Abstract
The utility model discloses a combined adjustable weight which comprises a weight head (1) and a weight body (6), wherein a hollow cavity chamber (8) is arranged in the weight body (6); a metal counterbalancing block (7) is arranged in the hollow cavity chamber (8); internal screw threads (5) are formed at an upper opening of the hollow cavity chamber (8); external screw threads (4) are formed at the lower part of the weight head (1); the weight head (1) is fixed on the weight body (6) through the matching of the external screw threads (4) and the internal screw threads (5); a pressing ring (3) for pressing the upper end surface of the weight body (6) is arranged on the weight head (1); and a connecting neck (2) is arranged on the weight head (1). After the structure is adopted, the combined adjustable weight has the advantages of simple and reasonable structure, high measurement precision, quick counterbalancing and correction, good anticorrosion performance, long service life, and the like, and is convenient to process and manufacture.
Description
Technical field
The utility model relates to a kind of measurement instrument, particularly a kind of counterweight of weighing on balance or the balance weighing apparatus of being used for.
Background technology
As everyone knows, counterweight is the quality standard of balance or balance weighing apparatus Measuring Object, is used for weighing quality more accurately, mainly forms with made such as metallic copper, iron.Have measuring accuracy height, simple operation and other advantages when weighing, but in use have the following disadvantages with counterweight:
The one, after long-time the use, counterweight weares and teares easily, causes its weight saving, and its measuring accuracy is descended, and proofreaies and correct owing to can't carry out counterweight, when exceeding accuracy requirement, can only demote and use or scrap processing.
The 2nd, when under relatively poor environment, using balance or balance weighing apparatus to measure, perhaps after the long storage time, counterweight can be subjected to air corrosion, the copper counterweight can become rusty by the pig copper, and the iron counterweight can become rusty by the pig iron, causes its weight to increase, its measuring accuracy is descended, proofread and correct owing to can't carry out counterweight, when exceeding accuracy requirement, can only demote and use or scrap processing.Handle though can carry out coating, also firm inadequately, the coating phenomenon that comes off or get rusty appears sometimes, because the coating thickness has deviation, more difficult control counterweight quality behind the coating.
Therefore developing a kind of counterweight that neither can get rusty and can proofread and correct is present urgent problem.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not find reasonably solution so far as yet.
Summary of the invention
For overcoming the problems referred to above that existing counterweight exists, the purpose of this utility model provides the adjustable counterweight of combined type that a kind of simple and reasonable, non-corrosive, precision height, quality can be proofreaied and correct.
The technical scheme that its technical matters that solves the utility model adopts, it comprises counterweight head, counterweight body, be provided with hollow chamber in the described counterweight body, be provided with the metal weights piece in the hollow chamber, the internal thread that is provided with suitable for reading of hollow chamber, the bottom of counterweight head is provided with external thread, and the counterweight head was fixed on the counterweight body by external thread and cooperating of internal thread.
In order to prevent that dust from entering from hickey in the hollow chamber of counterweight body, improve the sealing of hollow chamber, reduce the counterweight precision, described counterweight head is provided with the compacting ring that compresses counterweight body upper surface.
In order to extract conveniently, described counterweight head is provided with the connection neck.
Can prevent that in order to ensure counterweight burn into is anti-oxidant, described counterweight head and counterweight body are made by wear-resisting, heatproof, ageing-resistant fluoroplastic, as materials such as teflon.
Counterweight counterweight, correction for convenience, and the counterweight that volume and metal material are made is close, described metal weights piece is processed by metallic copper.
After adopting said structure, the utility model compared with prior art has following advantage:
The one, counterweight head and counterweight body are left by the fluoroplastic split and process, so the anti-oxidant and Corrosion Protection of counterweight is good, and processing and manufacturing is also very convenient.
The 2nd, because counterweight head and counterweight body be assembled, configuration metal weights piece hollow chamber in, so counterweight, correction fast, the counterweight precision height that dispatches from the factory.
The 3rd, after the counterweight wearing and tearing, counterweight is very convenient again, and the counterweight precision is unaffected, can use long service life repeatedly.
The 4th, the counterweight head is provided with the compacting ring that compresses counterweight body upper surface, hollow chamber's good seal performance, and the metal weights piece can not produce oxidation and rusting, and precision height during use keeps the precision time long.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 counterweight head wherein, 2 connect necks, 3 compacting rings, 4 external threads, 5 internal threads, 6 counterweight bodies, 7 metal weights pieces, 8 hollow chamber.
Embodiment
Shown in Figure 1, specific embodiments for the adjustable counterweight of a kind of combined type of the utility model, it comprises counterweight head 1, counterweight body 6, the bottom of counterweight head 1 is provided with connection neck 2 and the joint that is connected as a single entity, be provided with hollow chamber 8 in the described counterweight body 6, be provided with metal weights piece 7 in the hollow chamber 8, the internal thread 5 that is provided with suitable for reading of hollow chamber 8, the joint of counterweight head 1 is provided with external thread 4, and counterweight head 1 was fixed on the counterweight body 6 by external thread 4 and cooperating of internal thread 5.Described counterweight head 1 is provided with the compacting ring 3 that compresses counterweight body 6 upper surfaces, can prevent that dust from entering from hickey in the hollow chamber of counterweight body on the one hand, can improve the sealing of hollow chamber on the other hand, prevents metal weights piece 7 oxidation and rustings.
Described counterweight head 1 and counterweight body 6 are preferably made by wear-resisting, heatproof, ageing-resistant fluoroplastic, as materials such as teflon.Described metal weights piece 7 the most handy metallic coppers process, because the various aspects of performance of metallic copper all is better than metallic iron, also can avoid plumbous direct pollution to environment.
