Description

Technical Field

[0001] The utility model belongs to the technical field of casing, and particularly relates to a casing with a connection structure. Background Art

[0002] A casing is an insulating device for introducing a live conductor into an electrical equipment or passing through a wall. The former is called an electrical appliance casing, and the latter is called a wall-piercing casing. Casings are usually used in the basement of buildings and are iron rings used to protect pipes or facilitate pipe installation. The classifications of casings include rigid casings, flexible waterproof casings, steel pipe casings, and iron sheet casings, etc.

[0003] The existing publication number: CN209671826U discloses a flange casing connection structure, which includes a first flange casing and a second flange casing. The aforementioned first flange casing includes a first casing part and a first flange part connected to the first casing part. The aforementioned second flange casing includes a second casing part and a second flange part connected to the second casing part. Clamping blocks are provided on the outer peripheral edges of the first flange part and the second flange part. In the state where the aforementioned clamping blocks are provided on the first flange part and the second flange part, the aforementioned first clamping part is in close contact with the outer end face of the first flange part, and the aforementioned second clamping part is in close contact with the outer end face of the second flange part. The clamping blocks can directly transmit the impact force to the joints of the flange casings through the first clamping part and the second clamping part, effectively avoiding the direct force on the bolts of the flange casings and protecting the connection strength of the bolts.

[0004] However, there are some problems in the prior art: Traditional connection methods for iron sheet casings, such as welding, clamping or threaded connection, all fix the position of the iron sheet casing. However, for iron sheet casings used in basements, corrosion, rusting, etc. will occur in a humid environment for a long time. When the iron sheet casing is welded, if the welding effect is not good, it will also cause the entire iron sheet casing to be unusable, so that the damaged part cannot be replaced separately, resulting in waste of iron sheet casing materials. Therefore, we propose a casing with a connection structure. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a casing with a connection structure, which has the advantage of being able to quickly replace the damaged iron sheet casing separately, and solves the problems that for iron sheet casings used in basements, corrosion, rusting, etc. will occur in a humid environment for a long time. When the iron sheet casing is welded, if the welding effect is not good, it will also cause the entire iron sheet casing to be unusable, so that the damaged part cannot be replaced separately, resulting in waste of iron sheet casing materials.

[0006] The utility model is realized as follows. A casing with a connection structure includes:

[0007] The top pipe and the bottom pipe. A connecting pipe is provided at the left end of the top pipe. An installation pipe is fixedly installed on the right side of the connecting pipe. The surface of the installation pipe is an external thread, and the interiors of the top pipe and the bottom pipe are both internal threads. The installation pipe is threadedly installed with both the top pipe and the bottom pipe. Installation blocks are fixedly installed at both the top and the bottom of the top pipe. A placement groove is formed inside the installation block. Placement blocks are fixedly installed at both the top and the bottom of the bottom pipe. A triangular block is fixedly installed on the back of the placement block;

[0008] A limiting assembly, which is located inside the placement groove. The limiting assembly is used to press the triangular block to move backward, and make the top pipe and the bottom pipe move toward each other simultaneously.

[0009] The limiting assembly includes a roller. The roller is located inside the placement groove. The back of the triangular block extends into the placement groove, and the surface of the roller contacts the outside of the triangular block.

[0010] The limiting assembly includes a roller. The roller is located inside the placement groove. The back of the triangular block extends into the placement groove, and the surface of the roller contacts the outside of the triangular block.

[0011] Fixing blocks are fixedly installed on both sides of the top and the bottom of the top pipe. Stabilizing blocks are fixedly installed on both sides of the top and the bottom of the bottom pipe. A limiting rod is provided on the front side of the stabilizing block. The back of the limiting rod penetrates to the back of the fixing block, and a blocking block is fixedly installed on the back of the limiting rod.

[0012] A sliding groove is formed inside the fixing block, and a limiting groove is formed on the back of the fixing block. The blocking block is slidably installed in the sliding groove and inserted into the limiting groove.

[0013] A disc is fixedly installed at the front end of the limiting rod. A spring is sleeved on the surface of the limiting rod. The front end of the spring is fixedly installed with the back side of the disc, and the front end of the spring contacts the front side of the stabilizing block.

