Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses a pitch needle penetration tester, as shown in fig. 1, including workstation 1, be provided with the constant temperature basin on workstation 1, the pitch sample is placed in the constant temperature basin, is provided with support 2 on the workstation 1, is provided with fixed disk 3 on the support 2, and fixed disk 3 is located constant temperature basin top, is provided with standard needle 4 on the fixed disk 3, and standard needle 4 includes syringe needle 41 and needle point 42.

Combine fig. 1 and fig. 2, because need do the parallel experiment of multiunit to same sample at every turn, for saving the time of changing standard needle 4 midway, be provided with many standard needles 4 on fixed disk 3, the last rotation of support 2 is connected with pivot 15, fixed disk 3 and the coaxial fixed connection of pivot 15 are provided with on workstation 1 and are used for ordering about pivot 15 pivoted driving piece. The rotating shaft 15 is driven to rotate through the driving piece so as to drive the fixed disk 3 to rotate, so that the new standard needle 4 on the fixed disk 3 can be adjusted to a position corresponding to an asphalt sample to be tested, and the testing efficiency is further improved.

With reference to fig. 1 and 2, in order to facilitate the position adjustment of the standard needle 4 by the tester, the driving member includes a supporting plate 16 disposed on the worktable 1, a worm wheel 17 is sleeved on the rotating shaft 15, a worm 18 meshed with the worm wheel 17 is disposed on the supporting plate 16 in a penetrating and rotating manner, and the central axis of the rotating shaft 15 is perpendicular to the central axis of the worm 18.

When the fixed disc 3 needs to be rotated, a tester rotates the handle 19 to drive the worm 18 to rotate, the worm 18 drives the worm wheel 17 to rotate, and therefore the fixed disc 3 is driven to rotate, and the standard needle 4 is adjusted to a proper position to be used.

Combine fig. 1 and fig. 3, offer the through-hole 5 that is used for supplying standard needle 4 to pass on the fixed disk 3, on the 5 inner walls of through-hole and along the 5 axis direction sliding connection of perpendicular to through-hole there is butt piece 6, through-hole 5 inner walls are offered and are used for supplying the gliding spout 11 of butt piece 6, butt piece 6 is located the 5 inner sections of through-hole and is provided with inclined plane 7, inclined plane 7 orientation is close to the direction downward sloping setting of workstation 1, it slides to keeping away from through-hole 5 center to promote inclined plane 7 along through-hole 5 axial, be provided with cardboard 10 along syringe needle 41 lateral wall, draw-in groove 8 has been seted up to cardboard 10 circumference, be provided with between butt piece 6 and the fixed disk 3 and be used for ordering about the elastic component that butt. The elastic piece is set to be a spring 9, one end of the spring 9 is connected to the bottom wall of the sliding groove 11, and the other end of the spring 9 is connected with the abutting block 6.

When standard needle 4 is installed to needs, down pass through-hole 5 from last with standard needle 4, because needle point 42 is less than syringe needle 41, when syringe needle 41 moves to the inclined plane 7 contact with butt piece 6, butt piece 6 slides towards keeping away from through-hole 5 center under the effect of external force, when draw-in groove 8 on syringe needle 41 moved to the position that corresponds with butt piece 6, butt piece 6 receives the elasticity joint of spring 9 in draw-in groove 8, prevent that standard needle 4 from dropping downwards, standard needle 4 joint is on fixed disk 3 this moment.

With reference to fig. 1 and 3, in order to facilitate the card board 10 to push the inclined plane 7 to drive the abutting block 6 to move under the driving of the needle 41, a surface of the card board 10 close to the needle point 42 is an inclined plane 12, the inclined plane 12 is inclined upward toward a direction away from the workbench 1, and the inclined plane 12 is arranged to increase a contact area between the card board 10 and the inclined plane 7, so as to push the inclined plane 7 to move when the needle 41 moves downward.

Combine fig. 1 and 3, for avoiding the phenomenon that the laboratory technician carelessly exert oneself too greatly and harm syringe needle 41 when pulling standard needle 4 downwards, set up the recess 13 with spout 11 intercommunication on the face that workstation 1 was kept away from to fixed disk 3, the both ends of recess 13 are sealed and are set up, butt piece 6 is located the tip of spout 11 and is provided with dials strip 14, dial strip 14 and pass the setting of recess 13, it breaks away from with draw-in groove 8 to dial strip 14 when being located the one end that through-hole 5 was kept away from to recess 13. When the standard needle 4 needs to be taken down from the fixed disk 3, a tester adjusts the shifting strip 14 to drive the abutting block 6 to be separated from the clamping groove 8, so that the standard needle 4 can be taken down from the upper side of the fixed disk 3, and the test device is simple and convenient.

The implementation principle of the embodiment is as follows:

when new standard needle 4 of needs installation, down pass through-hole 5 with standard needle 4 from last, because needle point 42 is less than syringe needle 41, inclined plane 12 of cardboard 10 on syringe needle 41 moves to when 7 contacts with the inclined plane of butt piece 6, butt piece 6 slides towards keeping away from through-hole 5 center under the effect of external force, draw-in groove 8 when moving to the position that corresponds with butt piece 6 on cardboard 10, butt piece 6 receives spring 9's elasticity joint in draw-in groove 8, prevent that standard needle 4 from dropping downwards, standard needle 4 joint is on fixed disk 3 this moment. When the standard needle 4 needs to be taken down from the fixed disk 3, a tester adjusts the shifting strip 14 to drive the abutting block 6 to be separated from the clamping groove 8, so that the standard needle 4 can be taken down from the upper side of the fixed disk 3, and the test device is simple and convenient.

When the rest standard needles 4 on the fixed disc 3 are required to be tested, a tester rotates the handle 19 to drive the worm 18 to rotate, the worm 18 drives the turbine 17 to rotate, and therefore the fixed disc 3 is driven to rotate, and the new standard needles 4 are adjusted to be suitable for use.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
