Wheel device equipped with a fixing device having a quick stop function {WHEEL APPARATUS WITH FIXING APPARATUS}

This invention It relates to a wheel device equipped with a fixing device with a quick stop function. More specifically, it is installed on installation objects including industrial equipment, furniture, pianos, refrigerators, carts, etc. to enable smooth movement of installation objects. On the other hand, it relates to a wheel device equipped with a fixing device having a quick stop function to enable a temporary stop in the process of moving an installation object or fixation from a moved state quickly and stably.

In general, wheels are installed on heavy industrial equipment, furniture, pianos, refrigerators, etc. to facilitate transportation.

Such wheels rotate in the front and back directions and are configured to rotate 360 degrees in place, making it possible to transport objects with little force.

However, since conventional wheels are not fixed, there is a problem in that they can easily move when a worker or the like puts his or her hand in the process of transporting an object.

Accordingly, there is a problem of having to hold on to the object to be transported at all times.

As a prior art that partially improves this problem, Korean Utility Model Registration No. 20-0377809 (2005.03.08.) states that when the wheel is fixed, the height adjustment piece placed at the rear of the wheel moves up and down through rotation, causing the close support portion to be placed on the ground. A 'movable wheel with a fixed portion' whose movement is stopped by contact is disclosed.

However, such a conventional wheel has the problem of not only being inconvenient to operate, but also lengthening the time required for fixation, since the screw part of the height adjustment piece or the close support part must be directly rotated in order for the close support part to contact the ground.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings.

Referring to Figures 1 and 2, a wheel device (hereinafter referred to as "wheel device") 100 equipped with a fixing device with a quick stop function according to the present invention includes wheels 110 and is capable of moving an installation object. As a wheel device that allows this to be done smoothly, the body 120 has an open lower part and a wheel 110 is rotatably installed on the front, and a fixing bar 131 is coupled to the inside of the lower part of the body 120 to be able to move up and down. ) A fixing device ( 140) may be included.

Installation objects may include industrial equipment, furniture, pianos, refrigerators, carts, etc.

The installation target surface can be understood as an outdoor ground or an indoor floor.

The body 120 may have a cylindrical shape with an open bottom, and a pair of fixing protrusions 121 on which the wheel 110 is rotatably fixed may be formed on the front side.

The wheel device 100 may further include a fixed frame 150 rotatably fixed to the upper part of the body 120 and fixed to an installation object.

The body 120 is connected and fixed to the fixed frame 150 and a bearing, etc., and can be freely rotated relative to the installation object as the fixed frame 150 is fixed to the installation object.

The body 120 may have an operation hole 122 formed in the rear portion that communicates with the interior.

The fixing device 140 includes a rotary bar 141 with a fixing bar 131 screwed to the lower part and rotatably fixed to the upper part of the body 120, and a rotary bar 141 positioned in the operating hole 122. It may include an adjustment lever 142 fixed to the outside of.

The fixing bar 131 may be shaped like a metal cylinder and extends downward from the upper surface to form a fixing hole 131a into which the rotating bar 141 is screwed.

The fixing hole (131a) has a depth that allows the fixing bar (131) to be positioned above the wheel (110) while moving upward as the control lever (142) rotates from the state in contact with the installation surface, It may be formed to penetrate the lower surface of the fixing bar 131.

The rotating bar 141 may be rotatably fixed to the upper part of the body 120 by a bearing or the like.

The rotating bar 141 has threads formed on its outer peripheral surface, and the fixing bar 131 has threads formed on its inner peripheral surface forming the fixing hole 131a and can be screwed to the rotating bar 141.

The control lever 142 is located in the operation hole 122 and rotates as the user rotates it by hand, and the rotation bar 141 rotates together.

Referring to FIG. 3, the fixing bar 131 has a guide protrusion 132 extending in the vertical direction on the outer peripheral surface, and the body 120 has a guide groove 120a into which the guide protrusion 132 is inserted on the inner peripheral surface. This can be formed.

The fixing bar 131 guides the guide protrusion 132 in the longitudinal direction of the guide protrusion 132 without rotating with the rotating bar 141 when the control lever 142 is rotated as the guide protrusion 132 is retracted into the guide groove 120a. It can be.

Accordingly, the fixed bar 131 may be moved in the vertical direction according to the rotation of the rotating bar 141 and may be in contact with or spaced apart from the installation target surface.

That is, when the fixing bar 131 stops relative to the installation object, it moves downward according to the rotation of the control lever 142 and comes into close contact with the installation object surface, thereby preventing the installation object from moving due to external force. Accordingly, the installation object can be transported from a stopped state using separate transportation equipment, etc., as well as installed in a stopped state.

When moving the installation object, the fixing bar 131 moves in the upward direction according to the rotation of the control lever 142 and is spaced apart from the installation object surface to enable rotation of the wheel 110 by external force, etc. Accordingly, the installation object can be moved freely.

