These devices can be automatically started according to preset time intervals or working conditions, extrude lubricating grease from a storage container, and transport it to the parts that need lubrication through a nozzle or pipeline; in the prior art, the operation of replacing the nozzle is cumbersome, and the threaded installation often requires multiple turns to unscrew, and it is easy to cause damage to the greaser body during the replacement process after long-term use; in addition, the fixed nozzle structure is difficult to adapt to the lubrication requirements in different working environments, restricting the use range of the greaser.

[0003] Therefore, there is a need for a nozzle structure that is convenient to replace and does not damage the intelligent greaser during the replacement process. Summary of the Utility Model

The replacement nozzle includes a magnetic suction bottom cylinder integrally connected to the lower nozzle port.

[0007] The magnetic suction top cylinder includes a positioning wall, a slot wall a, and a grease wall a connected to the top from the outside to the inside. Three magnetic rings a are fixed in the groove between the positioning wall and the slot wall a, and a sealing cover a is fixed to the bottom of the magnetic ring a. The circular groove between the slot wall a and the grease wall a is evenly divided into eight magnetic block slots a, and magnetic blocks a are built in each of them.

Three magnetic rings b are fixed in the groove between the slot wall b and the outer wall, and a sealing cover d is fixed to the top of the magnetic ring b. Four clamping blocks are fixed to the outside of the outer wall.

[0009] Further, the positions and sizes of the magnetic rings a and b correspond to each other; the magnetic poles facing downward of the outermost and innermost of the three magnetic rings a are the same and attract the outermost and innermost magnetic rings b, and the magnetic pole facing downward of the middle magnetic ring a is opposite to that of the two sides and attracts the magnetic ring b at the middle position below.

[0010] Further, the magnetic poles facing downward of adjacent magnetic blocks a are opposite, and the magnetic poles facing upward of adjacent magnetic blocks b are opposite.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0034] Such as Figures 1 to 9As shown in the figure, the utility model includes a replacement nozzle 2 magnetically attracted and clamped with the fixed end cap 1 on the upper layer. The fixed end cap 1 includes a magnetic attraction top cylinder 102 integrally connected with the upper threaded ring 101. The replacement nozzle 2 includes a magnetic attraction bottom cylinder 202 integrally connected with the lower nozzle port 201. The function of the replacement nozzle 2 is to quickly disassemble and replace different models or damaged nozzle ports 201.

[0035] The magnetic attraction top cylinder 102 includes a positioning wall 3, a clamping groove wall a4, and a grease wall a8 connected to the top from the outside to the inside. Three magnetic rings a501 are fixed in the groove between the positioning wall 3 and the clamping groove wall a4, and a sealing cover a5 is fixed at the bottom of the magnetic ring a501. The fixing method is conventional bonding. The circular groove between the clamping groove wall a4 and the grease wall a8 is evenly divided into eight magnetic block grooves a602, and magnetic blocks a601 are built in each of them. A sealing cover b6 is fixed at the bottom of the magnetic block groove a602 and the magnetic block a601. A downward-facing fixed clamping groove 7 is arranged on the outside of the positioning wall 3 to ensure the tightening of the magnetic attraction bottom cylinder 202.

[0036] The magnetic attraction bottom cylinder 202 includes a grease wall b9, a clamping groove wall b10, and an outer wall 11 connected to the bottom from the inside to the outside. The circular groove between the grease wall b9 and the clamping groove wall b10 is evenly divided into eight magnetic block grooves b1202, and magnetic blocks b1201 are built in each of them. A sealing cover c12 is fixed at the top of the magnetic block groove b1202 and the magnetic block a1201. Three magnetic rings b1301 are fixed in the groove between the clamping groove wall b10 and the outer wall 11, and a sealing cover d13 is fixed at the top of the magnetic ring b1301. Four clamping blocks 1101 are fixed on the outside of the outer wall 11.

[0037] The positions and sizes of the magnetic rings a501 and the magnetic rings b1201 correspond to each other. The magnetic poles facing down of the outermost and innermost of the three magnetic rings a501 are the same and attract the outermost and innermost magnetic rings b1301. The magnetic pole facing down of the middle magnetic ring a501 is opposite to that of the two sides and attracts the middle magnetic ring b1301 below.

[0038] The magnetic poles facing down of adjacent magnetic blocks a601 are opposite to each other, and the magnetic poles facing up of adjacent magnetic blocks b1201 are opposite to each other.

[0039] Four clamping groove blocks 701 that can be adapted to the clamping blocks 1101 are installed in the fixed clamping groove 7 in a row. Each clamping groove block 701 corresponds to a magnetic block a601, and each clamping block 1101 corresponds to a magnetic block b1201.

[0040] The magnetic pole facing down of the magnetic block a601 corresponding to the clamping groove block 701 is the same as the magnetic pole facing up of the magnetic block b1201 corresponding to the clamping block 1101. The arc angles of the clamping groove blocks 701 and the clamping blocks 1101 are both less than 45 degrees to prevent difficult disassembly caused by clamping during installation or disassembly.

[0041] When the upper fixed end cap 1 is magnetically attracted and clamped with the replacement nozzle 2, the sealing cap a5 and the sealing cap b6 are respectively in close contact with the sealing cap d13 and the sealing cap c12, and all four are made of rubber.

[0042] The working principle of the present utility model is as follows:

[0043] (1) The fixed end cap 1 is fixed at the threaded port at the bottom of the intelligent greasing device 14 through the thread inside the threaded ring 101, and the conventional grease delivery pipe 15 is inserted into the nozzle port 201.

[0044] (2) When clamping nozzle ports 201 of different models and sizes onto the fixed end cap 1, due to the arrangement of the magnetic ring a501 and the magnetic ring b1301, it is convenient for the operator to perform precise coaxial positioning. Once there is a deviation of skew, the upper and lower magnetic poles of the magnetic ring a501 and the magnetic ring b1301 are the same and thus repel each other; at the same time, the arrangement of the magnetic block a601 and the magnetic block b1201 can ensure the attraction of opposite-sex magnetic poles during installation. Note that at this time, the attraction of magnetic poles occurs through their respective sealing caps and they do not come into direct contact.

[0045] (3) In step (2), due to the dual magnetic attraction, it is extremely convenient for the connection of the upper and lower layers. At this time, due to the effect that "the magnetic pole of the magnetic block a601 corresponding to the slot block 701 facing down is the same as the magnetic pole of the block 1101 corresponding to the magnetic block b1201 facing up", the block 1101 only penetrates into the fixed slot 7 and is not locked, that is, the slot block 701 and the block 1101 do not come into direct contact; at this time, the operator only needs to rotate the lower replacement nozzle 2 by about 45 degrees to complete the installation; since the magnetic poles of the corresponding magnetic blocks a601 and magnetic blocks b1201 above and below are the same after rotation, a repulsive force in the up and down direction will be generated, and the slot block 701 and the block 1101 are clamped with each other to prevent repulsion, and the friction between them will also increase and thus be sufficient to prevent rotation, finally achieving the locking effect.

[0046] (4) According to the above principle, during disassembly, only the replacement nozzle 2 needs to be rotated (either forward or backward). At this time, due to the magnetic attraction, it will not fall off, and then it can be pulled down through the replacement nozzle 2.

[0047] (5) The lubricating grease in the intelligent greasing device 14 flows into the mechanical structure to be lubricated in sequence along the threaded ring 101, the grease wall a8, the grease wall b9, the nozzle port 201, and the grease delivery pipe 15.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model, as long as they do not depart from the spirit and scope of the technical solutions of the present utility model, should be covered within the scope of the claims of the present utility model.
