the third baffle 10 and the fourth baffle 20 are respectively connected with the second sliding rail 80 in a sliding way, the second sliding rail 80 is also provided with a fixing part 60, the fixing part 60 is arranged between the third baffle 10 and the fourth baffle 20, the third baffle 10 is elastically connected with the fixing part 60 through a third elastic piece 41, the fourth baffle 20 is elastically connected with the mounting seat 30 through a fourth elastic piece 42, the third baffle 10 is provided with a fifth inclined surface 11 and a sixth inclined surface 12 which incline along the same direction, the fourth baffle 20 is provided with a seventh inclined surface 21 and an eighth inclined surface 22 which are arranged in a V shape, the third baffle 10 slides and shows a third jack 70 when the fifth inclined surface 11 and the sixth inclined surface 12 are simultaneously pressed, and the fourth baffle 20 slides and shows a third jack 70 when the seventh inclined surface 21 and the eighth inclined surface 22 are simultaneously pressed; the third barrier 10 and the fourth barrier 20 slide in the same direction.

The second accommodating portion has at least two second stopping portions, a space is provided between the third baffle 10 and the second bottom end surface, and when one side of the third baffle 10 is pressed, the third baffle 10 inclines to one side and abuts against the second stopping portions.

Specifically, protruding ribs may be disposed at the lower portions of the third baffle 10 and the fourth baffle 20, the second sliding rail 80 is concave on the second bottom end surface, and the third baffle 10 and the fourth baffle 20 slide on the second sliding rail 80 in a limited manner through the protruding ribs. It will be appreciated that the ribs may be modified to other conventional raised structures.

Specifically, when the third baffle 10 is embedded in the second sliding rail 80, a gap is formed between the third baffle 10 and the second bottom end surface. That is, the lower end surface of the third shutter 10 is above the second bottom end surface. The upper end surface of the second stop is between the third baffle plate 10 and the second bottom end surface.

Specifically, the second sliding rail 80 extends along the compressing direction of the third elastic member 41 and is located on the central axis of the second bottom end surface.

Specifically, the fourth baffle 20 abuts against the fixing portion 60. And the upper end surface end of the fixing portion 60 has an extended positioning portion. When the fourth baffle 20 abuts against the fixing portion 60, the lower end face of the positioning portion is just attached to the upper end face of the fourth baffle 20, so that the positioning function of the fourth baffle 20 is achieved, and positioning is facilitated during installation.

Specifically, in the present embodiment, referring to fig. 1 and 2, the mounting base 30 has a square column-shaped second accommodating portion with an open upper end. Three third insertion holes 70 are arranged at a lateral interval on the upper half part of the bottom surface of the second accommodating part. Wherein the third jack 70 on the left and the third jack 70 on the right are spaced a distance just in line with the spacing of the two-hole plug so that the two-hole plug can pass through both the third jack 70 on the left and the third jack 70 on the right. A second slide rail 80 is arranged on the central axis of the left and right third jacks 70. The jack located in the middle of the three third jacks 70 is provided on the second slide rail 80. Two third insertion holes 70 are arranged at a lateral interval on the lower half part of the bottom surface of the second accommodating part, a fixing part 60 is arranged between the two third insertion holes 70 and positioned on the second sliding rail 80, and one end of the fixing part 60 facing the upper half part of the bottom surface of the second accommodating part is provided with an opening. Four linear second stop parts extending along the connecting parts are arranged at the connecting parts between the side surfaces and the bottom surfaces of the second accommodating parts. The second stop part is a straight-line convex block. Specifically, an upper stopper 51 located between the third barrier 10 and the fourth barrier 20 and a lower stopper 52 located below both end portions of the fourth barrier 20, respectively. The upper stop part 51 and the lower stop part 52 positioned at the left are arranged at the joint of the left end surface and the second bottom end surface of the second accommodating part; the upper stopper 51 and the lower stopper 52 on the right are provided at the junction of the right side end surface and the second bottom end surface of the second accommodation portion. Referring to fig. 1 again, the third baffle 10 is formed by a rectangular sleeving part, and a first covering part and a second covering part extending from two symmetrical sides of the sleeving part. The sleeve portion has a fourth insertion hole 13. The upper end surfaces of the first cover part and the second cover part are respectively a fifth inclined surface 11 and a sixth inclined surface 12 which are inclined upwards. When the third barrier 10 is balanced and stationary, the fourth insertion hole 13 coincides with the third insertion hole 70 directly thereunder. The lower end surface of the sheathing part passes through the opening of the fixing part 60 by the third elastic member 41 and is fixed thereto. The fourth baffle 20 is substantially V-shaped, and the second baffle 20 is also formed by a sleeve portion and third and fourth cover portions extending from both sides of the sleeve portion, and upper end surfaces of the third and fourth cover portions are respectively a seventh inclined surface 21 and an eighth inclined surface 22 inclined obliquely upward. The lower end surface of the second baffle 20 also has an opening, through which one end of the fourth elastic member 42 is connected to the second baffle 20, and the other end of the fourth elastic member 42 is fixed to the lower end surface of the mounting base 30 along the second slide rail 80. The socket can be a small portable socket, has small whole volume and can be held by a user with one hand.

