Detailed Description
The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.
The present application provides a rotationally lockable connection as shown in fig. 1, comprising: the locking device comprises a first locking member 10, a second locking member 30 and a locking member, wherein the first locking member 10 is hinged with the second locking member 30, and the locking member is arranged on the first locking member 10 and is interlocked with the second locking member 30.
Specifically, the first locking member 10 has a housing, one side of the housing is configured with an accommodating cavity 101, the accommodating cavity 101 is provided with an opening, the opening is internally sleeved with a key 20, the key 20 is slidably configured in the opening, and the key 20 has a first inclined surface extending into the accommodating cavity 101; the second locking member 30 is rotatably coupled to the housing by a rotating shaft 60; the locking member is basically configured in the accommodating cavity 101, the locking member comprises a locking bolt 40 movably installed in the accommodating cavity, one end of the locking bolt 40 is connected with the inner wall of the accommodating cavity 101 through a spring 50, the other end of the locking bolt 40 is pushed by the spring 50 to lock the second locking member 30, when the locking bolt 40 is in contact with the second locking member 30, the second locking member 30 cannot rotate, a second inclined surface abutted against the first inclined surface is further arranged on the locking bolt 40, and the first inclined surface is in slidable contact with the second inclined surface.
As shown in fig. 3, when the first locking member 10 and the second locking member 30 are locked, the first inclined surface and the second inclined surface are staggered and only partially overlap to support the normal use of the button 20, and the tension of the spring 50 pushes the locking tongue 40 to be inserted into the second locking member 30, so that the second locking member 30 cannot rotate.
As shown in fig. 4, when the key 20 is pressed, the key 20 slides into the accommodating cavity 101, and during the sliding process, the area of the first inclined surface and the second inclined surface which are overlapped alternately increases, and the first inclined surface pushes the second inclined surface to move in the direction away from the second locking member 30, so that the spring 50 is compressed, and the locking tongue 40 is disengaged from the second locking member 30. After key 20 is released, spring 50 is extended to push locking bolt 40 to extend toward second locking member 30, and the contact overlapping area of the first inclined surface and the second inclined surface is reduced during the extension process, that is, the top end of the first inclined surface is close to the bottom end of the second inclined surface, as shown in fig. 3.
In one embodiment, as shown in fig. 2 to 4, the housing of the first locking element 10 is extended with a sleeve, which can be used for connecting and fixing a longer connecting element, or it is possible that the housing is directly shaped as a longer connecting element. The housing also has outwardly extending arms (not shown) that cover at least the junction of the second locking member 30 and the housing (first locking member 10) and prevent foreign objects from entering the junction from above and being caught.
In one embodiment, as shown in fig. 3-4, second locking member 30 is provided with a limiting groove 302, and when the protruding portion of locking bolt 40 is pushed into limiting groove 302 by spring 50, the protruding portion of locking bolt 40 cooperates with limiting groove 302 to limit rotation of second locking member 30; when the locking tongue 40 is separated from the limiting groove 302, the second locking member 30 can rotate relative to the first locking member 10.
Further, the second locking member 30 includes a rotating portion and a connecting portion 301, the limiting groove 302 is provided on the rotating portion, the rotating portion 301 is rotatably connected to the housing, and the connecting portion 301 and the rotating portion are integrally formed. As shown in fig. 2, the connection portion 301 may be a structure like a sleeve.
Although the first locking member 10 and the second locking member 30 can rotate relatively, the end portions of the relative rotation are generally provided with arc transition surfaces, and the end surfaces are rectangular or other shapes, which do not affect the relative rotation of the first locking member 10 and the second locking member 30, but here, the end portions of the second locking member 30 opposite to the first locking member 10 are preferably arc.
The present application also provides a bed fence as shown in fig. 2-4, comprising a connecting rod for lateral support, the connecting rod comprising a first section 701 and a second section 702 connected by a rotational lockable connection, the first section 701 being connected with the connection portion 301 of the second locking member 30 by a fixing pin 100, the second section 702 being connected with the first locking member 10 by a fixing pin 100. It can be stated that the connecting portion 301 and the receiving cavity 101 can be of a similar sleeve-like construction for connecting and fixing the first locking element 10 and the second locking element 30, respectively, to the connecting rod.
The bed guardrail structure has the beneficial effects that: the rotary connecting piece is added in the middle of the connecting rod, when the bed guardrail is unfolded, the locking structure is in a locking state, and the connecting rod cannot be easily folded; when locking structure is in the unblock state, the connecting rod just can be folded, and such structure makes whole bed guardrail can exempt from to tear open foldingly to reduce the packing volume of bed guardrail, reach the function that the bed guardrail main part exempted from the installation.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
