The present invention relates to a clamping device, and more particularly, to a clamping device, and more particularly, to a clamping device capable of easily moving and fixing a training material to a desired position on a training table in the form of a profile plate, And more particularly, to a clamping device for a training material which can improve an exercise effect by precisely clamping even if the height of the training table is different or the thickness of the slot groove is different.

In general, students studying science and technology and practitioners such as research and development acquire skills through various experiments and exercises.

As an example, various electrical and electronic equipments are used together with pneumatic and hydraulic equipment as an automation system, and these equipments are experimented with equipments and they are operated under realistic conditions through experiments or experiments.

In this way, in order to fix the training device to the training table, the clamping device is firmly fixed to the table to prevent the equipment from slipping and the like, thereby conducting experiments and exercises.

In the conventional clamping apparatus, there are a patent registration No. 10-459291 (one-touch clamping apparatus for practice materials), a patent registration No. 10-812991 (clamping apparatus), a patent registration number 10-664976 (Clamping device for laboratory practice), and 10-746748 (Practice material fixing assembly).

The clamping device of Patent Registration No. 10-459291 includes a clamping rotating body and a connecting rotating body inside the main body, wherein the clamping rotating body and the connecting rotating body form mutual gear portions so that the gear portions are engaged and interlocked with each other.

At this time, a lever is provided at one side of the connecting rotating body, and a clamp element is provided at the lower end of the clamping rotating body. In the clamping device having the above-described structure, the clamping rotary body is rotated by rotating the lever in the direction of about 90 °, and the clamping lance formed at the lower end is rotated and clamped inside the training table, thereby fixing the training device.

The clamping device having the above structure has a problem in that it can not be quickly clamped because it can perform lock / unlock by hand, and there is also a problem in that a malfunction occurs because the gear is made of a gear type so that the gear is continuously broken during repeated use.

In order to place the clamping element at the correct position on the table, there is a problem in fixing the clamping element in the correct position on the training table since the clamping element should be initially positioned at the right angle and there is no alternative means to place it in the correct position.

In addition, such a clamping device has a problem that the productivity is deteriorated because two or more component elements of the pivoting member are formed, and such a problem poses a problem of raising the unit price of the product.

Further, the slot groove of the training table on which the clamping device is fixed is formed in the longitudinal direction with a small width to allow the clamping element to flow in. However, since the clamping element of the clamping device has different widths in the right and left direction, have.

The clamping device of Patent Registration No. 10-812991 includes an operating member having a plurality of operating protrusions in a circumferential direction with the lever inwardly of the main body, and the plate spring is pushed by the rotation of the operating member to be rotated at a predetermined angle Clamping elements are provided to effect clamping.

Such a clamping device is inconvenient in use because it performs locking / unlocking by manual operation as in the above-mentioned problems, and there is a problem that productivity is deteriorated due to a large number of parts, and it is impossible to use in both directions. So that it is inconvenient to install it on the training table.

The clamping device disclosed in Japanese Patent No. 10-664976 includes a gear type rotating body having a clamp element at the lower end thereof in the body and meshing with the rotating body at both ends of the gear type rotating body so that one side is advanced, So that clamping is performed.

Such a structure also has a problem that it is inconvenient to use due to manual locking / unlocking, and there is a problem that the clamping element formed at the lower end is different in width from left to right so that clamping can be used only in one direction, not in both directions. There is a problem in that the gears are broken during use and malfunctions occur.

In addition, there is a problem that the clamping element can not be firmly fixed to the training table because the clamping element is formed as a single body. Particularly, such a clamp has a problem that the gear- will be.

The clamping device of Patent Registration No. 10-746748 includes a movable member and a clamping element housed in the body, and the clamping element is clamped while being reciprocated diagonally by pressing of the movable member. When the movable member is released, So that the movable member is returned to the original position.

Such a clamping device can also be used only in one direction, not in both directions, so that it is inconvenient to use, and there is a problem that the structure is complicated and the productivity is lowered and the unit price of the product is increased.

In addition, since four or more springs are provided, in order to clamp the movable member, the moving force of the movable member doubles.

Further, since there is no element for selecting a position for inserting the clamping element into the slot groove of the table, it is very inconvenient when it is mounted.

The biggest problem of the conventional techniques is that the height of the slot is different and the height of the slot is different, or two of the slot protrusions of the slot groove can not be fixed to the other table.

The clamping device can not be fixed to the table in which the insertion protrusions of the height and the slot groove are different from each other, so that the exercise equipment can not be attached to the table.

(Example)

The clamping device 100 according to the present invention includes a main body 110, an operating body 120 incorporated in the main body, and a locking / unlocking mechanism 130 mounted on the slot groove 11 of the training table 10, And a canceling main body 130.

The width of the lever operating chamber 111 and the width of the rack operating chamber 112 are set such that the lever operating chamber 111 and the rack operating chamber 112 communicate with each other when the rack gear is moved It is preferable that the pinion gear is operated so that the clamping element 132 provided at the lower end is rotated by 90 degrees.

And a pinion inner chamber 113 for receiving a pinion is provided on both sides of the front end of the rack operation chamber 112. The spacing between the pinion inner chamber 113 and the pinion inner chamber 113 is determined by the interval between the slot grooves 11 of the table It is preferable that they are formed at equal intervals.

The concave portion of the pinion interior chamber 113 is preferably provided so as to communicate with the rack operation chamber 112 so that the pinion gear and the rack gear are engaged with each other.

On the other hand, the lower end of the main body 110 is preferably provided on the training table 10 so as to have a moving directional region 114 for preventing vibration and slippage from the center front and back of the horizontal width.

