Technical Field
[0001] This utility model belongs to the field of display screen frame technology, specifically relating to a display screen frame that improves dust interception. Background Technology
[0002] In short, the bezel of an LCD screen is a frame that is fixed to the outside of the screen. This frame is usually made of plastic, which has a certain degree of elasticity and toughness. The main functions of the bezel are: to protect the screen, to increase structural strength, and to enhance aesthetics.
[0003] For example, CN221651134U discloses a display screen frame that is easy to install, including a first frame and a second frame. Both ends of the first frame are fixedly connected to a mounting plate, and both ends of the second frame are provided with mounting slots. One end of the mounting plate is disposed in the corresponding mounting slot and is fixedly connected to the second frame by a locking rod. The inner sides of the first frame and the second frame are provided with mounting grooves. Sealing gaskets are provided on the top and bottom inner walls of the mounting grooves. The side walls of the mounting grooves are provided with heat dissipation grooves. The heat dissipation grooves are provided with a plurality of heat dissipation fins. The sides of the first frame and the second frame that are far apart from each other are provided with a plurality of heat dissipation holes, and the heat dissipation holes are connected to the heat dissipation grooves.
[0004] In the above solution, the heat dissipation holes are directly connected to the heat dissipation slot, making it easy for external dust to enter the heat dissipation slot. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a display screen frame that improves dust interception. This application improves dust interception by setting a dust cover, a conical cover, and a conical ring inside the heat dissipation holes, thereby reducing the amount of dust entering through the heat dissipation holes.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A display screen bezel with improved dust interception effect, comprising:
[0008] A frame, which is fixedly installed on the outside of the display screen;
[0009] The frame includes a first frame and a second frame detachably connected to the first frame. A rectangular protrusion and a first rectangular stop bar protrude outward on the side of the first frame near the second frame. The first rectangular stop bar is located inside the rectangular protrusion. A second rectangular stop bar protrudes outward on the side of the second frame near the first frame. A slot is formed between the first frame, the second frame, the first rectangular stop bar, and the second rectangular stop bar. The side of the display screen is engaged in the slot.
[0010] The rectangular protrusion has several heat dissipation holes. A sleeve is fixedly connected inside the heat dissipation holes. A dust cover is fixedly connected to the outer end of the sleeve. A connecting rod is fixedly connected to the middle of the dust cover. At least one conical cover is fixedly connected to the connecting rod. At least one conical ring is fixedly connected to the inner wall of the sleeve. The conical covers and conical rings are staggered. The diameter of the conical cover gradually increases towards the dust cover, and the diameter of the conical ring gradually decreases towards the dust cover.
[0011] The principles and technical effects of the above technical solution are as follows:
[0012] The display screen frame dissipates heat through ventilation holes. Hot air escapes through the gaps between the conical cover and the conical ring. The dust cover acts as the first line of defense against dust. The first set of conical covers and rings together act as the second line of defense, and the second set of conical covers and rings together act as the third line of defense. The more conical covers and rings there are, the better the dust interception effect. Of course, the heat dissipation effect must also be considered, and an appropriate number must be set. Specifically, when dust enters the ventilation holes, the dust cover will intercept some of the dust. The remaining dust enters the sleeve through the dust cover. Due to the special design of the conical cover and ring, some of the dust is intercepted by the first set of conical covers and rings. Some of the intercepted dust will accumulate in the gap between the conical cover and the connecting rod, and the rest will accumulate in the gap between the conical ring and the inner wall of the sleeve. By setting multiple sets of conical covers and rings, the dust interception effect is improved.
[0013] In a preferred embodiment, the present invention can be further configured such that: two first rectangular sealing strips are provided in the card slot, and the two first rectangular sealing strips are located on both sides of the display screen.
[0014] In a preferred embodiment, the present invention can be further configured such that a second rectangular sealing strip is provided between the second frame and the rectangular protrusion.
