Therefore, the force needed for fixing the umbrella on the lamp is very small, and the umbrella can be conveniently and quickly operated by one hand of a user.

At the initial stage of the umbrella pole entering the locking channel, a portion of the weight of the housing is already shared by the umbrella pole. Moreover, the narrow end opening of the locking channel and the umbrella rod enable the locking channel to be in close contact with and extruded with the umbrella rod due to acting force between the narrow end opening of the locking channel and the umbrella rod, and rainwater cannot be allowed to enter the damping belt under the condition that the umbrella leaks rain.

Detailed Description

The following detailed description is made with reference to the accompanying drawings.

Damping refers to the characteristic that the amplitude of vibration of any vibration system is gradually reduced in vibration due to external action or the inherent reason of the system, and the quantitative representation of the characteristic. The physical meaning of damping is the attenuation of force, or the dissipation of energy by an object in motion. In general terms, the object is prevented from continuing to move. When an object vibrates by an external force, a reaction force, called a damping force (or shock absorbing force), is generated to attenuate the external force. The direction of the damping force is usually always opposite to the direction of the speed of the movement.

The damping band of the invention belongs to a damping mechanism and comprises an elastic band with elasticity, a spring band, a metal sheet and a mechanical mechanism with an elastic function. The mechanical mechanism with elastic function can be a bending elastic sheet with elasticity, a spring component, an elastic component formed by elastic materials and components without elastic materials.

The elastic band comprises an elastic band and a soft rubber strip with a larger friction coefficient. The larger the friction coefficient of the elastic band is, the better the elasticity is, the larger the acting force between the damping band and the umbrella rod is, and the better the effect is.

Generally, the umbrella rod of a common umbrella is a hollow umbrella rod. The axial strength of the common umbrella rod is large, and the radial strength is limited due to the hollow structure, so that the common umbrella rod needs to be fixed in a surface contact mode in the axial direction. Particularly, for the umbrella rods of the folding umbrella, the thickness of each umbrella rod is different due to the need of extension and contraction, and the fixing part of the fixing device needs to be conveniently adjusted.

In addition, such an axial fixing structure is not suitable for fastening at the lower end of the shaft in view of the lever effect. The upper end of the umbrella rod is loose, the umbrella rod is deformed due to the weight of the lamp held by the shell of the fixing device, and the long-term stability of the umbrella is not facilitated. Thus, the fixture should be removable and easy to install and remove with one-handed operation.

Based on the structural characteristics of the invention, the invention can apply various names such as lighting mechanism, lamp, fixing mechanism, solar lighting mechanism, solar lamp and the like.

Example 1

The present invention provides a lighting mechanism for securing to a shaft, and a securing device 100 is detachably secured to an umbrella shaft 50. The fixing means 100 wraps around a portion of the umbrella shaft 50 so that the fixing means 100 and the umbrella shaft 50 increase a contact area, increase friction force and are fixed relative to each other. The umbrella rod of the invention can be a solid umbrella rod. The umbrella rod comprises a cylindrical umbrella rod and a polygonal cylindrical umbrella rod. As shown in FIG. 1, the light of the present invention, which includes a fixture 100, is mounted on the shaft below the canopy 200. When light is required, the user turns on the switch on the housing 10 of the fixing device 100 to turn on the illumination device 107 for illumination.

The invention provides a lamp for fixing to a rod, in particular to an umbrella rod. The fixing device comprises a housing provided with a locking channel and at least two parallel damping strips. At least one lighting device is disposed on the housing. The damping strips are arranged substantially parallel to one another in the locking channel of the housing, so that, without the fixing device being installed, the locking channel is divided into at least three regions in a radial plane perpendicular to the umbrella pole by at least two damping strips, wherein the fixing device is detachably fixed to the umbrella pole in such a way that the axially upper surface engages the pole wall at least by virtue of the intermediate regions between which the at least two damping strips are formed.

