Description

Technical Field

[0001] The utility model relates to the technical field of bags and suitcases, and in particular to a stable bag and suitcase weighing handle. Background Art

[0002] During air travel, there is often the problem of overweight luggage, which requires either paying overweight fees or taking out excess items from the suitcase. This causes inconvenience to travelers, and in order to solve this problem, suitcases with weighing functions have emerged.

[0003] For example, the prior art CN208488158U uses a weighing sensor, which is arranged inside the handle. The sensor part is connected to the box body, and part is connected to the handle. When the handle is lifted, the sensor is deformed, thereby generating a change in the electrical signal, and then calculating the weight of the suitcase, thereby achieving the purpose of convenient and fast weighing.

[0004] However, this kind of design has a flaw, that is, when the weighing sensor and the handle apply upward lifting force, a part of the sensor and the handle are connected by screws. This design structure has a flaw after long-term use by users. Because the suitcase is under stress and shakes for a long time during use, the screws may become loose or even loose, which leads to two problems. If the screws are loose, the weighing may be inaccurate, and if they are loose, the function will be completely lost. (See attached Figure 1 ) The weighing principle is that when the pin is forced upward, the sensor will be pulled upward through the screw to deform it. For example, at the height of h1, the sensor is in the normal state. From the h1-h2 stage, the sensor is in the deformation stage, and the accurate value appears at h2. If the screw is loose, the pin will be in the h2-h3 stage. At this time, the weight of the bag is borne by the sensor and the handlebar seat respectively. If the screw is completely detached, the pin will be at the top h3 position of the slide, and the weight of the bag will be completely borne by the handlebar seat, and the sensor will lose its function.

[0005] Therefore, a simpler and more stable structural design is needed to solve this problem so that the connection between the weighing sensor and the handle will not be easily detached. Summary of the invention

[0006] The purpose of the utility model is to solve the above defects and provide a stable luggage weighing handle, which utilizes a special structure to solve the instability problem in the prior art, thereby achieving the purpose of stable connection between the sensor and the handle.

[0007] The purpose of the utility model is achieved by the following methods:

[0008] A stable luggage weighing handle includes a bottom cover and a handle seat arranged inside the bottom cover, the handle seat and the bottom cover are fixedly connected, a sensor is arranged on the handle seat, and is used to sense the weight of the luggage when the handle is lifted, a hook is arranged inside the handle seat, and the hook surface at the bottom of the hook supports the force-bearing end of the sensor, and is used to stably apply an upward pulling force to the sensor, and the handle is connected to the upper end of the hook, and is used to lift the entire luggage. In order to avoid the defects of the prior art, this design adopts a hook structure to hold the gravity sensor from the bottom to the top, thereby ensuring the reliability of the entire structure, and its overall structure is more stable.

[0009] In the above description, as a preferred solution, the sensor includes a fixed part, a force-bearing end and a sensing chip. The fixed part and the handle seat are fixedly arranged, a strip-shaped force-bearing end extends from the fixed part, the sensing chip is tightly attached to the force-bearing end, and the hook surface of the hook hooks the lower surface of the force-bearing end from bottom to top. The strip-shaped force-bearing end reacts more obviously when it is deformed by force, so the feedback accuracy of the sensing chip is higher than that of the block structure. And it is more conducive to the hook to cooperate with it.

[0010] The first technical solution of the hook is that the hook is a U-shaped structure, consisting of a hook surface and two cantilevers, and the top of the cantilever is provided with a hook head bent downward. The hook surface is hung on the force-bearing end from below, and when the hook surface is forced upward, it drives the sensor to deform. This structure is simple, effective and stable. The two cantilevers apply tension from both sides at the same time, and the tension is also relatively uniform. The hook head at the top is used to engage with the pin shaft. When the handle is pulled upward, the pin shaft drives the hook head to move upward.

[0011] In the above description, as a preferred solution, the hook surface is provided with a screw hole, and the corresponding force-bearing end is also provided with a screw hole, and the two correspond to each other. In order to ensure the stability between the hook surface and the sensor, the two are fixed by screws. Although screws are also used here, their purpose is to connect the hook surface and the sensor. The screws do not apply tension, and play a role in further stabilizing the hook surface and the sensor.

[0012] Another design scheme of the hook is a box-shaped structure with an open top, and a hook surface extends downward from the bottom to support the lower surface of the force-bearing end. This box-shaped structure is more stable and the force is more evenly distributed. The upward pulling force is distributed to the four walls of the box body through the box body, which is more solid and has a longer service life. The hook surface extending downward from the box body is used to hold the force-bearing end to achieve the purpose of stability.

[0013] In the above description, as a preferred solution, through-hole-shaped limit grooves are provided on opposite sides of the box-shaped structure, and the limit grooves are inclined from bottom to top to form a hook head. The limit grooves are used to assemble the pin shaft, and the pin shaft realizes the pulling space up and down in the slide groove and the limit groove.

[0014] In the above description, as a preferred solution, a screw hole is provided on the hook surface, and a screw hole is also provided on the corresponding force-bearing end, and the two correspond to each other.

[0015] In the above description, as a preferred solution, the handle is a strip-shaped structure with connecting heads on both ends, the connecting heads are provided with lifting holes, and pins are provided in the lifting holes, and the pins are used to connect with the hooks. The bottom cover is also a strip-shaped structure with corresponding accommodating grooves at both ends for accommodating the handle seat, sensor and connecting head.

