To this end, an embodiment of the present invention provides a lubricant injection mechanism, and specifically please refer to fig. 1-2, fig. 1 is a schematic structural diagram of the lubricant injection mechanism in a non-plugging state, and fig. 2 is a partial structural diagram of the lubricant injection mechanism in a plugging state.

As shown in fig. 1 and 2, the lubricant injection mechanism according to the embodiment of the present invention includes a filling gun 1 and a receiving nozzle 2, wherein the filling gun 1 is provided with a filling port 121a-1, and the receiving nozzle 2 is provided with a receiving port 211; one of the filling gun 1 and the receiving nozzle 2 is provided with an elastic guide mechanism 3, the filling gun 1 can be inserted into the receiving nozzle 2 in a filling state, and the elastic guide mechanism 3 can guide the alignment of the filling port 121a-1 and the receiving port 211.

And, because the elastic guide mechanism 3 has certain elasticity, can also reduce the wearing and tearing in the direction process.

It should be noted that although the embodiments of the present invention are designed primarily for the lubrication of the wheels of a pallet, it is clear that the lubricant injection mechanism provided by the present invention is not limited to lubrication of the wheels of a pallet; that is, the application field is not actually used as a limitation to the scope of the implementation of the lubricant injection mechanism provided in the present invention, and the lubricant injection mechanism can be actually used for the injection of lubricant in other devices.

In addition, the embodiment of the present invention does not limit the type of the lubricant, and the specific requirement is determined by combining with the actual application scenario. Still taking the example of wheel lubrication applied to a sintering pallet, the lubricant may be lubricating oil or the like.

Further elaborating, in practical applications, the receiving nozzle 2 is installed on a component to be lubricated, the position of the component to be lubricated is usually not adjustable, and on the premise that the receiving nozzle 2 cannot move relative to the component to be lubricated, alignment adjustment between the filling gun 1 and the receiving nozzle 2 is actually adjusting the position of the filling gun 1; that is, the filling gun 1 is urged to displace by the elastic guide mechanism 3 so that the filling port 121a-1 and the receiving port 211 are aligned.

As described above, the elastic guide mechanism 3 may be provided in the filling gun 1 or in the receiving nozzle 2, and the following embodiments of the present invention will be described mainly by taking the example in which the elastic guide mechanism 3 is provided in the filling gun 1, and the embodiment of the present invention will not be described repeatedly, similarly to the case in which the elastic guide mechanism 3 is provided in the receiving nozzle 2.

In detail, the filling gun 1 can comprise an outer cylinder 11 and an inner cylinder 12 which are connected in a sliding and sealing manner, wherein the sliding and sealing connection means that the inner cylinder 12 can slide in the outer cylinder 11, and the inner cylinder 12 and the outer cylinder 11 can be sealed to avoid leakage; the inner barrel 12 can be provided with the previously described fill port 121a-1 and the outer barrel 11 can have opposing first and second ends, where with reference to FIG. 1, the first end can refer to the right end of the outer barrel 11 and the second end can refer to the left end of the outer barrel 11; the elastic guide mechanism 3 may include a plurality of elastic pieces 31, each of the elastic pieces 31 may be circumferentially spaced, one end of each of the elastic pieces 31 may be fixed to the first end of the outer cylinder 11, and the other end of each of the elastic pieces 31 may be in contact with the outer wall surface of the inner cylinder 12, and the elastic pieces 31 may gradually tilt radially inward in a direction from the first end to the second end (a direction from right to left in the drawing).

With such an arrangement, the elastic pieces 31 can enclose to form a flared opening gradually expanding from left to right, so that the filling gun 1 inserted into the receiving nozzle 2 from left to right can be guided, and the filling opening 121a-1 of the filling gun 1 and the receiving opening 211 of the receiving nozzle 2 are automatically driven to align.

The elastic sheet 31 may be made of metal, so that the fatigue deformation resistance of the elastic sheet 31 in the using process can be improved, and the service life of the elastic sheet 31 can be further ensured.

The fixing manner of the one end of the elastic sheet 31 and the first end of the outer cylinder 11 is not limited herein, and in specific implementation, a person skilled in the art may set the fixing manner according to actual needs as long as the reliable connection between the two can be ensured. For example, the elastic piece 31 may be fixed to the outer tube 11 by various means such as adhesion, caulking, screwing, and the like.

Specifically, the present invention may further include a pressing cover 16, and the pressing cover 16 may be mounted on the first end portion of the outer cylinder 11 to press and fix an end portion of the elastic sheet 31, so as to fix the elastic sheet 31 to the outer cylinder 11. The connection manner of the gland 16 and the outer cylinder 11 may be one or more of a threaded connection, a screw connection, a riveting, a welding, an adhesion, and the like, as long as reliable fixation between the gland 16 and the outer cylinder 11 can be ensured.

Further, the inner cylinder 12 may include an inner cylinder 121 and a sealing member 122 externally fitted to the inner cylinder 121, and the sealing member 122 may be made of a material having a certain elasticity, such as rubber, for sealing a gap between the inner cylinder 121 and the outer cylinder 11. The sealing member 122 may be a sealing ring or a sealing cylinder having a certain extension in the axial direction.

The other end of the spring plate 31 can contact the sealing member 122, and when the inner cylinder 12 slides in the outer cylinder 11, the spring plate 31 can slide in contact with the sealing member 122.

