Description

Technical Field

[0001] The invention relates to the technical field of umbrellas, and in particular to an umbrella capable of preventing rib tension wires from breaking. Background Art

[0002] Umbrella is a common tool in daily life, mainly used for sunshade or shelter from rain and snow. It consists of a handle, ribs, umbrella cover and other parts, usually made of ductile fabric, frame material and winding wire.

[0003] ‌The rib cable of an umbrella (also called rib cable, skeleton connection cable or tension cable) is a key transmission component in the umbrella structure. It is responsible for connecting the joints of the ribs and controlling the opening and closing and support of the umbrella. The rib cable is a high-strength wire, usually made of nylon, polyester, metal wire or composite materials. It runs through the ribs and links the rib joints through tension, allowing the umbrella to open smoothly and maintain a stable shape.

[0004] When you open the umbrella with force or use it in strong winds, the ribs open instantly or the umbrella is bent by strong winds. The ribs and guy wires are subjected to the sudden tension in a very short time. At this time, the guy wire cannot buffer the generated tension, causing it to break easily. Summary of the invention

[0005] The purpose of the present invention is to provide an umbrella capable of preventing the breakage of the rib tension wire in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an umbrella capable of preventing rib pull wires from breaking, comprising an umbrella middle rod, a sliding sleeve slidably arranged on the umbrella middle rod, and umbrella ribs respectively hingedly arranged between the umbrella middle rod and the sliding sleeve, the umbrella ribs comprising a main umbrella rib hingedly arranged at one end at the upper end of the umbrella middle rod, a supporting umbrella rib hingedly arranged between the other end of the main umbrella rib and the sliding sleeve, a secondary umbrella rib hingedly arranged at the other end of the main umbrella rib, an outer umbrella rib hingedly arranged at one end at the other end of the secondary umbrella rib, a connecting rod at one end arranged on one end of the secondary umbrella rib, and a connecting pull wire at one end hingedly arranged at the other end of the connecting rod and the other end of which is connected to the other end of the outer umbrella rib. The connecting pull wire comprises a first wire body with one end hingedly arranged at the other end of the connecting pull rod; A second wire body having one end arranged at the other end of the outer rib; A connecting block disposed between the other end of the first wire body and the other end of the second wire body; A sliding opening formed on the connecting block; Two sliding blocks that can be slidably arranged on the connecting block and located within the sliding opening, and the two sliding blocks are respectively connected to the other ends of the first wire body and the second wire body Two wire passing holes respectively opened at the left and right ends of the connecting block and communicating with the sliding opening, the two wire passing holes are in clearance fit with the first wire body and the second wire body, and the first wire body and the second wire body respectively pass through the wire passing holes and are fixedly connected to the two sliding blocks; An elastic reset member arranged between the two sliding blocks.

[0007] Further improvement is that: two inclined openings are symmetrically opened on the connecting block, the two inclined openings are respectively communicated with the sliding opening and the wire passing hole, and chamfered surfaces are arranged at the ends of the two sliding blocks close to the inclined openings.

[0008] Further improvement is that: the elastic reset member includes an elastic connecting rope respectively arranged between the two sliding blocks and located within the sliding opening, and at least one elastic sphere arranged on the elastic connecting rope.

[0009] Further improvement is that: a filling inner cavity is opened on the elastic sphere, and a polyurethane foam layer is arranged within the filling inner cavity of the elastic sphere.

[0010] Further improvement is that: an auxiliary block is arranged on the sliding block, an auxiliary opening is opened on the auxiliary block, an elastic ball block is arranged within the auxiliary opening of the auxiliary block, a connecting rope is arranged between the elastic connecting rope and the elastic ball block, an auxiliary rope hole is opened on the auxiliary block, the auxiliary rope hole is communicated with the auxiliary opening, and the connecting rope passes through the auxiliary rope hole and is connected to the elastic ball block.

