Abstract

Disclosed is a stand for a Christmas tree, which is mainly composed of a base, a cover casing, a ratchet and detent mechanism and a drive mechanism using wire ropes, wherein, the ratchet and detent mechanism utilizes double detents, and the drive mechanism using wire ropes utilizes a multirope structure of one ratchet for one rope. Additionally, because an operating handle is provided with a supporting claw with a detent for manual control, a lock pin and a padlock hole, a method of double locking can be used for ensuring the relative position of the supporting claw and the operating handle; thereby, the speed and the safety of the clamping operation are enhanced. The utility model has the advantages of reasonable structure, convenient operation and good hand feeling and can replace the prior base of a Christmas tree, with no risk at all.

Description

The Christmas tree mounting

The utility model relates to the pedestal articles for use, particularly a kind of clipping pedestal or stand apparatus.

The existing mounting that is used for the Christmas tree pedestal is made up of pedestal, case, vertex (vertices) and a clamping device, be provided with three or four pinch pawls,, steel wire rope tightened up by crank rotating ratchet axle by a long steel wire rope serial connection interlock control, " tree " erects, and its base portion clamping is fastened on the mounting.Simple in structure, convenient but operation is owed, hard time-consuming sense is often arranged.

The purpose of this utility model is that improved a kind of clipping Christmas tree mounting will be provided, than convenient to operation, safe and reliable before improving.

This Christmas tree mounting mainly is made up of pedestal, case, vertex (vertices) and clamping device, and clamping device comprises a ratchet and pawl arrangement and a wire cable transmission mechanism, it is characterized in that said ratchet and pawl arrangement is the ratchet and pawl arrangement that is provided with dual ratchet; Said wire cable transmission mechanism is the fast speed driving mechanism of a pawl one rope formula.

Wherein ratchet in the ratchet and pawl arrangement and lever are linked together, the front end cladding ratchet increment of lever, and be provided with an inclined-plane; Be provided with in the spindle clamp of lever one by finger hold control, head has the support claw of ratchet.

Wherein a pawl one rope formula wire cable transmission mechanism is four rope formula transmission mechanisms, and wire rope end is provided with the crimping dop, and the one head is hinged with on pedestal, and the centre is worn and connected pinch pawl and guiding sheep eye thimble, and the other end compiles in the axocoel that is fixed on ratchet shaft (wall).

The lever of said ratchet is provided with the lock pin and the lock pin groove of locking usefulness, and its position is corresponding with the qualification position of support claw; Also be provided with locking on the said support claw and use lockhole, its position is corresponding with the qualification position of lever, and both constitute dual fail-safe locking mechanism.Good effect of the present utility model is:

1, adopted two ratchet ratchet and pawl arrangements, new reasonable, good hand touch, safety and steady, the structure of pressing the up and down operation that can also tramp with one's feet;

2, the wire rope rope of Cai Yonging is made with flexible wire ropes-Unite States Standard " MlLW83420D " by the airplane operation system, and transmission is respond well, and four rope-like structures (pawl one rope) can shorten stroke, improve clamp operation speed;

3, being provided with than single ratchet one deck of having Duoed of two ratchets set up defences, and in fact improved security, and other adds safety lock mechanism, and it is perfectly safe to accomplish, stops unsafe factor, ensures the well atmosphere of celebrating joyously red-letter day.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the ratchet and pawl arrangement schematic diagram.

Referring to accompanying drawing.Embodiment shown in Figure 1 is a Christmas tree mounting with two pawl ratchet ratchet clamp mechanism of four rope formulas of four pinch pawls.Pedestal 1 is that the centre that a bottom surface is a hexaplanar is provided with cup base of seat.Can contain the usefulness of low amounts of water in the handleless cup seat, and be provided with the small-sized vertex (vertices) 5 of location usefulness as maintenance.Being buckled with a case 2 above, leaves a blank and is convenient to insert the butt of tree in the centre.Around four pinch pawls 4 enclosed and stand, the foot rest at its rotating shaft place was fixed together with the handleless cup seat.The two ends that pinch pawl 4 leaves rotating shaft respectively are provided with a hole, the hole of pawl end is used for connecting steel wire rope 6, each pinch pawl draws with steel cable separately, and be installed in handleless cup seat along the limit by the sheep eye thimble symmetry of guiding usefulness, and an end of its steel wire rope is fixed, the other end then is pooled on the internal chamber wall of ratchet shaft together, can reach synchronously and tighten up.A hole of pinch pawl 4 pawl tails is used for fixing extension spring 20, and the installment state of extension spring 20 is a rectangle, is used for producing the power that pinch pawl 4 loosens resilience.The pawl end of pinch pawl 4 also can change establishes arc movable claw, i.e. front 2 contacts up and down, and the protrusion position activity riveting of back and pawl end connects, and effect is similar.The 3rd, the decoration edge on the case, the 7th, compile the sheep eye thimble that steel wire rope is used, the 19th, the plate framework of clamp mechanism is installed, plate framework and pedestal are fixed together.Clamp mechanism includes ratchet 22, and ratchet shaft 16, lever 12, foot pedal 11, the support claw of support claw 13 and interior dress reset with stage clip 10.The front end cladding ratchet increment of lever 12, and have a transitional inclined-plane of making pushing tow pawl axis 17.The side of lever 12 rear ends is provided with lock pin 23, and it can promote along the lock pin groove, and support claw is carried out limit-type locking.Limited support claw 13 links to each other with lever 12 by rotating shaft 9, and the rear end of support claw 13 is provided with the usefulness of lockhole 21 for padlock 14 lockings.The coadaptation of twice latched position phase makes it and can lock simultaneously, forms the twice insurance then.The axial trough at pawl axis 17 places and retainer spring 18 all are located at the both sides of plate framework 19.Pawl axis 17 is subjected to lever 12 controls, contacts with end face, the inclined-plane of its front end when being applied.The 8th, lever power on reset power assistant spring.

The course of work of the utility model mounting is summarized as follows:

As shown in Figure 1, the silver birch branch about 10 centimetres is put in 4 settings of pinch melon into, (also can other shaft of clamping) presses lever 12 downwards, drives ratchets 22 by its support claw 13 and rotates, make each two of length totally four steel wire ropes 6 strain synchronously, drive four pinch pawls 4 motion and tighten up, note sitting positive branch when beginning to contact the branch surface, press lever then repeatedly, steel wire rope is constantly strained, rapidly the branch butt is clamped, so obtain to support.Extension spring 20 is extended thereupon.When loosening operation, the lever 12 of holding with a firm grip, the ratchet 16 of support claw 13 front ends is freed for it, upwards move degree more than 50 then, this moment, inclined-plane, the end face of lever front end successively contacted pawl axis 17, and with its top from and throw off the ratchet increment, under the elastic force effect of extension spring 20, make the ratchet shaft counter-rotating, steel wire rope unclamps, and pinch pawl 4 just leaves recovery.
