Description

A kind of firmly clamping backlight board jacket

technical field

The utility model relates to a firmly clamped backlight board jacket, which belongs to the field of electronic product accessories.

Background technique

The existing LCD screen and the backlight panel are mainly connected together through the backlight panel jacket. The existing backlight panel jacket pushes the pressure block through the bolt. However, the manual rotation of the bolt is greatly affected by human factors, and the tightness depends on experience and feeling. , Therefore, there are differences in the degree of firmness of the fixation, which affects product quality. In addition, there may be air between the soft lining on the bottom surface of the pressing block of the existing backlight jacket and the object to be pressed, and the fixing is not very firm.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art and provide a backlight jacket with firm clamping and precise pressing stroke of the pressing block.

The technical solution adopted by the utility model to solve the technical problem is: a backlight jacket with firm clamping, including a sleeve body, a pressure block and a stroke cylinder, the pressure block is located in the sleeve body, and the sleeve body shell is in the form of steps shape, the lower part is wide, and the upper part is narrow. There is a through hole on the top of the sleeve body. The lower end of the stroke cylinder passes through the through hole to connect the upper surface of the pressing block. The inner wall of the sleeve and the bottom of the pressing block are provided with a soft inner lining. The block is provided with an air extraction device, and the air extraction port of the air extraction device communicates with the lower bottom surface of the soft lining on the briquetting block.

The through hole is located at the center of the top of the casing.

Beneficial effects: (1) The stroke cylinder is used to control the pressing down stroke of the briquetting block, the stroke is precise, human errors are avoided, and the product quality is improved.

(2) An air extraction device is added to make the space between the briquetting block and the object to be pressed into a vacuum state, and the fixation is more firm.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the structural representation of the preferred embodiment of the present utility model;

Fig. 2 is an internal schematic diagram of the utility model.

Detailed ways

As shown in Figures 1 and 2, a backlight jacket with firm clamping includes a sleeve body 1, a pressure block 2 and a stroke cylinder 3, the pressure block 2 is located in the sleeve body 1, and the outer shell of the sleeve body 1 is Step-shaped, wide at the bottom and narrow at the top, a through hole 11 is provided in the center of the top of the sleeve body 1, the lower end of the stroke cylinder 3 passes through the through hole 11 and connects the upper surface of the pressing block 2, the inner wall of the sleeve body 1 and the bottom of the pressing block 2 A soft inner lining 4 is provided, and an air extraction device 5 is arranged on the briquetting block 2, and the air extraction port of the air extraction device 5 communicates with the lower surface of the soft inner lining 4 on the briquetting block.
