Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a fixing bolt which is convenient for storing lubricating oil. Background Art

[0002] A bolt is a screw used to fix objects. It usually has a head and a thread. It can be used with a nut to connect two or more parts. Bolts are usually made of metal and have different specifications and sizes. They can be selected and used according to specific needs. They are widely used in engineering, construction, machinery manufacturing and other fields and are a common connection element.

[0003] In order to prevent the existing bolts from rusting during use, an oil storage mechanism is added inside the bolts to store lubricating oil and reduce the rust rate of the bolts.

[0004] For example, an oil outlet bolt with publication number CN204357888U has an oil storage tank filled with lubricating oil. When rust occurs, the piston squeezes the internal space of the oil storage tank, and the lubricating oil will seep out from the oil outlet hole to lubricate the joint between the screw and the mechanical parts. It is simple to operate, easy to use, and has high oil outlet and lubrication efficiency. However, the device still has certain defects;

[0005] No sealing mechanism is provided at the oil outlet channel. Since the bolt rotates during use, the orientation of the oil outlet channel in the bolt cannot be guaranteed. When the oil outlet channel is positioned downward, the lubricating oil in the bolt is likely to overflow through the oil outlet channel under the action of gravity, thereby causing a waste of lubricating oil.

[0006] Therefore, we propose a fixing bolt which is convenient for storing lubricating oil, so as to solve the above-mentioned problems. Utility Model Content

[0007] The utility model aims to provide a fixing bolt which is convenient for storing lubricating oil, so as to solve the problem proposed in the above-mentioned background technology that the existing oil outlet bolts on the market are not provided with a sealing mechanism at the oil outlet channel position, and since the bolt rotates during use, the orientation of the oil outlet channel position in the bolt cannot be guaranteed. When the oil outlet channel is positioned downward, the lubricating oil in the bolt is easy to overflow through the oil outlet channel under the action of gravity, thereby causing the problem of waste of lubricating oil.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing bolt for storing lubricating oil, comprising a threaded rod, a first oil storage chamber and a second oil storage chamber, a threaded head is installed on the left side of the threaded rod, and the first oil storage chamber and the second oil storage chamber are opened inside the threaded rod, a piston assembly is arranged inside the second oil storage chamber, and a first movable rod is installed on the right side of the piston assembly, the first oil storage chamber and the second oil storage chamber are connected by an oil replenishing hole, a second movable rod passes through the first oil storage chamber, and a movable ball is installed on the right side of the second movable rod, a movable block is arranged inside the first oil storage chamber, and a slide groove is opened at the bottom of the movable block, and a limiting rod is installed inside the slide groove through a telescopic spring, a sealing ball is installed above the movable block, and the sealing ball can abut against the oil outlet.

[0009] Preferably, the threaded rod is divided into two parts by a first oil storage chamber and a second oil storage chamber, and the two separated parts can be connected by welding.

[0010] By adopting the above structural design, when making the fixing bolt, the first oil storage chamber and the second oil storage chamber are opened on the segmented threaded rod, and the components in the first oil storage chamber and the second oil storage chamber are installed and welded inside thereof, and then the threaded rod is welded, thereby completing the overall production of the threaded rod.

[0011] Preferably, an oil outlet is provided above the threaded rod, and the oil outlet is communicated with the interior of the first oil storage chamber.

[0012] With the above structural design, oil can be delivered to the first oil storage chamber and the second oil storage chamber through the oil outlet, and the lubricating oil in the first oil storage chamber and the second oil storage chamber can also be squeezed out through the oil outlet to lubricate the threaded rod and prevent the threaded rod from rusting.

[0013] Preferably, the piston assembly fits against the inner wall of the second oil storage chamber, and a movable connection structure is formed between the piston assembly and the second oil storage chamber.

[0014] With the above structural design, the first movable rod drives the piston assembly to move leftward, so that the lubricating oil in the first oil storage chamber and the second oil storage chamber moves rightward and is squeezed out through the oil outlet.

[0015] Preferably, the second movable rod passes through the threaded head, and rubber rings are installed on the outer sides of the first movable rod and the second movable rod.

[0016] By adopting the above structural design, the friction force of the first movable rod and the second movable rod is increased, so that the first movable rod and the second movable rod will not move when no force is applied.

[0017] Preferably, the lower surface of the movable block is designed to have an arc-shaped structure, and the movable block is located below the oil outlet.

[0018] By adopting the above-mentioned structural design, the movable ball is pushed to the right by the second movable rod, and the movable ball pushes the movable block to move upward. At this time, the telescopic spring is in a stretched state. The movable block moves upward, driving the sealing ball to move upward to seal the oil outlet to prevent the lubricating oil from overflowing. Similarly, when the threaded rod needs to be lubricated, the second movable rod and the movable ball are moved in the opposite direction to make the movable ball away from the movable block. The movable block moves downward under the action of the rebound force of the telescopic spring, driving the sealing ball to move downward and away from the oil outlet, thereby facilitating the discharge of the lubricating oil in the first oil storage chamber.

[0019] Preferably, the limiting rod is fixed to the inner bottom of the first oil storage chamber, and a sliding connection structure is formed between the limiting rod and the slide groove.

When making the fixing bolt, the first oil storage chamber 3 and the second oil storage chamber 4 are opened on the segmented threaded rod 1, and the parts in the first oil storage chamber 3 and the second oil storage chamber 4 are connected. After the components are installed and welded inside, the threaded rod 1 is then welded to complete the overall production of the threaded rod 1. An oil outlet 5 is provided above the threaded rod 1, and the oil outlet 5 is communicated with the interior of the first oil storage chamber 3. Oil can be delivered to the first oil storage chamber 3 and the second oil storage chamber 4 through the oil outlet 5. At the same time, the lubricating oil in the first oil storage chamber 3 and the second oil storage chamber 4 can also be squeezed out through the oil outlet 5 to lubricate the threaded rod 1 and prevent the threaded rod 1 from rusting. A piston assembly 6 is provided inside the second oil storage chamber 4. The piston assembly 6 is fitted with the inner wall of the second oil storage chamber 4, and a movable connection structure is formed between the piston assembly 6 and the second oil storage chamber 4. The piston assembly 6 is driven to move to the left by the first movable rod 7, so that the lubricating oil in the first oil storage chamber 3 and the second oil storage chamber 4 moves to the right and is squeezed out through the oil outlet 5.
