Description

High-strength screw

Technical Field

The utility model relates to a screw technical field, more specifically say, it relates to a high strength screw.

Background

The screw is a tool for fastening machine parts of the object step by utilizing the physics and mathematical principles of the inclined plane circular rotation and the friction force of the object, the screw is a general expression of the fastener, and the daily screw is an indispensable industrial necessity in daily life: extremely small screws used for cameras, glasses, clocks, electronics, and the like; general screws for televisions, electric appliances, musical instruments, furniture, and the like; large screws and nuts are used for engineering, buildings and bridges; transportation equipment, airplanes, electric cars, automobiles, and the like are used with screws of different sizes. The screw has an important task in industry, and as long as there is industry on earth, the function of the screw is always important.

The screw structure usually comprises a cross groove, the screw is installed by embedding a corresponding screwdriver bit into the cross groove, and in the daily use process of people, the cross groove of the screw is worn and damaged due to over-strong force or repeated installation and uninstallation of the screw, and cannot be perfectly embedded with the screwdriver bit, so that the screw can slip and the like, and a user can usually replace the screw to solve the problems of slipping and the like; however, the screws installed on some large-scale equipment or machines are large, and the replacement of the whole screw only due to the damage of the cross groove causes economic waste.

There is a technical scheme on the existing market, and its technical essential includes the screw body, and the screw body includes the installation end, and the installation end is equipped with the locking groove, the locking inslot wall is equipped with flexible groove, and the locking inslot is embedded to have the installation piece, and installation piece one end is equipped with cross recess and control flume, and the installation piece lateral wall is equipped with the groove of sliding, and groove and control flume intercommunication slide, the inslot that slides is equipped with the fixture block, and the fixture block passes through the spring to be fixed at the groove tank bottom that slides, and the flexible inslot of fixture block one end embedding, the control flume slides and is connected with the control post, control post one end is fixed in the fixture block, and the other end stretches out outside the control flume.

In the technical scheme, the mounting block needs to be fixed on the screw body, so that the screwdriver bit can drive the whole screw to screw in and out when being embedded into the cross groove, and the technical scheme is realized by fixing one end of the clamping block at the bottom of the sliding groove through the spring and embedding the clamping block, which is well mounted by the mounting block, into the telescopic groove; owing to be fixture block and the groove tank bottom that slides through spring coupling, the fixture block is spacing, consequently, when screwdriver rotating screw, the spring can bear most bending stress, can lead to the spring to take place the transverse deformation distortion after using for a long time, the condition of fixed insecure and rocking appears, also can not reset the fixture block to the inslot that slides when user's pulling control post simultaneously, cause the installation to dismantle the condition of difficulty, the recipient can only solve this problem through changing whole installation piece, cause economic waste, consequently, need provide a new scheme and solve this problem.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a more durable high strength screw.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a high strength screw, including the installation piece, installation piece lateral wall is equipped with the groove of sliding, the inslot that slides is equipped with the fixture block, the fixture block passes through the spring to be fixed at the groove bottom of sliding, be equipped with the gusset plate between groove bottom of sliding and the fixture block, the groove bottom of sliding is equipped with the inserting groove with the gusset plate adaptation, inserting groove and gusset plate slide and are connected, the fixture block is close to the one end of spring and is equipped with and supplies gusset plate male constant head tank, the constant head tank bottom is equipped with a plurality of reinforcement hole, gusset plate one end is equipped with the anchor post of reinforcement hole adaptation, the fixture block lateral wall is equipped with the location screw, the location screw extends to in the anchor post, be equipped with the set screw in the location screw.

By adopting the technical scheme, the reinforcing plate is arranged between the bottom of the sliding groove and the clamping block, the reinforcing plate can be made of wood plates or metal plates, the bottom of the sliding groove is provided with the inserting groove, so that the reinforcing plate is generally inserted into the inserting groove and connected with the inserting groove in a sliding manner, and when the spring is stretched, the inserting groove is internally provided with a space for the reinforcing plate to pass in and out, so that the shrinking function of the spring of the original utility model can not be influenced by the existence of the reinforcing plate; meanwhile, a positioning groove matched with the reinforcing plate is formed in one end, close to the spring, of the clamping block, at least two reinforcing holes are formed in the bottom of the positioning groove, a reinforcing column matched with the reinforcing holes is formed in the other side, opposite to the reinforcing plate, of the reinforcing column, the reinforcing plate is inserted into the positioning groove, and meanwhile the reinforcing column is inserted into the reinforcing holes; then, a positioning screw hole is formed in the side wall of the clamping block and extends into the fixing column, and then a positioning screw is inserted into the positioning screw hole, so that the positioning screw is in threaded connection with the clamping block and the fixing column; because the transverse elasticity of the spring is better relative to the reinforcing plate, the deformation amplitude born by the spring is larger, and the relative amplitude born by the reinforcing plate is smaller, so that the reinforcing plate can replace the spring to bear the bending stress generated by the twisting of the screw, and meanwhile, the bending stress born by the reinforcing plate is larger, thereby improving the structural strength of the utility model, ensuring that the utility model is not easy to damage and finally achieving the purpose of economy and saving; on the other hand, fixed post on the fixed plate is inserted to the fixed orifices in, uses the set screw to fix the reference column, and the fixed orifices self has a limiting displacement to the fixed column, and the set screw has another fixed action to the fixed column, has guaranteed the connection stability between gusset plate and the fixture block through dual spacing, has reached the fixed firm purpose of gusset plate, and the gusset plate is in a detachable state simultaneously, if the gusset plate damages the user only need change the gusset plate can, reached the purpose of economic saving.

The utility model discloses further set up to: the gusset plate quantity sets up to two and arranges the spring both sides in respectively, and inserting groove, constant head tank all set up to two.

Because the screwdriver is screwing and unscrewing the utility model discloses a during the installation piece, the bending stress that the spring received is also opposite, through adopting above-mentioned technical scheme, sets up the quantity of gusset plate into two and arrange the spring both sides respectively in, also all sets up to two with it complex inserting groove and constant head tank simultaneously, makes two gusset plates bear opposite direction's bending stress respectively, guarantees that the spring is not influenced by bending stress, has finally prolonged the utility model discloses a life has reached economic saving's purpose.