On the other hand, the actuating body 120 is seated in the lever operating chamber 111 and the rack operating chamber 112, and the lock / unlock main body 130 is built in the pinion internal chamber 113.

The operation member 120 is provided with an operation lever 121, and a rack gear 122 is provided in front of the operation lever. At this time, the rack gear may be provided with a front gear in front of the rack gear, or may be provided with only a section where the pinion is rotated to be engaged with the rack gear.

The lock / unlock main body 130 is installed in the pinion internal chamber 113. The lock / unlock main body 130 has a clamping element 132 at the lower end thereof. The upper end of the lock / (131).

Meanwhile, the pinion built-in chamber is provided with a tension member 150, and a seating hole 113a and a protrusion wall 113b are formed to prevent the tension member from being received and removed.

That is, the tension member 150 is accommodated in the seating hole 113a, and the lock / unlock body 130 is seated on the upper end, so that the pinion gear and the rack gear are engaged with each other.

When the clamping device is mounted on the training table, the tension member 150 may be displaced in the height direction of the tension member when the clamping device is mounted on the training table, 150 are compressed and the clamping element is rotated and clamped in the slot groove, so that clamping is required.

And a cover 200 covering the lock / unlock main body 130 and the actuating body 120 is installed at the upper end of the main body 110.

An intermittent groove 121a is formed at both sides of the lever and an intermittent ball 140 for interrupting the intermittent groove 121a is provided at the center of the lever operating chamber 111 when the lever is operated.

Preferably, the intermittent ball 140 is formed in a straight line with the leading end portion of the fluid chamber 114 (the fluid chamber located at the lower end of the lever) before and after the lower end.

That is, the intermittent ball 140 constitutes a groove 111a in the center of the lever operating chamber 111, the intermittent ball 140 flows in the lower end thereof, the spring S is built in the lower end thereof, The intermittent ball 140 is prevented from being dislodged.

The intermittent ball 140 is configured to flow into the intermittent groove 121a formed in the lever in a state in which the lever is operated to prevent the lever from flowing due to vibration or mistake.

The distance of the intermittent groove 121a provided at the lower left and right sides of the lever 121 is set to a distance such that the rack gear rotates the pinion and the clamping element 132 provided at the lower end of the pinion gear is rotated exactly 90 degrees .

On the other hand, it is preferable that the distance between the clamping elements 132 and the distance between the fluid-dynamic regions are maintained at the same interval as the slot groove 11 formed in the training table.

At the lower end of the rack gear rack gear 122, a long hole 122a is provided in the longitudinal direction. The rack operation chamber is provided with an interlock protrusion 126 protruding from the long hole to interrupt the long hole.

Hereinafter, the operation and operation of the clamping device 100 having the above-described configuration will be described.

In order to fix the training material to the training table using the clamping device 100 of the present invention, the clamping device 100 is positioned at the upper end of the training table 10, The clamping device may be fixed to the training table by pushing the lever 132 inserted into the slot groove 11 and operating the lever 121.

At this time, since the fluid-dynamic region 114 is inserted into the slot groove 11 formed in the left-right direction in the longitudinal direction, the clamping elements provided on the same line can be easily inserted into the slot groove 11.

On the other hand, when the lever is on the left side of the operation chamber, the clamping element 132 is positioned so as to easily enter the slot groove.

When the lever 121 is moved to the right in this state, the rack gear is moved to the right side while the lever is squeezing and lowering the intermittent ball. When the pinion gear engaged with the lever rotates and the lever is completely pressed to the right side, And the clamping element 132 provided to be interlocked with the lower end is also tightly fixed to the inner wall of the slot groove in a state rotated by 90 degrees.

At this time, the pressurized intermittent ball 140 is raised by the tension force of the spring, and flows into the intermittent groove 121a provided on the left side of the lever to prevent the movement to the left side of the lever.

Further, since the slot and the protrusion 126 are formed at the lower end of the rack gear, the rack gear is prevented from further moving, so that accurate clamping can be performed.

In particular, as shown in Figs. 6A and 6C, the slot groove fitting projections 12 of the training table are different from each other on the training table. As described above, there is a problem that the clamping device can not be mounted on a table having different fitting protrusions.

For example, when the fitting protrusion 12 of the slot groove is 5 mm, the upper catch of the clamping element must be exactly coincident with 5 mm so that it can be mounted without shaking. In the case of having a thickness of 5 mm or more of the fitting protrusion, the clamping device having the hook portion of 5 mm can not be mounted at all, making it impossible to mount the training material.

However, in the clamping device of the present invention, even when the projections of the clamping device are different from each other, since the lock-releasing main body 130 is lowered while being tightened while compressing the tension member 150, So that the clamping device does not shake or the like.

Also, since the exercise table is in a fixed state, the position of the exercise table can not be modified because the height of the slot groove is different.

Therefore, as shown in the accompanying drawings, even if the practice table 10 and the fitting projections d1 and d2 of the slot grooves of the shist table 10-1 are mounted on different tables, Since the member is compressed and the clamping element is rotationally mounted, accurate mounting can be performed, and vibration or the like is prevented because the clamping element is mounted by the tension member.

6C, in the divided exercise table, the height of the divided exercise table may be different from each other, and the tables having different height d3 are also mounted by the degree of compression of the tension member So that the clamping device of the present invention has an advantage that clamping can be performed accurately without applying the above-mentioned problem of sticking.

The specific embodiments of the present invention have been described above.

It should be understood, however, that the spirit and scope of the present invention are not limited to these specific embodiments, but that various modifications and changes may be made without departing from the spirit of the present invention. You must understand.

Accordingly, it should be understood that the foregoing embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Are only defined by the scope of the claims.
