Sleeve

Abstract

The invention discloses a sleeve, and particularly discloses a movable sleeve with a large thickness. The sleeve provides unlocking or locking of nuts with continuous level pitch size outer diametersby stronger force application strength, and can achieve multiple changes in size. According to the sleeve, force application blocks and limiting grooves are formed in the inner diameter of a hollow accommodating chamber of an outer sleeve, wherein the force application blocks and the limiting grooves are equally arranged in a circular mode and continuously adjacent. The limiting grooves can enablelimiting seats of a first movable sleeve body to perform sleeving, and the first movable sleeve body is mainly provided with a plurality of annularly arranged force application sections at the frontend of a shaft seat. The force application sections are limited in the limiting grooves of the outer sleeve in a sleeved mode by the limiting seats at top ends of the force application sections. Forceapplication seats are integrally formed at the limiting seats in the direction towards the interior of the hollow accommodating chamber, and the inner diameters of the force application seats form force application surfaces, wherein the force application seats are conical surfaces contracting gradually towards the direction of the force application surfaces. One end of an elastic assembly sleevesthe first shaft seat, and the sleeve can provide unlocking or locking of two nuts with the continuous level pitch size outer diameters.

Description

technical field [0001] The invention relates to a sleeve, especially a movable sleeve that can provide a thicker thickness, and provide a continuous level of unlocking or locking of the outer diameter of the nut with a stronger force strength, and can achieve multiple Sockets of varying sizes. Background technique [0002] According to the size of commonly used nuts, it can be roughly divided into 9mm, 11mm, 13mm, 15mm, 17mm, 19mm, 21mm, 23mm... and so on. Car restoration or construction sites, obviously no longer meet the needs, so, that is, as Figure 1 to Figure 5 The sleeve shown can provide two kinds of nuts with different sizes. The sleeve mainly includes an outer sleeve 1 and a first inner sleeve 2, wherein: [0003] An outer sleeve 1, one end of the outer sleeve 1 is a tool joint 11 for the tool socket to apply force, and one end different from the tool joint 11 is a workpiece joint 12, and the inner diameter of the work joint 12 is a first A hollow chamber of an i...

Problems solved by technology

[0006] For the structure that provides two kinds of nuts with different sizes in this way, for the convenience of construction, it is usually designed to provide continuous size nuts for its sleeve, that is, the sleeve will be 9mm, 11mm or 11mm, 13mm or 13mm, 15mm or 15mm, 17mm... and so on, the continuous step size design, when the inner diameter of the first inner hexagonal fitting section 13 (HEX1) of the outer sleeve 1 is 15mm, the second inner hexagonal fitting section of the inner sleeve 2 21 (HEX2) has an inner diameter of 13mm, so the wall thickness T of the inner sleeve 2 depends on the inner diameter of the second inner hexagon fitting section 21 (HEX2) of the inner sleeve 2 and the first inner diameter of the outer sleeve 1. The size gap of the inner diameter of the inner hexagonal fitting section 13 (HEX1), that is, T=HEX1-HEX2, so, at this time, the single-sided wall thickness T of the inner sleeve 2 is (HEX1-HEX2)÷2=1mm, so 1mm The wall thickness T is to withstand the torsion force of the inner sleeve 2, which is obviously insufficient and prone to deformation. In order to achieve the strength required to withstand the torsion without deformation, the inner sleeve set 2 needs to be With a wall thickness T such as 2mm, the sleeve can only provide sleeves with discontinuous size steps such as 13mm, 17mm or 15mm, 19mm, etc., but cannot provide sleeves with continuous size steps, so that users If you can’t roughly judge the size of the nut (such as 13mm or 15mm), you can use the sleeve with a continuous step size of 13-15mm, and you need to correctly judge the size of the nut is about 13mm or 15mm, and then find the correct size The sleeve can only be moved, thus increasing the work trouble

[0007] see again Figure 8 As shown, it is a schematic example of an embodiment, a second inner sleeve 3 or more movable sleeves can also be sleeved in the inner sleeve 2, but the sleeve can provide 3 or 3 different but Continuous size nuts are used, but the thickness of the same wall thickness T is obviously insufficient, and it is easy to cause deformation
