DETAILED DESCRIPTION

[0027] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0029] The multifunctional secondary screen bracket provided by the present invention is applied to cash register equipment. Specifically, it can be used to support the main screen, secondary screen, POS machine, printer and other electronic equipment of the cash register equipment. Cash register equipment is generally arranged on both sides of the exit channel of the supermarket. In order to facilitate the guidance of customers, the exit channel is generally narrow. However, in order to adjust the installation angle of the above-mentioned various electronic equipment, the installation bracket of the above-mentioned equipment is generally provided with multiple movable joints, which causes it to occupy a large space; in addition, the existing installation bracket has a complex structure, which is not convenient for the installation and disassembly of the above-mentioned electronic equipment, and generally requires multiple staff members to cooperate with each other to realize the installation of the bracket. To this end, the present invention provides a multifunctional secondary screen bracket, which can realize the rapid installation of the above-mentioned electronic equipment by using a self-locking mechanism and an unlocking mechanism, and the bracket provided by the present invention can be adapted to various support units, and can support a variety of electronic equipment such as the main screen, secondary screen, POS machine, printer, etc.; the bracket provided by the present invention has a compact structure, occupies a small space, and has strong adaptability to the site.

[0030] See also Figure 1-Figure 8As shown, the technical solution of the present invention is described in detail below in conjunction with specific embodiments:

[0031] See also Figure 1-Figure 4 As shown, the multifunctional secondary screen bracket provided by the embodiment of the present invention includes a support rod 10 and a support sleeve 20; the support rod 10 is vertically arranged, and a mounting portion for connecting to a desktop is provided at the bottom of the support rod 10; the support sleeve 20 is sleeved on the support rod 10, and the support sleeve includes a self-locking mechanism and an unlocking mechanism, and the self-locking mechanism is configured to limit the movement of the support sleeve to prevent the support sleeve from sliding downward relative to the support rod 10; the unlocking mechanism is configured to release the restriction of the self-locking mechanism on the support sleeve under the action of an external force, so that the support sleeve 20 can slide downward relative to the support rod 10; an extension rod 211 is provided on the outer wall of the support sleeve 20, and a connecting portion for connecting a support unit is provided at the end of the extension rod 211, and the support unit is a screen support unit 30, a POS machine support unit or a printer support unit.

[0032] See also Figure 1 As shown, when installing electronic devices such as displays, the support sleeve 20 can be first connected to the electronic device, the support rod 10 can be installed on the cashier counter, and then the operator can put the support sleeve 20 on the support rod 10. During this process, the operator triggers the unlocking mechanism to release the self-locking mechanism from limiting the movement of the support sleeve 20. At this time, the support sleeve 20 can slide freely up and down along the support rod 10. After the operator adjusts the support sleeve 20 to a suitable height, the unlocking mechanism is released. At this time, the self-locking mechanism can prevent the support sleeve 20 from moving downward, thereby keeping the support sleeve 20 and the electronic device connected to the support sleeve 20 at the current height. In the present invention, the self-locking mechanism only limits the downward movement of the support sleeve 20. Therefore, when it is necessary to remove or lift the electronic device, the operator only needs to directly apply an upward force to the electronic device or the support sleeve 20, which is simple and convenient to operate.

[0033] See also Figure 4 As shown, in an optional embodiment of the present invention, the support sleeve 20 includes a core 22 and a rotating part 21, the core 22 is accommodated in the rotating part 21, the rotating part 21 is rotatably connected to the core 22, and the self-locking mechanism is installed on the core 22. It should be understood that since the self-locking mechanism is installed on the core 22, and the core 22 is rotatably connected to the rotating part 21, even after the self-locking mechanism clamps the support rod 10, the rotating part 21 can still rotate relative to the support rod 10, so the support sleeve 20 itself can serve as a left and right movable joint. Taking the display mounting structure as an example, only one upper and lower movable joint needs to be set on the display support unit to achieve the adjustment of the display pitch angle and left and right tilt angle. While ensuring the adjustment function, the present invention saves a section of movable joints and improves space utilization.

[0034] See also Figure 4 , Figure 5 , Figure 7 As shown, in an optional embodiment of the present invention, the self-locking mechanism includes a lifting bracket 23 and a clip 24, the lifting bracket 23 is movably connected to the core 22 along the axial direction of the support rod 10, the clip 24 is movably connected to the lifting bracket 23 along the radial direction of the support rod 10, one side of the clip 24 is in contact with the support rod 10, the other side of the clip 24 is provided with a first inclined wedge surface 241, and the inner wall of the core 22 is provided with a second inclined wedge surface 221. When the lifting bracket 23 has a tendency to move upward relative to the core 22, the clip 24 can increase the interaction force with the support rod 10 under the action of the first inclined wedge surface 241 and the second inclined wedge surface 221. A first elastic element 25 is provided between the lifting bracket 23 and the core 22 or the rotating part 21, and the first elastic element 25 is installed so that its elastic force can drive the lifting bracket 23 to move upward relative to the core 22.

[0035] The working principle of the self-locking mechanism is as follows: Figure 4 For example, the rotating part 21 and the core 22 tend to move downward under the action of their own gravity and the gravity of the electronic device, and there is a vertical friction between the clip 24 and the support rod 10, so the clip 24 and the lifting bracket 23 move upward relative to the core 22. At this time, the clip 24 further clamps the support rod 10 under the action of the first inclined wedge surface 241 and the second inclined wedge surface 221, which further increases the friction. The greater the downward movement of the core 22, the greater the friction between the clip 24 and the support rod 10, so that the support sleeve 20 can be maintained at the current height. The first elastic element 25 can be a compression spring. Even if the core 22 has no tendency to move downward relative to the lifting bracket 23, the compression spring can ensure that the clip 24 fits the support rod 10, so as to provide the required initial friction for the self-locking mechanism.

