Abstract
Description
Technical Field
[0001] This utility model relates to the field of friability tester technology, and in particular to a speed control device for a friability tester. Background Technology
[0002] A friability tester is an instrument used to test the friability of objects. It typically consists of a main unit, a test chamber, a base, a support column, a controller, and a mounting structure. The test chamber is mounted on the main unit, the support column on the base, and the controller and mounting structure are located on the support column and control box, respectively. Friability testers are mainly used to test the friability of pharmaceutical tablets, experimental samples, etc. By simulating certain conditions (such as rotation and impact), the tester observes the breakage of the sample after being subjected to force, thereby assessing its friability.
[0003] In existing fragility meters, speed control is typically achieved using the meter's controller. However, the controller, once installed in its housing, exposes a control panel for speed control. This control panel is easily altered by accident after the speed value is entered, thus affecting the speed control operation of the fragility meter. Therefore, we propose a speed control device for fragility meters. Utility Model Content
[0004] The main objective of this invention is to provide a speed control device for a fragility meter. A protective screen mechanism is installed on the fragility meter body. This protective screen mechanism can be assembled on the surface of the fragility meter body to protect the controller. When the speed control value of the fragility meter body is input to the controller, the protective screen mechanism can protect the controller surface of the fragility meter body, thereby preventing accidental operation of the fragility meter body. Furthermore, rubber pads are provided on the surface of the fragility meter body. When the acrylic protective plate and the vertical plate of the protective screen mechanism are accidentally pressed, the rubber pads can buffer the pressure of the acrylic protective plate and the vertical plate on the controller, effectively preventing accidental activation of the controller used for speed control of the fragility meter body. This effectively solves the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A speed control device for a friability tester includes a friability tester body and a controller. The controller is mounted on the inclined surface of the housing of the friability tester body. The device also includes a screen protection mechanism, which comprises a mounting plate, studs, a guide rod, a sleeve, a connecting plate, an acrylic protective plate, rubber strips, a vertical plate, and a hook plate. The mounting plate is symmetrically welded to the top of the friability tester body above the controller. A threaded hole for inserting a stud is provided through the surface of the mounting plate. The studs are symmetrically welded to both ends of the guide rod. A sleeve is fitted onto the outside of the guide rod. One side of the sleeve is connected to an acrylic protective plate covering the surface of the controller via a connecting plate. A vertical plate is attached to the bottom of the acrylic protective plate with a rubber strip. Hook plates are arranged and fixed at the bottom of the vertical plate. A groove for engaging the hook plates is provided on the surface of the friability tester body below the vertical plate.
[0007] Furthermore, the surface of the friability meter body outside the controller is covered with rubber pads in a rectangular distribution, and acrylic protective plates and vertical plates are pressed onto the surface of the rubber pads.
[0008] By adopting the above technical solution, the surface of the friability meter body outside the controller is buffered by rubber pads in contact with the acrylic protective plate and the vertical plate.
[0009] Furthermore, a notch is recessed on the outer end face of the stud away from the guide rod;
[0010] By adopting the above technical solution, a flathead screwdriver can be inserted into the slot at the stud, thereby unscrewing the stud out of the screw hole.
[0011] Furthermore, the diameter of the sleeve cavity is the same as the diameter of the rod body;
[0012] By adopting the above technical solution, the sleeve can be rotated around the smooth rod.
[0013] Furthermore, three sets of hook plates are arranged and fixed on the lower surface of the vertical plate, and the cylindrical hook head of the hook plate is inserted into the fixed groove of the friability tester body.
[0014] By adopting the above technical solution, the vertical plate is installed by using three sets of bent hook plates in conjunction with cylindrical hook heads to be inserted into the fixed groove.
[0015] Furthermore, the bending connecting plate is integrally formed in three sets between the sleeve and the acrylic protective plate;
[0016] By adopting the above technical solution, the sleeve and the acrylic protective plate are firmly connected by three sets of bent connecting plates.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model provides a protective screen mechanism on the body of the friability meter. The protective screen mechanism can be assembled on the surface of the friability meter body to protect the controller. When the speed control value of the friability meter body is input into the controller, the protective screen mechanism can protect the controller surface of the friability meter body, thereby preventing the friability meter body from being accidentally operated.