Referring to fig. 2, a fastening device 100 of the present invention is shown. The fixture 100 includes at least a housing 10, a damping band 20, a one-handed locking mechanism 30 and a pitch mechanism 40. The housing 10 includes a first housing 101 and a second housing 102. The first housing 101 is an arc-shaped housing, and a first concave cavity is formed on a straight line-shaped edge connected with the arc-shaped housing. The second housing 102 is an arc-shaped housing, and the straight edge of the second housing connected with the arc-shaped housing is provided with a concave second cavity. The first housing 101 and the second housing 102 are combined into a complete circular housing. The first and second cavities combine to form a locking channel 108 that receives the column therethrough. The distance adjustment mechanism 40 mechanically connects the first ends of the first and

second housings

101 and 102 and can adjust the distance between the first and second housing first ends. The one-hand operated locking mechanism 30 connects and fixes the second ends of the first and

second housings

101 and 102 in a mechanically locked manner. The one-hand operated latch mechanism 30 includes a catch 103 provided at the second end of the first housing 101 and a catch 104 provided at the second end of the second housing 102. The catch 103 and the catch 104 are mutually mating locking parts.

At least one damping strip 20 is disposed within the locking channel 108. The damping band 20 is disposed in a radial direction of the cavity and both ends are fixed to the case 10. Preferably, both ends of the damping band 20 are fixed to the first case 101 and/or the second case 102. The first and

second housings

101 and 102 are gathered and combined in a corresponding manner into the housing 10 accommodating the umbrella pole 50 based on one-handed force. The damping band 20 resiliently secures the umbrella pole located in the locking channel 108 relative to the housing 10 based on the force 60 between the umbrella pole 50 and the damping band 20. The distance adjustment mechanism 40 fixes the distance between the first end of the first housing 101 and the first end of the second housing 102 so that the first housing 101 and the second housing 102 are not separated by the reaction of the force when the second end of the first housing 101 and the second end of the second housing 102 are close to each other, but the distance surrounds the umbrella pole 50 less and less.

Preferably, the locking channel 108 includes a damping band 20. Both ends of the damping band 20 are fixed to the first casing 101 and/or the second casing 102. Preferably, the distance of the middle area of the damping band is smaller than the diameter of the umbrella rod, so that the umbrella rod can extrude the damping band to generate deformation. For example, both ends of the damping band 20 are fixed to the first housing 101, and a rubber inner wall is provided in the second cavity of the second housing 102. When the first housing 101 and the second housing 102 are moved together and combined by the one-hand force, the damping band 20 is deformed and elastically moved by the force of the second housing 102 pressing the umbrella pole 50, so that the damping band 20 fixes the umbrella pole in the locking passage 108 and the housing 10 by the elastic force.

Preferably, at least two parallel damping strips 20 are arranged in the locking channel. At least two damping belts are arranged in the locking channel in a parallel mode along the radial direction of the locking channel, and the at least two damping belts are positioned on two sides of the umbrella pole. Both ends of at least one first damping band 101 are disposed on the first cavity of the first housing 101, and both ends of at least one second damping band 102 are disposed on the second cavity of the second housing 102. After the umbrella pole enters the locking channel, the first damping band 101 and the second damping band 102 respectively press the umbrella pole 50 between the first damping band 101 and the second damping band 102 based on the pressing force generated when the one-hand operated latch 30 fastens the first housing 101 and the second housing 102 to increase the friction force between the umbrella pole 50 and the first cavity and the second cavity and fix the umbrella pole 50. The deformation of the damping band generates an elastic force and a frictional force between the umbrella pole and the damping band. The elastic force and the friction force jointly exert the force on the umbrella rod. Meanwhile, the umbrella rod also provides acting force with the same magnitude and opposite direction to the damping belts. The acting force, the elastic force and the friction force jointly maintain the balance of the force between the fixing device and the umbrella rod.

Preferably, the surface of the damping band 20 is provided with at least one recess and/or protrusion. The recesses and/or protrusions can increase the friction between the damping band and the umbrella shaft, and between the damping band and the cavity wall of the locking channel 108. Preferably, the wall of the locking channel 108 is provided with at least one recess and/or protrusion. Preferably, the shape and depth of the concave and/or convex portions on the cavity wall of the locking channel 108 are matched to the shape and depth of the concave and/or convex portions on the surface of the damping strip, so that the damping strip contacts the cavity wall of the locking channel 108 under the pressing of the umbrella rod and increases the friction force. It is noted that the depth of the recesses and/or protrusions of the surface of the damping strip and the recesses and/or protrusions on the chamber wall is preferably such that they are able to separate quickly upon contact. This has the advantage of avoiding the damping strip from contacting the cavity wall and then becoming entangled, stuck, or stuck together, thereby losing or weakening the elastic force applied to the shaft.

