Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a special screw capable of multi-directional connection. Background Art

[0002] Screws, some people also call them "screws" (screws) and "screw rods" (screw rods). In fact, screws are a general term, while screws and screw rods are different from each other. Screws are generally called wood screws; they are the kind with a pointed head at the front end and a larger pitch, and are generally used to fasten wooden and plastic parts. Screw rods are machine screws (mechanical screws), which are the kind with a flat head at the front end, with a smaller and uniform pitch, and are generally used to fasten metal and machine parts. Screws are a general term for fasteners and a daily colloquialism. Screws are indispensable industrial necessities in daily life: such as extremely small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc. Special screws are a type of screw, made of metal with concave and convex grooves engraved on the surface. When connecting, they use the circular rotation of the inclined surface of the object and the friction force to enter the connection to achieve fastening. The application of special screws is more common.

[0003] According to Chinese patent publication number CN 216407430 U, a special screw capable of multi-directional connection is disclosed, including a screw, an adjustment block is sleeved on the outside of the screw, two slide grooves are provided on the inner side of the adjustment block, a positioning component is provided inside the slide groove, a filling block is connected between the two positioning components, a positioning block is connected to one side of the filling block, an extrusion component is provided inside the positioning block, the positioning component includes a slider connected inside the two slide grooves, a magnetic hole provided on the top of the slider, a magnetic block connected inside the magnetic hole, and the extrusion component includes a groove provided on one side of the positioning block, a bearing fixed inside the groove, and a threaded rod fixed inside the bearing. The special screw capable of multi-directional connection can facilitate the staff to connect the adjustment block and the filling block, and can adjust the depth of the screw embedded in the wall, so as to achieve the function of multi-directional connection.

[0004] However, the above device has the problem that the cross installation groove opened above the screw is in the shape of a universal tool, and the screw can be easily unscrewed maliciously, resulting in low safety. Utility Model Content

[0008] Furthermore, after using a specific tool to insert the "cross groove" opened above the tightening cap and the triangular block fixedly connected in the middle of the "cross groove", the screw rod is extended into the interior of the object by rotating the specific tool, and the fixed pad fits the surface of the object. When the tightening cap is hit by external impact, the spring fixed under the protective pad and above the fixed pad buffers the vibration force, and squeezes the spring upward through the fixed pad, which has good anti-vibration and anti-collision effects, thereby preventing someone from maliciously unscrewing the screw rod and improving safety.

[0009] Preferably, a "cross groove" is provided on the surface of the tightening cap, and a triangular block is fixedly connected to the middle of the "cross groove".

[0013] Preferably, the adjustment mechanism comprises a nut, and a first screw rod is threadedly connected to the left and right sides of the nut, and a clamping plate is fixedly connected to the left side of the first screw rod.

[0014] Furthermore, when fixing objects that require different depths, the nut is sleeved on the surface of the screw rod according to the required distance of the object. After the nut reaches the appropriate distance, the first screw rods on the left and right sides of the nut are rotated. When the first screw rod rotates, the clamping plate is pushed to fit the surface of the screw rod, and the nut is fixed to the surface of the screw rod. Then, a specific tool is used to embed the screw rod into the object, thereby achieving the effect of adjusting the length of the screw rod embedded in the object according to needs, thereby realizing the effect of multi-directional connection.

[0016] Furthermore, the thread grooves formed on the left and right surfaces of the nut facilitate installation of the two first screw rods in the thread grooves respectively.

[0017] Preferably, two clamping plates are provided, and the two clamping plates are respectively located on the left and right sides of the first screw rod.

[0018] Furthermore, the clamping plate is provided with two first threaded rods on the left and right sides of the nut, so that when the first threaded rods rotate, the two clamping plates are pushed to move simultaneously to firmly fix the nut on the surface of the screw rod.

[0019] Preferably, the nut is sleeved on the surface of the screw rod.

[0020] Furthermore, the nut is sleeved on the surface of the screw rod, which facilitates the movement of the nut on the surface of the screw rod, and the length of the screw rod can be adjusted, and the length of the screw rod extending into the interior of the object can be adjusted.

[0021] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0022] First, the utility model uses a specific tool to insert the "cross groove" opened above the tightening cap and the triangular block fixedly connected in the middle of the "cross groove", and then extends the screw rod into the interior of the object by rotating the specific tool, and the fixed pad fits the surface of the object. When the tightening cap is impacted by the outside world, the spring fixed below the protective pad and above the fixed pad buffers the vibration force, and squeezes the spring upward through the fixed pad, which has good anti-vibration and anti-collision effects, thereby preventing someone from maliciously screwing out the screw rod and improving safety.

[0023] Second, when the utility model is used to fix objects that require different depths, the nut is sleeved on the surface of the screw rod according to the required distance of the object, and the first screw rods on the left and right sides of the nut are rotated after the nut reaches the appropriate distance. When the first screw rod rotates, the clamping plate is pushed to fit the surface of the screw rod, and the nut is fixed to the surface of the screw rod. Then, a specific tool is used to embed the screw rod into the object, so that the length of the screw rod embedded in the object can be adjusted according to needs, thereby achieving the effect of multi-directional connection.