[0016] In the above description, as a preferred solution, the handlebar seat is a box-shaped structure with an open upper end, the sensor is installed on the outer side of the bottom of the handlebar seat, and a through hole groove is provided at the bottom of the handlebar seat to expose the force-bearing end and provide space for deformation of the force-bearing end. A slide groove is also provided on the side wall of the handlebar seat, and the height of the top of the slide groove is higher than the height of the hook head.

[0017] In the above description, as a preferred solution, the handlebar seat and the bottom cover are fixedly connected by screws.

[0018] The beneficial effects of the utility model are as follows: in order to avoid the defects of the prior art, the design scheme adopts a hook structure to hold the gravity sensor from the bottom to the top, thereby ensuring the reliability of the entire structure and making the overall structure more stable.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The purpose of the utility model is achieved by the following methods:

[0036] A stable luggage weighing handle, the structure of which includes

[0037] According to the shortcomings described in the background technology, a stable luggage weighing handle is designed, including a handle 1, a handle seat 2, a sensor 3, a hook 4, a pin 5, a bottom cover 6, a display 7, a screw 8 and a luggage wall 9. The luggage wall 9 provides an installation basis for the weighing handle parts, and the bottom cover 6 is fixedly installed on the inner layer of the luggage wall 9. The bottom cover 6 is also provided with a receiving groove 601, which is used to provide an installation basis for the handle 1, the handle seat 2 and other parts. A through hole is provided on the bag at a position corresponding to the accommodating groove 601, which is convenient for the installation of the handlebar seat 2. The handlebar seat 2 is connected and fixedly installed on the inside of the bottom cover 6 from bottom to top by screws, providing an installation basis for the hook 4 and the pin 5. A through hole groove 202 is also provided at the bottom of the handlebar seat 2 to expose the force-bearing end 301. A slide groove 203 is also provided on the side wall of the handlebar seat 2. The slide groove 203 provides a movable space for the movement of the pin 5. A buckle 201 is also provided at the bottom of the handlebar seat 2. The buckle 201 snaps the sensor 3 to the bottom of the handlebar seat 2.

[0038] The handle 1 is a strip structure, with connectors 101 at both ends, and lifting holes 102 on the connectors. A pin 5 is provided in the lifting holes 102. The pin 5 passes through the handle 1 and is used to connect with the hook head of the hook 4. The pin 5 can move in the slide 203. When the pin 5 moves upward, it drives the hook 4 to move in the same direction. The bottom hook surface 401 of the hook 4 supports the force-bearing end 301 of the sensor 3, which is used to stably apply an upward pulling force to the sensor 3. The hook 4 replaces the function of the traditional screw connection, which solves the problem of loose connection caused by the deformation of the sensor 3 by the screw in the prior art. The pin 5 is connected to the upper end of the hook 4 to help the handle 1 lift the entire bag. The top height of the hook 4 is lower than the top height of the slide 203, so that it can ensure accurate weighing. The sensor 3 is fixedly installed at the bottom of the handle seat 2, and its function is to weigh the weight of the entire bag.

[0039] The sensor 3 structure includes a fixed part 302 and a sensing chip 304. The fixed part 302 is fixedly installed at the bottom of the handle base 2. A strip-shaped force-bearing end 301 extends from the fixed part 302. The sensing chip 304 fits tightly on the force-bearing end 301. The display 7 is fixedly installed at the upper end of the bag wall 9. Its function is to receive the electrical signal from the sensing chip 304 and convert it internally into the weight value measured by the display sensor 3 (this weighing principle is a prior art and is commonly used in electronic scales, so it will not be described in detail here).

[0040] This technical solution adopts two technical solutions of the hook 4.

[0041] In Example 1, the hook 4 is a U-shaped structure, consisting of a hook surface 401 and two cantilevers 403. The top of the cantilever 403 is provided with a hook head 402 that bends downward. The hook 4 has a simple structure, is easy to install and use, is inexpensive, and has a stable and reliable overall structure. The hook surface 401 is hooked on the force-bearing end 301 from below. When the hook surface 401 is forced upward, it drives the sensor 3 to deform. The two cantilevers 403 apply tension from both sides at the same time. The hook head 402 at the top is used to engage with the pin 5. When the handle 1 is pulled upward, the pin 5 drives the hook head 402 to move upward. Thus, the weighing function is realized.

[0042] In Example 1, the hook surface 401 is provided with a screw hole, and the corresponding force-bearing end 301 is also provided with a screw hole, and the two correspond to each other. In order to ensure the stability between the hook surface 401 and the sensor 3, the two are fixed by screws 8, and the screw connection here does not bear force.

[0043] In Example 2, the hook 4 is a box-like structure with an open upper end, and a hook surface 401 extends downward from its bottom to support the lower surface of the force-bearing end 301. The upward pulling force is distributed to the four walls of the box body through the box body, so that the overall force on the handle is evenly distributed and the service life is greatly extended. The hook surface 401 extending downward from the box body is used to hold the force-bearing end 301 to achieve a more stable purpose.

[0044] In Example 2, two opposite sides of the box-like structure are provided with through-hole limiting grooves 404, which are inclined from bottom to top to form hook heads 402. The limiting grooves 404 are used to assemble the pin shaft 5, so that the pin shaft 5 can achieve pulling space up and down in the slide groove 203.

[0045] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
