[0002] A hydraulic solenoid valve is a basic automation component for controlling fluids. Specifically, it is a type of directional control valve, which is mainly used to control the on / off flow of oil or change the direction of oil flow.

[0003] Prior art, such as the patent with publication number CN204647502U, discloses a solenoid valve and a low-power solenoid valve, which has a valve body, the valve body forming an operating chamber; a valve core, wherein the valve core is movably arranged in the operating chamber; and an electromagnetic drive device, wherein the electromagnetic drive device is arranged on the valve core, wherein the electromagnetic drive device is suitable for being electrically connected to a power source, wherein the electromagnetic drive device includes a magnetic field generating unit, a passive component and a circuit controller, wherein the magnetic field generating unit forms a driving chamber, the passive component is arranged in the driving chamber, wherein the driving chamber is communicated with the operating chamber and the passive component is connected to the valve core, wherein the circuit controller is electrically connected to the magnetic field generating unit and the power source respectively.

[0004] The existing technology still has shortcomings:

[0005] The hydraulic solenoid valves in the prior art are all fixed by opening a mounting hole on the upper surface thereof, and using bolts to pass through the mounting hole to thread the bolts and the integrated block. However, when in use, the bolts are often unable to be separated from the integrated block due to thread slippage of the bolt threads or thread slippage on the integrated block. In addition, the hydraulic solenoid valve blocks the connection between the bolt and the integrated block, making it difficult to unscrew the bolts and remove the hydraulic solenoid valve, which affects the disassembly, maintenance, installation and use of the hydraulic solenoid valve. For this reason, a hydraulic solenoid valve is proposed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a hydraulic solenoid valve, which is convenient for disassembly, installation and use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic solenoid valve, including a solenoid valve body, a plurality of sockets are provided on the middle upper surface of the solenoid valve body, a limiting slide groove is provided on the inner wall of the socket, a clearance hole penetrating to the outside of the solenoid valve body is provided on the inner bottom surface of the limiting slide groove, a bolt support unit is slidably connected in the socket and the limiting slide groove, the bolt support unit includes a bolt insert slidably connected in the socket, a limiting strip is fixedly connected to the outer wall of the bolt insert, the limiting strip is slidably connected in the limiting slide groove, and the limiting strip is movably connected to the clearance hole.

[0008] Preferably, one side inner wall of the clearance hole is flush with one side inner wall of the limiting sliding groove.

[0009] Preferably, the length of the bolt insert is greater than the length of the insert hole.

[0010] Preferably, the length of the limiting strip is equal to the length of the limiting sliding groove.

[0011] Preferably, a countersunk hole is formed on the upper end surface of the bolt insert, and a hexagon socket bolt is used to fix the solenoid valve body, and the screw head portion of the bolt is located in the countersunk hole.

[0012] Preferably, a screw groove is provided on the outer wall of the upper end of the bolt insert, and the inner wall of the screw groove is a regular hexagonal structure.

[0013] Preferably, a plurality of threaded holes connected to the clearance hole are provided on both sides of the solenoid valve body, and a limit screw is threadedly connected in the threaded hole, and one end of the limit screw is inserted into the clearance hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model provides an insertion hole, a limiting slide groove and a clearance hole on the solenoid valve body. When the solenoid valve body needs to be fixed, the threaded insert and the limiting strip can be inserted from the insertion hole and the clearance hole to move the limiting strip into the limiting slide groove, and the threaded insert can be rotated to misalign the limiting strip with the clearance hole. At this time, the bolt used to fix the solenoid valve body can be passed through the bolt insert and connected to the integrated block to fix the solenoid valve body. At the same time, when the threaded hole on the integrated block or the thread on the bolt is stripped, the limiting strip can be rotated to correspond to the clearance hole. At this time, the solenoid valve body can slide out from the multiple threaded inserts and the limiting strip, thereby facilitating the disassembly of the solenoid valve body and the separation of the stripped bolt from the integrated block, thereby improving practicality.

