Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown in Figure 5, the housing for the tape measure includes an upper cover 1 and a lower cover 2 that are assembled together and a rubber layer 3 arranged on the outer surfaces of the two;

[0015] Wherein, the upper cover 1 and the lower cover 2 are all embedded in the plastic base layer 11, 21 with the metal core cover 12, 22 in the form of integral injection molding, and the outer surface of the corresponding rubber layer 3 is the plastic base layer 11 ,twenty one;

[0016] The plastic base layer 11 of the upper cover 1 is in the form of a frame, and its top is provided with a raised portion 11a, while the metal core cover 12 is correspondingly provided with a small hole 12a, through which the raised portion 11a of the plastic base layer 11 and the metal The cooperation of the small hole 12a on the core cover 1...

Abstract

The invention discloses a shell for band tape, which comprises: an upper cover (1) with a frame-shape plastic substrate (11) joint with a lower cover (2) both embedded metal core cover (12) into a plastic substrate by integrated injection molding, and a rubber layer (3) on outside of (1) and (2). Wherein, arranging a bulge (11a) on top of (11) and a small hole (12a) on (12) both matched to block (12) on the plastic substrate (11). Compared with prior art, this invention enhances fastness of whole shell with little effect to rubber layer and band tape appearance.

Description

technical field [0001] The invention relates to the technical field of measuring tapes, in particular to a casing for measuring tapes. Background technique [0002] As a commonly used portable measuring tool, tape measure is indispensable in construction work such as carpentry, masonry, and mechanics. A tape measure is generally composed of a housing and a retractable ruler tape arranged therein. The housing of a tape measure on the market is generally composed of an upper cover and a lower cover, and the upper cover and the lower cover are mostly made of plastic material. Because of the characteristics of the plastic material, this kind of casing used for measuring tape is easy to slip and difficult to take in actual use. Therefore, there are some casings with rubber layers on the outer surface of the upper and lower covers, that is, the upper and lower covers made of plastic The outer part is attached with a rubber layer, so that when the fingers are holding the tape meas...
