Utility model content
In view of the above problems, the utility model be intended to provide it is a kind of for face exhibition exhibition booth build without tool lock
Between, it can be achieved that the quick lock between display frame mounts and dismounts, it is easy to use, save a large amount of time and manpower, build material
Expect reusable, economizes on resources, there is higher environmental benefit.
To achieve the goals above, technical solution used by the utility model is as follows: the utility model discloses a kind of nothing
Tool latch fitting is cylindrical lock body in the middle part of latch fitting, is equipped with bolt in one end of lock body, the locking screw of adaptation is connected on bolt
Mother is equipped with a U-shaped opening in the other end of lock body；Equipped with overturning pressing plate and pin rod, overturning pressing plate is flexibly connected by pin rod
At U-shaped opening.
Further, the middle part of the overturning pressing plate is equipped with an open slot, and the pin rod is passed through from the top of open slot,
One end far from lock body on the pin rod inside open slot connects a spring, and the other end of spring is connected to a left side for open slot
Side bottom.
Further, nut locking is used after being pierced by U-shaped opening side in the pin rod both ends.
Further, one end far from lock body on bolt is equipped with longitudinal split pin perforation, on locking nut with open
Mouth pin perforates corresponding position equipped with the connecting pin bores being adapted to.
Further, the length of the overturning pressing plate is greater than the diameter of lock body.
Further, the diameter of the locking nut is greater than the diameter of lock body.
The beneficial effects of the utility model are:
The disclosed splicing and disassembly that can be realized using the structure of itself between exhibition frame without tool latch fitting of the utility model, is not necessarily to
Utilize other installation tools；And the structure of latch fitting itself is simple, use process is convenient and quick, and what sufficiently adaptation exhibition booth was built wants
It asks；The exhibition booth built using this kind of latch fitting will not leave behind trace on frame after disassembly, exhibition booth, which is built material and repeated, to be made
With effectively save resource has higher environmental benefit.

Specific embodiment
In order to make those skilled in the art be better understood on the technical solution of the utility model, below with reference to attached
Fig. 1-4 pairs of the technical solution of the utility model are further described.
It should be noted that embodiment provided by the utility model merely to the technical characteristics of the utility model into
The effective explanation of row, the left side, right side, upper end, lower end etc. position word merely to carrying out to the utility model embodiment
Preferably description, is not to be regarded as being the limitation to technical solutions of the utility model.
It builds to solve exhibition booth in the prior art and takes time and effort, building material cannot reuse, serious waste of resources
The problem of, the utility model discloses a kind of no tool latch fitting, this is suitable for the modular showing frame being adapted to the latch fitting without tool latch fitting
The connection of frame is built, the concrete mechanism of the no tool latch fitting are as follows: in the middle part of latch fitting is cylindrical lock body 1, in display frame 9
The medium position of each edge is equipped with the preformed hole 10 being adapted to lock 1 diameter of body, bolt 2 is equipped in one end of lock body 1, in bolt 2
The locking nut 3 of upper connection adaptation is equipped with a U-shaped opening 4 in the other end of lock body 1, and overturning pressing plate 7 passes through 5 activity of pin rod
It is connected at U-shaped opening 4,5 both ends of pin rod are locked after being pierced by 4 side of U-shaped opening with nut 6, and pin rod 5 is matched with nut 6
It closes using the disassembly for being not only convenient for part but also improves the stability of connection；
The diameter of the locking nut 3 is greater than the diameter of lock body 1, and the length of the overturning pressing plate 7 is greater than the straight of lock body 1
The specific size of diameter, locking nut 3 and overturning pressing plate 7, which designs, can avoid latch fitting under locking state and shuttles in preformed hole movement.
The middle part of the overturning pressing plate 7 is equipped with an open slot 8, and the pin rod 5 is passed through from the top of open slot 8, is in
One end far from lock body 1 on pin rod 5 inside open slot 8 connects a spring 12, and the other end of spring 12 is connected to open slot 8
Left side bottom.
One end far from lock body 1 on bolt 2 is equipped with longitudinal split pin perforation 11, on locking nut 3 with split pin
11 corresponding positions perforate equipped with the connecting pin bores being adapted to.
In use, when original state, overturning pressing plate 7 presses to lock first by the preformed hole 10 on adjacent display frame 9 to it
1 direction of body (as shown in Figure 2), spring 12 are in relaxed state, then allow lock body 1 to sequentially pass through pre- on adjacent display frame 9
It boxes out 10, makes its overturning to the prominent lock body in the position vertical with lock body 1 and two sides after overturning pressing plate 7 and entirely passing through preformed hole 10
1 position is adjacent to frame, and spring is in the state that tensioning stretches at this time, and then screwing locking nut 3 makes frame and tight, nut
After tightening, by split pin out of, connecting pin bores insertion bolt tail split pin perforation 11, and split pin tail portion is pulled open, prevented
Locking nut 3 and bolt 2 relatively rotate；Split pin is taken out when disassembly first, then unscrews locking nut 3, body 1 will be locked to overturning
A distance is moved in 7 side of pressing plate, and overturning pressing plate 7 turns again to the position for pressing to lock body 1 under the action of spring-return convergent force
It sets, latch fitting can be taken out out of frame at this time；Overall structure without tool latch fitting disclosed in the utility model is simple, operates with fast
Speed it is convenient, it can be achieved that between frame material without the self-locking connection of tool, sufficiently meet exhibition booth builds requirement；It is connected using the latch fitting
Exhibition booth frame will not leave the marking on frame, and frame is reusable, economize on resources, and have preferable environmental benefit.
The basic principles and main features and advantage of the utility model have been shown and described above.But the foregoing is merely
Specific embodiment of the utility model, the technical characteristics of the utility model are not limited thereto, such as: pin rod and U-shaped opening side
The connection type of wall can also directly tight fit be connected etc.；Therefore any those skilled in the art is in the skill for not departing from the utility model
The other embodiments obtained under art scheme should all cover among the scope of the patents of the utility model.
