Description

Technical Field

[0001] This utility model relates to the technical field of electric bed stop holders, specifically a stop holder for an electric bed. Background Technology

[0002] The stop bar seat is used to connect with the single bar. During the process of raising the electric bed, the mattress may slip off. Therefore, a stop bar is usually installed at the foot of the electric bed to prevent the mattress from slipping off.

[0003] The stop lever seat used in electric beds is generally a cylindrical structure, with the stop lever inserted into the seat. Currently, the inner wall of the stop lever seat used in electric beds is generally smooth. Firstly, during insertion, the stop lever rubs against the entire inner wall of the seat, resulting in significant friction. Secondly, when the stop lever seat is inserted into the pre-drilled hole in the bed board, the smooth inner wall makes the stop lever prone to loosening after prolonged use. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a stop lever seat for an electric bed to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stop lever seat for an electric bed, comprising a cylindrical seat, wherein notches are symmetrically opened on both side walls of the lower part of the cylindrical seat, the bottom of the notches are interconnected with the outside of the cylindrical seat, and a plurality of chamfered protrusions are provided on the outer surface of the cylindrical seat in a direction perpendicular to the two notches, and a plurality of elongated bosses are uniformly arranged on the inner wall of the cylindrical seat along the axial direction, and a plurality of grooves are opened on the inner surface of the elongated bosses, wherein the inner surface of the elongated bosses forms an anti-slip serrated structure through the grooves.

[0006] Preferably, the present invention provides a stop bar seat for an electric bed, wherein a limiting plate is provided on the periphery of the top end of the cylindrical seat.

[0007] Preferably, the present invention provides a stop lever seat for an electric bed, wherein the cross-section of the chamfered protrusion is triangular, the upper surface of the chamfered protrusion is a horizontal plane, and the lower surface of the chamfered protrusion is an inclined plane.

[0008] Preferably, the present invention provides a stop bar seat for an electric bed, wherein two of the elongated protrusions are each located directly above the notch.

[0009] Preferably, the present invention provides a stop bar seat for an electric bed, wherein the width of the notch gradually increases from top to bottom.

[0010] Preferably, the stop bar seat for an electric bed provided by this utility model is wherein the cylindrical seat, the chamfered protrusion, the elongated boss and the limiting plate are integrally formed.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The inner wall of the cylindrical seat is uniformly provided with several elongated protrusions along the axial direction. When inserting the stop bar, the friction is reduced to facilitate the insertion of the stop bar. At the same time, the inner wall of the elongated protrusions is provided with grooves to form an anti-slip serrated structure. When the cylindrical seat is inserted into the reserved hole of the bed board, the friction between it and the stop bar is increased, preventing the stop bar from easily slipping out. Furthermore, when the cylindrical seat is pressed into the reserved hole of the bed board, the elongated protrusions can cause plastic deformation of each serration through the grooves, preventing the stop bar from being pressed too tightly and making it difficult to insert into the reserved hole of the bed board.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: a stop lever seat for an electric bed, including a cylindrical seat 1. The lower two side walls of the cylindrical seat 1 have symmetrical notches 2, the bottom of which communicate with the outside of the cylindrical seat 1. The width of the notches 2 gradually increases from top to bottom to ensure that the cylindrical seat 1 can smoothly approach the notches 2 when inserted. Several chamfered protrusions 3 are provided on the outer surface of the cylindrical seat 1 in a direction perpendicular to the two notches 2. The cross-section of the chamfered protrusions 3 is triangular, the upper surface of which is horizontal, and the lower surface is inclined. This structure prevents the cylindrical seat 1 from slipping out of the pre-drilled hole in the bed board when inserted. The inner wall of the cylindrical seat 1 is uniformly provided with several elongated protrusions 4 along the axial direction. Two of the elongated protrusions 4 are located directly above the notch 2 to ensure the structural strength of the cylindrical seat 1 at the notch 2 and reduce the probability of damage. The inner surface of each elongated protrusion 4 is provided with several grooves 5, and the inner surface of the elongated protrusion 4 forms an anti-slip serrated structure through the grooves 5. A limiting plate 6 is provided on the outer periphery of the top of the cylindrical seat 1. The limiting plate 6 cooperates with the upper surface of the bed board when the stop bar seat is installed to limit the position of the cylindrical seat 1. The cylindrical seat 1, the chamfered protrusion 3, the elongated protrusions 4 and the limiting plate 6 are integrally formed structures, which facilitates processing and ensures the overall structural strength.

[0021] Usage and Operating Principle: The cylindrical seat 1 is injection molded. Then, the elongated boss 4 inside the cylindrical seat 1 is slotted using in-mold hot cutting or machining, creating an anti-slip serrated structure on the inner wall of the elongated boss 4, thus obtaining the stop bar seat. In use, first insert both ends of the stop bar into the cylindrical seat 1. Then, use a tool to tap the two cylindrical seats 1 connected to the stop bar into the pre-drilled holes at the tail end of the electric bed board, causing the lower surface of the limiting plate 6 to press against the upper surface of the bed board. At this time, the portions of the cylindrical seats 1 located on both sides of the notch 2 approach each other and press against the pre-drilled holes in the bed board. The compression and contraction of the elongated boss 4 clamps the stop bar. The chamfered protrusions 3 prevent the cylindrical seat 1 from easily sliding out of the pre-drilled holes in the bed board, completing the installation. Figure 4 As shown. This utility model has a reasonable structure. The inner wall of the cylindrical seat 1 is uniformly provided with several elongated protrusions 4 along the axial direction. When inserting the stop bar, it reduces friction and facilitates the insertion of the stop bar. At the same time, the inner wall of the elongated protrusions 4 has grooves 5 to form an anti-slip serrated structure. When the cylindrical seat 1 is inserted into the reserved hole of the bed board, it increases the friction between it and the stop bar, preventing the stop bar from easily slipping out. Furthermore, when the cylindrical seat 1 is pressed into the reserved hole of the bed board, the elongated protrusions 4, through the grooves 5, allow each serration to undergo plastic deformation, preventing the stop bar from being pressed too tightly and making it difficult to insert into the reserved hole of the bed board. Of course, this structure is also applicable to inserting the cylindrical seat 1 into the reserved hole of the bed board first, and then inserting the insert bar.
