Description

Technical Field

[0001] This utility model relates to the technical field of telephone brackets, specifically to an openable and closable telephone bracket mechanism with a self-locking pre-compression function. Background Technology

[0002] A typical desktop telephone includes a keypad and a display screen. The keypad is used for dialing, and the display screen is used to show incoming and outgoing call information. To make the keypad and display screen easily visible to the user, the telephone needs to be placed in a convenient and accessible location.

[0003] Typically, desktop telephones are placed flat on a table. In this case, users need to adjust their position to use the telephone comfortably, which is quite inconvenient. A common solution is to install a stand at the bottom of the telephone at a slight angle (e.g., 35 degrees or 55 degrees) to the table, securing the telephone to the stand and achieving a comfortable position. Traditional telephone stands often use clips or magnets for fixation, which have the following drawbacks: clips are prone to wear and loosening; magnetic structures are difficult to precisely control the preload and are easily shifted by external forces; and they lack self-locking in the open / closed state, resulting in poor long-term stability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an openable telephone stand mechanism with a self-locking pre-compression function.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a closable telephone bracket mechanism with a self-locking preload function, comprising a telephone body and a bracket body. The back side of the telephone body is provided with a pair of horizontally arranged mounting holes, and a tightening shaft is installed in the mounting holes. A preload spring is provided between the tightening shaft and the inner side of the mounting hole. The front end of the tightening shaft is provided with an insertion part, and the front end of the insertion part is provided with symmetrically arranged closing inclined surfaces. The insertion part is provided with an opening inclined surface between the closing inclined surfaces. The bracket body is provided with a rotating circular hole for the insertion part to be inserted, and the inner side of the rotating circular hole is provided with an inner inclined surface that engages with the closing inclined surface. The telephone body is provided with a positioning mechanism to prevent the tightening shaft from rotating.

[0007] As a preferred embodiment of the present invention, the positioning mechanism includes a positioning block disposed in the mounting hole and perpendicular to the mounting hole, and the clamping shaft is provided with a strip hole for the positioning block to be inserted, the length direction of the strip hole being consistent with the mounting hole.

[0008] As a preferred embodiment of this utility model, the inner side of the telephone body is provided with a mounting port that communicates with the mounting hole and is used to install the top clamping shaft.

[0009] As a preferred embodiment of this utility model, the inclination angles of both the closed inclined plane and the open inclined plane are 5°-15°.

[0010] As a preferred embodiment of this utility model, the parts of the insertion part that contact the support body are provided with a wear-resistant coating.

[0011] As a preferred embodiment of this utility model, the telephone body is provided with a limiting groove, and the bracket body is provided with a limiting block that moves along the limiting groove when the bracket body rotates.

[0012] The beneficial effects of this utility model are:

[0013] This type of openable telephone bracket mechanism with self-locking preload provides a clamping force to the clamping shaft through a preload spring. Then, two symmetrically arranged closed inclined surfaces are set in the insertion part of the clamping shaft. The inner side of the rotating circular hole is provided with an inner inclined surface that meshes with the closed inclined surface. In this way, the cooperation of the meshing inner inclined surface and the closed inclined surface plays a self-locking role on the bracket body. This utility model converts the linear elastic force of the preload spring into a rotational locking force to achieve self-locking of the bracket in the open and closed state. The open and closed state is stably maintained by the cooperation of the spring and the inclined surface, and it resists loosening caused by external vibration. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1-6 As shown, this utility model discloses an openable telephone stand mechanism with a self-locking preload function, comprising a telephone body 1 and a stand body 2. Both the telephone body 1 and the stand body 2 adopt the shape of existing product mechanisms, with some modifications to the telephone body to facilitate assembly. The modifications are as follows: the back side of the telephone body 1 has a pair of horizontally arranged mounting holes 3, and a clamping shaft 4 is installed in each mounting hole 3. A preload spring 5 is provided between the clamping shaft 4 and the inner side of the mounting hole 3; the stiffness coefficient of the preload spring 5 is k=1.2N / mm, and the specific stiffness of the preload spring 5 can be selected according to actual needs.