[0036] See also Figure 4 , Figure 5 , Figure 7As shown, in an optional embodiment of the present invention, the unlocking mechanism includes a floating plate 26 and a driving plate 27, the floating plate 26 is slidably arranged relative to the rotating part 21 along the axial direction of the support rod 10, and the floating plate 26 and the rotating part 21 are synchronously rotated, the floating plate 26 and the core body 22 are relatively rotated, and the floating plate 26 is in contact with the upper end of the lifting bracket 23; the driving plate 27 is connected to the rotating part 21 for relative rotation, the upper end of the floating plate 26 is provided with a third inclined wedge surface 261, and the lower end of the driving plate 27 is provided with a fourth inclined wedge surface 271. When the driving plate 27 rotates relative to the floating plate 26, the floating plate 26 and the lifting bracket 23 can be driven downward relative to the core body 22 under the action of the third inclined wedge surface 261 and the fourth inclined wedge surface 271. In a specific embodiment, a limiting groove 262 can be set on the side of the floating plate 26, and a convex ridge 217 can be set on the inner wall of the rotating part 21. The limiting groove 262 cooperates with the convex ridge 217 to realize the floating plate 26 sliding up and down while preventing the floating plate 26 from rotating relative to the rotating part 21, thereby ensuring that the third inclined wedge surface 261 and the fourth inclined wedge surface 271 can always be in a mutually cooperating position during the rotation of the rotating part 21.

[0037] See also Figure 6-Figure 8 As shown, in an optional embodiment of the present invention, the unlocking mechanism further includes a trigger portion 281, which is exposed on the surface of the support sleeve 20. A transmission mechanism is provided between the trigger portion 281 and the drive disk 27. The transmission mechanism is configured to drive the drive disk 27 to rotate when the trigger portion 281 is subjected to an external force. The transmission mechanism includes a lever 28, which is hinged to the inside of the extension rod 211. The trigger portion 281 includes a pressing handle provided at one end of the lever 28, and a waist-shaped hole 282 is provided at the other end of the lever 28. A guide pin 272 is provided on the drive disk 27, and the guide pin 272 is slidably pivoted with the waist-shaped hole 282. A second elastic element 29 is provided between the lever 28 and the extension rod 211. The second elastic element 29 is configured to drive the lever 28 to reset when the external force on the trigger portion 281 is eliminated. The second elastic element 29 may be a torsion spring.

[0038] The specific working principle of the unlocking mechanism is as follows: Figure 7 , Figure 8 For example, when the above-mentioned self-locking needs to be released, the operator holds the extension rod 211 with one hand and presses the trigger part 281. The trigger part 281 drives the driving disk 27 to rotate through the lever 28. At this time, the third inclined wedge surface 261 and the fourth inclined wedge surface 271 are gradually misaligned, thereby pushing the floating disk 26 downward. The floating disk 26 squeezes the lifting bracket 23 downward, thereby keeping the lifting bracket 23 in a low position. At this time, a gap will be formed between the first inclined wedge surface 241 and the second inclined wedge surface 221, so that the clip 24 cannot clamp the support rod 10, thereby realizing the unlocking of the self-locking mechanism.

[0039] See also Figure 5 As shown, in an optional embodiment of the present invention, the connecting portion includes a tapered external thread 212 provided at the end of the extension rod 211, and a pressure cap 214 screwed to the tapered external thread 212, the extension rod 211 is a hollow structure, and a gap 213 is provided at the end of the extension rod 211 corresponding to the tapered external thread 212, and a plurality of gaps 213 are arranged at intervals along the circumference of the extension rod 211. In a specific embodiment, in order to facilitate manufacturing, the rotating portion 21 can be arranged as two half-shell structures, and the upper end and the lower end of the half shell are connected by an upper cover 215 and a lower cover 216, respectively.

[0040] See also Figure 1 As shown, the mounting portion includes a C-shaped groove 11 for accommodating the edge of the desktop, the support rod 10 is fixedly connected to the top wall of the C-shaped groove 11, and a fixing screw 12 for pressing the bottom wall of the desktop is provided on the bottom wall of the C-shaped groove 11.

[0041] In summary, the multifunctional sub-screen bracket provided by the present invention utilizes a self-locking mechanism and an unlocking mechanism to realize the rapid installation of the above-mentioned electronic equipment, and the bracket provided by the present invention can be adapted to various support units, and can support a variety of electronic devices such as the main screen, sub-screen, POS machine, printer, etc.; the bracket provided by the present invention has a compact structure, occupies a small space, and has strong adaptability to the site; because the self-locking mechanism is installed on the core body 22, and the core body 22 is rotatably connected to the rotating part 21, even after the self-locking mechanism clamps the support rod 10, the rotating part 21 can still rotate relative to the support rod 10, so the support sleeve 20 itself can be used as a left and right movable joint. Taking the display installation structure as an example, only an upper and lower movable joint needs to be set on the display support unit to realize the adjustment of the display pitch angle and left and right tilt angles. While ensuring the adjustment function, the present invention eliminates a section of movable joints and improves space utilization.
