DETAILED DESCRIPTION OF THE INVENTION
A first aspect of the present invention is a lid lock device for a lid body that is provided on an apparatus main body so as to be freely opened and closed, and is provided on one side of the lid body or the inner wall portion of the main body in the vicinity of the pivot axis of the lid body. The inner wall of the lock plate that is rotatably supported by the rotation support shaft and that is arranged in parallel with the rotation shaft of the lid, and the inner wall of the main body or the lid that opposes the position of the lock plate. and a lock spring which is arranged with a fixed interval, the closed state of the lid, constitute a tip portion of the lock plate to insert disposed between the lock spring and the inner wall portion, when the lid opening, wherein The lock plate moves while rotating with respect to the lid or main body on which the lock plate is supported by the rotation support shaft that rotates in conjunction with the rotation of the lid body about the rotation axis. As a result, the tip of the lock plate slides while contacting the lock spring, and the lid is opened. The state in which the cover body is configured to be retained at a fixed lid opening angle to the main body by the biasing force of the lock spring.
[0007]
Accordingly, the lock plate can be inserted and arranged between the lock spring and the inner wall portion in the closed state, and the lid body can be held at a certain angle in the open state by the action of the lock plate and the lock spring. When the lid is opened, the lock plate with respect to the lid body or the main body in which the lock plate is supported by the pivot shaft that rotates in conjunction with the rotation of the lid body about the pivot axis of the lid body. Can be moved while rotating, and can be configured in a very space-saving manner .
In the second invention, the lock plate and the lock spring are each formed with an engaging portion, and the lid body is held in an open state at an angle corresponding to each of the engaging portions by rotation of the lid body. By being configured, the lid can be reliably held open at the open position of the lid.
[0008]
Further, the third aspect of the invention provides a cover that can be rotated and supported at an arbitrary angle by changing the positions of the hooks of the lock spring provided on the main body and the lock plate attached to the cover. It has the effect | action which can carry out the rotation support of the cover body comprised so that it might be in a state at arbitrary angles.
[0009]
【Example】
Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of a lid-locking device according to the first embodiment of the present invention, and a perspective view in an opened state. 2 is a cross-sectional view of a main part showing the operation state of the apparatus, and FIG. 3 is an external perspective view of an apparatus including the apparatus.
[0010]
In the figure, an opening / closing lid 7 is attached to an apparatus main body 8 by a lid support shaft 9 so as to be freely opened and closed. In the vicinity of the side surface on which the lid support shaft 9 is provided, the lock spring 1 disposed at a certain distance from the inner wall portion 8a is disposed in the vicinity of the inner wall portion 8a of the main body 8, and the inner wall portion 7a of the opening / closing lid 7 has a fixed angle. 3 are fixedly mounted in parallel to the lid support shaft 9 by mounting screws 6 or the like. The fixed angle 3 is fitted with a lock plate 2 whose one side edge is rotatably supported by a rotation support shaft 5, and rotates together with the opening / closing lid 7. The lock plate 2 faces the inner wall 8a of the main body 8 and the lock spring 1 so that the lock plate 2 can be inserted into the gap when the cover is closed.
[0011]
The operation of the lid locking device configured as described above will be described below.
First, in the closed state of the open / close lid 7 indicated by a solid line in FIG. 2, the tip end portion of the lock plate 2 is inserted and disposed between the lock spring 1 and the inner wall portion 8 a of the main body 8. When the opening / closing lid 7 is opened from this state, when the opening / closing lid 7 rotates, the fixed angle 3 operates together, and the lock plate 2 attached to the fixed angle 3 has a tip between the main body 8 and the lock spring 1. The part moves so as to slide while contacting the lock spring 1. Then, the open / close lid 7 is pivoted to the open state indicated by the phantom line in FIG. 2, that is, to the position where the hook pieces 4a, 4b integrally provided at the tip ends of the lock spring 1 and the lock plate 2 face each other. At this time, the lock plate 2 is locked by the elastic force of the lock spring 1 so that the opening / closing lid 7 is held at a fixed opening angle with respect to the main body 8. FIG. 1 shows this open state.
[0012]
As described above, according to the present embodiment, the lock plate can be inserted and arranged between the lock spring and the inner wall portion in the closed state, and the lid body is fixed in the open state by the action of the lock plate and the lock spring. The structure in which the storage space A can be held at an angle can be configured in a very space-saving manner.
Further, it goes without saying that the opening / closing lid 7 can be held at an arbitrary angle by changing the positions of the locking pieces 4a, 4b of the lock spring 1 provided on the main body 8 and the lock plate 2 attached to the opening / closing lid 7. .
[0013]
Even if the lock spring 1 is provided on the inner wall 7 a of the opening / closing lid 7 and the fixed angle 3 and the lock plate 2 are provided on the inner wall 8 a of the main body 8, the same effects as described above can be obtained.
[0014]
【The invention's effect】
As described above, according to the present invention, there is provided a lid lock device for a lid body that is provided on the device main body so as to be freely openable and closable, and is provided on the lid body or the inner wall portion of the main body in the vicinity of the pivot axis of the lid body. The side edge is rotatably supported by a rotation support shaft, and the lock plate disposed in parallel with the rotation shaft of the lid body, and the main body or the inner wall portion of the lid body facing the arrangement position of the lock plate, An inner wall and a lock spring arranged at a predetermined interval, and in the closed state of the lid, the distal end portion of the lock plate is arranged to be inserted between the lock spring and the inner wall, and when opening the lid, The lock plate moves while rotating with respect to the cover body or the body on which the lock plate is supported by the rotation support shaft that rotates in conjunction with the rotation of the cover body about the rotation axis. As a result, the tip of the lock plate slides while contacting the lock spring. The open lid state in which the cover body is configured to be retained at a fixed lid opening angle to the main body by the biasing force of the lock spring.
[0015]
Accordingly, the lock plate can be inserted and arranged between the lock spring and the inner wall portion in the closed state, and the lid body can be held at a certain angle in the open state by the action of the lock plate and the lock spring. When the cover is opened, the lock plate is attached to the lid body or the main body in which the lock plate is supported by the rotation support shaft that rotates in conjunction with the rotation of the lid body about the lid rotation axis. It can be configured with extremely small space that it can move while rotating , and an advantageous effect for reducing the size and thickness of the device can be obtained.
