Abstract
The utility model relates to a jack protection door and a socket having a jack protection door, solves the problem that a baffle block of an existing jack protection door and a U-shaped support have a large contact surface and thus causing difficult use, and the problem that the baffle block is easy to damage, a wedge-shaped baffle block is replaced by two cylindrical baffle blocks, and the contact areas of the cylindrical baffle blocks and the U-shaped support are small, saving labor in use. The contact friction of the cylindrical baffle blocks and the plug is small, facilitating insertion of the plug, and the baffle blocks can retreat towards one side under the function of a relatively small force, and the baffle blocks are not damaged or the damage to the baffle blocks is relatively small. The jack protection door is suitable for anti-electric-shock protection for children, and is applicable to various sockets at the same time.
Description
Technical field
The utility model relates to and a kind ofly prevents that jack from causing the protective device of electric shock, is specifically related to a kind of insertion hole protection door.
Background technology
the jack of known insert row socket is provided with shutter, can prevent from getting an electric shock, can directly see simultaneously inner exposed energized conductor, its structure as shown in Figure 1, under the jack direction of insertion, by top panel, the U-shaped bearing consists of a flat box body, be provided with link stopper and spring in box body, block is a part that cross section is wedge shape, when plug inserts from jack, plug is to active force of wedge surface of link stopper, block two lateralizations are decorporated, when plug is extracted, plug disappears to the wedge surface active force of link stopper, link stopper returns to original position under the elastic force effect of spring, shelter from inner exposed energized conductor.
There are the following problems for this structure: the lower surface of (1) wedge shape link stopper and the contact area of U-shaped bearing are large, make lower surface and the force of sliding friction between the U-shaped bearing of wedge shape link stopper large, need to block be decorporated with larger power, for the less people of strength, especially children use very inconvenient.(2) wedge surface of plug and link stopper is had an effect, and often uses, and easily causes wedge surface to damage, and then causes the disabler of block, can't decorporate smoothly, does not have protective effect.
Summary of the invention
For the block that overcomes existing insertion hole protection door and the use effort problem that U-shaped bearing contact-making surface causes greatly, and the flimsy problem of block, the utility model provides a kind of insertion hole protection door with cylindrical block.
The technical scheme that its technical problem that solves the utility model adopts is:
a kind of insertion hole protection door, comprise the U-shaped bearing, be provided with block in the U-shaped bearing, block is connected with the U-shaped bearing by elastomeric element, the bottom surface of U-shaped bearing is provided with lower jack, described block is cylindrical block, described elastomeric element is the U-shaped shell fragment, corresponding two the cylindrical blocks of lower jack, the axial direction of described two cylindrical blocks is consistent with the length direction of lower jack, the center of the same end of described two cylindrical blocks is connected with two free ends of a U-shaped shell fragment respectively, the center of the other end of described two cylindrical blocks is connected with two free ends of another U-shaped shell fragment respectively, the centre position of U-shaped shell fragment is fixedly connected with the U-shaped bearing.
The length of two cylindrical blocks is greater than the length of lower jack.
The diameter of two cylindrical blocks and greater than the width of lower jack.
Cylindrical block replaces with oval block.
a kind of socket with insertion hole protection door, comprise top panel, top panel is provided with jack, the lower surface of top panel is fixed with the U-shaped bearing, be provided with cylindrical block and U-shaped shell fragment in the U-shaped bearing, be provided with the lower jack corresponding with upper jack position on the U-shaped bearing, the axial direction of two cylindrical blocks is consistent with the length direction of upper jack, the center of the same end of described two cylindrical blocks is connected with two free ends of a U-shaped shell fragment respectively, the center of the other end of described two cylindrical blocks is connected with two free ends of another U-shaped shell fragment respectively, the centre position of U-shaped shell fragment is fixedly connected with the U-shaped bearing.
The corresponding U-shaped bearing of upper jack.
Corresponding U-shaped bearing of jack on one group.
The corresponding U-shaped bearing of the upper jack of many groups.
Corresponding U-shaped bearing of jack on all.
The beneficial effects of the utility model are:
(1) contact area of cylindrical block and U-shaped bearing is little, uses laborsaving.
(2) contact friction of cylindrical block and plug is little, be convenient to plug and insert, and block namely can decorporate to a side under the effect of less power, can be to block injury or less to the damage of block.
(3) be applicable to electrocution-proof protection to children, be applicable to simultaneously various sockets.

Embodiment
a kind of insertion hole protection door, comprise U-shaped bearing 2, be provided with block in U-shaped bearing 2, block is connected with U-shaped bearing 2 by elastomeric element, the bottom surface of U-shaped bearing 2 is provided with lower jack 6, block is cylindrical block 3, elastomeric element is U-shaped shell fragment 4, corresponding two the cylindrical blocks 3 of lower jack 6, the axial direction of two cylindrical blocks 3 is consistent with the length direction of lower jack 6, the center of the same end of two cylindrical blocks 3 is connected with two free ends of a U-shaped shell fragment 4 respectively, the center of the other end of two cylindrical blocks 3 is connected with two free ends of another U-shaped shell fragment 4 respectively, the centre position of U-shaped shell fragment 4 is fixedly connected with U-shaped bearing 2.
Insertion hole protection door of the present utility model can be applied on insert row or socket, also can be applied to other and need to prevent human body and the occasion that electrically contacts.
For example, in Fig. 2, the top panel 1 of socket insert row is provided with the upper jack 5 suitable with plug position, the lower surface of top panel 1 is fixed with U-shaped bearing 2, the corresponding U-shaped bearing 2 of upper jack 5, perhaps corresponding U-shaped bearing 2 of jack 5 on a group, the perhaps corresponding U-shaped bearings 2 of the upper jack 5 of many groups, perhaps U-shaped bearing 2 of jack 5 correspondences all on.Top panel 1 and U-shaped bearing 2 form a flat box body that is similar to rectangle, jack 6 under being provided with corresponding with upper jack 5 positions of the bottom surface of U-shaped bearing 2.
be provided with cylindrical block 3 and U-shaped shell fragment 4 in U-shaped bearing 2, upper jack 5 corresponding two cylindrical blocks 3 and U-shaped shell fragments 4, the axial direction of cylindrical block 3 is consistent with the length direction of upper jack 5, two ends of cylindrical block 3 connect by U-shaped shell fragment 4 respectively, two free ends of U-shaped shell fragment 4 extend fixed axis to the axial direction of cylindrical block 3, fixed axis inserts respectively the center of the end of cylindrical block 3, it is fixing that screw or rivet and U-shaped bearing 2 are passed through in the center of U-shaped shell fragment 4, or other can be fixed U-shaped shell fragment 4 but not affect the fixed form that U-shaped shell fragment 4 shell fragments move.Better, removably connect between cylindrical block 3 and U-shaped shell fragment 4, be convenient to more shift block and U-shaped shell fragment 4, also be convenient to maintenance.
