Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubricating oil injection tooling, in particular to a lubricating oil injection tooling for a bearing. Background Art
[0002] In the prior art, some bearings need to be used with lubricating oil. In this case, a filling tool is needed to add lubricating oil to the rotor of the bearing. In the prior art, the filling tool used varies according to the viscosity of the lubricating oil, and the filling tool has many different models and styles.
[0003] The present application document is mainly aimed at improving the grease gun. When the grease gun in the prior art is in use, the grease can only be ejected straight forward from the muzzle. At this time, if the grease ejected by the grease gun is to enter the ball bearing of the gear, the muzzle and the ball bearing of the gear should be approximately perpendicular to each other or have a certain small inclination angle to ensure that the lubricating oil in the grease gun can be injected into the ball bearing of the gear. When faced with some installed bearings, the front space of some bearings is extremely narrow and there is no special grease filling port. At this time, the muzzle of the grease gun can only be inserted parallel to the ball bearing. At this time, it is basically impossible to inject grease into the bearing. Therefore, a bearing lubricating oil injection tooling is needed to improve this narrow situation. Utility Model Content
[0004] The utility model aims to provide a lubricating oil injection tool for a bearing to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lubricating oil injection tool for a bearing, comprising a grease gun body, a transmission pipe is fixedly arranged on one side of the surface of the grease gun body, and a guide mechanism for controlling the outflow direction of grease is fixedly arranged on the end of the transmission pipe away from the grease gun body, and the guide mechanism comprises an oil outlet head, an oil outlet channel, a first through hole, a movable sleeve, and a second through hole. An oil outlet head is fixedly arranged on the end of the transmission pipe away from the grease gun body, an oil outlet channel is fixedly arranged on the middle part of the inner side of the oil outlet head, a first through hole is opened on one side of the surface of the oil outlet head, and the first through hole and the oil outlet channel form an angle of 90°, a movable sleeve is movably sleeved on the outer surface of the oil outlet head, and a second through hole is opened on the outer surface of the movable sleeve.
[0006] Preferably, a connecting sleeve is provided on the outer surface of the transmission tube through a threaded engagement, and the connecting sleeve is fixedly connected to the movable sleeve at one end close to the movable sleeve. By rotating the connecting sleeve, the connecting sleeve and the movable sleeve can be moved left and right and rotated along the transmission tube under the action of the thread. When the movable sleeve moves left and right and rotates, the first through hole and the second through hole will be misaligned or aligned.
[0007] Preferably, a connecting rod is fixedly provided on one side of the surface of the movable sleeve, and a sealing plug is fixedly provided on the middle part of the surface of the connecting rod. When the movable sleeve moves toward the transmission pipe, the sealing plug will gradually be inserted into the oil outlet channel. When the sealing plug blocks the oil outlet channel, the first through hole and the second through hole will be aligned. Since the first through hole and the oil outlet channel form an angle of 90°, the oil outlet direction can be changed, so that the lubricating oil squeezed out of the device can be squeezed out from the side of the oil outlet head, thereby forming an oil supply path with an angle of 90° with the ball of the bearing again. In this way, as long as the transmission pipe of the device can be inserted in front of the bearing, the lubricating oil can be added in the direction of the ball of the bearing parallel to the bearing.
[0008] Preferably, a ball is movably engaged inside the transmission tube, and a spring is provided on one side of the ball inside the transmission tube. The spring pushes the ball to seal the transmission tube, and this seal is a one-way seal, thereby preventing foreign matter from entering the grease gun body through the transmission tube and contaminating the grease.
[0009] Preferably, a handle is fixedly provided on one side of the surface of the grease gun body, and the handle can be used to conveniently hold and use the device.
[0010] Preferably, a storage tube is provided at the lower end of the grease gun body, and the lubricating oil to be added to the bearing can be conveniently stored through the storage tube.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model rotates the connecting sleeve through a thread, so that the connecting sleeve and the movable sleeve can move and rotate along the transmission pipe toward the direction of the grease gun body, so that the sealing plug will gradually be inserted into the oil outlet flow channel, and when the sealing plug blocks the oil outlet flow channel, the first through hole and the second through hole will be aligned; in this way, the oil outlet direction can be changed, so that the lubricating oil squeezed out of the device can be squeezed out from the side of the oil outlet head, so that an oil supply path with a 90° angle can be formed with the ball of the bearing again, so that as long as the transmission pipe of the device can be inserted in front of the bearing, the lubricating oil can be added in parallel with the bearing toward the ball direction of the bearing, thereby improving the use effect of the device.
