Abstract
The invention relates to a bolt with anti-disassembly and locking functions, wherein thread parts are formed on the bar surfaces of both ends of a member bar respectively; and locking plastics and anti-disassembly glue which can provide different bonding forces are coated on the thread parts of both ends of the member bar respectively, so that one end coated with the anti-disassembly glue has strong bonding force after being combined with a corresponding bonding part and is difficult to disassemble, and the other end coated with the locking plastics can still be disassembled after being combined with a corresponding bonding part and has certain locking effect; therefore, the bolt can be applied to different positions between the bonding parts in a fitting way.
Description
Technical field
The present invention refers in particular on an end spiro tooth part and is coated with locking plastics, and be coated with tamper glue on the other end spiro tooth part about a kind of stud bolt, makes it have the bolt for combining person of tamper and locking functions.
Background technique
Stud bolt is a kind of of screw, it is formed with spiro tooth part respectively on the pole face of the two ends of a rod member, decide two ends on demand and can be identical or different thread, stud bolt generally is mainly used in conjunction with relatively large workpiece or part, the occasion that general bolt can't be suitable for, perhaps be used to connect a pedestal and a part, and this part has the demand of frequent dismounting, for avoiding causing the thread abrasion of pedestal end because of regular dismounting, stud bolt one end is just no longer dismantled after being installed in pedestal, the other end cooperates nut in order to fix this part, the use embodiment of stud bolt, for example be used in the engine, binding about cylinder block and cylinder head, be stamped demand such as maintenance owing to cylinder and need dismounting, as bolt comes in conjunction with cylinder block and cylinder head using, under regular dismounting, may cause the thread wearing and tearing even the damage of cylinder block screw, compared to the spiro tooth part of bolt once wearing and tearing or damage the convenience that can change immediately, the thread of the screw of cylinder block is difficult to repair or change, therefore generally can adopt stud bolt, make the one end be incorporated into cylinder block, and no longer dismounting.
Yet because stud bolt all is formed with spiro tooth part in two ends, its not an end of desire dismounting be incorporated into pedestal, and when the other end desire is locked or unclamped the nut of its combination, the strength that applies can drive bolt simultaneously and rotate, may cause an end of the dismounting of desire not thereby loosening, in addition, the vibrations that can produce suitable amplitude during engine running itself, therefore be used in each screw of engine, bolt, the locking of all necessary appropriateness such as nut, especially in order to stud bolt and nut in conjunction with cylinder head and cylinder block, once getting loose, nut may cause danger, therefore it must have suitable adhesive strength, therefore this nut place often has been used lock washer etc., however packing ring when the dismounting screw, lose easily, and the use of packing ring can increase the thickness and the weight of assembly.
Summary of the invention
Because the deficiency point and the user demand of above-mentioned existing stud bolt, the present invention is by being coated with locking plastics respectively in two terminal screw portions of stud bolt, and makes it have the function of locking and tamper.
For reaching the foregoing invention purpose, technological means used in the present invention is to provide the bolt of a kind of tool tamper and locking functions, it is a rod member, and on the pole face of two ends, be formed with spiro tooth part respectively, be coated with locking plastics and tamper glue on the spiro tooth part at two ends respectively, these locking plastics and tamper glue can use the U.S. respectively again
Company
Patch plastics and German omniTechnik company
80 colloids.
The invention has the advantages that, coat the locking plastics on the bolt one end spiro tooth part, can increase the combination force between itself and screw and the nut, can make bolt not an end of desire dismounting after combination, be and be difficult for disassembled configuration, and scribble the other end spiro tooth part of the bolt of locking plastics, its with relative conjunction between still be detachable, but after combination, can have suitable anti-loosing effect, this technological means can cooperate the position that is used in different demands between conjunction.
Description of drawings
Fig. 1 is a stereo appearance figure of the present invention;
Fig. 2 is that the present invention is in order to the enforcement view in conjunction with two members.
Embodiment
Referring to shown in Figure 1, the bolt of tool tamper of the present invention and locking functions is a rod member 10, and on the pole face at its two ends, be formed with spiro tooth part 11,12 respectively, these spiro tooth part 11,12 visual demands and form various teeth apart from or hand of spiral, on the spiro tooth part 11,12 at two ends, and be coated with locking plastics and tamper glue respectively, these locking plastics and tamper glue can be in spiro tooth part 11,12 and relative conjunctions, for example after the combination such as screw or nut, increase its combination force each other, wherein, the available combination force of this tamper glue is greater than these locking plastics;
Aforesaid locking plastics and the tamper glue of coating two ends spiro tooth part 11,12 can use the U.S. respectively
Company
Patch plastics and German omniTechnik company
80 colloids.
Further referring to shown in Figure 2, for the present invention cooperates a nut 22 in order to the schematic representation in conjunction with a pedestal 20 and a workpiece 21, wherein, the spiro tooth part 12 that is coated with tamper glue is incorporated on the pedestal 20 on the formed screw, and the spiro tooth part 11 that scribbles locking plastics combines with nut 22, and pedestal 20 and workpiece 21 are mutually combined, the invention has the advantages that, can provide strong and tamper glue effective combination force because spiro tooth part 12 scribbles, therefore this end can be quite firm, and the conjunction relative with screw etc. mutually combine and as the fixed end of desire dismounting not, therefore even will be incorporated in the bolt as the conjunction locking of the spiro tooth part 11 of detachable end or unclamp, also be difficult for causing the fixed end of bolt thereby becoming flexible, in addition, because on the spiro tooth part 11 as detachable end in bolt, other is coated with the locking plastics that can increase combination force, though make between this end conjunction relative to detachable with nut 22 grades, but in conjunction with after can have and prevent the effect become flexible, and the use of desirable advance (shenglvehao)for another circle.