The fixing means 130 may further include a contact plate 133 provided at the lower part of the fixing bar 131 as shown in FIG. 4 .

The contact plate 133 may be made of a rubber material, etc., has a certain thickness, is in contact with the installation surface, and can prevent the fixing bar 131 from slipping.

As shown in FIGS. 4 and 5, the wheel device 100 includes a quick stop means 160 that moves the contact plate 133 downward to contact the installation target surface before rotating the control lever 142. More may be included.

The quick stop means 160 allows the contact plate 133 to quickly move downward and come into contact with the installation surface so that the installation object can be quickly stopped.

The quick stop means 160 can be used when a temporary stop or sudden stop is necessary during the movement of the installation object.

That is, the quick stop means 160 is a contact plate before the process of rotating the control lever 142 to bring the fixing bar 131 into contact with the installation target surface when a temporary stop or sudden stop is necessary during the movement of the installation object. (133) is in contact with the installation surface to enable quick stopping or quick movement after stopping.

To this end, a groove portion 131b communicating with the fixing hole 131a may be formed on the lower surface of the fixing bar 131 to be larger than the diameter of the fixing hole 131a.

The fixing bar 131 may have holes 131c formed on both sides that communicate with the groove portion 131b.

The quick stop means 160 includes a reinforcement plate 161 fixed to the upper part of the contact plate 133, a support bar extending upward from the reinforcement plate 161 and having fastening holes 162a penetrating both sides ( 162), the spring 163 accommodated in the groove 131b so as to be located on the outside of the support bar 162, and both ends pass between the fastening hole 162a and the upper and lower parts of the spring 163 and are in the hole 131c. It may include a locking bar 164 that is supported and one of the two ends protrudes to the outside of the fixing bar 131 through the hole 131c.

The body 120 may have a moving groove 123 into which the locking bar 164 is inserted while extending upward from the bottom on the other side or both sides.

The locking bar 164 may be introduced into the moving groove 123 as the fixing bar 131 is spaced apart from the installation surface and moves upward. For example, the locking bar 164 may be retracted into the moving groove 123 when the fixing bar 131 moves upward to its maximum extent.

The spring 163 is in a contracted state when both ends of the locking bar 164 are inserted into the hole 131c, and then as the locking bar 164 is pulled out from the hole 131c and the fastening hole 162a, in other words, As the locking bar 164 is separated from the fixing bar 131, it is relaxed and the reinforcing plate 161 can be pressed downward.

The upper part of the support bar 162 is preferably inserted into the lower part of the fixing hole 131a.

The support bar 162 may not be in contact with the rotating bar 141 when the fixed bar 131 is moved upward to its maximum extent.

The fixing bar 131 may have a step 131d protruding inward formed at the lower portion forming the fixing hole 131a.

The support bar 162 may have a flange 162a formed at the top that protrudes outward.

The support bar 162 moves downward as the locking bar 164 is separated from the fixing bar 131, while the movement may be stopped as the flange 162a comes into contact with the step 131d.

For example, when the support bar 162 is positioned on the same horizontal line as the lower part of the wheel 110, the contact plate 133 moves downward as the lock bar 164 is separated from the fixing bar 131. , the movement of the flange 162a may be stopped while contacting the step 131d.

Due to this, when the contact plate 133 is seated on the installation surface, the support bar 162 can support the contact plate 133 more stably while its upper part is located inside the fixing hole 131a.

The fixing bar 131 is lowered according to the rotation of the control lever 142 while the contact plate 133 is seated on the installation surface and is seated on the reinforcement plate 161, thereby enabling a safer stop.

The support bar 162 can be maintained in a locked state again by engaging the locking bar 164 through the hole 131c and the fastening hole 162a while the contact plate 133 is moved upward.

The wheel device 100 may further include a rotating part 170 for rotating the rotating bar using equipment as shown in FIGS. 7 and 8.

The rotary unit 170 may rotate the rotary bar 141 using equipment including an electric driver, separately from the control lever 142, to raise and lower the fixed bar 131.

The rotating portion 170 includes a worm 171 whose both ends are rotatably fixed to both sides of the body 120, a worm gear 172 fixed to the rotating bar 141 and tooth-coupled with the worm 171, and the worm 171. It may include a coupling member 173 that is coupled to one end and has a coupling groove 173a through which the equipment is coupled.

The worm 171 can cause the fixed bar 131 to move up and down as the rotating bar 141 rotates horizontally, that is, in the front-back direction, as it rotates vertically, that is, in the up-and-down direction.

The coupling member 173 may protrude to the outside of the body 120, and the worm 171 and the worm gear 172 may be rotated using equipment.

That is, the rotating unit 170 can enable the fixing bar 131 to move up and down quickly with little force using an electric screwdriver or the like in situations where it is difficult to operate the control lever 142.

Due to this, the rotating part 170 not only solves the difficulty of operating the control lever 142 while lifting the heavy installation object when the installation object is stopped, but also provides the power required to rotate the control lever 142. It can help you save time.