Preferably, the surface of the damping belt is provided with concave parts and/or convex parts which are distributed in point symmetry and are staggered in adjacent rows and columns. The concave parts and/or the convex parts are in irregular point-shaped structures, block-shaped structures and/or strip-shaped structures. The concave part and/or the convex part on the surface of the damping band are/is frictionally fixed with the cavity walls of the umbrella rod and the locking channel respectively based on the pressing force of the shell.

Preferably, the cavity wall of the locking channel is provided with cavity wall concave parts and/or cavity wall convex parts which are distributed in point symmetry and staggered up and down. The concave and/or convex portions of the surface of the damping band interfere with the cavity wall concave and/or convex portions based on the pressing force of the housing to increase the elastic force between the damping band and the umbrella pole.

As shown in fig. 6, the concave and/or convex portions of the surface of the damping band 20 of the present invention include the central ridge 13, the side ridges 9, and the edge ridges 4, which are arranged in the radial direction of the locking channel. The central ridge 13, the lateral ridges 9 and the edge ridges 4 are spaced from one another by the lateral radial recesses 2. First axial recesses 10 are arranged between the central convex ridges 13 adjacent in the radial direction, second axial recesses 8 are arranged between the lateral convex ridges 9 adjacent in the radial direction, third axial recesses 7 are arranged between the edge convex ridges 4 adjacent in the radial direction, two sides of the central radial recess 1 are respectively communicated with the first axial recesses 10, the second axial recesses 8 and the third axial recesses 7 are respectively communicated with the adjacent lateral radial recesses 2, and the central convex ridges 13, the lateral convex ridges 9 and the edge convex ridges 4 on two sides of the central radial recess 1 are concave parts and/or convex parts which are distributed in a point symmetry manner and are staggered in adjacent rows.

Preferably, the damping band is a wide damping band, and the width of the damping band is no less than one third of the axial length of the locking channel 108. The wide surface of the damping band is parallel to the axial tangent plane of the locking channel, i.e. the damping band is directed axially towards the umbrella stem. The damping belt is arranged in such a way, so that the contact area between the damping belt and the umbrella rod and between the damping belt and the cavity wall is increased, the friction force between the damping belt and the umbrella rod and between the damping belt and the cavity wall is increased, and particularly the elastic acting force of the damping belt on the umbrella rod is increased. Preferably, one wide damping band may be formed by arranging a plurality of thin small damping bands in parallel, and both ends of the small damping bands are fixed on the housing, and there may be a gap or no gap between the small damping bands. I.e. a plurality of damping strips arranged axially or radially in parallel in the locking channel 108.

Preferably, the distance adjustment mechanism 40 between the first end of the first housing 101 and the first end of the second housing 102 is also used to adjust the distance between the first damping band 105 and the second damping band 106. Because the specifications of the umbrella rods are different and the diameters of the umbrella rods are not uniform, the distance between the damping belts cannot adapt to the umbrella rods with all specifications. In addition, the damping belt has aging phenomenon, and the elastic force changes due to long-term use and needs to be adjusted. In order to allow the damping strips to exert a resilient force on all the rods and thus to be fixed, the intermediate area between the damping strips is adjustable. Preferably, the distance adjustment mechanism 40 is mechanically coupled to one of the first end of the first housing 101 and the first end of the second housing 102 in a rotatable manner. The distance adjustment mechanism 40 is provided with a through hole for accommodating at least one damping strip 20. The damping band passes out through the through-hole of the distance adjusting mechanism 40 based on the corresponding first housing and/or second housing. Preferably, the adjustment mechanism 40 includes a locking feature to lock the at least one damping band.

