Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to a mechanical locking and releasing mechanism, a mechanical electrical connection device and hoisting equipment. Background Art

[0002] At present, some equipment has large dimensions, and the vehicle-mounted lifting equipment is too high or too wide during lifting operations or transportation. The lifting equipment needs to be separated and released into two or more halves. When it arrives at the equipment use site, it needs to be assembled into a whole. In this way, the mechanical parts of the lifting equipment need to be separated and released or docked and locked.

[0003] At present, the mechanical docking locking and separation release of this type of lifting equipment is usually assisted by other equipment or devices for docking positioning, and then manually hook-locked docking or bolted fixing. However, some vehicle-mounted lifting equipment has problems such as a high separation and release position and a small space, which makes the docking locking position environment not conducive to personal safety and the operating efficiency is not high. Summary of the invention

[0004] In view of this, the present invention proposes a mechanical locking and releasing mechanism, a mechanical and electrical connection device and a lifting equipment. The two fixed seats are the two parts on the lifting equipment that need to be docked. The positioning head is inserted into the cone cylinder, and the locking wedge is inserted into the annular locking groove of the positioning head to fix the positioning head. At the same time, the locking rod is inserted into the locking hole and the cone cylinder is locked by rotation, and then the locking wedge is fixed by the cone cylinder to achieve stable mechanical docking and locking. When separation and release are required, the locking rod is rotated to align with the locking hole and move toward the cone cylinder, pushing the cone cylinder to make the locking wedge slide away from the annular locking groove, thereby loosening the positioning head and completing the separation and release action, thereby achieving rapid docking locking and separation and release actions, and can directly cooperate with the electric control drive to realize automatic action, without the need for manual auxiliary docking or separation, further reducing the risk of operation.

[0005] The technical solution of the present invention is achieved in this way:

[0006] In one aspect, the present invention provides a mechanical locking release mechanism, comprising a fixing seat, a cone, a locking wedge, a positioning head and a locking rod, wherein:

[0007] There are two fixing seats, and both have a locking surface, and the locking surfaces of the two fixing seats fit each other;

[0008] The cone is arranged in one of the two fixing seats, and a socket is provided on the locking surface of the fixing seat, the bottom surface of the cone faces the locking surface, a locking hole is provided on the axis of the cone, and the locking hole faces the socket;

[0009] The locking wedge is slidably arranged on the cone and the fixed seat, and the locking wedge can slide along the generatrix direction of the cone and parallel to the locking surface;

[0010] The positioning head is fixed on the locking surface of another fixing seat and inserted into the socket of the fixing seat where the cone is located. An annular locking groove is provided on the outside of the positioning head. The locking wedge is inserted into the annular locking groove to relatively fix the positioning head and the fixing seat where the locking wedge is located.

[0011] The locking rod is arranged on the fixing seat where the positioning head is located, and the central axis is perpendicular to the locking surface. The locking rod can rotate and axially move relative to the fixing seat where the positioning head is located. The locking rod is provided with a locking head and a supporting surface. The locking head is inserted into the locking hole and cooperates with the supporting surface to prevent the locking rod from axially moving relative to the cone. The locking head is adapted to the locking hole.

[0012] When the separation is released, the locking rod rotates and aligns the locking head with the locking hole, and pushes the cone to move through the abutting surface, so that the locking wedge slides out of the annular locking groove, and at the same time the locking head leaves the locking hole, the positioning head leaves the socket, and the locking surfaces of the two fixed seats are separated.

[0013] On the basis of the above technical solution, preferably, it also includes a driving slide, which is slidably arranged in the fixed seat where the locking rod is located and is transmission-connected to the locking rod, and the fixed seat is provided with a locking position, a preparatory position and a release position. When the driving slide is in the locking position, the locking head and the locking hole are misaligned, and the cone cylinder is relatively fixed to the fixed seat where it is located. When the driving slide is in the preparatory position, the locking head is opposite to the locking hole. When the driving slide is in the release position, the abutting surface on the locking rod pushes the cone cylinder to move to the side away from the locking surface.

[0014] Further preferably, a pushing surface and a tightening surface are provided on the driving slide, the pushing surface is in contact with an end of the locking rod away from the locking head, the pushing surface is used to push the locking rod to move toward the fixed seat where the cone cylinder is located, and the locking rod also includes a limiting portion, when the driving slide is in the locking position, the limiting portion abuts against the tightening surface to tighten the locking rod into the fixed seat where it is located.

