Description

Technical Field

[0001] This utility model relates to the field of tablet computer clamping technology, and in particular to a screwless quick clamping device. Background Technology

[0002] As tablet computers are used in vehicles, they require increasingly more expanded I / O and functions, leading to the emergence of various docking station products. In off-road and high-vibration environments, tablet computers need a clamping device that can be quickly installed and removed and is highly reliable.

[0003] However, in existing technologies, traditional clamping devices mainly use torsion spring structures and screw limiting structures. In high-vibration environments, the clamping force of the torsion spring is insufficient, and the tablet computer is prone to shaking and disengagement in the vibrating environment. Furthermore, when a single person takes out the tablet computer, they need to use one hand to hold down the button to keep the torsion spring stationary, and then use the other hand to take out the tablet computer, which is inconvenient to operate. In addition, this type of clamping device is not very versatile and cannot achieve the clamping function when the tablet computer does not have space to design positioning holes. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the clamping force of the torsion spring is insufficient in high vibration environments, and that the tablet computer is prone to shaking and disengagement in the vibration environment. Therefore, a screwless quick clamping device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screwless quick clamping device, comprising a cover, a middle cover fixedly connected to one side of the cover, an upper buckle slidably connected to the top of the middle cover, a connecting rod rotatably connected to one side of the upper buckle via a pin, a handle rotatably connected to the top of the connecting rod, a base rotatably connected to one end of the handle, the base being fixedly installed on the top of the middle cover, an upper rack fixedly connected to the bottom of the upper buckle, a gear meshing with the inner side of the upper rack, a left rack buckle meshing with the top of the gear, and a right rack buckle meshing with the bottom of the gear.

[0006] Preferably, the front shell is fixedly connected to one side of the middle cover by screws.

[0007] Preferably, a retaining plate is fixedly installed at the corner of the front shell, the end of the upper rack, the end of the left rack latch, and the end of the right rack latch.

[0008] Preferably, a tension spring is fixedly connected to the bottom of the upper rack, and the bottom of the tension spring is fixedly connected to one side of the middle cover.

[0009] Preferably, a button is fixedly installed on the top of the handle.

[0010] Preferably, both the left and right rack buckles are slidably connected between the middle cover and the front shell.

[0011] Preferably, the gear is rotatably mounted at the center point of the front housing.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up an upper rack, a left rack latch, and a right rack latch, the front shell, upper rack, left rack latch, and right rack latch will lock the tablet computer in actual use. The overall clamping adopts a plate structure, and the upper rack, left rack latch, and right rack latch are all driven by gears. Compared with spring structures and screw limiting structures, the overall structure can adapt to high vibration environments, and also has sufficient extension space, making it more versatile. Furthermore, the top of the upper rack is connected to a handle, which is confined inside the base, providing strong stability. During operation, one hand can be freed up simply by latching the handle inside the base, without having to keep the handle pressed down, making it convenient for one-handed operation.

[0014] 2. In this utility model, by setting a tension spring at the bottom of the upper rack, when the handle is released, the rebound of the tension spring can pull the upper rack to the bottom, thereby ensuring that the upper rack, the left rack buckle and the right rack buckle can stably hold the tablet computer, ensuring the stability of the entire device.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a screwless quick clamping device, including a cover 1, a middle cover 2 fixedly connected to one side of the cover 1, an upper buckle 7 slidably connected to the top of the middle cover 2, a connecting rod 11 rotatably connected to one side of the upper buckle 7 via a pin, a handle 3 rotatably connected to the top of the connecting rod 11, a base 13 rotatably connected to one end of the handle 3, the base 13 being fixedly installed on the top of the middle cover 2, an upper rack 8 fixedly connected to the bottom of the upper buckle 7, a gear 9 meshing with the inner side of the upper rack 8, a left rack buckle 6 meshing with the top of the gear 9, and a right rack buckle 5 meshing with the bottom of the gear 9.

[0024] The specific settings and functions of this embodiment are described in detail below. The hood 1 has multiple mounting holes inside for connection with the vehicle. In use, the hood 1 is fixed to the vehicle with bolts. The middle cover 2 is connected to the hood 1 with screws. The handle 3 has an L-shaped structure with hooks at its end and corners. One of the hooks is in contact with the protrusion on the edge of the connecting rod 11 when locked, which is used to ensure that the connecting rod 11 is vertical. At this time, the handle 3, the connecting rod 11 and the pivot of the connecting rod 11 are on a straight line, forming a dead point, which can withstand greater impact force without loosening. When it is necessary to clamp the tablet computer, the handle 3 is rotated to remove the hook at one end from the connecting rod 11, so that the hook at the corner is engaged in the through hole in the base 13, thereby fixing the handle 3 to the base 13.

[0025] As the handle 3 rotates, the connecting rod 11 pulls the upper latch 7 upward, causing the upper latch 7 to move upward towards the middle cover 2. During the movement of the upper latch 7, the upper rack 8 is driven. The upper rack 8, through the gear 9, simultaneously pushes the left rack latch 6 and the right rack latch 5. The left rack latch 6 and the right rack latch 5 are symmetrically distributed vertically. As the gear 9 rotates, it pushes the left rack latch 6 to the left and the right rack latch 5 to the right, thus revealing enough space to accommodate the tablet computer. After placing the tablet computer, the handle 3 can be rotated back to the horizontal position.

[0026] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, the front shell 4 is fixedly connected to one side of the middle cover 2 by screws. The corner of the front shell 4, the end of the upper rack 8, the end of the left rack buckle 6 and the end of the right rack buckle 5 are all fixedly installed with a clamping plate 14. The bottom of the upper rack 8 is fixedly connected with a tension spring 10. The bottom of the tension spring 10 is fixedly connected to the inner wall of the cover 1. The top of the handle 3 is fixedly installed with a button 12. The left rack buckle 6 and the right rack buckle 5 are slidably connected between the middle cover 2 and the front shell 4. The gear 9 is rotatably installed at the center point of the front shell 4.

[0027] The overall effect of this embodiment is that the front shell 4 is used to contact the tablet computer, while the presence of the latch 14 is mainly used to hold the edge of the tablet computer to improve the stability of the tablet computer. The tension spring 10 at the bottom of the upper rack 8 is fixedly connected to the middle cover 2. When the upper rack 8 moves upward, the tension spring 10 will be stretched. When the handle 3 is turned back, the tension spring 10 will rebound synchronously.

[0028] The usage and working principle of this device: When the cover 1 is fixed on the vehicle and locked, the hook at the end of the handle 3 is in contact with the protrusion at the edge of the connecting rod 11. At this time, the handle 3, the connecting rod 11 and the pivot of the connecting rod 11 are on a straight line, forming a dead point, which allows it to withstand greater impact force without loosening. When it is necessary to clamp the tablet computer, press down the button 12, and rotate the handle 3 to remove the hook at one end from the connecting rod 11, so that the hook at the corner is engaged in the through hole in the base 13, and the handle 3 is fixed on the base 13.

[0029] During the rotation of handle 3, the upper latch 7 is pulled up via connecting rod 11, causing the upper latch 7 to move upwards towards the middle cover 2. As the upper latch 7 moves, it drives the upper rack 8. The upper rack 8, through gear 9, simultaneously pushes the left rack latch 6 and the right rack latch 5. The left rack latch 6 moves to the left, and the right rack latch 5 moves to the right, exposing enough space to accommodate the tablet computer. After the tablet computer is placed, press button 12 again and rotate handle 3 back to the horizontal position. The tension spring 10 will rebound synchronously, ensuring that handle 3 remains in a horizontal position.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