Preferably, the distance adjusting mechanism 40 is a locking mechanism including a spring component, and the first damping strip 105 at the first end of the first casing 101 and the second damping strip 106 at the first end of the second casing 102 are simultaneously locked, so that the first casing and the second casing can be connected to prevent one of them from being lost, the first end of the first casing 101 and the first end of the second casing 102 can be relatively fixed, and the width of the middle area between at least two damping strips can be adjusted.

Preferably, the position of the two ends of the damping strip on the housing 10 is adjustable. After the umbrella pole enters the locking channel 108, the user tightens or loosens the length of the damping strips through the distance adjusting mechanism 40, and adjusts the width of the middle area between the damping strips.

Preferably, the distance adjustment mechanism 40 is connected to at least one end fixing member of the first damping band 105 and at least one end fixing member of the second damping band 106. The user adjusts the position of at least one end fixing component of the first damping band 105 and at least one end fixing component of the second damping band 106 on the first casing or the second casing by the distance adjusting mechanism 40, thereby adjusting the width of the middle area between the first damping band and the second damping band

Preferably, the damping strip of the present invention is replaceable, i.e., the fixing components at both ends of the damping strip are detachably fixed to the housing 10. The damping band is replaced when losing its fixing ability after ageing.

Preferably, the fixing device 100 is connected with the solar panel of the umbrella cover through a safety mechanism with electric conduction capability. The safety mechanism can undertake a temporary fixing task when the damping band accidentally falls off and loses a fixing function, undertakes a conductive task, and achieves double functions of a safety function and a power supply function. For example, the safety mechanism may be a wire having elasticity, and may be a safety mechanism including a wire.

Preferably, when the wire of the solar cell panel is located in the hollow umbrella pole, one end of the safety mechanism is fixed and locked with the wire of the solar cell panel through the through hole on the umbrella pole, and the other end of the safety mechanism is connected and fixed with the charging jack 109 on the fixing device 100, so that the safety mechanism connects and fixes the fixing device and the umbrella pole and carries out the conductive function.

Preferably, the locking mechanism 104 of the one-hand operation type in the present invention includes a buckle 103 disposed at one end of the first housing 101 and a lock catch 104 disposed at the corresponding end of the second housing 102, and the lock catch 104 includes a lock cavity 112 provided with an elastic member. The lock catch 104 is moved toward the catch 103 by a one-handed force that gathers the first housing 101 and the second housing 102, and the lock chamber 112 is driven by the one-handed force to lock the catch 103 that has entered the lock chamber 112 by the elastic member. The lock 104 includes a lock shaft 110, a base 111, a lock cavity 112 provided with a lock hole, and a handle 113. One end of the base 111 is rotatably connected to the second housing 102 by a lock shaft 110, the base 111 includes a lock chamber 112 provided with an elastic member, and a handle 113 has a smooth spherical shape and is provided at the other end of the base 111. The catch 104 locks with the catch 103 based on rotation of the handle 113 with a single hand force.

Preferably, the housing 10 of the fixing device 100 includes one or more of a lighting device, a battery, a charging socket, a USB socket, an audio playing module, a video playing module and a recording module. The inside of the casing 10 is provided with a cavity for accommodating a circuit and a battery, and the circuit and the battery are arranged inside the casing, so that the battery is prevented from being damaged by moisture, and the appearance and the safety are facilitated.

Preferably, the fixing device 100 may further include a plurality of functional modules, such as a communication signal module, a signal amplification module, an audio/video playing module, a broadcasting module, and the like. The present invention can provide and modify the functional modules in the housing 10 of the fixing device 100 according to the desired functions.

Example 2

The present invention is a further improvement of embodiment 1, and repeated contents are not described again.

The present embodiment provides a luminaire for fixing to a shaft, in particular an umbrella shaft, comprising a lighting device 107, a fixing device 100 and an umbrella. The fixing device 100 comprises a housing 10 provided with a locking channel and at least two parallel damping strips 20. The damping strips 20 are arranged substantially parallel to one another in the locking channel of the housing 10, so that, in the absence of the fixing device 100 being mounted, the locking channel is divided into at least three regions in a radial plane perpendicular to the shaft by at least two damping strips, wherein the fixing device 100 is detachably fixed to the shaft in such a way that the axially upper surface engages the shaft wall at least by virtue of the intermediate region between which the at least two damping strips 20 are formed.