[0015] A handle is fixedly installed at the outer end of the screw rod, and anti-slip lines are formed on the surface of the handle.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. When the jacking pipe or the bottom pipe needs to be installed, the front side of the jacking pipe can be in contact with the back surface of the bottom pipe at this time. Then, the triangular block is pressed tightly by the limiting component. When the triangular block is stressed, it will move towards the back surface. The movement of the triangular block drives the placing block to move towards the back surface. The movement of the triangular block can move the jacking pipe and the bottom pipe towards the side close to each other at the same time, so that the jacking pipe and the bottom pipe can be installed. Then, the installation pipe is rotated to make it enter the inside of the jacking pipe and the bottom pipe, so that the jacking pipe, the bottom pipe and the installation pipe can be spliced.

[0018] 2. When the jacking pipe or the bottom pipe needs to be replaced, first rotate the connecting pipe. The rotation of the connecting pipe drives the installation pipe to disengage from the jacking pipe and the bottom pipe. Then, the limiting of the triangular block is released by the limiting component. Then, the jacking pipe and the bottom pipe can be pulled in opposite directions respectively to separate the jacking pipe and the bottom pipe. Finally, the damaged jacking pipe or bottom pipe can be replaced.

[0019] 3. Through the setting of the roller, when the roller is pushed inward, it will contact the outer side of the triangular block, so that the triangular block will gradually move towards the back surface. At this time, the jacking pipe and the bottom pipe can be pulled to move towards the side close to each other at the same time, so that the jacking pipe and the bottom pipe can be limited, and the sealing performance at the connection of the jacking pipe and the bottom pipe can also be increased.

Detailed implementation manners

[0029] To further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0030] As Figures 1 to 7 shown, a casing with a connection structure provided by an embodiment of the present utility model includes:

[0031] A jacking pipe 1 and a bottom pipe 2. A connecting pipe 3 is provided at the left end of the jacking pipe 1. An installation pipe 4 is fixedly installed on the right side of the connecting pipe 3. The surface of the installation pipe 4 is an external thread, and the interiors of both the jacking pipe 1 and the bottom pipe 2 are internal threads. The installation pipe 4 is threadedly installed with both the jacking pipe 1 and the bottom pipe 2. Installation blocks 5 are fixedly installed at both the top and bottom of the jacking pipe 1. A placement groove 6 is formed inside the installation block 5. Placement blocks 7 are fixedly installed at both the top and bottom of the bottom pipe 2. A triangular block 8 is fixedly installed on the back of the placement block 7;

[0032] A limiting component 9, which is located inside the placement groove 6. The limiting component 9 is used to press the triangular block 8 to move backward, and make the jacking pipe 1 and the bottom pipe 2 move towards each other simultaneously.

[0033] When the jacking pipe 1 or the bottom pipe 2 needs to be installed, at this time, the front side of the jacking pipe 1 can be contacted with the back of the bottom pipe 2. Then, the triangular block 8 is pressed by the limiting component 9. The triangular block 8 will move backward under the force. The movement of the triangular block 8 drives the placement block 7 to move backward. The movement of the triangular block 8 can move the jacking pipe 1 and the bottom pipe 2 towards each other simultaneously, so that the jacking pipe 1 and the bottom pipe 2 can be installed. Then, the installation pipe 4 is rotated to make it enter the interiors of the jacking pipe 1 and the bottom pipe 2, so that the jacking pipe 1, the bottom pipe 2 and the installation pipe 4 can be spliced;

[0034] When the jacking pipe 1 or the bottom pipe 2 needs to be replaced, first rotate the connecting pipe 3. The rotation of the connecting pipe 3 drives the installation pipe 4 to disengage from the jacking pipe 1 and the bottom pipe 2. Then, the limit on the triangular block 8 is released by the limiting component 9. Then, the jacking pipe 1 and the bottom pipe 2 can be pulled in opposite directions respectively to separate the jacking pipe 1 and the bottom pipe 2. Finally, the damaged jacking pipe 1 or bottom pipe 2 can be replaced.

[0035] The limiting component 9 includes a roller 91. The roller 91 is located inside the placement groove 6. The back surface of the triangular block 8 extends into the placement groove 6, and the surface of the roller 91 contacts the outer side of the triangular block 8.

