onto the main housing 300 by a locking structure, which includes an unlocking mechanism. The slider 200 has a first elastic structure. When the slider 200 is locked onto the main housing 300, the first elastic structure elastically deforms. When the unlocking mechanism unlocks, the slider slides outward from one side of the main housing 300 under the restoring force of the first elastic structure.
[0022] This clamping device uses a slider 200 that slides on the main housing 300, and clamping arms 100 are slidably mounted on the slider 200. When the slider 200 is retracted into the main housing 300, the extension and retraction of the two clamping arms 100 stretches the second elastic structure (such as a spring) between them to clamp the smart terminal product. When the smart terminal product is placed horizontally or the product is wider, only a conveniently operated component such as a button is needed as the unlocking structure of the slider 200. Under the elastic restoring force of the first elastic structure (such as a tension spring), the slider 200 slides outward from one side of the main housing 300, thereby increasing the initial width between the two clamping arms 100, thus enabling the clamping of wider products. The clamping force of the product comes from the tensile force of the deformation of the second elastic structure (such as a spring). The clamping force is basically constant for different products or widths, which facilitates the elasticity design of the clamping device and makes the clamping force relatively stable.
[0023] In one embodiment of the clamping device, please refer to Figure 1-5 Based on the preceding technical solution, a further embodiment can be provided: a rear cover 600 is provided at the bottom of the main housing 300; a button hole 301 is provided on the main housing 300; a sliding post 601 pointing inwards from the rear cover 600 is provided towards the button hole 301; the button is slidably disposed on the upper end of the sliding post; a compression spring 402 is sleeved on the sliding post; a button 400 is disposed on the movable end of the compression spring 402; the top of the button 400 is disposed within the button hole 301; and a latching post 401 that is movably locked onto the slider 200 is also provided below the button 301; the button 400 is flush with or slightly below the upper surface of the main housing 300; when clamping a horizontal or wider product, pressing the button 400 inwards causes the latching post 401 to engage. The slider 200 is disengaged, causing the compression spring 402 to deform elastically under pressure. At this time, the tension spring 202, under the action of restoring force, causes the slider 200 to slide outward from one side of the main housing 300. The button 400 is released, and under the action of the restoring force of the compression spring 402, the button 400 returns to its original position. When it is necessary to retract the slider 200, the slider 200 is slid inward into the main housing 300 with force, causing the tension spring 202 to stretch and deform elastically. When the slider 200 returns to the corresponding position, the latch 401 below the button 400 locks onto the slider 200, causing the slider 200 to retract into the main housing. In other embodiments, the latch 401 can also be locked at different positions on the slider 200, so that the slider 200 slides out of the main housing 300 by different lengths, in order to more precisely adjust the clamping width.
[0024] In one embodiment of the clamping device, please refer to Figure 5Based on the aforementioned technical solution, the slider 200 may also have a corresponding buckle hole 201 for the buckle post 401 (in other embodiments, there may be multiple buckle holes, thereby allowing the slider 200 to slide out of the main housing 300 by different lengths). The buckle post 401 extends upward from below into the buckle hole 201 to lock onto the slider 200. When the button 400 is pressed downward, it causes the buckle post 401 to move downward and disengage from the buckle hole 201. The upper end of the buckle post 401 is set as an inclined surface along the direction in which the slider 200 slides inward. Thus, when the slider 200 retracts, the buckle hole 201 squeezes the inclined surface of the buckle post 401 downward, causing the button 400 to move the buckle post 401 into the buckle hole 201.
[0025] In one embodiment of the clamping device, please refer to Figure 1-5 In order to fix the clamping device, based on the above technical solution, the rear cover 600 can also be provided with a sleeve 601 extending outward. The sleeve 601 is provided with a locking nut 500 on its external thread. After the universal ball and other components are put into the sleeve 601, the locking nut 500 is locked.
[0026] In one embodiment of the clamping device, please refer to Figure 1-5 Based on the preceding technical solution, a more specific embodiment could be a clamping arm 100 slidably mounted on a slider 200, comprising two parallel pull rods 102 slidably mounted on the slider. One end of each pull rod 102 is fixed with a pull rod fixing block 105 to prevent it from being pulled off the slider 200. The other end of each pull rod 102 extends vertically upwards with a handle 103. A compression spring 104 is fitted over each pull rod 102. Smart terminal products (such as mobile phones) are clamped between the handles 103, and the restoring force of the compression spring 104 is used to hold the smart terminal product in place.
[0027] In one embodiment of the clamping device, please refer to Figure 1-5 To facilitate the opening of the clamping arm 100, based on the previous technical solution, the handle 103 can also be provided with a handle hole.
[0028] In one embodiment of the clamping device, please refer to Figure 1-5 To prevent the clamping force of the clamping arm 100 from scratching the surface of the smart terminal product, based on the above technical solution, the two handles 103 are provided with handle silicone pads 101 facing each other, and the handle silicone pads 101 are provided with through holes corresponding to the handle holes.
[0029] The above describes the clamping device of this utility model to help understand this utility model. However, the implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of this utility model shall be considered equivalent substitutions and shall be included within the protection scope of this utility model.
