Detailed implementation manners

[0053] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0054] Referring to Figure 1 as shown, a switchgear cabinet 1 that is convenient to pull out in this embodiment includes: a switchgear cabinet 1 body and a plurality of equipment drawers 20.

[0055] Among them, the switchgear cabinet 1 body includes a plurality of brackets 101; the equipment drawers 20 are slidably connected to the switchgear cabinet 1 body, and this sliding connection can be realized by using a general drawer slide rail. The specific structure of the drawer slide rail is a well-known technical solution to those of ordinary skill in the art and is not the focus of the improvement of the present utility model, so it will not be elaborated here.

[0056] Generally speaking, the equipment drawers 20 can be arranged on the front side of the switchgear cabinet 1 body. After the user opens the cabinet door (not shown) of the switchgear cabinet 1, the electrical components accommodated therein can be repaired by pulling out the equipment drawers 20.

[0057] Referring to Figures 1 to 9 as shown, specifically, the equipment drawer 20 includes: a drawer body 210, a drawer handle 220, and a floating connection assembly 230. Among them, the drawer body 210 forms a drawer space for accommodating electrical equipment; the drawer handle 220 is used for the user to hold to pull or push the drawer body 210.

[0058] The key improvement of the present utility model lies in the floating connection assembly 230. Specifically, the floating connection assembly 230 is respectively movably connected to the drawer body 210 and the drawer handle 220 so that the drawer handle 220 and the drawer body 210 are rotationally connected about the first rotation axis 230a and the second rotation axis 230b; wherein, the relative sliding direction of the equipment drawer 20 and the switch cabinet 1 is perpendicular to the plane where the first rotation axis 230a and the second rotation axis 230b are located.

[0059] In this way, when the user pulls the drawer handle 220, a floating connection effect will be generated, rather than directly acting on the drawer body 210. In this way, the drawer body 210 will only receive a relatively horizontal pulling force and a very small component of the acting force in other directions, so that the drawer slides on both sides of the drawer body 210 will not be bent or damaged due to impact, effectively improving the service life of the equipment drawer 20.

[0060] Refer to Figure 4 As shown, specifically, in some embodiments, the first rotation axis 230a is perpendicular to the second rotation axis 230b. This is equivalent to forming an orthogonal rotational connection pair, thereby providing multiple floating directions based on the orthogonal axes.

[0061] Refer to Figures 2 to 9 As shown, specifically, in some embodiments, the floating connection assembly 230 includes: a first connection block 231, a second connection block 232, an intermediate connection block 233, a first pin 234, a second pin 235, etc.

[0062] Among them, the first connection block 231 is fixedly connected to the drawer body 210; the intermediate connection block 233 is rotationally connected to the first connection block 231 about the first rotation axis 230a. Correspondingly, the second connection block 232 is fixedly connected to the drawer handle 220; wherein, the second connection block 232 is rotationally connected to the intermediate connection block 233 about the second rotation axis 230b. That is, the floating connection of the present utility model is realized through multiple sections of structures, making each part easy to manufacture and assemble.

[0063] Refer to Figures 2 to 5As shown, specifically, in some embodiments, the first connecting block 231 includes: a first fixing portion 2311 and a first rotating shaft portion 2312. Among them, the first fixing portion 2311 is at least partially embedded in the drawer body 210; the first rotating shaft portion 2312 is formed with a first connecting shaft hole 2314; the first rotating shaft portion 2312 is formed with two first types of avoidance inclined surfaces 2313 parallel to the first rotation axis 230a; the first type of avoidance inclined surfaces 2313 intersect the second rotation axis 230b obliquely. Specifically, in some embodiments, the intermediate connecting block 233 is formed with two second types of avoidance inclined surfaces 2333 parallel to the second rotation axis 230b; the second type of avoidance inclined surfaces 2333 intersect the second rotation axis 230b obliquely.

[0064] The first type of avoidance inclined surface 2313 and the second type of avoidance inclined surface 2333 are provided to provide a larger rotation space, so that when the user operates the drawer handle 220 within a large angular range, the floating connection assembly 230 can still play a corresponding protection effect.

[0065] Adopting the above solution, the first fixing portion 2311 is used to realize the connection with the drawer body 210; the second connecting block 232 and the drawer handle 220 form a fixed connection.

[0066] As a preferred solution, the first fixing portion 2311 has an external thread, and the drawer body 210 has a threaded hole, and they are tightly connected through a threaded structure.

[0067] As an alternative solution, the first fixing portion 2311 and the drawer body 210 can also achieve a certain floating connection, such as a bolt made of plastic material, and a certain connection clearance is brought by the plasticity of the plastic.

[0068] Referring to Figure 5 As shown, specifically, in some embodiments, the intermediate connecting block 233 is formed with a first intermediate shaft hole 2331, and the first intermediate shaft hole 2331 is aligned with the first connecting shaft hole 2314; a first shaft pin 234 is inserted into the first intermediate shaft hole 2331 and the first connecting shaft hole 2314. The second connecting block 232 is formed with a second connecting shaft hole 2321; the intermediate connecting block 233 is formed with a second intermediate shaft hole 2332 aligned with the second connecting shaft hole 2321; a second shaft pin 235 is inserted into the second intermediate shaft hole 2332 and the second connecting shaft hole 2321. In this way, a sufficient connection strength can be achieved through the cooperation of the shaft pin and the shaft hole.

[0069] Referring to Figure 4 and Figure 5As shown, specifically, in some embodiments, the device drawer 20 includes more than two sets of the floating connection components 230; the two sets of floating connection components 230 are arranged in alignment along the width direction of the drawer handle 220. This can take into account both the connection strength and the floating connection effect.

[0070] It should be noted that at this time, due to the limiting effect of the two sets of floating connection components 230 on each other, the shaft holes where the first pin 234 and the second pin 235 are located can no longer be cylindrical holes, but need to be constructed as waist-shaped holes to provide a larger floating clearance, so that the two sets of floating connection components 230 can produce a synergistic floating effect.

[0071] Refer to Figure 4 and Figure 5 As shown, the drawer handle 220 includes: a mounting portion 221 and a handle portion 222. Among them, the mounting portion 221 is used to form a connection with the floating connection component 230; the handle portion 222 is used for the user to hold; among them, the drawer handle 220 forms a handle through hole for the user's hand to pass through between the mounting portion 221 and the handle portion 222.

[0072] Refer to Figures 4 to 9 As shown, in some embodiments, the device drawer 20 further includes: an elastic member 240. Among them, the elastic member 240 is disposed between the drawer body 210 and the drawer handle 220 to apply a restoring elastic force to the drawer handle 220, that is Figure 6 the state shown, so that the drawer handle 220 can save space in the reset state (folded state), and at the same time avoid the drawer handle 220 having a definite state when not in use, thereby avoiding being damaged by foreign objects.

[0073] Specifically, the elastic member 240 can be constructed as a torsion spring, one end of the torsion spring abuts against the drawer handle 220 and the other end abuts against the drawer body 210. The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the embodiments of the present disclosure.
