The operating handle comprises a hollow handle body with a containing groove and an extending handle, wherein the extending handle is telescopically coupled in the containing groove of the hollow handle body so that the extending handle is switched between a storage position and an operating position, wherein when the extending handle is switched to the operating position, the extending handle extends outwards along the containing groove so as to extend the length of the operating handle, so that the arm of force of the operating handle relative to the rotating shaft is prolonged along the operating handle, and the rotating force required by an operator to be applied to the operating handle is reduced. Thus, the operating handle for controlling the movable compact shelf provided by the application has the technical advantages of smaller size and convenience in driving, which are seemingly contradictory.
Description
Technical Field
The present application relates to compact shelving and more particularly to compact shelving and operating handles therefor.
Background
The compact shelf (also called compact cabinet) is mainly used for storing archives, securities certificates and the like, and has the advantages of confidentiality, sealing, high space utilization rate, convenient access and the like. Along with the development of compact shelves, the application of the compact shelves is not limited to the storage of archives, but is more suitable for novel storage equipment for storing books, archives, financial documents and goods in courts, inspection homes, banks, large-scale markets, schools, enterprise institutions, sample rooms and the like.
The movement of the existing compact shelving is generally controlled by means of an operating handle arranged on the side part of the compact shelving. In the process of accessing the archives, the operating handle is rotated clockwise or anticlockwise so that the corresponding movable compact shelf stably walks on the guide rail to open or close the compact shelf. However, in practical applications, driving the compact shelving through the operating handle also brings a plurality of troubles and inconveniences.
First, when a large number of stored objects are generally stored in the compact shelving, the compact shelving has a large load. At this time, the user needs to use a relatively large force to drive the operating handle so as to control the movement of the compact shelving. This is a great nuisance for women or children who are themselves less powerful, who have to resort to or use the compact shelf smoothly with the assistance of others. In other words, since the operating handle is required to be manually operated, when the load of the compact shelving exceeds a certain level, the driving of the operating handle itself becomes a great trouble.
Of course, a relatively straightforward way to solve the above problems is to increase the length of the operating handle. However, in the application scenario of the compact shelving, the technical scheme of increasing the length of the operating handle is often difficult to implement, because when the size of the operating handle is excessively increased, the operating handle not only occupies extra space and affects the beauty, but also can obstruct the walking of a user due to the larger size, and the user can easily touch the operating handle by mistake when walking beside the compact shelving.
That is, for the operation handle, on the one hand, it is required to be small in size so as not to occupy a space and to affect the beauty, and on the other hand, it is required to be large in size so as to be manually actuated by the user. Therefore, a new driving handle is designed to solve the above-mentioned contradictory requirements.

schematic compact shelf
As shown in fig. 1-4, the compact shelf according to the preferred embodiment of the present application is illustrated, wherein the compact shelf is suitable for storing stored objects such as archives, securities certificates, and the like, and has the advantages of secure enclosure, high space utilization, convenient access, and the like. In the embodiment of the present application, the type of the compact shelf is not limited by the present application. For example, if divided by operation, the compact shelf includes, but is not limited to, a manual compact shelf, an electric compact shelf, and an electronic intelligent compact shelf; if the shelves are classified according to different purposes, the shelves include, but are not limited to, archives shelves, books shelves, accountant shelves, cases shelves and the like; if the shelves are classified according to different structures, the shelves include, but are not limited to, open shelves, semi-closed shelves and fully-closed shelves.
As shown in fig. 1, the compact shelving according to the embodiment of the application includes a plurality of compact shelving bodies 10, a guide rail 20 and a transmission device 30, wherein the compact shelving bodies 10 are installed on the guide rail 20 in a column-by-column manner, and the compact shelving bodies 10 are mutually movable under the driving control of the transmission device 30 so as to be switched between a storage position and an open position. When the movable rack is positioned in the storage position, the movable rack bodies 10 are mutually sealed to form a sealed storage environment; when the movable rack 10 is switched to the open position, the movable rack 10 can travel on the guide rail 20 in a single row or multiple rows together to open the corresponding movable rack 10.
