A fixing plate is provided on one side of the upper outer wall of the support plate. Equally spaced parallel sliding grooves are formed on one side of the upper outer wall of the support plate, and sliders are movably installed inside the sliding grooves. Shock-absorbing pads are symmetrically installed on one side of the outer wall of the limiting rods, with two shock-absorbing pads located at the upper and lower ends of the support plate, respectively. This invention, by setting up a base plate, support plate, and fixing plate, achieves the effect of improving the service life of the equipment, avoiding stripping and loosening of bolt connections, thereby extending the service life of the equipment, facilitating subsequent maintenance, and improving the practicality of the equipment.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0005] The main body of the box-type water supply unit is often directly on the ground. The installation process requires repeated drilling and positioning for box-type water supply units of different lengths and widths, which is very cumbersome.

[0006] Therefore, in response to the above problems, the applicant provides a box-type negative pressure-free water supply device for municipal building water supply. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a box-type negative pressure-free water supply equipment for municipal building water supply.

[0008] This application provides a box-type negative pressure-free water supply device for municipal building water supply, which adopts the following technical solution:

[0009] A box-type negative pressure-free water supply device for municipal building water supply includes an "I"-shaped sliding plate A, an "I"-shaped sliding plate B, a positioning mechanism, and a shock absorption mechanism. The positioning mechanism includes a circular ring, a fixing rod, and a spring. The fixing rod is sleeved with the spring, and the top of the spring contacts the bottom of the circular ring.

[0010] The shock absorption mechanism includes a first connector, a shock absorber, and a second connector, with a shock absorber installed between the first connector and the second connector.

[0011] Optionally, there are two "I"-shaped slide plates A and two "I"-shaped slide plates B. Two "I"-shaped sliding blocks are slidably connected to each of the two "I"-shaped slide plates A. Multiple insertion holes are passed through the bottom of each of the two "I"-shaped slide plates A. Holes are vertically passed through each of the four "I"-shaped sliding blocks. A circular ring is fixedly connected to the top of each hole.

[0012] Optionally, a plug is fixedly connected to the bottom end of the fixing rod, and a spring is contacted on the top surface of the plug. The spring is inserted into one of the sockets, and an "L"-shaped pull tube is fixedly connected to the top of the fixing rod. The "L"-shaped pull tube is sleeved into the limiting hole opened in the sleeve.

[0013] Optionally, the bottom of each of the two I-shaped slide plates B has multiple insertion holes, and two I-shaped sliding blocks are slidably connected to each of the two I-shaped slide plates B. The four I-shaped sliding blocks on the I-shaped slide plate B are fixedly connected to the I-shaped slide plate A in pairs.

[0014] Optionally, the two fixing rods on the two I-shaped slide plates B are jointly fixedly connected to an inverted U-shaped pull rod.

[0015] Optionally, the top surface of the I-shaped sliding block on the I-shaped slide plate A is fixedly connected to two support frames, each of which is fixedly connected to a fixed shaft.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a box-type negative pressure-free water supply device for municipal building water supply.

[0029] like Figure 1-6 As shown, a box-type negative pressure-free water supply equipment for municipal building water supply includes an "I"-shaped sliding plate A1, an "I"-shaped sliding plate B7, a positioning mechanism, and a shock absorption mechanism. The positioning mechanism includes a circular ring 20, a fixing rod 3, and a spring 4. The fixing rod 3 is sleeved with the spring 4, and the top of the spring 4 contacts the bottom of the circular ring 20.

[0030] The damping mechanism includes connector 9, shock absorber 10 and connector 11, with shock absorber 10 installed between connector 9 and connector 11.

[0031] Please see Figure 2 and Figure 5 There are two "I"-shaped slide plates A1 and B7. Two "I"-shaped sliding blocks 2 are slidably connected to each of the two "I"-shaped slide plates A1. Multiple insertion holes 100 are passed through the bottom of each of the two "I"-shaped slide plates A1. Holes are vertically passed through each of the four "I"-shaped sliding blocks 2. A circular ring 20 is fixedly connected to the top of each hole. A plug 30 is fixedly connected to the bottom of the fixing rod 3. A spring 4 is in contact with the top surface of the plug 30. The spring 4 is inserted into one of the insertion holes 100. An "L"-shaped pull tube 5 is fixedly connected to the top of the fixing rod 3. The "L"-shaped pull tube 5 is sleeved into the limiting hole 60 opened in the sleeve 6. Scale values ​​are engraved on both "I"-shaped slide plates A1 and B7.

