[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-5 An automatic hydraulic pump with a safety device is shown, comprising a pump body 1, a fuel tank 2 for storing oil being arranged at the bottom end of the pump body 1, a pressure gauge 4 for oil pressure monitoring being arranged at the top end of the fuel tank 2, a protective mechanism for protecting the surface of the pressure gauge 4 being arranged outside the pressure gauge 4, the protective mechanism comprising a protective assembly and an installation assembly, the protective assembly comprising a protective panel 6, the installation assembly comprising a installation cover 7, the protective panel 6 being arranged inside the installation cover 7, and the installation cover 7 being arranged on the outer wall of the pressure gauge 4.

[0021] Specifically, the bottom end of the pump body 1 is fixedly connected to the top end of the oil tank 2, a reversing control valve 3 for controlling the oil flow direction is fixedly connected to the top end of the oil tank 2, a pressure gauge 4 is arranged on the top end of the reversing control valve 3, and a handle 5 for facilitating the lifting of the oil tank 2 is fixedly connected to the top end of the oil tank 2.

[0022] Furthermore, the pump body 1, the oil tank 2, the reversing control valve 3, the pressure gauge 4 and the handle 5 constitute an ultra-high pressure electric hydraulic oil pump of the existing model BD-ZB63. The pressure gauge 4 is used to display the oil pressure and plays a role in safety monitoring.

[0023] Specifically, a circular through groove is provided on the front of the mounting cover 7, a slot is provided on the bottom of the mounting cover 7, the mounting cover 7 is sleeved on the outer wall of the pressure gauge 4, the outer wall of the mounting cover 7 is provided with a mounting part for fixing the mounting cover 7, the mounting part includes a positioning bolt 8, the outer wall of the mounting cover 7 is provided with a first threaded hole 11 for threaded insertion and connection of the positioning bolt 8, and one end of the positioning bolt 8 is fixedly connected to a protective pad 9 for protecting the outer wall of the pressure gauge 4.

[0024] Furthermore, the mounting cover 7 is sleeved on the outer wall of the pressure gauge 4. The function of the slot is to prevent the mounting cover 7 from colliding with the connecting pipe at the bottom end of the pressure gauge 4 when the mounting cover 7 is sleeved on the outer wall of the pressure gauge 4, so as to ensure that the mounting cover 7 does not interfere with the connecting pipe. The thread on the inner wall of the first threaded hole 11 is meshed with the thread on the outer wall of the positioning bolt 8. Three positioning bolts 8 are arranged in an equidistant ring around the mounting cover 7. The number of the first threaded holes 11 corresponds to the number of the positioning bolts 8. The protective pad 9 is fixedly connected to the opposite end of the positioning bolt 8 by gluing. The protective pad 9 is made of rubber material. By rotating the positioning bolt 8, the protective pad 9 is gradually close to the outer wall of the pressure gauge 4. Through the symmetrically arranged positioning bolts 8, the outer wall of the pressure gauge 4 is tightly attached in a triangular manner, so that the mounting cover 7 is stably fixed on the outside of the pressure gauge 4. The rubber material of the protective pad 9 can prevent the positioning bolt 8 from causing damage to the outer wall of the pressure gauge 4.

[0026] Furthermore, a circular hole is provided on the front of the limiting ring 14, and the size of the circular hole is 0.7 times the size of the protective panel 6, so that the limiting ring 14 will not affect the data of the pressure gauge 4 observed through the protective panel 6 while limiting the protective panel 6 from sliding out of the circular through groove. The protective panel 6 adopts a transparent acrylic plate, and the protective panel 6 adopts a circular plate. The mounting groove 13 is an arc groove, and both ends of the mounting groove 13 extend to the position of half the height of the mounting cover 7, so that the protective panel 6 can easily enter and exit the mounting groove 13. The second threaded hole 12 is provided in two groups, which are symmetrically opened on both sides of the bottom of the front side of the mounting cover 7. The second threaded hole 12 passes through the mounting groove 13, and the second threaded hole 12 passes through the mounting groove 13. The threads on the inner walls of the second threaded holes 12 are meshed with the threads on the outer walls of the limiting bolts 10, so that by inserting the limiting bolts 10 threadedly into the second threaded holes 12, a restriction can be formed on the bottom end of the protective panel 6 to prevent the protective panel 6 from falling off. During long-term use, if the protective panel 6 is damaged, the limiting bolts 10 can be removed and the damaged protective panel 6 can be taken out of the mounting groove 13 for replacement. The new protective panel 6 can be inserted into the mounting cover 7 from the mounting groove 13, and the limiting bolts 10 can be threadedly inserted into the second threaded holes 12. The protective panel 6 can be reinstalled to ensure that the glass surface of the pressure gauge 4 is not damaged.