[0011] Further improvement is that: the sliding opening runs through and is opened on the connecting block, the sliding opening is opened along the length direction of the connecting block, two guiding grooves are opened on the connecting block, the guiding grooves are communicated with the sliding opening, the two guiding grooves are respectively opened on the upper and lower sides of the sliding block, and guiding blocks are respectively arranged on the upper and lower end faces of the two sliding blocks, and the guiding blocks are in clearance fit with the guiding grooves.

[0012] Further improvement is that: wire connecting grooves are respectively opened on the two sliding blocks, threaded grooves are opened on the side end faces of the two sliding blocks, the lower end of the threaded groove is communicated with the wire connecting groove, the wire connecting groove is in clearance fit with the first wire body and the second wire body, and a butt bolt is threadedly connected between the sliding block and the limiting plate, and the butt bolt is threadedly connected within the threaded groove.

[0013] After adopting the above technical solution, the beneficial effects of the present invention are as follows: When opening the umbrella with great force or using the umbrella in strong wind weather, when the connecting drawstring bears a suddenly applied tensile force in an extremely short time, the first rope body and the second rope body respectively pull the two sliding blocks to slide away from each other in the sliding openings. At this time, the elastic resetting member is stretched, thereby gradually increasing the sliding resistance of the two sliding blocks, so as to buffer the first rope body and the second rope body that generate the tensile force. The first rope body and the second rope body can have a certain deformation space after being stressed, so as to prevent the straight first rope body and the second rope body from breaking.

[0014] Further effect: When the two sliding blocks slide away from each other to a predetermined position, the sliding resistance of the sliding blocks can be gradually increased through the inclined openings, thereby gradually reducing the tensile force applied to the first line body and the second line body. After the first line body and the second line body are stretched by an external force, the first line body and the second line body can be further buffered.

[0015] Further effect: When the two sliding blocks slide away from each other, the two sliding blocks pull the elastic connecting rope to generate elastic deformation, so that the two sliding blocks can provide the effect of connecting and buffering the tensile force when sliding away from each other. Through the setting of the elastic sphere, when receiving the tensile force, elastic deformation can be generated first through the elastic sphere. When the elastic sphere is compressed and deformed, the elastic connecting rope is deformed, so as to improve the buffering effect on the tensile force.

[0016] Further effect: When the elastic connecting rope is pulled by the tensile force and the elastic sphere deforms, the polyurethane foam is compressed in the filling inner cavity. Through the soft polyurethane foam, the softness of the elastic sphere can be improved. When the elastic connecting rope loses the tensile force, through the resilience of the polyurethane foam and the rubber characteristics of the elastic sphere itself, the overall resilience effect of the elastic sphere can be improved. Compared with simply setting the elastic sphere as solid, the softness is improved and the buffering effect on the tensile force is increased.

[0017] Further effect: When the elastic connecting rope is pulled by the tensile force, the connecting rope pulls the elastic sphere in the auxiliary opening away from the sliding block, so that the elastic ball block presses against the inner wall of the auxiliary block to generate elastic deformation. Until the elastic ball block cannot deform, the tensile force is then transmitted to the elastic connecting rope for buffering.

[0018] Further effect: The setting of the guide groove and the guide block can guide the moving directions of the two sliding blocks when the two sliding blocks move away from each other in the sliding opening, and prevent the two sliding blocks from disengaging from the sliding opening.

[0019] Further effect: When it is necessary to replace the entire connecting block or the elastic connecting rope, simply use a tool to turn the abutting bolts on the two sliding blocks to make them disengage from the extrusion of the first wire body and the second wire body. Then take out the new entire connecting block, align the first wire body with the connecting wire groove of one of the sliding blocks first, and push the first wire body into the connecting wire groove. Then use a tool to screw the abutting bolt on this sliding block into the connecting wire groove until the abutting bolt completely presses the wire body tightly in the connecting wire groove. Then, connect the second wire body to the other sliding block in the same connection manner. Brief Description of the Drawings

