Specific embodiment

For the ease of the understanding of those skilled in the art, the utility model is made below with reference to embodiment and attached drawing further Explanation, the content that embodiment refers to not is restriction to the utility model.The utility model is carried out below in conjunction with attached drawing Detailed description.

As depicted in figs. 1 and 2, a kind of low oil level grease sensor provided by the utility model, including floating ball 1, spring 2 with And the main body 3 for testing liquid level, the main body 3 include interconnecting piece 31 and test department 32, the insertion of the test department 32 simultaneously projection The floating ball 1 out, the interconnecting piece 31 are used for connecting test instrument；The test department 32 stretches out one end setting of the floating ball 1 Have the split washer 4 risen for floating ball 1 described in block, when spring reset, the floating ball and split washer against；The bullet Spring 2 is surrounded on the test department 32, and the both ends of the spring 2 contradict the floating ball 1 and the test department 32 respectively.Specifically, The bottom of interconnecting piece is connected with the conducting wire 6 for external detection device.

When the utility model is used, be mounted to the bottom of tank body: when the intracorporal grease of tank is in high liquid level, pressure Oil clot increases under grease buoyancy, and spring 2 jacks up floating ball, and test department 32 keeps closing because of the effect not being under pressure Conjunction is connect with the signal of test equipment；When the intracorporal liquid level of tank reduces, pressure oil block can decline as liquid level reduces, until with Floating ball 1 contacts and pushes floating ball 1, and floating ball 1 applies pressure to test department 32 by spring 2；When liquid level is reduced to lower threshold value, pressure Oil clot reaches preset threshold value by the pressure that floating ball 1 is applied to test department 32, so that test department 32 and test equipment Signal connection disconnects, to remind grease in user's oil tank insufficient, to allow user that can add grease toward oil tank in time.

In addition to this, when the utility model is applied in the biggish grease of viscosity, floating ball 1 is possible to can be because being sticked by grease It firmly can not reliably float, at this time due to there is the presence of spring 2, utilize the reset force of spring 2, it is ensured that floating ball 1 can be by Jack up, thus ensure that the utility model at this moment viscosity big grease when, can also reliably, accurately feed back whether grease fills The signal of foot.

As shown in Figure 1, in the present embodiment, the floating ball 1 is provided with the liquid level stroke pad for being used to support and balancing floating ball 1 Piece 5, the liquid level stroke gasket 5 surround one end described in test department 32.Liquid level stroke gasket 5 is used to support the intracorporal pressure oil of tank Block guarantees that pressure oil block with vertical direction applies pressure to the utility model, enables in 32 accurate feedback oil tank of test department Whether grease is insufficient.

Preferably, as shown in figure 3, the bottom of the liquid level stroke gasket 5, which is provided with, contradicts plate 51, the conflict plate 51 It is contradicted with the floating ball 1, the test department 32 and the split washer 4 stretch out the conflict plate 51.I.e. in the present embodiment Liquid level stroke gasket 5 and floating ball 1 be two components separated, can liquid level stroke gasket 5 break down when, only replace liquid Position stroke gasket 5, reduces the cost of maintenance.

As illustrated in figure 1 or 4, in the present embodiment, the interconnecting piece 31 is provided with the screw thread for connecting test equipment 311, it allows the utility model to be to be attached by way of being spirally connected with tester, so that connection is more secured, is also convenient for this The dismounting of utility model.

Preferably, as shown in figure 4, the side of the test department 32 is provided with for preventing screw thread 311 from screwing togather too deep limit Position part 322, the spring 2 are contradicted with the locating part 322.When locating part 322 and tester or tank bottom contradict, that is, demonstrate,prove Be illustrated and interconnecting piece 31 and be spirally connected completely just with tester, thus avoid because interconnecting piece 31 screw togather it is too deep due to make screw thread 311 Deformation；Meanwhile locating part 322 increases the area contacted with spring 2, so that the feedback of pressure is more stable.

Preferably, as shown in figure 4, the test department 32 is provided with the anti-shake part 323 for preventing the spring 2 from shaking, The spring 2 is surrounded on the anti-shake part 323, with to avoid image side side deformation due to unbalance stress of spring 2, to ensure that bullet The reliability of spring 2.

As shown in Fig. 2, in the present embodiment, the split washer 4 is circlip, the test department 32 stretches out described floating One end of ball 1 is provided with the card slot 321 for blocking the split washer 4.Circlip is a kind of common component, can be stablized Block floating ball 1 in ground.

Specifically, the side of the liquid level stroke gasket 5 offers recessing groove 52, it is used for when assembling the utility model, For stepping down to split washer 4, consequently facilitating assembling opening retaining ring 4.

The above is only the utility model preferred embodiment, is not made in any form to the utility model Limitation, although the utility model is disclosed as above with preferred embodiment, is not intended to limit the utility model, any to be familiar with sheet Technical professional is not departing within the scope of technical solutions of the utility model, makes when using the technology contents of the disclosure above A little change or the equivalent embodiment for being modified to equivalent variations, but it is all without departing from the content of the technical scheme of the utility model, foundation The utility model technology refers to any simple modification, equivalent change and modification to the above embodiments, belongs to practical In the range of new technique scheme.