The housing 10 is provided therein with a battery module for storing electric energy converted by the solar cell panel and supplying power to other functional modules on the housing.

As shown in fig. 3, the first housing 101 and the second housing 102 are semicircular. The first housing and the second housing combine to form a housing having a locking channel. The casing is divided into two parts, so that the fixing device can be conveniently installed at any position of the umbrella rod, the shapes of the devices at two ends of the umbrella rod do not need to be matched, and the umbrella is suitable for umbrellas of more styles. The umbrella pole is moved in from the open end between the first shell and the second shell. The first and second housings are locked and fixed by the one-hand operation type locking mechanism 30 based on one-hand acting force, so that the fixing device 100 is prevented from falling off and losing from the umbrella pole.

As shown in fig. 4, at least two damping strips are respectively provided in the half-latching passages of the first and second housings 11 and 12 in parallel with the merged line of the latching passages. At least one lighting device 107 is arranged at a horizontal side of the housing 10. The number of lighting devices may be greater. The elastic damping band is utilized to generate larger friction force with the umbrella rod, so that the fixing device is fixed on the umbrella rod through the reaction force of the umbrella rod. Preferably, the lighting device of the present invention includes various lamps such as incandescent lamps, LED lamps, colored lamps, lamp strips, and lamp strings. Preferably, the lighting device 107 is not limited to a single light bead. Preferably, the lighting device 107 further includes an infrared lamp, an ultraviolet lamp, or the like which is not used for illumination.

Preferably, the lighting device 107 is an LED lamp, and the light emitting surface of the LED lamp is in a convex shape with a radian, and the light emitting angle of the LED lamp is larger than 90 degrees. The wider light-emitting angle of the lighting device 107 can illuminate the area under the umbrella cover in a wider range, thereby reducing the shadow.

Preferably, the first end of the first housing 101 and the first end of the second housing 102 are connected by the distance adjusting mechanism 40. As shown in fig. 2, the distance adjustment mechanism 40 is disposed diametrically opposite the one-hand operated locking mechanism 30. The pitch mechanism 40 is a curved deformable member. The distance adjustment mechanism 40 is connected to one end of the first damping band 105 and one end of the second damping band 106, respectively, and adjusts the position of one end of the first damping band 105 or the second damping band 106 on the housing, respectively, thereby adjusting the intermediate region width between the first damping band 105 and the second damping band 106. Preferably, the distance adjusting mechanism 40 is provided with a through hole for adjusting the length and tightness of the damping band and allowing the damping band to pass through. The user adjusts the length and tightness of the damping band in the locking channel by adjusting the damping band extending through the through hole of the distance adjustment mechanism 40. Preferably, the distance adjusting mechanism 40 also allows the wire and the data line between the first housing and the second housing to communicate, so as to facilitate the circuit between the first housing and the second housing to share the power supply and transmit data information. For example, the wire may be a relatively flexible electrical wire.

The first housing 101 and/or the second housing 102 are provided with switches connected to the battery. At least one cavity is provided in the first housing 101 and/or the second housing 102. The battery is disposed within the cavity and is connected to at least one lighting device 107 by a wire. The lighting device 107 is fixed to the first housing 101 and/or the second housing 102 by mechanical and/or adhesive means. The battery is arranged in the cavity, so that the interference of moist air can be reduced, a power supply and a circuit are protected, and the service life of the fixing device is prolonged.

