DETAILED DESCRIPTION

[0023] 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.

[0024] Example: See Figures 1 to 6 According to an embodiment of the utility model, a technical solution is provided: an elevator support load-bearing beam for an elevator shaft, comprising a beam body 1 and a body 2, and also comprising a fixed seat 3, which is fixed on the beam body 1, and the fixed seat 3 is provided with a placement groove 4 along its length direction; a locking rod 5, which is hinged on the fixed seat 3, and a mounting seat 18 is placed on the fixed seat 3, and the body 2 is mounted on the mounting seat 18, and the mounting seat 18 is provided with a receiving groove 6 suitable for accommodating the locking rod 5; and a locking mechanism 7, which is arranged at the free end of the locking rod 5, and can selectively fix the locking rod 5 and the mounting seat 18 relative to each other to limit or allow the locking rod 5 to move relative to the mounting seat 18.

[0025] The elevator shaft elevator supports the load-bearing beam with the above structure. When the user needs to install the mounting seat 18 on the beam body 1, the user first places the mounting seat 18 on the fixed seat 3 on the beam body 1, and then pulls up the locking rod 5 and rotates the locking rod 5 into the receiving groove 6. At this time, the locking mechanism 7 is used to relatively fix the locking rod 5 and the mounting seat 18 to complete the installation operation of the mounting seat 18. When the user wants to remove the mounting seat 18 from the beam body 1, the locking mechanism 7 is used to release the relative fixed state of the locking rod 5 and the mounting seat 18, and then the locking rod 5 is separated from the receiving groove 6 to complete the removal of the mounting seat 18. The structure is simple and convenient and fast.

[0026] In this embodiment, the locking mechanism 7 includes an abutment portion 8, a clamping portion 9, a limiting portion 10 and a spring 11. The abutment portion 8 is slidably sleeved on the locking stick 5, the limiting portion 10 is fixed to the free end of the locking stick 5, the spring 11 is sleeved on the locking stick 5, the two ends of the spring 11 are respectively fixed to the abutment portion 8 and the limiting portion 10, the clamping portion 9 is fixed to the side of the abutment portion 8 away from the limiting portion 10, and the mounting seat 18 is provided with a clamping groove 12 suitable for inserting the clamping portion 9; when the locking stick 5 is in the receiving groove 6 When the mounting base 18 needs to be removed from the beam body 1, the abutting portion 8 is slid toward the free end of the locking stick 5 to disengage the clamping portion 9 from the clamping groove 12. At this time, the locking stick 5 is disengaged from the accommodating groove 6 to complete the disassembly of the mounting base 18.

[0027] In this embodiment, a plurality of friction-increasing protrusions 13 are provided on the clamping portion 9 along its length direction at intervals; when the clamping portion 9 is inserted into the clamping groove 12, the friction-increasing protrusions 13 increase the friction between the clamping portion 9 and the clamping groove 12. The increase in friction helps to prevent the clamping portion 9 from slipping out of the clamping groove 12 when subjected to external force, thereby improving the stability and reliability of the connection.

[0028] In this embodiment, a magnetic attraction component 14 is protruded from the free end of the clamping portion 9, and the magnetic attraction component 14 is suitable for adsorbing the mounting seat 18; when the clamping portion 9 is inserted into the clamping groove 12 and contacts the mounting seat 18, the magnetic attraction component 14 will use its magnetism to adsorb on the mounting seat 18, thereby further enhancing the connection force between the clamping portion 9 and the mounting seat 18.

[0029] In this embodiment, a bearing portion 15 is protruded on the peripheral side wall of the abutment portion 8, and a pull rod 16 is provided on the bearing portion 15; when the user slides the abutment portion 8 toward the free end of the locking rod 5, the pull rod 16 will provide the user with a fulcrum for pulling the abutment portion 8, so that the user can easily move the abutment portion 8 by holding the pull rod 16 and applying force.

[0030] In this embodiment, a limiting ball 17 is provided at the free end of the pull rod 16; when the user holds the pull rod 16, the user's palm may gradually separate from the pull rod 16 due to insufficient friction. At this time, the limiting ball 17 will block the user's palm to prevent the user's palm from separating from the pull rod 16.

[0031] Working principle: when the user needs to install the mounting seat 18 on the beam body 1, the user first places the mounting seat 18 on the fixed seat 3 on the beam body 1, and then pulls up the locking rod 5 and rotates the locking rod 5 into the receiving groove 6. At this time, the abutting portion 8 slides toward the free end of the locking rod 5 to align the clamping portion 9 with the clamping groove 12 and insert it, and then releases the abutting portion 8. At this time, the abutting portion 8 will be elastically abutted on the mounting seat 18 by the spring 11, and the installation operation of the mounting seat 18 can be completed. When the user wants to remove the mounting seat 18 from the beam body 1, the abutting portion 8 slides toward the free end of the locking rod 5 to disengage the clamping portion 9 from the clamping groove 12, and then, the locking rod 5 is disengaged from the receiving groove 6, and the removal of the mounting seat 18 can be completed. The structure is simple, convenient and fast; when the clamping portion 9 is inserted into the clamping groove 12, the friction-increasing protrusion 13 will increase The friction between the clamping part 9 and the clamping slot 12 is increased. The increase in friction helps to prevent the clamping part 9 from slipping out of the clamping slot 12 when subjected to external force, thereby improving the stability and reliability of the connection; when the clamping part 9 is inserted into the clamping slot 12 and contacts the mounting seat 18, the magnetic attraction part 14 will use its magnetism to adsorb on the mounting seat 18, thereby further enhancing the connection force between the clamping part 9 and the mounting seat 18; when the user slides the abutting part 8 toward the free end of the locking stick 5, the pull rod 16 will give the user a fulcrum for pulling the abutting part 8, so that the user can easily move the abutting part 8 by holding the pull rod 16 and applying force; when the user holds the pull rod 16, the user's palm may gradually separate from the pull rod 16 due to insufficient friction. At this time, the limiting ball 17 will block the user's palm to prevent the user's palm from separating from the pull rod 16.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
