Abstract
The utility model relates to a waterproof and zero adjusting mechanism for a table spring dial balance, comprising a balance shell body and a large frame. The waterproof and zero adjusting mechanism for a table spring dial balance is characterized in that A waterproof cover is arranged between the large frame and the balance shell body. The spacing A between the circumference of the large frame and the balance shell body is shielded by the waterproof cover, and a zero adjusting mechanism is arranged outside the waterproof cover. The structure of the waterproof and zero adjusting mechanism for a table spring dial balance is simple. After the structure is used, water can no longer enter the position of the large frame of a table spring dial balance. The waterproof performance of the table spring dial balance is enhanced, and the service life of the table spring dial balance is extended.
Description
The utility model relates to a kind of waterproof and zero adjuster of case formula spring scale scale.
Single face case formula spring balance is the Automatic balance that replaces lever scale, since promoting in the whole nation latter stage eighties, use type as shown in Figure 1 always, this type is provided with metering spring in big frame vertical plane, pointer, zero adjuster, because when weighing, big frame needs vertical up-or-down movement, and can not have external force to disturb, so, have the interval of 4-5mm around it and between the scale shell body, when the various hydrous matter of weighing, water flows directly in the casing like this, cause the corrosion of movement part, reduce the serviceable life of scale.
The purpose of this utility model is to provide a kind of waterproof and zero-bit adjusting mechanism of case formula spring scale scale, uses after this structure the big chord position of case formula spring scale scale to put no longer to have water to enter.
The purpose of this utility model is achieved in that
A kind of waterproof and zero-bit adjusting mechanism of case formula spring scale scale, comprise the scale housing, big frame is characterized in that being provided with one group of bucker between big frame and scale housing, bucker is covered the interval A between big frame peripheral and the scale housing, and is located at the zero-bit adjusting mechanism outside bucker.
The waterproof and the zero-bit adjusting mechanism of aforesaid a kind of case formula spring scale scale, it is characterized in that the zero-bit adjusting mechanism comprises the adjusting zero rod thick stick, the middle part of adjusting zero rod thick stick is fixed on the zeroing support by the steel axle, and can rotate around the steel axle, the zeroing support is welded on the scale housing, one end of zeroing lever is hung metering spring, and the other end is withstood by the zeroing screw that is rotated with on the zeroing support.
The waterproof and the zero-bit adjusting mechanism of aforesaid a kind of case formula spring scale scale, it is characterized in that bucker is made up of outer bucker and inner waterproofing cover, outer bucker is fixed on the big frame, and the inner waterproofing cover is fixed on the scale housing, and outer bucker is enclosed within outside the inner waterproofing cover.
The waterproof and the zero-bit adjusting mechanism of aforesaid a kind of case formula spring scale scale is characterized in that outer bucker can be to the cassette shapes of under shed, and the inner waterproofing cover can be corresponding with it cylindrical body.
The utility model is simple in structure, uses after this structure the big chord position of case formula spring scale scale to put no longer to have water to enter.Improve the water proofing property of scale, prolonged scale serviceable life.
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation:
Fig. 1 is the structural drawing of existing case formula spring scale scale
Fig. 2 is a structural representation of the present utility model
Fig. 3 is the local cut-away structure chart of the utility model A-A
Fig. 4 is the fundamental diagram of zeroing lever
The utility model comprises scale housing 1, big frame 2, between big frame 2 and scale housing 1, be provided with one group of bucker 3, bucker 3 with around the big frame 2 and the interval A between the scale housing 1 cover, bucker 3 is made up of outer bucker 4 and inner waterproofing cover 5, outer bucker 4 is fixed on the big frame 2, and inner waterproofing cover 5 is fixed on the scale housing 1, and outer bucker 4 is enclosed within outside the inner waterproofing cover 5.Like this, the water that flows down during weighing flows down along bucker 3, can not flow directly in the scale housing 1, and it can not influence the motion of big frame 2 again, has guaranteed the accuracy of weighing, has prolonged the serviceable life of scale.
Because bucker 3 is located at the gap location between big frame 2 and the scale housing 1, the residing position of former balancing controls has been positioned at the waterproof inner cover, can not return to zero, the zeroing nut must be moved out to outside the bucker, therefore, the utility model provides a cover new zero-bit adjusting mechanism, it comprises adjusting zero rod thick stick 6, the middle part of adjusting zero rod thick stick 6 is fixed on the zeroing support 8 by steel axle 7, and can rotate around steel axle 7, zeroing support 8 is welded on the scale housing 1, and an end of zeroing lever 6 is hung metering spring 9, and pressing with tower spring 10, the other end is withstood by the zeroing screw 11 that is rotated with on zeroing support 8.Zeroing screw 11 usefulness zeroing nut 14 covers, and anti-sealing flows into from the position of zeroing screw 11.Turn zeroing nut 14 produces displacement vertically, and zeroing lever 6 rotates around steel axle 7, drives metering spring 9 displacements, thereby reaches the requirement of pointer zero set.When the left end of zeroing lever 6 withstood outrigger F, this was a lower dead center, and the screw conical surface 12 on the right-hand member of zeroing lever 6 pastes mutually with spring bearer plate 13 peritremes, and this is a top dead centre.Thereby control zeroing scope is 16 calibration.Head on a tower spring 10 between spring bearer plate 13 and zeroing lever 6, it plays a part to make this cover mechanism to eliminate the gap, thereby makes weighing reach stable.