[0032] Please refer to Figure 2 and Figure 5 The bottom of each of the two I-shaped sliding plates B7 has multiple insertion holes 100. Two I-shaped sliding blocks 2 are slidably connected to each of the two I-shaped sliding plates B7. The four I-shaped sliding blocks 2 on the I-shaped sliding plate B7 are fixedly connected to the I-shaped sliding plate A1 in pairs. The fixing rods 3 on the two I-shaped sliding plates B7 are fixedly connected to the inverted U-shaped pull rods 8. The structural insertion holes 100, I-shaped sliding blocks 2, circular rings 20, fixing rods 3, plugs 30 and springs 4 on the two I-shaped sliding plates A1 are also provided with the same structure on the two I-shaped sliding plates B7. However, the sliding of the I-shaped sliding blocks 2 on the two I-shaped sliding plates B7 does not require changing the distance between the two I-shaped sliding blocks 2, so it can be done by the inverted U-shaped pull rods 8.

[0033] Please see Figure 2 and Figure 6Two support frames 90 are fixedly connected to the top surface of the I-shaped sliding block 2 on the I-shaped slide plate A1. Each support frame 90 is fixedly connected to a fixed shaft 91. The fixed shaft 91 is sleeved onto the bottom end of the shock absorber 10. A fixed shaft 111 is rotatably connected to the top end of the shock absorber 10. Support frames 110 are fixedly connected to both ends of the fixed shaft 111. The support frames 90 and fixed shafts 91 together form a connector 9, and the support frames 110 and fixed shafts 111 together form a connector 11. The eight support frames 110 are connected in pairs to a fixed limit block 12. The box-type water supply device body 13 is placed at the corner of the four limit blocks 12. The box-type water supply device body 13 is connected to an external power source. Since it is existing technology, its working principle will not be described in detail here. It mainly uses eight shock absorbers 10 set at the bottom corner of the box-type water supply device body 13 to reduce vibration, that is, to avoid the vibration generated by the operation of the electrical components in the box-type water supply device body 13, which would reduce the service life of the equipment.

[0034] The implementation principle of a box-type negative pressure-free water supply device for municipal building water supply in this application embodiment is as follows:

[0035] The sliding of the I-shaped sliding blocks 2 on the two I-shaped sliding plates A1 can be adjusted according to the length of the box-type water supply device body 13. At the same time, the insertion holes 100 provided on the I-shaped sliding plates A1 are opened for the length of the box-type water supply device body 13 of different lengths.

[0036] The sliding of the I-shaped sliding block 2 on the two I-shaped slide plates B7 can be adjusted according to the width of the box-type water supply device body 13. At the same time, the insertion hole 100 provided on the I-shaped slide plate B7 is opened for the length of the box-type water supply device body 13 of different widths. The adjustment method of the I-shaped sliding block 2 on the I-shaped slide plate A1 is as follows.

[0037] Lift the sleeve 6 upwards. The sleeve 6 moves the "L"-shaped pull tube 5 and the fixing rod 3 upwards, the spring 4 contracts, and the plug 30 disengages from the socket 100. At this time, pull the sleeve 6 to one side and slide the "I"-shaped sliding block 2 on the "I"-shaped sliding groove plate A1 to the corresponding scale value on the "I"-shaped sliding groove plate A1. Then release the sleeve 6. Under the rebound of the spring 4, the plug 30 is inserted into the socket 100. At this time, the state of the "I"-shaped sliding block 2 is fixed. When it is necessary to locate the length of the box-type water supply device body 13, the operation process is as follows:

[0038] Pull the inverted "U"-shaped lever 8 to disengage the plug 30 from the socket 100. Slide the "I"-shaped sliding block 2 on the "I"-shaped slide plate B7 to the marked position on the "I"-shaped slide plate B7 and stop. Release the plug 30 and insert it into the socket 100 for positioning. This is the same as the width adjustment described above, except that when the "I"-shaped sliding block 2 on the "I"-shaped slide plate B7 slides, the "I"-shaped slide plate A1, the "I"-shaped sliding block 2, and the "L"-shaped pull cylinder 5 will slide synchronously, and the "L"-shaped pull cylinder 5 will extend and retract in the sleeve 6 at the same time.

[0039] The eight shock absorbers 10 installed at the bottom corner of the box-type water supply device body 13 serve to reduce vibration, thereby preventing the vibration generated by the operation of electrical components in the box-type water supply device body 13 from reducing the service life of the equipment.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
