Description

A kind of latch hook

Technical field

The invention belongs to draw lockset, specifically belong to a kind of latch hook.

Background technology

Material-uploading style has many kinds, and wherein stack pallet is connected with lifting turning mechanism, then by lifting turning mechanism to giving The direct discharging of truck is also one of which.This kind of material-uploading style is compared for other, efficiency high, is saved artificial.But it is this on Material mode needs stack pallet being connected with lifting turning mechanism, and existing connected mode is the directly interspersed connection of bearing pin, troublesome in poeration It is and unreliable.

Application number：A kind of 200680049012.7 automobile door locks proposed, its principle are described clamp and pallet difference It is installed on by bearing pin in structure case, there is air inlet structure case side, and pinning enters structure case air inlet and clamp is acted on so that clamp Rotate counterclockwise around the shaft, constrained when clamp rotates to ad-hoc location by pallet, only release constraint of the pallet to clamp, card Son can just turn clockwise, and this principle can fetter the similar pinning object into structure case air inlet automatically, with lifting Material field can save operation step, and reduction manually latches time-consuming and unsafe problem that easily malfunctions, but by its structure Need to do following improvement to the practical application of the principle used in lifting feeding field：

1, waste of material, unreasonable structure bears that strength is larger for lifting feeding, the body of simple ratio increase clamp and pallet Manufacture into waste of material；

2, safety, when pinning is not bound, the pinning on stack pallet should skid off before ground is left, it is ensured that be turned in lifting Safety in journey；

3, durability, pinning is exerted a force to clamp during feeding, and clamp exerts a force to pallet, and deformation is squeezed at clamp and pallet constraint Or constraint is easily caused to fail or can not unmuzzle after abrasion；

4, practicality, should solve the high and low position change relative with structure case air inlet of the pinning on skip car and cause pinning to enter Air inlet；

5, convenience, after feeding is constructed, the constraint released to pinning should be facilitated.

The content of the invention

The invention aims to solve shortcoming present in prior art, and a kind of latch proposed is linked up with.

To achieve these goals, present invention employs following technical scheme：

A kind of latch hook, including hit hook, hit hook lock, ratchet, plate of unlocking, hit hook axle, lock shaft and support, the support is by two The framework that individual supporting plate and two laths with digital " 7 " shape breach surround, there is on the breach of supporting plate plate face tiltedly along, plate Edge and plate face horizontal stroke edge are erected in face, and the plate face on supporting plate is tiltedly along being inclined sliding surface, and when not buckling successfully, stack pallet can be suitable Inclined sliding surface to retreat, also have lower opening and upper hole on supporting plate；The support is provided with two slide bars；The hook that hits has a hook Mouth, hook-bill are the groove of a question mark shape, are lower hook lip below hook-bill, and the pressure effect of lower hook lip and stack pallet shackle can make Hook is hit to internal rotation, the above is lip of rising to the bait, and raised lip edge of rising to the bait is provided with the outside of lip of rising to the bait, and hits and also has hook axis hole and hook side on hook Hole, bearing pin is interspersed with hook side opening, the bearing pin also extends through one end of ratchet joining beam；Shaped like " Jiong " word, upper end is the hook lock that hits It is domatic, buckle under state, the domatic lip of rising to the bait with the outside of lip of rising to the bait is along engaging, and there is pin-and-hole lower end, and bottom is provided with spine tooth, hits hook lock Also equipped with the spring acted on upwards；The ratchet is furnished with ratchet spring, and ratchet spring makes ratchet tooth and spine tooth pair on ratchet It should engage, ratchet both ends are respectively provided with pin-and-hole, have ratchet bearing pin to intert in a pin-and-hole, have joining beam bearing pin to wear in another pin-and-hole Insert, ratchet passes through ratchet bearing pin and unlocking plate hinge connection；The unlocking plate is the plate for being similar to tadpole, and there are macropore, rear end in front end There is aperture, ratchet bearing pin is interspersed with aperture；The ratchet upper end is connected by joining beam bearing pin with ratchet joining beam, ratchet joining beam Connecting hole is elongated hole, and joining beam bearing pin is interspersed with elongated hole；The hook axle that hits sequentially passes through the upper hole of a supporting plate, hit on hook The upper hole of hook axis hole, another supporting plate；The lock shaft sequentially pass through the lower opening of a supporting plate, the pin-and-hole for hitting hook lock lower end, The macropore of unlocking front edge of board, the lower opening of another supporting plate.

Latch hook as the aforementioned, two slide bars are fixedly connected with support and two slide bars are by sliding sleeve and by on-hook Frame is slidably connected, or, slide bar is connected by sliding sleeve with bracket slide and two slide bars are fixedly connected with by on-hook frame, and support can Fluctuated with relative by on-hook frame.

Latch hook as the aforementioned, described hit are additionally provided with stopping means on hook lock, hook lock bullet under the action of the spring is hit in limitation The height risen.

Latch hook as the aforementioned, the Support frame inside, which also has, hits hook spring.

Latch as the aforementioned is linked up with, and adjustment joint is also installed with the supporting plate, is adjusted and is fixedly mounted on joint There is stay wire tube, have bracing wire in stay wire tube and bracing wire connects with unlocking plate.

In the present invention, latch hook employs the groove hook-bill of inclined sliding surface and the question mark shape on supporting plate, feeding Car collision latch hook buckle, does not fasten that stack pallet automatic backing is easy to use, guarantee buckles the security and fluency of feeding； Support relative can be fluctuated by slide bar by on-hook frame, and occurring in stack pallet shackle position still can be fast after height changes Speed mutually buckles with hook, practicality and strong applicability；The pressure effect of lower hook lip and stack pallet shackle can make to hit hook to internal rotation, Under the action of the spring, it is domatic to be engaged with the lip edge of rising to the bait for lip of rising to the bait, realize that machine automatization button is hung, automatic lockout, lifting upset During security；Stay wire tube is installed with the adjustment joint of use, has bracing wire in stay wire tube and bracing wire and a unlocking plate Connection, hit hook lock and original position latch hook is reset in the presence of spring and stopping means without operation bidirectional, open automatically Hook, conveniently unmuzzle.Total safely and efficiently solves the problems, such as that stack pallet carries out discharging by lifting turning mechanism, Loading efficiency is improved, simplifies operating procedure, durability is strong, simple in construction, and maintenance cost is relatively low.
