Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and more specifically to a drawer-type electric control box. Background Art

[0002] In the field of industrial control and electrical equipment installation, the electric control box is a critical component. It is responsible for important functions such as control, protection and power distribution of various electrical equipment. With the continuous improvement of industrial automation, higher requirements are put forward for the installation convenience, stability and reliability of the electric control box.

[0003] Traditional installation methods of electric control boxes are often relatively simple and direct, such as bolt fixing or simple snap-on connection. When faced with some application scenarios that require frequent pulling and pulling operations to facilitate inspection, maintenance or replacement of internal electrical components, the existing technical solutions expose obvious defects. Taking the common pull-out electric control box with simple snap-on connection as an example, when fixing the electric control box body, it only relies on a single direction or a small number of snap-on structures for positioning. In actual use, this fixing method is difficult to achieve accurate positioning of the electric control box body in the box body, and it is easy to cause displacement deviation of the electric control box body in the chassis groove. Especially in industrial environments, it is often disturbed by external forces such as vibration and impact. The simple snap-on structure cannot provide sufficient restraint to resist these external forces, causing the electric control box body to easily shake or even loosen in the front and back or left and right directions. Once the electric control box body is loose, it will not only affect the stability of the electrical connection, causing problems such as poor contact and signal transmission interruption, but also may cause electrical faults in severe cases, such as short circuit and open circuit, which will pose a great threat to the safe and stable operation of the entire electrical system, increase the time and cost of equipment downtime and maintenance, and reduce production efficiency.

[0004] Therefore, a pull-out type electric control box is proposed. Utility Model Content

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A pull-out electric control box comprises a box body, wherein the front end of the box body is provided with a plurality of sets of box grooves at equal intervals in the vertical direction, and an electric control box body is installed in each box groove in a pull-out manner in the front-back direction, and longitudinal cavities are symmetrically provided on both sides of the interior of each electric control box body, and the longitudinal cavities penetrate the front and back ends of the electric control box body, and a self-rotating limit rod assembly is rotatably installed in each longitudinal cavity;

Rotating the limit rod assembly can flip the block through the docking interface and clip it into the corresponding lateral positioning slot 2, thereby realizing the positioning and fixation of the electric control box body in the chassis groove, and in the fixed state, the rear side of the electric control box body and the inner bottom surface of the chassis groove are electrically connected through the terminal docking assembly.

[0009] Preferably, the limit rod assembly includes a limit rod body located inside the longitudinal cavity, a clamping block is radially welded on the rod body of the corresponding limit rod body, a knob is provided at the front end of the electric control box body, a rear end of the knob is fixedly connected to the front end of the limit rod body extending forward from the longitudinal cavity, the rear end of the limit rod body extends backward from the longitudinal cavity, a bearing is provided inside each longitudinal cavity, the outer side of the bearing is fixed to the inner wall surface of the longitudinal cavity through a protrusion, and the limit rod body passes through the inner ring of the bearing;

[0010] The limit rod body is in an L-shaped structure with its short axis end facing the rear side. The limit rod body cooperates with the bearing component through its long axis end to achieve rotational support, and rotating the knob component can drive the limit rod body to rotate clockwise or counterclockwise around its axis in the bearing component, thereby realizing the engagement and disengagement operation between the block and the lateral positioning slot 2 and the rear end of the limit rod body and the limit rod slot 1.

[0011] Preferably, each of the limit rod slots is an L-shaped groove, and its shape and size are compatible with the L-shaped short axis end of the limit rod body.

[0023] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0024] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0025] A pull-out electric control box includes a box body 1, an electric control box body 2, a limit rod assembly, a bearing member 4, a terminal docking assembly, a control panel 201, a handle 202 and other components. The specific implementation method is described in detail below.

[0026] The box body 1 is the outer shell structure of the entire pull-out electric control box, and its front end is vertically and evenly spaced with multiple sets of box grooves 101. Each set of box grooves 101 provides an installation space for the electric control box body 2, so that the electric control box body 2 can be pulled out and installed therein along the front and rear direction.

[0027] The electric control box body 2 is the core control unit, and longitudinal cavities 204 are symmetrically opened on both sides thereof. The longitudinal cavity 204 runs through the front and rear ends of the electric control box body 2, and a limit rod assembly for positioning and fixing is installed in the longitudinal cavity 204. The limit rod assembly includes a limit rod body 301 and a clamping block 302. The clamping block 302 is radially welded on the rod body of the limit rod body 301 and is located in the longitudinal cavity 204. The front end of the limit rod body 301 extends forward from the longitudinal cavity 204 and is fixedly connected to the rear end of the knob member 3 installed on the front end surface of the electric control box body 2. The rear end extends backward from the longitudinal cavity 204 and is in an L-shaped structure, with its short axis end facing the rear side.

[0028] Two limit rod clamping grooves 102 are symmetrically provided on the inner bottom surface of the chassis groove 101 in the transverse direction, and their shapes and sizes are precisely matched with the L-shaped short axis end of the limit rod body 301. When the electric control box body 2 is pushed into the chassis groove 101, the rear end of the limit rod body 301 is inserted into the limit rod clamping groove 102, and the limit rod body 301 is driven to rotate clockwise or counterclockwise around its axis in the bearing member 4 by rotating the knob member 3, so that the L-shaped short axis end of the limit rod body 301 rotates in the limit rod clamping groove 102 to achieve stable clamping. A bearing member 4 is installed in each longitudinal cavity 204, and the outer periphery of the bearing member 4 is fixed to the inner wall of the longitudinal cavity 204 through a protrusion, and the limit rod body 301 passes through the inner ring of the bearing member 4. The bearing member 4 here can be a deep groove ball bearing or a cylindrical roller bearing, which provides low-friction rotation support for the limit rod body 301, ensures the smoothness and stability of rotation, and can withstand certain radial and axial loads, adapting to the force exerted on the limit rod assembly by the electric control box body 2 during the pulling and fixing process.

