Description

Technical Field

[0001] This utility model relates to the field of digital television receiver card technology; more specifically, it relates to a digital television receiver card guiding structure. Background Technology

[0002] Digital television is a form of television broadcasting that transmits signals digitally. Compared to traditional analog television, digital television offers higher image quality, better sound quality, more channel options, and interactive services. The digital television receiver card is one of the more important components of digital television.

[0003] A digital television receiver card is a hardware device used to receive digital television signals, typically plugged into a computer's PCI or PCI-E slot. It can receive digital television signals from cable television, satellite television, or terrestrial broadcasts.

[0004] Currently, in existing digital TV receiver cards, the plastic clips are typically positioned inside the digital TV motherboard during use. However, this positioning method can easily lead to a decrease in the elasticity of the plastic clips or breakage after repeated insertion and removal, thus affecting the performance of the receiver card and reducing the practicality of the device to some extent. Furthermore, during prolonged use, accidental contact or impact may cause the receiver card to loosen, further affecting the digital TV experience and reducing the practicality of the device. Therefore, there is an urgent need for a digital TV receiver card guiding structure to solve these problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a digital television receiver card guide structure to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a digital television receiver card guide structure, comprising:

[0007] The digital TV card body has a guide groove inside, into which a digital TV receiver card body is inserted. One end of the digital TV receiver card body has a connecting groove, and both sides of the other end have card slots. One end of the outer surface of the digital TV card body is fixedly connected to a mounting plate, which has a positioning structure inside and a protective structure on one side of its outer surface. The positioning structure includes an insertion slot and a card block, with the insertion slot located in the middle of the mounting plate. The protective structure includes an elastic groove located at the top of one side of the outer surface of the mounting plate.

[0008] Preferably, the positioning structure further includes a groove, and there are two sets of grooves. The two sets of grooves are respectively opened on both sides inside the insertion slot. A spring is fixedly connected to one end of the groove, and a limit block is fixedly connected to one end of the spring. A locking block is fixedly connected to the end of the outer surface of the limit block away from the spring. This design can perform positioning operations on the main body of the digital TV receiver card.

[0009] Preferably, the internal dimensions of the groove are adapted to the external dimensions of the limiting block, which makes the movement of the locking block more stable.

[0010] Preferably, both sides of the outer surface of the card block are designed to be inclined, and the external dimensions of the card block are adapted to the internal dimensions of the card slot. This design allows the card block to be accurately inserted into the inside of the card slot.

[0011] Preferably, the protective structure further includes a positioning groove, which is located at the top of the elastic groove. A protective plate is hinged to one side of the outer surface of the mounting plate, and a spring plate is fixedly connected to one end of the protective plate. A positioning block is fixedly connected to the outer surface of the spring plate, and a pull plate is fixedly connected to one end of the spring plate. This design allows for positioning of the protective plate.

[0012] Preferably, one side of the outer surface of the positioning block is inclined, and the external dimensions of the positioning block are adapted to the internal dimensions of the positioning groove. This design allows the spring plate to be inserted into the spring groove more smoothly.

[0013] The technical effects and advantages of this utility model are as follows: By inserting the main body of the digital TV receiver card into the guide groove, the outer surface of the main body of the digital TV receiver card contacts the inclined surface of the card block, which can press the card block to move back into the groove until the card block moves back to the appropriate position. Then, the main body of the digital TV receiver card can be inserted into the bottom position of the guide groove. Under the elasticity of the spring, the card block can be ejected outward and locked into the card slot. At this time, the installation position of the main body of the digital TV receiver card can be positioned. This design can position the main body of the digital TV receiver card inside the guide groove, which is more stable than the traditional plastic card positioning method and can be repeatedly inserted and removed, thus improving the practicality of the device to a certain extent.

[0014] By hinged rotating the protective plate, the spring plate is inserted into the elastic groove, allowing the outer surface of the mounting plate to conform to the inclined surface of the positioning block. When the thrust exceeds the spring plate's own elasticity, the outer surface of the mounting plate presses the positioning block back, allowing both the spring plate and the positioning block to be inserted into the elastic groove. When the protective plate completely covers the outer surface of one end of the digital TV receiver card body, the spring plate's own elasticity can eject the positioning block outward and lock it into the positioning groove. This allows the protective plate to be positioned after rotation. This design protects the digital TV receiver card body from accidental contact or collision, preventing it from becoming loose and maintaining stable operation. It improves the practicality of the equipment to a certain extent, and its overall structure is simple, reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The digital television receiver card involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1, as Figures 1-3 As shown, this embodiment proposes a digital television receiver card guiding structure, including:

[0023] The digital TV card body 1 has a guide groove 2 inside, and a digital TV receiver card body 3 is inserted into the guide groove 2. A connecting groove 4 is opened at one end of the digital TV receiver card body 3, and card slots 5 are opened on both sides of the other end of the digital TV receiver card body 3. An installation plate 6 is fixedly connected to one end of the outer surface of the digital TV card body 1. A positioning structure 7 is set inside the installation plate 6, and a protective structure 8 is set on one side of the outer surface of the installation plate 6. This design allows the digital TV receiver card body 3 to be accurately inserted into the guide groove 2 and move along the bottom surface of the guide groove 2 to achieve a guiding effect. When the digital TV receiver card body 3 is inserted into the bottom position of the guide groove 2, the connecting groove 4 can contact the interface of the digital TV card body 1 to achieve a connection effect.

