Quick locking device suitable for display support

Technical Field

The utility model belongs to the technical field of the attached manufacturing technique of display and specifically relates to a quick locking device suitable for display support.

Background

With the development of science and technology, flat panel displays are applied in large scale in production and life. In order to meet the requirements of consumers on the angle or the direction of the display, display supports of various models and specifications are developed on the market, and the use experience of people is greatly improved. In some special cases, the display needs to be fixed to the profile, and the mainstream fixing methods in the prior art mainly include the following two methods: 1) the hook type is that the hook is directly arranged on the display base plate, and in actual operation, the hook is directly hung on the section bar. The scheme has poor connection stability, and the safety of the display cannot be ensured. A common solution is to add a binding band or a clamping tool between the base plate of the display and the profile, so that the operation process is inevitably complicated; 2) the fastener is connected. The scheme inevitably needs to provide through holes or threaded holes on the section bar. Therefore, on one hand, when the display needs to be moved integrally, the fastener needs to be disassembled integrally, so that the operation is very inconvenient, and time and labor are consumed; on the other hand, for safety reasons, it is strictly forbidden to perforate the profile in some cases, thus limiting the applicability of the display stand. Thus, a skilled person is urgently needed to solve the above problems.

Detailed Description

In the description of the present invention, it should be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The following detailed description is made in conjunction with the specific embodiments, and fig. 1 shows the installation schematic diagram of the middle quick locking device and the section bar of the present invention, so that the quick locking device is clamped on the upper and lower edges of the section bar, thereby fixing the display bracket. Fig. 2 shows a schematic structural diagram of the fast locking device for a display stand of the present invention, which mainly comprises a locking body 1, a cover plate 2, a locking mechanism 3, and so on. Wherein a fixing post mount 11 (shown in fig. 4) is provided on the right side surface of the lock body 1. The left side of the locking body 1 is recessed to the right side to form a sunken groove 12. The cover plate 2 is buckled with the sinking groove 12 to form a cavity structure for accommodating the locking mechanism 3. The locking mechanism 3 comprises a positive locking member 31 sliding along the sinking recess 12 and a power part 32. The top of the cover plate 2 is provided with a clamping flange 21, and correspondingly, the active locking member 31 is provided with a claw 311. A pawl slide 23 is provided on the cover 2 for the pawl 311 to pass over the cover 2 (as shown in fig. 3 and 5). The power portion 32 drives the pawls 311 to move toward/away from the chuck flange 21. In the actual operation process, the rapid section bar clamping device and the section bar are locked by the clamping flanging 21 and the clamping claw 311 which move oppositely, so that the display bracket is fixed with high reliability, and the looseness of the display bracket in the later period is effectively prevented. More importantly, the mounting holes do not need to be formed in the sectional materials, and the application range of the display support is effectively expanded.

It should be noted that, in order to make the quick locking device have good usability, the clamping flange 21 may extend along the top of the cover plate 2, and the number of the claws 311 is set to 2, and the claws are respectively arranged in close proximity to the front and rear side walls of the sinking groove 12.

As a further refinement of the structure of the power unit 32, it can be designed as follows: the power portion 32 includes a force bearing seat 321 and a screw 322. Wherein, the force bearing seat 321 is fixed on the bottom wall of the sinking groove 12. The lower end of the screw rod 322 is fixed on the bearing seat 321, and the upper end thereof passes through the top wall of the locking body 1. The active locking member 31 is provided with a threaded through hole matched with the screw rod 322. By turning the screw 322, the jaw 311 can be moved along the height direction of the sinking groove 12, thereby realizing the clamping and releasing of the quick clamping device relative to the section bar.

In the experiment of small-batch trial products, it is found that the top wall of the locking body 1 and the portion passing through the screw rod 322 are easily worn or even damaged, and therefore, in order to solve the technical problem, the top wall of the locking body 1 may be provided with the reinforcing boss 13, and a through hole (as shown in fig. 4) is formed in the reinforcing boss for the screw rod 322 to pass through, so as to reduce the wear rate of the top wall of the locking body 1 by the screw rod 322.

The power unit 32 is further provided with a manual knob 323 fixed to the upper end of the screw 322. A plurality of strip-shaped anti-slip protrusions (not shown in the figure) are uniformly distributed in the circumferential direction on the side wall of the manual knob 323. Thus, in the actual operation process, the operator can directly rotate the handle without using tools such as a wrench or a pliers.

In addition, when the trouble takes place, in order to facilitate setting up power portion 32 inside locking body 1 and overhaul, as the further optimization of above-mentioned quick locking device, preferably with detachable mode being connected between apron 2 and the locking body 1, the concrete embodiment is: a plurality of connecting columns 14 are fixed on the bottom wall of the sinking groove 12, and correspondingly, a plurality of screw through holes 22 corresponding to the positions of the connecting columns 14 are arranged on the cover plate 2. As a further optimization, for the single connecting column 14, reinforcing ribs 15 may be disposed along the side walls thereof, and at least one reinforcing rib 15 is connected to the side walls of the sinking groove 12 (as shown in fig. 4), so as to enhance the bending strength and tensile strength of the connecting column 14 itself, ensure that the cover plate 2 and the locking body 1 have high connection reliability, and further ensure that the clamping flange 21 thereof has stable locking performance with respect to the clamping jaw 311.
