Abstract
The utility model discloses a double -threaded screw, including the body of rod, screw thread and screw terminal, the screw terminal includes main screw terminal and follows the screw terminal, sets up respectively at the both ends of the body of rod, the screw thread sets up at main screw terminal with from between the screw terminal, the utility model discloses double -threaded screw can be never equidirectional with screw loosening, convenient follow -up maintenance to the device, reduction maintenance cost.
Description
Technical field
The utility model relates to a kind of screw, particularly relates to a kind of double-threaded screw.
Background technique
Screw is seen everywhere in existing production and life as a kind of connection set.Along with the difference of application, current screw kind is on the market also very various, but modal non-single threaded screw, this screw is made up of threaded body and screw terminal, need owing to installing, screw terminal can be arranged cross recess or straight groove or interior hexagonal groove and outer six face structures.But this screw only has one side screw can be unscrewed after installing, gear, when needs are safeguarded, will need the service portion that do not need before service portion also to remove by the module that some are screwed and casing, inconvenience very, or the space of maintenance is less, cannot safeguard.
Model utility content
Main purpose of the present utility model is to provide a kind of double-threaded screw, is intended to unscrew screw from different directions.
For achieving the above object, the utility model provides a kind of double-threaded screw, comprises the body of rod, screw thread and screw terminal, and described screw terminal comprises main screw terminal and from screw terminal, is separately positioned on the two ends of the body of rod, and described screw thread is arranged on main screw terminal and between screw terminal.
Preferably, the described external diameter being less than screw thread from screw terminal.
Preferably, the external diameter of described screw thread is not less than the diameter of the body of rod.
Preferably, described main screw terminal is greater than the external diameter of screw thread.
Preferably, described main screw terminal is provided with cross recess or straight groove or interior hexagonal groove.
Preferably, also rubber cushion is provided with bottom described main screw terminal.
Preferably, described screw thread is close to and arranges from screw terminal.
Preferably, described from screw terminal be outer-hexagonal structure.
Preferably, the described body of rod is cylindrical.
Screw can unscrew by the utility model double-threaded screw from different directions, and the convenient subsequent maintenance to device, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is the front elevation of the utility model double-threaded screw one embodiment;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is the perspective view of Fig. 1;
Description of reference numerals: 1 is main screw terminal, 2 is from screw terminal, and 3 is the body of rod, and 4 is screw thread, and 5 is rubber cushion.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of double-threaded screw, with reference to Fig. 1-4, in one embodiment, described double-threaded screw, comprises the body of rod, screw thread and screw terminal, and described screw terminal comprises main screw terminal and from screw terminal, be separately positioned on the two ends of the body of rod, described screw thread is arranged on main screw terminal and between screw terminal.
Screw can unscrew by the present embodiment double-threaded screw from different directions, the convenient subsequent maintenance to device; Such as, when screen being safeguarded, or out of order module can be pulled down below keep in repair from front, so just can select direction rotary screw for convenience detach, reduce maintenance cost.
Described screw thread is close to and arranges from screw terminal, the external diameter of described screw thread be greater than the body of rod diameter and from screw terminal, described main screw terminal is greater than the external diameter of screw thread, and described main screw terminal is provided with cross recess or straight groove or interior hexagonal groove; Described from screw terminal be outer-hexagonal structure, or, be describedly provided with cross recess or straight groove or interior hexagonal groove from screw terminal; Also be provided with rubber cushion bottom described main screw terminal, the hardness of described rubber cushion more than 80, and adopts anti-aging material; The described body of rod is cylindrical.During use, if when module will be fixed on casing, above-mentioned main screw terminal can block module, simultaneously because main screw terminal is larger, arrange groove to rotate and more not easily skid, less then should not adopt groove to rotate from screw terminal, above-mentioned rubber cushion can play waterproof action, above-mentioned screw terminal all adopts NBS, and the diameter of main screw terminal is 6mm, and the diameter of the body of rod is 2.9mm, in screw terminal, circular diameter is 2.5mm, the length of screw thread is 10mm, is 15mm from the length of screw terminal, and the length of double-threaded screw is 52.5mm.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
