Abstract
The invention relates to a sliding weight retractable steelyard. The sliding weight retractable steelyard is characterized in that the steelyard is composed of hollow sleeve pipes (1, 2, 3 and 4) with scales, a weighbeam is retractable, a sliding weight (6) is arranged on the weighbeam and sleeves the hollow sleeve pipes to slide, a window (6b) and a pointer (6a) are disposed on the sliding weight, and scale values can be observed through the window and the pointer. The sliding weight retractable steelyard has the advantages that the weighbeam is freely retractable, length of the weighbeam during carrying is greatly reduced so that the steelyard is extremely convenient to carry about, and the steelyard is not prone to break off and bend. Besides, the sliding weight can freely slide on the weighbeam, the disassembly is convenient, and weighing is accurate.
Description
Technical field:
The invention relates to the weighing apparatus in weighing apparatus, specifically a kind of steelyard of weighing weight of object.
Background technology:
In weighing apparatus below current 50 Kg load, the most frequently usedly on market remain steelyard.But traditional steelyard is rigid thin rod, is mostly wooden or aluminium matter.Because the arm beam of steelyard is longer, length immobilizes again, and sliding weight of steelyard hangs on the arm beam of steelyard, thus uses and carries extremely inconvenient, and frangibility or touch curved.
Innovation and creation content:
The invention object is the above-mentioned shortcoming that will overcome existing steelyard, provides a kind of length of the arm beam of steelyard freely to change, and claims stone roller can slide on the arm beam of steelyard, sliding stone roller contracting steelyard easy to use and easy to carry.
The invention achieves the above object by following technical solution:
Sliding stone roller contracting steelyard, the suspension hook comprising the arm beam of steelyard and be connected on the arm beam of steelyard and rope, it is characterized in that: the hollow bushing diminished successively by one group of at least two diameter forms, two adjacent hollow bushings are formed and can be set with flexible clearance fit, each hollow bushing inside is provided with elastic steel ball locating device, each hollow bushing is provided with scale, when each hollow bushing is all stretched out, forms a complete arm beam of steelyard.
On the basis of above-mentioned basic technical scheme, arrange coordinate with the arm beam of steelyard sliding to cut or polish jade with an emery wheel, sliding stone roller middle part is provided with through hole, art skating on the arm beam of steelyard can be enclosed within, be provided with the pre-tightening apparatus of spring, fore-set composition in sliding stone roller, when sliding stone roller is slided on waney arm beam of steelyard, spring preloading device withstands the arm beam of steelyard, anti-on-slip stone roller produces when weighing and slides, and affects weighing accuracy.Be provided with a form in sliding stone roller side to communicate with this through hole, form is provided with pointer scale and coordinates with the scale on the arm beam of steelyard, is convenient to weigh.
The length of hollow bushing pull-out is by steel ball restriction, and steel ball and spring load in the endoporus of hollow bushing one end, and when two adjacent joint hollow bushings move the position of needs to, steel ball ejects, and is stuck in groove, by steel ball location, constant to ensure arm beam of steelyard total length.
The joint number of hollow bushing is determined according to the size of range of weighing.Hollow bushing head joint and each joint hollow bushing are the metal tubes that external diameter reduces successively, mutually can be inserted in successively and can do longitudinally to pull.The outside surface of each joint hollow bushing all passes through process, and scale adopts high-frequency percussion to form.
The invention advantage is: arm beam of steelyard retractable, and greatly shorten the length of arm beam of steelyard when carrying, it is very convenient thus to carry, and not frangibility and touch curved.Sliding stone roller can on bar art skating, convenient disassembly, weighs accurately.
Accompanying drawing illustrates:
Fig. 1 is the invention structural representation;
Fig. 2 is the invention B portion amplification profile;
Fig. 3 is the invention A-A sectional view.
Wherein: 1-head joint hollow bushing; 2-hollow bushing; 3-hollow bushing; 4-hollow bushing; 5-graduated scale; The sliding stone roller of 6-; 6a-pointer; 6b-form; 6c-fore-set; 6e-spring; 6f-screw; 7-suspension hook; 8-rope; 9-steel ball; 10-spring.
Embodiment:
Embodiment 1: for four poles, the invention is further illustrated below in conjunction with accompanying drawing.
Refer to Fig. 1, hollow bushing 1, hollow bushing 2, hollow bushing 3, hollow bushing 4, sliding stone roller 6, suspension hook 7 and rope 8 form the primary structure of the invention.Hollow bushing 4 can be inserted in hollow bushing 3, and can be inserted in successively in first joint hollow bushing 1, and it connects for clearance fit.Suspension hook 7 is riveted on first joint hollow bushing 1 lower surface.Rope 8 is connected to first joint hollow bushing 1 upper surface.Sliding stone roller 6 is enclosed within hollow bushing, can on each joint hollow bushing art skating, sliding stone roller 6 be provided with form 6b and pointer 6a and, during weighing, be convenient to observe scale.
Refer to Fig. 2, steel ball 9 is connected to the two ends of spring 10, save hollow bushing 1 and hollow bushing 2 all has by carrying knob one end the groove matched with steel ball 9 at head, steel ball 9 and spring 10 loaded in hollow bushing 2, when hollow bushing 2 to save in hollow bushing 1 from head be pulled out to need position time.Two ends steel ball ejects, and is stuck in groove inner position, ensures that pull-out length is fixed.Other a few joint hollow bushing joints situation is identical therewith.
Refer to Fig. 1, Fig. 3, be provided with the through hole, the side that coordinate with hollow bushing in the middle part of sliding stone roller 6 and be provided with form 6b and communicate with through hole, form 6b is provided with the pointer scale 6a matched with the scale 5 on hollow bushing.Scale can be observed at any time when sliding stone roller slides, be convenient to weigh.
In addition, spring 6e is installed in the hole of sliding stone roller 6 lower end, is fixed by screw 6f, and the upper end of spring 6e arranges a fore-set 6c and coordinates with front casing joint, and they form spring preloading device.Being inserted in by hollow bushing in sliding stone roller 6, sliding stone roller 6 is when the hollow bushing bar becoming radius slides, and corresponding spring 6e is forced through fore-set, and anti-on-slip stone roller rocks, and affects weighing precision.