Next, i say the operation of the protective door assembly:

when the third baffle 10 is not stressed, the fourth jack 13 coincides with the third jack 70 thereunder. The three-hole plug can be inserted into the fourth insertion hole 13, and at this time, the other two plugs of the three-hole plug press the seventh inclined surface 21 and the eighth inclined surface 22, and since the inclination directions of the seventh inclined surface 21 and the eighth inclined surface 22 are the same, the fourth barrier 20 receives a downward force, and thus the fourth barrier 20 moves downward and compresses the fourth elastic member 42. During the downward movement of the fourth shutter 20, the third insertion hole 70 located at the second receiving portion is exposed and may further pass through the third insertion hole 70. Similarly, when the two-hole plug is inserted, the third baffle 10 moves downward. The third baffle 10 and the fourth baffle 20 can slide on the second slide rail 80. (the mounting base 30 has five first jacks 31 corresponding to the two-jack plug and the three-jack plug respectively)

Next, a specific case will be described. When only one of the fifth inclined surface 11 and the sixth inclined surface 12 receives pressure, for example, the conductive foreign matter presses only one of the inclined surfaces, or the child's finger touches one of the insertion holes by mistake, the pressed inclined surface of the third baffle plate 10 receives a pressing force and a sliding force. The pressed single side of the third barrier 10 is inclined downward and slides down. Since the upper stopper plate 51 is in the form of a boss, it is high with respect to the bottom surface of the mounting base 30, and there is a gap between the left and right sides of the third stopper plate 10 and the second bottom end surface, i.e., the lower end surface of the third stopper plate 10 is above the second bottom end surface. The upper end surface of the second stopper 51 is between the third barrier 10 and the second bottom end surface. When the pressed single side of the third baffle 10 is inclined downward, it means that the height of the pressed single side of the third baffle 10 relative to the bottom surface of the mounting seat 30 is lower, and the height of the pressed single side of the third baffle 10 relative to the bottom surface of the mounting seat 30 is lower than the height of the upper stop plate 51 relative to the bottom surface of the mounting seat 30 after the third baffle 10 is lowered when the pressing force can drive the third baffle 10 to slide downward. This means that the third baffle-plate 10 will slide down against the end of the upper stop plate 51 and will not slide down. And further, the third insertion hole 70 on the bottom surface of the mounting seat 30 cannot be exposed when the third baffle 10 is pressed on one side. In the same principle, a gap is formed between the left and right sides of the fourth baffle 20 and the second bottom end surface, i.e., the lower end surface of the fourth baffle 20 is above the second bottom end surface. The upper end surface of the lower stopper 52 is between the third barrier 10 and the second bottom end surface. When one side of the fourth baffle 20 is extruded, the extruded side is subjected to downward pressure and downward sliding force, and the relevant dimensions are designed, so that when the extruded side of the fourth baffle 20 is extruded and slides down, the height of the extruded side of the fourth baffle 20 relative to the bottom surface of the mounting seat 30 is lower than the height of the lower stop part 52 relative to the bottom surface of the mounting seat 30, and further, the end part abutting against the lower stop part 52 when one side of the fourth baffle 20 is extruded and slides down cannot slide down continuously.

According to the protective door assembly provided by the utility model, the sliding of the third baffle plate 10 and the fourth baffle plate 20 is controlled by two elastic pieces instead of one elastic piece, and the third baffle plate 10 and the fourth baffle plate 20 slide in the same direction, so that the durability and the safety of long-term use are improved.

That is, the third baffle 10 does not cover the uppermost jack of the three-jack socket any more, and the cost is saved on the premise of not affecting the safety.