Specifically, as shown in fig. 1, each of the compact shelving bodies 10 includes a chassis 11, a plurality of columns 12, a plurality of side plates 13, a plurality of shelves 14, a top plate 15, and other necessary elements (not shown), wherein the chassis 11 is mounted to a guide rail 20, the plurality of columns 12 and the plurality of side plates 13 are respectively mounted to the chassis 11 and spaced apart from each other, and the plurality of shelves 14 are mounted between two adjacent columns 12 or between two adjacent columns 12 and side plates 13, so as to define a plurality of storage spaces 100 for storing objects to be stored by the shelves 14 and the columns 12 or the shelves 14, the columns 12 and the side plates 13. Accordingly, in the embodiment of the present application, the compact shelving 10 further includes door panels 17 disposed on the compact shelving located at two edge rows, so as to seal the storage space 100.
As shown in fig. 1, the transmission device 30 includes an operating handle 40, a transmission mechanism (not shown) and a shaft wheel 50, wherein the operating handle 40 is mounted on the side plate 13 of the compact shelving body 10, the shaft wheel 50 is mounted on the chassis 11 of the compact shelving body 10 and is rollably supported on the guide rail 20, and the transmission mechanism is disposed between the operating handle 40 and the shaft wheel 50, and is used for transmitting the acting force applied to the operating handle 40 to the shaft wheel 50, so as to drive the shaft wheel 50 to slide along the guide rail 20, thereby driving the compact shelving body 10 to switch between the storage position and the open position. During operation, the operating handle 40 may be rotated in a clockwise or counterclockwise direction, so that the rotation of the operating handle 40 is converted into the rotation of the shaft wheel 50 in a clockwise or counterclockwise direction through the transmission mechanism, so that the corresponding compact shelf 10 stably travels on the guide rail 20. In a specific implementation, the transmission mechanism includes necessary elements such as a connecting shaft, a sprocket, a bearing, a chain, a connecting pipe, etc., and as the transmission mechanism belongs to the prior art, the transmission mechanism is not described herein.
As previously mentioned, the operating handle is required to be small in size so as not to occupy space and to affect the aesthetic appearance on the one hand, and large in size so as to be manually actuated by the user on the other hand. In this application, the operating handle has a special structural configuration to have two seemingly contradictory technical advantages of smaller size and convenient driving.
Specifically, fig. 2 illustrates a perspective view of an operating handle of the compact shelf according to the preferred embodiment of the present application. Fig. 3 illustrates a cross-sectional view of the operating handle of the compact shelf according to the preferred embodiment of the present application. As shown in fig. 2 and 3, the operating handle 40 includes a rotation shaft 41 connected to a transmission mechanism and an operating tube handle 42 extending outwardly from the rotation shaft 41 and operatively connected to the rotation shaft 41, wherein when the operating tube handle 42 is driven to rotate clockwise or counterclockwise about the rotation shaft 41, the rotation shaft 41 is driven and transmitted to the shaft wheel 50 by the transmission mechanism to drive the compact shelf 10 to move along the guide rail 20.
In particular, as shown in fig. 2 and 3, in the embodiment of the present application, the operating handle 42 includes a hollow handle body 421 having a receiving groove 4212 and an extension handle 422, wherein the extension handle 422 is telescopically coupled within the receiving groove 4212 of the hollow handle body 421, such that the operating handle 42 has different lengths in different use states. For ease of illustration, the state of the operating handle 42 is defined herein as a storage bit and an operating bit.
