Abstract
The utility model provides a secondary protector for a spring arm, which comprises a spring arm, a spring arm connecting shaft, a groove arranged on the spring arm connecting shaft, a clamping sheet corresponding to the groove and a jacket sheathed on the spring arm connecting shaft, wherein the spring arm connecting shaft is provided with a connecting through hole for secondary protection, inner hexagonal cylinder-head screws are respectively arranged at two ends of the through hole, and the specification of the inner hexagonal cylinder-head screws is as follows: the diameter is 4 millimeters, and the length is 6 millimeters. The secondary protector for the spring arm has the following technical effects: (1) the structure is completed on the basis of the original product, and has high compatibility and low additional cost; (2) by using the structure, the risk of the spring arm is greatly reduced, thus protecting operators and relevant staffs; and (3) the structure has simple principle, is convenient to install, is safe and reliable, and has wide application range.
Description
Technical field
This utility model relates to a kind of spring arm device that is used to hang on the armarium, specifically, relates to a kind of second protection device of spring arm, belongs to the armarium technical field.
Background technology
In operating room; be used to hang that operating lamp and the equilibrated hitch of miscellaneous equipment needs generally adopt is the spring arm device; the working method of common in the market spring arm device is roughly the same; when common spring arm device used, protection lead shield or operating lamp and similar equipment were not drop by card connection and protection equipment.As shown in Figure 1, 2, the spring arm device comprises spring arm 1, spring arm connecting axle, be located at groove on the spring arm connecting axle, with the corresponding card of groove be enclosed within sheath 4 on the spring arm connecting axle, shown in Fig. 3,4, also be provided with on the connecting axle of armarium lead shield assembly 6 or lamp adapter assembly 7 and card 2 corresponding grooves, during installation, the connecting axle of armarium is stretched in the connecting axle of spring arm, connect and fix by card 2, on the connecting axle of spring arm, be inserted in sheath 4 and pass through countersunk head screw 5 lockings.Wherein sheath 4 is used for preventing that card 2 from dropping.Yet equipment such as protection lead shield and operating lamp generally are to need rotation to use in the use of reality, behind operating lamp or lead shield life-time service, card can produce wearing and tearing, and shearing force suffered on the card may cause its fracture, cause serious malpractice, even life danger.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of second protection device of spring arm is provided.
The second protection device of spring arm of the present utility model; comprise spring arm, spring arm connecting axle, be located at groove on the spring arm connecting axle, with the corresponding card of groove be enclosed within sheath on the spring arm connecting axle; the spring arm connecting axle is provided with the connecting through hole of second protection; the through hole two ends are inserted with interior hexagonal socket cap screw respectively, and the specification of said interior hexagonal socket cap screw is M4 * 6.
Preferably,
Said spring arm connecting axle is provided with the caution circle.
The utlity model has following technique effect:
1) this structure is to transform to finish on the basis of existing product, and compatibility is very strong, and surcharge is low;
2) use of this structure can reduce the risk of spring arm greatly, protection operator and relevant personal security;
3) this structural principle is simple, and is easy for installation, safe and reliable, applied widely.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1, Fig. 2 are the structure explosive view of background technology medi-spring arm;
Fig. 3 is the installation diagram of background technology medi-spring arm;
Fig. 4 is that the A of Fig. 3 is to profile;
Fig. 5, Fig. 6 are the structure explosive view of spring arm of the present utility model;
Fig. 7 is the installation diagram of spring arm of the present utility model;
Fig. 8 is that the A of Fig. 7 is to profile;
Fig. 9 is a spring arm caution coil structures sketch map of the present utility model;
Wherein, 1 is spring arm, and 2 is card, and 3 is interior hexagonal socket cap screw, and 4 is sheath, and 5 is countersunk head screw, and 6 is the lead shield assembly, and 7 is lamp adapter assembly, and 8 are the caution circle.
The specific embodiment
Shown in Fig. 5,6; the second protection device of spring arm of the present utility model; comprise spring arm 1, spring arm connecting axle, be located at groove on the spring arm connecting axle, with the corresponding card 2 of groove be enclosed within sheath 4 on the spring arm connecting axle; the spring arm connecting axle is provided with the connecting through hole of second protection; the through hole two ends are inserted with interior hexagonal socket cap screw 3 respectively; the specification of hexagonal socket cap screw 3 is M4 * 6 in said, and as shown in Figure 9, the spring arm connecting axle is provided with caution circle 8.
During use, the connecting axle of armarium stretches in the connecting axle of spring arm, connects and fixes by card 2, is inserted in sheath 4 and passes through countersunk head screw 5 lockings on the connecting axle of spring arm.Shown in Fig. 7,8; on the connecting axle of the armarium that is hung on the spring arm; except having and the corresponding groove of card; also have and interior hexagonal socket cap screw 3 corresponding grooves; when card 2 is ineffective; the connecting axle of armarium can supported by the interior hexagonal socket cap screw 3 of second protection, all do not drop, a landing limited distance.Therefore; the spring arm that second protection has been arranged is when normal the use; if in case the card fracture failure takes place; the second protection screw can play the effect of protection; after dropping, equipment such as lead shield and operating lamp have simultaneously the caution color to manifest; the information that alert is relevant stops further operation, thereby avoids dangerous.