[0016] 2. The utility model connects a limit screw that penetrates into the clearance hole to the solenoid valve body. The limit screw can block the clearance hole, so that when there is no need to remove the bolt support unit from the socket, the limit screw can restrict it, so as to facilitate the installation of the solenoid valve body and avoid loss.

[0017] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model.

[0024] 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 technical field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The hydraulic solenoid valve of this embodiment includes a solenoid valve body 1, a plurality of sockets 2 are provided on the middle upper surface of the solenoid valve body 1, a limiting slide groove 4 is provided on the inner wall of the socket 2, a clearance hole 5 penetrating to the outside of the solenoid valve body 1 is provided on the inner bottom surface of the limiting slide groove 4, a bolt support unit 3 is slidably connected in the socket 2 and the limiting slide groove 4, the bolt support unit 3 includes a bolt insert 31 slidably connected in the socket 2, a limiting strip 32 is fixedly connected to the outer wall of the bolt insert 31, the limiting strip 32 is slidably connected in the limiting slide groove 4, and the limiting strip 32 is movably connected to the clearance hole 5.

[0026] like Figure 1 , 3As shown in Figures 4 and 5, a hydraulic solenoid valve structure in the utility model is similar to an existing hydraulic solenoid valve structure, such as the solenoid valve and low-power solenoid valve disclosed in the patent with publication number CN204647502U. The main improvement of the utility model is to facilitate the disassembly and installation of the hydraulic solenoid valve. When the solenoid valve body 1 needs to be installed, the utility model first inserts a plurality of bolt support units 3 into the insertion hole 2. The insertion method is to insert one end of the bolt insert tube 31 and one end of the limit bar 32 into the solenoid valve body 1 from the lower end of the insertion hole 2 and the clearance hole 5 respectively, so that the bolt insert tube 31 is completely inserted into the insertion hole 2, and the limit bar 32 is completely inserted into the limit slide 4. At this time, the bolt insert tube 31 is rotated to make the limit bar 32 rotate to be misaligned with the clearance hole 5. The limit slide 4 restricts the limit bar 32 so that the bolt insert tube 31 will not slide out of the insertion hole 2. When the bolt is inserted into the bolt tube 31 and threadedly connected with the screw hole reserved on the external integrated block, the screw head of the bolt is squeezed tightly against the upper end of the bolt tube 31, and the installation of the solenoid valve body 1 and the integrated block can be realized. When the bolt used to fix the solenoid valve body 1 or the screw hole on the integrated block is stripped, the bolt tube 31 can be rotated, and the bolt tube 31 drives the limit bar 32 to rotate in the limit slide groove 4 until the limit bar 32 is rotated to correspond to the clearance hole 5. When multiple limit bars 32 are rotated to correspond to the clearance hole 5, the solenoid valve body 1 can be pulled up at this time, and then removed from the bolt tube 31 and the limit bar 32, so as to realize the disassembly of the solenoid valve body 1, and it is also convenient to separate the stripped bolt from the integrated block, and the screw head of the bolt can also be cut, and then the bolt tube 31 and the limit bar 32 can be recovered, so as to ensure the disassembly of the solenoid valve body 1 and improve the practicality.

[0027] like Figure 4 As shown, the inner wall of one side of the clearance hole 5 is flush with the inner wall of one side of the limiting slide groove 4; when the limiting strip 32 turns to contact the inner wall of the limiting slide groove 4 adjacent to the clearance hole 5, the limiting strip 32 can be moved out of the limiting slide groove 4 through the clearance hole 5, so as to facilitate the control of the position of the limiting strip 32 corresponding to the position of the clearance hole 5, and facilitate the insertion and removal of the bolt insert 31 and the socket 2.

[0028] like Figure 1 , 3 As shown in Figures 4 and 5, the length of the bolt insert 31 is greater than the length of the socket 2; after the bolt insert 31 is inserted into the socket 2, part of it extends from the socket 2 to the outside of the solenoid valve body 1. By rotating the bolt insert 31 outside the solenoid valve body 1, it is convenient to bear force and adjust the position of the limit strip 32.