Fig. 4 illustrates a length adjustment process of the operating handle of the compact shelf according to the preferred embodiment of the present application. As shown in fig. 4, when switched to the operating position, the extension stem 422 can extend outwardly along the receiving slot 4212 to extend the length of the operating stem 42. It should be appreciated that when the extension stem 422 extends outwardly along the receiving groove 4212, the arm of force of the operating stem 42 with respect to the rotation shaft 41 is extended. Mathematically, the moment is equal to the force multiplied by the arm, so that when the length of the arm is increased, the required rotational force is reduced, producing the same moment. That is, the user rotates the operating handle 40 with a smaller rotation force after switching to the operating position, as compared with the conventional operating handle, to improve the convenience of operation of the operating handle 40.
It should be noted that, as shown in fig. 2, the operating handle 42 extends downward from the rotating shaft 41 at a right angle, in other words, in this embodiment, the length of the arm is the length of the operating handle 42. Accordingly, after being switched to the operating position, the length of the extension stem 422 is increased relative to the central control stem 421, so that the overall length of the operating stem 42 is increased, thereby requiring relatively less driving force on the premise of achieving the same driving torque. Thus, even a female or a child having relatively little strength can independently complete the driving of the operating handle 40.
After the operation is completed, the extension stem 422 may be retracted inwardly along the receiving groove 4212 to reduce the overall length of the operation stem 42 to switch the operation stem 42 back to the storage position. That is, when being switched to the storage position, the extension pipe handle 422 is retracted inward along the receiving groove 4212 to reduce the length of the operation pipe handle 42, so as to reduce the space occupation of the operation pipe handle 42. That is, in the embodiment of the present application, the operating handle 40 can have both the technical advantages of small size and convenient driving, which are seemingly contradictory.
More specifically, as shown in fig. 2-4, in the embodiment of the present application, the extension stem 422 is telescopically coupled within the receiving groove 4212 of the central control stem 421 by a connection spring 423, wherein, when in the storage position, the connection spring 423 disposed between the hollow stem 421 and the extension stem 422 is compressed to minimize the overall length of the operating stem 42; when switched to the operating position, the compressed connecting spring 423 is released to drive the extension pipe handle 422 outwardly along the receiving groove 4212 to increase the overall length of the operating pipe handle 42. As shown in fig. 2-4, one end of the compression spring 423 is fixedly connected to the bottom of the accommodating groove 4212, and the opposite end is connected to the end of the extension pipe handle 422, so as to drive the extension pipe handle 422 to switch between the storage position and the operation position, wherein when the compact shelf 10 does not need to be moved, the operation pipe handle 42 is in a compressed state, so as to reduce the space occupation rate of the operation pipe handle 42; when the compact shelving body 10 needs to be operated, the operating pipe handle 42 is in an extended state so as to increase the moment arm for convenient driving.
It should be noted that, when the compact shelving body 10 does not need to be moved, the length of the arm of force of the operating tube handle 42 relative to the rotating shaft 41 is the shortest, that is, the force required for rotating the handle 40 becomes large, so that the operating handle 40 cannot be easily rotated by an external force, so as to prevent some force generated by accidental touch and other reasons from causing the operating handle 40 to rotate, thereby accidentally driving the compact shelving body 10, reducing the occurrence of accidents and improving the use safety of the compact shelving.
Further, in this embodiment, as shown in fig. 2 to 4, the operating handle 42 further includes a reset button 424, where the reset button 424 is installed in the first installation hole 4211 of the hollow handle body 421, the extension handle 422 includes a clamping member 4221 and a reset spring 4222, and has a second installation hole 4223, and the clamping member 4221 is movably installed in the second installation hole 4223 up and down through the reset spring 4222, so that the state switching control of the operating handle 42 is implemented through the first installation hole 4211, the clamping member 4221, the reset spring 4222, and the second installation hole 4223.
Specifically, when the operating handle 42 is in the storage position, the locking member 4221 is locked in the first mounting hole 4211 of the hollow handle body 421, and the locking member 4221 is aligned with the return spring 4222, so that the connecting spring 423 disposed between the hollow handle body 421 and the extension handle 422 is compressed to reduce the overall length of the operating handle 42.
