Embodiment 1

A kind of lock screw is mainly used for screw thread and temporarily carries out closing locking.As depicted in figs. 1 and 2, which includes Screw rod and nut 7 are provided with driver flutes or dovetail head (using driver flutes in the present embodiment) on nut 7, can be convenient It is rotated.Wherein, screw rod includes connecting rod 3 and threaded rod 2, connecting rod 3 and 7 integrally connected of nut, in threaded rod 2 Outer surface on be provided with for plate connection locking screw thread itself and plate can be convenient by the screw thread of 2 part of threaded rod Part is threadedly coupled, to achieve the purpose that quickly to screw locking.

As depicted in figs. 1 and 2, between connecting rod 3 and threaded rod 2 be arranged restraining position ring block 4, stop collar 4 be threadedly coupled. Wherein, screw thread includes guide part 21 and limiting section 22, and guide part 21 is smoothly spirally extended to limiting section 22, passes through limiting section 22 It is arranged in parallel with stop collar 4, so that forming card slot 5 between limiting section 22 and stop collar 4, when in use, by rotation, allows hole Edge achievees the purpose that locking hence into arriving in card slot 5 along 21 carry out activity of guide part.Meanwhile it being entered at the edge in hole After in card slot 5, it is further movable not need, and therefore, positive stop strip 23 is arranged in the end of limiting section 22, positive stop strip 23 is distinguished It is wholely set with stop collar 4 and limiting section 22.

After the edge in hole is placed in card slot 5, many times screw can be allowed to be retreated, to allow hole due to pulling door The power of certain relaxation is formed between screw, it is possible to screw and hole be allowed to disengage.In order to reduce the probability of disengagement, such as Fig. 1 and Shown in Fig. 2, the recess 24 limited for inlay card is provided with close to the side of stop collar 4 in limiting section 22, in not rotary screw, Screw is pulled, aperture edge is embedded into recess 24, so that it will not be rotated easily, and then reaches the purpose of limit.

In order to facilitate the installation of screw, as depicted in figs. 1 and 2, connecting rod 3 is divided for the first bar 31 and the second bar 32, is allowed It is integrally formed, and the first bar 31 is wholely set with 7 end of nut, and the second bar 32 is wholely set with threaded rod 2, the first bar 31 Diameter is greater than the diameter of the second bar 32, at this point, during installation, the second bar 32 can be allowed, which easily to pass through, needs hole to be mounted, peace It fills more convenient.Meanwhile during installation, it generally requires one set of placement to limit entire screw, therefore, on the second bar 32 It when being arranged a set, can be positioned (by the diameter difference formed between the first bar 31 and the second bar 32).In order to allow second When bar 32 is inserted into, it will not be hindered by the step between the first bar 31 and the second bar 32, its excessive position is provided with transition part 34, the diameter of 34 one end of transition part is identical as the first bar 31, and the other end is identical as the diameter of the second bar 32, and middle section is straight Diameter even variation is not present step, has the function that guidance.

In order to allow on the second bar 32 set installed to be capable of fixing, it is provided with strip groove 33 on the second bar 32, passes through bar shaped Slot 33 makes its fixation more stable.When opening up strip groove 33, in order to facilitate processing (withdrawing), connecting rod 3 and threaded rod 2 it Between be provided with isolation channel 6.

Embodiment 2

A kind of locking structure is mainly used for the locking in tool box, as shown in figure 3, including the lock being mounted in tool box Fixed board 9 and for carrying out closed door body 8 to tool box, mounting hole 81 is offered in door body 8, is installed in mounting hole 81 There is lock screw 1 as described in Example 1, relock and offer locking hole 91 on plate 9, passes through lock screw 1 and locking hole 91 Cooperation, allows it that can achieve the purpose that locking.In order to make lock screw 1 more convenient when installing, it is arranged in connecting rod 3 solid Surely 10 are covered, and fixing sleeve 10 and door body 8 is allowed to be rotatablely connected.The structure setting of mounting hole 81 is divided into the first hole 82 and at two sections Two holes 83 are cooperated with the first bar 31 and the second bar 32 respectively in conjunction with Fig. 1 and Fig. 3, wherein the aperture in the first hole 82 is big In the diameter of the first bar 31, and the aperture in the first hole 82 is less than the outer diameter of nut 7 and the outer diameter of fixing sleeve 10.And the second hole 83 aperture is greater than the aperture of fixing sleeve 10, at this point, the first bar 31 is allowed to be placed in the first hole 82, the second bar 32 is placed in the second hole 83 It is interior, and it is allowed to be able to carry out rotation.

The course of work: first passing through mounting hole 81 for lock screw 1, then fixing sleeve 10 be set in mounting hole 81, will Lock screw 1 installs.In use, first closing door, make threaded rod 2 corresponding with locking hole 91, by screwdriver or its His tool, rotation lock screw 1, locking hole 91 can cooperate with threaded rod 2, completion locking process；When opening, it will lock Screw is pushed forward, and locking hole 91 is allowed to disengage recess 24, then rotates backward lock screw 1, and then it is de- with locking hole 91 to latch screw 1 It opens, completes opening procedure.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
