Abstract

The utility model relates to an improved lock bar for a container door. A lock head is a cylindrical pin head part connected with two bi-directional opposite notch structures each of which is formed by a pair of short teeth, wherein, the top surface of each of the two relatively shorter teeth is convexly provided with a convex body surrounding each of the shorter teeth. A lock seat is composed of a vertically H-shaped lock block and a pyramidal stand-shaped position block which are connected with both ends of a base. The bottom surface of the base is flat, having a length larger than the outlines of the lock block and the position block. Each of a large lining and a small lining forms an integrally half to half split type. Both sides of each of the linings are provided with upward extended stop flanges which are matched with positioning holes on the corresponding positions of a big and a small brackets in order to realize the axial position for the lining. The utility model can be provided with relatively weak force and can improve security in the way of freight transportation, being very convenient for replacing parts when a container is repaired.

Improvement structure of the present utility model describes in detail in the technical scheme of preamble narration realization goal of the invention in conjunction with the accompanying drawings, repeats no more herein.Wherein: handle, bearer carrier, bay cover, cup-shaped lining, spacing ring can use prior art, and this manual does not describe in detail.

Design feature of the present utility model:

1. novel tapered end has increased the amount of movement of locking bar central axis, and supports by means of the lock head, utilizes lever principle, makes the operator can be with less power breakdown door, and makes crack between a door and its frame open greatlyyer.

Tapered end, the designer has set up two bossy bodies at the end face of former tapered end two short teeth, when opening the door operation, please refer to Figure 12 Figure 13, the handle half-twist, make chamber door obtain one and open space B, behind the handle Rotate 180 °, please refer to Figure 14, two bossy bodies of tapered end contact with the lock header planes, make chamber door obtained one increase open space C, so just make chamber door under the situation of using less power, obtain the crack between a door and its frame bigger, particularly when crack between a door and its frame by ice-bound live the time, by means of flange than former design, make chamber door obtain a unlatching moment that increases, can break ice-bound comparatively effortlessly.

2. former lock is improved, change lock lower die line position, make the profile of its length greater than lock dog and locating piece, one of lock dog bottom surface side is the ladder polyline shaped, thereby make the lock bottom obtain a bigger plane, can reach steady, convenient during installation, simultaneously, increased the welding penetration with door-plate, made welding quality more reliable.

Lock has moved 6mm with lock bottom loft to minor face, has formed the polyline shaped loft, and such change makes the bottom more smooth, and lock is installed more easy, reliable, has increased welding penetration, can improve welding quality.

3. be improved to the whole division of half and half formula by the big or small bearing insert with door lock assembly, cancel pad part in the large and small carriage, it is more easy that large and small bearing is installed.

Large and small carriage lining is upper and lower two halves formula lining originally, in establish pad in the large and small carriage, now lining is changed into whole division of half and half formula lining, cancelled pad part in the large and small carriage, in order to prevent moving axially of lining, the lining both sides are provided with the stop flange that protrudes upward, cooperate with the locating hole of Big bracket relevant position, can prevent effectively that lining from axially skidding off, make large and small bearing simple installation after changing whole division of half and half formula lining into, reduced the locking bar part, also can improve and install and production efficiency.

Trapezoidal Big bracket, this part has adopted trapezoidal design, fixes the whole division of half and half formula lining that matches with it with two stop flange, makes it unlikely axially outer sliding.

Because this Big bracket size is longer, it can bear bigger active force, can provide bigger power to compress an envelope in other words, can be used as the locking bar bearing of refrigerating box.

4, the 14-17mm that extended of the spanner seat height dimension after the improvement, its effect is that handle can not skid off, and prevents chamber door by wrongful unlatching, has improved the safety in the freight transportation way after the rivet that connects handle and spanner seat damages or destroyed by illegal person.

Spanner seat height dimension after the improvement 14-17mm that extended, make spanner seat overall height rise to 69mm, after the spanner seat is increased, after the rivet that connects handle and spanner seat damages or artificially damaged by original 50mm, handle still can not skid off from the spanner seat, and chamber door still can not be opened.Can prevent that like this chamber door from being opened wrongly, improved the safety of freight transportation.

5. locking bar of the present utility model can exchange with other general locking bar part, and renewal part was also very convenient when container was repaired.
