Description

Technical Field

[0001] This utility model relates to the field of desk manufacturing technology, and in particular to a welding device for rotating and lifting student desks by hand. Background Technology

[0002] Desks are desks used by students. They originated from the octagonal tables in the earliest schools and were used in schools. The desks used for learning in schools should be standardized as desks.

[0003] Welding equipment is used during the production of school desks to weld the various parts of the desk into a single unit for easy use. However, existing welding equipment (such as the one provided in the instruction manual)... Figure 1 As shown, in order to facilitate the welding of various sizes of desk components, this device uses a pneumatic rod to push the welding frame to slide on the slide rail for adjustment, thereby realizing the welding of various sizes of desk components. However, during the long-term sliding process between the slide rail and the slider, if lubricating oil is not added in time, the resistance between the slider and the slide rail will be large. Since the pneumatic rod is used for pushing, it is not possible to clearly perceive the running resistance between the slide rail and the slider, so it is difficult to judge whether there is insufficient lubrication. If continued use is made, the slider and the slide rail will not be able to slide and will be scrapped, resulting in economic losses. Therefore, we propose a welding device for student desks that rotates and is pulled up and down by hand. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. In existing welding equipment, the slide rail and slider slide together for a long time. If lubricating oil is not added in time, the resistance between the slider and the slide rail will be large. Since the pneumatic rod is used for propulsion, it is impossible to clearly perceive the running resistance between the slide rail and the slider. Therefore, it is difficult to determine whether there is insufficient lubrication. If continued use is made, the slider and slide rail will not be able to slide and will be scrapped, resulting in economic losses. The invention aims to achieve self-lubrication.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding device for rotating and lifting student desks includes two sliding seats. Several sliding grooves are provided on the side walls of both sliding seats. A humidity sensing module is provided inside the sliding grooves and near the back side. A self-lubricating device is provided inside both sliding seats. A sliding block is provided inside the sliding grooves.

[0007] Preferably, the self-lubricating device includes a cavity, the cavity is provided with a sealing partition plate, the rear end of the sealing partition plate is provided with a storage chamber, and the front end of the sealing partition plate is provided with an installation chamber.

[0008] Preferably, a sealing plate is provided on the outer side of the cavity, and an oil inlet is provided on the sealing plate, which is connected to the interior of the storage chamber.

[0009] Preferably, the installation chamber is equipped with a lubrication structure, and the pipes of the lubrication structure can be transported to a designated location through a pipe channel located on the back side of the installation chamber.

[0010] Preferably, the lubrication structure includes an oil pump, a flow divider is provided at the connection of the oil pump, an oil inlet pipe is provided at the rear end of the flow divider, an L-shaped oil outlet pipe is provided at the top of the flow divider, and an electromagnetic valve is provided on the L-shaped oil outlet pipe.

[0011] Preferably, the L-shaped oil outlet pipe can distribute lubricating oil to each sliding groove through several branch pipes at the end.

[0012] Preferably, a first mounting seat is provided on the top of a plurality of the sliding blocks, a second mounting seat is provided on the back side of the first mounting seat, and a support block is provided at the bottom of the second mounting seat.

[0013] Preferably, the humidity sensing module is installed inside the sliding groove through a mounting hole on the inner side of the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, through the design of a self-lubricating device and a humidity sensing module, the humidity sensing module can monitor the humidity inside the sliding groove. When the humidity is detected to be too low, the self-lubricating device will start, and the oil pump will draw the lubricating oil inside the storage chamber to the distribution seat through the oil inlet, and deliver the lubricating oil to each sliding groove through the L-shaped oil outlet pipe at the top. After the delivery is completed, since the sliding block will slide on the sliding groove, the lubricating oil on the sliding groove can be carried to the entire sliding groove, and the sliding block and the sliding groove will be fully lubricated, avoiding the problem of excessive resistance between the sliding block and the sliding groove, which would cause severe wear and lead to excessive sliding resistance or scrap.

Each sliding seat 1 has a self-lubricating device 4 inside, and a sliding block 5 inside each sliding groove 2. Through the design of the self-lubricating device 4 and the humidity sensing module 3, the humidity sensing module 3 can monitor the humidity inside the sliding groove 2. When the detected humidity is too low, [the device will detect a problem]. The self-lubricating device 4 will start, and the oil pump 471 will draw the lubricating oil inside the storage chamber 43 to the distributor seat 472 through the oil inlet 46, and deliver the lubricating oil to each sliding groove 2 through the L-shaped oil outlet pipe 474 at the top. After the delivery is completed, since the sliding block 5 will slide on the sliding groove 2, the lubricating oil on the sliding groove 2 can be carried to the entire sliding groove 2, and the sliding block 5 and the sliding groove 2 will be fully lubricated, so as to avoid excessive resistance between the sliding block 5 and the sliding groove 2, which would cause severe wear and lead to excessive sliding resistance or scrap.

The sealing dividing plate 42 divides the space of the cavity 41 into two parts, namely the storage chamber 43 and the installation chamber 44. The storage chamber 43 is used to store lubricating oil, and the installation chamber 44 is used to install equipment.

[0032] A sealing plate 45 is provided on the outside of the cavity 41. An oil inlet 46 is provided on the sealing plate 45. The oil inlet 46 is connected to the inside of the storage chamber 43.
