[0002] In production operations, the machine needs to be oiled to make it run normally. However, at present, operators are often required to oil the machine at the vertical oil filling port. Because there will be oil stains around, it not only greatly hinders the progress of oil filling, but also poses a safety hazard to operators. Moreover, this oil filling method is extremely slow and takes a lot of time.

[0003] As an important tool for mechanical equipment maintenance, the oil injection device is widely used in lubrication systems in industries such as automobiles, tractors, and construction machinery. Its core function is to provide mechanical equipment with a timely and quantitative amount of lubricating oil to reduce the loss caused by friction and wear during the operation of the equipment, thereby extending the service life of the equipment. Therefore, designing a maintenance oiler that does not require disassembly becomes a problem that needs to be solved. Utility Model Content

[0007] Preferably, the disassembly-free installation mechanism further comprises a first card slot and a second card slot; the first card slot is provided on the housing and has a plurality of first card slots; the second card slot is provided on the spring hose and has a plurality of second card slots.

[0008] Preferably, the disassembly-free installation mechanism further comprises a first clamping block and a sliding block; the first clamping block is arranged on the first sliding sleeve; and the sliding block is slidably arranged on the housing in a horizontal straight line direction.

[0009] Preferably, the disassembly-free installation mechanism further includes a first contact block; the first contact block is arranged on the sliding block, and the first contact block is in the shape of an oblique trapezoid.

[0010] Preferably, the filter mechanism comprises a mounting sleeve and a filter port; the mounting sleeve is slidably disposed on the housing in a vertical direction; and the filter port is disposed on the mounting sleeve and is located above the mounting sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model can ensure that the equipment is firmly installed by setting a shell, a first fixed sleeve and a first sliding sleeve, and then the lubricating oil enters through the oil gun interface.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figure 1 and Fig.12As shown, the disassembly-free refueling and maintenance oiler comprises a shell 1, a spring hose 2 arranged on the shell 1 for uniform oil supply, a hollow connecting seat 3 arranged on the shell 1 for connecting to the oil filling port, an oil gun interface 4 connected to the oil gun outlet, and a disassembly-free installation mechanism 5 connected to the shell 1, the disassembly-free installation mechanism 5 comprises a first fixed sleeve 51 and a first sliding sleeve 52 slidingly matched with the first fixed sleeve 51, the refueling and maintenance oiler also comprises a filtering mechanism 6 for filtering the oil, the shell 1 can be optionally a hollow cylinder of a bent pipe, a spring is arranged in the spring hose 2, and the side of the spring hose 2 sliding into the shell 1 is made of a hard material, the spring can greatly enhance the adaptability of the spring hose 2, can be flexibly bent, protect and extend the service life of the spring hose 2, and preferably, one end of the spring hose 2 inserted into the shell 1 can be provided with a rubber sealing ring or other material with a good sealing effect, which can improve the tightness of the connection between the spring hose 2 and the shell 1, avoid leakage of the lubricating oil when passing through the spring hose 2 and the shell 1, and improve the installation service life of the spring hose 2.

[0031] In the initial state, the first sliding sleeve 52 is always away from the first fixed sleeve 51 under the action of the first return spring 54, and in this state, the first clamping block 57 can drive the first contact block 59 and the second clamping block 583 provided on the sliding block 58 to slide toward the first clamping groove 55 and the second clamping groove 56 until the second clamping block 583 is engaged with the spring hose 2. In the disassembled state, it is only necessary to slide the first sliding sleeve 52 toward the position of the first fixed sleeve 51, and the second spring can drive the sliding block 58 to slide away from the second clamping groove until the second clamping block 583 is retracted to the housing 1. The first card slot is opened on the upper part to complete the disassembly. By arranging a spring in the spring hose 2, it can be flexibly bent to protect and extend the service life of the spring hose 2. The hollow connecting seat 3 can be connected to the oil filling port of the equipment without removing the oil filling port. The setting of the shell 1 and the spring hose 2 allows the lubricating oil to be guided from the inside of the shell 1 to the outside, thereby allowing the operator to inject lubricating oil into the equipment through an externally connected oiler box without disassembling the equipment, so that the oiling work can be completed quickly without disassembling the equipment. The design is easy to operate, safe, and the structure is easy to understand.

[0032] See also Figure 1-Figure 6 As shown, the disassembly-free installation mechanism 5 also includes a positioning rod 53 and a first return spring 54; the positioning rod 53 is arranged on the first fixed sleeve 51 and the first sliding sleeve 52; the first return spring 54 is arranged on the positioning rod 53, and the first fixed sleeve 51 and the first sliding sleeve 52 are both provided with an avoidance groove for the positioning rod 53 to pass through, and the two ends of the first return spring 54 are respectively fixed to the ends of the positioning rod 53 and the first sliding sleeve 52.

[0033] When the spring hose 2 is to be installed with the housing 1, the first sliding sleeve 52 is first slid along the guide rod to a position close to the first fixed sleeve 51, and the first return spring 54 is compressed during this process. As the first sliding sleeve 52 slides, the first return spring 54 gradually releases potential energy, driving the first sliding sleeve 52 to slide horizontally relative to the first fixed sleeve 51, until the first sliding sleeve 52 and the first fixed sleeve 51 are tightly fitted and locked, thereby completing the installation.

