Description

Technical Field

[0001] The utility model relates to the technical field of hanging type storage racks, in particular to an electronic weighing device arranged on a force-bearing rope of a hanging rope storage rack. Background Art

[0002] The rope rack is also called the ceiling rack. Generally, the rope is installed on the indoor ceiling by fixing parts. The bottom end of the rope is connected to several corners of the storage board, such as the four corners of the rectangular storage board. Some can also use a manual drive device or an electric drive device to drive the storage board to rise or fall for the convenience of placing or taking things. The rope includes a force rope and a spare rope for safety. The connection relationship of the spare rope is basically the same as that of the force rope, but the spare rope is not under force. The force rope is also called a force rope, and the spare rope is also called a spare rope. The rope rack has been widely promoted and applied because it can reasonably utilize the indoor height space.

[0003] However, the existing rope storage rack cannot automatically weigh items during normal placing or taking out of items, so that users cannot intuitively understand the weight of the items placed, thereby posing a potential safety hazard due to overweight of the items placed.

[0004] Although there are many electronic scales or electronic weighing devices for ropes in the prior art, they all place the sensor components electrically connected to the controller and the display screen between the object to be weighed and the end of the rope, and measure the data when the two ends are pulled. The electronic scales or electronic weighing devices for ropes in the prior art all need to set a fixing device or a connecting device between the sensor components and the object, and their structures are relatively complex, and the connection and fixing are relatively cumbersome. Moreover, if the electronic weighing devices for ropes are used for long-term weighing of rope racks, there is a safety hazard that the ropes may become loose and slip.

[0005] The electronic scales or electronic weighing devices for ropes in the prior art cannot automatically weigh the ropes while keeping the ropes intact and the rope racks are in the normal process of placing or taking out objects. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an electronic weighing device which is relatively simple in structure and can be arranged on the force rope of the rope rack, and can automatically weigh the rope while the rope rack is kept intact during normal placing or taking out of objects.

[0007] The technical solution of the utility model is to provide an electronic weighing device arranged on the force rope of the rope storage rack, including a shell, a display screen arranged at the window of the shell, a controller placed in the shell, a battery and a pressure sensor, the controller is electrically connected to the pressure sensor and the display screen, and the battery is electrically connected to the pressure sensor, the controller and the display screen; the upper end and the lower end of the shell are both provided with openings for the force rope to pass through, the shell is provided with an arc-shaped receiving groove which is communicated with the opening through which the force rope passes and is used to embed the force rope, the inner side wall of the arc-shaped receiving groove is provided with a notch which is communicated with a transverse straight receiving groove, the outer end surface of the contact of the pressure sensor in the transverse straight receiving groove protrudes from the inner side wall of the arc-shaped receiving groove, and is always pressed by the inner side surface of the force rope in the arc-shaped receiving groove.

[0008] After adopting the above structure, the electronic weighing device of the utility model arranged on the force rope of the rope storage rack has the following advantages: the structure is relatively simple, and the connection with the force rope such as the force wire rope is very convenient. It is only necessary to embed the openings and arc-shaped receiving grooves through which the force ropes at the upper and lower ends of the electronic weighing device pass into any section of the force rope in the vertical or force-bearing rope, so that the section of the force rope is arc-shaped and the inner side of the force rope is always pressed on the outer surface of the contact of the pressure sensor in the horizontal straight receiving groove, so that automatic weighing is always maintained during the normal placing or taking of objects on the rope storage rack. Because the force rope embedded in the arc-shaped groove presses the contact of the pressure sensor, in other words, the force rope is always limited or stuck by the contact of the pressure sensor, and the force rope will not be disengaged from the arc-shaped groove, nor will it be disengaged from the electronic weighing device. The electronic weighing device relies on the lateral pressure of a force rope such as a steel wire rope to measure the weight of items on the storage board. Its structure is relatively simple, and the connection and fixing is relatively convenient and trouble-free. Moreover, since the force rope does not need to be disconnected for automatic weighing, the safety hazard of the rope loosening and slipping is avoided. The electronic weighing device set on the force rope of the rope storage rack can automatically weigh while keeping the rope intact and the rope storage rack in the normal process of placing or taking out items, so that the user can intuitively understand the weight of the items placed on the storage board of the storage rack at any time, thereby avoiding the safety hazard caused by the overweight of the items placed on the storage board of the storage rack.

[0009] Furthermore, the outer end surface of the contact of the pressure sensor is an arc surface that matches the arc surface of the inner side surface of the force rope in the arc-shaped placement groove. After adopting the above structure, the inner side surface of the force rope such as the force wire rope directly contacts the contact of the pressure sensor with a larger contact area, and the accuracy of automatic weighing is higher.

