[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The purpose of the present invention / utility model is to solve the problem of quick opening and locking of handheld devices. The frame ensures the limitation of the left and right sides, the back and the bottom, the front baffle ensures the limitation of the front lower end, and the frame pressure plate ensures the limitation of the top surface and the front upper end; the buckle is fixed to the frame to lock the frame and the frame pressure plate together; the frame pressure plate has a hook, and when the buckle is locked, it is placed on the hook and then pressed down to lock it.

[0035] The frame is constructed of aluminum alloy, copper- and nickel-plated after processing. The frame pressure plate is constructed of 316 stainless steel, ensuring consistent strength and rigidity, stable performance, and a long service life. It also meets the requirements for salt spray, damp heat, and mildew resistance testing. The entire quick-release locking mechanism is vibration- and shock-resistant, meeting the vibration and shock requirements specified in GJB 367A-2001\3.10.3.1 and GJB 367A-2001\3.10.3.2.

[0036] like Figure 1 As shown, a quick locking device (abbreviated as quick locking device) has a maximum external dimension of 157 mm × 102 mm × 52 mm. The quick locking device is composed of the following components: a frame 1, a frame pressure plate 2, a front baffle 3, an axle pin 4, and a buckle 5.

[0037] The design of the rack 1 must be based on the shape of the handheld device to be locked. The periphery of the handheld device must fit snugly after installation, with appropriate clearances. If external power is required, the power connection must be considered. Silicone rubber pads 6 must be applied to each surface of the rack 1 to provide cushioning and surface protection. A pin hole 7 for mounting the rack pressure plate is designed on the upper left side of the rack 1, and a threaded hole 8 for mounting the buckle is designed on the right side of the rack 1. Screw holes 9 are designed on the back and bottom of the rack 1 to secure the quick locking device to the entire device. Figure 2 shown.

[0038] When designing the rack pressure plate 2, the top interface of the handheld device must be considered to prevent the interface from interfering with the rack pressure plate. The rack pressure plate 2 is subjected to the downward pressure of the buckle, so stainless steel or 45 steel is selected as the material; the middle part of the left side of the rack pressure plate 2 has a protrusion 10, which is installed with the rack 1, and the middle of the protrusion is a through hole for the installation pin. The front of the rack pressure plate 2 is turned down to limit the upper end of the front of the handheld device; the right side of the rack pressure plate 2 has a riveted hook 11, which is hung on it when the buckle is locked; the inside of the rack pressure plate 2 has an irregular shaped sink 12, which is affixed with a silicone rubber pad. The appearance of the rack pressure plate 2 is as follows: Figure 3 shown.

[0039] The front baffle 3 is made of aluminum alloy or stainless steel. There are four screw countersunk holes 13 on both sides for fixing to the frame 1. Silicone rubber pads are attached to the inside. The thickness of the front baffle can be adjusted according to the impact and vibration requirements. You can even eliminate the front baffle and make the front baffle 3 and the frame 1 form a whole. Figure 4 shown.

[0040] The shaft pin 4 is made of stainless steel, with a slot on the top and a thread on the end. Figure 5 shown.

[0041] Buckle 5 is made of 08F steel plate, which is processed and assembled with white zinc plating. You can also purchase suitable buckles on the market. The appearance is as follows: Figure 6 shown.

[0042] The quick-action locking mechanism works based on the close coordination and interaction between various components, aiming to provide reliable and quick locking and securing functions for handheld devices, ensuring the stability and protection of the device during use. The specific working principle is divided into the following steps:

[0043] 1. Equipment loading and securing

[0044] The rack 1 is the core structure of the quick-locking device. Its size and shape are customized according to the appearance of the handheld device to ensure that the device can be accurately placed in the rack. A silicone rubber pad 6 is affixed to the inside of the rack 1 to cushion the pressure of the handheld device during installation, protect the device surface from scratches or damage, and provide shock absorption. After the device is installed in the rack, the rack pressure plate 2 is responsible for pressing the device from the top to ensure that the device does not shake inside the rack. The left side of the rack pressure plate is connected to the rack 1 via a pin 4, allowing the pressure plate to rotate around the pin to facilitate the installation and removal of the device. The buckle 5 on the right side is used to lock the rack pressure plate in place.

[0045] 2. Buckle locking mechanism

[0046] After the device is installed in rack 1, rack plate 2 is pressed down onto the top of the device and secured with a latch 5 that connects to a threaded hole 8 on the right side of the rack. One end of latch 5 is secured to threaded hole 8 in rack 1, while the other end connects to a hook on the right side of rack plate 2 via a rivet hook 11. When the latch is tightened, it generates a downward force, firmly pressing rack plate 2 against the device, locking it in place. This latch-type design allows for quick operation, securing the device with a simple snap action.

[0047] 3. Multi-layer protection and vibration protection

[0048] To further enhance device protection, silicone rubber pads 6 are affixed to the interior of the frame 1, frame pressure plate 2, and front bezel 3. These pads not only provide physical cushioning to prevent damage from external impact, but also absorb some of the vibration generated during use, ensuring stability in high-vibration environments. Furthermore, the front bezel 3 is constructed from aluminum alloy or stainless steel, and its thickness can be adjusted to meet specific device requirements. The front bezel can even be eliminated, allowing the frame 1 and front bezel to form a single unit, enhancing the overall structural strength and stability.