[0034] See also Figure 8-Figure 9 As shown, the disassembly-free installation mechanism 5 also includes a first card slot 55 and a second card slot 56; the first card slot 55 is opened on the shell 1 and has a plurality of them; the second card slot 56 is opened on the spring hose 2 and has a plurality of them, the first card slot 55 and the second card slot 56 have the same shape and are both square in shape, four first card slots 55 are opened in a circular array along the outer edge of the shell 1, and four second card slots 56 are opened in a circular array along the outer edge of the spring hose 2, and the positions of the first card slot 55 and the second card slot 56 correspond to each other.

[0035] When inserting the spring hose 2 into the housing 1, it is necessary to ensure that the second slot 56 provided on the spring hose 2 corresponds to the position of the first slot 55 provided on the housing 1. When the spring hose 2 is fully inserted into the housing 1, the second slot 56 is aligned with the first slot 55, and the spring hose 2 can be fixed in the housing 1 through a locking mechanism (not described), realizing installation without disassembly.

[0036] See also Fig. 9 As shown, the disassembly-free installation mechanism 5 also includes a first clamping block 57 and a sliding block 58; the first clamping block 57 is arranged on the first sliding sleeve 52; the sliding block 58 is slidably arranged on the shell 1 in the horizontal straight direction, and the first sliding sleeve 52 is provided with a sliding chamber 581 for installing the first clamping block 57. There are four first clamping blocks 57 along the edge circumference array of the first sliding sleeve 52, and the first clamping blocks 57 correspond to the first clamping groove 55 and the position of the first clamping groove 55. A limiting block 11 for limiting the horizontal straight sliding direction of the sliding block 58 is arranged on the shell 1, and the sliding block 58 and the limiting block 11 are slidably matched. A second return spring 582 is arranged on the sliding block 58, and the two ends of the second return spring 582 are respectively fixed to the ends of the sliding block 58 and the limiting block 11.

[0037] When the first sliding sleeve 52 slides horizontally and linearly toward the position of the first fixed sleeve 51, the first clamping block 57 slides synchronously in the sliding chamber 581. Since the sliding block 58 is limited in its horizontal and linear sliding direction by the limiting block 11, the first clamping block 57 will contact the sliding block 58 during the sliding process and push the sliding block 58 to slide horizontally and linearly along the limiting block 11. Through the interaction between the first clamping block 57 and the sliding block 58, and the reset action of the second reset spring 582, the spring hose 2 and the housing 1 can be installed and removed without disassembly.

[0038] See also Figure 9-10 As shown, the disassembly-free installation mechanism 5 also includes a first contact block 59; the first contact block 59 is arranged on the sliding block 58, and the first contact block 59 is in the shape of an oblique trapezoid. The other end of the sliding block 58 is provided with a second clamping block 583 which is mutually engaged with the second clamping groove 56. The shape of the second clamping block 583 is an inverted oblique trapezoid, and is arranged inversely to the first contact block 59. The shape of the second clamping block 583 matches the shape of the second clamping groove 56 and the first clamping groove 55.

[0039] In the initial state, the first return spring 54 pushes the first sliding sleeve 52 to the side away from the first fixed sleeve 51, and at the same time drives the first clamping block 57 to contact the first contact block 59, so that the sliding block 58 slides along the limiting block 11 until the second clamping block 583 is engaged in the second clamping groove 56 of the spring hose 2. When the spring hose 2 needs to be installed in the housing 1, the first sliding sleeve 52 is first pushed toward the first fixed sleeve 51 along the guide direction to compress the first return spring 54. In this process, the oblique design of the first clamping block 57 and the first contact block 59 causes the sliding block 58 to slide along the limiting block 11 to a position close to the first clamping groove 55 and the second clamping groove 56. At the same time, driven by the sliding block 58, the second block 583 withdraws from the first slot 55 and compresses the second return spring 582. As the first sliding sleeve 52 continues to move, when the second slot 56 of the spring hose 2 is aligned with the first slot 55, the second return spring 582 releases energy, pushing the sliding block 58 and the second block 583 to slide along the limiting block 11, so that the second block 583 is inserted into and engaged in the second slot 56, thereby completing the rapid installation of the spring hose 2 and the housing 1.

[0040] See also Figure 5-Figure 12As shown, the filter mechanism 6 includes a mounting sleeve 61 and a filter port 62; the mounting sleeve 61 is slidably arranged on the shell 1 in the vertical direction; the filter port 62 is arranged on the mounting sleeve 61 and is located above the mounting sleeve 61, the mounting sleeve 61 is provided with a plurality of positioning blocks 6111, a mounting groove 611 for inserting the positioning blocks 6111 is provided on the hollow connecting seat 3, a threaded mounting hole 612 is provided on the mounting groove 611, a positioning hole 613 corresponding to the position of the threaded mounting hole 612 is provided on the positioning block 6111, the positioning hole 613 and the threaded mounting hole 612 are both threadedly connected with a locking rod 614, and the locking rod 614 is used to thread the mounting sleeve 61 and the positioning block 6111 to the hollow connecting seat 3.

[0041] When the filter port 62 needs to be quickly installed and removed, first insert the positioning block 6111 into the position of the installation groove 611 on the installation sleeve 61. At this time, the positioning hole 613 on the positioning block 6111 and the threaded installation hole 612 on the hollow connecting seat 3 can be driven to the position, and then the locking rod 614 is rotated into the positioning hole 613 and the threaded installation hole 612. At this time, the filter net can be quickly installed.