[0015] Further preferably, a rack is provided on the driving slide, and matching teeth are provided on the locking rod. The rack meshes with the matching teeth and drives the locking rod to rotate when the driving slide switches between the preparatory position and the locking position.

[0016] On the basis of the above technical solution, preferably, it further comprises an elastic member, which is arranged in a fixing seat where the cone cylinder is located and one end of which is connected to the cone cylinder, and is used to squeeze the cone cylinder to move toward the locking surface.

[0017] On the basis of the above technical solution, preferably, the conical cylinder and the locking wedge form a lock seat assembly, the positioning head and the locking rod form a lock hook assembly, and the number of the lock seat assembly and the lock hook assembly are both two, and are respectively arranged on two fixed seats.

[0018] On the other hand, the present invention provides a mechanical electrical connection device, including a plug, a socket and the above-mentioned mechanical locking and releasing mechanism, wherein the plug and the socket are respectively arranged on two fixed seats and are arranged opposite to each other, and when the locking surfaces of the two fixed seats are in contact, the plug is inserted into the socket and an electrical connection is formed.

[0019] On the basis of the above technical solution, preferably, it further comprises two bases and two sets of protective covers, wherein:

[0020] The two bases are fixed on the two fixing bases respectively, and the plug and the socket are arranged on the two bases respectively;

[0021] The two groups of protection covers are respectively arranged on two fixing seats, and the protection covers are used to cover the outside of the plug and the socket after the plug and the socket are separated.

[0022] Further preferably, it also includes two groups of linkage components, which are respectively arranged on two bases, and the two groups of linkage components are respectively connected to the two groups of protective covers in transmission. The linkage components include transmission parts. When the two bases are close to each other, the transmission parts of the two groups of linkage components resist each other and respectively drive the two groups of protective covers to open.

[0023] On the other hand, the present invention provides a lifting device, comprising the above-mentioned mechanical and electrical connection device.

[0024] The mechanical locking and releasing mechanism, mechanical electrical connection device and lifting equipment of the present invention have the following beneficial effects compared with the prior art:

[0025] (1) The two fixed seats are the two parts of the lifting equipment that need to be docked. The positioning head is inserted into the cone, and the locking wedge is inserted into the annular locking groove of the positioning head to fix the positioning head. At the same time, the locking rod is inserted into the locking hole and the cone is locked by rotation, and then the locking wedge is fixed by the cone to achieve stable mechanical docking and locking. When separation and release are required, the locking rod is rotated to align with the locking hole and move toward the cone, pushing the cone to make the locking wedge slide away from the annular locking groove, thereby releasing the positioning head and completing the separation and release action, thereby achieving rapid docking locking and separation and release actions. It can directly cooperate with the electric control drive to realize automatic action, without manual auxiliary docking or separation, further reducing the danger of operation;

[0026] (2) A push surface and a tightening surface are arranged on the driving slide, and two inclined surfaces are arranged on the locking rod to cooperate with the push surface and the tightening surface respectively. One of the inclined surfaces is located at the end of the locking rod, and contacts the push surface when the driving slide is in the preparation position and the release position, while the other inclined surface is arranged on the limiting portion. When the driving slide is in the locking position, the inclined surface is in contact with the tightening surface. When the driving slide moves from the preparation position to the locking position, the tightening surface will squeeze the limiting portion through the inclined surface, so that the locking rod is tightened toward the fixed seat where the locking rod is located. During the tightening process, the cone cylinder is fixed to complete the relative fixation of the cone cylinder, thereby completing the state switching of the locking rod under different working requirements through a single structure;

[0027] (3) The mechanical and electrical connection device provided can perform electrical connection during the mechanical docking process. When the two fixing seats are close to each other and locked, the plug is synchronously inserted into the socket to form an electrical and mechanical synchronous connection between the two parts of the lifting equipment, thereby further reducing the difficulty of manual operation and improving the operating efficiency of the lifting equipment during assembly and separation;

[0028] (4) Two groups of linkage components are provided and respectively provided on two bases, and the two groups of linkage components are respectively connected to the two groups of protective covers in a transmission manner, wherein the linkage components include a transmission part. When the two bases are close to each other, the transmission parts of the two groups of linkage components abut against each other and respectively drive the two groups of protective covers to open, thereby realizing the opening and closing of the protective covers during mechanical docking and release through linkage control of the two groups of linkage components.