When the operating lever 42 is required to be switched to the operating position, the reset button 424 is pressed, and the locking member 4221 is driven by the reset spring 4222 to move downward so as to be disengaged from the first mounting hole 4211. At this time, the connecting spring 423 is in a compressed state and tends to return to a natural state of motion. Therefore, when the locking member 4221 is disengaged from the first mounting hole 4211, the connection spring 423 is released to drive the extension stem 422 to extend outwards along the receiving groove of the hollow stem 421, so as to extend the length of the operation stem 42.
After the operation is completed, the manipulation handle 42 is changed back to the storage position, that is: pressing the extension pipe handle 422 inward to compress the connection spring 423, and the return spring 4222 is in a compressed state; further, when the extension stem 422 is pressed to align the locking member 4221 with the first mounting hole 4211, the locking member 4221 is driven to move upwards under the elastic force of the return spring, so that the locking member 4221 is locked in the first mounting hole 4211 to fix the extension stem 422 in the central control stem 421.
In summary, in the embodiment of the present application, the user can realize switching of the state of the operation lever 42 with only a simple operation to lengthen or retract the operation lever 42. Specifically, in the embodiment of the present application, the operation of the operation handle 42 is switched to the operation position by pressing the reset button 424 to extend the operation handle 42, and the operation of the operation handle 42 is switched to the storage position by pressing the rolled long handle 422 to retract the operation handle 42, in such a manner that the user can save more effort when the operation handle 42 is used, and the operation handle is smaller in size and occupies less space when not used.
For convenience of operation, as shown in fig. 2-4, in the embodiment of the present application, the operating handle 40 further includes a grip 43 extending transversely from the head of the extension handle 42, so that the user can grip the grip 43 to rotate the handle 40 continuously, without changing a gesture every time it rotates an angle, thereby improving the user experience. In particular, in the embodiment of the present application, the grip 43 is parallel to the rotation shaft 41, so as to be convenient for a user to grip. More preferably, the grip handle 43 is further externally sleeved with a slip-preventing sleeve 44 made of a flexible material to increase friction between the user and the grip handle 40, facilitate rotation, and protect the palm of the user from damage when rotating the handle 40.
Fig. 5 illustrates a schematic view of a modified implementation of the operating handle of the compact shelf according to the preferred embodiment of the present application. As shown in fig. 5, in this modified embodiment, the operating handle 40A includes three operating handles 42 extending radially outward from the rotating shaft 41, wherein each two adjacent operating handles 42 are 120 degrees therebetween, in such a manner that when the user operates the operating handle 40A, he can hold any two operating handles 42 with both hands and rotate them, so that the rotation is easier and more convenient, and the control is more precise. Preferably, an anti-slip sleeve 44 is sleeved on each of the operating handles 42 to increase friction between a user and the handle 40A for easy rotation, while protecting the palm of the user from damage during rotation of the handle 40A. It should be noted that in this modified embodiment, the operating handle 40A includes three operating handles 42 is merely an example, and in other examples, the operating handle 40A may include a greater number or a smaller number of operating handles 42, which is not limited in this application.
Fig. 6 illustrates a schematic view of another variant implementation of the operating handle of the compact shelf according to the preferred embodiment of the present application. As shown in fig. 6, the operating handle 40B further includes an annular handle 51 mounted on the three operating handles 42, as compared to the modified embodiment illustrated in fig. 5, to strengthen the operating handles 42 and prevent the operating handles 42 from being broken by excessive force during the rotation. Meanwhile, the annular rotating wheel 51 is convenient for a user to hold, so that the operation is more convenient. Similarly, the annular tube handle 51 is externally sleeved with an anti-slip sleeve 44 to increase friction between the user and the annular tube handle 51 for convenient rotation while protecting the palm of the user from damage when the operating handle 40B is rotated.
