Pressing fastener and LED (light-emitting diode) display screen connected by utilizing same

Abstract

The invention discloses a pressing fastener which comprises a fixing seat, a longitudinal sliding block, an elastic element, a transverse sliding block and a sliding pin nail, wherein the fixing seat is provided with a plug-in mounting hole along the length direction; the longitudinal sliding block can slide along the height direction of the fixing seat; the elastic element is installed between the longitudinal sliding block and the upper end part of the fixing seat; the transverse sliding block can slide along the length direction of the fixing seat, the inner side end of the transverse sliding block is an inclined surface, and the inclined surface is positioned below the bottom end part of the longitudinal sliding block in a positive corresponding mode; the sliding pin nail passes through the plug-in mounting hole and can slide along the length direction of the fixing seat, and the sliding pin nail is provided with a first limiting groove in which the longitudinal sliding block can be embedded and a second limiting groove in which the transverse sliding block can be embedded; and the length of the part, embedded in the second limiting groove, of the horizontal sliding block is less than that of the second limiting groove. By utilizing the pressing fastener, the rapid mounting and dismounting of components can be realized, the mounting and dismounting processes are simplified greatly, the mounting efficiency is improved, the pressing fastener is convenient to maintain daily, especially the pressing fastener is installed on an LED (light-emitting diode) display screen, the fastening property is higher, and the pressing fastener is convenient to install, is time-saving and labor-saving, and is easy to dismount.

Description

[0001] technical field [0002] The invention relates to a fastening connection device, in particular to a push-type fastener, and at the same time, the invention also relates to an LED display screen connected by the push fastener. [0003] Background technique [0004] In the process of product assembly, when two or more parts need to be fastened together, it is usually realized by standard parts such as screws, bolts or rivets. These standard parts usually need to be connected to the parts to be fastened manually or by machine. For example, screw connection requires repeated screwing operations, which will consume a lot of manpower and material resources. This defect is particularly prominent in the connection of LED displays. The existing LED displays are made of standard size The display modules are spliced ​​together, specifically as follows figure 1 As shown, the display module is fixed to the frame by screws, and the edge of the frame and the display module is conn...

[0004] In the process of product assembly, when two or more parts need to be fastened together, it is usually realized by standard parts such as screws, bolts or rivets. These standard parts usually need to be connected to the parts to be fastened manually or by machine. For example, screw connection requires repeated screwing operations, which will consume a lot of manpower and material resources. This defect is particularly prominent in the connection of LED displays. The existing LED displays are made of standard size The display modules are spliced ​​together, specifically as follows figure 1 As shown, the display module is fixed to the frame by screws, and the edge of the frame and the display module is connected by screws, which makes the installation of the LED display more complicated and difficult to disassemble; there are also some LED displays such as figure 2 As shown, the LED display module is adsorbed to the frame by magnetic columns, but this connection structure is not strong enough, and it is easy to fall off and damage the LED display module
