It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

As shown in fig. 1-4, the utility model provides a short bolt, including casing 1, rotatable spanner 2, the mobilizable bolt pole 3 of locating casing 1 one side of locating on casing 1 of locating, be connected with connection piece 4 between spanner 2 and the bolt pole 3, and be between spanner 2 and the connection piece 4, be the rotation between bolt pole 3 and the connection piece 4 and be connected, when spanner 2 rotated for casing 1, bolt pole 3 removed for casing 1.

When wholly installing the bolt, aim at the notch of section bar with the tip of bolt pole, on the basis that keeps bolt pole tip position afterwards, carry out fixed mounting to the casing, so that the bolt pole still aims at the notch position behind the casing installation, and because when the casing is fixed to be accomplished, the spanner, spare parts such as bolt pole and connection piece all fix the completion along with the casing is synchronous, therefore in the installation of this scheme, only need carry out independent installation operation in proper order to the casing, need not to carry out installation respectively many times to each spare part, very big reduction the operating procedure of bolt installation, improve the convenience and the efficiency of bolt installation, and because the casing is fixed the back, the bolt pole need not and fix a position between the casing, therefore the location of bolt pole can be guaranteed, increase the location accuracy between bolt pole and the notch.

In addition, when the locking cooperation of bolt pole and notch needs to be used, rotate the spanner and drive the bolt pole through the connection piece and remove, and then make the bolt pole detain and break away from for the notch, can reach door and window locking, the purpose of opening.

Wherein, form the connecting rod between spanner, bolt pole and the connection piece to guarantee the stability when spanner drives the bolt pole and removes.

Preferably, a guide rail 5 is formed at one side of the housing 1, and the latch rod 3 is movably disposed in the guide rail 5.

Concretely, because the bolt pole needs to remove for the casing, and then accomplish the locking and the open mode of door and window and adjust, consequently lead to the bolt pole through the guide rail, can increase the accuracy that the bolt pole removed the in-process, avoid bolt pole tip and notch to appear interfering the unable circumstances of locking

Preferably, a sliding block 6 is movably arranged in the shell 1, one side of the sliding block 6 is connected with the bolt rod 3, and the other side of the sliding block 6 is rotatably connected with the connecting piece 4.

It is specific, because the spanner drives the connection piece through the pivoted mode and carries out the pivoted, consequently, when the connection piece drives the bolt pole and removes, the bolt pole must receive the ascending pulling force of connection piece rotation side, and then make the bolt pole upwards lift up, increase the frictional force between bolt pole and the guide rail, this scheme is through adding the slider structure, make the connection piece at first drive the slider and remove, drive the bolt pole through the slider afterwards and remove, very big reduction the connecting piece to the direct upwards pulling force that produces of bolt pole, and then reduced the frictional force between bolt pole and the guide rail, increase the life of bolt pole.

Preferably, the rotating shafts 7 are arranged between the wrench 2 and the connecting piece 4, between the sliding block 6 and the connecting piece 4, and between the wrench 2 and the shell 1.

By the setting of pivot structure, on guaranteeing the rotatable coupling basis between each junction, increased pivoted stability to be connected to the back on the casing with the both ends of pivot, can each rotation junction's of effectual increase location accuracy, avoid rotating the possibility that the in-process appears rocking.

Preferably, the shell 1 is provided with a spring piece 8 inside, and the spring piece 8 is abutted against one side of the rotary connection part of the wrench 2 and the shell 1.

Specifically, because the spring leaf can support the spanner and rotate one side of junction with the casing under normal condition, consequently can exert pressure to this department through the spring leaf, under the spanner pulling bolt pole contracts and then opens door and window's state promptly and the spanner promotes bolt pole and locks door and window's state, all can carry out spacingly through the spring leaf to the rotation state of spanner, and then increase the locking of bolt pole, the stability of opening the state.

The spring piece is prior art and is not described in detail here.

Preferably, one side of the spring piece 8 is provided with a protruding structure, so that the protruding structure part of the spring piece can be more attached to one side of the rotary connection part of the wrench and the shell, and the position stability of the wrench in the locking and opening states of the bolt rod is further improved.

Preferably, one side of the guide rail 5 is provided with a through hole 9.

Specifically, the user can follow the inside bolt pole user state of guide rail outside observation by the through-hole position, for example rust, the condition such as wearing and tearing, simultaneously when needs are cleared up the bolt pole, can aim at the through-hole position with equipment such as hair-dryer, and then blow dirt to the bolt pole of guide rail and inside, in order to reach the inside effect of clearance, and need not to dismantle bolt overall structure, in addition because the bolt pole is after long-time use, need add lubricating oil to it, consequently can be convenient lubricate the shift position to the inside of guide rail and bolt pole by the through-hole position, increase the life of bolt pole.

Preferably, the end of the latch rod 3 remote from the housing 1 is provided with a protective sleeve 10.

Specifically, because the bolt rod needs to be frequently buckled into the notch or separated from the notch, abrasion and sliding friction of the end part are easily generated, and therefore the end part of the bolt rod is sleeved with the protective sleeve, the safety of the end part of the bolt rod can be effectively improved, and the service life of the end part of the bolt rod can be effectively prolonged.

In one embodiment of the present disclosure, the protective sleeve is made of rubber.

In another embodiment of the present solution, the external dimensions of the protective casing can be adjusted according to the internal dimensions of the slot, and a variety of different sizes of protective casings can be collocated on the end of the same latch rod to meet the installation requirements of users.

The present invention is not limited to the above preferred embodiments, and any person can obtain other products in various forms without changing the shape or structure of the product, and all the products having the same or similar technical solutions as the present invention fall within the protection scope of the present invention.
