Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one：A kind of cement mortar plain bumper, as shown in figure 1, including base 1, preceding bearing 2, rear support 3, rocking arm
4, the one end of base 1 is fixedly connected with preceding bearing 2, and the other end is fixedly connected with rear support 3, and Rocker arm 4 one end is hinged with preceding bearing 2,
The other end is fixedly connected with table top 41, and cam 31 is rotatably connected on rear support 3, and the lower rotation of table top 41 is connected with and cam
31 driven pulleys 411 coordinated, preceding bearing 2 rotates the fulcrum for providing power for Rocker arm 4, and cam 31 is eccentric wheel, and cam 31 is turning
With the conflict of driven pulley 411 when dynamic, while the phenomenon of shock occurs with cam 31 for driven pulley 411, swing table surface is reached
The experiment effect of cement mortar on 41.
As shown in Figures 3 and 4, cement mortar plain bumper can be repeatedly used when experimental work is carried out, and used
The phenomenon of abrasion occurs with the preceding hinged end of bearing 2 for meeting Rocker arm 4 after a period of time, causes the Rocker arm 4 during experiment to occur
Rocking in horizontal direction, so as to have impact on the process that experiment is carried out.In order to reduce the movement of Rocker arm 4 horizontal direction generation to reality
The influence tested, the gag lever post 5 provided with the horizontal direction movement of limitation Rocker arm 4 on base 1, gag lever post 5 is set respectively provided with two
Put in the both sides of Rocker arm 4, gag lever post 5 can effectively limit the position movement of Rocker arm 4 in the horizontal direction, improve cement gel
The stability of sand plain bumper in an experiment；Shaken simultaneously in order to reduce generation frictional influence cement mortar between gag lever post 5 and Rocker arm 4
The normal of real platform is used, the presence gap 6 between gag lever post 5 and Rocker arm 4, and gap 6 avoids producing between gag lever post 5 and Rocker arm 4
Frictional force, it is ensured that the stability of cement mortar plain bumper in an experiment.
As illustrated in fig. 1 and 2, in order to further improve the stability of cement mortar plain bumper in an experiment, on base 1
Provided with stop collar 11, stop collar 11 is arranged on the center between two gag lever posts 5, at the same on Rocker arm 4 be provided with it is spacing
The limited block 42 of 11 grafting cooperation is covered, the grafting during experiment of limited block 42 and stop collar 11 coordinates, further reduced
Rocker arm 4 produces situation about rocking after a number of uses.Stop collar 11 is hollow cylinder, and limited block 42 is column, in limited block
42 are provided with the hemisphere 421 coordinated with limited post grafting away from Rocker arm 4 end；When the feelings rocked occurs during use in Rocker arm 4
During condition, limited block 42 and stop collar 11 the meeting existence position deviation during grafting, hemisphere 421 is arc surface in limited block 42
Guiding can be played a part of with during the grafting of stop collar 11, while being provided with inwall of the stop collar 11 away from the end of base 1
Circular arc chamfering 1, circular arc chamfering 1 further adds the splicing stability of limited block 42 and stop collar 11, reduces
There is the phenomenon of interim card during limited post and the grafting of stop collar 11, so as to improve cement mortar plain bumper in an experiment steady
It is qualitative.
Embodiment two：A kind of cement mortar plain bumper, is with the difference of embodiment one, as it can be seen in figures 5 and 6, will be convex
The width of wheel 31 is more than the width of driven pulley 411；The contact area of driven pulley 411 and cam 31 is improved, is reduced in experiment
During because Rocker arm 4 being rocked, there is driven pulley 411 and the situation that dislocation is got stuck occur in cam 31, it is ensured that cement mortar
Stability of the plain bumper during use.The phenomenon rocked to reduce Rocker arm 4 to occur during use, in cam
31 are provided with the groove 311 placed for driven pulley 411, while the notch in groove 311 is provided with circular arc chamfering 2 3111；Driven pulley
During 411 contact with cam 31, the groove 311 on cam 31 has further restriction effect to the position of driven pulley 411,
The phenomenon that Rocker arm 4 is moved in the horizontal direction is reduced, circular arc chamfering 2 3111 is conducive to driven pulley 411 to enter groove
In 311, reduce because Rocker arm 4 rocks the situation for causing driven pulley 411 to cannot be introduced into groove 311.
Because cement mortar plain bumper is during use, cam 31 and driven pulley 411 can be produced when hitting
The phenomenon of abrasion, in order to ensure the stability of cement mortar plain bumper work, reduces the abrasion of driven pulley 411 and cam 31, institute
To be arranged with rub resistance set 4111 on driven pulley 411, friction sleeve is conducive to reducing the abrasion of driven pulley 411, so as to improve
Cement mortar plain bumper is in the stability during, while also improve the service life of cement mortar plain bumper.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
