[0036] Please refer to Figure 1-Figure 3 The sleeve fixing structure 100 and the switch cabinet 1000 provided in the embodiment of the utility model can solve the above-mentioned problem, which will be described in detail below.
[0037] refer to Figure 1 and Figure 2An embodiment of the utility model provides a switch cabinet 1000, which includes a cabinet body 200, a support 300, a shield 400 and a sleeve fixing structure 100; wherein the sleeve 120 and the support 300 are both installed on the cabinet body 200, the first clamp 111 and the second clamp 112 are both connected to the support 300, and the shield 400 is connected to the support 300 and covers the first clamp 111, the second clamp 112 and the locking member 113.
[0038] The switch cabinet 1000 can shield and protect the clamping assembly 110 and the protrusion 122 by providing the protective cover 400, and can prevent foreign impurities from easily mixing into the clamping cavity 115 during operation, thereby negatively affecting the fixing or grounding performance of the protrusion 122.
[0039] refer to Figure 3 The support 300 includes a first base body 310 and a second base body 320 that are rotatably connected. The first base body 310 is installed on the cabinet 200 , and the first clamp 111 , the second clamp 112 and the shield 400 are all connected to the second base body 320 .
[0040] In the above technical solution, by making the first seat body 310 and the second seat body 320 rotatably connected, when there is no need to fix the protrusion 122, the second seat body 320 can drive the first clamp 111 and the second clamp 112 away from the protrusion 122, so as to facilitate the protrusion 122 or the clamping assembly 110 to be separately repaired or replaced; when the protrusion 122 needs to be fixed, the second seat body 320 is rotated relative to the first seat body 310, driving the first clamp 111 and the second clamp 112 to approach the protrusion 122 and clamp the protrusion 122, which helps to improve the ease of use of the entire switch cabinet 1000.
[0041] In this embodiment, in order to facilitate the rotation of the second base body 320 and the first base body 310, a handle 500 can be provided on the outside of the shield 400, so that the staff can apply force to drive the second base body 320 and the first base body 310 to rotate relative to each other. At the same time, in order to improve the storage performance of the switch cabinet 1000, a storage box 600 can also be provided on the outside of the shield 400, and the toilet paper box is located on the upper side of the handle 500 to avoid interference with the handle 500.
[0042] refer to Figure 1-Figure 3The sleeve fixing structure 100 is used for a switch cabinet 1000, and the sleeve fixing structure 100 includes a clamping assembly 110 and at least two sleeves 120; wherein the clamping assembly 110 includes a first clamp 111, a second clamp 112 and a locking member 113, the first clamp 111 and the second clamp 112 are spaced apart and form a clamping cavity 115, each sleeve 120 is accommodated in the clamping cavity 115 and contacts the first clamp 111 and the second clamp 112, and the locking member 113 is used to connect the first clamp 111 and the second clamp 112.
[0043] During the assembly process, the first clamp 111 and the second clamp 112 can clamp and fix each sleeve 120 at the same time, and the first clamp 111 and the second clamp 112 can contact each sleeve 120, avoiding the situation where individual sleeves 120 are not fixed or contacted properly, thereby reducing safety hazards.
[0044] refer to Figure 3 The sleeve 120 includes a barrel 121 and a convex head 122, the convex head 122 is connected to one end of the barrel 121, the convex head 122 is accommodated in the clamping cavity 115 and contacts the first clamp 111 and the second clamp 112, and the barrel 121 is located outside the clamping cavity 115. Specifically, the cross-sectional size of the convex head 122 is smaller than the cross-sectional size of the barrel 121, and the end surface of the barrel 121 contacts the side surfaces of the first clamp 111 and the second clamp 112.
[0045] In the above technical solution, the first clamp 111 and the second clamp 112 can only clamp the protrusion 122, which can reduce the setting distance between the first clamp 111 and the second clamp 112, thereby reducing the space of the clamping cavity 115 and reducing the arrangement length of the locking member 113, which helps to improve space utilization and save material costs.