Fig. 5 shows an embodiment of a luminaire for fastening to a shaft, in particular an umbrella shaft. The umbrella cover 200 is provided with at least one solar cell panel 220. At least one solar cell panel 220 is symmetrically disposed around the central hole 210 of the umbrella cover 200. The surface of the solar cell panel 220 is provided with a first adhesive layer, and the surface of the umbrella cover 200 is provided with a second adhesive layer. The solar cell panel 220 is fixed to the umbrella cover 200 by attaching the first adhesive layer or the second adhesive layer to each other. Preferably, the solar cell panel 200 is a flexible solar cell panel. Preferably, the shape of the solar cell panel is not limited, and may be rectangular, fan-shaped, circular, and irregular. The invention uses flexible material to fix the solar cell panel. The periphery of at least one solar cell panel is coated with flexible materials and is connected through the flexible materials to form a solar cell group similar to an umbrella surface shape, and the solar cell group is fixed on the rod-shaped object in a detachable sticking, mechanical fixing or support supporting mode. Or, the center of the solar battery pack is provided with a through hole allowing the umbrella rod to pass through, and under the condition that the detachable end is fixedly connected with the umbrella rod, the solar battery pack is fixed between the end and the umbrella cover of the umbrella in a bolt fixing mode by the end. The solar cell panel is fixed at the umbrella top by the plastic fixing bolt of original umbrella top, under the condition of not destroying original umbrella face, easily realizes the technical effect that the solar cell panel of umbrella top charges for the lamps and lanterns in the umbrella through the lead wire, and is simple easily operation.

Preferably, at least one fan-shaped solar cell panel 220 is symmetrically distributed around the central hole 210 and forms an umbrella-shaped solar cell panel. Preferably, the umbrella-shaped solar cell panel passes through the hollow umbrella rod 50 through the central hole 210 and is provided with a knob attached to the top end of the umbrella rod of the umbrella cover 200. After the umbrella-shaped solar cell panel 220 passes through the umbrella pole, the knob is mechanically fixed to the top end of the umbrella pole so as to further fix the umbrella-shaped solar cell panel 220 on the umbrella face 220. Preferably, when the umbrella-shaped solar panel is fixed by the knob, the umbrella-shaped solar panel and the umbrella cover are adhered by the adhesive tape or fixed by the rivet. Thus, the solar cell panel can be firmly attached to the surface of the umbrella under the action of outdoor wind power.

Preferably, the outer surface and/or the inner surface of the umbrella cover are/is provided with magic tapes. When the sun exists, the solar panel is fixed on the outer surface of the umbrella cover 200, and the solar energy is converted into electric energy. Or when the umbrella cover is a transparent umbrella cover, the solar cell panel 220 penetrates through the umbrella rod and is fixed on the inner surface of the umbrella cover based on the thread gluing tape, so that the solar cell panel is prevented from being damaged, and the absorption of the solar cell panel on solar energy is not influenced. Alternatively, when the solar cell panel 220 is not needed for use, the user sticks the solar cell panel 220 to the inner surface of the umbrella cover 200, i.e., the surface facing the umbrella shaft. Thus, the solar panel 220 does not occupy other space for storage, and is protected from wind and rain by the umbrella cover.

Preferably, rivets are used to join the flexible solar panel 220 to the canopy 200. Preferably, the solar cell panel of the present invention is a flexible and portable solar cell panel laminated with PET. The soft portable solar cell panel reduces the weight of the umbrella and is convenient for folding and unfolding the umbrella.

Preferably, the edge of the flexible solar cell panel is provided with a hem 230. Preferably, canvas is used as the covering edge 230 to be sewn with the solar cell panel, so that the solar cell panels can be spliced together. The hem 230 protects the solar panels from rubbing against each other and from edge loss.

Preferably, the umbrella comprises ribs 300. The solar cell panels 220 are distributed in regions divided by the ribs 300. This is advantageous in that the solar cell panel 220 is folded and bent along the umbrella rib 300, so that the folding line where the solar cell panel and the umbrella cover are gathered does not collide with each other, thereby protecting the solar cell panel.

Example 3

This embodiment is an improvement on embodiment 1 or embodiment 2 and a combination thereof, and repeated details are not described again.

The lock passage 108 in the housing 10 has a constricted portion in the axial direction. The constricted portion is preferably formed so as to become larger from the canopy toward the shaft in the axial direction. Preferably, the necking part is in a shape of gradually increasing or gradually increasing from the umbrella cover to the umbrella rod along the axial direction. For example, the axial direction in which the fixing device 108 is fixed to the umbrella shaft will be described. As shown in fig. 7, the upper portion of the lock passage 108 has a smaller diameter than the lower portion in the axial direction. The locking channel 108 is narrow at the top and wide at the bottom, and is loose at the top. Preferably, the transverse shape of the locking channel 108 includes a circular shape, a polygonal shape, a rectangular shape, and the like.