Detailed implementation manners

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Referring to Figures 1 to 11 As shown, the technical solution adopted in this specific implementation manner is: an umbrella capable of preventing the umbrella rib stay wire from breaking, including an umbrella middle rod 1, a sliding sleeve 2 slidably disposed on the umbrella middle rod 1, and umbrella ribs respectively hinged between the umbrella middle rod 1 and the sliding sleeve 2. The umbrella ribs include a main umbrella rib 3 hinged at one end to the upper end of the umbrella middle rod 1, support umbrella ribs 4 respectively hinged between the other end of the main umbrella rib 3 and the sliding sleeve 2, a secondary umbrella rib 5 hinged at one end to the other end of the main umbrella rib 3, an outer umbrella rib 6 hinged at one end to the other end of the secondary umbrella rib 5, a connecting tie rod 7 disposed at one end on one end of the secondary umbrella rib 5, and a connecting stay wire hinged at one end to the other end of the connecting tie rod 7 and connected at the other end to the other end of the outer umbrella rib 6. The connecting stay wire includes a first wire body 8 hinged at one end to the other end of the connecting tie rod 7; A second wire body 9 disposed at one end on the other end of the outer umbrella rib 6; A connecting block 10 disposed between the other end of the first wire body 8 and the other end of the second wire body 9; A sliding opening 11 opened on the connecting block 10; Two sliding blocks 12 slidably disposed on the connecting block 10 within the sliding opening 11, and the two sliding blocks 12 are respectively connected to the other end of the first wire body 8 and the other end of the second wire body 9 Two wire threading holes 13 respectively opened at the left and right ends of the connecting block 10 and communicating with the sliding opening 11. The two wire threading holes 13 are in clearance fit with the first wire body 8 and the second wire body 9, and the first wire body 8 and the second wire body 9 respectively pass through the wire threading holes 13 and are fixedly connected to the two sliding blocks 12; An elastic reset member disposed between the two sliding blocks 12.

[0025] An umbrella surface is also provided between the upper end surface of the umbrella middle rod 1 and the umbrella ribs. The umbrella surface is installed on the umbrella middle rod 1 and the umbrella ribs by means of sewing threads, assembly blocks, etc., so as to form a complete umbrella. This structure is the structure of a conventional umbrella and will not be elaborated here. A plurality of groups of umbrella ribs are arranged between the umbrella middle rod 1 and the sliding sleeve 2. The plurality of groups of umbrella ribs are arranged annularly and equidistantly between the umbrella middle rod 1 and the sliding sleeve 2. Each group of umbrella ribs includes corresponding main umbrella ribs 3, support umbrella ribs 4, auxiliary umbrella ribs 5, outer umbrella ribs 6, connecting pull rods 7 and connecting pull ropes. The first wire body 8 and the second wire body 9 have the same length, and the connecting block 10 and the sliding block 12 are arranged to connect the first wire body 8 and the second wire body 9. When the umbrella ribs are in a contracted state (the umbrella is closed) on the umbrella middle rod 1 and the sliding sleeve 2, the first wire body 8, the second wire body 9 and the connecting block 10 are in a straight line or a slightly bent state. When opening the umbrella with great force or when the umbrella ribs are bent, the two sliding blocks 12 can be driven to move away from each other in the sliding openings 11 by the tension applied to the wire bodies, so as to reserve the stretching space of the first wire body 8 and the second wire body 9 through this setting and reduce the situation of breakage caused by excessive straightening. The hinged settings of the main umbrella ribs 3, support umbrella ribs 4, auxiliary umbrella ribs 5, outer umbrella ribs 6, connecting pull rods 7 and connecting pull ropes are as shown in the figure. The umbrella ribs are arranged as conventional umbrella ribs. The present application lies in the improvement of the connecting pull rope. The hinged structure and connection points are prior art and will not be elaborated here.

[0026] When opening the umbrella with great force or using the umbrella in strong wind weather, the umbrella ribs are instantly opened or the umbrella surface is blown by strong wind to bend the umbrella ribs. The umbrella ribs and the pull wires bear the suddenly applied tension in a very short time. At this time, the pull wires cannot buffer the generated tension, resulting in the situation that the pull wires are prone to breakage.

