Description

[Detailed description of the invention] Industrial application field This invention is a locking device for a fence post that prevents the passage of vehicles, etc. by pulling out a pole from an outer cylinder buried underground and setting it up on the ground, that is, a pole. This invention relates to a device that prevents unnecessary immersion of the device and maintains the upright state.

Conventional technology Conventionally, this type of locking device was installed for the purpose of preventing the pole from unnecessarily sinking into the outer cylinder, so it was usually installed near the ground surface of the fence post, and its operating section It was also close to the ground.

Problems that the invention aims to solve: For this reason, when locking the pole by setting it upright or unlocking it by inserting it into the outer cylinder, it is necessary to bend down each time to operate it, and a large number of locks are required. Handling fence posts required a great deal of effort.

Means for Solving the Problems The present invention was devised to eliminate the drawbacks of the conventional method, and includes an outer cylinder 1 buried underground, a pole 2 inserted into the outer cylinder 1 so as to be freely retractable. An engaging body 4 is provided on the upper inner side of the outer cylinder 1 in order to erect the pole 2 on the ground, and a guide groove 4', which is fixed and protrudes through the lower part of the pole 2 and bent into a hook shape, is provided on the engaging body 4. In the fence post which can freely appear and retract from the ground, the fence post is equipped with a support 3 that holds the pole 2 in an erected state by being locked to the support 3, and a stopper main body 5 is attached to the support 3 so as to be movable forward and backward along the support 3. and a stopper 6 that protrudes from one side of the stopper main body 5, is superimposed on the upper part of the support body 3, moves forward and backward at a constant interval, projects from the pole 2, and is locked to the engaging body 4, and the forward and backward directions of the stopper 6. A pin 10 protruding in the horizontal direction perpendicular to
an elevating body 8 which forms an oblique groove 9 into which a pin 10 is fitted and holds the stopper main body 5; and an elevating body 8 connected to the elevating body 8 by a linking body 13 and provided above the pole 2 an operating mechanism 12 for raising and lowering the
It consists of an operating section 14 of an operating mechanism 12 facing the outer peripheral surface of the pole 2.

Function: By operating the operating portion 14 on the upper outer peripheral surface of the pole 2 erected on the ground, the elevating body 8 is raised or lowered via the connecting body 13 and maintained in that state. As the elevating body 8 rises or descends, it presses the pin 10 fitted in the diagonal groove 9 in the direction of the stopper 6, moves the main body 5 and the stopper 6 along the support body 3, and moves the engaging body 4. When unlocking the lock by protruding from the pole 2 above the support 3 which is locked in the hook-shaped guide groove 4', the elevating body 8 is lowered or raised. The pin 10 is pressed in the retracting direction, the stopper 6 is accommodated in the pawl 2, the support body 3 can pass through the guide groove 4', and the pawl 2 can be retracted into the outer cylinder 1.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an outer cylinder buried underground, into which a pole 2 erected above the ground is inserted so as to be freely retractable. Reference numeral 3 denotes a supporting member which is fixedly penetrated through and protrudes from the lower part of the pole 2, and is engaged with a guide groove 4' bent into a hook shape of an engaging member 4 provided on the upper inner side of the outer cylinder 1, so that the pole 2 can be erected. Retain state. Reference numeral 5 denotes a stopper main body attached to the support 3, which is movable back and forth along the support 3. A stopper 6, which is protruded from one side of the stopper and overlaps the upper part of the support 3 and moves back and forth at a constant interval, is a pole. It can be freely entered and exited through the window hole 7 of No. 2. 8
is an elevating body that holds the stopper main body 5, and is formed with a diagonal groove 9 whose lower side is in the direction of the stopper 6, and a diagonal groove 9 is provided with a protruding part in a direction perpendicular to the advancing and retracting direction of the stopper main body 5. A pin 10 is movably fitted therein. 11 has the upper end attached to the support body 3;
The springs whose lower ends are respectively connected below the elevating body 8 apply a force to push down the elevating body 8 and maintain the stopper 6 in the retracted state. Reference numeral 12 denotes an operating mechanism provided at the upper part of the pole 2, which has a mechanism for raising and lowering the linking body 13 connected to the elevating body 8 and maintaining the raised state. I'm letting you do it. This operating mechanism 12 consists of a cam 15 that rotates when the operating section 14 is rotated, and an elevating piece 16 that moves up and down with the rotation of the cam 15.
The lifting piece 16 has a bent piece 1 at the upper end that contacts the cam 15.
7 and the lifting piece 1 by preventing excessive rotation of the cam 15.
6, and a stop piece 18 that maintains the raised state, and a connecting body 13 is connected to the lower end. 19 is Paul 2
20 is the operating mechanism 1.
This is the second mounting plate.

In this embodiment, the stopper 6 is designed to protrude when the elevating body 8 rises, but the oblique groove 9
By reversing the direction of inclination, the structure is such that it protrudes when the elevating body 8 descends. Furthermore, the position of the spring 11 that maintains the stopper 6 in the retracted state is not limited to the embodiment.

Effects of the invention As mentioned above, the invention is based on an outer cylinder 1 buried underground.
Since the stopper 6 is superimposed on the upper part of the support body 3 that is engaged with the hook-shaped guide groove 4' of the engagement body 4 and moves back and forth at a constant interval, the stopper 6 can be moved back and forth in the locked state. 6
can restrict the movement of the support body 3 and prevent unnecessary sinking of the pole 2. Since the operating part 14 of the stopper 6 faces the upper outer peripheral surface of the pole 2, there is no need to bend down each time the pole 2 is locked or unlocked, and can be operated while standing. This makes it convenient for handling a large number of fence posts.

Further, by providing a spring 11 that pushes down the elevating body 8, the elevating body 8 can be lowered smoothly and quickly, and the movement of the stopper 6 and the locking or unlocking can be ensured.

As described above, the present invention is simple in structure and handling as a locking device for a fence post that can be freely retracted from the ground, and has various effects such as reliable locking.