[0029] like Figure 3-5As shown, the length of the limit strip 32 is equal to the length of the limit slot 4; after the limit strip 32 is moved into the limit slot 4, the limit slot 4 restricts the limit strip 32 so that the bolt insert 31 cannot move up and down, thereby increasing the restriction on the bolt insert 31 and ensuring stability.

[0030] like Figure 5 As shown, a countersunk hole 34 is provided on the upper end surface of the bolt insert 31, and a hexagon socket bolt is used to fix the solenoid valve body 1, and the screw head of the bolt is located in the countersunk hole 34; after the bolt for fixing the solenoid valve body 1 is connected to the integrated block, the screw head of the bolt enters the countersunk hole 34 and does not protrude, thereby preventing the outer wall of the bolt head from touching the outside and causing the bolt to loosen, thereby ensuring the installation strength of the solenoid valve body 1.

[0031] like Figure 5 As shown, a screw groove 33 is provided on the outer wall of the upper end of the bolt insert 31, and the inner wall of the screw groove 33 is a regular hexagonal structure; by utilizing the screw groove 33 with a regular hexagonal inner wall, a wrench can be used to rotate the bolt insert 31, thereby avoiding the phenomenon that the bolt insert 31 is difficult to screw due to the damping generated by the bolt, thereby improving adaptability.

[0032] like Figure 2 , 4 As shown, both sides of the solenoid valve body 1 are provided with a plurality of threaded holes 6 connected with the clearance hole 5, and the threaded holes 6 are internally threadedly connected with limit screws 7, and one end of the limit screws 7 is passed through the clearance hole 5; after the bolt insert 31 is inserted into the insertion hole 2, the limit screws 7 are screwed into the threaded hole 6, so that one end of the limit screws 7 is passed through the clearance hole 5, and then the limit screws 7 are used to block the limit bar 32 to prevent the limit bar 32 from moving out of the clearance hole 5 again, thereby improving the stability of the installation.

[0033] Implementation steps in this embodiment: when the solenoid valve body 1 needs to be installed, first insert multiple bolt support units 3 into the socket 2. The insertion method is to insert one end of the bolt insert tube 31 and one end of the limit strip 32 into the solenoid valve body 1 from the lower end of the socket 2 and the clearance hole 5 respectively, so that the bolt insert tube 31 is fully inserted into the socket 2, and the limit strip 32 is fully inserted into the limit slide 4. At this time, the bolt insert tube 31 is rotated to make the limit strip 32 turn to be misaligned with the clearance hole 5. The limit slide 4 restricts the limit strip 32 so that the bolt insert tube 31 will not slide out of the socket 2, and the limit screw 7 is screwed into the threaded hole 6 so that one end of the limit screw 7 is inserted into the clearance hole 5, and then the limit strip 32 is blocked by the limit screw 7. At this time, the bolt passes through the bolt insert tube 31 and is threaded with the screw hole reserved on the external integrated block. When the bolt head 31 is connected, it squeezes the upper end of the bolt insert 31 tightly, and the solenoid valve body 1 and the integrated block are installed. When the bolt used to fix the solenoid valve body 1 or the screw hole on the integrated block is stripped, the limit screw 7 is first screwed out from the threaded hole 6 to cancel the obstruction of the clearance hole 5. At this time, the bolt insert 31 is rotated again, and the bolt insert 31 drives the limit bar 32 to rotate in the limit slide groove 4 until the limit bar 32 is rotated to correspond to the clearance hole 5. When multiple limit bars 32 are rotated to correspond to the clearance hole 5, the solenoid valve body 1 can be pulled up and then removed from the bolt insert 31 and the limit bar 32 to realize the disassembly of the solenoid valve body 1, and it is also convenient to separate the stripped bolt from the integrated block. The screw head of the bolt can also be cut, and then the bolt insert 31 and the limit bar 32 can be recycled.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
