Description

Technical Field

[0001] The utility model relates to an object carrier, in particular to an object carrier used as a jack accessory. Background Art

[0002] In the United States, there is a clear market demand for trailer RVs. As the best tool for outdoor camping, trailer RVs are popular among outdoor sports enthusiasts. The use of trailer RVs is inseparable from the jack. Since the towing vehicle cannot provide stable support for a long time, the jack must be used to provide independent and stable support to the trailer RV. The jack has a telescopic component and a load-bearing component. The telescopic component includes an outer tube, and the load-bearing component is fixed to the outer tube by welding; the load-bearing component is connected to the frame of the trailer RV. The height of the trailer RV is generally more than two meters. When it is necessary to work on the side or top of the trailer RV, it is often necessary to use a ladder or climb to the roof to solve the problem. This kind of climbing operation is temporary. If a ladder is always prepared to meet the temporary climbing needs, or the operation is carried out in an unsafe way, it will inevitably bring storage requirements or safety hazards. Summary of the invention

[0003] The technical problem to be solved by the utility model is how to implement temporary climbing work, thereby obtaining an object carrying device.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: the object carrier is provided with a tube sleeve component, a carrier component, and a clamping component; the tube sleeve component is provided with a through-type accommodating hole, the cross section of the accommodating hole is a regular hexagon, the object carrier is located outside the tube sleeve component and is used for load-bearing operations, the clamping component includes a limiting column, a spring, and a handle; the tube sleeve component is provided with a mounting hole, the cross section of the mounting hole along the center line of the mounting hole is convex, the diameter of one end of the mounting hole is smaller than the diameter of the other end of the mounting hole, the limiting column is located in the mounting hole, and the limiting column Slidingly connected to the tube sleeve component, the limit column has a convex cross-section along the center line of the limit column, one end of the limit column passes through the spring and is located outside the tube sleeve component, the spring is located between the limit column and the tube sleeve component, the handle is fixedly installed at one end of the limit column and is located outside the tube sleeve component, the loading component is fixedly installed on one side of the tube sleeve component, and the handle is located on the other side of the tube sleeve component, the other end of the limit column extends into the accommodating hole, the center line of the limit column is perpendicular to one side of the cross-section of the accommodating hole, and the center line of the accommodating hole intersects with the center line of the limit column.

[0005] The object carrier can be used as an accessory of the jack, or it can replace the original load-bearing structure of the jack and be used in combination. The outer tube of the jack is generally cylindrical, and the receiving hole of the pipe sleeve component is used to accommodate the outer tube of the jack. The limit column on one side of the outer tube is pressed on the outer tube, and at least one contact position is formed between the outer tube and the pipe sleeve component on the other side of the outer tube. When the object carrier is not loaded, the center line of the receiving hole coincides with the center line of the outer tube, and the contact position exists in a line contact manner. The relative static position relationship between the object carrier and the outer tube is maintained by friction; after the object carrier is loaded, the posture of the object carrier on the jack is tilted, the contact position exists in a point contact manner, and other contact positions are added in a point contact manner. The relative static position relationship between the object carrier and the outer tube is still maintained by friction, but the friction force generation position changes at this time, and the friction force becomes greater. If the outer tube of the jack is a hexagonal tube, when the limit column is pressed on the outer tube, at least one contact position is formed between the outer tube and the pipe sleeve component. When the object carrier is not loaded, the center line of the receiving hole coincides with the center line of the outer tube, the contact position exists in surface contact, and the object carrier and the outer tube maintain a relatively static position relationship through friction; when the object carrier is loaded, the posture of the object carrier on the jack tilts, the contact position changes from surface contact to line contact, and other contact positions are added in point contact. The object carrier and the outer tube still maintain a relatively static position relationship through friction, but the friction force is generated at this time. The location has changed and the friction force has become greater. Obviously, in this technical solution, the connection structure that can generate greater friction is obtained by reducing the spatial morphology of the contact position.

[0006] The load-carrying part is one of the structures of a pedal, a footrest, and a connector with a quick-release structure. The connector is provided with a round hole, which is convenient for directly inserting a log outdoors into the round hole to obtain a climbing structure equivalent to a pedal, and the climbing height remains relatively unchanged. It can also be a turntable with a rotating function, and there are screw holes on the turntable. The logs that are readily available outdoors can be directly fixed on the turntable by screws. After the logs are placed in an inclined posture, a climbing structure with a continuously changing height is obtained. By adding loads to the outside of the jack, a foot-stepping structure can be provided for temporary climbing operations.

[0007] The limiting column is used to apply pressure to the outer tube of the jack, so as to establish a close connection between the outer tube of the jack and the pipe sleeve component. In order to improve the smoothness of the sliding of the limiting column on the pipe sleeve component, the present technical solution provides two structures that facilitate the sliding of the limiting column. In addition to the above-mentioned limiting column obtaining a sliding structure in the mounting hole, it also has such a sliding structure, the handle is provided with an assembly hole, one end of the limiting column is embedded in the assembly hole, the handle and the limiting column are connected by a pin shaft, the handle is provided with a guide sleeve, the pipe sleeve component is provided with a guide column on the outside, the mounting hole is located in the guide column, the guide column extends into the guide sleeve, and the guide sleeve is slidably connected to the guide column. Thus, another structure that facilitates the sliding of the limiting column is obtained through the guide column and the guide sleeve.

