Description

The built-in ammeter box of door-hinge

Technical field

The utility model relates to a kind of ammeter box, exactly is the built-in ammeter box of a kind of door-hinge.

Background technology

The casing of existing ammeter box and the door-hinge of chamber door all are positioned at outside the casing, the user finds that in actual applications this structure ammeter box has the following disadvantages: 1, door-hinge is the weakest position on the whole ammeter box, more fragile than other positions, if door-hinge is positioned at outside the casing, be subjected to the extraneous probability of damaging high, make that the serviceable life of ammeter box is generally shorter, and, be positioned at the outer door-hinge of casing and easily destroyed by electricity filching person, anti-theft effect is relatively poor; 2, door-hinge is positioned at the outer ammeter box of casing, and its chamber door and casing are difficult for realizing sealing, and the ammeter in it is subject to the destruction of external environment, is difficult to guarantee that ammeter normally moves.

The utility model content

The purpose of this utility model has provided the built-in ammeter box of a kind of door-hinge, and it can solve the problem that prior art exists, long service life, and good anti-theft effect, and have the better seal effect.

The utility model is achieved through the following technical solutions: the built-in ammeter box of door-hinge, comprise casing and chamber door, inside casing with sealing function is installed on the inwall of casing, inside casing is the closed loop structure, a pair of door-hinge is installed on the inside casing, and door-hinge all is positioned at box inside, between the described a pair of door-hinge chamber door is installed, chamber door is hinged by door-hinge and casing, and chamber door and inside casing after the closure are sealed and matched.

For further realizing the purpose of this utility model realizing by the following technical solutions: described inside casing is to connect into closed square frame from beginning to end by two inside casing cross bars and two inside casing montants.Be provided with case internal fixation projection in the casing, case internal fixation projection is connected with inside casing by bolt.Inside casing is provided with axle bed in a pair of case, and axle bed connects one to one with door-hinge respectively in the case; Chamber door is provided with a pair of chamber door contiguous block, and chamber door contiguous block and door-hinge connect one to one.Backplate is set on the chamber door, and backplate is corresponding one by one with the chamber door contiguous block, and backplate is positioned at the outside of corresponding chamber door contiguous block.The inside casing flanging is set on the inside casing, the chamber door flanging is set on the chamber door, the inside casing flanging cooperates with the chamber door flanging.

Good effect of the present utility model is: its door-hinge is positioned at box inside, and casing can protect door-hinge not to be subjected to extraneous infringement effectively, makes electricity filching person be difficult to reach the purpose of opening the ammeter box stealing by destroying door-hinge simultaneously, and anti-theft effect is imitated.Box inside is equipped with dismountable inside casing, and inside casing can cooperate with chamber door and reaches the better seal effect, can protect ammeter in the casing not to be subjected to the influence of external environment effectively.And, because inside casing is that individual components can be made separately, therefore, can effectively reduces the integral production difficulty of ammeter box, thereby reduce production costs.The utility model also has compactness simple for structure, manufacturing process advantage simple, cheap for manufacturing cost.

Embodiment

The built-in ammeter box of door-hinge described in the utility model comprises casing 1 and chamber door 2, and the inside casing 3 with sealing function is installed on the inwall of casing 1, and shown in Figure 10 to 12, inside casing 3 is closed loop structures, so that can farthest guarantee sealing effectiveness.A pair of door-hinge 5 is installed on the inside casing 3, and door-hinge 5 all is positioned at casing 1 inboard, and chamber door 2 is installed between the described a pair of door-hinge 5, and chamber door 2 is hinged by door-hinge 5 and casing 1.Because door-hinge 5 is positioned at casing 1 inboard; the inevitable casing 1 that also is positioned in the position that chamber door 2 is connected with door-hinge 5; therefore; door-hinge 5 is hidden in casing 1 inside deeply; and by casing 1 and the protection of chamber door 2 double wrapped; both can avoid the infringement of external environment to door-hinge 5, and electricity filching person had been faced be wrapped in outer casing 1 of door-hinge 5 and chamber door 2 and had no way of doing it, anti-theft effect is better.Inside casing 3 can be to 2 position-limiting actions of chamber door, and inside casing 3 can be sealed and matched with the chamber door 2 after the closure simultaneously, and promptly above-mentioned sealing cooperates realization by chamber door 2 with inside casing 3.

Existing ammeter box is difficult to for a long time to realize that one of major reason of sealing is, the technology difficulty that one is made the casing 1 that is provided with inside casing 3 is too big, production cost is too high, make the casing 1 of ammeter box producer produces all not have inside casing 3, only cooperated with casing 1 by chamber door 2, its sealing effectiveness must satisfy user's request for utilization.For solving an above-mentioned difficult problem,, draw following scheme through to the screening of a large amount of design proposals and a large amount of actual production practices, as Fig. 3 and shown in Figure 5, be provided with case internal fixation projection 6 in the casing 1, case internal fixation projection 6 is connected with inside casing 3 by bolt, makes between inside casing 3 and the casing 1 dismounting freely.For strengthening the ability of case internal fixation projection 6 bearing loads, case internal fixation projection 6 should be connected with the bottom surface simultaneously with the sidewall of casing 1.

For further reducing the difficulty of processing of inside casing 3, reduce production costs, described inside casing 3 can connect into closed square frame from beginning to end by two inside casing cross bar 3-1 and two inside casing montant 3-2.Difference according to ammeter box chamber door quantity, can adopt more inside casing cross bar 3-1 and inside casing montant 3-2 to constitute inside casing with a plurality of closed frames, the quantity of closed frame is identical with the quantity of chamber door, shown in Figure 10 to 12, has two chamber doors 2 about two closed frame correspondences on the inside casing 3.

For chamber door 2 is embedded in the casing 1, so that 5 more hidden being difficult to of door-hinge are destroyed, shown in Fig. 6 to 9, inside casing 3 is provided with axle bed 4 in a pair of case, and axle bed 4 connects one to one with door-hinge 5 respectively in the case; Chamber door 2 is provided with a pair of chamber door contiguous block 7, and chamber door contiguous block 7 connects one to one with door-hinge 5.Chamber door 2 and casing 1 are hinged by axle bed 4 and door-hinge 5 in chamber door contiguous block 7, the case.

In order to protect door-hinge 5 not to be damaged better, shown in Fig. 6 to 9, backplate 9 is set on the chamber door 2, backplate 9 is corresponding one by one with chamber door contiguous block 7, and backplate 9 is positioned at the outside of corresponding chamber door contiguous block 7.Chamber door contiguous block 7 can block the junction of chamber door 2 and inside casing 3, can prevent that electricity filching person from being destroyed door-hinge 5 by the slit assistant of chamber door 2 with inside casing 3 junctions, can further improve anti-theft effect.

For further improving the sealing effectiveness of chamber door 2 and inside casing 3, as shown in Figure 3, inside casing flanging 8 is set on the inside casing 3, chamber door flanging 10 is set on the chamber door 2, inside casing flanging 8 cooperates with chamber door flanging 10.

The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology.