[0010] Furthermore, the width of the upper and lower ends of the shell is smaller than the width of the middle of the shell height, and the two sides of the shell are convex arcs that are wide in the middle of the height and narrow at both ends; the arc-shaped placement groove that can be directly embedded on the force rope without obstruction and the openings through which the force ropes at both ends pass are both located on one side of the shell. After adopting the above structure, the reliability and stability of the inner side of the force rope in the arc-shaped placement groove directly contacting with the contact of the pressure sensor are better, further ensuring the technical effect of keeping the suspension rope such as the force rope intact and the suspension rope rack automatically weighing with high precision during the normal placing or taking process.

[0011] Furthermore, the shell includes a main body and a cover body fixed to the main body, the main body is provided with an arc-shaped receiving groove, an opening through which the force ropes at both ends pass, a transverse straight receiving groove for accommodating a pressure sensor, a battery cavity for accommodating a battery, and a window fixed with a display screen, and the cover body covers the rest of the main body except the arc-shaped receiving groove and the opening through which the force ropes at both ends pass. With the above structure, the pressure sensor, controller, display screen, battery and other components of the device are easy to install, and the cover body can prevent dust and the like from entering the main body. If a detachable fixation is adopted, the inspection and replacement of components are more convenient.

[0012] Furthermore, the controller and the display screen are integrated into a controller display unit. After adopting the above structure, the integration of components is relatively improved, material costs are relatively saved, and installation efficiency is relatively improved.

[0025] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these specific implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each specific implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown.

[0027] The rope storage rack 1 of the prior art is also called a ceiling storage rack. Generally, a fixing member 11 is used to install a rope 12 on the ceiling of the room. The bottom end of the rope 12 is connected to several corners of a storage board 13, such as the four corners of a rectangular storage board. A manual drive device 14 or an electric drive device can also be used to drive the storage board 13 to rise or fall for the convenience of placing or taking things. The rope 12 includes a force rope 121 such as a force wire rope. For the sake of greater security and safety, the rope 12 includes a set of force ropes 121 such as a force wire rope, and also includes a set of spare ropes 122 such as a spare wire rope. The connection relationship of the spare rope 122 is the same as that of the force rope 121. The spare rope 122 can also be used to rise or fall the storage board 13. However, the spare rope 122 is generally not subjected to force during use and only serves as a backup. If one or several force ropes 121 break due to various reasons, the spare rope 122 can still ensure safety. It is not difficult to understand that the electronic weighing device is only set on the force rope 121, but not on the spare rope 122. For example, if the electronic weighing device is set on the force rope 121 of a pair of suspension ropes 12, the spare rope 122 of the same section will be bent without being stressed. For multiple suspension ropes 12, such as the four suspension ropes 12 of the rectangular storage plate, an electronic scale or an electronic weighing device can be set on one or two force ropes 121. The force rope 121 can also be called the force rope, and the spare rope 122 can also be called the spare rope. In addition to the wire rope, the suspension rope can also be a nylon rope and other fiber ropes such as hemp rope, palm rope, etc.

[0028] The electronic weighing device of the utility model disposed on the force rope of the rope storage rack comprises a housing 2, a display screen 51 disposed at a window 212 of the housing 2, a controller disposed in the housing 2, a battery 3 and a pressure sensor 4, the controller is electrically connected to the pressure sensor 4 and the display screen 51, and the battery 3 is electrically connected to the pressure sensor 4, the controller and the display screen 51. It is not difficult to understand that the window 212 can be a through hole such as a rectangular through hole, but can also be a transparent plate flush with the surface of the body 21 described below.

[0029] The upper and lower ends of the shell 2 are provided with openings 213 through which a force rope 121, such as a force wire rope, passes. The shell 2 is provided with an arc-shaped receiving groove 214 which is communicated with the opening 213 through which the force rope 121 passes and is used to embed the force rope 121, such as a force wire rope. The inner side wall 2141 of the arc-shaped receiving groove, or the inner partition, is provided with a notch 215, and the notch 215 is communicated with a transverse straight receiving groove 216. The outer end face of the contact 41 of the pressure sensor 4 in the transverse straight receiving groove 216 protrudes from the inner side wall 2141 of the arc-shaped receiving groove, as described below, and is always pressed by the inner side face 1211, or the inner side, of the force rope 121 in the arc-shaped receiving groove 214. That is, the inner side surface 1211 of the force rope 121 in the arc-shaped placement groove 214, such as the force rope, and the outer end surface of the contact 41 of the pressure sensor 4, such as the arc-shaped surface 411 described below, always abut against each other. In other words, the electronic weighing device automatically weighs the objects while keeping the rope 12, such as the force rope 121, intact and the placement plate 13 of the rope placement rack 1 in the normal process of placing or taking objects. It is not difficult to understand that even if there is no object on the placement plate 13 temporarily, the electronic weighing device is still weighing the weight of the placement plate 13, because the placement plate 13 has its own weight. After placing the objects, the total weight minus the weight of the placement plate is the weight of the placed objects.