[0008] In order to expand the application scope of the object carrier, a through auxiliary hole is provided inside the sleeve component, the cross section of the auxiliary hole is rectangular, the auxiliary hole is connected to the receiving hole, the length of the long side of the cross section of the auxiliary hole is equal to the side length of the cross section of the receiving hole, and the other end of the limit column extends into the receiving hole after passing through the auxiliary hole. With the auxiliary hole, the relative swing amplitude of the outer tube of the jack in the receiving hole will be appropriately increased, which can help increase friction, thereby adapting to the outer tube of the jack with different surface hardness.

[0009] In order to prevent foreign matter from hindering the movement of the guide sleeve, the pipe sleeve component is provided with a retaining ring, and the guide sleeve is located inside the retaining ring. The retaining ring wraps the guide sleeve to prevent foreign matter from appearing in the range of movement of the guide sleeve.

[0010] The utility model adopts the above technical solution: the load is attached to the jack through friction and provides a support structure suitable for personnel to climb. By adding loads outside the jack, a foot-stepping structure can be provided for temporary climbing operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1 , 2 3 shows the first embodiment of the utility model. The object carrier is provided with a tube sleeve component 1, an object carrier component 2, and a clamping component.

[0018] The pipe sleeve component 1 is a tubular structure as a whole. The pipe sleeve component 1 is provided with a through-type receiving hole 3 and a through-type auxiliary hole 4. The cross section of the receiving hole 3 is a regular hexagon, and the cross section of the auxiliary hole 4 is a rectangle. The auxiliary hole 4 is connected with the receiving hole 3. The length of the long side of the cross section of the auxiliary hole 4, i.e., the side length, is equal to the side length of the cross section of the receiving hole 3, and the long side of the cross section of the auxiliary hole 4 coincides with one side of the cross section of the receiving hole 3.

[0019] A guide column 5 and a retaining ring 6 are provided outside the pipe sleeve component 1. The guide column 5 is cylindrical in shape as a whole, and a mounting hole 7 is provided on the pipe sleeve component 1. The mounting hole 7 is located inside the guide column 5, and the center line of the mounting hole 7 coincides with the center line of the guide column 5. The retaining ring 6 is tubular in shape as a whole, and is located outside the guide column 5, and the retaining ring 6 is spaced from the guide column 5; the center line of the retaining ring 6 coincides with the center line of the guide column 5.

[0020] The mounting hole 7 is divided into two parts, one part is a cylindrical shape with a shorter length and a smaller diameter, and the other part is a cylindrical shape with a longer length and a larger diameter. The mounting hole 7 is convex in cross section along the center line of the mounting hole 7, and the pipe sleeve component 1 forms a step surface at the mounting hole 7, so the diameter of one end of the mounting hole 7 is smaller than the diameter of the other end of the mounting hole 7. The clamping component includes a limiting column 8, a spring 9, and a handle 10. One part of the limiting column 8 is a cylindrical shape with a shorter length and a smaller diameter, and the other part is a cylindrical shape with a longer length and a larger diameter. The limiting column 8 is convex in cross section along the center line of the limiting column 8, and a step surface is formed between the two ends of the limiting column 8 with different diameters; therefore, the diameter of one end of the limiting column 8 is smaller than the diameter of the other end of the limiting column 8. The outer shape of the limiting column 8 corresponds to the structure of the mounting hole 7. When the limiting column 8 is installed in the mounting hole 7, the limiting column 8 can slide on the pipe sleeve component 1. The spring 9 is sleeved on the limiting column 8. After installation, one end of the limiting column 8 passes through the spring 9 and is located outside the pipe sleeve component 1. One end of the spring 9 is blocked by the limiting column 8, and the other end of the spring 9 is blocked by the pipe sleeve component 1, so that the spring 9 is located between the limiting column 8 and the pipe sleeve component 1. After installation, the center line of the limiting column 8 is perpendicular to one side of the cross section of the receiving hole 3, and the center line of the receiving hole 3 intersects the center line of the limiting column 8 perpendicularly.