The form of the locking channel with narrow top and wide bottom is beneficial to matching with the form change of the damping band, reducing the deformation degree of the damping band, delaying the aging speed of the damping band and prolonging the service life of the damping band. Since the force of the user's hand acts on the housing 10 of the fixing device 100 when putting the umbrella pole into the locking channel. At the moment, the gravity center of the umbrella enables the umbrella rod to be in a falling trend in the locking channel. The axial side surface of the damping belt is jointed with the umbrella rod and is in a falling trend together with the umbrella rod, so that the damping belt deforms and slides downwards in the axial direction, but wrinkles and folds are generated due to insufficient loose space. This clearly increases the probability of damage and ageing of the damping strip. After the fixing device is fixed by a user, acting force of the hand acts on the umbrella rod, and the fixing device falls down due to self gravity acting force. Long term use can cause the damping band to deform significantly by bearing the weight of the umbrella. Therefore, a form improvement of the locking channel is necessary. After the locking channel is modified to have a narrow top and a wide bottom, the narrow port of the fixing device 100 on the shaft is positioned above the wide port in the umbrella use configuration. The narrow port of the locking channel enables the damping belt to be tighter to the umbrella rod, and the inclined locking channel cavity wall receives the upward inclined force directly applied by the umbrella rod or indirectly applied by the damping belt due to the inclined angle, so that the gravity of the shell body is supported by the umbrella rod instead of being supported by the friction force of the damping belt. The channel form that the locking channel is narrow from top to bottom loose has reduced the gravity that the damping area received, and then has reduced the elasticity and the deformation degree of damping area, has delayed the deformation and ageing of damping area, has reduced the change frequency of damping area.

Preferably, the damping band 20 has at least two elastic forces in the axial direction. The elastic force of the damping belt is further improved in different areas, so that the elastic force of the damping belt is larger, the fixing effect is more obvious, and the damping belt is wear-resistant and durable.

As shown in fig. 7, the damping band 20 includes a first width section 21 and a second width section 22 in the axial direction. The elastic force of the first width section 21 is not greater than the elastic force of the second width section 22 having a lower axial height than the first width section. The first width section 21 has a weak elasticity and a high hardness, and is not easily wrinkled. I.e. the first width interval 21 is deformed to a lesser extent in the axial direction. The first width section 21 of the damping band 20 cooperates with the narrow end of the locking channel 108 to apply force to the umbrella pole, and if the damping band is folded, the damping band is more easily damaged due to long-term extrusion, so that a large elastic force is not needed. In addition, the first width section 21 having high hardness is resistant to wear, and the edges of the damping belt can be prevented from being damaged by deformation.

The second width section 22 is located axially below the first width section 21. The second width section 22 has a large elastic force, and can apply a large elastic force to the umbrella shaft and generate a large deformation. The part of the locking channel corresponding to the second width zone 22 is already widened and is not mechanically pressed by the locking channel for a long time, which leads to hardening, so that the second width zone 22 is less stiff, but not without stiffness. The elastic force setting and hardness setting of the second width section 22 not only meet the magnitude of acting force required by installing the fixing device 100, but also adaptively reduce the wrinkles of the second width section of the damping band. In addition, the outer surface material of the second breadth section 22 is additionally provided with fibers to enhance the surface hardness, so that the wear resistance is ensured, and the long-term extrusion cannot fail.

As shown in fig. 8, the elastic force of the third width section 23 located between the first width section and the second width section is not less than the elastic force of the dead width section. I.e. the third width interval 23 is the most resilient. The third width section 23 of the damping band has the greatest spring force and the least stiffness, and the corresponding locking channel portion has been widened. The third width zone 23 is located in the middle and does not need to consider the problem of wear per se but only the problem of elasticity. Therefore, the third width section 23 is suitably arranged to have the greatest spring force and the weakest spring force, and is not mechanically pressed by the lock channel for a long time, which may cause hardening and thus failure.