[0024] The positioning structure 7 includes an insertion slot 71 and a locking block 75. The insertion slot 71 is located in the middle of the mounting plate 6. The positioning structure 7 also includes a groove 72, and there are two sets of grooves 72. The two sets of grooves 72 are respectively located on both sides inside the insertion slot 71. A spring 73 is fixedly connected to one end of the groove 72, and a limit block 74 is fixedly connected to one end of the spring 73. A locking block 75 is fixedly connected to the end of the outer surface of the limit block 74 away from the spring 73. Under the elastic action of the spring 73, the limit block 74 can be ejected outward and locked into the inside of the slot 5. This design can position the digital TV receiver card body 3 after it has moved. At this time, the digital TV receiver card body 3 will be inserted into the bottom position inside the guide groove 2, completing the connection operation between it and the digital TV card body 1.

[0025] The internal dimensions of the groove 72 are adapted to the external dimensions of the limiting block 74. This design, under the action of the limiting block 74, can limit the locking block 75 and prevent the locking block 75 from dislodging from the inside of the groove 72.

[0026] Both sides of the outer surface of the card block 75 are designed to be inclined, and the external dimensions of the card block 75 are adapted to the internal dimensions of the card slot 5. This design allows the digital TV receiver card body 3 to move along the inclined surface of the card block 75 when inserted into the insertion slot 71, and to move along the other inclined surface of the card block 75 when the digital TV receiver card body 3 is inserted or removed, making it easier and more convenient to insert or remove the digital TV receiver card body 3.

[0027] Example 2, as Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] The protective structure 8 includes an elastic groove 81, which is located at the top of one side of the outer surface of the mounting plate 6. The protective structure 8 also includes a positioning groove 82, which is located at the top of the elastic groove 81. A protective plate 83 is hinged to one side of the outer surface of the mounting plate 6. A spring plate 84 is fixedly connected to one end of the protective plate 83. A positioning block 85 is fixedly connected to the outer surface of the spring plate 84. A pull plate 86 is fixedly connected to one end of the spring plate 84. With this design, the positioning block 85 can be ejected outward under the elastic action of the spring plate 84. When the positioning block 85 is inserted into the positioning groove 82, the position of the protective plate 83 after rotation can be positioned.

[0029] One side of the outer surface of the positioning block 85 is designed to be inclined, and the external dimensions of the positioning block 85 are adapted to the internal dimensions of the positioning groove 82. When the positioning block 85 is inserted into the positioning groove 82 and pulled outward, the vertical surface of the positioning block 85 can be made to abut against the vertical surface of the positioning groove 82, making it difficult for the positioning block 85 to fall out of the positioning groove 82.

[0030] In this application, the spring 73, the spring plate 84, and the positioning block 85 are all products that can be purchased directly from the market. Their principles, connection methods, and control methods are all existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0031] Working principle: When using the device, first insert the output end of the digital TV receiver card body 3 into the insertion slot 71, extending into the guide slot 2. At this time, after the outer surface of the digital TV receiver card body 3 contacts the inclined surface of the card block 75, when the pushing force is greater than the elastic force of the spring 73, the card block 75 can be pressed back into the groove 72 until the card block 75 moves back to the appropriate position. Then, the digital TV receiver card body 3 can be inserted into the bottom position inside the guide slot 2, and the connecting slot 4 can contact the interface of the digital TV card body 1 to achieve the connection effect. At this time, the card block 75 and the card slot 5 are in corresponding positions, and under the elastic action of the spring 73, the card block 75 can be popped out and locked into the inside of the card slot 5. This design allows for positioning of the digital TV receiver card body 3, ensuring a stable connection between the digital TV receiver card body 3 and the digital TV receiver card body 1. When the digital TV receiver card body 3 needs to be replaced or repaired, simply pull the digital TV receiver card body 3 outward. When the pulling force exceeds the elastic force of the spring 73, the inner wall surface of the card slot 5 will move against the inclined surface of the card block 75, and the card block 75 will be pressed back into the groove 72 until the card block 75 is disengaged from the inside of the card slot 5. This cancels the positioning effect on the digital TV receiver card body 3, allowing the digital TV receiver card body 3 to be removed from the inside of the guide groove 2 for easy maintenance or replacement by staff.

[0032] When the device is in use, the hinged rotating protective plate 83 allows the spring plate 84 to be inserted into the elastic groove 81, causing the outer surface of the mounting plate 6 to conform to the inclined surface of the positioning block 85. When the thrust is greater than the spring force of the spring plate 84, the outer surface of the mounting plate 6 can press the positioning block 85 back, allowing both the spring plate 84 and the positioning block 85 to be inserted into the elastic groove 81. When the protective plate 83 completely covers the outer surface of one end of the digital TV receiver card body 3, the positioning block 85 can be ejected outwards and locked into the positioning groove 82 under the elasticity of the spring plate 84. This allows for positioning of the protective plate 83 after rotation. This design, under the action of the protective plate 83, protects one end of the digital TV receiver card body 3, preventing accidental damage due to accidental contact. In the event of a misalignment, the connection between the digital TV receiver card body 3 and the digital TV card body 1 is maintained. After the equipment is used, the pull plate 86 can be pressed to retract one end of the spring plate 84, thereby retracting the positioning block 85 until the positioning block 85 is disengaged from the positioning groove 82. This cancels the positioning effect between the protection plate 83 and the designated mounting plate 6. At this time, the digital TV receiver card body 3 can be removed from the guide groove 2. After removing the digital TV receiver card body 3, the above operation can be repeated to reposition the protection plate 83 and seal the opening of the insertion groove 71. This can block dust and prevent a large amount of dust from entering the interior of the digital TV card body 1 during equipment maintenance. The above is the complete working principle of this utility model.

[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0034] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0035] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
