Description
Technical field
The invention belongs to be machined spare and accessory parts field, and in particular to a kind of detachable bolt.
Background technology
Bolt is machine components, the cylindrical threaded fastener of adapted nut.By bolt head and screw rod（With outer spiral shell
The cylinder of line）Class fastener dimerous, need to coordinate with nut or screwed hole, i.e., for being fastenedly connected two bands
There is the part of through hole.
All offer flat recess or cross recess on most bolt head in the market, then by the flat recess or
It is that cross recess utilizes instrument（Straight screwdriver or Phillips screwdriver）It is turned and unscrews or tighten.But many situations
Under, due to this province structural strength problem of bolt, or bolt by being used for a long time caused by bolt just enough intensity step-down,
Screwdriver is caused to coordinate in flat recess or cross recess during rotating bolt, the cell wall of flat recess or cross recess is deteriorated,
So as to cause bolt can not be rotated by screwdriver；Meanwhile, many times, people can't carry with the work to rotating bolt
Tool, or the instrument carried with are not adapted to the bolt to be rotated, therefore can be to wanting some to be badly in need of the people of rotating bolt
Worry can be brought.Therefore traditional bolt has improved place.
Bolt generally coordinates with the screwed hole on nut or machine to be played a part of being connected fastening parts, is using bolt
When progress locks parts, typically first to put and lock parts after spring washer again, by the elastic force of spring washer
To increase the frictional force of the screw thread on bolt, and then to prevent the loosening of bolt, although this method can be very good to play spiral shell
The locking effect of bolt, but so use and just compare, it is necessary to first to cover spring washer on bolt before bolt is screwed on
Trouble.
Meanwhile, when bolt head or screw rod damage, whole bolt overall must just be scrapped, and wastage is excessive.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to which the existing one kind that provides can be prevented without using spring washer
Loosen, a variety of screwdriver heads suitable for a word bottle opener and cross driver, opened without bottle opener while in emergency circumstances can also realize
Open, avoid the overall detachable bolt scrapped.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of detachable bolt, its innovative point exists
In：Including screw rod and bolt head, the bolt head is provided with multiple elastic pressuring plates, the elasticity in the end face side being connected with screw rod
Tabletting includes fixing end and free end, and the multiple elastic pressuring plate is fixedly connected with bolt head by fixing end and is in around screw rod
Annular arrangement, the side end of the bolt head is further opened with a swivelling chute, and the screw rod is passed through inside and outside by the end of thread and polished end
Threaded connection is formed.
Further, the upper end center position of the bolt head offers a cruciform groove, the bolt head
The depth of the swivelling chute of side end is 0.4-0.8cm, a diameter of 0.2-0.4cm of the swivelling chute.
Further, the screw rod upper surface offers rotation screw thread, and the spacing between the adjacent rotation screw thread is
0.2-0.5cm。
Further, the multiple elastic pressuring plate is uniformly arranged in umbrella frame shape around screw rod, the bolt head connection elasticity
The side of tabletting is further opened with a circular groove.
Beneficial effects of the present invention are as follows：
（1）The present invention may be such that elastic pressuring plate is compressed into circular groove after elastic pressuring plate is extruded deformation, keep spiral shell
The end face that bolt head is connected with screw rod fits with connected body surface, the compactness of lifting product connection.
（2）The present invention in the side end of bolt head by offering a swivelling chute, in the case of band instrument is forgotten, as long as choosing
The similar cylinder rod of diameter is selected, is applied in swivelling chute, the loosening or fastening of bolt is realized, substantially increases operating personnel
Convenient degree.
（3）The present invention can be applied to yi word pattern bottle opener and ten simultaneously by offering cross recess in bolt head upper end
Font bottle opener, the scope of application is big.
（4）The screw rod of the present invention realizes detachable connection by the end of thread and polished end by internal and external threads, bolt head or
Any one is damaged in person's screw rod, it is possible to achieve the replacing of half dismounting, greatly reduces the damaged waste caused.
Brief description of the drawings
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is top view of the invention.
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
As depicted in figs. 1 and 2, a kind of detachable bolt, including screw rod 1 and bolt head 2, bolt head 2 connect with screw rod 1
The end face side connect is provided with multiple elastic pressuring plates 3, and elastic pressuring plate 3 includes fixing end and free end, and multiple elastic pressuring plates 3 pass through
Fixing end is fixedly connected with bolt head 2 and arranged in a ring around screw rod 1, and the side end of bolt head 2 is further opened with a swivelling chute 4,
