Description

Belt combining device of backpack buffer

Technical Field

The utility model relates to a knapsack buffer specifically does not need other instruments to the area of one-touch knapsack buffer that assembles the knapsack buffer on knapsack area combines the device.

Background

The backpack bumper shown in fig. 1 is used as background technology. The backpack cushion is a useful technique for absorbing impact of a backpack and reducing load applied to a body when walking. When the backpack buffer is combined on the backpack belt without unfastening the backpack belt, the backpack belt needs to be placed on the main body of the backpack buffer, and then the user directly connects the combining device with force. Further, since a tool such as a bolt or an iron pin is used, a screwdriver or the like is used.

On the other hand, most persons have not only one backpack but also various backpacks according to the use, and the backpack cushion is detached from the backpack in use as required and assembled to other backpacks for use.

Even if the backpack buffer distributes corresponding tools, the backpack buffer is easy to lose when being placed at home, so that when the backpack buffer needs to be detached and installed on other backpacks, a proper tool cannot be found for a while, and even the backpack buffer needs to spend time to buy again. Also, to solve these problems, some people buy a plurality of backpack cushions to be installed separately for each backpack, thereby causing waste.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model provides a belt combining device of a backpack buffer, which is characterized in that when the backpack buffer is combined on a backpack belt, the backpack belt does not need to be untied, other tools are not needed, and the backpack buffer can be simply combined on the backpack belt in a one-touch mode.

Therefore, the utility model discloses a knapsack buffer's area binding apparatus, according to the knapsack buffer, include: a main body and a band coupling bar; the main body comprises a moving assembly with a belt combining frame, wherein the belt combining frame comprises a rod hole which can combine a belt combining rod on two walls and a rod channel which is connected with the rod hole and enables the belt combining rod to pass through; the band coupling bar includes: a fixing frame for pressing the backpack strap, a cylindrical bar ridge whose one surface is cut to enable the bar channel of the main body to pass through and then be combined with the bar hole, and a bar wing convenient for rotating by hand.

Optionally, the belt coupling frame of the main body further includes a locking hole; and the belt connecting rod is also provided with a clamping ridge.

As described above, the belt coupling device of the backpack buffer according to the present invention has the advantages that no other tools are required, and the backpack buffer can be detached from a backpack and then assembled to another backpack, so that the backpack buffer is convenient and can be used with a plurality of backpacks in a matching manner to achieve the effect of saving resources.

Detailed Description

The present invention configured as described above is described in detail below with reference to the accompanying drawings. As shown in fig. 2, the present invention is composed of two parts, specifically, a backpack cushion body 10 with a built-in spring and a strap connecting rod 20 lever-connected to the body to fix the backpack strap to the body.

The main body 10 is as shown in fig. 3, and has a structure including: the middle assembly 11 with built-in buffer spring and the bidirectional moving assembly 12 connected with the middle assembly 11 by the buffer spring respectively, and each moving assembly 12 is provided with a belt connecting frame 13 capable of connecting a backpack belt. When the harness coupling rod 20 is coupled after the harness straps are arranged on the strap coupling frame, the harness straps are fixed. In the tape coupling frame, in order to fix the tape coupling bar, bar holes 14 are formed in both walls thereof. The inside of the rod hole is provided with a tunnel-type rod passage 15 connected to the rod hole so that a rod ridge 23 of the band coupling rod 20 passes through. The rod channel is narrower than the rod bore 14. Because the bar sill with the combined bar can not be separated from the main body when rotating 90 degrees after passing through the narrower bar channel.

In contrast, the tape connecting frame has engaging holes 16 formed in both walls thereof for preventing the tape connecting rod from being rotated reversely.

As shown in fig. 3 and 4, the band coupling bar 20 includes: a strap fixing frame 21 capable of pressing the backpack strap; and a wing 22 bent at 90 degrees to facilitate rotation by hand; and a lever sill 23 passing through the lever passage 15 of the main body and then coupled to the lever hole; and a locking ridge 24 corresponding to the locking hole of the main body for preventing the tape connecting rod from being reversed. The lever ridges 23 are protruded from both ends of the belt fixing frame in a cylindrical shape with one surface cut.

The clamping ridges are protruded from two ends of the rod wing, and the width between the two clamping ridges is slightly smaller than the width of the inner sides of two walls of the main body belt combining frame.

Example 1:

according to the embodiment of the present invention, as shown in fig. 5 and 7, after the backpack strap 30 is placed on the strap coupling frame 13 of the main body, the strap coupling rod 20 is vertically erected, and then the rod ridge 23 is inserted into the rod passage 15 of the main body, and when the backpack strap is rotated by 90 degrees, as shown in fig. 6 and 7, the strap fixing frame 21 with the strap coupling rod strongly presses the backpack strap, so that the backpack strap is fixed on the main body. At this time, the stem ridge 23 is formed in a cylindrical shape having an original width and is wider than the stem passage 15, and thus cannot be freely separated from the main body. In addition, the engagement ridge 24 is placed in the engagement hole 16 to prevent the tape coupling lever from rotating freely.

When this is done in the reverse order, the strap engaging bar is easily removed.

The utility model adopts the above technique, can need not use special instrument anytime and anywhere, also can lift the knapsack buffer off on the knapsack or assemble, not only solved awkward problem, can also resources are saved, can be said to be a useful technique.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
