Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and more specifically, to a shock-absorbing structure for a power distribution cabinet contactor that is easy to install. Background Technology

[0002] A contactor in a distribution cabinet is a switching device used for remote control circuits. They are typically used to control the starting and stopping of motors, heating equipment, and other high-current loads. A contactor consists of an electromagnet (coil), a set of contacts (main contacts and auxiliary contacts), and a mechanical mechanism.

[0003] A vibration damping structure for a power distribution cabinet contactor is disclosed in Chinese utility model patent announcement number CN203481667U. The structure includes a cabinet and a contactor mounted on the cabinet. Several rubber damping blocks are provided between the cabinet and the contactor housing. Compared with the prior art, this utility model adds rubber damping blocks between the cabinet and the contactor housing. When the contactor is working, most of the mechanical vibration is absorbed by the rubber damping blocks, thereby reducing vibration and preventing it from affecting other parts of the power distribution cabinet door, thus ensuring the safety and reliability of the entire power distribution cabinet.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When installing the contactor in the distribution cabinet contactor shock absorption structure, the contactor is installed using bolts and nuts, which is not efficient enough.

[0005] To address this issue, those skilled in the art have proposed a shock-absorbing structure for the contactor of a distribution cabinet that is easy to install. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a shock-absorbing structure for contactors in distribution cabinets that is easy to install; in order to solve the problem that the existing shock-absorbing structure for contactors in distribution cabinets uses bolts and nuts for installation, which results in low installation efficiency.

[0007] The solution adopted by this utility model to solve the technical problem is:

[0008] A shock-absorbing structure for a power distribution cabinet contactor that is easy to install includes a cabinet, several sets of mounting blocks installed inside the cabinet and evenly distributed, a slider that slides in cooperation with the mounting blocks and is used to install the contactor, and a locking member for fixing the slider and the mounting blocks; a sliding groove is provided on the slider that slides in cooperation with the slider, and the slider is located in the sliding groove and slides in cooperation with the sliding groove; a buffer pad is provided on the side of the mounting block near the contactor.

[0009] In some possible implementations, the slider is provided with a mounting assembly for removably mounting the contactor.

[0010] In some possible implementations, the mounting assembly includes a slot disposed on the slider and fitted with a contactor, a plug inserted into the slot and connected to the contactor, and a limiting device slidably mounted on the slider with one end extending into the slot and engaging with the plug.

[0011] The limiting device consists of two sets, which are arranged opposite to each other along the insertion direction of the insert block.

[0012] In some possible implementations, the limiting device includes a sliding groove disposed on the slider and communicating with the slot, a slot disposed on the insert block and cooperating with the sliding groove, and a limiting member slidably mounted on the slider and cooperating with the slot at one end; the limiting member is elastically connected to the slider.

[0013] In some possible implementations, the limiting member includes a limiting rod with one end extending into the sliding groove, a wedge block connected to the end of the limiting rod near the insert block, a pull block disposed at the other end of the limiting rod, and an elastic member with one end connected to the pull block and the other end connected to the outer side of the slider; the elastic member is fitted on the outside of the limiting rod; in the initial state, the distance between the two sets of wedge blocks is less than the width of the insert block.

[0014] In some possible implementations, the two sets of wedges are positioned close to each other to form a figure-eight shaped chamber, with the large end opening located on the side near the contactor.

[0015] In some possible implementations, the slider is provided with a guide groove that communicates with the sliding groove, and the wedge is provided with a guide block that slides with the guide groove.

[0016] In some possible implementations, the locking element includes a through groove disposed on the mounting block and parallel to the slide groove, a through hole disposed on the slider and communicating with the through groove, a screw rod fitted in the through hole and with both ends located outside the through groove, and two sets of nuts screwed to the screw rod and located outside the mounting block, the mounting block being located between the two sets of nuts; the through groove and the slide groove are interconnected.

[0017] In some possible implementations, a cabinet door that is hinged to the cabinet body and used for opening and closing the cabinet body is also included. The slide has a U-shaped cross-section and the opening is located on the side near the cabinet door. The opening of the slot is located on the same side as the opening of the slide.

