Abstract

The utility model discloses a bolt with the functions of bidirectional and automatic limiting. The bolt comprises a bolt base and a bolt latch, wherein a pin cylinder is arranged on the bolt base, a closed guide groove is formed at the middle part of the pin cylinder; the bolt latch is arranged in the pin cylinder in a sliding manner; bolt latch limit grooves are symmetrically formed at the two ends of the guide groove; an elastic element is arranged at the middle part of the bolt latch; the bolt latch limit grooves are symmetrically and vertically formed at the two ends of the guide groove on the same side; and a bolt handle is inserted in the limit grooves in a clamped manner. The utility model effectively reduces the overall size of the bolt; the bolt latch can extend from either end of the bolt base for locking, thereby reducing the mounting space of the bolt and achieving the applicability for the locking of various doors, windows and covered equipment; and when the bolt latch slides to the bolt latch limit grooves, the bolt handle can be automatically inserted into the bolt latch limit grooves at both ends of the bolt base under the torsion force of a torsion spring to lock the bolt, so as to eliminate the locking failure due to shakes during vehicle transportation or equipment conveyance.

Description

Two-way from spacing latch

Technical field

The utility model relates to a kind of locking device, and especially a kind of latch locking device is applicable to various vehicle-mounted or civilian doors, window, the locking of top box cabinet is arranged.Belong to daily hardware technology field.

Background technology

At present, at door, window or cover widely used latch class locking device on the equipment, no matter lock-out state or opening, the latch door bolt can both easily freely rotate, and when locking be mainly by the activity that is used for limiting the latch door bolt of gravity, is applicable to door, the window on the fixed object or the locking of the equipment of lid is arranged.Because the vehicle-mounted equipment of maybe can moving is in vibration and swinging condition all the time when transportation or carrying, so just cause the latch door bolt to come off easily and lose locking action, the unsafe condition that door, window or lid are opened can appear, simultaneously because vehicle-mounted space is all compared nervous, utilization of space is had relatively high expectations, and the latch volume that uses at present is all bigger, and installation and operating space are all bigger, can't satisfy vehicle-mounted requirements on transport.

The patent No. is 02262837.1 Chinese utility model patent, a kind of latch is disclosed, this latch is made of back seat, protecgulum and slotting door bolt, protecgulum covers on outside the back seat, protecgulum is provided with chute, an end sleeve of inserting door bolt is inserted fixing the pushing away of door bolt one side and is turned round and pass chute and cooperates with chute is movable in the door bolt hole of protecgulum, insert latch also be provided with about locating piece.The advantage of this utility model is the latch door bolt to be sealed be installed in the cavity volume of back seat and protecgulum formation; strengthened protection greatly to lock bolt; but because the locating piece location is unreliable up and down, push away to turn round being easy to from chute, come off, cause the danger that loses locking action.

The utility model content

In order to overcome the defective of prior art, the purpose of this utility model provide a kind of structure small and exquisite, anti-loose, have an automatic spacing function, latch that simultaneously can be bidirectionally limited.

The utility model is achieved by the following technical programs:

A kind of two-way from spacing latch, comprise latch base, latch door bolt, described latch base is provided with the pin tube, the middle part of described pin tube is provided with the gathering sill of sealing, described latch door bolt is slidably disposed in the described pin tube, the two ends of described gathering sill are provided with latch door bolt stopper slot symmetrically, and the middle part of described latch door bolt also is provided with flexible member.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid two-way from spacing latch, wherein said latch door bolt comprises latch body, horizontal latch handle at the latch body middle part, and the middle part of described latch body also is provided with the flexible member reference column.

Aforesaid two-way from spacing latch, wherein said latch door bolt stopper slot is vertically set on the two ends of described gathering sill homonymy symmetrically, and described latch handle card is inserted in the described stopper slot.

Aforesaid two-way from spacing latch, wherein said flexible member is a torsion spring, and described torsion spring set is contained in the flexible member locating slot on the described latch body, and the one end is fixed on the described latch body, and the other end is fixed in the described pin tube.

The utility model adopts the symmetrical structure design, effectively dwindled the appearance and size of latch, the latch of latch is latched in all extended locking the in two ends of plug housing, need not distinguish or installation form up and down, so just significantly reduced the kind of latch, be very easy to the manufacturing and the installation of latch, reduced the installing space of latch simultaneously.The utility model is suitable for various doors, window or the locking of the equipment of lid is arranged, when the latch door bolt slides into the position of latch door bolt stopper slot, the latch handle all can insert the latch at plug housing two ends automatically and fasten dead bolt in the stopper slot with a bolt or latch under the effect of torsion spring torsion, there is not external force to pull the latch handle, the latch handle can't break away from latch door bolt stopper slot, in the handling process of vehicle transport or equipment, can not lose efficacy like this owing to vibrations cause latch locking.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
