Abstract

The utility model relates to an elastic tube clamp of an umbrella rib, which is particularly suitable for a large beach umbrella. The tube clamp is clamped on an umbrella rib and is hinged with the end of a supporting rib of the umbrella, and the umbrella can be unfolded and folded. The tube clamp is composed of a convex ear with a through hole, and a clamp board which are fixed on a clamp surface. The tube clamp also comprises an elastic device composed of an elastic buckle with a spring, and an elastic buckle seat, and the elastic device is arranged on the clamp surface. The pipe clamp is fixed on the umbrella rib by screws, and one end of the spring tightly clings to the umbrella rib. When the umbrella is put up, the elastic force of the spring can spring the elastic buckle, and a pipe sleeve of a supporting rib gets the loosing force, and a gap between the pipe sleeve and the pipe clamp is increased. The umbrella is convenient to quickly put up with labour saving, and the tube clamp is suitable to umbrellas in various types.

Description

The umbrella frame Elastic tube clamp

The utility model relates to the part on a kind of en-toutcas, and suitable especially the use on large-scale parasols is clamped on the umbrella frame, and with the pipe box hinge joint of an epiphysis of umbrella, thereby realize strutting and drawing in of umbrella.

After the pipe box hinge joint of the pipe clamp on the existing large-scale parasols and a umbrella frame and an epiphysis, the gap between each part is less, rotates dumbly, and it is difficult therefore to open an umbrella, and often spends a lot of times ability that umbrella is strutted sometimes.

The purpose of this utility model is to provide a kind of umbrella frame Elastic tube clamp, installs securely on the ground umbrella frame, and can conveniently, rapid, effortless unfurl an umbrella.

The utility model is achieved in that the umbrella frame Elastic tube clamp is made up of the lug and the grip block that are fixed on the band through hole on the clamping face, also comprise and being installed on the clamping face, in a upper and lower snap-on seat that communicates, snap-on is installed, an end of mounting spring again in the snap-on, the end in addition of spring is close to the elastic device that constitutes on the umbrella frame.

Fig. 1, structural representation of the present utility model.

The left view of Fig. 2, Fig. 1.

Fig. 3, the utility model and pipe box, fulcra, umbrella frame connection diagram.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Clamping face (2) on have the rectangular surfaces of through hole, the both sides of the edge of upper surface mid portion respectively to have one to be parallel to each other and with the lug (3) of through hole (4), there is a little inclined-plane (5) lug (3) madial wall upper end for ease of cooperating with protruding axle (11) on the pipe box (10).

The lower surface both sides of clamping face (2) respectively have one, and to be the angle of inclination with clamping face (2) be 80～85 ° grip block (1).

One end of clamping face (2) has the upper and lower snap-on seat (8) that communicates, and the inside is equipped with

The snap-on of type (7), an end of the interior mounting spring of snap-on (7) (6), the end in addition of spring (6) is close on the umbrella frame (9), constitutes elastic device.

During use, two grip blocks (1) on the pipe clamp are clamped on the both sides of umbrella frame (9), and are fixed on the umbrella frame (9) with two screws.Two columniform protruding axles (11) on the pipe box (10) of fulcra (12) one ends are pressed in the through hole (4) on the lug (3) by the inclined-plane (5) on the lug (3) respectively, and to make pipe box (10) be the center with the through hole (4) on the lug (3), freely rotates on pipe clamp.When umbrella strutted, the elastic force of spring (6) outwards ejected snap-on (7), makes the pipe box (10) of fulcra (12) be subjected to a power of unclamping.Snap-on when closing one's umbrella (7) is pushed back snap-on seat (8).

The utility model is compared with prior art: because of the clamping face at pipe clamp increased by one simple in structure Elastic device when umbrella support is opened, is ejected snap-on by elastic device, gives fulcra, power of unclamping of pipe box, Gap between pipe box and pipe clamp is increased, facilitate rapidly like this umbrella support is opened, the leicht fallen D/A that therefore opens an umbrella, suitable Should use by various dissimilar umbrellas.

Claims

1, a kind of umbrella frame Elastic tube clamp, form by lug (3) that is fixed on the band through hole (4) on the clamping face and grip block (1), it is characterized in that also comprising and be installed on the clamping face (2), in a upper and lower snap-on seat (8) that communicates, snap-on (7) is installed, an end of mounting spring (6) again in the snap-on (7), the end in addition of spring (6) is close to umbrella frame (9) and goes up the elastic device that constitutes.

2, umbrella frame Elastic tube clamp according to claim 1, it is characterized in that clamping face (2) on the rectangular surfaces of through hole is arranged, the both sides of the edge of upper surface mid portion respectively have one to be parallel to each other and with the lug (3) of through hole (4), there is a little inclined-plane (5) lug (3) madial wall upper end, the lower surface both sides of clamping face (2) respectively have one, and to be the angle of inclination with clamping face (2) be 80～85 ° grip block (1), one end of clamping face (2) has the upper and lower snap-on seat (8) that communicates, and the inside is equipped with The snap-on of type (7).