[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-6 As shown, the mechanical locking and releasing mechanism of the present invention comprises a fixing seat 1, a cone 2, a locking wedge 3, a positioning head 4 and a locking rod 5.

[0041] There are two fixing seats 1, and both have locking surfaces. The locking surfaces of the two fixing seats 1 fit together. The locking surfaces of the two fixing seats 1 are the same in shape and size and are arranged in a plane so that the two locking surfaces can fit completely together, thereby completing the mechanical docking of the two fixing seats 1. It should be noted that the two fixing seats 1 can be respectively arranged on the two parts of the lifting equipment to be spliced, and the connection of the two parts of the lifting equipment is achieved by docking the two fixing seats 1.

[0042] The cone cylinder 2 is arranged in one of the two fixing seats 1, and a socket is provided on the locking surface of the fixing seat 1, the bottom surface of the cone cylinder 2 faces the locking surface, a locking hole 201 is provided on the axis of the cone cylinder 2, and the locking hole 201 is opposite to the socket, the cone cylinder 2 is arranged in a cone shape as a whole, and the interior is hollow, and its bottom surface is open, the outside of the cone cylinder 2 is hollow, and the locking hole 201 is opened at the top of the cone cylinder 2. In this embodiment, the shape of the locking hole 201 consists of a circle and two squares, and the two squares are symmetrically arranged on both sides of the circle. In addition, a plurality of first guide protrusions are arranged on the cone cylinder 2, and the first guide protrusions are arranged in a T shape, and the length direction coincides with the direction of the busbar on the inner wall of the cone cylinder 2.

[0043] The locking wedge 3 is slidably arranged on the cone cylinder 2 and the fixed seat 1, and the locking wedge 3 can slide along the generatrix direction of the cone cylinder 2 and parallel to the locking surface. In the present embodiment, the number of locking wedges 3 is set to four, and they are arranged in a ring-shaped distribution around the center line of the socket. Each locking wedge 3 is provided with a first guide groove, and the first guide protrusion on the cone cylinder 2 is inserted into the first guide groove, so that the locking wedge 3 can slide along its generatrix relative to the cone cylinder 2. At the same time, a second guide protrusion is provided on the locking wedge 3, which is also a T-shaped arrangement. Four second guide grooves arranged along the radial direction of the socket are provided on the corresponding fixed seat 1, and the second guide protrusion is inserted into the second guide groove, so that the locking wedge 3 can move along the radial direction of the socket on the fixed seat 1. When the cone cylinder 2 cooperates with the locking wedge 3, the cone cylinder 2 moves, which can drive the locking wedge 3 to move along its generatrix, and during the movement, drives the locking wedge 3 away from or close to the socket.

[0044] The positioning head 4 is fixed on the locking surface of another fixed seat 1 and inserted into the socket of the fixed seat 1 where the cone 2 is located. An annular locking groove 401 is provided on the outside of the positioning head 4, and the locking wedge block 3 is inserted into the annular locking groove 401 to relatively fix the positioning head 4 and the fixed seat 1 where the locking wedge block 3 is located.

[0045] In this embodiment, the positioning head 4 is a columnar structure raised on the locking surface, and its end is truncated. The inclined surface arranged on the positioning head 4 can push the four locking wedges 3 away from the socket when inserted into the socket. When the positioning head 4 is fully inserted into the socket, the four locking wedges 3 can be inserted into the annular locking groove 401 to lock the positioning head 4, thereby preventing it from moving axially. In order to improve the fit between the locking wedges 3 and the annular locking groove 401 on the positioning head 4, the four locking wedges 3 are arranged in an arc shape of nearly ninety degrees on one side facing the annular locking groove 401, and are adapted to the annular locking groove 401 to maximize the contact area between the locking wedges 3 and the positioning head 4 when locking the positioning head 4, thereby improving the stability of the mechanical locking.

