A glass substrate containing, in terms of mol% on the basis of the following oxides: from 60 to 79% of SiO 2 ; from 2.5 to 18% of Al 2 O 3 ; from 0 to 3% of B 2 O 3 ; from 1 to 15% of MgO; from 0 to 1% of CaO; from 0 to 1% of SrO; from 0 to 1% of BaO; from 0 to 1% of ZrO 2 ; from 7 to 15.5% of Na 2 O; from 0 to 3% of K 2 O; and from 0 to 2% of Li 2 O; wherein Na 2 O+K 2 O is from 7 to 15.5%, Na 2 O / (Na 2 O+K 2 O) is from 0.77 to 1, MgO+CaO+SrO+BaO is from 1 to 18%, MgO-0.5Al 2 O 3 is from 0 to 10, and MgO+0.5Al 2 O 3 is from 1 to 20, wherein the glass substrate has: a glass transition temperature of from 580 to 720 DEG C; an average coefficient of thermal expansion within a range of from 50 to 350 DEG C of from 6510 -7 to 8510 -7 / DEG C; a compaction (C) of 15 ppm or less; a glass surface devitrification temperature (T c ) of from 900 to 1,300 DEG C; a glass internal devitrification temperature (T d ) of from 900 to 1,300 DEG C; a temperature (T 4 ) at which a viscosity reaches 10 4 dPas of from 1,100 to 1,350 DEG C; a relationship (T 4 -T c ) between the temperature (T 4 ) at which a viscosity reaches 10 4 dPas and the glass surface devitrification temperature (T c ) of from -50 to 350 DEG C; and a relationship (T 4 -T d ) between the temperature (T 4 ) at which a viscosity reaches 10 4 dPas and the glass internal devitrification temperature (T d ) of from -50 to 350 DEG C.

The invention discloses a locking device used for a box body, which comprises a lock cover (2) and a lock core (3), wherein one end of the lock cover (3) is hinged on a first box body (11), and the other end of the lock cover (2) is hinged with the lock core (3) through a pin shaft (4); the lock core (3) is arranged at the inner side of the lock cover (2); a spring (5) is arranged between the lock core (3) and the lock cover (2); a lock catch part (121) is arranged on a second box body (12); and the lock core (3) is provided with a lock head (31) matched with the lock catch part (121). The locking device used for the box body has the advantages that locking device can be used for locking firmly and reliably, is not easy to stagger, is not easy to open accidentally, and is convenient in use, and rapid and efficient in opening and closing; and articles in the box can be kept well;.

The present invention discloses an expansion seat for connecting an electronic device. The expansion seat comprises a body, a baffle and at least one driving part. The body comprises a connecting part, a first opening and an accommodating space, wherein the connecting part is arranged in the accommodating space. The baffle is connected with the body movably and is arranged in the accommodating space, the baffle possesses a second opening at the position corresponding to the connecting part. The at least one driving part is connected with the body and abuts against the baffle, wherein when entering the accommodating space from the first opening, the electronic device abuts against the baffle and the driving part to the connecting part, and the connecting part is electrically connected with the electronic device via the second opening. When the electronic device is taken out from the accommodating space, the driving part returns the baffle back to the original position. The expansion seat of the present invention can align accurately and possesses a protective effect.

There is provided an outer mirror with turn lamp that facilitates assembling of a housing cover to a mirror housing and increases strength of the housing cover. A turn lamp assembly (16) is mounted to a mirror housing (10). A housing cover (24) is placed over and mounted to a partial area of the mirror housing (10). Thus, a lens (20) of the turn lamp assembly (16) is exposed through an opening (28) formed in an outer position of the housing cover (24). The mirror housing (10) and the housing cover (24) are connected to each other with a ridge (13) and a groove (30) in end surfaces (11, 29) and abutting against and fitting each other. On a wall (30a) on an inner side of the mirror that constitutes a part of the component of the groove (30) in the housing cover (24), at an assembling start position (32) in an outer position outside the opening, an assembling leading rib (34) is formed that protrudes in a direction abutting against the end surface (11) of the mirror housing (10).

The invention provides a wire harness protecting structure which is used for protecting a plugging terminal of a wire harness. The wire harness protecting structure comprises a cavity for containing the plugging terminal, wherein a containing structure recessed towards the inside of the cavity is arranged at the first end of the cavity and allows the wire harness to pass through, the cavity can be turned with the containing structure as the center, the inner wall of the cavity is changed into the outer wall of the cavity after turning, and the plugging terminal is wrapped in the cavity. Accordingly, the invention further provides the wire harness. Through the technical scheme, on one hand, the installation steps of the wire harness protecting structure can be effectively simplified, then the operation convenience and production efficiency are improved, and meanwhile the overall machine consistency of the wire harness protection structure is ensured; on the other hand, the protecting structure does not need to be fixed through additional material, and meanwhile the production cost is reduced.
