Abstract
The utility model relates to a length adjustable tool, relating to a tool which can randomly adjust the self length, the length adjustable tool comprises a nut 2, and a screw (1) and a screw (2) which can simultaneously be screwed in the inner chamber of the nut 2 by threads, the utility model is characterized in that the screw (1) and the screw (2) are two screws with different diameters and same screw pitches and adverse directions of rotation, an inner chamber is provided at one end of the big screw (1), the screw (2) is stretched into the inner chamber of the big screw (1), when the nut 2 is rotated and the tool is shortened, the screw (1) can hold the contraction of the screw (2), the tool can be very convenient to adjust the whole tool length, and the structure is compact, the room availability of the nut is high.
Description
One, technical field:
The utility model relates to a kind of instrument, the particularly a kind of facility that can regulate self length arbitrarily.
Two, background technique:
Existing length adjustment facility as shown in Figure 2, comprise screw rod I (4), nut 5, screw rod II (6), screw rod I is two screw rods that diameter is the same, rotation direction is opposite with screw rod II, when swivel nut 5, screw rod I and screw rod II stretch out and the length of shrinking, influenced whole facility, thus the length of having regulated whole facility easily.Its deficiency is that the space availability ratio of facility nut is low.
Three, summary of the invention:
Technical problem to be solved in the utility model is: solve the low problem of space availability ratio of existing length adjustment facility nut, provide a kind of and can regulate the length of whole facility, the length adjustment facility that structure is compacter again, the nut space utilization ratio is also high easily.
For this reason, solution of the present utility model is: will overlap the screw rod I, the screw rod II that are spun on nut intracavity simultaneously by screw thread and make the screw rod that two diameter differ, pitch is identical, rotation direction is opposite, small screw II is enclosed within the inner chamber of big screw rod I, thereby has maximally utilised the space of nut.
Its concrete structure is: a kind of length adjustment facility, comprise nut, overlap screw rod I, the screw rod II that is spun on nut intracavity by screw thread simultaneously, it is characterized in that: screw rod I is the screw rod that two diameter differ, pitch is identical, rotation direction is opposite with screw rod II, end at big screw rod I is processed an inner chamber, and small screw II stretches in the inner chamber of big screw rod I.
Because the screw rod I of the length adjustment facility of the utility model is two screw rods not of uniform size, that pitch is identical, rotation direction is opposite with screw rod II, end at big screw rod I is processed with an inner chamber, screw rod II stretches in the inner chamber of big screw rod I, work as swivel nut, when facility shortened, screw rod I can hold the indentation of screw rod II; Under same nut space length, make two screw rods that the relative displacement of two nut length nearly be arranged, thereby maximally utilised the space of nut; Compare with similar facility, this patent compact structure, shorten length nearly half.
Four, description of drawings:
Fig. 1: the length adjustment implement structure schematic representation of the utility model;
Fig. 2: existing length adjustment implement structure schematic representation;
Five: embodiment:
A kind of length adjustment facility, comprise nut 2, overlap screw rod I (1), the screw rod II (3) that is spun on nut 2 inner chambers by screw thread simultaneously, screw rod I (1) is the screw rod that two diameter differ, pitch is identical, rotation direction is opposite with screw rod II (3), end at big screw rod I (1) is processed with an inner chamber, screw rod II (3) stretches in the inner chamber of big screw rod I (1), when swivel nut 2, when facility shortened, screw rod I can hold the indentation of screw rod II.
Claims (1)
1, a kind of length adjustment facility, relate to a kind of facility that can regulate self length arbitrarily, comprise nut (2), overlap screw rod I (1), the screw rod II (3) that is spun on nut (2) inner chamber by screw thread simultaneously, it is characterized in that: screw rod I (1) is two screw rods that diameter is inconsistent, pitch is identical, rotation direction is opposite with screw rod II (3), end at major diameter screw rod I (1) is processed with an inner chamber, and minor diameter screw rod II (3) can stretch in the inner chamber of major diameter screw rod I (1).
