Abstract

The utility model discloses a height-adjustable ground foot for experimental equipment. The ground foot comprises a base, wherein an outer thread structure is arranged outside the lower end of the base, a thread at the lower part of the base is fixedly connected with a ground foot seat, a mounting hole is formed in the upper end of the base, a transmission screw rod is connected in the mounting hole through a bearing, the upper end of the screw rod is connected with a pushing block and a ground foot mounting plate sequentially from bottom to top, the pushing block is movably clamped with the screw rod, symmetrical ball grooves are machined in the upper end surface of the pushing block and the lower end surface of the ground foot mounting plate respectively, balls are arranged in the two ball grooves, the lower end of the base is fixedly connected with a motor, and one end of a motor shaft of the motor is fixedly connected with the lower end of the screw rod. The ground foot has the benefits as follows: by means of the ground foot, the experimental equipment can be lifted and lowered and is suitable for people with different heights, and meanwhile, the equipment is controlled by infrared remote control to be lifted and lowered, so that use by students is greatly facilitated, and the experimental efficiency is improved.

Description

A kind of experimental facilities adjustment height lower margin

Technical field

The utility model relates to experimental facilities technical field, relates in particular to a kind of experimental facilities adjustment height lower margin.

Background technology

At present, under prior art for experiment porch device, the laboratory table of testing as done etc., it cannot realize oscilaltion, causes it not to be suitable for the different experiments that require, and is not also suitable for the student of different heights.

Utility model content

For the deficiencies in the prior art, the utility model provides a kind of experimental facilities adjustment height lower margin.

To achieve these goals, the technical scheme in the invention for solving the technical problem is:

A kind of experimental facilities adjustment height lower margin, comprise pedestal, outside, pedestal lower end is provided with external thread structure, pedestal lower thread is connected with ground runners, inside, upper end at pedestal is provided with an installing hole, in installing hole, be connected with drive lead screw by bearing, the upper end of screw mandrel is connected with ejection piece and lower margin installing plate from the bottom to top in turn, described ejection piece and screw mandrel activity clamping, be processed with respectively symmetrical ball grooves in the upper surface of ejection piece and the lower surface of lower margin installing plate, in two ball grooves, be provided with ball, be connected with motor in pedestal lower end, the motor shaft end of described motor and the bottom of screw mandrel are affixed.

As preferably, be processed with an annular groove in the lower end of described ground runners, in annular groove, be provided with Rubber shock-absorbing pad.

As preferably, the degree of depth sum of two described ball grooves is less than the diameter of ball.

As preferably, on described ground runners, infrared ray starting switch is installed, described infrared ray starting switch is electrically connected with motor, and infrared ray starting switch is electrically connected with power supply, and described infrared ray starting switch is connected to remote control switch by radio company.

The beneficial effects of the utility model: this utility model can make experimental facilities realize elevating function, make experimental facilities be applicable to the crowd of different heights, adopt the lifting of infra-red remote control control appliance simultaneously, facilitate widely student's use.Improve conventional efficient.

Brief description of the drawings

Fig. 1 is cutaway view of the present utility model.

Detailed description of the invention

A kind of experimental facilities adjustment height lower margin as shown in Figure 1, comprise pedestal 1, it should be noted that, pedestal 1 outside, lower end is provided with external thread structure, pedestal 1 lower thread is connected with ground runners 2, carry out the height of adjusting base by screw thread, be provided with an installing hole 3 in the inside, upper end of pedestal 1, in installing hole 3, be connected with drive lead screw 5 by bearing 4, the upper end of screw mandrel 5 is connected with ejection piece 6 and lower margin installing plate 7 from the bottom to top in turn, described ejection piece 6 is also passable with screw mandrel 5 activity clampings or other connected mode, be processed with respectively symmetrical ball grooves 8 in the upper surface of ejection piece 6 and the lower surface of lower margin installing plate 7, in two ball grooves 8, be provided with ball 9, be connected with motor 10 in pedestal 1 lower end, the motor shaft end of described motor 10 is affixed with the bottom of screw mandrel 5 or be flexibly connected.Realize and moving up and down by the motion of ball and screw rod, be similar to the principle of track.

Further it should be noted that and be processed with an annular groove 21 in the lower end of described ground runners 2, certainly, is not that cannelure also can be realized, and is provided with Rubber shock-absorbing pad 11 in annular groove 21, reduces like this vibrations, increases buffering.The degree of depth sum of two described ball grooves 8 is less than the diameter of ball 9, better effects if like this.

Further it should be noted that on described ground runners infrared ray starting switch is installed, described infrared ray starting switch is electrically connected with motor, infrared ray starting switch is electrically connected with power supply, described infrared ray starting switch is connected to remote control switch by radio company, regulates the lifting of ground runners by ultrared control.

Claims