[0046] The locking rod 5 is arranged on the fixing seat 1 where the positioning head 4 is located, and the central axis is perpendicular to the locking surface. The locking rod 5 can rotate and axially move relative to the fixing seat 1 where the positioning head 4 is located. The locking rod 5 is provided with a locking head 51 and abutting surface 501. The locking head 51 is inserted into the locking hole 201, and cooperates with the abutting surface 501 to prevent the locking rod 5 from axially moving relative to the cone 2. The locking head 51 is adapted to the locking hole 201. The end of the locking head 51 is arranged in a conical shape, and its cross section is the same as the shape of the locking hole 201. When the locking head 51 is aligned with the lock hole 201, the locking head 51 is locked. After the locking head 51 is inserted into the locking hole 201, it can pass through the locking hole 201. Correspondingly, when the locking head 51 is misaligned with the locking hole 201, the locking head 51 cannot pass through the locking hole 201. That is to say, after the locking head 51 passes through the locking hole 501 and rotates with the locking rod 5, the locking rod 5 and the conical cylinder 2 can be relatively locked by cooperating with the abutting surface 501 and the locking head. In addition, two limit blocks are provided on the side of the conical cylinder 2 away from the locking rod 5. The two limit blocks are both located on the outside of the locking hole 201, and are used to block the locking head 51, so that the locking rod 5 can only reciprocate by ninety degrees.

[0047] In this embodiment, when separation is released, the locking rod 5 rotates and aligns the locking head 51 with the locking hole 201, pushing the cone 2 to move through the abutting surface 501, so that the locking wedge 3 slides away from the annular locking groove 401, and at the same time, the locking head 51 leaves the locking hole 201, the positioning head 4 leaves the socket, and the locking surfaces of the two fixed seats 1 are separated.

[0048] On the contrary, when docking and locking, the locking rod 5 passes through the socket and the locking hole 201 in turn, and the positioning head 4 opens the locking wedge 3, and the locking head 51 rotates, so that the locking rod 5 and the cone 2 are relatively locked. At this time, the locking rod 5 retracts, driving the cone 2 to move, and the locking wedge 3 is inserted into the annular locking groove 401 to lock the positioning head. At this time, the locking surfaces of the two fixing seats 1 are in contact with each other, and the two fixing seats 1 complete the docking and locking.

[0049] As a preferred embodiment, a driving slide 6 is also provided. The driving slide 6 is slidably provided in the fixed seat 1 where the locking rod 5 is located, and is transmission-connected to the locking rod 5. A locking position, a preparatory position and a releasing position are provided in the fixed seat 1. When the driving slide 6 is in the locking position, the locking head 51 is misaligned with the locking hole 201, and the cone 2 is relatively fixed to the fixed seat 1 where it is located. When the driving slide 6 is in the preparatory position, the locking head 51 is opposite to the locking hole 201. When the driving slide 6 is in the releasing position, the abutting surface 501 on the locking rod 5 pushes the cone 2 to move to the side away from the locking surface.

[0050] Since the locking rod 5 needs to have three states and can be switched among these three states, the driving slide 6 is provided to be used for switching the three states of the locking rod 5. The three states of the locking rod 5 are respectively a locked state, a pre-docking state and a released state. The three states correspond to the locked position, the pre-docking position and the released position of the driving slide 6 in the fixed seat 1, respectively. When the locking rod 5 is in the locked state, the locking head 51 passes through the locking hole 201 and rotates ninety degrees, and the cone cylinder 2 is locked by the locking head 51 and the abutting surface 501. When the locking rod 5 is in the pre-docking state, the locking head 51 can be inserted into the locking hole 201, and it will not push the cone cylinder 2 to move, so that the locking rod 5 can be directly inserted into the locking hole 201 for docking. When the locking rod 5 is in the released state, relative to its pre-docking state, it will extend out of the fixed seat 1 where it is located by a certain distance, and push the cone cylinder 2 away from the locking surface through the abutting surface 501, thereby driving the multiple locking wedges 3 to move toward the side away from the socket to leave the annular locking groove 401.

[0051] Since the preparatory docking state of the locking rod 5 is an intermediate state between the other two states, the preparatory position is set between the locking position and the releasing position, and the sliding seat 6 is driven to move back and forth to switch between the three positions, thereby changing the state of the locking rod 5.

