Description

Technical Field

[0001] The utility model belongs to the technical field of TV signal receivers, in particular to a TV signal receiver. Background Art

[0002] A TV receiver (often called a TV receiver or TV set-top box) is a device that receives and decodes television signals, enabling the television to display the transmitted content. It receives signals from various sources, such as broadcast, satellite, terrestrial, or cable TV, and converts them into images and sounds that the television can display.

[0003] According to the disclosed signal receiver (publication number: CN 105633591 A), it includes a base, a cover, a reflector and a signal receiving device. The base is connected to the cover, and the inner side of the base is connected to the reflector. The reflector is provided with a signal receiver, and the cover is provided with a control button connected to the signal receiver, thereby improving the effectiveness of the signal receiver.

[0004] The base, cover, reflector and other components in the above application cooperate with each other to improve the effectiveness of the signal receiver, but the above application has limited effect in improving the signal reception effectiveness and cannot be more widely accepted. Therefore, we propose a TV signal receiver. Utility Model Content

[0005] The purpose of the utility model is to provide a TV signal receiver, which solves the existing problems.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a TV signal receiver, comprising a base, wherein the top of the base is fixedly connected with a reflector, the inner side of the reflector is fixedly connected with a bracket, one end of the bracket is fixedly connected with a receiver, and the bottom of the base is provided with a lifting device.

[0008] Furthermore, the lifting device includes a force-bearing plate, the top of which is fixedly connected to the bottom of the base, the side of which is slidably connected to a chassis, the inner bottom of the chassis is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the bottom of the chassis is fixedly connected to a limiting rod, the side of the threaded sleeve is fixedly connected to an extension rod, and one end of the extension rod is fixedly connected to a push rod. The device mainly drives the threaded rod to rotate by a motor, thereby driving the threaded sleeve and the extension rod to move up and down, and finally realizes the lifting and lowering of the object through the push rod. The limiting rod ensures that the entire system does not exceed the safety range during movement, avoiding system loss of control or damage. This achieves the lifting and lowering of the TV signal receiver, making it easier to find the signal.

[0009] Furthermore, the side of the threaded sleeve is slidably connected to the side of the limit rod, and one end of the push rod is fixedly connected to the bottom of the load-bearing plate. The sliding connection between the threaded sleeve and the limit rod, and the fixed connection between the push rod and the load-bearing plate, ensure stable and precise movement of the lifting device and effectively transmit the lifting force to the object, ensuring the safety and efficiency of the device during use.

[0010] Furthermore, the diameter of the load-bearing plate is larger than that of the base, and a gap is formed between one end of the threaded rod and the bottom of the load-bearing plate. This design, in which the load-bearing plate has a larger diameter than the base and the gap between the threaded rod and the bottom of the load-bearing plate, complements each other, ensuring the stability, smooth movement, and durability of the device.

[0011] Furthermore, a gap is formed between one end of the limit rod and the bottom of the load-bearing plate, and a gap is formed between the side of the push rod and the side of the threaded rod. The gaps between the limit rod and the load-bearing plate, and between the push rod and the threaded rod, are designed to alleviate stress concentration, reduce friction, compensate for errors, avoid sticking, and provide system flexibility, ensuring long-term stable operation of the mechanical equipment and reducing problems caused by factors such as temperature changes and wear.

[0012] Furthermore, the threaded rod is provided with a rotating device on its circumference. The rotating device includes a rotating sleeve fixedly connected to the threaded rod. A telescopic rod is fixedly connected to the top of the rotating sleeve. The top of the force-bearing plate is provided with an opening, and a rotating disk is rotatably connected to the side of the opening. This design is intended to control the receiving direction of the TV signal receiver through the rotating device, thereby enhancing the receiving strength of the TV signal receiver.

[0013] Furthermore, the diameter of the rotating disk is smaller than the diameter of the opening, and there is a gap between the side of the telescopic rod and the side of the limiting rod. The diameter of the rotating disk is smaller than the diameter of the opening, which can ensure that the rotating disk has enough space to rotate freely and avoid getting stuck or hindering its normal rotation.

[0014] Furthermore, one end of the telescopic rod is fixedly connected to the bottom of the rotating disk, and a gap is formed between the side of the telescopic rod and the side of the top rod. The design of the gap between the telescopic rod and the top rod is very important in mechanical systems, mainly to reduce friction, adapt to temperature changes and mechanical deformation, alleviate vibration and shock, tolerate manufacturing errors, and improve system stability and reliability.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model is achieved by the mutual cooperation of components such as a motor, a threaded rod, a threaded sleeve, and a push rod. When the motor is started, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to move vertically under the restriction of the limit rod. The vertical movement of the threaded sleeve drives the extension rod to move vertically. The vertical movement of the extension rod drives the push rod to move vertically. The vertical movement of the push rod drives the force plate to move vertically. The vertical movement of the force plate drives the TV signal receiver to move vertically, thereby achieving the effect of lifting the TV signal receiver and facilitating the TV signal receiver to find signals.

[0017] 2. The utility model realizes the mutual cooperation of components such as a motor, a threaded rod, and a rotating sleeve. When the motor is started, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the rotating sleeve to rotate. The rotation of the rotating sleeve drives the telescopic rod to rotate. The rotation of the telescopic rod drives the rotating disk to rotate. The rotation of the rotating disk drives the base to rotate. The rotation of the base drives the TV signal receiver to rotate to search for signals, thereby enhancing the ability of the TV signal receiver to find signals.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The lifting device 5 includes a load-bearing plate 51, the top of which is fixedly connected to the bottom of the base 1. The side of the load-bearing plate 51 is slidably connected to a chassis 52. The inner bottom of the chassis 52 is fixedly connected to a motor 53. The output shaft of the motor 53 is fixedly connected to a threaded rod 54. The circumferential surface of the threaded rod 54 is threadedly connected to a threaded sleeve 55.

The device mainly drives the threaded rod 54 to rotate by the motor 53, which in turn drives the threaded sleeve 55 and extension rod 57 to move up and down, and finally achieves the lifting and lowering of the object through the push rod 58. The limit rod 56 ensures that the entire system does not exceed the safe range during movement, preventing the system from losing control or being damaged. This achieves the lifting and lowering of the TV signal receiver, making it easier to find the signal.

[0030] The side of the threaded sleeve 55 is slidably connected to the side of the limit rod 56, and one end of the push rod 58 is fixedly connected to the bottom of the load-bearing plate 51.

[0032] There is a gap between one end of the limit rod 56 and the bottom of the load-bearing plate 51, and between the side of the push rod 58 and the side of the threaded rod 54. The gaps between the limit rod 56 and the load-bearing plate 51, and between the push rod 58 and the threaded rod 54, are designed to relieve stress concentration, reduce friction, compensate for errors, avoid sticking, and provide system flexibility, ensuring long-term stable operation of the mechanical equipment and reducing problems caused by factors such as temperature changes and wear.

[0033] The circumference of threaded rod 54 is provided with a rotating device 6, which includes a rotating sleeve 61 fixedly connected to the circumference of threaded rod 54.
