Description

Technical Field

[0001] The utility model relates to the technical field of tape measures, in particular to an openable and closable tape measure housing. Background Art

[0002] The tape measure is a commonly used length measuring tool in production and life. It has a simple structure and is easy to carry.

[0003] During the use of the tape measure, the dirt carried on the tape is collected into the tape housing, causing the tape to get stuck when it is retracted or extended. To solve this technical problem, technicians in this field have developed a variety of automatic cleaning devices, such as installing a wiping structure that matches the tape on the housing, and also providing an inspection port on the tape measure. The inspection port is machined on the side of the tape housing and is sealed by a box cover. The inspection area is small and affects the overall appearance. Utility Model Content

[0006] Furthermore, the inspection opening occupies an angle of 100°-180°.

[0007] Furthermore, the upper end of the inspection opening extends to the upper part of the main shell, the upper end of the auxiliary shell is hinged to the main shell, and a locking device is provided between the lower end of the auxiliary shell and the main shell.

[0008] Furthermore, the locking device includes a connecting plate hinged to the lower end of the auxiliary housing, a plug plate is provided at the end of the connecting plate, and a slot matching the plug plate is provided on the main housing.

[0009] Furthermore, the plug board is provided with a barb that matches the slot.

[0010] Furthermore, a snap-fit ​​sleeve is provided on the upper end of the connecting plate, the side of the snap-fit ​​sleeve is open, and a connecting shaft matching the snap-fit ​​sleeve is provided on the lower end of the auxiliary shell, and the snap-fit ​​sleeve is interference-fitted on the connecting shaft.

[0011] Furthermore, a positioning plate cooperating with the auxiliary shell is provided on the inner side of the inspection port, and a positioning groove cooperating with the positioning plate is provided on the inner side of the auxiliary shell.

[0012] Furthermore, the positioning plate is connected to the side wall of the positioning groove by interference fit.

[0013] The beneficial effects of the present invention are:

[0014] 1. It includes a main housing with an inspection opening. A closable auxiliary housing is provided at the inspection opening. The inspection opening is arranged on the circumference of the main housing, dividing the ruler housing into two parts. This does not affect the overall appearance and can provide a larger operating space. The corresponding inspection opening area is larger, allowing for inspection of more locations.

[0015] 2. A locking device is provided to lock the main housing and the auxiliary housing, thereby making the connection between the main housing and the auxiliary housing stable. BRIEF DESCRIPTION OF THE DRAWINGS
