Description

Technical Field

[0001] This utility model belongs to the field of home use, and in particular relates to a new type of guardrail locking device and guardrail. Background Technology

[0002] To prevent infants and elderly people who are unable to care for themselves from falling out of bed, bed rails are often installed on the beds where these individuals sleep. Traditional bed rails are either fixed to the side of the bed, integrated with it, or added to the side of a regular bed. While integrated bed rails are effective in preventing falls, in practice, picking up an infant or moving an elderly person requires navigating around the fixed rail, making them inconvenient. Adding bed rails to regular beds also prevents falls, but most existing bed rails are flip-up or plug-in types, which are inconvenient to use, have poor load-bearing capacity, limited applicability, and are not compatible with mattresses of varying thicknesses. Therefore, on March 16, 2018, the applicant filed a patent application disclosing a "guardrail locking device and bed guardrail". This patent includes a fixed seat and a movable seat, connected by a pivot; the fixed seat has a fixing groove on its back, and a latch inside the fixed seat is positioned at the rear end of the fixing groove; a latch fixing plate is provided between the latch and the fixing groove, and a compression spring is provided between the latch fixing plate and the latch; the upper end of the latch has a hanging ear, and the latch is suspended from the fixed seat by the hanging ear. The end can swing freely; the upper end of the movable seat is provided with a longitudinal fixing rod, the side is provided with a transverse fixing rod, and the lower end is provided with a locking platform that cooperates with the latch; the middle of the movable seat is provided with a circular through hole, and a push rod is provided in the circular through hole. One end of the push rod is located at the latch outside the fixed seat, and the other end extends out of the circular through hole. An end with a size larger than the outer diameter of the through hole is provided outside the circular through hole, and this end contacts the latch. This solves the problems of inconvenient operation and poor load-bearing capacity of existing bed rails and improves the strength of bed rails. Although this patent solves the problems of traditional rail structure, in actual use, it is necessary to press the push rods simultaneously or separately to unlock, which is inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of guardrail locking device and guardrail, which solves the problem of inconvenient unlocking of existing guardrail locking devices and improves the convenience of use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel guardrail locking device, comprising a fixed seat and a movable seat, the fixed seat and the movable seat being connected by a pivot; a latch is provided on the back of the fixed seat; a longitudinal fixing rod is provided at the upper end of the movable seat, a transverse fixing rod is provided on the side, and a locking platform is provided at the lower end to cooperate with the latch; a circular through hole is provided in the middle of the movable seat, and a push rod is provided in the circular through hole, one end of the push rod being located at the latch and the other end being located on the outer side of the movable seat; a groove is provided on the push rod; the transverse fixing rod is a hollow rod, and a linkage mechanism is provided inside the hollow rod, one end of the linkage mechanism being provided with a lever and the other end being provided with a connector, the lever being placed in the groove.

[0005] This solution adds a linkage mechanism to the existing technology, which facilitates the combination of two opposing guardrail locking devices into a guardrail with a linkage unlocking operation. The linkage mechanism enables one-handed unlocking, solving the problem of inconvenient guardrail unlocking and improving ease of use.

[0006] Furthermore, the upper end of the hollow rod is provided with a notch, and the inner diameter of the hollow rod is orthogonally connected to the circular through hole. The linkage mechanism includes a linkage rod and a torsion spring. The linkage rod is placed inside the hollow rod, and one end of the torsion spring is fixed to the linkage rod, while the other end is engaged with the notch of the hollow rod.

[0007] The notch on the hollow rod facilitates the positioning of the linkage structure and provides convenience for fixing the torsion spring. The structure is simple and easy to use. After the external force is removed, the torsion spring can automatically reset the locking device.

[0008] Furthermore, the linkage rod is also equipped with a retaining spring, which is located at the end of the hollow rod.

[0009] The retaining ring is used to fix the linkage rod in the relative position between the hollow rods, and at the same time protect the torsion spring from falling off.

[0010] Furthermore, the linkage rod has a flange near its end, and the flange has a positioning pin on the side near the paddle. A torsion spring fixing groove is provided near the joint, and one end of the torsion spring is fixed in the torsion spring fixing groove.