[0052] Specifically, a pushing surface 601 and a tightening surface 602 are provided on the driving slide 6, and the pushing surface 601 is in contact with an end of the locking rod 5 away from the locking head 51. The pushing surface 601 is used to push the locking rod 5 to move toward the fixed seat 1 where the cone 2 is located. The locking rod 5 also includes a limiting portion 52. When the driving slide 6 is in the locking position, the limiting portion 52 abuts against the tightening surface 602 to tighten the locking rod 5 into the fixed seat 1 where it is located.

[0053] The driving slide 6 as a whole is a frame-like structure, and one end of the locking rod 5 extends to the interior of the driving slide 6. Two inclined surfaces are arranged on the locking rod 5, which are respectively used to cooperate with the pushing surface 601 and the tightening surface 602. One of the inclined surfaces is located at the end of the locking rod 5, and contacts the pushing surface 601 when the driving slide 6 is in the preparation position and the release position, and the other inclined surface is arranged on the limiting portion 52. The inclined surface fits the tightening surface 602 when the driving slide 6 is in the locking position. Specifically, when the driving slide 6 moves from the preparation position to the locking position, the tightening surface 602 will squeeze the limiting portion 52 through the inclined surface, so that the locking rod 5 is tightened toward the fixed seat 1 where the locking rod 5 is located, and the cone cylinder 2 is fixed during the tightening process to complete the relative fixation of the cone cylinder 2.

[0054] In addition, when driving the slide 6 from the preparation position to the release position, the pushing surface 601 will cooperate with the inclined surface at the end of the locking rod 5 to push the locking rod 5 out of the fixed seat 1 where it is located, thereby pushing the cone 2 to move and releasing the mechanical docking part.

[0055] Considering that the locking rod 5 needs to cooperate in rotating when the driving slide 6 moves between the preparation position and the locking position, and according to the structure set in this embodiment, the locking rod 5 needs to be able to rotate back and forth ninety degrees, a rack 603 is provided on the driving slide 6, and a matching tooth 502 is provided on the locking rod 5. The rack 603 meshes with the matching tooth 502, and drives the locking rod 5 to rotate when the driving slide 6 switches between the preparation position and the locking position.

[0056] The center angle of the matching tooth 502 provided on the locking rod 5 is ninety degrees, so that when the locking rod 5 switches between the preparatory position and the locking position, the locking rod 5 can rotate back and forth ninety degrees. It should be noted that since the relative angles of the locking rod 5 in the preparatory position and the locking position are different, the two inclined surfaces provided on the locking rod 5 are not parallel to each other.

[0057] In this embodiment, an elastic member 7 is also provided. The elastic member 7 is arranged in the fixed seat 1 where the cone cylinder 2 is located, and one end is connected to the cone cylinder 2. The elastic member 7 is used to squeeze the cone cylinder 2 to move toward the locking surface. Through the elastic member 7, after the positioning head 4 is inserted into the socket, the elastic member 7 can press the cone cylinder 2 to move, thereby driving the locking wedge 3 to insert into the annular lock groove 401. It should be noted that the locking hole 201 on the cone cylinder 2 is located between the locking head 51 and the abutting surface 501 at this time, and the elastic member 7 can be selected as a spring.

[0058] The cone 2 and the locking wedge 3 form a lock seat assembly, and the positioning head 4 and the locking rod 5 form a lock hook assembly. The number of the lock seat assembly and the lock hook assembly are both two, and they are respectively arranged on two fixed seats 1.

[0059] Taking into account the influence of factors such as the space of the structural layout and the connection stability, a lock seat assembly and a lock hook assembly are arranged on a single fixed seat 1 at the same time, so that the two fixed seats 1 can be locked through the one-to-one connection between the lock seat assembly and the lock hook assembly, thereby improving the connection stability and avoiding rotational deviation at the connection. Taking into account the space occupancy, the lock seat assembly and the lock hook assembly can be staggered to increase the contact area of ​​the two locking surfaces.

[0060] In order to promote the driving slide 6 to switch back and forth between the three positions, a nut is fixed on the driving slide 6, and a screw rod is arranged on the fixed seat 1 along the moving direction of the driving slide 6. The screw rod is threadedly connected to the nut, and the screw rod rotates to drive the slide 6 to move horizontally through the nut. At the same time, in order to enable the screw rod to be connected to the driving device or operated manually, a reducer can be arranged on the outside of the fixed seat 1, and the output end of the reducer is connected to the screw rod, thereby improving the convenience of operation.

