Description

Technical Field

[0001] This utility model relates to a connector, and more specifically to a groove-type connector and a bed made therefrom. Background Technology

[0002] Traditional connectors used to fix long bed slats (or bed crossbars) often have the following typical drawbacks in terms of structure, materials, and function: 1. Most traditional connectors are a combination of metal sheets and screws; installation requires precise measurement of position, drilling, and screwing, resulting in high labor costs and a high risk of error; once the position is incorrect, readjustment is difficult; 2. Some metal parts are prone to loosening due to thermal expansion and contraction and bed board deformation after prolonged contact with wood; especially screw connectors, which may cause the screw holes to loosen after long-term use, producing creaking sounds or structural instability.

[0003] It is necessary to develop a screwless connector to facilitate installation and maintenance. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a network-connected seat.

[0005] The objective of this utility model is achieved through the following technical solutions:

[0006] This utility model relates to a slotted connector for connecting a lower fixed object and a strip-shaped object. It includes a slotted body with an upper opening, the shape of which matches the cross-sectional shape of the strip-shaped object. Each side of the upper opening has an inwardly protruding edge to restrict the upward movement of the strip-shaped object. The bottom of the slotted body has at least one downwardly extending connecting pin. The slotted body is made of a plastic material with elastic deformation characteristics. The upper edge of the protruding edge has a guide surface to allow the strip-shaped object to be pressed downwards into the cavity of the upper opening under external human force.

[0007] Preferably, a positioning pin is provided at the bottom center of the upper opening to restrict the movement of the strip along the groove.

[0008] Preferably, the groove-shaped body is made of ABS material or PP or PE material.

[0009] Preferably, the lower edge of the convex edge is a stop plane perpendicular to the side of the upper opening.

[0010] Preferably, there are two connecting pins, each including a root portion near the groove-shaped body and a protruding pin portion located below the root portion. The lower part of the protruding pin portion is a lower guide portion with a guiding function. The diameter of the root portion is smaller than the maximum diameter of the protruding pin portion. The positioning pin portion is provided with an upper guide portion, which plays a guiding role when the strip is installed downwards.

[0011] Preferably, the thickness of the two sides of the upper opening is one-tenth to one-fifth of the height of the strip; the width of the stop plane is 0.5 to 1 times the thickness of the two sides.

[0012] This utility model discloses a bed, including a frame-shaped bed frame and bed slats disposed above the bed frame, and also includes a bed slat connector disposed between the bed slats and the bed frame, wherein the bed slat connector is the aforementioned groove-type connector; the lower fixing element is the bed frame, and the strip-shaped element is the bed slats.

[0013] Preferably, the bed slats include a longitudinally arranged center slat and several transversely arranged cross slats between the center slat and the side of the bed frame; a bed slat connector is provided between the cross slats and the center slat.

[0014] Preferably, the bed frame is provided with connecting holes corresponding to the connecting pins; the bed slats are provided with positioning holes corresponding to the positioning pins.

[0015] Preferably, the length of the groove-shaped body in its extending direction is one-third to one-half the width of the upper opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The grooved connector, through its grooved body with an upper opening and an inwardly protruding edge, enables the rapid installation and stable positioning of strip-shaped objects, preventing them from coming off upwards during use; the use of elastic plastic material and guide surface design allows the strip-shaped objects to be easily pressed into the installation, improving assembly efficiency and reducing the risk of damage; the grooved body is made of plastic material with elastic deformation characteristics, eliminating the need for screws or other mechanical fasteners when connecting with the lower fixing object and the strip-shaped object, achieving a drilling-free, rapid positioning, and self-locking assembly method on-site. This not only significantly simplifies the installation process of beds and similar structures but also reduces traditional defects such as screw loosening, installation errors, and material damage, which is conducive to improving production efficiency and product consistency.

[0017] Furthermore, the locating pins in the groove direction can prevent the strip from sliding back and forth in the groove, thereby improving the overall stability and service life of the structure, and are particularly suitable for applications such as bed slats.

[0018] Furthermore, by selecting ABS, PE, or PP materials, which combine elasticity, wear resistance, and impact resistance, production costs are reduced, and the flexibility and anti-aging properties of the connectors are improved, making them suitable for large-scale industrial injection molding production.

[0019] Furthermore, the convex edge is provided with a stop plane perpendicular to the side, which can form a reliable structural lock after the strip is installed, preventing it from loosening due to vibration or operating load, and effectively improving safety.

[0020] Furthermore, the addition of a double connecting pin and a lower guide section allows for rapid and precise insertion of the connector into the lower fixed object (such as a bed frame), enhancing the overall assembly's robustness and ease of repeated disassembly and assembly. The upper guide section of the positioning pin further optimizes the installation guidance of the strip, reducing human error.

[0021] Furthermore, by limiting the proportional relationship between the thickness of the two sides of the connector and the height of the strip and the width of the stop surface, a good balance between structural strength and elastic deformation is achieved, which improves the clamping force while avoiding material waste and the risk of damaging the strip.

[0022] Furthermore, the slotted connector is used for the fixed connection between the bed slats and the bed frame in the bed. It has a simple structure and is easy to disassemble and assemble, which solves the problems of cumbersome, loose and abnormal noise of traditional screw connection, and greatly improves the assembly efficiency and comfort of bed.

[0023] Furthermore, it can be used for multi-point distributed connections between longitudinal bed slats and transverse bed slats, effectively improving the overall stability of the bed board structure and adapting to various bed types and layouts, exhibiting good versatility and expandability.

[0024] Furthermore, the bed frame and strip are equipped with corresponding connecting holes and positioning holes, which can realize the accurate matching and positioning of the connecting parts, reduce deviations and structural misalignments, and facilitate mass standardized production and assembly consistency.

[0025] Furthermore, the ratio of the length of the groove body to the width of the upper opening can reduce the amount of material used, reduce weight and cost while ensuring connection strength, and also improve the appearance coordination and structural integration.
