Description

A kind of detachable scaffold lock collar latch

Technical field

The utility model relates to a kind of link of scaffold, relates to a kind of detachable scaffold lock collar latch specifically, is widely used in the support of high lowrise construction, bridge, power station, sports palace building complex assembly unit scaffold.

Background technology

At present, the bracing frame of room finish, building operations or bridge construction adopts the lumps of wood as stressed support system usually, perhaps be connected and fixed built as bracing frame by steel pipe, brace, lock collar, latch, the connection of its bracing frame generally is that lock collar directly is weldingly fixed in the vertical rod, then by the cross bar socket by the screw bracing frame that is composed of a fixed connection.Even cross bar is provided with latch usually, it is up and down two pins, but pin is straight, without any radian.So, the deficiency of its existence is: 1. latch is provided with two pins up and down, causes the wasting of resources; 2. pin is straight, and any radian is not set, and connects firm inadequately when making the pin of latch pack the lock collar jack into.

Summary of the invention

In order to overcome the deficiency that now above technology exists, the purpose of this utility model be to provide a kind of simple in structure, structure firmly, easy accessibility, cheap, safe and reliable detachable scaffold lock collar latch.

The technical scheme that the utility model technical solution problem is adopted is: a kind of detachable scaffold lock collar latch, described latch comprises latch head and latch foot, it is characterized in that: the big opening of described latch head coincide symmetrically with cross bar and is connected, little opening of latch head and the vertical rod support that matches, described latch foot is provided with a depression arc by little opening one side.

The beneficial effects of the utility model are: not only simple in structure, store conveniently, and Stability Analysis of Structures, cross bar easy accessibility, increase work efficiency.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the perspective view of latch;

Fig. 2 is that perspective view is looked on the right side of Fig. 1;

Fig. 3 is latch user mode partial structurtes schematic diagrames.

Among the figure: 1. latch, 1a. latch head, 1b. latch foot, the big opening of 1c., the little opening of 1d., 2. cross bar, 3. sleeve, 4. snap close, 5. jack, 6. vertical rod, 7. bolt, 8. depression arc.

The specific embodiment

A kind of as shown in Figure 1, 2, 3 detachable scaffold lock collar latch, described latch 1 comprises latch head 1a and the 1b of latch foot, it is characterized in that: the big opening 1c of described latch head 1a coincide symmetrically with cross bar 2 and is connected, the little opening 1d of latch head 1a and vertical rod 6 support that matches, the described latch 1b of foot is provided with a depression arc 8 by little opening 1d one side.

During installation, the lock collar that on smooth ground, at first snap close 4 and sleeve 3 the is connected as one vertical rod 6 of packing into, and with bolt 7 lock collar is fixed in vertical rod 6.The big opening 1c and the cross bar 2 of latch 1 are welded to connect, it is fixing to link closely in the jack 5 that the 1b of latch foot on the cross bar 2 aligning insertion snap close 4 and sleeve 3 are formed then, the cross bar 2 that four jacks 5 can be packed into and be connected with latch 1, present embodiment cross bar that latch 1 connects two jacks 5 of packing into that draw are enough to explanation.Because latch foot 1b one side is provided with a depression arc 8, the little opening 1d of latch head 1a tightly props up vertical rod, and the 1b of latch foot opposite side tightly props up snap close 4 inboards, and therefore, latch 1 is comparatively firm with being connected of lock collar.Install by above method, lock collar installed by identical method, and then pack in the jack 5 of lock collar, install repeatedly with the method by the cross bar 2 that latch 1 connects by other vertical rod 6, forms one by real work need bracing frame.Damage need safeguard the time when occurring cross bar 2 in the use, the cross bar 2 that more renews after bolt 7 is backed out is reinstalled again, increases work efficiency.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.

Claims

1. detachable scaffold lock collar latch, described latch (1) comprises latch head (1a) and latch foot (1b), it is characterized in that: the big opening (1c) of described latch head (1a) coincide symmetrically with cross bar (2) and is connected, the little opening (1d) of latch head (1a) and vertical rod (6) supports that match, described latch foot (1b) is provided with the arc (8) that caves in by little opening (1d) side.