[0018] In some possible implementations, there are multiple sets of sliders in each set of slide grooves, each slidingly engaging with the slide groove, and multiple sets of locking elements, each corresponding to one of the sliders.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention aligns the plug on the contactor with the slot on the slider. When the plug is inserted into the slot in the slider, the wedge block will drive the limit rod to move. When the plug is fully inserted into the slot, the wedge block will be pushed into the slot by the force of the elastic element. This makes it easy to install the contactor and effectively improves the work efficiency of contactor installation. In addition, the contactor can achieve shock absorption by contacting the buffer pad on the front end of the mounting block, which protects the contactor.

[0021] This invention allows the slider to move by moving the screw in the through groove, thereby adjusting the position of the contactor. After adjusting the position of the contactor, the nut can be turned so that it abuts against the mounting block, thus fixing the position of the slider. This allows the contactor to be easily adjusted for use in different positions. Attached Figure Description

[0027] The present invention will now be described in detail.

[0028] like Figures 1-3 As shown;

[0029] A shock-absorbing structure for a power distribution cabinet contactor that is easy to install includes a cabinet 1, several sets of mounting blocks 2 evenly distributed inside the cabinet 1, a slider 3 that slides and engages with the mounting blocks 2 for mounting a contactor 4, and a locking member for fixing the slider 3 to the mounting blocks 2; a sliding groove 201 is provided on the slider 3 that slides and engages with the slider 3, and the slider 3 is located in the sliding groove 201 and slides and engages with the sliding groove 201; a buffer pad 203 is provided on the side of the mounting block 2 near the contactor 4.

[0030] Specifically, several sets of mounting blocks 2 are arranged vertically at equal intervals inside the cabinet 1; each set of sliding blocks 3 in the sliding groove 201 consists of multiple sets and slides in cooperation with the sliding groove 201 respectively; the locking components consist of multiple sets and are arranged one-to-one with the sliding blocks 3, so that each set of sliding blocks 3 can slide to the designated position according to the installation position requirements of the contactor 4, and then the sliding blocks 3 are locked and fixed to the mounting blocks 2 by locking; then the contactor 4 can be installed.

[0031] By setting the buffer pad 203, the shock absorption effect can be achieved, which protects the contactor 4.

[0032] In some possible implementations, in order to effectively connect the slider 3 and the contactor 4, a mounting assembly for detachably mounting the contactor 4 is provided on the slider 3. The mounting assembly includes a slot 303 disposed on the slider 3 and inserted into the contactor 4, a plug 304 inserted into the slot 303 and connected to the contactor 4, and a limiting device slidably mounted on the slider 3 with one end extending into the slot 303 and abutting against the plug 304. The limiting device consists of two sets and is arranged opposite to each other along the insertion direction of the plug 304.

[0033] In use, the plug 304 is first connected and fixed to the rear end face of the contactor 4, and then the plug 304 is inserted into the slot 303. After the plug 304 is inserted into the designated position, the movement of the plug 304 is restricted by the limiting device, so that the plug 304 and the slider 3 form a whole, thus making the contactor 4 and the slider 3 connected and fixed.

[0034] In some possible implementations, the limiting device includes a sliding groove 305 disposed on the slider 3 and communicating with the slot 303, a retaining groove 3041 disposed on the insert block 304 and used in conjunction with the sliding groove 305, and a limiting member slidably mounted on the slider 3 and used in conjunction with the retaining groove 3041 at one end; the limiting member is elastically connected to the slider 3; the moving direction of the limiting member is perpendicular to the moving direction of the insert block 304; the retaining groove 3041 is disposed on the side of the insert block 304 near the sliding groove 305;

[0035] In the initial state, the two sets of limiting members will extend into the slot 303 at one end, and the distance between them is less than the width of the insert 304. When the insert 304 is inserted into the slot 303, the two limiting members will be squeezed and move away from the slot 303. When the slot 3041 and the sliding groove 305 are facing each other and connected to each other, since the limiting members and the slider 3 are elastically connected, under the elastic force, the end of the limiting members that is close to each other will move towards the slot 3041 and lock the insert 304, restricting its movement. This allows the insert 304 and the slider 3 to be connected to form a whole, completing the installation of the contactor 4.

