Abstract
The utility model relates to a locking screw device for a box body. The locking screw device comprises a screw, a threaded hole A and a threaded hole B, wherein the threaded hole A and the threaded hole B are fitted with the screw. The threaded hole A is formed in a box cover, the threaded hole B is formed in a counter hole of a box body flange, the screw comprises a shaft portion and a head portion, a threaded section is formed at the end of the shaft portion, the shaft portion between the threaded section and the head portion is a polish rod, the diameter of the polish rod is smaller than the small diameter of the threaded section, a matched section is arranged in the counter hole between a surface where the box body flange is locked and contacted with the box cover and an upper end face of the threaded hole B, and the length of the matched section is larger than or equal to that of the threaded section. The locking screw device for the box body enables a user to easily distinguish whether the screw breaks away from a nut or not, the screw can still stay on the box cover after the box cover is opened, the screw cannot easily fall off, and the locking screw device brings convenience to installation and maintenance by an operator and improves disassembly and assembly efficiency.
Description
Technical field
The utility model relates to the communications equipment technical field, more particularly, relates to a kind of lock screw device that is used for fixing case lid and housing seat.
Background technique
Along with constantly popularizing of network and pushing forward comprehensively of FTTx networking, polymer casing particularly optical cable fiber-dividing box is used widely, and the lock screw of casing is also corresponding to be used widely.But at present, the lock screw structure of using on casing is more coarse simple, and screw thread length is longer, and nut is positioned at the position of fitting with case lid on the housing seat.During the case lid breakdown, turn screw and break away from nut, then the tapped hole of stationary conduit has produced to connect and has cooperated on screw and the case lid, and at this moment, the operator takes for screw and also do not back-out from nut, continues to unscrew operation, very easily screw is come off from case lid is stubborn.So the phenomenon on toner screw one ground after regular meeting occurs opening case lid brings great inconvenience for operations such as subsequent installation, maintenance.
The model utility content
The technical problems to be solved in the utility model is, overcomes the prior art defective, provides a kind of screw of easily distinguishing whether to break away from nut, and screw still places lock screw device on the case lid behind the case lid breakdown.
The technological scheme that its technical problem that solves the utility model adopts is: construct a kind of lock screw device that is used for casing, comprise that screw reaches and suitable tapped hole A and the tapped hole B of this screw, tapped hole A is arranged on the case lid, tapped hole B is arranged in the counterbore of box flange, screw comprises axial region and head, the axial region termination is provided with thread section, axial region between this thread section and head is a polished rod, the diameter of this polished rod is less than the path of thread section, box flange is provided with the cooperation section with the counterbore that case lid is locked between surface to the upper-end surface of tapped hole B that contacts, and the length of this cooperation section is not less than the length of thread section.
Be used for the lock screw device of casing at the utility model, also comprise nut, nut is arranged in the counterbore of box flange, and tapped hole B is arranged on the nut.
Be used for the lock screw device of casing at the utility model, also comprise nut, nut is arranged on the case lid, and tapped hole A is arranged on the nut.
Implement the lock screw device that the utility model is used for casing, compared with the prior art, its beneficial effect is: the lock screw device that the utility model is used for casing can easily pick out screw and whether break away from tapped hole B, and screw still places on the case lid behind the case lid breakdown, difficult drop-off, easy-to-operat person I﹠M has improved dismounting efficient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the screw lock view that the utility model is used for the lock screw device of casing.
Fig. 2 is that the screw that the utility model is used for the lock screw device of casing is unscrewed view.
Fig. 3 is the generalized section of Fig. 1.
Fig. 4 is the application schematic representation that the utility model is used for the lock screw device of casing.
Embodiment
As shown in Figures 1 to 4, the utility model is used for the lock screw device of casing, comprise screw 10 and with suitable tapped hole A21 and the tapped hole B311 of this screw 10, tapped hole A21 is arranged on the case lid 20, tapped hole B311 is arranged in the counterbore 31 of box flange 30, screw 10 comprises axial region 11 and head 12, axial region 11 terminations are provided with thread section 111, the axial region 11 that this thread section 111 and head are 12 is polished rods 112, the diameter of this polished rod 112 is less than the path of thread section 111, box flange 30 is provided with cooperation section 312 with the counterbore 31 that case lid 20 is locked between surface 32 to the upper-end surface of tapped hole B311 that contacts, and the length of this cooperation section 312 is not less than the length of thread section 111.
Also comprise nut 40, nut 40 is arranged in the counterbore 31 of box flange 30, and tapped hole B311 is arranged on the nut 40.Be that tapped hole B311 can be set directly in the counterbore 31 of box flange 30; Also can be arranged on the nut 40, and nut 40 places in the counterbore 31 of box flange 30.Tapped hole A can be set directly on the case lid; Also can be arranged on the nut, and nut places on the case lid.
In the present embodiment, tapped hole B311 is arranged on the nut 40, operating process is as follows: when carrying out the operation of case lid 20 breakdowns, unscrew screw 10, move on the thread section 111, break away from fully until screw 10 and nut 40, at this moment, oscillating screw 10 heads, based on the diameter of polished rod 112 path less than thread section 111, the operator can feel that fully screw 10 unscrewed and break away from nut 40.Simultaneously, the tapped hole A21 on the case lid 20 also can block screw 10, prevents that effectively screw 10 from coming off.So behind the breakdown case lid 20, screw 10 still places on the case lid 20, can not come off.
Above embodiment has been described in detail the utility model, and formation is to restriction of the present utility model but these are not.Protection domain of the present utility model does not exceed with above-mentioned mode of execution, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
