Description

Technical Field

[0001] This utility model relates to the field of signal receiving device technology, and in particular to a signal receiving device for broadcasting and television engineering. Background Technology

[0002] In the field of broadcasting and television engineering, signal receiving equipment is a key device for ensuring stable signal reception. As an important component of signal receiving equipment, the performance and stability of the signal antenna directly affect the reception quality of broadcast and television signals.

[0003] Currently, common signal antennas on the market (such as those attached) Figure 5 The digital antenna shown here mostly uses a simple base design. These antennas lack an effective fixing mechanism, which has many drawbacks in practical use. When placed on a relatively smooth surface, the lack of fixing measures makes the antenna prone to slippage due to external forces, thus affecting the stability and strength of signal reception. Furthermore, when subjected to even a slight impact, the antenna is very likely to tip over, potentially damaging the antenna itself, increasing equipment maintenance costs, and interrupting normal reception of broadcast television signals, causing inconvenience to users.

[0004] Therefore, developing a signal receiving device for broadcasting and television engineering with a reliable fixing mechanism and stable placement has significant application value. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned signal receiving device for broadcasting and television engineering, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a broadcast television engineering signal receiving device, including a housing;

[0008] Antenna, comprising:

[0009] The mounting base is fixed to the end of the antenna and hinged to the housing. One side of the base has a continuous guide surface composed of a bevel and a hemispherical groove.

[0010] The clamp is located inside the housing and can slide along its vertical direction;

[0011] A hemispherical protrusion is provided on the top surface of the clamp;

[0012] A spring is elastically connected between the spring and the housing, and under its elastic force, the hemispherical protrusion is always in contact with the guide surface;

[0013] A pressure frame is located in the sliding direction of the clamp;

[0014] When the mounting base rotates around the hinge axis, the clamp contacts the inclined surface and the hemispherical groove in sequence, and is squeezed down by the rotation of the inclined surface to form a clamping structure with the pressure frame. When the clamp contacts the hemispherical groove, a snap-fit ​​structure is formed to lock the relative position of the antenna and the clamp.

[0015] In a preferred embodiment of the broadcast and television engineering signal receiving device of this utility model, the bottom of the clamp extends from inside the housing to outside the housing during the rotation of the mounting base.

[0016] In a preferred embodiment of the broadcast and television engineering signal receiving device of this utility model, the hemispherical groove and the hemispherical protrusion are of the same size, and their surfaces fit together after they come into contact.

[0017] In a preferred embodiment of the broadcast and television engineering signal receiving device of this utility model, the bottom of the clamp is provided with a friction pad made of rubber.

[0018] In a preferred embodiment of the broadcast television engineering signal receiving device described in this utility model, the pressure frame includes:

[0019] Side frame, fixed to the lower surface of the housing;

[0020] The screw is vertically rotated and passes through the side frame;

[0021] The pressure pad is threaded onto the screw and is located in the sliding direction of the clamp.

[0022] In a preferred embodiment of the broadcast and television engineering signal receiving device of this utility model, the bottom surface of the friction pad and the top surface of the pressure pad are both provided with anti-slip stripes.

[0023] The beneficial effects of this invention are as follows: the clamp can slide down synchronously when the antenna rotates, thus forming a clamping structure with the bottom pressure frame, making it easy to fix the antenna in a suitable position. Simultaneously, when the antenna rotates to a vertical position, the locking structure formed by the hemispherical groove and hemispherical protrusion can lock the relative position of the antenna and the clamp, effectively preventing slippage or tilting, thereby improving the stability of the received signal.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0034] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0035] Reference Figures 1-4 As an embodiment of the present invention, a broadcast television engineering signal receiving device is provided, which includes a housing 1, which serves as the base shell of the entire device and provides an installation foundation and housing space for the internal components.

[0036] Antenna 2 includes a mounting base 21, which is fixed to the end of antenna 2 and hinged to housing 1, allowing antenna 2 to rotate about the hinge axis. One side of antenna 2 is provided with a continuous guide surface composed of inclined surface 210 and hemispherical groove 211.

[0037] The clamp 3 is located inside the housing 1 and can slide along its vertical direction. The bottom of the clamp 3 is provided with a friction pad 33, which is made of rubber and has anti-slip stripes on the bottom surface. The friction pad 33 increases the friction with the surface of the object being clamped.

[0038] A hemispherical protrusion 31 is provided on the top surface of the clamp 3; the hemispherical groove 211 and the hemispherical protrusion 31 have the same size, and their surfaces fit together after they come into contact.

[0039] Spring 32 is elastically connected between spring 32 and housing 1. Under the action of elastic force, the hemispherical protrusion 31 is always in contact with the guide surface of mounting base 21, ensuring that the clamp 3 can move along the predetermined trajectory with the antenna 2 to realize the clamping and locking functions.

[0040] Pressure frame 4 is located in the sliding direction of clamp 3; pressure frame 4 includes:

[0041] The side frame 41 is fixed to the lower surface of the housing 1 and provides mounting support for the screw 42 and the pressure pad 43.

[0042] The screw 42 is vertically rotatably mounted on the side frame 41. The height of the pressure pad 43 can be adjusted by rotating the screw 42.

[0043] The pressure pad 43 has anti-slip stripes on its top surface and is threaded onto the screw 42. It is located in the sliding direction of the clamp 3. During the sliding process of the clamp 3, it cooperates with the bottom of the clamp 3 to form a clamping structure. By adjusting the screw 42, the distance between the pressure pad 43 and the clamp 3 can be changed to adapt to different size requirements and enhance the stability of the antenna 2.

[0044] When the mounting base 21 rotates around the hinge axis, the antenna 2 changes from a horizontal state to a vertical state, which facilitates the reception of broadcast television signals. During this process, the clamp 3 can sequentially contact the inclined surface 210 and the hemispherical groove 211, and be squeezed by the rotation of the inclined surface 210 to slide down and form a clamping structure with the pressure frame 4, which can install it in a suitable position to fix the position of the antenna 2. At the same time, when the clamp 3 contacts the hemispherical groove 211, it can form a snap-fit ​​structure to lock the relative position of the antenna 2 and the clamp 3, effectively preventing the antenna 2 from shifting during use and further improving the stability of signal reception.

[0045] In addition, it should be noted that during the rotation of the mounting base 21, the bottom of the clamp 3 extends from inside the housing 1 to outside the housing 1, thereby forming an effective clamping structure with the pressure pad 43 to achieve the effect of automatic fixation, making the operation efficient and convenient.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