[0036] In some possible implementations, in order to effectively fix the contactor 4 by cooperating with the limiting member and the insert block 304, the limiting member includes a limiting rod 307 with one end extending into the sliding groove 305 and slidingly cooperating with the slider 3, a wedge block 306 connected to the end of the limiting rod 307 near the insert block 304, a pull block 308 disposed at the other end of the limiting rod 307 and located outside the slider 3, and an elastic member 309 with one end connected to the pull block 308 and the other end connected to the outer side of the slider 3; the elastic member 309 is fitted on the outside of the limiting rod 307; in the initial state, the distance between the two sets of wedge blocks 306 is less than the width of the insert block 304; the side of the two sets of wedge blocks 306 away from the limiting rod 307 is an inclined surface, and the inclined surfaces of the two sets of wedge blocks 306 cooperate with each other to form a figure-eight shaped chamber connected to the slot 303, and the large end opening of the figure-eight shaped chamber is disposed on the side near the contactor 4.

[0037] When the insert block 304 is not inserted, the elastic element 309 is in its initial state, and the two sets of wedge blocks 306 are located in the slot 303. After the insert block 304 is inserted into the figure-eight shaped cavity, the two sets of wedge blocks 306 will approach each other and abut against the outer side of the insert block 304. As the insert block 304 moves, it continuously squeezes the wedge blocks 306, and the two sets of wedge blocks 306 will move away from the insert block 304. The elastic element 309 will change from its initial state to a stretched state. When the slot 3041 and the sliding groove 305 are directly opposite and connected to each other, the slot 3041 and the sliding groove 305 will form a sliding cavity. The wedge block 306 will not be squeezed, and the elastic element 309 will return from the stretched state to its initial state. This allows the wedge block 306 to move towards the insert block 304 under the action of the limiting rod 307 and insert into the slot 3041, thereby achieving the limiting and fixing of the insert block 304.

[0038] In some possible implementations, in order to effectively guide the sliding direction of the wedge block 306, a guide groove 310 communicating with the sliding groove 305 is provided on the slider 3, and a guide block 311 slidingly engaging with the guide groove 310 is provided on the wedge block 306.

[0039] In some possible implementations, in order to effectively lock and fix the mounting block 2 and the slider 3;

[0040] The locking component includes a through groove 202 disposed on the mounting block 2 and parallel to the slide groove 201, a through hole disposed on the slider 3 and communicating with the through groove 202, a screw 301 fitted in the through hole and with both ends located outside the through groove 202, and two sets of nuts 302 screwed to the screw 301 and located outside the mounting block 2. The mounting block 2 is located between the two sets of nuts 302. The through groove 202 and the slide groove 201 are interconnected.

[0041] In some possible implementations, a cabinet door 101 is also included, which is hinged to the cabinet body 1 and used to open and close the cabinet body 1. The slide 201 has a U-shaped cross-section and the opening is located on the side near the cabinet door 101. The opening of the slot 303 is located on the same side as the opening of the slide 201.

[0042] Example 1:

[0043] This utility model provides a shock-absorbing structure for a power distribution cabinet contactor that is easy to install, including a cabinet body 1, a cabinet door 101 that is rotatably mounted on the cabinet body 1 via a hinge, a plurality of mounting blocks 2 that are evenly distributed inside the cabinet body 1, a buffer pad 203 that is disposed on the side of the mounting block 2 near the cabinet door 101, a slide groove 201 that is disposed on the mounting block 2 and has an opening on the side near the cabinet door 101, a through groove 202 that is disposed on the mounting block 2 and communicates with the slide groove, a slider 3 that is located in the slide groove 201 and slides in cooperation with the slide groove 201, a contactor 4 that is detachably connected to the side of the slider 3 near the cabinet door 101, a locking member for locking the slider 3 and the mounting block 2, and a mounting assembly that is disposed on the slider 3 and is used for inserting the contactor 4.

[0044] The mounting components include a slot 303 on the side of the slider 3 near the cabinet door 101, two sets of sliding grooves 305 on both sides inside the slot 303 and communicating with the slot 303, a wedge block 306 located in the sliding groove 305 and slidingly engaged with the sliding groove 305, a limiting rod 307 fixedly connected to the end of the wedge block 306 away from the slot 303, an insert block 304 slidingly engaged with the slot 303, and a slot 3041 set on both sides of the insert block 304 and used to engage with the sliding groove 305. The insert block 304 is mounted on the side of the contactor 4 near the mounting block 2.