[0049] 4. Equipment operation and connection after locking

[0050] The design of the frame 1 takes into account the external power connection required by handheld devices. Therefore, the shape of the frame 1 ensures a snug fit around the handheld device when inserted, while also leaving ample space for connecting power cables or other external interfaces. The frame's retaining plate 2 is also specially designed to avoid interference with the top connector of the handheld device, ensuring that the device's interface functionality is not affected when locked.

[0051] 5. Ease of installation and fixing

[0052] To facilitate installation and securement of the entire device, screw holes 9 are designed on the rear and bottom surfaces of the frame 1. These holes allow the quick-locking device to be secured to the entire device, ensuring the entire locking system can be stably mounted on the work platform or equipment. Furthermore, the axle pin 4 is designed with a threaded design and a slotted end, making it easy for the user to use tools to adjust or replace the frame pressure plate when installing or removing it.

[0053] To sum up, the quick locking device forms a stable, efficient and easy-to-operate locking system through the cooperation of the frame, pressure plate, buckle and other structures. It can ensure the stability of the handheld device during use, while providing multiple protections for the device. It is suitable for work scenarios that require quick installation and locking.

[0054] The emergence of the quick locking device solves the problem that handheld devices require firm fixation and quick locking and opening. It has the advantages of simple and convenient operation, novel appearance, simplicity, durability, and elegant appearance. Figure 7 This is an application example where a handheld device is used as part of a certain type of communication equipment and is fixed to the entire device through a quick locking device. When the quick locking device is used alone and needs to be installed on a test platform or vehicle, the rack can be modified to make the quick locking device easier to install, such as Figure 8 shown.

[0055] The quick-locking device is suitable for handheld devices, but its application is not limited to handheld devices. Those skilled in the art may make various modifications and variations to the present invention / utility model without departing from the spirit and scope of the present invention, such as changing the size, shape, or material of the quick-locking device; changing the shape, material, or thickness of the silicone rubber pad; or adding or removing certain parts. Thus, if such modifications and variations fall within the scope of the claims of the present invention / utility model and their equivalents, the present invention / utility model is intended to encompass such modifications and variations.

[0056] The working principle of this quick locking device can be divided into four main steps, namely the installation of the handheld device, the positioning of the rack pressure plate, the buckle locking, and the fixing and protection. The following is a detailed description of the working principle:

[0057] Mounting the Handheld Device to the Rack: The core of the quick-lock mechanism is the rack 1, custom-designed to the handheld device's dimensions to ensure precise installation. A silicone rubber pad 6 is affixed to the inner surface of the rack 1, providing cushioning and protection for the handheld device, preventing surface damage during the locking process. Furthermore, screw holes 9 are designed at the rear and bottom of the rack 1 to facilitate securing the rack to the complete device and ensure the quick-lock mechanism remains stable during operation.

[0058] Positioning and protecting the rack pressure plate: After the handheld device is mounted on rack 1, rack pressure plate 2 is attached to rack 1 via pivot pin 4. Rack pressure plate 2 features a raised structure 10 that matches the structure of rack 1 and prevents the handheld device from moving during installation. The front end of rack pressure plate 2 folds downward to hold the front end of the device in place. Silicone rubber pads 12 are affixed to the inside of the rack pressure plate to further cushion and protect the top of the device. Rack pressure plate 2 is constructed of stainless steel or 45 steel to ensure sufficient strength under load.

[0059] The buckle's locking function: Buckle 5 is installed on the right side of the frame 1 and secured via threaded hole 8. Once the handheld device is in place, buckle 5 can be pressed down to engage with the rivet hook 11 on the right side of the frame's pressure plate 2, locking the device. Buckle 5 applies downward pressure to secure the handheld device within the frame, achieving a quick, secure lock. The buckle is made of 08F steel plate with a white zinc coating for enhanced corrosion resistance and durability.

[0060] Synergistically securing and protecting: Front bezel 3 further strengthens the overall structure of the locking mechanism. It is secured to the chassis 1 via four screw countersunk holes 13. A silicone rubber pad is also applied to the inside of the bezel to protect the handheld device from shock and vibration damage during use. The thickness of the front bezel can be adjusted to suit the device's vibration requirements. It can even be eliminated, integrating the front bezel directly into the chassis 1 to simplify the design and increase device stability.

[0061] Through the cooperation of these designs and components, the quick locking device can quickly and firmly fix the handheld device in the desired position, ensuring that the device maintains a reliable operating state when it is inconvenient to operate or does not require manual operation.

[0062] The reliability provided by this utility model has also passed the rigorous shock and vibration test.

[0063] The handheld platform was installed in a quick-release locking device and then secured to the impact table. A half-sine wave pulse with a peak acceleration of 300m / s² (and a pulse width of 6ms) was applied, with two impacts in each axis, for a total of six impacts, as shown in Table 1. After the test, the handheld platform and quick-release locking device showed no looseness or deformation, and no mechanical damage.

[0064] Waveform Half sine Peak acceleration 100g Pulse width 6ms Number of impacts 6 times in total

[0065] Continue installing the handheld platform into the quick-release locking device and then secure it to the vibration table. Use a sinusoidal sweep vibration, adjusting the frequency according to Table 2. Sweep the platform every 15 minutes, for a total of two sweeps of 30 minutes. After the test, the handheld platform and quick-release locking device appear intact, showing no signs of looseness or deformation.