Further, a limit structure may be provided between the outer cylinder 11 and the inner cylinder 12 for limiting a displacement distance of the inner cylinder 12 in a direction from the second end to the first end. Referring to fig. 1, the limiting structure is specifically used for limiting the displacement distance of the inner cylinder 12 from left to right, so as to prevent the inner cylinder 12 from being separated from the outer cylinder 11 in the left-to-right direction.

Here, the embodiment of the present invention does not limit the specific form of the above-mentioned limiting structure, as long as the technical requirement of limiting can be satisfied. In the embodiment of fig. 1, the inner wall surface of the outer cylinder 11 may be provided with a second limit projection 111 extending radially inward, the outer wall of the sealing member 122 may be provided with a first limit projection 122a, and the first limit projection 122a and the second limit projection 111 may axially abut against each other to limit the inner cylinder 12.

With continued reference to fig. 1, the lubricant injection mechanism provided by the present invention may further include a first elastic member 13 and a first blocking portion 14, the inner cylinder 12 may be provided with a filling passage 121a, an end of the filling passage 121a relatively close to the first end portion may form the aforementioned filling port 121a-1, and the first elastic member 13 may interact with the first blocking portion 14 to enable the first blocking portion 14 to block an end of the filling passage 121a relatively far from the first end portion.

When in specific use, the outer cylinder 11 may be mounted on an injection component such as a lubricant injection pipe, and two ends of the first elastic member 13 may respectively abut against the first blocking portion 14 and the injection component, so as to drive the first blocking portion 14 to block the injection channel 121 a; when the lubricant starts to be injected, the liquid lubricant can exert pressure on the first blocking part 14 to drive the first blocking part 14 to open the filling channel 121a, so that the lubricant can enter the filling channel 121a and can be injected into the receiving nozzle 2 through the filling port 121a-1 of the filling channel 121 a; after the lubricant is injected, the injection component stops providing the lubricant, the pressure of the lubricant on the first blocking portion 14 is reduced, and the first elastic piece 13 can drive the first blocking portion 14 to re-block the filling channel 121a to avoid the lubricant from leaking.

The first blocking portion 14 may be spherical in shape, or at least one end of the first blocking portion 14 facing the inner cylinder 12 may have a spherical surface, so that the first blocking portion 14 can open the filling passage 121a under the action of the lubricant. In addition, the spherical surface may be designed so that the first blocking portion 14 can reliably block the filling passage 121 a.

The type of the first elastic member 13 is not limited herein, as long as the corresponding technical effects can be achieved. For example, the first elastic member 13 may be an elastic element in various forms such as an elastic ball, an elastic string, a spring, and the like. Taking a spring as an example, when acting on the first blocking portion 14, the spring may generate a compressive force or a tensile force, which is specifically related to the installation position of the first elastic member 13.

Further, a sheath 15 may be further included, and when the outer cylinder 11 is not assembled with the injection member, the sheath 15 may be attached to the second end portion of the outer cylinder 11, and both ends of the first elastic member 13 may abut against the sheath 15 and the first blocking portion 14, respectively. Therefore, the first elastic piece 13 and the first blocking part 14 can be prevented from being lost, and integrated packaging and selling of products are facilitated.

The receiving mouth 2 may have a tapered section for a plug-in fitting with the filling gun 1, and the receiving opening 211 may be located at the small-sized end of the tapered section. The generatrix of the conical section can be a straight line or an arc line.

Further, the receiving nozzle 2 may be provided with a receiving passage 21, and one end of the receiving passage 21 may form the aforementioned receiving opening 211; a second elastic element 22 and a second blocking portion 23 may also be included, the second elastic element 22 being able to interact with the second blocking portion 23 such that the second blocking portion 23 blocks the receiving opening 211.

After the filling gun 1 and the receiving nozzle 2 are completely butted, the second blocking part 23 can open the receiving port 211 under the pressure of the lubricant in the filling gun 1, so that the lubricant in the filling gun 1 enters the receiving channel 21.

The second elastic member 22 can be constructed as described above with reference to the first elastic member 13, and will not be described repeatedly. The second blocking portion 23 may be spherical or have other shapes as long as it can reliably block the closing-in port 211; in the embodiment of the present invention, a spherical solution is preferably adopted to ensure the blocking effect of the second blocking portion 23.

The invention also provides lubricant injection equipment which comprises a lubricant box, a lubricant extracting device and the lubricant injection mechanism, wherein the filling gun 1 can be connected with the lubricant extracting device, the receiving nozzle 2 can be arranged on a part to be lubricated, and the type of the part to be lubricated is associated with a specific application scene and the like.

Since the above-mentioned lubricant injection mechanism has the above technical effects, the lubricant injection device having the lubricant injection mechanism also has similar technical effects, and therefore, the detailed description thereof is omitted here.

The invention also provides a lubrication system for a pallet truck equipped with wheels, comprising a lubricant injection device as described above, in which case the part to be lubricated is a wheel, that is to say the receiving mouth 2 can be mounted on a wheel.

Since the above-mentioned lubricant injection device has the technical effects, the lubrication system of the sintering pallet with the lubricant injection device also has similar technical effects, and therefore, the detailed description thereof is omitted here.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
