Abstract

The utility model provides a novel welding hook. The novel welding hook comprises a hook seat and a hook body; a welding part is located at the bottom of the hook seat; the hook body is provided with a cambered bent section; one end of the cambered bent section is connected with the hook seat, while the other end of the cambered bent section extends downwards to form a straight section; a hook point is formed at the lower end of the straight; a hook mouth is formed by the hook point and the free end of the hook seat; the opening and the closing of the hook mouth are controlled by a bolt; the upper end of the bolt is hinged with the hook point, while the lower end of the bolt is in contact with the free end of the hook seat; the orthographic projection of the free end of the hook seat on the hook body is located in the middle of the hook body. The hook body is provided with the cambered bent section and the straight section, the orthographic projection of the hook point on the hook seat is located in the extension line of the length direction of the hook seat and the orthographic projection of the free end of the hook seat is located in the middle of the hook body, and the novel welding hook has the advantages that the length of the hook seat is reduced so that the length of the welding part on the hook seat is correspondingly reduced, and the weight of the hook seat and the workload of welding are reduced. The hook body is provided with the cambered bent section and the straight section extending downwards so that the hook body has a relatively large wrap angle, the bearing region of the hook body is increased and the stress direction range is expanded.

Description

A kind of Novel welding hook

technical field

The utility model relates to a kind of Novel welding hook.

background technology

Welding hook belongs to the wherein one of suspension hook, be applicable to bridge, building, mine, sea, shipbuilding, railway, chemical industry metallurgical, aviation, additionally arrange pipeline, on the mechanical equipment of the construction project such as highway, space flight, manufacture automobile, large part transport, harbour, venue and industry, as functions such as lifting, lifting, tractions.

As shown in Figure 1, existing welding hook comprises hook seat 1 and coupler body 7, weld is in hook seat bottom, bill and hook seat free end form the mouth of hook, the keying of the mouth of hook is controlled by dead bolt 5, the lower end of dead bolt is articulated with on hook seat free end, and upper end and the bill of dead bolt touch, and the orthogonal projection of bill on hook seat is positioned at the middle part of hook seat length direction.For this welding hook, in the time that stressed site of action is bill and dead bolt, while bearing obliquely pulling force, bearing capacity is little, and easily fracture exists and is subject to the little and safety hazard of force direction Applicable scope.The occupied cornerite of coupler body is little, is not easy to assembling and is connected.In addition, hook seat length is larger, causes that weight is large, cost is high, and causes the length of weld part larger simultaneously, and welding job amount is large.

summary of the invention

The technical problems to be solved in the utility model is to provide a kind of Novel welding hook, and its institute's holding capacity direction Applicable scope is large, and bonding area is little.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A kind of Novel welding hook, comprise hook seat and coupler body, weld is in hook seat bottom, and coupler body has curved bend tune, curved bend tune one end is connected with hook seat, the other end extends to form straight section downwards, the lower end that bill is straight section, and bill and hook seat free end form the mouth of hook, the keying of the mouth of hook is by dead bolt control, the upper end of dead bolt is articulated with on bill, and the lower end of dead bolt and hook seat free end touch, and the orthogonal projection of hook seat free end on coupler body is positioned at the middle part of coupler body.

Above-mentioned Novel welding hook, dead bolt bottom has recess, and hook seat free end has the boss that is positioned at dead bolt bottom recess in the time that hook seat free end is touched in dead bolt bottom.

Above-mentioned Novel welding hook, on bill, have hinged lug, accordingly, dead bolt upper end has the open slot that holds hinged lug, the hinged lug of dead bolt upper end and bill is realized hinged by elastic cylindrical pin, on elastic cylindrical pin, cover has torsion spring to realize the dead bolt automatic blocking mouth of hook.

Coupler body has curved bend tune and the straight section to downward-extension, the orthogonal projection of bill on hook seat is positioned on hook seat length direction extended line, orthogonal projection on hook seat free end is positioned at the middle part of coupler body, this structure has shortened hook seat length, also with regard to the corresponding length that has shortened weld part on hook seat, hook seat weight and welding job amount have been reduced.Coupler body has curved bend tune and the straight section to downward-extension, makes coupler body have larger cornerite, and the load region of coupler body increases, and expanded by force direction Applicable scope.Coupler body has the straight section to downward-extension, and the change of dead bolt setting and hand of rotation, the utility model is also had advantages of be simultaneously convenient to assembling and be connected.

brief description of the drawings

Below in conjunction with accompanying drawing to further detailed explanation of the utility model:

Fig. 1 is the structural representation of existing welding hook.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is the structural representation of dead bolt.

Fig. 4 is the lateral plan of Fig. 3.

In figure: 1 hook seat, 2 curved bend tunes, 3 straight sections, 4 weld parts, 5 dead bolts, 6 elastic cylindrical pins.

Detailed description of the invention

As shown in Figures 2 to 4, a kind of Novel welding hook, comprises hook seat 1 and coupler body, weld part 4 is positioned at hook seat bottom, coupler body has curved bend tune 2, and curved bend tune one end is connected with hook seat, and the other end extends to form straight section 3 downwards, bill is the lower end of straight section, bill and hook seat free end form the mouth of hook, and the keying of the mouth of hook is controlled by dead bolt 5, and the upper end of dead bolt is articulated with on bill, the lower end of dead bolt and hook seat free end touch, and the orthogonal projection of hook seat free end on coupler body is positioned at the middle part of coupler body.

In order to realize, dead bolt bottom and hook seat free end are stable to be touched, and dead bolt bottom has recess, and hook seat free end has the boss that is positioned at dead bolt bottom recess in the time that hook seat free end is touched in dead bolt bottom.

On bill, have hinged lug, accordingly, dead bolt upper end has the open slot that holds hinged lug, and the hinged lug of dead bolt upper end and bill is realized hinged by elastic cylindrical pin 6, and on elastic cylindrical pin, cover has torsion spring to realize the dead bolt automatic blocking mouth of hook.