[0027] Two inclined openings 14 are symmetrically opened on the connecting block 10. The two inclined openings 14 are respectively communicated with the sliding opening 11 and the wire passing hole 13. On the two sliding blocks 12, chamfered surfaces 15 are arranged at the ends close to the inclined openings 14. As Figure 5 and Figure 7 and Figure 8 shown, the opening angle of the inclined opening 14 is 4° to 8°. In the present application, the opening angle of the inclined opening 14 is 6°.

[0028] The elastic resetting member includes an elastic connecting rope 16 respectively arranged between the two sliding blocks 12 and located in the sliding opening 11, and at least one elastic sphere 17 arranged on the elastic connecting rope 16. The elastic connecting rope 16 and the elastic sphere 17 are made of silicone rubber rope or cis-1,4-polybutadiene rubber material. When the elastic spheres 17 are arranged in two, the two elastic spheres 17 are symmetrically arranged on the elastic connecting rope 16.

[0029] The elastic sphere 17 is provided with a filling inner cavity 18, and a polyurethane foam layer 19 is arranged in the filling inner cavity 18 of the elastic sphere 17. Polyurethane foam has excellent resilience and cushioning properties. Polyurethane foam can quickly return to its original shape after being pressed, and can slowly recover after the pressure is released, and its resilience rate can reach more than 90%. This means that even after long-term use, the material can still maintain its original elasticity and shape, without deformation and collapse. The polyurethane foam is injected into the elastic sphere 17 through a 1mm - 3mm needle, and the injection amount is one-tenth or one-twentieth of the volume of the filling inner cavity 18, so that the injected polyurethane foam expands and fills the filling inner cavity 18.

[0030] An auxiliary block 20 is arranged on the sliding block 12. An auxiliary opening 21 is formed in the auxiliary block 20. An elastic ball block 22 is arranged in the auxiliary opening 21 of the auxiliary block 20. A connecting rope 23 is arranged between the elastic connecting rope 16 and the elastic ball block 22. An auxiliary rope hole 24 is formed in the auxiliary block 20, and the auxiliary rope hole 24 communicates with the auxiliary opening 21. The connecting rope 23 passes through the auxiliary rope hole 24 and is connected to the elastic ball block 22.

[0031] The elastic ball block 22 is a rubber block or a silica gel block. The connecting rope 23 is a nylon rope. The elastic ball block 22 is movably arranged in the auxiliary opening 21. As Figure 10 shown, auxiliary blocks 20, auxiliary openings 21, elastic ball blocks 22, connecting ropes 23, and auxiliary rope holes 24 are all arranged on the two sliding blocks 12. The diameter of the auxiliary rope hole 24 is smaller than the diameter of the elastic ball block 22.

[0032] The sliding opening 11 is penetrated and provided on the connecting block 10. The sliding opening 11 is provided along the length direction of the connecting block 10. Two guiding grooves 25 are provided on the connecting block 10. The guiding grooves 25 communicate with the sliding opening 11. The two guiding grooves 25 are respectively provided on the upper and lower sides of the sliding block 12. Guide blocks 26 are respectively arranged on the upper and lower end faces of the two sliding blocks 12. The guide blocks 26 are in clearance fit with the guiding grooves 25. The width of the guiding groove 25 is smaller than the width of the sliding opening 11. The sliding opening 11 may not be penetrated, and the sliding opening 11 is provided inside the connecting block 10, so that the guiding grooves 25 and the guide blocks 26 may not be provided. At this time, the connecting block 10 is provided in a split manner, that is, the connecting block 10 is spliced by two blocks, and a sliding opening 11, a wire passing hole 13, an inclined opening 14 and a guiding groove 25 are formed after the two blocks are spliced. During installation, the two sliding blocks 12 are respectively connected to the first rope body and the second rope body, and then the two split blocks are wrapped on the two sliding blocks 12, so that the sliding blocks 12 are located in the sliding opening 11 after splicing, and the guide blocks 26 are matched with the guiding grooves 25, and then the two blocks are fixed by means of adhesive or hot melt fixing, or by means of clamping of a plug rod and a plug slot, so as to form the connecting block 10.