In the state that the umbrella rod 50 and the locking channel 108 are relatively fixed, the damping band 20 forms a stable fit structure with the locking channel 108 in the axial direction based on the damping band form formed by at least two different elastic forces. Namely, after the fixing device is installed on the umbrella pole, the hardness of the first width area 21 of the damping band resists the extrusion of the narrow port of the fixing device and does not generate wrinkles, the friction acting force generated by the smaller elastic force fixes the umbrella pole, and the first edge of the damping band is protected from abrasion while the umbrella pole supports the gravity of the shell due to the angle force application. The third width zone 23 of the damping band is deformed considerably and fixes the umbrella pole with a strong elastic force. At this time, although the third width section 23 is largely deformed and has many wrinkles, the corresponding lock passage portion is already widened, and thus the deformed portion of the damping band is appropriately received. The second breadth interval 22 of the damping band then secures the umbrella pole with moderate elastic strength and stiffness, while reducing the wrinkling of the damping band. The lower edge of the damping belt bears long-term extrusion due to medium hardness to resist abrasion, and damage to the damping belt is reduced. Namely, the form trend of the deformed damping band is matched and matched with the form of the locking channel, and the fixing effect is obvious. By combining the difference setting of the elasticity and hardness of the first width section 21, the second width section 22 and the third width section 23 of the damping belt, the abrasion of the damping belt is reduced and the service life of the damping belt is prolonged under the condition of enhancing the elasticity effect of the damping belt.

After the parallel first damping band 105 and second damping band 106 are arranged in the locking channel with the constricted portion. The parallel first 105 and second 106 damping bands divide the locking channel radially into three zones: a first region between the first damping band 105 and the first casing, an intermediate region (third region) between the first damping band 105 and the second damping band 106, and a second region between the second damping band 106 and the second casing.

During the process that the umbrella pole enters the locking channel and the first housing 101 and the second housing 102 are combined, the umbrella pole is attached and deformed based on the first damping band 105 and the second damping band 106 to press the space of the first region and the second region. At this time, since the narrow port of the locking channel is narrow, the umbrella pole firstly contacts the shells of the first area and the second area through the first width sections 21 of the two damping belts, and directly contacts and generates acting force with the shell of the middle area, and generates force action between each other. That is, at the initial stage of the umbrella pole entering the locking channel, a portion of the weight of the housing is already shared by the umbrella pole. Moreover, the narrow end opening of the locking channel and the umbrella rod enable the locking channel to be in close contact with and extruded with the umbrella rod due to acting force between the narrow end opening of the locking channel and the umbrella rod, and rainwater cannot be allowed to enter the damping belt under the condition that the umbrella leaks rain.

The remaining weight of the housing is balanced by the maximum spring force generating friction force of the third width section 23 of the damping strip. At this time, the first region, the middle region and the second region are further widened, the third width regions 23 of the first damping band 105 and the second damping band 106 respectively generate larger deformation and have enough storage space for wrinkles, and the extrusion of the damping bands due to the wrinkles is reduced. Moreover, under the condition of large temperature difference between winter and summer, the elastic strength of the damping band can be correspondingly changed due to the expansion and contraction effect and physical properties. The widening of the locking channel allows a larger deformation space for the damping strip. Under the condition that the shell is subjected to accidental electric leakage, the multi-fold deformation of the third width section 23 of the damping band also has an insulation effect, and an umbrella rod held by a user is protected from contacting with current, so that the personal safety of the user is guaranteed. Preferably, the third width zone 23 of the damping strip is formed by weaving a rubber material.

The second width section 22 reduces the edge fold of the damping strip in such a way that the spring force is reduced in the event of a large deformation of the third width section 23. This has the advantage that the damping strip is prevented from slipping down due to extensive deformation. The second width section 22 with moderate hardness can well avoid the phenomenon, and meanwhile, the spaces of the first region, the middle region and the third region corresponding to the second width section 22 are widened again respectively to accommodate the wrinkle parts of the third width sections 23 of the two damping belts respectively.

In conclusion, the form of the locking channel 108 with narrow top and wide bottom and the elastic force setting of the damping band in different areas are properly combined, so that the locking channel has the good technical effects of avoiding slipping, avoiding wrinkles, avoiding extrusion, ensuring long-term use, being water-tight and non-conductive, effectively coping with the effects of expansion with heat and contraction with cold when used outdoors and the like.
