In addition, it should be noted that, attached drawing referred herein is in order to illustrate the need with explanation the embodiment of the present invention
It wants, the connection between the shape of each component that attached drawing is embodied, size and different components is used only for schematically illustrating
The embodiment of the present invention does not constitute the limitation to protection scope of the present invention.
With reference to attached drawing 1-2, a kind of lifting platform truck self-reducing resisting device of the invention, total inventive concept is as follows, including
Platform body frame 1, the lock 4 being used cooperatively with the lock tooth 3 on bolt 2, connect two at the bolt 2 being mounted on platform body frame 1
The connector 6 of platform truck supporting leg 5, the rope 7 connecting with the lock 4, the rope being mounted on the platform body frame 1 manipulate
Mechanism 8.
The end of the lock 4 is articulated with the connector 6, and the front end of the rope 7 is connect with the lock 4, rear end
It is connected to the rope operating-controlling mechanism 8.The rope operating-controlling mechanism 8 manipulates the rope 7 and the lock tongue 9 of lock 4 is driven to limit
It lock on the lock tooth 3 of the bolt 2.
The lifting platform truck self-reducing resisting device in a kind of embodiment, the self-reducing resisting are discussed in detail below by attached drawing 4
Device is provided with bolt 2, and the bolt 2 is in long strip, is installed on platform body frame 1.It is provided on the bolt 2 and continuously to arrange
Tooth 3 is locked, lock tooth 3, next to arrangement, accords with the locking of platform truck different height along the length direction of bolt 2.Wherein lock tooth 3
Cross section include the inclined wall 10 being connected and vertical wall 11, form acute angle between the inclined wall 10 and vertical wall 11.
Such as in attached drawing 2,4, the left side of vertical wall 11 is arranged in the inclined wall 10, and the lock tongue 9 of the lock 4 of self-reducing resisting device is then at this time
It is formed with the limiting locking arm 12 to match with vertical wall 11 and the inner wall being oppositely arranged with inclined wall 10 13, limiting locking wall
12 and inner wall 13 lock tongue 9 has been interconnected to form in bottom.The rope operating-controlling mechanism 8 of self-reducing resisting device is then set at this time
It sets on the left side of bolt 2.Certainly, vertical wall 11 is arranged in the embodiment on 10 left side of inclined wall, rope manipulates machine at this time
The right of bolt 2 is then arranged in structure 8.
In the embodiment that attached drawing 1-4 is shown, the connector 6 is being controlled to connect two ipsilateral platform truck supporting legs 5
After the operation of connector 6 processed, it is just able to achieve the operation of two platform truck supporting legs 5.It is away from each other on the lock 4 with lock tongue 9 at this time
Rear end is then hinged on the connector 6, while the front end of the rope 7 is then connected to the front of lock 4, i.e., close to lock tongue
9 position.In the present embodiment, the latch design is at opposite 4 ontology bending state of lock, and certainly, bending angle is smaller,
It is realized by orthodrome changeover portion in bending state.To realize that rope 7 by smooth conducting operation, is pulled out from the front of lock 4
Rope 7 conducting operation is also then carried out by guide wheel 14, which is provided with conductance slot and passes through for rope, the peace of guide wheel 14
On support arm 15, and support arm 15 is then according on connector 6.In this embodiment, preferably cylindrical structure manufactures connector 6
It forms, and the then good cable wire of preferred durability of rope 7.
For the rope operating-controlling mechanism 8 that attached drawing 3 is shown, in this embodiment, the rope operating-controlling mechanism 8 includes installation
Manipulation frame 16, lower end rotation on platform body frame 1 are fitted to the manipulation slot 17 of manipulation frame 16 and upper end stretching manipulation frame 16
Manipulation handle 18.The rear end of the rope 7 is connected to the manipulation handle 18, and the manipulation slot 17 includes the opening groove of connection
Hole 19 and locking slot 20.Reset spring 21 is connected between the manipulation frame 16 and manipulation handle 18 to realize to manipulation handle
18 reset.
In this embodiment, the unlatching slot 19 is arc-shaped slot, and the locking slot 19 is strip slot, and institute
Arc-shaped slot is stated to connect with the front end of strip slot.
The manipulation handle 18 includes up knob 22 and lower rotational segment 23, and the up knob 22 hingedly connects with lower rotational segment 23
It connects, to realize that up knob 22 is put relative to the lower rotation of rotational segment 23 into the unlatching slot 19.
In some embodiments, the manipulation frame 16 is designed to the box body shape of side opening, and roof is to be arranged manipulation slot 17
It stretches out with for manipulation handle 18 to implement to operate.Hinged installation of the side plate for manipulating handle 18 below, front front side board
Then removal is for the convenient installation of each component.
When needing to open platform truck (full name is lifting platform truck, herein for referred to as), operation manipulation handle 18 is located at institute
It states and opens in slot 19, rope 7 pulls lock 4 to exit lock tooth 3 at this time, and platform truck can be freely lifted operation.
When needing to lock, that is to say, that after platform truck has reached required height, the handle 18 of operation manipulation at this time is located at
In the locking slot 20, in the process, reset spring 21 acts on manipulation handle 18, so that manipulation handle 18 resets, together
When with rope 7 connect lock 4 fallen in corresponding lock tooth 3 under the action of self-weight, realization platform truck supporting leg 5 locking, guarantor
Entire platform truck is held in stable height.
The embodiment of the present invention is described in detail with reference to the accompanying drawings above, it should be noted, however, that above-described embodiment
For illustrating rather than limit the present invention, and those skilled in the art will design many alternate embodiments and simultaneously
Without departing from scope of the appended claims.In the claims, word " comprising " is not excluded in addition to cited in claim
Those of except element or step presence.Word "a" or "an" before element does not simultaneously exclude such element
Presence.Certain features are documented in the pure fact of this in mutually different dependent claims and are not meant to these features
Combination cannot be advantageously used.