[0019] Furthermore, the surface of the friability meter is equipped with rubber pads. When the acrylic guard plate and the vertical plate of the protective screen mechanism are accidentally pressed, the rubber pads can buffer the pressure of the acrylic guard plate and the vertical plate on the controller, effectively preventing the controller used for controlling the speed of the friability meter from being accidentally activated.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1-2 As shown, a speed control device for a friability tester includes a friability tester body 1 and a controller 2. The controller 2 is mounted on the inclined surface of the housing of the friability tester body 1. The device also includes a screen protection mechanism 3, which comprises a mounting plate 4, a stud 6, a guide rod 7, a sleeve 9, a connecting plate 10, an acrylic protective plate 11, a rubber strip 12, a vertical plate 13, and a hook plate 14. The mounting plates 4 are symmetrically welded to the top of the friability tester body 1 above the controller 2, and the surface of the mounting plates 4 has through-cut openings. The screw hole 5 is used to screw in the stud 6. The stud 6 is symmetrically welded to both ends of the rod body of the smooth rod 7. The rod body of the smooth rod 7 is fitted with a sleeve 9. One side of the sleeve 9 is connected to an acrylic protective plate 11 covering the surface of the controller 2 through a bending connecting plate 10. The bottom of the acrylic protective plate 11 is glued with a rubber strip 12 to a vertical plate 13. The bottom of the vertical plate 13 is fixed with a hook plate 14. The surface of the brittleness meter body 1 below the vertical plate 13 is provided with a fixed groove 15 for engaging the hook plate 14.
[0025] Among them, the surface of the friability meter body 1 outside the controller 2 is covered with rubber pads 16 in a rectangular distribution, and the surface of the rubber pads 16 is pressed with an acrylic guard plate 11 and a vertical plate 13.
[0026] By adopting the above technical solution, the surface of the friability meter body 1 outside the controller 2 is buffered by rubber pads 16 in contact with the acrylic guard plate 11 and the vertical plate 13.
[0027] Among them, the outer end face of the stud 6 away from the light rod 7 has a groove 8;
[0028] By adopting the above technical solution, a flathead screwdriver can be inserted into the slot 8 at the stud 6, thereby unscrewing the stud 6 out of the screw hole 5.
[0029] The diameter of the sleeve 9 is the same as the diameter of the rod body of the smooth rod 7;
[0030] By adopting the above technical solution, the sleeve 9 can be fitted over the smooth rod 7 and rotated.
[0031] Among them, three sets of hook plates 14 are arranged and fixed on the lower plate surface of the vertical plate 13, and the cylindrical hook head of the hook plate 14 is inserted into the fixed groove 15 of the friability meter body 1.
[0032] By adopting the above technical solution, the vertical plate 13 is fitted into the fixed groove 15 by three sets of bent hook plates 14 in conjunction with the cylindrical hook head.
[0033] Among them, the bending connecting plate 10 is integrally formed in three sets between the sleeve 9 and the acrylic protective plate 11;
[0034] By adopting the above technical solution, the sleeve 9 and the acrylic protective plate 11 are firmly connected by three sets of bending connecting plates 10.
[0035] It should be noted that this utility model is a speed control device for a friability meter. A protective screen mechanism 3 is provided on the friability meter body 1. After the speed is controlled by the controller 2 for speed control mounted on the surface of the friability meter body 1, the protective screen mechanism 3 can fix the mounting plate 4 on the top of the friability meter body 1. After the side rings at both ends of the friability meter body 1 are removed, the sleeve 9 can be inserted between the mounting plates 4. Then, the stud 6 at one end of the guide rod 7 can be screwed into the screw hole 5 of one side of the mounting plate 4. Then, this set of studs 6 can be screwed into the screw hole 5 of the other side of the mounting plate 4, so that the latter set of studs 6 is screwed into the screw hole 5 of the mounting plate 4. The guide rod 7 can be inserted into the sleeve 9 to provide rotational support. Then, the surface of the friability meter body 1 outside the controller 2 is bonded. When the speed control value of the friability meter body 1 is input into the control panel of the controller 2, the acrylic protective plate 11 flips at the light rod 7 through the sleeve 9 connected by the bending connecting plate 10, so that the acrylic protective plate 11 and the vertical plate 13 cover the surface of the rubber pad 16 on the surface of the friability meter body 1. Then, the hook plate 14 at the bottom of the vertical plate 13 can be inserted into the fixed groove 15 of the friability meter body 1 for positioning. Under the protection of the acrylic protective plate 11, the controller 2 used for speed control of the friability meter is not easily operated by external interference. After the hook plate 14 is lifted up away from the fixed groove 15, the vertical plate 13 and the acrylic protective plate 11 can be flipped up to cover the top of the friability meter body 1, making it convenient to operate the controller 2 to control the speed of the friability meter body 1.