[0015] In a preferred embodiment, the present invention can be further configured such that: the rectangular protrusion has a plurality of threaded holes, the second rectangular sealing strip has a first through hole corresponding to each of the threaded holes, and the second frame has a second through hole corresponding to each of the threaded holes.
[0016] In a preferred embodiment, the present invention can be further configured such that: a gap is left between the first rectangular baffle and the second rectangular baffle, a gap is left between the rectangular convex strip and the first rectangular baffle, the gap between the first rectangular baffle and the second rectangular baffle communicates with the gap between the rectangular convex strip and the first rectangular baffle, and the heat dissipation hole communicates with the gap between the rectangular convex strip and the first rectangular baffle.
[0017] In a preferred embodiment, the present invention can be further configured such that the maximum outer diameter of the conical cover is greater than the minimum inner diameter of the conical ring, and a gap is left between the conical cover and the conical ring.
[0018] In a preferred embodiment, the present invention can be further configured such that: a reinforcing rod is fixedly connected to one end of the connecting rod away from the dust cover, and both ends of the reinforcing rod are fixedly connected to the inner wall of the sleeve.
[0019] In a preferred embodiment, the present invention can be further configured such that the four corners of the frame are covered with fixedly connected protective sleeves.
[0020] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0021] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.
[0022] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.
[0023] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.
[0024] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.
[0025] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.
[0026] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.
[0027] The beneficial effects of this utility model are:
[0028] This application improves the dust interception effect and reduces the amount of dust entering through the heat dissipation holes by setting a dust cover, a conical cover, and a conical ring inside the heat dissipation holes. Attached Figure Description

Through the cooperation of structures such as a dust cover 115, a conical cover 117, and a conical ring 118, the display screen frame dissipates heat through the provided heat dissipation holes 113. Hot air escapes through the gap between the conical cover 117 and the conical ring 118. The dust cover 115 serves as the first layer of dust interception, the first set of conical covers 117 and conical rings 118 together serve as the second layer of dust interception, and the second set of conical covers 117 and conical rings 118 together serve as the third layer of dust interception. The more conical covers 117 and conical rings 118 provided, the better the dust interception effect; of course, heat dissipation must also be considered. By setting an appropriate number, specifically, when dust enters the heat dissipation hole, the dust cover 115 will intercept some of the dust. The remaining dust enters the sleeve 114 through the dust cover 115. Due to the special design of the conical cover 117 and the conical ring 118, some of the dust is intercepted by the first set of conical covers 117 and conical ring 118. Part of the intercepted dust will accumulate in the gap between the conical cover 117 and the connecting rod 116, and another part will accumulate in the gap between the conical ring 118 and the inner wall of the sleeve 114. By setting multiple sets of conical covers 117 and conical rings 118, the dust interception effect is improved.

The conical cover 117 and the conical ring 118 are staggered. The diameter of the conical cover 117 gradually increases towards the dust cover 115, and the diameter of the conical ring 118 gradually decreases towards the dust cover 115.
[0044] In this application, the display screen frame dissipates heat through the provided heat dissipation holes 113. Hot air escapes through the gap between the conical cover 117 and the conical ring 118. The dust cover 115 serves as the first layer of dust interception. The first set of conical covers 117 and conical rings 118 together serve as the second layer of dust interception. The second set of conical covers 117 and conical rings 118 together serve as the third layer of dust interception. The more conical covers 117 and conical rings 118 provided, the better the interception effect. Of course, heat dissipation must also be considered, and an appropriate number should be set. Specifically, when dust... When dust enters the heat dissipation hole, the dust cover 115 will intercept some of the dust. The remaining dust enters the sleeve 114 through the dust cover 115. Due to the special design of the conical cover 117 and the conical ring 118, some of the dust is intercepted by the first set of conical covers 117 and conical ring 118. Some of the intercepted dust will accumulate in the gap between the conical cover 117 and the connecting rod 116, and the other part will accumulate in the gap between the conical ring 118 and the inner wall of the sleeve 114.