[0046] In this embodiment, there are three sleeves 120, and the three sleeves 120 are arranged at equal intervals, that is, the three sleeves 120 are arranged in sequence along the same extension direction. In addition, locking pieces 113 are arranged on both sides of each sleeve 120, and the locking pieces 113 are arranged at equal intervals, that is, there are four locking pieces 113, and the four locking pieces 113 are arranged in sequence along the arrangement direction of the sleeves 120. By arranging the sleeves 120 and the locking pieces 113 at equal intervals, it can be ensured that the clamping force on the protrusion 122 on each sleeve 120 is relatively uniform, and the force on each locking piece 113 can also be uniform, thereby preventing the first clamp 111 and the second clamp 112 from being easily damaged, which helps to extend the service life of the clamping assembly 110.
[0047] It is worth noting that the sleeve 120 further includes a fixing plate 123 , and the cylinders 121 are disposed through the fixing plate 123 . The fixing plate 123 can improve the relative position stability between the plurality of cylinders 121 .
[0048] refer to Figure 3 The first clamp 111 includes a first guide plate 1111 and a first clamp 1112. The first guide plate 1111 is close to the second clamp 112 relative to the first clamp 1112, the first guide plate 1111 is in contact with the sleeve 120, and at least one of the first guide plate 1111 and the first clamp 1112 is connected to the locking piece 113; the second clamp 112 includes a second guide plate 1121 and a second clamp 1122. The second guide plate 1121 is close to the first clamp 111 relative to the second clamp 1122, the second guide plate 1121 is in contact with the sleeve 120, and at least one of the second guide plate 1121 and the second clamp 1122 is connected to the locking piece 113.
[0049] Specifically, each protrusion 122 will contact the first guide plate 1111 and the second guide plate 1121. The first guide plate 1111 and the second guide plate 1121 are both made of conductive materials, thereby facilitating grounding when arranging the grounding switch.
[0050] refer to Figure 3 The locking member 113 includes a first disc spring 1131, a second disc spring 1132 and a locking rod 1133. The first disc spring 1131 and the second disc spring 1132 are respectively located on the side where the first clamp 111 and the second clamp 112 are away from each other. The locking rod 1133 penetrates the first clamp 111 and the second clamp 112 at the same time. The first disc spring 1131 and the second disc spring 1132 are sleeved on the locking rod 1133.
[0051] Specifically, the first guide plate 1111, the first clamping plate 1112, the second guide plate 1121, and the second clamping plate 1122 are all provided with through holes, and the locking rod 1133 is used to penetrate the through holes to achieve connection and locking of multiple plates.
[0052] It is worth noting that the locking rod 1133 is used to lock and limit the first clamp 111 and the second clamp 112, and the first disc spring 1131 and the second disc spring 1132 are respectively used to apply clamping force to the first clamp 111 and the second clamp 112, so that the clamping force can be transmitted to the protrusion 122, thereby ensuring the clamping degree while meeting the design pressure value of the protrusion 122.
[0053] In addition, the locking member 113 further includes a locking sleeve 1134, which is accommodated in the clamping cavity 115 and sleeved on the locking rod 1133. In addition, the two ends of the locking sleeve 1134 are respectively abutted against the first clamping member 111 and the second clamping member 112. The locking sleeve 1134 can guide and limit the locking rod 1133 on one hand, and abut between the first clamping member 111 and the second clamping member 112 on the other hand to avoid excessive clamping of the protruding head 122.
[0054] It is worth noting that the locking rod 1133 can be a bolt, and the locking sleeve 1134, the first clamp 111 and the second clamp 112 can be provided with screw holes that match the bolt, and the self-locking performance of the threaded connection is used to further improve the locking stability.
[0055] In this embodiment, in order to prevent the first disc spring 1131 and the second disc spring 1132 from easily detaching, pressure heads can be formed at both ends of the locking rod 1133 respectively, and the pressure heads are used to press the first disc spring 1131 and / or the second disc spring 1132.
[0056] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