[0013] 2. When the utility model is used, the oil outlet direction of the device can be changed conveniently and quickly. The oil outlet direction can be switched by rotating the connecting sleeve, controlling whether the first through hole and the second through hole are misaligned, and controlling whether the sealing plug blocks the oil outlet channel. The device is easy to operate and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides a technical solution: a lubricating oil injection tool for a bearing, comprising a grease gun body 1, a transmission pipe 2 is fixedly arranged on one side of the surface of the grease gun body 1, and a guide mechanism for controlling the outflow direction of grease is fixedly arranged on the end of the transmission pipe 2 away from the grease gun body 1, and the guide mechanism comprises an oil outlet head 3, an oil outlet flow channel 4, a first through hole 5, a movable sleeve 6, and a second through hole 7. An oil outlet head 3 is fixedly arranged on the end of the transmission pipe 2 away from the grease gun body 1, and an oil outlet flow channel 4 is fixedly arranged on the middle part of the inner side of the oil outlet head 3. A first through hole 5 is opened on one side of the surface of the oil outlet head 3, and the first through hole 5 and the oil outlet flow channel 4 form an angle of 90°. A movable sleeve 6 is movably sleeved on the outer surface of the oil outlet head 3, and a second through hole 7 is opened on the outer surface of the movable sleeve 6.
[0021] The outer surface of the transmission pipe 2 is provided with a connecting sleeve 8 through a threaded movably screwed connection. One end of the connecting sleeve 8 close to the movable sleeve 6 is fixedly connected to the movable sleeve 6. By rotating the connecting sleeve 8, the connecting sleeve 8 and the movable sleeve 6 can be moved left and right and rotated along the transmission pipe 2 under the action of the thread. When the movable sleeve 6 moves left and right and rotates, the first through hole 5 and the second through hole 7 are misaligned or aligned.
[0022] A connecting rod 9 is fixedly provided on one side of the surface of the movable sleeve 6, and a sealing plug 10 is fixedly provided on the middle part of the surface of the connecting rod 9. When the movable sleeve 6 moves toward the transmission pipe 2, the sealing plug will gradually be inserted into the oil outlet channel 4. When the sealing plug 10 blocks the oil outlet channel 4, the first through hole 5 and the second through hole 7 are aligned. Since the first through hole 5 and the oil outlet channel 4 form an angle of 90°, the oil outlet direction can be changed, so that the lubricating oil squeezed out by the device can be squeezed out from the side of the oil outlet head 3, so as to form an oil supply path with an angle of 90° with the ball 11 of the bearing again. In this way, as long as the transmission pipe 2 of the device can be inserted in front of the bearing, the lubricating oil can be added in the direction of the ball 11 of the bearing in parallel with the bearing.
[0023] A ball 11 is movably engaged inside the transmission tube 2, and a spring 12 is provided on one side of the ball 11 inside the transmission tube 2. The spring 12 pushes the ball 11 to seal the transmission tube 2, and the seal is a one-way seal, thereby preventing foreign matter from entering the grease gun body 1 through the transmission tube 2 and contaminating the grease;
[0024] A handle 13 is fixedly provided on one side of the surface of the grease gun body 1, and the handle 13 can be used to conveniently hold and use the device;
[0025] A storage tube 14 is provided at the lower end of the grease gun body 1, and the lubricating oil to be added to the bearing can be conveniently stored through the storage tube 14.
[0026] Working principle: When using the device, there are two modes for adding grease. When there is enough space in front of the bearing to be added, the lubricating oil can be vertically added to the ball 11 of the bearing; at this time, the state of the oil outlet 3 and the movable sleeve 6 should be as follows: Figure 4 As shown, at this time, the sealing plug 10 and the oil outlet channel 4 are mutually offset, and the first through hole 5 and the second through hole 7 are mutually offset, so that the lubricating oil squeezed out by the grease gun body 1 can only flow out from the oil outlet channel 4, so that the lubricating oil can be added to the ball 11 of the vertical bearing; this is also the filling method of the grease gun in the prior art;
[0027] If the space in front of the bearing is extremely narrow, and there is only space for the transmission tube 2 to be inserted in parallel, the connecting sleeve 8 can be screwed to make the connecting sleeve 8 and the movable sleeve 6 move and rotate along the transmission tube 2 toward the grease gun body 1, so that the sealing plug 10 is gradually inserted into the oil outlet channel 4. When the sealing plug 10 blocks the oil outlet channel 4, the first through hole 5 and the second through hole 7 are aligned. Since the first through hole 5 and the oil outlet channel 4 form an angle of 90°, the oil outlet direction can be changed, so that the lubricating oil squeezed out by the device can be squeezed out from the side of the oil outlet head 3, so that an oil supply path with an angle of 90° can be formed with the ball 11 of the bearing again. In this way, as long as the transmission tube 2 of the device can be inserted in front of the bearing, the lubricating oil can be added in parallel with the bearing toward the ball 11 of the bearing, thereby improving the use effect of the device.
[0028] When the device is in use, the oil outlet direction of the device can be changed quickly and conveniently. The oil outlet direction can be switched by rotating the connecting sleeve 8, controlling whether the first through hole 5 and the second through hole 7 are misaligned, and controlling whether the sealing plug 10 blocks the oil outlet channel 4. The device is easy to operate and use.