[0021] The handle 10 is T-shaped as a whole, and is divided into a hand-holding part and a connecting part. One end of the connecting part is connected to the hand-holding part, and the connecting part is perpendicular to the hand-holding part. An assembly hole is provided at the connecting part, and the assembly hole corresponds to the limit column 8. When connected, one end of the limit column 8 is embedded in the assembly hole, and then the handle 10 and the limit column 8 are connected by a pin shaft; after installation, the handle 10 is located outside the sleeve component 1. The other end of the connecting part extends outward to form a guide sleeve 11 of a tubular structure, and the aperture inside the guide sleeve 11 is larger than the aperture of the assembly hole. The guide column 5 extends into the guide sleeve 11 and the guide sleeve 11 is slidably connected to the guide column 5. The guide sleeve 11 is also located between the retaining ring 6 and the guide column 5. In the initial state, the guide sleeve 11 is located inside the retaining ring 6, and the spring 9 is in a compressed state. The spring 9 always pushes the limit column 8, so that the other end of the limit column 8 passes through the auxiliary hole 4 and then extends into the receiving hole 3, and the guide sleeve 11 extends to the innermost position of the area between the retaining ring 6 and the guide column 5, until the guide sleeve 11 of the handle 10 is blocked by the pipe sleeve component 1. The carrier component 2 is fixedly connected to the pipe sleeve component 1, and the carrier component 2 is located outside the pipe sleeve component 1. The carrier component 2 is fixedly installed on one side of the pipe sleeve component 1, and the handle 10 is located on the other side of the pipe sleeve component 1. In this embodiment, the carrier component 2 is a pedal, and a wavy anti-slip structure is provided on the top of the carrier component 2.

[0022] The object carrier is placed on a rod-shaped support structure or a jack. This embodiment takes the combined use of the object carrier and the jack as an example. The jack is provided with an outer tube, and the cross-sectional profile of the outer tube is circular. The outer tube of the jack passes through the receiving hole 3 of the tube sleeve component 1 of the object carrier. In the clamping component, the spring 9 pushes the limit column 8 to squeeze the outer tube toward one side of the outer tube, and the spring 9 simultaneously applies a force to the tube sleeve component 1 to drive the tube sleeve component 1 to squeeze the outer tube toward the other side of the outer tube. At this time, the tube sleeve component 1 has a contact position Ⅰ12 with the outer tube at the receiving hole 3, and the contact position Ⅰ12 is a line contact mode, and there is a contact position Ⅱ13 between the limit column 8 and the outer tube, and the contact position Ⅱ13 is a point contact mode. In the initial state, the limiting column 8 and the pipe sleeve component 1 squeeze the outer tube by the elastic force of the spring 9, and the load is fixed on the jack by the friction between the limiting column 8 and the outer tube, and the friction between the pipe sleeve component 1 and the outer tube, and the center line of the receiving hole 3 is parallel to the center line of the outer tube. Figure 4As shown, when in use, the object-carrying component 2 bears the load, and the object-carrying component is only subjected to force on one side, causing the object-carrying component to tilt relative to the outer tube; on one side of the outer tube, the original line contact position Ⅰ12 becomes point contact, and the contact position Ⅰ12 moves down to the bottom of the receiving hole 3 of the tube sleeve component 1. On the other side of the outer tube, that is, the side of the outer tube facing the auxiliary hole 4, the top of the tube sleeve component 1 supports the outer tube, thereby adding two contact positions Ⅲ14 in the form of point contact. The relative static position relationship between the object-carrying component and the outer tube is still maintained by friction, but the friction force generation position has changed and the friction force has become greater. When the load disappears, the spring 9 will cause the tube sleeve component 1 to return to its initial state.

[0023] If the outer diameter of the outer tube is small, in the initial state, the sleeve component 1 has a contact position IV15 with the outer tube at the receiving hole 3, and the contact position IV15 is a line contact mode; Figure 5 As shown, after the load-bearing component 2 bears the load, the contact position IV15 eventually moves down to the bottom of the accommodating hole 3 of the sleeve component 1, and forms a contact position IV15 in a point contact manner. On the other side of the outer tube, that is, the side of the outer tube facing the auxiliary hole 4, the outer tube is partially embedded in the auxiliary hole 4, and the sleeve component 1 presses against the outer tube at the top of the auxiliary hole 4, thereby forming two contact positions V16 in a point contact manner.

[0024] The second embodiment of the utility model is different from the first embodiment in that the tube sleeve component does not have an auxiliary hole. When the outer diameter of the outer tube is small, after the load-bearing component bears the weight, the top of the tube sleeve component presses against the outer tube on the other side of the outer tube, that is, the side of the outer tube facing the limit column, thereby forming a contact position in a point contact manner.

[0025] The structure of the object-carrying component in the above-mentioned embodiment can also be one of the structures of a pedal, a turntable, and a connector with a quick-release structure. The pedal is a flat plate-shaped structure. The turntable is fixed to the pipe sleeve component in a movable manner. The turntable has a rotation function and can rotate relative to the pipe sleeve component. There are screw holes on the turntable, and a long log readily available outdoors can be directly fixed to the turntable by screws. One end of the log is connected to the object-carrying component and is in a higher position, and the other end of the log directly touches the ground. In this way, after the log is placed in an inclined posture, a climbing structure with a continuously changing height is obtained. The connector is provided with a round hole, which is convenient for directly using a short log outdoors to be inserted into the round hole to obtain a climbing structure equivalent to a pedal.