[0061] like Figure 1-9As shown, the mechanical electrical connection device of the present invention includes a plug 8, a socket 9 and the above-mentioned mechanical locking and releasing mechanism. The plug 8 and the socket 9 are respectively arranged on two fixing seats 1 and are arranged opposite to each other. When the locking surfaces of the two fixing seats 1 are fitted together, the plug 8 is inserted into the socket 9 and an electrical connection is formed.

[0062] After the mechanical docking is completed, there is still an electrical connection part that needs to be connected. Therefore, an electrical connection structure is set up on the basis of the above-mentioned mechanical locking and releasing mechanism to form the present mechanical electrical connection device. Specifically, when the two fixing seats 1 are close to each other and locked, the plug 8 is synchronously inserted into the socket 9 to form an electrical and mechanical synchronous connection between the two parts of the lifting equipment. It should be noted that after the two locking surfaces are fully fitted, the plug 8 is fully inserted into the socket 9.

[0063] In this embodiment, two bases 10 and two sets of protective covers 11 are also provided. The two bases 10 are respectively fixed on the two fixing bases 1, and the plug 8 and the socket 9 are respectively provided on the two bases 10. The two sets of protective covers 11 are respectively provided on the two fixing bases 1. The protective covers 11 are used to cover the outside of the plug 8 and the socket 9 after the plug 8 and the socket 9 are separated.

[0064] The two bases 10 are respectively fixed on the outside of the two fixing bases 1 and are located on the same straight line in the docking direction. The base 10 includes a protective shell. The outer part of the protective shell is spherical and has an opening on one side. The openings of the two protective shells are arranged facing each other. The plug 8 and the socket 9 are respectively embedded in the opening sides of the two protective shells. In order to achieve accurate docking of the plug 8 and the socket 9, positioning pins and positioning sleeves are also respectively arranged on the two protective shells to achieve positioning of the plug 8 and the socket 9 before and after docking.

[0065] The protective cover 11 includes two protective parts, the curvature of the two protective parts is consistent with the curvature of the protective shell, and both ends of the protective parts are hinged to the outside of the protective shell. The connecting line at the hinge passes through the center of the sphere of the protective shell, and after the two protective parts are covered on the protective shell, the opening of the protective shell can be completely closed, thereby protecting the plug 8 and the socket 9.

[0066] In this embodiment, the protective cover 11 is closed and set on the base 10 when the two fixing bases 1 are separated. When the two fixing bases 1 are close to each other for docking, the protective cover 11 is opened to allow the plug 8 and the socket 9 to dock, thereby achieving mechanical and electrical synchronous docking.

[0067] In order to enable the two groups of protection covers 11 to be opened synchronously when docking, and to be closed synchronously when separating to protect the plug 8 and the socket 9, as a preferred embodiment, two groups of linkage components 12 are further provided, the two groups of linkage components 12 are respectively provided on the two bases 10, and the two groups of linkage components 12 are respectively connected to the two groups of protection covers 11 in transmission connection, the linkage components 12 include a transmission part 121, when the two bases 10 are close to each other, the transmission parts 121 of the two groups of linkage components 12 abut against each other, and respectively drive the two groups of protection covers 11 to open.

[0068] The opening and closing of the protective cover 11 are realized by linkage control through two groups of linkage components 12. Specifically, the two linkage components 12 form a group. The linkage component 12 also includes a linkage rod and a base rod. The transmission part 121 is sleeved on the outside of the base rod and can slide on the outside of the base rod. A spring connected to the transmission part 121 is arranged on the base rod. There are two linkage rods, which are respectively hinged on the two protective parts of the protective cover 11.

[0069] A group of linkage components 12 is provided on each base 10, and the transmission parts 121 of the two groups of linkage components 12 are located on the same straight line. When the two fixed bases 1 are close to each other, the transmission parts 121 of the two groups of linkage components 12 contact and squeeze each other, and the transmission parts 121 move relative to the fixed base 1, thereby driving the linkage rod to rotate, and then under the push of the linkage rod, the protective cover 11 is opened to realize the automatic opening of the protective cover 11 during the docking process. Conversely, under the action of the spring, the spring pushes the transmission part 121 to reset when separated, so that the protective cover 11 is closed again.

[0070] In addition, a protective cover is provided on one of the two bases 10.