[0011] Furthermore, the linkage rod is provided with an annular groove near the joint, and the retaining spring is installed in the annular groove and closely attached to the outer edge of the hollow rod.

[0012] The annular groove facilitates the installation of the retaining ring.

[0013] The second solution adopted by this utility model is: a new type of guardrail, including a railing, two new locking devices and a locking linkage mechanism arranged in opposite directions, the bottom ends of both sides of the railing are respectively fixed to the longitudinal fixing rods of the two new locking devices arranged in opposite directions; the locking linkage mechanism includes a connecting rod, two inner sleeves and a connecting pipe, one end of the two inner sleeves is respectively placed inside the two ends of the connecting pipe, each inner sleeve is provided with a pin penetrating the connecting pipe, the other end of the inner sleeve is respectively connected to the joint on the new locking device arranged in opposite directions, the connecting pipe is also provided with an outer sleeve, the outer sleeve is provided with an arc-shaped groove that cooperates with the pin on the inner sleeve.

[0014] Furthermore, the outer tube is provided with a handle, which is fixed to the outer tube.

[0015] Compared to the original guardrail, this solution provides greater stability and allows the outer sleeve to be moved by moving the handle. When the pin is in the arc groove on the outer sleeve, the handle can be rotated. Under the rotation of the lever, the latches on the two locking devices on the guardrail disengage from the locking platform, thus unlocking the guardrail. It is convenient to use and has a simple structure.

[0016] Furthermore, the connector is connected to the inner sleeve insertion structure.

[0017] The plug-in connection structure can accommodate dimensional errors between the locking linkage mechanism and the guardrail locking device, thus improving the connection strength.

[0018] When the handle is released, the locking linkage device resets under the action of the torsion spring, the push rod also resets under the action of the compression spring, and the latch engages with the locking platform, locking the device. Attached Figure Description

The movable seat has a circular through hole in its middle, and a push rod 7 is provided inside the circular through hole. One end of the push rod is located at the latch inside the fixed seat, and the other end is located outside the movable seat. The push rod has a groove. The transverse fixing rod is a hollow rod, and a linkage mechanism 28 is provided inside the hollow rod. One end of the linkage mechanism has a lever 11, and the other end has a connector 6. The lever 11 is placed in the groove 27.

[0031] As one embodiment of the present utility model, a paddle fixing structure 30 is provided at the end of the linkage rod, and the paddle 11 is mounted on the paddle fixing structure 30.

[0032] This solution adds a locking linkage mechanism to the existing technology, which facilitates the linkage unlocking of two opposing guardrail locking devices. Through the linkage operation of the unlocking device, the problem of one-handed unlocking is achieved, solving the problem of inconvenient guardrail unlocking and improving the convenience of use.

[0033] The hollow rod has a notch 10 at its upper end. The inner diameter of the hollow rod is orthogonally connected to the circular through hole. The linkage mechanism includes a linkage rod 28 and a torsion spring 32. The linkage rod 28 is placed inside the hollow rod. One end of the torsion spring 32 is fixed to the linkage rod, and the other end is engaged with the notch 10.

[0034] The notch on the hollow rod facilitates the positioning of the linkage structure and provides convenience for fixing the torsion spring. The structure is simple and easy to use. After the external force is removed, the torsion spring can automatically reset the locking device.

[0035] The linkage rod and the hollow rod are also provided with retaining springs 9 at their ends.

[0036] This retaining ring is used to fix the linkage rod in the relative positions between the hollow rods, while also protecting the torsion spring from falling off.

[0037] As a second embodiment of the present utility model: the linkage rod is provided with a flange 29 near the end, the flange 29 is provided with a positioning pin 25 on the side near the paddle 11, and a torsion spring fixing groove 31 is provided near the joint, one end of the torsion spring is fixed in the torsion spring fixing groove 31.

[0038] The linkage rod is provided with an annular groove near the joint, and the snap ring 9 is installed in the annular groove and closely attached to the outer edge of the hollow rod.

[0039] The annular groove facilitates the installation of the retaining ring.

[0040] like Figures 6-8 As shown, a novel guardrail includes a guardrail, two opposing novel locking devices, and a locking linkage mechanism. The bottom ends of the side rails on both sides of the guardrail are respectively fixed to the longitudinal rods 4 of the two opposing novel locking devices.