[0024] The front end of the clamping shaft 4 is provided with an insertion part 6 for easy rotation. The front end of the insertion part 6 has symmetrically arranged closing inclined surfaces 7, and the insertion part 6 has an opening inclined surface 9 between the closing inclined surfaces. The bracket body 2 has a rotating circular hole 10 for the insertion part 6 to be inserted into, and the inner side of the rotating circular hole 10 has an inner inclined surface 11 that engages with the closing inclined surface 7. Thus, the closing inclined surface, the opening inclined surface 9, and the inner inclined surface form a double-inclined self-locking mechanism, which provides self-locking for the bracket body 2. Self-locking in both closed and open states is achieved through spring force decomposition. The bracket body has an over-angle design (e.g., ±3°~5°) in both closed and open states to ensure that the spring force always applies normal pressure.

[0025] The telephone body 1 is equipped with a positioning mechanism to prevent the top-tightening shaft 4 from rotating. A preloaded spring 5 provides a tightening force to the top-tightening shaft 4, and two symmetrically arranged closed inclined surfaces 7 are provided in the insertion part 6 of the top-tightening shaft 4. The inner side of the rotating circular hole 10 is provided with an inner inclined surface 11 that engages with the closed inclined surface 7. In this way, the engagement of the inner inclined surface 11 and the closed inclined surface 7 achieves a self-locking effect on the bracket body 2. This utility model converts the linear elastic force of the preloaded spring 5 into a rotational locking force to achieve self-locking of the bracket in the open and closed state. The spring and the inclined surface work together to maintain the open and closed state stably and resist loosening caused by external vibration.

[0026] The positioning mechanism includes a positioning block 12 disposed within the mounting hole 3 and perpendicular to the mounting hole 3. The clamping shaft 4 is provided with a strip hole 13 for the positioning block 12 to be inserted. The length direction of the strip hole 13 is consistent with the mounting hole 3. The positioning block is inserted into the strip hole and moves linearly along the strip hole, which prevents the clamping shaft from rotating and allows the clamping shaft to move linearly. Thus, under the elastic force of the preload spring, the clamping force on the bracket body is better.

[0027] In terms of product technical effects, this utility model allows users to complete the opening and closing operation with a single finger, and provides clear tactile feedback when switching; the bracket does not wobble when stationary and can withstand lateral thrust of more than 500g.

[0028] The telephone body 1 has an inner mounting port 14 that communicates with the mounting hole 3 and is used to install the tightening shaft 4, which facilitates the installation of the tightening shaft inside the mounting hole; the telephone body 1 has an inner mounting port 14 that communicates with the mounting hole 3 and is used to install the tightening shaft 4.

[0029] The inclination angles of both the closed inclined plane 7 and the open inclined plane 9 are 5°-15°, and the specific inclination angle can be set according to requirements. In one embodiment, the inclination angle of the closed inclined plane 7 is 8°, and the inclination angle of the open inclined plane 9 is 12°, which can adapt to the operating force requirements of different states. Operating force test: closing → opening requires 0.8~1.2N of thrust, and the reverse operating force is 1.0~1.5N; vibration test: at an amplitude of ±2mm and a frequency of 20Hz, the support has no displacement.

[0030] The insertion part 6 is provided with a wear-resistant plating layer at the part that contacts the bracket body 2. The wear-resistant plating layer can be a hard chrome layer with a thickness of 0.05 mm.

[0031] The telephone body 1 is provided with a limiting groove 15, and the bracket body 2 is provided with a limiting block 16 that moves along the limiting groove 15 when the bracket body 2 rotates, thereby limiting the rotation angle of the bracket body 2.

[0032] Working principle: This type of openable telephone bracket mechanism with self-locking pre-compression function provides a clamping force to the clamping shaft 4 through the pre-compression spring 5. Then, two symmetrically arranged closed inclined surfaces 7 are set in the insertion part 6 of the clamping shaft 4. The inner side of the rotating circular hole 10 is provided with an inner inclined surface 11 that meshes with the closed inclined surface 7. In this way, the cooperation of the meshing inner inclined surface 11 and the closed inclined surface 7 plays a self-locking role on the bracket body 2. This utility model converts the linear elastic force of the pre-compression spring 5 into a rotational locking force to realize the self-locking of the bracket in the open and closed state. The open and closed state is stably maintained by the cooperation of the spring and the inclined surface, and it resists loosening caused by external vibration.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