[0029] The inner walls on both sides of the chassis groove 101 are provided with lateral positioning card grooves 103 along the length direction thereof, and the two sides of the electric control box body 2 are provided with docking ports 205 corresponding to the horizontal lateral positioning card grooves 103, and the docking ports 205 are connected with the corresponding longitudinal cavity 204. When the limit rod body 301 is rotated, the card block 302 is turned over through the docking port 205 and is inserted into the corresponding lateral positioning card groove 103, thereby realizing the lateral positioning and fixing of the electric control box body 2 in the chassis groove 101, and preventing the electric control box body 2 from being displaced in the left and right directions in the chassis groove 101. In this fixed state, the rear side of the electric control box body 2 and the inner bottom surface of the chassis groove 101 are electrically connected through the terminal docking assembly. The terminal docking assembly includes a docking connector 203 opened on the rear side of the electric control box body 2 and a power plug 104 installed on the bottom surface of the chassis groove 101. The docking connector 203 and the power plug 104 are compatible plug-in connection structures. The connection method complies with relevant electrical connection standards, has good conductivity and stability, and can achieve reliable electrical connection after the electric control box body 2 is pulled into place and fixed, and can still maintain a low contact resistance during multiple plug-in and pull-out processes to ensure efficient and safe power transmission.

[0030] A control panel 201 is installed at the front end of each electric control box body 2. The control panel 201 is used to control and monitor the electrical equipment in the electric control box body 2. A plurality of control buttons, indicator lights, display screens and other components are arranged on its surface to intuitively display the working status of the electric control box body 2 and adjust its internal electrical parameters. The operator can conveniently operate and control the electric control box body 2 through the control panel 201 to meet different control requirements. The control panel 201 is a prior art and will not be described in detail here.

[0031] A pair of handles 202 are symmetrically mounted on the lower front side of the electric control box body 2. The handles 202 are ergonomically designed and have anti-slip patterns on their surfaces. When the electric control box body 2 needs to be pulled out, the operator can conveniently hold the handles 202 and apply appropriate force to smoothly pull out and move the electric control box body 2 in the chassis groove 101, thereby improving the convenience and comfort of operation.

[0032] In summary, the pull-out electric control box of the utility model realizes stable pulling, precise positioning and reliable electrical connection of the electric control box body 2 in the box body 1 through the ingenious design and coordinated cooperation between the various components. Its structural design is reasonable, easy to operate, can meet the needs of various industrial control and electrical equipment installation scenarios, effectively improves the performance and reliability of the electric control box, reduces the installation and maintenance costs, and has broad application prospects.

[0033] The working principle and use process of this utility model:

[0034] 1. Installation process

[0035] First, align the electric control box body 2 with the chassis groove 101 at the front end of the box body 1 , and slowly push the electric control box body 2 in along the direction of the chassis groove 101 by holding the handle 202 .

[0036] When the electric control box body 2 is completely pushed into the chassis groove 101 , the rear end of the limit rod body 301 is just located above the limit rod slot 1 102 , and the block 302 is in corresponding positions with the docking port 205 and the lateral positioning slot 2 103 .

[0037] Next, the knob 3 at the front end of the electric control box body 2 is rotated, and the knob 3 drives the limit rod body 301 to start rotating under the support of the bearing member 4. The rear end of the limit rod body 301 is gradually inserted into the limit rod slot 1 102 during the rotation process, and the block 302 is turned outward through the docking interface 205 and inserted into the lateral positioning slot 2 103. In this process, due to the low friction characteristics of the bearing member 4, the rotation operation is relatively easy and smooth, and it can ensure that the limit rod body 301 and the block 302 are accurately inserted into the corresponding slots, so that the electric control box body 2 is stably fixed in the chassis groove 101.

[0038] While the electric control box body 2 is fixed, the docking joint 203 on its rear side realizes a tight plug-in connection with the power plug 104 on the inner bottom surface of the chassis groove 101, establishing a reliable electrical connection, thereby providing power supply for the electrical equipment in the electric control box body 2 and ensuring its normal operation.

[0039] 2. Usage process

[0040] After the electric control box body 2 is installed and powered on, the operator can control and monitor the electrical equipment in the electric control box body 2 through the control panel 201 at the front end of the box body 1. The control buttons on the control panel 201 can be used to start, stop or adjust the operating parameters of the equipment, the indicator lights can intuitively display the working status of the equipment, and the display screen can provide detailed electrical parameter information, which is convenient for the operator to timely understand and grasp the operating status of the equipment and make corresponding operational adjustments as needed.

[0041] 3. Disassembly process

[0042] When the electric control box body 2 needs to be inspected, maintained or replaced, the power supply needs to be cut off first to ensure safe operation.

[0043] Then, the knob 3 is rotated in the reverse direction to make the limiting rod body 301 rotate in the reverse direction in the bearing 4. At this time, the rear end of the limiting rod body 301 gradually escapes from the limiting rod slot 102, and the block 302 also rotates back into the longitudinal cavity 204 from the lateral positioning slot 2 103 through the docking port 205.

[0044] Finally, hold the handle 202 and pull out the electric control box body 2 along the chassis groove 101 to complete the disassembly operation, making it convenient to perform subsequent processing on the electric control box body 2.

[0045] Through the above-mentioned use process, the pull-out electric control box of the utility model can be conveniently installed, used and disassembled, and the cooperation between the various components is tight and efficient, which effectively improves the practicality and maintainability of the electric control box.

[0046] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