[0030] The inner end 42 of the pressure sensor 4 abuts against the bottom wall of the transverse straight receiving groove, and the outer end of the pressure sensor is the contact 41 of the pressure sensor 4 which is always pressed by the inner side surface 1211 of the force-bearing rope 121 in the arc-shaped receiving groove 214 .

[0031] Preferably, the outer end surface of the contact 41 of the pressure sensor 4 is an arcuate surface 411 matching the arcuate surface of the inner side surface 1211 of the force-bearing rope in the arcuate groove 214 .

[0032] The pressure sensor 4 can be a transverse Z-shaped pressure sensor. Of course, the pressure sensor can also be a spring-type pressure sensor.

[0033] The width of the upper end and the lower end of the shell 2 is smaller than the width of the middle of the height of the shell 2, and the two sides of the shell 2 are convex arcs 217 that are wide in the middle of the height and narrow at both ends. It is not difficult to understand that the width of the upper end and the lower end of the body 21 is smaller than the width of the middle of the height of the body 21, and the two sides of the body 22 are convex arcs that are wide in the middle of the height and narrow at both ends. The width of the upper end and the lower end of the cover 22 is smaller than the width of the middle of the height of the cover 22, and the two sides of the cover 22 are convex arcs that are wide in the middle of the height and narrow at both ends.

[0034] The arc-shaped receiving groove 214 that can be directly embedded in the force-bearing rope 121 without any obstruction and the openings 213 through which the force-bearing ropes 121 at both ends pass are both located on one side of the shell 2, such as one side of the body 21 described below.

[0035] The housing 2 preferably includes a body 21 and a cover 22 fixed to the body 21. The body 21 is preferably provided with an arc-shaped receiving groove 214, an opening 213 through which the force ropes 121 at both ends pass, a transverse straight receiving groove 216 for accommodating the pressure sensor 4, a battery cavity 218 for accommodating the battery 3, and a window 212 to which the display screen 51 is fixed, and the cover 22 covers the rest of the body except the arc-shaped receiving groove 214 and the opening 213 through which the force ropes 121 at both ends pass. The opening 213 through which the force ropes 121 pass mentioned above can also be understood as the opening 213 for accommodating the force ropes 121.

[0036] The cover body and the body mentioned above can be fixed by detachable connection, such as the cover body and the body are fixed by male and female snaps. It is also possible to provide a plurality of screw holes on the cover body and a plurality of corresponding threaded holes on the body, and to tighten the screws through their respective screw holes one by one in the threaded holes. Of course, if the cover body only covers components such as pressure sensors, batteries, controllers and display screens, and the above components generally do not need to be replaced, the cover body and the body mentioned above can also be fixed by adhesive bonding. Of course, it is preferred that the cover body and the body are detachably connected and fixed.

[0037] Of course, in order to be more stable and reliable, after the load-bearing rope is embedded in the arc-shaped receiving groove, a plurality of pressure blocks or one or more pressure strips can be provided on the outer surface of the arc-shaped receiving groove to prevent the load-bearing rope, such as the load-bearing steel wire rope, from escaping from the arc-shaped receiving groove, or the cover body can be designed to cover the width of the arc-shaped receiving groove, and a detachable connection and fixation such as a screw, a screw through hole and a threaded hole screw connection structure can be adopted.

[0038] The controller may be a MCU, i.e., a control chip. The display screen 51 is also referred to as a display unit. Of course, the controller, such as an MCU, and the display screen 51 may be integrated into a controller display unit 5. The controller display unit 5 may be fixed to the body 21 on the inner side of the window 212, such as by screwing or gluing.

[0039] The battery cavity 218 may be a vertical rectangular shape, and two batteries 3 may be placed side by side in the vertical rectangular battery cavity 218 .

[0040] The electrical connection can be made by wire connection, and through holes for the wires to pass through can be provided on the bottom plate of the horizontal straight receiving groove 216, that is, on the vertical side partition 2181 of the battery cavity 218 and on the upper end partition 2182 of the battery cavity 218.

[0041] When in use, the openings 213 and the arc-shaped receiving grooves 214 at the upper and lower ends of the housing 2 of the electronic weighing device, such as the main body 21 covered with the cover 22, are embedded in any section of the stressed or vertical stressed rope 121, such as a stressed steel wire rope, so that the inner side of the stressed rope 121, such as the stressed steel wire rope, always presses the arc-shaped surface 411 of the contact 411 of the pressure sensor 4. One electronic weighing device can be set on one of the multiple stressed ropes 21, such as four, or one electronic weighing device can be set on each of the multiple stressed ropes 121, such as two of the four.

[0042] The above unmarked parts, structures or quantities are not shown in the drawings. The drawings are for illustration only. If there is any inconsistency between the drawings and the text description or between the drawings, the text description shall prevail.

[0043] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
