Description

Two-section rotary supporting foot

Technical Field

The utility model belongs to hold in the palm the foot field, specifically be a rotatory support foot of two sections.

Background

The function of the foot rest is mainly to support the load in the upper step. With the progress of the times, the support legs commonly used at present generally consist of a support bottom, a threaded rod and a support seat, wherein the support seat is in threaded connection with the threaded rod, so that the height of the support seat can be adjusted, and the load in the previous step frame can be conveniently adjusted to be in a horizontal state.

Then, as the supporting seat is fixedly connected with the load in the previous step, the height of the supporting seat is adjusted by lifting the load to rotate the support base and the threaded rod. If the load on the supporting seat is heavy, the lifting of the load rotating support bottom and the adjustment of the threaded rod are laborious, and therefore, a two-section rotating support foot is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: if the load on the supporting seat that proposes in solving above-mentioned background art is heavy, lift up the rotatory end of holding in the palm of load so and the threaded rod is adjusted then comparatively hard problem, the utility model provides a rotatory foot that holds in the palm of two sections.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a two sections are rotatory holds in palm foot, includes that the support end, vertical threaded rod and the supporting seat of threaded connection on the threaded rod top of fixing at the end top middle part of holding in the palm, the cross section of supporting seat is the annular, and the top of supporting seat is provided with bearing and its grafting in the inner circle of bearing, the top of bearing is provided with rather than outer lane fixed connection and be telescopic branch, branch includes that the bottom is fixed with the outer lane of bearing and has the internal screw thread sleeve pipe, sheathed tube top threaded connection has the loop bar that has the external screw thread, the top of loop bar be used for with load fixed connection.

Furthermore, the outer peripheral side of the support bottom is in threaded connection with a plurality of threaded knobs which are distributed in an equally-spaced annular mode and located in the horizontal direction, and the bottom end of a rotating handle on each threaded knob is located at the same horizontal position as the bottom end of the support bottom.

Furthermore, a first groove is formed in the middle of the bottom end of the support bottom, and a cushion for shock absorption is connected in the first groove.

Further, the soft pad comprises a latex pad.

Further, the soft pad comprises one or more of a rubber pad and a cotton pad with the elasticity and softness similar to those of the latex pad.

Furthermore, a plurality of second grooves which are distributed in an equidistant annular mode are formed in the bottom end of the support bottom, the first grooves are located among the second grooves, and anti-skid pads are connected into the second grooves.

Further, the height of the threaded rod is lower than that of the supporting seat.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, peg graft in the inner circle of bearing on the top of supporting seat, and the outer lane fixed connection of sheathed tube bottom and bearing, like this, after loop bar and load fixed connection lived, the inner circle of bearing, a supporting seat, the threaded rod can be regarded as a whole A with holding in the palm the end, loop bar and load can be regarded as another whole B, and because sleeve bar and loop bar are threaded connection, so, when rotary sleeve, the outer lane of sleeve pipe and bearing rotates together, whole A keeps motionless, and whole B can rise gradually or descend, to sum up, through such setting, the regulation of this device height is realized to the rotatory cover pipe of accessible, need not hard lift the load and adjust at the end of rotatory support.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The two-section rotary support leg provided by the present embodiment, as shown in fig. 1, comprises a support base 1, a threaded rod 2 vertically fixed in the middle of the top end of the support base 1, and a support base 3 screwed on the top end of the threaded rod 2, because the support base 3 is a connecting pipe with a downward opening, the cross section of the support base 3 is ring-shaped, a bearing 4 is arranged on the top end of the support base 3, the support base 3 is inserted in the inner ring of the bearing 4, a telescopic supporting rod 5 fixedly connected with the outer ring of the bearing 4 is arranged on the top end of the bearing 4, the telescopic supporting rod 5 comprises a sleeve 51 with a bottom end fixed with the outer ring of the bearing 4 and an inner thread, a sleeve 52 with an outer thread is screwed on the top end of the sleeve 51, the top end of the sleeve 52 is used for fixedly connecting with a load, so that the support base 1, the threaded rod 2, the, the load and the sleeve lever 52 are viewed as another body B, and when the sleeve 51 is rotated, the sleeve 51 and the outer ring of the bearing 4 rotate together because the outer ring of the bearing 4 and the sleeve 51 are fixed, while the body a remains stationary, and the body B moves up and down because of the threaded connection with the sleeve 51.

Because the stress area of the support base 1 is limited, the stability of the load on the support base 1 cannot be maintained only by the support base 1, therefore, in order to enhance the stability of the support base 1, as shown in fig. 3, a plurality of thread knobs 6 which are distributed in an equally spaced annular shape and are located in the horizontal direction are connected to the outer peripheral side of the support base 1 in a threaded manner, and the bottom end of a rotating handle on each thread knob 6 is located at the same horizontal position as the bottom end of the support base 1.

If the whole supporting foot and the load fall accidentally under the lifted state, the supporting foot is impacted on the ground and can be damaged greatly, so that in order to protect the supporting foot, as shown in fig. 4, a groove I7 is formed in the middle of the bottom end of the supporting bottom 1, a cushion 8 for shock absorption is connected in the groove I7, and the cushion 8 can be a latex cushion or one or more of a rubber cushion and a cotton cushion similar to the elasticity and the softness of the latex cushion.

As shown in figure 4, a plurality of second grooves 9 which are distributed in an equidistant annular mode are formed in the bottom end of the support base 1, the first grooves 7 are located between the second grooves 9, the anti-skid pads 10 are connected into each second groove 9, and the anti-skid pads 10 can not only play a role in skid resistance, but also play a better shock absorption role in cooperation with the soft pads 8.

The utility model discloses in except can adjusting holistic height through rotatory sleeve 51, also can carry out the regulation of height through the mode of rotatory support end 1 and threaded rod 2 under the light condition of load, but when using this kind of mode to adjust, need fix supporting seat 3 temporarily, in addition, for preventing that threaded rod 2 from influencing sleeve 51, the utility model provides a threaded rod 2 highly is less than supporting seat 3's height.