[0045] A limiting rod 307 is provided on the side of the wedge block 306 away from the slot 3041; a through hole is provided on the slider 3 for the limiting rod 307 to pass through; a pull block 308 is fixedly connected to the other end of the limiting rod 307; an elastic element 309 is sleeved on the outside of the limiting rod 307, one end of the elastic element 309 is fixedly connected to the slider 3, and the other end of the elastic element 309 is fixedly connected to the pull block 308.

[0046] In use, move the slider 3 within the slide groove 201. After moving it to the designated position, lock the mounting block 2 and the slider 3 together using the locking mechanism; then install the contactor 4.

[0047] In the initial state, the wedge block 306 will pass through the sliding groove 305 and be located in the slot 303. The two sets of wedge blocks 306 will approach each other on one side to form a figure-eight shaped chamber. The large end of the figure-eight shaped chamber is located on the side close to the contactor 4.

[0048] During the installation of contactor 4, the insert block 304 installed on contactor 4 will first enter the large end of the figure-eight shaped chamber and continue to insert, making contact and pressing with the wedge block 306, causing the two sets of wedge blocks 306 to move away from each other. The elastic element 309 will change from the initial state to the tensile state. Due to the presence of the slot 3041, when the insert block 304 continues to move into the slot 303, and the slot 3041 connects with the sliding groove 305, the wedge block 306 will no longer be pressed by the insert block 304. The elastic element 309 will return from the tensile state to the initial state, thereby causing the two sets of wedge blocks 306 to approach each other and enter the slot 3041. At this time, the insert block 304 will be limited and fixed by the cooperation of the limiting rod 307 and the wedge block 306.

[0049] Preferably, the elastic element 309 is a compression spring.

[0050] Furthermore, a guide groove 310 communicating with the sliding groove 305 is provided on the slider 3. A guide block 311 is slidably connected in the guide groove 310. The guide block 311 is fixedly connected to the wedge block 306. The guide groove 310 and the guide block 311 guide the sliding direction of the wedge block 306 so that it can only slide along the axial direction of the limiting rod 307.

[0051] As can be seen from the above, when in use, by aligning the plug 304 on the contactor 4 with the slot 303 on the slider 3 and inserting the plug 304 into the slot 303 in the slider 3, the wedge block 306 will drive the limit rod 307 to move. When the plug 304 is fully inserted into the slot 303, the wedge block 306 will be pushed into the slot 3041 under the force of the elastic element 309. This makes it easy to install the contactor 4, effectively improving the work efficiency of the contactor 4 installation. In addition, the contactor 4 can achieve the effect of shock absorption by contacting the buffer pad 203 on the front end of the mounting block 2, thus protecting the contactor 4.

[0052] The locking mechanism includes a through groove 202 disposed on the mounting block 2 and parallel to the slide groove 201, a through hole disposed on the slider 3 and communicating with the through groove 202, a screw 301 fitted into the through hole and with both ends located outside the through groove 202, and two sets of nuts 302 screwed to the screw 301 and located outside the mounting block 2; the mounting block 2 is located between the two sets of nuts 302; the longitudinal direction of the through groove 202 is consistent with the longitudinal direction of the slide groove 201, and the two are interconnected; the through groove 202 penetrates through the upper and lower surfaces of the mounting block 2; when the slide groove 201 is closed, the locking mechanism is engaged with the slider 3. When the bottom of block 3 abuts against the bottom of slide groove 201, the through hole communicates with the through groove 202; the movement of slider 3 in slide groove 201 allows slider 3 to slide to a designated position for installation. After moving to the designated position, screw 301 is fitted into the through hole and both ends of screw 301 pass through the entire through groove 202. Then, the nut 302 is tightened so that the two sets of nuts 302 abut against the upper and lower surfaces of mounting block 2. The slider 3 and mounting block 2 are clamped and fixed through the cooperation of the two sets of nuts 302 and screw 301.

[0053] As can be seen from the above, when in use, the slider 3 can be moved by moving the screw 301 in the through groove 202, thereby adjusting the position of the contactor 4. After adjusting the position of the contactor 4, the nut 302 can be turned so that the nut 302 contacts the surface of the mounting block 2, thereby fixing the position of the slider 3. This allows the contactor 4 to be easily adjusted for use in different positions.

[0054] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
