Abstract
The invention relates to a cam lifting device for an examination bed. The cam lifting device comprises a universal wheel, wherein the wheel rod of the universal wheel is movably arranged inside a shell; a gland is fixed on the top part of the wheel rod; a spring is sleeved on the wheel rod; the upper end of the spring is contacted with the gland; the lower end of the spring is contacted with the shell; a shaft is movably arranged in the shell; the shaft is fixed with a cam; the cam surface of the cam is adhered to the gland; and one end of the shaft extends out of the shell and is connected with a pedal lever. The cam lifting device is applicable to the examination bed, makes the examination bed realize the moving and fixing functions, and prevents the examination bed from moving due to abrasion when the examination bed needs fixing.
Description
Technical field
The present invention relates to the technical field of medical apparatus and instruments, refer more particularly to a kind of Cam lifting device for examination bed.
Background technology
Examination bed requires again to be fixed on certain position when examining because its special field of employment must be able to be moved when seeing and treating patients patient.The most examination bed is all used with the universal wheel of service brake and is realized this function.But when the service brake of universal wheel was worn, examination bed can occur mobile when examining, and brought potential safety hazard for examination person.
Summary of the invention
Technical problem to be solved by this invention is: a kind of Cam lifting device for examination bed is provided, can makes examination bed realize the function can move and can fix, and can not make because of wearing and tearing examination bed occur movement fixedly the time at needs.
For addressing the above problem, the technical solution used in the present invention is: be used for the Cam lifting device of examination bed, comprise universal wheel, the wheel bar of universal wheel is movably arranged on the inside of housing, the top of wheel bar is fixed with gland, be set with spring on the wheel bar, the upper end of spring contacts with gland, and the lower end of spring contacts with housing, be movably set with axle in the described housing, be fixed with cam on the axle, wheel face and the gland of cam fit, and an end of axle stretches out housing and is connected with treadle.
Be fixed with axle sleeve in the described housing, the wheel bar of described universal wheel is movably arranged in the axle sleeve, and the lower end of described spring contacts with the upper end of axle sleeve.
Be fixed with two cams on the described axle, two cams are symmetricly set on the both sides at gland center, the wheel face of two cams fits with gland respectively, and the axle between two cams is provided with short positioning sleeve, and the axle between two cams and housing is respectively arranged with long positioning sleeve.
Be provided with spill spin block on the described axle that stretches out housing, an end of described treadle is connected with spill spin block.
The invention has the beneficial effects as follows: the above-mentioned Cam lifting device that is used for examination bed is simple in structure, easy to operate, long service life.After above-mentioned Cam lifting device is installed in the bed panel bottom of examination bed, when examination bed need to move, universal wheel is descended, this moment, universal wheel contacted with ground, four cabinet bases of examination bed are in vacant state, and examination bed can be realized mobile function by universal wheel; When examination bed fixedly the time, universal wheel is retracted, this moment, universal wheel was unsettled, examination bed fixes on the ground by four cabinet bases, when examining, can not occur mobile, thereby bring potential safety hazard can not for examination person.
Description of drawings
Fig. 1 is the plan structure schematic diagram of the Cam lifting device for examination bed of the present invention;
Fig. 2 is the sectional structure schematic diagram of A-A direction among Fig. 1;
Fig. 3 is the structural representation of the another kind of state of Fig. 2;
Among the figure: 1, universal wheel, 2, housing, 3, axle sleeve, 4, the wheel bar, 5, gland, 6, spring, 7, axle, 8, cam, 9, short positioning sleeve, 10, long positioning sleeve, 11, spill spin block, 12, treadle.
The specific embodiment
Below by specific embodiment the Cam lifting device that the present invention is used for examination bed is described in further detail.
Such as Fig. 1, shown in Figure 2, make and use for convenient, in the present embodiment two Cam lifting devices that are used for examination bed are made into integrative-structure, its structure comprises two universal wheels 1 and two housings 2, be fixed with respectively axle sleeve 3 in two housings 2, the wheel bar 4 of two universal wheels 1 is movably arranged on respectively in the axle sleeve 3, each top of taking turns bar 4 is fixed with respectively gland 5, each is taken turns and is respectively installed with spring 6 on the bar 4, the upper end of spring 6 contacts with gland 5, the lower end of spring 6 contacts with the upper end of axle sleeve 3, an axle 7 penetrates and is arranged in two housings 2, be fixed with four cams 8 on the axle 7, four cams 8 are arranged on the top of each universal wheel 1 in twos, two cams 8 on each universal wheel 1 top are symmetricly set on the both sides at gland 5 centers, and the wheel face of each cam 8 all fits with gland 5, axle 7 between two cams 8 is provided with short positioning sleeve 9, axle 7 between two cams 8 and housing 2 is respectively arranged with long positioning sleeve 10, short positioning sleeve 9 and long positioning sleeve 10 can make axle 7 displacement can not occur in housing 2, two housings 2 are stretched out respectively at the two ends of axle 7, be respectively arranged with spill spin block 11 at the axle 7 that stretches out housing 2, each spill spin block 11 is connected with an end of treadle 12 respectively.
Operation principle of the present invention is: during use, the top of the housing of the above-mentioned Cam lifting device that is used for examination bed is fixed on the bed panel bottom of examination bed, and examination bed need not the again universal wheel of mounting strap service brake, only need to use common cabinet base, four Cam lifting devices are corresponding with four cabinet bases.As shown in Figure 2, the universal wheel 1 that is used for the Cam lifting device of examination bed is in retracted mode, this moment, minor axis face and the gland 5 of cam 8 fitted, elastic force by spring 6 up promotes universal wheel 1, so that universal wheel 1 is in vacant state, this moment, examination bed can fix on the ground by four cabinet bases, can not occur moving when examining, thereby bring potential safety hazard can not for examination person; As shown in Figure 3, the universal wheel 1 that is used for the Cam lifting device of examination bed is in the state of stretching out, turn treadle 12 under state shown in Figure 2, then be with moving axis 7 to rotate, thereby band moving cam 8 rotates, major diameter face and the gland 5 of cam 8 fit, thereby universal wheel 1 is pressed down, this moment, spring 6 was in contraction state, contact with ground after universal wheel 1 stretches out, so that four cabinet bases of examination bed are in vacant state, this moment, examination bed can be realized mobile function by universal wheel 1, the treadle 12 that only need circle round when needing fixedly just can be got back to state shown in Figure 2.