[0033] Connecting wire grooves 27 are respectively provided on the two sliding blocks 12. Thread grooves 28 are provided on the side end faces of the two sliding blocks 12. The lower end of the thread groove 28 communicates with the connecting wire groove 27. The connecting wire groove 27 is in clearance fit with the first wire body 8 and the second wire body 9. A contact bolt 29 is threadedly connected between the sliding block 12 and the limiting plate. The contact bolt 29 is threadedly connected in the thread groove 28. The thread grooves 28 are respectively provided on the front side or the rear side of the two sliding blocks 12. A counterbore is provided on the corresponding setting surface for hiding the head of the contact bolt 29 when the contact bolt 29 is installed on the sliding block 12.

[0034] The working principle of the present invention: When the umbrella is opened with great force or used in strong wind weather, so that the connecting pull rope bears a suddenly applied tensile force in a very short time, the first rope body 8 and the second rope body 9 respectively pull the two sliding blocks 12 to slide away from each other in the sliding opening 11. At this time, the elastic connecting rope 16 and the elastic sphere 17 are stretched, so as to gradually increase the sliding resistance of the two sliding blocks 12, thereby buffering the first rope body 8 and the second rope body 9 generating the tensile force, and enabling the first rope body 8 and the second rope body 9 to have a certain deformation space after being stressed, so as to prevent the first rope body 8 and the second rope body 9 from being straightened and breaking. When it is necessary to replace the entire connecting block 10 or the elastic connecting rope 16, it is only necessary to use a tool to screw the abutment bolts 29 on the two sliding blocks 12 to disengage the first wire body 8 and the second wire body 9, then take out the new connecting block 10 as a whole, align the first wire body 8 with the connecting wire groove 27 of one of the sliding blocks 12, and push the first wire body 8 into the connecting wire groove 27, then use a tool to screw the abutment bolts 29 on the sliding block 12 into the connecting wire groove 27 until the abutment bolts 29 completely press the wire body into the connecting wire groove 27, and then connect the second wire body 9 to the other sliding block 12 in the same way. The guide groove 25 and the guide block 26 are provided to guide the moving directions of the two sliding blocks 12 when the two sliding blocks 12 move away from each other in the sliding opening 11, and prevent the two sliding blocks 12 from escaping from the sliding opening 11; When the elastic connecting rope 16 is pulled by tension, the connecting rope 23 pulls the elastic ball 17 in the auxiliary opening 21 away from the end of the sliding block 12, so that the elastic ball block 22 is pressed against the inner wall of the auxiliary block 20 to produce elastic deformation, until the elastic ball block 22 can no longer be deformed, and then the tension is transmitted to the elastic connecting rope 16 for buffering; When the elastic connecting rope 16 is pulled by tension and the elastic sphere 17 is deformed, the polyurethane foam is compressed in the filling inner cavity 18. The softness of the elastic sphere 17 can be improved by the soft polyurethane foam. When the elastic connecting rope 16 loses the tension, the overall rebound effect of the elastic sphere 17 can be improved by the resilience of the polyurethane foam and the rubber properties of the elastic sphere 17. Compared with simply directly setting the elastic sphere 17 to be solid, the softness is improved and the buffering effect of the tension is increased. When the two sliding blocks 12 move away from each other, the two sliding blocks 12 pull the elastic connecting rope 16 to generate elastic deformation, so that the two sliding blocks 12 can provide connection and buffering effect of tension when sliding away from each other, and through the setting of the elastic sphere 17, when subjected to tension, the elastic sphere 17 can first generate elastic deformation, and when the elastic sphere 17 is compressed and deformed, it is deformed through the elastic connecting rope 16, thereby improving the buffering effect of tension; When the two sliding blocks 12 move away from each other to a predetermined position, the inclined opening 14 can gradually increase the resistance to the sliding of the sliding block 12, thereby gradually reducing the tension applied to the first wire body 8 and the second wire body 9, and further buffering the first wire body 8 and the second wire body 9 after the first wire body 8 and the second wire body 9 are stretched by external force.
