Description

Technical Field

[0001] The utility model relates to a pergola. Background Art

[0002] As a tool for sunshade and rain shelter, outdoor pergolas are widely used in family travel, business promotion and disaster relief. Generally, pergolas are supported by multiple groups of rods to hold up the tarpaulin. The main disadvantage is that the pergola bracket is large in size, takes up space, and is inconvenient to carry. Although foldable and assembled pergola structures have appeared in recent years, there are still certain disadvantages. The current pergolas mainly include roof brackets, folding brackets and columns. The columns are relatively retractable, but the current retraction uses a button buckle (spring clip) structure. In this way, when the column is extended, each gear must be pressed once to extend the column to the maximum state. This operation is time-consuming and labor-intensive, and the limiting holes are now on the end face. Such a structure is not stable enough. Long-term use can easily cause distortion of the end face, affecting the service life of the pergola. Summary of the Invention

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] With reference to the drawings in the specification, a pergola comprises a supporting column A, wherein the column comprises a first connecting rod 10 and a second connecting rod 20, the first connecting rod is sleeved on the outer periphery of the second connecting rod, and the second connecting rod can move axially relative to the first connecting rod. When the pergola is in operation, the axial direction is the up and down direction, that is, the second connecting rod can be pulled out or retracted from the first connecting rod, thereby realizing the folding or length adjustment of the pergola, and the outer periphery of the second connecting rod is provided with at least two axially distributed second clamping grooves 21, including two or more, each second clamping groove can form a gear position of the column, and each second clamping groove is a gear position, and the second clamping groove includes a second inclined surface 22 inclined upward from the inside to the outside, when the second connecting rod is pulled out from the first connecting rod, the clamping piece can cooperate with the second inclined surface so that the clamping piece can be continuously ejected from the second clamping groove, so that the column can be pulled to the maximum size at one time, and the outer periphery of the first connecting rod is provided with a first clamping groove that can be adapted to the second clamping groove 11; A fixing sleeve 30 is sleeved on the outer periphery of the lower end of the first connecting rod, and a button 40 is provided at the fixing sleeve. The middle part of the button is hinged to the fixing sleeve through an axis pin 31. One end of the button is provided with a clamping piece that can pass through the first clamping groove and engage with the second clamping groove. An elastic piece is provided between the other end of the button and the fixing sleeve. The elastic piece can make the clamping piece move toward the second clamping groove so that the clamping piece is engaged with the second clamping groove. When the second connecting rod is pulled out from the first connecting rod, the second inclined surface can push the clamping piece out of the first clamping groove. In use of the utility model, the upper part of the button is a pressing surface 42, which has a large contact area and can reduce the pain of the finger when pressing. The clamping piece is located below the button. When the clamping piece cooperates with the second inclined surface, the clamping piece is pushed outward and the elastic piece is compressed until the clamping piece reaches the next second clamping groove, and then through the cooperation of the second inclined surface, the column can be stretched at one time. At this time, the elastic piece is passively compressed. When it is necessary to shorten the column, that is, retract the second connecting rod to the first connecting rod, press the pressing surface, mainly compress the elastic member, so that the clamping member disengages from the second clamping groove, and then retract the second connecting rod to the first connecting rod. After releasing the pressing surface, when reaching the next second clamping groove, the elastic member rebounds and clamps the clamping member into the second clamping groove, thereby shortening the distance of one gear.

[0031] Preferably, the elastic member is a torsion spring 32, which is sleeved around the outer periphery of the pin shaft, with one end of the torsion spring matingly connected to the fixing sleeve, and the other end of the torsion spring matingly connected to the other end of the button. The engaging member is a bayonet 41, which is provided with one end of the button and can be engaged in the second bayonet slot via the first bayonet slot.

[0032] Furthermore, the second coupling groove also includes a receiving surface 23, and the connection between the inner side of the receiving surface and the lower side of the second inclined surface forms a coupling point 24. The latch can be placed at the coupling point, which is a gear position, and the receiving surface can be flush with the horizontal plane, or the receiving surface can be tilted outward from the coupling point to ensure that the height of the column will not be shortened when the pergola is in use.

[0033] Furthermore, the first engaging groove includes a first inclined surface 12 and a plane 13. The first inclined surface is arranged on the outer periphery of the first connecting rod and is inclined downward from the inside to the outside. The plane can be flush with the horizontal plane. The inclination directions of the first inclined surface and the second inclined surface are opposite.

[0034] Preferably, the system further includes a ceiling bracket 50 and a folding bracket 60. The ceiling bracket is located above the column. The upper end of the first connecting rod is provided with a fixed seat 70, and the lower end of the ceiling bracket can be hinged to the fixed seat. A folding bracket is provided between two adjacent columns, preferably with four columns and four folding brackets. The folding bracket includes a cross rod 61, the upper end of which can be hinged to the fixed seat. The outer periphery of the first connecting rod located below the fixed seat is provided with a sliding sleeve 71, and the lower end of the cross rod can be hinged to the sliding sleeve. The ceiling bracket and folding bracket are similar to those in the prior art and will not be elaborated on here.

[0035] Preferably, a support piece 80 is provided at the lower end of the second connecting rod, and the cross-sectional area of the support piece is larger than the cross-sectional area of the second connecting rod, thereby improving the stability of the column when it is erected.

[0036] In one embodiment of the present invention, the first connecting rod and the second connecting rod are square tubes, and the first clamping groove and the second clamping groove are provided on the edge 91 of the square tube.

[0037] In another embodiment of the present invention, the first connecting rod and the second connecting rod are square tubes, one edge of the square tube is retracted inward to form a narrow surface 92, the width of the narrow surface is smaller than the width of other surfaces of the square tube, and the first clamping groove and the second clamping groove are provided on the narrow surface.

[0038] Specifically, the two connecting rods are both square tubes, and the two snap-in grooves are arranged at the corners, or on the narrow surface of the original corners, to increase the strength used to support the bayonet. If they are on the wide surface, the force on the surface is unstable, and the surface is prone to distortion, so that the pergola is easy to bend and tilt, posing a safety hazard; the first snap-in groove and the second snap-in groove can have a triangular cross-section on the vertical surface, preferably a right-angled triangle.

[0039] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