[0036] Through the setting of the roller 91, when the roller 91 is pushed inward, it will contact the outer side of the triangular block 8, so that the triangular block 8 will gradually move backward. At this time, the top pipe 1 and the bottom pipe 2 can be pulled to move towards each other at the same time, so that the top pipe 1 and the bottom pipe 2 can be limited, and the sealing performance at the connection of the top pipe 1 and the bottom pipe 2 can also be improved.

[0037] Two connecting rods 92 are arranged inside each placement groove 6. A connecting plate 93 is arranged inside the placement groove 6. The inner side of the connecting plate 93 is fixedly installed with the outer ends of the connecting rods 92. The outer side of the connecting plate 93 is rotatably installed with a screw rod 94 through a bearing. The outer end of the screw rod 94 penetrates to the outside of the mounting block 5 and is threadedly installed with the mounting block 5. The surface of the roller 91 is fixedly installed with the inner ends of the connecting rods 92.

[0038] Through the mutual cooperation of the connecting rod 92, the connecting plate 93 and the screw rod 94, when the screw rod 94 is rotated, the connecting plate 93 can be driven to move inward. The inward movement of the connecting plate 93 drives the connecting rod 92 to move inward. The inward movement of the connecting rod 92 drives the roller 91 to move inward. The inward movement of the roller 91 can drive the triangular block 8 to move backward, so that the top pipe 1 and the bottom pipe 2 can be limited.

[0039] Fixing blocks 10 are fixedly installed on both sides of the top and bottom of the top pipe 1. Stabilizing blocks 11 are fixedly installed on both sides of the top and bottom of the bottom pipe 2. A limiting rod 12 is arranged on the front side of the stabilizing block 11. The back surface of the limiting rod 12 penetrates to the back surface of the fixing block 10, and a blocking block 13 is fixedly installed on the back surface of the limiting rod 12.

[0040] Through the mutual cooperation of the fixing block 10, the stabilizing block 11, the limiting rod 12 and the blocking block 13, when the limiting rod 12 is pushed backward, the blocking block 13 can be driven to move backward. When the blocking block 13 passes through the fixing block 10, the limiting rod 12 can be rotated at this time. The rotation of the limiting rod 12 drives the blocking block 13 to rotate 90 degrees, so that the blocking block 13 is in a vertical state, and at this time, the fixing block 10 and the stabilizing block 11 can be limited.

[0041] A sliding groove 14 is opened inside the fixing block 10, and a limiting groove 15 is opened on the back surface of the fixing block 10. The blocking block 13 is slidably installed in the sliding groove 14, and the blocking block 13 is inserted into the limiting groove 15.

[0042] Through the mutual cooperation of the sliding groove 14 and the limiting groove 15, the stopper 13 can slide inside the sliding groove 14. When the back surface of the stopper 13 passes through the back surface of the fixed block 10, the stopper 13 can be rotated by 90 degrees at this time so that it can enter the limiting groove 15, thereby limiting the fixed block 10 and the stabilizing block 11.

[0043] A disc 16 is fixedly installed at the front end of the limiting rod 12. A spring 17 is sleeved on the surface of the limiting rod 12. The front end of the spring 17 is fixedly installed with the rear side of the disc 16, and the front end of the spring 17 contacts the front side of the stabilizing block 11.

[0044] Through the mutual cooperation of the disc 16 and the spring 17, the baffle and the disc 16 can always bear the elastic force of the spring 17, so that the stopper 13 will be more stable when entering the limiting groove 15.

[0045] Sealing grooves 18 are provided at the top and bottom of the front side of the jacking pipe 1. A sealing strip 19 is fixedly installed on the back surface of the bottom pipe 2, and the sealing strip 19 is inserted into the sealing groove 18.

[0046] Through the mutual cooperation of the sealing groove 18 and the sealing strip 19, the sealing performance during the installation of the jacking pipe 1 and the bottom pipe 2 can be increased, preventing water leakage at the connection between the jacking pipe 1 and the bottom pipe 2.

[0047] A handle 20 is fixedly installed at the outer end of the screw rod 94, and anti-slip lines are provided on the surface of the handle 20.

[0048] Through the setting of the handle 20, the contact area when rotating the screw rod 94 can be increased, thereby improving the working efficiency when rotating the screw rod 94.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
