Abstract
The utility model discloses a kind of adjustable height castors, support frame including being provided with runner, screw rod is provided at the top of support frame as described above, connection frame, adjusting nut and lock nut are successively socketed on the screw rod, the connection frame is fixedly connected on device bottom, the adjusting nut upper socket is rotatedly connected in connection frame and with connection frame inner surface, rotor is provided on the rotation connection face, adjusting nut inner surface is spirally connected with screw rod to be connected, and the lock nut below adjusting nut, which is also spirally connected with screw rod, to be connected.The utility model mentions that structure is simple, and easy to use, adjustable range is big, and in equipment needed for reserved installation space it is smaller, be particularly suitable for compact type equipment use, simultaneously, since its adjusting nut is located on runner, adjust castor height when it is unrestricted, flexibly and easily.
Description
Technical field
The utility model relates to castor technical fields, more particularly, to a kind of adjustable height castor.
Background technique
The adjustable castor of present level is usually the installation and adjustment footed glass on the connection frame of universal wheel or foot wheel carrier steering shaft,
Castor height is adjusted by adjusting the flexible of footed glass.Since footed glass is relatively large in diameter, wheel subcenter axis and foot wheel carrier is caused to turn to
The distance between axis is larger, and the stress arm of force of foot wheel carrier is longer, therefore the pressure that foot wheel carrier can bear in the case of equivalent material
It is smaller；Secondly, operation is more difficult when adjustment levels footed glass height when wheel gear is when leveling before footed glass；In addition, above-mentioned knot
The castor needs of structure reserve biggish installation space in equipment, therefore are not suitable for compact type equipment.
Summary of the invention
The utility model provides a kind of adjustable height castor, it is therefore intended that solve existing castor pressure-bearing is small, it is inconvenient to adjust,
The problem of being not suitable for compact type equipment.
To achieve the above object, the utility model can take following technical proposals:
Adjustable height castor described in the utility model, the support frame including being provided with runner, support frame as described above top
It is provided with screw rod, connection frame, adjusting nut and lock nut are successively socketed on the screw rod, the connection frame is fixedly connected on
Device bottom, the adjusting nut upper socket are rotatedly connected in connection frame and with connection frame inner surface, the rotation connection
Rotor is provided on face, adjusting nut inner surface is spirally connected with screw rod to be connected, the lock nut below adjusting nut
It is spirally connected and is connected with screw rod.
The roller centre axis and screw rod central axis are located in Different Plane, carry out universal rotational convenient for runner.
The adjusting nut top is provided with annular groove, is provided on the connection frame and matches with the annular groove
Annular snap, the rotor is arranged in the annular snap lower surface and adjusting nut joint, to make adjusting nut and connection
Frame keeps relatively stable, smooth rotation connection structure.
Adjustable height castor provided by the utility model, structure is simple, and easy to use, adjustable range is big, and in equipment
Upper required reserved installation space is smaller, is particularly suitable for the use of compact type equipment, simultaneously as its adjusting nut is located at
On runner, adjust castor height when it is unrestricted, flexibly and easily.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the attachment structure schematic diagram of adjusting nut and connection frame in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, adjustable height castor described in the utility model, the support frame 2 including being equipped with runner 1,
Screw rod 3 is installed at the top of support frame 2, connection frame 4, adjusting nut 5 and lock nut 6, the connection frame are successively socketed on screw rod 3
4 are fixedly connected on device bottom, and bottom is provided with annular snap, and 5 top of adjusting nut is provided with to match with 4 annular snap of connection frame
The annular groove of conjunction, the two connect together, and for flexible rotating, pacify in annular snap lower surface and 5 joint of adjusting nut
Equipped with rotor 7, the inner surface of above-mentioned adjusting nut 5 is spirally connected with screw rod 3 to be connected, the lock nut 6 positioned at 5 lower section of adjusting nut
It is spirally connected and is connected with screw rod 3.1 central axis of runner and 3 central axis of screw rod are located in Different Plane, can make runner 1 more flexiblely
Realize universal rotational.
When needing to turn down castor height (even if Distance Shortened of device bottom and ground), it is only necessary to rotate clockwise adjusting spiral shell
Mother 5 rises screw rod 3, so that runner 1 be made to rise, reduces castor height, after reaching adjusting target, rotates counterclockwise locking
Nut 6 keeps it mobile to 5 direction of adjusting nut and tightens after being adjacent to adjusting nut 5, prevents screw rod 3 from loosening.
Conversely, when needing to be turned up castor height (even if device bottom increases at a distance from ground), it is only necessary to when move counterclockwise
Adjusting nut 5 declines screw rod 3, so that runner 1 be made to decline, promotes castor height, after reaching adjusting target, turns counterclockwise
Dynamic lock nut 6 makes it to lock adjustment nut 5, prevents screw rod 3 from loosening.
