Description
Technical field
The present invention relates to spring product technical field more particularly to a kind of spring weighing devices.
Background technique
Spring scale is called weight beam, is acted on using measurement made of the deformation of the spring relationship directly proportional to external force
The device of power size.Spring scale partial pressure and pulling force two types, the pressure that the pallet of pressure spring balance is born are equal to object
Gravity, the numerical value of the angle instruction pressure of scale pan pointer rotation.The lower end of tension spring scale and a hook connect together
(this hook is connected together with lower spring end), the upper end of spring is fixed on the ring on shell top.Measured object is hung on hook,
Spring extends, and is fixed on the pointer on spring with decline.Due in elastic limit, the elongation of spring and it is suffered except
Power is directly proportional, therefore the size of active force or object gravity can be direct from the scale numerical value on the shell that the pointer of spring scale indicates
It reads.Existing spring balance dismounts inconvenience mostly, and structure is not secured enough, easy to damage.
Summary of the invention
Technical problems to be solved
The problem to be solved in the present invention is to provide a kind of spring weighing devices, to overcome dismounting in the prior art inconvenient, and
And structure is not secured enough, defect easy to damage.
Technical solution
To solve the technical problem, the present invention provides a kind of spring weighing device, including main casing, spring, support rod,
Hook, positioning plate, end cap and spring cushion block；The post upper is directly plugged and fixed with the positioning plate, and lower end grafting is solid
The fixed hook；Several described spring cushion block clampings are arranged in the main casing inner bottom；The spring cushion block with it is described
Support rod is mating；The support rod is socketed in the central through hole of the spring；The post upper and the positioning
Plate is in contact, and lower end is in contact with the spring cushion block；The spring, support rod, hook and positioning plate are arranged at the master
In enclosure interior cavity；The end cap is fixed with the main casing, and the spring, support rod, hook and positioning plate is completely solid
It lives calmly；The through-hole phase clearance fit in the arrow portion of the positioning plate and the end cap.
Preferably, scale is provided on the panel of the end cap.
Preferably, the location hole mating with the support rod is provided on the spring cushion block.
Preferably, the spring cushion block is seven pieces.
Preferably, pull ring is additionally provided at the top of the main casing.
Having the beneficial effect that spring weighing device of the invention, structure is simple, very convenient, more setting spring cushion blocks are dismounted,
Sound construction greatly increases, and is hardly damaged.
Detailed description of the invention
