Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, the use of directional terms such as "upper, lower, top, side" in the absence of a contrary intention is generally meant to refer to the upper, lower, top, side as illustrated in the accompanying drawings.
According to the utility model discloses an aspect provides an oiling formula bolt lag, oiling formula bolt lag includes lag body 1, lag body 1 is including the inner chamber 2 and the injeciton that is used for the screw rod of cover nut and bolt the wall portion of inner chamber 2, be provided with on the wall portion and supply lubricating oil to get into the inlet port 11 of inner chamber. Preferably, the oil injection bolt protective sleeve is made of a material which is strong in corrosion resistance and durable, such as polypropylene. Through the utility model discloses an oiling formula bolt lag, after large-scale object is fixed to be accomplished, will expose in the screw rod that is used for fixed nut and bolt in external environment arranges oiling formula bolt lag in, make it isolated with external environment, not only can protect nut and bolt, can also effectually prevent that nut and bolt from taking place to rust, corrode the scheduling problem. Simultaneously, in follow-up maintenance, through the inlet port 11 that sets up on the oiling formula bolt protective sheath, can also be as required under the condition of not taking off oiling formula bolt protective sheath directly to add lubricating oil in the oiling formula bolt protective sheath, realize at any time carrying out lubricated processing of refueling to nut and bolt, it is safe convenient. The diameter of the oil inlet hole 11 is designed according to the actual requirements of the screw diameter of the bolt, the amount of injected lubricating oil and the like.
Wherein, as shown in fig. 1 to fig. 3, for an embodiment of the oil injection type bolt protection sleeve of the present invention, the wall portion includes a side wall and a top wall disposed on the top end of the side wall, and the oil inlet hole 11 is disposed on the top wall. Because the oil inlet hole 11 is positioned on the top wall, lubricating oil can be conveniently injected into the oil injection type bolt protective sleeve. On the other hand, when lubricating oil is injected into the oil injection type bolt protecting sleeve, the lubricating oil can flow downwards from the top wall to the side wall, and therefore the nut and the bolt in the oil injection type bolt protecting sleeve can be lubricated by the lubricating oil.
Preferably, the oil injection type bolt protecting sleeve further comprises a cap which is detachably mounted on the oil inlet hole 11, the cap can be used for blocking the oil inlet hole 11, and the cap can adopt a blocking mode which is feasible in the prior art. When lubricating oil needs to be injected into the oil injection type bolt protecting sleeve, the lubricating oil can be directly injected into the oil injection type bolt protecting sleeve only by detaching the cap to expose the oil inlet hole 11, and the oil inlet hole 11 is blocked by the cap after the injection is finished. Because the oil inlet hole 11 is blocked by the cap, dust and impurities in the external environment cannot enter the inner cavity 2 of the oiling type bolt protective sleeve from the oil inlet hole 11 to pollute the lubricating oil after the lubricating oil is injected and in a daily placing state. On the other hand, the cap can be detached at any time, so that the oil inlet hole 11 is convenient to maintain and clean at any time.
In addition, the bottom of lag body 1 can also outwards extend and form antiskid portion 12, through antiskid portion 12 can make stable the placing on the plane of the object that nut and bolt are fixed of oiling formula bolt lag, avoids oiling formula bolt lag to take place to remove for the plane of object because external reasons such as strong wind, artificial touching.
Preferably, the anti-slip part 12 comprises an annular groove 121 arranged on the bottom surface of the side wall and an anti-slip rubber ring arranged in the annular groove 121, and the anti-slip rubber ring can increase the friction force with the object plane and prevent the oil injection type bolt protective sleeve from moving relative to the object plane. On the other hand, after long-term use, the anti-skid rubber ring can be detached from the annular groove 121 at any time, and a new anti-skid rubber ring is replaced according to the wear degree of the anti-skid rubber ring so as to keep the anti-skid effect.
In addition, the side wall comprises an upper part and a lower part which are sequentially arranged from the top wall to the bottom, when the nut and the screw rod of the bolt are arranged in the oil injection type bolt protective sleeve, the nut is arranged at the bottom of the lower part, and the screw rod of the bolt is arranged in the residual space and the upper part of the lower part. Preferably, the outer diameter of said upper portion of the oiled bolt boot is smaller than the outer diameter of said lower portion. Further, the outer diameter of the upper portion is not smaller than the diameter of the screw of the bolt, and the outer diameter of the lower portion is not smaller than the diameter of the nut. Further, the nut and the bolt screw may be placed in the oil-filled bolt protecting sleeve in a manner feasible in the prior art, for example, the oil-filled bolt protecting sleeve may be directly sleeved on the nut from the top of the bolt screw downwards, or the lower portion is sleeved on the nut before the upper portion is sleeved on the bolt screw.
Preferably, as shown in fig. 4, the inner wall of the upper portion is provided with a thread for screwing the screw of the bolt. Due to the adoption of the threaded connection mode, the screw rod of the bolt can be firmly arranged in the oil injection type bolt protective sleeve. More specifically, a polygonal body for a wrench to be sleeved is arranged at the joint of the outer surfaces of the upper part and the lower part. Preferably, the polygonal body is a regular hexagonal body, so that a wrench can be conveniently fixed on the regular hexagonal body for operation. During the in-service use, firstly, the oiling formula bolt lag is screwed on the screw rod of bolt through threaded connection, later with spanner and regular hexagon physique fixed, rethread spanner further fastens oiling formula bolt lag. When the formula bolt lag of pouring oil under needs are dismantled, it is fixed with regular hexagon physique earlier, rethread reverse rotation spanner for the formula bolt lag of annotating oil is lifted off from the screw rod of bolt, convenient operation.
In addition, the oiling formula bolt lag can integrated into one piece.
To sum up, through the utility model discloses an oiling formula bolt lag, after large-scale object is fixed to be accomplished, will expose and be used for fixed nut and bolt's screw rod to arrange oiling formula bolt lag in external environment, make it isolated with external environment, not only can protect nut and bolt, can also effectually prevent that nut and bolt from taking place to rust, corrode the scheduling problem. When a large object needs to be moved or disassembled, the oil injection type bolt protective sleeve can be conveniently and durably disassembled to carry out follow-up disassembling work of the nut and the bolt. Simultaneously, through the inlet port 11 that sets up on the oiling formula bolt lag, can also be as required under the condition of not taking off oiling formula bolt lag directly to adding lubricating oil in the oiling formula bolt lag, realize at any time carrying out lubricated processing of refueling to nut and bolt, it is safe convenient.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. In the technical idea scope of the present invention, it is possible to provide the technical solution of the present invention with a plurality of simple modifications, including combining each specific technical feature in any suitable manner, and in order to avoid unnecessary repetition, the present invention does not provide additional description for various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
